Outline the methods of behavioral genetics studies and the conclusions that we can draw from them about the determinants of personality. Explain how molecular genetics research helps us understand the role of genetics in personality. One question that is exceedingly important for the study of personality concerns the extent to which it is the result of nature or nurture. If nature is more important, then our personalities will form early in our lives and will be difficult to change later. If nurture is more important, however, then our experiences are likely to be particularly important, and we may be able to flexibly alter our personalities over time. In this section we will see that the personality traits of humans and animals are determined in large part by their genetic makeup, and thus it is no surprise that identical twins Paula Bernstein and Elyse Schein turned out to be very similar even though they had been raised separately. A gene is the basic biological unit that transmits characteristics from one generation to the next. These common genetic structures lead members of the same species to be born with a variety of behaviors that come naturally to them and that define the characteristics of the species. These abilities and characteristics are known as instincts—complex inborn patterns  of behaviors that help ensure survival and reproduction(Tinbergen, 1951). Birds naturally build nests, dogs are naturally loyal to their human caretakers, and humans instinctively learn to walk and to speak and understand language. Rabbits are naturally fearful, but some are more fearful than others; some dogs are more loyal than others to their caretakers; and some humans learn to speak and write better than others do. Personality is not determined by any single gene, but rather by the actions of many genes working together. Furthermore, even working together, genes are not so powerful that they can control or create our personality. Some genes tend to increase a given characteristic and others work to decrease that same characteristic—the complex relationship among the various genes, as well as a variety of random factors, produces the final outcome. Furthermore, genetic factors always work with environmental factors to create personality. Having a given pattern of genes doesn‘t necessarily mean that a particular trait will develop, because some traits might occur only in some environments. For example, a person may have a genetic variant that is known to increase his or her risk for developing emphysema from smoking. Studying Personality Using Behavioral Genetics Perhaps the most direct way to study the role of genetics in personality is to selectively breed animals for the trait of interest. In this approach the scientist chooses the animals that most strongly express the personality characteristics of interest and breeds these animals with each other. If the selective breeding creates offspring with even stronger traits, then we can assume that the trait has genetic origins. In this manner, scientists have studied the role of genetics in Attributed to Charles Stangor Saylor. Although selective breeding studies can be informative, they are clearly not useful for studying humans.
In this scenario buy generic naltrexone 50 mg line, it presents with ipsilateral Horner syndrome and contralateral ischemic motor deficits generic 50mg naltrexone. Other causes of acute Horner syndrome include (ie buy naltrexone 50mg otc, Pancoast tumor), stroke, herpes zoster infection, and trauma. Cavernous sinus syndrome presents with headache, ipsilateral eye findings, and sensory loss in the distribution of cranial nerve V—-ophthalmic branch. Transverse myelitis is a postviral or toxic inflammation of the spinal cord that results in sensory loss and paresis. An isolated spinous process fracture typically occurs in the setting of trauma and is considered a stable vertebral fracture. This patient presents with (vertigo) and (atypical arm pain with exercise), symptoms consistent with This phenomenon occurs in patients with subclavian artery occlusion or steno- sis proximal to the vertebral artery branch, which causes retrograde blood flow in the vertebral artery with ipsilateral arm exercise. Collateral arteries arising from the subclavian artery distal to the obstruction deliver blood to the arm. During arm exercise these vessels dilate and siphon blood from the head, neck, and shoulder to increase perfusion of ischemic arm muscles. This results in temporary reversal of blood flow in the vertebral artery leading to vertebrobasilar insufficiency and symptoms of vertigo, dizziness, syn- cope, dysarthria, and diplopia.

