A systematic review and meta-analysis of efficacy of vasopressin as a vasoconstrictive and uterotonic drug in laparoscopic myomectomy.

Introduction: Laparoscopic myomectomy is a commonly performed operation with fast recovery and excellent results. However, haemorrhagic nature of the operation mandates us to use variety of vasoconstrictive and uterotonic agents. Amongst which, one of them is vasopressin.

An Observational Study of Factors affecting CA125 Levels in Premenopausal Women.

Background: CA125 levels show a variation in premenopausal women during the menstrual cycle. Moreover, various modifiable and non-modifiable factors affect its value which needs to be taken into account while interpreting the results. The study was done with an objective (1) to determine differences in CA125 levels during the mid-cycle and menstrual phase of menstruation and (2) to determine the factors (demographic and clinical) that may affect CA125 values.

BRED: a simple and powerful tool for constructing mutant and recombinant bacteriophage genomes.

Advances in DNA sequencing technology have facilitated the determination of hundreds of complete genome sequences both for bacteria and their bacteriophages. Some of these bacteria have well-developed and facile genetic systems for constructing mutants to determine gene function, and recombineering is a particularly effective tool. However, generally applicable methods for constructing defined mutants of bacteriophages are poorly developed, in part because of the inability to use selectable markers such as drug resistance genes during viral lytic growth.
