Insights into the pressure-dependent physical properties of cubic CaMF (M = As and Sb): First-principles calculations.

Here, first-principles calculations have been employed to make a comparative study on structural, mechanical, electronic, and optical properties of new CaMF (M = As and Sb) photovoltaic compounds under pressure. The findings disclose that these two systems possess a direct band gap, showcasing a large tunable range under pressure, effectively encompassing the visible light spectrum. Adjusting various levels of hydrostatic pressure has effectively tuned both the band alignment and the effective masses of electrons and holes.

Parental Awareness of Antibiotic Use for Upper Respiratory Tract Infection in Children in Jazan Region, Saudi Arabia.

Background: Upper respiratory tract infections are a prevalent cause of morbidity in children, often managed in primary care settings. These infections are predominantly viral, but antibiotics are sometimes inappropriately prescribed. This misuse, driven by parental pressure and misconceptions, contributes to the growing problem of antibiotic resistance.

Local Anesthetic Infiltration for Pain Control in Aesthetic Breast Reduction Surgery: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Background: Aesthetic breast surgeries, including breast reduction, are commonly performed surgical procedures associated with postoperative pain. Pain control is essential to patient comfort, satisfaction, and early recovery. This systematic review is the first to conduct both qualitative and quantitative analysis to evaluate the efficacy and safety of local anesthetic infiltration in reducing pain after breast reduction surgeries.

Snake Venom: A Promising Source of Neurotoxins Targeting Voltage-Gated Potassium Channels.

The venom derived from various sources of snakes represents a vast collection of predominantly protein-based toxins that exhibit a wide range of biological actions, including but not limited to inflammation, pain, cytotoxicity, cardiotoxicity, and neurotoxicity. The venom of a particular snake species is composed of several toxins, while the venoms of around 600 venomous snake species collectively encompass a substantial reservoir of pharmacologically intriguing compounds. Despite extensive research efforts, a significant portion of snake venoms remains uncharacterized.

The Benefits of Friendships in Academic Settings: A Systematic Review and Meta-Analysis.

Friendships can positively impact students' academic performance and grade point average (GPA) by providing emotional support and reducing stress, thereby leading to improved focus and better concentration on studies. Peer connections and friendships often result in collaborative learning and the exchange of academic ideas, improving comprehension and retention of course materials, ultimately leading to higher GPAs. In contrast, negative friendships or excessive social distractions can adversely affect GPA, which highlights the importance of striking a fine balance between social connections and academic responsibilities.
