Advances in cancer immunotherapy have offered new hope for patients with metastatic disease. This unfolding success story has been exemplified by a growing arsenal of novel immunotherapeutics, including blocking antibodies targeting immune checkpoint pathways, cancer vaccines, and adoptive cell therapy (ACT). Nonetheless, clinical benefit remains highly variable and patient-specific, in part, because all immunotherapeutic regimens vitally hinge on the capacity of endogenous and/or adoptively transferred T-effector (Teff) cells, including chimeric antigen receptor (CAR) T cells, to home efficiently into tumor target tissue...

Chronic wounds, especially in diabetic patients, represent a challenging health issue. Since standard treatment protocols often do not provide satisfactory results, additional treatment methods-like phototherapy using low-level light therapy-are being investigated. The aim of our study was to evaluate the effect of phototherapy with light-emitting diodes on chronic wound treatment in diabetic and non-diabetic patients. Since a sufficient blood supply is mandatory for wound healing, the evaluation of microcirculation in the healthy skin at a wound's edge was the main outcome measure...

BACKGROUND: Testicular torsion is a common problem and, to date, there is no agent to preserve testicular function following detorsion. Platelet-rich plasma (PRP), with its rich growth factor composition, has proven beneficial in regenerative therapy. It is believed that PRP has not been studied in testis for ischemia/reperfusion (I/R) injury. OBJECTIVE: This study investigated the effect of PRP in an I/R rat model 1 month after detorsion. STUDY DESIGN: Of 24 adult male Sprague-Dawley rats, 18 were randomly assigned into three groups, with six in each: control, I/R and I/R + PRP...

Low-intensity extracorporeal shock wave therapy (Li-ESWT) is used in the treatment of erectile dysfunction, but its mechanisms are not well understood. Previously, we found that Li-ESWT increased the expression of brain-derived neurotrophic factor (BDNF). Here we assessed the underlying signaling pathways in Schwann cells in vitro and in penis tissue in vivo after nerve injury. The result indicated that BDNF were significantly increased by the Li-ESWT after nerve injury, as well as the expression of BDNF in Schwann cells (SCs, RT4-D6P2T) in vitro...

Barrett's esophagus (BE) is generally accepted as the only precursor to esophageal adenocarcinoma (EAC). Deoxycholic acid (DCA)-induced inflammation and apoptotic resistance play an important role in the carcinogenesis and progression from BE to EAC. Diallyl disulfide (DADS) is a garlic-derived natural organosulfur compound. This study investigated whether DADS has chemopreventive effects against BE and the potentially related signaling pathway. BAR-T cells were treated with DCA in the presence or absence of DADS...

REVIEW
Keiji Inoue
Photodynamic therapy using 5-aminolevulinic acid is a treatment method in which the fluorescent substance of protoporphyrin IX excessively accumulated specifically in cancer cells is excited by visible red or green light irradiation, and reactive oxygen is produced and injures cancer cells. Photodynamic therapy using 5-aminolevulinic acid less markedly influences the surrounding normal cells and tissue as a result of no accumulation of protoporphyrin IX, being a low-invasive, less harmful treatment localized to cancer...

Use of photostimulation including low-level light emitting diode (LED) therapy has broadened greatly in recent years because it is compact, portable, and easy to use. Here, the effects of photostimulation by LED (610 nm) therapy on ischemic brain damage was investigated in mice in which treatment started after a stroke in a clinically relevant setting. The mice underwent LED therapy (20 min) twice a day for 3 days, commencing at 4 hours post-ischemia. LED therapy group generated a significantly smaller infarct size and improvements in neurological function based on neurologic test score...

Human immunodeficiency virus (HIV-1) infection remains a major health problem despite the use of highly active antiretroviral therapy (HAART), which has greatly reduced mortality rates. Due to the unavailability of an effective vaccine and treatment that would completely eradicate the virus in infected individuals, the quest for new therapies continues. Low level laser therapy (LLLT) involves the exposure of cells to low levels of red or infrared light. LLLT has been widely used in different medical conditions, but not in HIV-1 infection...

Deaths related with human immunodeficiency virus (HIV) infections have been decreased by the introduction of combined anti-retroviral therapy (ART) into the clinical practice. Combined ART usually consists of two nucleoside/nucleotide analogs reverse transcriptase inhibitors (NRTI) that is called backbone and a third drug that belongs to either non-nucleoside/nucleotide reverse transcriptase inhibitors (NNRTI), protease inhibitors (PI), integrase strand transfer inhibitors (INSTI) or entry inhibitors. During abacavir therapy which is a member of NRTI, hypersensitivity reactions can occur approximately 4-9% of the patients that lead difficulties for the management of HIV infections...

BACKGROUND AND OBJECTIVE: Various irradiances have been reported to be beneficial for the treatment of neuropathic pain with near infrared light. However, the mechanistic basis for the beneficial outcomes may vary based on the level of irradiance or fluence rate used. Using in vivo and in vitro experimental models, this study determined the mechanistic basis of photobiomodulation therapy (PBMT) for the treatment of neuropathic pain using a high irradiance. STUDY DESIGN/MATERIALS AND METHODS: In vitro experiments: Cultured, rat DRG were randomly assigned to control or laser treatment (LT) groups with different irradiation times (2, 5, 30, 60, or 120 seconds)...
