Dopamine is the one neurotransmitter that everyone seems to know about. Vaughn Bell once called it the Kim Kardashian of molecules, but I don’t think that’s fair to dopamine. Suffice it to say, dopamine’s big. And every week or so, you’ll see a new article come out all about dopamine.
A good starting point for any scientist in any field is to recognize that there is much we do not know. We do not know, for example, why there is more matter than antimatter in the universe. We do not know very well how the evolution of the dinosaurs filtered out. And, perhaps most surprising of all is that we do not know very well how many organs the human body has or what all its functions are.
Aortoiliac occlusive disease (AIOD) occurs commonly in patients with PAD. Significant lesions in the aortoiliac arterial segment are exposed easily by palpation of the femoral pulses. Any diminution of the palpable femoral pulse indicates that a more proximal obstruction exists. Obstructive lesions may be present in the infrarenal aorta, common iliac, internal iliac (hypogastric), external iliac, or combinations of any or all of these vessels. Occasionally, degenerated nonstenotic atheromatous disease exists in these vessels and may manifest by atheroembolism to the foot, the "blue toe" or "trash foot" syndrome. Generally, patients with aortoiliac PAD have a poorer general prognosis than those with more distal PAD.
A talus fracture is a break in one of the bones that forms the ankle. This type of fracture often occurs during a high-energy event, such as a car collision or a high-velocity fall. Because the talus is important for ankle movement, a fracture often results in significant loss of motion and function. In addition, a talus fracture that does not heal properly can lead to serious complications, including chronic pain. For this reason, many talus fractures require surgery.

A peak flow meter is an inexpensive, portable, handheld device for those with asthma that is used to measure how well air moves out of your lungs. Measuring your peak flow using this meter is an important part of managing your asthma symptoms and preventing an asthma attack.
Bovine respiratory disease (BRD) has a multifactorial etiology and develops as a result of complex interactions between environmental factors, host factors, and pathogens. Environmental factors (eg, weaning, transport, commingling, crowding, inclement weather, dust, and inadequate ventilation) serve as stressors that adversely affect the immune and nonimmune defense mechanisms of the host. In addition, certain environmental factors (eg, crowding and inadequate ventilation) can enhance the transmission of infectious agents among animals. Many infectious agents have been associated with BRD. An initial pathogen (eg, a virus) may alter the animal’s defense mechanisms, allowing colonization of the lower respiratory tract by bacteria.

Atherosclerosis is a narrowing of the arteries caused by a buildup of plaque. It’s also called arteriosclerosis or hardening of the arteries. Arteries are the blood vessels that carry oxygen and nutrients from your heart to the rest of your body. As you get older, fat and cholesterol can collect in your arteries and form plaque. The buildup of plaque makes it difficult for blood to flow through your arteries. This buildup may occur in any artery in your body and can result in a shortage of blood and oxygen in various tissues of your body. Pieces of plaque can also break off, causing a blood clot. Atherosclerosis can lead to heart attack, stroke, or heart failure if left untreated.
At each level of the spine, there is a disc space in the front and paired facet joints in the back. Working together, these structures define a motion segment (Fig. 1A). Back pain may result when injury or degenerative changes allow abnormal movement of the vertebrae to rub against one another, known as an unstable motion segment (Fig. 1B). Two vertebrae need to be fused to stop the motion at one segment. For example, an L4-L5 fusion is a one-level spinal fusion (Fig. 1C). A two-level fusion joins three vertebrae together and so on.
Scar revision includes techniques that improve the appearance of an unsightly scar, regardless of its size, type or age. This is typically not covered by insurance carriers and is treated as a cosmetic procedure. Though scars can never be completely removed, the appearance of scarring can be greatly diminished. Who Should Get Scar Revision? The best candidates for scar revision are in good health and have realistic expectations. Scar revision may be used to treat: Hyperpigmented scars Large or plainly visible scars Keloid scarring Raised scars Deep depression scars After scar revision, the appearance of your scar should be greatly reduced. Scar revision can improve the size, shape and color of your scar. Multiple procedures may be needed to achieve optimal results. There are several different techniques that can be used during your scar revision. During a consultation, we can discuss the best techniques and determine if you are a suitable candidate. What to Expect During Your Scar Revision Your scar revision may involve one or more of the following techniques: Topical treatments (gels, creams, external compression) can treat mild scarring or changes in pigmentation. Injectable treatments like dermal fillers are best for filling in scar depressions. These treatment options can provide long-lasting improvements, however, they are not always permanent. Surface treatments like chemical peels, dermabrasion, laser therapy and skin bleaching can improve skin tone and texture. More than one treatment may be needed to achieve optimal results. Surgical scar revision is only used in more severe cases. Reconstructive techniques like Z-plasty, tissue expansion, or skin grafting replace a prominent scar with a less noticeable scar. After Your Surgery Scar revision recovery varies depending on the procedure you have elected. Topical and injectable treatments rarely require downtime. Surface treatments and surgical removal can require several days of recovery. You may experience some temporary bruising, swelling, or discomfort. Over-the-counter or prescription medication can be used to manage pain. Topical and injectable treatments are likely to require sustained application to maintain results. The final results of surface treatments and surgical removal may not be visible for several weeks to months. It is important to protect the treatment area from direct sun exposure for several weeks. Additional details about your specific recovery will be discussed during your consultation.
