Role of Pkc Delta in Uv Radiation Dna Damage Repair
, 2016 DNA damage caused by ultraviolet radiation (UV), such as cyclobutane pyrimidine dimers (CPD), is repaired by the nucleotide excision repair (NER) pathway. When NER is defective, DNA damage is not repaired, leading to mutations and skin cancer.

The inner annular gap for pulsar radiation: gamma-ray and radio emission
, 2004 The inner annular gap (IAG), a new type of inner gap whose magnetic field lines intersect the null charge surface (NCS), is proposed to explain gamma-ray and radio emission from pulsars. The IAG can be an important source for high-energy particles.

MHD simulations of coronal heating
, 2015 The problem of heating the solar corona requires the conversion of magnetic energy into thermal energy. Presently, there are two promising mechanisms for heating the solar corona: wave heating and nanoflare heating.

Charakterisierung und Signalanalyse von TRD-Prototypen für das CBM Experiment
, 2013 Als es in den 1920er und 1930er Jahren zur Entdeckung des expandierenden Raums, gemessen über die kosmologische Rotverschiebung, kommt, wird daraus erstmals die Idee eines kleinsten Ursprungspunkts zu Beginn der Zeit postuliert.

Senolytic Therapy as a Preventive Strategy for Spine Degeneration and Pain
Advanced Science, EarlyView.Cellular senescence promotes inflammation, tissue degeneration, and chronic back pain. In sparc‐null mice, early oral administration of the senolytic agents o‐vanillin and RG‐7112 reduced senescent cell burden and pro‐inflammatory SASP signaling across intervertebral discs, endplates, vertebral bone, and spinal cord.

Advanced Science, EarlyView.Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

Advanced Science, EarlyView.A reservoir‐guided silver‐nanoparticle soldering strategy is developed for bending‐resistant 3D graphene–metal heterojunctions. Controlled hot‐plate evaporation confines conductive ink within the metal reservoir, suppressing spreading and protecting the LIG interface from deformation‐induced fracture.
