The nanoparticles were used as a unique sustained release drug delivery mechanism. They are composed of a hybrid hydrogel/glass capsule containing nitric oxide. The nitric oxide (NO) is slowly released at therapeutic levels when applied to the cutaneous. NO aids in erection biology and helps to relax smooth muscle cells; it occurs naturally in the body to help expand blood vessels, helping them fill with blood. The nanoparticles were applied topically to the skin of the penis of seven rats and the erectile response was measured by intracorporal pressure/blood pressure ratio. 71% of the rats tested with the nanoparticles experienced positive effects on the ICP/BC which led to visible erections, with an average response time of 65 minutes. The researchers claim that this topical treatment will likely have fewer side effects than Viagra, which is ingested orally, and known to cause headaches and facial flushing. They also claim that given further research, their nanoparticle treatment could work faster than Viagra. Says Ira D. Sharlip, MD, “This is a very interesting concept which has potential to impact treatment of many conditions including erectile dysfunction if it can be translated from the animal lab to clinical practice. It remains to be seen whether the effect of the nanoparticle technology is a local or a systemic effect.” The nanoparticles could act as a transport mechanism for erectogenic agents, and could help localize the therapeutic impact without the potential systemic consequences of an ingested pill. Dr. Sharlip also feels that this type of technology can be applied to other problems such as premature ejaculation, which occurs in 20-30% of men. With further research, I’m sure that a solution for this problem will come soon. Hopefully, this research will translate well to clinical practice, and will give further validation to programs seeking to use nanotechnology for medical/health applications. For example, companies such as Tego Biosciences are hoping to use fullerenes as therapeutics, and there is numerous research into using carbon nanotubes as a cancer killer. Needless to say, given the age distribution amongst those at NIH, I’m sure this particular research will continue to be well funded.© 2009 PhysOrg.com This document is subject to copyright.

Viagra sales don’t meet expectations (PhysOrg.com) — A new generation of anti-impotency drugs based on nanoparticles might be coming quickly. Researchers at the Albert Einstein College of Medicine in New York presenting at the 104’th Annual Meeting of the American Urological Association have discovered a new potential application for drug carrying nanoparticles as a topical treatment for erectile dysfunction (ED). This breakthrough should hopefully stimulate further work in this area.

This inhaler, which has been developed for Asthmapolis and dubbed Spiroscout, takes readings every time that it is puffed by a user. Those readings include both a time of use, and the location in which it was used. That data is then sent to a central computer for analysis.This has two major benefits for asthma sufferers. The first is that is allows a patient, with the assistance of a physician to analyze their inhaler use. This process can reveal patterns in inhaler use and indicate adjustments that are needed in the patients medication schedule. The second benefit is in the accumulated data that will be collected. The information obtained through this program could provide valuable insights for epidemiologists, who will be able to study data from an entire group of asthma sufferers, without relying on self-recorded logs. The data may also lead to a better understanding of air quality in an area.Dr. Van Sickle’s device is not the first GPS enabled inhaler on the market. In 2009 SiliconSky GPS developed the first iteration of the technology for Asthmapolis, but that device had a chunky box attached to the back. Dr. Van Sickle’s device has the GPS built into the cap, making the device slimmer and easy to carry. (PhysOrg.com) — Asthma is a serious medical condition that can have life threatening consequences. That is why most asthmatics carry an inhaler. It is small enough to be nestled in a purse, or carried in a pocket, and most asthmatics will not leave home without it. That is why it is a perfect tool for collecting epidemiological data about asthma.
