Peccaries (collared peccary-CP-and white-lipped peccary-WLP) are an essential source of protein and income for rural communities in the Amazon region. Since 1980s, researchers in the Amazon have reported recurrent local disappearances of WLP populations. Although such disappearances impact the species conservation and the food security of rural societies, no studies have drawn consistent conclusions about the causes of these population collapses.

Agreement between methods to assess potassium intake in patients with chronic kidney disease.

Clin Nutr ESPEN

January 2025

Post Graduation Program in Medical Science, Rio de Janeiro State University, Rio de Janeiro, 20550-900, Brazil; Department of Applied Nutrition, Nutrition Institute, Rio de Janeiro State University, Rio de Janeiro, 20550-900, Brazil. Electronic address:

Background & Aims: In the general population, 24-hour urine potassium excretion is considered the reference standard for estimating potassium intake. However, its agreement with food records and spot urine collections in adults living with chronic kidney disease (CKD) is not well-established. Given the risk of hyperkalemia related to changes in renal potassium handling, understanding if this reference standard is appropriate for the CKD population is important.

Proteome changes during the germination and early seedling development of carnauba palm (Copernicia prunifera) under skotomorphogenic conditions.

J Proteomics

January 2025

Departamento de Bioquímica e Biologia Molecular, Programa de Pós-Graduação em Bioquímica, Universidade Federal do Ceará, Fortaleza, Brazil. Electronic address:

We analyze the proteome changes during the development of the carnauba palm (Copernicia prunifera) seedlings under skotomorphogenic conditions, by separating the embryo into its two components: haustorium (HA) and cotyledonary petiole (CP) and established the descriptive and quantitative proteomes of these tissues across four developmental stages. 5205 proteins were identified in HA and 6028 in CP. These proteomes are rich in proteins known to maintain the skotomorphogenic state, and in a complete set of proteins involved in cellular respiration and biosynthesis of secondary metabolites.

Review of advanced sensor system applications in grinding operations.

J Adv Res

January 2025

Department of Mechanics and Strength of Materials, Politehnica University Timisoara, 1 Mihai Viteazu Avenue, 300 222 Timisoara, Romania. Electronic address:

Background: Today, in a wide variety of industries, grinding operations are an extremely important finishing process for obtaining precise dimensions and meeting strict requirements for roughness and shape accuracy. However, the constant wear of abrasive tools during grinding negatively affects the dimensional and surface conditions of the workpiece. Therefore, effective monitoring of the wear process during grinding operations helps to predict tool life, plan maintenance and ensure consistent product quality.

Major depressive disorder (MDD) is a complex neuropsychiatric disorder potentially influenced by factors such as stress and inflammation. Chronic stress can lead to maladaptive brain changes that may trigger immune hyperactivation, contributing to MDD's pathogenesis. While the involvement of inflammation in MDD is well established, the effects of inflammatory preconditioning in animals subsequently exposed to chronic stress remain unclear.

The expansion of urban settlements over native environments may expose biodiversity to a host of emerging contaminants, with unintended ecological effects. This study evaluated patterns of contamination of streamwater by antidepressants in the Upper Tietê River Basin, a watershed of high social, economic and environmental relevance for comprising both the largest urban settlement in South America (the Metropolitan Region of São Paulo) and remnants of a globally important biodiversity hotspot (the Atlantic Rainforest). We sampled 53 third-order streams draining catchments regularly distributed across a gradient in urban cover.

Prospects of cowpea protein as an alternative and natural emulsifier for food applications: Effect of pH and oil concentration.

Int J Biol Macromol

January 2025

Department of Food Engineering and Technology, Institute of Biosciences, Humanities and Exact Sciences, São Paulo State University (UNESP), Street Cristóvão Colombo, 2265, São José do Rio Preto 15054-000, Brazil. Electronic address:

In response to the growing need to expand the knowledge base on novel, more sustainable protein sources, this study investigated the effectiveness of cowpea protein concentrate (CPC) as a natural emulsifying agent, examining the relationships between pH (3-11), oil concentration (2-10 %), and emulsion stability. pH and oil concentration significantly impacted droplet size distribution, with uniformity decreasing in the order of pH 9 > pH 11 > pH 7, which was attributed to droplet coalescence and flocculation. As evidenced by circular dichroism, alkalinity induced a slight increase in the beta-sheet content of CPC, while simultaneously reducing the alpha-helix content.

January 2025

Sao Paulo State University - UNESP, Medical School, GENOTOX Laboratory, Botucatu, Brazil. Electronic address:

We evaluated both environmental (workplace) and biological (urine) exposure to the anesthetic isoflurane concerning the effects of such exposure on the hematological, hepatic, and renal parameters in veterinarians. Samples were collected from exposed and nonexposed (volunteers) groups to assess hematological and several biochemical markers, and isoflurane was measured in the workplace air and veterinarian's urine. Isoflurane was detected at high levels in the air and urine.

Innovative applications of cobalt tungstate nanoparticles (CoWO NPs) are directly linked to their increased production and consumption, which can consequently increase their release into aquatic ecosystems and the exposure of organisms. Microalgae are autotrophic organisms that contribute directly to global primary productivity and provide oxygen for maintaining many organisms on Earth. In this paper, we assessed the toxicity of CoWO NPs when in contact with the freshwater microalga Raphidocelis subcapitata (Chlorophyceae).

Preeclampsia (PE) is a gestational complication affecting 5% to 10% of all pregnancies. PE is characterized by hypertension and endothelial dysfunction, whose etiology involves, among other factors, alterations in the extracellular matrix (ECM) that can compromise vascular remodeling and trophoblast invasion, ie, processes essential for placental development. Endothelial dysfunction is caused by release of antiangiogenic factors, mainly a soluble fms-like tyrosine kinase-1 (sFlt-1), which antagonizes two endothelial angiogenic factors, the vascular endothelial growth factor (VEGF) and placental growth factor (PLGF).

Background: Transarterial chemoembolisation (TACE) is standard of care for patients with unresectable hepatocellular carcinoma that is amenable to embolisation; however, median progression-free survival is still approximately 7 months. We aimed to assess whether adding durvalumab, with or without bevacizumab, might improve progression-free survival.

Methods: In this multiregional, randomised, double-blind, placebo-controlled, phase 3 study (EMERALD-1), adults aged 18 years or older with unresectable hepatocellular carcinoma amenable to embolisation, an Eastern Cooperative Oncology Group performance status of 0 or 1 at enrolment, and at least one measurable intrahepatic lesion per modified Response Evaluation Criteria in Solid Tumours (RECIST) were enrolled at 157 medical sites including research centres and general and specialist hospitals in 18 countries.

BCL11B is a Cys2-His2 zinc-finger (C2H2-ZnF) domain-containing, DNA-binding, transcription factor with established roles in the development of various organs and tissues, primarily the immune and nervous systems. BCL11B germline variants have been associated with a variety of developmental syndromes. However, genotype-phenotype correlations along with pathophysiologic mechanisms of selected variants mostly remain elusive.
