ABSTRACT
Psoriatic arthritis (PsA) is a complicated psoriasis comorbidity with manifestations of psoriatic skin and arthritic joints, and tailoring specific treatment strategies for simultaneously delivering different drugs to different action sites in PsA remains challenging. We developed a need-based layered dissolving microneedle (MN) system loading immunosuppressant tacrolimus (TAC) and anti-inflammatory diclofenac (DIC) in different layers of MNs,
ABSTRACT
Attaining higher peak bone mass and strength in early life stage is critical for reducing risk of osteoporosis or lower bone mass later in life. Genetic factors such as race and gender are mostly responsible for the variability and timing of reaching peak bone mass. In general, Asians have lower areal bone mineral density and would reach peak bone mass earlier when they are compared to Caucasians. Among different lifestyle factors, strong evidence is only available for positive effects of dietary calcium and physical exercise on bone accretion. Studies showed that the calcium intake of Chinese population at all ages is well below the recommended intake levels. To develop peak bone mass and strength to reach their genetic potentials, achieving adequate calcium and vitamin D intake through promoting dietary intake and/or supplementation, are strongly recommended, especially in Chinese adolescents.
ABSTRACT
Nrf2,a key transcriptional factor in regulating endog-enous antioxidant signaling pathway,maintains the redox bal-ance by controlling the expression of a battery of antioxidant en-zymes,phase-Ⅱ detoxification enzymes and phase-Ⅲ transport-ers.Furthermore,Nrf2 regulates inflammation.Recent resear-ches have confirmed that Nrf2 provides a vital physiological role in kidney diseases,activation of Nrf2 enhances the antioxidant and anti-inflammatory ability in cellular and tissue levels,thusalleviates renal injury.Here,this article aims to summarize the protective effect of Nrf2 on various models of kidney impairment and explore the potential of Nrf2 as a therapeutic target to pre-vent kidney diseases.
