Pea chloroplastic [alpha]-glucosidase (EC 3.2.1.20) involved in transitory starch degradation was purified to apparent homogeneity by ion exchange, reactive dye, hydroxylapatite, hydrophobic interaction, and gel filtration column chromatography. The native molecular mass and the subunit molecular mass were about 49.1 and 24.4 kD, respectively, suggesting that the enzyme is a homodimer. The enzy...

Objective: The objective of this study was to evaluate αamylase inhibitory and α – glucosidase inhibitory activity of the ethanolic extract of Dioscorea villosa tubers in vitro. Materials and Methods: Different concentrations of the plant extract (1.5, 3, 7, 15.30, 60, 125, 250, 500 and 1000 μg/ml) were prepared in ethanol and subjected to α amylase inhibitory and α Glucosidase inhibitory assay...

BACKGROUND Information about Chronic obstructive pulmonary diseases (COPD)-related health resources allocation in China is very limited. The aim of the study was to explore the distribution of COPD-related health resources allocation among different levels public hospitals (PHs) in Hunan Province of central south China. METHODS We randomly collected data from 57 Public Hospitals (PHs) at 3 di...

The objective of this study was to examine the use of partial exchange transfusion (PET) performed for polycythemia hyperviscosity syndrome (PHS) over time. A retrospective review of 141 infants who received a PET for PHS at Yale-New Haven Hospital between 1986 and 2007 was performed, querying maternal and neonatal medical records. Patient demographics, risk factors for PHS, indications for PET...

Listeriosis is an important food-borne disease that causes high rates of morbidity and mortality. For reasons that are not clear, most large outbreaks of human listeriosis involve Listeria monocytogenes serotype 4b. Relatively little is known about the pathogenesis of listeriosis following gastrointestinal exposure to food-borne disease isolates of L. monocytogenes. In the present study, we inv...

Amygdalin is a cyanogenic diglucoside and constitutes the bitter component in bitter almond (Prunus dulcis). Amygdalin concentration increases in the course of fruit formation. The monoglucoside prunasin is the precursor of amygdalin. Prunasin may be degraded to hydrogen cyanide, glucose, and benzaldehyde by the action of the β-glucosidase prunasin hydrolase (PH) and mandelonitirile lyase or be...

PURPOSE To compare the outcomes between laparoscopic total extraperitoneal (TEP) repair and prolene hernia system (PHS) repair for inguinal hernia. METHODS A retrospective analysis of 237 patients scheduled for laparoscopic TEP or PHS repair of groin hernia from 2005 to 2009 was performed. RESULTS The mean age was 52.3 years in TEP group and 55.7 years in PHS group. Of 119 TEP cases, 98 wer...

BACKGROUND The medicinal importance of a novel plant Olax nana Wall. ex Benth. (family: Olacaceae) was revealed for the first time via HPLC-DAD finger printing, qualitative phytochemical analysis, antioxidant, cholinesterase, and α-glucosidase inhibitory assays. METHODS The crude methanolic extract of O. nana (ON-Cr) was subjected to qualitative phytochemical analysis and HPLC-DAD finger prin...

In the current study, we screened 7 clonal lines from single seed phenotypes of Lamiaceae family for the inhibition of alpha-amylase, alpha-glucosidase and angiotensin converting enzyme (ACE) inhibitory activity. Water extracts of oregano had the highest alpha-glucosidase inhibition activity (93.7%), followed by chocolate mint (85.9%) and lemon balm (83.9%). Sage (78.4 %), and three different c...
