Because it works locally on the scalp, topical finasteride keeps systemic exposure very low, reducing the chance of side effects while maintaining effectiveness
This is important as time free of symptoms is one the most desired factors by both patients and prescribers
Recall from Equation 16.23 that the p K b of a weak base and the p K a of its conjugate acid are related: p K a + p K b = p K w
Their exceptional chemical stability allows environmental persistence exceeding two decades, leading to progressive bioaccumulation through food webs and preferential storage in lipid-rich tissues ( Human exposure to these compounds occurs through multiple pathwaysingestion, inhalation, and dermal absorptionwith subsequent accumulation in adipose tissue, hepatic systems, and critically, reproductive organs ( 1.2 Key research challenges Despite substantial advances in understanding individual EED toxicity profiles, several fundamental knowledge gaps continue to impede comprehensive risk assessment: Complex Mixture Effects Remain Poorly Understood While toxicological studies have extensively characterized individual EED effects, real-world human exposure invariably involves simultaneous contact with multiple compounds
Primary antibodies were then applied: mouse anti-OPA1 (1:200, BD Biosciences, 612606) and rabbit anti-DRP1 (1:200, Abcam, AB184247) and incubated at 37 C for 23 h
