Our focus on Digital combined with our investments in client mining have resulted in strong growth in top accounts.” Wipro had earlier guided for a dollar revenue growth of negative 2 per cent to zero per cent for the June quarter.Revenues fell 2.6 per cent quarter-on-quarter to Rs 13,626 crore from Rs 13,987.50 crore in the March quarter. Morgan Stanley had estimated Wipro’s net profit at Rs 1,992 crore on revenues of Rs 13,459 crore for the June quarter. IT services EBIT margins dropped to 16.8 per cent in June quarter from 18.8 per cent in March quarter.The IT major said it sees IT services revenues at $1,962-$2,001 million in the second quarter, implying minus 0.5 per cent to 1.4 per cent growth.Profit from the key IT services business declined 5.8 per cent year-on-year to Rs 2,190 crore or $339 million. Operating margin from IT services was 16.8 per cent for Q1.The Bangalore-based IT outsourcer also announced a share buyback to the tune of Rs 11,000 crore at a price of Rs 320 per share. In the previous financial year, it had announce buying back of 40 million shares or 1.62 per cent of the shares, amounting to Rs 2,500 crore at Rs 625 a share.On new order wins, Wipro said, it won a multi-year engagement with a large utility company in the United States to deliver data center, disaster recovery, service desk and end user services. “This program will drive greater automation and improve services to end customers through the use of analytics and the Wipro HOLMES Artificial Intelligence Platform,” the company said.Wipro also bagged a multi-year contract from a Europe-based oil and gas major to transform their IT infrastructure and security platform.On Wednesday, Wipro Chairman Azim Premji had said at the company’s AGM that IT companies will find more business opportunities at a time when technology is a differentiator.Premji said that there is a drastic change in expectations and experiences of consumers and business models. “Digital is the central element driving this change. We believe that IT Services companies are key to deliver Digital to enterprises,” Premji said.He pointed out that this transition will depend on Wipro’s ability to redefine and align with this new global paradigm and disruptive development in the industry. “In this context, we have made significant investments, organic and inorganic, in transforming our business offerings to serve the new demand from clients,” he said.last_img read more

Coral Reefs In The Gulf Dodged Harveys Bullet – For Now

first_img Share Courtesy Adrienne CorreaA diver studies coral reefs at the Flower Garden Banks National Marine Sanctuary in the Gulf of Mexico.Scientists think the Tax Day Floods in 2016 had a negative impact on the Flower Garden Banks, a diverse ecosystem of coral reefs in the Gulf of Mexico. So, Hurricane Harvey must have been even worse on them, right? Not necessarily.Researchers from NOAA and several Texas universities have studied the coral reefs in the Gulf, and, so far, they haven’t seen the same kind of damage from all the freshwater runoff after Harvey that they saw in the months following the 2016 floods.Several months after the Tax Day Floods, there was a mass mortality event on the reef, according to Adrienne Correa, an assistant professor of ecology and evolution at Rice University. But researchers like her are still trying to learn exactly what caused it. The cause could’ve been all the fresh water from the floods disturbing the salty conditions the coral need to thrive – or something else.So, in October, when Correa and other researchers took water samples and dove down to the Flower Garden Banks, they thought maybe they’d see a similar result. But that was not the case.But why not? Correa says further study is still needed. She and other scientists are busy analyzing their samples from the site. But, she says wind and ocean circulation patterns could’ve kept all that fresh water from getting to the banks this time.She said scientists have much better data leading up to and after Harvey compared to the Tax Day Floods. So, they can compare the two events and better determine if certain microbial signatures match up and learn exactly what caused the 2016 mortality event.Courtesy Adrienne CorreaA researcher prepares to dispatch machinery to take water samples from the Flower Garden Banks coral reefs in the Gulf of Mexico.Regardless of the cause, it’s important to keep tabs on the health of the Flower Garden Banks because they’re some of the highest coral-cover reefs left in the Atlantic and Gulf. They harbor some of the most diverse marine life species in the ocean, and they’re important to many industries – such commercial fishing and diving. And she says problems could still surface in the coming months. If all that fresh water from Harvey had come down on the Flower Garden Banks, the outcome could’ve been dire.Correa and Dr. Michelle Johnson from the Flower Garden Banks National Marine Sanctuary talk with Houston Matters host Craig Cohen about the health of the site after Harvey.last_img read more

