BACKGROUND: Endoscopic ultrasound with fine-needle aspiration (EUS-FNA) is the most efficacious way to collect specimens from a solid lesion adjacent to the gastrointestinal tract and is performed with an internal stylet during puncture. However, its reinsertion into the needle is time-consuming. Controversy surrounds whether quality of cytology specimen improves with stylet use. We performed a meta-analysis comparing the use of stylet versus no stylet with EUS-FNA of gastrointestinal-related masses...

BACKGROUND: Neonatal endotracheal intubation is a common and potentially life-saving intervention. It is a mandatory skill for neonatal trainees, but one that is difficult to master and maintain. Intubation opportunities for trainees are decreasing and success rates are subsequently falling. Use of a stylet may aid intubation and improve success. However, the potential for associated harm must be considered. OBJECTIVES: To compare the benefits and harms of neonatal orotracheal intubation with a stylet versus neonatal orotracheal intubation without a stylet...

Bemisiatabaci is an important vector of numerous plant viruses, including the emergent semi-persistently transmitted crinivirus Tomato chlorosis virus (ToCV). Its vector feeding behaviour is complex, with important implications for virus transmission, epidemiology and control. Thus, the objective of this study was to investigate the role of the stylet penetration activities of B. tabaci in the inoculation of ToCV in tomatoes by using the electrical penetration graph (EPG) technique. EPG recordings were classified into six categories depending on the waveforms observed...

Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) and brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), are global economic pests that may co-occur on small fruits. We investigated whether fruit recently exposed to H. halys affected subsequent host use by D. suzukii. Laboratory no-choice and choice tests presented D. suzukii with H. halys-fed and unfed raspberries and blueberries immediately or 3 d after H. halys feeding. Resulting D. suzukii eggs, or larvae and pupae, were counted...

REVIEW

Whiteflies are important pests of many crops worldwide. They are polyphagous and effectively feed on phloem sap using mouthparts modified into long, flexible stylets. Plants respond to whitefly attack by activating defense genes leading to production of toxic compounds. To reach plant phloem and survive on host plants, whiteflies secret effectors in the saliva to regulate plant responses and activate detoxification system to cope with plant defenses. Additionally, whitefly-transmitted viruses may exert substantial effects on host plants and in turn the performance of whiteflies...

BACKGROUND: Most high-riding distal basilar trunk aneurysms can be surgically approached via the transsylvian route and its orbitozygomatic variant. However, on rare occasions, the basilar bifurcation may be unusually high and an approach above the carotid terminus may be required. OBJECTIVE: In this cadaveric study, we sought to determine the feasibility and exposure limits of the interlenticulostriate approach (ILSA). METHODS: A standard transsylvian approach was performed in 10 cerebral hemispheres of 5 formalin-fixed, silicone-injected cadaver heads...

BACKGROUND AND AIMS: Video Stylet (VS) is a new intubating modality that provides real-time video of endotracheal intubation (ETI). This device does not need alignment of the oral, pharyngeal and tracheal axes to view glottis and can be used in patients with limited mouth opening. The aim of this study was to compare flexible fibre-optic (FO) bronchoscope with VS in elective surgical patients in apparently normal airway patients requiring oral ETI. METHODS: Sixty patients undergoing elective surgery under general anaesthesia of age group 20-60 years, weight 40-70 kg, American Society of Anesthesiologist 1 and 2 and modified Mallampatti I and II were included in the study...

Spiral nematodes (Helicotylenchus spp.) are common plant-parasitic nematodes in fields of many crops. In June 2015, two soil samples were collected from a soybean field in Richland County, ND. Nematodes were extracted from soil using the sugar centrifugal flotation method (Jenkins, 1964). Plant-parasitic nematodes were identified to genus based on morphological features and counted. Both samples contained spiral nematodes from 1,500 to 3,300 per kilogram of soil. In June and August 2016, 10 soil samples were collected from the same field...

The treatment of biliary stenosis after pediatric LDLT is challenging. We describe an innovative technique of peripheral IHCJ for the treatment of patients with complex biliary stenosis after pediatric LDLT in whom percutaneous treatment failed. During surgery, the percutaneous biliary drainage is removed and a flexible metal stylet is introduced trough the tract. Subsequently, the most superficial aspect of the biliary tree is recognized by palpation of the stylet's round tip in the liver surface. The liver parenchyma is then transected until the bile duct is reached...
