Taste Bud Research

No Comments

first_imgMost people don’t give much thought to their 10,000 taste buds when they choose a chocolate chip cookie over an apple. University of College of Agricultural and Environmental Sciences researcher Hongxiang Liu thinks about these tiny sensory organs nearly every day. Liu, an assistant professor in the UGA Department of Animal and Dairy Science, has studied taste organs — the taste buds and taste papillae on which they reside — for more than 12 years to better understand the sense of taste and how it develops. She also plans to study the relationship between taste organs and obesity as a member of both the UGA Regenerative Medicine program and UGA Obesity Initiative. Researchers believe people’s ability to detect one of the basic tastes, such as sweet, could be related to the density of taste buds on their tongue. Under this assumption, a person with a greater density of taste buds would find a cookie sweeter than someone with a lower density of taste buds. “I think a better understanding of how taste papillae and taste buds are developed will help us to better understand how taste sensitivity is determined,” said Liu, who conducted research on taste at the University of Michigan before coming to UGA in September. Taste papillae are fingerlike projections visible on the tongue’s surface. Each papilla holds taste buds, which contain chemoreceptor cells. These cells send information about taste to the brain. Liu and her colleagues have identified several cell-signaling pathways, or sets of molecules involved in telling a cell what to do, that determine the pattern, density and size of taste papillae on the tongues of rats and mice. They also found the formation of the taste papillae can be altered by exposing the rodents’ tongues to different chemicals that affect these pathways. In a study published in Developmental Biology, Liu showed that one of the pathways involved in the development of taste papillae is the hedgehog-signaling pathway. The name refers to mutations in the pathway that cause taste buds of fruit flies — the organism in which it was originally discovered — to look spiky, resembling a hedgehog. “If I use a certain molecule to interrupt the hedgehog-signaling pathway at specific stages of development, the taste papillae will be everywhere on the rodent’s tongue,” said Liu, who was awarded a $1.25 million grant from the National Institutes of Health to further investigate the development of taste buds and taste papillae. She thinks the pathways involved in forming human papillae are similar to the ones she’s identified in rats and mice. A better understanding of these pathways and organs may provide a way to fight obesity. Cliff Baile, who directs UGA’s Obesity Initiative, hopes Liu can bring a new perspective to UGA researchers already studying eating behavior and food addiction. “As a taste developmental biologist, Liu brings a new area of research to the campus,” Baile said. Studying the way different foods or nutrients affect taste organ development could help researchers understand why the sense of taste differs among people. This knowledge also could help explain eating choices that lead to obesity. For example, people who are less able to detect the taste “sweet” might require more sugar to feel satisfied.last_img read more

Report: Dean Skelos Could Be Arrested Monday

Dean Skelos (R-Rockville Centre), the highest ranking senator in the state, and his son, Adam Skelos, may face corruption charges as early as next week, according to The New York Times.Skelos, the powerful senate majority leader, and his son are expected to be arrested next week on charges that may include conspiracy, extortion and solicitation of bribes, the Times reported, citing anonymous sources.The potential charges stem from an ongoing federal probe into corruption in Albany. The investigation is being led by Preet Bharara, the US Attorney for Manhattan, who has been steadfast in his pursuit to clean up the state capital.The announcement also comes three months after Sheldon Silver, the speaker of the New York State Assembly, was arrested for allegedly running a bribery and kick-back scheme that netted him nearly $5 million, prosecutors said.The expected charges could cause major upheaval in Albany, which for years was run by Skelos, Silver and Gov. Andrew Cuomo—a trio that has come to be known as “the three men in the room.”The Skelos’ probe centers around Adam’s business relationship with AbTech Industries, an Arizona-based company that was awarded a multi-million dollar contract by Nassau County despite it not being the lowest bidder, the Times reported.“The company, AbTech Industries, had hired Adam Skelos as a consultant,” the Times reported. “Prosecutors, some of the people said, have also focused on a $20,000 payment that a title insurance company, American Land Services, made to Adam Skelos, even though he never worked for the company.”“I have and will continue to cooperate with any inquiry,” Skelos said in a statement in mid-April. Several months earlier he criticized an NBC New York story that revealed Skelos was the subject of a federal investigation, calling it “thinly sourced” and “irresponsible.”The federal probe sparked an investigation by Acting Nassau County District Attorney Madeline Singas, whose Public Corruption Bureau is scrutinizing the county’s contracting practices.Nassau County Executive Ed Mangano was one of several local officials to testify before the grand jury in the Skelos case.“The County Executive and the County have been notified that they are not targets of the investigation,” Mangano’s spokesman Brian Nevin said at the time, “and will continue to assist law enforcement officials in the event they require additional information regarding the methodology of this public procurement process and the specifics of how the award determination was made.”Neither the US Attorney’s office or Skelos’ lawyer could be reached for comment.last_img read more

