Aim: Species’ environmental requirements and large-scale spatial and evolutionary processes are known to determine the structure and composition of local communities. However, ecological interactions and historical processes also have major effects on community assembly at landscape and local scales. In this work we evaluate whether two xerophytic shrub communities follow fixed ecological assembly dynamics throughout large geographical extents, or their composition is rather driven by species individualistic responses to environmental and macroecological constraints. Location: SW Iberian Peninsula (Portugal and Spain) Taxa: Stauracanthus genistoides agg. and Ulex australis agg (Fabaceae). Methods:Inland dune xerophytic shrub communities were sampled in 95 plots distributed within their potential area of occurrence. Then, we described the main gradients of vegetation composition and assess the relevance of biotic interactions. We also characterized the habitat suitability of the dominant species, S. genistoides and U. australis, to map the potential distribution of the xerophytic shrub communities. Finally, to identify the relative importance of each factor driving changes in community composition, we examined the relationships between the vegetation gradients and a broad set of explanatory variables. Results: Our results show that xerophytic shrubs follow uniform successional patterns throughout the whole geographical area, but also that these communities respond differently to the main environmental gradients in each region. Soil organic matter is the main determinant of community variations in the northern regions, Setúbal Peninsula and Comporta, while in the South/South-Western region most of the variation between both types of communities is explained by temperature seasonality. Main conclusions: The relative importance of the main factors causing community-level responses varies according to regional processes and the suitability of the environmental conditions for the dominant species in these communities. These responses are also determined by intrinsic community mechanisms that result in a high degree of similarity in the gradient-driven community stages in different regions.

Whole-genome sequencing for generating SNP data is increasingly used in population genetic studies. However, obtaining genomes for massive numbers of samples is still not within the budgets of many researchers. It is thus imperative to select an appropriate reference genome and sequencing coverage to ensure the accuracy of the results for a specific research question, while balancing cost and feasibility. To evaluate the effect of the choice of the reference genome and sequencing coverage on downstream analyses, we used five confamilial reference genomes of variable relatedness and three levels of sequencing coverage (3.5x, 7.5x and 12x) in a population genomic study on two caddisfly species: Himalopsyche digitata and H. tibetana. Using these 30 datasets (five reference genomes × three coverages × two target species), we estimated population genetic indices (inbreeding coefficient, nucleotide diversity, pairwise and genome-wide FST) based on variants and population structure (PCA and admixture) based on genotype likelihood estimates. The results showed that both distantly related reference genomes and lower sequencing coverage lead to degradation of resolution. In addition, choosing a more closely related reference genome may significantly remedy the defects caused by low coverage. Therefore, we conclude that population genetic studies would benefit from closely related reference genomes, especially as the costs of obtaining a high-quality reference genome continue to decrease. However, to determine a cost-efficient strategy for a specific population genomic study, a trade-off between reference genome relatedness and sequencing depth can be considered.

Nanotechnology deals with the study and manipulation of materials on an atomic or a molecular scale almost less than 100 nm. Nanotechnology encompasses the synthesis and applications of biological, chemical and physical systems which ranges from individual atom to molecular or submicron level. It is the more interesting field for the scientists due to various applications in different fields of science e.g., biomedical engineering, material science, medicine and electronics at nanoscale level. The particles ranges from 1 to 100 nm by a surrounded interfacial layer are basically called nanoparticles. Ag nanoparticles are the most fascinating and vital nanoparticles amongst the other metallic nanoparticles like gold, tin, palladium etc. In this review literature, the synthesis and properties of Ag nanoparticles have been discussed. Herein, main area of study interest is to find biomolecules by using conventional as well as colorimetric detection methods with silver nanoparticles.

The liver is one of the vital organs in the body, and the gold standard of treatment for liver function impairment is liver transplantation, which poses many challenges. The specific 3D structure of liver, which significantly impacts the growth and function of its cells, has made biofabrication with the 3D printing of scaffolds suitable for this approach. In this study, to investigate the effect of scaffold geometry on the performance of HepG2 cells, Poly-Lactic acid (PLA) polymer was used as the input of the Fused Deposition Modeling (FDM) 3D-printing machine. Samples with simple square and bioinspired hexagonal cross-section designs were printed. 1% and 2% of gelatin-coating were applied to the 3D printed PLA to improve the wettability and surface properties of the scaffold. SEM pictures were used to analyze the structural properties of PLA-Gel hybrid scaffolds, EDS to investigate the presence of gelatin, water contact angle measurement for wettability, and weight loss for degradation. In vitro tests were performed by culturing HepG2 cells on the scaffold to evaluate the cell adhesion, viability, cytotoxicity, and specific liver functions. Then, high-precision scaffolds were printed and the presence of gelatin was detected. Also, the effect of geometry on cell function was confirmed in viability, adhesion, and functional tests. The albumin and urea production of the Hexagonal PLA scaffold was about 1.22 ­±0.02 fold higher than the square design in 3 days. This study will hopefully advance our understanding of liver tissue engineering toward a promising perspective for liver regeneration.

