The metabolism of xenobiotic can be elaborated as breakdown of gulped exterior specks. Subsequently acclimatization of exogenous particles by means of host cells, liver Plays its part as the principal location of biotransformation. Anatomical, morphological as well as physiological features of liver create its specific characteristics of acting as a metabolic site of body. The DMEs (Drug-metabolizing enzymes) are the type of enzymes which are useful for biotransformation of a number of drugs and other xenobiotics. These enzymes are consists of a group of proteins which can leads to metabolism of drugs as well as a immense assortment of compounds termed as xenobiotics encompassing those as ecological toxins as well as endogenous amalgams as the steroids as well as some prostaglandins. For the sake of decontamination of several extraneous besides endogenous compounds, the DMEs in addition to transporters play indispensable task. Introduction:

Some points in the article caught our attention. Inherited bleeding disorders need pre-planning in the preoperative and operative period of cardiac surgery (2). Were the bleeding disorders questioned, while taking the anamnesis of the included patients?Atrial fibrillation is one of the most common complications after coronary artery bypass surgery (3). Anticoagulant therapy is inevitable in patients with atrial fibrillation. Patients with anticoagulation therapy due to atrial fibrillation or any other cause is not mentioned in the text which may be associated with postoperative bleeding.And finally, when the current literature is reviewed, it is seen that the use of peroperative tranexamic acid has a reducing effect on bleeding after coronary bypass surgery. (4). In this study, did the authors use tranexamic acid? We congratulate the authors about their manuscript. We look forward to hear the authors’ opinions on these matters.Bastopcu M, Özhan A, Erdoğan SB, Kehlibar T.

The intestinal microbiota play an important role in the life of amphibians. The composition of the intestinal microbial community may vary by developmental stage. In this study, 16S rRNA high-throughput sequencing was used to study the intestinal microbiota of Hynobius maoershanensis tadpoles and adults that exclusively inhabit the Maoer Mountain swamp at an altitude of approximately 2000 m. The results indicated that there was no significant difference in intestinal microbiota between tadpoles and adults. Nevertheless, the abundance of intestinal microbiota in adults was much higher than that in tadpoles. Specifically, at the phylum level, Bacteroidetes was more abundant in adults than in tadpoles. At the genus level, Proteobacteria, Actinobacteria, Cyanobacteria, and Planctomycetes were more abundant in tadpoles, whereas Burkholderiaceae, Caedibacter, Bacteroides, and Serratia were more abundant in adults. A functional prediction analysis revealed that there was no significant difference between tadpoles and adults; however, the function of the intestinal microbiota in H. maoershanensis includes amino acid transport and metabolism, general function prediction only, transcription, energy production and conversion, liquid transport, and metabolism. The aquatic and terrestrial living environment of tadpoles and adults may be the main reason for the difference in intestinal microbiota between tadpoles and adults. Our study provides evidence of variations in the intestinal microbiota of tadpoles and adult amphibians, highlighting the influence of historical developments on the intestinal microbiota and the need for increased understanding of the importance of physiological characteristics in shaping intestinal microbiota of amphibians, which consequently help us to understand the adaptative mechanism of amphibians from an aquatic to a terrestrial environment.

Since African swine fever (ASF) was first reported in 1921, it has brought huge economic losses to the world pig industry. No vaccine or therapy is available. Rapid and effective diagnostics are key steps in managing ASF. We generated three monoclonal antibodies (mAbs) against the African swine fever virus (ASFV) phosphoprotein p30 and designated these as 7D2, 8C8 and 2F6. Epitope mapping revealed that mAb 7D2 recognized 26VFHAG SLYNW 35 of p30, and mAb 8C8 and 2F6 recognized 1MDFIL NISMK MEVIF KTDLR 20 of p30. Furthermore, epitope 1MDFIL NISMK MEVIF KTDLR 20 and 26VFHAG SLYNW 35 could be well recognized by ASFV-positive sera from natural infected pigs, suggesting that they were natural linear B-cell epitope. Conservation analysis indicated that epitope 1MDFIL NISMK MEVIF KTDLR 20 and 26VFHAG SLYNW 35 were highly conserved among the different strains of ASFV. This is the first research to characterize specific mAbs against p30 protein. These findings may facilitate further understanding the function of p30 protein and development of diagnostic tools.

