Interaction of metabolic and inflammatory dysregulation on central degeneration and cognitive function in behavioral variant Frontotemporal dementia.

Background: Metabolic and inflammation dysregulation are important mechanisms in neurodegenerative diseases, but their study in behavioral variant frontotemporal dementia (bvFTD) is very scarce; we aimed to investigate the separate and interactive effects of metabolic and inflammatory dysregulation on central degeneration and cognitive function in patients with bvFTD.

Methods: This study recruited participants with bvFTD and healthy controls (HC) from December 15, 2017, to September 5, 2024, in the Department of Neurology of Xuanwu Hospital, underwent assessment of plasma targeted metabolite, plasma inflammatory factors, 18F-fludeoxyglucose-positron emission tomography/magnetic resonance imaging, and neuropsychological assessments. Linear regression models and interaction models were implemented using age, sex and education level as covariates to explore the association between differential metabolites and peripheral inflammatory markers with neuroimaging, and clinical measures.

Femtosecond laser trapping nanoprinting of silver micro/nanostructures.

In this paper, silver micro/nanostructures composed of sintered nanoparticles were printed by capturing silver nanoparticles in water with 800 nm femtosecond laser trapping. Relationships of laser power, scanning speed, nanoparticle concentration, and the width and morphology of fabricated silver wire were systematically investigated. It is found that low scanning speed and high nanoparticle concentration favor the printing of silver wire with good morphology.

A Non-Lipolysis Nanoemulsion Improved Oral Bioavailability by Reducing the First-Pass Metabolism of Raloxifene, and Related Absorption Mechanisms Being Studied.

Objective: A non-lipolysis nanoemulsion (NNE) was designed to reduce the first-pass metabolism of raloxifene (RAL) by intestinal UDP-glucuronosyltransferases (UGTs) for increasing the oral absorption of RAL, coupled with in vitro and in vivo studies.

Methods: In vitro stability of NNE was evaluated by lipolysis and the UGT metabolism system. The oral bioavailability of NNE was studied in rats and pigs.

Early neutrophil count relates to infarct size and fatal outcome after large hemispheric infarction.

Aims: To investigate the relationship between peripheral leukocyte dynamics and the outcome of large hemispheric infarction (LHI) patients.

Methods: Patients with acute LHI admitted to the neuro-intensive care unit of Xuanwu Hospital from 2013 to 2017 were prospectively enrolled and followed up for 6 months after LHI.

Results: A total of 84 LHI patients were included, 38 patients suffered brain herniation and 20 patients died from stroke.

Neurophysiological predictors of aphasia recovery in patients with large left-hemispheric infarction: a mismatch negativity study.

Background: Although the rehabilitation of aphasia has been extensively studied, the prediction of language outcome still has not received sufficient attention. The aim of this study was to predict the language outcome using mismatch negativity (MMN) in patients with large left-hemispheric infarction.

Methods: MMN was elicited by an oddball paradigm in which a standard tone (1000 Hz) and deviant tone (1500 Hz) were presented at 90% and 10% of the number of tones, respectively.

[Contribution of anaerobic oxidation of methane to whole methane oxidation].

The contribution of anaerobic methane oxidation to the whole methane oxidation is investigated by monitoring the activities of anaerobic and aerobic oxidation of methane in paddy soils composed mechanically of <0.02 mm and > 0.02 mm soil granules, contained different water contents, and long-term fertilized organic manure or inorganic nitrogen, phosphorus and potassium fertilizers.

Effects of butachlor on microbial enzyme activities in paddy soil.

This paper reports the influences of the herbicide butachlor (n-butoxymethl-chloro-2', 6'-diethylacetnilide) on microbial respiration, nitrogen fixation and nitrification, and on the activities of dehydrogenase and hydrogen peroxidase in paddy soil. The results showed that after application of butachlor with concentrations of 5.5 micrograms/g dried soil, 11.
