The following new gregarine taxa are described from larvae of flour beetles (Coleoptera: Tenebrionidae): Awrygregarina billmani, n. gen., n. sp., from Tribolium brevicornis; Gregarina cloptoni, n. sp., from Tribolium freemani; Gregarina confusa, n. sp., from Tribolilum confusum; and Gregarina palori, n. sp., from Palorus subdepressus. In addition, the description of Gregarina minuta Ishii, 1914...

the effect of axial deformation of shell particles on the dynamic instability (flutter) of cantilevered cylindrical shells made of functionally graded materials (fgm) under an end axial follower force is addressed. to this end, at first, results for free vibration of fgm cylindrical shells were verified with previous outcomes and they were in very good agreement. then, the effect of axial defor...

Prostate cancer is the second most common cause of cancer death in men in the United States. The most common sites of metastasis include the bone, lymph nodes, lung, liver, pleura, and adrenal glands, whereas metastatic prostate cancer involving the gastrointestinal tract has been rarely reported. A 64-year-old African-American man with a history of prostate cancer presented with anemia. He rep...

BACKGROUND Echocardiographic evaluation of left ventricular (LV) strain and strain rate (SR) by 2D speckle tracking may be useful tools to assess chronic thromboembolic pulmonary hypertension (CTEPH) severity as well as response to successful pulmonary thromboendarterectomy (PTE). METHODS We evaluated 30 patients with CTEPH before and after PTE using 2D speckle tracking measurements of LV rad...

purpose: to report bilateral terrien’s marginal degeneration, circumferential peripheral corneal ectasia and posterior polymorphous dystrophy in a patient with rheumatoid arthritis. case report: a 24-year-old male patient, who was known case of rheumatoid arthritis from 8 years before, presented with decreased vision since four years ago. comprehensive ophthalmic eye exami-nation revealed bilat...

Background Estimation of strain parameters from cine acquisitions, such as balanced steady state free precession (b-SSFP) is advantageous, as it would obviate the need for acquisition of additional strain sequences reducing scanning time and making strain more accessible to clinicians. 2D strain derived from feature-tracking is now commercially available. The GlasgowHeart cine-strain method is ...

Antibodies specific for measles virus could redistribute ("cap") virus antigens on infected HeLa cells as shown by transmission and scanning electron microscopy. Using an indirect immunoperoxidase technique, infected cells showed diffuse, circumferential distribution of virus antigens over the cell surface when mixed with antibody at 4 C. At 37 C, virus-coated microvilli concentrated on one pol...

Sixteen acromegalic patients underwent echocardiography, phonocardiography, stress electrocardiography with Thallium perfusion scanning and gated radioisotope left ventricular angiocardiograms. Abnormalities consisting of increased echo left ventricular mass index, low velocity of circumferential fiber shortening or elevated pre-ejection period to left ventricular ejection time ratio were found...

Circumferential bands of microtubules (MT) support the discoid shape of resting platelets and participate with the contractile apparatus in shape change and internal contraction following activation. Elucidation of interactions between the circumferential coils and proteins of the stable and contractile cytoskeleton is essential for understanding MT function in platelet physiology. A previous i...

In cylindrical continua, hoop stresses are induced due to the circumferential failure. This mainly happens when the cylinder is subjected to mechanical loads which vary in the circumferential directions. On the other hand, radial stress is stress in the direction of or opposite to the central axis of a cylindrical body. In the present study, the influence of curvilinear anisotropy on the radial...