In this study, complete mitochondrial genomes of nine species representing three tribes in the subfamily Pyrginae sensu lato were newly sequenced. The mitogenomes are closed double-stranded circular molecules, with the length ranging from 15,232 bp to 15,559 bp, which all encode 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and a control region. The orientation and gene order of these nine mitogenomes are identical to the inferred ancestral arrangement of insects. All PCGs exhibit the typical start codon ATN except for cox1 (using CGA) and cox2 (using TTG) in Mooreana trichoneura. Most of the PCGs terminate with a TAA stop codon, while cox1, cox2, nad4, and nad5 end with the incomplete codon single T. For the different datasets, we found that the one comprising all 37 genes of mitogenome produced the highest nodal support, indicating that the inclusion of RNAs improves the phylogenetic signal. This study re-confirmed the status of Capila, Pseudocoladenia and Sarangesa, namely Capila belongs to the tribe Tagiadini, and Pseudocoladenia and Sarangesa to the tribe Celaenorrhini. Diagnostic characters distinguishing the two tribes, the length of the forewing cell and labial palpi, are no longer significant. Two population of Pseudocoladenia dan fabia from China and Myanmar and P. dan dhyana from Thailand are confirmed conspecific.

To the EditorAsthma is characterized by recurrent airflow limitation with airway hyperresponsiveness (AHR) due to chronic inflammation.1 Various types of cells, cytokines, chemokines and mediators are involved in the pathogenesis of asthma.2 The mechanisms underlying AHR have attracted considerable attention in recent decades. AHR reportedly did not develop in several asthma models, e.g., mice lacking certain cell types—such as mast cells or eosinophils—or not expressing certain genes, such as for type 2 cytokines or FcεRI. However, T2 inflammation itself is also impaired in some of these genetically-engineered mice. In addition, these models do not completely recapitulate human asthma. Therefore, the specific molecular pathway(s) regulating human AHR remains unknown.3In humans, mechanisms of AHR have been partially identified in ex vivo models using lung, trachea, or bronchi,4,5 but the in vivo mechanisms remain unclear. Recently, biologics have been approved for steroid-refractory asthma and provide strong evidence of roles for certain molecular pathways in the pathogenesis of asthma.6,7 For example, an anti-IgE monoclonal antibody (omalizumab) did not alleviate AHR even after the symptoms were significantly reduced.8 However, no studies have investigated AHR after treatment with anti-IL-5, anti-IL-5R, or anti-IL-4Rα antibodies.Here, we describe our experience using dupilumab, an anti-IL-4Rα antibody, to treat a 12-year-old boy with refractory atopic asthma.An 8-year-old boy who had suffered from bronchial asthma since he was 3 years old was admitted to a tertiary-care hospital, Yawatahama City General Hospital, due to a severe asthma exacerbation in May 2016. Following discharge, he visited the allergy unit of the hospital. He was treated with an oral leukotriene receptor antagonist, a β2 agonist and slow-release theophylline (SRT), as well as with inhaled high-dose corticosteroid and a long-acting β2 agonist. However, his asthma symptoms did not fully resolve. In Spring of 2019, he developed pertussis, with repeated chronic coughing and wheezing episodes, and his respiratory function subsequently worsened. He became unable to exercise normally at school due to exercise-induced bronchoconstriction. In September 2019, he was subcutaneously injected with 600 mg of dupilumab, followed by 300 mg every 2 weeks.AHR, respiratory function, serum total and specific IgE levels, and peripheral eosinophil counts were evaluated before and at 4 and 6 months after starting dupilumab. AHR was assessed by the standard acetylcholine inhalation test (AcIT) in accordance with the guideline of the Japanese Society of Allergology. That is, he inhaled acetylcholine chloride solutions diluted with saline from low to high concentrations (0, 39, 78, 156, 313, 625, 1250, 2500, 5000, 10000, 20000 µg/mL) for two minutes, followed by a pulmonary function test; this was repeated until there was a 20% decline in his forced expiratory volume in one second (FEV1). The last concentration of inhaled solution was defined as the threshold of the AcIT, and the cut-off concentration between asthma patients and normal subjects was 10000 µg/ml. All medications except SRT were stopped 48 hours before the AcIT, and SRT was stopped 18 hours before the AcIT.His subjective symptoms gradually improved during the first 4 months of dupilumab treatment. Surprisingly, his AHR induced by acetylcholine inhalation completely disappeared at that point, and that status continued for two months. SRT and other oral and inhaled bronchodilators were discontinued 7 months after dupilumab was started. Since then, he has experienced no asthma symptoms, such as cough, wheeze or dyspnea, even after daily exercise, although his respiratory function has not yet fully recovered.Table 1 shows the following data that were determined before and at 4 and 6 months after starting dupilumab: respiratory function data, serum theophylline level, AcIT threshold concentration, serum total IgE level,Dermatophagoides pteronyssinus -specific IgE level, and peripheral eosinophil count. After starting dupilumab, the AcIT threshold concentration increased dramatically, from 313 to over 20000 µg/mL, and the total and specific IgE levels decreased, but the peripheral eosinophil count decreased only by half.We administered dupilumab, an anti-IL-4Rα antibody, to a 12-year-old boy with severe atopic asthma, and his asthmatic symptoms disappeared, with drastic improvement of AHR. His total and specific IgE levels decreased markedly, but his peripheral eosinophil count decreased only by half. On the other hand, an earlier study found that omalizumab, an anti-IgE biologic, improved the clinical symptoms and decreased the peripheral eosinophil count, but AHR remained unchanged.8 Taken together, those findings imply that blockade of IL-4 and IL-13 is involved in the causation of AHR.IL-4 and IL-13, but not IL-5 or IL-17A, were reported to induce hyperresponsiveness to histamine by enhancing expression of histamine H1 receptor and cysteinyl leukotriene receptor 1 in isolated human small airway tissue.5 On the other hand, dupilumab treatment abrogated those effects of IL-4 and IL-13.5 The clinical course of our case is in good agreement with those earlier findings.This report has a limitation, since it reports a single case. Nevertheless, we believe that this is the first study showing that dupilumab therapy directly improved AHR in an atopic asthma patient. In the present patient, the peripheral eosinophil count after dupilumab treatment decreased only by half. That is presumably because IL-5, the critical cytokine for eosinophil development, activation and survival, was not inhibited by dupilumab. The dupilumab treatment also reduced his asthma symptoms and improved his quality of life, although his respiratory function, especially the maximal mid-expiratory flow, was not normalized, presumably due to the presence of airway remodeling. We expect that his respiratory function will improve later, and further observation and assessment are thus needed.In conclusion, IL-4R signaling is likely involved in development of AHR in atopic asthma patients.

