What You Need To Know About The Ebola Outbreak | Abc7.com

Health officials also suspect an "invisible caseload" in Liberia because new treatment facilities are filling with previously unidentified Ebola patients as soon as they open. Ebola Toll May 'Vastly Underestimate' Crisis US Hospitals and Colleges Taking No Chances Colleges will be screening students from West Africa for Ebola, according to the Associated Press . Some are testing students' temperatures and having private discussions with them about travel history. Hospitals and state labs across the country recently have reported dozens of possible Ebola cases to the U.S. Centers for Disease Control and Prevention.

Guest: Ebola Just One Of Many Infectious Diseases Ravaging The World | Opinion | The Seattle Times

These diseases are infecting people around the globe at an alarming rate. Currently, more than 35 million people are living with HIV, and every minute, six people under the age of 25 are infected with the virus. Tuberculosis is a worldwide health crisis, and second only to HIV/AIDS as the largest killer worldwide due to a single infectious agent. In 2012, 8.6 million people contracted tuberculosis, and 1.3 million died from the disease. Even as the battle to combat Ebola in West Africa and prevent its spread continues, the public cannot lose sight of the much larger struggle against infectious disease being waged today. Whether global media cover it or not, every day millions of people around the world are suffering from infectious diseases that still have limited treatment options and no known cure. The current Ebola outbreak has captured the attention of the world. But as I, and others in my field know too well, this is just one small battle in the war against a deadly foe. Greater awareness of the horrific impact these diseases wage on communities, families, parents and children every day would help ensure that the public is able to sustain the commitment and resources needed to eradicate infectious diseases from the world once and for all.

Boston Doctor Infected With Ebola In Stable Condition - News, Weather And Classifieds For Southern New England

Sacra, a doctor from suburban Boston who spent 15 years working at the Liberia hospital where he fell ill, said he felt compelled to return after hearing that two other missionaries with whom he'd worked were sick. Sacra, who served with the North Carolina-based charity SIM, delivered babies at the hospital, and was not involved in the treatment of Ebola patients, so it's unclear how he became infected with the virus that has killed about 1,900 people. Dr. Phil Smith, medical director of the Omaha unit, has said a team of 35 doctors, nurses and other medical staffers will provide Sacra with basic care, including ensuring he is hydrated and keeping his vital signs stable. The team is discussing experimental treatments, including using blood serum from a patient who has recovered from Ebola, Smith said. There are no licensed drugs or vaccines for the disease, but about half a dozen are in development. Rupp said he's unaware whether Brantley and Writebol have been asked about donating blood serum for Sacra. "These folks are friendly and know one another, and they would presumably be willing to help their compatriots," Rupp said, adding a battery of tests must first be performed, including one to ensure that any blood serum is compatible with Sacra's blood type Much attention has focused on the unproven drug ZMapp, which was given to seven patients, two of whom died.

Magnetic Detection Of Malaria Shows Promise - Scientific American

Other available detection techniques are not quantitative and are expensive or impractical to use in the field, especially in developing countries. Jongyoon Han, a bioengineer at the Singapore-MIT Alliance for Research and Technology Centre, and his colleagues, have devised a diagnostic test that avoids many of those problems. Their method, described in a paper published on 31 August in Nature Medicine , works with a tiny droplet as little as 10 microlitres of blood, and can provide a diagnosis in just a few minutes. In addition, it does not rely on the expertise of a technician. WhenP. falciparuminvades red blood cells and feeds on their contents, it breaks down haemoglobin into amino acids and haem, a chemical compound that contains iron.

Chikungunya Vaccine Performs Well In Early Clinical Trials - Health News - Redorbit

The candidate vaccine prompted a robust immunological response in recipients and was very well tolerated, noted Ledgerwood. Notably, the levels of neutralizing antibody produced in response to the experimental vaccine were comparable to those seen in two patients who had recovered from a chikungunya virus infection acquired elsewhere. This observation gives us additional confidence that this vaccine would provide as much protection as natural infection. The new vaccine is different from most typical vaccines because, rather than being made from killed viruses or weakened live viruses, this one is created from a virus-like particle (VLP) developed from the outer structural proteins of the West African strain 37997. Vaccines created from VLPs usually prompt an immune system reaction similar to that of natural, whole virus exposure. Dr.

