Effects of early antihypertensive treatment on cognitive function in patients with acute ischemic stroke with different neurofilament light chain levels.

Background: It is unclear whether the extent of neuroaxonal damage, as measured by circulating levels of neurofilament light chain (NfL), would modify the effects of early antihypertensive therapy on cognitive performance following stroke. This study aimed to investigate the effects of early blood pressure reduction on the risk of post-stroke cognitive impairment (PSCI) among patients with different plasma NfL levels.

Methods: A total of 622 eligible patients from a pre-planned ancillary study of CATIS (China Antihypertensive Trial in Acute Ischemic Stroke) were included in this study.

[Salidroside alleviates high glucose and ethanol-induced pyroptosis in insulinoma cells].

This study established a pyroptosis injury model by stimulating insulinoma cells(INS-1) of rats with high glucose(HG) and observed the impact of additional ethanol(ET) exposure on cell pyroptosis, as well as the intervention effect of salidroside(SAL). INS-1 cells were cultured and divided into a normal control group(NG), an HG group, an HG + ET(100 mmol·L~(-1)) group, and an HG + ET + SAL(1-100 μmol·L~(-1)) group. After 72 hours of treatment, cell viability was assessed using the cell counting kit-8(CCK-8) assay.

High plasma thrombomodulin level is associated with a decreased risk of cognitive impairment after ischemic stroke.

This study aimed to prospectively examine the association between plasma NPY levels and adverse clinical outcomes after acute ischaemic stroke.

Methods: Plasma NPY levels were measured in 3250 patients (2066 men and 1184 women) from the China Antihypertensive Trial in Acute Ischaemic Stroke.

Lewis Acidic Ionic-Liquid-Catalyzed Radical-Cascade Alkylation/Cyclization of -Alkyl--methacryloyl Benzamides with Alkanes via Visible-Light-Induced Ligand-to-Metal Charge Transfer: Access to Alkylated Isoquinoline-1,3(2,4)-diones.

With the flourishing progress of ligand-to-metal charge transfer (LMCT) photocatalysis, various metals were developed as catalysts to activate abundant alkane feedstocks for the synthesis of functionalized organic compounds. However, to the best of our knowledge, most of the LMCT catalysts are difficult to recover and reuse for the next cycles. Herein, we report a reusable Lewis acidic ionic liquid (LAIL)-catalyzed radical-cascade alkylation/cyclization of -alkyl--methacryloyl benzamides with unactivated alkanes for the synthesis of alkylated isoquinoline-1,3-(2,4)-diketones.

Effects of different doses of rituximab on immunoglobulin levels in high-risk pediatrics with Burkitt's lymphoma.

Studies have confirmed that rituximab (RTX) can improve the efficacy of BL, but there is a certain effect on the level of immunoglobulin, which will lead to the verification of infection, and the previous study of our center has confirmed that reducing the dose of RTX (4 doses) can achieve a similar effect to the standard dose of RTX (6 doses), can it reduce the effect on the level of immunoglobulin? To date, few studies have concentrated on the effects of immunoglobulin (Ig) on Chinese paediatric patients. This study aimed to examine whether there is a variation in the impact of different doses of RTX on immunoglobulin levels in the high-risk group of children with BL. Clinical data of high-risk pediatric patients with BL who were treated in Beijing Children's Hospital (Beijing, China) were retrospectively analysed.

Unearthing the Real-Time Excited State Dynamics from Antenna to Rare Earth Ions Using Ultrafast Transient Absorption.

The conventional energy transfer pathway in organic lanthanide complexes is purported to be from the excited singlet state of the chromophore to the triplet state and subsequently directly to the emitting state of the trivalent lanthanide ion. In this work, we found that the energy transfer occurs from the triplet state to the nearest energy level, instead of directly to the emitting state of the lanthanide ion. The triplet decay rate for different lanthanide ions follows an energy gap law from the triplet level to the receiving level of the lanthanide ion.
