Exposure of mouse and rat tumors of various types to more than 600 nm light 24 or 48 hours after an injection of hematoporphyrin resulted in a substantial number of long-term cures. Since hematoporphyrin is preferentially retained in tumor tissue, selective tumor destruction could be obtained. Light penetration studies and the high efficiency of this technique indicated its applicability even to certain deep-seated human tumors.

Rib fracture-related infection is a challenging complication of thoracic trauma due to the difficulty of treating it with antibiotics alone and the need for a second operation to remove the infected fixator and sterilize the surrounding infected tissue. In this study, inspired by the photocatalytic performance of and ion release from silver-based materials, including AgPO and AgS, a hybrid AgPO-AgS heterojunction was prepared based on anion exchange and a one-step calcination process to design a nonantibiotic coating aimed at preventing and treating rib fracture-related infection with short-term 808 nm near-infrared irradiation. Calcination at 250 °C enhanced the inductive effect of the phosphate radical and led to the formation of a tight nanoheterogeneous interface between AgPO and AgS, thereby promoting interfacial electron transfer and reducing the recombination of photogenerated carriers.

Layşmanyaz, yaklaşık 90'dan fazla ülke ve bölgeden bildirilen, ciddi ve endemik bir bulaşıcı hastalıktır. Kutanöz layşmanyaz (KL) ise vücudun açıkta kalan bölgelerinde oluşan, başlıca semptomları arasında vektör Phlebotomus ısırığından altı ay sonra kronikleşebilen veya kendiliğinden iyileşebilen ciltte tek, birden fazla ülserli veya nodüler lezyonlar bulunan, ölümcül olmayan ancak kalıcı izler bırakabilen bir hastalıktır. Klasik tedavi yöntemleri, uygulamada zorluk, direnç gelişimi ve yan etki gibi bir dizi soruna neden olmaktadır.

Atopic dermatitis (AD) is a chronic and inflammatory skin disorder characterized by impaired barrier function and imbalanced immunity. Recent advances have revealed that dysbiosis of skin microbiota plays important roles in the pathogenesis and development of AD. Meanwhile, endogenous and external factors contribute to the dysbiosis of skin microbiota in AD.

Cisplatin (CP) is a first-line platinum-based drug used for the treatment of head and neck cancer. However, tumor cells can diminish the therapeutic effects of CP through the detoxification system mediated by glutathione (GSH) and the nucleotide excision repair (NER) pathway. Herein, we present a light-activable and pH-responsive oxidative stress nanoamplifier (FPLC@IR OSNA), comprising an amphiphilic compound (FPLC) with Fmoc-lysine acting as a connector between a nitroimidazole derivative and a pH-responsive cinnamaldehyde (CA) derivative, loaded with photosensitizer IR780.
