Measurement of Λ_{b}^{0}, Λ_{c}^{+}, and Λ Decay Parameters Using Λ_{b}^{0}→Λ_{c}^{+}h^{-} Decays.

A comprehensive study of the angular distributions in the bottom-baryon decays Λ_{b}^{0}→Λ_{c}^{+}h^{-}(h=π,K), followed by Λ_{c}^{+}→Λh^{+} with Λ→pπ^{-} or Λ_{c}^{+}→pK_{S}^{0} decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 9  fb^{-1} collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity (CP) asymmetries are measured, with no significant CP violation observed. For the first time, the Λ_{b}^{0}→Λ_{c}^{+}h^{-} decay parameters are measured.

A New Antibody-Cytokine Construct Targeting Natural Killer Cells: An Immunotherapeutic Approach to Chronic Lymphocytic Leukemia.

In chronic lymphocytic leukemia (CLL), natural killer (NK) cells show a dysfunctional phenotype that correlates with disease progression. Our aim was to restore NK cell functionality in CLL through a specifically targeted IL15-stimulating activity; IL15 targeting could, in fact, potentiate the activity of NK cells and reduce off-target effects. We designed and developed a cis-acting immunocytokine composed of an anti-CD56 single-chain Fragment variable (scFv) and IL15, labeled scFvB1IL15.

Modulation of CCR5 expression and R5 HIV-1 infection in primary macrophages exposed to sera from HESN, LTNP, and chronically HIV-1 infected people with or without natural antibodies to CCR5.

CCR5 is the main co-receptor for HIV-1 cell entry and it plays key roles in HIV-1 mucosal transmission. Natural anti-CCR5 antibodies were found in HIV-1-exposed seronegative and long-term non-progressor subjects, suggesting a role in controlling viral replication in vivo. We assessed the effect of sera containing or not natural anti-CCR5 antibodies, on membrane CCR5 level and HIV-1 infection in primary macrophages.

Changes in Soil Chemical Attributes in an Agrosilvopastoral System Six Years After Thinning of Eucalyptus.

The changes in soil chemical attributes in agrosilvopastoral systems after the thinning of trees are unclear. To address this gap, this study evaluated the effects of the thinning of eucalyptus hybrid Urograndis H-13 ( S. T.