Low disease activity, no angioedema, and no treatment before pregnancy were risk factors for worsening during pregnancy (1).We hypothesized that patients with chronic spontaneous urticaria (CSU) that worsens during pregnancy are more likely to have type I autoimmune CSU, also called autoallergic CSU. We also hypothesized that patients who improve during pregnancy are more likely to have type IIb autoimmune CSU (2). This hypothesis is supported by the immunological changes observed during pregnancy, i.e., decreased Th1 and Th17 immunity and a switch to a Th2-type cytokine profile (3).To test this hypothesis, we retrieved total IgE levels of CSU patients who gave consent to be included in the PREG-CU study (1). Elevated IgE levels have been reported to be linked to autoallergic CSU, whereas low IgE is a marker of type IIb autoimmune CSU (4).Total IgE blood levels were available for 115 of the 218 CSU patients not treated with omalizumab enrolled in PREG-CU. The median IgE level was 106 (range: 3-1664 IU/mL), more than half of patients (51.3%) had elevated IgE (≥100 IU/mL), and 17.4% had low IgE (<40 IU/mL). Most patients with mild disease (51%) or moderate disease (61%), but only one in four patients with severe disease (26%) had elevated IgE levels (≥100 IU/mL). IgE levels were lower in patients with severe disease (68 IU/mL) vs mild (112 IU/mL; p=0.009) or moderate disease (128 IU/mL; p=0.018), and low IgE levels (<40 IU/mL) were more frequent in patients with severe than mild disease (36.8 vs 11.6%; p=0.034).CSU patients who got worse during pregnancy had higher IgE levels (154 vs. 82.2 IU/mL; p=0.033) and numerically higher rates of elevated IgE (57.5 vs. 46%) compared to patients who got better during pregnancy. In contrast, patients who improved during pregnancy more often had low IgE levels than patients who deteriorated (22 vs. 12.5%), but this was not statistically significant. One in three of our patients (34.9%) had elevated anti-TPO, another marker of type IIb autoimmune CSU, but this was not linked to improvement during pregnancy.Worsening of CSU during pregnancy in patients with high IgE levels may be explained, in part, by the role that IgE and Th2 immunity play in the pathogenesis of their CSU. High IgE, in CSU, has been linked, in some studies, to autoallergy, characterized by the presence of IgE autoantibodies (5). Pregnancy skews immunity towards Th2 responses and patients with Th2-driven diseases, including allergies, often experience worsening of their disease during pregnancy (3). Improvement of CSU during pregnancy in patients with low IgE may point to a role of Th1 and Th17 cytokines in the pathogenesis of their disease. Low IgE is a type IIb autoimmune CSU marker, which is linked to Th1 and Th17 autoimmunity (6). Pregnancy decreases Th1/Th17 immunity, and patients with TH1/TH17-driven autoimmune diseases often experience improvement during pregnancy (3). Our finding that elevated IgG-anti-TPO, another marker of type IIb autoimmune CSU, is not linked to CSU improvement during pregnancy remains unexplained. Many CSU patients with IgG-anti-TPO also have IgE-anti-TPO and vice versa, which could point to both autoallergic and autoimmune drivers of their CSU. Better biomarkers are needed to identify which patients have autoallergic CSU, autoimmune CSU, both or none of these.Our findings support the notion that CSU is a heterogeneous disease, with at least two endotypes, i.e., autoallergic and autoimmune. Further studies are needed to better characterize the course of disease during and after pregnancy, in patients with autoallergic CSU and with autoimmune CSU. IgE levels may help to predict which CSU patients get worse and which improve when they get pregnant.

