The Avian Plight

In 1997, the world’s attention was caught by an alarming passage of Avian influenza from birds to humans in Hongkong. All chickens and ducks were killed upon the order of the Hongkong government to contain the spread of the deadly H5N1 virus.

Avian influenza or more commonly called as bird flu is an infection caused by avian (bird) influenza (flu) viruses. All birds naturally have these influenza viruses in their bodies. Wild birds have these viruses in their intestines but their bodies do not get infected or damaged by them. When passed on domesticated birds, avian influenza can cause sickness and death. Chickens, ducks, and turkeys are mostly hit by the   transmission  of avian flu among birds. Infected domesticated birds can pass on the virus to humans when they are eaten or consumed. *Migratory birds* infected with avian flu also become agents of viruses’ transfer from one place to another.

H5N1 carrier birds pass on the virus to other birds through their saliva, nasal excretions, and feces. Birds get infected when they come in contact with these contaminated excretions even by just staying on a surface or ground where virus carriers have stayed. Cages, dirts, water, feeds, infected waterfowl or other poultries that have been exposed to the virus are the common sources of infection among domesticated birds.

Two forms of bird flu exist among domesticated poultries infected with avian influenza viruses. The low pathogenic form is almost invisible and undetected for it causes only very mild symptoms that can be mistaken as non-avian flu effects. Manifestations of low pathogenic avian flu infection include low egg production or ruffled feathers. The second form of avian flu is the high pathogenic avian flu disease. This form leads to multiple organ failures and damages among infected birds. About 90 to 100 percent of birds infected with this form die within two days upon contamination. The spread of this form of avian flu is more rapid among birds in flocks.

Albeit basically a matter among birds, humans are also susceptible to bird flu or avian flu infection. The first known cases of humans getting infected with bird flu happened in Hongkong in 1997. 18 people were recorded to have acquired respiratory illnesses after having contacted infected surfaces from poultry farms, the infection claimed six lives.

The virus’ passage to humans that happened in Hongkong caused a global alarm. Health institutions worldwide raised concerns that the avian flu might be as damaging as the pandemic of flu that claimed about 20 million lives back in 1918. Reasonable enough, the fear and alarm are worth noting. What is essentially fearful is the idea that humans can be infected and actually die from a virus that is basically existing among birds only. The premise the Hongkong incident set is that the virus is mutating into something deadly for humans.

As of 2005, worldwide coordinated statistics recorded a number of 130 people having been infected of avian flu of which 67 have already died. In recent years, cases of human infection have been high in Asian countries. The World Health Organization believes that Asia is at higher risks since people live in close distance with domesticated birds like chicken and ducks. Animal domestication and poultry raising are common among many Asian countries who are agricultural by nature. What worries many is the common fact that humans have little or even a lack of immunity to the virus known to be infecting only (until the 1997 Hongkong incident) the birds.

An even higher cause of alarm has been found in recent studies on the H5N1 virus. Recent researches have shown that H5N1 strains have become more deadly among chickens and mice. This mutation is also found to be making cats or feline susceptible to the infection. H5N1 is also found to be resistant to some of the drugs used to treat flu (such as amantadine). New strains of the virus are also said to be possibly emerging especially in Asian countries.

What is now being focused on by scientists and health experts around the world is the prevention of human-to-human  transmission  which is believed to be the possible case that happened in Thailand in 2004. If it becomes widespread, human-to-human  transmission  is believed to be harder to contain that bird-to-human  transmission . Experts say that the virus’ continual change will make it hard for the human body to naturally develop immunity against the infection. The H5N1 virus is found to be changing over time through the changes happening in their structure called antigenic drift and antigenic shift. This continual change of the virus disables the immune system to respond accordingly whenever the flu virus enters the body. The only possible solution seen by experts is for infection-prone people to have a yearly immunization with up-to-date anti avian virus strains. But the big problem is, until now there is no medical treatment available to combat the H5N1 virus, making the yearly immunization update a far-fetched option.

How To Get Out Of A Low Sex Situation

The daily challenges in life, financial pressures, our jobs, taking care of kids, coping with aging parents and the like can take a toll on our desire for sex. This combines with the lack of sexual inventiveness can get us stuck in a sex rut which can hurt our desire. This can work in a vicious circle – low sex frequency leads to decreased sex drive and the depleted sex drive weakens the desire for sex.

