Does exercise influence burn-induced inflammation: A cross-over randomised controlled feasibility trial.

Background: Burn injuries trigger a greater and more persistent inflammatory response than other trauma cases. Exercise has been shown to positively influence inflammation in healthy and diseased populations, however little is known about the latent effect of exercise on chronic inflammation in burn injured patients. The aims of the pilot study were to assess the feasibility of implementing a long duration exercise training program, in burn injured individuals including learnings associated with conducting a clinical trial in COVID-19 pandemic.

An objective measure for the assessment and management of fluid shifts in acute major burns.

Background: Major burns are life threatening. Fluid resuscitation is required for survival to maintain intravascular volumes and prevent hypovolemic shock. Bioimpedance spectroscopy (BIS) has been recognised as a potential method of monitoring fluid shifts after burn and in other disease states.

Monitoring wound healing in minor burns-A novel approach.

Assessment of minor burn wound closure is predominately determined by visual inspection and clinical specialist assessment, which remains largely a subjective analysis and results may vary depending on the clinician's experience. Bioimpedance spectroscopy (BIS) is an instrument that has a demonstrated ability to objectively monitor the wound healing process in various patient populations but has not yet been used in acute burn wounds. The aim of the pilot study was to examine whether the BIS technique is a valid measure of wound healing.

Bioimpedance spectroscopy: A technique to monitor interventions for swelling in minor burns.

The control of edema in burn injured patients is a priority as it can impede the wound healing process. Bioimpedance spectroscopy (BIS) has been identified as a method of swelling assessment that has merit after burns. The aim of this study was to examine the reliability and validity of BIS in the measurement of localised burn wound edema across (1) different dressing conditions (no dressing, non silver and silver dressings) and (2) three electrode positions.

Addressing the Barriers to Bioimpedance Spectroscopy Use in Major Burns: Alternate Electrode Placement.

Bioimpedance spectroscopy (BIS) is a method used to assess body composition and fluid distribution. As a technology for measurement of fluid shifts during acute burn resuscitation, there are potential barriers to its use due to the location of wounds. This study aimed to determine whether alternate electrode positions were a suitable alternative compared to standardized (manufacturer) positions in moderate to large size burns for the measurement of BIS resistance and fluid changes.

Nanocrystalline silver dressings significantly influence bioimpedance spectroscopy measurements of fluid volumes in burns patients.

Bioimpedance spectroscopy (BIS) is a tool utilized in health care to investigate body composition and fluid distribution. Limited research has addressed the clinical use of BIS in burns. This study aimed to examine the effects of silver dressings on BIS measurements in burns patients.

Alternate electrode placement for whole body and segmental bioimpedance spectroscopy.

Bioimpedance spectroscopy (BIS) is frequently used to monitor body fluid and body composition in healthy and clinical populations. BIS guidelines state that there should be no skin lesions at the site of electrodes, and if lesions are present, electrode positions should be changed. However, alternate electrode positions are yet to be reported.

The risk of upper tract recurrence following cystectomy in patients with transitional cell carcinoma involving the distal ureter.

Purpose: Risk factors for the development of an upper urinary tract transitional cell carcinoma following radical cystectomy are identified.

Materials And Methods: The records of 430 patients who underwent cystectomy for transitional cell carcinoma of the bladder between 1981 and 1988 were retrospectively reviewed.

Results: Upper tract tumors developed in 11 patients (2.

Circular ruffle formation and closure lead to macropinocytosis in hepatocyte growth factor/scatter factor-treated cells.

Treatment with hepatocyte growth factor/scatter factor (HGF/SF) rapidly induced the formation of conspicuous circular ruffles on the apical surfaces of two kidney cell lines, MDCK and PtK2. The ruffles were found to contain significant amounts of F-actin and myosin as judged by immunofluorescence microscopy. Time-lapse photomicroscopy demonstrated that the ruffles constrict, closing over, and were followed by the formation of phase bright structures.

Computed tomography of primary transitional cell carcinoma of upper urinary tracts.

Preoperative computed tomography (CT) was utilized to evaluate 20 patients with primary transitional cell carcinoma of the upper urinary tracts. Of the 20 patients, 18 (90%) had CT visualization of the tumor as either a discrete mass or local ureteral and/or renal pelvic wall thickening; 2 (10%) had false-negative examinations. Seven of the 20 patients (35%) had CT evidence of tumor extension demonstrated by frank tumor invasion beyond the urothelium or by perirenal pelvic and/or periureteral fat streaks.

Enhancement of thymic recovery after cyclosporine by recombinant human growth hormone and insulin-like growth factor I.

Correlation of thymic changes with the development of CsA-associated syngeneic graft-versus-host disease (sGVHD) suggested that the development of tolerance depends on the prompt regeneration of the thymus after stopping CsA. Accordingly, we have tested recombinant human growth hormone (rhGH) and recombinant human insulin-like growth factor I (rhIGF-1) to determine if they accelerate reconstitution of the rat thymus after CsA-induced involution. After 14 days of CsA, the thymus has marked medullary involution but normally recovers fully in 6 weeks.

Paraganglioma of urethra.

Paraganglioma of the urethra is a rare tumor; only 4 cases have been reported previously. We report a fifth case of urethral paraganglioma and review the literature.

Prognostic factors in patients with primary transitional cell carcinoma of the upper urinary tract.

A total of 50 patients with primary transitional cell carcinoma of the upper urinary tract underwent deoxyribonucleic acid ploidy characterization by flow cytometric analysis of paraffin embedded specimens. The primary tumor was diploid in 29 patients (58%) and aneuploid in 21 (42%). Aneuploidy was identified more frequently in grade 3 than in grades 1 and 2 neoplasms (p = 0.

Flow cytometric analysis of primary and metastatic bladder cancer.

A total of 22 patients with high grade P2-4N+ transitional cell carcinoma of the bladder underwent flow cytometric analysis of nuclei obtained from paraffin embedded specimens from the primary (bladder) and metastatic (lymph node) sites. Tumor heterogeneity was defined as polyclonal aneuploidy of the primary tumor (not identified in the population studied) or as a difference in the deoxyribonucleic acid index of the primary and metastatic sites of 0.20 or more (8 patients).

The stereospecificity of the reduction of nitrate by reduced nicotinamide-adenine dinucleotides catalysed by Candida utilis preparations.

The reduction of nitrate by reduced nicotinamide-adenine dinucleotides, catalysed by extract of Candida utilis, exhibits an apparent high degree of stereospecificity for the 'B' methylene hydrogen atom of NADPH and mixed stereospecificity for the methylene hydrogen atoms of NADH. Purified nitrate reductase, on the other hand, exhibits 'A' stereospecificity for NADH and NADPH. The apparent switch of stereospecificity from the 'B' to the 'A' side of NADPH, which occurs after purification of the enzyme, is partly explained by the fact that in crude extracts nitrate is reduced completely to ammonia.

The control of the production of lactate and ethanol by higher plants.

Factors controlling the production of ethanol and lactate have been examined using cell free extracts prepared from pea seeds (Pisum sativum var Alaska) and parsnip roots (Pastinaca sativa). The result suggest that under aerobic conditions pyruvate decarboxylase is inactive. With the onset of anaerobiosis glycolysis leads to an accumulation of lactate with a corresponding fall in pH.

1. The stereospecificity of 20 enzymes from plants is reported. 2.
