Bcat2-Mediated Branched-Chain Amino Acid Catabolism Is Linked to the Aggravated Inflammation in Obese with Psoriasis Mice.

Scope: The global prevalence of obesity has significantly increased, presenting a major health challenge. High-fat diet (HFD)-induced obesity is closely related to the disease severity of psoriasis, but the mechanism is not fully understood.

Methods And Results: The study utilizes the HFD-induced obesity model along with an imiquimod (IMQ)-induced psoriasis-like mouse model (HFD-IMQ) to conduct transcriptomics and metabolomic analyses.

Pruritus Anesis in Dystrophic Epidermolysis Bullosa Pruriginosa with Dupilumab.

Dystrophic epidermolysis bullosa pruriginosa (DEB-Pr) is a rare subtype of dystrophic epidermolysis bullosa, and traditional treatments have limited efficacy. Dupilumab has demonstrated remarkable efficacy in relieving pruritus. In this case study, after traditional treatment failed, providers recommended the patient begin dupilumab to treat his pruritus.

Jianpi-Yangxue-Jiedu decoction improves the energy metabolism of psoriasis mice by regulating the electron transfer of oxidative phosphorylation.

Ethnopharmacological Relevance: The inflammatory skin condition psoriasis is immune-related. The decoction of Jianpi-Yangxue-Jiiedu (JPYX) is a useful medication for psoriasis. However, the underlying mechanics of JPYX have not yet been clarified.

Lipopolysaccharide induces skin scarring through the TLR4/Myd88 inflammatory signaling pathway in dermal fibroblasts.

Skin scarring is a frequent complication of the wound healing process. Bacterial contamination and prolonged inflammation in wounds are thought to play significant roles during scar formation, but little is known about their specific mechanisms of action. In this study, hypertrophic scar derived fibroblasts (HSFs) and paired normal skin derived fibroblasts (NSFs) were used to evaluate the effects of lipopolysaccharide (LPS) on inflammation-induced skin scarring and explore the inflammation-mediated mechanism of activity of LPS on dermal fibroblasts.

[Optimal processing technology of Zhangbang vinegar-processed Olibanum with multi-indicator-response surface methodology and anticoagulant effect evaluation].

This study first optimized the processing technology for Zhangbang vinegar-processed Olibanum and investigated its in vitro anticoagulant activity. A multi-index-response surface methodology was used, with yield, powder yield, and the relative percentage of the content of six non-volatile components [11-keto-boswellic acid(KBA), 3-acetyl-11-keto-boswellic acid(AKBA), β-elemonic acid, α-boswellic acid(α-BA), β-boswellic acid(β-BA), and α-acetyl-boswellic acid(α-BA)] and three volatile components(octyl acetate, incensole, and incensole acetate) as evaluation indicators. Analytical hierarchy process(AHP) combined with coefficient of variation method was used to calculate the weight of each indicator and calculate the comprehensive score(OD).

CircFAT1 Promotes the Proliferation and Invasion of Malignant Melanoma through miR375-SLC7A11 Signal Axis.

Background: Circular RNA, as a member of noncoding RNA, plays an important role in the occurrence, development and metastasis of tumor cells. So far, the correlation between circular RNA and malignant melanoma remains obscure.

Methods: RNA expression of circFAT1 and miR-375 in malignant melanoma (MM) tissues and cell lines was detected by RT-PCR.

CD44 targeted indirubin nanocrystal-loaded hyaluronic acid hydrogel for the treatment of psoriasis.

Despite advances in transdermal drug delivery for treating psoriasis, there are still unmet medical needs, hyaluronic acid (HA)-based topical formulations as nanocarriers, which can increase drug concentration in psoriatic skin through CD44-assisted targeting. Here, HA was utilized as a matrix for nanocrystal-based hydrogel (NC-gel) to deliver indirubin topically for psoriasis treatments. Indirubin nanocrystals (NCs) were prepared through wet media milling and were then mixed with HA to create indirubin NC/HA gels.

Analysis of the mechanism underlying diabetic wound healing acceleration by Calycosin-7-glycoside using network pharmacology and molecular docking.

Background: Diabetic wounds represent a severe clinical challenge in which impaired M2 macrophage polarization and continuous macrophage glycolysis play crucial roles. Calycosin-7-glucoside (CG) is an isoflavone component in Astragali Radix (AR), which has become a research focus for treating diabetic wounds following reports indicating that it has anti-inflammatory effects. However, the mechanism through which CG can treat diabetic wounds is yet to be deciphered.

[Mechanism of Euodiae Fructus stir-fried with water decoction of Coptidis Rhizoma in treatment of chronic colitis based on UPLC-Q-TOF-MS, network pharmacology and experimental verification].

To elucidate the mechanism of Euodiae Fructus stir-fried with water decoction of Coptidis Rhizoma in the treatment of chronic colitis, this study employed ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS), network pharmacology, and experimental verification to predict the involved targets and signaling pathways. The chronic colitis mouse model was constructed to verify the core targets. A total of 48 compounds in the herbal medicine were identified by UPLC-Q-TOF-MS.

Individualized tourism recommendation based on self-attention.

Although the era of big data has brought convenience to daily life, it has also caused many problems. In the field of scenic tourism, it is increasingly difficult for people to choose the scenic spot that meets their needs from mass information. To provide high-quality services to users, a recommended tourism model is introduced in this paper.

Efficacy and safety of dupilumab in pediatric patients with moderate to severe atopic dermatitis: a real-world study.

Dupilumab is the first human monoclonal antibody that treats atopic dermatitis (AD) by blocking interleukin 4 (IL-4) and interleukin 13 (IL-13), which can suppress the Th2 inflammatory reaction. Effective treatments for pediatric AD patients are limited; therefore, we aimed to assess the efficacy and safety of dupilumab in pediatric AD patients. Fifteen pediatric patients diagnosed with moderate to severe AD and treated with dupilumab were enrolled in this study.

A DFT study on the structure activity relationship of the natural xanthotoxin-based pharmaceutical cocrystals.

In this work, the pharmaceutical cocrystals xanthotoxin-para-aminobenzoic acid (XT-PABA) and xanthotoxin-oxalic acid (XT-OA) were systematically investigated in the gas and water phases by using the quantum chemical approach. The weak intermolecular interactions have been estimated and the O1…H4 (O1…H5) intermolecular hydrogen bond (IHB) with moderate intensity and partial covalent natures was confirmed based on the computed structural parameters, topology analysis, and reduced density gradient (RDG) isosurfaces. The electrophilic and nucleophilic reactivities of different positions associated with intermolecular interactions in XT, PABA, and OA were predicted by plotting the molecular electrostatic potential (MESP) diagrams.
