Analysis of the mechanism by which calcium negatively regulates the tyrosine phosphorylation cascade associated with sperm capacitation [PDF]

, 2004
The capacitation of mammalian spermatozoa involves the activation of a cAMP-mediated signal transduction pathway that drives tyrosine phosphorylation via mechanisms that are unique to this cell type.

KCNJ4 variants disrupt inward‐rectifier potassium channel function and cause refractory epilepsy

Epilepsia, EarlyView.
Abstract Objective Epilepsy is a common neurological disorder with a strong genetic basis, most frequently arising from ion channel dysfunction. Although multiple inwardly rectifying potassium (Kir) channels have been implicated in epileptogenesis, the contribution of KCNJ4, which encodes the Kir2.3 channel, has not previously been established in human

Production of a new Plant-Based Milk from Adenanthera pavonina seed and evaluation of its nutritional and health Benefits [PDF]

, 2018
A new plant milk was discovered from the seed of Adenanthera pavonina. The physicochemical and nutritional properties of the new pro-milk extract were assessed, and their biochemical effects were compared with those of soy bean extracts.

Women with epilepsy: Evidence‐based counseling across the lifespan

Epilepsia, EarlyView.
Abstract Women with epilepsy (WWE) encounter distinct and evolving challenges across the lifespan that require clinical management extending beyond seizure control alone. Although awareness of sex‐specific aspects of epilepsy has increased, important gaps remain in their integration into routine care.

Estimating the Rotation Rate in the Vacuolar Proton-ATPase in Native Yeast Vacuolar Membranes [PDF]

, 2012
The rate of rotation of the rotor of the yeast vacuolar proton-ATPase (V-ATPase), relative to the stator or the steady parts of enzyme, is estimated in native vacuolar membrane vesicles of Saccharomyces cerevisiae under standardised conditions.

Tissue oxygenation dynamics during transition from seizure to spreading depolarization in rat brain

Epilepsia, EarlyView.
Abstract Objective Spreading depolarization (SD) is a phenomenon underlying various neurological conditions, including epilepsy. Researchers have suspected that local tissue oxygenation breakdown induces spontaneous SD. In this study, we investigated the relationship between spontaneous epileptic seizures and SD, with a focus on the role of local ...

Membrane transporter genes predict chemoradiotherapy response in patients with cervical cancer [PDF]

Einstein (São Paulo)
Introduction: Cervical cancer is the fourth most common cancer in women worldwide. Resistance to chemoradiotherapy in cervical cancer has been widely associated with membrane transport-related genes, particularly those encoding efflux transport proteins,

Analysis of the Movement of Chlamydomonas Flagella: The Function of the Radial-spoke System Is Revealed by Comparison of Wild-type and Mutant Flagella [PDF]

, 1982
The mutation uni-1 gives rise to uniflagellate Chlamydomonas cells which rotate around a fixed point in the microscope field, so that the flagellar bending pattern can be photographed easily .

Adenosine Triphosphatase Activity of Tritrichomonas foetus [PDF]

Journal of General Microbiology, 1979
Homogenates of Tritrichomonas foetus exhibited a Mg2+-dependent adenosine triphosphatase (ATPase) activity, with a pH optimum in Tris buffers of 8.2 to 8.3. The activity was not sensitive to oxygen. At high concentrations, quercetin and 4-chloro-7-nitrobenzofurazan inhibited ATPase activity in the cytoplasmic extract by 20 and 70%, respectively ...
