In order to investigate the potential of Platycarya strobilacea fruit extract as an active ingredient for cosmetics, we measured their free-radical scavenging activity, elastase inhibitory activity, the expression of MMP-1 (matrix metalloproteinase-1), and type I collagen synthesis in normal human fibroblast cells. To isolate the main component compounds from P. strobilacea fruit extract, we purified the extract through solvent fractionation, column chromatography, and recrystallization. The component compounds were identified as ellagic acid and 4-0-xyloside of ellagic acid (ellagic acid 4-0-xylopyranoside). P. strobilacea fruit extract and ellagic acid increased the expression of type I collagen mRNA in a dose-dependent manner (up to 37% and 41% at 20 μg/ml and 1.0 μg/ml, respectively), comparable to that of ascorbic acid (up to 39% at 500 μM). A clinical study of measurements using visual evaluation and image analysis showed a statistically significant difference (p < 0.05) between the effects of the test and placebo products. This result suggests that P. strobilacea fruit extract could be used as an active ingredient for antiaging cosmetics.

The aloe vera plant has a long history of safe use for oral and topical applications. This publication describes safety studies conducted on a proprietary high-purity aloe vera inner leaf fillet preparation, Qmatrix®. In a 13-week study in rats, Qmatrix® was administered via gavage at 0, 500, 1000 and 2000. mg/kg body weight (bw)/day. There were no significant changes in food or water consumption, body weight, serum biochemistry or hematology at any of the doses tested. Sporadic, significant increases were observed in some of the measured urinalysis parameters; however, these variations were not treatment-related, as most were observed only in one sex, not dose-dependent and within historical control values. Organ weights were unaffected, except for a statistically significant, though not dose-dependent, increase in absolute and relative weights of the right kidney in males at 500 and 2000. mg/kg bw/day, respectively. Histopathological analysis revealed no abnormal signs. Qmatrix® was non-mutagenic in an Ames test and a chromosomal aberration test at concentrations up to 10,000 μg/plate, and in an in vivo bone marrow micronucleus test at doses up to 5000. mg/kg bw/day. Based on these results, Qmatrix® is not genotoxic in vitro or in vivo and; has an oral NOAEL greater than 2000. mg/kg bw/day following 90. days of oral exposure. © 2010 Elsevier Inc.

A total of 26.1. Mg of residual waste from 3129 households in 12 Danish municipalities was analysed and revealed that 89.6. kg of Waste Electrical and Electronic Equipment (WEEE), 11. kg of batteries, 2.2. kg of toners and 16. kg of cables had been wrongfully discarded. This corresponds to a Danish household discarding 29. g of WEEE (7 items per year), 4. g of batteries (9 batteries per year), 1. g of toners and 7. g of unidentifiable cables on average per week, constituting 0.34% (w/w), 0.04% (w/w), 0.01% (w/w) and 0.09% (w/w), respectively, of residual waste. The study also found that misplaced WEEE and batteries in the residual waste constituted 16% and 39%, respectively, of what is being collected properly through the dedicated special waste collection schemes. This shows that a large amount of batteries are being discarded with the residual waste, whereas WEEE seems to be collected relatively successfully through the dedicated special waste collection schemes. Characterisation of the misplaced batteries showed that 20% (w/w) of the discarded batteries were discarded as part of WEEE (built-in). Primarily alkaline batteries, carbon zinc batteries and alkaline button cell batteries were found to be discarded with the residual household waste. Characterisation of WEEE showed that primarily small WEEE (WEEE directive categories 2, 5a, 6, 7 and 9) and light sources (WEEE directive category 5b) were misplaced. Electric tooth brushes, watches, clocks, headphones, flashlights, bicycle lights, and cables were items most frequently found. It is recommended that these findings are taken into account when designing new or improving existing special waste collection schemes. Improving the collection of WEEE is also recommended as one way to also improve the collection of batteries due to the large fraction of batteries found as built-in. The findings in this study were comparable to other western European studies, suggesting that the recommendations made in this study could apply to other western European countries as well. © 2013 Elsevier Ltd.

Bulky waste is a significant and increasing waste stream in Denmark. However, only little research has been done on its composition and treatment. In the present study, data about collection methods, waste quantities and treatment methods for bulky waste were obtained from two municipalities. In addition a sorting analysis was conducted on combustible waste, which is a major fraction of bulky waste in Denmark. The generation of bulky waste was found to be 150-250?kg capita?1 year?1, and 90% of the waste was collected at recycling centres; the rest through kerbside collection. Twelve main fractions were identified of which ten were recyclable and constituted 50-60% of the total quantity. The others were combustible waste for incineration (30-40%) and non-combustible waste for landfilling (10%). The largest fractions by mass were combustible waste, bricks and tile, concrete, non-combustible waste, wood, and metal scrap, which together made up more than 90% of the total waste amounts. The amount of combustible waste could be significantly reduced through better sorting. Many of the waste fractions consisted of composite products that underwent thorough separation before being recycled. The recyclable materials were in many cases exported to other countries which made it difficult to track their destination and further treatment. © International Solid Waste Association 2012.

