1. AVALIAÇÃO DENTOESQUELÉTICA E TEGUMENTAR DA RETRAÇÃO ANTERIOR EM DUAS FASES / Dentoskeletal and tegumentary assessment of the two- step retraction anterior
O objetivo do presente estudo consistiu em avaliar as alterações dentoesqueléticas e tegumentares promovidas pelo tratamento ortodôntico fixo com a retração anterior em duas fases, por meio de telerradiografias em norma lateral. Foram selecionados 14 pacientes com idade média de 14,6 anos que necessitavam de extrações dos quatro primeiros pré-molar

2. Stimulating neuroregeneration as a therapeutic drug approach for traumatic brain injury
Traumatic brain injury, a silent epidemic of modern societies, is a largely neglected area in drug development and no drug is currently available for the treatment of patients suffering from brain trauma. Despite this grim situation, much progress has been made over the last two decades in closely related medical indications, such as spinal cord injury, givi

3. Transient kinetics of the rapid shape change of unstirred human blood platelets stimulated with ADP.
Unstirred (isotropic) suspensions of human blood platelets stimulated with ADP in a stopped-flow laser turbidimeter exhibit a distinct extinction maximum during the course of the classical rapid conversion of initially smooth flat discoid cells to smaller-body spiny spheres. This implies the existence of a transient intermediate having a larger average light

4. Biomechanics of the movable pretarsal adhesive organ in ants and bees
Hymenoptera attach to smooth surfaces with a flexible pad, the arolium, between the claws. Here we investigate its movement in Asian weaver ants (Oecophylla smaragdina) and honeybees (Apis mellifera). When ants run upside down on a smooth surface, the arolium is unfolded and folded back with each step. Its extension is strictly coupled with the retr
