Spatiotemporal trends of aerosol provenance and trace metal concentrations in the northeast subarctic Pacific Ocean.

The long-range transport of naturally occurring and anthropogenic aerosols originating from Asian deserts and megacities, respectively, can have a significant impact on the biogeochemical cycling of metals in the Fe-limited, high nutrient-low chlorophyll (HNLC) region of the northeast (NE) subarctic Pacific Ocean. These aerosols can deposit essential (e.g.

Dog agility tunnel risks for incidents.

Background: Flexible tunnels are the second most common obstacle on all dog agility courses, surpassed only by jumps. There has been a lot of debate and concern regarding risk factors associated with slips, falls and delayed exits (unseen slips, missteps, trips, falls). However, only one study was found which focused on the tunnel-related injuries, and it relied on handler reporting and did not consider base rates of the risk factors.

Quantum Correction to the Orbital Hall Effect.

Evaluations of the orbital Hall effect (OHE) have retained only interband matrix elements of the position operator. Here, we evaluate the OHE including all matrix elements of the position operator, including the technically challenging intraband elements. We recover previous results and find quantum corrections due to the noncommutativity of the position and velocity operators and interband matrix elements of the orbital angular momentum.

Vitamin B, B, and B Intakes and Risk of Gastric Cancer: Findings from a Case-Control Study.

Background/objectives: Gastric cancer is one of the leading malignancies worldwide. B vitamins play important roles in DNA synthesis and methylation because they are considered co-enzymes in one-carbon metabolism. There is inconclusive evidence regarding the associations between dietary vitamins B, B, and B with the risk of gastric cancer in different epidemiologic studies.

Biliverdinuria Caused by Exonic Deletions in Two Dogs with Green Urine.

In heme degradation, biliverdin reductase catalyzes the conversion of biliverdin to bilirubin. Defects in the biliverdin reductase A gene () causing biliverdinuria are extraordinarily rare in humans, and this inborn error of metabolism has not been reported in other mammals. The objective of this study was to diagnose biliverdinuria and identify the causal variants in two adult mixed-breed dogs with life-long green urine.
