are significant spoilage bacteria in raw milk and dairy products, primarily due to their ability to form biofilms and resist disinfection. This study explored the effects of the phage combined with sodium hypochlorite in reducing biofilms on stainless steel at various temperatures and ages. Biofilms were formed using UFV 041 in UHT milk, incubated at 4 °C and 30 °C for 2 and 7 days.

  • * This study analyzed the genomes of four specific HN/AD bacterial strains (UFV5, UFV3, UFV2, and UFV4) and found that while they have genes for amino acid and protein production, there were no common nitrogen metabolism genes across the strains.
  • * The researchers identified nine potential candidate genes linked to the HN/AD process by comparing these bacterial genomes with existing transcriptomic data, contributing to a better understanding of how these bacteria function in ammonia removal.

Background: There are many gaps in our understanding of the mechanisms involved in ovarian follicular development in cattle, particularly regarding follicular deviation, acquisition of ovulatory capacity, and preovulatory changes. Molecular evaluations of ovarian follicular cells during follicular development in cattle, especially serial transcriptomic analyses across key growth phases, have not been reported. This study aims to address this gap by analyzing gene expression using RNA-seq in granulosa and antral cells recovered from ovarian follicular fluid during critical phases of ovarian follicular development in Holstein cows.

Bacteria of the species belong to the family , are Gram-negative bacilli, are moderately thermophilic and are included in the group of thiosulfate-reducing bacteria, being capable of significantly accelerating corrosion in metallic structures. However, no in-depth study on the genome, antibiotic resistance and mobile elements has been carried out so far. In this work, the isolation, phenotypic and genotypic characterization of the multi-resistant UFV_LIMV02 strain was carried out, from water samples from an offshore oil extraction platform in Rio de Janeiro (Brazil).

Background: In intensive care units (ICUs), infections by multidrug-resistant (MDR) microorganisms should be monitored to prevent healthcare-associated infections (HAIs).

Methods: From 2018 to 2020, we investigated all medical records of patients admitted to the ICU of a public university hospital. All patients colonized/infected by MDR microorganisms and submitted to active surveillance cultures (ASCs) were included.

Objective: To evaluate accuracy and agreement between creatinine clearance (CrCl) measured in 12-h urine and glomerular filtration rate (GFR) calculated by the Modification of Diet in Renal Disease (MDRD-4) and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formulas, with and without adjustment for race/color.

Methods: Baseline data from the Longitudinal Study of Adult Health (ELSA-Brazil) in adults (35-74 years of age) of both genders were used. Serum creatinine was measured in fasting blood and urinary creatinine was measured in an overnight 12-h urine collect.

Aluminum (Al) toxicity limits crop production worldwide. Although studies have identified genes associated with Al tolerance in crops, a large amount of data remains unexplored using other strategies. Here, we searched for single substitutions and InDels across differentially expressed genes (DEGs), linked DEGs to Al-tolerance QTLs reported in the literature for common maize, and investigated the alternative splicing regulated by Al toxicity.

  • Sexual rest in bulls leads to lower conception rates, shown by high volumes of ejaculate with many dead sperm, although the exact biochemical reasons are not fully understood.
  • A study with six Nellore bulls evaluated their semen through collections, revealing significant differences in sperm quality and biochemical markers between the first and fourth ejaculates.
  • Findings indicated that the first ejaculate had poorer enzyme activity and higher lipid peroxidation, whereas the fourth ejaculate showed better sperm quality due to differences in fatty acid composition and protein abundance.

  • This study looked at how to better find people at risk of developing diabetes using different testing methods.
  • Researchers used data from a group of people in Brazil to compare traditional tests to new score-based methods.
  • They found that the score-based methods were better at identifying high-risk individuals without incorrectly labeling too many others as at risk.

Objective: We aimed to characterize the relationship between severe chronic alcoholism and hepatic arterial wall disorders in humans.

Methods: We obtained hepatic arteries from 165 patients undergoing liver transplantation who were placed into two etiological groups: an Alcoholism group and a Non-alcoholism group. We compared the age, sex, lipid profile, and histologic characteristics of the hepatic arteries (normal, reduction in luminal diameter of ≤10%, or atherosclerosis) of the participants in the two groups using multifactor analyses.

Patients infected by the SARS-CoV-2 virus are commonly diagnosed with threatening liver conditions associated with drug-induced therapies and systemic viral action. RNA-Seq data from cells in bronchoalveolar lavage fluid from COVID-19 patients have pointed out dysregulation of kallikrein-kinin and renin-angiotensin systems as a possible mechanism that triggers multi-organ damage away from the leading site of virus infection. Therefore, we measured the plasma concentration of biologically active peptides from the kallikrein-kinin system, bradykinin and des-Arg-bradykinin, and liver expression of its proinflammatory axis, bradykinin 1 receptor (B1R).
