BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) of thoracic structures is a commonly performed tissue sampling technique. The usage of an inner-stylet in the EBUS needle has never been rigorously evaluated, and may be unnecessary. METHODS: In a prospective randomized single blinded controlled clinical trial, patients with a clinical indication for EBUS-TBNA underwent lymph node sampling using both with-stylet and without-stylet techniques...

Spiral nematode species of the genus Rotylenchus have been reported on olive (Olea europaea L.) in several Mediterranean countries (Castillo et al., 2010; Ali et al., 2014). Nematological surveys for plant-parasitic nematodes on olive trees were carried out in Tunisia between 2013 and 2014, and two nematode species of Rotylenchus were collected from the rhizosphere of olive cv. Chemlali in several localities of Tunisia (Tables 1,2 [Table: see text] [Table: see text] ). Twenty-two soil samples of 3 to 4 kg were collected with a shovel from the upper 50 cm of soil from arbitrarily chosen olive trees...

Plant-parasitic nematode species have been reported on several occasions from coastal sand dunes, including Longidorus and Rotylenchus species (Vovlas et al., 2008; De Luca et al., 2009; Mateille et al., 2014). In April 2016, 10 soil samples of 3 to 4 kg from the rhizosphere of Tamarix smyrnensis with different vegetation around (viz. Elymus farctus, Lycium schweinfurthii, Crithmum maritimum, and Arthrocnemum sp.) were collected for diagnosis of plant-parasitic nematodes. The area of sampling was a coastal sand dune near the archeological site of Komos, southwest of Crete, Greece...

BACKGROUND: Neuronavigation, the ability to perform real-time intra-operative guidance during cranial and/or spinal surgery, has increased both accuracy and safety in neurosurgery [2]. Cranial navigation of existing surgical instruments using Brainlab requires the use of an instrument adapter and clamp, which in our experience renders an endoscope 'top-heavy', difficult to manipulate, and the process of registration of the adapter quite time-consuming. METHODS: A Brainlab Disposable Stylet was used to navigate fenestration of an entrapped temporal horn in a pediatric case...

We review half a century of research on Cucumis melo resistance to Aphis gossypii from molecular to field levels. The Vat gene is unique in conferring resistance to both A. gossypii and the viruses it transmits. This double phenotype is aphid clone-dependent and has been observed in 25 melon accessions, mostly from Asia. It is controlled by a cluster of genes including CC-NLR, which has been characterized in detail. Copy-number polymorphisms (for the whole gene and for a domain that stands out in the LLR region) and single-nucleotide polymorphisms have been identified in the Vat cluster...

PURPOSE: To study the ability of a human operator to manually correct for errors in the needle insertion path without partial withdrawal of the needle by means of an active, tip-articulated steerable needle. MATERIALS AND METHODS: The needle is composed of a 1.32-mm outer-diameter cannula, with a flexure joint near the tip, and a retractable stylet. The bending stiffness of the needle resembles that of a 20-gauge hypodermic needle. The needle functionality was evaluated in manual insertions by steering to predefined targets and a lateral displacement of 20 mm from the straight insertion line...

Two new species of brackish-water Macrostomum (M. zhujiangensis n. sp. and M. baoanensis n. sp.) were described based on samples collected from the littoral zone of the Zhujiang Estuary. These are the first records of brackish-water Macrostomum from southern China. Macrostomum zhujiangensis n. sp. and M. baoanensis n. sp. differ from other similar species in the length and morphology of the penis stylet.  The penis stylet of M. zhujiangensis n. sp. is C-shaped and its distal opening has a beveled edge. The penis stylet of M...

INTRODUCTION: Scleroderma is a progressive fibrotic disorder of connective tissue which can present multiple anesthetic challenges to anesthetists, especially airway management. Awake intubation with fiberoptic bronchoscope is widely accepted and implemented for progressive systematic scleroderma patients. With the development and improvement of intubation devices these years, there is no report addressing other intubation methods for sclerotic patients. CASE DESCRIPTION: A 47 year-old, 42-kg man with 1-year history of localized scleroderma was scheduled for the operation of inner fixation after 6 days of his acetabular fracture...

: Sacral nerve stimulation (SNS) is effective for faecal incontinence (FI). Little is known about the relationship between the implantation technique and the functional outcome. AIM: The study aimed to explore the relationship between the numbers of active electrode poles (AEP) used during permanent lead placement and subsequent function, therapeutic amplitude and the need for extra appointments between scheduled follow-up visits. METHOD: 186 patients with FI who underwent permanent implantation between May-2009 and March-2015 with a tined (barbed) lead (3093/3080-Medtronic) using the straight stylet were registered on the European two-centre SNS prospective database (SNSPD)...

Compared with a lightwand which is used blind, Optiscope(™) , a rigid video-stylet, can provide direct imaging of airway structures, potentially offering improved conditions in cervical spine-immobilised patients. We randomly assigned 168 patients who required cervical immobilisation during tracheal intubation to use of the Optiscope or the lightwand. The initial intubation success rate (95% CI) was 90 (82-95)% with the Optiscope and 87 (78-93)% with the lightwand (p = 0.626). Median (IQR [range]) intubation time was longer (19 (12-41 [5-195] s vs...
