Abstract:
Staphylococcal enterotoxins are the leading cause of human food poisoning worldwide. Staphylococcus spp. are the main mastitis-causing agents in goats and frequently found in high counts in goat milk. This study aimed to investigate the occurrence of enterotoxin-encoding genes in Staphylococcus aureus associated with mastitis in lactating goats in Paraiba State, Brazil. Milk samples (n=2024) were collected from 393 farms. Staphylococcus aureus was isolated in 55 milk samples. Classical (sea, seb, sec, sed, see) and novel (seg, seh, sei) enterotoxin-encoding genes were investigated by means of

Abstract:
The ATAC-seq and RNA-seq have been widely used in the epigenomes analysis of mammals. However, there is a lack of comprehensive integrated analysis of ATAC-seq and RNA-seq data.

One strategy is a joint analysis by integrating Hi-C data with ATAC-seq and RNA-seq data. The other strategy is to investigate the association between ATAC-seq and RNA-seq data only based on genome physical distance in the case of no availability of Hi-C data. Hi-C data-bas

Abstract:
Staphylococcal food poisoning (SFP) is one of the most significant foodborne diseases. It is a mild intoxication, which is caused by the ingestion of food containing one or more preformed staphylococcal enterotoxins (SEs). The toxic dose of SEs in human is usually ranged from 20 ng to 1 μg. SEs are proteins produced by Staphylococcus spp in various parts of the environment, including foods. Although several staphylococci can produce SEs, the majority of SFP cases is attributed to S. aureus. Traditionally, five antigenic SE types have been recognized: SEA, SEB, SEC, SED and SEE.

Despite this advance, analysis of the resulting data is challenging, and large scale scATAC-seq data are difficult to obtain and expensive to generate. This motivates a method to leverage information from previously generated large scale scATAC-seq or scRNA-seq data to guide our analysis of new scATAC-seq datasets. We analyze scATAC-seq data using latent Dirichlet allocation (LDA), a Bayesian algorithm that was developed to model text corpora, summarizing documents as mixtures of topics def

Abstract:
Abstract Background: Relapse from acute lymphoblastic leukemia (ALL) is one of the most common causes of pediatric cancer-related death. Early relapse of ALL is associated with recurrent mutations of histone methyltransferase NSD2 (nuclear receptor binding SET domain protein 2), which is specific for H3K36me2, suggesting a link to therapy resistance or other mechanisms underlying relapse such as central neural system (CNS) infiltration. NSD2 p.E1099K affects gene expression through disturbing the balance of H3K36me2/H3K27me3. Using CRISPR/Cas9-edited isogenic ALL cell lines and PDX cells, we f

The striped venus Chamelea gallina is a bivalve mollusc that represents one of the most important fishery resources of the Adriatic Sea. In this work, we investigated for the first time the ability of this species to modulate the expression of genes encoding proteins involved in biomineralization process in response to biotic and abiotic factors. We provided the first comprehensive transcriptome from the mantle tissue of clams collected in two sampling sites located along the Italian Adriatic coast and characterized by different environmental features.

Fifty-five (26.6%) of 207 strains of S. aureus tested produced staphylococcal enterotoxins A (SEA), B (SEB), C (SEC), D (SED) or E (SEE).

Cancer stem cells (CSCs) are closely associated with tumor initiation, metastasis, chemoresistance, and recurrence, which represent some of the primary obstacles to cancer treatment.

Here, we report that Sec C effectively inhibited colorectal CSCs and non-CSCs concurrently, mainly by inhibiting proliferation, self-renewal, metastasis, and drug resistance.

Abstract For an element 𝑤 of a Coxeter group 𝑊, there are two important attributes, namely its length, and its expression as a product of disjoint cycles in its action on Φ, the root system of 𝑊.

Writing w = c 1 ⁢ ⋯ ⁢ c r w=c_{1}\cdots c_{r} as a product of disjoint cycles, we associate to each cycle c i c_{i} a “crossing number” κ ⁢ ( c i ) \kappa(c_{i}) , which is the number of positive roots 𝛼 in c i c_{i} for which w ⋅ α w\cdot\alpha is negative
