Experimental field studies with non-human primates
submitted by tormik97 28 minutes ago - Topic: Health
One way to study language evolution is to compare human communication with closely related non-human primate species. This comparative approach has turned to be especially productive if subjects are studied under natural field conditions in which they have evolved. Various observation techniques have been developed, but field experiments are often needed to clarify underlying cause–effect rel...



The neuroanatomic and neurophysiological infrastructure for speech and language
submitted by tormik97 29 minutes ago - Topic: Health
New tools and new ideas have changed how we think about the neurobiological foundations of speech and language processing. This perspective focuses on two areas of progress. First, focusing on spatial organization in the human brain, the revised functional anatomy for speech and language is discussed. The complexity of the network organization undermines the well-regarded classical model and su...

What optogenetic stimulation is telling us (and failing to tell us) about fast neurotransmitters and neuromodulators in brain circuits for wake–sleep regulation
submitted by tormik97 31 minutes ago - Topic: Health
In the last eight years optogenetic tools have been widely used to identify functional synaptic connectivity between specific neuronal populations. Most of our knowledge comes from the photo-activation of channelrhodopsin-2 (ChR2) expressing inputs that release glutamate and GABA. More recent studies have been reporting releases of acetylcholine and biogenic amines but direct evidence for photo...

Neuromodulation and aging: implications of aging neuronal gain control on cognition
submitted by tormik97 32 minutes ago - Topic: Health
The efficacy of various transmitter systems declines with advancing age. Of particular interest, various pre-synaptic and post-synaptic components of the dopaminergic system change across the human lifespan; impairments in these components play important roles in cognitive deficits commonly observed in the elderly. Here, we review evidence from recent multimodal neuroimaging, pharmacological an...

The molecular mechanism of intestinal levodopa absorption and its possible implications for the treatment of Parkinson's disease
submitted by pandhiiponkor 41 minutes ago - Topic: Health
Levodopa (L-DOPA) is the naturally occurring precursor amino acid for dopamine and the main therapeutic agent for neurologic disorders due to dopamine depletion, such as Parkinson's disease. Levodopa absorption in small intestine has been suggested to be mediated by the large neutral amino acids transport machinery, but the identity of the involved transporters is unknown. Clinically, co-admini...



Comparative study of thermal reaction norms for development in ants
submitted by toareno 48 minutes ago - Topic: Agriculture
This is the first compilation of our research and data from the literature on the duration and thermal reaction norms for development in ants. Altogether, 97 regression lines characterizing the linear dependence of ant brood (egg, larval, prepupal and pupal) development on temperature were obtained for 33 species from 15 genera and three subfamilies. Significant positive correlations between th...

Explaining Variations in Immigrants’ Satisfaction with Their Settlement Experience
submitted by bole 58 minutes ago - Topic: Health
The study seeks to determine the extent to which economic integration factors, social integration factors, human capital and area-level factors are associated with immigrants’ satisfaction with their settlement experience in Canada. The Longitudinal Survey of Immigrants to Canada (Wave 1) and the 2001 Census Profiles are used for multilevel modelling. The study confirmed that factors from all...


Strands of Diaspora: The Resettlement Experience of Jewish Immigrants to Australia
submitted by bole 59 minutes ago - Topic: Health
While in contemporary usage the term ‘diaspora’ is often construed to denote any deterritorialised or transnational population, it most meaningfully refers to dispersal and resettlement of a population elsewhere. Jews are a prime example of such a diaspora. While in the Australian context, Jewish immigrants have many of the middle class and disproportionately professional occupational backg...

On carrots and curiosity: Eating fruit and vegetables is associated with greater flourishing in daily life
submitted by crairsch 1 hour ago - Topic: Health
Our aim was to determine whether eating fruit and vegetables (FV) is associated with other markers of well-being beyond happiness and life satisfaction. Towards this aim, we tested whether FV consumption is associated with greater eudaemonic well-being – a state of flourishing characterized by feelings of engagement, meaning, and purpose in life. We also tested associations with two eudaemoni...

submitted by irecoggriy 1 hour ago - Topic: Health
To examine the effect of body mass index (BMI) on postoperative 30-day morbidity and mortality after surgery for endometrial cancer (EC). A retrospective cohort study. National Surgical Quality Improvement Program data. Patients with EC who underwent surgery from 2005-2011 were identified. Women were divided into: normal weight (BMI18-<30) (NW), obese (30-<40) (O), morbidly obese ...

The development of the commercial weather services market in Europe: 1970–2012
submitted by ogranamest 1 hour ago - Topic: Geography
This study explores the development of commercial weather services in Europe over the past 40 years. The market is traced from its very low levels in the 1970s to its present size of ∼ €300 million per annum (excluding aviation). Ways in which growth in the European weather market has been affected by government policies relating to the organization of weather services and the philosophical...
