Common Missense Variant in the Glucokinase Regulatory Protein Gene Is Associated With Increased Plasma Triglyceride and C-Reactive Protein but Lower Fasting Glucose Concentrations

OBJECTIVE-Using the genome-wide association approach, we recently identified the glucokinase regulatory protein gene (GCKR, rs780094) region as a novel quantitative trait locus for plasma triglyceride concentration in Europeans. Here, we sought to study the association of GCKR variants with metabolic phenotypes, including measures of glucose homeostasis, to evaluate the GCYR locus in samples of no

Comparison of historical medical spending patterns among the BRICS and G7

OBJECTIVE: The past few decades have been marked by a bold increase in national health spending across the globe. Rather successful health reforms in leading emerging markets such as BRICS reveal a reshaping of their medical care-related expenditures. There is a scarcity of evidence explaining differences in long-term medical spending patterns between top ranked G7 traditional welfare economies an

A physiology-based Earth observation model indicates stagnation in the global gross primary production during recent decades

Earth observation-based estimates of global gross primary production (GPP) are essential for understanding the response of the terrestrial biosphere to climatic change and other anthropogenic forcing. In this study, we attempt an ecosystem-level physiological approach of estimating GPP using an asymptotic light response function (LRF) between GPP and incoming photosynthetically active radiation (P

A comprehensive quantification of global nitrous oxide sources and sinks

Nitrous oxide (N2O), like carbon dioxide, is a long-lived greenhouse gas that accumulates in the atmosphere. Over the past 150 years, increasing atmospheric N2O concentrations have contributed to stratospheric ozone depletion1 and climate change2, with the current rate of increase estimated at 2 per cent per decade. Existing national inventories do not provide a full picture of N2O emissions, owin

Genredigering - ett nytt sätt att diskriminera på?

Efter att det blev känt att en kinesisk forskare hade genredigerat två embryon, blev genredigering ett mycket omtalat ämne runt om i världen. Händelsen ledde till stora diskussioner på olika nivåer och ledde till många rekommendationer kring de etiska avgränsningar som bör göras. Vetenskapen går ständigt framåt och därför är det av betydelse att göra en omfattande analys av hur rättsläget inom g

Palynostratigraphy of the Cretaceous-Paleogene mass-extinction interval of the Southern Hemisphere

The palynofloral changes around the Cretaceous-Paleogene (K-Pg) mass extinction event reveal the fine details of vegetation response to a global environmental crisis-in this case an asteroid impact in Mexico 65.5 million years ago. Due to the extinction of several plant taxa at the K-Pg boundary, palynostratigraphy is a prime tool for localizing the Cretaceous-Paleogene boundary in non-marine succ

Endotoxin, ergosterol, fungal DNA and allergens in dust from schools in johor bahru, malaysia- associations with asthma and respiratory infections in pupils.

There are few studies on associations between respiratory health and allergens, fungal and bacterial compounds in schools in tropical countries. The aim was to study associations between respiratory symptoms in pupils and ethnicity, chemical microbial markers, allergens and fungal DNA in settled dust in schools in Malaysia. Totally 462 pupils (96%) from 8 randomly selected secondary schools in Joh

Adherence to the EAT-Lancet reference diet and risk of type 2 diabetes, metabolic dysfunction-associated steatotic liver disease, and their co-occurrence

Background and aims: The EAT-Lancet Commission proposed a healthy dietary pattern to prevent diet-related diseases while promoting planetary sustainability, but little is known regarding its associations with type 2 diabetes (T2D) and metabolic dysfunction-associated steatotic liver disease (MASLD), both of which are highly prevalent and frequently co-exist. We aimed to assess association of this

Effektivisering av snöröjning

Entrepreneurs have difficulties in performing maintenance activities due to the increasing intensity of train services and failing infrastructure. Annually, the state loses billions of SEK due to delays caused by failures in infrastructure or maintenance not performed on time. The largest amounts of delays occur during winter time, when our infrastructure cannot cope with the climate as it is expo

Environmental controls on marine ecosystem recovery following mass extinctions, with an example from the Early Triassic

The recovery of marine ecosystems following a mass extinction event involves an extended interval of increasing biotic diversity and ecosystem complexity. The pace of recovery may be controlled by intrinsic ecosystem or extrinsic environmental factors. Here, we present an analysis of changes in marine conditions following the end-Permian mass extinction with the objective of evaluating the role of

Expression and activity of critical digestive enzymes during early larval development of the veined rapa whelk, Rapana venosa (Valenciennes, 1846)

Metamorphosis is a vital developmental event in the life cycle of molluscs and involves extensive morphological and physiological changes. Remodeling of the digestive system is suggested to occur anticipatorily to enable the larva to shift its diet (from filter feeding on microalgae to feeding on small bivalves) after metamorphosis. Changes in the profiles and activities of digestive enzymes, the

Temperature adaptation of soil microbial respiration in alpine, boreal and tropical soils : An application of the square root (Ratkowsky) model

Warming is expected to stimulate soil microbial respiration triggering a positive soil carbon-climate feedback loop while a consensus remains elusive regarding the magnitude of this feedback. This is partly due to our limited understanding of the temperature-adaptive response of soil microbial respiration, especially over broad climatic scales. We used the square root (Ratkowsky) model to calculat

Maternal and perinatal outcomes with COVID-19 : A systematic review of 108 pregnancies

INTRODUCTION: The pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has exposed vulnerable populations to an unprecedented global health crisis. The knowledge gained from previous human coronavirus outbreaks suggests that pregnant women and their fetuses are particularly susceptible to poor outcomes. The objective of this study was to summarize the clinical manife

Environmental and physiological controls on diurnal and seasonal patterns of biogenic volatile organic compound emissions from five dominant woody species under field conditions

Biogenic volatile organic compounds (BVOCs) play essential roles in tropospheric chemistry, on both regional and global scales. The emissions of large quantities of species-specific BVOC depend not only on environmental (temperature, T; photosynthetically active radiation, PAR), but also physiological parameters (i.e. net photosynthetic rate, Pn; transpiration rate, Tr; stomatal conductance, gs an

The sensitivity of ginkgo leaf unfolding to the temperature and photoperiod decreases with increasing elevation

Climate change substantially affects plant phenology, resulting in earlier vegetation onset across temperate and boreal regions. Phenological shifts caused by warming may alter species interactions across trophic levels because of species-specific responses, and influence the reproductive success of dioecious species if the phenological sensitivity to warming (ST) differs between genders. We used

To shake or not to shake : 13 C-based evidence on anaerobic methane oxidation in paddy soil

The anaerobic oxidation of methane (AOM) removes most of the biologically produced methane (CH 4 ) from marine ecosystems before it enters the atmosphere and thus mitigates greenhouse gas emissions. As compared to marine environments, surprisingly little is known about the role of AOM in terrestrial ecosystems. Particularly, how AOM controls the CH 4 budget of paddy soils is unexplored, partly
