Die Phototherapie nutzt die photobiologische Wirkung von ultravioletter (UV-)Strahlung auf unseren Organismus. Die verschiedenen Wellenlängen der Strahlung rufen dabei ganz unterschiedliche Effekte hervor. Der gezielte Einsatz von UV-A und UV-B, gegebenenfalls auch in Kombination mit dem Photosensibilisator Psoralen im Rahmen einer PUVA-Therapie, ermöglicht dem Dermatologen die effektive Behandlung der verschiedensten Hautkrankheiten. Das Indikationsspektrum der Phototherapie reicht von oberflächlichen Ekzemerkrankungen, Psoriasis, malignen Erkrankungen wie dem kutanen T-Zell-Lymphom, bis hin zu tief in der Dermis lokalisierten sklerosierenden Erkrankungen wie der Sklerodermie. Das Verständnis der zugrunde liegenden photobiologischen Wirkmechanismen der verschiedenen Bereiche der UV-Strahlung und die sich daraus ableitenden Indikationen für eine Phototherapie soll der folgende Artikel ermöglichen.

Alcohol consumption is an important risk factor for multiple diseases. It is typically assessed via self-report, which is open to measurement error through recall bias. Instead, molecular data such as blood-based DNA methylation (DNAm) could be used to derive a more objective measure of alcohol consumption by incorporating information from cytosine-phosphate-guanine (CpG) sites known to be linked to the trait.

Metabolic flexibility is key for the function of myeloid cells. Arginine metabolism is integral to the regulation of myeloid cell responses. Nitric oxide (NO) production from arginine is vital for the antimicrobial and pro-inflammatory responses.

Background: Arginine infusion stimulates copeptin secretion, a surrogate marker of arginine vasopressin (AVP), thereby serving as a diagnostic test in the differential diagnosis of suspected AVP deficiency (AVP-D). Yet, the precise mechanism underlying the stimulatory effect of arginine on the vasopressinergic system remains elusive. Arginine plays a significant role in the urea cycle and increases the production of urea.

Purpose: Sarcopenia, characterized by loss of skeletal muscle mass (SMM) and strength, often leads to dysphagia in the elderly. This condition can also worsen treatment outcomes in head and neck cancer (HNC) patients, who are susceptible to swallowing difficulties. This study aimed to establish the correlation between swallowing muscle mass (SwMM) and SMM in HNC patients.

Group cooperation is a cornerstone of human society, enabling achievements that surpass individual capabilities. However, groups also define and restrict who benefits from cooperative actions and who does not, raising the question of how to foster cooperation across group boundaries. This study investigates the impact of voluntary mobility across group boundaries on intergroup cooperation.
