Elean Morian D1 Check

€

Description Polyphenols are a type of antioxidant found in extra virgin olive oil. Like other antioxidants, polyphenols help combat oxidative stress and can contribute to the prevention of diseases such as heart disease, high blood pressure, and certain cancers. Additionally, polyphenols possess anti-aging and powerful anti-inflammatory properties. A recent study revealed that extra virgin olive oil contains a specific phenol compound called oleocanthal, which acts similarly to the substance ibuprofen in the body. This suggests the potential for olive oil to help reduce the risk of stroke. It is believed that consuming two tablespoons of extra virgin olive oil a day is sufficient to provide these anti-inflammatory benefits. Several factors influence the polyphenol content in olive oil. Earlyharvested (unripe) olives typically contain more polyphenols than late harvested (ripe) olives. Furthermore, the aging process and the preservation of olive oil affect its polyphenol content; poorly preserved or aged oils tend to have fewer polyphenols due to oxidation. Finally, the quality of the olive oil itself matters—the more processed it is, the lower its phenol content will be. Suggested use: The Elean Morian D1 kit, developed by MenidiMedica Biotech Greece, is a rapid and straightforward semi-quantitative tool designed for the measurement of oleacrine and oleocanthal in olive oil. The kit includes all the essential materials to conduct 10 tests. Method principle: In an olive oil sample, Oleasin and oleocanthal undergo a biochemical reaction with the provided reagents, resulting in the production of distinct color shades. The observed color shades, along with their corresponding color range, serve as indicators of the concentration of oleazine and oleocanthal in the olive oil, expressed in mg/L. Materials enclosed in the kit: - 10x Substrate A reagent - 10x Starting Reagent B - 10x Finishing Reagent C - 1x Sample Dispenser - 1x Colour Scale Tab Storage: The kit should be stored at room temperature (18-30°C). It is important to avoid high temperatures and exposure to sunlight. Refrigeration of the kit is not recommended. Method Procedure: 1. Open vials A and B. 2. Pour the contents of vial B into vial A. 3. Close the cap on vial A. 4. Gently shake vial A for 5 seconds to achieve homogenization. 5. Collect a sample of olive oil with the dosing device. 6. Open vial A. 7. Pour a drop of olive oil into vial A. 8. Close vial A and shake gently for 5 seconds to achieve homogenization. 9. Wait for 3 minutes. 10. Open vials A and C. 11. Pour the contents of vial C into vial A. 12. Close the cap of vial A. 13. Gently shake vial A for 5 minutes to achieve homogenization. 14. Wait for an additional 5 minutes. 15.

