Effects of extracellular Ca++, K+, and Na+ on cone and retinal pigment epithelium retinomotor movements in isolated teleost retinas. [PDF]

, 1984
We have examined the effects of changes in extracellular ionic composition on cone and retinal pigment epithelium (RPE) retinomotor movements in cultured isolated teleost retinas.

Unraveling the Morphological and Functional Maturation Mechanisms Underlying Human Neural Development Using iPSCs‐Derived Neuronal Model

Advanced Science, EarlyView.
Using human induced pluripotent stem cells (hiPSCs)‐derived neuronal model, Tian and colleagues reveal that voltage‐gated calcium channels Cav1.2 and Cav1.3, and their mediated calcium ion influx, are essential for early morphogenesis of human neuronal development, while ECEL1 underlies human neuronal functional developmental maturation through CALM3 ...

Dual Targeting of Tau Kinases and Autophagy by Abemaciclib Independent of CDK4/6 Inhibition

Advanced Science, EarlyView.
Abemaciclib rescues cognitive function and attenuates tau pathology in Alzheimer's disease models, but not through its known cancer‐fighting mechanism. This study demonstrates that abemaciclib operates independently of CDK4/6 inhibition, instead directly targeting tau kinases CaMKII and GSK3β while simultaneously promoting autophagic clearance of ...

ERM Inhibition Confers Ferroptosis Resistance through ROS‐Induced NRF2 Signaling

Advanced Science, EarlyView.
ERM inhibition disrupts ERM‐actin interactions, elevating ROS and triggering KEAP1 degradation, which stabilizes and activates NRF2. Nuclear NRF2 induces cytoprotective genes, notably HMOX1, enhancing redox buffering and suppressing lipid peroxidation to resist erastin‐induced ferroptosis.

NADH‐Reductive Stress Induced by Dihydrolipoamide Dehydrogenase Activation Contributes to Cuproptosis

Advanced Science, EarlyView.
This study demonstrates a cuproptosis mechanism involving nicotinamide adenine dinucleotide (NADH)‐reductive stress in neural cells. Copper activates dihydrolipoamide dehydrogenase under mitochondrial pH, accumulating NADH. Copper also induces mitochondrial permeability transition pore opening, facilitating NADH translocation to the cytosol and ...

Desempenho de bezerras de corte em pastagem de azevém recebendo farelo de arroz com ou sem monensina

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
RESUMO Foi estudado o desempenho de bezerras de corte em pastagem de azevém (Lolium multiflorum Lam.), com animais exclusivamente em pastejo ou recebendo farelo de arroz integral (FAI) em nível de 0,8% do peso corporal, associado ou não à monensina.

Glucocorticoid-regulated localization of cell surface glycoproteins in rat hepatoma cells is mediated within the Golgi complex. [PDF]

, 1988
Glucocorticoid hormones regulate the post-translational maturation and sorting of cell surface and extracellular mouse mammary tumor virus (MMTV) glycoproteins in M1.54 cells, a stably infected rat hepatoma cell line.

Synthesis, Characterization, Biological Properties, and Sensor Applications of Novel Thiosemicarbazone Derivatives

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT In this study, novel thiosemicarbazone derivative molecules (5a–j) were synthesized. The characterization of the synthesized molecules was carried out using 1H–, 13C–NMR, FT–IR, and Q–TOF spectroscopic techniques. Then, the inhibitory effect of these compounds was examined for human carbonic anhydrase I and II (hCA I, and II) and ...