Herein we report the use of Pseudomonas putida F1 biofilms grown on carbonized cellulosic fibers to achieve biodegradation of airborne VOCs in the absence of any bulk aqueous phase media. It is believed that direct exposure of gaseous VOC substrates to biomass may eliminate aqueous phase mass transfer resistance and facilitate VOC capture and degradation. When tested with toluene vapor as a model VOC, the supported biofilm could grow optimally at 300 ppm toluene and 80% relative humidity, with a specific growth rate of 0.425 day -1. During long-term VOC biodegradation tests in a tubular packed bed reactor, biofilms achieved a toluene degradation rate of 2.5 mg g DCW -1 h -1 during the initial exponential growth phase. Interestingly, the P. putida F1 film kept biodegrading activity even at the subsequent stationary non-growth phase. The supported biofilms with a biomass loading of 20% (wt) could degrade toluene at a rate of 1.9 mg g DCW -1 h -1 during the stationary phase, releasing CO 2 at a rate of 6.4 mg g DCW -1 h -1 at the same time (indicating 100% conversion of substrate carbon to CO 2). All the specific degradation rates are much higher than what can be gleaned from previously reported work. It also demonstrates the feasibility of biofilm growth and direct gas phase degradation of VOCs without requiring any bulk aqueous phase.

Coronavirus disease 2019 (COVID-19) is the most prevalent disease in society today, and vaccination is a powerful weapon against COVID-19. However, there have been many recent reports of vaccine-induced skin side effects. Autoimmune bullous reactions caused by the COVID-19 vaccine are rare. We identified a case of refractory PV associated with COVID-19 vaccination that improved after 2 RTX injections.

Most studies exploring land use impacts have focused on taxonomic metrics, but interest in the functional approach has increased because it helps to understand the relationships between community structure and functioning of aquatic ecosystems. We evaluated how functional and taxonomic approaches contribute to assessing the effects of land use on macroinvertebrate assemblages of lowland streams. We also studied the relationships between both approaches. We sampled benthic macroinvertebrates in 17 sites with different land uses (agricultural, peri-urban, and extensive livestock). We computed the taxonomic metrics and biotic indexes as well as functional richness (FRic), divergence (FDiv), dispersion (FDis), and Rao diversity indexes for each site. We performed general linear mixed models to compare land-uses and also performed correlation analysis between taxonomic and functional indexes. Taxonomic richness was significantly higher in extensive livestock than in the other two land uses, while Shannon diversity was significantly different between land uses (extensive livestock>peri-urban>agriculture). FRic and FDiv were significantly lower in peri-urban land use than in agricultural and extensive livestock sites. Only taxonomic richness showed a significant and positive relationship with FRic, FDis, and Rao, but they fit better to a logarithmic function. Therefore, an increase in taxonomic richness and Shannon diversity did not necessarily imply an increase in the functional aspects of the macroinvertebrate assemblage. Using only one of these approaches could lead to partial evaluations and loss of information. Combining them could improve bioindication and predictive potential and help assess the effects of multiple stressors on freshwater ecosystems to improve biomonitoring.

Machine learning (ML) is the study of computer algorithms that can improve automatically through experience and by the use of data artificial intelligence is associated with it. Machine learning algorithms create a model based on training data to make predictions or judgments without having to be explicitly programmed to do so. Machine learning algorithms are utilized in a wide range of applications, including medicine, email filtering, speech recognition, and computer vision, where developing traditional algorithms to do the required tasks is difficult or impossible.

