As reported by Miller (1958c), A4iller and Stone (1962), and Miller and Roy (1963), the North American species D~osophila athnbnsca Sturtevant and Dobzhanslty, 1936, shows intraspecific variation in size and shape of the Y chronlosome. Three categories, designated Types 1, 2, and 3, were recognized. Type 1 is a large, J-shaped Y such as was originally found in this and other D. affinis subgroup species (Sturtevant and Dobzl~anslty, 1936). Type 2 is a medium-sized near-V. Type 3 is a large V-shaped Y ...

New Centers for Disease Control and Prevention (CDC) guidelines recommend routine HIV screening in locations including emergency departments. This study evaluates a novel approach to HIV counseling and testing (C&T) in a high-volume inner-city emergency department in terms of the number of patients who can be recruited, tested, test positive, and are linked to care. This prospective evaluation was conducted for 26 months. Noncritically ill or injured patients presenting to an inner-city emergency ...

In Brief Objective: Many of the individuals most at risk for HIV infection (i.e., minority populations, women, adolescents) are also the most marginalized by our health care system. Lacking primary care providers, they rely on the Emergency Department (ED) for their health care needs and education. In this prospective randomized controlled trial, we compared the educational effectiveness of a 15-minute posttest counseling video with the normal practice of a session with an HIV counselor. The study ...

This research focuses on detection of bi-allelic insertion/deletion polymorphisms (InDels) from challenged samples using the Investigator DIPplex® Kit from Qiagen. The study included analyzing body fluids from humans, as well as pristine and degraded samples. For the purpose of assessing species specificity, samples from various animals were included. At first, an analytical threshold (AT) for the detection of alleles was established based on an assessment of the noise in the system. Then, InDel profiles ...

The goal of this research was to quantitatively measure the amount of salivary amylase in a sample by using UVVIS and the SALIgAE® reagent. The samples included serial dilutions of standard human salivary amylase, human saliva, as well as other body fluids from human and animals. These were added to the SALIgAE® reagent and the absorbances of the solutions were monitored by the UV-VIS at 403 nm every 30 seconds over a 10 minute period. The lowest concentration of salivary amylase detected by UV- ...

Host genetic factors may influence the course of human immunodeficiency virus (HIV) infection. In Blantyre, Malawi, polymerase chain reaction was used to identify twin pairs who were concordantly HIV-1-infected in utero or perinatally and then to examine strain divergence or virus levels in identical and fraternal twin pairs. Among 315 twin pairs, both infants in 14 fraternal and 5 identical pairs were found to be infected at the same visit. Among 10 pairs, HIV-1 sequences were determined for both ...

The social environment in the Bronx, NY, has led to HIV infection rates among young people that are much higher than the national average.A prospective observational study on a convenience sample of medically stable emergency department (ED) patients was conducted from October 1, 2005, to August 31, 2012. Acceptability of the tested model was determined by assessing the number of patients tested and identified HIV infections. Data were compared with data from the rest of the ED that tested for HIV. ...

A genetic locus D1S80 (pMCT 118) containing variable number of tandem repeats (VNTR) has been used extensively in forensic analysis and paternity testing. In the current research, DNA was isolated from blood saliva and nasal secretions collected on two types of IsoCode paper-based devices. The D1S80 locus was amplified using PCR technology, and the alleles were separated by gel electrophoresis and then detected using an infrared (IR) fluorescence automated DNA sequencer. IR-labeled amplification products ...

DNA profiles were generated via direct amplification from blood and saliva samples deposited on various types of swab substrates. Each of the six non-FTA substrates used in this research was punched with a Harris 1.2 mm puncher. After 0.1 μL of blood or 0.5 μL saliva, samples were deposited on each of these punches, samples were pretreated with one of four buffers and washing reagents. Amplification was performed using direct and nondirect autosomal and Y-STR kits. Autosomal and Y-STR profiles were ...

Abstract Cognitive tests sensitive to the integrity of the medial temporal lobe (MTL), such as mnemonic discrimination of perceptually similar stimuli, may be useful early markers of risk for cognitive decline in older populations. Perceptual discrimination of stimuli with overlapping features also relies on MTL, but remains relatively unexplored in this context. We assessed mnemonic discrimination in two test formats (Forced Choice, Yes/No) and perceptual discrimination of objects and scenes in 111 community- ...

Lymphoma is a condition that is difficult to diagnose, and accurate diagnosis is critical for effective treatment. Manual microscopic analysis of blood cells requires the involvement of medical experts, whose precision is dependent on their abilities, and it takes time. This paper describes a content-based image retrieval system that uses deep learning-based feature extraction and a traditional ...
