Enzyme-assisted extraction of aflatoxin M1 in Brazilian artisanal cheese using reversed-phase liquid chromatography.

Brazil is an influential and successful food-producing country, where we can highlight artisanal cheeses gaining visibility in foreign markets. Some of these cheeses are made from raw milk, making them susceptible to contamination by microorganisms, including fungi, which can produce harmful mycotoxins. Feed contaminated with aflatoxin B1, when consumed by dairy animals, is metabolized and transformed into aflatoxin M1 (AFM1), which is excreted in milk.

Aim: The aim of this study is to analyse the cost of in-hospital falls comparing those who had falls to nonfalls patients while accounting for several risk factors associated with falls.

Methods: Data were collected from January 2020 to December 2022, in a private hospital in Brazil.

Plasmodium SEY1 is a novel druggable target that contributes to imidazolopiperazine mechanism of action.

The precise mode of action of ganaplacide (KAF156), a phase III antimalarial candidate, remains elusive. Here we employ omics-based methods with the closely related chemical analog, GNF179, to search for potential targets. Ranking potential targets derived from chemical genetics and proteomic affinity chromatography methodologies identifies , or Synthetic Enhancement of YOP1, which is predicted to encode an essential dynamin-like GTPase implicated in homotypic fusion of endoplasmic reticulum (ER) membranes.

Development of peptoid-based heteroaryl-decorated histone deacetylase (HDAC) inhibitors with dual-stage antiplasmodial activity.

Dynamics of epigenetic modifications such as acetylation and deacetylation of histone proteins have been shown to be crucial for the life cycle development and survival of Plasmodium falciparum, the deadliest malaria parasite. In this study, we present a novel series of peptoid-based histone deacetylase (HDAC) inhibitors incorporating nitrogen-containing bicyclic heteroaryl residues as a new generation of antiplasmodial peptoid-based HDAC inhibitors. We synthesized the HDAC inhibitors by an efficient multicomponent protocol based on the Ugi four-component reaction.

Stifle arthrodesis in dogs using semi-circular saw: Cadaveric study.

Understanding parasite resistance to benznidazole is crucial for developing new drugs to treat CD.

Areas Covered: Here, the authors review the current understanding of the molecular basis of benznidazole resistance.

Recurrent community-acquired pneumococcal meningitis in adults with and without identified predisposing factors.

Bacterial meningitis is still a significant public health concern, with high morbidity and mortality rates. Despite this, it is still a rare event that requires the bacterial invasion of the meninges. However, some predisposing factors can trigger recurrent episodes of meningitis.

Structure-Activity Relationship of a Pyrrole Based Series of PfPKG Inhibitors as Anti-Malarials.

Controlling malaria requires new drugs against . The cGMP-dependent protein kinase (PfPKG) is a validated target whose inhibitors could block multiple steps of the parasite's life cycle. We defined the structure-activity relationship (SAR) of a pyrrole series for PfPKG inhibition.

BMP6 and VDR gene polymorphisms are associated with osteonecrosis in a sickle cell anaemia cohort.

The occurrence and severity of osteonecrosis in sickle cell anaemia (SCA) vary due to risk factors, including genetic modifiers. Bone morphogenetic proteins (BMPs), particularly BMP6, and the vitamin D receptor (VDR) play key roles in cartilage and bone metabolism, making them potential contributors to orthopaedic outcomes in SCA. Here, we evaluated the association of polymorphisms in BMP6 (rs3812163, rs270393 and rs449853) and VDR (FokI rs2228570 and Cdx2 rs11568820) genes with osteonecrosis risk in a Brazilian SCA cohort.
