Laboratory-based CD4 monitoring of HIV patients presents challenges in resource limited settings (RLS) including frequent machine breakdown, poor engineering support and limited cold chain and specimen transport logistics. This study assessed the performance of two CD4 tests designed for use in RLS; the Dynal assay and the Alere PIMA test (PIMA). Accuracy of Dynal and PIMA using venous blood wa...

Plasma and lipoprotein cholesterol and triglyceride concentrations were measured in Pima Indians, a genetically homogeneous population with a high prevalence of obesity and diabetes and a low frequency of coronary heart disease. The data for nondiabetic Pima Indians were compared with those of U.S. Caucasians measured during the Lipid Research Clinics Prevalence Study. Plasma total and low-dens...

BACKGROUND Flow Cytometry (FCM) is still considered to be the method of choice for accurate CD4 enumeration. However, the use of FCM in developing countries is problematic due to their cost and complexity. Lower-cost technologies have been introduced. We evaluated CyFlow Counter together with its lyophilized reagents, and Pima CD4 in high-temperature area, using FACSCount as reference. MATERI...

The objective of this study was to explore the known narrow genetic diversity and discover single-nucleotide polymorphic (SNP) markers for marker-assisted breeding within Pima cotton (Gossypium barbadense L.) leaf transcriptomes. cDNA from 25-day plants of three diverse cotton genotypes [Pima S6 (PS6), Pima S7 (PS7), and Pima 3-79 (P3-79)] was sequenced on Illumina sequencing platform. A total ...

BACKGROUND Point-of-care CD4 testing can provide immediate CD4 reporting at HIV-testing sites. This study evaluated performance of capillary blood sampling using the point-of-care Pima™ CD4 device in representative primary health care clinics doing HIV testing. METHODS Prior to testing, prescribed capillary-sampling and instrument training was undertaken by suppliers across all sites. Matchin...

A 13-year-old neutered male Maltese dog presented to our hospital with lethargy and anorexia. Laboratory abnormalities included severe non-regenerative anemia (hematocrit, 12.9%; reticulocyte count 12.8 K/μL). The cytology of bone marrow revealed erythroid hypercellularity mild myelofibrosis. Therefore, late-stage precursor-targeted immune-mediated (PIMA) was diagnosed. Multimodal treatment inc...

AIMS To determine the intracellular accumulation in a macrophage cell line of ampicillin and ampicillin esters, and to measure their activity against intracellular Listeria monocytogenes. METHODS Quantitative evaluation of the activity of ampicillin, phthalimidomethylampicillin (PIMA) or pivaloyloxymethylampicillin (PIVA) against intracellular L. monocytogenes, and direct measurement of cellu...

Eight Holstein steers (439 kg) with "T" cannulas in the rumen and proximal duodenum were used to evaluate the characteristics of digestion of Pima cottonseed. Treatments consisted of a basal growing-finishing diet containing (DM basis) 1) 15% tapioca, 2) 15% whole linted cottonseed (Delta Pine 61, DP); 3) 15% whole lint-free cottonseed (Pima, PW), and 4) 15% ground Pima cottonseed (PG). Substit...

Pima Indians have served as a model of non-insulin-dependent diabetes mellitus (NIDDM). Within this population, inherited insulin resistance is a primary determinant of abnormal glucose metabolism. The insulin receptor is regarded as a "candidate gene" that could potentially be defective in Pima Indians or other populations with NIDDM. To directly address the question of potential insulin-recep...
