Vitamin D (VD) is a neuroactive steroid crucial for brain development, function and homeostasis. Its deficiency is associated with numerous brain conditions. As such, VD and its variants are routinely taken by a broad of groups with/without known VD deficiency. In contrast, the harmful effects of VD overdose have been poorly studied. Similarly, the developmental stage-specific VD deficiency and...

Stereoscopic vision mainly relies on binocular horizontal disparity (HD), and its cortical encoding is well established in the foveal representation of the visual field. The role of vertical disparity (VD) is more controversial. Thus far, in the monkey, very few studies have investigated the HD sensitivity beyond 5 degrees of retinal eccentricity and no evidence of a real encoding of VD exists ...

This study was designed to evaluate pharmacokinetics of sulphadimidine   in cockerels fed on subclinical dose of arsenic (100 ppm) in diet and to determine the protective efficacy following simultaneous dietary medication with Piper longum (pipli)   (100 ppm) in a 12-week feeding trial. Pharmacokinetic parameters were determined after single i.v. dose (50 mg/kg) of sulphadimidine ...

BACKGROUND Vitamin D (VD) and estrogen deficiencies impair Ca absorption and bone mineralization, and the relevance of the interaction between these factors has not been fully understood. AIM OF THE STUDY The aim of the present study was to clarify the effects of a nondigestible saccharide, difructose anhydride III (DFAIII), on the interaction of VD and estrogen deficiencies involved in Ca ma...

In the last few years growing evidence highlighted vitamin D (VD) deficiency is one of the several dynamics that associates with increased atherosclerotic cardiovascular (ASCV) diseases. ASCV diseases and erectile dysfunction (ED) share common risk factors such as diabetes mellitus, hypertension, smoking, hyperlipidemia, and a sedentary lifestyle. The aim of this review was to summarize current...

There is accumulating evidence that vitamin D (VD) has important effects besides its well-known role in calcium and bone metabolism. Hypovitaminosis D is associated with cardiovascular disease, the metabolic syndrome, type 2 diabetes mellitus, cancer as well as with increased mortality. Further, VD deficiency is related to depression and impaired cognitive function. Increasing age and elevated ...

OBJECTIVES To study the clinical impact of a very high coronary artery calcium score (CAC >1000) in patients with no known coronary artery disease (CAD) and normal single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI). The secondary aim was to evaluate whether triple vessel disease would support the notion of balanced ischaemia as an underlying mechanism of false...

The pharmacokinetic parameters of ceftazidime, a third generation cephalosporin, were investigated in six buffalo calves after single intravenous (IV) and intramuscular (IM) administration at a dose rate of 10 mg/kg body weight. Ceftazidime concentrations in plasma and urine were determined by microbiological assay. Ceftazidime disposition was best fitted by a two-compartmental and a one-compar...

Summary Background. During the two last decades, the interest in the role of Vitamin D (VD) in allergic disease has increased. Apart from the well-known actions of VD in bone metabolism, recent studies suggested its possible role as an immune-modulator in allergy. Objective. This study, conducted over the Italian territory, evaluated the possible correlations between VD serum level and diagnose...
