The simplest method for calculating a DV01 is to average the absolute price changes of a particular treasury security for a 1-basispoint (bp) increase and decrease in yield to maturity. In a simple example we use the 30 year bond trading at 122 08 or $122,250.00 which is a 6 percent coupon bond with 15 years remaining until maturity. This is roughly the CTD bond at this time with the price based on the current U.S. Treasury bond futures contract. A change in price of $100 will equate to 1 bp up or down in yield. To get the absolute DV01, you would need to do 1bp up and 1bp down and divide the total by 2 to have a true DV01. Let s assume, for example purposes, that this bond represents the xed income risk to interest rates in your portfolio. In reality you would need to nd the DV01 for each income asset and nd the appropriate maturity issue or ratio of cheapest to deliver (CTD) treasury issues to account for the maturity differential between your assets and the CTD futures. As yield rises 1 bp, the risk to the price of the asset is $100. If you had $1 million in these securities each basis point would be $1,000 loss of value. So a standard interestrate hike in short-term rates of 25 basis points that is carried through into the long maturity market could affect the portfolio value by $25,000. Long-term interest rates rising by 2.00 points could cost this bond holder $200,000. When current Fed rates are at 25 basis points to zero and long-term mortgage rates are in the 4 percent range, the risk of a 2.00 point hike is substantial.

Signals: start the whole thing. They re what the target cell senses. Receptors: sense the signal and are activated. Sensing the signal causes a change in the structure of the receptor. This structural change activates the pathway. Transducers: receive the signal and then pass it on in a different form. They can amplify the signal or integrate signals from multiple pathways. Most components of signal transduction pathways can be considered transducers. Second messengers: small molecules that are released in the cell in response to a signal. They can activate many other downstream components. Amplifiers: increase the strength of the signal. They turn one molecule of original signal into many, many molecules of second messengers or secondary signals. Integrators: allow multiple signals to converge on a single response. Effectors: the final step of the signaling pathway. Their activation results in the effect. Sometimes signals can activate multiple pathways and have multiple effects. Inhibitors: turn off signaling pathways. Activating an inhibitor has the same effect as inactivating the signaling event.

same pattern of weakness. Davidenkow, who wrote extensively on this subject, described a form of familial scapuloperoneal weakness and atrophy associated with are exia and distal sensory loss (a spinal-neuronopathic form), and others have con rmed these ndings (see discussions of Thomas et al and of Munsat and Serratrice). Nevertheless, Thomas and colleagues (1975) rmly established the existence of a purely myopathic form. The onset of symptoms in their 6 patients was in early or middle adult life, with dif culty in walking due to bilateral foot drop; symptoms referable to scapulohumeral involvement came later. Progression was slow and none of the patients became severely incapacitated. Autosomal dominant inheritance seemed likely. More recently, Wilhelmsen and associates have described a large family with autosomal dominant scapuloperoneal myopathy (14 affected persons in a 44-member pedigree). Onset was in early adult life with dif culty in walking and climbing stairs, due to foot drop, followed by weakness of the proximal arm muscles. In 3 individuals from this family, the disease was relentlessly progressive, but in the others it was relatively benign. In addition to the nonspeci c histologic features of muscular dystrophy, some bers contained eosinophilic hyaline inclusions and rimmed vacuoles. Linkage analysis has localized the gene to chromosome 12, proving that it is not simply an allelic variant of facioscapulohumeral or one of the other types of muscular dystrophy. It is now clear that there is some molecular heterogeneity in these cases, as other pedigrees link to chromosome 3.
