Fluorescence switch on-off-on receptor constructed of quinoline allied calix[4]arene for selective recognition of Cu2+ from blood serum and F- from industrial waste water.

A novel PET with ICT based substituted calix[4]arene fluroionophore was synthesized and used for detection of Cu(2+) and F(-) by emission spectra. The detection limit of the synthesized receptor was found to be 4.16 nM for Cu(2+) and 2.

Effects of acetylsalicylic acid on reproductive organs of adolescent male rats.

The effects of acetylsalicylic acid (ASA) at a dose of 800 micrograms/day per rat for 7 days on some androgenic parameters such as organ weights, succinate dehydrogenase, acid phosphatase, fructose, cholesterol and protein of testis, epididymis, vas deferens and accesory glands in adolescent male rats were investigated. The semen characteristics and scanning electron microscopy (SEM) study on sperm morphology of cauda epididymis were also carried out. The results revealed that the treatment manifested a marked effect in altering the metabolism of testis, cauda epididymis, seminal vesicle and vas deferens.