SPERM FERTILITY CHECK

€

THE ART OF MALE FERTILITY Self Test for Male Fertility Potential General information Around 10-15% of reproductive-age couples experience infertility, and 40-50% of these cases are linked to sperm-related issues. The Sperm Fertility Check is a tool designed to assess whether a sperm sample exhibits normal or subnormal activity. Sperm with normalactivity levels are more likely to improve the likelihood of achieving pregnancy. Warnings and precautions Keep the kit out of reach of children. The blue dye included is toxic and should not be ingested as it poses a risk if swallowed. It can also irritate the skin, eyes, and respiratory tract. Ensure you thoroughly read all the information provided in this pamphlet before conducting the test. Familiarize yourself with the procedure first. To reduce the risk of contaminating the dye, avoid any contact with the tip of the dye bottle. Storage and use The Sperm Fertility Check kit is effective for up to 24 months from the manufacturing date and should be kept within a temperature range of 2-30°C in its original, sealed packaging. Opening the color dye bottle does not affect its shelf life, provided there is no contact with the bottle's tip or the dye itself. Conduct the test at a room temperature between 20-30°C. Performing the test in an environment that is too cold may cause the water's temperature in the cup to drop rapidly, potentially leading to inaccurate, false negative results. The test tubes and funnels are designed for single use only; dispose of them after one use and use a new set for any subsequent tests. Material included with the kit - color chart - funnel x 2 - test tube x 2 - water cup with snap cap - thermometer x 2 - squeeze bottle with dye - Sterile urobox x 2 Material not included with the kit - Hot water (48°C to 50°C), a drinking glass and incandescent light. Instructions for use 1. The reagent bottle's dye should be a dark blue color, matching the "Control" hue on the color chart. If the dye appears clear or pink, it indicates a defect, and you should return the kit. If the dye's color is as expected, proceed to step 2. 2. Open an urobox by removing its packaging. Take off the cap and collect the sample by masturbating directly into the urobox. 3. Allow 30 minutes for the sperm sample to liquefy and filter through the funnel into the test tube. After this period, remove the funnel and dispose of it in the trash together with the urobox. 4. Observe which number on the test tube aligns closest to the top of the sperm sample. If the top of the sample falls midway or more between two numbers, record the higher number. This will determine the number of dye drops you need to add to the sperm sample. If the sperm sample's top is below the number 1, which is etched on the conical part of the test tube, the sample is too small for an accurate test result. Turn the reagent bottle upside down over the test tube and carefully squeeze out the specified number of dye drops onto the sperm sample. Reattach the cap to the test tube and shake it well to mix the dye with the sperm sample. The mixture should now turn blue or purple. 5. Turn on the hot water until it becomes just too hot to comfortably touch. Fill a drinking glass to approximately 3/4 of its capacity with hot water (ensure it's not boiling) and attach the thermometer in the drinking glass. Once the correct temperature 48°C to 50°C is achieved, insert the test tube into the water. Record the time. Avoid placing the drinking glass near open windows or air conditioners to maintain temperature stability. Practicing this step prior to sample collection can be beneficial. 6. Sixty minutes after placing the test tube in the drinking glass, carefully remove it, dry the exterior with a towel or tissue, and then shake the test tube vigorously 4 or 5 times. This action is intended to ensure the dye is thoroughly mixed throughout the sperm sample, achieving even color distribution. 7. Place the white section of the color chart behind the sperm sample to compare its color. Hold both the test tube and the color chart approximately 7 to 10 cm (3 to 4 inches) away from an incandescent light source (avoid using fluorescent lighting). Slide the test tube across the row of colors on the chart to find the closest match, understanding that it might not be an exact match. Observe whether the closest color match falls within the Positive (+) group, indicating normal fertility potential, or the Negative (–) group, suggesting less than normal fertility potential. It's crucial to ensure that no fluorescent lights are on while assessing the test results to avoid any discrepancies in color perception. Interpretation Due to the test's expected color transition from dark blue to red and pink, individuals with red color blindness are advised against interpreting the results. If the color aligns with the Positive group, there is an 86% likelihood of normal sperm activity (20 million or more active sperm per milliliter of fluid), indicating favorable fertility potential. However, this does not assure pregnancy, as various factors influence fertility in both partners. Should pregnancy not be achieved within four months, it's recommended to seek medical advice. Conversely, if the color matches the Negative group, there's an 86% chance that sperm activity is below normal (fewer than 20 million active sperm per milliliter of fluid), making pregnancy less probable, though not impossible. In such cases, consulting a physician is advisable. A Negative result should not be interpreted as an impossibility of pregnancy nor should it be considered a justification for forgoing contraception. Questions and answers - Why does the kit contain material for two tests? The kit includes materials for two tests because sperm quality can fluctuate between samples from the same individual due to various factors such as activity levels, diet, environmental conditions, and other unknown elements. Therefore, the outcome of the first test is best validated by comparing it with a second test conducted after a minimum oneweek interval. Typically, the results of both tests will align. However, if there is a discrepancy between the two, it's advisable to seek a more detailed semen analysis in a medical laboratory to obtain an accurate evaluation. - How long should I abstain prior to the test? Refrain from ejaculating for a minimum of three days and a maximum of ten days prior to conducting the test. - Thirty minutes after ejaculation the majority of the specimen is still not liquefied. Should I wait longer? Yes, wait an additional 10 minutes. If, after this period, the sperm sample has not liquefied the test should be considered invalid and cancelled. It is advisable to consult with a physician in such cases. It is normal for a small amount of the specimen to remain on the urobox, and this should not affect the test's outcome. - The top of my specimen was closest to the number 2. By mistake I added 4 drops of test liquid instead of 2 drops. Should I continue the test? No, the result might not be reliable. Please discard this test and, after waiting three days, conduct another one with the second set of test materials provided. - What can cause a low sperm count or poor sperm movement? Exposure to excessive heat, such as through hot tub use or experiencing fevers, can negatively impact sperm quantity and quality. High fevers can influence test results adversely for up to three months following the illness. The consumption of illicit drugs, excessive alcohol, and smoking cigarettes can all lower sperm counts or impair sperm motility. Furthermore, certain medications can detrimentally affect sperm. Various conditions may lead to reduced sperm quality, but many of these can be treated successfully. If the condition is incurable, artificial reproduction techniques can often still be employed with success in most cases. - Can I collect the sperm sample in a condom? No, typical condoms are treated with a chemical that destroys sperm, making them unsuitable for collecting a sperm sample. However, non-medicated sheaths are availablefor this purpose. Consult your physician regarding where to obtain them. Additionally, it's important not to collect the sperm sample through withdrawal during intercourse, as the initial portion of the ejaculate, which contains the highest quality sperm, may be lost. - My sperm sample did not reach the 1 mark on the test tube. What can I do? Attempt the test again, this time with a longer abstinence period of 10 days. This extended duration may help increase the sperm sample's volume. If, after this second attempt, the sperm sample still does not reach the 1 mark on the test tube, it's advisable to seek further evaluation from a physician. SPERM FERTILITY CHECK ENG PDF

