The centriole/basal body is a eukaryotic organelle that plays essential roles in cell division and signaling. Among five known core centriole proteins, SPD-2/Cep192 is the first recruited to the site of daughter centriole formation and regulates the centriolar localization of the other components in C. elegans and in humans. However, the molecular basis for SPD-2 centriolar localization remains unknown. Here we describe a new centriole component, the coiled-coil protein SAS-7, as a regulator of centriole duplication, assembly and elongation...

Older adults are theorized to benefit from proactive forms of emotion regulation that allow them to avoid negative stimuli (Charles, 2010). To test this, we examined choices as a form of emotion regulation. In two studies investigating age differences, participants selected affective stimuli using a cable television interface, while choices and mood were recorded. In lab-based Study 1, older adults spent more time watching neutral channels, but younger adults spent more time watching positive ones. Older adults also watched more low-arousal content, while younger adults watched more high-arousal content...

Maintaining weight loss is a significant challenge in combating obesity. The goal of Maintaining Activity and Nutrition through Technology-Assisted Innovation in Primary Care (MAINTAIN-pc) is to evaluate the use of tools delivered through an electronic health record (EHR) and patient portal, with or without health coach support, to help primary care patients maintain weight loss. EHR tools include flowsheets, standardized surveys, and secure patient messaging. Inclusion criteria were age 18-75years, voluntary 5% weight loss in the past 2years with prior BMI≥25kg/m(2), and no bariatric procedures in past 5years...

INTRODUCTION: Increasing age has been correlated with shorter survival in ovarian cancer patients, a finding attributed to diminished tolerance of standard therapy. Elderly patients, however, are less likely to enroll on clinical trials; thus, limited data exists to evaluate their response to front line treatment. This study describes how elderly patients on trial fared, with respect to toxicity and response, compared to younger women. METHODS: A retrospective cohort study was performed of ovarian cancer patients enrolled in front line chemotherapy trials at our institution between 2000 and 2013...

A locally validated tool was needed to evaluate long-term dietary intake in rural Bangladesh. We assessed the validity of a 42-item dish-based semi-quantitative food frequency questionnaire (FFQ) using two 3-day food diaries (FDs). We selected a random subset of 47 families (190 participants) from a longitudinal arsenic biomonitoring study in Bangladesh to administer the FFQ. Two 3-day FDs were completed by the female head of the households and we used an adult male equivalent method to estimate the FD for the other participants...

We conducted a cluster-randomized trial to estimate effects of directly observed combination antiretroviral therapy (DOT-cART) on retention with viral suppression among HIV-positive adults in Peru. We randomly allocated facilities to receive the 12-month intervention plus the standard of care, including adherence support provided through accompaniment. In the intervention arm, health workers supervised doses, twice daily, and accompanied patients to appointments. Among 356 patients, intention-to-treat analyses showed no statistically significant benefit of DOT, relative to no-DOT, at 12 or 24 months (adjusted probability of primary outcome: 0...

RATIONALE: Conventional three-dimensional (3D) printing techniques cannot produce structures of the size at which individual cells interact. OBJECTIVE: Here, we used multiphoton-excited, 3-dimensional printing (MPE-3DP) to generate a native-like, extracellular matrix (ECM) scaffold with submicron resolution, and then seeded the scaffold with cardiomyocytes (CMs), smooth-muscle cells (SMCs), and endothelial cells (ECs) that had been differentiated from human induced-pluripotent stem cells (iPSCs) to generate a human, iPSC-derived cardiac muscle patch (hCMP), which was subsequently evaluated in a murine model of myocardial infarction (MI)...

The complexity of the human exposome-the totality of environmental exposures encountered from birth to death-motivates systematic, high-throughput approaches to discover the environmental determinants of disease. In this review, we describe the state of science in analyzing the human exposome and provide recommendations for the public health community to consider in dealing with analytic challenges of exposome-based biomedical research. We describe extant and novel analytic methods needed to associate the exposome with critical health outcomes and contextualize the data-centered challenges by drawing parallels to other research endeavors such as human genomics research...

In the past decade, extracellular vesicles (EVs) have emerged as a key cell-free strategy for the treatment of a range of pathologies, including cancer, myocardial infarction, and inflammatory diseases. Indeed, the field is rapidly transitioning from promising in vitro reports toward in vivo animal models and early clinical studies. These investigations exploit the high physicochemical stability and biocompatibility of EVs as well as their innate capacity to communicate with cells via signal transduction and membrane fusion...

Research linking reading literary fiction to empathy supports health humanities programs in which reflective writing accompanies close readings of texts, both to explore principles of storytelling (narrative arc and concrete language) and to promote an examination of biases in care. Little attention has been paid to the possible contribution of guided fiction-writing in health humanities curricula toward enhancing cultural competence among health professionals, both clinical and community-based. Through an analysis of the short story "Pie Dance" by Molly Giles, juxtaposed with descriptions of specific writing exercises, this paper explains how the demands of writing fiction promote cultural competency...

We report a new method to quantify the affinity of small molecules for proteins. This method is based on Förster resonance energy transfer (FRET) between endogenous tryptophan (Trp) residues and the coumarin-derived fluorophore Pacific Blue (PB). Tryptophan residues are frequently found in proteins near ligand-binding sites, making this approach potentially applicable to a wide range of systems. To improve access to PB, we developed a scalable multigram synthesis of this fluorophore, starting with inexpensive 2,3,4,5-tetrafluorobenzoic acid...

Tissue architecture is intimately linked with its functions, and loss of tissue organization is often associated with pathologies. The intricate depth-dependent extracellular matrix (ECM) arrangement in articular cartilage is critical to its biomechanical functions. In this study, we developed a Raman spectroscopic imaging approach to gain new insight into the depth-dependent arrangement of native and tissue-engineered articular cartilage using bovine tissues and cells. Our results revealed previously unreported tissue complexity into at least six zones above the tidemark based on a principal component analysis and k-means clustering analysis of the distribution and orientation of the main ECM components...

INTRODUCTION: Bio-Medical Waste (BMW) management is of utmost importance as its improper management poses serious threat to health care workers, waste handlers, patients, care givers, community and finally the environment. Simultaneously, the health care providers should know the quantity of waste generated in their facility and try to reduce the waste generation in day-to-day work because lesser amount of BMW means a lesser burden on waste disposal work and cost saving. AIM: To have an overview of management of BMW in a tertiary care teaching hospital so that effective interventions and implementations can be carried out for better outcome...
