AIM Ropeginterferon alfa-2b is a new site-specific conjugated 40 kDa branched polyethylene-glycol recombinant interferon (IFN). The aim of the study was to determine its safety, pharmacokinetics (PK) and pharmacodynamic (PD). METHODS Ropeginterferon alfa-2b was evaluated first in human in 48 healthy male volunteers after a single dose subcutaneous injection by either 24, 48, 90, 180, 225, 270mcg of the product or 180mcg of marketed pegylated (peg)-IFN alfa-2a. Within each dosing group, 6 subjects received ropeginterferon alfa-2b and 2 subjects received peg-IFN alfa-2a. RESULTS Dose-related increases in ropeginterferon alfa-2b PK parameters (Cmax, AUC, and AUC0-t) were observed over the dose range 24 to 270mcg. The geometric mean values for these PK parameters of ropeginterferon alfa-2b were higher than that of peg-IFN alfa-2a at the 180mcg dose level of 176%, 166%, and 182%, respectively. Mean PD parameters (Emax, Tmax, and AUC0-t) for ropeginterferon alfa-2b increased with dose for both biomarkers neopterin and 2’, 5’-OAS. Ropeginterferon alfa-2b has similar PD profiles as peg-IFN alfa-2a. The treatment related adverse events are similar between the two study drugs, but the overall incidence was numerically lower for ropeginterferon alfa-2b (83%) than peg-IFN alfa-2a (100%) at the 180mcg dose level. CONCLUSIONS Single subcutaneous dose of Ropeginterferon alfa-2b of up to 270mcg is safe and well tolerated. It displays dose related increase in PK and PD parameters, potentially less frequent injection, and better safety profiles. Ropeginterferon alfa-2b is being developed for diseases in which previous peg-IFN use has been limited by side effects.

Despite efforts to deal with life's economic issues on a daily basis, the majority of Ghanaians are financially vulnerable. This has made pursuing lifelong ambitions more difficult. Given these realities, it is reasonable to believe that financial literacy and consumer financial stability will be a successful strategy for promoting economic stability. Financial literacy is pivotal for making informed financial decisions at both the household and macroeconomic levels. A high human development index score indicates that persons who make up the country's population are in good health. As a result, linking household decisions to broader policy outcomes becomes increasingly vital. This research aims to find a link between financial literacy and consumer financial stability as well as their relationship with macroeconomic stability. Financial literacy has a significant association with economic stability as measured by citizens' welfare. This discovery has several ramifications for financial literacy initiatives. In addition, consumer financial wellness has an insignificant positive impact on national economic stability. Nonetheless, it demonstrates how a financially sound consumer can boost aggregate demand by spending more, impacting job creation and macroeconomic growth. The Probit-Regression Model facilitated data analysis using a participant population of 960 across eight studied regions in Ghana. This study believes that national governments should take the favourable correlations between financial literacy and consumer financial stability on the one hand, and national economic stability on the other, seriously. As a result, policy efforts should consider the relationship between microeconomic actions and macroeconomic outcomes since the former is observed to influence the latter.

Objective There is a lack of studies comparing Procalcitonin (PCT), C-reactive protein (CRP) and white blood cell (WBC) levels in the differential diagnosis of acute bacterial, viral, and mycoplasmal respiratory infections. It is necessary to explore the correlation between above markers and different types of acute respiratory tract infections (ARTI). Methods 108 children with confirmed bacterial infection were regarded as group A, 116 children with virus infection were regarded as group B, and 122 children with mycoplasma infection were regarded as group C. The levels of PCT, CRP and WBC of the three groups were detected and compared. Results The levels of PCT, CRP and WBC in group A were significantly higher than those in groups B and C (P <0.05). The positive rate of combined detection of PCT, CRP and WBC was significantly higher than that of single detection. There was no significant difference of PCT, CRP and WBC levels between the group of Gram-positive (G+) bacteria infection and Gram-negative (G-) bacteria infection (P >0.05). ROC curve results showed that the area under the curve (AUC) of PCT, CRP and WBC for the diagnosis of bacterial respiratory infections were 0.65, 0.55, and 0.58, respectively. Conclusions PCT, CRP and WBC can be used as effective indicators for the identification of acute bacterial or no-bacterial infections in children. The levels of PCT and CRP have higher differential diagnostic value than that of WBC in infection, and the combined examination of the three is more valuable in clinic.

