Mri Study

Early changes of lung function and structure were studied in the presence of an elastase-induced model of emphysema in 35 Sprague-Dawley rats at mild (5 U/100 g) and moderate (10 U/100 g) severities. Lung ventilation was measured on a regional basis (at a planar resolution of 3.2 mm) by hyperpolarized 3He MRI at 5 and 10 wk after model induction. Subsequent to imaging, average alveolar diameter was measured from histological slices taken from the centers of each lobe. Changes of mean fractional ventilation, mean linear intercept, and intrasubject heterogeneity of ventilation were studied during disease progression. Mean fractional ventilation was significantly different between healthy controls (0.23 ± 0.04) and emphysematous animals at both time points in the 10-unit group (0.06 ± 0.02 and 0.12 ± 0.05, respectively). Changes in average alveolar diameter were not statistically observable until the 10th wk between healthy (37 ± 10 μm) and emphysematous rats (73 ± 25 and 95 ± 31 μm, for 5 and 10 units, respectively). Assessment of function-structure correlation suggested that the majority of the decline in fractional ventilation occurred in the first 5 wk, while enlargement of alveolar diameters appeared primarily between the 5th and 10th wk. A thresholding metric, based on the 20th percentile of fractional ventilation over the entire lung, was utilized to detect the onset of the disease with confidence, independent of whether the regional ventilation measurements were normalized with respect to the delivered tidal volume and estimated functional residual capacity of each individual rat.

Splanchnic Hypoperfusion

Splanchnic hypoperfusion as reflected by gastric intramucosal acidosis has been recognized as an important determinant of outcome in shock. A comprehensive splanchnic hypoperfusion-ischemia reperfusion (IRP) protocol was evaluated against conventional shock management protocols in critical trauma patients. The study was a prospective randomized trial comparing three therapeutic approaches to hypoperfusion after severe trauma in 151 trauma patients admitted to the intensive care unit. Group 1 patients received hemodynamic support based on conventional indicators of hypoperfusion. In group 2, resuscitation was further guided by gastric tonometry-derived estimates of splanchnic hypoperfusion and included more invasive hemodynamic monitoring and additional administration of colloid or crystalloid solutions, or inotropic support. Group 3 patients additionally received therapies specifically aimed at optimizing splanchnic perfusion and minimizing oxidant-mediated damage from reperfusion. The three groups were similar based on age, Injury Severity Score, and Acute Physiology and Chronic Health Evaluation II Scores. There were no statistically significant differences in mortality rates, organ dysfunction, ventilator days, or length of stay between any of the interventions. Techniques of optimization of splanchnic perfusion and minimization of oxidant-mediated reperfusion injury evaluated in this study were not advantageous relative to standard resuscitation measures guided by conventional or tonometric measures of hypoperfusion in the therapy of occult and clinical shock in trauma patients.

Abstract We consider smooth representations of the unit group G = A × G=\mathcal{A}^{\times} of a finite-dimensional split basic algebra 𝒜 over a non-Archimedean local field. In particular, we prove a version of Gutkin’s conjecture, namely, we prove that every irreducible smooth representation of 𝐺 is compactly induced by a one-dimensional representation of the unit group of some subalgebra of 𝒜. We also discuss admissibility and unitarisability of smooth representations of 𝐺.

The Impact

In this paper, the origins and characteristics of the 102 current UK universities are briefly traced and the outcomes of recent assessments of research quality are summarized for all universities and for the 69 subject units within which assessment was made. The quality of research in a subject unit, group of subject units or complete institution is measured by a weighted average score based on a peer rating of submitted subject units from each university and the numerical values obtained are described within the limitations of the methodology developed. The authors consider the scores in terms of the characteristics of each university and the broad subject areas, science, engineering, social sciences and humanities. They then discuss the industrial link with research in terms of recent government policy inputs, university research outcomes and the impact of market forces on universities from diminishing patterns of some income streams.

Background: We aimed to evaluate the safety and efficacy of 50-unit dose against 100-unit dose of intracavernosal injection (ICI) of AbobotulinumtoxinA (BTX-A) (Masport®) in patients with vascular erectile dysfunction (ED) resistant to first-line therapies, including phosphodiesterase type 5 inhibitors (PDE5I). Methods: In this double-blind randomized controlled trial (RCT), 40 patients with ED resistant to PDE5I were randomly divided into two groups: ICI of a single dose of Masport® 50 units and single dose of 100 units. Peak systolic velocity (PSV) confirmed arterial insufficiency vascular disorder. For all patients, IIEF (International Index of Erectile Function), SHIM (Sexual Health Inventory for Men), and EHS (Erection Hardness Score) questionnaires were completed. Six weeks after the treatment, the subjects were re-examined. Results: Our results showed an acceptable clinical efficacy and safety of ICI of Masport® six weeks after injection. No systemic complications in patients were seen. Three patients complained of brief penile pain shortly after injection, but there were no other local complications. The increase in mean PSV in the 100-unit group due to treatment was significant (P-value < 0.0001). Also, there was a significant difference between the two groups of 50- and 100-unit (P-value < 0.0001). In addition, the increase in mean IIEF-EF, SHIM score, and EHS due to treatment was significant between the two groups. For the 100-unit group, P-value < 0.0001 and the difference between the two groups was also significant (P-value < 0.0001), which indicated a better response to treatment in the 100-unit group. The mean increase of IIEF score (EF domain) was 4.3 (mean IIEF: 9.4 and 13.7 after and before, respectively) in the 100-unit group and (mean IIEF: 8.1 and 9.1 after and before, respectively) in the 50-unit group. Conclusions: The results of this study showed that ICI of AbobotulinumtoxinA, especially at a dose of 100 units, in patients with refractory vasculogenic ED is safe and effective in improving sexual function and ultrasound indices.