Novartis Hands Over Experimental Tb Drugs In Antibiotic Pullback - Yahoo News

The TB Alliance deal reflects renewed scrutiny of the Novartis portfolio under new chairman Joerg Reinhardt, who is focusing the Swiss company's research on core areas such as cancer, respiratory drugs, heart failure and dermatology. While scientists are exploring novel avenues in the hunt for urgently needed new bacteria-fighting medicines, many companies now have little appetite for the chase, preferring to concentrate on more lucrative areas such as cancer and diabetes. "Novartis is not really focused on anti-infectives, so I think it makes sense," Kepler Cheuvreux analyst Fabian Wenner said of the licensing deal. Under the terms of Wednesday's agreement, TB Alliance will fund further research and development and be responsible for seeking approval and commercializing the TB treatments discovered at the Novartis Institute for Tropical Disease. NO UPFRONT PAYMENT "The goal of this agreement is to enable the program to be successful and bring needed medicines to patients," Novartis said in an emailed statement, adding that it had not asked for any upfront or milestone payments. Among the drugs Novartis is licensing is a class of medicines known as indolcarboxamides, which target drug resistant and multi-resistant strains of TB. One of the compounds, NITD304, works by blocking a protein that is essential for the TB bacterium's survival.

The Roots Of Our Ebola Fears - Cnn.com

The virus infects, say, a chimp or gorilla, and a human who has close contact with that animal becomes infected. Coming into contact with, or eating, the types of animals that become infected with Ebola would be a highly unusual scenario in the United States -- as unusual as mass human-to-human infection. Still, ambivalence is not the attitude we should have when it comes to diseases such as Ebola, says Wald, the "Contagious" author. We should have some level of deference to Ebola's virulence; it kills between 60% to 90% of the people it infects. At the same time, it must be acknowledged that becoming infected is difficult. "Should you be scared?

Gsk Seeks Regulatory Ok For World's First Malaria Vaccine - Upi.com

According the World Health Organization, the parasite infected 207 million people in 2012. Some 627,000 of those infected perished. Humans become infected with the disease via mosquitos which carry the parasite and transfer it when they bite. "This is a key moment in GSK's 30-year journey to develop RTS,S," said Sophie Biernaux , head of the company's malaria vaccine program. "And brings us a step closer to making available the world's first vaccine that can help protect children in Africa from malaria." Most of the world's malaria cases occur in Sub-Saharan Africa, but peoples of the tropics all over the globe are at risk. The CDC refers to the disease as "one of the most severe public health problems worldwide." The malaria parasite, which spawns the disease, produces more than 5,000 proteins during its lifetime, making it exceedingly difficult for researchers trying to figure which one to mimic in order to trigger an effective immune response from the body. But scientists seemed to have finally located a combination of proteins that works, and if the EMA offers their approval, the drug will soon be available to some of the world's most vulnerable populations. RTS,S has shown promise in trials ever since its earliest development in the 1990s.

As The Games Begin, Deadly Floods Threaten World Cup Host City | Thinkprogress

Iran is scheduled to play Nigeria in Curitibas Baixada Arena on Monday, followed by Spain versus Australia on June 23. Across the state of Parana more than 33,000 people were forced from their homes. While deadly floods are not uncommon in Brazil, the timing of the latest deluge is bizarre. Flooding mostly occurs in Brazil during the summer rainy season. Brazils winter months, May to August, are usually mostly dry. This is just the latest in a series of climate-related events that have plagued Brazil over the last few months as final preparations for the World Cup have been underway. January and February, which usually bring the years heaviest rains to the country, were extremely dry and hot, and sparked fears of water rationing and power shortages as hydroelectric reservoirs dwindled. Brazil depends on hydropower for two-thirds of its energy.

Some Uses For An Adiabatic Calorimeter In The Lab

Heat is among many parameters measured in the calorimetry lab; or any laboratory for that matter. Among the instruments made use of in the measurement of heat in these labs is an adiabatic calorimeter.

Throughout a chemical response, reactants are converted into items. If the reaction needs heat to develop these products, the response is called endothermic. Heat flows into the system, causing the reactants to convert to products. If the response creates heat it is thought about to be an exothermic response. It is typically desirable to determine the magnitude and direction of the heat flow for a certain response.

The process made use of to determine this heat flow is called calorimetry - this is the science of measuring the heat of chain reaction or physical modifications along with heat ability and is the focus of work done in a calorimetry laboratory. Clicking the following link takes you to a web site specialists in thermal analysis and the instruments used to obtain these measurements Click.

Differential scanning calorimeters, isothermal microcalorimeters, titration calorimeters and sped up rate calorimeters are a few of the other usual kinds of calorimeters. A basic calorimeter includes a thermometer connected to a metal container that teems with water and suspended above a combustion chamber. Measuring the heat flow in a response needs a closed system, specifically a calorimeter or relying on the application, an adiabatic calorimeter.