Aim: The association between COVID-19 disease severity and certain medicines for the treatment of chronic diseases is currently under discussion. We herein evaluated if previous exposure to antihypertensive, hypoglycaemic, and lipid-lowering drugs increases the risk of poorer COVID-19 outcomes. Methods: We performed a retrospective study on three cohorts of COVID-19 adult patients between March 2020 and May 2020 at the Vall d’Hebron University Hospital. Information relating to the patient lifestyle, comorbidities, and chronic exposures was retrieved from primary healthcare electronic records. Three cohorts were examined, namely patients who had died or required intensive care treatment (ICU/Death [ICU-D] Cohort), patients who required hospitalisation (Hospitalisation [HOSP] Cohort), and patients who only attended the emergency department (Emergencies [EM] Cohort). Descriptive statistics and a multivariate logistic regression model were used to investigate associations with drug exposure, where EM was employed as the reference cohort. Results: We included 1,778 patients: 417 (23.5%) from the ICU-D Cohort, 1,052 (59.2%) from the HOSP Cohort, and 309 (17.4%) from the EM Cohort. After multiple imputations and data adjustment by potential confounders, no statistically significant association was observed between the COVID-19 severity and the use of antihypertensives, hypoglycaemic agents, or lipid-lowering agents, with the exception of calcium channel blockers (CCB) (ICU-D Cohort: OR 2.23; CI 95% [1.03–4.83]; P = 0.042). Conclusions: Most results on lifestyle characteristics and comorbidities related to COVID-19 severity were in agreement with current knowledge, although some associated factors are nowadays a matter of controversy and further investigation is required.

Vaccines have reduced the transmission and severity of COVID-19 but there remains a paucity of efficacious treatment for drug resistant strains and more susceptible individuals. Repurposing existing drugs is a timely, safe and scientifically robust method for treating pandemics such as COVID-19. Here, we review the pharmacology and scientific rationale for repurposing niclosamide, an anti-helminth already in human use as a treatment for COVID-19. In addition to potent antiviral activity, niclosamide has shown pleiotropic anti-inflammatory, antibacterial, bronchodilatory and anticancer effects in numerous pre-clinical and early clinical studies. The advantages and rationale for nebulised and intranasal formulations of niclosamide, which target the site of primary infection in COVID-19, are reviewed. Finally, we discuss the TACTIC-E clinical trial, an international COVID-19 therapeutic platform trial for the use of licensed and novel therapeutic agents, which is investigating niclosamide as a promising candidate against SARS-CoV-2.

