Question

Hello to all my fellow Biologists.
I have resorted to posting this question as my last desperate attempt to find a place for myself in the world of biotechnology.
I am a first class student with relatively good grades (GPA 3.77/4.00) in BSc. of Biotechnology (Hons), excellent extra-curriculars and competitions under my belt, 6 months of work as a Field/Research Assistant and 4 years of previous work experience in events management. I have experience in the microbiology, molecular biology, antivirals, nutraceuticals and cell culture disciplines. I have also taken a great liking to scientific communication and create visual content to make biology simpler for the Layman, both bother and in my own time.
Despite all this, I haven't had a single postgraduate application succeed for the last 2 years. And though I do understand there is high competition for available spots, I also wonder what I may be lacking despite some telling me I have an "impressive CV" and can do a direct PhD.
It is unfortunate however that my family is not doing financially well, therefore I can only afford opportunities with a scholarship or that are work/salary-based. Perhaps this narrows available opportunities but regardless, studentship scholarships have very evidently not opted for me, simply because "there were too many applicants this time around". Perhaps lacking funds is not enough of a criteria? (Hint of sarcasm).
Additionally, I was born and raised in the UAE (I do not get citizenship), therefore I am also looking for a potential country to eventually settle down in while doing the work I love.
I would greatly appreciate if anyone would know of opportunities I may be able to apply for like fully funded PhDs, or skilled/summer programs and workshops/internships, or even Research or Lab assistant positions you or someone you know may be looking for, because unfortunately, I'm 2 rejections away from being completely out of options.
I would greatly appreciate any input you may have or can share with me! I have also added my CV for your reference.
I don't want my impression of the field I love to be tainted with nothing but rejections, and to settle for a job outside our field simply because I had no other choice.
I look forward to hearing from you all.
Sincerely,
Zahraa Ozeer

Dear friends and colleagues,
there is a very important resource on the web that is "Atlas of Genetics and Cytogenetics in Oncology and Haematology". The Atlas is a peer reviewed on-line journal / encyclopedia / database established in 1997 that collects data about cancer genes, solid tumors, leukaemia and other resources. It is in open free access for readers and there are no fees for the authors.
I'm searching volunteers and collaborators that would to write with me reviews about single genes involved in cancer.
I have published several papers so far and I believe that Atlas is a very valuable tool for us researchers, scientists and scholars.
I invite you to visit the Atlas website at http://atlasgeneticsoncology.org/index.html for more information. Here is my latest article published http://atlasgeneticsoncology.org//Genes/GC_EEF1B2.html to show you my working method. Anyone wishing to collaborate with me to write a specific review on a gene can tell me as well.

Answer
I have research and interests in medical genetics on a less laboratory research results level. I rely on the scientific research in Atlas of Genetics and Cytogenetics in Oncology and Haematology nonetheless. Congratulations on your ambitious and important research project! Best regards.

I am interested to have some cases/examples where scientists come out with an efficient drug against a disease marker (successful clinical trials), although at the end they realized that the cost of developing and marketing that drug was too high to be afforded and covered by most of health insurance systems therefore they decided to quit the project without providing this drug to patients who needed it. Or cases when the project was stopped because at certain point the scientists realized that the cost of production of the drug was very high and the number of patients to whom this drug was targeted wasn't big enough to cover the research/development costs (orphan drug). I know that this is not common because usually no one would do a research without predicting the financial aspect that's why I am asking for your help, if you ever encountered such a case.
I need this information to moderate a debate about biotechnology and society, so if you have another interesting topic, I would really appreciate your suggestions.
Thanks in advance!

A big issue in antibiotic drug research and development these days has to do with the economics of introducing a novel antibiotic into the market when cheap generics are already available. The new drug may be better in some sense (e.g. fewer bacterial strains are resistant to it, or it is less toxic than the older drugs), but the hospitals won't use it very much because it is more expensive, and they won't be able to get sufficiently reimbursed by the insurance companies. Or antibiotic stewardship dictates that the new drug should be "saved" for use only when the cheaper drugs fail. As a result, companies that have completed the clinical trials and manufactured the drug can't sell enough to cover their costs. For some small companies recently, this has caused severe, even terminal, financial hardship. There is legislation pending in the US Congress to try to address this issue, because it is stifling the discovery, development, and use of new antibiotics to address the issue of drug resistant bacteria.

Does anyone have experience in measuring superoxide dismutase (SOD) using RANDOX reagents kit in follicular fluid? We tried to make measurements of different dilutions of follicular fluid, but we allways get zero as result.
Any idea?
Relevant answer
Answer
Dear Pavel.
We didn't try to analyze the serum of the same patient, but we measure SOD in serum by this method in routine and results are always OK.
Maybe is also relevant that we measured glutathione peroxidase (GPX) and total antioxidant status (TAS) on the same analyzer from the same manufacturer in the same follicular fluid and we got good results.

