Subviral Agents01:29

Subviral Agents

585
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Air-entraining Agents01:27

Air-entraining Agents

276
Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

Masking and Demasking Agents

3.7K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

Spasmolytic Agents: Chemical Classification01:29

Spasmolytic Agents: Chemical Classification

1.3K
Spasmolytic agents are drugs used to alleviate muscle spasms and spasticity. They can be categorized into different chemical groups based on their mechanisms of action. Centrally acting spasmolytics primarily affect the spinal cord, while others directly target skeletal muscle cells.
A major class of centrally acting spasmolytics is the α2-agonist, such as tizanidine. These drugs bind to α2-adrenoceptors, inhibiting the release of the excitatory neurotransmitter glutamate. They also...

Oral Hypoglycemic Agents: Glinides01:06

Oral Hypoglycemic Agents: Glinides

687
Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively...

Oral Hypoglycemic Agents: Sulfonylureas01:17

Oral Hypoglycemic Agents: Sulfonylureas

1.2K
Sulfonylureas are oral hypoglycemic agents utilized in treating type 2 diabetes. They are characterized by their unique sulfonylurea chemical structure. The family of sulfonylureas is divided into generations. First-generation sulfonylureas, including tolbutamide (Orinase), chlorpropamide (Diabinese), and tolazamide (Tolinase), trigger insulin release from pancreatic β cells and enhance peripheral tissues' insulin sensitivity. The second-generation members, such as glipizide...

Summary
This summary is machine-generated.

Cancer treatments can cause infertility. Semen cryopreservation before therapy is the only proven fertility preservation for male patients, but effective methods for prepubertal boys are lacking.

Area of Science:

  • Oncology
  • Reproductive Medicine
  • Genetics

Background:

  • Cancer survival rates have improved, increasing focus on long-term treatment complications.
  • Chemotherapy often causes gonadotoxicity, leading to sterility in cancer survivors.
  • Gonadal dysfunction is drug-specific and dose-dependent.

Purpose of the Study:

  • To review the impact of chemotherapy on male fertility.
  • To discuss current fertility preservation options for cancer patients.
  • To highlight the need for improved strategies, especially for prepubertal patients.

Main Methods:

  • Literature review of studies on chemotherapy, gonadotoxicity, and fertility preservation.
  • Analysis of current assisted reproductive techniques and their efficacy.
  • Examination of existing methods for gonadal protection.

Main Results:

  • Sperm can be retrieved post-treatment in many cases, with assisted reproductive techniques aiding conception.
  • Anticancer agents can induce permanent azoospermia.
  • Cryopreservation of semen is the only established method for male fertility preservation.
  • No effective methods currently protect gonadal function in prepubertal cancer patients undergoing treatment.

Conclusions:

  • Semen cryopreservation before chemotherapy is crucial for male cancer patients.
  • Further research is needed to develop methods for protecting gonadal function in prepubertal boys.
  • Advances in chemotherapy necessitate parallel advancements in fertility preservation strategies.