Background: Women with missed Obstetric anal sphincter injuries (OASIs) are at an increased risk of anal incontinence. Objective: To assess the accuracy of 3D Transperineal Ultrasound (TPUS) compared with clinical examination for detecting OASIs. Design: Prospective Observational longitudinal cohort study. Setting: District General Hospital, UK. Population or sample: Women undergoing their first vaginal delivery immediately postpartum. Methods: Perineal trauma was initially assessed by accouchers and women were then re-examined by a trained research fellow. A 3D TPUS was performed immediately after delivery before suturing to look for OASIs. Main outcome measures: OASIs on clinical examination and on TPUS Main Results: Two hundred and sixty-four women participated and two hundred and twenty-six (86%) delivered vaginally. Twenty-one (9%) sustained OASIs. Six (29%) of these tears were missed by the accoucher but were identified by the trained research fellow. TPUS identified 19 of the 21 (90.5%) OASIs. One percent (n = 2) had sonographic appearances of an anal sphincter defect and were not seen clinically. The positive and negative predictive of TPUS to detect OASIs were 91% and 99% respectively. TPUS identified 91% of OASIs compared to 71% detected by the accoucher. However, this was not statistically significant. Conclusions: More OASIs were identified on TPUS compared to examination. TPUS may have role in improving the detection rate of OASIs. Considering immense training and financial implications of using TPUS, attention needs to be focused on training to accurately identify anal sphincter defects on clinical examination. Funding:none Keywords: transperineal ultrasound imaging, obstetric anal sphincter injury

1. Silicon mediated plant–herbivore interactions have gained increasing recognition and have now been studied in a wide range of species. Many studies have also considered accumulation of Si by plants as a process largely driven by geo-hydrological cycles. 2. To identify factors driving the water - plant Si - herbivore nexus we analysed the concentration of Si in fibrous tussock sedge (Carex appropinquata), the population density of the root vole (Microtus oeconomus) and the ground water level, over 11 years. 3. The largest influence of autumn Si concentration in leaves (Sileaf) was the level of the current year’s ground water table, which accounted for 13.3% of its variance. The previous year’s vole population density was weakly positively correlated with Sileaf and alone explained 9.5% of its variance. 4. The only variable found to have a positive, significant effect on autumn Si concentration in rhizomes (Sirhiz) was the current year spring water level explaining as much as 60.9% of its variance. 5. We conclude that the changes in Si concentration in fibrous tussock sedge are predominantly driven by hydrology, with vole population dynamics being secondary. Our results provide only partial support for the existence of plant-herbivore interactions, as we did not detect the significant effects of Si tussock concentration on the vole density dynamics. This was mainly due to low level of silification of sedges, which was insufficient to impinge herbivores. Future studies on plant–herbivore interactions should therefore mainly focus on identification of mechanisms and conditions allowing plants to accumulate silica at the levels sufficient to act as an anti-herbivore protection.

