PURPOSE: We assessed whether (1) dapagliflozin (Dapa, an SGLT2-inhibitor) attenuates the deterioration of heart function Nlrp3 and inflammasome activation in diabetic mice. (2) The effects can be augmented with saxagliptin (Saxa), a DDP4-inhibitor. (3) Dapa effect is possibly SGLT2-independent on cardiofibroblasts in vitro. METHODS: Type 2 diabetic (BTBR ob/ob) and wild-type (WT) mice received vehicle, Dapa, or Dapa+Saxa for 8 weeks. Glucose tolerance test and echocardiogram were performed...

BACKGROUND: Traumatic lesions of the olecranon bursa (OB) and prepatellar bursa (PB) are injuries commonly seen in orthopaedic trauma units. These injuries are associated with a high rate of complications. At present, only little is known about the incidence, complication rate, and treatment approaches in patients with acute open bursae. MATERIALS AND METHODS: A total of 552 patients who had been treated for acute traumatic lesions of either the olecranon bursa or the prepatellar bursa, or both at our department were retrospective identified in the years between 2009 and 2014...

REVIEW
Masahiro Yamaguchi
Understanding of the olfactory neural circuits has progressed beyond analysis of how odor information from the external environment is processed in the brain. While spatially-organized sub-circuits were found to exist up to the olfactory bulb (OB), the arrangement in the olfactory cortex (OC), especially in its representative piriform cortex (PC), appears diffuse and dispersed. An emerging view is that the activity of OC neurons may not simply encode odor identity but rather encode plastic odor information such as odor value...

The analysis of nutritional status is anthropologically important to address the complex interaction of biological, social, political, economic and cultural factors. To deepen the knowledge about contexts of occurrence of child malnutrition, we analyzed nutritional status in relation to socio-environmental conditions of residence in children between three and six years from Villaguay, Entre Ríos, Argentina. We performed a cross-sectional study of 1,435 school children of both sexes. Body weight and height were measured and prevalence of low height/age (LH/A), low weight/age (LW/A), low BMI/age (LBMI/A), overweight (Ow) and obesity (Ob) was calculated using World Health Organization reference charts...

Activation of AMP-activated protein kinase (AMPK) could efficiently protect osteoblasts from dexamethasone (Dex). Here, we aim to induce AMPK activation through miRNA-mediated downregulating its phosphatase, protein phosphatase 2A (PP2A). We discovered that microRNA-429 ("miR-429") targets the catalytic subunit of PP2A (PP2A-c). Significantly, expression of miR-429 downregulated PP2A-c and activated AMPK (p-AMPKα1 Thr172) in human osteoblastic cells (OB-6 and hFOB1.19 lines). Remarkably, miR-429 expression alleviated Dex-induced osteoblastic cell death and apoptosis...

By making use of the changes in optical properties such as absorption and dispersion around the resonance generated via electromagnetically induced transparency (EIT), we theoretically and experimentally investigate a "∞"-shape optical bistability (OB) versus frequency on the probe transmission with a Λ-shape EIT window in a rubidium atomic ensemble confined in a three-mirror optical ring cavity. Compared to the traditional OB reflected by a hysteresis loop versus power, such newly demonstrated optical bistable behavior (represented by a "∞"-shape non-overlapping region) by scanning probe and cavity detuning can experience dual bistabilities and be more sensitive to the change of experimental parameters...

The emergence of oligoclonal bands (OB) in patients with multiple myeloma achieving a complete remission (CR) after autologous stem cell transplantation (ASCT) and the use of novel agents is a well-recognized event. The presence of OB is associated with favorable outcome. However, the emergence of OB in light-chain (AL) amyloidosis has never been investigated. The aim of the study was to determine the incidence, natural history and prognostic impact of OB in 50 patients with AL amyloidosis who achieved at least a partial response (PR) either after up-front ASCT (20 patients [40%]) or after conventional treatment in patients ineligible for transplant (30 patients [60%])...

Endometriosis has significant implications on patient health and well-being, particularly when it comes to pelvic pain and infertility. However, the true epidemiologic state of the disease has remained elusive. Many of the foundational studies characterize surgically confirmed endometriosis in highly selected patient populations. It has been hypothesized that the prevalence of endometriosis is approximately 10% (Vigano et al, Best Practices and Research in Clinical OB/GYN, 2004, 18(2):177-200) of reproductive aged women and may reach rates of 30-50% in symptomatic women...

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder and the most common cause of female infertility. However, the etiology of the disease and the mechanisms by which this disorder progress remain unclear. Here we report that a transgenic obese mouse (Mito-Ob) developed by overexpressing prohibitin in adipocytes develops polycystic ovaries. Initially, the female Mito-Ob mice were equally fertile to their wild-type littermates. Mito-Ob mice begin to gain weight after puberty, become significantly obese between 3-6 months of age, and roughly 25% of them become infertile by 9 months of age...

BACKGROUND: Workplaces today demand graduates who are prepared with field-specific knowledge, advanced social skills, problem-solving skills, and integration capabilities. Meeting these goals with didactic learning (DL) is becoming increasingly difficult. Enhanced training methods that would better prepare tomorrow's graduates must be more engaging and game-like, such as feedback based e-learning or simulation-based training, while saving time. Empirical evidence regarding the effectiveness of advanced learning methods is lacking...

Leptin, critical in regulation of energy metabolism, is also important for normal bone growth, maturation and turnover. Compared to wild type (WT) mice, bone mass is lower in leptin-deficient ob/ob mice; osteopenia in growing ob/ob mice is due to decreased bone accrual, and is associated with reduced longitudinal bone growth, impaired cancellous bone maturation and increased marrow adipose tissue (MAT). However, leptin deficiency also results in gonadal dysfunction, disrupting production of gonadal hormones which regulate bone growth and turnover...

All domains of life have ATP-dependent compartmentalized proteases that sequester their peptidase sites on their interior. ATPase complexes will often associate with these compartmentalized proteases in order to unfold and inject substrates into the protease for degradation. Significant effort has been put into understanding how ATP hydrolysis is used to apply force to proteins and cause them to unfold. The unfolding kinetics of the bacterial ATPase, ClpX, have been shown to resemble a fast motor that traps unfolded intermediates as a strategy to unfold proteins...

BACKGROUND: Previous studies have shown that more than 20% of laboratories would have recommended inaccurate doses of Rh immune globulin (RhIG) in hypothetical cases. Efforts have been made in educating laboratories in correct dosing calculations; however, obstetricians are most often responsible for ordering RhIG. The objective of this study was to assess knowledge of RhIG indications and dosing among obstetrics and gynecology (OB/GYN) physicians in the United States. STUDY DESIGN AND METHODS: An anonymous 17- question online survey was distributed to all OB/GYN resident and attending physicians affiliated with US residency training programs...

BACKGROUND: Triple-Negative breast cancer (TNBC), accounts for a large percentage of breast cancer cases in India including Northeast India. TNBC has an unclear molecular aetiology and hence limited targeted therapies. Human breast is comprised of glandular, ductal, connective, and adipose tissues. Adipose tissue is composed of adipocytes. The adipocytes apart from being energy storage depots, are also active sources of adipocytokines and/or adipokines. The role of adipokines in breast cancer including TNBC has been sporadically documented...
