Relationship between adolescent anemia and school attendance observed during a nationally representative survey in India

BACKGROUND: Anemia has been suggested to be related with schooling outcomes in India. Less is known, however, about whether the observed relationship persists after accounting for all household-level factors which may confound the association between anemia and schooling.METHODS: Nationally representative data on adolescents aged 15-18 years with data on measured hemoglobin level and school attend

Alcohol intake and endogenous sex hormones in women : Meta-analysis of cohort studies and Mendelian randomization

Background: The mechanisms underlying alcohol-induced breast carcinogenesis are not fully understood but may involve hormonal changes. Methods: Cross-sectional associations were investigated between self-reported alcohol intake and serum or plasma concentrations of estradiol, estrone, progesterone (in premenopausal women only), testosterone, androstenedione, dehydroepiandrosterone sulfate, and sex

Continuous mapping of forest canopy height using ICESat-2 data and a weighted kernel integration of multi-temporal multi-source remote sensing data aided by Google Earth Engine

Forest Canopy Height (FCH) is a crucial parameter that offers valuable insights into forest structure. Spaceborne LiDAR missions provide accurate FCH measurements, but a significant challenge is their point-based measurements lacking spatial continuity. This study integrated ICESat-2’s ATL08-derived FCH values with multi-temporal and multi-source remote sensing (RS) datasets to generate continuous

Woody biomass-based transportation fuels – A comparative techno-economic study

Production of synthetic vehicle fuels from biomass is a hot topic. There are several alternative fuels to consider when evaluating properties such as cost of production and energy efficiency to both product and final use in a road vehicle. Thermochemical conversion via gasification and downstream synthesis of fuels as well as biochemical conversion of woody biomass to ethanol is considered in this

Three-dimensional ultrasound assessment of the cervix for predicting time to spontaneous onset of labor and time to delivery in prolonged pregnancy

Objectives To determine whether three-dimensional (3D) ultrasound including power Doppler examination of the cervix is useful for predicting time to spontaneous onset of labor or time to delivery in prolonged pregnancy. Methods A prospective study was conducted in 60 women who went into spontaneous labor. All underwent transvaginal 3D power Doppler ultrasound examination of the cervix immediately

Supermacroporous cryogel matrix for integrated protein isolation - Immobilized metal affinity chromatographic purification of urokinase from cell culture broth of a human kidney cell line

A new type of supermacroporous, monolithic, cryogel affinity adsorbent was developed, allowing the specific capture of urokinase from conditioned media of human fibrosarcoma cell line HT1080. The affinity adsorbent was designed with the objective of using it as a capture column in an integrated perfusion/protein separation bioreactor setup. A comparative study between the utility of this novel cry

Upscaling of methane exchange in a boreal forest using soil chamber measurements and high-resolution LiDAR elevation data

Forest soils are generally considered to be net sinks of methane (CH4), but CH4 fluxes vary spatially depending on soil conditions. Measuring CH4 exchange with chambers, which are commonly used for this purpose, might not result in representative fluxes at site scale. Appropriate methods for upscaling CH4 fluxes from point measurements to site scale are therefore needed. At the boreal forest resea

Better Prognosis of Patients with Glioma Expressing FGF2-Dependent PDGFRA Irrespective of Morphological Diagnosis.

Signaling of platelet derived growth factor receptor alpha (PDGFRA) is critically involved in the development of gliomas. However, the clinical relevance of PDGFRA expression in glioma subtypes and the mechanisms of PDGFRA expression in gliomas have been controversial. Under the supervision of morphological diagnosis, analysis of the GSE16011 and the Repository of Molecular Brain Neoplasia Data (R

Immune function in a free-living bird varies over the annual cycle, but seasonal patterns differ between years

A central hypothesis of eco-immunology proposes trade-offs between immune defences and competing physiological and behavioural processes, leading to immunological variation within and among annual-cycle stages, as has been revealed for some species. However, few studies have simultaneously investigated patterns of multiple immune indices over the entire annual cycle in free-living birds, and none

Nocturia and Quality of Life: Results from the Boston Area Community Health Survey

Background: Nocturia, a common complaint in aging men and women, is frequently cited as the cause of nocturnal awakenings leading to sleep loss, daytime fatigue, and reduced quality of life (QOL). Objective: Investigate the association of nocturia with QOL and depressive symptoms among men and women. Design, setting, and participants: A population-based epidemiologic survey of urologic symptoms am

