City-Level Sugar-Sweetened Beverage Taxes and Changes in Adult Body Mass Index.

Importance: Sugar-sweetened beverage (SSB) excise taxes are popular policy interventions aimed at decreasing SSB purchasing and consumption to improve cardiometabolic health and generate revenue for public health initiatives. There is limited evidence that these taxes in the US are associated with weight-related outcomes in adults, a primary contributor to cardiometabolic health.

Objective: To determine the association between SSB excise taxes and adult body mass index (BMI) and proportion of adults with overweight or obesity among California cities and assess whether associations vary by demographic characteristics.

Tracing Aquatic Macrophyte Development in Nansi Lake, Northern China's Largest Freshwater Lake: Plant Macrofossils From 1855 to Present.

Examining the impacts of natural and anthropogenic influences on aquatic macrophytes in shallow lakes is crucial for their effective restoration and management. However, there is a lack of direct evidence regarding past species composition or detailed and continuous evidence of recent changes in aquatic macrophyte communities. This study utilized plant macrofossil remains deposited in the sediment, combined with macrophyte surveys from 1983 to 2010, to reconstruct the historical changes in the macrophyte community over approximately 160 years in Lake Weishan, a sub-lake of Lake Nansi located in the lower Yellow River (Huanghe River) Basin, northern China.

Targeted internalization and activation of glycosidic switch liposomes by a biological macromolecule mPEG×EphA2 increases therapeutic efficacy against lung cancer.

Glycosidic switch liposome (GSL) technology efficiently encapsulates and stabilizes potent anticancer drugs in liposomes using a reversible glucuronide ester. Enzymatic hydrolysis of the glucuronide switch in target cell lysosomes produces parental drug. Our study examined the potential of a bispecific macromolecule, a polyethylene glycol (PEG) engager (mPEG×EphA2), generated by fusing a humanized anti-methoxy PEG (mPEG) Fab with an anti-EphA2 single-chain antibody, to increase GSL uptake into cancer cells and boost the anticancer activity by targeting PEG on GSL and an internalizing tumor antigen.

Dual Ratiometric Fluorescence Sensors Based on Chiral Carbon Dots for the Sensitive and Specific Detection of Arginine.

Arginine (Arg) is involved in tissue metabolism and regulates the immune function; thereby, achieving the detection of Arg is crucial for early diagnosis and treatment of diseases. Herein, dual ratiometric fluorescence sensors were prepared with the blue emission of levorotatory/dextrorotatory carbon dots (CDs) and the red emission of porphyrin (L/D-CDs-PP) for the sensitive and portable detection of Arg. Interestingly, L-CDs-PP and D-CDs-PP displayed not only the dual emission peaks at 493 and 650 nm but also different response modes to Arg; thus, they could serve as dual ratiometric fluorescence sensors to achieve the accurate and reliable detection of Arg, with the detection limit of 23.

Atomic Gap-State Engineering of MoS for Alkaline Water and Seawater Splitting.

Transition-metal dichalcogenides (TMDs), such as molybdenum disulfide (MoS), have emerged as a generation of nonprecious catalysts for the hydrogen evolution reaction (HER), largely due to their theoretical hydrogen adsorption energy close to that of platinum. However, efforts to activate the basal planes of TMDs have primarily centered around strategies such as introducing numerous atomic vacancies, creating vacancy-heteroatom complexes, or applying significant strain, especially for acidic media. These approaches, while potentially effective, present substantial challenges in practical large-scale deployment.
