Are You Going to Use Finasteride for Hair Loss? Read This First

Sold in the market under the brand names Propecia and Proscar, finasteride is a medication that is intended to treat people who are suffering from hair loss.  In the early days, finasteride was just like other medications that were originally used to treat benign prostatic hypertrophy and prostate cancer. It turns out that patients who took finasteride for their prostate-related issues had experienced great results with it, along with a surprising bonus, and that is, the growth of hair.

Finasteride actually works by means of inhibiting or stopping type II 5-alpha reductase, the enzyme responsible for converting the hormone testosterone into dihydrotestosterone (DHT).  DHT, in turn, is the one responsible for losing one’s hair, resulting to baldness if not remedied.  Thus, simply put, the action of finasteride is to prevent the conversion of testosterone into DHT, and the end result would be the prevention of hair loss. This “favorable side effect” of preventing hair loss and promoting growth of new hair by finasteride is what made it famous in the pharmaceutical world, not by its primary use which is for treating benign prostatic hypertrophy and other prostate-related ailments.

Listening in to brain chatter


A microchip will soon be wedded to human neurons

It looks like Canadian researchers are at the threshold of a scientific breakthrough that may pave the way to better meds and superior control of artificial limbs.

Dr. Naweed Syed, a neurobiologist at the University of Calgary, was part of the team that wowed the international scientific world six years ago by successfully fusing mollusc brain cells (in this case pond snails) with a one-millimeter square silicon chip. Now he’s at it again. Dr. Syed, who heads cell biology and anatomy at the U of C, intends to marry human neurons this time around – taken from the brain tissue of a patient undergoing surgery for epilepsy – with the silicon-polymer chip (Biomedical Microdevices).

This will be another step towards being able to not only “listen in on conversations” between synaptic connections as well as ion channels but may lead to more accurate use of drugs. “It means we can track subtle changes in brain activity at the level of ion channels and synaptic potentials, which are also the most suitable target sites for drug development in neurodegenerative diseases and neuropsychological disorders,” says Dr. Syed, who works out of a lab at the U of C's Hotchkiss Brain Institute. The research is also being supported by the National Research Council.

The prototype biochip in its new, more refined state will record messages of excitation and inhibition between neurons. It will also allow for communication between computers and itself. This could mean that future hybrid chips might operate protheses, help improve sight or language after a stroke, and repair malfunctioning neurons for those with Parkinson’s and Alzheimer’s disease.

The current chip is automated, making its use quick and easy, unlike the previous version, but 750 reuseable chips currently cost $300,000 – a definite deterrent for anyone planning to use them to build an Bionic Man.

Seriously..... where is Sam?

We do not need essays for presentation based on perusal/reiteration of common news.

We need " behind-the-scenes " reporting of reactions, and "fleshing out" how we got to/get to from "here" to "there"

Let's have an investigation into the CMA perspective on a prescription-free zone... what birthed that? where is it going?

How about tracing the habituation features of the H1N1 WHO announcement and how the new ' superbug' from ?India will be handled.

Environmental analysis anyone?

Operational reviews are for pathologists.

I found this article fascinating. Have been perusing this blog for a couple of days now, and appreciate every tidbit it can give me about Canadian medicine. (Does anyone else find the comment style by "Sharon" somewhat irritating?)
