The realization of antipulverization electrode structures, especially using low-carbon-content anode materials, is crucial for developing high-energy and long-life lithium-ion batteries (LIBs); however, this technology remains challenging. This study shows that SnO2 triple-shelled hollow superstructures (TSHSs) with a low carbon content (4.83%) constructed by layer-by-layer assembly of various nanostructure units can withstand a huge volume expansion of ≈231.8% and deliver a high reversible capacity of 1099 mAh g(-1) even after 1450 cycles...

β-(1,3)-Glucan, the major fungal cell wall component, ramifies through β-(1,6)-glycosidic linkages, which facilitates its binding with other cell wall components contributing to proper cell wall assembly. Using Saccharomyces cerevisiae as a model, we developed a protocol to quantify β-(1,6)-branching on β-(1,3)-glucan. Permeabilized S. cerevisiae and radiolabeled substrate UDP-((14)C)glucose allowed us to determine branching kinetics. A screening aimed at identifying deletion mutants with reduced branching among them revealed only two, the bgl2Δ and gas1Δ mutants, showing 15% and 70% reductions in the branching, respectively, compared to the wild-type strain...

Organelles without membranes are found in all types of cells and typically contain RNA and protein. RNA and protein are the constituents of ribosomes, one of the most ancient cellular structures. It is reasonable to propose that organelles without membranes preceded protocells and other membrane-bound structures at the origins of life. Such membraneless organelles would be well sheltered in the spaces between mica sheets, which have many advantages as a site for the origins of life.

Biomarkers are widely used in ecotoxicology as indicators of exposure to toxicants. However, their ability to provide ecologically relevant information remains controversial. One of the major problems is understanding if the measured responses are determined by stress factors or lie within the natural variability range. In a previous work, the natural variability of enzymatic levels in invertebrates sampled in pristine rivers was proved to be relevant across both space and time. In this work, the experimental design was improved by considering different life stages of the selected taxa and by measuring more environmental parameters...

Based on available literature, ecology and economy of LED (light emitting diode) lights in plant foods production were assessed and compared to HPS (high pressure sodium) and CFL (compact fluorescent light) lamps. The assessment summarises that LEDs are superior compared to other lamp types. LEDs are ideal in luminous efficiency, life span and electricity usage. Mercury, carbon dioxide and heat emissions are also lowest in comparison to HPS and CFL lamps. This indicates that LEDs are indeed economic and eco-friendly lighting devices...

INTRODUCTION: Treatment decisions in elderly patients with traumatic brain injury (TBI) are mainly determined by trauma severity and patient age. The aim of this study was to explore personal preferences of potential patients regarding life-prolonging neurosurgical interventions by interviewing ambulatory, autonomous elderly people. METHODS: One hundred consecutive patients older than 75 years frequenting the outpatient clinic of the Department of Neurosurgery were interviewed about their attitudes regarding the hypothetical case of an 81-year-old patient with TBI and a space-occupying acute subdural hematoma (aSDH) using a 21-point questionnaire...

The voltage-dependent anion channel 1 (VDAC1), an outer mitochondria membrane protein, functions as a mitochondrial governor, controlling transport of metabolites in and out of the mitochondria and energy production, while also coordinating glycolysis and oxidative phosphorylation (OXPHOS). . VDAC1 plays a key role in mitochondria-mediated apoptosis by functioning in the release of apoptotic proteins located in the inter-membranal space (IMS) and due to its association with pro- and anti-apoptotic proteins...

Habitat restoration is a key measure to counteract negative impacts on biodiversity from habitat loss and fragmentation. To assess success in restoring not only biodiversity, but also functionality of communities, we should take into account the re-assembly of species trait composition across taxa. Attaining such functional restoration would depend on the landscape context, vegetation structure, and time since restoration. We assessed how trait composition of plant and pollinator (bee and hoverfly) communities differ between abandoned, restored (formerly abandoned) or continuously grazed (intact) semi-natural pastures...

Patients with hand muscular atrophy due to damage of the ulnar nerve could be stigmatized for their appearance. Unsatisfactory results in the attempt to correct the atrophy are reported in the literature. Fat grafting is an autologous and easily obtainable graft, antigenic response is very unlikely, it does not require any special material, and the procedure has a low cost. The technique of autologous fat grafting by using fat block, to remodel the first interdigital space, is useful and safe in correcting muscle atrophy of the first interdigital space caused by the injury of the ulnar nerve...

REVIEW
Magdalini Papadaki
For the nascent field of advanced therapies, collaboration will be a game-changer, turning scientific progress that was once unimaginable into transformative medical practice. Despite promise for lifelong management and even cure of disease, skepticism remains about the feasibility of their delivery to patients, fueling investment risks. With the potential for long-term effectiveness in need of frequent reassessment, current approaches to predict real-life drug performance bear little relevance, necessitating novel and iterative schemes to monitoring the benefit-risk profiles throughout the life span of advanced therapies...

Detection of grapes in real-life images is a serious task solved by researchers dealing with precision viticulture. In the case of white wine varieties, grape detectors based on SVMs classifiers, in combination with a HOG descriptor, have proven to be very efficient. Simplified versions of the detectors seem to be the best solution for practical applications. They offer the best known performance versus time-complexity ratio. As our research showed, a conversion of RGB images to grayscale format, which is implemented at an image preprocessing level, is ideal means for further improvement of performance of the detectors...

Phosphatidylserine decarboxylase 1 (Psd1p), an ancient enzyme that converts phosphatidylserine to phosphatidylethanolamine in the inner mitochondrial membrane, must undergo an autocatalytic self-processing event to gain activity. Autocatalysis severs the protein into a large membrane anchored β subunit that non-covalently associates with the small α subunit on the intermembrane space side of the inner membrane. Here, we determined that a temperature sensitive (ts) PSD1 allele is autocatalytically impaired and that its fidelity is closely monitored throughout its life cycle by multiple mitochondrial quality control proteases...

We present 1,003 reference genomes that were sequenced as part of the Genomic Encyclopedia of Bacteria and Archaea (GEBA) initiative, selected to maximize sequence coverage of phylogenetic space. These genomes double the number of existing type strains and expand their overall phylogenetic diversity by 25%. Comparative analyses with previously available finished and draft genomes reveal a 10.5% increase in novel protein families as a function of phylogenetic diversity. The GEBA genomes recruit 25 million previously unassigned metagenomic proteins from 4,650 samples, improving their phylogenetic and functional interpretation...
