We analyse two cases of Bovine Serum Albumin (BSA) allergy. The first regards a female laboratory technician with a history of bronchial asthma due to cat allergy, who developed an exacerbation of bronchial symptoms as a consequence of BSA powder inhalation at work. To date, sensitization to BSA as a cause of occupational asthma has rarely been reported in the scientific literature. The second case concerns a woman with a similar cat sensitivity, who presented an oral allergy syndrome-type clinical reaction, gastric pain and diarrhoea immediately after eating cooked pork meat. Subsequently, she developed the same reaction after eating goat meat and goat cheese, and then also after eating beef. Both patients resulted specifically sensitized to BSA and to other mammalian serum albumins which play a role as panallergens in animals. The two cases show that BSA, a well known cause of food allergy in childhood, may also provoke symptoms of food allergy in adulthood, though in case of powder inhalation, it may provoke respiratory symptoms. Prior animal sensitization appears to represent a risk factor.

This study aimed to develop and evaluate a novel fibroblast activation protein (FAP)-specific tracer, fluorine-18-labeled fibroblast activation protein inhibitor-FUSCC-07 ([F]F-FAPI-FUSCC-07), for use in both preclinical and clinical settings. Preclinical evaluations were conducted to assess the stability and partition coefficient of [F]F-FAPI-FUSCC-07. Experiments involving human glioma U87MG cells demonstrated its cellular uptake and inhibitory properties.

Early detection of bovine mastitis-causing pathogens is necessary for treatment. As culturing methods are time-consuming, a more rapid detection technique is required. This study investigated the sensitivity, specificity, and detection limit of Gram staining of milk precipitates (milk Gram stain, MGS) to detect bovine mastitis-causing pathogens in milk, as well as the potential of MGS to diagnose inflammation by counting polymorphonuclear leukocytes (PMN).

Purpose: This study aims to investigate whether zinc ion (Zn) alleviates myocardial ischemia-reperfusion injury (MIRI) through the MAM-associated signaling pathway and to explore its impact on ERS and calcium overload.
Methods: H9C2 cells were cultured in a DMEM supplemented with 10 % fetal bovine serum and 1 % antibiotic solution. A MIRI model was established through simulated ischemia and reoxygenation with Zn treatment in a complete medium.

The protozoan parasite Neospora caninum is an important cause of abortion in cattle. Infection occurs horizontally by ingestion of oocysts shed by canids or vertically, from an infected dam to the foetus, and may result in abortion, stillbirth, or the birth of subclinically infected offspring. We estimated the occurrence of N.

This review paper provides an inclusive overview of the intricate interactions amid ionic liquids (ILs) and essential biomacromolecules, mainly Hemoglobin (Hb), Bovine Serum Albumin (BSA), Human Serum Albumin (HSA), and Calf Thymus-DNA (CT-DNA). ILs have recently become a topic of great attention because of their inimitable physicochemical properties and potential uses in different fields. The review systematically explores the binding mechanisms, thermodynamics, and structural changes induced by ILs on Hb, BSA, HSA, and CT-DNA using spectroscopic, thermodynamic, and computational techniques.