Background and Purpose Ferroptosis is a new form of cell death discovered in recent years. PH is a pulmonary circulatory disease partially characterized by small pulmonary vessel remodeling and fibrosis. However, researchers have not clearly determined whether ferroptosis is involved in PH. Here, this study examined the role and regulatory mechanism of ferroptosis in PH and pulmonary fibrosis. Experimental Approach To evaluate the occurrence of ferroptosis in rat PH models and in hypoxic PASMCs, MDA, GSH and iron assay were performed. The therapeutic potential of ferroptosis inhibitor fer-1 was evaluated using echocardiography, hemodynamic analysis and ventricular weight measurement in rat PH models. Ferroptosis-related molecule was determined by western blotting and RT-PCR. Changes in autophagy and fibrosis were analyzed by western blotting analysis, RT-PCR and immunofluorescence. Key Results Ferroptosis was existence in vivo and vitro PH models. The fer-1 significantly improved the pathological symptoms of PH and inhibited the occurrence of pulmonary vascular fibrosis. GPX4 was significantly lower expression in PH models, and serves as a key driver of PH-related ferroptosis. A KEGG pathway analysis and RT-PCR detection revealed that GPX4 drives ferroptosis in an autophagy-dependent manner. The RIP experiment verified that WTAP bound to the GPX4 pre-mRNA, induced m6A methylation and promoted its pre-mRNA degradation, thereby reducing the expression of GPX4 in hypoxic PASMCs. Conclusion and Implications This study proposed ferroptosis as a novel form of cell death in PH, and revealed the regulatory mechanism of the ferroptosis in PH, which is based on GPX4 m6A methylation regulated by WTAP.

Application of electrocautery to a metal guidewire can be used to perform transseptal puncture (TSP). Dedicated radiofrequency guidewires (RF) may represent a better alternative. This study compares safety and effectiveness of electrified guidewires to a dedicated RF wire. TSP was performed on porcine hearts using an electrified 0.014” or 0.032” guidewire under various power settings compared to TSP using a dedicated RF wire with 5W power. The primary endpoint was the number of attempts required to achieve TSP. Secondary endpoints included the rate of TSP failure, TSP consistency, effect of the distance between tip of the guidewire and the tip of the dilator, and effect of RF power output level. Qualitative secondary endpoints included tissue puncture defect appearance, thermal damage to the TSP guidewire or dilator, and tissue temperature using thermal imaging. The RF wire required 1.10 ± 0.47 attempts to cross the septum. The 0.014” electrified guidewire required 2.17 ± 2.36 attempts (2.0x higher than the RF wire; p<0.01), and the 0.032” electrified guidewire required 3.90 ± 2.93 attempts (3.5x higher than the RF wire; p<0.01). Electrified guidewires had a higher rate of TSP failure, larger defects, more tissue charring, higher temperatures, and greater tissue heating. Fewer RF applications were required to achieve TSP using a dedicated RF wire compared to an electrified guidewire. Smaller defects and lower tissue temperatures were also observed using the RF wire. Electrified guidewires required greater energy delivery and were associated with equipment damage and tissue charring.

Background: Many different internal factors have been proven to influence urine production such as age, weight, and quality of sleep. External factors such as consumption of caffeine and fluid consumption have been shown to have an impact on urine production. Aim: To investigate the impact of movement, physical activity, and position on urine production. Methods: This prospective observational study was executed at Ghent University Hospital, Belgium. Study participation was open for anyone visiting the hospital. Participants collected 1 basic and 2 extended 24-hour urine collections and filled in questionnaires concerning their general health and physical activity. Urinary levels of osmolality, sodium, and creatinine were determined. Data on movement, physical activity and position was described. Results: An increase in body movement leads to a significant increase in diuresis during daytime, night-time, and 24 hours (p=0,002, p= <0,001, and p=<0,001, respectively). An increase in body movement leads to a significant decrease in osmolality during night-time and 24 hours (p=0,009, and p=0,004, respectively). However, no significant influence of movement on osmolality was found during daytime (p=0,12). An increase in body movement leads to a significant decrease in creatinine during daytime, night-time, and 24 hours (p=0,001, <0,001, and p=<0,001, respectively). An increase in body movement leads to a significant increase in sodium during daytime (p=0,046) but this was statistically significant during night-time and 24 hours (p=0,32, and p=0,84 respectively). Conclusion: Our study demonstrates a statistically significant association of movement, physical activity, and position with urine production. It would therefore be interesting to explore this association further with the use of new technology to have more accurate data. Here lays a potential role for conservative measurements and lifestyle adaptations in the management of patients with bothersome LUTS and more precisely nocturia.