How to get out of this situation so that you can have great sex again? Here are the 7 tips to help you to recover your sexual libido.

(1) Thinking about sex

If you hope to increase our interest in sex we have to take some time to flood our minds with sexual thoughts. This involves reliving those great sexual experiences you have with your spouse or to think of some new ways you can try to spice things up. You can also read some great articles or how-to help books or watch some informative videos, which can educate and allow you to know what is needed to improve sex life. The point here is to stimulate your mind in ways to get you into the mood.

(2) Increase your sexual attractiveness through dressing

The way you dress up yourself can play a great part in stoking those feel-good hormones, which can in turn influence your feeling of sexiness. How you look can influence how you feel. A changed outfit, a new fragrance, a makeover or a new hairdo can help to transmit the feeling that you are sexy and desirable. Even though you have grown accustomed to living with your spouse, this should not stop you from injecting some elements of surprise into the relationship, including the way you look.

(3) Communicating with partner

Sharing sexy words can be a great way for a sex-starved couple to reconnect and feel more inclined for romance. These words can be flowery, poetic and romantic like an old love letter or they can be spicy or graphic like a heated novel.

(4) Keep fit

Regular physical activity can boost the feel-good endorphins and can also improve your body image, promote blood flow to the sexual organs, making you feel sexier and giving your libido a healthy boost. In addition, Kegel exercises (done to tighten the pelvic muscles) can work to enhance sexual sensations and help boost desire.

(5) Spending time with each other

Just you and your partner only, separate from kids and work, during which serious topics such as kids and work are not discussed. You can plan a weekly date such as going out for dinner or a walk; but not to the movies or other activities that may not be conducive to talking to each other. If you cannot afford a babysitter, go out on the porch and have a glass of wine together after the kids go to sleep. You can also find some interesting and exciting things to do together such as going for tours, enrolling for some dancing or yoga classes.

(6) Allot some time to do something you enjoy

You can take time for yourself everyday even if this is only 10-15 minutes per day. This can help you to reduce stress and give you more energy for your partner. The more connected to who you are, the less you get lost in the daily grind, which pulls you away from your partner. The more sensual and the more connected you are to yourself, the more available you are for your partner.

(7) Just do it

If you have not had sex for a while, it is likely that your sexual desire will decrease gradually. The best way to overcome this is to have sex even when you are not in the mood at times. If you try to wait for the mood to come, chances are that you will never have sex again. Research has shown that the more we have sex, the more sex we want to have. Connecting sexually promotes the secretion of the attachment hormone, oxytocin, which can increase libido.

Best Cold Sore Treatment – What is A Successful Cold Sore Cure

In this article we will look at a few different types of medicinal remedies that are available and are considered to be the best cold sore treatment that is available today to achieve a cold sore cure.

1. Viroxyn

This is a new approach in helping to treat herpes and does not rely on the patient taking the medicine internally. It has been designed to specifically attack and disrupt the lipid coat of virus and is best described as being a germicide rather than the normal anti-viral treatment. Many say this is the top approach on the market.

As it is a virucide you apply it directly to the lesion and this will then kill the virus. This type of treatment works faster than many of the other types of drugs available which have to work their way through your stomach into the bloodstream and which are then able to deal with the sores and will only interefere with the viruses reproduction which has caused the eruptions in the first place. This is why some call it an effective remedy.

Unlike the other treatments that are available which will interrupt the genetic code of herpes and eventually stop the virus from growing, Viroxyn strips the lipid coating off the virus and then kills it when it comes into contact with an affected area.

2. Zovirax or Acyclovir

This is taken as an episodic treatment and can reduce the severity of the outbreak, as well as shorten its duration and also shorten the time during which the herpes virus is detected on the skin’s surface in a similar way to Viroxyn.

Because it is an episodic treatment it should be taken 5 times a day and can also be used as a suppressive treatment which will help to reduce the number of cold sore outbreaks a person has. If you wish to use it as a suppressive treatment you will need to take 2 tablets 3 or 4 times a day but it is best to speak to your doctor to get the specific dosage in order to treat the cold sores correctly. This medication has it’s own defenders as the best fever blister treatment on the market.

However with Zovirax there are a couple of common side effects which you may suffer from and these are nausea and diarrhea. When you consider a cold sore cure, you must keep in mind the side effects in making an evaluation.

