Transcription factors are involved in cell cycle and apoptosis regulation and thus have a key role in the carcinogenesis of different tumors. Nuclear factor of activated T-cells, cytoplasmic 2 (NFATc2) and peroxisome proliferator-activated receptor gamma (PPARG) transcription factors are important in the carcinogenesis of colorectal cancer (CRC). In this study, we examined whether the expression of NFATc2 and PPARG genes is significantly altered during the carcinogenesis of CRC. A total of 47 tumor samples and matched normal tissue margins were collected during surgery from patients with CRC...

Testicular cancer is a relatively rare tumor type, accounting for approximately 1% of all cancers in men. However, among men aged between 15 and 40 years, testicular cancer is the most commonly diagnosed malignancy. Testicular germ cell tumors (TGCTs) are classified as seminoma and non-seminoma. The RAS oncogene controls several cellular functions, including cell proliferation, apoptosis, migration, and differentiation. Thus, RAS signaling is important for normal germ cell development. Mutations of the Kirsten RAS (K-RAS) gene are present in over 20% of all cancers...

The pendulum test is a method applied to measure passive resistance of the knee. A new and simple pendulum test with instrumentation based on infrared camera was used to evaluate knee stiffness and viscosity on a female human cadaver. The stiffness and viscosity were calculated based on the kinetic data. During the measurements, the periarticular and intraarticular soft tissue of the knee was gradually removed to determine the stiffness and viscosity as a function of the tissue removal rate. The measurements showed that the removal of tissue around the joint reduces the damping of leg oscillation, and therefore decreases the stiffness and viscosity...

Type 1 diabetes mellitus (T1DM) results from autoimmune destruction of pancreatic β-cells after an asymptomatic period over years. Insulitis activates antigen presenting cells, which trigger activating CD4+ helper-T cells, releasing chemokines/cytokines. Cytokines activate CD8+ cytotoxic -T cells, which lead to β-cell destruction. Apoptosis pathway consists of extrinsic (receptor-mediated) and intrinsic (mitochondria-driven) pathway. Extrinsic pathway includes Fas pathway to CD4+-CD8+ interaction, whereas intrinsic pathway includes mitochondria-driven pathway at a balance between pro-apoptotic B-cell lymphoma (Bcl) 2 and Bcl-xL and anti-apoptotic Bad, Bid, and Bik proteins...
