Abstract:

Background: Percutaneous needle electrolysis (PNE) consists of a galvanic current combined with the insertion of a solid needle into the tissues of the musculoskeletal system. The application of a galvanic current through a needle can alter the morphology and composition during treatment application. This procedure may also provoke a localized temperature increase. Aim: The aim was to evaluate the safety of the PNE procedure by analyzing possible alterations of the needles employed. Methods: Physio Invasiva® and AguPunt EPI® brand needles, commonly used for the application of this technique, w

Abstract:

In the present study, needle variation of Scots pine (Pinus sylvestris L., Pinaceae) populations in Turkey was investigated. From selected eight populations, a total of 1314 needles belonging to 206 trees were examined. Four morphological needle traits were measured and analyzed to describe the population diversity and differentiation. Analyzed morphological traits showed significant variability. The trees within populations differ significantly in all analyzed needle characteristics, while the differences between populations were significant for the three of four studied characteristics.

Background: Nanofiber’s productivity plagues nanofibrous membranes’ applications in many areas. Herein, we present the needle-disk electrospinning to improve throughput. In this method, multiple high-curvature mentals are used as the spinning electrode. Methods: Three aspects were investigated: 1) mechanism elucidation of the needle-disk electrospinning; 2) parameter optimization of the needle-disk electrospinning; 3) productivity improvement of the needle-disk electrospinning. Results: Results show that high-curvature electrode evokes high electric field intensity, making lower voltage supply

Abstract:

Abstract Background The use of galvanic currents (GC), during percutaneous needle electrolysis (PNE) can make needles release metals and therefore decrease their diameter and increase resistance. If this were very marked, this could increase the temperature of the needle during use of the same. Furthermore, the loss of materials such as zinc, can trigger allergic reactions in people who are sensitive to these metals. Aim to evaluate modifications of needles during the application of GC in PNE. Methods The resistance was evaluated using a Digital multimeter Velleman DVM92. The GC was generated

Mean SLA was found to be 50 ± 17 cm2/g. High correlation of SLA and 100-needle dry mass with DBH, crown position, and needle age was found.

Abstract:

Context.—Cytology relies heavily on morphology to make diagnoses, and morphologic criteria have not changed much in recent years. The field is being shaped predominantly by new techniques for imaging and for acquiring and processing samples, advances in molecular diagnosis and therapeutics, and regulatory issues. Objective.—To review the importance of classical morphology in the future of cytopathology, to identify areas in which cytology is expanding or contracting in its scope, and to identify factors that are shaping the field. Data Sources.—Literature review. Conclusions.—Five stories pain

Abstract:

Pine needle blight of Pinus massoniana caused by pathogens of the Pestalotiopsis genus is a destructive disease worldwide, especially in young forests. Chemical fungicides accelerate the formation of resistant strains among plant pathogenic fungi, which makes microbial biocontrol particularly important. In this study, we identified Neopestalotiopsis camelliae-oleiferae as a new pathogen of pine needle blight in P. massoniana via pathogen isolation, inoculation, pathogenicity assays, morphology observations, and multilocus phylogenetic analyses of the ITS, TEF1, and TUB2 regions.

Abstract:

In this study, a nanostructured needle-like hydroxyapatite (HA) coating was prepared by the sodium citrate template-assisted hydrothermal method on magnesium alloy (AZ31). The influence of sodium citrate on the composition, microstructure and corrosion behavior of the coatings was studied. The results showed that with the increase in the mole ratio of Ca/sodium citrate from 1 to 13, the coating gradually changed from the needle-like morphology of HA to the flake morphology of β-tricalcium phosphate (β-TCP), which was related to the existing form of citrate in the solution and the trend of comp

Abstract:

AbstractVarious morphologies of magnesium carbonate hydrate had been synthesized without using any organic additives by carefully adjusting the reaction temperature and time during the talc carbonation process. At lower temperatures, magnesium carbonate hydrate was prone to display needle-like morphology. With the further increase of the carbonation temperature, the sheet-like crystallites became the preferred morphology, and at higher aging temperatures, these crystallites tended to assemble into layer-like structures with diverse morphologies, such as rose-like particles and nest-like struct

Abstract:

This paper presents a combined optical imaging/artificial intelligence (OI/AI) technique for the real-time analysis of tissue morphology at the tip of the biopsy needle, prior to collecting a biopsy specimen. This is an important clinical problem as up to 40% of collected biopsy cores provide low diagnostic value due to high adipose or necrotic content. Micron-scale-resolution optical coherence tomography (OCT) images can be collected with a minimally invasive needle probe and automatically analyzed using a computer neural network (CNN)-based AI software. The results can be conveyed to the cli

Abstract:

Abstract Needle-punched (NP) carbon/carbon composites (CCCs) are widely used in structures re-entering the atmosphere of aerospace, thanks to their excellent mechanical properties. They are easily oxidized at high temperatures with atmospheric oxygen. The oxidation behavior is influenced by the process of heat conduction. In this study, longitudinal and transverse heat conduction in micro- and mesoscale models of CCCs was investigated. It was established that the heat transfer interface of a fiber bundle demonstrated peak-like morphology, while the punching structures of composites slowed down

In this study, heat-acupuncture needle was coated with bioceramics by applying a plasma spray coating method to prevent a skin burn in the heat-acupuncture therapy. The effect of coating on the surface roughness of heat-acupuncture needle was investigated and the surface morphology was examined by scanning electron microscope (SEM). The effect of coating on the heat conduction of heat-acupuncture needle was also investigated. The results showed that the surface roughness of uncoated, Al2O3, and ZrO2 coated needle was 0.0675um, 8.568um, and 3.285um, respectively. The surface of ZrO2 coated need

Abstract:

Electrospinning can be used to produce nanofiber mats containing diverse nanoparticles for various purposes. Magnetic nanoparticles, such as magnetite (Fe3O4), can be introduced to produce magnetic nanofiber mats, e.g., for hyperthermia applications, but also for basic research of diluted magnetic systems. As the number of nanoparticles increases, however, the morphology and the mechanical properties of the nanofiber mats decrease, so that freestanding composite nanofiber mats with a high content of nanoparticles are hard to produce. Here we report on poly (acrylonitrile) (PAN) composite nanof
