A collaborative study was performed in 13 laboratories to validate an enzyme immunoassay (EIA) procedure for rapid detection of Salmonella in foods. The EIA was compared with the standard culture procedure for detection of Salmonella in 6 food types: ground black pepper, soy flour, dried whole eggs, milk chocolate, nonfat dry milk, and raw deboned turkey. Uninoculated and inoculated samples were included in each food group analyzed. There was no significant difference in the proportion of samples positive by the EIA and culture procedures at the 5% level for any of the 6 foods. The enzyme immunoassay screening method has been adopted official first action as a rapid screening method for detection of Salmonella.

Introduction: The developed domestic retrodipeptide analogue of cholecystokinin tetrapeptide (CCK) (N-(6-phenylhexanoyl)-glycyltryptophan amide, or compound GB-115) with antagonistic properties in relation to CCK1 receptors has anxiolytic activity previously shown in preclinical and clinical studies. The aim of the study was to evaluate the anxiolytic effect of GB-115 as a tablet form with subchronic oral administration in comparison with phenazepam in nonhuman primates.
Materials And Methods: The study was conducted on four male rhesus monkeys (Macaca mulatta) aged 5.

Background: Primary biliary cholangitis (PBC) is a cholestatic, autoimmune liver disease with the presence of characteristic autoantibodies. The aim of the work was to determine the level of antibodies directed against bacterial antigens: (anti-anti), (anti-), (anti- ) and () in sera of PBC patients. We also performed studies on the impact of the bacterial peptides on the specific antigen-antibody binding.

Objective: To determine the prevalence of amoebiasis, which has been neglected in recent years according to the World Health Organization, in ulcerative colitis patients and investigate the relationship between amoebiasis and ulcerative colitis.
Methods: The study included 150 individuals, including 100 ulcerative colitis patients and 50 healthy individuals without gastrointestinal complaints. The samples collected were first analyzed macroscopically and then using native-Lugol, trichrome staining, and enzyme-linked immunosorbent assay (ELISA).
Plasma adiponectin and biomarker-confirmed Alzheimer's disease in a tertiary memory clinic.

Alzheimer's disease (AD) is associated with early metabolic dysfunction and adiponectin, which may play a pathophysiological role. Adiponectin is implicated in the regulation of energy homeostasis, carbohydrate, and lipid metabolism, as well as in inflammation modulation. The aim of this study was to study whether plasma adiponectin levels were different between patients with AD confirmed by biomarkers and neurological control subjects.

Objective: This study investigates whether urinary cortisol (UC) and UC-to-creatinine ratio (UCCR) perform better than basal serum cortisol (BSC) in identifying dogs with hypoadrenocorticism (HA).
Methods: A retrospective, multicenter study with 120 client-owned dogs included: 20 with HA, 42 healthy, and 60 with diseases mimicking HA. The UC and UCCR were determined on urine samples using a chemiluminescent enzyme immunoassay.
