The present inventors identified for the first time a germline genomic alteration that accounts for familial myeloproliferative neoplasms (MPN) and myeloid malignancies. More precisely, they identified a 700 kb germline duplication that proposes patients to essential thrombocythemia (ET) with a high frequency of evolution to myelofibrosis (MF), secondary myelodysplastic syndromes (MDS) or acute myeloid leukemia (AML). Two out of the 6 duplicated genes (namely ATG2B and GSKIP) have been shown to be overexpressed in hematopoietic progenitors, and this overexpression cooperates with classical mutations in JAK2, MPL, and CALR to generate the MPN phenotype. The presence of the 700 kb germline duplication is thus of poor prognosis for a MPN patient. The present invention discloses a method for detecting a predisposition of developing a MPN, as well as a prognostic method for assessing the probability that an ET-suffering patient will develop a myelofibrosis, a secondary MDS or an AML. It also discloses a treating method for delaying MPN worsening, said treating method involving the inhibition of the ATG2B and GSKIP duplicated genes. |

Deuterated antimicrobial compounds
Substituted nitrobenzothiazinones (BTZs) are potent antituberculosis prodrugs that are reductively activated to produce nitroso moieties that form covalent adducts with a cysteine residue of decaprenylphosphoryl-β-D-ribose-2′-oxi-dase (DprE1) of Mycobacterium tuberculosis (Mtb). The resulting cell wall synthesis inhibition is lethal to Mtb, leading to consideration of development of BTZs for clinical use. The hydride-induced reduction of the nitroaromatic proceeds by reversible formation of the corresponding Meisenheimer complex. Herein we demonstrate that chemical reduction of BTZ043 with NaBD4 followed by reoxidation incorporates deuterium into the core nitro aromatic warhead. Subsequent reduction of the deuterated species is not affected, but, as expected, reoxidation is slowed by the deuterium isotope effect, thus prolonging the lifetime of the active nitroso oxidation state. |

Determination of vehicle pullover location considering ambient conditions
This document describes methods and systems for enabling an autonomous vehicle (AV) to determine a path to a stopping location. The AV will determine a desired stop location (DSL) that is associated with a service request. The AV's motion control system will move the AV along a path to the DSL. While moving along the path, the AV's perception system will detect ambient conditions near the DSL. The ambient conditions will be parameters associated with a stopping rule. The AV will apply the stopping rule to the ambient conditions to determine whether the stopping rule permits the AV to stop at the DSL. If the stopping rule permits the AV to stop at the DSL, the motion control system will move the AV to, and stop at, the DSL. Otherwise, the motion control system will not stop the AV at the DSL. |

The sliding member is slidably received in the receiving room, and two ends thereof are a piston and a driving portion respectively. A gas cavity is defined between the piston and the blind end. The sliding member tends to move toward the blind end due to the restoring mechanism. The restriction member is connected to the driving portion and radially deforms when the sliding member slides so as to fix or to release the tool-holder. The sliding member slides outward when the gas cavity is injected with gas via the gas channel. |
