DOI: 10.1038/s41551-017-0137-2AbstractClustered regularly interspaced short palindromic repeats (CRISPR)–CRISPR associated protein 9 (Cas9)-based therapeutics, especially those that can correct gene mutations via homology-directed repair, have the potential to revolutionize the treatment of genetic diseases. However, it is challenging to develop homology-directed repair-based therapeutics because they require the simultaneous in vivo delivery of Cas9 protein, guide RNA and donor DNA. Here, we demonstrate that a delivery vehicle composed of gold nanoparticles conjugated to DNA and complexed with cationic endosomal disruptive polymers can deliver Cas9 ribonucleoprotein and donor DNA into a wide variety of cell types and efficiently correct the DNA mutation that causes Duchenne muscular dystrophy in mice via local injection, with minimal off-target DNA damage. Gene-editing alternative corrects Duchenne muscular dystrophy CRISPR-associated protein Cas9 (white) from Staphylococcus aureus based on Protein Database ID 5AXW. Credit: Thomas Splettstoesser (Wikipedia, CC BY-SA 4.0) CRISPR-Cas9 has been in the news a lot lately because it allows researchers to directly edit genes—either disabling unwanted parts or replacing them altogether. But despite many success stories, the technique still suffers from a major deficit that prevents it from being used as a true medical tool—it sometimes makes mistakes. Those mistakes can cause small or big problems for a host depending on what goes wrong. Prior research has suggested that the majority of mistakes are due to delivery problems, which means that a replacement for the virus part of the technique is required. In this new effort, the researchers report that they have discovered just a such a replacement, and it worked so well that it was able to repair a gene mutation in a Duchenne muscular dystrophy mouse model. The team has named the new technique CRISPR-Gold, because a gold nanoparticle was used to deliver the gene editing molecules instead of a virus.The new package was created by modifying a bit of DNA to cause it to stick to a gold nanoparticle and then a Cas9 protein and also an RNA guide. The package was then coated with a polymer that served as a containment casing—one that also triggered endocytosis (a form of cell transport) and helped the molecules escape endosomes once inside the target cells. The molecules then set to work—the Cas9 cut the target DNA strand, the guide RNA showed what needed to be done and a DNA strand was placed where a mutation had existed. The result was a gene free of a mutation that causes Duchenne muscular dystrophy.There is still a major problem to overcome with the technique, however—it only works in localized applications. Ideally, a mass of packages would be injected into the bloodstream allowing for repair of all cell types, such as muscles impaired by a mutant gene. Explore further (Phys.org)—A team of researchers from the University of California and the University of Tokyo has found a way to use the CRISPR gene editing technique that does not rely on a virus for delivery. In their paper published in the journal Nature Biomedical Engineering, the group describes the new technique, how well it works and improvements that need to be made to make it a viable gene editing tool.

Kolkata: Chief Minister Mamata Banerjee launched a scathing attack on the BJP for its “malicious attempts to malign” the name of Missionaries of Charity.This comes after names of two members of Ranchi unit of the Missionaries of Charity have been “dragged” into the controversy involving the sale of babies. As the investigation heats up, Banerjee stepped in to stick up for the Mother Teresa-founded NGO.On Thursday, the Chief Minister, who is at present in North Bengal, tweeted: “Mother Teresa herself set up Missionaries of Charity. And now they are also not being spared. Malicious attempts to malign their name.” Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedRaising her voice against the action, Banerjee further stated in her tweet: “The Sisters are being targeted. #BJP want to spare no one.”She condemned the move and maintained: “Highly condemnable. Let MOC continue to do their work for the poorest of the poor.”The Chief Minister has always raised her voice against “anti-people” moves of the BJP government and over and again, slammed it for its “communal” and at the same time “vendetta” politics.It was on May 22 that Banerjee extended her support for the Archbishop of Delhi, Anil Couto after he wrote a letter stating that “we are witnessing a turbulent political atmosphere which poses a threat to the democratic principles enshrined in our Constitution and the secular fabric of our nation.” Also Read – Naihati: 10 councillors return to TMC from BJPIn this connection, Banerjee had stated: “We have great regard and respect for all communities, caste and creed.

With the increasing crime rate, Indian parents are looking for a sport for their children that would teach them the art of self-fefence and protection.Korean Cultural Centre India, in view of the same, has organised two months free Taekwondo classes, which will go until October 31.The students will be trained by Master Wan Yong Lee – who will be focusing on teaching self-defense techniques, fights, taekwondo, poomsae, taekwondo demonstration, and dance, teaching etiquettes and manners to the participants. Master Lee has been training Indian students from the age group of six years to 24 years at KCC, which also includes Indian Athletes who participated in this year’s Asian Games.”Unlike the common prejudice about the sport, it is more than a fighting game. Its ultimate goal is to develop and cultivate the personality of the player through physical, mental and spiritual discipline,” he says.Taekwondo – a form of Korean martial art is South Korea’s national sport.It became an official Olympic sport in 2000, and since then it has been disseminated in 203 countries.
Designer Anita Dongre, who has moved one step closer to her dream of empowering the women of India by opening the fourth tailoring unit in the village of Modgaon in Maharashtra, says there has been a sense of urgency within the industry to save the country’s dying crafts. She feels there is a better understanding of Indian textiles and slow fashion on a global level today.”There has been a sense of urgency within the industry to save India’s dying crafts. It’s great to see not just the industry but also the government taking steps towards reviving handloom and making it relevant to the current generation,” said Dongre when asked about her take on how the scene of handloom has changed over the years.

It’s amazing to see the progress we are making towards this as an industry. Social media also has been a huge enabler for us to tell our stories of Indian handlooms and textiles. Also Read – Over 2 hours screen time daily will make your kids impulsiveTalking about the new tailoring unit, the designer said Anita Dongre Foundation works with the local governments and village gram panchayats to create local Women Self Help Groups (SHGs) and bring livelihood or employment opportunities to their own villages. “Empowering the people of these villages by giving them access to a dependable source of income, in their locality is critical to arrest the tide of migration to cities. Modgaon is the fourth location where we have setup a community garment tailoring unit (in addition to Charoti, Jawahar and Dhanevari) in the Palghar District of Maharashtra. “There are no skilled artisans or weavers in these villages – the women from these villages are unskilled labour who we skill in garment tailoring on industrial sewing machines by setting up such training-cum-production centres, and this has been our key objective,” she said.Added Dongre: “During the three months of training period, we train the women in basic and advanced skills of cutting, sewing and finishing garments and during this period every trainee is paid a stipend.””Once the training is complete, we supply the center with fabrics and pay the women for the tailored garments on fair per piece rate basis so as to provide them with regular livelihood opportunities.”
