Hello Doctor! I was diagnosed with HTLV-1, I have hyperthyroidism, osteoarthritis in my spine and osteoarthritis in my knees (I had surgery on my spine and a knee replacement). Do these bone problems and hyperthyroidism come from HTLV-1? I am 64 years old and female! A hug from Brazil!

I want to ask a question. My English skill is not enough to understand . It could be silly question sorry . I am trying to learn statistics . I would love to do statistics of my researches my own . I want to do a research about "Mortality and complications after percutaneous endoscopic gastrostomy)PEG): a retrospective one-centered study" My universe is 908 PEG . After excluding criterias I dont know how much will stay but probably around 600 cases I want them all. How can I calculate for that retrospective research sample size. 1-After PEG minör complication rate : %18-38 major complcation %2-4 2-After PEG mortality rate in 30 days : %3-23 I want to do multiple regression analyses . I have 2 dependent variables "mortality after peg " and "complications after peg" I have 31 independent variables. I do calculate at GPower . F test- Linear multiple regression : fixed model, r2 deviation from zero: A priori Effect size 0.15 , a 0.05 B: 0.95 number of predictors 31 Sample size 264. ***My question is this how can ı find effect size? Do you suggest me any other advice for my research sample size calculate ? Thanks for helping and sorry for baby english and long question.

Hi Maame Adwoa, please i have a malaria vaccine to analyse the protein content. I have the Bradford Protein kit from thermofisher and the Albumin standards for the curve. can you help me with how to go about it?

Very nice presentation

Hi, thanks for the video. Please, I have a question: I will like to ask a question about cell treatment experiment with a test drug for 72 h. In such an experiment, do I have to add my drug once and incubate for 72h then check the cell viability or I have to remove the drug solution and replace with the same drug and concentration after each 24h to avoid wrong readings due to degraded drug in wells or evaporation? Please any other person reading the comments can also reply me if you have the correct answer to my question. Thank you

hi thank you for your explaination. I have a question, if I measure dose dependency, in specific, I measure basal value of each well for 10 mins, and then add agonist and measure for 30 mins more. Then its supposed to have many points, then how should i choose value to make Z' factor?

I am a complete novice with ELISA but i need to run some blood tests that the UK does not offer, im going to buy all the equipment to conduct the following tests: MSH TGFB1 VEGF MMP9 C3A C4A Can you recommend a good book for the protocols and what elisa tests would be appicable for these tests (dircect/indierct etc.....) The top one is melanocyte stimulating hormone and i need to see a quantity not just sample presence in all of them Thank you, great videos

How do you adjust the gain?

Thank you so much for this practical lecture for university students like me who cannot have the condition and biotechnological facilities to practice. I wish you all the best in 2024, Madam!

does the volume of the samples have to be constant

Really helpful thank you !

Why do we need to be able to do such calculations? In order to maximize all available storage space most solutions are stored in a concentrated form (known as stock). These solutions are then diluted to the required strength as and when required. This also means the same solution substance may be used for a different range of needed concentrations.

Thanks for the information. Love it

Great video 👍

keep up the goodwork. I hope someone there's multiple of someone like you in this world. You keep the world turning

Thank you! ❤️

What is a good H-index? Hirsch suggests that after 20 years of research, an h-index of 20 is good! It means that you have 20 publications with at least 20 citations. 40 is outstanding, and 60 is absolutely exceptional.

I struggled to listen to it due to the music which is a shame as sounds like it may have been useful 😢

Other terms used to describe water quality in the lab includes: MQ/MilliQ water for type 1 water; Elix water for type 2 water and RO or demineralised water for type 3. Note that distilled water is water that is clarified through heating the water until it enters vapour form, and then cooling the water back to liquid form. Most labs do not use this method of clarification, preferring to use reverse osmosis, due to its greater efficiency.

Of course it is obvious that we do not appreciate qualities and the cost that it rather saves.

you saved my life man

Thank you!!

Fun fact: a typical adult has a blood volume of approximately 5 liters. Females and males have approximately the same blood percentage by weight.

Hi Adwoa Could you explain the interpreting Elisa result a bit more Do you have one-2-one tutorial?

Bold woman, magnificent

Note: some labs avoid using antibiotics in their Media as they don't want to risk masking low level infection or worse, facilitate the emergence of antibiotic resistant strains. Get more comprehensive knowlege via this article from pubmed: www.ncbi.nlm.nih.gov/pmc/articles/PMC7149418/pdf/main.pdf

I want to use artificial intelligence to come up with guide RNA sequences and target sequences in Pam sequences. but i also want a way too verify that the artificial intelligence, aka chat gpt 4 is actually correct. What tools can I use to verify findings? Chop chop is incomplete and only provides target sequences etc.

Amazing!

Informative video. I would like to ask a question about detection limit for ion selective electrodes (ISE). Have you worked with ISE before?

Hi. My mom was recently diagnosed with this virus (HTLV-1) and now has complete paralysis of her lower extremities. Is there a group that specializes in this advancement of the virus?

A poem by PHILLIS WHEATLEY upon seeing a young African Painter's (S.M.) work: To show the lab’ring bosom’s deep intent, And thought in living characters to paint, When first thy pencil did those beauties give, And breathing figures learnt from thee to live, How did those prospects give my soul delight, A new creation rushing on my sight? Still, wond’rous youth! each noble path pursue, On deathless glories fix thine ardent view: Still may the painter’s and the poet’s fire To aid thy pencil, and thy verse conspire! And may the charms of each seraphic theme Conduct thy footsteps to immortal fame! High to the blissful wonders of the skies Elate thy soul, and raise thy wishful eyes. Thrice happy, when exalted to survey That splendid city, crown’d with endless day, Whose twice six gates on radiant hinges ring: Celestial Salem blooms in endless spring. Calm and serene thy moments glide along, And may the muse inspire each future song! Still, with the sweets of contemplation bless’d, May peace with balmy wings your soul invest! But when these shades of time are chas’d away, And darkness ends in everlasting day, On what seraphic pinions shall we move, And view the landscapes in the realms above? There shall thy tongue in heav’nly murmurs flow, And there my muse with heav’nly transport glow: No more to tell of Damon’s tender sighs, Or rising radiance of Aurora’s eyes, For nobler themes demand a nobler strain, And purer language on th’ ethereal plain. Cease, gentle muse! the solemn gloom of night Now seals the fair creation from my sight.

"The world is a severe school master, for its frowns are less dangerous than its smiles and flatteries" - Phillis Wheatley The idea that African people were intellectually inferior was a justification for slavery. The legacy of that malicious and terrorising publicity, still lingers.
