Evolution and neutralization escape of the SARS-CoV-2 BA.2.86 subvariant
No full textOmicron BA.2.86 subvariant differs from Omicron BA.2 as well as recently circulating variants by over 30 mutations in the spike protein alone. Here we report on the isolation of the live BA.2.86 subvariant from a diagnostic swab collected in South Africa which we tested for escape from neutralizing antibodies and viral replication properties in cell culture. We found that BA.2.86 does not have significantly more escape relative to Omicron XBB.1.5 from neutralizing immunity elicited by either Omicron XBB-family subvariant infection or from residual neutralizing immunity of recently collected sera from the South African population. BA.2.86 does have extensive escape relative to ancestral virus with the D614G substitution (B.1 lineage) when neutralized by sera from pre-Omicron vaccinated individuals and relative to Omicron BA.1 when neutralized by sera from Omicron BA.1 infected individuals. BA.2.86 and XBB.1.5 show similar viral infection dynamics in the VeroE6-TMPRSS2 and H1299-ACE2 cell lines. We also investigate the relationship of BA.2.86 to BA.2 sequences. The closest BA.2 sequences are BA.2 samples from Southern Africa circulating in early 2022. Similarly, many basal BA.2.86 sequences were sampled in Southern Africa. This suggests that BA.2.86 potentially evolved in this region, and that unobserved evolution led to escape from neutralizing antibodies similar in scale to recently circulating strains of SARS-CoV-2.Full Tex
Magnetocrystalline anisotropy measurements on some polycrystalline rare-earth cobolt alloys
No full textThe singular point detection (SPD) technique recently developed by Asti and Rinaldi was used for anisotropy field (BA) measurements on a range of polycrystalline rare-earth cobalt alloys. The anisotropy constant, K, , was estimated from magnetization measurements on field-aligned samples and the anisotropy constant, K,, was calculated from the relation:2K, + 4K,BA = - M where Ms is the saturation magnetization. Temperatures from 4.2K sto 300 K were used with pulsed magnetic fields up to 20T.The temperature dependence of B A in YCos was observed to be linear while that in ThCos showed a broad peak around 190K. In NdCo, , BA and K, showed a decrease while K2 showed an increase with decreasing temperature. BA in (Y 1 _x2Cox)Cos for x = 0 to 0.129 showed an increase with x for annealed samples while that for x = 0.05 to 0.129,showed a decrease in the as-east state.The temperature dependence of anisotropy in Ere Co„ and Tm, Co, indicated the dominance of the rare-earth sub-lattices in these alloys. Attempts to fit K, (T) with a power law gave powers of 2.2 - 2.5 for these compounds while those for Sm, C gave a power of about 27. The latter however showed an excellent agreement with the model of Carr.Measurements on the Y2 (CoxFel _x) series indicated strong temperature and composition (x) dependences in BA, K, and K2 _ These results can be interpreted in terms of preferential substitution of Fe on different ~o lattice sites. Results on Pr, (Cons FeOA )revealed evidence of a magnetization process of first order and were found to be in good agreement with the theory of first order magnetization rotations.Attempts to prepare 5 : 19 phases (for R = Cc, Pr, Nd, La), were successful only in the case of Ces Co. Even in this alloy, I : 5 and 2 : 7 phases were found to be present. BA vah,es of this alloy as a function of temperature were measured.</p
Longitudinal analysis of serum neutralization of SARS-CoV-2 Omicron BA.2, BA.4, and BA.5 in patients receiving monoclonal antibodies
