Interactive three-dimensional atlas of the mineralized skeleton of the sand tiger shark .

Non-invasive computed tomography (CT) of an adult sand tiger shark Rafinesque, 1810 is used to provide an interactive three-dimensional 'general' shark (Selachimorpha) anatomy atlas. Given its post-cranial body morphology, the sand tiger shark appeared to be a well-chosen candidate and through comparison of the sand tiger shark with several other representatives of all eight established orders of sharks, we confirm that the relatively large degree of mineralization of the endoskeleton, along with the overall size, makes the sand tiger shark an ideal candidate for skeletal segmentation and construction of a skeletal atlas using conventional CT. This atlas both increases accessibility to the internal morphological features of the sand tiger shark and provides a more generalized overview of the skeletal anatomy of sharks and can aid as a supplement to destructive fresh dissection of specimens in the future and the construction of future skeletal atlases of other less mineralized sharks.

The association of religious factors with mental health-service utilisation and satisfaction in a mixed Sámi and Norwegian adult population: Adopting the SAMINOR 2 Questionnaire Survey.

The Indigenous Sámi have poorer mental health than the majority population and fairly equal access to professional mental healthcare. Despite this condition, certain studies indicate that this group is underrepresented among the users of such services. Religion or spirituality (R/S) often influences mental health-service utilisation and satisfaction among other Indigenous peoples and ethnic minorities.

Long-Term Oncologic Outcomes After Laparoscopic Versus Open Resection for Colorectal Liver Metastases : A Randomized Trial.

Background: Despite the recent worldwide dissemination of laparoscopic liver surgery, no high-level evidence supports the oncologic safety of this approach.

Objective: To evaluate long-term oncologic outcomes after laparoscopic versus open liver resection in patients with colorectal metastases.

Design: A single-center, assessor-blinded, randomized controlled trial (OSLO-COMET [Oslo Randomized Laparoscopic Versus Open Liver Resection for Colorectal Metastases Trial]).

Environmental DNA concentrations are correlated with regional biomass of Atlantic cod in oceanic waters.

Environmental DNA (eDNA) has emerged as a powerful approach for studying marine fisheries and has the potential to negate some of the drawbacks of trawl surveys. However, successful applications in oceanic waters have to date been largely focused on qualitative descriptions of species inventories. Here we conducted a quantitative eDNA survey of Atlantic cod () in oceanic waters and compared it with results obtained from a standardized demersal trawl survey.
