Tannin-Derived Hard Carbon for Stable Lithium-Ion Anode.

Graphite anodes are well established for commercial use in lithium-ion battery systems. However, the limited capacity of graphite limits the further development of lithium-ion batteries. Hard carbon obtained from biomass is a highly promising anode material, with the advantage of enriched microcrystalline structure characteristics for better lithium storage.

Blood Pressure Trajectories From Childhood to Youth and Arterial Stiffness in Adulthood: A 30-Year Longitudinal Follow-Up Study.

Background: This study aimed to identify the subgroups of individuals sharing similar blood pressure (BP) trajectories from childhood to youth and explore the associations of these trajectories with arterial stiffness in adulthood.

Methods: A group-based trajectory model was used to identify BP trajectories among 2,082 individuals in the Hanzhong adolescent hypertension cohort by using BP values repeatedly measured at four visits from childhood (6-15 years) to youth (14-23 years). The brachial-ankle pulse wave velocity (baPWV) was examined 30 years after the baseline survey.

The effects and mechanisms of transcranial ultrasound stimulation combined with cognitive rehabilitation on post-stroke cognitive impairment.

Objective: To investigate whether transcranial ultrasound stimulation (TUS) could improve post-stroke cognitive impairment (PSCI) and the potential mechanisms through which this can be achieved.

Method: Sixty patients with PSCI were selected and randomly divided into a control and observation group, respectively, with 30 cases in each group. Conventional cognitive rehabilitation training combined with TUS intervention was conducted in the observation group, while conventional cognitive rehabilitation training and sham-TUS stimulation were given to patients in the control group.

A preliminary analysis of microRNA-21 expression alteration after antipsychotic treatment in patients with schizophrenia.

Schizophrenia is a severe and debilitating psychiatric disorder of unknown etiology, and its diagnosis is essentially based on clinical symptoms. Despite growing evidence on the relation of altered expression of miRNAs and schizophrenia, most patients with schizophrenia usually had an extensive antipsychotic treatment history before miRNA expression profile analysis, and the pharmacological effects on miRNA expression are largely unknown. To overcome these impediments, miRNA microarray analysis was performed in peripheral blood mononuclear cells (PBMCs) obtained from patients with schizophrenia who were not on antipsychotic medication and healthy controls.

Correlation between the level of microRNA expression in peripheral blood mononuclear cells and symptomatology in patients with generalized anxiety disorder.

This study investigated the correlation between the level of microRNA expression in peripheral blood mononuclear cells (PBMCs) and symptomatology in patients with generalized anxiety disorder (GAD). MicroRNA array was performed in peripheral blood mononuclear cells (PBMCs) obtained from GAD patients with gender, age, ethnicity-matched healthy controls. Then real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to verify the top 7 miRNAs with the highest fold-change values in 76 GAD patients and 39 healthy controls.

[Cryopreservation study on seeds and embryos in Dalbergia odorifera].

The mature seeds and excised embryos of Dalbergia odorifera were used as materials to study the effect of moisture content on their survival, as well as the effect of rapid freezing and vitrification freezing method on seeds and in vitro embryos cryopreservation. The results showed that the germination rate and vigor decreased from 82.67%, 85% to 18.