Health-related quality of life in patients with different stages of liver disease induced by hepatitis C

Objective. Patients with hepatitis C have been shown to have impaired health-related quality of life (HRQoL). The aim of this study was to determine HRQoL in patients in different stages of hepatitis C virus (HCV) and to compare HRQoL in HCV cirrhosis with non-HCV-induced cirrhosis. Material and methods. Out of 489 consecutive patients who fulfilled the inclusion criteria, 472 (96%) agreed to part

Minimally modified LDL upregulates endothelin type B receptors in rat coronary artery via ERK1/2 MAPK and NF-kappa B pathways

Minimally modified low density lipoprotein (mmLDL) is a well-known risk factor for coronary artery disease. Upregulation of vascular endothelin type B (ETB) receptors on the vascular smooth muscle cells is predicted to be the molecular mechanism that leads to cardiovascular pathogenesis. The objective of the present study was to examine the hypothesis that mmLDL upregulates ETB receptors in rat co

Correlation between disability and MRI findings in lumbar spinal stenosis A prospective study of 109 patients operated on by decompression

Background and purpose MRI is the modality of choice when diagnosing spinal stenosis but it also shows that stenosis is prevalent in asymptomatic subjects over 60. The relationship between preoperative health-related quality of life, functional status, leg and back pain, and the objectively measured dural sac area in single and multilevel stenosis is unknown. We assessed this relationship in a pro

A model-based methodology for the analysis and design of atomic layer deposition processes-Part I: Mechanistic modelling of continuous flow reactors

This paper presents the development of an experimentally validated model that mechanistically comprehends the complex interaction between the gas-phase fluid dynamics, the mass transport of individual species, and the heterogeneous gas-surface reaction mechanism in a continuous cross-flow atomic layer deposition (ALD) reactor. The developed ALD gas-surface reaction mechanism, purely based on conse

A feather hydrogen isoscape for Mexico

Developing useful biological isoscapes for areas of the world is a priority. This is the case for Mexico that hosts a large percentage of North America's Neotropical migrant birds. Here we investigated the use of House Sparrow (Passer domesticus) feathers to create a spatially explicit feather deuterium isoscape for that country using samples (n=461) that were collected across Mexico. Considerable

Plasma membrane cyclic nucleotide phosphodiesterase 3B (PDE3B) is associated with caveolae in primary adipocytes.

Caveolae, plasma membrane invaginations particularly abundant in adipocytes, have been suggested to be important in organizing insulin signalling. Insulin-induced activation of the membrane bound cAMP degrading enzyme, phosphodiesterase 3B (PDE3B) is a key step in insulin-mediated inhibition of lipolysis and is also involved in the regulation of insulin-mediated glucose uptake and lipogenesis in a

A sequential method to identify underlying causes from industrial accidents reported to the MARS database

This paper presents a method designed to identify underlying causes leading to industrial accidents. The method developed intends to facilitate the learning process from accidents by identifying possible causes related to the accidents that were not directly stated in an accident report, but that can be deduced following the description of the event, in particular with regard to the quality of the

Aspects of retransfusion of shed blood in cardiac surgery

Popular Abstract in Swedish De flesta större operationer på hjärtat idag kräver att hjärtat under en del av operationen står stilla utan att blod cirkulerar igenom det. För att kunna bibehålla ett blodflöde av syresatt blod genom kroppen kopplas en hjärt-lungmaskin till patienten. Blodet förs via slangar från höger förmak först ner till ett uppsamlingskärl, varifrån blodet pumpas vidare genom en oThe use of cardiotomy suction during open heart surgery with cardiopulmonary bypass (CPB) has a long tradition and often regarded as mandatory. Recently, studies have described potentially negative effects of cardiotomy suction with activation of the complement system, enhanced inflammatory response, hemolysis and coagulopathy. Emboli of various matters has also been studied. Whether they affect t

A Russian record of a Middle Ordovician meteorite shower: Extraterrestrial chromite at Lynna River, St. Petersburg region

Numerous fossil meteorites and high concentrations of sediment-dispersed extraterrestrial chromite (EC) grains with ordinary chondritic composition have previously been documented from 467 +/- 1.6 Ma Middle Ordovician (Darriwilian) strata. These finds probably reflect a temporarily enhanced influx of L-chondritic matter, following the disruption of the L-chondrite parent body in the asteroid belt