The increasing use of milk proteins in medicine requires the development of effective processes for sterilization of milk formulations. We found that epigallocatechin-3-gallate (EGCG) was able to reduce bacterial flora in total casein, depending on the concentration of EGCG. Furthermore, the combination of EGCG and gamma radiation reduced the dose D10 to 0.88 kGy and 0.63 kGy with 250 and 500 µM EGCG, respectively, instead 2.01 kGy without EGCG. We also examined the effect of gamma radiation on alpha- and beta-casein in the absence and presence of epigallocatechin-3-gallate (EGCG). Milk proteins in solution were exposed to different doses of gamma radiation with and without EGCG. Unirradiated and irradiated samples were analyzed by SDS-PAGE and matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-MS). Our results suggest that EGCG (10 µM) protects α- and β-casein from degradation and subsequent polymerization, possibly by scavenging oxygen and protein free radicals generated during irradiation. Although we used a ratio of polyphenols to protein that was higher for alpha-casein (1/5) than beta-casein (1/10), beta-casein was better protected with EGCG. According to previous studies, this result could be explained by differences in protein primary structure and its interaction with EGCG. The interaction of EGCG with casein is hydrophobic rather than hydrophilic, so the interaction with β-casein is stronger than with α-casein. In conclusion, we found that low EGCG concentrations enhances the sterilization of total casein by gamma radiation and it provided an excellent radioprotection of α- and β-casein, especially β-casein, against degradation and aggregation.

We report two cases of Schloffer tumor that required resection after radical colon cancer surgery because of suspected lymph node recurrence on contrast-enhanced (CE) CT and 18F-FDG-PET/CT.Case1 is 69-year-old man with sigmoid colon cancer pStage IIA and case 2 is a 67-year-old male with descending colon cancer pStage IIIB.

Persistent left superior vena cava (SVC) without the right SVC is very rare and occurs in 0.07%–0.13% of patients with congenital heart defects. An enlarged coronary sinus detected during cardiac examination in the prenatal period is the first finding that raises suspicion for this anomaly. In this report, a patient was presented who was referred with the prediagnosis of cor triatriatum sinister in the antenatal period and diagnosed with isolated persistent left SVC.

Hemorrhagic cholecystitis is a rare complication of acute cholecystitis. Hemorrhage in the gallbladder can occur for a variety of reasons (gallstone cholecystitis, secondary to trauma, percutaneous procedures, neoplasms, bile parasites, or disorders of hemostasis).CT scan can help the diagnosis. We report a case of hemorrhagic cholecystitis complicated by gallbladder perforation

From decomposition method for operators, we consider Newton-like iterative processes for approximating solutions of nonlinear operators in Banach spaces. These iterative processes maintain the quadratic convergence of Newton's method. Since the operator decomposition method has its highest degree of application in non-differentiable situations, we construct Newton-type methods using symmetric divided differences, which allow us to improve the accessibility of the methods. Experimentally, by studying the basins of attraction of these methods, observe an improvement in the accessibility of derivative-free iterative processes that are normally used in these non-differentiable situations, such as the classic Steffensen's method. In addition, we study both the local and semi-local convergence of the Newton-type methods considered.

We propose a modification of a method based on Fourier analysis to obtain the Floquet characteristic exponents for periodic homogeneous linear systems, which shows a high precision. This modification uses a variational principle to find the correct Floquet exponents among the solutions of an algebraic equation. Once we have these Floquet exponents, we determine explicit approximated solutions. We test our results on systems for which exact solutions are known to verify the accuracy of our method including one dimensional periodic potentials of interest in quantum physics. Using the equivalent linear system, we also study approximate solutions for homogeneous linear equations with periodic coefficients.

Introduction: In March 2020, new guidelines allowed patients with epistaxis to be discharged home with nasal packs in situ to reduce the risk of inpatient covid transmission rates. Our objective is to review how successful these new guidelines have been and whether they could be safely maintained in future practice. Methods: This was a retrospective data analysis at a local tertiary ENT referral hospital. The study group consisted of patients admitted with epistaxis over one year. The “Pack and Home” criteria pathway was implemented. We reviewed the pathway 6 months pre and 6 months post pathway introduction. Primary outcome measure included compliance with the “Pack and Home” criteria and length of inpatient admissions. Results: A total of 131 patients required nasal packing, with 72 patients (55%) in loop 1 and 59 patients (45%) in loop 2. In the first loop all 72 patients (100%) were admitted for inpatient care. However, in the second loop 21 patients (36%) were discharged home with nasal pack in situ and 59 patients (64%) were admitted. Of those discharged, 2 patients re-presented after 48 hours with re-bleeding. The average total length of inpatient stay in loop 1 was significantly higher at 45.7 hours and 29.6 hours in loop 2 (p<0.05). All discharged patients attended their outpatient appointment in under 3 days. Conclusion The “Pack and Home” criteria can successfully identify patients who are suited for an outpatient management pathway. This could reduce surgical inpatient load and the way we manage epistaxis.

