Echogenicity Echogenicity or echogeneity is the ability to bounce an echo, e.g. return the signal in ultrasound examinations. In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves. Tissues that have higher echogenicity are called hyperechogenic and are usually represented with lighter colors on images in medical ultrasonography. In contrast, tissues with lower echogenicity are called hypoechogenic and are usually represented with darker colors. Are

- The most characteristic ultrasonographic feature of an angiomyolipoma is its echogenicity; however, angiomyolipomas may also cause acoustic shadowing. The echogenic appearance of the tumor is thought to be related to its fat content and the presence of multiple tissue interfaces within it.

- Echocardiography (ultrasound of the heart, echocardiogram) A test using ultrasound to study the heart's position, motion of the walls, and valves. This test can be used in the diagnosis of a number of heart conditions including an enlarged heart, valve disorders, weakened heart muscle and blood clots inside the heart.

- Small echogenic foci in theovaries are most frequently due to hemosiderin or calcification. A few small echogenic foci in theovaries are associated with benign histologic changes and do not appear to be reliable indicators ofendosalpingiosis or endometriosis. Key words: calcification; hemosiderin; ovary; sonography.f echogenic foci were present in either normal ovary on the preoperativescan, the removed ovary was scanned in a saline bath, and the surface was marked with india ink overan echogenic focus. Histologic sections were then obtained at the marked site. Results. Echogenic fociwere detected in 23 ovaries of 16 women.

echocardiography Echocardiography is a diagnostic test that uses ultrasound waves to create an image of the heart muscle. Ultrasound waves that rebound or echo off the heart can show the size, shape, and movement of the heart's valves and chambers as well as the flow of blood through the heart. Echocardiography may show such abnormalities as poorly functioning heart valves or damage to the heart tissue from a past heart attack.

Viral Capsids and Envelopes: Structure and Function Where no envelope is present, this function is carried out by the outer capsid proteins. In general, nonenveloped viruses are more stable and can survive much longer in the environment. Capsids and envelopes determine the method of viral entry into and exit from host cells.

TRIGENICS FUNCTIONAL MUSCLE NEUROLOGYADVANCED TREATMENT AND TRAINING PRINCIPLES IN MUSCLE NEUROLOGY What is Trigenics®? Trigenics is an advanced treatment method for neuro-musculoskeletal and soft tissue conditions. The discipline is outcomes based and delivers immediate and sustained improvements to strength, performance, range of motion and the relief of pain. The pronounced impact of Trigenics is realised through the synergistic effect of resistive exercise neurology, muscle nerve sensor stimulation, and diaphragmic parasympathetic breathing.

- The calcifying epithelial odontogenic tumor (CEOT), or Pindborg tumor, is a benign infiltrative odontogenic tumor that is one of the rarest. It is named after Jens Pindborg, the Danish oral pathologist. It is most often found in the mandibular molar/premolar region, but 33% of cases are found in the maxilla.wo thirds of the cases occur in the anterior maxilla, one third occur in the anterior mandible, and it is never found posterior to the premolars. Two thirds of the cases occur in females, and two thirds of the cases are associated with an impacted tooth (usually the cuspid).
