AbstractAbstract
[en] Radiographically, the size of the right ventricle of 54 heartworm-infected dogs was graded subjectively as normal, 1 +, 2 +, and 3 + and served to classify the dogs into groups A, B, C, and D. With M-mode echocardiograms, right ventricular enlargement ratios (RVE ratios) were determined for each dog by dividing the measured right ventricular internal diastolic dimension (RVIDd) by the expected RVIDd of a normal dog of the same body weight. The normal RVIDd relation to body weight was derived from 25 healthy heartworm-free control dogs. These two variables were linearly related with a correlation coefficient r2 = 0.59. Means and standard deviations of the RVE ratio were calculated for each group. Despite wide ranges and considerable overlap, the ratio was significantly different (t-test, p < 0.005) between groups with the exception of groups A and B, and C and D. The incidence of electrocardiographic signs of right ventricular hypertrophy was also determined for each group; it was 38% in group C and 62% in group D. From this data, it was concluded that M-mode echocardiography is a very sensitive technique for the documentation of right ventricular dilatation in heartworm-infected dogs, correlating with radiographic impressions of right ventricular enlargement.

AbstractAbstract
[en] Long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) are implicated in numerous kinds of cardiovascular diseases, and their vital role in regulating cardiac hypertrophy still needs to be explored. In this study, we demonstrated that lncRNA X-inactive specific transcript (XIST) was upregulated in hypertrophic cardiac of mice and phenylephrine (PE)-treated cardiomyocytes. Next, we observed that inhibition of XIST induced hypertrophic response of cardiomyocyte and overexpression of XIST attenuated cardiomyocyte hypertrophy induced by PE. Furthermore, through online predictive tools and functional experiments, we demonstrated that XIST and S100B were targets of miR-330-3p. XIST and miR-330-3p suppressed each other in a reciprocal way in cardiomyocytes. Additionally, XIST promoted S100B expression through harboring the complementary binding sites with miR-330-3p, eventually prevented cardiac hypertrophy. In conclusion, our findings revealed a novel molecular mechanism that XIST/miR-330-3p/S100B pathway modulates the progression of cardiomyocyte hypertrophy.

AbstractAbstract
[en] In this study, we have compared scintigraphic and echocardiographic data in order to investigate whether increased septal perfusion represents asymmetrical septal hypertrophy (ASH), which is a symptom followed in the scintigraphy of myocardial perfusion. The study consists of a total of 186 patients (120 females and 66 males with an average age of 59.45 ± 11.54 years) who had normal myocardial perfusion scintigraphy and echocardiography examinations. Statistical comparison of septal wall thickness measurements obtained from echocardiography and septal-to-lateral wall ratios (S/L ratio) was performed scintigraphically. Left ventricular mass values were obtained as both scintigraphic and echocardiographic data and their correlations were evaluated in order to assess the presence of left ventricular hypertrophy (LVH). In statistical analyses, the values of interventricular septal thickness in diastole (IVSd), left ventricle posterior wall thickness in diastole (LVPWd), left ventricle mass (LVM), and left ventricle mass index (LVMI) were found to be significantly higher in group 2 (S/L ratio >1) compared to group 1 (S/L ratio <1). In addition, S/L ratio is significantly correlated with echocardiographic IVSd, LVPWd, LVM, LVMI, and scintigraphic LVM (rest) values. Furthermore, echocardiographic LVM and LVMI values were significantly correlated with LVM and LVMI values obtained from scintigraphy. It should be known that increased S/L ratio that can be monitored during scintigraphic studies can be an indicator of septal hypertrophy and/or LVH, however, further examination and close follow-ups should be performed in necessary cases

AbstractAbstract
[en] Hypertrophic olivary degeneration resulting from lesions of the dento-rubro-olivary pathway, also called Guillain-Mollaret-triangle, has been described previously in a number of cases. Reports about bilateral hypertrophic olivary degeneration of the inferior olivary nuclei are very limited, and the magnetic resonance imaging findings of hypertrophic olivary degeneration in Wilson disease have not yet been described to the best of our knowledge. Herein, we present the first report of bilateral hypertrophic olivary degeneration diagnosed by magnetic resonance imaging in a patient suffering from Wilson disease.

AbstractAbstract
[en] Hypertrophic olivary degeneration is a trans-synaptic neuronal degeneration associated with hypertrophy of the inferior olivary nucleus due to a lesion in the triangle of Guillain-Mollaret. Familiarity with this entity on magnetic resonance imaging (MRI) is essential to avoid other erroneous ominous diagnoses. We present a case of bilateral hypertrophic olivary degeneration and discuss the etiopathogenesis and MRI findings in this entity. The contributory role of MR tractography in the diagnosis is also highlighted

AbstractAbstract
[en] Effects of thioacetamide (TAA) on the body weight, kidney weight and the total nucleic acids content of kidney of mouse were studied. TAA 1% and 2% solutions were injected intraperitoneally, twice with an interval of 24 hours in two different batches of male mice. In this way one batch received a total dose of 100 mg TAA/Kg body wt. while the other got a total dose of 200 mg TAA/Kg. Both the body as well as kidney weights decrease after TAA treatment. A total dose of 200 mg/Kg is a stronger inhibitor of growth as compared with that of 100 mg/Kg. The nucleic acids content show an increase after the drug treatment. The ribonucleic acid content of kidney increased from an average value of 4.30+0.14 mg/g kidney to 4.60+-0.22 mg/g kidney after 1% TAA treatment. The increase in 2% TAA treated mice is slightly more prominent. The deoxyribonucleic acid (DNA) content of kidney are likewise affected. After an initial increase in 1% TAA-treated animals, the DNA content gradually fall down to normal control values. Administration of 2% TAA solution causes an average increase of 21% i.e. from 1.93+-0.19 mg/g kidney wt to 2.26+-0.23 mg/g kidney wt. The size of cell, nucleus and nucleolus also increased after drug treatment, which mainly occurred during the first 24 hours of the post-treatment period

AbstractAbstract
[en] Olivary hypertrophy (OH) has recently been demonstrated by MRI, notably in cases of brain stem or cerebellar vascular lesion. Although histopathological studies of the changes with time in OH and MRI studies of the early phase have been performed, chronological studies, particularly long-term follow-up in relation to clinical manifestations, is lacking. The authors report such a case study. (orig.)

AbstractAbstract
[en] To compare the effectiveness of portal vein embolization (PVE) performed using gelfoam or a gelfoam-coil combination before major hepatic resection in patients with chronic liver disease. PVE using gelfoam or a gelfoam-coil combination was performed in 37 patients. From April 2003 to September 2007, PVE was performed using gelfoam (n = 17) and a gelfoam-coil combination (n = 20) to induce hypertrophy. Computed tomography volumetry was performed 2-4 weeks after PVE to assess the changes in liver volume. The mean percentage increase in future liver remnant volume was 23.7 +/- 23.7% in the gelfoam group and 36.7 +/- 18.5% in the gelfoam-coil group (p = 0.02). Recanalization was found in 15 gelfoam group patients and 8 gelfoam-coil group patients (p = 0.003). The mean tumor size increased from 4.5 +/- 2.9 cm before PVE to 5.0 +/- 3.5 cm after PVE in the gelfoam group and from 4.3 +/- 2.2 cm before PVE to 4.7 +/- 2.5 cm after PVE in the gelfoam-coil group (p = 0.80). The gelfoam-coil combination was more effective than gelfoam alone for induction of compensatory hypertrophy by PVE in patients with chronic liver disease.
