TBE best results of cataract surgery are achieved by the intracapsular technique. McNamara (1868) practised this procedure; he would make the incision in the lower half of the cornea and apply pressure with the finger from above. Molroney, working at Amritsar and Jullundur, extended this procedure to all types of senile cataract. His successor Smith (1928) noticed that the rate of vitreous prol...

PURPOSE to verify the accuracy of uterine cervix cytology for HPV diagnosis, as compared to polymerase chain reaction (PCR) in samples of women with HIV. METHODS 158 patients who had undergone a first collection of material from the uterine cervix with Ayre's spatula for PCR were included in the study. Then, another collection with Ayre's spatula and brush for oncotic cytology was performed. ...

BACKGROUND Plants integrate signals from the environment and use these to modify the timing of development according to seasonal cues. Seed germination is a key example of this phenomenon and in Arabidopsis is promoted by the synergistic interaction of light and low temperatures in dormant seeds. This signaling pathway is known to converge on the regulation of the gibberellin (GA) biosynthetic ...

Introduction: Exfoliative cytology in age estimation is a simple, painless, less invasive collection of exfoliative cells from epithelial layers, used as diagnostic aid for estimation. The oral cavity an ideal site with physiological turnover cells, decreases the increases show variation cellular morphological changes. Age one important factors to identify individual and also helps know chronol...

Background and Objective: Cervical cancer involves many women annually and Pop smear test has played a significant role in reducing its mortality and for this reason, its improvement is very essential. In this respect, cervex brush is a new tool that has been introduced in many countries. Therefore, this...

Dynamic adhesion is a key ability for animals to climb smooth surfaces. Spiders evolved, convergent geckos, dry adhesive system made of setae branching into smaller microtrichia ending as spatulae. Several previous studies concentrated either on the whole claw tuft spider´s foot that consists attachment or single contact elements, with spatula-shaped tips. Here, spider Cupiennius salei was exam...

Freshly matured seeds exhibit primary dormancy, which prevents germination until environmental conditions are favorable. The establishment of dormancy occurs during seed development and involves both genetic and environmental factors that impact on the ratio of two antagonistic phytohormones: abscisic acid (ABA), which promotes dormancy, and gibberellic acid, which promotes germination. Althoug...