What is your favourite method to measure the aortic root and left atrial dimensions by 2D transthoracic echocardiography ?
2D or M-mode ?
M-mode in PLAX or PSAX ?
Relevant answer
Answer
Classically, the aortic root diameter and the left atrial antero-posterior diameter are measured from m-mode in PLAX. The advantages are being reproducible, high temporal resolution, wealth of published data, and no need for associated ECG recording to detect the systole and diastole. This method is applicable in most of patients. However, in some patients we may need to measure from m-mode PSAX or from 2D. In case we thought the left atrium is not normal we may need to measure the LA area or volume as the antero-posterior diameter represents a single dimension and not representative of actual LA size (particularly in dilated atria).

Hi
If i dissolve fibrinogen into a plasma (bovine) with anticoagulant (herparin/EDTA or citrate) will this prevent me from forming fibrin gels when mixed with thrombin? Will this anticoagulant in solution stop the fibrinogen - thrombin interaction required for fibrin gel formation. 
Can one buy plasma without anticoagulant?
BW
Relevant answer
Answer
Hi Rob
Citrate is the recommended anticoagulant for plasma to be used in coagulation tests. 
By definition, plasma has to be anticoagulated – if it isn’t, the blood clots and you end up with serum, which is deficient in clotting factors.

I willl make a carbonate and bicarbonate determination through volumetric titration with an acid and some indicator.
But I want to know some document or article in which I can find the interferences that I could have doing that analysis.
Thank you so much for your time and help
Have a nice day (or nit´)
Relevant answer
Answer
What you are in fact measuring is the alkalinity of your solutions. From which you can calculate your carbonate and bicarbonate concentrations. But the alkalinity consists not only of the carbonate and bicarbonate concentrations. 
Alk = [HCO3−] + 2[CO3−2] + [B(OH)4−] + [OH−] + 2[PO4−3] + [HPO4−2] + [SiO(OH)3−] − [H+] − [HSO4−]

How can we make the choice of wavelet type and decomposition level (DL) for any non stationary signal eg, PPG.
Relevant answer
Answer
For deciding the type of mother wavelet, you look for two key characteristics, these are: 1) shape of the mother wavelet. Ideally, it should look like the signal you want to represent. Example: coif1 i.e. coiflets 1 better represent the oscillatory nature of PPG signal. Refer: http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=7359311&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D7359311
2) the bandwidth of the mother wavelet. This decides how much your wavelet will spread.
Now deciding the number of decomposition levels completely depends on the minimum sub-band you want the signal to be represented. Example: For a signal of sampling rate = 1000 Hz if you want to see the signal within < 30 Hz. then, the DL using DWT can be 4. Refer: http://users.rowan.edu/~polikar/WAVELETS/WTpart1.html

  1. How would you make a solution or ointment (or otherwise) containing sucralfate where the sucralfate molecules are able to penetrate the skin?
Relevant answer
Answer
Transdermal drug delivery is not a trivial matter.  Drugs chosen for transdermal delivery are generally quite small molecules that are active at very low doses.  Sucralfate just isn't the kind of drug that suggests itself for transdermal delivery.
When applied to a mucous membrane, or indeed an ulcer on a mucous membrane, sucralfate probably doesn't penetrate at all.  It would be even less likely to penetrate intact skin.  So, why do you want to formulate an ointment or solution containing sucralfate, I wonder?  The only way in which you will get it to penetrate would be by seriously disrupting the integrity of the skin with a solvent such as dimethyl sulfoxide or sodium lauryl sulfate.  I wouldn't want that doing to my skin!

I need to find the most suitable process for production of an ADC "ado Trastuzumab emtastine(KADCYCLA)". Approximately 1500kg/L per annum.

Answer
I'd say it depends on the workup (batch or continuous) and if you can maintain a sterile production line for a longer time and what you'd do if there is a problem (technical or sterility). Maybe 2 or 3 batch reactors, run in parallel or alternated/time shifted may get you on the safer side.

There is some evidence of lead crush with subclavian access, but there is little evidence of lead erosion via axillary and cephalic routes. Is that really correct?
Relevant answer
Answer
The question has been asked many times and in different forms.
The approach using a cutdown to introduce the lead directly or with guidewires and dilators into a vein that is somewhat small is superior to subclavian or axillary venipuncture not only in terms of safety for the patient (no pneumothorax, no hemothorax), but also in terms of lead longevity.
See this report by Dr. Parsonnet and Roelke. Interestingly, Dr. Parsonnet was one of the first authors who reported on the use of peel-away introducers.
Pacing and Clinical Electrophysiology
Volume 22, Issue 5, Article first published online: 30 JUN 2006
Dr Furman and Gross and their co workers described a similar problem with defibrillator leads in
Lead fracture in cephalic versus subclavian approach with transvenous implantable cardioverter defibrillator systems.
Gallik DM1, Ben-Zur UM, Gross JN, Furman S.
Pacing Clin Electrophysiol. 1996 Jul;19(7):1089-94
I hope this helps. The references are by no means exhaustive but from very well respected sources, two of the founders of the Hearth Rhythm society, then called "NASPE".
It really pays in the long run to learn to do cephalic cutdown and to use it as your preferred approach.
Thank you,
