Beverage-Induced Surface Changes in Biomimetic Dental Resin Composite: AFM and Bacterial Analysis.

Objective:  Continuous advancements in composite resin materials have revolutionized and expanded its clinical use, improving its physical and mechanical properties. Attaining and retaining surface texture and gloss are crucial for the long-term durability of the composite resin material. This study investigated the supra-nanospherical filler composite material compared with different composite resin materials immersed in different beverages.

Lumbar spine coronal balance parameters as a predictor of rehabilitation management outcomes in patients with radiculopathy due to lumbar disc herniation: A multicenter prospective case series study.

This prospective consecutive case series was conducted in 5 physiotherapy clinics in the UAE from January 2021-March 2023 to assess coronal lumbar spine radiographic parameters as a predictor of conservative therapy outcomes in patients suffering from low back and leg pain due to lumbar herniated nucleus pulposus (HNP). Ninety patients (mean age 44 yrs., 54 % male) with lumbar HNP underwent conservative therapy.

Optical coherence tomography in multiple sclerosis: A Tunisian tertiary center study.

Purpose: To study retinal layers on OCT in patients with multiple sclerosis (MS) and look for correlations with clinical and electrophysiological characteristics.

Methods: We conducted a cross-sectional study including MS patients aged between 18 and 60 years and a reference group of healthy, age- and gender-matched, control participants. A neurological examination with assessment of disability by the Expanded Disability Status Scale (EDSS), an ophthalmological examination, a spectral-domain OCT, and visual evoked potentials (VEP) were performed.

Detection of clinically relevant antibiotic-resistant bacteria in shared fomites, waste water and municipal solid wastes disposed near residential areas of a Nigerian city.

Studies investigating environmental hotspots of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in Nigeria are limited. This study was designed to assess various environmental sources and commonly touched surfaces as potential carriers of ARB and ARGs with implications for public health. A total of 392 samples, including sewage (36), sludge (36), diapers (20), plastics (20), water sachet polythene bags (20), food wastes (20), soil beneath dump sites (20), and frequently touched surfaces such as restroom floors (80), corridors (24), door handles (56), and room floors and walls (60), were collected and screened for the presence of resistant bacteria carrying genes such as , , , , and .
