Simultaneous Detection of GABA and Glycine Using MEGA‐PRESS With TE Optimization at 3T

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2479-2488, May 2026.
ABSTRACT Purpose To achieve the simultaneous acquisition of gamma‐aminobutyric acid (GABA) and glycine (Gly) using a MEGA‐PRESS sequence with an optimized TE at 3T. Methods MEGA‐PRESS simulations were performed at TEs 60‐88 ms to determine the optimal TE for Gly detection with minimal myo‐Inositol (mI) overlap and maximal GABA detection sensitivity ...

Photonic Crystal Fibers in the Terahertz Regime: Design Strategies, Performance Metrics, and Emerging Applications: A Systematic Review

open access: yesAdvanced Photonics Research, Volume 7, Issue 4, April 2026.
An optimized octagonal‐core terahertz (THz) photonic crystal fiber sensor is presented for accurate identification of different milk samples based on refractive index variation. The structure enables highly confined THz guidance and strong light–analyte interaction, allowing reliable discrimination of camel, cow, buffalo, and sheep milk.

Interaction of excitation and inhibition in processing of pure tone and amplitude-modulated stimuli in the medial superior olive of the mustached bat [PDF]

open access: yes, 1994
1. In mammals with good low-frequency hearing, the medial superior olive (MSO) processes interaural time or phase differences that are important cues for sound localization.

Hair cell maturation is differentially regulated along the tonotopic axis of the mammalian cochlea [PDF]

open access: yes, 2020
Sound amplification within the mammalian cochlea depends upon specialized hair cells, the outer hair cells (OHCs), which possess both sensory and motile capabilities.

NMDA Currents Modulate the Synaptic Input–Output Functions of Neurons in the Dorsal Nucleus of the Lateral Lemniscus in Mongolian Gerbils [PDF]

open access: yes, 2011
Neurons in the dorsal nucleus of the lateral lemniscus (DNLL) receive excitatory and inhibitory inputs from the superior olivary complex (SOC) and convey GABAergic inhibition to the contralateral DNLL and the inferior colliculi.

Formal Synthesis of the Akuammiline Alkaloid (±)‐Strictamine via a (4 + 2) Annulation Reaction With a Donor–Acceptor Cyclobutane

open access: yesHelvetica Chimica Acta, Volume 109, Issue 4, April 2026.
We report a concise formal synthesis of (±)‐strictamine via a silylium‐catalyzed (4 + 2) annulation of a donor–acceptor cyclobutane, achieved in 13 steps from tryptamine. ABSTRACT The akuammiline alkaloids are complex monoterpene indole natural products with a rigid cage‐like architecture and diverse biological activities.

Flexibility in the Patterning and Control of Axial Locomotor Networks in Lamprey [PDF]

open access: yes, 2011
In lower vertebrates, locomotor burst generators for axial muscles generally produce unitary bursts that alternate between the two sides of the body. In lamprey, a lower vertebrate, locomotor activity in the axial ventral roots of the isolated spinal ...
