Introduction: Genetic diversity in the killer immunoglobulin-like receptor (KIR) gene composition and human leukocyte antigen (HLA) class I ligands, such as HLA-C, can affect the activity of natural killer cells and determine anti-cancer immunity. Specific combinations can enhance cancer predisposition by promoting immune evasion. Studying the relationship between polymorphisms and thyroid cancer (TC) risk can offer insights into how natural immunity fails, leading to disease development.

We present this case of mesodermal mesenchymal polyp in a young female arising at the hymenal ring of the vagina making the introitus very wide. We highlighted in our case the importance of recognizing mesenchymal lesions and their differential diagnosis to provide the patients with optimal care.

However, Dox-induced cardiotoxicity limits the drug's clinical applications. Hence, this study intended to investigate whether diosmin could prevent or limit Dox-induced cardiotoxicity in an animal setting.

Among oropharyngeal squamous cell carcinoma (OPSCC) cancers, tonsillar squamous cell carcinoma (TSCC) is the most prevalent and has a particularly aggressive clinical course with poor disease outcomes. The tumor microenvironment (TME) of HNSCC is complex and heterogeneous, playing a crucial role in effective cancer therapy.

The goal of this study was to evaluate the role of the SGLT2 inhibitor dapagliflozin (DAPA) in the attenuation of lipopolysaccharide (LPS)-induced hypotension. Male Wistar albino rats were divided into normal and diabetic groups and received DAPA (1 mg/kg/day) for two weeks followed by a single dose of 10 mg/kg LPS.

Gefitinib (GEF) is an inhibitor of the epidermal growth factor receptor, linked to higher risk of severe/fatal interstitial lung disease (ILD). This study was performed to determine the protective roles of an angiotensin-II type-1 receptor (AT1R) "valsartan (VAL)" in prevention of lung inflammation, oxidative stress and metabolites alteration induced by GEF. Four groups of male Wistar albino rats were received vehicle, VAL (30 mg/kg), GEF (30 mg/kg), or both for four weeks.

Gefitinib is a tyrosine kinase inhibitor (TKI) of the epidermal growth factor receptor (EGFR), used for the treatment of advanced or metastatic non-small cell lung cancer. Recently, studies proved that Gefitinib-induced cardiotoxicity through induction of oxidative stress leads to cardiac hypertrophy. The current study was conducted to understand the mechanisms underlying gefitinib-induced cardiac hypertrophy through studying the roles of angiotensin II (AngII), oxidative stress, and mitogen-activated protein kinase (MAPK) pathway.

Venetoclax (VTX) is a promising novel agent that has been proven to have a high efficacy in multiple hematological diseases, especially acute myeloid leukemia (AML) and chronic lymphocytic leukemia (CLL). Considering its mechanism of action, the possibility that VTX may cause cardiotoxicity cannot be ruled out.

When this endometrial tissue grows and sheds, symptoms will develop. The presentation varies depending on the site involved; however, cyclical pain is among its most common symptoms, along with bleeding and cramping.

Because their histology is benign, the prognosis for patients is good. We report the case of a patient with a huge ovarian leiomyoma who presented to the General Surgery Clinic with chronic abdominal pain and progressive abdominal distention.

However, recent reports have associated sorafenib with hepatotoxicity that can limit its clinical application, although the mechanism of hepatotoxicity is still to be elucidated. Thus, our study was designed to explore the molecular mechanisms underlying sorafenib-induced hepatotoxicity in an model.

Lacking any characteristic clinical or radiological features, often leading to preoperative misdiagnosis, it is only diagnosed confidently on the basis of histopathology; for this reason combined with the rarity, angioleiomyoma would not be usually found at the top of the differential diagnosis list. Local excision is usually curative with excellent prognosis.