The Process of self quest is not all simplistic. To know or not, what to know what not, how to know, all the following queries are life consuming; abstract yet subjective, like a mirage. And man’s eternal search to discover the self has never perished. It has attained distinct hues over the years because the search is not an outward but an inward experience.It is this very spirit of searching new alleys of self discovery that is explicitly visible in the show Avidya meaning ‘the true spirit of searching self’. The exhibition will be organised by S2SArtivities, an organisation working towards promoting Indian art. Also Read – ‘Playing Jojo was emotionally exhausting’The exhibition showcases works of twelve young Indian artistes from distinct parts of the country and two artistes from Taiwan and UK. Artists like Debasis Barui, Deepak Rajbhar, GirishKulkarni, M S Baoni, Narasimha M Kumbar, NidhiAgarwal, Nilanjana Nandy, Prasanta Kalita, Sajal Kaity, Sumantra Mukherjee, Tisha Mandal and Vinita Dasgupta will be displaying their work.The exhibition will also showcase works of two distinguished artists Glenn Fitzpatrick from UK and I Hui Kuo from Taiwan.Though the show incorporates paintings of distinct genres and style, it together forms a composite whole. This diversity in a continuum, enhances the intensity of the works displayed. The beautiful blending of diverse national and international traits and understanding makes Avidya something to watch out for.
On the occasion of World Photography Day, leading child rights NGO, CRY- Child Rights and You organised a photography workshop for underprivileged children. The workshop was a part of CRY’s Click Rights campaign which is a national citizen photojournalism campaign aimed at pictorially highlighting the barriers to education still faced by 8,150,618 children in India. With the advent of the national general elections early next year, CRY seeks to motivate citizens – especially first-time voters – to demand accountability from duty bearers on the promises made to children. Also Read – ‘Playing Jojo was emotionally exhausting’CRY will share the pictures collected as evidence in its advocacy efforts at the local and national level.Children from all CRY projects in Delhi were invited to be a part of this unique workshop. The core idea behind this workshop was to let them capture the thoughts and situations that these children face in their day to day life. Children clicked their barriers and showcased them in the form of pictures.Select pictures clicked by the children in the photography workshop will be showcased at an exhibition from 25 August at 1 AQ, New Delhi. The workshop was coordinated by Vicky Roy who is a real-life example of courage and resilience. He ran away from home as child and became a rag picker to earn pocket money. He found refuge at a NGO for street children where he met a photographer that changed his life. Despite his turbulent past, Vicky pursed his passion for photography in which he was selected to photo document the reconstruction of the World Trade Center in NYC.

India’s Daughter, an India-uk co-production, Directed and produced by british oscar award winning Leslee Udwin (for the film East is East) and co-produced by Dibang. The film will be shown on March 8th International Women’s Day on National television in India and also simultaneously in UK, Denmark, Sweden, Switzerland, Norway and Canada. India’s Daughter tells the story of the horrific Delhi gang rape of Nirbhaya which sent shockwaves around the world in December, 2012, and of the unprecedented protests and riots which this horrific event ignited throughout India, demanding changes in attitudes towards women. Also Read – ‘Playing Jojo was emotionally exhausting’Director-Producer Leslee Udwin describes what impelled her to make the documentary: “When news of this gang-rape hit our TV screens in December 2012, I was as shocked and upset as we all are when faced with such brazen abandon of the norms of ‘civilised’ society. But what actually inspired me to commit to the harrowing and difficult journey of making this film was the optimism occasioned by the reports that followed the rape. Courageous and impassioned ordinary men and women of India braved the December freeze to protest in unprecedented numbers, withstanding an onslaught of teargas shells, lathi charges and water canons, to make their cry of ‘enough is enough’ heard. In this regard, India led the world by example – and I love India for this. In my lifetime, I can’t recall any other country standing up with such commitment and determination for women’s rights.” Also Read – Leslie doing new comedy special with NetflixWith exclusive and unprecedented access, the film examines the values and mindsets of the rapists, Mukesh Singh’s interview offers a revealing insight into his attitudes towards women and into why men rape.In