The cyst wall of Entamoeba invadens (Ei), a model for the human pathogen Entamoeba histolytica, is composed of fibrils of chitin and three chitin-binding lectins called Jacob, Jessie3, and chitinase. Here we show chitin, which was detected with wheat germ agglutinin, is made in secretory vesicles prior to its deposition on the surface of encysting Ei. Jacob(More)
BACKGROUND There is a significant increase in survival for HIV-infected children who have early access to diagnosis and treatment. The goal of this multi-country review was to examine when and where HIV-exposed infants and children are being diagnosed, and whether the EID service is being maximally utilized to improve health outcomes for HIV-exposed(More)
In this paper, we present a fully integrated lab-on-a-chip and associated instrument for the detection of bacteria from liquid samples. The system conducts bacterial lysis, nucleic acid isolation and concentration, polymerase chain reaction (PCR), and end-point fluorescent detection. To enable truly low-cost manufacture of the single-use disposable chip, we(More)
Green tea is particularly rich in health-promoting flavonoids (which account for 30% of the dry weight of a leaf), including catechins and their derivatives. The most abundant catechin in green tea is epigallocatechin-3-gallate, which is thought to play a pivotal role in the green tea's anticancer and antioxidant effects. Catechins should be considered(More)
BACKGROUND Deficiency of Co-Q10 has been found to be responsible for periodontal destruction; therefore, this study was undertaken to evaluate the anti-gingivitis effect of Co-Q10 on plaque induced gingivitis. MATERIALS AND METHODS Thirty subjects with plaque induced gingivitis were enrolled in a split mouth randomized controlled trial. For each subject,(More)
Various plastic procedures are done to enhance esthetics, relieve hypersensitivity or even prevent root caries. The most predictable plastic procedure is the coronally advanced flap procedure, with subepithelial connective tissue. Owing to the second surgical donor site and difficulty in procuring a sufficient graft in multiple recessions, various(More)
BACKGROUND Children with tuberculosis often have underlying nutritional deficiencies. Multivitamin supplementation has been proposed as a means to enhance the health of these children; however, the efficacy of such an intervention has not been examined adequately. METHODS 255 children, aged six weeks to five years, with tuberculosis were randomized to(More)
BACKGROUND To evaluate variations in fibrin network patterns of the platelet-rich fibrin (PRF) in different age groups. MATERIALS AND METHODS Ninety-five patients were divided into three age groups: Group 1: (20-39 years); Group 2: (40-59 years); and Group 3: (60 years and above). PRF was prepared from blood samples of all patients and were subjected to(More)
Mucoepidermoid carcinomas (MECs) of minor salivary gland origin are rare in children and adolescents and have been reported rarely. Literature regarding their clinical features and biologic behavior is scanty. The purpose of this case report is to discuss the clinical manifestation, diagnosis, and treatment plan of MEC of the palate. A 16-year-old male(More)
Gingival recession is a common manifestation in most populations. Gingival recession is clinically manifested by an apical displacement of the gingival tissues, leading to root surface exposure. Gingival recession may be a concern for patients for a number of reasons such as root hypersensitivity, erosion, root caries, and esthetics (Wennstrom 1996).(More)
