Dysregulation of Metabolic Peptides in the Gut-Brain Axis Promotes Hyperinsulinemia, Obesity, and Neurodegeneration.

Metabolic peptides can influence metabolic processes and contribute to both inflammatory and/or anti-inflammatory responses. Studies have shown that there are thousands of metabolic peptides, made up of short chains of amino acids, that the human body produces. These peptides are crucial for regulating many different processes like metabolism and cell signaling, as they bind to receptors on various cells.

Dysregulation of Metabolic Peptides Precedes Hyperinsulinemia and Inflammation Following Exposure to Rotenone in Rats.

Rotenone, a naturally occurring compound derived from the roots of tropical plants, is used as a broad-spectrum insecticide, piscicide, and pesticide. It is a classical, high-affinity mitochondrial complex I inhibitor that causes not only oxidative stress, α-synuclein phosphorylation, DJ-1 (Parkinson's disease protein 7) modifications, and inhibition of the ubiquitin-proteasome system but it is also widely considered an environmental contributor to Parkinson's disease (PD). While prodromal symptoms, such as loss of smell, constipation, sleep disorder, anxiety/depression, and the loss of dopaminergic neurons in the substantia nigra of rotenone-treated animals, have been reported, alterations of metabolic hormones and hyperinsulinemia remain largely unknown and need to be investigated.

The mutational spectrum of NRAS gene discovers a novel frameshift mutation (E49R) in Saudi colorectal cancer patients.

Colorectal cancer (CRC) is a major health problem the world face currently and one of the leading causes of death worldwide. CRC is genetically heterogeneous and multiple genetic aberrations may appear on course of the disease throughout patient's lifetime. Genetic biomarkers such as BRAF, KRAS, and NRAS may provide early precision treatment options that are crucial for patient survival and well-being.

Comparison of success rates in early stages of in vitro fertilization (IVF) in women with and without endometriosis.

Endometriosis remains a significant challenge for reproductive-aged women and is frequently associated with infertility. Although in vitro fertilization (IVF) is used to address infertility in women with endometriosis, its effectiveness in this context is still debated, particularly in developing countries such as Indonesia, where IVF remains a major challenge. The aim of this study was to investigate the success rates of early stages of IVF in women with and without endometriosis.
