Testicular ischemia-reperfusion (I/R) injury during testicular torsion is strongly influenced by oxidative stress caused by excessive accumulation of unscavenged reactive oxygen species. This study aimed to investigate the effects of intra-peritoneal administration of Mito-TEMPO (MT) on I/R injury in testicular torsion/detorsion (T/D) in mice. Forty-two male mice were divided into seven groups including 1 control and 6 treatment groups (360° T/D, 720° T/D, 360° T/D + 0.

The cooling procedure markedly diminishes the quality of guinea pig () sperms, primarily because their membranes are highly susceptible to this process. This susceptibility triggers the generation of reactive oxygen species and free radicals, ultimately leading to lipid peroxidation in the sperm membrane. Surprisingly, there has been a lack of research on the use of Tris-based extenders to safeguard guinea pig sperm under refrigeration conditions.

MiRNAs: main players of cancer drug resistance target ABC transporters.

Naunyn Schmiedebergs Arch Pharmacol

January 2025

Solid Tumor Research Center, Cellular and Molecular Medicine Research Institute, Urmia University of Medical Sciences, Urmia, Iran.

Chemotherapy remains the cornerstone of cancer treatment; however, its efficacy is frequently compromised by the development of chemoresistance. Multidrug resistance (MDR), characterized by the refractoriness of cancer cells to a wide array of chemotherapeutic agents, presents a significant barrier to achieving successful and sustained cancer remission. One critical factor contributing to this chemoresistance is the overexpression of ATP-binding cassette (ABC) transporters.

Fe, Ni, and Cu doped ceria nanoparticles (CeNPs) were prepared with a simple and one-pot hydrothermal synthesis method. We investigated the chemiluminescence (CL) interaction between these NPs and rhodamine B (Rh B) and found that the highest CL intensity was related to the Rh B- Cu doped CeNPs. We assigned that to the higher catalytic property of Cu doped NPs compared to the others.

WEE1 is a key tyrosine kinase involved in the cell cycle regulation with potent anticancer effects in various cancer types including colorectal cancer. Recent studies have focused on the potential of combinational inhibition of Ataxia Telangiectasia and Rad-3-related protein (ATR) and WEE1 in increasing apoptosis in cancer cells. Therefore, this study investigates the effects of inhibiting WEE1, by employing AZD1775, on colorectal cancer cells' susceptibility to VE-822-induced DNA damage and apoptosis.

Radiation therapy is one of the most effective treatments for approximately 60% of patients with cancer. During radiation exposure, the overproduction of reactive oxygen species (ROS) disrupts the lipid layer of the membrane, leading to subsequent peroxide radical formation. Cimetidine (Cim) and famotidine (Fam) are histamine H2 receptor antagonists (H2 blocker), also known as peptic ulcer drugs, that exert radioprotective effects.

Neurophysiology Research Center, Cellular and Molecular Medicine Research Institute, Urmia University of Medical Sciences, Urmia, Iran. Electronic address:

Brain aging is the leading risk factor for most neurodegenerative diseases and has been linked with high rates of neuron loss. Thus, identifying molecular mechanisms underlying neuron loss and pharmacological modulation may be of great importance for slowing or preventing age-related diseases. Herein, we investigated the roles of miR-92a, Akt, mTOR, and NF-κB in age-associated apoptosis in the hippocampus (a critical structure involved in brain aging) of male rats alone and in combination with prazosin.
