Cell Sizes Matter for Industrial Bioproduction, a Case of Polyhydroxybutyrate.

Most bacterial cells are 1-2 microns in size, limiting intracellular products like polyhydroxyalkanoates (PHA) accumulation. Cell size is regulated by key genes such as mreB and minCD, which encode cellular skeleton protein and control cell fission ring location, respectively. Their expression changes significantly affect microbial growth.

[Single-incision versus conventional laparoscopic cholecystectomy: a meta-analysis].

Objective: To study feasibility and security of single-incision laparoscopic cholecystectomy (SILC).

Methods: Clinical trials comparing SILC with conventional laparoscopic cholecystectomy (LC) for benign gallbladder disease published from 2010 to 2012 were retrieved. A meta-analysis was conducted to evaluate operative time, blood loss, conversion rate, post-operative pain, wound satisfaction score, post-operative hospital stay and post-operative complications between SILC group and LC group.
