- New variants in the SARS-CoV-2 pandemic are more contagious (Alpha/Delta), evade neutralizing antibodies (Beta), or both (Omicron). This poses a challenge in vaccine development according to WHO. We designed a more universal SARS-CoV-2 DNA vaccine containing receptor-binding domain loops from the huCoV-19/WH01, the Alpha, and the Beta variants, combined with the membrane and nucleoproteins. The vaccine induced spike antibodies crossreactive between huCoV-19/WH01, Beta, and Delta spike proteins that neutralized huCoV-19/WH01, Beta, Delta, and Omicron virus in vitro. The vaccine primed nucleoprotein-specific T cells, unlike spike-specific T cells, recognized Bat-CoV sequences. The vaccine protected mice carrying the human ACE2 receptor against lethal infection with the SARS-CoV-2 Beta variant. Interestingly, priming of cross-reactive nucleoprotein-specific T cells alone was 60% protective, verifying observations from humans that T cells protect against lethal disease. This SARS-CoV vaccine induces a uniquely broad and functional immunity that adds to currently used vaccines.

- Vertebral compression fractures were simulated by making a hole into sheep vertebrae and by injecting a stabilizing material. The injectable bio-ceramic Xeraspine™ was evaluated together with a commercially available PMMA (Vertebroplastic™) as the reference material. The Vertebrae were harvested after 7 days and prepared for microscopy. The samples were deposited with gold on the surface and thereafter subjected to SEM and EDX analysis. It was found that the Xeraspine-bone interface was composed of a mixture of elements. The Vertebroplastic implant was embedded in a carbon containing tissue, likely a soft tissue capsule. The Xeraspine sample was subjected to high resolution analysis in the TEM combined with EDX measurements. The TEM sample was prepared with a novel technique for preparation of the tissue-material interface (FIB). In the TEM analysis it was found that the interface region consists of ZrO2 together with a mixture possibly consisting of katoite and apatite formed during setting and/or originating from the boneapatite.

- The effect of cerebral ischemia on the vasopressin response to hemorrhagic hypotension and on the hepatic and muscular glycogen mobilization was studied in rats. The addition of cerebral ischemia to the hemorrhage required withdrawal of significantly more blood to lower mean arterial pressure (MAP) to 50 mmHg but not if combined with ganglionic blockade. The increase in plasma vasopressin concentration during hypotension was not significantly different in rats with and without concurrent cerebral ischemia. Ganglionic blockade blunted the vasopressin response. Thus cerebral ischemia in fact attenuated the vasopressin response to hemorrhage. One hour after the insult, the hormone concentration in rats exposed to combined cerebral ischemia and hemorrhagic hypotension without ganglionic blockade was still above control levels and higher than in all other groups. Concomitantly the hepatic but not the muscular glycogen concentration in these rats was significantly lower than in the other groups.
