A label-free-based fiber optic biosensor based on etched tilted Bragg grating (TFBG) is proposed and practically demonstrated. Conventional phase mask technic has been utilized to inscribe with a tilt angle of 10°, while the etching accomplished hydrofluoric acid. composite polyethylenimine (PEI)/poly(acrylic acid) (PAA) thermally deposited TFBG, followed by immobilization probe DNA (pDNA) this...

objective(s): hypoxia is a serious challenge for treatment of solid tumors. this condition has been manifested to exert significant therapeutic effects on glioblastoma multiform or (who) astrocytoma grade iv. hypoxia contributes numerous changes in cellular mechanisms such as angiogenesis, metastasis and apoptosis evasion. furthermore, in molecular level, hypoxia can cause induction of dna brea...

pigeonpea (cajanus cajan (l) millsp.) is a drought tolerant legume widely grown in the arid and semi-arid tropics of the world which possesses a deep and extensive root system that succors a number of important physiological and metabolic functions to cope with drought. application of available functional genomics approaches to improve productivity under water deficit requires a better understa...

background: cholera is a potentially epidemic and life-threatening secretory diarrhoea characterized by voluminous watery stools, often accompanied by vomiting, and resulting in hypovolemic shock and acidosis. it is caused by certain strains of the species vibrio cholerae which can also cause mild or in apparent infections. the aim of this study is the evaluation of capsaicin, as a potential in...
