The impact of insecticide-treated cloth targets on the survival of Stegomyia polynesiensis (= Aedes polynesiensis) under laboratory and semi-field conditions in French Polynesia.

The impact of deltamethrin-impregnated cloth targets on Stegomyia polynesiensis (= Aedes polynesiensis) (Marks) (Diptera: Culicidae) was assessed under laboratory and semi-field settings in French Polynesia. Stegomyia polynesiensis females were released into small laboratory cages and large field cages containing either a deltamethrin-treated or an untreated navy blue cloth, and mosquito knock-down and mortality were assessed. The 24-h mortality rate in mosquitoes exposed to the insecticide-treated target in small cages was 98.

Food Handling Behaviors Observed in Consumers When Cooking Poultry and Eggs.

Previous research has shown that many consumers do not follow recommended food safety practices for cooking poultry and eggs, which can lead to exposure to Salmonella and Campylobacter. Past research has been done primarily through surveys and interviews, rather than observations. The objective of this project was to determine through observations whether consumers follow food safety guidelines.

Motivations for choosing various food groups based on individual foods.

Understanding "why people eat what they eat" is important for improving the lives of people around the world by helping provide industrial and social solutions for people to have greater pleasure and health from the foods they choose. The objective of this study was to investigate the motivations behind everyday choices of different food groups using a bottom-up approach that targeted the specific choices of foods and beverages people consumed at various times of a day. This study was conducted using an online survey included questions related to demographics, the most recent meal including specific food choices, and a slightly modified Eating Motivation Surveys (2 motivations were added, and Check-All-That-Apply procedure was used), which contained 50 sub-scales to measure 17 motivations including such topics as Liking, Pleasure, Convenience, Health, Price, Variety Seeking etc.

Mycoprotein reduces energy intake and postprandial insulin release without altering glucagon-like peptide-1 and peptide tyrosine-tyrosine concentrations in healthy overweight and obese adults: a randomised-controlled trial.

Dietary mycoprotein decreases energy intake in lean individuals. The effects in overweight individuals are unclear, and the mechanisms remain to be elucidated. This study aimed to investigate the effect of mycoprotein on energy intake, appetite regulation, and the metabolic phenotype in overweight and obese volunteers.

Increased colonic propionate reduces anticipatory reward responses in the human striatum to high-energy foods.

Background: Short-chain fatty acids (SCFAs), metabolites produced through the microbial fermentation of nondigestible dietary components, have key roles in energy homeostasis. Animal research suggests that colon-derived SCFAs modulate feeding behavior via central mechanisms. In humans, increased colonic production of the SCFA propionate acutely reduces energy intake.

Low-Income Housing Rental Assistance, Perceptions of Neighborhood Food Environment, and Dietary Patterns among Latino Adults: the AHOME Study.

Introduction: Federal rental assistance programs, in the form of the traditional public housing program and the Housing Choice Voucher Program (HCVP-formerly known as Section 8), are designed to reduce the economic rental burden for low-income residents. While residents using federal housing vouchers, which allow low-income residents in public housing to move out of public housing to rent-subsidized homes, have been found to be have better cardiovascular outcomes compared to the cardiovascular outcomes of low-income public housing residents, the mechanisms explaining these associations remains an understudied area.

Purpose: The aim of this study is to assess whether residents participating in HCVP or unassisted residents had greater access to healthy foods such as fruits and vegetables, and less access to unhealthy foods such as fast food and sugar sweetened beverages, when compared to residents living in public housing (referent group).

Lipolytic Markers, Insulin and Resting Fat Oxidation are Associated with Maximal Fat Oxidation.

The maximal capacity to oxidize fat during exercise (MFO) is associated with 24-h fat balance and insulin sensitivity. Understanding factors that influence MFO could have implications for metabolic health. We investigated relationships between selected plasma metabolites, hormones and overnight-fasted resting fat oxidation rates (Resting), with MFO.

Assessing DNA Barcodes for Species Identification in North American Reptiles and Amphibians in Natural History Collections.

