Erythropoietin Effect on Complement Activation in Chronic Kidney Disease

open access: yesBiomedicines
The complement system is an important part of innate immunity. Despite its known protective role, the complement system may contribute to increased inflammation and tissue injury in cases where its balanced activation is disrupted.

Statistical Downscaling of Daily Temperature and Precipitation From Regional Climate Models in Complex Mountain Terrain

open access: yesInternational Journal of Climatology, EarlyView.
The study provides insights for post‐processing climate model output in complex terrain, useful for climate change impact models. We compared different bias adjustment and downscaling techniques from quantile delta mapping to simple lapse rates. We developed a new spatial downscaling method based on principal components analysis, which showed superior ...

Novel tetronamides derived from mucobromic acid: synthesis, structural elucidation, DFT calculations and phytotoxic activity

open access: yesPest Management Science, EarlyView.
The acyclic mucobromic acid, activated by (1S)‐(+)‐10‐camphorsulfonic acid, afforded the chiral compound 1b, precursor for aza‐Michael addition/elimination on the butenolide yielding tetronamides 2b‐7b. Their relative SRSR configuration was confirmed by the spectrometric methods, DFT calculation and statistical methods.

The role of complement components (C1q, C3a, MAC) activation in earlyand late-onset preeclampsia and fetal growth restriction

open access: yesАкушерство, гинекология и репродукция
Introduction. Preeclampsia (PE) remains one of the leading causes for maternal and perinatal morbidity and mortality. Placental insufficiency associated with impaired trophoblast invasion, hypoperfusion, and inflammatory endothelial activation is ...

Achieving sustainable and durable concrete using high‐volume SiO2: Engineering properties, environmental and economic benefits

open access: yesStructural Concrete, EarlyView.
Abstract This study explores the potential of high‐volume amorphous silica (SiO2) replacement for ordinary Portland cement (OPC) in concrete to reduce carbon emissions. Amorphous SiO2, such as silica fume (SF) and CO2 mineralization‐produced Si‐rich gel, offers superior properties to concrete but is under‐researched for its use in concrete with high ...

Complement C3a Mobilizes Dental Pulp Stem Cells and Specifically Guides Pulp Fibroblast Recruitment

open access: yes, 2016
International audienceIntroduction: Complement activation is considered as a major mechanism in innate immunity. Although it is mainly involved in initiating inflammation, recent data reported its involvement in other processes such as tissue ...

The Complement C3a And C3a Receptor Pathway Indiabetic Patients With Entamobra Histolytica, Cryptospridium Parvum

open access: yesInternational Journal of Environmental Sciences
Cryptosporidium parvum and Entamoeba histolytica are significant protozoan parasites that adversely impact human health. The infection rate of these parasites among diabetic patients was recorded at 18.33%. However, the mechanisms underlying host-parasite interactions remain poorly understood.

Halting the Progression of Acute Kidney Injury: A Tubular‐Inspired Reusable Detoxifier Against Protein‐Bound Uremic Toxins and Oxidative Stress

open access: yesSusMat, EarlyView.
This graphical ToC illustrates a tubular‐inspired detoxifier (SDCMs–DS) that halts acute kidney injury progression. Inspired by proximal tubular epithelial cells (PTECs), the biomimetic design combines dissociation‐adsorption clearance of protein‐bound uremic toxins (PBUTs) with antioxidant protection. During hemoperfusion, danshensu (DS) released from
