Psoriasis is a common chronic skin inflammatory disease characterized by an exaggerated proliferation of keratinocytes. B-cell receptor-associated protein 31 (BCAP 31) plays critical roles in induction of proliferation and apoptosis. The current study aimed at evaluation of the immunohistochemical localization of BCAP 31 in psoriatic skin compared to normal skin in addition of correlating BCAP31 expression with the clinical and pathological parameters of psoriasis. The present study was carried out on skin biopsies from 30 psoriatic patients and 10 normal skin (control group). BCAP31 was not expressed in normal skin either epidermis or dermis, while it was expressed in epidermis of 15 psoriatic cases and in dermis of 13 cases with a significant difference between the two groups ( < .05). Strong epidermal BCAP 31 expression was associated with marked parakeratosis ( = .025). There was a significant co-parallel epidermal and dermal expression of BCAP31 in psoriasis ( < .05). The role of BCAP 31 is not only confined to its expression by affected keratinocytes but extended to its localization to dermal lymphocytes where they were correlated with each other. The up- regulation of BCAP 31 in psoriatic lesion compared to normal skin may suggest its use as a target therapy for treatment of psoriasis that necessitates further studies to clarify.

Traditional wound care preparations frequently face challenges such as complex care protocols, poor patient compliance, limited skin permeability, lack of aesthetics, and inconvenience, in addition to the risk of bacterial infection. We developed a spray film preparation containing nanocellulose and L-serine modified nanosilver, capable of rapidly forming a transparent film on the skin within minutes of application. The incorporation of nanocellulose imparted protective, moisturizing, and breathable properties to the film, allowing for easy removal after use.

Background: Cutaneous squamous cell carcinoma (cSCC) is an aggressive tumor with unclear margins. Photodynamic diagnosis (PDD) enables the differentiation of tumor tissue from normal tissue via visible fluorescence. Photodynamic therapy (PDT) is widely used in the treatment of non-melanoma skin tumors.

Introduction And Importance: Calcific tendinitis occurring in the popliteal tendon is extremely rare and has rarely been reported in the past. This case describes a patient who underwent arthroscopic surgery to remove the calcification of the popliteal tendon and achieved satisfactory results after surgery, providing valuable evidence for the feasibility of arthroscopic treatment of calcific tendinitis of the popliteal tendon.
Case Presentation: The patient was a 55-year-old female who was admitted to the hospital due to right knee pain and limited mobility.

Membranes that destroy anticancer peptides can bind to negatively charged cancer cell membranes through electrostatic interactions, destroying their functions and leading to cancer cell necrosis. Temporin-1CEa, obtained from the skin secretions of the Chinese frog Rana chensinensis, is an anticancer peptide with 17 amino acid residues that exhibits concentration-dependent cytotoxicity against a variety of cancer cell lines, although it has no obvious cytotoxicity to normal HUVECs. In this work, we designed and synthesized 12 derivative peptides through double-cysteine scanning of temporin-1CEa-truncated peptides.

Article Synopsis
- E-commerce struggles with issues like content sameness and user anxiety about making purchases, prompting a study on perceived risk based on online reviews.
- The study used a dataset of over 262,000 reviews and a predictive model that effectively identified 11 key factors impacting perceived risk, achieving high accuracy metrics (precision of 84%, recall of 86%, F1 score of 85%).
- Key features influencing perceived risk vary by product type; for electronics, quality, functionality, and price are crucial, while for skincare, skin safety is the top concern, highlighting differences in risk perception.
