摘要:
A rotary electric machine includes a stator and a rotor. The rotor has at least one permanent magnet arranged in a d-axis magnetic path. The rotor includes a magnetic gap part located between the permanent magnet arranged in the d-axis magnetic path of one pole and an adjacent magnet with a different polarity, such that a d-axis magnetic flux forms a d-axis bypass passing through an area other than the permanent magnet. The d-axis bypass provides a magnetic resistance in a d-axis direction that is set below a magnetic resistance in a q-axis direction that is orthogonal to the d-axis resistance.
摘要:
The methods described herein are based on the observation that oscillations in breath isotope ratio data can be used for the purpose of identifying an "unhealthy" state in an organism such as a human. Described herein are methods of determining the state of health of an individual, such as the transition from healthy to infected, by identifying changes in oscillation modes in breath isotope ratio data. Changes in the frequency and/or amplitude of the oscillation modes are correlated with the heath of the individual. The methods can advantageously be used to provide information about the health of an individual in shorter periods of time than previous methods.
摘要:
Dithioamine reducing agents useful for the reduction of disulfide bonds. The reducing agents of this invention are useful, for example, to reduce disulfide bonds, particularly in proteins, or to prevent the formation of disulfide bonds, particularly in proteins and other biological molecules. Reducing agents of this invention can be employed to regulate protein function in proteins in which a sulfhydryl group is associated with biological activity. Reducing agents of this invention can prevent inactivation of a given protein or enhance activation of a given protein or other biological molecule in vitro and/or in vivo. Reducing agents of this invention can prevent or reduce oxidation of cysteine residues in proteins and prevent the formation of reduced activity protein dimers (or other oligomers). Reducing agents of this invention are useful and suitable for application in a variety of biological applications, particularly as research and synthetic reagents.
摘要:
This invention discloses 2-methylene-vitamin D analogs, and specifically (20S)-1α,25 -dihydroxy-2-methylene-vitamin D3 as well as (5E)-(20S)-1α,25-dihydroxy-2 -methylene-vitamin D3 and (20R)-1α,25-dihydroxy-2-methylene-vitamin D3, as well as pharmaceutical uses therefor. These compounds exhibit relatively high binding activity and pronounced activity in arresting the proliferation of undifferentiated cells and inducing their differentiation to the monocyte thus evidencing use as an anti-cancer agent especially for the treatment or prevention of osteosarcoma, leukemia, colon cancer, breast cancer, skin cancer or prostate cancer. These compounds also have relatively high calcemic activities evidencing use in the treatment of bone diseases.

These compounds also have relatively high calcemic activities evidencing USC in the treatment of bone diseases. Formula (I).
摘要:
A method of purifying 1α-hydroxy-2-methylene-18,19-dinor-homopregnacalciferol to obtain 1α-hydroxy-2-methylene-18,19-dinor-homopregnacalciferol in crystalline form using precipitation with hexane from ethyl acetate. A method of preparing 1α-hydroxy-2-methylene-18,19-dinor-homopregnacalciferol crystals acceptable for X-ray experiment using precipitation with hexane from benzene by diffusive exchange of the solvents is also described.
