Stigma In the Chinese worldview, schizophrenic patients’ occasional disruption of social order and their failure to act in ways that promote social harmony are considered serious transgressions

of social norms. Given the public’s fear of the mentally ill and of their potentially disruptive effects, the community approach to the mentally ill is primarily focused on control and only secondarily on treatment. A 1999 study about attitudes Inhibitors,research,lifescience,medical toward the mentally ill in Beijing29 found that over 60% of 254 randomly selected community members believed that persons with severe mental illnesses should not be allowed to marry or have children, and about 40% believed that the mentally ill should not be allowed to live in the community, return to work, or attend university. These

beliefs make it extremely difficult for persons who suffer from a serious mental illness to Inhibitors,research,lifescience,medical obtain a job or get married, and so most patients remain dependent on family members for their entire life. Thus, it is not surprising that family members often delay necessary treatment for fear of being stigmatized and frequently go to extreme lengths to prevent neighbors and other acquaintances from discovering the family secret. In most cases, the secret eventually comes out, resulting Inhibitors,research,lifescience,medical in severe negative consequences for the individual and the family. Combining data from a number of studies undertaken in several locations around the country from 1990 to 1998, 84% (712/847)

Inhibitors,research,lifescience,medical of family respondents of schizophrenic patients reported that social stigma affected the daily lives of their ill family member and 51% (434/847) reported that social stigma affected the daily lives of healthy family members. In a Beijing study29 over 40% of the 211 schizophrenic patients interviewed felt that their work unit discriminated against them and that their neighbors Inhibitors,research,lifescience,medical looked down on them and their family; 28% reported moving their homes to avoid stigma. Family burden The economic almost and emotional burden of caring for a schizophrenic family member in China is quite high. Among family members of 456 admitted schizophrenic patients from around the country,22 65% reported that the illness had a severe effect on healthy family members’ emotional health over the prior 3 months, 46% reported a severe effect on family finances, and 39% reported a severe effect on healthy family members’ work. Assessment of family members with a revised Chinese version of the Camberwell Family Interview30,31 found that between 40% and 50% of coresident family members of schizophrenic patients have high expressed emotion at the time of the patient’s admission. (The ability of this measure to predict subsequent ATPase inhibitor relapse in China has not yet been fully assessed.

12 Iran does not have as high a prevalence rate of IBDs as do western countries; however, due to changes in people’s lifestyle and industrialization in tandem with other Asian countries, we may expect a rising trend in our region.13 Indeed,

a proliferation in the number of published articles on IBDs during the last decade is evidence of the vigorous elevation of concerns over IBDs in Iran: where there were only 3 articles on IBDs before the year 2000 in Iran, the period between 2000 and 2012 saw the figure soar to 26 articles. A study in South Korea showed that the prevalence of UC was 7.57 in 100,000 individuals in 1997, whereas an increase of 30.87 patients in 100,000 individuals was noted in 2005.14 Inhibitors,research,lifescience,medical This rising trend is also visible in Japan. The prevalence of CD, which was 2.9 in 100,000 people in Japan in 1986, reached 13.5 in 1998.15 The prevalence of IBDs in the Middle East countries such as Lebanon16 and Israel17 also indicates a growing trend. The prevalence of UC in Kuwait in 1999 Inhibitors,research,lifescience,medical was 41.7 for 100,000 individuals.18 The annual incidence rates of UC and CD were 3.08 and 1.34 cases per 100,000 person-years in South Korea,14 1.95 and 0.51 in Japan,19 4.1

and 1.4 in Lebanon,17 and 5.04 and Inhibitors,research,lifescience,medical 5.0 cases per 100,000 person-years in Kibbutz, Israel17 respectively. A population-based study in Punjab, North India, demonstrated that the prevalence of UC was 44.3 in 100,000 persons and the incidence of this disease was 6.02 per 100,000 person-years.20 Demographic Variables: Gender Gender assessment on IBDs in Iran Inhibitors,research,lifescience,medical illustrates male/female (M/F) ratios for UC of 1.6/1,21 0.78/1.0,12 0.7/1.0,22 0.8/1.0,23 and 1.2/1.1,24 and M/F ratios for CD of 1.4/1.0,21 1.18/1.0,12 0.9/1.0,22 1.2/.8,24 and 1.3/1.0.23 It seems that female predominance in UC and male predominance in CD are the major demographic patterns of IBDs in Iran. The male predominance has been

