REGULATION OF FATTY ACID METABOLISM Introduction: Fatty acids are produced by acetyl-CoA by its transformation to malonyl-COA by various known as fatty acid synthases and this takes place in cytoplasm.Acetyl-COA is fuether transformed into various fats molecules taken from carbohydrates through a process known as glycolytic pathway.This pathway basically requires glycerol along with three fatty acid molecules to form a structure called as neutral fats or triglycerols.Two fatty acid molecules basically

Favism is a disorder. It’s caused by a lack of G6PD, and the lack of G6PD causes free radicals to roam free in your red blood cells, and therefore breaking them down and causing havoc in your blood. Unchecked, this could be a fatal problem. For example, primaquine, a medicine that helped regulate malaria, was deadly/ destructive to the healths of the people who had favism. That is because primaquine puts stress on your blood cells in order to make your blood a malaria-hostile area. However, when

One of the concluding sentences that Dr. Sharon Moalem directs toward her audience is, “[...] Our relationship with disease is often much more complex than we may have previously realized.” “Survival of the Sickest” delves into the theme of the way inheritance and genetic codes in our bloodlines allows fatal diseases to enter our body and the reasons for this happening. The author discusses various diseases and their origin, and includes facts as to how this disease is able to affect modern life

In the donor compartment, proliposomal formulation and control (drug suspended in sodium CMC) equivalent to 10mg of KTZ were placed separately. 30% v/v acetonitrile containing phosphate buffer saline (pH 7.4) was taken as receptor medium and kept under constant stirring upto 24 h. In order to avoid evaporation of the contents, donor compartment and sampling port are covered with aluminium foil. 500 µL of aliquots are drawn at predetermined

containing six animals each. For induction of lung carninogen BALB/c mice were given Urethane in all the group except normal control, twice a week for a period of 4 weeks by intraperitonial injection[1]. Group I serves as normal control receive normal saline. Group II serves as Disease control receive Urethane at a dose

An important part in the brain involved in memory, decision-making, and emotional responses is called the medial amygdala (MePD). The MePD is located within the temporal lobes of the brain and plays a major role in the life of complex vertebrates. MePD receives information pertaining to reproductive behavior from the hypothalamic portion of the brain (Johnson et al., 2008). The MePD is numerous in neurons and astrocytes. Astrocytes are neuroglial cells with many branches, or processes, that originate

Synergistic Analgesic, Anti-Pyretic and Anti-Inflammatory Effects of Extra Virgin Olive Oil and Ibuprofen in Different Experimental Models in Albino Mice. Walla’a A. Osman1, Dina A. Labib1, Mona O.

with adenosine nucleotides such as ATP, ADP, and AMP. After collecting data, the results show that there was little to no difference between bugs engorging on blood and ATP. Also, the same effect applied to low concentrations of ATP and phosphate-buffered saline when offered to male bed bugs. This experiment revealed that bed bugs engorged more than 80% of ATP, 40% of ADP, and less than 20% of AMP. Which means that ATP had the highest effect on bed bugs than ADP or

were withdrawn from three healthy volunteers with informed consent in heparin test tubes. After centrifuging at 1250 g for 10 minute, the plasma portion and buffy coat were removed and the remaining erythrocytes were washed 3 times using phosphate-buffered saline (PBS). The washed packed RBCs had a hematocrit of about 80%. RBCs loading with FVIII Stepwise hypotonic dialysis was used to load factor FVIII (Lyophilized powder from human plasma produced by Biotest, IBRF) in RBCs. Two ml of washed pack

volume of double-distilled water. The precipitate was dialyzed and used for enzyme purification using column chromatography. The dialyzed sample was loaded on DEAE-cellulose column, which was equilibrated previously with the buffer A (50 mM sodium phosphate buffer, pH 7.4). The column was washed with the five bed volumes of buffer A, and the enzyme was eluted with buffer A

cervical dislocation. Liver tissues were grossly examined and divided into three parts, the first part was preserved at -20°C for tissue biochemical investigations, the second part was preserved at -20 °C in phosphate buffer saline (PBS) for Comet assay, and the third part was fixed in 10% neutral buffered formalin (NBF) for

Following successful studies using TB-500 by researchers at Wayne State University School of Medicine to together with the Kresge Eye Institute in Detroit, Michigan, RegeneRx Biopharmaceuticals, Inc published the results of this study which showed that thymosin beta 4 was an active corneal wound healing and anti-inflammatory agent Thymosin beta 4 is a protein that naturally occurs in all cells except in erythrocytes. Despite this protein being a key monomeric actin-sequestering peptide within cells

21 Fresh semen samples were diluted with phosphate-buffered saline (PBS) to 2x106 sperm/mL. Fifty µL were incubated with 100 µL lysing reagent for 15 seconds and then 2 mL of PI was added and mixed with tube. Tube acquisition was done by flowcytometry immediately after staining. The intensity of its emission

Remove the fixative. 7. Wash the tissues two times with phosphate-buffered saline. Discard the supernatant. 8. Stain the spheroids with eosin, if desired. An eosin stain will make it much easier to see and handle during the rest of the procedure. 1.2 Create a Plug of Spheroid-Containing Agarose Gel After the spheroids

In this three-week long experiment conducted in the Bio 13 Lab, we were able to analyze a single nucleotide polymorphism (SNP) in our own genomic DNA and then determine our genotype at this specific SNP. In week one, we extracted genomic DNA from our cheek cells with swabs and prepared our DNA for PCR (Polymerase Chain Reaction) that would amplify the region with the intended SNP of interest. After one week and after the PCR was run outside of the lab section, the resulting PCR product was purified

INTRODUCTION Carbon tetrachloride (CCl4) - an organic industrial solvent used in industry – is a vigorous carcinogenic agent that may create dysfunction of lung, liver, kidney and nervous system (1, 2). After being absorbed from gastrointestinal system, respiratory system and skin CCl4 is metabolized by cytochrome P-450 and exerts its toxic effects via its metabolites trichloromethyl free radical and trichloromethyl peroxyl radical (1-3). These free radicals interacts with fatty acids of lung cell

medium was removed and stored for TNF-α protein concentration analysis using the Elisa quantikine immunoassay kit for mouse TNF-α (R & D Systems, Minneapolis, USA ), following the manufacturer's instructions. Cells were washed with cold phosphate buffered saline solution (PBS) and lysed with lysis buffer for the determination of total protein concentration using the bicinchoninic acid-based BCA kit (Thermo Fisher Scientific, Waltham, USA), with bovine serum albumin (BSA) standard according to the

In accordance, a total sample of … orthodontic patients (… females,… males), had been selected at random from a group of total … orthodontic patients, using a random table method. Calculation of sample size was based on determination of the power of statistics of the study. The sample was selected from patients seeking orthodontic treatment in the Outpatient

INTRODUCTION Monosodium L- glutamate (MSG) is a major flavor enhancer used as a food additive; its concentrations vary in different foods (Walker et al., 2000). Nowadays, the safe concentration of MSG in foods and its toxicity in human is still a controversial issue (Beyreuther et al., 2007). In animals, MSG at higher doses was demonstrated to be a neurotoxic salt that could alter the hypothalamic-pituitary-adrenal axis (HPA) and damage neurons in the hypothalamic nuclei. The ability of monosodium