This kind of calorimeter is made use of to analyze a reaction that is out of control. In most systems that are without unique safety measures, the system not only exchanges enthalpy with its surroundings, but likewise experiences a change in its temperature level. To avoid the issues this can produce, thermochemists utilize these well insulated instruments in the calorimetry laboratory, keeping the transfer of energy (and enthalpy) as heat across the border in between the calorimeter and its surroundings successfully no during the experiment.

Because the calorimeter runs in an adiabatic environment, any heat generated by the sample being checked causes a boost in temperature level, which then fuels the reaction. The adiabatic calorimeter is never entirely adiabatic, considering that some of the sample heat will always be lost to the sample holder.

Ultra-sensitive calorimetry is an essential technique for molecular-level study and product screening. It is important in the analysis and development of pharmaceutical and polymer products in the modern-day calorimetry lab. Although it saves analysts, chemists and engineers a significant quantity of time and money, it is probably among the finest kept item development keys.

Calorimetry also plays an important duty in biotechnology applications by supplying researchers with essential data on the thermodynamics, structure, stability and functionality of proteins, nucleic acids, lipids and other biomolecules. It is also an essential study tool in the pharmaceutical, genetic, energy and product fields. Calorimetry in general and the adiabatic calorimeter in specific can be used in any area that requires the measurement and controlled manipulation of elements and communications at the molecular level.

A calorimetry laboratory allows researchers and product designers to gather thermodynamic info that was difficult or challenging to acquire utilizing previous generations of instruments techniques. These calorimeters are especially helpful due to the fact that of the amount and precision of the information they remove, as well as their capability to get information making use of very little samples.

Led Lighting - Cool In More Ways Than One

The appeal of using LEDs in lighting applications is proliferating. The numerous and considerable advantages of making use of modules that include a matrix of LEDs are being acknowledged by design engineers in a number of crucial industry sectors, including aerospace, architectural lighting, and the "gold egg" vehicle market.

Qualities such as design versatility, reduced power consumption, even and reputable light, and long life time distinguish LED modules from designs based upon conventional filament lamps and fluorescent tubes. LEDs can likewise have knock-on benefits, such as considerably reducing the size and intricacy of the module and simplifying the lens design.

An excellent example of some other benefits of LED lighting is demonstrated by an application in the cabin of a passenger aircraft. A retrofit LED device that changed a fluorescent-tube lighting module made it possible for carefully regulated dimming and also offered mood lighting through the use of differently colored LEDs.

Thermal management

Perhaps the most challenging concern when realizing a module design that makes use of LEDs is to handle the temperature level of specific device junctions throughout regular operation. If the substantial quantity of heat produced by all the gadgets in a module is not managed correctly then the junction temperatures may reach a level where the LEDs' anticipated life is reduced and dependability is compromised The following link takes you to a web site specialising in thermal analysis and the instruments used to get these measurements http://www.thornta.com.

LED modules generally make up a matrix of many surface mount gadgets. These LEDs are soldered to an etched copper layer that offers the interconnects in between the specific LEDs along with other passive and active components that are required to finish the circuit. The little size of the LEDs and the close distance with which they can be mounted means that designers have a huge amount of design flexibility and can achieve complex lighting patterns with high levels of brightness.

The etched copper circuit is separated from a base plate - typically made from aluminum - by a thermally effective, electrically isolating dielectric material. The characteristics and abilities of the dielectric layer are crucial to the design versatility and efficiency of the general module.

Dielectric materials are made by mixing thermally reliable materials such as alumina and boron nitride with other ingredients, to offer a resistant yet versatile covering on the base plate. A crucial quality of the dielectric layer is the length of electrical isolation it supplies in between the copper on the topside and the metallic base plate on the underside. This is known as its dielectric strength. A common dielectric material might have a dielectric strength of around 800 V/mil and be covered onto the base plate to a density of 8-12 mils (1 mil = 1 inch-3 = 25.4 µm).

Dielectric products utilized on insulated metal motherboard generally have a thermal conductivity figure in the area of 3W/mK. This is around 10 times the performance accomplished by FR4 (flame retardant woven glass strengthened epoxy resin) PCB material.

A further main requirement of the dielectric layer is to be able to make up for the different coefficients of thermal expansion of the copper track on the topside of the assembly and the aluminum base plate/heat spreader on the bottom side.

Going three-dimensional

Flat sheets of insulated metal circuit board making up copper foil, a dielectric layer and an aluminum base plate have been readily available for numerous years. In the eyes of the forward-thinking LED module designer, the primary issue has actually been that flat sheets of insulated metal motherboard restriction them to 2D shapes.

