Numerous insertions of mitochondrial DNA in the genome of the northern mole vole, Ellobius talpinus.

Background: Ellobius talpinus is a subterranean rodent representing an attractive model in population ecology studies due to its highly special lifestyle and sociality. In such studies, mitochondrial DNA (mtDNA) is widely used. However, if nuclear copies of mtDNA, aka NUMTs, are present, they may co-amplify with the target mtDNA fragment, generating misleading results.

Strapdown Inertial Navigation Systems for Positioning Mobile Robots-MEMS Gyroscopes Random Errors Analysis Using Allan Variance Method.

A problem of estimating the movement and orientation of a mobile robot is examined in this paper. The strapdown inertial navigation systems are often engaged to solve this common obstacle. The most important and critically sensitive component of such positioning approximation system is a gyroscope.

[Central lymphodissection in carcinoma of the thyroid gland].

Experience with central lymphodissection (CLD) was analyzed in 93 patients with primary thyroid cancer (pT1-4aN0-1a). Prophylactic central lymphodissection was fulfilled in 48 patients, therapeutic CLD in 45 patients. The size and spread of the primary thyroid tumor had no difference in both groups of patients.

[Simultaneous operations during laparoscopic cholecystectomy].

Simultant laparoscopic operations were performed in 1993-2003 yrs period in 321 patients, including 287--using laparoscopic and 34--the combined (laparoscopic and open) access. Concurrent diseases were diagnosed preoperatively in 219 (68.2%) of patients and were disclosed while doing intraoperative revision--in 102 (31.