The extraction of oil by a new aqueous method has been promoted because it is environmentally friendly, safe and economical of cost. A new aqueous method using 1.4:10.0 water-to-pecan kernel slurry ratio was developed, which recovered 97.73% of oils from the kernel containing 70.47% crude oil content. The method had a higher oil recovery as compared to enzyme-assisted extraction or solvent extraction or cold pressing in terms of producing oil for safe consumption. The method recovered oils with 0.47 mg KOH/g acid value and 0.34 mmol/kg peroxide value which were identical to that obtained by enzyme-assisted aqueous method and lower than that obtained by solvent extraction. The de-oiled pecan meal obtained by the new aqueous method only contained 5.14% residual oils, which was edible since no harmful chemical was added during oil extraction. No waste water was produced during the aqueous extraction of oils.

1. Omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) are key structural lipids and their dietary intake is essential for brain development of virtually all vertebrates. The importance of n-3 LC-PUFA has been demonstrated in clinical and laboratory studies, but little is known about how differences in availability of n-3 LC-PUFA in natural prey influence brain development of wild consumers. The availability of n-3 LC-PUFA in the prey communities is driven by primary producers and it is therefore distributed heterogeneously, but predictably across ecosystems, being higher in aquatic than in terrestrial food webs. Consequently, the numerous consumers foraging on the interface of aquatic and terrestrial food webs can differ substantially in their intake of n-3 LC-PUFA, which may lead to in brain development, yet, this hypothesis still remains to be tested.2. Here we use the previously demonstrated shift towards higher reliance on n-3 LC-PUFA deprived terrestrial prey of native brown troutSalmo trutta living in sympatry with invasive brook troutSalvelinus fontinalis to explore this hypothesis.3. We found that the content of n-3 LC-PUFA in muscle tissues of brown trout decreased with increasing consumption of n-3 LC-PUFA deprived terrestrial prey. Brain volume was positively related to content of the n-3 LC-PUFA, docosahexaenoic acid, in muscle tissues of brown trout.4. Our study thus suggests that increased reliance on low quality diet of n-3 LC-PUFA deprived subsidies from terrestrial food web can have a significant negative impact on brain development of wild trout. These findings provide the first evidence of an intra-specific link between n-3 LC-PUFA content in natural prey and brain size of wild vertebrate consumers.5. Ongoing global change is predicted to reduce the availability of dietary n-3 LC-PUFA across food webs. Therefore, our findings emphasise the need for further research on how wild consumers adapt to the shortage of dietary n-3 LC-PUFA in order to maintain optimal development and functioning of their brain, which is crucial for their fitness.

Circadian clocks manifest adaptations to predictable 24-h fluctuations in the exogenous environment, but it has yet to be determined why the endogenous circadian period length in the wild varies genetically around the hypothesized optimum of 24 h. We quantified genetic variation in circadian period in leaf movement in 30 natural populations of the Arabidopsis relative Boechera stricta sampled within only 1° of latitude but across an elevational gradient spanning 2460−3300 m in the Rocky Mountains. Measuring over 3800 plants from 473 maternal families (7−20 per population), we found genetic variation that was of similar magnitude among vs. within populations, with population means varying between 21.9−24.9 h and maternal family means within populations varying by up to ~6 h. After statistically factoring out spatial autocorrelation at the habitat extremes, we found that elevation explained a significant proportion of genetic variation in circadian period such that higher-elevation populations had shorter mean period lengths and less within-population variation. Environmental data indicate that these spatial trends could be related to steep regional climatic gradients in temperature, precipitation, and their intra-annual variability. Our findings provide evidence that spatially fine-grained environmental heterogeneity contributes to naturally occurring genetic diversity in circadian traits in wild populations.