To resolve this restriction, brand-new dielectric materials are appearing that have a low modulus, meaning that they are certified with mechanical stress and strain. These materials not only accommodate the coefficient of expansion of the metal aspects of the construction, however likewise allow parts to be formed into right angles, and even through 360 Ë?. This allows designers to understand complex-shaped designs and ones that form a total circle with either external or internal copper traces.

When developing with brand-new, formable insulated metal motherboard materials it is possible to path the tracks around edges, which alleviates the have to utilize connectors and hard wiring. There are numerous benefits to this, consisting of enhanced dependability arising from having less interconnects and junctions. In spite of the a little greater expense of the new products, the total cost is decreased due to the fact that less parts are required, and assembly time is decreased.

Strength and durability

LEDs themselves are inherently durable. Mounting them on metal based motherboard only serves to boost their effectiveness and that of the completed module, providing exceptional resistance to vibration and mechanical shock.

Automotive lighting clusters provide a good example of exactly how LED modules can supply remarkable efficiency compared with conventional filament lights. On-vehicle applications experience high levels of vibration and broad operating temperature ranges that can cause early failure of filament lights. In some operating conditions LEDs can last approximately 100,000 hours, meanings that they should not need any attention for the life of the car.

The long life of LEDs also simplifies the designers' task due to the fact that it is less essential to make the lighting module available for servicing in the final product. This can lead to a neater, more incorporated installment and also in possible expense savings.

Temperature level modelling

Thermal analysis software application bundles are offered to help show LED based module designs prior to they are committed to make.
These software packages collect information from an integrated database about LED performance and requirements in addition to those of various other devices that are mounted on the insulated metal motherboard. This data is incorporated with other details about elements of the design, consisting of the copper traces, power and ground planes, and vias. The collated info is then processed to produce a precise representation of the thermal performance of the design.

User-friendly graphical representations of the results make it possible for the design engineer to rapidly determine locations that could require attention, right down to element and track level.

Thermal analysis software can bring considerable industrial and design benefits by assisting speed the time to market and lowering the number of versions required to reach a production-ready solution.

If You're Involved In Medicine Development Then Polymorphism Should Be Of Interest

The consequences of Abbott Laboratories' antiretroviral drug Ritonavir, utilized to deal with HIV infection and AIDS and issues with polymorphism has yet to be generally comprehended. Avoiding action has not yet commonly been researched on polymorphism by the international pharmaceutical industry, so it is worth retelling the story.

In 1996 Abbott introduced into the market a reliable protease inhibitor Norvir ® that had cost the company over $200 million to develop. The drug was formulated as an encapsulated ethanol/water solution. In the summertime of 1998, supplies of the drug were disrupted by the unexpected appearance of a brand-new crystal type (polymorphism) at a plant in the USA and then later on at a plant in Italy. This new, more thermodynamically stable polymorphic type had really different physical characteristics than the earlier material and Abbott was compelled to withdraw the drug from sale. The brand-new form failed dissolution tests and precipitated out within the capsules. The company lost an estimated $250 million in sales along with hundreds of millions of dollars trying to recuperate the original polymorph while the item was off the marketplace. No doubt many AIDS patients were not helped by the item's absence. What appeared to have taken place was that a degradation product obtained throughout production had initiated the look of a second crystalline form, a second polymorph.

So exactly what is polymorphism? It is merely an alternative plan a molecule could take on in a crystal. Most medicine molecules are crystalline. That is, the molecules pack together in a certain regular method. Some molecules, maybe the majority of, have the ability to pack together in more than one way and therefore offer increase to various polymorphs. A pair of polymorphs may have very different physical characteristics. Over 50 % of all Active Pharmaceutical Ingredients (APIs) exist in a minimum of 2 polymorphic types.

During medicine development, an initial searching polymorphism screen is made to discover a stable non-solvated kind with excellent properties. A later extensive polymorphism display is to discover as lots of types as possible in order to extensively cover the Intellectual Property space. Constant monitoring is required throughout development in order to ensure ongoing control of polymorphism.

What can trigger polymorphism modifications? Crystallisation from various solvents could generate various crystal types or solvates. Extremes of humidity or heat are among the more obvious elements impacting polymorphism. Modifications in polymorphism can also be induced as a repercussion of a number of typical phases of API processing such as granulation, melting, spray drying out, compression and milling that are required to produce the final dosage form.

X-Ray Powder diffraction and Raman spectroscopy are the 2 workhorse approaches used to examine the presence and length of various polymorphic kinds found throughout screening. Differential Scanning Calorimetry (DSC), Differential Thermal Analysis (DTA), Dynamic Vapour Sorption (DVS) and hot stage microscopy are added specialised techniques utilized to characterise different polymorphic forms.

