In the United States, type 2 diabetes mellitus (T2DM) disproportionately affects the African American (AA) community, which has not been systematically included in molecular studies of underlying mechanisms. As part of a gene expression study, we recruited cases with T2DM and matched, unaffected controls at an urban hospital in Washington, DC, with a majority AA population. Here we describe the profile of socio-demographic, behavioral, and health-related associations of the study population. Self-reported data were collected from cases with T2DM (N = 77) and age- and gender-matched controls (N = 80), ages 45 - 65 years. Logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CI). As expected, obesity, hypertension, and cardiovascular disease were more prevalent in cases than in controls. Tobacco smoking and working alongside other tobacco smokers were also associated with T2DM. After adjusting for covariates, current tobacco smoking remained statistically associated with the disease (OR per half pack of cigarettes 1.43, 95% CI 1.04 - 1.95;p-value 0.027). HbA1c levels were elevated in T2DM cases who smoked more than a pack of cigarettes daily. These associations highlight the comorbid burdens of T2DM in an AA urban community setting and identify tobacco control as an unmet need for future prevention and control efforts.

Background: We report a rare case of congenital bilateral testicular agenesis who presented with a suicide attempt. We pose the question of testosterone therapy could improve his mental health. Case Report: A 36-year-old man was admitted to a psychiatric ward after the suicide attempt. An endocrinology consult is requested to address if hormone replacement therapy could improve his depression and future suicide attempts. His past medical history is significant for gonadal agenesis, testicular implants placement at age 16, bipolar type 1 diagnosed 2 years ago before the presentation. The patient received testosterone replacement treatment at age 13 - 15 years. Since that time, he has not been placed on any testosterone therapy. Physical exam revealed minimal axillary and pubic hair, testicular implants with a microphallus. Laboratory values reflect hypergonadotropic hypogonadism consistent with testicular agenesis. He was suicidal and testosterone treatment was deferred. Discussion: It is a rare case of congenital testicular agenesis with bipolar disorder which was resistant to therapy. The patient had profound hypogonadism, which needed testosterone replacement therapy. However, the therapy was deferred because of an acute psychotic condition. This case also highlights that there is no strong evidence of the effect of hormonal therapy on mental health in this group.

The biodegradation of polymeric biocomposites formed from epoxidized linseed oil and various types of fillers(pine needles,pine bark,grain mill waste,rapeseed cake)and a control sample without filler was studied during 180 days of exposure to two types of forest soil:deciduous and *** weight loss,morphological,and structural changes of polymer composites were noticed after 180 days of the soil burial *** greatest weight loss of all tested samples was observed in coniferous forest soil(41.8%–63.2%),while in deciduous forest soil,it ranged between 37.7%and 42.3%.The most significant changes in the intensities of the signals evaluated by attenuated total reflectance infrared spectroscopy,as well as morphological changes determined by scanning electron microscopy,were assessed for polymer composite with rapeseed cake and specimen without filler in coniferous forest soil and are in a good agreement with weight loss *** significantly lower changes in weight loss,morphology,and structure of polymeric film with pine bark were noticed in both *** was suggested that fungi of Trichoderma,Penicillium,Talaromyces and Clonostachys genera are the possible soil microorganisms that degrade linseed oil-based cross-linked polymer ***,the novel polymer composites have the potential to be an environmentally friendly alternative to petroleum-based mulching films.

Proof of retrievability (POR) is a technique for ensuring the integrity of data in outsourced storage *** this paper,we address the construction of POR protocol on the standard model of interactive proof *** propose the first interactive POR scheme to prevent the fraudulence of prover and the leakage of verified *** also give full proofs of soundness and zero-knowledge properties by constructing a polynomial-time rewindable knowledge extractor under the computational Diffie-Hellman *** particular,the verification process of this scheme requires a low,constant amount of overhead,which minimizes communication complexity.