Ammonia is present in many household cleaners, as a cooling agent in refrigerator units, and as a fertilizer owing to its high nitrogen content and may act differently depending in what form it is in. For example, it may freeze skin on contact or affect breathing because of its vapors. Formic acid is a caustic organic acid used in many industries that causes a coagulation necrosis. Treatment for exposure to all of these chemicals includes copious irrigation and observation for systemic side effects. The reported incidence of infection from these bites may be as high as 30% to 50%, with many patients presenting only after an infection has incurred. It is important to note that cat bites have a higher infection rate compared to dog bites, given the typical puncture wound that inoculates bacteria down the track deep into tissue and becomes enclosed. Patients need to be followed closely as these infections may seed deep into joints and tissue requiring debridement. Antibiotic topicals, such as bacitracin, would be inappropriate given the high virulence of this organism. In the adult, each anterior or posterior sur- face of the upper extremity and head are equal to 4. More percentage is dedicated to the head given their larger head-to-body ratios (7% in children and 9% in infants). The Prophylactic antibiotics are not warranted in these cases, given the chance of increased future resistance rates. For areas of greater involvement and inhalation burns, fluid resuscitation may patients with a history of altitude illness as prophylaxis. It works to decrease the formation of bicarbonate by inhibiting carbonic anhydrase. It also decreases bicarbonate absorption in the kidney, causing a metabolic acidosis, which stimulates hyperventilation. This compensatory mechanism is turned off when the pH is close to the physiologic range of 7. It’s this hyperventilation that counters the altitude-induced hypoxemia, thereby relieving symptoms. Dexamethasone works to decrease vasogenic edema and decrease intracranial pressure. Nifedipine works by decreasing pulmonary artery pres- sure in high-altitude pulmonary edema as does the diuresis resulting from furosemide. Morphine is thought to reduce pulmonary blood flow and decrease hydrostatic forces in pulmonary edema. These injuries may inflict fractures, cardiovascular collapse, burns, blunt abdominal injuries, and neurologic damage. Although 50 to 300 people die because of lightning strikes each year in the United States, most injuries sustained are not lethal.
Common allergens include pollen buy discount naltrexone 50mg line, animal dander generic naltrexone 50 mg on-line, dust mites order naltrexone 50 mg amex, smoke, and chemicals, such as dyes, perfumes, and preservatives in food. Having a respiratory infection, exercise, stress, and expo- sure to cold air can also trigger an attack. While medication may be neces- sary, there are also lifestyle approaches and nutritional supplements that can help reduce the severity and frequency of attacks. You may have only occasional asthma attacks that are mild and short-lived and between episodes you may feel normal and have no problems in breathing. An allergy is a reaction to a substance that is normally harmless, such as reacting to ﬂower pollen or house dust. Being exposed to an allergen may cause irrita- tion and swelling in various areas of the body, such as the nose, eyes, lungs, and skin. Allergens can make asthma symptoms worse by increasing the inﬂammation in the airways and making them more sensitive. The best way to ﬁnd out if you are allergic to something is to be tested by an allergist. Quick-acting brochodilators, also called “rescue” medications, include salbutamol (Ventolin) and ipratropium (Atrovent). These drugs can stop an asthma attack and relieve symptoms of coughing, wheezing, chest tightness, and shortness of breath. These medications should be carried with you at all times so that you have them handy when you feel an attack coming on. There are also long-acting bronchodila- tors, such as salmeterol (Serevent Diskus), which are used to control moderate and severe asthma and to prevent nighttime symptoms. Anti-inﬂammatory medications (steroids), which help relieve the swelling of tis- sue, are used for those with moderate to severe asthma. They are available in tablets (prednisone) and inhalers such as ﬂuticasone (Flovent), budesonide (Pulmicort), and beclomethasone (Beclovent). They may take a few hours or even days to work, so they are not to be used as rescue medications. Long-term use of these drugs can cause serious side effects, including cataracts, osteoporosis, muscle weakness, decreased resistance to infection, and thinning of the skin. The inhalers are safer than oral ste- roids, but they may still increase risk of osteoporosis when taken over the long term and can cause thrush and coughing. Using a spacer device (Aerochamber) will help improve delivery of the medication to your lungs and can reduce the risk of thrush and mouth irritation. Other drugs used to reduce inﬂammation include montelukast (Singulair), nedocromil (Tilade), and cromolyn (Intal). Those with exercise-induced asthma may need only a bronchodilator when exer- cising. For asthma triggered by allergies, injections to desensitize you to the allergen can be given. There is also a new drug in Canada called omalizumab (Xolair), which blocks allergy-causing antibodies. Foods to avoid: • Dairy products can increase mucus formation, which can affect breathing. Lifestyle Suggestions • Identify and avoid indoor and outdoor allergens and irritants. Control pet dander by having your pets groomed regularly and vacuuming your carpets and furniture. During cold months, exercise indoors or wear a face mask to warm the air you breathe. Be aware that if your asthma is not under control, exercise can trigger an attack.
