The main symptoms of depression, a chronic mental illness, include sadness, low self-esteem, and a diminished sense of enjoyment in life. Many factors have been suggested to be associated with depression, one of which is low testosterone in men. The serotonin reuptake inhibitor fluoxetine (FLU), used to treat depression, has been reported to potentially have detrimental effects on spermatogenesis in rats after long-term use.

Coronary artery bypass graft (CABG) surgery is one of the main treatment procedures for revascularization. Diagnosing postoperative complications can be difficult. One rare complication is the iatrogenic connection of the graft to the venous system, causing distal ischemia due to an arteriovenous shunt.

The parent is the most critical link and decision-maker between the patient and the healthcare provider in treating many pediatric diseases. This entity is essential for the management of pediatric breast diseases for which the rate of surgical intervention is known to be very low. Although previous publications have emphasized that pediatric breast diseases may cause alarming anxiety in parents, the demographic factors that influence this anxiety have not been investigated.

The primary aim of this study was to explore the impact of diabetes on matrix metalloproteases and tissue inhibitors, crucial factors for successful implantation, and to elucidate the molecular mechanisms that undergo changes in the endometrium and the embryo during diabetic pregnancies. In this investigation, we established a streptozotocin-induced diabetic pregnant rat model. Microarray analysis followed by RT-PCR was utilized to identify gene regions exhibiting expression alterations.

Background An anterior cruciate ligament (ACL) tear is one of the most common sports injuries in the knee region. Currently, anatomical ACL reconstruction with quadrupled hamstring tendon autograft and controlled accelerated rehabilitation is a frequently used treatment approach. This study aims to add to the literature the early and mid-term clinical results of the controlled accelerated rehabilitation program we implemented in our clinic to enable patients to return to their daily activities faster after ACL reconstruction.

The COVID-19 pandemic revealed the need for therapeutic and pharmaceutical molecule development in a short time with different approaches. Although boosting immunological memory by vaccination was the quickest and robust strategy, still medication is required for the immediate treatment of a patient. A popular approach is the mining of new therapeutic molecules.

Background: The aim of our study was to investigate the impact of curfews imposed due to the COVID-19 pandemic on emergency department visits, orthopedic trauma frequencies, and types of trauma.

Methods: In this single-center, retrospective cohort study, a total of 16,242 patients, including 3,020 trauma patients, were admitted to level 1 trauma center emergency department between April-June 2020 and 2021 (curfew group) and between April-June 2018 and 2019 (control group). Patients were separated according to emergency department triage categories and trauma mechanisms, and the changes in the days of curfew were analyzed.

Objectives: Hearing loss has been described in patients with radiographic axial spondyloarthropathies (R-AxSpA) but has not been studied in patients with non-radiographic axial spondyloarthropathies (NR-AxSpA); accordingly, the aim of the study was to compare hearing loss in patients with NR-AxSpA, R-AxSpA, and healthy individuals.

Patients And Methods: This cross-sectional observational study was conducted with 68 participants (30 males, 38 females; mean age: 39.8±7.

  • Adriamycin (ADR), a cancer treatment, harms healthy organs like the testis, prompting a study on its effects on pluripotency in rat testis.
  • Rats were split into three groups: untreated control, cumulative dose ADR, and single dose ADR, with various evaluations conducted for testicular damage and spermatogenic cell marker expressions.
  • Results showed decreased seminiferous tubule diameters, lower expression of key pluripotency markers, and reduced testosterone levels in both ADR-treated groups, indicating ADR's detrimental impact on testicular function and maintenance of pluripotency.

We immobilized the olive leaf extract (OLE) with chitosan nanoparticles (CNPs) by optimizing the effect of various immobilization conditions, and OLE-loaded CNPs (OLE-CNPs) were then elaborately characterized physicochemically by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, dynamic light scattering (DLS), and atomic force microscopy (AFM). Under optimal conditions, CNPs were able to accommodate the OLE with a loading capacity of 97.5%.

This study investigated whether trophoectoderm (TE) biopsy adversely impacts serum β-human chorionic gonadotropin (hCG) level on the 15th day of embryo transfer (ET), delivery week and birthweight, between biopsied and unbiopsied embryo groups, in a cohort of women who delivered a singleton baby, following frozen-thawed ET. All women having had a live birth after blastocyst ETs following frozen ET cycles with preimplantation genetic testing (PGT) were included. A control group was selected among women who had a live birth following single frozen blastocyst transfer without PGT-A at the same period in our clinic One hundred fifteen and 173 cycles with- and without-PGT, respectively, were included.

Unlabelled: As a response to the outbreak of the COVID-19 pandemic, governments around the globe have carried on strict lockdown measures affecting millions of jobs, public life, and the well-being of people. This study examines people's subjective well-being, such as the perception of the economic situation and mental well-being, who made adjustments to cope with the earning losses. We estimate the well-being cost, which is the money required to compensate people because of the reduction in earnings or employment loss and the coping strategy followed to bring their well-being to the levels of those who have not adopted any coping strategy.

Radiotherapy is one of the inevitable treatment approaches for several types of cancer. We aimed to show the protective and therapeutic effects of daily use of melatonin on liver tissues subjected to a single dose of 10 Gy (gamma-ray) total body radiation. Rats were divided into 6 groups, of which 10 were in each: control, sham, melatonin, radiation, radiation+melatonin, and melatonin+radiation.

Article Synopsis
  • Paclitaxel is a common cancer treatment known to harm the male reproductive system, prompting research into ways to mitigate its toxic effects using antioxidants like curcumin.
  • A study involving 40 male rats tested the protective effects of curcumin against paclitaxel-induced testicular damage, comparing different treatment groups (control, curcumin only, paclitaxel only, and a combination of curcumin and paclitaxel).
  • Results showed that curcumin significantly reduced testicular damage and improved testosterone levels in the group receiving both curcumin and paclitaxel, indicating a potential protective role for curcumin in mitigating paclitaxel's adverse effects on the testes.

Background: Taxifolin (TXF) is a flavonoid found abundantly in citrus/onion. Encouraging results on its renoprotective effect have been reported in a limited number of drug-induced nephrotoxicity animal models. The present study aimed to evaluate for the first time the potential renoprotective effects of TXF in a paracetamol (PAR)-induced nephrotoxicity rat model.

Uncovering microscopic hydrophilicity and hydrophobicity at heterogeneous aqueous interfaces is essential as it dictates physico/chemical properties such as wetting, the electrical double layer, and reactivity. Several molecular and spectroscopic descriptors were proposed, but a major limitation is the lack of connections between them. Here, we combine density functional theory-based MD simulations (DFT-MD) and SFG spectroscopy to explore how interfacial water responds in contact with self-assembled monolayers (SAM) of tunable hydrophilicity.

  • This study focused on how TGF-B1-transfected adipose-derived mesenchymal stem cell (AD-MSC) conditional medium (TGF-B1-CM) affects CD44 expression and the behaviors of two breast cancer cell lines: MCF-7 and MDA-MB-231.
  • The researchers treated these cell lines with different media and proteins, analyzing their effects on various biological activities such as cell proliferation, migration, and apoptosis using methods like Western blotting and the Muse Cell Analyzer.
  • Results showed that TGF-B1-CM activated the smad signaling pathway, decreased CD44 expression, increased cell apoptosis, reduced proliferation, and hindered cell migration in
