background & objectives: tumor diathesis (td) is defined as granular proteinaceous precipitates on slide surface of cytologic smears. it is found in the background of smears of invasive carcinoma but not in all cases. the aim of present study was to determine the prevalence of td in cervicovaginal smears from patients with uterine cervix carcinoma. methods: cytological smears and histologi...

Chromatographic techniques have led to considerable development in mixture ingredient analysis. With the development of stationary-phase and high-pressure module technologies, new possibilities have emerged for the separation of complex systems whose components are characterised by similar structures and properties. Modern detection systems now allow detection and identification of individual i...

BACKGROUND HPV types vary by country and HIV status. There are no data on the prevalent HPV genotypes from Cameroon. METHODS We conducted a cross-sectional, observational study on 65 Cameroonian women. Samples were sent for HPV genotyping and Thin Prep analyses. RESULTS 41 out of 61 samples tested (67.2%) had HPV subtypes detected. The most common high risk types encountered were: 45 (24.6%...

During the past 25 years, there has been a lot of discussion regarding the preparation techniques used for porcelain veneers. Calamia and other early pioneers looked at veneers as a non-invasive, additive process and worked primarily with a nopreparation concept. Early on it was found that a little enamel preparation could help to enhance the esthetic outcome and improve the marginal fit. Later...

Powder flowability affects dynamic powder behavior during additive manufacturing and varies depending on particle size distribution, morphology, surface features. In this study, Inconel 718 alloy powders were prepared by gas atomization (GA), plasma (PA), rotating electrode process (PREP). The was experimentally evaluated the avalanche angle. With help of numerical simulations, individual effec...

Pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy. There is little scientific consensus about how to measure PrEP program implementation progress. We draw on several years of experience in implementing PrEP programs and propose a PrEP continuum of care that includes: (1) identifying individuals at highest risk for contracting HIV, (2) increasing HIV risk awareness among th...

OBJECTIVES This study was to investigate the prevalence of actual uptake of pre-exposure prophylaxis (PrEP), willingness to use daily oral PrEP under two cost scenarios, and potential issues related to PrEP use among men who have sex with men (MSM) with HIV negative/unknown sero-status in Hong Kong, China. Factors associated with the two measures of willingness were also investigated. METHODS...

BACKGROUND For young South African women at risk for human immunodeficiency virus (HIV) infection, preexposure prophylaxis (PrEP) is one of the few effective prevention options available. Long-acting injectable PrEP, which is in development, may be associated with greater adherence, compared with that for existing standard oral PrEP formulations, but its likely clinical benefits and additional ...