Objective: Chemotherapy and radiotherapy, used to treat childhood hematological malignancies (HM), can negatively impact oral tissues and organs. This study aimed to evaluate oral health-related quality of life in children with HM. Material and Methods: A total of 99 children, including 49 undergoing HM (41 for acute lymphocytic leukemia, 8 for acute myelocytic leukemia,) and 50 healthy volunteers, were included in this cross-sectional study. The mean age of the entire study group was 78.63 ± 34.41 months. The mean age of the HM and control groups was 87.12 ± 35.04 and 70.95 ± 34.85 months, respectively. The Simplified Oral Hygiene Index (SOHI), Decayed, Missing, and Filled Teeth (DMFT/dmft) index, and Turkish version of the Early Childhood Oral Health Impact Scale (ECOHIS-T) were administered to all children. The data were analyzed using SPSS software (version 22.0). Results: The age and gender distributions of the two groups were similar. The SOHI was significantly higher in the HM group, whereas the DMFT/dmft score was similar between the groups. No significant difference in the total ECOHIS-T score was observed between the two groups, but there was a group difference in the responses to questions on pain and psychological processes. Conclusions: Oral health and self-care were negatively affected by childhood HM and the treatment thereof. Close clinical dental follow-up of such patients is required.

Commentary on: LAPAROSCOPIC MYOMECTOMY USING LOOP LIGATION FOR GIANT INTRACERVICAL MYOMAS: A NOVEL SURGICAL TECHNIQUE.Authors: Shengke Wang, Dongdong Wang, Qihong Huang, Fujie Zhao.Journal: BJOG: An International Journal of Obstetrics & GynaecologyINTRACERVICAL FIBROID REMOVAL: A MYOMECTOMY REASONED ON BIOLOGICAL BASES .Dr. Andrea Tinelli, MD, Prof, PhDVeris delli Ponti Hospital, Obstetrics and Gynecology Department, Scorrano, Lecce, Italy; Laboratory of Human Physiology,Phystech BioMed School, Faculty of Biological & Medical Physics,Moscow Institute of Physics and Technology (State University), Dolgoprudny, Moscow Region, Russia.Tel: +39-3392074078; E-mail:andreatinelli@gmail.com; ORCID: 0000-0001-8426-8490Anatomically, uterine corpus, isthmus and cervix compose one organ, but functionally they attend different function during pregnancy and labor. The uterine cervix is mainly composed connective tissue and extracellular matrix, that allow the pregnancy to come to an end, up to the onset of labor, when cervical ripening and dilatation occur to deliver the fetus. The cervical innervations and the different neurotransmitters and neuropeptides expression involved in cervical ripening suggest that the cervix plays a key role in pregnancy maintenance, labor initiation, pain and delivery; this can also be supported by previous studies that showed that cervical ripening is also a neuroimmune-mediate inflammatory reaction involveing the hypogastric nerve [Di Tommaso S “et al”, 2017;18(2):140-148].Neuropeptides are signaling peptides that are produced by neural, endocrine and/or immune cells: all of these hormones are involved in a variety of biological processes, not only enhancing uterine contractility and modulating pain trigger, but also possessing anti-inflammatory, antioxidative stress and tumorigenic properties. Particularly, they contribute with changes in muscle contractility, uterine peristalsis and muscular healing and may be involved also in the uterine fibroids’ pathophysiology [Tinelli A “et al”; 2020;21(5):440-442].Uterine fibroids are generally distributed over the body and fundus of the uterus, they are surrounded by a fibroneurovascular network rich of neurotransmitters, the myoma pseudocapsule, a neurovascular bundle separating fibroid from the myometrium, and allowing less bleeding during myomectomy and better subsequent myometrial healing after removal [Tinelli A “et al”; Curr Protein Pept Sci. 2017;18(2):129-139]. For this reason, the correct myomectomy which enucleates fibroid inside its pseudocapsule has been called ”intracapsular” and has remarkable early and late biological - muscular advantages, during and after surgery [Tinelli A “et al”.; JSLS 2012;16(1):119-29].Cervical fibroids are infrequent, but often create significant problems during myomectomy, as, during the removal there can be intraoperative and late complications, such as massive bleeding and scarring fibrosis with all the repercussions on pregnancy and childbirth [Malvasi A “et al”; 2013;29(11):982-8.].Wang “et al” [Wang “et al”; BJOG 2021] proposed their intracervical myomectomy for large intracervical myomectomy on 12 patients, basing on biology of the myoma pseudocapsule. They performed a laparoscopic myomectomy putting a loop ligation along the junction of the pseudocapsule and cervix, pulling the loop it at this position; then, they performed a traction and enucleation within the fibroid wound cavity directly closes the fibroid cavity, with the surrounding vascular network bounded in the knot after ligation of the pseudocapsule without dead space, and preventing injury to nearby tissues.During fibroid enucleation, loop ligation of the pseudocapsule glides along the tumor body and operates within the fibroid wound cavity, with no cervical tissue involved during enucleation. The neurovascular bundles of the fibroid pseudocapsule are protected and spared during myomectomy and the side of the pseudocapsule attached to the fibroid was bound tightly in the loop to achieve hemostasis. This technique results less invasive and would promote fertility in case of cervical myomectomy, not requiring additional pelvic dissection and allowing to operate directly in the cervix sparing adjacent tissues and pseudocapsule.