No full textThe emergence of Omicron sublineages impacts the therapeutic efficacy of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) monoclonal antibodies (mAbs). Here, we evaluate neutralization and antibody-dependent cellular cytotoxicity (ADCC) activities of 6 therapeutic mAbs against Delta, BA.2, BA.4, and BA.5. The Omicron subvariants escape most antibodies but remain sensitive to bebtelovimab and cilgavimab. Consistent with their shared spike sequence, BA.4 and BA.5 display identical neutralization profiles. Sotrovimab is the most efficient at eliciting ADCC. We also analyze 121 sera from 40 immunocompromised individuals up to 6 months after infusion of Ronapreve (imdevimab + casirivimab) or Evusheld (cilgavimab + tixagevimab). Sera from Ronapreve-treated individuals do not neutralize Omicron subvariants. Evusheld-treated individuals neutralize BA.2 and BA.5, but titers are reduced. A longitudinal evaluation of sera from Evusheld-treated patients reveals a slow decay of mAb levels and neutralization, which is faster against BA.5. Our data shed light on antiviral activities of therapeutic mAbs and the duration of effectiveness of Evusheld pre-exposure prophylaxis
Quercetin Phytosome® as a potential candidate for managing COVID-19
No full textWhen looking for new antiviral compounds aimed to counteract the COVID-19, a disease caused by the recently identified novel Coronavirus (SARS-CoV-2), the knowledge of the main viral proteins is fundamental. The major druggable targets of SARS-CoV-2 include 3-chymotrypsin-like protease (3CLpro), papain-like protease (PLpro), RNA-dependent RNA polymerase, and spike (S) protein. Molecular docking studies have highlighted that quercetin, a natural polyphenol belonging to the flavonol class, inhibits 3CLpro, PLpro and S proteins. Biophysical technics have then very recently confirmed that quercetin is reasonably a potent inhibitor of 3CLpro. The likely antiviral properties of quercetin are anyway challenged by its very poor oral bioavailability profile and any attempt to overcome this limit should be welcome. A phospholipid delivery form of quercetin (Quercetin Phytosome (R)) has been recently tested in humans to evaluate a possible improvement in oral bioavailability. After hydrolysis of the conjugated form (mainly glucuronide) of quercetin found in human plasma, the pharmacokinetics results have demonstrated an increased bioavailability rate by about 20-fold for total quercetin. It has been also observed that the presence of specific glucuronidase could yield free systemic quercetin in human body. Taking also into considerations its anti-inflammatory and thrombin-inhibitory actions, a bioavailable form of quercetin, like Quercetin Phytosome (R), should be considered a possible candidate to clinically face COVID-19
Boundary Algebra: A Simpler Approach to Boolean Algebra and the Sentential Connectives
No full textBoundary algebra [BA] is a algebra of type , and a simplified notation for Spencer-Brown’s (1969) primary algebra. The syntax of the primary arithmetic [PA] consists of two atoms, () and the blank page, concatenation, and enclosure between ‘(‘ and ‘)’, denoting the primitive notion of distinction. Inserting letters denoting, indifferently, the presence or absence of () into a PA formula yields a BA formula. The BA axioms are A1: ()()= (), and A2: “(()) [abbreviated ‘⊥’] may be written or erased at will,” implying (⊥)=(). The repeated application of A1 and A2 simplifies any PA formula to either () or ⊥. The basis for BA is B1: abc=bca (concatenation commutes & associates); B2, ⊥a=a (BA has a lower bound, ⊥); B3, (a)a=() (BA is a complemented lattice); and B4, (ba)a=(b)a (implies that BA is a distributive lattice). BA has two intended models: (1) the Boolean algebra 2 with base set B={(),⊥}, such that () ⇔ 1 [dually 0], (a) ⇔ a′, and ab ⇔ a∪b [a∩b]; and (2) sentential logic, such that () ⇔ true [false], (a) ⇔ ~a, and ab ⇔ a∨b [a∧b]. BA is a self-dual notation, facilitates a calculational style of proof, and simplifies clausal reasoning and Quine’s truth value analysis. BA resembles C.S. Peirce’s graphical logic, the symbolic logics of Leibniz and W.E. Johnson, the 2 notation of Byrne (1946), and the Boolean term schemata of Quine (1982).Boundary algebra; boundary logic; primary algebra; primary arithmetic; Boolean algebra; calculation proof; G.
