As a continuation of our efforts directed towards the development of natural anti-diabetic cataract agents, gigantol was isolated from Herba dendrobii and was found to inhibit both aldose reductase (AR) and inducible nitric oxide synthase (iNOS) activity, which play a significant role in the development and progression of diabetic cataracts. To improve its bioefficacy and facilitate use as a th...

OBJECTIVE To study the metabolic effect and the variability of the effect elicited by inhalation of 87.2 U insulin powder combined with an absorption enhancer. The metabolic effect was compared with that of 10.2 U regular insulin injected subcutaneously and of 5.5 U regular insulin given intravenously RESEARCH DESIGN AND METHODS In this single-center open euglycemic glucose clamp study 13 hea...

BACKGROUND Universal coverage of long-lasting insecticidal nets (LNs) made from polyester or polyethylene fibres has been adopted as the standard of care to control malaria among at-risk populations. To obtain a WHO recommendation, LNs must undergo prospective monitoring of insecticidal efficacy against mosquito vectors over 3 years of household use. The retention of bioefficacy and physical du...

Lepidopteran pest cause significant loss in quantity and quality of produced many agricultural horticultural crops. Therefore management strategies should aim to reduce their population below threshold level. Though chemical pesticides are recommended for controlling these insect pests, biocontrol agents mostly IPM programme.The most important bio-control agent is the entomopathogenic nematodes...

BACKGROUND: The degree to which the amount of aningested nutrient is absorbed and available to the body is calledbioavailability. OBJECTIVES: Relative effectiveness of herbalmethionine (H-Met®) compared to DL-methionine (DL-Met)was investigated in this experiment. METHODS: Exponentialregression analysis was used to determine bioefficacy of H-Met®based on body weight gain, feed intake and feed c...

Several substances/food baits and admixtures thereof were tested in a perspex trap, treated with insecticide [email protected] mg/cm2. Bioefficacy for housefly trapping was evaluated. Combination of ingredients was found to be more effective than individual ingredients. A combination of some easily available and cheap ingredients were employed for field trials. The admixtures of milk powder, dog b...

In the present study, bioefficacy of spinosad (56.25, 72 and 90 g a.i. ha -1 ) and emamectin benzoate (5, 6.25 and 12.5 g a.i.ha -1 ) was studied in comparison to cypermethrin (50 g a.i. ha -1 ) and selfformulated neem seed extract (5 %). Field experiments were undertaken for two cropping seasons during kharif 2005 and summer 2006. From the study it was found that spinosad afforded moderate con...

The bioefficacy of nine commercial formulations of temephos against Aedes aegypti, Aedes albopictus and Culex quinquefasciatus larvae were evaluated in the laboratory. WHO larval bioassay with operational dosage of temephos at 1 mg/L was performed. The larval mortality was recorded every 5 minutes until complete mortality was achieved. All formulations of temephos exhibited various toxicity lev...

Vitamin A deficiency is a major global public health problem. Among the variety of techniques that are available for assessing human vitamin A status, evaluating the provitamin A nutritional values of foodstuffs and estimating human vitamin A requirements, isotope dilution provides the most accurate estimates. Although the relative expense of isotope dilution restricts its applications, it has ...
