The study of mycobiota remains relatively unexplored due to the lack of sufficient available reference strains and databases compared to those of bacterial microbiome studies. Deep sequencing of Internal Transcribed Spacer (ITS) regions is the de facto standard for fungal diversity analysis. However, results are often biased because of the wide variety of sequence lengths in the ITS regions and...

Migren, beyindeki sinir ve kan damarlarında meydana gelen değişimler sonucunda ortaya çıkan şiddetli bir baş ağrısı hastalığıdır. Migren hastalığının biyomedikal cihazlarla teşhisine dair yöntem henüz geliştirilmemiştir ancak literatürü incelediğimizde EEG sinyalleri kullanılarak migren teşhisi ile ilgili birçok çalışmanın yapıldığını görmekteyiz. Bu çalışmada 18 hastası 21 kontrol grubundan ol...

Abstract We analyze the characteristics of atmospheric variations over tropical South America using pattern recognition framework weather typing or circulation patterns (CPs). During 1979-2020, nine CPs are defined in region, a k-means algorithm based on daily unfiltered 850 hPa winds 0035°N-30°S, 90°W-30°W. primarily interpreted as stages annual cycle low-level circulation. identified three “w...

Conjugate vaccines belong to the most efficient preventive measures against life-threatening bacterial infections. Functional expression of N-oligosaccharyltransferase (N-OST) PglB of Campylobacter jejuni in Escherichia coli enables a simplified production of glycoconjugate vaccines in prokaryotic cells. Polysaccharide antigens of pathogenic bacteria can be covalently coupled to immunogenic acc...

Purpose We investigated the possibility of the nanocomplex of poly(ethylene glycol) (PEG) and catechin as a new biomedical material to treat dry eye disease. Methods NOD.B10.H2b mice were exposed to an air draft and injected with scopolamine for 10 days. Ten days later, the mice were treated with normal saline (n = 11), 1% catechin (n = 11), 1% PEG (n = 11), and 1% catechin/PEG nanocomplex so...

Carbon catabolite protein A (CcpA) is known to function as a major regulator of gene expression in different gram-positive organisms. Deletion of the ccpA homologue (saCOL1786) in Staphylococcus aureus was found to affect growth, glucose metabolization, and transcription of selected virulence determinants. In liquid culture, deletion of CcpA decreased the growth rate and yield; however, the eff...

We have investigated the anticancer effects of the dietary isothiocyanate sulforaphane (SFN) on colorectal cancer (CRC), using primary cancer cells lines isolated from five Taiwanese colorectal cancer patients as the model for colorectal cancer. SFN-treated cells accumulated in metaphase (SFN 6.25 μM) and subG1 (SFN 12.5 and 25 μM) as determined by flow cytometry. In addition, treated cells sho...

Many bovine Staphylococcus aureus isolates from Argentina are nontypeable (NT), i.e., they do not produce serotype 5 or 8 capsular polysaccharides (CPs). Some of these NT strains have a deletion of the cap5(8) gene cluster mediated by a variant of IS257, now designated IScap. IScap showed 93% amino acid identity to S. aureus ORF49 but only 85% identity to IS431 from S. aureus N315 and 88% ident...

Bovine mastitis caused by Staphylococcus aureus is responsible for major economic losses to the dairy industry, and more-effective therapeutic or preventive approaches are sorely needed. The predominance of staphylococcal capsular polysaccharide types 5 and 8 among human isolates from many sources is well documented, but there seems to be a greater variation in the distribution of capsular sero...
