Unusual life cycle and impact on microfibril assembly of ADAMTS17, a secreted metalloprotease mutated in genetic eye disease

Posted by in categories: biotech/medical, genetics

Need to share this with a few folks researching glaucoma disease and treatment/ mutation reversal.


Elderly are frequently hospitalized due to their age-associated organ degeneration, the presence of co-morbidities, and their susceptibility to adverse insults. Alterations in functional status often occur during hospitalization, and the degree of functional decline can parallel the severity of illnesses. For older persons, gauging their pre-morbid and in-hospital functional status facilitates treatment planning and potentially functional restoration1,2,3. While the identification of risk factors or markers of poor pre-morbid and in-hospital functional status may help facilitate this process, this area remains under-researched to date. Factors associated with functional decline in the hospitalized elderly include the types of morbidities and the reasons for their admission. Indeed, elderly with chronic kidney disease (CKD) are more likely to exhibit functional decline, beginning from the earlier stage of CKD to end-stage renal disease (ESRD)4,5; functional dependency also predisposes individuals with CKD and ESRD to recurrent hospitalization and higher mortality.

Albuminuria and proteinuria, as the staging criteria for CKD in the most recent version of Kidney Disease Improving Global Outcomes (KDIGO) CKD guidelines, are both well-established predictors of subsequent renal function decline. There is increasing awareness that albuminuria and proteinuria have an independent role in the prediction of adverse outcomes apart from the baseline renal function. As explained above, although CKD is associated with poor functional status, it is still unclear whether proteinuria alone exhibits similar association with functional status regardless of CKD. No reports focus on this association using the severity of proteinuria among geriatric patients with acute medical illnesses.

What is the difference between DNA and RNA

Posted by in categories: biotech/medical, genetics

To understand 1st how to solve things like cancer, or other immune deficiency disorders, or to solve the human system’s other mysteries; one must understand DNA v. RNA.


DNA is a deoxyribonucleic acid and is a hereditary material in all living organism. It is located in the nucleus of cell which is known as nuclear DNA. But small amount of DNA is also found in the mitochondria known as mtDNA or mitochondrial DNA whereas RNA is ribonucleic acid present in all living cells. It carries instructions from DNA which controls the synthesis of proteins but in some viruses RNA, instead of DNA carries the genetic information. Do you know who had reported first time nucleic acids in 1871 — Friedrich Miescher from nuclei of pus cells.

Researchers Explain Mechanism Controlling Cell Protein Generation

Posted by in categories: biotech/medical, genetics

Yesterday, I shared the new cancer research discovery by Prof. Samie Jaffrey and his team. The following provides additional details on their discovery.


The human body is made of trillions of cells. Each fulfills a specific purpose, undergoes tremendous wear and tear and is eventually replaced. Despite extensive research, some questions related to protein production that fuels this simple process have gone unanswered. Fascinated by these intricacies, Prof. Samie Jaffrey, pharmacology, may have found part of the answer.

Jaffrey and his team discovered that messenger RNA molecules, responsible for conveying genetic information to protein producers in the cell, have special features that predetermine how much protein they generate. The discovery could provide scientists with a greater understanding of the causes of cancer and ways of regulating it.

Genetics Is Giving Way to a New Science of Life

Posted by in categories: biotech/medical, education, genetics, science

By Jonathan Latham, PhD

Test your understanding of the living world with this simple question. What kind of biomolecule is found in all living organisms? If your answer is “DNA”, you are incorrect. The mistake is very forgiveable though. The standard English-language biology education casts DNA (DeoxyriboNucleic Acid) as the master molecule of life, coordinating and controlling most, if not all, living functions. This master molecule concept is popular. It is plausible. It is taught in every university and high school. But it is wrong. DNA is no master controller, nor is it even at the centre of biology. Instead, science overwhelmingly shows that life is self-organised and thus the pieces are in place for biology to undergo the ultimate paradigm shift.

Removing the Viral Threat: Two Months to Stop Pandemic X from Taking Hold

Posted by in categories: biotech/medical, genetics, health

Over the past several years, DARPA-funded researchers have pioneered RNA vaccine technology, a medical countermeasure against infectious diseases that uses coded genetic constructs to stimulate production of viral proteins in the body, which in turn can trigger a protective antibody response. As a follow-on effort, DARPA funded research into genetic constructs that can directly stimulate production of antibodies in the body., DARPA is now launching the Pandemic Prevention Platform (P3) program, aimed at developing that foundational work into an entire system capable of halting the spread of any viral disease outbreak before it can escalate to pandemic status. Such a capability would offer a stark contrast to the state of the art for developing and deploying traditional vaccines—a process that does not deliver treatments to patients until months, years, or even decades after a viral threat emerges.

“DARPA’s goal is to create a technology platform that can place a protective treatment into health providers’ hands within 60 days of a pathogen being identified, and have that treatment induce protection in patients within three days of administration. We need to be able to move at this speed considering how quickly outbreaks can get out of control,” said Matt Hepburn, the P3 Program Manager. “The technology needs to work on any viral disease, whether it’s one humans have faced before or not.”

Recent outbreaks of viral infectious diseases such as Zika, H1N1 influenza, and Ebola have cast into sharp relief the inability of the global health system to rapidly contain the spread of a disease using existing tools and procedures. State-of-the-art medical countermeasures typically take many months or even years to develop, produce, distribute, and administer. These solutions often arrive too late—if at all—and in quantities too small to respond to emerging threats. In contrast, the envisioned P3 platform would cut response time to weeks and stay within the window of relevance for containing an outbreak.

First stable semisynthetic organism created

Posted by in categories: biotech/medical, genetics

DNA — now with a new base pair! (credit: Romesberg Lab)

Scientists at The Scripps Research Institute (TSRI) have developed the first stable semisynthetic organism — a bacterium with two new synthetic bases (called X and Y) added to the four natural bases (A, T, C, and G) that every living organism possesses. Adding two more letters to expand the genetic alphabet can be used to make novel proteins for new therapeutics, according to the researchers.

All life as we currently know it contains just four bases that pair up to form two “base pairs” — the rungs of the DNA ladder — which are simply rearranged to create different organisms.

Synbio and Biosecurity

Posted by in categories: bioengineering, genetics, quantum physics

Wait until you see how Quantum bio is applied in Biosecurity.


By guest author Devang Mehta

The world in 1918 was emerging from under the pall of a World War that had claimed 38 million lives, and yet in the span of only one year, just as many lives would be lost to the Spanish Flu an influenza pandemic that is still regarded the single deadliest epidemic in recorded history. The disease reached all corners of the world, from the Antipodes to Europe and Asia, eventually claiming 20–50 million lives. The 1918 virus caused unusually strong symptoms, described by one physician at the time as “a blood-tinged froth that sometimes gushed from (the) nose and mouth”. The disease also had an incredibly high mortality rate of 10–20%, which combined with a high rate of infection meant that up to 6% of the world’s population died due to the virus.
