Psoriasis is a chronic, relapsing, inflammatory skin disease that is caused by the immune system. Amygdalin possesses immune-modulating and anti-inflammatory effects. To explore the possible effects of amygdalin on psoriasis and its pathogenesis of action, we examined the effects of amygdalin on imiquimod-induced psoriasis, tape-stripping-induced skin barrier disruption, and investigated the potential mechanism of action in vitro.

A photonic crystal (PC) is an optical microstructure with an adjustable dielectric constant. The PC sensor was deemed a powerful tool for gas molecule detection due to its excellent sensitivity, stability, online use and tailorable optical performance. The detection signals are generated by monitoring the changes of the photonic band gap when the sensing behavior occurs.

Article Synopsis
  • - Psoriasis is a common, chronic skin disease that negatively impacts both physical and mental health, leading to significant suffering and high health care costs; the treatment PSORI-CM01 has shown effectiveness over years of clinical use, though its exact mechanisms are not well understood.
  • - Research involving network pharmacology and microRNA profiling identified that PSORI-CM01 improves psoriasis symptoms by regulating autophagy, apoptosis, and inflammatory responses, specifically affecting key microRNAs like miR-20a-3p and miR-3184-3p.
  • - Experimental findings confirmed that PSORI-CM01 treatment leads to changes in gene expression linked to these microRNAs, enhancing autophagy and affecting pathways related to inflammation and cell growth

Mustard gas, a representative of blister agents, poses a severe threat to human health. Although the structure of 2-chloroethyl ethyl sulfide (2-CEES) is similar to mustard gas, 2-CEES is non-toxic, rendering it a commonly employed simulant in related research. ZnFeO-based semiconductor gas sensors exhibit numerous advantages, including structural stability, high sensitivities, and easy miniaturization.

Background: Psoriasis is an immune-mediated chronic inflammatory skin disease. Current research suggests that the long-term persistence and recurrence of psoriasis are closely related to the feedback loop formed between keratinocytes and immune cells, especially in Th 17 or DC cells expressing CCR6. CCL20 is the ligand of CCR6.

Background: Obesity and dyslipidemia, major global health concerns, have been linked to psoriasis, but previous studies faced methodological limitations and their shared genetic basis remains unclear. This study examines various obesity-related and lipidemic traits as potential contributors to psoriasis development, aiming to clarify their genetic associations and potential causal links.

Methods: Summary statistics from genome-wide association studies (GWAS) conducted for obesity-related traits (body mass index (BMI), waist-to-hip ratio (WHR), and waist-to-hip ratio adjusted for the body mass index (WHRBMI)) and lipidemic traits (high-density lipoprotein (HDL), LDL, triglyceride (TG), total Cholesterol (TC), apolipoprotein A1 (apoA1), apolipoprotein B (apoB), and apolipoprotein E (apoE)) and psoriasis, all in populations of European ancestry, were used.

The utilization of microalgae for both removing phthalate esters (PAEs) from wastewater and producing bioenergy has become a popular research topic. However, there is a lack of studies comparing the effectiveness of different types of microalgae in removing these harmful compounds. Therefore, the present study aimed to evaluate and compare the efficiency of various processes, such as hydrolysis, photolysis, adsorption, and biodegradation, in removing diisobutyl phthalate (DiBP) using six different species of microalgae.

Rapid economic development has increased the accumulation of dissolved organic matter (DOM) and heavy metals in aquatic environments. In addition, Microcystis aeruginosa can cause the outbreak of cyanobacteria bloom and can produce microcystin, which poses a threat to human water safety. Therefore, this study analyzed the biochemical and molecular assays of DOM (0, 1, 3, 5, 8, 10 mg C L) extracted from four different sources on the toxicity of cadmium (Cd) to M.

  • Agroecosystems contribute significantly to nitric oxide (NO) emissions, with upland cropping systems emitting more NO than paddy fields, but uncertainties about these emissions and their regulating factors remain.
  • Various field studies have been conducted to analyze NO emissions and potential mitigation strategies, which form the basis of this study's meta-analysis.
  • Results from 49 peer-reviewed references revealed that NO emissions varied across different cropping systems in China, correlating positively with nitrogen input in certain systems while showcasing a need for better management practices to mitigate emissions.

Due to its ornamental, edible, and medicinal value, Hemerocallis has been historically loved and used in China. However, the current understanding of the aromatic profiles of this flower is rather limited. This work aimed to evaluate and classify the aromatic profiles of Hemerocallis flowers from 10 cultivars, the volatiles of which were analyzed using solid-phase microextraction-gas chromatography-mass spectrometry.

Objectives: To develop and evaluate an artificial intelligence (AI) system that can automatically calculate the glomerular filtration rate (GFR) from dynamic renal imaging without manually delineating the regions of interest (ROIs) of kidneys and the corresponding background.

Methods: This study was a single-center retrospective analysis of the data of 14,634 patients who underwent Tc-DTPA dynamic renal imaging. Two systems based on convolutional neural networks (CNN) were developed and evaluated: sGFR predicts the radioactive counts of ROIs and calculates GFR using the Gates equation and sGFR directly predicts GFR from dynamic renal imaging without using other information.

Psoriasis is a chronic proliferative skin disorder characterised by abnormal epidermal differentiation. The Fuzhenghefuzhiyang (FZHFZY) formula created by Chuanjian Lu, a master of Chinese medicine in dermatology, has been external used in the Guangdong Provincial Hospital of Chinese Medicine for the treatment of psoriasis, but its mechanisms of action against psoriasis remain poorly understood. This study involved an exploration of the effects of FZHFZY on epidermal differentiation and its underlying mechanisms in interleukin (IL)-17A/IL-22/interferon (IFN)-γ/tumour necrosis factor (TNF)-α-stimulated HaCaT cells and in a mouse model of imiquimod (IMQ)-induced psoriasis.

Rationale: Sulfur mustard is a blister agent prohibited by the Chemical Weapons Convention, and the detection of its hydrolysis product, thiodiglycol (TDG), is an important indicator of blister agent contamination. Due to the poor volatility and low extraction efficiency of TDG, derivatization gas chromatography or liquid chromatography is required for conventional methods, and the detection process is cumbersome and time-consuming.

Methods: A microextraction by packed sorbent (MEPS) device and a nano-electrospray ionization (nano-ESI) device were used.
