Background: Many sperm characteristics including, motility and morphology are important for normal spermatozoa- oocyte intraction. These features may be altered during vitrification. Motile sperm organelle morphology examination (MSOME) is an unstained real time high magnification technique that analysis viable sperm morphology instantly. This study aimed to investigate the influence of vitrifi...

The oxidation o i low-density lipoprotein (LDL) by macrophages. smooth muscle cells antl enclothelial cells. within the vessel wall. may play a central role in the development of atherosclerotic lesions[ I]. Proposed mechanism of cell-mediated oxidation. include attack by lipoxygenases[2] or generatiori of supcroxide[3] but these mechanisms have proved controversial[4.5]. Nitric oxide protects ...

BACKGROUND A cryopreservation protocol for human amnion-derived mesenchymal stem cells (HAMs) is required because these cells cannot survive for long periods in culture. The aim of this study was to determine whether vitrification is a useful freezing method for storage of HAMs. METHODS HAMs were cryopreserved using vitrification method. The morphology and viability of thawed HAMs was evaluat...

It was examined whether the physiological effects of high-amylose maize starch (HAMS) are influenced by hydroxypropylation. Rats were fed one of the following three diets: an AIN-93-based diet with waxy maize starch (WMS) as a starch source, or this diet with 150 g of WMS replaced by either HAMS or hydroxypropylated HAMS (HP-HAMS). The activities of amylase in bile-pancreatic juice and sucrose,...

The aim of this study was to investigate the sensory characteristics of dry-cured hams from confined Iberian pigs fed on a high oleic (HO) concentrate (HO-Pienso hams), and to study how different the characteristics of these hams are from those of Iberian hams from the best grade (Montanera hams, from extensively reared pigs). Nearly half of the fatty acids studied were similar in HO-Pienso and...

OBJECTIVE African-American/Black and Latino/Hispanic persons living with HIV/AIDS (i.e., "PLHA of color") are under-represented in HIV/AIDS medical studies (HAMS). A crucial entry point into HAMS is screening, but PLHA of color face serious barriers to screening compared to Whites. Recently we evaluated a social/behavioral intervention that substantially increased rates of HAMS screening among ...

Objectives were to test the effect of a lowsodium curing solution on processing characteristics of hams from purebred Berkshire pigs that were fed a step-up ractopamine HCl (RAC) feeding program or a negative control diet. Sixty pairs (n = 120) of hams were selected from two blocks of purebred Berkshire pigs (n = 200) that were fed either a control diet or 7.4 mg of ractopamine/ kg of diet for ...
