Answer» eter can be used to measure the rate of transpiration that’s proportional to water uptake. Transpiration cannot be measured directly as some of the water will be used in photosynthesis. The rate of transpiration can be calculated by MEASURING the distance travelled by an air bubble in a CAPILLARY tube over a given TIME. The faster the bubble MOVES, the greater the rate of water uptake – and so the greater the assumed rate of transpiration. |

Story based on the moralof biodiversity conservation |
|
Answer» brewed coffee on a lazy weekend morning. Children drawing pictures or blowing out the candles on their birthday cake. Lingering over a home-cooked meal, enjoying conversation late into the night. The kitchen table is the scene for some of the simple, innocent joys of life.But could you enjoy them in the same way if you knew species were dying out as their rainforest home was destroyed to PROVIDE the timber for your table? What if indigenous people were moved off their land to get at the wood your table was made from?When you walked into your local furniture store 20 years ago, you had little way of knowing where the timber in your table came from. Today, THINGS are different. With the FSC label, you can buy a table – not to mention chairs, flooring, garden sheds, wallpaper, toilet tissue and much more – safe in the knowledge that you’re not threatening the countless species and people that depend on the world’s forests. Facts and stats50% – proportion of the world’s tropical forests destroyed over the last centuryFour-fifths – area of the AMAZON still standing15% – proportion of global greenhouse gas emissions resulting from DEFORESTATION and forest degradation9 out of 10 – land-based species found in forests60 million – indigenous people living in tropical forestsWhat next?At the moment, net forest loss (the amount cut down compared to what’s re-grown) stands at 52,000 sq km a year. Our goal is to reduce the net loss to zero by 2020. But we’ll be honest in our accounting, and won’t pretend that a monoculture plantation offsets the loss of a pristine forest. We’re doing that by focusing on the underlying causes of deforestation – and finding solutions. In particular, we’re looking at three large tracts of tropical rainforests – in the Amazon, the Congo Basin and Borneo.Our appetite for beef is one of the biggest threats to the Amazon, as land is cleared to make way for grazing and to grow soy for cattle feed. We’re working with the beef and soy industries, and the big global retailers they supply, to adopt more sustainable practices.Illegal and unsustainable logging remains a big problem. WWF fought for and HELPED win important legislation in the United States and Europe banning the import and sale of illegally harvested and endangered wood. We’re also promoting responsible forestry through the FSC, which maintains forest quality and guarantees social benefits for local people.In Indonesia, huge areas of forest are being cleared to make way for palm oil. By promoting sustainable palm oil, we’re protecting the forests while helping people earn a better living. Tropical forests are a huge asset for developing countries – but we need them to be worth more standing than cut down. We’re supporting schemes that pay countries and local communities for providing the service of carbon storage for the benefit of all humanity. |

How to calculate percentage inhibition of paw volume in collagen induced arthritis |
|
Answer» of this study is to evaluate the analgesic and anti-inflammatory activities of atorvastatin and simvastatin in different experimental models in mice and rats. Materials and Methods: Analgesic ACTIVITY of simvastatin and atorvastatin was assessed in tail flick model in rats (n = 6), where it was compared with aspirin and tramadol and in acetic acid induced writhing in mice (n = 6), where it was compared with aspirin. Anti-inflammatory activity of statins was evaluated using carrageenin induced paw edema and formalin induced arthritis in rats. Results: In the tail flick method, analgesic effect of tramadol was significantly more than the other drugs except at two observation times, when it was comparable to simvastatin and atorvastatin. Effect of simvastatin was found to be comparable to aspirin. In acetic acid induced writhing method, analgesic activity of simvastatin was comparable to that of aspirin while that of atorvastatin was significantly less. In carrageenin induced paw edema in rats, both simvastatin and atorvastatin showed anti-inflammatory activity which was comparable to aspirin. Both the statins exhibited significant anti-inflammatory activity (P < 0.01) in formalin induced arthritis model though less than aspirin (P < 0.05). Conclusion: The results of this study if substantiated by further experimental and CLINICAL research suggest that simvastatin and atorvastatin may play an adjuvant role, which may be particularly beneficial in the treatment of inflammatory disorders, especially when there is coexisting dyslipidemia. KEY WORDS: Formalin induced arthritis, paw edema, statins, tail-flick method, writhing Go to: Introduction Drugs commonly used in modern medicine for suppression of pain and inflammation like non-steroidal anti-inflammatory drugs and corticosteroids provide only symptomatic relief. Long-term use of these drugs is associated with serious adverse effects. Hence, the search for a new, safe analgesic and anti-inflammatory drug is ONGOING. Introduced in 1980, statin group of drugs are most efficacious and well-tolerated in the treatment of hyperlipidemia. Statins are widely used for the prevention of cardiovascular diseases. Although the beneficial effects of statins in preventing cardiovascular diseases may derive from their lipid-lowering activity, these drugs have also been shown to possess anti-inflammatory and immunomodulatory effects.[1] Indeed, several recent studies have demonstrated the ability of diverse statins to prevent chronic inflammation in vivo, and one clinical trial has shown the beneficial effects of atorvastatin in patients with rheumatoid arthritis.[2–5] Statins have been shown to decrease the secretion of pro-inflammatory cytokines IL-6 (interleukin-6) and IL-8 (interleukin-8) from macrophages, and inhibit the release of the chemokine CCL2/MCP-1 (macrophage chemotactic protein-1) from these cells.[6,7] The molecular mechanisms sub serving such anti-inflammatory and/or immunomodulatory activities are unclear. Osteoarthritis is a common disorder that causes severe pain and immobility in the patient. Treatment of osteoarthritis in modern medicine is currently limited to drugs that provide only symptomatic relief, and these drugs are associated with serious adverse effects. Hence, research for finding a better and safe drug for osteoarthritis has been a continuous process. Patients of hyperlipidemia are often overweight and more likely to suffer from osteoarthritis.[8] Considering various reports about anti-inflammatory and analgesic activity of statins, it is worthwhile to further evaluate these activities. Atorvastatin has also been evaluated for its anti-inflammatory and analgesic activities; however, the results are controversial.[9] During our literature search we did not come across any study that evaluated the analgesic activity of simvastatin. Hence, this study was planned to evaluate and compare the anti-inflammatory and analgesic activities of simvastatin and atorvastatin in different animal models of inflammation and pain. Go to: Materials and Methods Animals Adult Wistar albino rats (Rattus norvegicus, weighing between 180 -280 g) and Swiss mice (weighing between 25–30 g) of either gender were used. Animals were kept in cages in temperature-regulated rooms with air-cooling and 12 hours light and dark cycle, and had free access to water and standard laboratory diet. They were allowed to acclimatize to the laboratory conditions for a PERIOD of one week, and kept fasting overnight prior to the experiment. The study was approved by the Institutional Animal Ethics Committee and all the experiments were performed as per the Committee for the purpose of control and SUPERVISION on experiments on animals (CPCSEA) guidelines.

|
Answer» ophs are bacteria and archaea that fixatmospheric nitrogen gas into a more usable form such as ammonia.[1][2][3][4][5][6][7][8]A diazotroph is a microorganism that is able to GROW without external sources of fixed nitrogen. Examples of organisms that do this are rhizobia and FRANKIA (in symbiosis) and Azospirillum. All diazotrophs contain iron-molybdenum or -vanadium nitrogenasesystems. Two of the most studied systems are those of Klebsiella pneumoniae and Azotobacter vinelandii.