Abstract Introduction Crooked nose deformity is a vertical axis deviation of the nasal pyramid; despite all advancements, it remains a significant problem to resolve. In this study, we present our I- and C-shaped crooked nose rhinoplasty results with this new osteotomy technique. Method This study included 25 patients with I- or C-shaped crooked nose deformities who underwent correction with a closed-approach let-down procedure. In this technique, the middle vault is preserved, the bony cap is mobilized and preserved, and the lateral nasal bones are equalized by a piezo device or classical osteotomes. By the mobilization of the bony cap, tension on the dorsal septum is released, and slight asymmetries are hidden behind this mobile bony cap. Results The postoperative angles for both type I and C deformities were closer to the ideal angle, and the difference was statistically significant. All patients were satisfied with their aesthetic and functional results. Conclusion In this procedure, we correct asymmetries at the lower maxillary nasal junction, such as in the Let-down approach, as well as asymmetries at the K-point, such as in the structural approach. Thus, we combine the advantages of both techniques. Additionally, the mobile-bony cap left on the patient is very useful for releasing the tension of the septal dorsum and hiding slight asymmetries that remain below in the patients.

In this study, the improved Tietz potential was used to describe the internal vibration of a diatomic molecule. With the help of the expression for bound state energy levels, a more generalized equation for the upper bound vibrational quantum number and canonical partition function were obtained for the diatomic system. The obtained partition function was used to derive analytical equation for the prediction of constant pressure (isobaric) molar heat capacity of diatomic molecules. The analytical model was used to predict the constant pressure molar heat capacity data of the ground state CO, BBr, HBr, HI, P2, KBr, Br2, PBr, SiO and Cl2 molecules. The upper bound vibrational quantum number obtained for the molecules are 85, 100, 21, 21, 115, 301, 89, 157, 110 and 67. The computed average absolute deviation are 2.3462%, 1.1342%, 2.3350%, 1.9078%, 0.7268%, 2.4041%, 1.7849%, 1.8989%, 2.5209% and 2.1523%. The present results are in good agreement with available literature data on gaseous molecules.

Introduction Ventricular tachycardias although they may be irregular at the onset, after several seconds they organize into a stable cycle length. Methods/Results We report a rare case of an “irregular ventricular tachycardia” in which the oscillations in cycle length were so pronounced that it was initially misdiagnosed as atrial fibrillation with aberrant conduction. The initial pharmacological management and detained electrophysiological study are presented. Conclusion An unusual irregular ventricular tachycardia can originate from the moderator band and result in a tachycardia induced cardiomyopathy

In this letter, a high-performance photodetector was established with the 4H-SiC structure for the high-speed optocoupler. It is found that the band gap of the doped 4H-SiC is reduced, where the electrons can transmit to the conduction band easier. It improves the photoelectric response speed and the light absorption rate of the system is effectively improved. Under the 840nm incident light, the transient response of the optocoupler are 210ns and 155ns, respectively. During the temperature changed, the maximum variation value is 12ns. The response speed of the whole chip is increased and it changed very little with the variation of the input photocurrent and the operation temperature.

Introduction: Radiofrequency ablation (RFA) slow pathway modification for catheter ablation of AV nodal reentrant tachycardia (AVNRT) is traditionally performed using a 4mm, non-irrigated (NI) RF ablation catheter. Slow pathway modification using irrigated, contact-force sensing (ICFS) RFA catheters has been described in case reports, but outcomes have not been systematically evaluated. Methods: Acute procedural outcomes of 200 consecutive patients undergoing slow pathway modification for AVNRT were analyzed. An ICFS 3.5mm RFA catheter (ThermoCool SmartTouch STSF, Biosense Webster, Inc.) was utilized in 134 patients, and a 4mm NI RFA catheter (EZ Steer, Biosense Webster, Inc.) was utilized in 66 patients. Electroanatomic maps were retrospectively analyzed in a blinded fashion to determine proximity of ablation lesions to the His region. Results: Baseline characteristics of patients in both groups were similar. Total RF time was significantly lower in the ICFS group compared to the NI group (5.53±4.6 vs. 6.24±4.9 min, p=0.03). Median procedure time was similar in both groups, ICFS 108.0 (87.5-131.5) vs. NI 100.0 (85.0-125.0) min, p=0.2). Ablation was required in closer proximity to the His region in the NI group compared to the ICFS group (14.4 ± 5.9 mm vs, 16.7 ± 6.4 mm, respectively, p=0.01). AVNRT was rendered non-inducible in all patients, and there was no arrhythmia recurrence during follow-up in both groups. Catheter ablation was complicated by AV block in one patient in the NI group. Conclusion: Slow pathway modification for catheter ablation of AVNRT using an irrigated, contact-force sensing RFA catheter is feasible, safe, and may facilitate shorter duration ablation while avoiding ablation in close proximity to the His region.