ELEAN MORIAN OIL ACIDITY FAST

€

Description: The fundamental classification of olive oil, including categories such as extra virgin, virgin, pure, etc., and the pricing of olive oil are contingent on its acidity level. A lower acidity level signifies the optimal health of the fruit, favorable harvesting conditions, and proper production and storage methods. The acidity of the oil is measured by the presence of free fatty acids expressed in grams of oleic acid per 100 grams of oil. A higher acidity number indicates a higher concentration of free fatty acids, which correlates with a deterioration in the oil's quality. The escalation in acidity is directly associated with processes of oxidation and rancidity. These issues stem from factors such as the degree of problems in the olive fruit (such as blight, freezing, bruising, or rot), the method of harvesting, milling processes, inadequate storage, and the blending of oils with older or degraded counterparts (such as pomace moil). Suggested use: The Elean Morian Oil Acidity Fast kit, developed by MenidiMedica Biotech Greece, is a rapid and user-friendly kit designed for the titration-based measurement of olive oil acidity. The kit includes all the necessary materials for conducting 10, 20, 50, 100, or 1000 tests. Technical performance characteristics of Elean Morian Oil Acidity Fast kit: - Measuring range: 0-1% acidity - Measurement accuracy: 0.01% (0.01 mL) - Analysis method: Titration - Sample size: 5.5 mL Storage: The kit is recommended to be stored at room temperature (18-30°C). It is essential to avoid exposing the kit to high temperatures and direct sunlight. Refrigeration of the kit is not advised. Method procedure: 1. Use the R1 syringe to add 5.5 mL of R1 reagent to the test vial. 2. Employing the SAMPLE syringe, add 5.5 mL of olive oil to the test vial. 3. Utilizing the 1 mL syringe, draw up a volume of R2 reagent equal to 1 mL and titrate drop by drop into the test vial, shaking each time. Cease titration when the color produced becomes a permanent pink or red after each shaking of the test vial. Calculation of acidity (with example): Fill the 1 mL syringe with 1 mL of R1 reagent. Titrate 0.12 mL of Reagent R2 into the test vial. Therefore, the acidity of the sample is twice the titration value. In the example case, it is calculated as 0.24% acidity. Acidity = V(R2) x 2, where V(R2) is the volume of R2 reagent titrated ELEAN MORIAN OIL ACIDITY FAST ENG IFU PDF

