research GABAergic neurosteroids mediate the effects of ethanol on long‐term potentiation in rat hippocampal slices

48 citations , September 2007 in “European Journal of Neuroscience”

This study found that ethanol's ability to block long-term potentiation in rat hippocampal slices is influenced by neurosteroids that enhance GABA A receptor activity.

research Neo-synthesis of estrogenic or androgenic neurosteroids determine whether long-term potentiation or depression is induced in hippocampus of male rat

32 citations , October 2015 in “Frontiers in Cellular Neuroscience”

This study found that in male rat hippocampal slices, DHT is necessary for low frequency stimulation-induced long-term depression, while E2 synthesis is essential for high frequency stimulation-induced long-term potentiation.

Synaptic Long-Term Potentiation and Depression in the Rat Medial Vestibular Nuclei Depend on Neural Activation of Estrogenic and Androgenic Signals

research Synaptic Long-Term Potentiation and Depression in the Rat Medial Vestibular Nuclei Depend on Neural Activation of Estrogenic and Androgenic Signals

25 citations , November 2013 in “PLoS ONE”

This study demonstrates that locally synthesized estrogen and androgen neurosteroids play opposite roles in long-term synaptic changes in male rats' medial vestibular nucleus, with testosterone-dihydrotestosterone mediating long-term depression and 17β-estradiol mediating long-term potentiation.

Bisphenol-A Antagonizes the Rapidly Modulating Effect of Dihydrotestosterone on Spinogenesis and Long-Term Potentiation of Hippocampal Neurons

research Bisphenol-A antagonizes the rapidly modulating effect of DHT on spinogenesis and long-term potentiation of hippocampal neurons

10 citations , December 2017 in “Chemosphere”

In this study, BPA rapidly increased dendritic spine and synapse densities in cultured rat hippocampal neurons, with involvement of estrogen receptors and ERK1/2 and p38 pathways, but disrupted dihydrotestosterone's effects on synaptic plasticity.

research Locally Synthetized 17-β-Estradiol Reverses Amyloid-β-42-Induced Hippocampal Long-Term Potentiation Deficits

January 2024 in “International journal of molecular sciences”

This study found that boosting the synthesis of neural-derived 17β-estradiol effectively counteracted the impairment of hippocampal long-term potentiation caused by amyloid beta 1-42 in rat hippocampal slices, with the effect seemingly linked to glutamate NMDAR signaling.

community 4 months on dutasteride and 6 on oral minox. After being on fin and topical minox for 2+ years

in Is this regrowth? 123 upvotes 1 year ago

The user experienced significant hair regrowth after switching to oral minoxidil and dutasteride, having previously used finasteride and topical minoxidil. They reported no side effects from the current regimen of 0.5 mg dutasteride and 5 mg oral minoxidil.

community 57% increased chance of pattern hair loss independently associated with the consumption of sugary beverages in men (p<0.001).

297 upvotes 2 years ago

Sugary beverages increase the risk of pattern hair loss in men by 57%, and type 2 diabetes is linked to female pattern hair loss. Reducing sugar intake and using treatments like finasteride and minoxidil may help manage hair loss.

community Finasteride and “anti-aging” effects

in Treatment 218 upvotes 1 year ago

Finasteride may help users look younger by suppressing DHT, affecting skin and hair. Users also emphasize skincare, sunscreen, and lifestyle for maintaining a youthful appearance.

community DHT is NOT very important for adults, is it?

124 upvotes 4 months ago

A user experienced negative side effects, including low libido and lack of motivation, after using finasteride for hair loss and felt better after stopping it. Others shared similar experiences with finasteride and dutasteride, while some reported no side effects, showing varied individual responses.

community 57% increased chance of pattern hair loss independently associated with the consumption of sugary beverages in men (p<0.001) Pt 2

484 upvotes 2 years ago

Sugary beverages increase the risk of pattern hair loss in men by 57%. Treatments discussed include Minoxidil, finasteride, and RU58841.

learn Fluocinolone

Can long-term use of Fluocinolone affect the health of hair follicles? There is no long-term human trial measuring what topical fluocinolone does to hair follicles; what is documented is the label's warning about skin atrophy with prolonged use, plus a 2007 mouse study suggesting hair-follicle bulge stem cells do not repair steroid-induced atrophy.

learn Hydrocortisone

What are the risks of long-term hydrocortisone use on the scalp? Dermatology reviews describe long-term topical corticosteroid use as causing skin thinning, delayed healing, greater infection risk, possible suppression of the body's own cortisol, and rebound flares on stopping — and over-the-counter hydrocortisone labels limit use to about a week without a doctor's direction.

learn Osteopontin

Is Osteopontin safe to use long-term in hair growth products? Osteopontin's long-term safety in hair growth products is not yet established.

learn Rapamycin

Is rapamycin safe for long-term use on the scalp, or should it be used in cycles? There is no published human trial of topical rapamycin on the scalp, so nobody knows whether long-term use is safe; the idea of cycling it comes from community practice and theory, not from any study or guideline, and rapamycin for hair loss is an off-label use of a prescription immunosuppressant.

learn Azelaic Acid

Is azelaic acid safe to use daily long-term? Azelaic acid has a long tolerability record on facial skin in acne and rosacea, where side effects are local and usually mild — but for daily long-term scalp use the only trial is one six-month study in 26 women, in which mild itching was the main adverse effect, so long-term scalp safety is not established.
