Scientists at Children’s Hospital Los Angeles Develop Breakthrough In Vitro Model

Posted by fidest press agency su venerdì, 16 agosto 2019

Kidneys work to constantly filter blood and remove toxins from the body. Conditions such as chronic kidney disease (CKD) are characterized by a reduced ability to perform this essential function. CKD incidence is growing and more than 1.4 million individuals depend on dialysis or kidney transplant for survival. Development of new treatments requires an understanding of the mechanisms of the disease progression, but scientists have not been able to accurately model kidney filtration in vitro – until now.
In a landmark study published in Nature Communications, scientists at Children’s Hospital Los Angeles demonstrate an in vitro kidney model that could change the course of research for diseases like CKD.The kidney contains specialized structures called glomeruli. Within each glomerulus is a filtration barrier made up of two thin layers of highly specialized cells and a membrane that acts as a selective filter. As blood moves through each glomerulus, toxins and small molecules can pass through, while proteins and other important components are kept in the bloodstream. “This filtration process breaks down in patients with kidney disorders,” explains Laura Perin, PhD, who is co-senior author on the study along with Stefano Da Sacco, PhD. “But because we haven’t had a good in vitro model, we still don’t know the mechanisms of injury to the glomerulus in CKD.” Dr. Perin and Dr. Da Sacco conduct research in the GOFARR Laboratory for Organ Regenerative Research and Cell Therapeutics in Urology along with co-director Roger De Filippo, MD, at CHLA’s Saban Research Institute. The lead author on the study was CHLA postdoctoral research fellow Astgik Petrosyan. Together, the team studies the structure of the glomerulus to better understand how and why their ability to filter blood breaks down.

Have we found all the elements?

Posted by fidest press agency su sabato, 22 ottobre 2016

watch-the-videoFour elements have been added to the periodic table this year, completing the seventh row. However, these new elements are not naturally occurring. Scientists had to create them and overcome a number of challenges to do so. In this week’s Reactions video, we look at how elements are made and whether or not creating even more is possible. The American Chemical Society is a nonprofit organization chartered by the U.S. Congress. With nearly 157,000 members, ACS is the world’s largest scientific society and a global leader in providing access to chemistry-related research through its multiple databases, peer-reviewed journals and scientific conferences.

New database gives scientists hope for helping coral reefs

Posted by fidest press agency su venerdì, 22 aprile 2016

With the future of coral reefs threatened now more than ever, researchers have announced the release of a new global database that enables scientists and managers to more quickly and effectively help corals survive their many challenges.In a paper describing the database, published recently in Scientific Data, Professors Andrew Baird and Sean Connolly from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) say the Coral Trait Database will assist scientists working on coral reefs answer a multitude of questions.“The trait database is the first of its kind for corals and will allow coral reef scientists to begin to address many significant, unresolved questions – and much faster,” Professor Baird says.“Traits are fundamental to most aspects of the ecology and evolution of coral1organisms,” he explains. “For example, the Great Barrier Reef is now in the grip of perhaps the largest coral bleaching episode in history, and this database can help scientists explain why some species are more susceptible than others.”Associate Professor Joshua Madin from Macquarie University’s Genes to Geoscience Research Centre, who led the team developing the database, adds, “In fact, there are hardly any questions you can’t ask of the database: its number of uses are extraordinary, but progress in these areas has been hindered by the lack of readily accessible trait data.”
Baird, Madin and their colleagues spent thousands of hours compiling the database over the past few years. They sifted through papers published in journals, tables printed in books, and examined other resources scattered around the globe.
Some of the data had been buried in obscure, often difficult to access – but highly informative – books dating back to the 1800s. The Coral Trait Database promises to save a lot of time, money and effort across all fields of coral reef studies.“A lot of these data were not easily accessible, and it was expensive for many to get to,” explains Professor Sean Connolly. “So much of the Coral Trait Database content was previously only available to the “elite”. The existence of this tool also means the coral reef research community can cut down on redundant research efforts.”Coral reefs remain one of the most diverse and valuable ecosystems on the planet, hosting more species than any other marine environment. Globally, an estimated 275 million people rely directly on coral reefs for food, protection from waves and storms, income, and cultural value. They are also crucial in providing protection and habitat for healthy fish populations. However, in the past 20 years, coral cover has diminished by as much as 95 percent in some locations.Climate change and the El Niño of the recent months combined are currently contributing to a global mass-bleaching event – and on a scale previously unseen in recorded history. Added stresses from pollution and over-fishing further complicate coral reef health.“Coral reefs are changing rapidly, and that is unlikely to slow down,” Madin says. “If we don’t understand these changes, we can’t protect these species-rich ecosystems. We need to speed the science up, and to think creatively about how to do that.”“We hope this database will support scientists trying to make a difference by providing them access to the data they need quickly, and at no cost.”
The Coral Trait Database houses physiological, morphological, ecological, phylogenetic and biogeographic trait information at: https://coraltraits.org with the vision of being an inclusive and accessible data resource to more rapidly advance the science and management of a sensitive ecosystem at a time of unprecedented environmental change. The database is open and accessible to the public.

