background: nontypeable haemophilus influenzae (nthi) is a common cause of respiratory tract disease and initiates infection by colonization in nasopharynx. the haemophilus influenzae (h. influenzae) hap adhesin is an auto transporter protein that promotes initial interaction with human epithelial cells. hap protein contains a 110 kda internal passenger domain called “haps” and a 45 kda c-termi...
Standardization of toxin preparations derived from Bacillus thuringiensis (Berliner) used in laboratory bioassays is critical for accurately assessing possible changes in the susceptibility of field populations of target pests. Different methods were evaluated to quantify Cry1Ab, the toxin expressed by 80% of the commercially available transgenic maize that targets the European corn borer, Ostr...
PURPOSE To determine the natural history of collagen crosslinking (CXL)-associated corneal haze measured by Scheimpflug imagery and slitlamp biomicroscopy in patients with keratoconus or ectasia after laser in situ keratomileusis. SETTING Cornea and refractive surgery subpecialty practice, United States. DESIGN Prospective randomized controlled clinical trial. METHODS The treatment group ...
introduction: this study was conducted to evaluate prevalence and risk factors for diagnostic discordance for osteoporosis due to different t-scores of lumbar spine and femoral neck. methods: in this cross sectional study demographic, anthropometric and risk factors for osteoporosis were derived from a database on 3,039 post-menopausal women who underwent bone densitometry for the first time i...
OBJECTIVE To evaluate copper sulphate densitometry to screen for childhood anaemia in a primary care setting, with a view to identifying children requiring definitive diagnostic testing and treatment. DESIGN A cross-sectional screening study. Results of densitometry with a copper sulphate solution of specific gravity (SG) 1.048, corresponding to a haemoglobin (Hb) concentration of 10 g/dl, we...
Context Quantitative standardization of plant-based products is challenging albeit essential to maintain their quality. Aims This study aims to develop and validate high-performance thin-layer chromatography (HPTLC) method for the simultaneous determination of rutin (Ru), quercetin (Qu), and gallic acid (Ga) from Psidium guajava Linn. (PG) and Aegle marmelos (L.) Correa. (AM) and correlate wi...
Abstract Bamboo tableware became popular as ecofriendly material. However, industrial products made of bamboo-melamine–formaldehyde resin material are not biodegradable. In addition, harmful compounds were detected if such consumer articles used with hot drinks or food, and risk assessment found that maximum daily dosages melamine formaldehyde exceeded. High-performance thin-layer chromatograph...
In order to assess the importance of glycosphingolipids (GSL) in the immunology of the platelet, serum antibody binding to immobilized, purified platelet GSLs have been quantitatively measured via high-performance thin-layer chromatography (HPTLC), 125I-radio-immunolabeling, autoradiography, and densitometry. Thirteen neutral GSL bands were detected at Rf.03 through .64 (CHCl3-CH3OH-H2O, 65:25:...
in the developing countries of tropical regions, mycotic infections are common cause of skin diseases.the use of medicinal plants in the treatment of skin diseases including mycotic infections is an age-old practice in many parts of the world. the drugs used against dermatophytosis have several side effects, but limited efficacy. there is therefore a distinct need for discovery of new, safer an...