Background: High rates of species discovery and loss have led to the urgent need for more rapid assessment of species diversity in the herpetofauna. DNA barcoding allows for the preliminary identification of species based on sequence divergence. Prior DNA barcoding work on reptiles and amphibians has revealed higher biodiversity counts than previously estimated due to cases of cryptic and undiscovered species.

Food safety behaviors observed in celebrity chefs across a variety of programs.

Background: Consumers obtain information about foodborne illness prevention from many sources, including television media. The purpose of this study was to evaluate a variety of cooking shows with celebrity chefs to understand their modeling of food safety behaviors.

Methods: Cooking shows (100 episodes) were watched from 24 celebrity chefs preparing meat dishes.

Tolerance Testing for Cooked Porridge made from a Sorghum Based Fortified Blended Food.

Products that will be prepared by consumers must be tolerant to various cooking procedures that those consumers may use. Fortified blended foods (FBFs) are used as a source of nutrition for disaster or famine relief in developing countries. Many FBFs are served as porridge and may have a wide of solids content, cooking times and variations in added ingredients.

Consumer Poultry Handling Behavior in the Grocery Store and In-Home Storage.

Considerable work on consumers' food safety habits has highlighted issues associated with home food preparation. However, consumer handling of foods, such as poultry, during shopping and storage has not been noted. The objective of this study was to determine consumer behaviors during purchasing and initial storage of raw poultry to determine potential cross-contamination issues.

An Analytical Pipeline for Quantitative Characterization of Dietary Intake: Application To Assess Grape Intake.

Lack of accurate dietary assessment in free-living populations requires discovery of new biomarkers reflecting food intake qualitatively and quantitatively to objectively evaluate effects of diet on health. We provide a proof-of-principle for an analytical pipeline to identify quantitative dietary biomarkers. Tartaric acid was identified by nuclear magnetic resonance spectroscopy as a dose-responsive urinary biomarker of grape intake and subsequently quantified in volunteers following a series of 4-day dietary interventions incorporating 0 g/day, 50 g/day, 100 g/day, and 150 g/day of grapes in standardized diets from a randomized controlled clinical trial.

Anti-PD-1 Inhibitor-Related Pneumonitis in Non-Small Cell Lung Cancer.

The recent approval of two PD-1 inhibitors for the treatment of non-small cell lung cancer (NSCLC) has rapidly led to the widespread use of these agents in oncology practices. Pneumonitis has been recognized as a potentially life-threatening adverse event among NSCLC patients treated with PD-1 inhibitors; however, the detailed clinical and radiographic manifestations of this entity remain to be described. We report on two cases of anti-PD-1 pneumonitis in advanced NSCLC patients treated with nivolumab after its FDA approval.

Accelerometer-measured sedentary time among Hispanic adults: Results from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL).

Excessive sedentary behavior is associated with negative health outcomes independent of physical activity. Objective estimates of time spent in sedentary behaviors are lacking among adults from diverse Hispanic/Latino backgrounds. The objective of this study was to describe accelerometer-assessed sedentary time in a large, representative sample of Hispanic/Latino adults living in the United States, and compare sedentary estimates by Hispanic/Latino background, sociodemographic characteristics and weight categories.

The Clinical Impact of Non-HLA Antibodies in Solid Organ Transplantation.

Antibody-mediated rejection in solid organ transplantation is associated with significant organ dysfunction and allograft loss. Donor-specific antibodies against human leukocyte antigens (HLAs) have been a major focus for research, clinical testing, and therapies. Recently, non-HLA autoantibodies to various endothelial antigens including angiotensin II type 1 receptor, endothelin-1 type A receptor, Major Histocompatibility Complex Class 1-Related Chain A, perlecan, and collagen V are emerging as both potential mediators of allograft dysfunction and targets for intervention.

Increasing Referrals to a YMCA-Based Diabetes Prevention Program: Effects of Electronic Referral System Modification and Provider Education in Federally Qualified Health Centers.

