Background: Post-stroke cognitive impairment (PSCI) not only increases patient mortality and disability, but also adversely affects motor function and the ability to perform routine daily activities. Current therapeutic approaches for, PSCI lack specificity, primarily relying on and medication and traditional cognitive therapy supplemented by a limited array of tools. Both transcranial direct current stimulation (tDCS) and virtual reality (VR) training have demonstrated efficacy in improving cognitive performance among PSCI patients.

Article Synopsis
  • Spinocerebellar ataxia type 3 (SCA3) is a hereditary condition with varied clinical patterns, including one form marked by spastic paraplegia, leading researchers to examine its features and progression.
  • A study involving 249 SCA3 patients was conducted, focusing on two groups: those with spastic paraplegia (SCA3-SP) and those without (SCA3-NSP), using advanced brain imaging techniques to analyze differences.
  • The results indicated that SCA3-SP patients were younger and had more severe symptoms, as shown by higher clinical scores and larger genetic markers, compared to the SCA3-NSP group, highlighting differences in disease progression between the two subtypes

Article Synopsis
  • - Repetitive transcranial magnetic stimulation (rTMS) shows potential for treating spinocerebellar ataxia type 3 (SCA3), though its effectiveness and underlying mechanisms are not fully understood.
  • - In a study, 22 SCA3 patients received either actual rTMS or a sham treatment for 15 days, with the real rTMS group showing a greater improvement in motor function as measured by ICARS scores.
  • - Results from resting-state fMRI indicated that rTMS led to increased brain activity in specific regions, suggesting it may enhance motor functions in SCA3 patients by affecting brain excitability and function.

Background: In a previous study, more attention has been given to the psychological state of doctors than to that of nurses although the workload, working hours, and patient contact time are generally higher for nurses than doctors. The current status of nurses' perceived stress, work engagement, and perceived professional benefit during the routine management of the Coronavirus disease 2019 (COVID-19) pandemic and how their perceived stress affects the other two variables are topics that merit research attention.

Objective: In this study, the status of nurses' perceived stress, work engagement, and perceived professional benefit during the routine management of the COVID-19 pandemic was investigated to explore whether their perceived stress level has any effect on the other two variables.

The present case study reported a patient diagnosed with hypertrophic olivary degeneration, a rare condition characterized by a trans-neuronal degeneration and signal enhancement in T2-weighted images on magnetic resonance imaging, usually caused by cerebral hemorrhage, cerebral infarction, and trauma. Furthermore, the relevant literature review was performed. The existing pharmacological treatment has limited clinical benefits on the patient.

Ataxia-ocular apraxia 2 (AOA2) is a rare neurodegenerative autosomal recessive disorder with no effective treatment. In this study, we present the case of a patient diagnosed with AOA2, who experienced walking instability and uncoordinated movement. The patient underwent transcranial alternating current stimulation (tACS) treatment for 4 weeks with follow-up after 1 month.

BACKGROUND Inspiratory muscle training (IMT) aims to train inspiratory muscles based mainly on the diaphragm by applying a load resistance during the inspiratory process. Many papers related to IMT have been published in various journals; however, no articles objectively and directly present the development trends and research hotspots of IMT. Therefore, this study used CiteSpace to visually analyze recent IMT-related publications to provide valuable information for future IMT-related studies.

Background: Cerebellar ataxia (CA) is a movement disorder that can affect balance and gait, limb movement, oculomotor control, and cognition. Multiple system atrophy-cerebellar type (MSA-C) and spinocerebellar ataxia type 3 (SCA3) are the most common forms of CA, for which no effective treatment is currently available. Transcranial alternating current stimulation (tACS) is a non-invasive method of brain stimulation supposed to alter cortical excitability and brain electrical activity, modulating functional connectivity within the brain.

Article Synopsis
  • - Researchers investigated modifications to Combretastatin A-4 (CA-4) to enhance its low solubility and improve its effectiveness as a cancer treatment.
  • - They found that adding a piperazine ring significantly increased the solubility of CA-4 derivatives, with some compounds showing solubility improvements of 230 to 2494 times compared to the control.
  • - The new compounds demonstrated strong anticancer activity against various cancer cell lines, with one compound showing an IC50 value of 20 nM against HCT-116 cells, indicating potential for drug development due to its good plasma stability and moderate protein binding.

Objectives: Spinocerebellar ataxia type 3 is a disorder within the brain network. However, the relationship between the brain network and disease severity is still unclear. This study aims to investigate changes in the white matter (WM) structural motor network, both in preclinical and ataxic stages, and its relationship with disease severity.

Background: Genetic variants in (also known as ) have been reported to have significant associations with asthma and eczema in special populations, but little is known about allergic rhinitis. This study purposes to evaluate the association of single nucleotide polymorphisms (SNPs) in with house dust mite (HDM)-sensitized persistent allergic rhinitis (PER) in a population of Han Chinese.

Methods: In this hospital-based case-control study, 534 HDM-sensitized PER patients and 451 healthy controls were recruited from East China.

Background: Spinocerebellar ataxia type 3 (SCA3) is the most common autosomal dominant hereditary ataxia, and, thus far, effective treatment remains low. Repetitive transcranial magnetic stimulation (rTMS) can improve the symptoms of spinal cerebellar ataxia, but the mechanism is unclear; in addition, whether any improvement in the symptoms is related to cerebellar metabolism has not yet been investigated. Therefore, the purpose of this study was to investigate the effects of low-frequency rTMS on local cerebellar metabolism in patients with SCA3 and the relationship between the improvement in the symptoms and cerebellar metabolism.

Objective: To develop a machine learning (ML)-based classifier for discriminating between low-grade (ISUP I-II) and high-grade (ISUP III-IV) clear cell renal cell carcinomas (ccRCCs) using MRI textures.

Materials And Methods: We retrospectively evaluated a total of 99 patients (with 61 low-grade and 38 high-grade ccRCCs), who were randomly divided into a training set ( = 70) and a validation set ( = 29). Regions of interest (ROIs) of all tumors were manually drawn three times by a radiologist at the maximum lesion level of the cross-sectional CMP sequence images.

Objective: To investigate the response of the infrapatellar fat pad (IFP) to running at different intensities and further explore the underlying mechanisms of these responses under different running-induced loadings.

Methods: Animals were randomly assigned into the sedentary (SED), low-intensity running (LIR), medium-intensity running (MIR), and high-intensity running (HIR) groups. The rats in the LIR, MIR, and HIR groups were subjected to an 8-week treadmill running protocol.

Members of species complex (FGSC) are the major pathogens that cause Fusarium head blight (FHB) in cereals worldwide. Symptoms of FHB on rice, including dark staining or browning of rice glumes, were recently observed in Jiangsu Province, China. To improve our understanding of the pathogens involved, 201 FGSC isolates were obtained from freshly harvested rice samples and identified by phylogenetic analyses.

Obstructive sleep apnea (OSA) is a common clinic sleep disorder, and characterized by obstruction of upper airway during sleep, resulting in sleep fragmentation and intermittent hypoxemia. We reviewed the brain imaging studies in OSA patients compared with healthy subjects, including studies of functional magnetic resonance imaging (fMRI) and electroencephalography (EEG). The resting-state EEG studies showed increased power of δ and θ in the front and central regions of the cerebral cortex in OSA patients.
