Several studies conducted around the world showed substantial vitamin D insufficiency and deficiency among different population groups. Sources of in human body include ultraviolet B (UVB)-light-induced biosynthesis dietary intake, but people’s diets are often poor D. Furthermore, many regions, sun exposure intensity UVB irradiation during wintertime not sufficient for biosynthesis. In Slovenia, epidemiological data about status were investigated through a national Nutrihealth study—an...

Measurement of cardiac troponin in serum is an essential part diagnosing myocardial infarction the emergency department. The guidelines suggest that high-sensitivity techniques should be used for measuring I (cTnI) or T (cTnT). aim our study was to correlate values both troponins, and ascertain which type more agreement with diagnosis. patients were classified into four groups: 43 non-ST-elevation (NSTEMI), 7 ST-elevation (STEMI), 48 Type 2 infarction, 21 control group.

Autism spectrum disorder (ASD) has been associated with disruptions in tryptophan (TRP) metabolism, affecting the production of key neuroactive metabolites. Investigating these metabolic pathways could yield valuable biomarkers for ASD severity and progression. We included 44 children healthy children, members same family. The average age group was 10.7 years, while control 9.4 years. Urinary metabolites were quantified via liquid chromatography-mass spectrometry operating multiple reaction...