Huge fire breaks out at India gas well blowout

No Comments

first_imgThe company called for help from the army after locals allegedly attacked its vehicles after Tuesday’s explosion, spokesman Tridiv Hazarika said.Water was being pumped to the well over the past two weeks to prevent the gas catching fire.Assam’s Chief Minister Sarbananda Sonowal said firefighters, police and the army were being sent to the site, which is 500 kilometers east of Guwahati, the state’s biggest city.Environmentalists were increasingly worried about the impact of the gas leak. The well was producing 100,000 standard cubic meters per day (SCMD) of gas from a depth of 3,870 meters before the blowout in May, according to Oil India.Just one kilometer from the field is Maguri-Motapung wetlands, an ecotourism site. State-owned sanctuary Dibru Saikhowa National Park — renowned for migratory birds — is about 2.5 kilometers away.Authorities had established an exclusion zone of 1.5 kilometers and about 2,500 people had been evacuated from their homes.Officials Monday ordered a probe into the deaths of five people from the areas surrounding the field, although the district administration said a preliminary investigation suggested they died of natural causes. A huge fire broke out at an oil field near popular ecotourism spots in northeastern India on Tuesday, after gas that had spewed for two weeks from a blown-out well ignited, officials said.The gas well at an oil field managed by state-owned Oil India started leaking in late May in Tinsukia district of Assam state, and the firm said late last week gas was still flowing “uncontrollably”.Tuesday’s explosion sent bright orange flames and huge, black plumes of smoke high into the sky, visible 10 kilometers from the oil field, locals told AFP. Topics :center_img “While the clearing operations were on at the well site, the well caught fire,” Oil India said in a statement, adding that a firefighter suffered “minor injuries”. Around 200 engineers and workers — including a team of experts who arrived from Singapore on Monday — are trying to stem the leak within four weeks, the company added. Villagers fled in fear, and said five of their homes had caught fire.”The situation is very bad. It is spreading. I knew it was going to happen,” local environmentalist Niranta Gohain told AFP over the phone from the site.last_img read more

German investors hesitate to use sustainable definition

No Comments

first_imgKai Schulze, BVISchulze said “this is a huge problem for us,” as this timeline leaves just five weeks for institutions to define what a sustainable product is until the SFDR is implemented.BVI has entertained talks in Brussels and Berlin, recognizing how difficult it is to postpone the SFDR, but “we are open to other solutions. We need a signal that there is another solution, possibly quickly,” he added.Assets invested in sustainable funds in the German market have surpassed €100bn. In the first half of 2020, sustainable funds recorded net inflows of €7.2 bn, according to recent BVI figures.“If we can keep the growth rate in sustainable new businesses, then we have the opportunity at least to catch up with the top of the league very quickly in Europe,” Schulze said.As BVI supports the taxonomy regulation, it highlighted three main points as important to continue a positive trend in sustainable investments: a uniform definition of sustainable investments, data collection and the SFDR.To read the digital edition of IPE’s latest magazine click here. BVI has reiterated the need to postpone the implementation of the sustainable finance disclosure regulation (SFDR) to the beginning of 2022.“We as an association, and I think I also speak for the German financial world, demand to postpone the SFDR until January 2022,” Schulze said, adding that it would give the companies margin to implement the requirements.The technical standards on the methodology for disclosure will first be available at the end of January 2021 and the first company reports and investor disclosures using the EU taxonomy are expected at the beginning of 2022, according to the European Commission. German investors are hesitant to define their investment products as sustainable in view of the short amount of time given to design and define the characteristics of products under the upcoming EU taxonomy regulation.Kai Schulze, the head of the Berlin Büro at German fund industry association BVI, addressing the FNG Dialogue 2020 conference this week, said that “for some members in sales that they would not refer to the products as sustainable, and it is a shame for the trend [in sustainable finance] if sustainable products will not be distributed for a certain amount of time”.The SFDR regulation will apply from 10 March 2021 for financial market participants, including among others pension funds, investment firms and financial advisers, that will have to integrate relevant sustainability risks in their investment decision making processes.The new rules aim to improve transparency with regard to the integration of sustainability risks and adverse sustainability impacts of the investment processes and financial products.last_img read more

