lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

10.0K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Nursing Code of Ethics01:29

Nursing Code of Ethics

4.6K
The Nursing Code of Ethics sets the ethical benchmark for the profession, and guides nurses in ethical analysis and decision making at the societal, organizational, and clinical levels. The code encompasses showing compassion and respect for the patient, their families, and communities in all circumstances while committing to providing patient-centered care. In addition, the code states that nurses must advocate for the patient by defending a cause or recommendation to protect their rights,...

Regulation of Hormone Secretion01:19

Regulation of Hormone Secretion

6.9K
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.

Hormones Secreted by the Stomach01:25

Hormones Secreted by the Stomach

2.8K
Enteroendocrine cells, accounting for only 1% of stomach epithelial cells, play a significant role in digestion and are classified by their digestive hormone secretions.
Each of these hormones secreted by different enteroendocrine cells plays a unique role in digestion. Here are a few examples:

Pancreatic Juice and Secretion01:26

Pancreatic Juice and Secretion

3.1K
Pancreatic juice is a clear fluid produced by the pancreas, containing water, salts, sodium bicarbonate, and enzymes vital for digestion in the small intestine. It helps break down large molecules, facilitating nutrient absorption.
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...

Area of Science:

  • Materials Science
  • Electrical Engineering
  • Nanotechnology

Background:

  • Secure personal identification and data transmission are crucial.
  • Existing methods often require external power sources and lack flexibility.

Purpose of the Study:

  • To develop a self-powered, transparent secret code (TSC) for secure human-machine communication.
  • To enable simultaneous sensing and information identification using a flexible, hydrophobic material.

Main Methods:

  • Fabrication of a triboelectric-based transparent secret code (TSC).
  • Testing the TSC's electrical signal generation upon surface contact and its velocity dependence.
  • Evaluating the TSC's durability through reciprocating rolling tests.

Main Results:

  • The TSC generates obvious electric signals, peaking at ≈4 V with a 10 MΩ load at 0.1 m s-1.
  • The flexible and hydrophobic TSC conforms to cambered surfaces, enabling diverse applications.
  • The device maintained performance after approximately 5000 reciprocating rolling cycles.

Conclusions:

  • The TSC functions as a self-powered code device, converting ordered electric signals into identifiable information.
  • The technology shows significant potential for personal identification, security, and asset management.