Overcoming multiple herbicide resistance

first_img Journal information: Proceedings of the National Academy of Sciences A new way to use herbicides: To sterilize, not kill weeds Explore further Black-grass and rye-grass are considered by farmers, to be weeds. They are not only invasive—causing reduced yields in fields where they mix with crops—but can also harbor ergot, a type of fungus that can spread to crops, killing them. For these reasons, farmers have used herbicides to keep the grasses at bay. Unfortunately, the grasses have begun to develop immunity to the toxins traditionally used to kill them. In this new effort, the research group has found what appears to be the source of the plants’ new-found strength, and perhaps, a way towards creating a new way to kill them.Specifically, the team found that a gene called AmGSTF1, appears to be responsible for causing overproduction of an enzyme called glutathione transferase. In plants, the result is the production of more than normal amounts of antioxidants, which help ward off the toxins meant to kill them. The team made this discovery by adding the AmGSTF1 gene to thale cress, which does not have MHR. Doing so, they found, caused the thale cress to become just as resistant to herbicides as black or rye grass. Interestingly, the same enzyme has been found to be at least partly responsible for doing something similar with tumors that grow inside of humans. Because the enzyme has been known to help tumors in humans fight off toxic drugs, researchers have developed another drug called 4-chloro-7-nitro-benzoxadiazole—it blocks the production of glutathione transferase and as a result makes tumors easier to kill. Because of that, the researchers studying the invasive grasses tried spraying it on the thale cress that had been made resistant to herbicides and found that doing so caused it to lose its new-found abilities and to be once again susceptible to the chemicals meant to kill them. Unfortunately for farmers, the same drug cannot be used on invasive weeds because it’s toxic to people as well. But, the researchers suggest another similar drug might be developed that could do the job without harming those that eat the crops the farmers are trying to protect.

Although poorly understood, in common with multiple-drug resistance (MDR) in tumors, MHR is associated with an enhanced ability to detoxify xenobiotics. In humans, MDR is linked to the overexpression of a pi class glutathione transferase (GSTP1), which has both detoxification and signaling functions in promoting drug resistance. In both annual rye-grass and black-grass, MHR was also associated with the increased expression of an evolutionarily distinct plant phi (F) GSTF1 that had a restricted ability to detoxify herbicides. When the black-grass A. myosuroides (Am) AmGSTF1 was expressed in Arabidopsis thaliana, the transgenic plants acquired resistance to multiple herbicides and showed similar changes in their secondary, xenobiotic, and antioxidant metabolism to those determined in MHR weeds. Transcriptome array experiments showed that these changes in biochemistry were not due to changes in gene expression. Rather, AmGSTF1 exerted a direct regulatory control on metabolism that led to an accumulation of protective flavonoids. Further evidence for a key role for this protein in MHR was obtained by showing that the GSTP1- and MDR-inhibiting pharmacophore 4-chloro-7-nitro-benzoxadiazole was also active toward AmGSTF1 and helped restore herbicide control in MHR black-grass. These studies demonstrate a central role for specific GSTFs in MHR in weeds that has parallels with similar roles for unrelated GSTs in MDR in humans and shows their potential as targets for chemical intervention in resistant weed management. (Phys.org) —British scientists from several research facilities across the country have found that an enzyme called glutathione transferase which is known to neutralize toxins meant to stem the growth of tumors in humans, also appears to be responsible for helping two kinds of invasive grasses develop multiple herbicide resistance (MHR).
