The test consisted of a study of pollen supplements and vitamins in the diet of honey bee (Apis mellifera L.) colonies in the drought seasons of 2001 and 2002 in northern Iraq. The impact of five different kinds of food on the hypopharyngeal gland of 8-day-old workers, and the area of brood in the nests was examined. The results showed that in 2001 bees fed with vitamin C had an acini of hypoph...

The use of dexamethasone (Dex) to treat chronic lung disease in preterm infants may produce adverse effects in the developing brain. Here, we evaluated the effects of neonatal Dex on the propagation of cortical spreading depression (CSD), and tested the action of vitamins C and E against the effect of Dex. Five groups of Wistar rats received, respectively: [1] no treatment (Naïve); [2] Vehicle ...

Vitamins are often added to fish diets at levels above those required for normal growth. Fortification of diets in this manner may be done for a variety of reasons. Certain physiological processes or conditions such as reproduction, stress, or disease may increase the levels of vitamins needed by the fish to maintain normal growth, metabolism, and health. Certain vitamins, such as vitamin E, ma...

Objective(s) Oxidized low-density lipoproteins (ox-LDLs) appear to play a significant role in atherogenesis. In fact, circulating ox-LDL concentrations have been recognized as a risk factor for cardiovascular disease (CVD). The main objectives of this study were to assess the effects of antioxidant vitamins on ox-LDL as a biomarker of CVD in male subjects with CVD risk factors. Materials and ...

Vitamins are essential substances which are required in small amounts in the body on a regular basis for normal health and various physiological functions in the human body. They are widely distributed in natural food sources and can be easily introduced into the diets to satisfy daily needs. Though vitamins are a group of organic compounds that have different structural and chemical properties...

BACKGROUND AND AIM Trace elements and vitamins play a vital role in human body to perform its function properly. Thalassemic patients are at risk of micronutrient deficiency. This study estimated levels of vitamins A, C, E, B12, folic acid, total homocysteine (tHcy), and methylmalonic acid (MMA) along with trace elements, zinc, copper, and selenium in Beta-thalassemia-major patients. METHODS ...

A tremendous amount of information was published over the past decades in relation to the role of vitamins in various neoplastic diseases. In particular, several studies showed an inverse relationship between selected vitamins intake and cancer risk. In this review we will focus on the role played by vitamins in melanoma with particular regard to vitamin A, D, K, E and C. Given that vitamin sup...

INTRODUCTION We assessed whether co-supplementation of vitamins C and E has additive beneficial effects on reducing the kidney damage and attenuation of the arterial pressure elevation compared to administration of either vitamin C or vitamin E alone in deoxycorticosterone acetate-salt-induced hypertension. MATERIALS AND METHODS Forty rats were divided into 4 study groups and 1 sham-operated ...

Introduction. We assessed whether cosupplementation of vitamins C and E has additive beneficial effects on reducing the kidney damage and attenuation of the arterial pressure elevation compared to administration of either vitamin C or vitamin E alone in deoxycorticosterone acetate-salt-induced hypertension. Materials and Methods. Forty rats were divided into 4 study groups and 1 sham-operated g...
