Characterisation of skin penetration pathways using stimulated Raman scattering microscopy.

Understanding the mechanisms governing the penetration of substances into the skin is crucial for the development of safe and effective topical drug delivery systems and skincare products. This study examined the partitioning of model permeants into human skin, by assessing six substances with diverse logP values. We employed stimulated Raman scattering (SRS) microscopy, an ambient, label-free optical imaging technique known for its ability to provide chemical distribution with subcellular resolution.

Dementia risk prediction modelling in low- and middle-income countries: current state of evidence.

Dementia is a leading cause of death and disability with over 60% of cases residing in low- and middle-income countries (LMICs). Therefore, new strategies to mitigate risk are urgently needed. However, despite the high burden of disease associated with dementia in LMICs, research into dementia risk profiling and risk prediction modelling is limited.

Dissociation between liver fat content and fasting metabolic markers of selective hepatic insulin resistance in humans.

Objective: Fasting hyperglycemia and hypertriglyceridemia are characteristic of insulin resistance (IR) and rodent work has suggested this may be due to selective hepatic IR, defined by increased hepatic gluconeogenesis and de novo lipogenesis (DNL), but this has not been shown in humans.

Design: Cross-sectional study in men and women across a range of adiposity.

Methods: Medication-free participants (n = 177) were classified as normoinsulinemic (NI) or hyperinsulinemic (HI) and as having low (LF) or high (HF) liver fat content measured by magnetic resonance spectroscopy.

Synthesis and characterization of amine-functionalized graphene as a nitric oxide-generating coating for vascular stents.

Drug-eluting stents are commonly utilized for the treatment of coronary artery disease, where they maintain vessel patency and prevent restenosis. However, problems with prolonged vascular healing, late thrombosis, and neoatherosclerosis persist; these could potentially be addressed via the local generation of nitric oxide (NO) from endogenous substrates. Herein, we develop amine-functionalized graphene as a NO-generating coating on polylactic acid (PLA)-based bioresorbable stent materials.

Retinal waves in adaptive rewiring networks orchestrate convergence and divergence in the visual system.

Spontaneous retinal wave activity shaping the visual system is a complex neurodevelopmental phenomenon. Retinal ganglion cells are the hubs through which activity diverges throughout the visual system. We consider how these divergent hubs emerge, using an adaptively rewiring neural network model.

The impact of the nursing work environment on compassion fatigue: The mediating role of general self-efficacy.

Aim: To explore the interplay between the perceived nursing work environment, general self-efficacy, and compassion fatigue among registered nurses in Chinese hospitals.

Background: Compassion fatigue emerges as a significant occupational stress response globally, with the nursing work environment being a pivotal influencer. There is a knowledge gap in understanding how the nursing work environment and general self-efficacy interrelate to affect compassion fatigue, particularly among Chinese nurses.

Understanding the needs of children and young people with food hypersensitivities: A qualitative study.

Background: Research has highlighted the psychosocial impact of living with food hypersensitivities (FHS) on children and young people (CYP). However, there is a paucity of qualitative data from CYP themselves in terms of the support they would like to receive to improve their psychological well-being.

Objective: To further understand firsthand the experiences of CYP with FHS including the challenges they face and to inform structural changes in how their psychological well-being is supported.

External validation of the DIAFORA system to predict lower-extremity amputations in a prospective Danish cohort.

Aim: A diabetes-related foot ulcer (DFU) is a major risk factor for lower-extremity amputation (LEA). To help clinicians predict the risk of LEA in people with DFU, the Diabetic Foot Risk Assessment (DIAFORA) system was developed but has never been externally validated.

Methods: In this study, 317 people presenting with a new DFU were included.

Unveiling the Performance of Co-Assembled Hybrid Nanocarriers: Moving towards the Formation of a Multifunctional Lipid/Random Copolymer Nanoplatform.

