Rationale: End-stage renal disease (ESRD) is characterized by severely impaired renal function that necessitates dialysis or kidney transplantation for patient survival. Integrative Personalized Medicine Care (IPMC), which integrates conventional therapies with Traditional Korean Medicine, has been applied as a complementary approach to address ESRD and its associated complications through a holistic and individualized care model. To our knowledge, this is among the first documented cases evaluating the long-term safety and efficacy of IPMC in a patient with ESRD complicated by intracerebral hemorrhage (ICH).

Obesity is characterized by increased fat mass, as adipose tissue serves as a storage site for excess energy from food consumption. In obesity, altered lipid metabolism of adipose tissue, characterized by fatty acid uptake, de novo lipogenesis, and lipolysis, are induced. In this study, we examined the effect of zerumbone, a major sesquiterpene from wild ginger, on high-fat diet (HF)-induced obesity and dysregulated lipid metabolism in the white adipose tissues (WAT) of C57BL/6N mice.

Article Synopsis
  • The study examined how the remaining corticospinal tract (CST) relates to motor recovery in patients with pontine infarcts, using diffusion tensor imaging (DTI).
  • Significant correlations were found between the ratios of fiber number (FN) and CST area and the patients' motor outcomes after six months.
  • The findings suggest that measuring the remaining CST via DTI soon after a stroke can help predict motor recovery in these patients.

There has been great interest in the browning of fat for the treatment of obesity. Although β-lapachone (BLC) has potential therapeutic effects on obesity, the fat-browning effect and thermogenic capacity of BLC on obesity have never been demonstrated. Here, we showed that BLC stimulated the browning of white adipose tissue (WAT), increased the expression of brown adipocyte-specific genes (e.

Recent studies show that brown rice improves glucose intolerance and potentially the risk of diabetes, although the underlying molecular mechanisms remain unclear. One of the phytochemicals found in high concentration in brown rice is γ-oryzanol (Orz), a group of ferulic acid esters of phytosterols and triterpene alcohols. Here, we found that Orz stimulated differentiation of 3T3-L1 preadipocytes and increased the protein expression of adipogenic marker genes such as peroxisome proliferator-activated receptor gamma (PPAR-γ) and CCAAT/enhanced binding protein alpha (C/EBPα).
