Senescence is a well-known cellular event characterized by specific markers like permanent cell proliferation arrest and the secretion of messenger molecules forming Senescence-Associated Secretory Phenotype (SASP). The SASP composition depends on many factors such as type nature stress that induced senescence. Since skin constitutes barrier with external environment, it particularly subjected ...

CONTEXT Cholinesterase (ChE) specific activity is the ratio of ChE activity to ChE mass and, as a biomarker of exposure to cholinesterase inhibitors, has a potential advantage over simple ChE activity. OBJECTIVE To examine the association of several potential correlates (serum arylesterase/paraoxonase activity, serum albumin, sex, age, month of blood collection, and smoking) with plasma ChE s...
