Single GAF domain phytochrome exhibits a pH-dependent shunt on the millisecond timescale.

The light-sensing activity of phytochromes is based on the reversible light-induced switching between two isomerization states of the bilin chromophore. These photo-transformations may not necessarily be only unidirectional, but could potentially branch back to the initial ground state in a thermally driven process termed shunt. Such shunts have been rarely reported, and thus our understanding of this process and its governing factors are limited.

Non-Resonant Magnetic X-ray Scattering as a Probe of Ultrafast Molecular Spin-State Dynamics: An Ab Initio Theory.

With the advancement of high harmonic generation and X-ray free-electron lasers (XFELs) to the attosecond domain, the studies of the ultrafast electron and spin dynamics became possible. Yet, the methods for efficient control and measurement of the quantum state are to be further developed. In this publication, we propose using magnetic X-ray scattering (MXS) for resolving the molecular spin-state dynamics and establish a complete protocol to simulate MXS diffraction patterns in molecules with ab initio quantum chemistry based on the multiconfigurational method.

X-ray absorption spectroscopy of FeH to aid its identification in astrochemical environments.

Promoting Classroom Climate and Why it Matters in Anti-Hate Speech Prevention Programs: A HateLess Evaluation Study.

Inclusive and supportive classroom environments are essential, particularly during political and societal crises such as wars, disinformation, polarization, and rising populism and extremism. While existing research underscores the importance of such environments, few studies comprehensively examine the impact of anti-hate speech prevention programs on classroom dynamics and students' social development. This study addressed this gap by investigating the direct and indirect effects of the HateLess anti-hate speech prevention program on inclusive classroom climate, classroom cohesion, empathy, and self-efficacy among adolescents.

Linear ubiquitination at damaged lysosomes induces local NFKB activation and controls cell survival.

Lysosomes are the major cellular organelles responsible for nutrient recycling and degradation of cellular material. Maintenance of lysosomal integrity is essential for cellular homeostasis and lysosomal membrane permeabilization (LMP) sensitizes toward cell death. Damaged lysosomes are repaired or degraded via lysophagy, during which glycans, exposed on ruptured lysosomal membranes, are recognized by galectins leading to K48- and K63-linked poly-ubiquitination (poly-Ub) of lysosomal proteins followed by recruitment of the macroautophagic/autophagic machinery and degradation.

Conversely, cellular-based responses play a vital role in MM patients. However, the extent and duration of cellular-induced protection remain unclear to date.

Rapid and reproducible generation of glioblastoma spheroids for high-throughput drug screening.

Identifying new substances that could potentially be used for tumor therapy and the precise analysis of their spectrum of action requires models that are as similar as possible to the tumor present in the patient. Traditionally, two-dimensional (2D) cell cultures are used. However, these only resemble solid tumors to a limited extent.

Impact of ALDH1A1 Expression in Intrahepatic Cholangiocellular Carcinoma.

Intrahepatic cholangiocarcinoma (iCC) is a rare malignant liver tumor with limited therapeutic advancements. Despite its increasing global incidence knowledge of treatment options remains stagnant, leading to poor five-year patient survival rates and high recurrence post-surgery. ALDH1A1, a member of the ALDH superfamily, is associated with cancer stem cells and has conflicting reports regarding its prognostic role in iCC.

The Neuroprotective Effects of Caffeine in a Neonatal Hypoxia-Ischemia Model are Regulated through the AMPK/mTOR Pathway.

Neonatal hypoxic-ischemic encephalopathy (HIE) is the most common cause of death and long-term disabilities in term neonates. Caffeine exerts anti-inflammatory effects and has been used in neonatal intensive care units in recent decades. In our neonatal rat model of hypoxic-ischemic (HI) brain injury, we demonstrated that a single daily dose of caffeine (40 mg/kg) for 3 days post-HI reduced brain tissue loss and microgliosis compared to the vehicle group.
