  • Depending on the definition used, between 3% and 10% of live neonates are small for gestational age (SGA). The definition of SGA requires the following: (1) accurate knowledge of gestational age; (2) accurate measurements at birth of weight, length, and head circumference; (3) a cutoff, which has been variably set at the 10th percentile, 3rd percentile, or at less than 2 standard deviation from the mean, and (4) race and ethnicity-specific growth curve. Consensus statements are needed on the management of growth hormone therapy in SGA children, as well as treatment and long-term health outcomes such as impaired cognitive function, increased risk of adult cardiovascular disease, and type 2 diabetes.

  • Recently, population-based studies of type 2 diabetes patients have provided evidence that metformin treatment is associated with a reduced cancer incidence and mortality, but its mode of action remains unclear. Here we report effects of metformin on hepatocellular carcinoma (HCC) Hep-G2 cells and details of molecular mechanisms of metformin activity. Our research indicates that metformin displays anticancer activity against HCC through inhibition of the mTOR translational pathway in an AMPK-independent manner, leading to G1 arrest in the cell-cycle and subsequent cell apoptosis through the mitochondrion-dependent pathway. Furthermore, we showed that metformin strongly attenuated colony formation and dramatically inhibited Hep-G2 tumor growth in vivo. In conclusion, our studies suggested that metformin might have potential as a cytotoxic drug in the prevention and treatment of HCC.

  • Skeletal muscle insulin resistance, which increases the risk for developing various metabolic diseases, including type 2 diabetes, is a common metabolic disorder in obesity and aging. If potential treatments are to be developed to treat insulin resistance, then it is important to fully understand insulin signaling and glucose metabolism. While recent large-scale "omics" studies have revealed the acetylome to be comparable in size to the phosphorylome, the acetylation of insulin signaling proteins and its functional relevance to insulin-stimulated glucose transport and glucose metabolism is not fully understood. In this Mini Review we discuss the acetylation status of proteins involved in the insulin signaling pathway and review their potential effect on, and relevance to, insulin action in skeletal muscle.

  • Purpose: This study was performed to analyze the trend of foot reflexology research in nursing in Korea. Method: Of studies published in nursing literature between January 1990 and August 2007. The 74 articles were analyzed according to the published year and journal, type of research and study design, subject, and the outcome variables of interventions. Result: Prevailing research designs were experimental research (nonequivalent control group pretest-posttest design). Prevailing characteristics of subjects were patients with hypertension, diabetes mellitus, hemodialysis, cancer and others disease (osteoarthritis, cerebral vascular accident, pneumoconiosis). The most frequently performed intervention was Foot-Reflexo-Massage (FRM). The most frequently used outcome variables were fatigue and sleep. The effect of foot reflexology was inconclusive. Conclusion: The finding suggests that a robust research design in foot reflexology research is needed to accumulate a strong scientific evidence and to adopt nursing intervention from the foot reflexology modalities. Meta analysis of foot reflexology research should be done to analyze and integrate the results of various studies.

  • Disparities in health and disease between various population subgroups, such as racial and ethnic groups, are a major focus of public health research but also pose considerable challenges. Diet is a key contributor to disparities in many chronic diseases and conditions. Therefore, in order to understand and address racial and ethnic health disparities, it is important to characterize the dietary patterns of the populations of interest. African Americans are at higher risk for many diet-related chronic disease conditions, such as obesity, type II diabetes, cardiovascular disease, and many cancers relative to other racial/ethnic groups in the United States. In this report, I describe the diet-related chronic disease profiles of African Americans, characterize their dietary patterns and food preferences, identify demographic, psychosocial, environmental, and cultural factors that may affect their dietary choices, and propose strategies for improving the dietary and health profiles of African Americans.

  • This study examined the effects of the daily administration of high-molecular-weight (HMW) chitosan in drinking water (0.8 %) on kidney function in streptozotocin (STZ)-induced diabetic ICR mice. The HMW chitosan lowered the blood urea nitrogen (BUN), serum and urine creatinine levels, urine protein levels, and albuminuria and reduced the kidney weight in STZ-induced type 1 diabetic ICR mice. On histopathological findings, capillary loops are open, but narrowed, and the mesangial matrix enlarged in the STZ-induced diabetic ICR mice. By contrast, the capillary loops and mesangial matrix of the chitosan-treated ICR mice were nearly normal compared with the STZ-induced diabetic ICR mice.

