BACKGROUND: During McGrath videolaryngoscope (VL) intubation, a styletted endotracheal tube maintaining an upward distal tip angle is recommended by some manufacturers. However, a styletted endotracheal tube can elicit rare but potentially serious complications. The purpose of this study was to demonstrate that a nonstyletted tube with exaggerated curvature would be noninferior to a styletted tube for orotracheal intubation using McGrath VL in patients with expected normal airway, by comparing the time to intubation and ease of intubation...

Yanan Hao, Christopher H Dietrich, Wu Dai
Development of the mouthparts in the cicada Meimuna mongolica (Distant) is investigated here for the first time using scanning electron microscopy in order to document changes occurring in different nymphal instars and from nymph to adult, during which a shift from subterranean root-feeding to feeding on aboveground parts of the host plant occurs. The structure and component of mouthparts is similar to those found in other hemipteran insects. Fourteen types of sensilla and five types of cuticular processes were found on the mouthparts of nymphs and adults...

Difficult airway management remains one of the key points in our specialty, as the difficulty or impossibility of tracheal intubation is the main cause of morbidity/mortality attributable to anaesthesia. Rett syndrome is a severe and incapacitating neurological disease. We present the case of a 21-year-old girl affected by this syndrome, with significant psychomotor retardation and difficult airway predictors, who was scheduled to have a laparoscopic cholecystectomy under general anaesthesia. We decided on one attempt of Clarus Video System(®) fiberoptic intubation as primary intervention...

Wasa Ueda, Young-Chang P Arai
This study involved 154 anesthetized patients requiring endotracheal intubation, in whom the epiglottis was visible but not lifted, which restricted the view of the glottis. A simple stylet was used to lift the epiglottis, thus improving the view of the glottis with the Glide Scope®, allowing tracheal tubes to be inserted into the patients. The stylet easily resolved the difficulty of lifting the epiglottis when using a video laryngoscope, thus facilitating endotracheal intubation in patients undergoing general anesthesia...

OBJECTIVE: The videolaryngoscope has gained popularity for providing superior visualization in intubations. A rare complication of this technology is soft palate injury. Through a literature review and case series, we highlight the risks associated with the Glidescope and McGrath videolaryngoscopes and the management of soft palate injuries. METHOD: A case series of multi-institutional review of medical records was performed to identify patients with soft palate injuries from the videolaryngoscope...

Herbivore selection of plant hosts and plant responses to insect colonization have been subjects of intense investigations. A growing body of evidence suggests that, for successful colonization to occur, (effector/virulence) proteins in insect saliva must modulate plant defense responses to the benefit of the insect. A range of insect saliva proteins that modulate plant defense responses have been identified, but there is no direct evidence that these proteins are delivered into specific plant tissues and enter plant cells...

BACKGROUND: Infant lumbar punctures (LPs) are common procedures performed in the emergency department. However, 10% to 35% of these LPs are unsuccessful or grossly bloody, which can lead to increased hospitalization, increased costs, and prolonged exposure to antibiotics or antivirals. Point of care ultrasound (POCUS) may help to surmount the intrinsic causes of LP failure by providing a visual guide of the vascular structures in the needle path before a LP is performed. CASE REPORT: We report two cases where color flow Doppler POCUS was used to identify vascular structures around the spinal canal in infants before attempting a LP...

Cereal cyst nematodes are sedentary biotrophic endoparasites that maintain a complex interaction with their host plants. Nematode effector proteins are synthesized in the oesophageal glands and are secreted into plant tissues through the stylet. To understand the function of nematode effectors in parasitic plants, we cloned predicted effectors genes from Heterodera avenae and transiently expressed them in Nicotiana benthamiana. Infiltration assays showed that HaEXPB2, a predicted expansin-like protein, caused cell death in N...

PURPOSE: The development of MR-guided high dose rate (HDR) brachytherapy is under investigation due to the excellent tumor and organs at risk visualization of MRI. However, MR-based localization of needles (including catheters or tubes) has inherently a low update rate and the required image interpretation can be hampered by signal voids arising from blood vessels or calcifications limiting the precision of the needle guidance and reconstruction. In this paper, a new needle tracking prototype is investigated using fiber Bragg gratings (FBG)-based sensing: this prototype involves a MR-compatible stylet composed of three optic fibers with nine sets of embedded FBG sensors each...

BACKGROUND: Pacing in the Bachmann's bundle (BB) area (upper atrial septum) appears superior to right atrial appendage or free wall stimulation for the prevention of paroxysmal atrial fibrillation in patients with atrial conduction delay. However, insertion of active fixation lead in the upper atrial septal position is difficult and time consuming with conventional stylet, inhibiting application of this pacing method in routine practice. METHODS: The technique of positioning the atrial lead in BB with hand-made stylet is presented with emphasis on electrocardiographic P-wave pattern and fluoroscopic landmarks...

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...

Jane Halliday, Ian Kamaly
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...