Giemsa Solution

€

Polychromatic solution of eosin, Methylene Blue and azure dyes - Used for staining in hematology, cytology and staining sections of hematopoietic organs in histopathology Introduction Polychromatic Romanowsky dyes are a standard in hematology of blood smears and bone marrow. Various sorts of Romanowsky dyes (Giemsa, May-Gruenwald, Leishman, Wright, Jenner and others) contain different ratios of methylene bluing reagent used as the cation component (and the reagent-related thiazine dyes, such as azure B) and eosin Y as the anion component. Cation and anion components interaction creates a well known Romanowsky effect that cannot be achieved if each component is being used individually. Purple color indicates the effect's presence. Staining intensity depends on the azure B content, as well as azure B to eosin Y ratio, while a few other factors affect the result of staining: working solution pH value and buffer solution, fixation method and dye exposure time. MenidiMedica Biotech Giemsa solution is used for differentiation of nuclear and/or cytoplasmatic morphology of lymphocytes, monocytes, granulocytes (neutrophils, eosinophils, basophils), thrombocytes and erythrocytes. There are various methods of using the Giemsa solution, and the so-called Pappenheim method is one of the most commonly used ones. The method is esentially the May-Gruenwald Giemsa method combined with the May-Gruenwald solution that stains cytological material (peripheral blood smears, cytodiagnostic puncture aspirates, diarrhea or secretion cells) or hematopoietic organs' sections. Along with the Pappenheim method, the Giemsa solution is commonly used for chromosomatic aberations detection in cytogenetics.

Quantitative eosin staining kit for the percentage measurement of live spermatozoa in semen samples GENERAL INFORMATION Sperm vitality is reflected in the proportion of spermatozoa that are “alive”. Sperm vitality should be determined in semen samples with less than about 40% progressive motile spermatozoa. Sperm Vitality Test uses the eosin staining technique to establishes the percentage of live spermatozoa. The technique is based on the principle that dead cells will take up the eosin, and as a result stain red. Sperm Vitality Test provides an accuracy check of the motility evaluation since the percentage dead spermatozoa should not exceed the percentage immotile spermatozoa. Sperm Vitality Test may help in assessing the diagnosis and the management of male infertility.

Tally the number of stained (dead) and unstained (vital) cells with the aid of a laboratory counter. 7. Evaluate 200 spermatozoa in each replicate, in order to achieve an acceptably low sampling error. 8. Calculate the average and difference of the two percentages of vital cells from the replicate preparations. 9. Determine the acceptability of the difference. 10. If the difference between the percentages is acceptable, report the average percentage vitality. If the difference is too high, make 2 new preparations from 2 new aliquots of semen and repeat the assessment. 11. Report the average percentage of vital spermatozoa to the nearest whole number. INTERPRETATION - Colourless spermatozoa: live spermatozoa - Red stained spermatozoa: dead spermatozoa Count between 100 and 200 cells and differentiate the living from the dead spermatozoa. Read results immediately, waiting too long will yield lower vitality percentages. It is clinically important to know whether immotile spermatozoa are alive or dead. Vitality results should be assessed in conjunction with motility results from the same semen sample. The presence of a large proportion of vital but immotile cells may be indicative of structural defects in the flagellum; a high percentage of immotile and non-viable cells (necrozoospermia) may indicate epididymal pathology. A semen sample is considered normal if 58% or more of the sperm cells are alive. LIMITATIONS OF THE METHOD Spermatozoa stained with Renata Sperm Vitality Test cannot be used for any further procedures. STORAGE Suitable for transport or short term storage at elevated temperatures (up to 5 days at 37°C). Store reagent between 2°C and 25°C. WARNINGS AND PRECAUTIONS All human, organic material should be considered potentially infectious. Handle all specimens as if capable of transmitting HIV or hepatitis. Always wear protective clothing when handling specimens. Sperm Vitality IFU ENG PDF