Women scientists gaining ground: High proportion of female participants at the Lindau Nobel Laureate Meeting

Posted by fidest press agency su giovedì, 26 marzo 2015

unescoAn exceptionally high number of young female scientists will be taking part in the 65th Lindau Nobel Laureate Meeting with the proportion of women amongst the 672 young scientists standing at 42%. According to data from UNESCO, only 30% of all researchers worldwide are female. The percentage of women amongst the Nobel Laureates is significantly lower still – 814 men, but just 46 women have received the award since 1901. This ratio is also reflected at the Lindau Meeting. A record number of 70 laureates are attending but just three are female. This year’s Lindau Nobel Laureate Meeting is interdisciplinary and will take place from 28 June to 3 July in Lindau on Lake Constance. The list of participants has now been announced.“The Lindau Nobel Laureate Meetings are future-oriented. This is indicated not least by the large number of young female scientists taking part. Their presence also sends out a strong message to their home countries to attract and retain more talented women in science,” remarked Helga Nowotny, co-founder and President of the European Research Council (ERC) from 2010 to 2013 and Vice-President of the Council for the Lindau Nobel Laureate Meetings.Burkhard Fricke, also a member of the Council, emphasised that no female quota was used in the selection of the young scientists: “The young participants were evaluated purely on the basis of specialist criteria. The quality of the applications has once again risen significantly which made selecting the best of the many candidates extremely challenging.” Students, doctoral students and postdocs from a total of 88 countries were accepted. They are conducting research in the Nobel Prize disciplines of medicine, physics or chemistry.The three female Nobel Laureates who will be coming to Lindau this year are the Frenchwoman Françoise Barré-Sinoussi (Nobel Prize in Medicine in 2008), the Australian Elizabeth Blackburn (Nobel Prize in Medicine in 2009) and Ada Yonath from Israel who became only the fourth woman in the history of the Nobel Prize to be awarded the Nobel Prize in Chemistry in 2009.During a panel on “Women in Science” at the 2014 Lindau Nobel Laureate Meeting, Elizabeth Blackburn remarked that there was now a pleasingly high proportion of women amongst science students but this was not replicated in lecturing and cutting-edge research. She called upon academic institutions to redouble their efforts to increase opportunities for women in these areas.

