If a researcher were interested in measur ing attitudes toward a class in research methods order 3 ml lumigan with visa medicine you can give cats, he or she could develop a set of summary statements and then ask the participants to rate their at titudes along a bipolar continuum 3ml lumigan visa medicine 5113 v. One statement might look like this: On a scale of 1 to 5 order lumigan cheap medications images, please rate the extent to which you enjoy the research-methods class. The use of global ratings is also common when asking participants to rate emotional states, symptoms, and levels of distress. The strength of global ratings is that they can be adapted for a wide va riety of topics and questions. Despite this, researchers should be aware that such a rating is only a global measure of a construct and might not capture its complexity or more subtle nu ances. For example, the previous example may tell us how much someone enjoys a certain research-method class, but it will not tell us why the per son either loves it or hates it. This ap proach relies on the direct observation of the construct of interest, which is often some type of behavior. The use of this approach is widespread in a variety of research, educational, and treatment settings. This ap proach is an efﬁcient way to collect data when the researcher is interested in studying and quantifying some type of behavior. For example, a re searcher might be interested in studying cooperative behavior of young children in a classroom setting. After operationalizing “cooperative be havior” as sharing toys, the researcher develops a system for quantifying the behavior. In this case, it might be as simple as sitting unobtrusively in a corner of the classroom, observing the behavior of the children, and counting the number of times that they engage in cooperative behavior. Alternatively, if we were interested in studying levels of boredom in a research-methods class, we could simply count the number of yawns or number of times that someone nods off. As with other forms of data collection, the process of quantifying ob servations should be standardized. The behavior in question must be ac curately operationalized and everyone involved in the data collection should be trained to ensure accuracy of observation. Proper operational ization of the variable and adequate training should help ensure adequate validity and interrater reliability. Videotaping and multiple raters are fre quently used to conﬁrm the accuracy of the observations. The use of ob servational methods usually produces frequency counts of a particular behavior or behaviors. It often involves measuring the physiological responses of participants to any number of potential stimuli. The most common examples of re sponses include heart rate, respiration, blood pressure, and galvanic skin response. Consider a study investigating levels of anxi Multiple Measurement ety in response to a certain aver Strategies sive stimulus.

Note that in this form the sulfhydryl groups (yellow balls) are not close to each other; therefore buy discount lumigan 3 ml online symptoms restless leg syndrome, a ma jor conformational change must occur to permit their combination into disulﬁdes order lumigan us symptoms menopause. This conformational eﬀect is thought to signal the change of redox state to other proteins cheap 3 ml lumigan with amex symptoms mononucleosis. Thioredoxins, glutaredoxins, and protein-disulﬁde isomerases all reduce protein disulﬁdes, in diﬀerent contexts as indicated. This slide illustrates •– how several antioxidant enzymes cooperate to prevent this. The latter can be further disproportionated to water and O2 by catalase; however, this enzyme is not very abundant in mitochondria. Reaction with H2O2 converts Prx to a disulﬁde, which is then reduced again by thioredoxin (Trx) and thioredoxin reductase. Interestingly, the active site of a glutathione peroxidase molecule contains a selenocysteine residue. The selenide group in its side chain – – (R – SeH), in its anionic form (R – Se ), reacts similarly to a cysteine thiolate (R – S ) but more rapidly. In the course of the reaction, the enzyme becomes transiently bound to glutathione (in the following form: R – Se – S – G). It is then reduced and released again by a second equivalent of glutathione; the reaction mechanism is analogous to that shown in slide 18. In particular, glutathione can reduce ascorbate, which in turn can regenerate urate and α-tocopherol. It can be regenerated from dehydroascorbate using glutathione; this reaction is carried out by glutaredoxin. Since free glutathione and glutaredoxin levels are much higher inside the cell than outside, this pathway only occurs intracellularly. An alternate pathway for reducing extracellular dehydroascorbate that does not require uptake into the cell is outlined in slide 18. Dehydroascorbate that is not reduced may undergo non-enzymatic hydrolysis to 2,3-diketogulonate. However, animals other than primates can produce ascorbate from glucose via d-glucuronate and l-gulonate and thus do not depend on the diet for ascorbate replenishment. Overall, it appears that pathways for reductive regeneration of radical scavengers are quite promiscuous, and this may account for the similarly promiscuous reductive metabolism of drugs. To determine the energy of ascorbyl disproportionation, we simply invert the ﬁrst reaction and accordingly the sign of its potential. For the sum of both reactions, we obtain a strongly positive reaction potential, which equals a strongly negative free energy. Thus, even when re ducing power for converting ascorbyl back to ascorbate is not immediately available, the equilibrium of disproportionation will keep the free concentration of ascorbyl very low. If we also consider that ascorbyl is stabilized by resonance and therefore less reactive than most other radicals, it becomes clear that Nature made a very smart choice by picking ascorbic acid as its favorite radical scavenger. It has indeed been shown that urate’s antioxidant eﬀectiveness resembles that of ascorbate [156, 185, 186]. Since in primates the plasma concen tration of urate exceeds that of ascorbate, it is fair to consider urate the major extracellular antioxidant.