  • Recently, the incidence of metabolic dysfunction-associated steatotic liver disease (MASLD) is increasing due to the high prevalence of metabolic conditions, such as obesity and type 2 diabetes mellitus. Steatotic liver is a hotspot for cancer metastasis in MASLD. Altered lipid metabolism, a hallmark of MASLD, remodels the tissue microenvironment, making it conducive to the growth of metastatic liver cancer. Tumors exacerbate the dysregulation of hepatic metabolism by releasing extracellular vesicles and particles into the liver. Altered lipid metabolism influences the proliferation, differentiation, and functions of immune cells, contributing to the formation of an immunosuppressive and metastasis-prone liver microenvironment in MASLD. This review discusses the mechanisms by which the steatotic liver promotes liver metastasis progression, focusing on its role in fostering an immunosuppressive microenvironment in MASLD. Furthermore, this review highlights lipid metabolism manipulation strategies for the therapeutic management of metastatic liver cancer.

  • An FDA approved drug for the treatment of type II diabetes, Troglitazone (TRO), a peroxisome proliferator-activated receptor gamma agonist, is withdrawn due to severe idiosyncratic hepatotoxicity. In the search for new applications of TRO, we investigated the cellular effects of TRO on YD15 tongue carcinoma cells. TRO suppressed the growth of YD15 cells in the MTT assay. The inhibition of cell growth was accompanied by the induction of cell cycle arrest at $G_0/G_1$ and apoptosis, which are confirmed by flow cytometry and western blotting. TRO also suppressed the expression of cell cycle proteins such as cyclin D1, cdk2, cdk4, cyclin B1, cdk1(or cdc2), cyclin E1 and cyclin A. The inhibition of cell cycle proteins was coincident with the up-regulation of $p21^{CIP1/WAF1}$ and $p27^{KIP1}$. In addition, TRO induces the activation of caspase-3 and caspase-7, as well as the cleavage of PARP. Further, TRO suppressed the expressions of Bcl-2 without affecting the expressions of Bad and Bax. Overall, our data supports that TRO induces cell cycle arrest and apoptosis on YD15 cells.

  • Purpose: Coronary artery spasm (CAS) and diabetes mellitus (DM) are implicated in endothelial dysfunction, and insulin resistance (IR) is a major etiological cause of type 2 DM. However, the association between CAS and IR in non-diabetic individuals has not been elucidated. The aim of the present study was to evaluate the impact of IR on CAS in patients without DM. Materials and Methods: A total of 330 eligible patients without DM and coronary artery disease who underwent acetylcholine (Ach) provocation test were enrolled in this study. Inclusion criteria included both hemoglobin A1c <6.0% and fasting glucose level <110 mg/dL without type 2 DM. Patients were divided into quartile groups according the level of homeostasis model assessment of insulin resistance (HOMA-IR): 1Q (n=82; HOMA-IR<1.35), 2Q (n=82; $1.35{\leq}HOMA-IR<1.93$), 3Q (n=83; $1.93{\leq}HOMA-IR<2.73$), and 4Q (n=83; $HOMA-IR{\geq}2.73$). Results: In the present study, the higher HOMA-IR group (3Q and 4Q) was older and had higher body mass index, fasting blood glucose, serum insulin, hemoglobin A1c, total cholesterol, and triglyceride levels than the lower HOMA-IR group (1Q). Also, poor IR (3Q and 4Q) was considerably associated with frequent CAS. Compared with Q1, the hazard ratios for Q3 and Q4 were 3.55 (95% CI: 1.79-7.03, p<0.001) and 2.12 (95% CI: 1.07-4.21, p=0.031), respectively, after adjustment of baseline risk confounders. Also, diffuse spasm and accompanying chest pain during Ach test were more strongly associated with IR patients with CAS. Conclusion: HOMA-IR was significantly negatively correlated with reference diameter measured after nitroglycerin and significantly positively correlated with diffuse spasm and chest pain.