Inhibitors,research,lifescience,medical AG-014699 in vivo reported for CD in China,25 Japan,15 and Korea.14 The M/F ratio for UC is nearly equal in Korea and Japan26 and the F/M ratio is 1.33 in Riyadh, Saudi Arabia.27 Age The mean age at diagnosis of IBDs in Iranian patients is identical to that of other Asian countries; while in four different studies, it was 33.6 for UC12,23,28 and 32.3 for CD.12,23 One peak age of onset has been reported in the second decade of life and the second peak Bay 11-7085 has not been seen in Iran.12,22,23,29 Based on one report, Asian countries have a peak age of onset at 20-39 years of age for both diseases and the second peak has not been seen in most of them; whereas a small second peak has been reported by the same author in another study.14 The trend of the second peak has also been observed in a study conducted in the Chinese population of Hong Kong.25 Urban Versus Rural Distribution This factor has been assessed in three studies in Iran. The mean percentage of UC in urban areas was reported to be 73.8%, whereas this mean percentage for CD was 86%23,29 which clearly denotes a higher prevalence rate in city dwellers.

Within the two parts, ROIs were PF-4708671 order defined as the 125 voxels (5 × 5 × 5) around the most active voxel (Fig. 2). Due to the proximity of the primary motor and the primary sensory cortex, we cannot exclude that some of the measured fMRI activity originated from the primary sensory cortex. Hence, we refer to this region as primary sensorimotor cortex. Figure 2 Subdivision of the primary sensorimotor cortex hand area in the more medial inferior and posterior (green) and more lateral superior and anterior (blue) part of all subjects.

Left picture side corresponds to right hemisphere, Inhibitors,research,lifescience,medical right picture side to left … Coding was as follows: for right-handers, right hand was coded as dominant hand and left hand was coded as nondominant hand, whereas Inhibitors,research,lifescience,medical left hemisphere was coded as dominant hemisphere and right hemisphere was coded as nondominant hemisphere. For left-handers it was the other way around, left hand was coded as dominant hand and right hand was coded as nondominant hand, whereas right hemisphere was coded as dominant hemisphere and left hemisphere was

coded as nondominant Inhibitors,research,lifescience,medical hemisphere. For each subject, the time course of the BOLD signal of the 11 experimental conditions was extracted separately for the four ROIs (dominant and nondominant hand area divided in two subregions each). The time courses were averaged over the four blocks of each experimental condition and over all voxels of the respective ROI. The mean signal of the 2-sec preceding the finger movements was assigned as baseline and the percentage Inhibitors,research,lifescience,medical of signal change to baseline was extracted and averaged from second six to 18 of every block for each experimental condition and ROI separately. Data were analyzed separately for both handedness groups with four mixed models, namely one for moving finger of the dominant hand, Inhibitors,research,lifescience,medical one for the nondominant hand, one for both hands under undivided concentration, and one for both

hands under divided concentration. In all analyses of the functional data, the random effect was subject and the fixed effects were hemisphere, subregion, attention level, and the interaction terms between the fixed effects. The fixed effects of the full models were tested with F-tests. The post hoc tests comparing two subconditions only were done with t-tests. In the case of missing data from an experimental condition (due (-)-p-Bromotetramisole Oxalate to technical issues), we excluded subjects from the subanalysis (right-handers nondominant hand, n = 1; both hand undivided attention, n = 2; left-handers both hands undivided attention, n = 2). Mixed-model calculations for the ROI analyses were performed with the nlme package (Pinheiro et al. 2012) in R 2.14.0 (R Development Core Team 2011). Reported significance levels were corrected for eight independent tests, to correct for the four models calculated in both handedness groups.