Coloboma, a congenital disorder characterized by gaps in ocular tissues, is caused when the choroid fissure fails to close during embryonic development. Several loci have been associated with coloboma, but these represent less than 40% of those that are involved with this disease. Here, we describe a novel coloboma-causing locus, BMP3. Whole exome sequencing and Sanger sequencing of patients with coloboma identified three variants in BMP3, two of which are predicted to be disease causing. Consistent with this, bmp3 mutant zebrafish have aberrant fissure closure. bmp3 is expressed in the ventral head mesenchyme and regulates phosphorylated Smad3 in a population of cells adjacent to the choroid fissure. Furthermore, mutations in bmp3 sensitize embryos to Smad3 inhibitor treatment resulting in open choroid fissures. Micro CT scans and Alcian blue staining of zebrafish demonstrate that mutations in bmp3 cause midface hypoplasia, suggesting that bmp3 regulates cranial neural crest cells. Consistent with this, we see active Smad3 in a population of periocular neural crest cells, and bmp3 mutant zebrafish have reduced neural crest cells in the choroid fissure. Taken together, this data suggests that Bmp3 controls Smad3 phosphorylation in neural crest cells to regulate early craniofacial and ocular development.

Background: Poor mental health is known to adversely affect functional abilities, social isolation and quality of life (QoL). It is, therefore, crucial to consider the long-term impacts of mental health conditions as autistic adults grow older. Objectives: To explore, in a group of community-based autistic adults, the extent of: (i) autistic traits, co-occurring physical and mental health conditions; (ii) age-related differences in those conditions, and changes over time; and (iii) their impact on everyday living and QoL. Method: 68 autistic adults (aged 19-80 years) participated in the first study (T1); 49 participants from T1 took part in a follow-up at T2 (mean retest interval 2.4 years). Standardised self-report measures of autistic traits, mental health and QoL were completed at both time points. Results: Over two-thirds (71%) of autistic adult participants experienced at least one co-occurring condition, and over a third (37%) met the criteria for three or more co-occurring conditions. Mental and physical health difficulties were related to autistic traits and difficulties in everyday life and were consistent predictors of poor QoL at T1 and T2. Conclusion: Mental health difficulties in autism persisted into older age and did not improve over time. These findings have important implications for mental health provision for autistic adults in older age.Pre-print article

Background and aim India has declared mucormycosis as an epidemic. The incidence rate is rising day by day as there are more than 29000 cases in 28 states until March 2021. COVID-19 is already burdening the health care system, and post-COVID mucormycosis leads to mortality and morbidity in patients treated with COVID-19. This article aims to understand the various complications of mucormycosis and how it is impacting COVID-19 infected patients. Methods A thorough literature search was performed using PubMed, Google Scholar, and Embase from May 2021 to June 2021. The authors selected the articles based on relevance. Mucormycosis, black fungus, fungal infection, COVID-19, pathogenesis, corticosteroids, treatment, antifungals were the major keywords searched. Secondary resources included from the published news articles. Results Through the literature, we observed that patients after COVID-19 are more vulnerable to these fungal infections, especially immunocompromised patients, patients with long-term steroid use, and uncontrolled diabetes. This review enlightens the manifestations, pathogenesis, and various treatment and anticipation policies for mucormycosis. Conclusion Awareness about the possibility of the disease is necessary to reduce the delay of diagnosis and timely treatment to prevent further implications of the disease. In addition, prevention of the disease with strict follow-up measures with sanitation and hygiene maintenance is also essential.

