Tree shrews (TSs) possess a highly developed visual system. Here, we establish an age-related single-cell RNA sequencing atlas of retina cells from 15 TSs, covering 6 major retina cell classes and 3 glial cell types. An age effect is observed on the cell subset composition and gene expression pattern.

The primary symptom of Alzheimer's disease is a decrease in synaptic potency along with synaptic connection loss. Synapses, which act as important linkages between neuronal units within the cerebral region, are critical in signal transduction processes essential to orchestrating cognitive tasks.

Cases of hyperthyroidism presenting with coronary vasospasm are rarely reported. Herein, we present a case of a 54-year male patient with recurrent left chest pain for 2 months.

Receptor-interacting protein kinase-3 (RIPK3) and mixed lineage kinase domain-like (MLKL)-driven necroptosis plays an important role in cell fate. Previous research has shown that inhibition of RIPK1 activity alone did not attenuate SIN.
View Article and Find Full Text PDFSynaptic dysfunction is one of the earliest pathological processes that contribute to the development of many neurological disorders, including Alzheimer's disease and frontotemporal lobar degeneration. However, the synaptic function of many disease-causative genes and their contribution to the pathogenesis of the related diseases remain unclear. In this study, we investigated the synaptic role of fused in sarcoma, an RNA-binding protein linked to frontotemporal lobar degeneration and amyotrophic lateral sclerosis, and its potential pathological role in frontotemporal lobar degeneration using pyramidal neuron-specific conditional knockout mice (FuscKO).

The underlyi\ng mechanism remains to be elucidated. Gasdermin D (GSDMD)-mediated pyroptosis is a form of inflammatory cell death and participates in a variety of neurodegenerative diseases.

Fused in sarcoma (FUS) is an RNA-binding protein pathogenetically linked to Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Lobar Degeneration (FTLD) disease, yet the function of FUS on neurodevelopment is remained to be defined. Here we report a pivotal role of FUS in regulating the human cortical brain and spinal cord development via the human iPSCs-derived organoids.

Compared to idiopathic Parkinson's disease (iPD), PARK14 has several atypical clinical features. PARK14 has an earlier age at onset and is more likely to develop levodopa-induced dyskinesia.

Methods: A total of 120 patients with post-stroke dysphagia were randomized into an observation group and a control group, 60 patients in each one. The conventional swallowing rehabilitation therapy and respiratory function training were adopted in the control group.

We study the effects of non-Hermiticity on quantum coherence via a noisy quantum kicked rotor (NQKR). The random noise comes from the fluctuations in kick amplitude at each time. The non-Hermitian driving indicates the imaginary kicking potential, representing the environment-induced atom gain and loss.
View Article and Find Full Text PDFLong noncoding RNAs (lncRNAs) are known to regulate DNA damage response (DDR) and genome stability in proliferative cells. However, it remains unknown whether lncRNAs are involved in these vital biological processes in post-mitotic neurons. Here, we report and characterize a lncRNA, termed Brain Specific DNA-damage Related lncRNA1 (BS-DRL1), in the central nervous system.

Methods: The medical records of patients with mid-low rectal cancer who underwent SCRT or CRT were retrospectively analyzed. Differences in the treatment response, pathologic complete response (pCR), R0 resection, local recurrence, anastomotic leakage, presacral infection, anal preservation, defunctioning stoma, treatment-emergent adverse events (TEAEs), overall survival (OS) and disease-free survival (DFS) between patients who underwent SCRT and CRT were compared.
Objective: To observe the relationship between the analgesic effect of balance acupuncture and functional changes in brain in patients with migraine without aura.
Methods: A total of 40 cases of migraine without aura were equally randomized into a headache-acupoint group and a sham-acupoint group. When acupuncture given, a filiform needle was inserted into the headache-acupoint (the midpoint of the depression region anterior to the juncture of the first and second metatarsal bones on the dorsum of the foot) or the sham point (the midpoint of the depression region anterior to the juncture site between the 3 and 4 metatarsal joints of the dorsum of the foot) about 25-40 mm deep and manipulated for a while till the patient experienced feelings of electric shock and numbness, then withdrawn immediately.
The level of cerebellar activity in stroke patients has been shown to correlate with the extent of functional recovery. We reasoned that the cerebellum may be an important player in post-stroke rehabilitation. Because the neurons in the deep cerebellar nuclei (DCN) represent virtually all of the output from the cerebellum, in this study, using environmental enrichment (EE) to promote rehabilitation, we investigated the influence of the optogenetic neuronal modulation of DCN on EE-induced rehabilitation.

Adopting a suitable PEEP may prevent postoperative pulmonary complications. Robot-assisted laparoscopic surgery is the newest and most minimally invasive treatment for bladder cancer or prostate cancer.

However, determining the best hypothermia therapy strategy remains a challenge. We hypothesized that reducing the metabolic rate, rather than reaching a fixed body temperature, would be an appropriate target because optimizing metabolic conditions especially the brain metabolic environment may enhance neurologic protection.

View Article and Find Full Text PDFIt is well established that developmental exposure of sevoflurane (an inhalational anesthetic) is capable of inducing neuronal apoptosis and subsequent learning and memory disorders. Synaptic NMDA receptors activity plays an essential role in cell survival, while the extra-synaptic NMDA receptors activation is usually associated with cell death. However, whether synaptic or extra-synaptic NMDA receptors mediate developmental sevoflurane neurotoxicity is largely unknown.
View Article and Find Full Text PDFAutosomal dominant mutations of the RNA/DNA binding protein FUS are linked to familial amyotrophic lateral sclerosis (FALS); however, it is not clear how FUS mutations cause neurodegeneration. Using transgenic mice expressing a common FALS-associated FUS mutation (FUS-R521C mice), we found that mutant FUS proteins formed a stable complex with WT FUS proteins and interfered with the normal interactions between FUS and histone deacetylase 1 (HDAC1). Consequently, FUS-R521C mice exhibited evidence of DNA damage as well as profound dendritic and synaptic phenotypes in brain and spinal cord.

However, the underlying mechanism remains unclear. The aim of this study was to determine whether roscovitine, an inhibitor of Cdk5, could reverse the heat hyperalgesia induced by peripheral injection of complete Freund's adjuvant (CFA) via the brain-derived neurotrophic factor (BDNF)-tyrosine kinase B (TrkB) signaling pathway in the dorsal horn of the spinal cord in rats.