Quantitative measurement of Acidity in fats & oils Description The acidity level of edible oils and fats is determined by the amount of free fatty acids produced by the breakdown of triglycerides during hydrolytic rancidity. Since this change takes place under unfavourable conditions for the processing and preservation of fats, acidity serves as a fundamental measure of the authenticity of the product. This test is particularly critical in the refining of oils and fats, as it contributes to the evaluation of the processing cycle and the classification of products. Although it has comparable accuracy, this test is simpler to perform than the official AOCS Ca 5a-40 method. In samples with a pH below 7,0, the free fatty acids present react with a colour-producing compound, resulting in a reduction of the colour intensity. The extent of this reduction in colour is directly proportional to the concentration of acid in the sample, expressed as a percentage of oleic acid. Package contents 1 x 0.75 ml R1, 1 x 0.25 ml R2, 5 x 20 ml R3 Number of tests: 100 tests Ref.: 89491 Shelf life: 24 months from date of manufacture Storage & Stability: 2-8°C Sample collection instructions No preparation of olive oil sample preparation is required. For the analysis of samples such as solid fats, butter, margarine, cream, nuts, flours and other extracted fatty foods, it is recommended to follow the guidelines described in the enclosed 'Preparation of test sample for analysis of fatty foods'. This document provides guidance on how to properly prepare these specific samples for analysis and can be obtained from your supplier or from the manufacturer - MenidiMedica Biotech Greece. It will likely include information on techniques such as milling, homogenisation, extraction or other relevant procedures to ensure accurate and representative analysis of the fat content of these foods. Preparation of reagents Preparation WR: Add 150 uL. R1 and 50uL. R2 to one of 5 vials of 20 mL. R3. Screw on the cap of vial R3. The WR changes color to violet and is stable until the expiration date indicated on the outer label of the kit. Procedure - Wavelength: 546 nm - Blank: Air - Method: End Point - WR: 1 mL. - Sample: 20 uL. - Mix and incubate for 60'' (seconds) - Read results Reference values Linearity (for olive oil): 0,01-1,10 (expressed as % oleic acid) For other types of food, please inform the producer MenidiMedica Biotech Greece to provide you with the corresponding protocol with the following linearity towards this type of food. Note: For samples where the analyzer gives you an UPPER LIMIT value, then you should dilute your sample with OLIVE OIL DILUTOR (Ref. 89377, sold separately by MenidiMedica Biotech Greece) in a ratio of 1:1 or 1:5 and multiply the result given by the analyzer by 1 or 5.

