Neuroimaging methods rely on models of neurovascular coupling that assume hemodynamic responses evolve seconds after changes in neural activity. However, emerging evidence reveals noncanonical BOLD (blood oxygen level dependent) responses that are delayed under stress and aberrant in neuropsychiatric conditions. To investigate BOLD coupling to resting-state fluctuations in neural activity, we simultaneously recorded EEG and fMRI in people with schizophrenia and psychiatrically unaffected participants.

Objective: Primary aim was to analyse dentoalveolar and skeletal effects induced by an anterior open bite (AOB) treatment protocol for intrusion of maxillary buccal segment. Secondary aim was to investigate whether a subsequent change occurred in hyoid position.
Materials And Methods: Study group included 28 non-growing subjects treated in academic setting for correction of AOB.
Sex-specific effects on the heart from combined exposure to simulated galactic cosmic radiation and hindlimb unloading.

Future long duration space missions will expose astronauts to higher doses of galactic cosmic radiation (GCR) than those experienced on the international space station. Recent studies have demonstrated astronauts may be at risk for cardiovascular complications due to increased radiation exposure and fluid shift from microgravity. However, there is a lack of direct evidence on how the cardiovascular system is affected by GCR and microgravity since no astronauts have been exposed to exploratory mission relevant GCR doses.

Introduction: Echinococcus is a common infection in an endemic country like Bhutan. Mediastinal echinococcosis is rare. Although presentation due to a mediastinal echinococcal cyst is variable according to the cyst's location, a reaction due to rupture of the cyst and simultaneous reaction to an administration of antibiotics such as ceftriaxone can cause a diagnostic challenge.

Department of Orthopedics and Traumatology, Faculty of Medicine, Ege University, Bornova, 35100, Izmir, Turkey.
Purpose: To evaluate the radiological and clinical outcomes in two patient groups: first, varus aligned medial meniscus posterior root tear (MMPRT) patients who underwent posteromedial open wedge high tibial osteotomy (PMOWHTO) and simultaneous root repair; second, patients with varus medial knee osteoarthritis without MMPRT who underwent PMOWHTO.
Methods: Patients had MMPRT repair concomitant with PMOWHTO and varus medial knee osteoarthritis without concomitant root tear patients who underwent PMOWHTO and were reviewed. Radiographic parameters, medial meniscus extrusion (MME) and Knee Society Scores [KSSs, including the following subscores: knee score (KS) and knee function score (KFS)] were evaluated.
