Introduction: Operating room (OR) efficiency is a key factor in determining surgical healthcare costs. To enable targeted changes for improving OR efficiency, a comprehensive quantification of the underlying sources of variability contributing to OR efficiency is needed. Previous literature has focused on select stages of the OR process or on aggregate process times influencing efficiency.

Serological studies with pseudotyped viruses offer a safer alternative to live SARS-CoV-2 in evaluating neutralizing antibodies, enabling research in standard labs. The SARS-CoV-2 Spike pseudotyped vesicular stomatitis virus (VSV) pseudoviruses were generated using Spike of Wuhan strain and two variants (B.1.

Age-related macular degeneration (AMD) is an eye disorder that can lead to visual impairment in elder patients, and current treatments include repeated injections of monoclonal antibody-based antivascular endothelial growth factor (anti-VEGF) agents. This study investigates the potential of a nanoformulation of a peptide anti-VEGF molecule for neovascular AMD. Anti-VEGF peptide HRHTKQRHTALH (HRH), which has high affinity to VEGF-Fc receptor, was used as the bioactive agent to control neovascularization of the retina.

Objective: Cellular and humoral immunity plays a role in the pathogenesis of vitiligo. T lymphocytes and natural killer cells involved in cellular immunity carry out their cytotoxic activities through perforin/granzyme-dependent granule exocytosis, in which granulysin and cathepsin-L are also involved. The aim of this study was to investigate the possible role of serum granulysin and cathepsin-L in the etiopathogenesis of vitiligo and their association with disease activity and severity.

Objectives: To evaluate the etiology and diagnostic tools for ureteropelvic obstruction in kidney transplant recipients, we investigated the short-term and long-term outcomes of Foley Y-V pyeloplasty.

Materials And Methods: We retrospectively reviewed 10 patients who underwent kidney transplant followed by additional interventions to treat obstructive ureteral pathologies between 2016 and 2020. We enrolled 4 patients who had received intervention to treat ureteropelvic obstruction.

Ocular neovascularization is a hallmark of several sight-threatening diseases, including diabetic retinopathy and age-related macular degeneration. Currently, available treatments are limited and often associated with side effects. Therefore, a novel approach to ocular neovascularization treatment through utilization of polymersomes from self-assembled sphingosine-grafted hyaluronic acid (HA-Sph) amphiphilic polymers is presented.

Introduction: The purpose of our study was to evaluate reliability of 68Ga-labeled prostate-specific membrane antigen positron emission tomography (68Ga-PSMA PET/CT) and identify appropriate SUVmax cutoff values in order to use for diagnosis, especially in patients remained clinically suspicious for prostate cancer (PCa).

Methods: Eighty-four patients applied 68Ga-PSMA PET/CT subsequent to transrectal ultrasound-guided prostate biopsy (TRUS-bx) involved in this study retrospectively. 68Ga-PSMA PET/CT imagings were analyzed by a nuclear medicine physician, and region of interests were drawn manually in prostate diagrams including 6 segments for each patient.

Article Synopsis
  • The study focuses on high ligation of the inferior mesenteric artery in surgeries for low left-sided colon and rectal cancer, aiming to assess how often this technique is used at a particular academic center and its impact on patient outcomes.
  • Out of 169 patients analyzed, 61.5% had high ligation noted in their surgical reports, with 55.6% showing radiographic evidence of the technique, particularly successful in 70.2% of intended cases.
  • Despite the successful implementation of high ligation, there were no significant differences observed in lymph node yield, time to chemotherapy, or recurrence rates, indicating that high ligation may not affect short-term outcomes compared to low ligation.

Hydrodynamic cavitation (HC) is a phase change phenomenon, where energy release in a fluid occurs upon the collapse of bubbles, which form due to the low local pressures. During recent years, due to advances in lab-on-a-chip technologies, HC-on-a-chip (HCOC) and its potential applications have attracted considerable interest. Microfluidic devices enable the performance of controlled experiments by enabling spatial control over the cavitation process and by precisely monitoring its evolution.

Article Synopsis
  • The study aimed to identify dermatological reactions to COVID-19 vaccines in Turkey, focusing on their clinical features and risk factors.
  • It involved 269 patients aged 18 and older who reported skin reactions after vaccination, including demographics and details about the reactions.
  • The most common reactions observed were urticaria, herpes zoster, and maculopapular eruptions, with a significantly higher reaction rate after mRNA vaccines compared to inactivated vaccines.

Purpose: The study aims to investigate first the presence of Syncytin 2 and its receptor, MFSD2, in human sperm, and second whether the expressions of Syncytin 1, Syncytin 2, and their receptors, SLC1A5 and MFSD2, differ between normozoospermic, asthenozoospermic, oligozoospermic, and oligoasthenozoospermic human sperm samples.

Methods: The localization patterns and expression levels of syncytins and their receptors were evaluated in normozoospermic (concentration = 88.9 ± 5.

Unlabelled: Lentivirus and adeno-associated viruses are invaluable tools for biotechnology applications due to their genetic material delivery abilities both in vitro and in vivo. However, their large-scale productions with Good Manufacturing Practices yield low efficiency when adherent and serum dependent HEK293 (Human Embryonic Kidney) cells are used as the host. To increase production efficiency, HEK293 cells are adapted to grow in suspension using commercially available and chemically defined serum-free mediums.
