1. Though nitrogen exhibits +5 oxidation state, it does not form pentahalide. Give reason. Ans: Nitrogen valence electronic configuration nsnp due to absence empty dorbitals, it can not extend its valence to 5 2. PH3 has lower boiling point than NH3. Why? Ans: Unlike NH3, PH3 molecules are not associated through hydrogen bonding in liquid state. That is why the boiling point of PH3 is lower tha...

OBJECTIVE The aging nose presents as a drooping nasal tip secondary to atrophy of the underlying bony support with a relatively prominent dorsal hump. We hypothesized that low nasal tip projection in the Asian nose may be secondary to the retropositioned anterior nasal spine (ANS) as well. Therefore, we investigated how filler injection between the medial crura and the retropositioned ANS affec...

A specialized taxonomy of the autonomic nervous system (ANS) has been developing since the time of Galen (ad 130200). In the early 1900s, Langley first referred to the ANS. He used the term sympathetic nervous system (SNS) as described by Willis in 1665, and introduced the second division as the parasympathetic nervous system (PNS) in 1921. Although Langely initially described only the visceral...

BACKGROUND There has been increased interest in one-step cell-free procedures to avoid the problems related to cell manipulation and its inherent disadvantages. We have studied the chondrogenic induction ability of a PAMPS/PDMAAm double-network (DN) gel and found it to induce chondrogenesis in animal osteochondral defect models. The purpose of this study was to investigate whether the healing p...

AIMS/INTRODUCTION Patients with diabetic nephropathy (DN) typically show varying degrees of proteinuria and renal impairment. Because these clinical signs are frequently observed in other glomerulopathies, renal biopsy is required to make a definitive diagnosis of DN. We carried out the present study to evaluate the significance of renal biopsy for patients who have been presumptively diagnosed...

The ANS- (1-anilino-8-naphthalene sulfonate) anion is strongly, dominantly bound to cationic groups of water-soluble proteins and polyamino acids through ion pair formation. This mode of ANS- binding, broad and pH dependent, is expressed by the quite rigorous stoichiometry of ANS- bound with respect to the available summed number of H+ titrated lysine, histidine, and arginine groups. By titrati...

Progression of diabetic nephropathy (DN) is commonly defined by an increase in albuminuria from normoalbuminuria to microalbuminuria and from microalbuminuria to macroalbuminuria. Although many therapeutic interventions, including reducing hyperglycemia and intraglomerular pressure, have been shown to slow down the progression of DN, many patients still develop end-stage renal disease. A major ...