Posted by fidest press agency su venerdì, 14 novembre 2014

Françoise M. WinnikWASHINGTON, The American Chemical Society (ACS) announces that Françoise M. Winnik, Ph.D., will assume the role of editor-in-chief of the journal Langmuir. Winnik currently serves as a professor at the University of Montreal in the faculty of pharmacy and department of chemistry.Françoise M. Winnik, Ph.D. will succeed Editor-in-Chief David G. Whitten, Ph.D., who has served in this position since 1997 and will retire from the journal at the end of 2014. An interdisciplinary publication, Langmuir records progress in several areas, including colloids, interfaces and material science.Excited about taking the reins of such a well-respected journal, Winnik says she is “looking forward to making sure that Langmuir remains a high-quality, must-read journal for many years to come, and that it meets the needs and expectations of our readers, authors and reviewers.””Langmuir is the go-to journal for scientists working at the nexus of several fields related to materials science, nanoscience and nanotechnology,” Winnik continues. “The journal focuses on all aspects of interface and colloid science. And while this may seem limited in scope, it’s not. Interfaces and colloids are so diversified and ubiquitous around us! I have always been enthusiastic about Langmuir because of this breadth of topics among articles in every issue.”Winnik got her start in France, earning her undergraduate degree in chemical engineering in 1973 at the Ecole Nationale Supérieure de Chimie de Mulhouse. For her master’s and Ph.D. degrees, she went on to the University of Toronto, where she also conducted postdoctoral research. In 1981, she took a position as a research scientist at the Xerox Research Centre of Canada. After 12 years in the private sector, she became an associate professor in the departments of chemistry and physics at McMaster University in Canada. In 2000, she joined the ranks of her current institution, the University of Montreal. Winnik also is a principal investigator at the WPI International Center for Materials Nanoarchitectonics of the National Institute for Materials Science in Tsukuba, Japan, and a Finnish distinguished professor at the University of Helsinki in Finland.The interdisciplinary research group she leads combines fundamental physical chemistry, polymer science and surface chemistry to applied fields, such as nanomedicine and nanotoxicity.”I am honored to welcome Dr. Winnik as editor-in-chief of Langmuir, and have no doubt that her enthusiasm, knowledge of the field, editorial experience and standing in the community will allow her to lead Langmuir to new heights over the coming years,” says Susan King, Ph.D., senior vice president of ACS Publications.Langmuir retains the preeminent position in colloid and interface science that it has established since its inception in 1985. It leads the field in terms of articles published (1,889 in 2013), citations captured (133,157 in 2013) and Impact Factor (4.384 in 2013). Despite its size, Langmuir also offers some of the fastest article processing times from submission to publication in the field.The American Chemical Society is a nonprofit organization chartered by the U.S. Congress. With more than 161,000 members, ACS is the world’s largest scientific society and a global leader in providing access to chemistry-related research through its multiple databases, peer-reviewed journals and scientific conferences.

Churches, scientists, and politicians discuss human enhancement

Posted by fidest press agency su lunedì, 23 aprile 2012

The building of the European Parliament in Brussels, Espace Léopold (Photo credit: Wikipedia)

From 25-27 April 2012, around 50 representatives mainly from European churches but also from other religions and the fields of politics, ethics, and science, will meet in Brussels to discuss the pros and cons of human enhancement. The conference is organized by the Church and Society Commission (CSC) of the Conference of European Churches (CEC), a platform in which a range of Christian denominations in Europe work together. A visit to the European Parliament, including a discussion with representatives of different political parties, is included.Through the use of nanotechnology, genetic screening and engineering, implanted computer devices, and other techniques, human beings can now live longer, more comfortably, and can perform better. Part of the expectations on this so called “human enhancement” may be too pretentious, but even so, human enhancement does exist and develops rapidly. Should we be happy about these techniques? Will they contribute to better relationships, happier people, and more humane societies? Do they lead to a blurred distinction between humans and machines – and if so, is this good or bad? What about the financial costs? And will human enhancement lead to a new anthropology and a changed view on God and religion? Does it challenge traditional religious views?
The aim of the conference is to listen, discuss, and to explore possible points of moral agreement and concern. The aim is not to formulate final normative statements. Participants from 18 countries will take home both up to date factual information and normative insights. Within the context of the CEC, a task force of church representatives will continue to discuss questions of biotechnology in the year to come and help member churches and other stakeholders to form their own opinions. Directly after the conference, on Friday at 14.00, a bulletin will be issued containing conclusions and recommendations.
