Skin acts as a dynamic interface with the environment. Pathological alterations in the skin barrier are associated with skin diseases. These conditions are characterized by specific impairments in epidermal barrier functions. Despite its protective nature, the skin can be a relevant route of drug administration, both for topical and transdermal therapy, allowing for improved drug delivery and reducing the incidence of adverse reactions. This manuscript reviews transcutaneous drug delivery as a strategy for treating localized and systemic conditions, highlighting the importance of skin models in the evaluation of drug efficacy and barrier function. It explores advances in in vitro, ex vivo, in vivo, and in silico models for studying cellular uptake, wound healing, oxidative stress, anti-inflammatory, and immune modulation activities. Disease-specific skin models are also discussed.

Hepatocellular carcinoma (HCC) is one of the most lethal malignancies worldwide, characterized by its complex pathogenesis and poor therapeutic outcomes. Despite recent advances in targeted molecular therapies, immune checkpoint inhibitors (ICIs), radiotherapy, and conventional chemotherapy, the five-year survival rate for this neoplasm remains dismally low. The progress in nanotechnology has revolutionized cancer treatment in recent years.

Cancer remains a critical global health challenge, necessitating advanced drug delivery systems through innovations in materials science and nanotechnology. This study evaluates Gadolinium Metal-Organic Frameworks (Gd-MOFs) as potential drug delivery systems for anticancer therapy, particularly when combined with radiotherapy. Gd-MOFs were synthesized using terephthalic acid and gadolinium (III) chloride hexahydrate, then loaded with methotrexate (MTX).

Background: Many patients with ulcerative colitis report ongoing diarrhoea even when their disease is stable and in remission.
Design: MODULATE was a pragmatic, multicentre, seamless, adaptive, phase 2/3 open-label, parallel-group, multiarm multistage randomised controlled trial.
Setting And Participants: People aged over 18 years with stable ulcerative colitis who had diarrhoea, recruited from secondary care sites in the United Kingdom.

Introduction: Diabetic foot ulcers (DFUs) are a severe complication of diabetes, often leading to amputation. Hyperglycemia induced nerve and vascular damage significantly increases DFU risk. The advent of 3D printing technology presents a revolutionary concurrently address glycemic control and wound management, potentially improving patient adherence and offering a more holistic treatment strategy.

Platinum-based chemotherapy, despite being a cornerstone of cancer treatment, faces significant challenges due to acquired drug resistance. To address this issue, we have designed three organelle-targeting platinum(IV) prodrugs conjugated with BODIPY fluorophores, enabling spatiotemporal control through green light irradiation. These BODIPY-Pt(IV) conjugates exhibit excellent stability in PBS buffer, demonstrating resilience under physiological conditions.