We have provided details on a couple of the best cold sore treatments that available, but it is up to you to research both natural and prescription treatments and use a plan that you feel comfortable with in your search for a herpes cure.

At This Time What is the Best Treatment For Swine Flu? Disappointing News

At this time the best treatment for swine flu is prevention. Doing everything possible to avoid the flu may be more effective than the drugs and vaccine that we have (or maybe don’t have). The vaccine for H1N1 is scheduled to arrive in mid October but there will only be about 45 million doses and those will have to be doled out according to priorities set by your local health department.

The fact that we don’t have enough vaccine to go around may or may not be a problem. This vaccine was rushed into production and has not undergone the extensive testing that other vaccines have. The first question is will it work. The second question is what are the side effects. We won’t know those answers until late October.

There are two antiviral drugs available for flu, Tamiflu and an older drug Relenza. These drugs can be used to treat the flu or be used to prevent the flu in high risk populations like nursing homes. The good news is that the U.S. has at least enough stockpiled to treat 25% of the population. The bad news is that H1N1 might be immune to Tamiflu. In tests done in New York City last January, 99% of the H1N1 cases were Tamiflu resistant.

The other bad news about the drugs is that they work best when administered within 48 hours of coming down with swine flu. They won’t be prescribed unless the person tests positive for the strain. Now that the World Health Organization has stopped asking for test results, tests may or may not be given as readily as they were.

There are basically three types of tests. One can be completed in your doctor’s office in about 30 minutes. The problem with this test is it misses the flu roughly 30% of the time and also has a reputation of giving false positives. The other two tests require a lab. The actual test takes three hours to complete but add in transportation time and backlog and you’ll be lucky to see results in four days, two days longer than the recommended time to administer antivirals.

So the best answer to what’s the best flu treatment is, don’t catch it. If that doesn’t work; then your back to traditional treatment like fever medicine, rest, plenty of fluids, nutritious diet and Mom’s chicken soup.

This is going to be a big one and something you can’t ignore. It will affect your life either directly or indirectly. You need a plan on how to deal with it much as you would for dealing with an earthquake or hurricane.

Multi-Functional PACS Workstations

Digitizing medical imaging has changed the way medical facilities and hospitals function. Gone are the days of having to purchase film and costly developing chemicals for film images. With the advent of the DICOM digital image format, medical imaging was made possible. Today many medical offices utilize the flexibility that comes from PACS workstations and web-based PACS.

Storage of digital medical images is of vital importance, especially in light of medical facilities and hospitals needing to stay within HIPPA compliance. A PACS server helps to make this aspect of medical facility administration easier. A server takes up infinitely less space than hard copy film images do, plus it requires no physical maintenance of records. Everyone authorized to have access to the PACS server can set up their workstations to automatically send digital studies directly to the server, or to an offsite server that can be used for disaster recovery as needed, or copy the digital images to a CD or DVD.

With a web-based PACS, your medical facility and imaging center can save money while offering physicians greater flexibility in its use and overall better patient care. Doctors can log onto your local-area network, wide-area network, or from offsite by utilizing a virtual private network. Your medical offices will reduce operating costs because you will not need software for each workstation, and because it is web-based, physicians can access the digital medical images they need day or night in order to provide patients with excellent care.

Since a PACS system can also serve as a digital viewer, you will want to invest in a quality, high-resolution medical-grade PACS monitor. Monitors are available for medical use in a variety of sizes and digital image resolutions suitable for a variety of medical modalities. Ultrasounds, MRI, CT, as well as CR and DR digital x-rays can be viewed with a PACS monitor.

Medical facilities of all types will also save on consultations and referrals when using PACS workstations. Instead of using costly printed digital x-rays, you can send digital images stored in the DICOM format quickly and easily over the World Wide Web. This instantaneous   transmission  of patient medical digital images helps to offer them improved patient care while saving your hospital or medical office money.

PACS distributors and manufacturers can answer many questions you might have concerning PACS workstations; many offer live chat features on their informative websites for even more convenience.

Fax Machines Reviews

In the field of telecommunications, the word fax (facsimile) refers to the act of transmitting copies over a telephone network. This system enjoys a distinct advantage because the transfer is immediate. This machine consists of a modem and an image scanner. Sometimes, the equipment is equipped with printers and photo-copiers. Although these machines have existed since the last century, they began to gain popularity in the last two decades due to their economic affordability.

