Weight-loss interventions generally improve lipid profiles and reduce cardiovascular disease risk, but effects are variable and may depend on genetic factors. We performed a genetic association analysis of data from 2,993 participants in the Diabetes Prevention Program to test the hypotheses that a genetic risk score (GRS) based on deleterious alleles at 32(More)
A relativistic model for the quasifree photoproduction of η meson from complex nuclei is developed. The interactions between fields are introduced through effective Lagrangians. Contributions from several nucleon resonances as well as nucleon Born terms and vector meson exchange diagrams are included. Nucleon and η wave functions are solutions of Dirac and(More)
We study the effect of wave function orthogonality in the rela-tivistic treatment of the nucleon removal reactions (γ, p) and (e, e ′ p). The continuum wave function describing the outgoing nucleon is made orthogonal to the relevant bound states using the Gram-Schmidt procedure. This procedure has the advantage of preserving the asymp-totic character of the(More)
A hysterographic study using the diluted dye technique (Urographin diluted to 15%) was carried out on 80 women to study the side effects that might result during the use of the T Cu 200 device in te 1st year of insertion. The hysterographic pictures showed the position and orientation of the device inside the uterine cavity and the side effects were(More)
Relativistic calculations for the quasifree electron scattering process (e, e ′ p) and the direct knockout contribution to (γ, p) reactions are presented. The spectroscopic factors determined from the former reaction are used to fix the magnitude of the knockout contribution to the (γ, p) reaction at 60 MeV. The results obtained for several nuclei indicate(More)
The relativistic amplitude for the direct knockout contribution to (γ, p) reactions on nuclei is reduced to a nonrelativistic form using an effective Pauli reduction scheme. The reduction is carried out to second order in the inverse nucleon mass. It is found that the interaction Hamiltonian appearing in the nonrelativistic amplitude has significant(More)
A relativistic non-local model for the inclusive photoproduction of η mesons from complex nuclei is introduced. The model is based on the dominance of the S 11 (1535) resonance. We compare the results of our calculations with the available data on inclusive cross sections for the nuclei C, Al and Cu. Assuming the resonance propagates freely in the nuclear(More)
A study was conducted using 32 women who had Copper T 200 IUDs inserted at the family planning clinic at Al-Ashar University Hospital in Cairo, Egypt. The study was conducted to determine the association between menstrual blood loss following IUD insertion, the shape and size of the uterine cavity, and the position and orientation of the IUD within the(More)
