EVALUATION OF THE EFFECTS OF FAVIPIRAVIR (T-705) ON THE LUNG TISSUE OF HEALTY RATS: AN EXPERIMENTAL STUDY.

Favipiravir, a broad-spectrum RNA-dependent RNA polymerase inhibitor widely used during the COVID-19 pandemic, effectively reduces viral load but has been linked to inflammatory changes in tissues such as the liver and kidneys. High-dose and prolonged use of favipiravir for COVID-19 raises concerns about its potential toxic effects on the lungs, particularly in patients with pre-existing pulmonary conditions. This study investigated favipiravir's effects on lung tissue in healthy rats.

Histopathological and Immunohistochemical Evaluation of Methotrexate-Induced Gonadal Damage in Rats: Role of SCF, mTOR, and SIRT-1.

Objective: Methotrexate (MTX) is a highly effective chemotherapy for cancer. This drug has a gonadotoxic effect, mainly in the testes and ovaries. Our study used histopathological and immunohistochemical methods to assess the potential damage to testicular and ovarian tissue caused by MTX use.

Dental Pulp-Derived Mesenchymal Stem Cells Increase Axon Numbers in Mental Nerve Repair.

Aim: The mental nerve, the extended part of the inferior alveolar nerve, is often injured during dentoalveolar, orthognathic, or tumor surgery. Numerous therapeutic interventions, including surgery and pharmacotherapy, have been used to enhance the recovery of nerve injuries. Dental pulp stem cells (DPSCs) represent an easily accessible source of adult stem cells that can be isolated from the pulp of extracted teeth.

Enhanced kidney damage induced by increasing nonylphenol doses: impact on autophagy-related proteins and proinflammatory cytokines in rats.

Nonylphenol (NP) is an organic pollutant and endocrine disruptor chemical that has harmful effects on the environment and living organisms. This study looked at whether kidney tissues subjected to increasing doses of nonylphenol generated alterations in histopathologic, pro-inflammatory, and autophagic markers. Fifty rats were divided into five groups of ten each: group I: healthy group, II: control (corn oil), group III: 25 μl/kg NP, group IV: 50 μl/kg NP, group V: 75 μl/kg NP.

Metaphoric perceptions of individuals with diabetes in Turkey: A content analysis.

Background: The diagnosis of diabetes mellitus adversely impacts the quality of life due to treatment, changes in daily life, functional disability, and emerging complications. Using metaphors to convey perceptions of diseases and life experiences is crucial for understanding healthcare behaviors.

Objective: This study aimed to explore the metaphorical perceptions of "diabetes" and "being a person with diabetes" within a sample group of individuals with diabetes in Turkey.

The effect of different doses of nonylphenol on the blood-testicular barrier integrity, hormone level, and DNA damage in the testes of rats.

Determining the molecular characteristics of the damage caused by NP exposure in the testis is very important for understanding the source of the damage and developing treatment methods accordingly. Therefore, in this study, it is aimed to evaluate the toxic effects that different doses of NP may cause in the testis, including blood-testicular barrier integrity and sperm DNA damage. For this purpose, 50 adult male Wistar albino rats were used in the study.

Investigation of the anti-oxidative and anti-inflammatory effects of melatonin on experimental liver damage by radiation.

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.

Changes in the histopathology and in the proteins related to the MAPK pathway in the brains of rats exposed to pre and postnatal radiofrequency radiation over four generations.

The development of new technologies and industry increases the number and variety of electromagnetic field (EMF) sources. Researcher are increasingly interested in the effects of EMF on brain health. The brain's function is largely dependent on electrical excitability, so it would be expected to be vulnerable to EMF.

Effects of pre and postnatal 2450 MHz continuous wave (CW) radiofrequency radiation on thymus: Four generation exposure.

This study aims to investigate the effects of pre- and postnatal 2450 MHz continuous wave (CW) radiofrequency radiation (RFR) on the thymus of rats spanning four generations. Four groups; sham, irradiated female, irradiated male, irradiated male and female, each consisting of four rats (one male and three females), were created. During the experiment, rats in the exposure groups were whole-body exposed to 2450 MHz CW-RFR for 12 h/day.

Protective effects of melatonin on female rat ovary treated with nonylphenol.

We investigated using histochemistry and immunohistochemistry ovarian damage caused by nonylphenol (NP) and the protective effect of melatonin treatment of NP induced ovarian damage. We used 21 female rats divided randomly into three groups: control, NP and melatonin + NP. Histopathological examination of the ovaries, and counting and classification of follicles were performed using Masson's trichrome staining.

The protective role of melatonin against the effects of different doses of caffeine on the fetus.

Skeletal system and some organs development changes in rat fetuses with 30 and 60 mg/kg caffeine and melatonin's (10 mg/kg) protective role against rat fetuses were investigated. Groups (n = 4) were formed as Control, LDC, HDC, LDC+melatonin, HDC+melatonin and melatonin. Fetuses were taken by cesarean section and stained using dual skeletal staining method and FESEM.

Impact of prenatal exposure to bisphenol A on pregnant rats: Fetal bone development and immunohistochemistry implications.

Background:: Bisphenol A (BPA) is one of the most commonly produced chemicals in the world. BPA is used in products such as food packaging, personal care products, detergents, and plastic bottles. This study was conducted to determine the effect of BPA on fetal bone development.

Experimental investigation of effects of platelet-rich plasma on early phases of orthodontic tooth movement.

Introduction: The aim of this study was to evaluate the effects of platelet-rich plasma on orthodontic tooth movement in rats.

Methods: We divided 48 Wistar male albino rats into 3 groups: control group, platelet-rich plasma group, and platelet-poor plasma group. The rats in all study groups had orthodontic tooth movement of their maxillary right first molars.

Protective effects of curcumin and beta-carotene on cisplatin-induced cardiotoxicity: An experimental rat model.

Objective: Cisplatin (CDDP) has been known to be an effective antineoplastic drug; however, it has a cardiotoxic effect. Curcumin (CMN) and beta-carotene (BC) have been suggested to protect biological systems against CDDP-induced damage. The current study was conducted to evaluate the possible protective roles of CMN and BC on CDDP-induced cardiotoxicity in rat cardiac tissues.