his interview, he says women are more responsible for rape than men, women should not travel late at night, nor should they go to discos and bars or wear the ‘wrong clothes’. He also claims that his execution will make life more dangerous for future rape victims. Mukesh Singh suggested the rape and beatings were to teach Jyoti and her friend a lesson that they should not have been out late at night. And he criticised Jyoti for having fought back against her attackers saying: “When being raped, she shouldn’t fight back. She should just be silent and allow the rape. Then they’d have dropped her off after ‘doing her’, and only hit the boy.” Of her encounter with the rapists (during 31 hours of interviews in Tihar Jail, over 7 days), Udwin says: “The horrifying details of the rape had led me to expect monsters. The shock for me was discovering that the truth couldn’t be further from this. These were ordinary, apparently normal and certainly unremarkable men who shared a rigid and ‘learnt’ set of attitudes towards women. What I learned from these encounters, is the degree to which society itself is responsible for these men and for their actions. These rapists are not the disease, they are the symptoms. Gender inequality is the disease, and gender inequality is the solution, the only one.”Another defence lawyer who acted in the case, ML Sharma, says: “You are talking about man and woman as friends. Sorry, that doesn’t have any place in our society. We have the best culture. In our culture, there is no place for a woman.”Jyoti’s mother sums up a widely held attitude: “Whenever there’s a crime, the girl is blamed, ‘She should not go out. She shouldn’t roam around so late or wear such clothes.It’s the boys who should be accused and asked why they do this. They shouldn’t do this.”Writer and historian Dr Maria Misra of Oxford University says: “Her death has made a huge difference. I think that, first of all, it has really brought home the issue of the problems of the way young and independent women are perceived in Indian society. It’s opened up a debate in India that I think hasn’t been held publicly and widely about exactly what the relationship between men and women should be.”
Kolkata: In a rare gesture of humanity, family members of an accident victim donated the body so that the organs can be used to give a new lease of life to someone else.A 26-year-old youth, Trijit Ghosh, was killed after being hit by a private bus on Upen Banerjee Road at Parnasree in South Kolkata on Tuesday morning. He was riding a motorbike and the bus hit from behind after losing control. He received severe injuries all over his body.The accident took place near a local club. Youth from the club and police took him to Vidyasagar State General Hospital where he was declared brought dead. The body has been sent for an autopsy. The offending vehicles were seized. A pall of gloom descended when the news of Trijit’s death reached his residence at Kalighat. But his family members took the decision to donate the body so that the organs can be used to give a new lease of life to someone else.Doctors have examined the body and confirmed that his eyes and skin can be used. Hence, accordingly the process has started so that the eyes can be used by someone else.According to senior police officers, the family members of the victim have set an example by attempting to give vision to a person by donating the eyes of the deceased youth.
Kalyani: In a significant stride towards ensuring that people can buy LPG cylinders according to their financial capacity, Indian Oil Corporation Limited (IOCL) has introduced cylinders with 5 kg refilling capacity.”There is a section of people, who face difficulty in doling out an amount of Rs 780 at one go for cylinders with 14 kg capacity. Hence, we have introduced 5 kg refill cylinders. Customers can now opt for either 14 kg or 5 kg LPG cylinders,” said Abhijit Dey, General Manager (LPG) IOCL. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe 5 kg refill will cost around Rs 300, a senior IOCL official added.The IOCL will soon introduce LPG gas supply at its two plants in Durgapur and Kalyani via pipeline to ensure uninterrupted supply. We have our two refineries at Paradip and Haldia. The gas pipeline will connect Paradip-Haldia with Durgapur and Kalyani. The link with Durgapur will be achieved in three months time, while Kalyani will be completed by theend of this year.It will not only bring down transportation cost via road but most importantly will usher in an uninterrupted supply,” Dey maintained.Presently, the bottling plants receive cylinders in bulk by tankers and then refilling is done at the plants before being despatched to customers. “In the next phase, the Budge Budge bottling plant will be linked through pipeline,” said RS Bhattacharya, deputy general manager, marketing (eastern region), IOCL.
