Deleterious Substances in Aggregate

Deleterious Substances in Aggregate

Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.
Another type of impurity is clay and fine material that...

Spreading of Chromatin Modifications

Spreading of Chromatin Modifications

The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Depolarizing Blockers: Pharmocokinetics

Depolarizing Blockers: Pharmocokinetics

Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...

Depolarizing Blockers: Mechanism of Action

Depolarizing Blockers: Mechanism of Action

Depolarizing blockers act on skeletal muscle fibers' membranes and induce their depolarization. Most depolarizing blockers have two quaternary N+ atoms that bind the nicotinic acetylcholine receptors and cause neuromuscular blockade within minutes.
Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because...

Tissues

Tissues

Cells with similar structure and function are grouped into tissues. A group of tissues with a specialized function is called an organ. There are four main types of tissue in vertebrates: epithelial, connective, muscle, and nervous.

Tissues

Tissues

Tissues are a group of cells that share a common embryonic origin. Microscopic observation reveals that the cells in a tissue share morphological features and are arranged in an orderly pattern to perform specific functions. From an evolutionary perspective, tissues appear in more complex organisms. Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. Each of these categories is...

Area of Science:

Neuroscience
Pathophysiology
Critical Care Medicine

Background:

Spreading depolarizations (SDs) disrupt cellular homeostasis and pose metabolic challenges to brain tissue.
SDs are frequently observed in neurocritical care patients and are implicated in acute brain injury pathophysiology.
The International Conference on Spreading Depolarizations (iCSD) convened to discuss the detrimental effects of SDs on brain tissue.

Purpose of the Study:

To address the question of which types of spreading depolarizations (SDs) are deleterious to brain tissue.
To synthesize expert opinions from a multidisciplinary group of researchers studying SDs.
To identify areas of agreement and divergence regarding SDs to inform clinical intervention strategies.

Main Methods:

A discussion session at the iCSD conference focused on the detrimental effects of SDs.
A multidisciplinary writing group drafted a summary of viewpoints based on session transcripts.
Feedback from all discussants was collected, reviewed, and incorporated into the final report.

Main Results:

General agreement was reached on many key issues concerning SDs.
Divergent views were identified on specific topics relevant to designing clinical interventions targeting SDs.
The report consolidates diverse perspectives on the pathophysiology and clinical relevance of SDs.

Conclusions:

Further data collection is needed for a nuanced understanding of SDs in various pathophysiological states.
This report aims to stimulate research toward developing effective clinical interventions for SDs.
Clarifying the role of different SDs in brain injury is crucial for advancing therapeutic strategies.
