The structures made of myocardium running most often above the coronary arteries are called the muscle bridges. However there is a large number of descriptions of that phenomenon, the data are not homogenous. Some papers affirm the occurrence of the clinical implications of their existence. The studied material contained 100 adult human hearts, both sexes, 21 to 76 years of age, preserved in fo...

In cardiac magnetic resonance (CMR) imaging, a 3D high-resolution segmentation of the heart is essential for detailed description its anatomical structures. However, due to limit acquisition duration and respiratory/cardiac motion, stacks multi-slice 2D images are acquired in clinical routine. The these provides low-resolution representation anatomy, which may contain artefacts caused by motion...

The effect soft tissue movement of the shank had on knee joint moments during natural cadence walking was investigated in this study. This was examined by comparing knee moments determined from bone-anchored and surface mounted tracking targets. Six healthy adult subjects participated in this study. The largest difference (3 N m) occurred about the AP axis, with smaller differences of approxima...

BACKGROUND Changes of volume status can be readily inferred from variations in diameter of the inferior vena cava (IVC) measured by ultrasound. However the effect of IVC changes following acute blood loss are not fully established. In this study, three different approaches to measuring IVC variables were compared in healthy blood donors, as a model of acute volume depletion, in order to establi...

Background: The angle between femur neck and the long axis of shaft is known as which plays vital role in stability, control lateral balance, walking hip movements. main goal was to compare NSA intertrochanteric fracture immediately after surgical fixation using either Dynamic Hip Screw or Proximal Femoral Nail. In elderly among all fractures approximately half are out 50% unstable.Method: X-ra...

The comparative vertebral morphology of different chamaeleonid genera has been generally neglected and some aspects such as the comparative anatomy of the neck region remain poorly known. The atlas and axis of all chamaeleonid genera (Brookesia, Rieppeleon, Archaius, Rhampholeon, Nadzikambia, Bradypodion, Chamaeleo, Calumma, Furcifer, Kinyongia, and Trioceros) are studied here. Considerable mor...

The incidence of chronic stress is frequently related to the development of psychiatric disorders like depression. The hypothalamic-pituitary-adrenal (HPA) axis is a major physiological system that mediates the stress response. Tight HPA axis regulation through negative feedback mechanisms is essential for health and environmental adaptation. This feedback regulation acts in part through the gl...

Differences in behavioral roles, anatomical connectivity, and gene expression patterns in the dorsal, intermediate, and ventral regions of the hippocampus are well characterized. Relatively fewer studies have, however, focused on comparing the physiological properties of neurons located at different dorsoventral extents of the hippocampus. Recently, we reported that dorsal CA1 neurons are less ...

Rotation of the femoral component is an important aspect of knee arthroplasty, due to its effects on postsurgery knee kinematics and associated functional outcomes. It is still debated which method for establishing rotational alignment is preferable in orthopedic surgery. We compared force sensing based femoral component rotation with traditional anatomic landmark methods to investigate which m...
