The Amphioxus SoxB Family: Implications for the Evolution of Vertebrate Placodes [PDF]

open access: yes, 2007
Cranial placodes are regions of thickened ectoderm that give rise to sense organs and ganglia in the vertebrate head. Homologous structures are proposed to exist in urochordates, but have not been found in cephalochordates, suggesting the first chordates

Olfactory Bulb Volume Reflects Olfactory Dysfunction and Network Organization: Insights From the Population‐Based Rhineland Study

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory dysfunction is common in aging and an early symptom of neurodegenerative diseases, but how structural (olfactory bulb [OB] volume) and functional (olfactory network [OFN] functional connectivity [FC]) brain features interact to shape odor identification ability remains unclear.

Neural stem cells transplantation combined with ethyl stearate promotes the activation of quiescent NSCs and improves PD rats motor behavior

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Co‐transplantation of ethyl stearate and NSCs can effectively improve motor dysfunction in PD rats and ethyl stearate regulates the entry into and exit from the quiescent state of NSCs through the EphB2/AKT/CyclinD1 pathway. Abstract Background This research aimed to examine the impact of co‐transplantation of ethyl stearate (PubChem CID: 8122) and ...

Identification of candidate olfactory genes in Leptinotarsa decemlineata by antennal transcriptome analysis

open access: yesFrontiers in Ecology and Evolution, 2015
The sense of smell is critical for the survival of insects, by which insects detect the odor signals in the environment and make appropriate behavioral responses such as host preference, mate choice, and oviposition site selection.

Serum p‐tau217 Is a Prognostic Indicator of Cognitive Impairment in Idiopathic REM Sleep Behavior Disorder

open access: yesAnnals of Neurology, EarlyView.
Objective Assess the performance of serum phosphorylated tau 217 (p‐tau217) and neurofilament light chain (NfL) in predicting risk of cognitive impairment or phenoconversion to dementia in individuals with iRBD. Methods We measured serum p‐tau217 and NfL levels by electrochemiluminescence across 4 polysomnographically confirmed iRBD cohorts (n = 300 ...

Nanomaterial‐Mediated Near‐Infrared Photothermal Neuromodulation for Neurologic Disorders

open access: yesAdvanced NanoBiomed Research, EarlyView.
This review summarizes how near‐infrared light activates photothermal nanomaterials to enable noninvasive neuromodulation with high spatiotemporal precision. It elucidates the underlying mechanisms, explores targeted therapeutic applications for neurological disorders, discusses integration with optogenetics and biosensors, and addresses future ...

Analysis of the goldfish Carassius auratus olfactory epithelium transcriptome reveals the presence of numerous non-olfactory GPCR and putative receptors for progestin pheromones

open access: yesBMC Genomics, 2008
Background The goldfish (Carassius auratus) uses steroids and prostaglandins as pheromone cues at different stages of the reproductive cycle to facilitate spawning synchronization.

Unlocking fruit dimensions: Quantification of functional traits driving plant–frugivore interactions

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Fleshy fruits attract animals to ingest fruit, swallow the seeds, and release them in the landscape, thus facilitating seed dispersal and plant regeneration. Attraction of animal dispersers is achieved via attractants such as color or scent, and rewards like sugars, lipids, and micronutrients.

Animal‐mediated seed dispersal: A review of study methods

open access: yesApplications in Plant Sciences, EarlyView.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.
