Effect of subanesthetic dose of esketamine on early postoperative depression in elderly patients with Sarcopenia.

Objective: To explore the effects of subanesthetic dose of esketamine on serum inflammatory factor levels and depressive mood in elderly patients with sarcopenia postoperatively.

Methods: This study retrospectively included 102 elderly patients who underwent elective total knee arthroplasty from April 2023 to June 2024 with skeletal muscle mass index (SMI) meeting the diagnostic criteria for sarcopenia (male SMI < 42.6 cm/m, female SMI < 30.

Cell membrane patches transfer CAR molecules from a cellular depot to conventional T cells for constructing innovative fused-CAR-T cells without necessitating genetic modification.

Chimeric antigen receptor (CAR) serves as the foundational element of CAR-T cells. Exogenous CAR molecules can exert functional effects on allogeneic T cells, leading to their activation and subsequent functional alterations. Here we show a new method based on this biological principle: the transfer of CAR molecules from exogenous cells to the membrane of receptor T cells.

Engineering M1 macrophages with targeting aptamers for enhanced adoptive immunotherapy by modifying the cell surface.

Macrophages play a critical role in the body's defense against cancer by phagocytosing tumor cells, presenting antigens, and activating adaptive T cells. However, macrophages are intrinsically incapable of delivering targeted cancer immunotherapies. Engineered adoptive cell therapy introduces new targeting and antitumor capabilities by modifying macrophages to enhance the innate immune response of cells and improve clinical efficacy.

Uncovering novel drug targets for bipolar disorder: a Mendelian randomization analysis of brain, cerebrospinal fluid, and plasma proteomes.

Background: There is a clear demand for innovative therapeutics for bipolar disorder (BD).

Methods: We integrated the largest BD genome-wide association study (GWAS) dataset ( = 41 917, = 371 549) with protein quantitative trait loci from brain, cerebrospinal fluid, and plasma. Using a range of integrative analyses, including Mendelian randomization (MR), Steiger filter analysis, Bayesian colocalization, and phenome-wide MR analysis, we prioritized novel drug targets for BD.

Enhanced removal strategy towards organic matter with low coagulability: Immediate entrapment and complexation of oxidized intermediates by the hybrid ozonation-coagulation process.

The existence of dissolved organic matter (DOM) with low coagulability poses great challenges for conventional coagulation (CC) in water treatment. As a kind of typical organochlorine pesticide, 2,4-dichlorophenoxyacetic acid (2,4-D) cannot be efficiently removed by CC. To enhance the 2,4-D removal, ozonation was applied with coagulation.

Unraveling the over-oxidation inhibition mechanism during the hybrid ozonation-coagulation process: Immediate entrapment and complexation between intermediate organic matter and coagulants.

Pre-ozonation coagulation process had a very low and narrow range of ozone dosages for enhancing the dissolved organic matter (DOC) removal efficiency, in which over-oxidation may occur if the ozone dosage was not strictly controlled. In contrast, the proposed hybrid ozonation-coagulation (HOC) process with higher oxidation ability notably inhibited over-oxidation in this study, and exhibited improved DOC removal efficiency compared with coagulation at a much wider range of ozone dosages at different initial pH for the treatment of WWTP effluent. The HOC process also had a higher DOC removal efficiency than pre-ozonation coagulation.

Electro-dissolved ozone flotation (E-DOF) integrated anoxic/oxic membrane reactor for leachate treatment from a waste transfer station.

With high organics and ammonia, leachate from waste transfer stations (WTSs) is among the most complex wastewater that cannot be easily disposed by signal biological processes. In this study, an electro-dissolved ozone flotation (E-DOF) was established, in which dissolved ozone flotation (DOF) and electro-coagulation (EC) occurred concurrently in one unit and integrated with anoxic/oxic membrane bioreactor (A/O-MBR) to dispose leachate from a WTS. In the integrated reactor, E-DOF acted as pretreatment and advanced treatment unit.

Characteristics of dissolved ozone flotation for the enhanced treatment of bio-treated drilling wastewater from a gas field.

Working fluid preparation using treated drilling wastewater is of great potential for drilling wastewater reuse, especially in water-deficient and ecologically fragile areas, which require low levels of organic matter and suspended solids (SS). This study established the dissolved ozone flotation (DOF) process as the advanced treatment process to replace the original electrocatalytic system (ECS) which exhibited low organic and suspended solids removal efficiency. Higher and more stable organic matter, suspended solids and turbidity removal efficiency were obtained for the DOF process.

Behaviour of ozone in the hybrid ozonation-coagulation (HOC) process for ibuprofen removal: Reaction selectivity and effects on coagulant hydrolysis.

Simultaneous ozonation and coagulation can be realized in one unit in the developed hybrid ozonation-coagulation (HOC) process. To reveal the reaction sequence within the HOC process, the ibuprofen (IBP) removal efficiency of the ozonation only, HOC and HOC-PO (inhibition of the reactions between ozone and metal coagulant) processes at pH 5 and different ozone dosages were investigated. The removal efficiency is almost the same for the three processes at a low ozone dosage (4.

Enhanced complexation of humic acids: Homogenization of protonated groups in the hybrid ozonation-coagulation process.

In this study, we compared dissolved organic carbon (DOC) and UV removal efficiencies of the hybrid ozonation-coagulation (HOC) and pre-ozonation-coagulation (POC) processes for humic acid (HA) at pH 5 with AlCl•6HO as the coagulant. The DOC and UV removal efficiencies of the HOC process were higher than those of the POC process at ozone dosages less than 2.0 mg O (mg DOC).

Learning Collaborative Sparse Representation for Grayscale-Thermal Tracking.

Integrating multiple different yet complementary feature representations has been proved to be an effective way for boosting tracking performance. This paper investigates how to perform robust object tracking in challenging scenarios by adaptively incorporating information from grayscale and thermal videos, and proposes a novel collaborative algorithm for online tracking. In particular, an adaptive fusion scheme is proposed based on collaborative sparse representation in Bayesian filtering framework.

Paternal cytoplasmic transmission in Chinese pine (Pinus tabulaeformis).

In this paper, the stages of normal sexual reproduction between pollen tube penetration of the archegonium and early embryo formation in Pinus tabulaeformis are described, emphasizing the transmission of parental cytoplasm, especially the DNA-containing organelles--plastids and mitochondria. The pollen tube growing in the nucellus contained an irregular tube nucleus followed by a pair of sperm cells. The tube cytoplasm contained abundant organelles, including starch-containing plastids and mitochondria.
