Soil erosion and sedimentation are among the most serious global environmental *** and water conservation measures have been proven effective ways to reduce soil *** objective of this study was to evaluate the impact of three approaches of soil and water conservation measures(soil management,vegetative measures,and structural practices)on soil erosion and water balance of two paired agricultural watersheds located in Southern *** and sediment monitoring was carried out from 2016 to 2019 in the two small paired agricultural watersheds;called North watershed(NW)and South watershed(SW).Modeling using Soil&Water Assessment Tool(SWAT)was performed to simulate individual(nine scenarios)and combined(four scenarios)best management practices(BMPs),by including the three *** the nine individual BMP scenarios,the most effective in reducing soil erosion was crop rotation and cover crop(sediment yield,SY,reduction of 38.4 for NW,and 28.8%for SW).Among the four combined scenarios,the association of all conservation approaches was the most effective in reducing soil erosion(SY reduction of 46 for NW,and 41.5%for SW),followed by the vegetative measures scenario(SY reduction of 43.5 and 34.1%for NW and SW).All combined scenarios increased infiltration and subsurface water components,and decreased surface *** findings of this study can help farmers and policymakers choosing appropriate BMPs to reduce current soil erosion problems and promote water and soil conservation.

The Use of Insulin Negatively Impacts the Mortality of Severe COVID-19 in Patients with Type 2 Diabetes—A Systematic Review

引用

Journal of Diabetes Mellitus 2024年第3期14卷 166-176页

作者： Caio F. Biolcatti Marcela R. Simoes thais P. Prado Milena Monfort-Pires Licio A. Velloso Obesity and Comorbidities Research Center Campinas Brazil Turku PET Centre University of Turku Turku Finland National Institute of Science and Technology on Neuroimmunomodulation Campinas Brazil

Obesity and type 2 diabetes are among the most important risk factors for severe coronavirus disease-19. Some studies have suggested that the use of insulin as a therapeutic agent to treat hyperglycemia and the metabolic abnormalities associated with type 2 diabetes during the acute phase of severe coronavirus disease-19 could have a negative impact on the disease’s progression;however, there is no consensus on this issue. Here, we performed a systematic review in an attempt to answer this important question. We included 29 articles published from December 2019 to August 2023, which reported the outcomes of 3,070,657 patients with severe coronavirus disease-19 that had the diagnosis of diabetes and were treated with either insulin or other glucose-reducing agents. The results show that using insulin as a pharmacological intervention to treat type 2 diabetes in patients with severe coronavirus disease-19 increases the likelihood of mortality by 193%.

Objective To evaluate the chemical composition and effects of Artemisia vulgaris(AV)hydroalcoholic extract(HEAV)on breast cancer cells(MCF-7 and SKBR-3),chronic myeloid leukemia(K562)and NIH/3T3 *** Phytochemical analysis of HEAV was done by high-performance liquid chromatography-mass(HPLC)*** and cell death studies were performed using trypan blue and Annexin/FITC-7AAD,***-1(Fer-1)and necrostatin-1(Nec-1)were used to assess the mode of HEAV-induced cell death and acetoxymethylester(BAPTA-AM)was used to verify the involvement of cytosolic calcium in this *** calcium measurements were made using *** HEAV decreased the viability of MCF-7,SKBR-3 and K562 cells(P<0.05).The viability of HEAV-treated K562 cells was reduced compared to HEAV-exposed fibroblasts(P<0.05).Treatment of K562 cells with HEAV induced cell death primarily by late apoptosis and necrosis in assays using annexin V-FITC/7-AAD(P<0.05).The use of Nec-1 and Fer-1 increased the viability of K562 cells treated with HEAV relative to cells exposed to HEAV alone(P<0.01).HEAV-induced Ca^(2+)release mainly from lysosomes in K562 cells(P<0.01).Furthermore,BAPTA-AM,an intracellular Ca^(2+)chelator,decreased the number of non-viable cells treated with HEAV(P<0.05).Conclusions HEAV is cytotoxic and activates several modalities of cell death,which are partially dependent on lysosomal release of Ca^(2+).These effects may be related to artemisinin and caffeoylquinic acids,the main compounds identified in HEAV.