Rehydrating/dehydrating agent of tissue and cytological samples Introduction Histology, cytology, and related scientific fields focus on examining the microscopic structure of tissues and cells. Achieving clear visualization of tissue and cellular structures requires precise sample processing. The histological sample processing involves several key steps, with three involving dehydration and subsequent rehydration. The initial step involves preparing the samples for infiltration, embedding them in paraffin, and then cutting the paraffin blocks into thin slices. In the second step, the samples are prepared for staining, and the final step involves mounting the samples on glass slides. Since most embedding media, like commonly used paraffin, do not readily penetrate samples containing water, it is essential to perform dehydration first to facilitate the infiltration process. Once the samples are embedded in paraffin, cut into thin slices, and mounted on glass slides, they maintain their integrity for a specific period. However, before staining, it is necessary to remove the paraffin and rehydrate the sections. Only then can histological dyes be applied for staining. A similar procedure is followed for cytological samples, with dehydrating agents, primarily consisting of alcohols. One widely used dehydrating agent is denatured ethanol, which serves as the primary component in MenidiMedica Biotech Histanol. Histanol is a transparent, colorless, and flammable liquid known for its rapid action and high efficiency. Product description Other slides and reagents that may be used in staining: - Fixatives such as MenidiMedica Biotech neutral buffered formaldehyde solutions (Formaldehyde NB 10%) - Dehydrating/rehydrating agent, such as MenidiMedica Biotech alcohol solutions - Clearing agents, such as xylene or a substitute agent on the aliphatic hydrocarbons basis - Infiltration and fitting agent, such as granulated paraffin - High-quality glass slides for use in histopathology and cytology - Differentiation agent, such as MenidiMedica Biotech Acid alcohol - Bluing agents, such as MenidiMedica Biotech Scott's solution or Bluing reagent - Covering agents for microscopic sections and mounting cover glass, such as MenidiMedica Biotech Eukitt - Cover glass, dimensions range from 18x18mm to 24x60mm - Reagent for nuclear staining, such as MenidiMedica Biotech Hematoxylin Harris - Counterstaining reagents, such as MenidiMedica Biotech eosin solutions Preparing histological sections for staining - Fix the tissue sample tightly (10% NB Formaldehyde), rinse with water and dehydrate through series of ascending alcohol solutions (Histanol 100). - Clear the sample with intermedium; in xylene or in a xylene substitute. - Infiltrate and fit the sample in paraffin - Cut the paraffin block to 4-6 µm slices and place them on a glass slide Hematoxylin and eosin (HE) staining procedure, progressive - Deparaffinize the section in xylene or in a xylene substitute - 3 exchanges, 2 min each - Rehydrate using 100% alcohol (Histanol 100) - 2 exchanges, 5 and 3 min - Rehydrate using 95% alcohol - 2 min - Rehydrate in distilled water - 2 min - Stain using Hematoxylin Harris - 3-5 minutes Note: In the case of subsidence in the solution or a formation of metallic glow on the surface, reagent should be filtrated before use. - Immerse the section in distilled or demineralized water until dye is no longer being released from the section - Make nuclei turn blue using Scott's solution or Bluing reagent - 1 min Note: Finish the process of bluing after the nuclei turn blue If no Scott's solution or Bluing reagent is available, rinse the sections under tap water for 3-5 minutes. - Stain with one of eosin contrast solutions until the section is optimally stained - 15 seconds - 2 minutes Note: Staining the sections in eosin alcoholic solutions causes intensive eosinophil color to show much faster (in under 15 seconds' time). Recommended exposure time for eosin aqueous solutions is 90 seconds to 2 minutes - Rinse under tap water - 2 min - Dehydrate using 95% alcohol - 2 exchanges, 10-15 dips - Dehydrate using 100% alcohol (Histanol 100) - 3 exchanges, 10-15 dips - Clear the section in xylene or in a xylene substitute Immediately after clearing apply an appropriate mount medium for covering/mounting on the section. If xylene was used, use one of mounting xylene-based media. If xylene substitute was used, use the appropriate covering agent for this case. Cover the section with a cover glass. Result Nucleus - dark blue Cytoplasm, collagen, elastin, erythrocytes - various shades of pink (when staining with Eosin Contrast the shade is red-pink) Note Time periods of staining processes are not entirely standardized and they approximately correspond to clinical and laboratory practical experience. Intensity of staining depends on the period of immersion in the dye. Real staining protocol depends on personal requests and priorities. Preparing the sample and diagnostics Use only appropriate instruments for collecting and preparing the samples. Process the samples with modern technology and mark them clearly. Follow the manufacturer's instructions for handling. In order to avoid mistakes, the staining procedure and diagnostics should only be conducted by authorized and qualified personnel. Use only microscope according to standards of the medical diagnostic laboratory.
