The role of a variety of compounds including organic acids, vitamins, growth promoting substances, purines and pyrimidines in the bioconversion of cortisol with Bacillus cereus was investigated. The transformation of cortisol to prednisolone and pregn-4-en-11beta, 17alpha,20beta, 21-tetrol-3-one was affected by these compounds in different manners. The enzymatic delta1-dehydrogenation reaction was greatly induced with fumarate, menadione, and xanthine treatments. However, the enzymic reduction of the 20-carbonyl to the 20beta-ol was specifically stimulated with fumarate, nicotinic acid amide, and uracil treatments.

Purpose: We hypothesised that the biological heterogeneity of sepsis may highlight sepsis subtypes with differences in response to intravenous vitamin C treatment in the Lessening Organ Dysfunction with VITamin C (LOVIT) trial. Our aims were to identify sepsis subtypes and to test whether sepsis subtypes have differences in treatment effect to vitamin C and describe putative biological effects of vitamin C treatment.
Methods: We measured biomarkers of inflammation, at baseline and at 7 days post-randomisation, in 457/863 (53.

Background: In the face of inevitable declines in alertness and fatigue resulting from sleep deprivation, effective countermeasures are essential for maintaining performance. External trigeminal nerve stimulation (eTNS) presents a potential avenue for regulating alertness by activating the locus coeruleus and reticular activating system.
Methods: Here, we conducted a within-subject study with 66 habitual nappers, subjecting them to afternoon nap-deprivation and applying either 20-minute of 120 Hz eTNS or sham stimulation.
Objective: Aim: To improve the early diagnosis, course, prediction of the development of Acute Respiratory pathology in children, taking into account the state of antioxidant system (AOS).
Patients And Methods: Materials and Methods: The research group included school-age children (10-14 years old) with Acute Respiratory pathologe (n=111) and a control group (n=25).diseases in comparation.