Background: Biologic medications, specifically the TNF-α inhibitors, have become increasingly prevalent in the treatment of chronic inflammatory disease (CID) in pregnancy. Objective: To determine pregnancy outcomes in women with CID exposed to biologics during pregnancy. Search strategy: PubMed and EMBASE databases were searched through January 1998-July 2021. Selection criteria: Peer reviewed, English language cohort, case-control, cross-sectional studies, and case series which contained original data. Data collection and analysis: Two authors independently conducted data extraction and assessed study quality. A meta-analysis of proportions using a random-effects model was used to pool outcomes. Linear regression analysis was used to compare the mean of proportions of outcomes across exposure groups using the ‘treated’ group as the reference category. All studies were evaluated using an appropriate quality assessment tool described by McDonald et al. Main Results: 35 studies, 11172 pregnancies, were eligible for inclusion. Analysis showed pooled proportions for congenital malformations: treated 4%(95% CI 0.03-0.4) vs disease matched 4%(0.03-0.05).Preterm delivery treated 12%(0.10-0.14) vs disease matched 10%(0.09-0.12) Severe neonatal infection: treated 5%(0.03-0.07) vs disease matched 5%(0.02-0.07) Low birth weight: treated 10%(0.07-0.12) vs disease matched 8%(0.07-0.09) The pooled Miscarriage: treated 13%(0.10-0.15) vs disease matched 8%(0.04-0.11) Pre-eclampsia; treated 1%(0.01-0.02) vs disease matched 1%(0.00-0.01). No statistical differences in proportions were observed. Conclusion: We demonstrated comparable pregnancy outcomes in pregnancies exposed to biologics, disease matched controls and CID free pregnancies. Overall, women receiving biologics in pregnancy may be reassured regarding their safety.

In a case of mechanical hemolytic anemia following surgical repair of type A aortic dissection, four-dimensional flow magnetic resonance imaging revealed highly elevated turbulent kinetic energy in a stenotic lesion of a replaced ascending aorta. Our findings suggest that turbulent kinetic energy evaluation enables the detection of the origin of mechanical hemolysis.

Xylem embolism resistance varies across species influencing drought tolerance, yet little is known about the determinants of the embolism resistance of an individual conduit. Here we conducted an experiment using the optical vulnerability method to test whether individual conduits have a specific water potential threshold for embolism formation and whether pre-existing embolism in neighbouring conduits alters this threshold. Observations were made on a diverse sample of angiosperm and conifer species through a cycle of dehydration, rehydration and subsequent dehydration to death. Upon rehydration after the formation of embolism, no refilling was observed. When little pre-existing embolism was present, xylem conduits had a conserved, individual, embolism resistance threshold that varied across the population of conduits. The consequence of a variable conduit-specific embolism threshold is that a small degree of pre-existing embolism in the xylem results in an apparently more resistant xylem in a subsequent dehydration, particularly in angiosperms with vessels. While our results suggest that pit membranes separating xylem conduits are critical for maintaining a conserved individual embolism threshold for given conduit when little pre-exisiting embolism is present, as the percentage of embolized conduits increases, gas movement, local pressure differences, and connectivity between conduits increasingly contribute to embolism spread.

