The fundamental role of the major histocompatibility complex (MHC) in immune recognition has led to a general consensus that the characteristically high levels of functional polymorphism at MHC genes is maintained by balancing selection operating through host-parasite coevolution. However, the actual mechanism by which selection operates is unclear. Two hypotheses have been proposed: overdomina...

Three hundred fifteen crossbred steers (732 ± 9 lb) were used to determine the effects of feeding high levels of Sweet Bran ® during the grain adaptation period on steer performance and carcass characteristics compared with steers fed a steam-flaked corn and alfalfa-based adaptation diet containing 20% Sweet Bran. A traditional step-up procedure was compared to four strategies which utilized Sw...

The effect of cooking methods on some proximate properties of sweet potato (Ipomoea batatas L) was investigated. With the initial properties of the fresh sweet potatoes (sample A) determined, 600g each of samples B, C and D were boiled peeled, boiled unpeeled and roasted unpeeled respectively. The properties determined for the samples are moisture content, ash, fibre, protein, fat, carbohydrate...

INTRODUCTION Sweet syndrome (acute febrile neutrophilic dermatosis) is a subset of rare inflammatory disorders, first described by Dr. Robert Douglas Sweet in 1964 (Sweet, 1964). The co-existence of Sweet syndrome and spontaneous recurrent peritonitis has never been previously mentioned in the medical literature. PRESENTATION OF CASE We report a case of a 37-year old female patient with known...

The fly pharyngeal sense organs lie at the transition between external and internal nutrient-sensing mechanisms. Here we investigate the function of pharyngeal sweet gustatory receptor neurons, demonstrating that they express a subset of the nine previously identified sweet receptors and respond to stimulation with a panel of sweet compounds. We show that pox-neuro (poxn) mutants lacking taste ...

Sweet and umami (the taste of monosodium glutamate) are the main attractive taste modalities in humans. T1Rs are candidate mammalian taste receptors that combine to assemble two heteromeric G-protein-coupled receptor complexes: T1R1+3, an umami sensor, and T1R2+3, a sweet receptor. We now report the behavioral and physiological characterization of T1R1, T1R2, and T1R3 knockout mice. We demonstr...

Currently used tests of Hardy-Weinberg proportions do not take into account the nature of the alternative hypothesis, which is generally a heterozygote deficiency. Different exact tests, appropriate for small sample size and large number of alleles, are proposed in this perspective, and their properties are evaluated by power comparisons. Some tests are found to be close to optimal for the dete...

AIMS To assess Sweet Talk, a text-messaging support system designed to enhance self-efficacy, facilitate uptake of intensive insulin therapy and improve glycaemic control in paediatric patients with Type 1 diabetes. METHODS One hundred and twenty-six patients fulfilled the eligibility criteria; Type 1 diabetes for > 1 year, on conventional insulin therapy, aged 8-18 years. Ninety-two patients...

in order to evaluate intercropping of soybean (glycine max l. cv. jk) with sweet basil (ocimum basilicum l.) and borage (borago officinalis l.) with weed interference, an experiment was performed in randomized complete block design with 12 treatments and three replications at a field located 10 km of shirvan during year of 2011. the treatments were included 75% soybean: 25%sweet basil, 50%soybe...

Morphological studies showed that tree shape in Bitter sweet orange and Yuma citrange was spheroid with spreading growth habit and wide branch angle. Leaves were simple with dark green color, medium size and brevipetiolate in Sour orange while Yuma citrange had trifoliate leaves with medium and green color. Bitter sweet orange had the highest leaf lamina length (10.4 mm) than other rootstocks. ...
