CEOs' leadership behaviors and new venture team stability: The effects of knowledge hiding and team collectivism.

Purpose: The reasons for new venture team instability gradually have become a vital issue in the entrepreneurship literature. While chief executive officers' (CEOs) leadership behaviors is regarded as a critical element of governance within new venture teams, few studies explored the role played by CEOs' leadership behaviors in new venture team stability. Drawing on the transactional-transformational leadership model, this study divides CEOs' leadership behaviors in new ventures into two categories, namely, transformational and transactional leadership behaviors.

Integrating Lipidomics and Transcriptomics Reveals the Crosstalk Between Oxidative Stress and Neuroinflammation in Central Nervous System Demyelination.

Multiple sclerosis (MS) is an incurable and progressive neurodegenerative disease that affects more than 2.5 million people worldwide and brings tremendous economic pressures to society. However, the pathophysiology of MS is still not fully elucidated, and there is no effective treatment.

Platform Leadership and Sustainable Competitive Advantage: The Mediating Role of Ambidextrous Learning.

In the context of the knowledge economy, the role of traditional leadership for enterprises is questioned. Based on contingency theory and the resource-based view, this paper proposes the important role of platform leadership, a new leadership type in line with the context of the times, for a sustainable competitive advantage. We conducted an empirical study to examine and confirm the positive effects of platform leadership on sustainable competitive advantage and ambidextrous learning.

Chinese Admission Warning Strategy for Predicting the Hospital Discharge Outcome in Patients with Traumatic Brain Injury.

Objective: To develop and validate an admission warning strategy that incorporates the general emergency department indicators for predicting the hospital discharge outcome of patients with traumatic brain injury (TBI) in China.

Methods: This admission warning strategy was developed in a primary cohort that consisted of 605 patients with TBI who were admitted within 6 h of injury. The least absolute shrinkage and selection operator and multivariable logistic regression analysis were used to develop the early warning strategy of selected indicators.

Untargeted Metabolomic Profiling of Cuprizone-Induced Demyelination in Mouse Corpus Callosum by UPLC-Orbitrap/MS Reveals Potential Metabolic Biomarkers of CNS Demyelination Disorders.

Multiple sclerosis (MS) is a neurodegenerative disorder characterized by periodic neuronal demyelination, which leads to a range of symptoms and eventually to disability. The goal of this research was to use UPLC-Orbitrap/MS to identify validated biomarkers and explore the metabolic mechanisms of MS in mice. Thirty-two C57BL/6 male mice were randomized into two groups that were fed either normal food or 0.

Case Report: Direct Visualization of the Nervus Intermedius During the Microvascular Decompression Procedure: Should We Take It Seriously?

Nervus intermedius neuralgia (NIN), known as geniculate neuralgia (GN), is an uncommon cranial nerve disease caused by an offending vessel compressing the nervus intermedius (NI). Microvascular decompression (MVD) has now become a valued treatment approach for NIN because it can resolve neurovascular conflict (NVC) at the root entry zone of the NI. In the era of continuously optimizing and improving the surgical technique of MVD, further minimization of all possible postoperative complications is not only welcome but also necessary.

Integration of single-cell and bulk RNA sequencing data reveals key cell types and regulators in traumatic brain injury.

Traumatic brain injury (TBI) is a leading cause of disability and mortality worldwide, whose symptoms ranging from mild to severe, even life-threatening. However, specific cell types and key regulators involved in traumatic brain injury have not been well elucidated. In this study, utilizing single-cell RNA-seq (scRNA-seq) data from mice with TBI, we have successfully identified and characterized 13 cell populations including astrocytes, oligodendrocyte, newly formed oligodendrocytes, microglia, two types of endothelial cells, five types of excitatory and two types of inhibitory neurons.

Analysis of Failed Microvascular Decompression in Patients with Trigeminal Neuralgia.

 Microvascular decompression (MVD) has been widely accepted as a definitive therapy for primary trigeminal neuralgia (TN). However, some patients may not experience relief of TN symptoms following surgery. In this study, the findings of redo MVD are discussed.

Improvement of quality of life and mental health in patients with spasmodic torticollis after microvascular decompression.

Objective: Although not life threatening, spasmodic torticollis (ST) impairs patients' daily activity, socialization and work. The aim of this study was to evaluate the quality of life (QOL) and mental health in patients with ST after microvascular decompression (MVD).

Patients And Methods: From June 2014 to June 2017, patients with ST who underwent MVD in our department were included in this study.

New Rhizotomy Procedure for Primary Spasmodic Torticollis.

Objective: Spasmodic torticollis (ST) is an idiopathic neurologic disorder affecting the muscles of the neck. Surgery is a preferred treatment, when conservative treatments or Botulinum neurotoxin injections fail to relieve the symptoms. Our objective here is to report the outcome of a new surgical method for treating ST patients in our department.

Residual hemifacial spasm after microvascular decompression: prognostic factors with emphasis on preoperative psychological state.

Residual hemifacial spasm (HFS) after microvascular decompression (MVD) is common, and the factors associated with residual HFS are still controversial. In the present study, we analyzed the outcome of 212 patients with hemifacial spasm after a single microvascular decompression and evaluated the prognostic factors involved in residual hemifacial spasm. Based on our study, possible prognostic factors included indentation of the root exit zone (REZ), preoperative illness duration, and preoperative psychological state.

Seizure outcome after surgical resection of supratentorial cavernous malformations plus hemosiderin rim in patients with short duration of epilepsy.

Objective: The objective of this study was to retrospectively review the postoperative seizure outcome in patients with short duration of epilepsy associated with cavernous malformations and analyze the effect of surgical methods on seizure outcome in such population.

Methods: 36 patients with short duration of epilepsy (shorter than 12 months) associated with cavernous malformations in temporal or frontal lobe underwent microsurgical resection. The patients were retrospectively divided into two groups: Group A (21 patients) with complete removal of hemosiderin rim and Group B (15 patients) with partial removal of hemosiderin rim.

The association between post-traumatic stress disorder symptoms and the quality of life among Wenchuan earthquake survivors: the role of social support as a moderator.

Objective: To examine the role of the three types of social support as possible moderating factors between post-traumatic stress disorder (PTSD) and its relationship to two domains of the quality of life (QOL).

Methods: A cross-sectional survey was done in a local area near the epicenter of the severe earthquake in Wenchuan. The Diagnostic and statistical manual of mental disorders, fourth edition (DSM-IV), the standard Chinese 12-item Short Form (SF-12v2), and the Social Support Rating Scale (SSRS) were used to interview a total of 2,080 earthquake survivors in the one-year follow-up period.

Preventive effects of low molecular mass potassium alginate extracted from brown algae on DOCA salt-induced hypertension in rats.

Available evidence indicates that brown algae may be beneficial for the treatment of high blood pressure. Our recent study demonstrated that low molecular mass potassium alginate (L-PA), one of the major polysaccharides extracted from brown algae, decreased systolic blood pressure (SBP) in spontaneous hypertensive rats. The present study investigated the effects of L-PA on deoxycorticosterone acetate (DOCA) salt-induced hypertension in rats.

[Antihypertensive effect and pharmacokinetics of low molecular mass potassium alginate].

Objective: To investigate the effect of low molecular weight potassium alginate (L-PA) on blood pressures in spontaneously hypertensive rats (SHRs) and its pharmacokinetics characteristics in mice.

Methods: The systolic blood pressure (SBP) was measured by tail-cuff method in conscious SHRs. Forty rats were randomly assigned to the following five groups: control, hydrochlorothiazide (HCT, 6.
