Abstract
Triple-negative breast cancers (TNBCs) are associated with poor survival mediated by treatment resistance. TNBCs are fibrotic, yet little is known regarding how the extracellular matrix (ECM) evolves following therapy and whether it impacts treatment response. Analysis revealed that while primary untreated TNBCs are surrounded by a rigid stromal microenvironment, chemotherapy-resistant residual tumors inhabit a softer niche. TNBC organoid cultures and xenograft studies showed that organoids interacting with soft ECM exhibit striking resistance to chemotherapy, ionizing radiation, and death receptor ligand TRAIL. A stiff ECM enhanced proapoptotic JNK activity to sensitize cells to treatment, whereas a soft ECM promoted treatment resistance by elevating NF-κB activity and compromising JNK activity. Treatment-resistant residual TNBCs residing within soft stroma had elevated activated NF-κB levels, and disengaging NF-κB activity sensitized tumors in a soft matrix to therapy. Thus, the biophysical properties of the ECM modify treatment response, and agents that modulate stiffness-dependent NF-κB or JNK activity could enhance therapeutic efficacy in patients with TNBC.

Abstract
OBJECTIVE To investigate the effect of blood serum concentration of cotinine among non-smokers, passive/light smokers and active smoker females in the United States population as it compares to vitamin D blood serum concentrations. MATERIALS AND METHODS National Health and Nutrition Examination Survey (NHANES) that is designed to assess the health and nutritional status of adults and children in the United States by Centers for Disease Control and Prevention (n=22,196). RESULTS The analyses demonstrated that among all three smoking categories, black female active smokers have lower vitamin D (13.374 ng/ml), than hispanic (19.213 ng/ml) or white (24.929 ng/ml) females. It was demonstrated that the active smoker black females have the highest percentage of vitamin D deficiency and inadequacy in the population compared to other ethnic females. CONCLUSION The cotinine blood serum concentrations can also affect vitamin D concentrations in addition to other factors such as gender, ethnicity, dietary supplement intake and sun exposure.

Abstract
OBJECTIVES Insulin resistance in diabetes mellitus type 2 (DM2) can result from membrane lipid alterations. Blacks are at a higher risk of developing DM2; therefore, we investigated whether membrane lipid differences exist between blacks and whites and if differences contribute to impaired insulin binding in diabetes. METHODS Subjects were recruited from four groups: white control (n = 10), black control (n = 10), white diabetic (n = 5), and black diabetic (n = 10). Diabetic subjects who had DM2 with insulin resistance on insulin monotherapy were matched by age and sex. The following determinations were made: fasting serum glucose, fasting serum insulin, plasma lipid profile, red blood cell (RBC) membrane lipids and cholesterol, and RBC insulin binding. RESULTS The membrane lipid analysis showed racial differences in phosphatidyl ethanolamine (PE) and phosphatidyl choline (PC). The plasma membrane of whites showed higher PE and lower PC levels than that in blacks. The RBC rheologic (PE/phosphatidyl serine) properties (deformability) were lower in diabetics and black subjects. The saturated nature of RBC ([sphingomyelin + PC)/(PE + phosphatidyl serine]) was the lowest in white control subjects (P < 0.056). CONCLUSION The combination of increased saturated/polyunsaturated fatty acids, increased saturated nature, and increased cholesterol/phospholipid can contribute to decreased membrane fluidity, resulting in insulin resistance. Also, decreased RBC deformability can make oxygen delivery through the capillaries difficult, create tissue hypoxia, and contribute to some of the known complications of diabetes. Membrane lipid alteration may be one of the reasons for a higher incidence of diabetes among blacks.

Abstract
OBJECTIVE Central obesity is implicated in the development of insulin resistance by increasing insulin demand and eventually leading to hyperinsulinemia. Anthropometric measurements have been helpful in determining the risk factors in developing diabetes mellitus type 2. In this study we investigated whether anthropometric measurements differ among diabetics of different races. We also evaluated whether nutrient intake of these individuals was related to anthropometric measurement changes. METHODS Subjects were recruited from four groups: white control (n = 10), black control (n = 10), white diabetic (n = 5), and black diabetic (n = 10). The diabetic subjects had type 2 diabetes with insulin resistance on insulin monotherapy (age and sex matched). The following determinations were made: diet analysis, body mass index (kg/m(2)), the ratio of waist (umbilical level) to hip (maximum at buttocks) circumference, the ratio of waist to thigh (mid-thigh), and body fat percentage. RESULTS The micronutrient consumption was fairly similar in all groups with the exception of vitamin A (greatest consumption in the white control group, P < 0.05; and the lowest consumption in the black control group, P < 0.05). The data also suggested that central obesity (greatest waist-to-hip ratio) was present in the individuals with type 2 diabetes. The higher total fat, including saturated, monounsaturated, polyunsaturated, and cholesterol, intake in the diabetic groups were observed. CONCLUSION The type of fat consumed may be as important as the total fat consumption in the development of insulin resistance. The diet analysis can provide valuable information about the dietary habits of an individual and the possible causes of metabolic problems leading to a disease state. However, genetic factors must be considered when looking at diabetes incidence in different ethnic groups. For example, even though the black diabetic group consumed less fat in comparison with the other groups, their body fat percentages were higher. Therefore, we cannot conclude that high fat intake is primarily responsible for increased body fat percentage. Although anthropometric measurements are a useful tool in risk assessment, researchers should consider anatomic differences among different racial groups as covariables. Diet analysis when used in conjunction with anthropometric measurements can serve as a useful tool to detect whether metabolic alterations are related to dietary habits.
