Dutasteride
Dutasteride inhibits type I and II 5-α-reductase, achieving deeper DHT suppression than finasteride. Trials report greater increases in hair counts and cosmetic improvement, particularly in advanced thinning. It is a high-potency pharmacologic option used when maximal DHT control is prioritized.

Dual isoenzyme inhibition (types I/II) serum DHT suppression often (90%). Type I 5-AR expression in scalp/sebaceous glands adds theoretical advantage for vertex and frontal preservation.
Head-to-head and dose-ranging studies demonstrate superior efficacy vs. finasteride on hair counts and investigator assessments. Benefits accrue through 6–12 months with continued gains thereafter.
Often used after inadequate response to finasteride. Stack with minoxidil; keep ketoconazole as adjunct for scalp environment. Consider medical supervision given depth of systemic DHT reduction.

Comparison of 2.6- and 1.4-mm imaging probes for confocal laser endomicroscopy of the urinary tract - PubMed
The optical specifications of the 2.6-mm probe are more suitable for distinguishing urinary tract histopathology. Further design optimization to improve resolution and additional validation of the diagnostic accuracy of the smaller probe are needed to help extend application of pCLE for optical...


Successful amplification of extremely GC-rich promoter regions using a novel 'slowdown PCR' technique - PubMed
Here we show that 'Slowdown' PCR is a versatile method not only for amplification of extremely GC-rich regions but also for routine DNA diagnostics and pharmacogenetics for templates with different annealing temperatures.
