Photoplethysmography-Based Angiography of Skin Tumors in Arbitrary Areas of Human Body.

Noninvasive, rapid, and robust diagnostic techniques for clinical screening of tumors located in arbitrary areas of the human body are in demand. To address this challenge, we analyzed the feasibility of photoplethysmography-based angiography for assessing vascular structures within malignant and benign tumors. The proposed hardware and software were approved in a clinical study involving 30 patients with tumors located in the legs, torso, arms, and head.

Meta-analysis on the Efficacy of Platelet-rich Plasma in Patients with Androgenetic Alopecia.

Platelet-rich plasma (PRP) is an autologous platelet concentrate in plasma enriched with growth factors that may stimulate tissue regeneration, collagen formation, re-epithelization, and angiogenesis. PRP is widely used as an androgenetic alopecia treatment option. The present work aims to test the efficacy of various PRP methods, including those with single-spin and double-spin centrifugation.
