Characterization of Lilium longiflorum cv. ‘Nellie White’ Infection with Root-lesion Nematode Pratylenchus penetrans by Bright-field and Transmission Electron Microscopy

Lilium longiflorum cv. Nellie White, commonly known as Easter lily, is an important floral crop with an annual wholesale value of over $26 million in the United States. The root-lesion nematode, Pratylenchus penetrans, is a major pest of lily due to the significant root damage it causes. In this study, we investigated the cytological aspects of this plant–nematode interaction using bright-field and transmission electron microscopy. We took advantage of an in vitro culture method

The commercial nematicide fosthiazate acting on acetylcholinesterase was used as control.For this reason, scanning electron microscopy and transmission electron microscopy have been employed. The acetic acid mainly harmed the cuticle, degenerated the nuclei of pseudocoel cells, and vacuolised the cytoplasm. The (E)-2-decenal and 2-undecanone did neither harm to the cuticle nor the somatic muscles but they degenerated the

Introduction to Pristionchus pacificus anatomy

extend away from the lateral midline. The nervous system As with C. elegans and other nematodes, the majority of P. pacificus neurons are located in the head and tail. The anterior nervous system of P. pacificus, including the pharynx and anterior amphid sensory neurons, have been reconstructed from serial-section electron microscopy (Bumbarger et al., 2013; Hong et al., 2019). The nervous system of P. pacificus is remarkably similar to that of C. elegans. Both the anterior amphid sensory sensilla

Twenty-four individuals of Narceus gordanus (Diplopoda: Spirobolidae) were collected in Ocala National Forest, FL, between November 2013 and July 2014. Each specimen was dissected to extract the intestine, which was removed and examined for parasitic nematodes.

Palladium Nanotubes for Optical Hydrogen Sensing

Arrays of freestanding upright palladium nanotubes have been fabricated using a bottom-up method of electrodepositing into anodised alumina pores. Optical transmission measurements carried out with a range of postfabrication treatment methods suggest that hydrogen diffuses into both the inner and outer surface areas of the tube structure. Furthermore, scanning electron microscopy of the same sample before and after cycling hydrogen exposure show that the structures appear undamaged by the

Method to Convert a Horizontal Furnace to Grow ZnO Nanowires for Gas Sensing by the VLS Method

. Under a constant flow of Argon gas (200mL/min), the substrates along with a mixture of ZnO and graphite powder are placed in a modified horizontal furnace which uses a 2.54 cm internally mounted quartz tube and are exposed to high temperature (527°C-1000°C) for different growth times. This reaction causes the formation of ZnO nanowires on the substrates. scanning electron microscopy is used to measure the size of the nanowires.

The detailed morphometric measurements obtained were compared with those taken in Australia. Preparation of nematode samples for scanning electron microscopy Scanning electron microscopy (SEM) was used to further characterize P. curvicauda. To do this, single nematodes were fixed in 3% glutaraldehyde in 0.025 M phosphate buffer (pH 7.0) overnight

Morphological and molecular characterization of Paratylenchus beltsvillensis n. sp. (Tylenchida: Paratylenchidae) from the rhizosphere of pine tree (Pinus virginiana Mill) in Maryland, USA

Paratylechus beltsvillensis n. sp. The objective of this study was also to describe this new species using light (LM) and scanning electron microscopy (SEM) and provide its molecular characterization. Materials and methods Nematode samples In September and October of 2020, few soil samples were collected in the Little Paint Branch Park, Beltsville, Prince George’s County, Maryland, USA And sent to the Plant Pest Diagnostic Center, California Department of Food and Agriculture, Sacramento, CA and part of

remodeling of brain parenchyma, including the presence of multiple cell types of immature phenotypes. The latter, as shown by a variety of light and electron microscopy techniques, included endothelial cell precursors as well as nestin-positive immature neural cells of astrocytic or non-glial characteristics. However, there was no evidence of in situ neurogenesis or a considerable migration of cells from SVZ. The centers of the said repair processes were capillary blood vessels connected with basal

Intracellular Siderophore Detection in an Egyptian, Cobalt-Treated F. solani Isolate Using SEM-EDX with Reference to its Tolerance

An Egyptian, plant pathogenic Fusarium solani isolate was grown on cobalt concentrations of 0, 50, 200, 500, 800, and 1000 ppm. The iso­late survived concentrations up to 800 ppm, however failed to grow at 1000 ppm. Morphology and elemental analysis of the isolate under the investigated Co concentrations were studied using Scanning electron microscopy (SEM) and energy dispersive X-ray microanalysis (EDX). The isolate reserved its morphology up to a concentration of 200 ppm. Morphological

Pathogenic Potential of Fresh, Frozen, and Thermally Treated Anisakis spp. Type II (L3) (Nematoda: Anisakidae) after Oral Inoculation into Wistar Rats: A Histopathological Study

dissected to investigate the presence of nematode larvae. Thirty fish (42.9%) of the total were parasitized by nematode larvae which were morphologically identified as Anisakis spp. Type II (L3) according to light and scanning electron microscopy. The pathogenic potential of oral inoculation of fresh, frozen, and thermally treated larvae into Wistar rats was elucidated by histological examination of their thymus and spleen. Results obtained indicated that neither cooling nor freezing of the parasite

Effects of epidural compression on stellate neurons and thalamocortical afferent fibers in the rat primary somatosensory cortex

-lesion. Anterograde tracing analyses exhibited a progressive decline of TCA fiber density in barrel field for 6 months post-lesion. Due to the abrupt decrease of TCA fiber density at 3 days after compression, we further used electron microscopy to investigate the ultrastructure of TCA fibers at this time. Some TCA fiber terminal profiles with dissolved or darkened mitochondria and fewer synaptic vesicles were distorted and broken. Furthermore, the disruption of mitochondria and myelin sheath was
