Department of Biology, Microbiology and Science Laboratory Technology, Faculty of Sciences, Nile University of Nigeria, FCT, Abuja, 900001, Nigeria.
Background: Technological development has led to the wide use of mobile phones. However, the role of the hand-held device in the possible spread of antibiotic-resistant bacterial pathogens considering gender variation, especially among Nigerian undergraduates is poorly understood. This study aimed to assess bacterial isolates recovered from male and female mobile phones for antibiotic resistance and determine possible factors that could facilitate their spread.

Background: Consumer-oriented wearable devices (CWDs) such as smartphones and smartwatches have gained prominence for their ability to detect atrial fibrillation (AF) through proprietary algorithms using electrocardiography or photoplethysmography (PPG)-based digital recordings. Despite numerous individual validation studies, a direct comparison of interdevice performance is lacking.
Objective: This study aimed to evaluate and compare the ability of CWDs to distinguish between sinus rhythm and AF.
Cross-device and test-retest reliability of speech acoustic measurements derived from consumer-grade mobile recording devices.

In recent years, there has been growing interest in remote speech assessment through automated speech acoustic analysis. While the reliability of widely used features has been validated in professional recording settings, it remains unclear how the heterogeneity of consumer-grade recording devices, commonly used in nonclinical settings, impacts the reliability of these measurements. To address this issue, we systematically investigated the cross-device and test-retest reliability of classical speech acoustic measurements in a sample of healthy Chinese adults using consumer-grade equipment across three popular speech tasks: sustained phonation (SP), diadochokinesis (DDK), and picture description (PicD).

Background: Facial prosthetics are an important means to rehabilitate patients with congenital or acquired facial defects. However, with a time-consuming manual workflow and workforce shortage, access to facial prosthetics is limited in Australia and worldwide, especially for rural and remote patients. Optical 3D scanning has been increasingly integrated in digitizing data.

Diazepam (DZP) is a muscle-relaxing, anxiety-relieving sedative drug; nonetheless, it is also an addictive drug that may be abused. This work reports on the development of a novel electrochemical nanosensor for diazepam using SiO-encapsulated-3-mercaptopropionic acid-capped AuZnCeSeS quantum dots (QDs) overcoated with a molecularly imprinted polymer (MIP) on screen-printed carbon electrodes (SPCEs). Electrochemical, spectroscopic and electron microscopic characterization of the nanomaterial and modified electrode surface was carried out and is reported herein.
