Understanding mutations and co-mutations in non-small cell lung carcinoma (NSCLC) is critical to developing personalized treatment strategies. Therefore, this study aims to investigate mutations and the accompanying somatic variations in NSCLC. This retrospective study included 98 patients over 18 years of age who were diagnosed with NSCLC, operated on, and referred to the Molecular Pathology Laboratory between January 2019 and June 2024 for next-generation sequencing panel tests and FISH analysis.

Introduction: Absence of mismatch repair (MMR) genes in tumor cells or errors in the replication repair process may lead to DNA-MMR deficiency and microsatellite instability (MSI) formation. Specific tumor environments where gene variations are observed are believed to be conducive to the formation of MSI. This study aimed to determine the MSI status, MMR protein expression, and somatic mutation profile in solid organ tumors.

Background: The co-occurrence of lung adenocarcinoma and brain metastasis remains a significant cause of morbidity and mortality despite advancements in cancer treatment. The activity of neurofibromin, the product of Neurofibromatosis Type 1 gene (NF1), is crucial in regulating the RAS/MAPK pathway. The NF1 somatic mutations are significant in conditions such as melanoma, lung cancer, breast cancer, neuroblastoma, and central nervous system tumors.

Article Synopsis
  • The study aimed to explore the effects of arbutin on colitis, comparing it with mesalazine, a common treatment for inflammatory bowel disease, and examining their combined impact.
  • Forty male Wistar rats were divided into groups to assess inflammation and oxidative stress indicators, as well as histopathological changes in the colon.
  • Results showed that both arbutin alone and in combination with mesalazine significantly reduced inflammation and mucosal damage in the colitis model compared to untreated controls.

Background: The primary tumor and it's metastases show heterogeneity in molecular studies for targeted therapies in Non-Small Cell Lung Cancer(NSCLC), the leading cause of cancer-related deaths worldwide. The study aimed to identify somatic mutations in biopsies from NSCLC patients' metastatic organs using Next-Generation Sequencing(NGS) and examine their association with clinicopathological parameters.

Materials And Methods: The study included 128 NSCLC patients and, NGS was performed on tumor biopsies from different metastatic organs at Molecular Pathology laboratory of the Department of Medical Pathology in Aydın Adnan Menderes University Faculty of Medicine.

Menopausal status affects the prognoses and consequences of breast cancer. Therefore, this retrospective study aimed to reveal the molecular variation profile differences in breast cancer patients according to their menopausal status, with the hypothesis that the molecular variation profiles will be different at premenopausal and postmenopausal ages. Breast cancer patients ( = 254) who underwent molecular subtyping and QIAseq Human Breast Cancer NGS Panel screening between 2018 and 2022 were evaluated retrospectively.

Background/aims: Recent studies that reveal the molecular profiles of colorectal carcinomas have demonstrated tumor heterogeneity. Characterization of colorectal carcinoma-specific genomic alterations is essential for developing more successful and targeted treat- ment protocols. Moreover, it is vital in elucidating the pathogenesis and mechanisms of resistance against treatment and predicting prognosis.

Microscopic polyangiitis is an important and common component of cytoplasmic antibody-associated vasculitides that can lead to serious morbidity and even death. A clear causative etiology has not been identified. Although silica is well known to produce lung damage, the negative renal effects of silica exposure should not be overlooked.

Chronic lymphocytic leukemia (CLL) is a hematological disease characterized by the proliferation of monoclonal B-lymphocytes. Although autoimmune complications such as autoimmune hemolytic anemia and immune thrombocytopenia are common in CLL patients, nonhematological autoimmune complications are rather rare. The most common renal involvements are membranoproliferative glomerulonephritis and minimal change disease.

Background: Lung cancer is the most common cancer type worldwide, with non-small cell lung cancer being the most frequently studied. Identifying of cancer-related genes in non-small cell lung cancer is crucial for developing individualized treatment, particularly as mutation profiles can vary by country and ethnicity.

Aims: To identify comprehensive mutation profiles in a cohort of Turkish patients with non-small cell lung cancer using the next-generation sequencing.

Introduction: Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are acute onset syndromes affecting the lungs, which develop for several reasons and are characterized by hypoxemia and diffuse lung infiltration. The activity of thymoquinone (TQ) is known in acute lung injury. It is considered that it could be effective in ALI/ARDS treatment by ensuring possible COX-2 inhibition.

Objectives: To comparatively evaluate the effects of thymoquinone (TQ), the biologically active main component of volatile oil derived from seeds, in an experimental dry eye model.

Materials And Methods: A total of 36 BALB/c mice 10 weeks of age were used in the study. The mice were divided into 6 groups of 6 mice.

Objectives: To investigate the correlation between tumor stage, Ki-67, Bcl-2, hypoxia inducible factor-1α (HIF-1α), cyclin D1 and metabolic tumor volume (MTV), total lesion glycolysis (TLG), maximum standardized uptake value (SUV) measured by F fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) in patients diagnosed with laryngeal cancer.

Patients And Methods: In this study, included 25 consecutive laryngeal cancer patients (2 women, 23 men) diagnosed and treated in the Otorhinolaryngology Department of our tertiary care center. All cases underwent F FDG PET/CT and SUV, mean standardized uptake value, MTV, and TLG values were calculated.

Background: Ulcerative colitis (UC) is a chronic, inflammatory bowel diseases characterized by uncontrolled inflammatory condition of the colon and rectal mucosa marked by recurrent periods of remission and exacerbation. Vitamin D receptor (VDR) is a member of the steroid receptor family that mediates the effects of vitamin D by regulating transcription of multiple cellular genes. We aimed to evaluate vitamin d receptor level in biopsy specimen of patients with UC in this study.

Background: This study aims to investigate the effect of ozone on myocardial ischemia-reperfusion injury occurring after occlusion - reperfusion of infrarenal abdominal aorta in rats.

Methods: Thirty-two Wistar albino rats (weighing 200-250 g) were randomized into four equal groups. The control (sham) group underwent laparotomy and dissection of the infrarenal abdominal aorta without occlusion.

Objectives/hypothesis: Eosinophilic chronic rhinosinusitis (eCRS) has recently been recognized as a CRS subtype characterized by inflammation rather than chronic infection. Consequently, the role of antibiotics as a component of maximal medical therapy for eCRS has been called into question. The purpose of this study was to investigate whether the use of antibiotics, which lack any secondary anti-inflammatory properties, are useful in the treatment of eCRS.

Colorectal cancer (CRC) is the third most frequent malignancy. Many factors such as NF-κB, matrix metalloproteinase-1 (MMP-1), p53, and Ki-67 are likely to be involved in its development and progression. Lymph node metastases indicate increased tumor burden and tumor cell heterogeneity and affect both the treatment strategies and the prognosis.

Acinic cell carcinoma accounts for approximately 2 to 6% of all salivary gland tumors. It usually originates in the parotid gland; the minor salivary glands and the upper respiratory tract are involved only infrequently. We describe a case of acinic cell carcinoma of the posterior wall of the pharynx in a 21-year-old woman.
