Dual role of spreading depolarization in an epileptic focus

open access: yesEpilepsia, EarlyView.
Abstract Objective Spreading depolarizations (SDs) are often associated with epileptic discharges. Although SDs are traditionally thought to contribute to postictal depression and termination of epileptic discharges, seizures may also occur during SDs or may even follow SDs, suggesting that interactions between SD and seizures are more complex.

Genetic variability of Indian yaks using random amplified polymorphic DNA markers

open access: yes, 2013
Indian yaks are categorized into common yaks, bisonian yaks and bareback yaks. Genetic similarities and divergence among them was analyzed by random amplified polymorphic DNA (RAPD) technique using ten decamer oligonuclotide primers.

Pyruvate dehydrogenase autoantibodies in autoantibody‐negative patients with seizures are associated with reduced pyruvate dehydrogenase activity

open access: yesEpilepsia, EarlyView.
Abstract Objective We investigated the presence and potential functional relevance of antimitochondrial autoantibodies in patients suspicious for autoimmune encephalitis (AIE) associated with psychiatric symptoms and/or seizures, who were negative for known antineuronal autoantibodies.

Ultrafast oscillations in the human brain and their functional significance

open access: yesEpilepsia, EarlyView.
Abstract Objective The upper frequency limit of human brain activity remains unknown. Using ultrahigh sampling rate (≥20 kHz) intracranial microelectroencephalography, this study aimed to systematically explore and quantitatively characterize brain field oscillations beyond the established high‐frequency oscillation range (>2 kHz), and to determine ...

Effects of Trace Elements and Vitamins on the Synthesis of Steroid Hormones in Follicular Granulosa Cells of Yak

open access: yesVeterinary Sciences
Yak (Bos grunniens), a special breed of cattle on the Qinghai–Tibet Plateau, has low fertility due to nutritional deficiency, especially the trace elements. The steroid hormones estradiol (E2) and progesterone (P4) synthesized by yak follicular granulosa

Environmental Control for Edible Fungi Cultivation Based on Temporal Information and Deep Learning

open access: yesFood Bioengineering, EarlyView.
ABSTRACT Currently, there are still prevalent issues in greenhouse environmental regulation, such as response lag, low control accuracy, and difficulty in coping with sudden environmental disturbances. To achieve high‐precision and dynamic control of the edible fungi cultivation environment, this study proposes an edible fungi environmental control ...

Chiral perovskites for next‐generation chiral optoelectronics and spintronics

open access: yesFlexMat, EarlyView.
Benefiting from structural inversion symmetry breaking and strong spin‐orbit coupling, chiral perovskites possess intriguing chiral optical and spin properties. We overview their advances and core applications in perovskite solar cells, circularly polarized light detectors and spin circularly polarized‐light‐emitting diodes, offering great potential ...

Intrinsic chiroptical responsivity in self‐powered organic photodiodes for polarization‐tunable optical convolution

open access: yesInfoMat, EarlyView.
Self‐powered chiral organic photodiodes function as polarization‐sensitive convolutional filters for circularly polarized light‐driven optical convolutional neural networks. This conceptually innovative architecture enables dynamic weight modulation, bias‐free operation, and exceptional noise resilience, boosting feature extraction fidelity from 0.15 ...

Designing chiral organic small molecules for circularly polarized light detection via group theory

open access: yesInfoMat, EarlyView.
The chiral point group determines the arrangement of the μ‐m of chiral organic small molecules, thereby influencing their chiral photoelectric properties. In particular, chiral molecules with the D2 point group can effectively align the μ‐m to be either 0° or 180°, an effective strategy for high‐performance circularly polarized light photodetectors ...

Identifying Meat from Grazing or Feedlot Yaks Using Visible and Near-infrared Spectroscopy with Chemometrics

open access: yes
International audienceThe quality of meat can differ between grazing and feedlot yaks. The present study examined whether spectral fingerprints by visible and near -infrared (Vis-NIR) spectroscopy and chemo-metrics could be employed to identify the meat ...
