rearing methods for bracon hebetor (say) (hym., braconidae) were investigated in the series of laboratory experiments designed to enhance the yield of the mass rearing of this parasitoid for biological control of lepidopteran field and stored product pests. in these experiments, the effects of parasitoid and host densities on fertility and sex ratio of b. hebetor were assessed. in parasitoid de...

OBJECTIVE To determine whether duration and degree of weight gain are differentially associated with diabetes risk in younger versus middle-aged black and white adults. RESEARCH DESIGN AND METHODS We combined data from three cohort studies: Atherosclerosis Risk in Communities (ARIC), Coronary Artery Risk Development in Young Adults (CARDIA), and the Framingham Heart Study. A total of 17,404 p...

We present a dynamical model of web site growth in order to explore the effects of competition among web sites and to determine how they affect the nature of markets. We show that under general conditions, as the competition between sites increases, the model exhibits a sudden transition from a regime in which many sites thrive simultaneously, to a ”winner take all market” in which a few sites ...

T ype 2 diabetes is fourto sixfold more common in the South Asian population of the U.K. than in the indigenous white Caucasian population. A subset of all patients initially diagnosed with type 2 diabetes shows evidence of slowly evolving islet autoimmunity, termed latent autoimmune diabetes in adults (LADA). LADA is characterized by the presence of circulating autoantibodies specific for isle...

BACKGROUND The association of murine asthma with adiposity may be mediated by adiponectin, an anti-inflammatory adipokine with reduced serum concentrations in obese subjects. A study was undertaken to examine whether the serum adiponectin concentration is associated with human asthma and whether it explains the association between adiposity and asthma, particularly in women and in premenopausal...

Background: Central venous catheterization is a procedure that is being performed frequently especially in critical clinical settings. In such conditions, good knowledge of the surface anatomy of venous structures is vital to avoid possible complications which could result in life-threatening situations such as bleeding and pneumothorax. Considering the difference between venous anatomy of chil...
