OBJECTIVES: Determining nutritional development in wild primates is difficult through observations because confirming dietary intake is challenging. Physiological measures are needed to determine the relative contributions of maternal milk and other foods at different ages, and time of weaning. We used fecal stable carbon and nitrogen isotopes (δ(13) C, δ(15) N) and fecal nitrogen concentrations (%N) from wild chimpanzees at Ngogo, Uganda, to derive physiological dietary indicators during the transition from total reliance on maternal milk to adult foods after weaning...

This paper provides a detailed look at how creationism originated in the United States and then explores how this evangelical trend was exported to Russia by American missionaries following the fall of the USSR. The comparison between these two countries is particularly interesting since the rivalry between the US and the USSR during the race to space caused both countries to revamp their science education. Yet, while political interests led both governments to focus on science education, creationist activities were simultaneously focused on diminishing the coverage of evolution in science classrooms...

Odonata (dragonflies and damselflies) present an unparalleled insect model to integrate evolutionary genomics with ecology for the study of insect evolution. Key features of Odonata include their ancient phylogenetic position, extensive phenotypic and ecological diversity, several unique evolutionary innovations, ease of study in the wild and usefulness as bioindicators for freshwater ecosystems worldwide. In this review, we synthesize studies on the evolution, ecology and physiology of odonates, highlighting those areas where the integration of ecology with genomics would yield significant insights into the evolutionary processes that would not be gained easily by working on other animal groups...

BACKGROUND AND OBJECTIVE: Magnetic resonance-guided laser-induced thermotherapy (MR-LITT) is a minimally invasive technique that shows promise in neuro-oncology due to its superiority in delivering precise minimally invasive thermal energy with minimal collateral damage. In this analysis we investigate initial data on MR-LITT's effect on dural based lesions. METHODS: Five patients were identified with dural based lesions (4 meningiomas, 1 solitary fibrous tumor) with clear evidence of radiological progression...

BACKGROUND: Whether high cardiovascular fitness is associated with reduced risk of venous thromboembolism (VTE) is unknown. The present study aims to determine whether high cardiovascular fitness reduces the risk of VTE. METHODS: A Swedish cohort of male conscripts (n = 773925) born in 1954-1970 with no history of previous VTE were followed from enlistment (1972-1990) until 2010. Data on cardiovascular fitness using a cycle ergonometric test (maximal aerobic workload in Watt [Wmax]) at conscription were linked with national hospital register data and the Multi-Generation Register...

We reported that supplementation with green tea extract (GTE) lowered the glycemic response to an oral glucose load following exercise but via an unknown mechanism. Here we examined the effect of supplementation with GTE on plasma glucose kinetics upon ingestion of a glucose beverage during exercise recovery. Eleven healthy, sedentary men (21±2 y; BMI=23±4 kg•m(-2), VO2peak=38±7 ml•kg(-1)•min(-1); mean±SD) ingested GTE (350 mg) or placebo (PLA) thrice daily for 7-d in a double-blind, crossover design...

There is growing demand for robust evidence to address complex social phenomena such as violence against women and girls (VAWG). Research partnerships between scientists and non-governmental or international organizations (NGO/IO) are increasingly popular, but can pose challenges, including concerns about potential conflicts of interest. Drawing on our experience collaborating on VAWG research, we describe challenges and contributions that NGO/IO and academic partners can make at different stages of the research process and the effects that collaborations can have on scientific inquiry...

BACKGROUND: There is increasing interest in measuring the quality of survivorship for patients admitted to the intensive care (ICU) for acute respiratory failure (ARF). However, there is substantial variability in the patient outcomes reported in studies evaluating these patients, with few data on which outcomes are essential to inform clinical practice. PURPOSE: To determine clinicians' perspectives on the outcome domains that should always be reported in studies evaluating ARF survivors after hospital discharge, and to compare findings between the US and Australian perspectives...

