Calf milk replacers (MR) commonly contain 40% to 50% lactose. For economic reasons, starch is of interest as a lactose replacer. Compared with lactose, starch digestion is generally low in calves. It is, however, unknown which enzyme limits the rate of starch digestion. The objectives were to determine which enzyme limits starch digestion and to assess the maximum capacity for starch digestion ...

Cistus genus (Cistaceae) comprises several medicinal plants used in traditional medicines to treat several pathological conditions including hyperglycemia. These include Cistus salviifolius L. (CS) and Cistus monspeliensis L. (CM), still not fully explored as a source of metabolites with therapeutic potential for human diseases. In this study, the antioxidant α-amylase and α-glucosidase enzyme ...

The aim of this study was to characterize maize lines tolerant to cold temperatures during the germination process. Seeds from lines with different levels of tolerance to low temperatures were used; 3 lines were classified as tolerant and 3 as susceptible to low germination temperatures. A field was set up to multiply seeds from selected lines. After the seeds were harvested and classified, we ...

Malnutrition affects people of all ages in many countries in the developing world. One treatment for malnutrition is the intervention involving ready-to-use therapeutic foods (RUTFs). This study developed RUTFs for pregnant women in Mali using formulation computer software and largely local, plant-based ingredients. Mali has the world's second highest birth rate and infant mortality rate. Nutri...

Senescence and stresses have been documented to promote ethylene synthesis in ethylene-sensitive flower such as carnations. Thus the inhibition of ethylene evolution might lead to activation of other metabolic reactions. Present experiments were undertaken with cut at bud stage spray-carnation (D. caryophyllus f. spray, Hort.) flowers, cv. Regina and cv. Naslada. Tested cultivars are a new bree...

This study is aimed at assessing the inhibitory effect of teas on key enzymes (α-amylase and α-glucosidase) linked with type-2 diabetes and their antioxidant properties. Four samples of three brands were used; infusions of green tea (GT), 2 brands of black tea (BT), and a formulated herbal preparation for diabetes (ADT) (white tea, Radix Puerariae, Radix ophiopogonis, hawthorn berry, Chinese ya...

Long-term type 2 diabetes can lead to numerous biological complications, such as hypertension and cardio-vascular disease. Key enzymes involved in the enzymatic breakdown of complex carbohydrates,pancreatic alpha-amylase and intestinal alpha-glucosidase, have been targeted as potential avenues for modulation of type 2 diabetes-associated post-prandial hyperglycemia through mild inhibition of th...

BACKGROUND Moringa stenopetala has been used in traditional health systems to treat diabetes mellitus. One of the successful methods to prevent of the onset of diabetes is to control postprandial hyperglycemia by the inhibition of α-glucosidase and pancreatic α-amylase activities, resulting in the aggressive delay of the carbohydrate digestion of absorbable monosaccharides. The aim of the prese...

alpha-amylase e.c.3.2.1.1. (1,4 glucan, 4 glucanohydrolase) can be obtained from salivary glands, pancreas and microorganisms such as pseudomonas and asperigllus, as well as muscles and ovarian tubes.1.2 alpha-amylase from bacillus subtilis #1024(a tcc 465)* was purified with a highest degree of purity in our laboratory (31.59 u/mg). the extracellular alpha-amylase was subjected to different pu...