49 When examining data for Selleck Foretinib individual patients, it is important to separate random, nonsystcmatic variability from variability caused by the drug. In order to be able to interpret any QTc change from baseline, it. is mandatory to know the within-subject variability over the time of ECG. This may be studied by looking at, QTc changes observed in placebo-treated subjects. Pratt, et al48 showed that 50% (14 out. of 28) of healthy male subjects had Inhibitors,research,lifescience,medical at least. 1 of the 40 ECGs recorded during the 6-day period of the study with a QTc

value above a threshold of 440 ms. In the same study, 71 % (20 out. of 28) of cardiac patients had at least one QTc value above 440 ms when receiving placebo treatment.48 The average QTc fluctuation or variability over 24 hours in normal men, measured as the Inhibitors,research,lifescience,medical difference between

the shortest and the longest. QTc value recorded, was 56±15 ms48 or 59±12 ms.50 Individual healthy male subjects (n=20) had a wide range of QTc fluctuations over 24 hours which averaged 76±19 ms (range: 35-108 ms) when QTc was measured by Holter recording.51 Among these subjects, the QTc interval increased to over 440 ms in 11 of the 20 subjects (55%) during the 24-hour Inhibitors,research,lifescience,medical monitoring period. It even exceeded 500 ms in 1 of the 20 subjects.51 When looking at the fluctuations observed during the first 12 hours of dosing of healthy young subjects hospitalized in a clinical pharmacology unit, the mean fluctuation was 31 ms in 1.18 male and female subjects52 and 31±14 ms Inhibitors,research,lifescience,medical (range: 4-63 ms) for 82 male subjects (Patat, unpublished data). Finally, the average maximum increase

from baseline observed postdose in placebo-treated subjects was 17 ms over 8 hours postdose52 and 14.0±12.7 ms over 12 hours postdose (Patat, unpublished data). Patients with cardiac disease show a greater spontaneous variation and a somewhat, exaggerated QT response to drug effect.48 Based on these data in healthy subjects, it. may be concluded that, individual changes of QTc Inhibitors,research,lifescience,medical of less than 40 ms reflect, normal biological and methodological variability and are unlikely to indicate drug effects, that individual changes between 40 and 60 ms are probably beyond normal biological and methodological variability and indicate possible proarrhythmogenic drug effects, and that individual changes above 60 ms exceed the normal biological and methodological variability, about and indicate proarrhythmogenic drug effects. Current guidelines place emphasis on two types of flags: raw QTc and delta values (change from baseline). There is little agreement among the scientific community on what constitutes a prolonged QTc interval. The Food and Drug Administration (FDA) in the United States has not issued any sort of formal guidance on the matter, but the EMEA has issued a guidance document.

To obtain a higher degree, several members of the dynasty, like Ephraim, studied in Bordeaux—and did so with distinction—but in Ephraim’s case this was only late in life, namely at the age of 43 (according to the Hebrew calendar).The

reason for this delayed graduation is not clear. It is likely that he practiced as a general physician in Amsterdam but needed the doctorate for a higher position. The Bordeaux University Archives describe in detail the ceremony where Ephraim was awarded his doctorate. The three examiners were all descendants of converted Jews, so-called Marranos, whose families had lived in southern France for generations. The patron of the thesis, Professor Lopes (an old friend of Ephraim’s father), accorded him the title of “Magnus Inhibitors,research,lifescience,medical in Medicina.” From there, Ephraim joined the some 400 Portuguese Inhibitors,research,lifescience,medical Jews in Amsterdam. Apart from practicing medicine, he was also a scholar of the Bible. Indeed, together with Ben Manasseh and Jonah Abravanel, Ephraim published poetry,

