Metataxonomic analysis of halophilic archaea community in two geothermal oases in the southern Tunisian Sahara

This study assesses halophilic archaea's phylogenetic diversity in southern Tunisia's geothermal water. In the arid southern regions, limited surface freshwater resources make geothermal waters a vital source for oases and greenhouse irrigation. Three samples, including water, sediment, and halite-soil crust, were collected downstream of two geothermal springs of the Ksar Ghilane (KGH) and Zaouet

Halogen-Bonded Hole-Transport Material Enhances Open-Circuit Voltage of Inverted Perovskite Solar Cells

Interfacial properties of a hole-transport material (HTM) and a perovskite layer are of high importance, which can influence the interfacial charge transfer dynamics as well as the growth of perovskite bulk crystals particularly in inverted structure. The halogen bonding (XB) has been recognized as a powerful functional group to be integrated with new small molecule HTMs. Herein, a carbazole-ba

The corky root rot pathogen Pyrenochaeta lycopersici secretes a proteinaceous inducer of cell death affecting host plants differentially

Pathogenic isolates of Pyrenochaeta lycopersici, the causal agent of corky root rot of tomato, secrete cell death in tomato 1 (CDiT1), a homodimeric protein of 35 kDa inducing cell death after infiltration into the leaf apoplast of tomato. CDiT1 was purified by fast protein liquid chromatography, characterized by mass spectrometry and cDNA cloning. Its activity was confirmed after infiltration of

Oral microbiota in patients with atherosclerosis

Background and aims: Recent evidence suggests that the microbiota may be considered as an environmental factor that contributes to the development of atherosclerosis. Periodontal disease has been associated with cardio- and cerebrovascular events, and inflammation in the periodontium is suggested to increase the systemic inflammatory level of the host, which may in turn influence plaque compositio

Critical role for a stage-specific actin in male exflagellation of the malaria parasite

Male gametogenesis occurs directly after uptake of malaria parasites by the mosquito vector and leads to the release of eight nucleated flagellar gametes. Here, we report that one of the two parasite actin isoforms, named actin II, is essential for this process. Disruption of actin II in Plasmodium berghei resulted in viable asexual blood stages, but male gametogenesis was specifically inhibited.

Comparative structural analysis of lipid binding START domains

BACKGROUND: Steroidogenic acute regulatory (StAR) protein related lipid transfer (START) domains are small globular modules that form a cavity where lipids and lipid hormones bind. These domains can transport ligands to facilitate lipid exchange between biological membranes, and they have been postulated to modulate the activity of other domains of the protein in response to ligand binding. More t

Inequality : Economic and Social Issues

Inequalities of opportunity affect a person’s life expectancy and access to basic services and human rights through discrimination, abuse, and lack of access to justice. High levels of inequality of opportunity discourage skill accumulation, choke economic and social mobility, and, consequently, depress economic growth. Inequality also entrenches uncertainty, vulnerability, and insecurity; undermi

Analyzing love

What is love? Is it an uncontrollable emotion? Is it, instead, socially shaped, both an emotion and a social practice? Can the bonds of care and affection between humans and non-human animals be said to be on a par with parent-child relationships between humans? Do parents owe love to their children – and do mothers and fathers, respectively, owe it to different degrees? Do subversive weddings cha

Development and External Validation of a Combined Clinical–Radiomic Model for Predicting Insufficient Hypertrophy of the Future Liver Remnant following Portal Vein Embolization

ObjectivesThis study aimed to develop and externally validate a model for predicting insufficient future liver remnant (FLR) hypertrophy after portal vein embolization (PVE) based on clinical factors and radiomics of pretreatment computed tomography (CT)Patients and methodsClinical information and CT scans of 241 consecutive patients from three Swedish centers were retrospectively collected. One c

Early-Scheduled Handover Preparation in 5G NR Millimeter-Wave Systems

The handover (HO) procedure is one of the most critical functions in a cellular network driven by measurements of the user channel of the serving and neighboring cells. The success rate of the entire HO procedure is significantly affected by the preparation stage. As massive Multiple-Input Multiple-Output (MIMO) systems with large antenna arrays allow resolving finer details of channel behavior, w

Exploring the influence of augmented reality on tourist word-of-mouth through the lens of museum tourism

This study investigates how tourist presence influences word-of-mouth (WOM) and measures whether authenticity significantly mediates presence and WOM in the Augmented Reality (AR) museum tourism experience. The survey data was collected from the AR-presented Palace Museum in China. The study found that presence positively influences tourists’ WOM, and authenticity positively mediated tourist prese

Birth weight and birth length affect future fracture risk differently in men and women

Summary: We wanted to determine if there are any associations between birth factors and adult fracture risk. For women only, shorter birth length was associated with lower relative fracture risk. For women and men, individuals who were long at birth as well as tall in adulthood had a substantially higher relative fracture risk. Purpose: We aimed to examine associations between birth anthropometry

Optimising Hydrogen Pump performance – Inducer design for cavitation mitigation

The aviation sector's contribution to global CO2 emissions requires the exploration of sustainable energy alternatives, with hydrogen emerging as a promising candidate. Despite their potential, hydrogen aircraft propulsion systems are not yet commercially viable, primarily due to technical challenges such as cavitation in hydrogen pumps. This study aims to analyse and optimise the design of hy

Free Recall Outperforms Story Recall in Associations with Plasma Biomarkers in Preclinical Alzheimer Disease

Background: A decline in episodic memory is one of the earliest cognitive characteristics of Alzheimer disease and memory tests are heavily featured in cognitive composite endpoints that are used to demonstrate treatment efficacy. Assessments of episodic memory can take many forms including free recall, associate learning, and paragraph or story recall. Plasma biomarkers of Alzheimer disease are n

Effect of acetylation on wood-water interactions studied by sorption calorimetry

Sorption of water has a profound effect on the material properties of wood. The uptake of water vapour in wood and other materials releases more heat than the condensation of vapour to liquid water. This excess energy provides insights to the interactions and energy state of the absorbed water molecules. Modification of wood by acetylation is a common way of altering the wood-water interactions; h

Environmental–Economic Analysis of Multi-Node Community Microgrid Operation in Normal and Abnormal Conditions—A Case Study of Indonesia

This paper presents a comprehensive analysis of the operation management of a multi-node community microgrid (MG), emphasizing power flow constraints and the integration of photovoltaic (PV) and battery systems. This study formulates MG operation management as a multi-objective optimal power flow problem, aiming to minimize costs (maximize profits) and emissions simultaneously. The multi-objective

Measurements of the switched gradient magnetic field in MRI : A closer look at some unintuitive spatial characteristics

Concomitant fields are the unwanted transverse components that arise when spatial encoding gradients are applied in MRI. We measured the changing gradient magnetic field at multiple locations inside the scanner and examined the internal distribution and linearity of the three vector components of the field. Our results illustrate some not-so-obvious spatial characteristics of the gradient field, w
