Abstract:

Cytosolic Ca2+ has been postulated to regulate smooth muscle hypertrophy and growth factor production. Consistent with this hypothesis we report that the Ca2+ channel antagonists verapamil and diltiazem prevent bladder and neuronal growth in rats in response to 3 wk of urethral obstruction. Ca2+ channel blockers prevented 30-45% of the increase in bladder weight, protein, and DNA content found in obstructed animals. Similarly, these drugs produced a 15-27% reduction in area profiles for retrogradely labeled (Fluoro-Gold) motoneurons in the major pelvic ganglia and afferents in the L6-S1 dorsal

Abstract:

We examined the mechanisms underlying the abrupt onset of the focal infarction in disseminated selective neuronal necrosis (DSNN) after temporary ischemia. Stroke-positive animals were selected according to their stroke-index score during the first 10 minutes after left carotid occlusion performed twice at a 5-hour interval. The animals were euthanized at various times after the second ischemia. Light- and electron-microscopical studies were performed chronologically on the coronal-cut surface of the cerebral cortex at the chiasmatic level, where focal infarction evolved in the maturing DSNN.

There was no correlation between sphincter size and anal manometry. The external sphincter muscle was thicker and the cross-sectional area larger in patients with obstructed defecation than in healthy controls (p < 0.05). Two patients with sphincter spas

Following the release of short periods of unilateral ureteral obstruction (UUO), glomerular filtration rate (GFR) recovers by time. However, research in experimental animal models has demonstrated the presence of an ongoing element of renal interstitial fibrosis a few weeks following UUO reversal. Interstitial fibrosis can cause deterioration in GFR, and it is not known whether it leads to an ongoing slow deterioration in other renal functions despite the apparent initial recovery postreversal. To investigate this, rats underwent a 72-h reversible UUO. Renal functions of nonobstructed and prev

Human-wolf conflict has been one of the major issues in the Himalayan region of Nepal. It has obstructed the sustainable management initiatives in Annapurna Conservation Area. The aim of this study is to assess the status of human-wolf conflict, conservation threats to wolf and people’s perception towards this endangered carnivore. Questionnaire survey was conducted in different wards of three rural municipalities (RM) of the Upper Mustang. Similarly, key informants were interviewed followed by several discussions with stakeholders. The results indicate “wolf’s preference for domestic livestoc

Abstract:

The characterization of forested landscapes is frequently required in civil engineering practice. In this study, some spatial analysis techniques are presented that might be employed with Landsat TM data to analyze forest structure characteristics. A case study is presented wherein fractal dimensions (FDs), along with a simple spatial autocorrelation technique (Moran’sI), were related to stand density parameters of the Oakmulgee National Forest located in the southeastern United States (Alabama). The results indicate that when smaller trees do not dominate the landscape (<50%), forested are

A preoccupation with the US and narrow notions of area studies have obstructed scholarship on the diversity of bilateral relations and the emergence of the Northeast Asian regional community. During the Cold War, for example, this meant that Sino-Japanese and Russo-Japanese ties were neglected. In the 1990s the problem became more acute because many bilateral ties intensified and acquired new dimensions. There was an outpouring of new primary and secondary sources within the region, while rapidly evolving conditions made updating of insights imperative. The gap keeps widening between the claim

AbstractOn the one hand, we prove that the Clifford torus in {\mathbb{C}^{2}} is unstable for Lagrangian mean curvature flow under arbitrarily small Hamiltonian perturbations, even though it is Hamiltonian F-stable and locally area minimising under Hamiltonian variations. On the other hand, we show that the Clifford torus is rigid: it is locally unique as a self-shrinker for mean curvature flow, despite having infinitesimal deformations which do not arise from rigid motions. The proofs rely on analysing higher order phenomena: specifically, showing that the Clifford torus is not a local entrop

Chronic inflammation has an important role in the development and progression of most fibrotic diseases, for which no effective treatments exist. Tubulointerstitial fibrosis (TF) is characterized by irreversible deposition of fibrous tissue in chronic kidney diseases. Prolonged injurious stimuli and chronic inflammation regulate downstream events that lead to TF. In recent years, interleukin-17 (IL-17) has been strongly linked to organ fibrosis. However, the role of IL-17 receptor signaling in TF is an active area of debate. Using the unilateral ureteral obstruction (UUO) mouse model of TF, we

Because %RFLV showed marginal tolerability for curative hepatectomy and %RLV was very low, we opted for transarterial chemoembolization of segment IV and the right lobe containing the tumor as an app