Zimbabwe’s mobile payment solution that enables Econet customers to send or recieve money to loved ones, buy prepaid airtime and pay for goods and services EcoCash has recieved approval to operate cross border remittance service from South Africa. The firm and its South African partners have been approved by the South Africa Reserve Bank, the he central bank of South Africa and the country’s financial services regulator. The service which took over 18 months to be secured is expected to go live in a few weeks will see Zimbabweans living in South Africa to send money directly to any Econet Wireless number anywhere in Zimbabwe via EcoCash. This will be a major relief for Zimbabweans working in South Africa who reportedly find it hard to send money back home to their friends and relatives. “By making the process of sending money from South Africa highly accessible, quicker and more convenient, Zimbabweans living in South Africa will be able to send remittances of even less than R50 at affordable rates,” announced the firm. In a statement on its site, Econet says it predicts the new service to fundamentally change the remittance patterns characterized by large, lump sum transfers of around R1 000 being sent monthly or every several months. The firm is also hoping the “micro-remittance” solution will stimulate increased remittances into Zimbabwe which will help ease liquidity challenges in the economy.

Bargain hunters rejoice. Econet Zimbabwe is now selling 1GB of data for $1 and 3GB for $2. Those are the new prices of the Econet Dream Data Bundles that were introduced last month in the Zimbabwe. Econet is determined not to lose its stranglehold on the Zimbabwean broadband market with this latest offer, which makes it the cheapest mobile broadband package on the market. The Dream Bundles also had their access window extended from a previous midnight to 5am window, to a new 10 pm to 8 am window. That’s a 1-2 punch by the telco giant. And the winner is… the customers.

…As court judgment reinstates Econet’s equity. A FRESH tussle over equity at Airtel Networks, before the courts since 2003 may now shift to the boardroom as a result of a judgment by the Federal High Court sitting in Kaduna, presided over by Justice Shuaib in the matter of equity claim of five per cent by Econet Wireless Ltd in Airtel Networks Ltd. But the telecoms operator has said that it has filed an appeal against the judgment, while reiterating that said judgment will have no impact on the holdings of other shareholders in Airtel Nigeria. Six days ago on January 24, Justice Shuaib delivered his judgement on a matter which has been before the courts since 2003, and ordered that: Airtel should reinstate the five per cent (5%) shareholding of Econet Wireless Ltd (EWL);lAll actions, and resolutions taken by the company since October 2003, at which EWL was entitled to be notified, and to participate in, as a shareholder, but was prohibited, are null and void. This includes decisions to sell shares, issue shares, and also transfer shares to third parties. The name change from Econet Wireless Nigeria Limited, effected in 2003, was irregular, and must be reversed forthwith. Justice Shuaib further ordered the Corporate Affairs Commission (CAC), to cancel any certificate previously issued for the change of the name of the company and restore the name of the company to Econet Wireless Nigeria Limited. But in a statement posted on Econet Wireless International’s portal, dated January 30, Strive Masiyiwa, Econet’s supremo said: “It is universally accepted throughout the world, that when shares in a company are allotted and share certificates issued, as confirmation of ownership, this is sacrosanct. “In October 2003, Econet Wireless Ltd received a letter from the chairman of the company — Mr Oba Otudeko, in which he advised that at a board meeting directors had decided that Econet Wireless was no longer a shareholder, Econet’s share certificate had been cancelled, and Econet’s name removed from the shareholder register. The motive for this unprecedented action was the circumvention of Econet Wireless’ rights as a shareholder in order to facilitate the sale of shares, first to Celtel International, and later to Bharti Airtel. “As a result of these actions, Econet Wireless was left with no option but to seek redress through the courts. An application was filed in the Nigerian Federal High Court in October 2003, more than eight years ago. Since then, every legal avenue to delay the process was pursued by the defendants through their lawyers, in order to frustrate Econet Wireless. “I am very disappointed that whilst it was clear to Celtel, Zain and Bharti Airtel that Econet Wireless was a shareholder, they still chose to pursue a path, in which the end justified the means. It is clear even to those with the most basic understanding of company law that the board of a company has no power in any jurisdiction to simply cancel the shares of a shareholder but their desire to own the company was so great that they were prepared to overlook the facts and ignore our rights. “The substance of this ruling, which was known by Celtel and then Bharti, was a matter of record in the legal documents of the company. It is also common cause to even the casual reader that the order given has far-reaching consequences on the current ownership status of the company. We have made it clear to the company, that as a shareholder, we would like to ensure that all actions that must be taken to comply with the court order are undertaken in such a way that there is minimal disruption to the ongoing operations of the company.” While opting to appeal the judgment, in a statement issued by Emmanuel Otokhine, the telco’s Head of Public Relations, the management of Airtel Nigeria said. “In the light of the judgment by the Federal High Court of Nigeria regarding Econet Wireless Limited’s (EWL) claim to the ownership of 5% equity in Airtel Networks Limited (Airtel Nigeria), an appeal against the said judgment has been filed by Airtel Nigeria. The company abides by and has full confidence in the law of the land, and believes the Appeal Court will determine the appeal on its merits. “In addition, the judgment will have no impact on the equity holding of other shareholders in Airtel Nigeria. “We wish to assure our customers, employees and business partners that the ruling will in no way affect operations or the company’s ability to fulfill obligations to its stakeholders.” But it would seem that both parties will have to come to the negotiating table at the end of the day to marshall options for the future. This much is evident in the position taken by Masiyiwa in the statement posted on Econet’s website. “The board of Econet Wireless and I remain willing to sit down with Bharti Airtel, to review the best way forward for all parties. In the meantime, we have a fiduciary responsibility to take all of the necessary steps to vigorously protect the interests of our shareholders.”
