'Cold SSCP': a simple, rapid and non-radioactive method for optimized single-strand conformation polymorphism analyses.

Tadashi Hongyo, +3 more
- 11 Aug 1993 - 
TL;DR: A rapid (< 2.5 hrs) method for single-strand conformation polymorphism (SSCP) analysis of PCR products that allows the use of ethidium bromide staining is described and has additional advantages of dramatically increased speed, precise temperature control, reproducibility, and easily and inexpensively obtainable reagents and equipment.
Journal ArticleDOI

Alteration of gastrointestinal mucin by fiber feeding in rats

Subramaniam Satchithanandam, +4 more
- 01 Oct 1990 - 
TL;DR: Fiber-induced increments in gastrointestinal mucin production or availability may be responsible for several reported consequences of fiber feeding, such as more rapid transit times and delayed or impaired nutrient absorption.
Journal ArticleDOI

Hepatic toxicity of unmodified and time-release preparations of niacin

Jeanne I. Rader, +2 more
- 01 Jan 1992 - 
TL;DR: In doses that achieve equivalent reductions in serum lipids, hepatic toxicity occurred more frequently with time-release preparations than with unmodified preparations.
Journal ArticleDOI

Effects of dietary fibers on gastrointestinal mucin in rats

Subramaniam Satchithanandam, +3 more
- 01 Jul 1996 - 
TL;DR: Increases in gastric and colonic mucin levels caused by psyllium treatment may protect these organs as well as alter nutrient absorption.
Journal ArticleDOI

Mutated and wild-type p53 expression and HPV integration in proliferative verrucous leukoplakia and oral squamous cell carcinoma.

Rajaram Gopalakrishnan, +8 more
- 01 Apr 1997 - 
TL;DR: In this paper, the frequencies of overexpression and mutation in the p53 tumor suppressor gene were examined in proliferative verrucous leukoplakia and oral squamous cell carcinoma with immunohistochemistry and single-strand conformation polymorphism analysis of DNA fragments amplified by polymerase chain reaction.
