Embed systemic equity throughout industrial ecology applications: How to address machine learning unfairness and bias.

Recent calls have been made for equity tools and frameworks to be integrated throughout the research and design life cycle -from conception to implementation-with an emphasis on reducing inequity in artificial intelligence (AI) and machine learning (ML) applications. Simply stating that equity should be integrated throughout, however, leaves much to be desired as industrial ecology (IE) researchers, practitioners, and decision-makers attempt to employ equitable practices. In this forum piece, we use a critical review approach to explain how socioecological inequities emerge in ML applications across their life cycle stages by leveraging the food system.

Towards green, scalable peptide synthesis: leveraging DEG-crosslinked polystyrene resins to overcome hydrophobicity challenges.

Diethylene glycol dimethacrylate (DEG)-crosslinked polystyrene (PS) resin offers a promising alternative to traditional divinyl benzene (DVB)-PS resin for solid-phase peptide synthesis (SPPS), particularly for challenging sequences with hydrophobic or bulky amino acids. DEG-PS resin's reduced hydrophobicity and enhanced flexibility improve synthesis efficiency, yielding peptides up to 28 residues with higher purities and yields compared to DVB-PS. In various syntheses, DEG-PS outperformed DVB-PS resin, with higher purities and yields for challenging peptides such as ABC analogue (73.

Metallic sealants increase flux and change selectivity in supported molten-salt membranes.

Metallic sealants are widely used with high-temperature membranes. Here we show that their use in supported molten-salt membranes results in order-of-magnitude differences in CO flux and introduces O co-permeation. The 'short-circuiting' effect they introduce has important implications for the design of future experiments, and the interpretation of past work.

Revisiting the Atrioventricular Conduction Axis for the 21st Century.

In this review, we summarise the ongoing debate surrounding the anatomy of the atrioventricular conduction axis and its relevance to pacing. We highlight previous disagreements and emphasise the importance of understanding the anatomical location of the axis. We give credit and support to the initial descriptions by His and Tawara, in particular their attention to the relationship of the atrioventricular conduction axis with the membranous septum.

A logic-based resilience metric for water resource recovery facilities.

This study develops quantifiable metrics to describe the resilience of Water Resource Recovery Facilities (WRRFs) under extreme stress events, including those posed by long-term challenges such as climate change and population growth. Resilience is the ability of the WRRFs to withstand adverse events while maintaining compliance or an operational level of service. Existing studies lack standardised resilience measurement methods.

Stress granules formation in HEI-OC1 auditory cells and in H4 human neuroglioma cells secondary to cisplatin exposure.

Stress granules (SGs) are highly dynamic micromolecular membraneless condensates that generate in cells subjected to stress. Formed from pools of untranslating messenger ribonucleoproteins (RNP), SGs dynamics constitute vital processes essential for cell survival. Here, we investigate whether established cytotoxic agents, such as the platinum-based chemotherapeutic agent cisplatin and the aminoglycoside antibiotic gentamicin, elicit SG formation in the House Ear Institute-Organ of Corti-1 (HEI-OC1) auditory cell line, H4 human neuroglioma cells and HEK-293T human embryonic kidney cells.

Avoiding "a piece of paper on the wall that everyone ignores": A qualitative study on the barriers for implementing open fracture guidelines.

Background: Ortho-plastic evidence-based clinical guidelines for open fractures have demonstrated to standardise care and improve outcomes for patients admitted following lower extremity trauma. Despite its benefits, very few countries have introduced such guidance. The aim of this study was to explore the attitudes, barriers and limitations to the development and implementation of guidelines for lower limb open fractures METHODS: Twelve renowned orthopaedic and plastic surgeons, based in countries with no guidelines at present, underwent semi-structured interviews.

Invasive Versus Conservative Strategy in Older Adults ≥75 Years of Age With Non-ST-segment-Elevation Acute Coronary Syndrome: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Background: Older adults with non-ST-segment-elevation acute coronary syndrome are less likely to undergo an invasive strategy compared with younger patients. Randomized controlled trials traditionally exclude older adults because of their high burden of geriatric conditions.

Methods And Results: We searched for randomized controlled trials comparing invasive versus medical management or a selective invasive (conservative) strategy for older patients (age≥75 years) with non-ST-segment-elevation acute coronary syndrome.

The genus Wagler, 1828 comprises 20 species of semiaquatic snakes. It is mostly distributed in the cis-Andean region of South America, with only two trans-Andean species (, ). is endemic to Colombia and occurs through most of the trans-Andean region.

Suction use in ureterorenoscopy: A systematic review and meta-analysis of comparative studies.

Objectives: Ureterorenoscopy is seeing a bloom of technological advances, one of which is incorporating suction. The objective of this study is to systematically review existing literature regarding suction use in rigid and flexible ureterorenoscopy and perform meta-analysis of studies comparing suction versus no suction ureteroscopy or mini percutaneous nephrolithotomy (PCNL).

Methods: A literature search was performed (November 2023) in MEDLINE, Embase and Cochrane CENTRAL.

