BACKGROUND The 24-h respiratory quotient (24-h RQ) and 24-h carbohydrate balance (24-h CHO-Bal) are predictors of weight change. Whether these relations are mediated by the effects of substrate oxidation and balance on food intake is not known. OBJECTIVE We tested whether substrate oxidation and balance predict future ad libitum food intake. DESIGN Substrate oxidation and balance were measu...

Background: Slaughterhouse wastewater (SWW) is hardly treated due to the large amount of organic matter, nutrients and suspended solids. These materials are naturally decomposed through biological processes, and then environmental pollution, transmission of pathogens and problems become smelled. Conventional purification methods require high investment costs, high energy consumption and expert ...

Objective- In the present study the role of essential oil of Salvia rhtidia (SR), in ameliorating renal ischemia reperfusion (IR) injuries is evaluated. Design- Experimental in vivo study. Animals- 48 male healthy Wistar rats between 250-300 grams. Procedures- The animals were randomly divided into eight groups of six rats. In ischemic groups (groups A-D), under general anesthesia b...

OBJECTIVE The most accurate method to estimate Na and K intakes is to determine 24 h urinary excretions of these minerals. However, collecting 24 h urine is burdensome. Therefore it was studied whether spot urine could be used to replace 24 h urine samples. DESIGN Participants collected 24 h urine and kept one voiding sample separate. Na, K and creatinine concentrations were analysed in both ...

BACKGROUND The vitamin D metabolizing enzymes 25-, 1α- and 24-hydroxylase are expressed in malignant cells of the cervix and the ovaries. The aim of this study was to obtain further information about the regulation of the aforementioned enzymes by vitamin D, calcidiol and calcitriol in cervical and ovarian cancer. MATERIALS AND METHODS The human cervical adenocarcinoma cell line HeLa and the ...

One new cycloartane-type saponin, 3-O-[β-D-xylopyranosyl-(1→2)-β-D-xylopyranosyl]-6-O-β-Dglucuronopyranosyl-3β,6α,16β,24(S),25-pentahydroxyxyxloartane (1) was isolated from the MeOH extract of whole plant parts of Astragalus erinaceus along with 5 known saponins (2-6), cyclodissectoside, cycloastragenol, 6-O-β-D-glucopyranosyl-3β,6α,16β,24(S),25-pentahydroxycycloartane, oleifolioside B and 3,6d...

25-Hydroxy-24-oxovitamin D3 (25(OH)24-oxo-D3), a metabolite of 25-hydroxyvitamin D3, has been chemically synthesized. The ultraviolet, mass, infrared, and proton nuclear magnetic resonance spectra of the 25(OH)24-oxo-D3 were identical with those of the natural product isolated from chick kidney incubates. The oxo compound showed biological activity similar to 24,25-dihydroxyvitamin D3 (24,25(OH...