This study examined the effect of time pressure on face-matching accuracy. Across two experiments, observers decided whether pairs of faces depict one person or different people. Time pressure was exerted via two additional displays, which were constantly updated to inform observers on whether they were on track to meet or miss a time target. In this paradigm, faces were matched under increasing or decreasing (Experiment 1) and constant time pressure (Experiment 2), which varied from 10 to 2 seconds. In both experiments, time pressure reduced accuracy, but the point at which this declined varied from 8 to 2 seconds...

BACKGROUND: Detection of Ureaplasma, Mycoplasma and Candida spp. in the vagina during pregnancy has previously been associated with preterm birth (PTB). However, the prevalence of these microorganisms and the associated obstetric risks (likely to be population-specific) have not been determined in Australian women; furthermore, in the case of Ureaplasma spp., very few studies have attempted characterisation at the species level and none have examined genotype/serovar status to further refine risk assessment...

: Recently, in the prognostic assessment of ACS patients attention has been paid to hyperglycemia, leukocytosis, decreased GFR, anemia and thrombocytopenia as they are believed to worsen the prognosis. AIM: The aim of this study was to evaluate the results of basic laboratory blood tests in predicting the failure of in-hospital cardiac rehabilitation in post-STEMI patients - using an index of own design. MATERIALS AND METHODS: The study comprised 100 post-STEMI patients, 70 men and 30 women, aged 60,1±10,3 years, admitted for cardiac rehabilitation (phase II) to the Department of Internal Medicine and Cardiac Rehabilitation, WAM University Hospital in Lodz...

PURPOSE OF REVIEW: Dysregulated lipoprotein metabolism leads to increased plasma concentrations of atherogenic lipoproteins. We highlight the findings from recent studies of the effect of lipid-regulating therapies on apolipoprotein metabolism in humans employing endogenous labelling with stable isotopically labelled isotopomers. RECENT FINDINGS: Fish oil supplementation and niacin treatment both reduce fasting and postprandial triglyceride levels by decreasing the hepatic secretion of VLDL-apoB-100 (apoB) and apoB-48-containing chylomicron particles in obese and/or type 2 diabetes...

Clinical practice and the technology of cell processing for autologous stem cell transplantation has continued to evolve over the last two decades and merits review of current quality control expectations. The external regulatory era has improved quality and safety standards but there is still variable practice, with specific risks illuminated by a number of clinical incidents. Viable CD34(+) cell assays may fail to indicate significant losses in progenitor function during storage, particularly after cryopreservation, and there is a need to develop an alternative, real time functional assay to replace colony assays...

Cardiac MRI is frequently used in the diagnosis of cardiac amyloidosis. Feature tracking is a novel method of analyzing myocardial strain at the myocardial borders. We investigated myocardial deformation mechanics of both the right and left ventricles in patients with multiple myeloma with suspected cardiac amyloidosis. Comprehensive strain analysis was performed in 43 patients with multiple myeloma and suspected cardiac amyloidosis. MRI strain by feature tracking was measured using 2D cardiac performance analysis MR software (Tomtec, Germany)...

In recent years, many variants of percolation have been used to study network structure and the behavior of processes spreading on networks. These include bond percolation, site percolation, k-core percolation, bootstrap percolation, the generalized epidemic process, and the Watts threshold model (WTM). We show that-except for bond percolation-each of these processes arises as a special case of the WTM, and bond percolation arises from a small modification. In fact "heterogeneous k-core percolation," a corresponding "heterogeneous bootstrap percolation" model, and the generalized epidemic process are completely equivalent to one another and the WTM...

There are sex associated differences in the risk for cardiovascular comorbidities in obesity and metabolic syndrome. A common clinical finding in these diseases is the expansion of perivascular adipose tissues (PVAT) which is associated with alterations in their role as regulators of vessel function. PVAT hyperplasia and hypertrophy are dependent on the biology of populations of adipocyte progenitor cells (APC). It is currently unclear if PVAT enlargement diverges between males and females and the mechanisms linking APC biology with sexual dimorphism remain poorly understood...
