The aim of this study was to discuss the functions of FKS family genes which encode β-1, 3-glucan synthase regarding the viability and autolysis of yeast strain. Loss of FKS1 gene severely influences the viability and anti-autolytic ability of yeast. Mutation of FKS1 and FKS2 genes led to cell reconstruction, resulting in a sharp shrinkage of cell volume and decreased stress resistance, viability, and anti-autolytic ability. Deletion of FKS3 gene did not clearly influence the synthesis of β-1, 3-glucan of yeast but increased the strain's stress resistance, viability, and anti-autolytic ability...

Temperatures are expected to increase over the next century in all terrestrial biomes and particularly in boreal forests, where drought-induced mortality has been predicted to rise. Genomics research is helping to develop hypotheses regarding the molecular basis of drought tolerance and recent work proposed that the osmo-protecting dehydrin proteins have undergone a clade-specific expansion in the Pinaceae, a major group of conifer trees. The objectives of this study were to identify all of the putative members of the gene family, trace their evolutionary origin, examine their structural diversity and test for drought-responsive expression...

Diatoms (Bacillariophyta) are a species-rich group of eukaryotic microbes diverse in morphology, ecology, and metabolism. Previous reconstructions of the diatom phylogeny based on one or a few genes have resulted in inconsistent resolution or low support for critical nodes. We applied phylogenetic paralog pruning techniques to a dataset of 94 diatom genomes and transcriptomes to infer perennially difficult species relationships, using concatenation and summary-coalescent methods to reconstruct species trees from datasets spanning a wide range of thresholds for taxon and column occupancy in gene alignments...

The superfamily Psylloidea (Hemiptera: Sternorrhyncha) lacks a robust multigene phylogeny. This impedes our understanding of the evolution of this group of insects and, consequently, an accurate identification of individuals, of their plant host associations, and their roles as vectors of economically important plant pathogens. The conserved nuclear gene elongation factor-1 alpha (EF-1α) has been valuable as a higher-level phylogenetic marker in insects and it has also been widely used to investigate the evolution of intron/exon structure...

Although the use of the posterior mediastinum and the stomach as a reconstruction option after esophagectomy has large acceptance all over the world, there are concerns about the potential respiratory impairment it could cause. We prospectively studied 35 patients regarding the forced expiratory volume and vital capacity. The patients were studied preoperatively and between the 45th and 60th postoperative days. The value of both parameters decreased, although they were still within normal clinical ranges. We concluded that this type of reconstruction does not harm the patients regarding the respiratory flow rates...

Motivation: Advances in the sequencing of uncultured environmental samples, dubbed metagenomics, raise a growing need for accurate taxonomic assignment. Accurate identification of organisms present within a community is essential to understanding even the most elementary ecosystems. However, current high-throughput sequencing technologies generate short reads which partially cover full-length marker genes and this poses difficult bioinformatic challenges for taxonomy identification at high resolution...

Motivation: Microarray technology can be used to study the expression of thousands of genes across a number of different experimental conditions, usually hundreds. The underlying principle is that genes sharing similar expression patterns, across different samples, can be part of the same co-expression system, or they may share the same biological functions. Groups of genes are usually identified based on cluster analysis. Clustering methods rely on the similarity matrix between genes...

Background and Aims: Recent biogeographic studies have illustrated that Quaternary climatic changes and historical orogenies have driven the development of high levels of biodiversity. In this context, phylogenetic niche conservatism may play a role as a major precursor of allopatric speciation. However, the effects of niche evolution on the diversification patterns of plant species under rapid habitat changes are still unknown. Here, Primula section Reinii, one of the few primroses endemic to the Japanese Archipelago, was investigated...

Background: Auricular reconstruction is one of the most challenging procedures in plastic surgery. An adequate skin envelope is essential for cartilage framework coverage, yet few good options exist without additional surgery. We propose a novel method for minimally invasive tissue expansion, using hyaluronic acid (HA) filler to allow for single-stage ear reconstruction. Objectives: To introduce the novel concept of HA filler for tissue expansion in ear reconstruction, and as an alternative to traditional expansion techniques...

BACKGROUND: Of the many issues regarding surgical techniques for posterior cruciate ligament (PCL) reconstruction, the choice between single-bundle (SB) and double-bundle (DB) reconstruction is one of the most debated. However, it is unclear which of the reconstruction techniques yields better outcomes in knees with a PCL injury. The purpose of this meta-analysis was to compare the benefits of SB and DB PCL reconstruction in terms of biomechanical outcomes. METHODS: The MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and SCOPUS electronic databases were searched for relevant articles comparing the outcomes of SB and DB PCL reconstruction that were published up until August 2016...

OBJECTIVE: To describe a new technique for the reconstruction of parieto-occipital skull deformities. METHODS AND RESULTS: The technique is a variant of the previously described "cathedral dome procedure" used for frontal skull deformities. The authors apply the same principle of remodeling by making meridional slat craniotomies surrounding the depressed dome of the posterior skull deformity, followed by "green-stick fracture-reshaping" of the meridional slats to elevate and support the excised depressed dome...

BACKGROUND: The optimal technique for arthroscopic rotator cuff repair is controversial, and both single and double-row techniques are commonly used. In the current era of increasing costs, health-care delivery models are focusing on the value of care. In this study, we compared the cost-effectiveness of single-row and double-row reconstructions in patients undergoing arthroscopic rotator cuff repair. METHODS: A cost-utility analysis was performed from the perspective of a publicly funded health-care system...

Clonorchis sinensis is an important foodborne zoonosis worldwide and prevalent in China for more than 2000 years. According to the experience of controlling Schistosoma japonica, China started to establish the integrated control strategy for C. sinensis in endemic areas. Lou village, the largest village in Shenzhen city in South China was taken as a pilot site. This longitudinal study assessed the infection status of C. sinensis among people and intermediate hosts from 2006 to 2014 in Lou village. After a continuous intervention with the integrated control strategy, the prevalence of C...

PURPOSE: To see the gross tumor volume (GTV) dependency according to the phase selection and reconstruction methods, we measured and analyzed the changes of tumor volume and motion at each phase in 20 cases with lung cancer patients who underwent image-guided radiotherapy. MATERIALS AND METHODS: We retrospectively analyzed four-dimensional computed tomography (4D-CT) images in 20 cases of 19 patients who underwent image-guided radiotherapy. The 4D-CT images were reconstructed by the maximum intensity projection (MIP) and the minimum intensity projection (Min-IP) method after sorting phase as 40%-60%, 30%-70%, and 0%-90%...
