September 20 07 During the 30 minutes it will take you to read this article, 360 preschool children will die of hunger and malnutrition. Twelve a minute, around the clock; more than six million a year. But that is only the tip of the proverbial and ugly iceberg. One in four preschoolers in developing countries suffers from hunger and nutritional deficiencies. These children do not grow to their...

A century ago, malaria was prevalent across much of the inhabited world. With improvements in housing, environmental management, access to antimalarial drugs (quinine, followed by chloroquine), and use of the insecticide DDT, malaria was driven from Europe, North America, and the Union of Soviet Socialist Republics. Building on these early successes, the World Health Organization launched the f...

Background: Black spots are a major problem in commercial shrimp species and can have negative effects on shrimps' appearance, quality, shelf life, economic value, and product acceptance by consumers. This study was conducted to investigate the effect of orange peel extract on chemical and sensory qualities as well as black spots on Litopenaeus vannamei species of white farmed shrimp. Methods: ...

Barn swallows Hirundo rustica have white spots on their tail feathers, and they have been hypothesized to be a handicap because white spots are prone to feather breakage, ectoparasites are disproportionately common in white spots, and size of white spots increases with tail length. Here I test for attractiveness of narrow and long tail spots by manipulation of their shape while using complete p...

abstract background: asterocytoma is the most common primary human brain tumor which has the most lethal hazard among tumors in human central nervous system. heat shock proteins play an active role in cancer cells pathways through their effects on tumor cell proliferation, tumor differentiation, malignancy, metastasis, and cell death. hsp 70 is a 70 kd protein that its expression change has bee...

a 29- year old female with bone pain and history of precocious puberty was referred for bone scintigraphy. on physical examination café au lait macular spots were noted on her neck, buttocks and left leg. bone scan showed multiple areas of intense increased activity which was in favour of polyostotic fibrous dysplasia. considering the presence of polyostotic fibrous dysplasia, precocious pubert...

Fungal spores are continuously deposited on the leaf surfaces by wind impaction, sedimentation and rain wash-out from the atmosphere and splash-dispersal. They reside and act as asymptomatic mutualists, benign commensals or latent pathogens. A slight imbalance in this relation can lead to pathogenic phase of the fungi, resulting in a variety of symptoms on leaves viz. discoloration, blight, soo...

The multi-region hybridization assay (MHAbce) for genotyping HIV-1 subtypes B, C and circulating recombinant form (CRF01_AE) was evaluated on paired plasma and dried blood spots (DBS) collected from 68 HIV-1 infected individuals in Thailand. CRF01_AE was the predominant subtype identified using plasma samples (51/62) and DBS (24/27). There was no discordance in subtype designations between plas...

INTRODUCTIONThis protocol describes a method for concentrating gel bands or spots excised from 1D or 2D acrylamide gels. Several replicate protein bands (or spots) are often required to provide sufficient material for sequencing. In these situations, it is necessary to excise several stained protein bands or spots from the gels and pre-concentrate them prior to electroblotting for amino-termina...
