Paratylenchus shenzhenensis n. sp. was collected from the rhizosphere soil of Anthurium andraeanum in Shenzhen, Guangdong Province, China. The new species is characterized by having a female with a small body (249-302 μm), well developed stylet (17-21 μm), rounded head with four submedian lobes and lip-region with a slight depression at the oral area, small post-vulval uterine sac with a few ve...

The feeding apparatus of Pratylenchus penetrans (Cobb) Chitwood and Oteifa was studied by means of the electron microscope. The stomatostylet is composed of tooth, shaft, and basal knobs. The tooth and shaft are closely interlocked. The tooth forms the outer covering and the inner lining of the anterior half of the stylet, whereas the shaft extends from the basal knobs to the level of the style...

Background. Intubation is the optimal method for opening the airway and effective ventilation of the patient. However, there are occasional problems with intubation, especially in patients with injuries under pre-hospital conditions. Therefore, it is important to identify devices, e.g., videolaryngoscopes or guides, which may facilitate and shorten the procedure. This study addresses the use of...

Intubating conditions under halothane anaesthesia aided with alfentanil 20 micrograms.kg-1 were compared with suxamethonium 2 mg.kg-1 in 40 children presenting for day dental procedures. The condition of vocal cords, jaw relaxation and presence of movement and coughing were scored to give the overall intubating conditions. Successful intubation was achieved in 100% of the suxamethonium group an...

With great interest, we read the recent article by Sheta et al1 comparing performance of the Parker Flex-It stylet and GlideRite Rigid stylet for orotracheal intubation by Glidescope videolaryngoscope in patients with normal airways. They showed that the 2 stylets were equally effective for intubation when used by experienced operators, but the Parker Flex-It stylet was easier and less traumati...

he leading cause of anesthesia-related injury is the nability to intubate the trachea and secure the airway.1 mprovements in video and optical laryngoscopy have llowed to obtain an indirect view of the glottis in a ore simple way but sometimes this advantage occurs ogether with a difficult or impossible endotracheal tube ETT) insertion.2 This is because indirect techniques do not equire the ali...

Intubation stylets are still being used in many medical centers for difficult intubations. Although very rare, it may break inside the trachea during endotracheal intubation despite routine pre-assessments by anesthesiologists and may surprisingly move deep into the tracheobronchial tree. In this case report, we describe a rare complication after stylet or guide-wire intubation in a patient in ...

Meloidogyne platani n. sp. is described and illustrated from specimens obtained from roots of American sycamore, Platanus occidentalis, in Virginia. This new species shows certain similarities with M. arenaria but differs from it by a number of distinctive characters. The perineal pattern of females is rounded with fine, wavy to zig-zag striae and raised, convoluted striae in the inner lateral ...

OBJECTIVE The present study aims to find a convenient, rapid, and stable method to establish bladder tumor in mice. METHODS Female Balb/C-nu-nu nude mice (or female T739 mice) were narcotized by sodium pentobarbital at a dosage of 60 mg/kg. The stylet of the 24# venous retention needles was bent in a 5° to 7° angle at a distance of 15 mm from the needlepoint to form a circle with 2.61 mm to 3...

BACKGROUND Locating pacemaker electrodes can become complicated by congenital abnormalities such as persistent left superior vena cava (LSVC). OBJECTIVE To evaluate a technique for the implanting of ventricular electrode in patients with persistent LSVC. MATERIALS AND METHODS The study was carried out from June 2001 to June 2010 involving all patients who were admitted to the Hospital Unive...
