Background And Objectives: The pediatric population worldwide bears a significant morbidity and death burden due to acute respiratory infections (ARIs). Human Orthopneumovirus, sometimes referred to as the Human Respiratory Syncytial Virus (HRSV), is one of the main causes of ARIs in infants. The main goal of this study was to identify the genetic diversity of HRSV strains that were circulating in the Iranian population at a certain time of year.
Materials And Methods: Two hundred youngsters less than 12 years old with acute respiratory infections had samples taken from their throat and pharynx secretions. Then, external and hemi-nested PCR were employed, using specific primers targeting the G gene region to detect HRSV. Subsequently, nine randomly selected positive samples were subjected to sequencing. The results were then compared with reference strains cataloged in GeneBank, and phylogenetic tree was constructed using Chromes and MEGA7.
Results: Out of 200 samples, 34 were identified as containing HRSV. Subgroup A was predominant, accounting for 61.76% of cases, followed by subgroup BA (35.29%) and subgroup B (2.94%). Phylogenetic analysis revealed five samples associated with subtype B and four with genotype A. Genomic analysis showed three samples under the GA2 subgroup and one under GA1 for subtype A, and four samples in subgroup BA and one in GB2 for subtype B.
Conclusion: In this study, subgroup A strains, particularly genotype GA2, exhibited a higher prevalence compared to subgroup B strains during the specific period under investigation, shedding light on the genetic landscape of HRSV in this region.

Background: Transdermal buprenorphine is used for the management of postoperative pain. Its effectiveness for the postoperative pain management following mandibular resection and reconstruction has yet to be evaluated.
Purpose: To evaluate the efficacy of transdermal buprenorphine patch (TBP) in managing postoperative pain after mandibular resection and reconstruction with anterior iliac crest graft.

With the increasing use of lithium-ion batteries, the exposure and health effects of lithium nickel manganate cobalt (NMC), a popular cathode material for the battery, have attracted widespread attention. However, the main absorption routes and target organs of NMC are unknown. This study aims to systematically investigate the main absorption routes and target organs of NMC.

Background: No previous studies have compared respiratory clinics and respiratory specialized facilities regarding causative diseases for bloody sputum and hemoptysis in Japan.
Methods: We retrospectively compared causative diseases for bloody sputum and hemoptysis between 3 respiratory clinics (clinic group) and 7 departments of respiratory medicine at hospitals (hospital group) in Japan.
Results: We collected data from 231 patients (median age, 51 years; age range, 24-96 years; 109 men (47.
