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

Pest 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.

Complement peptide C3a promotes astrocyte survival in response to ischemia

, 2016
Astrocytes are the most numerous cells in the central nervous system with a range of homeostatic and regulatory functions. Under normal conditions as well as after ischemia, astrocytes promote neuronal survival.

Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

Structural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

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

Structural 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 ...

Acidosis activates complement system in vitro

Mediators of Inflammation, 1998
We investigated the in vitro effect of different form s of acidosis (pH 7.0) on the formation of anaphylatoxins C3a and C5a. Metabolic acidosis due to addition of hydrochloric acid (10 μ mol/ml blood) or lactic acid (5.5 μ mol/ml) to heparin blood (N=12)

Activation of complement by hemodialysis membranes: Polyacrylonitrile binds more C3a than cuprophan [PDF]

, 1990
Activation of complement by hemodialysis membranes: Polyacrylonitrile binds more C3a than cuprophan. Conventionally, complement activation by hemodialysis membranes has been determined by measuring fluid phase C3a.

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

SusMat, 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