Are restricted and repetitive behaviours in two- and six-year-olds associated with emotional and behavioural difficulties?

Background: Restricted and repetitive patterns of behaviour (RRBs) serve an adaptive role in development. Elevated levels of RRBs beyond the early years, however, are associated with poorer outcome in language, cognition, and wellbeing, and are seen across a range of neurodevelopmental conditions. This study aimed to characterize the association of distinct RRB subtypes at two and six years of age, with internalising and externalising difficulties in a community sample of children.

Effects of Climate, Soil, Topography and Disturbance on Liana Prevalence.

Lianas (woody vines and climbing monocots) are increasing in abundance in many tropical forests with uncertain consequences for forest functioning and recovery following disturbances. At a global scale, these increases are likely driven by disturbances and climate change. Yet, our understanding of the environmental variables that drive liana prevalence at regional scales is incomplete and geographically biased towards Latin America.

Optimizing ionic transport in argyrodites: a unified view on the role of sulfur/halide distribution and local environments.

Understanding diffusion mechanisms in solid electrolytes is crucial for advancing solid-state battery technologies. This study investigates the role of structural disorder in Li PS Br argyrodites using molecular dynamics, focusing on the correlation between key structural descriptors and Li-ion conductivity. Commonly suggested parameters, such as configurational entropy, bromide site occupancy, and bromine content, correlate with Li-ion diffusivity but do not consistently explain conductivity trends.

Optimising recovery of DNA from minimally invasive sampling methods: Efficacy of buccal swabs, preservation strategy and DNA extraction approaches for amphibian studies.

Studies in evolution, ecology and conservation are increasingly based on genetic and genomic data. With increased focus on molecular approaches, ethical concerns about destructive or more invasive techniques need to be considered, with a push for minimally invasive sampling to be optimised. Buccal swabs have been increasingly used to collect DNA in a number of taxa, including amphibians.

Anatomical Ablation of the Atrioventricular Node.

Background: Atrioventricular (AV) conduction ablation has been achieved by targeting the area of penetration of the conduction axis as defined by recording a His bundle potential. Ablation of the His bundle may reduce the possibility of a robust junctional escape rhythm. It was hypothesised that specific AV nodal ablation is feasible and safe.

Vanadium redox flow batteries have applications for large-scale electricity storage. This paper reports the influence of carbon structural characteristics of sustainable walnut shell-derived carbons in carbon/polyvinylidene fluoride composite electrodes on vanadium redox reactions. Pyrolysis, gasification, and chemical treatment procedures were used to modify the structural characteristics of carbons.

Antibiotic origami: selective formation of spirotetronates in abyssomicin biosynthesis.

The abyssomicins are a structurally intriguing family of bioactive natural products that include compounds with potent antibacterial, antitumour and antiviral activities. The biosynthesis of the characteristic abyssomicin spirotetronate core occurs an enzyme-catalysed intramolecular Diels-Alder reaction, which proceeds one of two distinct stereochemical pathways to generate products differing in configuration at the C15 spirocentre. Using the purified spirotetronate cyclases AbyU (from abyssomicin C/atrop-abyssomicin C biosynthesis) and AbmU (from abyssomicin 2/neoabyssomicin biosynthesis), in combination with synthetic substrate analogues, here we show that stereoselectivity in the spirotetronate-forming [4 + 2]-cycloaddition is controlled by a combination of factors attributable to both the enzyme and substrate.

Understanding and treating diabetic foot ulcers: Insights into the role of cutaneous microbiota and innovative therapies.

Background: Notoriously known as the silent pandemic, chronic, non-healing diabetic foot ulcers (DFUs), pose a significant rate of incidence for amputation and are a major cause of morbidity. Alarmingly, the treatment and management strategies of chronic wounds represent a significant economic and health burden as well as a momentous drain on resources with billions per annum being spent in the US and UK alone. Defective wound healing is a major pathophysiological condition which propagates an acute wound to a chronic wound, further propelled by underlying conditions such as diabetes and vascular complications which are more prevalent amongst the elderly.

Characterising glycosaminoglycans in human breastmilk and their potential role in infant health.

Human breastmilk is composed of many well researched bioactive components crucial for infant nutrition and priming of the neonatal microbiome and immune system. Understanding these components gives us crucial insight to the health and wellbeing of infants. Research surrounding glycosaminoglycans (GAGs) previously focused on those produced endogenously; however, recent efforts have shifted to understanding GAGs in human breastmilk.

A perfectly imperfect engine: Utilizing the digital twin paradigm in pulmonary hypertension.

Pulmonary hypertension (PH) is a severe medical condition with a number of treatment options, the majority of which are introduced without consideration of the underlying mechanisms driving it within an individual and thus a lack of tailored approach to treatment. The one exception is a patient presenting with apparent pulmonary arterial hypertension and shown to have vaso-responsive disease, whose clinical course and prognosis is significantly improved by high dose calcium channel blockers. PH is however characterized by a relative abundance of available data from patient cohorts, ranging from molecular data characterizing gene and protein expression in different tissues to physiological data at the organ level and clinical information.
