Preoperative evaluation of peripheral nerve injuries: What is the place for ultrasound?

2016

OBJECTIVE The purpose of this study was to evaluate the usefulness of ultrasound in the preoperative workup of peripheral nerve lesions and illustrate how nerve ultrasonography can be integrated in routine clinical and neurophysiological evaluation and in the management of focal peripheral nerve injuries. The diagnostic role and therapeutic implications of ultrasonography for different neuropathies are described. METHODS The authors analyzed the use of ultrasound in 119 entrapment, tumoral, posttraumatic, or postsurgical nerve injuries of limbs evaluated in 108 patients during 2013 and 2014. All patients were candidates for surgery, and in all cases the evaluation included clinical examina…

Studies on vinblastine-induced autophagocytosis in mouse liver. III. A quantitative study.

1982

The microtubule inhibitor vinblastine (25 mg/kg, i.p.) induces autophagocytosis in mouse hepatocytes. The formation of autophagic vacuoles, their contents, and other cellular changes after vinblastine injection in hepatocytes, were studied by light and electron microscopic morphometric analysis. The volume density of autophagic vacuoles increased significantly during the experimental period (24 h). This increase was due to the significant increase in their number, which was approximately 5-fold 4 h, 12 h and 24 h after vinblastine injection. The mean volume of the autophagic vacuoles increased significantly 1 h after vinblastine injection, at which time the formation of new autophagic vacuo…

Effect of Intraperitoneal Sterile Urine Injection on Abdominal Myoelectrical Activity in the Spinal Rat Model

1991

The abdominal muscle reflex contractions in response to intraperitoneal injection of homologous sterile urine and acid, alkaline, hypo- and hyperosmolar solutions are studied in an acute spinal rat model by conventional and integrated electromyographic techniques. Intraperitoneal injection of homologous sterile urine causes a powerful and almost immediate abdominal muscle contracture of relative short duration. This response seems not to be related to urine pH or osmolarity, since only when solutions with extreme variations in these parameters are injected intraperitoneally are significant abdominal muscle contractions observed.

Sulpiride has an antiaggressive effect in mice without markedly depressing motor activity

1991

The atypical neuroleptic, sulpiride is a selective D2 antagonist, having a preferential action on mesolimbic regions. The effects of acute and chronic treatment with sulpiride on aggressive behaviour in male mice were studied using an ethologically based analysis. It was hypothesized that sulpiride would diminish "threat" and "attack" but would not produce marked "immobility", because of the mesolimbic effect referred to above. Isolated albino male mice (experimental animals) were confronted by "standard opponents". Acutely-treated experimental animals received an intraperitoneal injection of sulpiride (20, 50 or 100 mg/kg) 30 min before testing. Chronically-treated animals received sulpiri…

EFFECTS OF 4-AMINOPYRIDINE ON ACETYLCHOLINE OUTPUT FROM THE CEREBRAL CORTEX OF THE RAT in vivo

1982

Abstract 1 The effects of 4-aminopyridine (4AP) on the output of acetylcholine (ACh) from the cerebral cortex were investigated in unanaesthetized freely moving rats and in anaesthetized rats by means of the `cup technique'. ACh was determined by bioassay on the dorsal muscle of the leech. 2 In unanaesthetized rats intraperitoneal injection of 4AP (3 mg/kg) had no effect on the cortical output of ACh. 3 After injection of morphine (10 mg/kg s.c.), which depressed the spontaneous output of ACh, 4AP increased the cortical output to a level significantly higher than that determined before morphine injection. 4 In rats anaesthetized with either urethane or pentobarbitone, drugs known to decreas…

Vancomycin pharmacokinetics during continuous ambulatory peritoneal dialysis in patients with peritonitis.

2011

The aim of this study was to define a two-compartments pharmacokinetic model and to estimate the pharmacokinetic parameters of IP administered vancomycin in patients with continuous ambulatory peritoneal dialysis (CAPD) associated peritonitis. Ten patients with peritoneal dialysis treatment and peritonitis were prospectively enrolled in the study. The empiric treatment is: vancomycin 2 g every 5-7 days and ceftazidime 1500 mg per exchange, once daily. Pharmacokinetic modeling and parameter calculations were carried out using the nonlinear regression. The mean peritoneal concentration 10 min after the first peritoneal exchange of vancomycin free dialysis liquid was 9.5±7.3 μg/ml, showing tha…

Shelled-Molluscs Fauna at Abrolhos Bank (Brazil): Assessment of Both Total Species Richness and the Completed Distribution of Species Frequencies by …

2020

Numerous anthropogenic threats to the exceptionally rich coral-reef ecosystem at Abrolhos Bank (Brazil) arguably require implementing drastic conservation policy and meanwhile, urge for the prior detailed assessment of species richness and the species distribution across the Bank. Due to their unavoidable incompleteness, the already implemented “Rapid Assessment Surveys” at Abrolhos Bank deserve being completed, at least numerically, by implementing an appropriate extrapolation procedure, to avoid serious bias precisely due to ignoring both the number and the frequency distribution of those species still remaining undetected after Rapid Assessment Surveys. Complying with this concern, I rep…

Skin in the game: Self-funding and reward crowdfunding success

2022

Abstract This article focuses on entrepreneurs’ self-funding behavior in the reward crowdfunding context and its relation to crowdfunding success. Theoretically anchoring our discussion in signaling theory, we argue that self-funding sends similar information to that conveyed by quick-fix bootstrapping efforts. Accordingly, we hypothesize that self-funding behavior is positively associated with crowdfunding success as it can help alleviate uncertainties around a fundraiser’s intent and quality as perceived by prospective backers. To show this, we use a sample of 1,583 campaigns collected from Zhongchou, the largest Chinese reward-based crowdfunding platform, to test our hypotheses. Our resu…
