Mechanical and thermal responsive chiral photonic cellulose hydrogels for dynamic anti-counterfeiting and optical skin.

Dynamic responsive structural colored materials have drawn increased consideration in a wide range of applications, such as colorimetric sensors and high-safety tags. However, the sophisticated interactions among the individual responsive parts restrict the advanced design of multimodal responsive photonic materials. Inspired by stimuli-responsive color change in chameleon skin, a simple and effective photo-crosslinking strategy is proposed to construct hydroxypropyl cellulose (HPC) based hydrogels with multiple responsive structured colors.

Selective diet induced nutritional optic neuropathy in developmentally normal children.

Purpose: Nutritional deficiencies in developed countries are a rare but potentially intervenable cause of optic neuropathy in pediatric populations. To date, much of the literature on nutritional optic neuropathy has focused on children with developmental delay, however, a growing body of evidence supports other underreported risk factors.

Observations: We describe three pediatric patients with normal neurodevelopment, who presented with decreased vision and were subsequently found to have optic neuropathy attributed to vitamin deficiencies, predominantly vitamin B12.

Safety and Efficacy of Remote Ischemic Conditioning in Patients With Intravenous Thrombolysis: The SERIC-IVT Trial.

Lifestyle Medicine and Vasomotor Symptoms: An Analytic Review.

This paper is an literature evaluation of the treatments based on the 6 pillars of Lifestyle Medicine (nutrition, physical activity, restorative sleep, stress management, positive social connection, and avoidance of risky substances) to improve vasomotor symptoms. Main findings were: (1) the Mediterranean diet and other plant-forward approaches may effectively reduce vasomotor symptoms; (2) stress can directly impact menopausal symptoms by increasing the frequency and intensity of hot flashes and other symptoms; (3) the incidence of sleep disturbances are high during the menopause transition; (4) evidence on the impact of physical activity and exercise on vasomotor symptoms is mixed, although moderate activity and strength training may be better for vasomotor symptom optimization than vigorous exercise and part of a healthy aging process; (5) evidence on the impact of social support on VMS is mixed with some studies suggesting benefit; and (6) evidence on the impact of risky substances is mixed but appears stronger for the effects of tobacco cessation than for alcohol cessation. In summary, while there is a variety of quality of evidence depending on the pillar, lifestyle medicine may be generally considered to improve vasomotor symptoms for patients that cannot use or decline hormone therapy.

Endoplasmic Reticulum Stress in Bronchopulmonary Dysplasia: Contributor or Consequence?

Bronchopulmonary dysplasia (BPD) is the most common complication of prematurity. Oxidative stress (OS) and inflammation are the major contributors to BPD. Despite aggressive treatments, BPD prevalence remains unchanged, which underscores the urgent need to explore more potential therapies.

Skeletal muscle density as a new predictor of abdominal infection in abdominal trauma patients.

Background And Aims: Skeletal muscle density (SMD) is a valuable prognostic indicator in various conditions such as cancer, liver cirrhosis. Yet, the connection between SMD and intra-abdominal infection in individuals who have suffered abdominal injuries is still unclear. The purpose of this research is to examine how well SMD can predict intra-abdominal infection in patients who have suffered abdominal trauma.

Temporal Dynamics of Oxidative Stress and Inflammation in Bronchopulmonary Dysplasia.

Bronchopulmonary dysplasia (BPD) is the most common lung complication of prematurity. Despite extensive research, our understanding of its pathophysiology remains limited, as reflected by the stable prevalence of BPD. Prematurity is the primary risk factor for BPD, with oxidative stress (OS) and inflammation playing significant roles and being closely linked to premature birth.

Correlation study of multiple inflammatory indices and vertebral compression fracture: A cross-sectional study.

Background: Vertebral compression fractures (VCFs) are prevalent in patients with osteoporosis and pose significant health risks. Although chronic low-grade inflammation plays a crucial role in the pathogenesis of osteoporosis, the relationship between various inflammatory indices and the occurrence of fractures remains unclear.

Objective: This study aims to evaluate the correlation between multiple inflammatory indices, neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammatory index (SII), and systemic inflammatory response index (SIRI), and VCFs, to explore the significance of these indices in clinical application.

Intravenous fluorescein overdose in a child undergoing fluorescein angiography.

Fluorescein angiography is a fluorescent dye-based imaging procedure, most commonly indicated in the pediatric setting to evaluate peripheral retinal vascular lesions. Fluorescein dye is organic, water soluble, and largely excreted renally, with a reassuring safety profile at therapeutic doses. While toxicity with intrathecal overdose has been reported, the effect of intravenous exposure to supratherapeutic levels has not been previously documented in the literature.

Preparation of Coir Cellulose Nanofibers by Peroxyformic Acid Method and Their Application in Reinforced PVA Composite Films.

To increase the value of waste coconut shells and further broaden their use by biorefining, a milder and greener method to prepare cellulose nanofibers (CCNFs) was developed. The CCNFs were separated from coir fibers by using peroxyformic acid and alkali treatment in combination with high-power ultrasonication. The basic properties of the CCNFs were comprehensively evaluated using scanning and transmission electron microscopy, spectroscopy, diffraction, and thermogravimetric techniques.

Monobutyl phthalate (MBP) is the primary active metabolite of dibutyl phthalate (DBP), the key plasticizer component. A substantial body of evidence from studies conducted on both animals and humans indicates that MBP exposure could result in harmful impacts on toxicity pathways. In addition, it can seriously affect human and animal reproductive health.

Design and Synthesis of a Robust and Multifunctional Superhydrophobic Coating with a Three-Dimensional Network Structure on a Paper-Based Material.

A fundamental challenge in artificial superhydrophobic papers is their poor resistance to mechanical abrasion, which limits their practical application in different fields. Herein, a robust and multifunctional superhydrophobic paper is successfully fabricated via a facile spraying method by combining silver nanowires and fluorinated titania nanoparticles through a common paper sizing agent (alkyl ketene dimer) onto paper. It is shown that the surface of the paper-based material presents a three-dimensional network structure due to the cross-linking of silver nanowires with a high aspect ratio.

Decreased Liver Kinase B1 Expression and Impaired Angiogenesis in a Murine Model of Bronchopulmonary Dysplasia.

Bronchopulmonary dysplasia (BPD) is characterized by impaired lung alveolar and vascular growth. We investigated the hypothesis that neonatal exposure to hyperoxia leads to persistent BPD phenotype caused by decreased expression of liver kinase B1 (LKB1), a key regulator of mitochondrial function. We exposed mouse pups from Postnatal Day (P)1 through P10 to 21% or 75% oxygen.
