14:32 Ma’am I love your lessons, just a little potential mistake that I spotted here. Cholesterol doesn’t affects the fluidity of the cell membrane, it only decreases the permeability to small polar molecules like water, permeability≠fluidity. Cholesterols can actually help maintain the fluidity when temperature drops down, it keeps phase transition at bay. That’s what I’ve read from the book “Molecular biology of the cell, Alberts”

Hi. Thank you for your comment and question. Actually, Cholesterol content in the membrane is extremely important in regulating the fluidity of the plasma membrane, especially with temperature changes. At High Temperatures: Cholesterol tends to stabilize the membrane by making it less fluid. It restricts the movement of phospholipids, which can prevent the membrane from becoming too permeable or leaky. At Low Temperatures: Cholesterol helps to prevent the membrane from becoming too rigid by preventing the phospholipids from packing too closely together. This ensures that the membrane remains somewhat fluid, which is essential for proper cell function and for maintaining membrane proteins’ mobility and function.

Hi Dr Fatima, just wanted to say that you have a knack for explaining complex topics well! I remember struggling with the movement of the ribosomal subunits back in my first year of undergrad, and I wish I had someone like you to make it clear! Currently revising cell bio again to refresh my memory for grad school entrance exams :) Thank you again!

Why we taken c value is negative on that equation
@biologybasicsАй бұрын
The value of c can be positive or negative based on whether the intercept is made on the positive or negative side of the y-axis, respectively. You can force intercept to pass through "zero" to get a non-negative value.

Thank you so much for this informative video. I would like to ask does calibration need to be done even if I added a scale bar via Zen Black? I have images with 20X, 40X, and 63X. If I click global, will it apply to every image? How could I solve that problem? In addition, does the calibration is necessary for the intensity measurement? Thank you so much.
@biologybasicsАй бұрын
If your image has a scale bar through Zen Black then you should be able to calculate it's size without going through calibration. Instead, you can input that information in ImageJ and hit global to apply to all the images. You have to remember to change the calibration for each set of magnifications though and reset global accordingly. I would start by organizing the images into folders for each magnification e.g. all the 20x images together, all the 40x images together etc. Next, you would need to know what the scale bar provided by Zen Black is equal to in each case. I believe you should be able to find that information on the image bar itself. You would then open one of these images in Image J. Follow my calibration instructions and in this case measure the scale provided by ZenBlack and measure it in pixels, then set it to the measurement in uM shown in the image by ZenBlack. You can set it to Global and analyze ALL images with the same magnification taken by the same program. You would then repeat these steps for each set of images at different magnifications. To just measure intensity you do not need any calibration. Hope this helps.

My wife and mother to our twin 9 year old boys is facing palliative care for stage 4 cervical cancer here in the UK. Is there any way she could take part in this trial and access this incredible drug? Happy to pay whatever possible.
@biologybasicsАй бұрын
I am so sorry to hear what your family is going through. It is hard to watch someone you love go through this terrible disease. Unfortunately, our drug is not at the stage where we can use it for human trials yet. However, there are many new targeted therapies coming each week, one of which may help and/or provide her better quality of life. I hope the doctors you are working with can find other trials that she may be eligible for to give her that chance to be with you and her kids for a long time. You and your family will be in my thoughts and prayers.

I wanted to suggest a small clarification regarding polar bonds in water. Polar O-H bonds occur due to the electronegativity of oxygen, a result of its positively charged nucleus and incomplete valence shells. It is not due to its size/weight/mass.
@biologybasics5 ай бұрын
Yes. Ofcourse. The polarity is indeed from the electronegativity of oxygen. However, the mass/ size of the oxygen helps in keeping that electronegativity since it "hogs" the electrons longer in it's own valence shells.

Have you input the gene ontology results in reactome to see what comes up? Sometimes individual genes may not be directly related to a process but a combination of them together can indeed affect the pathway of interest indirectly.
