Optical Microscopy Examination of 5MeODMT Benzoate

Check if the same lab product or an alternative is used in the 5 most similar protocols

Example 20

Optical microscopy examination was undertaken using an Olympus BX53M polarised light microscope and an Olympus SC50 digital video camera for image capture using imaging software Olympus Stream Basic, V2.4. The image scale bar was verified against an external graticule, 1.5/0.6/0.01 mm DIV, on a monthly basis.

A small amount of each sample was placed onto a glass slide and dispersed using mineral dispersion oil if required. The samples were viewed with appropriate magnification and various images recorded.

Optical micrographs of 5MeODMT benzoate salt, were acquired. The material is composed of large rhombohedral/trigonal crystals, ranging from 400 to 1000 microns. There are also small crystals adhering to the large crystals. Some of the small crystals, from 10 microns, are a consequence of mechanical attrition, but others have formed by crystallisation. There are also large aggregates composed of various habits. FIGS. 13 to 16 show various optical micrographs of 5MeODMT benzoate at various magnifications.

Fiber Morphology and Density Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Morphology and geometry of fibers were evaluated by the counting method using software Olympus Stream Basic [25 (link)]. The average diameter of fibers was determined manually for each fiber on the z-stack at five different points of the sample excluding defective areas.
Average density characterizes the mass per unit volume of the material. The data were averaged over ten samples. The density, δ , was defined as: δ=ml×B×b
where m is the mass; l is the length; B is the width; and b is the thickness.
Theoretical porosity is the percentage of the mass of the material and the fiber-free volume. The data were averaged over five samples.

The structure of fibrous materials was evaluated by the counting method using the software Olympus Stream Basic (Tokyo, Japan). PHB-Fe(TPP)Cl and PHB-Hmi samples 100 × 100 mm were used for the counting method.
The average diameter of fibers was determined manually for each fiber on the z-stack at 10 different points of the sample excluding defective areas.
Average density characterizes the mass per unit volume of the material. The data were averaged over 10 samples. The density, δ, was defined as: δ=mlxBxb,
where m is the mass; l is the length; B is the width; and b is the thickness.
Theoretical porosity is the percentage of the mass of the material and the fiber-free volume. The data were averaged over five samples.

Histological Assessment of Skin Angiogenesis

Check if the same lab product or an alternative is used in the 5 most similar protocols
At the end of the experimental period, the animals were sacrificed and skin samples were harvested for histological examination. Skin samples were fixed in 10% buffered neutral formalin, embedded in paraffin, sections were made at 4 micrometers and the slides were stained by Haematoxiline–Eosine (HE) method. The slides were examined under a microscope Olympus BX 51. The images were taken with Olympus UC 30 digital camera and processed by a special image acquisition and processing program: Olympus Stream Basic. The angiogenesis was assessed by α-SMA immunostaining using a mouse monoclonal antiα-SMA antibody (clone 1A4) (Abcam ab76549) in a 1:800 dilution. The reaction was carried by a Leica Bond-Max (Leica Microsystems, Wetzlar, Germany) automated immunostainer using a polymer-based detection system (Leica Biosystems, Wetzlar, Germany) with 3,3′-Diaminobenzidinew (DAB) as the chromogen. Masson-Goldner’s trichrome (TM)-stained method was used for histological examination during the wound healing process (day 8).

Aeolian Sand Dune Arthropod Diversity Assessment

Check if the same lab product or an alternative is used in the 5 most similar protocols
We carried out our research on aeolian sand dunes located in Záhorie Protected Landscape Area, Borská nížina, during 2018 and 2019 (Fig. 1,2A). The study area serves as a military complex used by the Slovak army. Additionally, three males of W. stylifrons were collected in a viticultural landscape near the town of Modra (Fig. 2B). The material was obtained using pitfall traps.
Measurements of W. stylifrons were obtained using an Olympus SC 100 attached to an Olympus SZx16 stereomicroscope and edited with Olympus Stream basic. Measurements of S. mongolica were taken from digital images using the AxioVision 40LE application. Digital photographs were taken using a Canon EOS 5D Mark II camera attached to a Zeiss Axio Zoom V16 stereomicroscope. Image stacks were produced manually, combined using Zerene Stacker software and subsequently edited in Adobe Photoshop CC. Nomenclature follows World Spider Catalog (2021).
The specimens are preserved in 70% ethanol and deposited in the collections of Institute Landscape Ecology SAS in Nitra (ILE SAS, curator: P. Purgat).

For the histological study, the hepatic samples were fixed in 10% buffered neutral formalin, embedded in paraffin, while sections were made at 4 micrometers and the slides were stained with hematoxylin and eosin (H&E) dye. Then the slides were examined under an Olympus BX 51 microscope. The images were taken with an Olympus UC 30 digital camera and processed by a special image acquisition and processing program, i.e. Olympus Stream Basic.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
