Regulation of Neuropeptide Y Receptor Gene Expression and Hormone Level in Obese Male Rats Receiving 6-Gingerol and L-Arginine Supplementation.

Obesity and its associated disorders, such as hyperlipidemia, have become a global issue following the consumption of unhealthy, high-fat, and high- carbohydrate foods, which burdens the economies and the health systems of human societies worldwide. This study aimed to evaluate the effect of oral consumption of 6-gingerol and L-arginine supplements on obesity factors. Thirty rats in five groups were fed a diet specific to each group for 12 weeks and then treated with the oral administration of L-arginine (200 mg/day) and 6-gingerol (100 mg/day) for 12 weeks. The food and water intake and weight change, were then measured. In addition, plasma glucose, triglyceride, cholesterol, high-density lipoprotein (HDL), very-low-density lipoprotein (VLDL) , low-density lipoprotein (LDL), and serum hormone levels, including corticosterone, testosterone, and insulin, were measured, and NPY, Y1, and Y5 receptor gene expression were recorded using real-time PCR. Administration of 6-gingerol and L-arginine decreased food intake, weight gain, glucose levels, insulin levels, and homeostasis model assessment-insulin resistance (HOMA-IR) index compared to the HCD control group. In addition, corticosterone and testosterone levels in the study groups showed a significant decrease (P<0.05) and increase (P<0.01) compared to the control groups, respectively. Triglyceride, total cholesterol, HDL, and VLDL levels in the groups treated with L-arginine and gingerol alone or combined significantly decreased compared to the control group (P<0.01). This study confirms that 6-gingerol and L-arginine supplements prevent HCD-induced hyperlipidemia by controlling hormones and neurotransmitters involved in the general metabolism. .

Comparison of the Performance of Bioresonance, Electrophoresis and RT-PCR in the Diagnosis of Feline Infectious Peritonitis.

Feline infectious peritonitis (FIP) continues to be one of the most researched infectious diseases of cats. The diagnosis of FIP is challenging, and diverse techniques have been developed for its accurate diagnosis. However, they have some limitations. The present study was conducted to investigate the efficacy of specific modulation frequency (SMF), compared to other routine diagnostic methods for detecting feline coronavirus. Blood samples were collected from 30 diseased cats suspected of having FIP based on clinical signs. Electrophoresis, polymerase chain reaction (PCR), and SMF tests were performed for each sample. The sensitivity and specificity of each test, as well as the agreement between the tests and the gold standard (the combination of PCR, electrophoresis, and bioresonance results), were calculated using the Kappa coefficient method. The sensitivity and specificity of electrophoresis, PCR, and SMF for the diagnosis of FIP were 70.6%, 70.6%, 100%, and 100%, 72.7%, 81.8%, respectively. According to the findings of the present study, SMF is effective and safe in FIP diagnosis, which is a challenge in veterinary medicine diagnosis.
