Transcriptional coordination of physiological responses in Nannochloropsis oceanica CCMP1779 under light/dark cycles.

Nannochloropsis oceanica CCMP1779 is a marine unicellular stramenopile and an emerging reference species for basic research on oleogenic microalgae with biotechnological relevance. We investigated its physiology and transcriptome under light/dark cycles. We observed oscillations in lipid content and a predominance of cell division in the first half of the dark phase.

[Modeling the dynamics of the effective population size of the Okhotsk Sea pollock in the Holocene era on the basis of genetic variability in the Nd2 and Cytb mtDNA loci].

We used Bayesian statistics to investigate the demographic history of the walleye pollock in the sea of Okhotks based on polymorphisms of sequences of the Nd2 and Cytb mitochondrial genes. We determined the average age for the Most Recent Common Ancestor (MRCA) as 44.1 ± 2 and 52.

Accuracy of intraoperative computed tomography-based navigation for placement of percutaneous pedicle screws.

MISS techniques have gained recent popularity. The proposed benefits of these techniques include reduced tissue trauma, reduced blood loss, less perioperative pain, and a quicker recovery and return to normal activities. The purpose of this study was to evaluate the accuracy of intraoperative computed tomography (CT)-based navigation for placement of percutaneous pedicle screws in a cadaveric model.

Estimating the effective radiation dose imparted to patients by intraoperative cone-beam computed tomography in thoracolumbar spinal surgery.

Study Design: Observational.

Objective: To estimate the radiation dose imparted to patients during typical thoracolumbar spinal surgical scenarios.

Summary Of Background Data: Minimally invasive techniques continue to become more common in spine surgery.
