In vitro regulation of collective cell migration: Understanding the role of physical and chemical microenvironments.

Collective cell migration is the primary mode of cellular movement during embryonic morphogenesis, tissue repair and regeneration, and cancer invasion. Distinct from single-cell migration, collective cell migration involves complex intercellular signaling cascades and force transmission. Consequently, cell collectives exhibit intricate and diverse migration patterns under the influence of the microenvironment in vivo.

Successful treatment of eyebrow intradermal nevi by shearing combined with electrocautery and curettage: Two case reports.

Background: An intradermal nevus is a common skin tumour, and the classical method of removal has a risk of recurrence and scarring. It is a challenge for dermatologists to treat eyebrow intradermal nevi quickly and efficiently. This study focused on investigating the efficacy and safety of shearing combined with electrocautery and curettage in the treatment of eyebrow intradermal nevi.

Biological Evaluation of the Antibacterial Retinoid CD437 in Cutibacterium acnes Infection.

Acne vulgaris is a complex skin disease involving infection by Cutibacterium acnes, inflammation, and hyperkeratinization. We evaluated the activity of the retinoid 6-[3-(adamantyl)-4-hydroxyphenyl]-2-naphthalene carboxylic acid (CD437) and 16 other retinoid analogs as potential anti- compounds and found that CD437 displayed the highest antimicrobial activity with an MIC against (ATCC 6919 and HM-513) of 1 μg/mL. CD437 demonstrated an MBC of 2 μg/mL compared to up to 64 μg/mL for the retinoid adapalene and up to 16 μg/mL for tetracycline, which are commonly used clinically to treat acne.

Successful surgical treatment of polybacterial gas gangrene confirmed by metagenomic next-generation sequencing detection: A case report.

Background: We report on a case of detected by metagenomics next-generation sequencing (mNGS) in a 53-year-old male patient with polymicrobial gas gangrene and successful treatment by surgery. This report raises awareness among dermatologists that when a patient is clinically suspected of a special type of pathogenic infection, the mNGS method should be preferred to identify the patient's pathogen infection as soon as possible and then take effective treatment in time to save patients' lives.

Case Summary: A 53-year-old male who worked in the aquatic market complained of redness and swelling of the lower limbs, blisters and ulcers with fever for 3 d.

(L.) Schrad (Bitter Apple Fruit): Promising Traditional Uses, Pharmacological Effects, Aspects, and Potential Applications.

Health consciousness and increased knowledge about the side effects of synthetic drugs have enhanced interest in traditional medicines. Medicinal plants offer cures for various diseases, leading to improved living standards. This has brought ethnomedicinal studies into the spotlight and increased demand for herb-based medicines.

A critical analysis of SARS-CoV-2 (COVID-19) complexities, emerging variants, and therapeutic interventions and vaccination strategies.

Coronavirus is a family of viruses that can cause diseases such as the common cold, severe acute respiratory syndrome (SARS), and Middle East respiratory syndrome (MERS). The universal outbreak of coronavirus disease 2019 (COVID-19) caused by SARS coronaviruses 2 (SARS-CoV-2) has become a global pandemic. The β-Coronaviruses, which caused SARS-CoV-2 (COVID-19), have spread in more than 213 countries, infected over 81 million people, and caused more than 1.

Injectable antimicrobial hydrogels with antimicrobial peptide and sanguinarine controlled release ability for preventing bacterial infections.

The emergence of antibiotic resistant bacteria represents a significant and common clinical problem worldwide as infections are becoming increasingly common. It is urgent to broaden the sources of biomaterials that can prevent both bacterial infection and antibiotic resistance. In this work, oxidized sodium alginate/aminated hyaluronic acid (OSA/AHA) hydrogel with various proportions was developed based on Schiff base reaction.

Resveratrol (RV): A pharmacological review and call for further research.

Resveratrol (RV) is a well-known polyphenolic compound in various plants, including grape, peanut, and berry fruits, which is quite famous for its association with several health benefits such as anti-obesity, cardioprotective neuroprotective, antitumor, antidiabetic, antioxidants, anti-age effects, and glucose metabolism. Significantly, promising therapeutic properties have been reported in various cancer, neurodegeneration, and atherosclerosis and are regulated by several synergistic pathways that control oxidative stress, cell death, and inflammation. Similarly, RV possesses a strong anti-adipogenic effect by inhibiting fat accumulation processes and activating oxidative and lipolytic pathways, exhibiting their cardioprotective effects by inhibiting platelet aggregation.

Curcumin ameliorates hypertension via gut-brain communication in spontaneously hypertensive rat.

Gut dysbiosis and dysregulation of gut-brain communication have been identified in hypertensive patients and animal models. Previous studies have shown that probiotic or prebiotic treatments exert positive effects on the pathophysiology of hypertension. This study aimed to examine the hypothesis that the microbiota-gut-brain axis is involved in the antihypertensive effects of curcumin, a potential prebiotic obtained from Curcuma longa.

High expression of disabled homolog 2-interacting protein contributes to tumor development and proliferation in cutaneous squamous cell carcinoma.

Background: Disabled homolog 2-interacting protein (DAB2IP), a Ras GTPase-activating protein, is downregulated in several cancers. Its depletion is involved in tumor cell proliferation, apoptosis, and metastasis, as well as epithelial-mesenchymal transition. The present study aimed to explore the potential role of DAB2IP in cutaneous squamous cell carcinoma (cSCC) and provide a theoretical basis for the diagnosis and targeted therapy of cSCC.

The clinical efficacy of treatment using the autologous non-cultured epidermal cell suspension technique for stable vitiligo in 41 patients.

Vitiligo is an acquired depigmentation skin disorder mainly caused by the destruction of melanocytes. There are many therapeutic options available for vitiligo, but the options are not uniformly effective. This study aimed to explore the clinical effect of the autologous non-cultured epidermal cell suspension (NCES) technique in the treatment of patients with stable vitiligo.

Identification and functional characterization of a novel transglutaminase 1 gene mutation associated with autosomal recessive congenital ichthyosis.

Background: Autosomal recessive congenital ichthyosis (ARCI) is a group of genetically heterogeneous diseases. Mutations in transglutaminase (TGase) 1 gene (TGM1, OMIM 190195) have been implicated in ARCI. However, little is known about TGM1 mutations in the Chinese population, and no functional studies have investigated the biological effect of mutant TGM1 on human epidermal keratinocytes (HaCaT) cells.

Ultrastructural study of symmetrical acral keratoderma.

Background: Symmetrical acral keratoderma is characterized by symmetrical brown hyperkeratotic patches on the acral extremities. However, no studies about its electron microscopic examination have been documented.

Objective: Our study was performed to further characterize the histopathology of symmetrical acral keratoderma.

Netherton syndrome in one Chinese adult with a novel mutation in the SPINK5 gene and immunohistochemical studies of LEKTI.

Background: Netherton syndrome (NS) is a severe autosomal recessive ichthyosis. It is characterized by congenital ichthyosiform erythroderma, trichorrhexis invaginata, ichthyosis linearis circumflexa, atopic diathesis, and frequent bacterial infections. The disease is caused by mutations in the SPINK5 (serine protease inhibitor Kazal-type 5) gene, a new type of serine protease inhibitor involved in the regulation of skin barrier formation and immunity.