Digital fax machines gained popularity in Japan. In recent years, the internet has made inroads into the field of telecommunications but the machines have continued to remain a popular choice, even in the corporate world,for the transfer of documents. Fax servers have replaced the old fax machines. These can receive faxes and transmit the information over the internet to the user. There are two kinds of fax machines.

The analog machines used earlier, are no longer in vogue. Digital machines have replaced them. The digital machines have two groups, Group three and group four. The machines are classified on the basis of the time they take to transmit a document. There are also different classes of this machines and different transmission rates. These machines use a variety of modulation methods to transmit data. It use two different methods of compression to reduce the amount of data that needs to be transmitted between two machines. These methods are Modified Huffmann and Modified Read. In the Modified Huffmann method each word is scanned and compressed independently. The amount of white space is also reduced considerably. This helps in minimising the time taken for transmission. The Modified Read Method uses a slightly different method of compression.

The first line is scanned using the MH method. The second line is scanned and the differences are determined. These differences are transmitted after a process of encoding. This method pre-supposes that these differences are minimal. The Matsushita White Line Skip is another method of compression but it can be used only on Panasonic machines.

Most of the machines that are used currently belong to the Group Three. Documents are scanned in black and white. Thermal printers that were hitherto used have given way to a generation of this machines. Thermal transfer printers,laser printers and ink-jet printers are some of these machines. Thermal fax papers, however, do not possess legal validity as the ink used in these papers is not indelible.

Fax machines come now in compact sizes and are very portable. They are also all-in-one machines that lend themselves to official and personal use, that can print, scan and fax. These machines have become versatile and they are invaluable in any corporate setting or a business house.

Honda Motor Scooter Guide

Driving a car, truck or SUV can be pricey when you factor in the cost of rising gas prices. If you are a single motorist or only use your vehicle for commuting, an alternative to consider is a Honda motor scooter. There are currently six different models to choose from and of the various designs available, one is sure to meet all of your needs. Running errands around town, seating for two, storage space, long-distance riding and engine performance are just some options to consider when thinking about the kind of scooter you would like to be riding.

The Metropolitan model from Honda offers single seating for the modern rider. This scooter is perfect for the driver looking for sharp European design while being fuel efficient. Automatic   transmission  is also a perk for those who are new to riding scooters as shifting gears may seem intimidating.

Are you looking for a two-seat scooter with generous storage space and a little more engine zip than the Metropolitan? A Honda motor scooter that could be for you is the Honda Elite model. Reach speeds up to 50 miles per hour with its 108cc engine while riding comfortably with a second person seated behind you. And you do not need to worry about taking your helmet with you after reaching your destination with this model’s under seat storage feature.

Honda’s Ruckus model offers a rugged exterior as opposed to the smooth lines of the Metropolitan and Elite scooters. Automatic  transmission , a liquid-cooled engine and electric start are all features of this Honda motor scooter. Oversized tires allow for handling a bit rougher terrain while still enjoying the fuel efficiency that driving a scooter provides.

The PCX scooter offered by Honda engages a 125cc engine that can travel up to 60 miles per hour. A trunk allowing for a full size helmet and an accessory rack ensures you will have the space needed to accommodate all of the items you may be traveling with. Some highway travel is permitted with this motor scooter which may be a great option for commuters.

A sleek model that gets you from point A to point B faster and with room for two is Honda’s SH150i. This fuel-injected scooter features a 153cc engine and a Combined Braking System. A top speed of 65 miles per hour with two riders makes this scooter an ideal option for those looking for local and highway travel.

Finally, the Silver Wing ABS is the ultimate luxury scooter from the Honda line. An ample windscreen and seating for two offers comfort to all riders while the 582cc engine delivers power for those longer rides. The anti-lock braking system and automatic  transmission  offered with this Honda motor scooter model is sure to provide fast and fun transport for the motorist looking for ultimate comfort.

Understanding the Different Classes of Firewalls

For the enforcement and the tight control of security and the flow of traffic within and given network or between networks, the firewall is one very important piece of software and also hardware that is entrusted with these functions. An understanding of how the firewall is able to achieve its functions through the capabilities a firewall is able to provide. These are the capabilities which determine the type of firewall to be sourced to meet a certain and specific set of security needs.