Introduction: The Diabetes Prevention Program has been translated to community settings with varying success. Although primary care referrals are used for identifying and enrolling eligible patients in the Diabetes Prevention Program, little is known about the effects of strategies to facilitate and sustain eligible patient referrals using electronic health record systems.

Methods: To facilitate and sustain patient referrals, a modification to the electronic health record system was made and combined with provider education in 6 federally qualified health centers in the Bronx, New York.

Cigarette Smoke Disrupted Lung Endothelial Barrier Integrity and Increased Susceptibility to Acute Lung Injury via Histone Deacetylase 6.

Epidemiologic evidence indicates that cigarette smoke (CS) is associated with the development of acute lung injury (ALI). We have previously shown that brief CS exposure exacerbates lipopolysaccharide (LPS)-induced ALI in vivo and endothelial barrier dysfunction in vitro. In this study, we found that CS also exacerbated Pseudomonas-induced ALI in mice.

Glucagon increases energy expenditure independently of brown adipose tissue activation in humans.

Aims: To investigate, for a given energy expenditure (EE) rise, the differential effects of glucagon infusion and cold exposure on brown adipose tissue (BAT) activation in humans.

Methods: Indirect calorimetry and supraclavicular thermography was performed in 11 healthy male volunteers before and after: cold exposure; glucagon infusion (at 23 °C); and vehicle infusion (at 23 °C). All volunteers underwent (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET)/CT scanning with cold exposure.

1α,25-dihydroxyvitamin D3 acts via transforming growth factor-β to up-regulate expression of immunosuppressive CD73 on human CD4+ Foxp3- T cells.

Vitamin D deficiency is associated with increased incidence and severity of various immune-mediated diseases. Active vitamin D (1α,25-dihydroxyvitamin D3; 1,25(OH)2 D3) up-regulates CD4(+) T-cell expression of the purine ectonucleotidase CD39, a molecule that is associated with the generation of anti-inflammatory adenosine. Here we aimed to investigate the direct impact of 1,25(OH)2 D3 on expression of the downstream ecto-5'-nucleotidase CD73 by human CD4 T cells, and components of the transforming growth factor-β (TGF-β) pathway, which have been implicated in the modulation of CD73 by murine T cells.

Mastermind-Like 1 Is Ubiquitinated: Functional Consequences for Notch Signaling.

Early studies demonstrated the involvement of ubiquitination of the Notch intracellular domain for rapid turnover of the transcriptional complex at Notch target genes. It was shown that this ubiquitination was promoted by the co-activator Mastermind like 1 (MAML1). MAML1 also contains numerous lysine residues that may also be ubiquitinated and necessary for protein regulation.

Round robin test on quantification of amyloid-β 1-42 in cerebrospinal fluid by mass spectrometry.

Introduction: Cerebrospinal fluid (CSF) amyloid-β 1-42 (Aβ42) is an important biomarker for Alzheimer's disease, both in diagnostics and to monitor disease-modifying therapies. However, there is a great need for standardization of methods used for quantification. To overcome problems associated with immunoassays, liquid chromatography-tandem mass spectrometry (LC-MS/MS) has emerged as a critical orthogonal alternative.

The self-management of longer-term depression: learning from the patient, a qualitative study.

Background: Depression is a common mental health condition now viewed as chronic or long-term. More than 50 % of people will have at least one further episode of depression after their first, and therefore it requires long-term management. However, little is known about the effectiveness of self-management in depression, in particular from the patients' perspective.

Depressive Symptomology and Hostile Affect among Latinos Using Housing Rental Assistance: the AHOME Study.

Studies show that those residing in households subsidized with federal housing vouchers exhibit fewer mental health problems than residents of public housing. The role of housing conditions and neighborhood quality in this relationship is unclear. This study investigated the relationship between rental assistance, housing and neighborhood conditions, and the risk of depressive symptomology and hostile affect among low-income Latino adults living in the Bronx, NY.