A history of recurrent benign mucous membrane pemphigoid episodes had plagued patients. Major treatments include immunosuppressant or systemic glucocorticoid drugs, but all of them have side effects. Therefore, we tried to find a way to minimize side effects by using traditional Chinese medicine, and speeding up the healing process.

Periodontal Ehlers-Danlos syndrome type VIII (pEDS) is rare and caused by mutation in complement 1 subunit. Lack of attached gingiva, pretibial plaques, joint mobility, skin fragility, and easy bruising consolidate the diagnosis. We describe a case of de novo-mutation of pEDS with generalized periapical cemento dysplasia (PCD) and leukoencephalopathy.

The clinical and radiographic dilemma of fibrous dysplasia versus osteomyelitis is highlighted in this case of a 4-year-old girl with a bony hard swelling over in mandiblular body and ramus. Differences between histopathological appearance and radiographic presentation with the possible differential diagnosis were discussed and compared with previous studies.

Prey evolve anti-predator strategies against multiple enemies in nature. We examined how a prey species adopts different predation avoidance tactics against pursuit or sit-and-wait predators. As prey, we used two strains of Tribolium beetles artificially selected for short or long duration of death feigning. The results showed that, as prey, the short strains displayed the same behavior, escaping, against the two types of predators. On the other hand, death feigning is known to be effective for evading a jumping spider in the case of the long strains, while the present study showed that the long strain beetles used freezing behavior against a sit-and-wait type predator A. venator in this study. The short strain beetles were more easily orientated by predators and suffered a higher rate of predation than the long strains. The time to predation was also shorter in the short strains compared to the long strains. When the predator was starved, even the long strains were preyed upon when the predator was orientated toward the prey, suggesting the starvation period, i.e., prey density, is an important factor for antipredator behavior. Traditionally, death feigning has been thought to be the last resort in a series of anti-predator avoidance behaviors. However, our results showed that freezing and death feigning were not parts of a series of behavior, but independent behaviors against different predators, at least for these beetles. The results also suggest that the differences in feeding rates between the strains could be explained by differences in activity among the strains.

L’incremento delle emissioni odorigene nell’ambiente ha portato ad un urgente necessità di ricerca e sviluppo di nuove tecnologie per il loro trattamento. L’attività sperimentale si è focalizzata sull’innovativo sistema OTAER, capace di trattare composti odorigeni ed al contempo produrre biomassa valorizzabile. L’attività ha previsto la verifica delle performance in diverse condizioni operative e l’analisi dell’influenza di due differenti tipi di nutrienti sulle potenzialità di recupero della biomassa. Nello specifico sono stati utilizzati due differenti tipi di reflui nell’ottica di un’economia circolare, un refluo urbano ed un refluo caseario.I risultati ottenuti hanno dimostrato che il sistema ha un’elevata efficacia di rimozione dei composti odorigeni, indipendentemente dal tipo di refluo utilizzato. L’impiego del refluo caseario ha permesso di ottimizzare la produttività volumetrica di biomassa e di lipidi, ottenendo così una potenziale produzione maggiore di biodiesel.

Figure S1. Detailed explanation of microfabrication step of fully integrated NIR-LFC. a) The wafer-level microfabrication of iMLA-AFF involves a thin Cr lift-off, and plasma enhanced chemical vapor deposition (PECVD) of SiO2, and a thick Cr lift-off (6 nm Cr – 135 nm SiO2 – 130 nm Cr), photolithographic patterning of DNR photoresist (DNR L300-D1, Dong-jin Semichem, Co., Ltd, Korea), and thermal reflow. Note that a DNR photoresist exhibits both UV curable (Negative photoresist) and thermoplastic characteristic, suitable for metal lift-off as well as microlens formation. The hydrophobic coating of fluorocarbon (C4F8) effectively prevents the lateral expansion of microlenses on a metal surface during thermal reflow. iMLA-AFF are inversely bonded to an image sensor with a 60 μm gap spacer and packaged to a compact objective lens by using a UV curable adhesive. The NIR-LFC is fully assembled by combining a 8.5 mm × 4.7 mm printed circuit board with two VCSEL sources and VCSEL housing. b) A scanning electron microscope (SEM) of hexagonally arranged iMLA-AFF with 30 μm in microlens diameter and 3 μm in microlens gap. c) A photograph of fully packaged NIR-LFC. The camera module is connected to flexible extension cable and delivers raw image to Raspberry Pi 4(B). The total physical dimension of camera module is 8.5 mm × 14.0 mm × 5.6 mm.