All is not doom and gloom as the polymorphism properties of a chemical element are patentable. A brand-new polymorphic type for that reason may be made use of to extend the patent life of a drug. A counter to this is that a new polymorphic type with useful characteristics may have the ability to replace a current medicine and successfully 'bust' the initial patent.

It's not surprising to discover that makers & developers of generic drugs actively pursue brand-new polymorphic forms of patented drug compounds. This can be an extremely litigious area.

National regulatory authorities require that all companies register the accurate polymorph of any new medicine. Furthermore, producers should show that each polymorph is steady and can be reliably recreated

Many little pharmaceutical business do not mean taking their drug prospects all the method to commercialisation themselves however to seek to accredit at an earlier phase. This arises due to the fact that of the significant boost in costs as a medicine moves through the clinic. If a polymorph display is likewise included then the bundle is definitely more powerful and the licensor can expect an additional premium.

Throughout pre-clinical development the amount of an API that is available for studies is normally really low. Evaluating a wide range of conditions and solvents requires to be conducted for that reason on a really small scale. Systems that can manage numerous experiments at the milligram scale are best. At some labs automated systems can handle around 96 well plate formats and perform experiments at 0.5-2mg scale. Hence the total quantity of API utilized for an initial display can be a modest 50-200mg.

Typically, a salt choice task will precede a polymorphism research: as soon as a salt is found that has the most promising properties, it will be more established, characterised and might be the topic of an additional polymorphism display during the normal course of pre-clinical development.

Polymorphism, in addition to complicating medicine development likewise assists medicine efficacy and can guarantee that any hard made work is justifiably rewarded.

Oil And Grease Life Estimates - Forecasting Lubricant Life In Bearings

Bearing Oil and Grease Life Study

Exactly how should we estimate and predict the lube life of the items we utilize in the automobiles we service. Well, we all comprehend the principles of friction. Heat and impurities are the greatest adversaries of bearing grease and oil. Think of all the parts that require lube, from bearings to internal Engine Component Parts. In Bearings there are 3 kinds of lubricating substances: Synthetic oils, mineral oils and grease. Synthetics last longer at raised temperature levels. Many have unique reduced temperature level and reduced flammability homes. Numerous likewise have homes that have the tendency to take in water (hydrolysis), but this excellent function likewise has the tendency to reduce the life of the majority of phosphates, silicates and ester artificial oils. I hope I am not losing anyone here.

But this is crucial so please remain with me. Avoiding hydrolysis can be accomplished with special additives, desiccated air or filtration with triggered alumina or clay based fullers Earth. What type of Synthetic and mineral oils exist? Silicones, Alkyl silicates, alkyl phosphates, mineral oils, Polyglycols, Polyphenyl ethers, Silicones, Poly Esters, Synthetic hydrocarbons and Diesters.

Mineral oils weaken rapidly when they oxidize or respond chemically with dissolved oxygen. This enhances the oil level of acidity causing varnish looking deposits, this reduces bearing life. Additives can extend oil life by disturbing oxidation domino effect. You can enhance protection by adding additives as this procedure happens. Exactly how do you know when to alter it? You can check it electrochemically, micro scale oxidation test, differential thermal analysis, or high-pressure differential scanning calorimetry. Grease consists of thickening material ingredients as well as consists of oil, either synthetic or mineral? As soon as 1/2 of its oil content is gone, a grease can fail. In this case noise from the bearing will notify you.

Floods Possible Across Northern Colorado With More Rain This Afternoon - The Denver Post

The river was one foot above its 7.5-foot flood stage Saturday afternoon. The Poudre river is expected to crest at 8.4 feet Sunday morning but isn't likely to go back below flood stage until Monday afternoon, the National Weather Service said. The river could rise to base of the bridge at College Avenue in Fort Collins, forecasters said. Large hail and damaging winds are possible, and there's a chance the system could spawn brief tornados, the National Weather Service said. As has been the routine over the past two weeks, isolated and scattered thunderstorms are expected to move across northern Colorado and the Front Range Saturday afternoon and early evening. The National Weather Service issued a severe thunderstorm warning until 3:45 p.m. Saturday for central El Paso County, with the risk of quarter-size hail. A flash flood warning was issued in the county until 5:30 p.m., but was canceled at 3:30 p.m. More than a dozen Colorado counties were under flood warnings or advisories Saturday because of the combination of heavy rain and the peak of the high country snowmelt, the service said. A small stream and river flood advisory is in effect until 9:15 a.m.
