Migraine Headaches What is a migraine headache? A migraine headache is a primary headache disorder that effects approximately 12% of the population. It is a headache that tends to recur in an individual and is moderate to severe if left untreated. It can be one sided, throbbing and aggravated by routine physical activity. It can be associated with light and sound and even smell sensitivity and many patients will become nauseated with it.. In a minority of patients there can be visual or sensory changes before, during or after the headache, known as auras. Who is affected by migraines? The National Headache Foundation estimates that nearly 30 million Americans suffer from migraines. What causes a migraine? The exact causes of migraines are unknown, although they are related to changes in the brain as well as to genetic causes. For many years, scientists believed that migraines were linked to the expanding (dilation) and constriction (narrowing) of blood vessels on the brain’s surface. Caffeine. Tension Fatigue
Working kidney created in bioengineering lab | Crave There just aren't enough donated organs to fill the need. That's why scientists have been dreaming of growing transplantable organs in labs. Scientists at the Massachusetts General Hospital Center for Regenerative Medicine have made a step forward by creating a functional rat kidney. The process is not quite as futuristic as growing a whole organ from scratch. The next step involves regenerating the organ by inserting viable cells from the recipient rat using a vacuum process. The organ is placed in a chamber that mimics the environment of a body. This isn't the first time researchers have developed bioengineered rat organs. Though the kidney work is promising, it's still early days. Ultimately, the process could turn nonviable organs into working organs that are designed to match each patient. (Via Txchnologist)
MedlinePlus: Headache Almost everyone has had a headache. Headache is the most common form of pain. It's a major reason people miss days at work or school or visit the doctor. The most common type of headache is a tension headache. Other common types of headaches include migraines, cluster headaches, and sinus headaches. Not all headaches require a doctor's attention.

The solution? A virtual private network, or VPN. A VPN extends your own private network into public places, so even if you’re using Starbucks' Wi-Fi connection, your Internet browsing stays encrypted and secure. There are plenty of ways to set up a VPN, both with free and paid services, but each solution has its own pros and cons, determined by the way the VPN provider operates and charges and the kinds of VPN options it provides. The easiest and cheapest solution to keep your data safe is to just abstain from public Wi-Fi completely. My Raspberry Pi is about the size of a smartphone, but it runs a fully functional VPN server. This is the part where I’d link you to a handy tutorial on how to set this up. Materials Hardware Raspberry Pi Model B: Plus everything that comes with it—by that, I mean a regular power source and a case to put it in. Software .
Brain-derived neurotrophic factor - Wikipedia, the free encyclop Brain-derived neurotrophic factor, also known as BDNF, is a secreted protein[2] that, in humans, is encoded by the BDNF gene.[3][4] BDNF is a member of the "neurotrophin" family of growth factors, which are related to the canonical "nerve growth factor", NGF. Neurotrophic factors are found in the brain and the periphery. Function[edit] BDNF acts on certain neurons of the central nervous system and the peripheral nervous system, helping to support the survival of existing neurons, and encourage the growth and differentiation of new neurons and synapses.[5][6] In the brain, it is active in the hippocampus, cerebral cortex, and basal forebrain—areas vital to learning, memory, and higher thinking.[7] BDNF itself is important for long-term memory.[8] BDNF was the second neurotrophic factor to be characterized after nerve growth factor (NGF). Tissue distribution[edit] Counterintuitively, BDNF is actually found in a range of tissue and cell types, not just in the brain. Mechanism of action[edit]
TypingTest Sea Hund & Katt Nightlife in Florence Clubs and pubs are everywhere in the city centre. Around the Cathedral and in other famous squares of the city you can find many small places to have a beer or a glass of the best Chianti wine.