To provide the most comprehensive picture of species phylogeny and phylogeography of European roe deer (Capreolus capreolus), we analysed mtDNA control region (610 bp) of 1469 samples of roe deer from Central and Eastern Europe and included into the analyses additional 1541 mtDNA sequences from GenBank from other regions of the continent. We detected two mtDNA lineages of the species: European and Siberian one (an introgression of C. pygargus mtDNA into C. capreolus). The Siberian lineage was most frequent in eastern part of the continent and declined towards Central Europe. The European lineage contained three clades (Central, Eastern and Western) composed of 2 to 8 subclades, many of which were separated in space. The Western clade appeared to have a discontinuous range from Portugal to Russia. Most of the subclades in the Central and the Eastern clades were under expansion during the Weichselian glacial period before the Last Glacial Maximum (LGM), while the expansion time of the Western clade overlapped with the Eemian interglacial. High genetic diversity of extant roe deer is the result of their survival during the LGM in a large, contiguous range spanning from the Iberian Peninsula to the Caucasus Mts. and in two northern refugia.

The climate of the Eurasia inland basin (EIB) is characterized by limited precipitation and high potential evapotranspiration; as such, water storage in the EIB is vulnerable to global warming and human activities. There is increasing evidence pointing to varying trends in water storage across different regions; however, a consistent conclusion on the main attributes of these trends is lacking. Based on the hydrological budget in a closed inland basin, the main attributes of changes in actual evapotranspiration (AET) and terrestrial water storage (TWS) were identified for the EIB and each closed basin. In the EIB and most of its closed basins, the TWS and AET showed significantly decreasing and non-significantly increasing trends, respectively. The primary cause underpinning the significantly decreasing TWS in the EIB was increasing AET. Approximately 70% of the increase in AET has been supplied by increased irrigation diversions and glacial melt runoff. At the basin scale, similar to the EIB, changes in AET were the predominant factor driving changes in TWS in most basins; the exception to this was the Balkhash Lake basin (BLB), Iran inland river basin (IIRB), Qaidam basin (QB), and Turgay River basin (TuRB). In these basins, changes in precipitation largely contributed to the TWS changes. The AET consumption of other water resources was the main factor contributing to AET changes in seven of 16 basins, including the Aral Sea, Caspian Sea, Junggar, Monglia Plateau, Qiangtang Plateau, and Tarim River basins. The increase in precipitation contributed more than 60% of increasing AET in four of 16 basins, particularly in the Helmand River basin and QB (>90%). Changes in precipitation and consumption by other water supply sources contributed to approximately half of the AET changes in the other five basins, including the Inner Mongolia Plateau, Issyk-Kul Sarysu, BLB, IIRB, and TuRB basins.

Background: COVID-19 outbreak lead to nationwide lockdown on the March 16th, 2020 in Turkey. We aimed to quantitively determine the change in frequency of upper and lower respiratory tract infections and asthma in pediatric population associated with COVID-19. Methods: The electronic medical record data of pediatric population admitted to the emergency department (ED), outpatient and inpatient clinics and pediatric intensive care unit (PICU) were analyzed with the diagnosis of Influenza, upper and lower respiratory tract infections (URTI, LRTI) acute bronchiolitis and asthma. The data of the first year of the pandemic was compared with the previous year. Results: In total 112496 admissions were made between April 1, 2019 and March 31, 2021 in our hospital. A decline was observed in ED admissions (-73%) and outpatient clinic (-70%) visits, hospitalizations (-41.5%) and PICU admissions (-42%). The admissions with the diagnosis of Influenza and URTI had a decline from 4.26% to 0.37% (p=0.0001), and from 81.54% to 75.62% (p=0.0001), respectively. An increase was observed in the LRTI, acute bronchiolitis and asthma (from 8.22% to 10.01% (p=0.0001), from 2.76% to 3.07% (p=0.027) and from 5.96% to 14% (p=0.0001), respectively). Conclusions: A dramatic decrease was observed in the number of admissions to ED and inpatient clinics and outpatient clinic visits and PICU admissions, and, when the rates of admissions were compared, the general rate of admissions to ED showed a decrease while inpatient, outpatient clinics and PICU admissions demonstrated an increase during the pandemic.

