SARS-CoV-2 is the causative agent for the ongoing COVID19 pandemic, and this virus belongs to the Coronaviridae family. Like other members of this family, the virus possesses a positive-sense single-stranded RNA genome. The genome encodes for the nsp12 protein, which houses the RNA-dependent-RNA polymerase (RdRP) activity responsible for the replication of the viral genome. A homology model of nsp12 was prepared using the structure of the SARS nsp12 (6NUR) as a model. The model was used to carry out in silico screening to identify molecules among natural products, or Food and Drug Administration-approved drugs that can potentially inhibit the activity of nsp12. This exercise showed that vitamin B12 (methylcobalamin) may bind to the active site of the nsp12 protein. A model of the nsp12 in complex with substrate RNA and incoming NTP showed that vitamin B12 binding site overlaps with that of the incoming nucleotide. A comparison of the calculated energies of binding for RNA plus NTP and methylcobalamin suggested that the vitamin may bind to the active site of nsp12 with significant affinity. It is, therefore, possible that methylcobalamin binding may prevent association with RNA and NTP and thus inhibit the RdRP activity of nsp12. Overall, our computational studies suggest that methylcobalamin form of vitamin B12 may serve as an effective inhibitor of the nsp12 protein.Combination therapies that target multiple pathways involved in immune rejection of transplants hold promise for patients in need of restorative surgery. Herein, a noninteracting multiphase molecular assembly approach is developed to crystallize tofacitinib, a potent JAK1/3 inhibitor, within a shear-thinning self-assembled fibrillar peptide hydrogel network. The resulting microcrystalline tofacitinib hydrogel (MTH) can be syringe-injected directly to the grafting site during surgery to locally deliver the small molecule. The rate of drug delivered from MTH is largely controlled by the dissolution of the encapsulated microcrystals. A single application of MTH, in combination with systemically delivered CTLA4-Ig, a co-stimulation inhibitor, affords significant graft survival in mice receiving heterotopic heart transplants. Locoregional studies indicate that the local delivery of tofacitinib at the graft site enabled by MTH is required for the observed enhanced graft survival.
International guidelines recommend hereditary thoracic aortic diseases (HTADs) to be managed in multidisciplinary aorta clinics.

To study HTAD patient's experiences with a aortopathy clinic in Norway and to review the literature on aortopathy clinics.

(a) A systematic scoping review of research on multidisciplinary clinics for HTADs. (b) A cross-sectional postal questionnaire study to investigate patient experiences with the health-services. Fifty consecutive patients from the aortopathy clinic and 50 controls in usual care were invited to participate.

The review identified eight publications on aortopathy clinics. Although the papers were not judged for quality, these showed promising results from such clinics in terms of diagnostics and increased adherence to guideline-directed therapy. The survey constituted thirty-seven (74%) patients and 22 (44%) controls who responded to postal questionnaires. Both groups reported delays in diagnostics and follow-up appointments prior to the start of the clinic. Patients indicated high satisfaction with the aortopathy clinic, whereas controls reported poor coordination of medical follow-up. Individuals in both groups struggled with disease self-management.

Norwegian patient experiences found the aortopathy clinic beneficial. According to studies included in the review, disease management in aortopathy clinics may improve patient satisfaction, diagnostics and follow-up. Effect studies may further document the benefits of clinic organization, treatment, cost-efficiency and patient experiences.

Recently, we demonstrated that the chemokine-receptor CXCR2 plays a critical role in the recruitment of monocytes/macrophages and the development of hypertension and cardiac remodelling. However, the role of CXCR2 in the pathogenesis of hypertensive AF remains unclear. AF was induced in Wistar-Kyoto rats (WKYs) and spontaneously hypertensive rats (SHRs) administered with the CXCR2 inhibitor SB225002. Atrial remodelling, pathological changes and electrophysiology were examined. Our results showed that the chemokine CXCL1 and its receptor CXCR2 were markedly increased in atrial tissue of SHRs compared with WKYs. The administration of SB225002 to SHRs significantly reduced the elevation of blood pressure, AF inducibility and duration, atrial remodelling, recruitment of macrophages, superoxide production and conduction abnormalities compared with vehicle treatment. The administration of SB225002 to SHRs also reversed pre-existing AF development, atrial remodelling, inflammation and oxidative stress. These effects were associated with the inhibition of multiple signalling pathways, including TGF-β1/Smad2/3, NF-κB-P65, NOX1, NOX2, Kir2.1, Kv1.5 and Cx43. In conclusion, this study provides new evidence that blocking CXCR2 prevents and reverses the development of AF in SHRs, and suggests that CXCR2 may be a potential therapeutic target for hypertensive AF.
Neuroblastoma amplified sequence (NBAS)-associated disease has a wide phenotypic spectrum, including infantile liver failure syndrome type 2 (ILFS2, OMIM #616483), short stature with optic nerve atrophy and Pelger-Huët anomaly (SOPH) syndrome (OMIM #614800), and a combined phenotype overlapping ILFS2 and SOPH syndrome. The mutation spectra of NBAS and its genotype-phenotype correlation among Chinese were not clear.

Clinical and genetic data were retrospectively collected from the medical charts of patients with biallelic NBAS mutations, as well as from Chinese patients in previously published reports.

Fourteen new patients were identified, including 10 novel mutations c.648-1G>A, c.2563_c.2577+5del/p.His855_Gln859del, c.3115C>T/p.Gln1039Ter, c.3284G>A/p.Trp1095Ter, c.2570C>T/p.Ala857Val, c.6859G>T/p.Asp2287Tyr, c.1028G>A/p.Ser343Asn, c.1177_1182delinsAGATAGA/p.Val393ArgfsTer2, c.3432_3435dupCAGT/p.Ala1146GlnfsTer14, and c.680_690dupACTGTTTCAGC/p.Phe231ThrfsTer35. All 14 patients presented as fever-triggered liver injury, including nine patients that satisfied the criteria of acute liver failure (ALF) in whom c.
