Five Tips for the Postgraduate to Start Publishing

fivetipsPost graduation can be a daunting task with a lot to imbibe in very little time. In ophthalmology, the science is changing ever so rapidly that a three-year residency period is almost too little to grasp the nuances of the subject. In addition to learning examination skills, you have to learn surgical skills and read literature to keep yourselves updated. Amongst all this, how do you find time to publish papers during residency? Does it really matter whether you publish any papers during this time? Are there any advantages you score over your peers if you manage to publish a few papers? Dr. Sabyasachi Sengupta shares his tips for the postgraduates. Click here to read

Brolucizumab is a humanized single-chain antibody fragment that inhibits all isoforms of VEGF-A. It is the smallest of the anti-VEGF antibodies. Brolucizumab has a molecular weight of 26 kDa, compared with 48 kDa for ranibizumab, 115 kDa for aflibercept and 149 kDa for bevacizumab.

It is possible to concentrate brolucizumab up to 120 mg/mL, allowing the administration of 6 mg in a single 50-mL IVT injection. On a molar basis, 6 mg of brolucizumab equals approximately 12 times the 2.0-mg dose of aflibercept and 22 times the 0.5-mg dose of ranibizumab. Thus this drug has potential advantages in the treatment of ARMD. Assuming comparable half-life, higher molar doses of drug may be cleared more slowly from the eye, thus prolonging duration of action. Small molecular weight + higher molar doses + high drug concentration gradient between the vitreous and retina may support support superior drug distribution into the retina.

Authorship by Dr. Bipasha Mukharjee

AuthorshipPublications represent the three ‘R’s of modern times– recognition, respect and revenue, for anyone in the field of science and research. Authorship has become the currency of the current generation and a measure of one's status in the international scientific community. The number of papers published, the journals in which they are published, and their ranking on the list of authors are all crucial when it comes to promotions, funding and market value in the employment exchange. The ‘publish or perish’ culture has become our survival mantra. However, as Rennie, Deputy Editor of the Journal of the American Medical Association put it: “the coin of publication has two sides: credit and accountability.”  Read more...


How to Present a Scientific Paper by Dr. Jyotirmay Biswas

micpodiumIt's true that Computer is indeed a boon to a scientist making a presentation. Yet it is important that the presenter himself is adequately prepared for a good presentation. He needs to plan carefully and follow a few basic steps.
A good scientific presentation starts from the time a paper is conceived. If you want to present a good paper, ensure that the concept is good, well thought, designed aptly, results well analysed and valid conclusions are made. You should have your ground work done and write the draft of the paper, before embarking on a presentation. A well-written draft will provide the frame work of a good presentation. Read more.....


A(VAST)IN Saga by Dr. Bikramjit Pal & Dr. Parthpratim Dutta Majumder

Vascular endothelial growth factor (VEGF)-A is a key mediator of angiogenesis. The discovery of VEGF-A, like many other major discoveries in medicine, happened partly by observations and partly by chance. Napoleone Ferrara and his team were working on a population of non-hormone-secreting cells from the anterior pituitary of cows. (1) One day Ferrara mixed some isolates from cultures of follicular cells with endothelial cells.  Read more....
