Towards Continuous and Ambulatory Blood Pressure Monitoring: Methods for Efficient Data Acquisition for Pulse Transit Time Estimation.

We developed a prototype for measuring physiological data for pulse transit time (PTT) estimation that will be used for ambulatory blood pressure (BP) monitoring. The device is comprised of an embedded system with multimodal sensors that streams high-throughput data to a custom Android application. The primary focus of this paper is on the hardware-software codesign that we developed to address the challenges associated with reliably recording data over Bluetooth on a resource-constrained platform.

Assessment of antimicrobial drug residues in beef in Abuja, the Federal Capital Territory, Nigeria.

Drugs administered to food-producing animals close to the time of slaughter often result in prohibited antimicrobial residues in the animal tissues at slaughter. Evidence based on the Premi® test confirmed the occurrence of antimicrobial drug residues in 89.3% of kidney and urine samples from cattle slaughtered within Abuja town where the residents rely heavily on beef as a source of protein.

Delayed prostate-specific antigen recurrence after radical prostatectomy: how to identify and what are their clinical outcomes?

Objectives: To identify factors that predict delayed (> 5 years) prostate-specific antigen recurrence (PSAR) after radical prostatectomy (RP) and to analyze the associated clinical outcomes.

Methods: A cohort of 4561 men who underwent RP between 1988 and 2008 was retrieved from the Duke University Prostate Center database. Among them, 1207 (26.

The anti-snake venom activities of the methanolic extract of the bulb of Crinum jagus (Amaryllidaceae).

The anti-snake venom activities of the methanolic extract of the bulb of Crinum jagus plant (Amaryllidaceae) were investigated in vitro and in vivo against the venoms of three notable snake species: Echis ocellatus, Bitis arietans and Naja nigricollis. The extract was prepared by cold marceration in 50% methanol at 37 degrees C with intermittent shaking for 48 h. An yield of 12.
