Social Traps01:41

Social Traps

26.9K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Open Angle Glaucoma: Treatment

990
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Treatment Resistant Cancers

3.7K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Parkinson's Disease: Treatment

1.1K
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Alzheimer's Disease: Treatment

914
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Anticholinesterase Agents: Poisoning and Treatment01:26

Anticholinesterase Agents: Poisoning and Treatment

1.6K
Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.     
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Pathology

Background:

  • Excessive enzyme activity, particularly of serine proteases in the coagulation and kallikrein-kinin systems, underlies pathological conditions such as thrombosis and hereditary angioedema.
  • Serine protease inhibitors (SERPINs) are crucial regulators of these enzyme activities.

Purpose of the Study:

  • To elucidate the fundamental biochemical mechanisms governing SERPIN activity.
  • To identify key factors influencing SERPIN function.
  • To explore clinical implications of SERPIN deficiencies and novel therapeutic applications.

Main Methods:

  • Biochemical analysis of SERPIN mechanisms.
  • Identification of determinants of SERPIN function.
  • Review of clinical phenotypes associated with SERPIN deficiencies.
  • Exploration of SERPINs in therapeutic strategies beyond simple replacement.

Main Results:

  • Detailed description of basic biochemical mechanisms of SERPIN activity.
  • Identification of key determinants influencing SERPIN function.
  • Exploration of clinical phenotypes in SERPIN deficiencies.
  • Review of SERPINs utilized in therapeutic contexts beyond replacement therapy.

Conclusions:

  • Understanding SERPINs' biochemical mechanisms and functional determinants is essential for comprehending their role in pathology.
  • Rare human SERPIN mutations offer insights into refining these inhibitors for therapeutic purposes.
