The purpose of this research was to evaluate the effect of penetration enhancers on permeation kinetics of nitrendipine (NTP) through two different skin models. The permeation profile and related kinetics parameters such as activity parameter, diffusion parameter, lag time, relative activity parameter and relative diffusion parameter of NTP was determined in presence of some novel and widely accepted permeation enhancers. Among all the more pronounced enhancing effect was obtained with oleic acid (OA) as it presented the highest permeability coefficient. The enhancement was found to be increased in the following order: Dimethyl sulphoxide (DMSO)

The investigation of changes in the membrane of cancer cells holds great potential for biomedical applications. Malignant cells exhibit overexpression of receptors, which can be used for targeted drug delivery, therapy, and bioimaging. Targeted bioimaging is one the most accurate imaging methods with a non-invasive nature, allowing for localization of the malignant cell without disrupting cellular integrity.

Gene therapy targeting ischemic heart disease is a promising therapeutic avenue, but it is mostly restricted to viral-based delivery approaches which are limited due to off-target immunological responses. Focused ultrasound presents a non-viral, image-guided technique in which circulating intravascular microbubble contrast agents can reversibly enhance vascular permeability and gene penetration. Here, we explore the influence of flow rate on the microbubble-assisted delivery of miR-126, a potent pro-angiogenic biologic, using a custom acoustically coupled pressurized mesenteric artery model.

Alzheimer's disease (AD) is gradually increasing in prevalence and the complexity of its pathogenesis has led to a lengthy process of developing therapeutic drugs with limited success. Faced with this challenge, we proposed using a state-of-the-art drug screening algorithm to identify potential therapeutic compounds for AD from traditional Chinese medicine formulas with strong empirical support. We developed four deep neural network (DNN) models for AD drugs screening at the disease and target levels.

Purpose: Basal Cell Carcinoma (BCC), the most common subtype of non-melanoma skin cancers (NMSC), is prevalent worldwide and poses significant challenges due to their increasing incidence and complex treatment considerations. Existing clinical approaches, such as Mohs micrographic surgery, are time-consuming and labour-intensive, requiring meticulous layer-by-layer excision and examination, which can significantly extend the duration of the procedure. Current optical imaging solutions also lack the necessary spatial resolution, penetration depth, and contrast for effective clinical use.

Psoriasis is a chronic and incurable inflammatory skin disease usually requiring long-term disease management. Natural phytochemical resveratrol (RES) has been known for high efficiency and low toxicity, exhibiting good anti-psoriasis potential. However, its biological activity is limited by poor solubility, chemical instability, and insufficient skin retention.
