The aim of the experiment was to test what effects that ethanol solution has on the membrane permeability of B. Vulgaris. The B. Vulgaris samples were approximately 1cm3. They were kept the same size to ensure accurate results. A control test was conducted in distilled water to obtain a result to compare. The ethanol treatments were 40% and 70%.
Serum GOT activity was measured colorimetrically. Non-haemolytic serum was incubated with a buffered mixture of L- aspartate and α- oxoglutarate at 37oC for 12.6 minutes. The initial absorbance was recorded 1 minute after addition of the serum sample and at 1 minute interval thereafter for 3 minutes. The mean absorbance per minute (Δ A/minute) was recorded and used for the calculation of enzyme activity. The absorbance was read at U.V.
Among them 20 are normal healthy individuals and 20 are patients with OSCC. Informed consent was obtained from the patient before sample collection. 5ml of fasting venous blood was collected and centrifuged in 3000rpm for 10 minutes. Then serum was separated and then it is analysed for serum cholesterol by Cholesterol esterase-Oxidase method, Serum triglycerides by colorimetric enzymatic method, HDL-c by Phosphotungtic acid method, LDL-c and VLDL-c were calculated by Friedwald’s formula. Results: There is a significant increase in LDH (p<0.005) levels in OSCC patients when compared with healthy controls, by the influence of OSCC on LDH metabolism.
The urinalysis test records data based on the color, appearance, pH level, protein, glucose, specific gravity, ketone bodies, sediment and casts, bilirubin, and phenylketonuria that’s observed in the urine. Urinalysis can be helpful in detecting a range of disorders, such as urinary tract infection, kidney disease, and diabetes. Abnormal results can indicate a form of disease or illness. For instance, urinary tract infections can make urine appear cloudy. Overall, urinalysis is beneficial in terms of assessing one’s health, diagnosing a medical condition or illness, and the monitoring of a medical condition.
To prepare the solutions a 70% ethanol solution was used to make 40%. This was calculated using the C1V1=C2V2 formula. A photo spectrometer was used to measure, in arbitrary units, the change in membrane permeability of the B. Vulgaris cells. To begin, the B. Vulgaris samples were put into vials containing the distilled water, 40% and 70% Ethanol
Referring to Table 1, the reactants for each run were transferred to an Erlenmeyer Flask (250 mL) via a buret. Using a precision pipette, the volume of I3- required for each run was carefully extracted and poured into the flask containing all of the reactants. Immediately after the Iodine solution was placed in the flask, the LabQuest began collection data. Meanwhile, a small portion of the solution, was used to rinse the cuvette, then using a disposable pipette a small amount of the solution was transferred to the cuvette (approx. ¾).
The slides were placed for 2 hrs at 4 °C in a lysis buffer containing (2.5 mol/L NaCl, 100 mmol/L Na2EDTA, 10 mmol/L Tris, [pH 10] and a freshly prepared 1% Triton X-100 and 10% Dimethyl sulfoxide were added to the buffer just before use). Next, slides were covered and incubated for 20 min at 4 °C with electrophoresis alkaline buffer containing (300 mmol/L NaOH, 1 mmol/L Na2EDTA [pH > 13]) in the electrophoresis chamber. This step allowed DNA unwinding and the expression of alkali-labile DNA damage sites. Electrophoresis was performed for 30 min at 25 V and 300 mA. DNA from undamaged cells did not migrate and appeared circular while, DNA from damaged cells migrated to the anode and appeared as a comet.
After incubation, 200 µl of 100% ethanol was added to the lysate. The sample was then washed and centrifuged following the manufacturer’s recommendations. Nucleic acid was eluted with 100 µl of elution buffer provided in the kit. Oligonucleotide Primer. Primers used were supplied from Metabion (Germany) are listed in table (1).
Abstract In this experiment, the reaction kinetics of the hydrolysis of t-butyl chloride, (CH3)3CCl, was studied. The experiment was to determine the rate constant of the reaction, as well as the effects of solvent composition on the rate of reaction. A 50/50 V/V isopropanol/water solvent mixture was prepared and 1cm3 of (CH3)3CCl was added. At specific instances, aliquots of the reaction mixture were withdrawn and quenched with acetone. In addition, phenolphthalein was added as an indicator.
The reaction that occurs can be investigated via the adding of the liver extract which contains the arginase to urea concentrations and distilled water. The amount of urea formed is determined via spectrophotometric analysis α-INPP. The urea produced was known via the color reaction with the α-INPP, it is the reagent used for the colorimetric determination of urea. (Barry J, et al. 1984).
32 100 μL of afore-prepared sample solution and the mixed reference standard were diluted 100 times with ethyl acetate. 50 μL of these dilution solutions were separated on the TLC plate coated with SNISG. The plate was developed with petroleum ether: ethyl acetate (4:1) and the movement of solvent was usually controlled at 1 cm from the upper edge. After completion, the plate was dried until no solvent smell remained. It was sprayed with an ethanol solution containing 10% sulfuric acid, and heated at an infra-red drier until obvious color came up, as shown in Fig.2 (B.ab).
The absorbance was read at 0 seconds, at 30 seconds, at 60 seconds, at 90 seconds and at 120 seconds. All the absorbances were remained 0 for the blank. After 120 seconds, the blank was then removed, and the appropriate amount of enzyme Tyrosinase (0.40 mL) was measured and added into the blank (cuvette #1) using the micropipette P-1000 according to the table 2. The final volume in the cuvette was 3mL. The cuvette contained the enzyme sample was wiped off with a KimWipe and was placed into the sample compartment of the machine.
Urinalysis: Dark yellow and cloudy, protein 28 mg/dL, positive for casts, positive for red blood cells and white blood cells, positive for glucose and ketones. What do you think is the origin of W.A.’s septicemia? Septicemia is an infection of the blood, also known as bacteremia or blood poisoning. The most common infections that lead to septicemia are: urinary tract infections, lung infections, such as pneumonia, kidney infections, and infections in the abdominal area. I believe the origin of W.A.’s septicemia is her kidneys.
