Prozac slows development

first_imgBy Cat HolmesUniversity of GeorgiaResearchers at the University of Georgia have found that low-level exposure to a common class of antidepressants found in streams and ponds delays both development in fish and metamorphosis in frogs.The scientists are studying toxicity of a widely used group of antidepressants called selective serotonin reuptake inhibitors (SSRIs).The study has important environmental implications because some of these widely-prescribed drugs, which include Prozac, Zoloft, Paxil and Celexa, have been found in low concentrations in surface water, particularly wastewater.“While these compounds are not acutely toxic at concentrations detected in the environment, our longer term studies indicate delayed development (in fish) and delayed metamorphosis (in frogs),” said UGA aquatic toxicologist Marsha Black who led the study.FishThe researchers found that low concentrations of fluoxetine (Prozac), the most commonly prescribed SSRI, significantly slowed development in Gambusia, or mosquitofish, which are often used to study toxicity on aquatic organisms. “We found that male sexual development slowed by two to four weeks,” said Ted Henry, a UGA researcher who also worked on the project.When the fish were around 80-85 days old, he said, the sexual maturity of those exposed to low levels of fluoxetine was significantly delayed. However, by the end of the study, when the fish were 145 days old, the same fish had caught up developmentally with the unexposed fish.“We’re scratching our heads right now as to exactly what this means,” Black said. “But we know that in water, timing is everything. Reproduction for some species is timed to coincide with algae blooms for example. And possibly if sexual development is delayed, timing of reproduction could be affected and you could see some population impact.”For the next phase of the study, the researchers will more closely examine the reproductive tissue of the fish affected by fluoxetine. Are they able to reproduce? Is there a reduction in the number of embryos? Or is there no ultimate effect? “These are some of the questions we’d like to answer,” Black said. “There are still a lot of unanswered questions.”FrogsThe researchers also found that metamorphosis in frogs exposed to low levels of fluoxetine took longer than usual. For frogs, particularly the land-based frogs of North America, such a delay could be a matter of life and death, Black said, because frog eggs are often laid in temporary water beds – ephemeral ponds and wetlands that dry up.“If the tadpoles have not developed and undergone metamorphosis by the time the water has evaporated, they’ll dessicate with the ponds,” Black said.The researchers strongly suspect that results implicate a disruption of thyroid function and will carry out further research this spring to confirm or deny their suspicions.“We know that the thyroid levels peak with metamorphic climax, when the legs and arms form and the tail resorbs” Black said. “We believe that fluoxetine inhibits the thyroid so we’re measuring the thyroid hormone levels next.” SSRIs in the environmentThe number of prescriptions for SSRIs has exploded since Prozac first came on the market 15 years ago. SSRIs are most often prescribed for depression, but are also used to treat anxiety, panic disorder, obsessive compulsive disorder, eating disorders, and social phobia. Because they are prescribed for chronic conditions, people take them for months or years, increasing the likelihood of build-up in surface water, Black said. A recent study by Baylor toxicologist Bryan Brooks found traces of fluoxetine in the tissue of bluegills in a Texas creek fed by discharges from a wastewater treatment plant. “Treated municipal drinking water should be fine, but [pharmaceuticals like SSRIs] may not be filtered out of wastewater,” Black said. “We should be putting a high priority on implementing technologies that remove them and other pharmaceuticals from municipal wastewater discharges.”The findings of the UGA study will be presented at the 24th Annual Meeting of the Society of Environmental Toxicity and Chemistry next month.(Cat Holmes is a news editor for the University of Georgia College of Agricultural and Environmental Sciences.)last_img read more


