In terms of clinical outcome there was little difference between the treatment groups. Thus, with the higher cost of the kyphotic balloon procedure, we recommend vertebroplasty over kyphoplasty for the treatment of osteoporotic VCFs.
We explored whether substance P (SP) via neurokinin (NK) receptor facilitates bladder afferent signaling and reactive oxygen species (ROS) formation in bladder in association with neurogenic inflammation. We evaluated ROS activity and cystometrograms as well as pelvic nervous activity in anesthetized rat bladder with SP stimulation. Our results showed that endogenous SP via NK(1), not NK(2), receptor mediated a micturition reflex. An increase in SP by electrical stimulation of the pelvic nerve or an increase in exogenous SP by intra-arterial or intrathecal administration can facilitate myogenic and neurogenic bladder contractions. Furthermore, exaggerated SP release increased ROS in the bladder and whole blood via increased mast cell degranulation, intercellular adhesion molecule expression, and leukocyte adhesion, a primary source of ROS in the inflamed bladder. Treatment with NK(1)-receptor antagonists or ROS scavengers reduced bladder intercellular adhesion molecule expression and ROS and ameliorated the hyperactive bladder response. Our study indicates that the mechanism by which SP participates in the neurogenic bladder may be complicated by its proinflammatory activity and its ability to stimulate ROS generation.
Our study indicates that DCP has a better diagnostic value than AFP in differentiating HCC from nonmalignant chronic liver disease. DCP has not only a stronger correlation with HCC than AFP in tumor size but also more effectiveness than AFP in detecting small size of HCC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