Avalon’s North End Beach Fill Works Complete Ahead of Schedule

No Comments

first_imgThe 2017 Avalon beach fill project will finish ahead of schedule and be completed in advance of Memorial Day weekend.According to Avalon Borough, nearly one million cubic yards of sand has been placed on the north Avalon beachfront in advance of Memorial Day weekend, and hurricane season which begins on June 1st.This $7.9 million beach nourishment project, one of the largest in Avalon, was financed largely with federal and state funding.“We are grateful to the Army Corps of Engineers, the New Jersey Department of Environmental Protection, and our neighbors in Stone Harbor for participating in this major capital improvement project that has saved municipal taxpayers several million dollars courtesy of our proactive approach to restoring the beaches,” said Avalon Mayor Martin Pagliughi.During the weekly project meeting held on Thursday, May 18th, Great Lakes Dredge and Dock Company announced that only 8,000 cubic yards of sand remained to be placed on Avalon’s north end beaches.This resulted in a total of 944,000 cubic yards of sand placed between the 9th Street and 30th Street beaches in Avalon as the work concluded during the afternoon hours of May 18th.During the early morning hours of May 19th, work began in front of the hotel district from 77th Street to 80th Street, along with the northerly limits of Stone Harbor. This additional volume in front of the hotel district will take approximately two and a half days to complete.Shortly after, in the mid-morning hours, GLDD reported a mechanical failure on the dredge “Texas” that results in the dredge being moved from Townsend’s Inlet to Cape May for repairs; those repairs will take about a week to complete.The beach project in southern Avalon and northern Stone Harbor will use a submerged pipeline that will be in the Atlantic Ocean pumping sand from the dredge “Texas” to the landing zone at Stone Harbor’s 84th Street beach.There will be approximately two blocks of beach closed in each direction as sand is pumped onto the southerly three blocks of beach front in Avalon as a 1,000 foot safety zone is required. The pipeline that exists on the beach in northern Avalon will be removed from the beach by GLDD via the 32nd Street beach path.The final phase of the beach project will consist of 305,000 cubic yards of sand to be placed in southern Avalon and northern Stone Harbor. The project will operate 24 hours and will only stop due to unsafe weather conditions or mechanical failure.[mappress mapid=”24099″]last_img read more

Dey leads Guyana’s ‘clean sweep’ of IGG male cycling road race

No Comments

first_imgBy Rawle Toney in Suriname IN dominating fashion, Guyana occupied the top four spots in the male cycling Road Race event to retain their Inter Guiana Games (IGG) Cycling trophy.Exceptional team work by the Guyanese resulted in Curtis Dey being able to have his way on the streets of Paramaribo, as he finished with a time of One hour, 47 minutes and 59 seconds (1:47.59) to finish first.His teammates then followed: Marcus Keiler was second (1:52.17), Jason Cameron (1:59.37) finished third and Adealie Hodge (2:02.52) came in fourth, to hand Guyana a convincing win and continued their rich tradition of winning the event.In the female event, however, Suriname came first while Guyana’s Sheneka Tiexeira was second, Deance Welch took third and Suriname rounded off the top four. Byonka Barker complained that a Surinamese deliberately “took her out” the race, resulting in her bicycle being damaged.Guyana’s Curtis Dey crossing the finish line to win the IGG Road Race yesterday in SurinameMeanwhile, having won the time trial the previous day, Guyana came out highly optimistic and it was Dey, the Trojon Cycle club member, who was urged by his teammates to ‘break out’ of the pack.Dey rode solo for much of the 69 Kilometers road race and so did Keiler who left Cameron and Hodge to hold the fort at the back.Cameron, who happens to be Dey’s teammate at the Berbice cycling club, later broke out and left Hodge to ‘toy’ with the Surinamese cyclist.However, Hodge would later on get tired of playing games and being urged by the Guyanese supporters, he would sprint away from the ‘pack’ and later joined his teammates in celebration.last_img read more
