Substantial CO uptake by biomass ashes under natural condition in China.

A considerable amount of biomass ashes, resulting from agricultural waste field burning, wildfire, and solid biofuel incineration, is typically discarded in field or stored in dumps, where the alkaline oxides (CaO, MgO) they contain undergo carbonation and weathering-erosion processes over extended periods, continuously absorbing CO from the atmosphere and soil. However, their CO absorption behavior under natural conditions remains insufficiently explored in China. Using life cycle assessment (LCA) and material flow analysis (MFA) methods, this study developed a CO absorption analysis model for biomass ashes under natural conditions.

Meta-analysis of the efficacy and safety of integrated Chinese and Western medicine in the treatment of acute myeloid leukaemia in elderly people.

Objective: To systematically evaluate the effectiveness and safety of integrated Chinese and Western medicine in the treatment of acute myeloid leukaemia (AML) in elderly people.

Method: The Cochrane Library, PubMed, Web of Science, Excerpta Medica Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Wanfang Data and VIP Data databases were systematically searched from database inception to 30 June 2023 to identify cases of AML treatment with and without integrated Chinese and Western medicine. Fixed- and random-effect models were used to pool the main results, and the pooled risk ratio (RR) with a 95 % confidence interval (CI) was used as the effect indicator.

[Corrigendum] Exogenous hydrogen sulfide exerts proliferation, anti-apoptosis, migration effects and accelerates cell cycle progression in multiple myeloma cells via activating the Akt pathway.

Following the publication of this article, an interested reader drew to the authors' attention that, in Fig. 4 on p. 1913, the t-Akt panel in Fig.

The value of virtual touch tissue imaging quantification in the differential diagnosis between benign and malignant breast lesions.

Purpose: To evaluate the value and diagnostic performance of virtual touch tissue imaging quantification (VTIQ) and to determine the optimum cut-off value for differential diagnosis between benign and malignant breast lesions.

Methods: Conventional ultrasonography (US) and VTIQ were performed in 454 patients with 466 breast lesions with a Siemens Acuson S3000 ultrasound machine. All lesions were assessed by an ultrasound Breast Imaging Reporting and Data System (BI-RADS) and confirmed by histopathology.

Exogenous hydrogen sulfide exerts proliferation, anti-apoptosis, migration effects and accelerates cell cycle progression in multiple myeloma cells via activating the Akt pathway.

Hydrogen sulfide (H2S), regarded as the third gaseous transmitter, mediates and induces various biological effects. The present study investigated the effects of H2S on multiple myeloma cell progression via amplifying the activation of Akt pathway in multiple myeloma cells. The level of H2S produced in multiple myeloma (MM) patients and healthy subjects was measured using enzyme-linked immunosorbent assay (ELISA).
