How Vitamin D May Affect Heart Disease, Diabetes - eMedicineHealth

Vitamin D deficiency has been linked to heart disease and type 2 diabetes. Chronic inflammation plays a role in both of these diseases, and most immune cells have receptors for vitamin D. Binding of vitamin D to its receptor regulates many key processes inside cells. However, the mechanisms connecting activation of the immune system with these diseases aren't well understood.

How often to change air filter for ac unit

What Happens When You Forget to Change Your Filter

So you know you’re supposed to change your air filter regularly, generally every three months or even more frequently. But, life happens and often changing filters is something that we store in the back of our minds as we think about day-to-day life—work, kids and our social lives—and we might just forget.So what’s the danger in this? How will forgetting to change your air filter affect you, your family and anyone else who enters your home?Problem #1: You’ll experience a poorer quality of air in your home.Air filters & AC filters works to trap harmful particles like mold, pet dander and bacteria that would otherwise pollute the air in your home. If a filter isn’t changed in due time, it will simply run out of room to collect more of these contaminants.Say you spill some juice. You grab a paper towel and cover the spill. After the first paper towel becomes too saturated to absorb more juice, you throw it away and grab and second one to continue cleaning up the spill. That second paper towel is necessary to keeping your home clean in the same way a new filter is.Problem #2 : Your HVAC system will work less efficiently, or not at all.In short, when you forget to change your air filter, contaminants like pollen and dust clog the filter and keep it from doing its job—cleaning the air that circulates throughout your home. And preventing your filter from doing the work it was deigned to do, not only keeps your HVAC system from doing the same, but also may harm it. and adds up to indoor air pollution which very harmful.Your HVAC system is powered by a fan motor that will have to work harder and harder to push air through a clogged filter. This additional pressure may cause the fan motor to overheat or even break entirely. Replacing a broken HVAC system will cost you—but so will letting an HVAC system run with a dirty filter. More work for the fan motor translates to higher charges on your electric bill. Additionally, a dirty evaporative (cooling) coil can dramatically reduce your airconditioners performance.Problem #3: You’ll inadvertently make your home dirtier.If your air filter becomes too clogged, the dust and dirt particles that it won’t be able to trap will simply recirculate throughout your home. This means dirt will collect quickly on surfaces within your house. Chances are, if you notice you’re dusting more frequently, it’s time to change your filter. No one wants to live in a dirty home, and cleaning more is certainly a pain, but it’s important to remember that the worst part of having more dirt in your home comes from breathing in that dirt. Failing to change your filter means living in an environment that will negatively affect your family’s health—especially if they have allergies, weak immune systems or other medical conditions.Furthermore, failing to change your filter can be negative for the environment as a whole. Remember, how clogged filters make your HVAC system work harder? As they expend more energy, your carbon footprint increases.Though changing your air filter may be an easy task to forget, it’s one that is important for your family’s health. You want to make sure the air they breathe is clean, especially if they suffer from allergies or conditions like asthma. If you need help remembering to change your air filter, try setting an alarm on your phone or marking your digital or paper calendar. Or you might align changing your filter with other important events on your calendar. Find one chore that you do every 3 months or more frequently depending on your needs, and plan to change your filter at the same time. If you’re noticing more dust in your home, or having more trouble with allergies than usual, you can take the hint that perhaps it’s time. When in doubt, just take your air filter out and see how dirty it looks. Changing your filter may be hard to remember, but the good news is, it’s a quick and easy way to improve your quality of life.

Introduction to immunology | McMaster Pathophysiology Review

Microorganisms that cause disease in humans and animals enter the body at different sites and produce disease symptoms by a variety of mechanisms. Microbial invasion is initially countered by innate defenses that preexist in all individuals and begin to act within minutes following encounter with the infectious agent. Only when the innate defenses are bypassed, evaded or overwhelmed is an adaptive immune response required. The innate immune system (IIS) is usually sufficient to prevent the body from being routinely overpowered by these organisms. However, once they have gained a hold, they require the concerted efforts of both the IIS and the adaptive immune system (AIS). In the first part of this chapter, different arms and principles of the IIS and the AIS will be briefly discussed.  The second part of the chapter will discuss the process of fighting a bacterial and a viral infection, with an emphasis on the cross talk between the two parts of the immune system.