How to deal with a personality conflict at work

first_img 19SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr,John Pettit John Pettit is the Managing Editor for CUInsight.com. John manages the content on the site, including current news, editorial, press releases, jobs and events. He keeps the credit union … Web: www.cuinsight.com Details In your lifetime, you’re going to work with someone who you won’t get along with. Often, it’s a personality conflict. Usually when two personalities clash, both parties are partially to blame. If you find yourself in this situation, here are a few tips for getting past the conflict and moving forward.Keep it on the down-low: Obviously when there’s some conflict, you need to find a resolution. The best thing you can do in the process, is to not let it cause division among your fellow employees. When lines are drawn, and allies and enemies are made, it’ll make it ten times harder to resolve the situation. Don’t make it tougher than it has to be.Take five: A back in forth argument usually won’t get you anywhere. You’ll get emotional and will ignore logic and reason. Take a minute to get your thoughts organized and turn those reactions into responses. A clear head always helps when trying to resolve a conflict.Two rights make an argument: You’ve probably heard that “there’s more than one way to skin a cat.” While this phrase is weird and puzzling to small children, it’s also right on the money. There’s often more than one way to be successful at a task. Remember when you find yourself in a conflict, that people see things differently and neither way is necessarily wrong.last_img read more


SOE Ministry demands assessment of halted high-speed railway project

first_img“We’re currently gathering information [regarding the project] in order to take further action,” he said.The Jakarta-Bandung High-Speed Railway project is one of the government’s national strategic projects (PSN) in the transportation sector and is expected to require a total investment of US$6.07 billion.The railway project will serve four main stations: Halim in Jakarta, Karawang in West Java and Walini and Tegaluar in Bandung regency. A total of 80 km of the railway will be elevated, while a further 16.9 km will be in tunnels.The trains will travel at 350 km per hour, cutting travel time between Jakarta and Bandung to 45 minutes, faster than the approximately three hours on the existing train. (mpr) The State-Owned Enterprises (SOEs) Ministry has demanded a full assessment of the Jakarta-Bandung high-speed railway project over environmental and human concerns.It also demanded consortium PT Kereta Cepat Indonesia China (KCIC), which is developing the railway, repair its drainage system. The system has been blamed for inundating the Jakarta-Cikampek toll road located near the project, causing traffic congestion in the area.“I’ve requested PT KCIC conduct a full evaluation regarding the weaknesses of project management that have caused environmental damage,” SOEs Minister Erick Thohir said in a press release on Monday. In a letter sent to PT KCIC on Feb. 27, the Public Works and Housing Ministry (PUPR) demanded the project be halted for two weeks starting from March 2, citing the project’s poor drainage system.Erick said the company must file a report in two weeks regarding its progress on drainage system repairs and environmental management.“We appreciate and fully support the PUPR Ministry’s action to halt the project for two weeks,” he said.Separately, the Transportation Ministry’s secretary-general Djoko Sasono said on Monday that the ministry would carry out an internal discussion regarding the issue before taking further steps.center_img Topics :last_img read more


Norway’s SWF manager backs move into private equity

first_img“A broader investment universe will thus not automatically mean that the Bank actually invests the fund in unlisted equity,” they said.“If the Ministry does permit unlisted equity investments, the Bank will approach investment opportunities and build expertise gradually, invest via and alongside others in a responsible manner that safeguards the fund’s ownership interests, and share relevant information with the public,” the men wrote.They said the detailed investment strategy for private equity would be set by Norges Bank’s executive board later on, based on more analysis.NBIM agreed with the ministry’s idea that the bank should have responsibility for deciding how much should be invested in private equity, as was the case with the fund’s allocation to unlisted real estate.Real estate was removed from the GPFG’s benchmark index from 1 January 2017, but the asset class remains part of the investment universe, effectively allowing NBIM to decide on the allocation up to a stipulated upper limit.NBIM said the ministry could set an upper limit for private equity too, and suggested this could be about 4% of the fund, or 6% of its equity portfolio.This was the allocation indicated if the fund’s stake in the private equity sector were to equate to its average stake in companies included in the benchmark for equity, it reasoned in the letter.“The Ministry could also choose to set a lower limit,” Olsen and Slyngstad added.The pair said it would “take a long time to build up a portfolio”.NBIM noted in its letter that other SWFs had allocated 8.5% of their capital on average to unlisted equity at the end of 2016, up from around 4% in 2000.Back in August, the ministry appointed two expert groups to review aspects of how the GPFG invests, including one to assess whether it should be allowed to invest in unlisted equities, and the other to analyse the performance of its active management. The manager of Norway’s giant sovereign wealth fund is recommending the government allows the fund to extend its investment universe to include unlisted equities.In a letter to the Norwegian Finance Ministry, the leaders of Norges Bank Investment Management (NBIM) suggested a cap of 4% on any allocation to private equity. This could amount to as much as €35bn based on the Government Pension Fund Global’s (GPFG) NOK8.5trn (€881bn) investment portfolio.The letter – signed by Øystein Olsen, chairman of the central bank Norges Bank, and Yngve Slyngstad, NBIM’s chief executive – was in response to a request from the ministry made at the end of June for the manager’s opinion on whether the investment universe for the fund should be expanded to include investments in unlisted equity.The pair emphasised that NBIM would only make investments if individual deals would help boost the fund’s overall risk-return profile.last_img read more


