Elucidating issues stressful for patients in predialysis and dialysis: from symptom to context.
Biopsychosocial problems experienced by renal disease patients were studied within a contextual framework the patients themselves defined, the findings being related to sociodemographic and medical data. Participants were 72 predialysis patients and 73 patients being treated by haemodialysis or peritoneal dialysis (106 men and 39 women, aged 18-84 years). Both stress-related global and situational
ICESat/GLAS Canopy Height Sensitivity Inferred from Airborne Lidar
Variations in laser properties and data acquisition times introduced inconsistencies in Geoscience Laser Altimeter System (GLAS) data. The effect of data inconsistencies, on two GLAS height retrieval methods, from three study sites, are investigated and validated against airborne laser scanning (ALS) percentile heights, from three data sources: all/first return point clouds, and raster canopy heig
Genetic data from nearly 63,000 women of European descent predicts DNA methylation biomarkers and epithelial ovarian cancer risk
Hematopoietic Reprogramming In Vitro Informs In Vivo Identification of Hemogenic Precursors to Definitive Hematopoietic Stem Cells
Definitive hematopoiesis emerges via an endothelial-to-hematopoietic transition in the embryo and placenta; however, the precursor cells to hemogenic endothelium are not defined phenotypically. We previously demonstrated that the induction of hematopoietic progenitors from fibroblasts progresses through hemogenic precursors that are Prom1+Sca1+CD34+CD45- (PS34CD45-). Guided by these studies, we an
Regulation of embryonic and induced pluripotency by aurora kinase-p53 signaling
Many signals must be integrated to maintain self-renewal and pluripotency in embryonic stem cells (ESCs) and to enable induced pluripotent stem cell (iPSC) reprogramming. However, the exact molecular regulatory mechanisms remain elusive. To unravel the essential internal and external signals required for sustaining the ESC state, we conducted a short hairpin (sh) RNA screen of 104 ESC-associated p
Myocardial performance index in female athletes
Background: Long-term intensive training leads to morphological and mechanical changes in the heart generally known as "athlete's heart". Previous studies have suggested that the diastolic and systolic function of the ventricles is unaltered in athletes compared to sedentary. The purpose of this study was to investigate myocardial performance index (MPI) by pulsed wave Doppler (PWD) and by tissue
Ischemic Preconditioning Confers Epigenetic Repression of Mtor and Induction of Autophagy Through G9a-Dependent H3K9 Dimethylation
BACKGROUND: Ischemic preconditioning (IPC) protects the heart from prolonged ischemic insult and reperfusion injury through a poorly understood mechanism. Post-translational modifications of histone residues can confer rapid and drastic switches in gene expression in response to various stimuli, including ischemia. The aim of this study was to investigate the effect of histone methylation in the r
Effect of Isomerization on Excited-State Dynamics of Carotenoid Fucoxanthin
Ultrafast transient absorption spectroscopy and single-wavelength anisotropy measurements were used to study the effect of isomerization on the excited-state properties of fucoxanthin in polar and nonpolar solvents. The excitation wavelengths were 477 nm for all-trans-fucoxanthin, and 333 and 477 nm for cis-fucoxanthin. All transient absorption spectra of the fucoxanthin isomers in polar solvents
Towards a political economy of degrowth
Since the 1970s, the degrowth idea has been proposed by scholars, public intellectuals and activists as a powerful call to reject the obsession of neoliberal capitalism with economic growth, an obsession which continues apace despite the global ecological crisis and rising inequalities. In the past decade, degrowth has gained momentum and become an umbrella term for various social movements which
The Metagenomics and Metadesign of the Subways and Urban Biomes (MetaSUB) International Consortium inaugural meeting report
The Metagenomics and Metadesign of the Subways and Urban Biomes (MetaSUB) International Consortium is a novel, interdisciplinary initiative comprised of experts across many fields, including genomics, data analysis, engineering, public health, and architecture. The ultimate goal of the MetaSUB Consortium is to improve city utilization and planning through the detection, measurement, and design of
Duplication assessments in Brassica vegetable accessions
There is extensive duplication of accessions among collection holders globally. To save costs, unwanted duplication should be avoided. This issue has been addressed internationally. In Europe, there are currently 35 Brassica collections located in 24 countries. Duplication may be identified not only by surveying passport data and seed transactions, but also by applying morphological or genetic cha
Genetic variants in CETP increase risk of intracerebral hemorrhage
OBJECTIVE: In observational epidemiologic studies, higher plasma high-density lipoprotein cholesterol (HDL-C) has been associated with increased risk of intracerebral hemorrhage (ICH). DNA sequence variants that decrease cholesteryl ester transfer protein (CETP) gene activity increase plasma HDL-C; as such, medicines that inhibit CETP and raise HDL-C are in clinical development. Here, we test the
Prognostic biomarkers in upper gastrointestinal adenocarcinoma
Estimates indicate that the global cancer burden may be ever-increasing. Gastric cancer is one of the major cancer forms. Despite its declining incidence, the high mortality of gastric cancer makes it the third most common cause of cancer-related death. Esophageal cancer is less common, but the incidence is increasing in parts of the world. Although some progress has been made in the treatment of
Autocatalytic amplification of Alzheimer-associated Aβ42 peptide aggregation in human cerebrospinal fluid
Alzheimer’s disease is linked to amyloid β (Aβ) peptide aggregation in the brain, and a detailed understanding of the molecular mechanism of Aβ aggregation may lead to improved diagnostics and therapeutics. While previous studies have been performed in pure buffer, we approach the mechanism in vivo using cerebrospinal fluid (CSF). We investigated the aggregation mechanism of Aβ42 in human CSF thro
An emerging governmentality of climate change loss and damage
Loss and damage is the “third pillar” of international climate governance alongside mitigation and adaptation. When mitigation and adaptation fail, losses and damages occur. Scholars have been reacting to international political discourse centred around governing actual or potential severe losses and damages from climate change. Large gaps exist in relation to understanding the underlying power di
Two subphenotypes of septic acute kidney injury are associated with different 90-day mortality and renal recovery
Background: The pathophysiology of septic acute kidney injury is inadequately understood. Recently, subphenotypes for sepsis and AKI have been derived. The objective of this study was to assess whether a combination of comorbidities, baseline clinical data, and biomarkers could classify meaningful subphenotypes in septic AKI with different outcomes. Methods: We performed a post hoc analysis of the
Assessing the potential and hydrological usefulness of the CHIRPS precipitation dataset over a complex topography in Pakistan
COVID-19 and All the Things That Kill Us : Research Ethics in the Time of Pandemic
How can we ethically research “the social” in times of social distancing? This paper considers the effects of a global pandemic on anthropological practice and scholarship. We suggest that, while much can be learned about the human experience during times of strife, we must first reflect on whether our research is beneficial, collaborative, or necessary. These considerations must constitute an ong
Women’s experiences of pregnancy after gastric bypass surgery
ABSTRACTINTRODUCTION Globally, 20% of women who become pregnant are obese at the time of conception. The prevalence of women becoming pregnant after gastric bypass (GBP) surgery has been increasing. Little is known regarding women’s experiences of pregnancy after GBP surgery and midwives can expect to care for an increasing number of women with prior GBP surgery. Midwives play an important role in