Despite the appealing properties of random copolymers, the use of these biomaterials in association with phospholipids is still limited, as several aspects of their performance have not been investigated. The aim of this work is the formulation of lipid/random copolymer platforms and the comprehensive study of their features by multiple advanced characterization techniques. Both biomaterials are amphiphilic, including two phospholipids (1,2-dioctadecanoyl-sn-glycero-3-phosphocholine (DSPC), 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC)) and a statistical copolymer of oligo (ethylene glycol) methyl ether methacrylate (OEGMA) and 2-(diisopropylamino) ethyl methacrylate (DIPAEMA).

In Silico Modeling of Stress Distribution in the Diseased Ankle Joint.

Osteoarthritis is a feature of the aging process. Here, we adopted in silico 2D finite element modeling (FEM) for the simulation of diseased ankle joints. We delved into the influence of body weight intensity on the stress distribution caused by subchondral cysts imitating degenerative age-related arthritic changes.

A Novel Phage against Bearing a Unique Gene of Intergeneric Origin.

Association of maternal thyroglobulin with gestational thyroid function and offspring IQ and brain morphology.

Background: Low maternal urinary iodine concentration (UIC) during pregnancy is associated with adverse offspring neurodevelopment. Thyroglobulin (Tg) has been suggested as a more sensitive biomarker than UIC of long-term iodine status, but associations of Tg with neurodevelopment and the possible mediating role of thyroid function remain unknown.

Aim: To study whether maternal Tg is associated with i) maternal and newborn thyroid function and ii) offspring IQ and brain morphology.

Stealthy and hyperuniform isotropic photonic band gap structure in 3D.

In photonic crystals, the propagation of light is governed by their photonic band structure, an ensemble of propagating states grouped into bands, separated by photonic band gaps. Due to discrete symmetries in spatially strictly periodic dielectric structures their photonic band structure is intrinsically anisotropic. However, for many applications, such as manufacturing artificial structural color materials or developing photonic computing devices, but also for the fundamental understanding of light-matter interactions, it is of major interest to seek materials with long range nonperiodic dielectric structures which allow the formation of photonic band gaps.

Exploring vision transformers for classifying early Barrett's dysplasia in endoscopic images: A pilot study on white-light and narrow-band imaging.

Background And Aim: Various deep learning models, based on convolutional neural network (CNN), have been shown to improve the detection of early esophageal neoplasia in Barrett's esophagus. Vision transformer (ViT), derived from natural language processing, has emerged as the new state-of-the-art for image recognition, outperforming predecessors such as CNN. This pilot study explores the use of ViT to classify the presence or absence of early esophageal neoplasia in endoscopic images of Barrett's esophagus.

Can-and should-automaticity be self-reported using a single item? A secondary analysis of 16 datasets.

Understanding the influence of habit on health behaviour, or the formation or disruption of health habits over time, requires reliable and valid measures of automaticity. The most used measure, the Self-Report Behavioural Automaticity Index (SRBAI; derived from the Self-Report Habit Index [SRHI]), comprises four items, which may be impractical in some research contexts. Responding to demand from fellow researchers, this study sought to identify whether and which single items from the SRBAI adequately detect hypothesised effects of automaticity, via secondary analysis of 16 datasets, incorporating 16,838 participants and seven different behaviours.

A multi-national survey to identify health professionals' opinions for the appropriate frequency of urine output monitoring in post-operative patients.

Urine output is an important clinical measurement and oliguria may highlight the development of acute kidney injury (AKI) earlier than serum creatinine (sCr). Despite the importance of urine output monitoring, there are no definitive guidelines or recommendations for best practice. A survey was sent to healthcare professionals with a specialist interest in AKI to gather opinions of what constitutes a good standard of urine output monitoring and by corollary missed care, post- major surgery.

Exploring sex differences in cardiac interoceptive accuracy using the phase adjustment task.

Previous evidence suggests males and females differ with respect to interoception-the processing of internal bodily signals-with males typically outperforming females on tasks of interoceptive accuracy. However, interpretation of existing evidence in the cardiac domain is hindered by the limitations of existing tools. In this investigation, we pooled data from several samples to examine sex differences in cardiac interoceptive accuracy on the phase adjustment task, a new measure that overcomes several limitations of the existing tools.