Malignant transformation of mature cystic teratoma (MCTO) is a rare entity. Even rarer is the transformation of MCTO into undifferentiated carcinoma. We report a case of an 80-year-old woman with undifferentiated carcinoma and squamous cell carcinoma component originating from mature cystic teratoma of the ovary.

FIGURE 5[*: Coronary artery pseudoaneurysm sac, Arrow:Coronary artery side of the fistula(Closed)]DiscussionCoronary artery pseudoaneurysms are mostly seen after catheter intervention in the coronary arteries. Pseudoaneurysm develops after traumatic dissection or perforation of the coronary arteries. It may develop due to the use of an ’oversized’ balloon or stent, or atherectomy. (4) Most pseudoaneurysms developing after stenting are asymptomatic and are not discovered until the next coronary angiography. (2) Other etiologies are infection, after trauma or pregnancy.(1)However, no previous coronary artery intervention was performed in our patient. There is no history of trauma in the distant or recent period. Inflammatory conditions (Kawasaki disease, Takayasu’s arteritis, Lupus erythematosus or polyarteritis nodosa, Behçet’s disease) were investigated during hospitalization, and the results were negative. In the pathology report Monckeberg’s sclerosis was revealed. It is not known whether this finding explaining the etiology of pseudoaneurysm.Pseudoaneurysms of coronary arteries has been mentioned in some coronary angiography series, but it is controversial whether aneurysms are true or pseudoaneurysms. (2)The incidence of coronary artery aneurysms has been reported between 0.3% and 5% in different reports. Although by definition their size is larger than 50% of the luminal diameter, the definition of gigantic aneurysm is not fully classified. In various sources, 2cm, 4cm, and 5cm limits have been suggested for coronary artery diameters, but they have not been universally accepted. In the literature, the prevalence of the number of reported cases with a coronary artery diameter of 5 cm or more is 0.02%.(5)Although coronary artery pseudoaneurysms are mostly silent, they can lead to fatal situations. Rarely, distal embolization due to dissection of the vessel wall and the development of myocardial infarction or angina pectoris may occur, but in case of rupture, life-threatening cardiogenic shock and/or cardiac tamponade may be encountered. (2) In our patient, a high-output flow occurred due to a giant coronary artery pseudoaneurysm that fistulized into the left atrium, and coronary artery perfusion was impaired. The ventricular walls of the heart are thinned and the ejection fraction is decreased.The natural history, when to treat, and outcome of spontaneous coronary artery pseudoaneurysms are controversial. Surgical indication for incidentally detected pseudoaneurysms has not been clearly defined. Although surgical intervention is an option in case of pseudoaneurysm enlargement or ischemia in the follow-up, a treatment plan can also be made with stent intervention.(6)The surgical treatment method is mostly coronary artery bypass and coronary revascularization. Spontaneous regressing pseudoaneurysms are mentioned in the literature. (7) Since there is no standard approach in spontaneous coronary artery pseudoaneurysms, a patient-specific decision should be made. In our patient, revascularization was not performed due to adequate evaluation of intraoperative coronary artery flow after pseudoaneurysm repair.In this case, we have brought a new perspective on the fact that coronary pseudoaneurysm, which is a rare case, can fistulize and lead to a cardiomyopathy-like picture and that this condition can be treated without the need for revascularization.All data analysed during this study are included in this published article.ConclusionSpontaneous giant coronary artery pseudoaneurysm is a rare condition.Monckeberg’s sclerosis may be the etiology of this rare condition. Because of the risk of rupture and myocardial infarction, surgical treatment is required to establish adequate coronary artery flow.Funding: NoneConflict of Interest: NoneAUTHOR CONTRIBUTIONSConcept/design: Alp Yıldırım, Bekir Boğaçhan AkkayaDrafting:Alp YıldırımCritical revision of the article:Levent Mavioğlu,Mehmet Ali ÖzatikReferences1.
