Effects of a Short-Term Vocal Loading Task and Different Restoration Strategies on Voice.

Objective: The purpose of this study is to examine the effects of a short-term (30 minutes) vocal loading task (VLT) on the objective and subjective parameters of voice and determine the restorative strategies of three different vocal exercises performed after the VLT.

Methods: The sample of the study included 30 normophonic women. The protocols that were applied in the study were carried out on three consecutive days.

Thermomechanical properties of confined magnetic nanoparticles in electrospun polyacrylonitrile nanofiber matrix exposed to a magnetic environment: structure, morphology, and stabilization (cyclization).

Electrospun metal oxide-polymer nanofiber composites hold promise for revolutionizing biomedical applications due to their unique combination of electronic and material properties and tailorable functionalities. An investigation into the incorporation of Fe-based nanofillers for optimizing the polyacrylonitrile matrix was conducted, where the systematic and organized arrangement of inorganic components was achieved through non-covalent bonding. These carefully dispersed nanomaterials exhibit the intrinsic electronic characteristics of the polymers and concurrently respond to external magnetic fields.

Autonomic Nerve Function Predicts Risk of Early Death after Discharge in Acute Medical Disease.

Background: Heart rate variability, a marker of autonomic function, has shown promising prognostic results in specific populations, but has not been tested in a general medical population. We hypothesized that heart rate variability identifies high-risk medical patients early after admission to the hospital.

Methods: This was a single-center prospective cohort study of acutely admitted medical patients aged ≥18 years with a life expectancy ≥3 months, included between 2019-2023.

Anticorrosion and Antimicrobial Tannic Acid-Functionalized Ti-Metallic Glass Ribbons for Dental Abutment.

In this study, a recently reported Ti-based metallic glass (MG), without any toxic element, but with a significant amount of metalloid (Si-Ge-B, 18 atom %) and minor soft element (Sn, 2 atom %), was produced in ribbon form using conventional single-roller melt-spinning. The produced TiZrSiGeBSn ribbons were investigated by differential scanning calorimetry and X-ray diffraction to confirm their amorphous structure, and their corrosion properties were further investigated by open-circuit potential and cyclic polarization tests. The ribbon's surface was functionalized by tannic acid, a natural plant-based polyphenol, to enhance its performance in terms of corrosion prevention and antimicrobial efficacy.

A strangulated umbilical hernia with perforated Meckel diverticulum: Case report.

Introduction And Importance: Meckel's diverticulum (MD) is one of the most common gastrointestinal anomalies and affects 2-3 % of the population. Strangulated umbilical hernia with a perforated Meckel diverticulum is an extremely rare event.

Case Presentation: We reported here a case of one year old boy of a strangulated umbilical hernia with perforated MD that operated at the Mogadishu hospital.
