Chaenothecopsis schefflerae (Ascomycota: Mycocaliciales): a widespread fungus on semi-hardened exudates of endemic New Zealand Araliaceae
2017
Ascomycetes specialised to live on hardened plant exudates occur worldwide, but the number of species so far described is relatively small (c.30). Particularly within the genus Chaenothecopsis (Ascomycota:Mycocaliciales), many species produce their ascomata on hardened but still relatively fresh outpourings of conifer resin or angiosperm exudate. Temperate rainforests of New Zealand provide habitat for several endemic Chaenothecopsis species, including Chaenothecopsis schefflerae, which was previously known from a single sample collected from the exudate of Schefflera digitata (Araliaceae) in the early 1980s. Here we show that C.schefflerae is neither lost nor very rare, but occurs sporadic…
Small pelagic fish in the new millennium: A bottom-up view of global research effort
2021
The present review is an outcome of discussions at the ICES-PICES Symposium on Drivers of Dynamics of Small Pelagic Fish convened in Victoria, B.C., Canada in spring 2017.-- This review is a first contribution of a new international Working Group on Small Pelagic Fish started jointly by ICES (WGSPF) and PICES (WG43) to continue world-wide collaboration to advance knowledge on the drivers of populations of SPF.

2017
Inocybe castaneicolor sp. nov., collected in Sicily (Italy), is introduced with full description, line drawings, and color photographs. Its novelty is supported by both its morphology and molecular phylogenetic analysis. It is characterized by its castaneous brown pileus with an evident umbo and sloped margin, subfusiform cystidia and smooth subamygdaliformis to subnavicular spores. Comparison of I. castaneicolor with similar species is also provided.
Electromyographic Effect of Using Different Attentional Foci During the Front Plank Exercise
2018
Objective The aim of this cross-sectional study was to examine whether an internal focus on different core muscles during the isometric prone plank exercise increased muscle activity. Design Twenty university students performed the following five different conditions: regular prone plank (external focus) and prone plank with an internal focus on different muscles. Surface electromyography signals were recorded for the upper rectus abdominis, lower rectus abdominis, external oblique, and lumbar erector spinae. Results For the upper rectus abdominis, an internal focus on using any muscle increased activity. For the lower rectus abdominis, internal focus on any muscle except the lumbar erector…
Treatment of painful radiculopathies with capsaicin 8% cutaneous patch.
2017
The treatment of neuropathic pain due to low-back (lumbosacral) radiculopathies, a common source of neuropathic pain, is challenging and often requires a multimodal therapeutic approach. The capsaicin 8% patch is the first topical analgesic licensed for peripheral neuropathic pain. To evaluate this treatment, a subset of patients with painful radiculopathy (lumbar and cervical, including ventral and dorsal rami) enrolled into the multicenter, non-interventional QUEPP study (QutenzaOf the 1044 study participants, 50 were diagnosed with painful radiculopathy as only peripheral neuropathic pain syndrome and were eligible for evaluation. Patients received a single treatment (visit 1) with follo…
The long-term effects of rally driving on spinal pathology
2000
Abstract Objectives. To investigate the consequences of rally driving on lumbar degenerative changes. Background. Vehicular driving is suspected to accelerate disc degeneration through whole-body vibration, leading to back problems. However, in an earlier well-controlled study of lumbar MRI findings in monozygotic twins, significant effects of lifetime driving on disc degeneration were not demonstrated. Another study of machine operators found only long-term exposure to vibration on unsprung seats led to a reduction in disc height. Design. Case-control study comparing rally drivers with population sample. Methods. Eighteen top rally drivers and co-drivers, mean age 43 yrs (SD, 10), voluntee…

Use of ADCON®-L to Prevent Peridural Fibrosis Following Re-Operation for Recurrent Lumbar Radiculopathy: Clinical Results
2002
OBJECTIVE To present the results of a small retrospective study in patients after they have undergone lumbar scar resection and ADCON-L application to prevent recurrent formation of peridural fibrosis. PATIENTS AND METHODS Between May 1996 and December 1999 nineteen patients underwent surgery for peridural fibrosis. Sixteen patients were eligible for statistical analysis. The mean age was 46.2 years (range 29 to 69 years) and the mean follow-up period was 9.7 months with a range of 3 to 38 months. In 10 patients scar formation was the main factor for nerve root compression. Three out of these patients showed concomitant recurrent disc herniation. Six patients presented with peridural fibros…
Sprint mechanics evaluation using inertial sensor-based technology: A laboratory validation study.
2018
Advances in micro-electromechanical systems have turned magnetic inertial measurement units (MIMUs) into a suitable tool for vertical jumping biomechanical evaluation. Thus, this study aimed to determine whether appropriate reliability and agreement reports could also be obtained when analyzing 20-m sprint mechanics. Four bouts of 20-m sprints were evaluated to determine whether the data provided by a MIMU placed at the lumbar spine could reliably assess sprint mechanics and to examine the validity of the MIMU sensor compared to force plate recordings. Maximal power (P0), force (F0), and velocity (V0), as well as other mechanical determinants of sprint performance associated with the force-…
Bovine pericardium for duraplasty: clinical results in 32 patients.
2001
Bovine pericardium has been widely used for grafts in cardiac surgery and seems to have suitable properties for use as a dural graft. We report on the use of solvent-preserved, gamma-sterilized Tutoplast bovine pericardium for dural grafts in 32 patients undergoing cranial and spinal operations with the objective of clinically assessing this material and technique by a retrospective analysis. All available records were reviewed and information regarding the indication for grafting, complications, and outcome were collected and analyzed for all patients. Indications for grafting included tethered cord myelolysis, closure of lumbosacral myeloceles, Chiari decompression, posterior fossa cranio…
