Biased Inference of Selection Due to GC-Biased Gene Conversion and the Rate of Protein Evolution in Flycatchers When Accounting for It

The rate of recombination impacts on rates of protein evolution for at least two reasons: it affects the efficacy of selection due to linkage and influences sequence evolution through the process of GC-biased gene conversion (gBGC). We studied how recombination, via gBGC, affects inferences of selection in gene sequences using comparative genomic and population genomic data from the collared flyca

Targets for deprescribing in patients with hypertension and reflex syncope

BACKGROUND: We aimed to identify the target of deprescribing, i.e. the 24-hour SBP increase needed to achieve the greatest reduction of SBP drops.METHOD: Forty hypertensive patients (mean age 73.6 ± 9.3 years, 26 females) with reflex syncope and SBP drops on a screening ABPM were advised to withdraw or to reduce their therapy. The study objective was the reduction of SBP drops <90 mmHg and <100 mm

OxyHbMeter-a novel bedside medical device for monitoring cell-free hemoglobin in the cerebrospinal fluid-proof of principle

Delayed cerebral ischemia (DCI) occurs in up to one third of patients suffering from aneurysmal subarachnoid hemorrhage (aSAH). Untreated, it leads to secondary cerebral infarctions and is frequently associated with death or severe disability. After aneurysm rupture, erythrocytes in the subarachnoid space lyse and liberate free hemoglobin (Hb), a key driver for the development of DCI. Hemoglobin i

Big data, machine learning and uncertainty in foresight studies

Purpose: Currently, foresight studies have been adapted to incorporate new techniques based on big data and machine learning (BDML), which has led to new approaches and conceptual changes regarding uncertainty and how to prospect future. The purpose of this study is to explore the effects of BDML on foresight practice and on conceptual changes in uncertainty.Design/methodology/approach: The method

Genome-wide association and Mendelian randomization analysis provide insights into the shared genetic architecture between high-dimensional electrocardiographic features and ischemic heart disease

Observational studies have revealed that ischemic heart disease (IHD) has a unique manifestation on electrocardiographic (ECG). However, the genetic relationships between IHD and ECG remain unclear. We took 12-lead ECG as phenotypes to conduct genome-wide association studies (GWAS) for 41,960 samples from UK-Biobank (UKB). By leveraging large-scale GWAS summary of ECG and IHD (downloaded from Finn

Acral Melanoma Incidence and Survival Trends in 1990–2020: A Nationwide, Population-based Study

Acral melanoma is a clinical subtype of melanoma with high mortality, on which research is limited in scope. This study aimed to assess incidence trends and melanoma-specific survival rates for acral melanoma in the Swedish population from 1990 to 2020.This cross-sectional study included patients with an acral melanoma diagnosis from 1990 to 2020 from the nationwide, population-based Swedish Melan

Migrants as sustainability actors : Contrasting nation, city and migrant discourses and actions

Although it is widely recognized that migration is socially transformative, the potential contributions of migrants to transformations towards sustainability in their destination areas are often overlooked in mainstream discourse on environmentalism and sustainability. Here we seek to identify current narratives of migrants and sustainability across individual, urban, and national scales. Migrants

Trends and changes in the clinical use of lamotrigine

Purpose: To investigate long-term trends and changes in the pattern of use of lamotrigine (LTG). Methods: Retrospective survey of a large, routine therapeutic drug monitoring database. Results: Twelve thousand one hundred and seven samples from 4123 subjects were analysed from October 1999 to May 2007. Within this period, the mean daily dose rose from 183 to 253 mg, whereas the median dose remaine

Weyl semimetallic phase in high pressure CrSb2 and structural compression studies of its high pressure polymorphs

In this study, high pressure synchrotron powder X-ray diffraction is used to investigate the compression of two high pressure polymorphs of CrSb2. The first is the CuAl2-type polymorph with an eight-fold coordinated Cr, which can be quenched to ambient conditions from high-pressure high-temperature conditions. The second is the recently discovered MoP2-type polymorph, which is induced by compressi

Association between Maternal Dietary Diversity and Low Birth Weight in Central India: A Case-Control Study

Low birth weight (LBW) is one of the major public health challenges in India. LBW etiology is multifactorial and linked to multiple determinants, including maternal undernutrition and sociodemographic characteristics. The objective of the present endeavor was to assess how maternal dietary diversity and other sociodemographic factors among marginalized populations are associated with the incidence

Absorbed dose rate coefficients for 134Cs and 137Cs with steady-state distribution in the human body : S-coefficients revisited

In the event of an accidental release of radioactive elements from a nuclear power plant, it has been shown that the radionuclides contributing the most to long-term exposure are 134Cs and 137Cs. In the case of nuclear power plant fallout, with subsequent intake of radionuclides through the food chain, the internal absorbed dose to target tissues from protracted intake of radionuclides needs to be

Maintenance of basic endotracheal intubation skills with direct or video-assisted laryngoscopy : A randomized crossover follow-up study in inexperienced operators

Background: Laryngoscopy is a difficult skill to acquire and maintain and even more so by less frequent users. Numerous studies have compared limitations of direct laryngoscopic (DL) and video-assisted laryngoscopic (VL) techniques for endotracheal intubation in different scenarios, but individual retention over time of intubation skills with either technique has, to our knowledge, never been repo

Impact of glucocorticoids on the incidence of lupus-related major organ damage : A systematic literature review and meta-regression analysis of longitudinal observational studies

Objective In systemic lupus erythematosus (SLE), disease activity and glucocorticoid (GC) exposure are known to contribute to irreversible organ damage. We aimed to examine the association between GC exposure and organ damage occurrence. Methods We conducted a literature search (PubMed (Medline), Embase and Cochrane January 1966-October 2021). We identified original longitudinal observational stud

Morbidity and Outcomes After Distal Pancreatectomy for Primary Retroperitoneal Sarcoma : An Analysis by the Trans-Atlantic Australasian Retroperitoneal Sarcoma Working Group

Background: Multi-visceral resection often is used in the treatment of retroperitoneal sarcoma (RPS). The morbidity after distal pancreatectomy for primary pancreatic cancer is well-documented, but the outcomes after distal pancreatectomy for primary RPS are not. This study aimed to evaluate morbidity and oncologic outcomes after distal pancreatectomy for primary RPS. Methods: In this study, 26 sa

An experimental investigation on the thermal augmentation of internal endwall in a two-pass duct using an array of delta-winglet vortex generator pair

The present study experimentally demonstrates a novel design for an internal endwall in a two-pass duct heat exchanger. An array of delta-winglet vortex generator pairs with different aspect ratio, angle of attack, configuration are mounted on the internal endwall in a U duct. Liquid crystal thermalgraphy and static pressure measurements are utilized in this study to evaluate the heat transfer, th

Short-lived species move uphill faster under climate change

Climate change is pushing species ranges and abundances towards the poles and mountain tops. Although many studies have documented local altitudinal shifts, knowledge of general patterns at a large spatial scale, such as a whole mountain range, is scarce. From a conservation perspective, studying altitudinal shifts in wildlife is relevant because mountain regions often represent biodiversity hotsp