UK regulator heeds ESMA call for discretion over clearing obligation

first_imgIn a statement published yesterday, ESMA guided regulators “to not prioritise their supervisory actions towards entities that are expected to be exempted again in a relatively short period of time and to generally apply their risk-based supervisory powers in their day-to-day enforcement of applicable legislation in a proportionate manner”.The UK’s Financial Conduct Authority (FCA) today said it would not require pension schemes or their counterparties to start putting processes in place to clear derivatives in line with EMIR.“This approach is subject to any further statements that may be issued by ESMA or the FCA,” the UK regulator added. “We, in any event, continue to recognise that the clearing of derivatives is a prudent risk management tool.”ESMA cannot disapply a directly applicable EU legal text or delay the start of some of its obligations.PensionsEurope last month called for regulators to make clear that the clearing obligation would not be enforced for pension funds in the expected intermission between the exemption and any extension.“It is clear that both the Council and the European Parliament want to extend the clearing exemption and we expect them to wrap up negotiations pretty quickly,” said Matthies Verstegen, senior policy adviser at the association.“In the meantime, ESMA’s statement should be sufficient ground for national supervisors to allow pension funds to continue accessing the bilateral market. This is very reassuring as it would be difficult to deal with an unforeseen clearing obligation at the eleventh hour.”Both the EU Council and the Parliament have backed further exemptions for pension schemes, albeit for different lengths of time. The Parliament’s version proposed retroactively exempting derivative contracts executed during the gap between the EMIR exemption expiring and any new exemption kicking in. Europe’s top financial regulator has suggested to national supervisors that they do not force pension funds to abide by derivative clearing rules when an exemption expires next month.The European Securities and Markets Authority (ESMA) told regulators to “not prioritise” enforcing the rules introduced as part of EMIR. An extension of pension schemes’ temporary exemption from clearing rules – which would require them to hold cash against derivative positions – is under discussion as part of so-called “Refit” negotiations between the EU Council and the European Parliament.However, it is too late for an agreement on this to enter into force by the time the current reprieve runs out in mid-August.last_img read more

