The ATP binding cassette transporters ABCG5 (G5) and ABCG8 (G8) limit the accumulation of neutral sterols by restricting sterol uptake from the intestine and promoting sterol excretion into bile. Humans and mice lacking G5 and G8 (G5G8-/-) accumulate plant sterols in the blood and tissues. However, despite impaired biliary cholesterol secretion, plasma and liver cholesterol levels are lower in ...
OBJECTIVE To analyze the effects of physical exercise on cartilage histomorphometry in osteoporosis-induced rats subjected to immobilization. METHODS We used 36 Wistar rats that were separated into six groups: G1, G2 and G3 submitted to pseudo-oophorectomy, and G4, G5 and G6 submitted to oophorectomy. After 60 days at rest, G2, G3, G5 and G6 had the right hind limbs immobilized for 15 days, f...
Pigments of food and beverages could affect dental bleaching efficacy. The aim of this investigation was to evaluate color change and mineral loss of tooth enamel as well as the influence of staining solutions normally used by adolescent patients undergoing home bleaching. Initial hardness and baseline color were measured on enamel blocks. Specimens were divided into five groups (n=5): G1 (cont...
This study reports the new functional property of amaranth grain against diet-induced endothelial dysfunction in rabbits. Twenty-seven New Zealand rabbits were fed either a standard diet (SD/G1) or a hypercholesterolemic diet (Hichol) for 28 days. On day 29, the Hichol group was subdivided into four groups and begun receiving the following diets for 21 days: G2: SD + amaranth, G3: Hichol + amar...
In view of the medical, veterinary and economic importance of hydatid disease in India, our study aimed to determine the prevalence and genotypes of Echinococcus present in domestic livestock in India. Out of 21,861 animals examined, cattle were found with the highest prevalence of hydatid cysts (5.10%) followed by buffaloes (3.81%), pigs (0.87%) and sheep (0.075%). Phylogenetic analysis of the...
Loss of the skin barrier facilitates the colonization of underlying tissues with various bacteria, where they form biofilms that protect them from antibiotics and host responses. Such wounds then become chronically infected. Topical antimicrobials are a major component of chronic wound therapy, yet currently available topical antimicrobials vary in their effectiveness on biofilm-forming pathoge...
The aim of this study was to evaluate the influence of techniques of composite resin polymerization and insertion on microleakage and microhardness. One hundred and eighty class II cavities were prepared in bovine teeth and assigned to six groups: G1 - bulk filling + conventional polymerization; G2 - bucco-lingual increments + conventional polymerization; G3 - bulk filling + soft-start polymeri...
در این تحقیق c54h18 و دو لایه آن (c54h18)2 به ترتیب به عنوان مدل گرافن (g1) و گرافن دولایه (g2) انتخاب و نسبت به وارد کردن پیوند پپتیدی در بین دو صفحه گرافن اقدام شد، اما بهینه-سازی هندسی صورت نگرفت. در ادامه به منظور جلوگیری از شکسته شدن پیوند پپتیدی، یک اتم کربن از هر لایه را با اتم si جایگزین و ساختار g3 به دست آمد و پیوند پپتیدی در بین این دو اتمsi قرار گرفت و ساختار g4 بهینه شد. در پایان د...
Objective. Aim to study how the content of alendronate affected shear strengths at bone-bone cement-metal interfaces. Methods. All samples were divided into 6 groups, G0-G5. On the 1st and 60th day after surgery, bone-bone cement interface shear strengths and bone densities were examined. Interface strengths of metal-bone cement specimens were studied before immersion and 4 weeks after immersio...
Here we tested the ability to augment the biological activity of the thrombin aptamer, d(GGTTGGTGTGGTTGG), by using locked nucleic acid (LNA) to influence its G-quadruplex structure. Compared to un-substituted control aptamer, LNA-containing aptamers displayed varying degrees of thrombin inhibition. Aptamers with LNA substituted in either positions G5, T7, or G8 showed decreased thrombin inhibi...