Most of the firewalls will work through the packet filtering method which is one of the most effective methods of implementing security for the network through validation of data packets. The validation of the data packets is usually based on a number of factors which are the destination and the source internet protocol (IP) addresses, protocol, type of service, the source and the destination ports and port numbers, the differentiate services code point, the time range and a host of other parameters associated with the internet protocol header. These criteria are usually tested and matched for all individual packets so as to guarantee or deny these packets. This packet filtering comes about or rather is implemented through the use access control lists (ACL) which are found on switches and routers. The ACl has the advantage of being very fast when coupled with the application specific integrated circuit. Having seen these features of the packet filtering firewalls, the most obvious strong point for this type of firewall is that it is most common and can be found in about every component of the network. The packet filtering firewall is found in switches and routers as mentioned earlier, the wireless access points, the virtual private network aggregators are other devices on the network which use this type of firewall. The downside with the packet filtering firewall is that it is static and has been exploited by hackers who channel suspicious traffic through the TCP 80 port which grants unobstructed access.

The proxy firewalls also called the application firewalls work on a more complex model which can be explained by the Open System interconnection (OSI). This model seeks to explain the   transmission  of information from one computer to another application on a second computer. The information is passed through layers to make sure security is not compromised. The information according to the OSI model is passed through seven different layers starting with the application layer (7th layer) which is usually the interface in the form of programs used on the computer. The next layer is the presentation layer which is the translator between systems and converts the application layer information to a format acceptable to various different systems. Encryption is done in this layer.

The session layer is the fifth and manages service requests between computers. The transport layer provides reliable ordering and communication of data by preparing the data for delivery to the network  transmission  control protocol. The third layer is the network layer at which data is referred to as packet and this layer is responsible for routing and IP addressing. The data link layer handles the reliability of data which at this point is referred to as a frame. Finally, the first layer is the physical layer which is now composed of the devices which we can see as well as their electrical characteristics. The application firewalls work at layer seven which is the application layer just as the name suggests and they give a buffer often acting on behalf of a client. It is also patches easily in case vulnerabilities are identified. The only disadvantage is that they are slow in the manner that they handle data and traffic.

The next type of firewall is the reverse proxy firewall which will work in a similar manner to the application firewall. The difference lies in that the reverse proxy firewalls are deployed for the servers and not clients as in the case of application servers. The effectiveness of this firewall lies in the reverse proxy understanding how the application behaves and the intelligence to do away with problems like the buffer overflow.

A last form of firewall is the packet inspection firewall which takes care of session information and is even able to perform deep packet inspection to enforce compliance and scan for viruses all the time making sure that operation speed is superb.

These are the basic types of firewalls and which are chosen dependent on security needs and on to which many features have been added by different security vendors to make them better adapted for use.

Hansens Lepresy

Since the beginning of time, Hansen’s disease has been recognized as a problem. Reported in Egypt in as early as 1350 BC, Lepresy is the oldest disease known to man; this is according to the Guinness World Records. Frequently, Lepers have lived outside of society. This is partly due to the fact that for a long time the disease was believed to have been caused by a divine, often times associated with demons, curse or punishment. This idea changed in the middle ages, when people started to believe that lepers are loved by God, and that it is humans that have cursed them

Another reason for secluding the Lepers what that in the past it was believed that leprosy was highly contagious. If was even taken to the extent that leprosy could be spread by the glance of a leper or an unseen leper standing upwind of healthy people. Today we know that the disease is much less contagious than we once believed in the past. Lepresy is caused by a mycobacterium that will multiply at a very slow rate. The disease mainly affects the skin, nerves, and mucous membranes. The organism has never been grown in cell culture, because of the difficulty that is involved with doing so. This difficulty is as a result of the fact that the organism is an obligate intra-cellular parasite. This means that it lacks many necessary genes for independent survival. This is also evident and provides proof for it having such a slow rate of replication.

Uncertain today, is the method of   transmission  of Hansen’s disease. Many people believe that it is spread person to person in respiratory droplets. What we do know though, is that most of the population is naturally immune to the disease. The disease is chronic, and often times patients are classified as having paucibacillary, which is a form of multibacillary Hansen’s disease.