Alternate shedding of vortices from the top and bottom of a conductor in a flow of wind causes Aeolian vibrations in overhead lines. Energy transfer to the conductors are calculated using the energy balance method. Simulation of wind power input into a harmonically oscillating cylinder by a turbulent flow is solved by numerical integration of the Naiver-Stokes equations using a numerical simulation tool. The results show that the assumption of lock-in phenomenon has oscillatory behaviour at lower amplitude to diameter (A/d) ratios for forced cylinder motion. Numerical results are in good agreement in the laminar case and k-ω SST turbulent case with measurements. The relationship between cylinder motion and vortex shedding is unsteady resulting in lower power transfer to the cylinder. The vortex shedding frequency oscillates with 10% turbulent intensity and length scales of 25 mm, 50 mm and 75 mm.

Abstract Objective. To evaluate the efficacy and safety of parallel loop binding suture of the lower uterus during cesarean section in pernicious placenta previa complicated with placenta increta. Design. A retrospective study Setting. Qilu Hospital of Shandong University Population. Patients with pernicious placenta previa between November 2014 and December 2020 at the Qilu Hospital of Shandong University were eligible. Methods. The degree of placental invasion was evaluated using preoperative color Doppler ultrasonography and/or magnetic resonance imaging (MRI). Main outcome measures. Postpartum hemorrhage was evaluated as the primary outcome. Additionally, neonatal outcomes were evaluated. Results. Of the 38 patients, only 3 (7.89%) underwent hysterectomy due to massive blood loss. With parallel loop binding compression suture, the volume of blood lost ranged from 500 - 6000 (mean: 2152.63±1169.37) mL and the volume of blood transfused was between 400 - 3200 (1431.58±699.85) mL. The mean gestational age was 36 weeks and 2 days (range: 32+6 to39+6 weeks). The average operation time was 109.78 ± 33.49 min, and the average fetal childbirth time was 14.05±5.60 min. The rate of NICU admission was 36.84% (14/38). The postoperative menstrual cycle and menstrual flow both returned to normal levels. All infants at our hospital were safely discharged after treatment. Conclusion. Parallel loop binding compression suture is an effective, swift, practical, and safe method to reduce postpartum bleeding in women with pernicious placenta previa, complicated with placenta increta.

Xylem is a main road in plant long-distance communication. Through xylem plants transport water, minerals and myriad of signaling molecules. With the onset during early embryogenesis, the development of xylem tissues relays on hormone gradients, activity of unique transcription factors, distribution of mobile miRNAs and receptor-ligand pathways. These regulatory mechanisms are often interconnected and all together contribute to the plasticity of water conducting tissue. Remarkably, root xylem carries water to all above-ground organs and therefore influences all aspects of plant growth. Because of the global warming and increasing water deficit, we need to come up with solutions for the crops of the future. It is clear that structure of water conducting elements directly impacts water transport within the plant. Among plant pathogens- vascular wilts attacking xylem -are the most harmful. Our knowledge about xylem anatomy and rewiring ability could bring the solutions against these diseases. In this review we summarize the recent findings on the molecular mechanisms of xylem formation with a special attention to the cellular changes, and cell wall rearrangements that are necessary to create functional capillaries. We emphasize the impact of abiotic factors and pathogens on xylem plasticity and discuss multidisciplinary approach to model xylem in crops.

Heme proteins play diverse and important biological roles, from electron transfer and chemical catalysis, to oxygen transport and/or storage. Although the distortion of heme porphyrin correlates with the physical properties of heme, such as the redox potential and oxygen affinity, the relationship between heme distortion and the heme protein environment is unclear. We here tested the hypothesis that the protein environment of the heme-binding pocket determines heme distortion (conformation). We analyzed the correlations between the amino acid composition of the heme-binding pocket and the magnitude of heme distortion along 12 vibrational modes by using machine learning. A correlation was detected in the three lowest-vibrational modes. Analysis of heme distortions in nearly the same environments of the heme-binding pocket supported this notion. Our analyses indicate that the heme-binding pocket environment is a major factor impacting the distortion of heme porphyrin along the three lowest-vibrational modes. In addition, statistical analysis of the distortion of heme porphyrin revealed that the peaks of distributions of the ruffling and breathing distortions are shifted from 0 (the equilibrium structure). Both the ruffling and breathing distortions are correlated with the redox potential of heme, so that heme molecules with these distortions have a lower redox potential than planar molecules. These findings explain the structure–function relationship of heme and can inform protein function engineering.

