Compounds Essential to Human Function01:25

Compounds Essential to Human Function

10.1K
The human body is composed of cells that are fundamentally made up of several different molecules. These molecules are essential to carry out all physiological processes in the body and are broadly classified into organic and inorganic based on their chemical structures.
Inorganic Compounds Essential to Human Functioning
Inorganic compounds essential to human functioning include water, salts, acids, and bases. These compounds are inorganic, i.e., they do not have a carbon-hydrogen bond. Water...

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

6.3K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Key Elements for Plant Nutrition

24.2K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Eukaryotic Transcription Activators02:42

Eukaryotic Transcription Activators

12.8K
Transcription activators are proteins that promote the transcription of genes from DNA to RNA. In most cases, these proteins contain two separate domains ‒ a domain that binds to DNA and a domain for activating transcription; however, in some cases, a single domain is responsible for both binding and activation of transcription, as seen in the glucocorticoid receptor and MyoD.
The binding domains are capable of recognizing and interacting with regulatory sequences on the DNA. These...

Water and Mineral Acquisition02:34

Water and Mineral Acquisition

35.6K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

Ligand Binding and Linkage00:49

Ligand Binding and Linkage

5.6K
Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked.  In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence...

Summary
This summary is machine-generated.

Essential tremor is a common progressive disorder affecting adults, with variable severity. While treatments like propranolol and primidone exist, advanced options like VIM nucleus stimulation, radiosurgery, and ultrasound thalamotomy offer effective solutions for severe or drug-resistant cases.

Area of Science:

  • Neurology
  • Neurosurgery

Background:

  • Essential tremor is a common, progressive postural tremor in adults with variable severity.
  • Its pathophysiology is not fully understood, though candidate genes are implicated.
  • Alcohol may offer temporary relief, but its mechanism is unclear.

Purpose of the Study:

  • To review the current understanding and therapeutic landscape of essential tremor.
  • To highlight established and emerging treatment modalities for essential tremor.

Main Methods:

  • Literature review of essential tremor pathophysiology and treatment options.
  • Analysis of first-line, second-line, and advanced therapeutic interventions.
  • Inclusion of neurosurgical and radiosurgical techniques.

Main Results:

  • First-line treatments include propranolol or primidone for symptomatic relief.
  • Second-line treatments have variable efficacy.
  • Neurosurgical VIM nucleus stimulation is effective for pharmacoresistant cases.
  • Radiosurgery and ultrasound thalamotomy are alternative or emerging options.

Conclusions:

  • Essential tremor management ranges from medication to advanced neurosurgical interventions.
  • VIM nucleus stimulation, radiosurgery, and ultrasound thalamotomy represent effective options for refractory essential tremor.
  • Ultrasound thalamotomy shows promise as a novel therapeutic approach.
