Microsc Res Tech 2019 Feb 15. Epub 2019 Feb 15.

Department of Information Systems, Al Yamamah University, Riyadh, KSA.

Skin cancer is being a most deadly type of cancers which have grown extensively worldwide from the last decade. For an accurate detection and classification of melanoma, several measures should be considered which include, contrast stretching, irregularity measurement, selection of most optimal features, and so forth. A poor contrast of lesion affects the segmentation accuracy and also increases classification error. Read More

Sample preparation method for visualization of nanoparticulate captured on mixed cellulose ester filter media by enhanced darkfield microscopy and hyperspectral imaging.

Microsc Res Tech 2019 Feb 15. Epub 2019 Feb 15.

College of Nanoscale Science, Nanobioscience Constellation, State University of New York (SUNY) Polytechnic Institute, College of Nanoscale Science, New York.

A significant hurdle in conducting effective health and safety hazard analysis and risk assessment for the nanotechnology workforce is the lack of a rapid method for the direct visualization and analysis of filter media used to sample nanomaterials from work environments that represent potential worker exposure. Current best-known methods include transmission electron microscopy (TEM) coupled with energy dispersive x-ray spectroscopy (EDS) for elemental identification. TEM-EDS is considerably time-, cost-, and resource-intensive, which may prevent timely health and safety recommendations and corrective actions. Read More

Detoxification and functionalization of gold nanorods with organic polymers and their applications in cancer photothermal therapy.

Microsc Res Tech 2019 Feb 14. Epub 2019 Feb 14.

Institute of Applied Bioresource, College of Animal Sciences, Zhejiang University, Zhejiang, Hangzhou, People's Republic of China.

Gold nanorods (AuNRs) have attracted widespread attention in the last few decades due to their potential applications in cancer photothermal therapy (CPTT). However, the utilization of AuNRs is restricted because of their high toxicity for cells and tissues. Numerous methods have been developed to solve this problem, among which the most convenient one is to coat AuNRs with biocompatible materials or replace their original toxic surfactant such as the hexadecyl-trimethyl ammonium bromide (CTAB).

Exodontia-induced muscular hypofunction by itself or associated to chronic stress impairs masseter muscle morphology and its mitochondrial function.

Microsc Res Tech 2019 Feb 11. Epub 2019 Feb 11.

Department of Morphology, Physiology and Basic Pathology of Dentistry School of RibeirãoPreto, University of São Paulo, Ribeirão Preto, São Paulo, Brazil.

Stress is associated with orofacial pain sensitivity and is qualified as a temporomandibular disorder risk factor. During stressful periods, painful thresholds of masticatory muscles in individuals suffering muscle facial pain are significantly lower than in controls, but the exact physiologic mechanism underlying this relation remains unclear. Our hypothesis is that chronic unpredictable stress and masticatory hypofunction induce morphologic and metabolic masseter muscle changes in rats. Read More

Estimating volumes from common carp hepatocytes using design-based stereology and examining correlations with profile areas: Revisiting a nutritional assay and unveiling guidelines to microscopists.

Microsc Res Tech 2019 Feb 7. Epub 2019 Feb 7.

Laboratory of Histology and Embryology, Department of Microscopy, Institute of Biomedical Sciences Abel Salazar (ICBAS), University of Porto (U.Porto), Porto, Portugal.

Assessing fish liver status is common in aquaculture nutrition assays. This often implies determining hepatocytes profile areas in routine thin (5-7 μm) histological sections. However, there are theoretical problems using planar morphometry in thin sections: inherent sampling cells biases, too small numbers of sampled cells, under/overestimation of size, measuring size as areas when cells are three-dimensional (3D) entities.

Microsc Res Tech 2019 Jan 5. Epub 2019 Jan 5.

Department of Bioengineering, Faculty of Biology, Lomonosov Moscow State University, Moscow, Russia.

Drying is a critical step in preparing cell samples for examination with scanning electron microscopy (SEM). The two commonly used drying procedures are the critical point drying (CPD) and the chemical drying using hexamethyldisilazane (HMDS drying). Here we compared the application of these procedures for the drying of HaCaT human keratinocyte cells grown on electrospun nylon mats. Read More

Microsc Res Tech 2019 Jan 5. Epub 2019 Jan 5.

Faculty of Dentistry, Department of Pediatric Dentistry, Izmır Katip Celebi University, Izmir, Turkey.

The purpose of this study was to evaluate the micro-tensile bond strength (μTBS) of dentin bonding agents containing different ratios of nano-sized hydroxyapatite fillers (HA). X-ray diffraction analysis was used for characterization, and scanning electron microscope (SEM) analysis was used to determine the HA particle size after that HA were mixed a bonding agents without filler. Dentin bonding agents were divided into four groups according to addition of different ratios of nano-sized hydroxyapatite fillers as 2% HA, 5% HA, 7% HA, and no-filler control group. Read More

Department of Microbiology, Faculty of Dentistry, University of Granada, Granada, Spain.

The purpose of this study was to test the antimicrobial activity and the smear layer removal of different irrigation protocols-sodium hypochlorite (NaOCl), NaOCl followed by ethylenediaminetetraacetic acid (EDTA), and NaOCl combined with etidronic acid (HEBP)-against infected dentine tubules during root canal preparation. Single rooted premolars contaminated with Enterococcus faecalis were chemomechanically prepared. Depending on the irrigation protocols, the roots were divided into the following groups: (1) distilled water during and after instrumentation; (2) 2. Read More

Seed micromorphology and its taxonomic evidence in subfamily Alsinoideae (Caryophyllaceae).

Microsc Res Tech 2018 Dec 30. Epub 2018 Dec 30.

Department of Plant sciences, Quaid-i-Azam University, Islamabad, Pakistan.

Seed micromorphology of 13 species, belonging to four genera of subfamily Alsinoideae (Caryophyllaceae) were investigated with scanning electron microscopy (SEM), in order to assess their diagnostic significance at generic level and provide additional evidence on species delimitation, as well as correct identification and phylogenetic position. Genera and species of subfamily Alsinoideae exhibit great variation in ultrastructure and a high diversity of novel micromorphological characters were observed. Variation in seed shape, color, hilum, anticlinal wall, epidermal cell, cell surface, margins, and quantitative characters as length and width were studied in detail, compared, illustrated, and their taxonomic significant were discussed.

Spruce wood (picea abis) has been widely used as structural element, from buildings to musical instruments, due to its outstanding mechanical performances. The main stem transverse section exhibits growth rings formed by periodic fringes patterns, which are constituted by lamellae-tracheid arrangements. In order to improve the understanding of each wood microstructure role, the morphology and crystallinity of earlywood and latewood fibers were examined mainly using scanning electron microscopy, atomic force microscopy, and X-ray difracction.

Histomicroscopy and normal anatomy of the adult killifish Aphanius hormuzensis (Teleostei; Aphaniidae) from the Persian Gulf coastal environment.

Microsc Res Tech 2018 Dec 27. Epub 2018 Dec 27.

Department of Biology, Faculty of Sciences, Shahid Bahonar University of Kerman, Kerman, Iran.

The histomicroscopy and normal anatomy of the major body organ systems were investigated in the adult killifish, Aphanius hormuzensis using histological examination, X-ray imaging, double staining, light microscopy and scanning electron microscopy (SEM). Based on the histomicroscopic observations, the kidney, liver and swim bladder in the studied species were comparable to other fish models. The anterior portion of the kidney is bulbous, while the posterior portion is narrow and elongated; the liver has a single lobe and the swim bladder is a single-chambered organ with no connection to the digestive tract (physoclistous).