Introduction: Autism spectrum disorder, major depressive disorder, anxiety disorders, post-traumatic stress disorder, schizophrenia, insomnia, and disorders related to psychotropic substances are common diseases worldwide and in Colombia. The pharmacological treatments available for the management of mental disorders are effective, although adverse reactions sometimes limit their use; additionally, some patients do not have an adequate response to them, which generates the need to develop new effective and safe drugs. Methodology: A Delphi consensus was developed in real-time, with a panel of seven psychiatric specialists and a group of developer epidemiologists; a systematic search was carried out in 3 specialized databases and contributed articles. By the panel of experts participating in the consensus, two questionnaires were applied for consideration by the group of experts, anonymously and on an online platform with the Likert scale. Results: Recommendations were established based on the available evidence and the experience provided by the experts. Conclusions: There is biological plausibility in clinical and preclinical studies that suggest the effectiveness of the use of pure pharmaceutical-grade CBD, as adjunctive therapy, for the control of symptoms associated with mental disorders such as schizophrenia and disorders related to the abuse of psychotropic substances. However, more rigorous clinical trials are required to make more precise recommendations on CBD to treat other mental disorders. Additionally, pure pharmaceutical-grade CBD is considered a safe treatment.

Objectives The study was to apply deep learning (DL) with convolutional neural networks (CNNs) to laryngoscopic imaging for assisting in real-time automated segmentation and classification of vocal cord leukoplakia. Methods This was a single-center retrospective diagnostic study included 216 patients who underwent laryngoscope and pathological examination from October 1, 2018 through October 1, 2019. Lesions were classified as nonsurgical group (NSG) and surgical group (SG) according to pathology. All selected images of vocal cord leukoplakia were annotated independently by 2 expert endoscopists and divided into a training set, a validation set, and a test set in a ratio of 6:2:2 for training the model. Results Among the 260 lesions identified in 216 patients, 2220 images from narrow band imaging (NBI) and 2144 images from white light imaging (WLI) were selected. For segmentation, the average intersection-over-union (IoU) value exceeded 70%. For classification, the model was able to classify the surgical group (SG) by laryngoscope with a sensitivity of 0.93 and specificity of 0.94 in WLI, and a sensitivity of 0.99 and specificity of 0.97 in NBI. Moreover, this model achieved a mean average precision (mAP) of 0.81 in WLI and 0.92 in NBI with an IoU> 0.5. Conclusions The study found that a model developed by applying DL with CNNs to laryngoscopic imaging results in high sensitivity, specificity, and mAP for automated segmentation and classification of vocal cord leukoplakia. This finding shows promise for the application of DL with CNNs in assisting in accurate diagnosis of vocal cord leukoplakia from WLI and NBI.

Theory predicts that sexual selection should aid adaptation to novel environments, but empirical support for this idea is limited. Pathogens are a major driver of host evolution and, unlike abiotic selection pressures, undergo epidemiological and co-evolutionary cycles with the host involving adaptation and counteradaptation. Because of this, populations harbor ample genetic variation underlying immunity and the opportunity for sexual selection based on condition-dependent “good genes” is expected to be large. In this study, we evolved populations of Drosophila melanogaster in a 2-way factorial design manipulating sexual selection and pathogen presence, using a gram-negative insect pathogen Pseudomonas entomophila, for 14 generations. We then examined how the presence of sexual selection and the pathogen, as well as any potential interaction, affected the evolution of pathogen resistance. We found increased resistance to P. entomophila in populations that evolved under pathogen pressure, driven primarily by increased female survival after infection despite selection for resistance acting only on males over the course of experimental evolution. This result suggests that the genetic basis of resistance is in part shared between the sexes. We did not find any evidence of sexual selection aiding adaptation to pathogen, however, a finding contrary to the predictions of “good genes” theory. Our results therefore provide no support for a role for sexual selection in the evolution of immunity in this experimental system.
