Washing, Drying, and Ignition of Precipitates00:52

Washing, Drying, and Ignition of Precipitates

6.7K
After filtration, the precipitate is washed to remove coprecipitated impurities and any remaining mother liquor. Colloidal precipitates, such as silver chloride, are washed with an electrolyte (such as dilute nitric acid) to prevent the peptization of the precipitate. In the case of slightly soluble precipitates, the wash solution contains a common ion to reduce solubility. Lead sulfate, which is slightly soluble in water, is washed with dilute sulfuric acid. Similarly, wash solutions may be...

Energy-releasing Steps of Glycolysis01:28

Energy-releasing Steps of Glycolysis

146.7K
Glycolysis is divided into two phases based on whether energy is utilized or released. While the first phase consumes ATP, the second phase produces energy in the form of ATP and NADH. The energy is released over a sequence of reactions that turns G3P into pyruvate. The energy-releasing phase—steps 6-10 of glycolysis—occurs twice, once for each of the two 3-carbon sugars produced during steps 1-5 of the first phase.
The first energy-releasing step—the 6th step of glycolysis...

Drugs Affecting Neurotransmitter Release or Uptake01:21

Drugs Affecting Neurotransmitter Release or Uptake

1.6K
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...

ATP Energy Storage and Release01:31

ATP Energy Storage and Release

14.3K
ATP is a highly unstable molecule. Unless quickly used to perform work, ATP spontaneously dissociates into ADP and inorganic phosphate (Pi), and the free energy released during this process is lost as heat. The energy released by ATP hydrolysis is used to perform work inside the cell and depends on a strategy called energy coupling. Cells couple the exergonic reaction of ATP hydrolysis with endergonic reactions, allowing them to proceed.
One example of energy coupling using ATP involves a...

In Vitro Drug Release Testing: Overview, Development and Validation

327
In vitro dissolution and drug release tests assess how quickly and how much of a drug is released from its dosage form into an aqueous medium under standardized laboratory conditions. These tests are essential tools in pharmaceutical development and quality assurance, offering insight into the drug's performance before clinical use.During formulation development, dissolution testing identifies incomplete or inconsistent drug release issues. It also supports decisions on selecting the optimal...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein01:20

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

886
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Area of Science:

  • Environmental Science
  • Materials Science

Background:

  • Microfibers, a subset of microplastics, are prevalent in aquatic ecosystems, particularly in municipal wastewater.
  • Synthetic textiles are major contributors to microfiber pollution.

Purpose of the Study:

  • To quantify microfiber shedding from polyester, polyamide, and acetate fabrics during laundry.
  • To investigate factors influencing microfiber release, including washing machine type, temperature, and detergent presence.

Main Methods:

  • Washing three common synthetic textile fabrics (polyester, polyamide, acetate) in pulsator and platen laundry machines.
  • Quantifying microfiber release per square meter per wash.
  • Analyzing the effect of washing temperature and detergent on microfiber shedding.

Main Results:

  • Acetate fabrics exhibited the highest microfiber shedding (up to 74,816 ± 10,656 fibers/m² per wash).
  • Microfiber release increased with higher washing temperatures and when detergent was used.
  • Pulsator machines' lint filters captured longer microfibers (>1000 μm) but not shorter ones (<500 μm).

Conclusions:

  • Laundry of synthetic textiles is a significant source of aquatic microfiber pollution.
  • Developing more effective filtering technologies for washing machines is crucial to mitigate microfiber release.