American energy-water desalination hub gets $100M kick-off cash

first_imgIllustration/Atmocean’s scaled wave energy system capable of producing both clean power, and fresh water from desalination (Photo: Atmocean) The US Department of Energy (DOE) has announced $100 million to establish an Energy-Water Desalination Hub that will focus on desalination R&D in low-cost alternatives that treat ‘non-traditional’ water sources to produce fresh water to cover the needs for the resource in the United States.The Hub will target early-stage research and development (R&D) of energy-efficient and cost-competitive desalination technologies, including manufacturing challenges, as well as the treatment of non-traditional water sources for multiple end-use applications.The “non-traditional” water sources, such as seawater, brackish water, and produced waters, will be considered for research as low-cost alternatives that could be exploited for use in municipal and industrial water supplies, or to serve other water resource needs through desalination.Rick Perry, the US Secretary of Energy, said: “By focusing R&D efforts on advancing transformational technologies that promote cost-effective desalination, we are working towards meeting the national and global need for secure, affordable water.”The DOE Office of Energy Efficiency and Renewable Energy’s Advanced Manufacturing Office will lead the Energy-Water Desalination Hub.The Hub team will work to achieve the goals of four technical topic areas, including materials research and development; new processes research and development; modeling and simulation tools; and integrated data and analysis.In March, Secretary Perry hosted a roundtable discussion at the White House to explore the use of prize competitions to drive technological innovation in critical water issues. DOE is working with interagency partners to develop prizes and associated R&D that will catalyze innovation at the nexus of energy and water.Energy and water systems are interconnected, according to DOE, as energy is required to extract, treat, and deliver water.On the other hand, water is used in multiple phases of energy production and electricity generation, from irrigating crops for biofuels to providing cooling water for thermoelectric power plants.Purifying water for these processes can be energy intensive and becomes more difficult as levels of saline increase. Successful research, therefore, can reduce demand on stressed freshwater supplies, according to DOE.Globally, fresh water scarcity is a major humanitarian and economic challenge that impacts all sectors of society, DOE warned.last_img read more


10 Keys to Healthy Living.

Wholesome eating and a healthy lifestyle can be surprisingly simple when a solid foundation of smart habits is in place. Here are ten useful tips you can easily incorporate into your day-to-day life.1. Be PreparedWhen it comes to establishing and maintaining nutritious eating habits, being well-prepared makes a world of difference. Set up a weekly time in your schedule to head to the grocery shop or the farmers’ market to ensure that your kitchen is well stocked with a variety of healthy foods for meals as well as convenient, portable snacks.2. Rearrange Your PlateLimit calories and boost nutrients by filling half your plate with fruits and vegetables. The other half of the plate can be split between lean proteins, such as fish, chicken, and tofu, and a mix of complex whole grains and carbohydrates, such as quinoa and sweet potatoes.3. Less Is MoreScan the ingredient list of all your processed foods, and seek out foods with short ingredient lists. Seek out foods with short ingredient lists. Ideally, most—if not all—of the ingredients will be easily recognizable. Try to minimize your consumption of processed and packaged foods.4. Keep a Food JournalMake a close assessment of what you’ve eaten in a typical week to affirm positive eating habits as well as to identify and tackle negative ones. Keep a food journal for three to seven days and choose small, strategic goals to work on, such as drinking more water or consuming two pieces of fruit and two different vegetables daily.5. Take CuesBe aware of when you’re hungry and when you’re full. Doing so will help keep portion size in check, which in turn will impact your weight loss or gain. Eat slowly—it takes 20 minutes for your stomach to tell your brain you are full—and aim to get fruit or vegetables into the majority of your meals.6. No Skipping MealsEating every three to four hours helps keep up your metabolism and calorie-burning ability. Make sure you have breakfast—even if it’s as simple as a piece of fruit and a skim latte—about one to one-and-a-half hours after waking, and at least one snack between meals per day.7. ExerciseTry to get at least 30 minutes of physical activity a day. Challenge yourself by changing your current routine: Add one extra day at the gym, go for a daily 30-minute power walk, take the stairs instead of the elevator, or add 10 to 15 minutes to your workout.8. Drink UpBoost energy and digestion by drinking water daily. Aim for at least six 8-ounce glasses and increase your intake according to your individual needs and physical activity level.9. Strive for BalanceHectic schedules are challenging, and they can affect our food choices. Reduce stress by taking care of yourself physically, emotionally, and mentally. Try to carve out some quiet time for yourself every day, even if it’s just 30 minutes.10. Sleep WellAn important physical component of maintaining good health is getting a sufficient amount of sleep. Along with physical activity and nutritious eating, proper sleep can help you manage sugar and carbohydrate cravings as well assist your efforts to achieve an ideal weight. Healthy adults should try for an average of seven to eight hours of sleep each night. Studies show that trying to recapture lost sleep on weekends simply doesn’t add up.by Epicurious.comlast_img read more
