Based on the innate sensitivity of cell to substrate topographical cues, modulating cell-directed growth behavior is crucial for promoting tissue repair and reconstruction. Although photolithography technology has been extensively employed to fabricate a variety of anisotropic patterned structures to guide cell growth, it remains a great challenge to design high-resolution micro/nano hierarchical structures directly onto medical titanium (Ti)-based implants. Herein, we present a rapid, reliable and reproducible approach combining photolithography and hydrothermal technology to construct a micro/nano hierarchical structure including anisotropic micro-strips and a porous structure composed of TiO nanotubes features.

Nanoengineering polar oxide films have attracted great attention in energy storage due to their high energy density. However, most of them are deposited on thick and rigid substrates, which is not conducive to the integration of capacitors and applications in flexible electronics. Here, an alternative strategy using van der Waals epitaxial oxide dielectrics on ultra-thin flexible mica substrates is developed and increased the disorder within the system through high laser flux.

Ferroptosis is an iron-dependent cell death form characterized by reactive oxygen species (ROS) overgeneration and lipid peroxidation. Myricetin, a flavonoid that exists in numerous plants, exhibits potent antioxidant capacity. Given that iron accumulation and ROS-provoked dopaminergic neuron death are the two main pathological hallmarks of Parkinson's disease (PD), we aimed to investigate whether myricetin decreases neuronal death through suppressing ferroptosis.

Background: The association between body mass index (BMI) and rapid eye-movement (REM) sleep-related behavioral disorder (RBD) in Parkinson's disease (PD) remains unknown. Our study was to investigate the association of BMI with RBD in PD patients.

Methods: In this cross-sectional study, a total of 1,115 PD participants were enrolled from Parkinson's Progression Markers Initiative (PPMI) database.

Introduction: With the aging of the population in China, the prevalence of atopic dermatitis (AD) is high in elderly patients. These patients usually have more comorbidities and they need more effective and safer treatments. Dupilumab is an anti-interleukin-4 (IL-4) receptor monoclonal antibody which was approved for the treatment of moderate-to-severe AD.

Background And Objective: The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor, which is involved in the pathogenesis of a variety of skin diseases such as atopic dermatitis (AD). In this study, we aimed to study the AhR-expressing cells in T helper 17 (Th17), T helper 22 (Th22), regulatory T cells (Treg) and B cells in peripheral blood and in AD skin lesions.

Methods: Twenty AD patients defined according to the Chinese criteria of atopic dermatitis and eighteen healthy subjects were included in our study.

Article Synopsis
  • Scientists found that mango peels have important substances called carotenoids and polyphenols that help fight off bad stuff in our body, with amounts measured in mg/g.* -
  • The study showed that these two substances work together, making carotenoids even better at staying fresh and healthy.* -
  • They discovered that certain kinds of carotenoids and polyphenols, like lutein and gallic acid, especially team up well to boost their effectiveness, which could help create stronger natural products.*

Clinical observation indicates that exercise capacity, an important determinant of survival in patients with congenital heart disease (CHD), is most decreased in children with reduced pulmonary blood flow (RPF). However, the underlying mechanism remains unclear. Here, we obtained human RPF lung samples from children with tetralogy of Fallot as well as piglet and rat RPF lung samples from animals with pulmonary artery banding surgery.

Background: Bullous pemphigoid (BP) and atopic dermatitis (AD) are both type 2 inflammatory skin diseases with similar clinical features. Thymic stromal lymphopoietin (TSLP) is an epithelial-derived cytokine which is upregulated in AD. However, the expression of TSLP in BP and the correlation between TSLP and inflammatory infiltrations have not been fully studied.

A case of new onset of severe plaque psoriasis following COVID-19 vaccination was reported. A 63-year-old woman presented with multiple plaques for 2 months after the second dose of COVID-19 vaccination. Dermatological examination revealed diffuse erythematous papules and plaques on trunk and limbs.

Ferroelectric solid solutions with composition near the morphotropic phase boundary (MPB) have gained extensive attention recently due to their excellent ferroelectric and piezoelectric properties. Here, we have demonstrated a strategy to realize the controllable preparation of BiFeO-BaTiO (BF-BT) epitaxial films near the MPB. A series of high-quality BF-BT films were fabricated by pulsed laser deposition via adjusting oxygen partial pressure (PO) using a BF-BT ceramic target.

Engineered cartilage derived from mesenchymal stromal cells (MSCs) always fails to maintain the cartilaginous phenotype in the subcutaneous environment due to the ossification tendency. Vascular invasion is a prerequisite for endochondral ossification during the development of long bone. As an oral antitumor medicine, Inlyta (axitinib) possesses pronounced antiangiogenic activity, owing to the inactivation of the vascular endothelial growth factor (VEGF) signaling pathway.

Background: The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor, which is critically involved in the pathogenesis of a variety of skin diseases. The aim of this study was to detect AhR and its downstream regulators including cytochrome P450 (CYP1A1), AhR nuclear translocation (ARNT), and aryl hydrocarbon receptor repressor (AhRR) in serum, peripheral blood mononuclear cells (PBMCs), and skin lesions in patients with atopic dermatitis (AD).

Methods: Twenty-nine AD patients defined according to the criteria of Hanifin and Rajka and Chinese criteria of AD were included.

Pyoderma gangrenosum (PG) is a rare ulcerating inflammatory neutrophilic dermatosis. Different clinical manifestations have been described, including ulcerative, pustular and bullous, and vegetative variants. Classic PG usually occurs on the lower extremities (~70% of cases) but can also involve the hands, head, neck, and scrotum.
