background: as various implant geometries present different biomechanical behaviors, the purpose of this work was to study stress distribution around tapered and cylindrical threaded implant geometries using three-dimensional finite element stress analysis.     methods: seven implant models were constructed using the cad system. after digitized models of mandibular section, the crowns were crea...

while blunt trauma of the head and neck are a common pattern of injury, significant problems related to the prompt diagnosis and optimal management of traumatic artery injuries have been reported in the literature. while patients with major artery injuries might develop hemorrhagic shock very rapidly, patients with blunt cerebrovascular injuries (bcvi) can present asymptomatic, but complication...

background and aim: this study investigated whether objective temporal processing paradigms including voice-onset-time, speech-in-noise, and amplitude modulated-broad-band noise (am-bbn) are sensitive to disrupted temporal processing in elderly listeners with normal hearing (age-related-temporal processing deficit). methods: we evaluated 15 adults aged 64–80 years using behavioural measures of ...

Developing Cortical Interneuronsin Schizophrenia The elusive human brain is much like the unattainable sun, and there no directly feasible approach to understand how disturbed during development of schizophrenia. As shimmering sun's reflection in water, organoid provides an accessible bridge explore mysteries brain. In article number 2300455, Peiyan Ni, Chuqing Zhou, Sangmi Chung, co-workers co...
