The product formula for Lusternik-Schnirelmann category

, 2001
If C=C_\phi denotes the mapping cone of an essential phantom map \phi from the suspension of the Eilenberg-Mac Lane complex K=K(Z,5) to the 4-sphere S=S^4 we derive the following properties: (1) The LS category of the product of C with any n-sphere S^n ...

A Tac1‐Expressing Brainstem Pathway Underlies the Pathogenesis of Trigeminal Neuralgia

Advanced Science, EarlyView.
A critical TG‐Sp5CTac1‐PBNTac1 pathway drives trigeminal neuropathic pain (TNP). Tac1‐expressing parabrachial nucleus (PBNTac1) neurons exhibit heightened responses to innocuous stimuli in TNP, and chemogenetic inhibition of these neurons effectively prevents TNP development.

Photothermal Transport for Guiding Nanoparticles Through the Vitreous Humor

Advanced Science, EarlyView.
Nanosecond laser irradiation of the clinically approved dye indocyanine green (ICG) enables light‐guided nanoparticle transport within the vitreous humor. The combined use of ICG and pulsed laser illumination induces localized convection and thermophoresis, directing particles toward illuminated regions.

Respiratory‐Limbic Coupling via a Thalamic Circuit Alleviates Anxiety

Advanced Science, EarlyView.
This study delineates a conserved preBötCGlu→PVT→CeA circuit that gates anxiety and respiration. Activation of this circuit is anxiolytic and respiratory‐stabilizing, while its inhibition has the opposite effect. Mechanistically, PVT exerts its anxiolytic action via a disinhibitory microcircuit: its inputs preferentially target CeL GABAergic neurons ...

Keratorefractive lenticule extraction (KLEx) versus femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for the treatment of myopia and compound myopic astigmatism: study protocol of a randomised clinical trial in Mexico

BMJ Open
Introduction Kerato-lenticule extraction (KLEx) is a refractive surgery technique that, in contrast with femtosecond laser-assisted in situ keratomileusis (FS-LASIK), does not require the creation of a flap to correct refractive defects.

Clinical and microbiological profile of patients with fungal keratitis demonstrating unusual yeast-like structures in potassium hydroxide with calcofluor white preparation of corneal scraping

Journal of Ophthalmic Inflammation and Infection
Background To report a case series of microbial keratitis showing atypical yeast-like structures in direct microscopy which were culture-negative but subsequently identified as yeast cells by PCR and DNA sequencing. Main text This is a retrospective, non-

PVNCRF Neurons Regulate Migraine‐Like Allodynia by Activating CRFR2 on Spinal Trigeminal Caudalis Glutamatergic Neurons

Advanced Science, EarlyView.
Paraventricular CRF neurons in the hypothalamus project to glutamatergic neurons of the spinal trigeminal caudal nucleus, enhancing neuronal activation and CRFR2 signaling. This pathway increases CRF release and excitatory drive, promoting central sensitization and migraine‐related behaviors. Targeting the PVN–SP5C circuit provides a potential strategy
