Epigallocatechin Gallate Ameliorates Nicotine Withdrawal Conditions-Induced Somatic and Affective Behavior Changes in Mice and Its Molecular Mechanism.

In nicotine withdrawal (NW) conditions, molecular changes, such as increasing corticotropin-releasing factor (CRF) in the amygdala, and melanocortin signaling in the hypothalamus, can occur in the brain, leading to increased feeding behavior and body weight as somatic changes as well as high anxiety-like behavior as an affective changes. Therefore, this research aimed to investigate the effect of epigallocatechin gallate (EGCG), the largest component in green tea, on CRF, pro-opiomelanocortin (POMC), and melanocortin four receptor gene expression in the brain under NW conditions. The 24 Balb/c male mice used were randomly divided into four groups.

Differentiation of osteoblasts: the links between essential transcription factors.

Osteoblasts, cells derived from mesenchymal stem cells (MSCs) in the bone marrow, are cells responsible for bone formation and remodeling. The differentiation of osteoblasts from MSCs is triggered by the expression of specific genes, which are subsequently controlled by pro-osteogenic pathways. Mature osteoblasts then differentiate into osteocytes and are embedded in the bone matrix.

Several studies have reported problems with the use of pain medications in OA, such as the use of a combination of many drugs and their long-term use. Therefore, this study was designed to evaluate the use of pain medications in OA patients.

Overview of therapeutic changes in antiepileptic drugs in adult patients.

Background Previous studies suggest a highly variable response of antiepileptic drugs (AEDs). This may be because the response to AEDs has been changed to sustained period of freedom from seizures. This study was conducted to determine whether therapeutic changes of AEDs in the treatment of seizure would be observable in an Indonesian population.

Attenuation of IL-1ß on the use of glucosamine as an adjuvant in meloxicam treatment in rat models with osteoarthritis.

Background Osteoarthritis (OA) is the most prevalent joint disease and a common cause of joint pain, functional loss, and disability. The severity of this disease is always associated with increased levels of proinflammatory cytokines, which play an important role in cartilage damage, synovitis, and other damage to joint tissues. The discovery that many soluble mediators such as cytokines or prostaglandins can increase the production of matrix metalloproteinases by chondrocytes led to the first steps of an inflammatory state.

Quercetin attenuates acute predator stress exposure-evoked innate fear and behavioral perturbation.

Background Oxidative stress plays a pivotal role in the pathophysiology and pathogenesis of mental diseases, such as depression or anxiety. Psychological stress induced by predatory stimulus is one of the models that explain how induced affective behavior is manifested as a depression-like state. Quercetin is a flavonoid that exhibits potential pharmacological activity on mental diseases.

Development of nonalcoholic fatty liver disease model by high-fat diet in rats.

Background Nonalcoholic fatty liver disease (NAFLD) is indicated by liver steatosis without excessive alcohol use or other liver disease. Several studies have reported that metabolic syndromes such as obesity, type 2 diabetes mellitus, and dyslipidemia have a linear correlation associated with NAFLD pathophysiology.
