REVIEW
Xiao-Wei Wang, Ping Li, Shu-Sheng Liu
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...

The stylet penetration behavior of aphids when feeding on plants is associated with virus acquisition and inoculation. Aphidius gifuensis (Ashmead) is a primary endoparasitoid of Myzus persicae (Sulzer) which is the most efficient vector of plant viruses. Information about the effects of parasitoid on aphid and virus transmission can provide an essential foundation for designing effective biological control strategies. This study aimed to investigate the effects of A. gifuensis on the feeding behavior and Potato virus Y (PVY) transmission ability of M...

BACKGROUND: The preferred route for providing nutrition in the pediatric intensive care unit is enteral. Placement of postpyloric feeding tubes using an electromagnetic-tipped stylet that emits a signal detected by a device held over the patient's abdomen is effective in adult intensive care units, but has not been well studied in pediatric units. OBJECTIVES: To determine the effectiveness of the electromagnetic device in reducing the numbers of radiation exposures, intrahospital transports, tubes used, and tube placement attempts in the pediatric intensive care unit...

Lang Yang, Yongqiang Han, Pei Li, Lizhang Wen, Maolin Hou
The brown planthopper (BPH), Nilaparvata lugens (Stål), is a migratory and destructive sucking insect pest of rice. Silicon (Si) amendment to plants can confer enhanced resistance to herbivores and is emerging as a novel approach for pest management. In the present study, we tested the effects of Si addition at 0.16 (low) and 0.32 (high) g Si/kg soil on sucking behaviors and population growth in BPH. Si amendment increased Si content in rice stems and extended non-probing event and phloem puncture followed by sustained phloem ingestion over that in the no-Si-addition control...

Riptortus pedestris (Fabricius) and Halyomorpha halys (Stål) cause injury to soybeans by piercing and sucking pods and seeds. Growers believe that new damage decreases near to harvest despite the occurrence of these bugs at that time. As this question has never been assessed, we evaluated two diets: a) mature soybean pods (dried shell + dried soybean seeds) and b) dried soybean seeds for the two bugs by assessing their biological, behavioral, and morphological attributes on each diet in laboratory. While nymphs of both species were able to develop and adults able to reproduce on the tested diets, bugs fed on pods had longer development times and 2...

The acrostyle is a distinct anatomical region present on the cuticle at the inner face of the common food/salivary canal at the tip of aphid maxillary stylets. This conserved structure is of particular interest as it harbours the protein receptors of at least one plant virus, Cauliflower mosaic virus, and presumably has other roles in plant-insect interactions. Previously we reported immunolabeling of a highly conserved motif of cuticular proteins from the CPR family (named for the presence of a Rebers and Riddiford consensus) within the acrostyle...

In this paper, we describe two new species of Syndesmis living in Pseudechinus magellanicus in the Southwest Atlantic Ocean. The new species have a long stylet in the male reproductive system, which is different from that of the known species of the genus. Specimens of Syndesmis selknami n. sp. have a ∼220-μm-long stylet (∼1/3 of the body length, 0.69 mm). This ratio is unique because only four species (Syndesmis echinorum, Syndesmis rubida, Syndesmis inconspicua and Syndesmis echiniacuti) have similar stylet lengths but are larger in body sizes (3-5 mm)...

Ultrasound guidance for epidural block has improved clinical blind-trial problems but the design of present ultrasonic probes poses operating difficulty of ultrasound-guided catheterization, increasing the failure rate. The purpose of this study was to develop a novel ultrasonic probe to avoid needle contact with vertebral bone during epidural catheterization. The probe has a central circular passage for needle insertion. Two focused annular transducers are deployed around the passage for on-axis guidance. A 17-gauge insulated Tuohy needle containing the self-developed fiber-optic-modified stylet was inserted into the back of the anesthetized pig, in the lumbar region under the guidance of our ultrasonic probe...

The leafhopper Matsumuratettix hiroglyphicus (Matsumura) (Hemiptera: Cicadellidae) is an important vector of phytoplasma causing white leaf disease in sugarcane. Thus, the aim of our study was to understand and describe the stylet-probing activities of this vector while feeding on sugarcane plants, by using direct current (DC) electrical penetration graph (EPG) monitoring. The EPG signals were classified into six distinct waveforms, according to amplitude, frequency, voltage level, and electrical origin of the observed traces during stylet penetration into the host plant tissues (probing)...
