Background. Rocabado’s hyoid triangle is the only cephalometric parameter that can assess the effects of orthodontic treatment on tongue posture. Aim. To evaluate the restoration of tongue posture and function by conducting a cephalometric assessment of the hyoid triangle before and after rapid maxillary expansion. Methods. Sixtyfour healthy patients aged 6-11 years with skeletal class II maloc...
Chronic myelogenous leukemia (CML) is a myeloproliferative disorder characterized at the molecular level by the expression of Bcr-abl, a 210-kDa fusion protein with deregulated tyrosine kinase activity. Encouraged by the clinical validation of Bcr-abl as the target for the treatment of CML by imatinib, we sought to identify pharmacological agents that could target this kinase by a distinct mech...
Omnivorous Heteroptera constitute an important component of predatory guilds with high potential for biological control. Understanding the relative effects of plant feeding on the suppression of prey by omnivores could be an important element for improving biological control strategies. In the current paper, the effects of different plant food sources on the predation rate of the omnivorous pre...
Starting from the new background field formalism for T > 0, with nonperturbative (NP) background given as gauge invariant fiel corre-lators, new perturbation theory and diagram technic is introduced. Confined and deconfined phases are explicitly described and critical temperature T c is expressed in terms of the scale anomaly term. Resulting numerical estimates of T c agree well with lattice da...
We summarize the work done by the European working group on Higgs Particles for the Workshop " Physics with e + e − Linear Colliders " , Annecy–Gran Sasso– Hamburg, Feb.–Sept. 1995. The main focus will be on the physics possibilities at a second phase e + e − linear collider with a center of mass energy of ∼ 1.5 TeV.
where e, e label the helicity states and k is the momentum transfer. In a naive wave function picture G1(0) can be interpreted as the fraction of the nucleon spin carried by the quarks. Experimental determinations lead to an unexpectedly small value of G1(0), calling for a theoretical explanation in the context of a nonperturbative study in QCD. G1(0) can be extracted from the nucleon matrix el...
