Increased Oxidative and Nitrative Stress and Decreased Sex Steroid Relaxation in a Vitamin D-Deficient Hyperandrogenic Rodent Model-And a Validation of the Polycystic Ovary Syndrome Model.

Background/objectives: Both hyperandrogenism (HA) and vitamin D deficiency (VDD) can separately lead to impaired vascular reactivity and ovulatory dysfunction in fertile females. The aim was to examine the early interactions of these states in a rat model of PCOS.

Methods: Four-week-old adolescent female rats were divided into four groups: vitamin D (VD)-supplemented ( = 12); VD-supplemented and testosterone-treated ( = 12); VDD- ( = 11) and VDD-and-testosterone-treated ( = 11).

A quick balance assessment tool for all clinical settings: validity and reliability of the Hungarian version of the activities-specific balance confidence scale.

Background: The Activities-specific Balance Confidence Scale was developed for testing the balance confidence of elderly individuals, and it has been used extensively for evaluating various patients. No such scale has been adapted for the Hungarian population.

Objective: To translate and culturally adapt the Activities-specific Balance Confidence Scale and test the reliability and validity of the Hungarian version.
