TerraSAR-X SAR data for classification of ice-free areas and glacier facies on Fildes Peninsula, King George Island, Antarctica.

The region of the Maritime Antarctic suffers significantly from climate change, resulting in regional warming and consequently affecting coverage. This study characterized three surface zones of Collins Glacier and three other zones in ice-free areas on the Fildes Peninsula, which has an area of 29.6 km².

Salt-affected soils in the Lopez de Bertodano Formation, polar semi-desert of Seymour Island, Antarctica: topographic or lithological controls?

Salinization is one of the main pedogenetic processes occurring on the semiarid zone of the Weddel sea, like in Seymour Island, where salt-affected soils are widespread. This study aimed to investigate whether topography controls the distribution of salt-affected soils on Seymour Island, particularly with reference to the Lopez de Bertodano Formation. Chemical and physical results from 45 soil profiles were used, where morphometric variables were extracted.

The Value of a Pet Scan in Selecting the Best Lymph Node to Biopsy, and Confirming the Diagnosis of Idiopathic Multicentric Castleman Disease with HLH And EBV Viremia in a Previously Healthy Adult.

Introduction: Castleman disease (CD) is a rare lymphoproliferative disorder having a variegated clinical presentation. Diagnosis of the idiopathic HIV- and HHV8-negative multicentric CD (iMCD) subtype poses a challenge given its non-specific clinical manifestations. iMCD presents as diffuse lymphadenopathy with inflammatory manifestations, primarily driven by interleukin-6 (IL-6).

Design of solid lipid nanoparticles for skin photoprotection through the topical delivery of caffeic acid-phthalimide.

Exposure of the skin to ultraviolet (UV) radiation is associated with many pathological conditions such as premature aging and skin cancer. Furthermore, members of Nicotinamide Adenine Dinucleotide Phosphate-oxidase (NADPH oxidase or NOX) enzyme family can produce UV-induced reactive oxygen species (ROS), even after cessation of radiation exposure. The caffeic acid-phthalimide (CF) compound is a potent antioxidant, which reduces the generation of ROS.
