TLDR Neurotrophins, especially NGF, are crucial for pain development and management.

The document reviewed the role of neurotrophins, particularly nerve growth factor (NGF), in the development and function of nociceptors and nociception. It highlighted that NGF is crucial for the survival and phenotype expression of nociceptors during prenatal and early postnatal development. In adults, NGF was found to be significant in inflammatory pain, contributing to peripheral and central sensitization. The study discussed the use of transgenic mice and NGF administration to manipulate NGF levels. It also noted that other neurotrophins, such as NT-3, BDNF, and NT-4/5, and molecules from other superfamilies like GDNF, play essential roles in nociceptor development and inflammatory pain. The findings underscored the broad importance of neurotrophins in nervous system development and function.

community The theory that explains everything. Please help me make this big!

in Research/Science 2447 upvotes 3 years ago

The post and conversation are about the role of the enzyme 3alpha-hydroxysteroid reductase in hair loss and the potential of compounds like procyanidin B2 and sulforaphane to boost its activity for hair regrowth. Further research is needed to develop effective treatments based on this theory.

community Treatment of Finasteride Induced Gynecomastia (Male breast tissue growth)

in Finasteride/Dutasteride 15 upvotes 4 years ago

Finasteride can cause gynecomastia, which may be reversible by stopping the drug and using selective estrogen receptor modulators (SERMs) like tamoxifen. Lifestyle changes such as weight loss and avoiding alcohol can also help, but surgery may be needed if the condition persists.

community Please explain this Minoxidil phenomena

in Minoxidil 56 upvotes 1 year ago

The post discusses the difference in effects of Minoxidil (Min) on scalp and facial hair. The user questions why Min-induced hair growth on the scalp is temporary, while facial hair growth seems permanent, even after stopping Min. They propose theories, including different Min mechanisms on body and facial hair, the role of DHT, and the possibility of not achieving fully terminal hair. The responses include personal experiences and theories about Min's effects on hair growth.

A hair loss treatment plan includes finasteride, dutasteride, RU58841, pyrilutamide, minoxidil, and microneedling to inhibit DHT and promote hair growth. It also recommends supplements like Reishi and Lion’s Mane mushrooms, and a shampoo with ketoconazole, caffeine, and melatonin.

community Impressed by the progress but think it’s time to go for the transplant?

in Progress Pictures 288 upvotes 10 months ago

The user started taking 2.5mg minoxidil tablets daily and reduced their finasteride dose to 0.5mg due to side effects. They are considering a hair transplant but are unsure if they should proceed now or wait after seeing the effects of the reduced finasteride dosage.

community Table of the relationship between physical exercise and the regeneration of the deminiaturized hair follicle

in Research/Science 45 upvotes 2 months ago

Exercise, especially leg workouts, combined with finasteride and minoxidil, may enhance hair regrowth. Cold exposure, like cold showers, might further boost results.