translated into Spanish the Psalms of David, and in 1650 published Pene Rabbah, an index to the biblical passages found in the Midrash Rabbah. He also founded the charitable organization “Torah Or” in Amsterdam. He must have been appreciated as a physician as he attended, together with his father Joseph, the Regent of the Netherlands, the Prince of Orange. Rembrandt depicted his physician Ephraim on two occasions. It is not known if Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical these portraits were commissioned; possibly they were Selleckchem EVP4593 honoraria for medical services provided by Dr Bueno. There is firstly an etching of 1647, Dr Bueno Descending the Stairs, where he is shown in well-to-do attire

with the obvious ring on his index finger representing the insignia of the medical community (Figure 1).1 Prints of this etching are found today in museums around the world, such as the Metropolitan Museum in New York and the National Gallery of Victoria in Melbourne, Australia, etc. Figure 1. Rembrandt’s Inhibitors,research,lifescience,medical etching of Dr Ephraim Bueno, 1647 (in public domain). Rembrandt’s second image of his private physician was an oil portrait, today in the Rijksmuseum, Amsterdam.9 This oil painting has an interesting provenance: originally it was in the possession of the Six family and remained so for over two centuries. Then, in the early twentieth century, it was bought by the Jewish banker Fritz Mannheimer. The image of this Jewish physician was then purchased on behalf of Hitler’s intended “Fuehrer Museum” in Linz, Austria (which never eventuated), from and it was transferred to the Central Collection Point in Munich in 1942. After the fall of the Third Reich the painting was returned to the Netherlands in 1948 and was finally transferred to the Amsterdam Rijksmuseum in 1960. In 1656 Ephraim, as an old man, was also etched by another famous artist, Jan Lievens (Figure 2). The figure is seated, wearing a Kippah, and at the bottom of the print is written: “Dr Ephraim Bonus, Medicus Hebraeus … Magnus in Medicis.

5 While the boy presented with persistent seizure as a sign of neurotoxicity, constipation was the common symptom between our case and the previous report. Mantadakis and colleagues,6 reported a young adult, who received Vincristine and Posaconazole as prophylaxis. The

authors also reported severe peripheral neuropathy as a side effect of such combined treatment. The unique features of Posaconazole BYL719 solubility dmso toxicity in our patient were jaw pain and ultrasonographic signs of pancreatitis. Pancreatitis has been reported as a drug Inhibitors,research,lifescience,medical reaction in the official drug information of Posaconazole; nevertheless, it has been reported in consequence of the other azole member, Itraconazole.7 Another interesting point about our patient was the occurrence of these symptoms just after he had received one single dose of Vincristine; this has not been reported in the previous few reports. Peripheral neuropathy manifesting as constipation and abdominal pain can present in patients receiving combined Vincristine and Posaconazole. Early diagnosis and conservative management are the only Inhibitors,research,lifescience,medical required managements needed in patients with ALL receiving both drugs. Not only should clinicians administering chemotherapy take heed of the interaction profile of

Posaconazole with Vincristine but they should also closely monitor their patients for possible neurotoxicity. Conflict of Interest: None declared.
A Richter’s hernia is a type Inhibitors,research,lifescience,medical of hernia in which only a part of the circumference of the bowel is entrapped and strangulated in the hernial orifice, leading to ischemia, gangrene, and perforation of the hollow viscus.1 The portion

of the bowel which is usually involved is the distal ileum; however, any part of the intestinal tract, from the stomach to Inhibitors,research,lifescience,medical the colon, may become incarcerated. A Richter’s hernia occurs when the size of the hernial orifice is large enough to entrap the partial circumference of the bowel Inhibitors,research,lifescience,medical wall, but it should be small enough to prevent protrusion of a loop of the intestine, and there should be a firm margin of the hernial ring. A Richter’s hernia progresses more rapidly to gangrene due to compromised blood supply. This may be explained by the firm constricting ring that exerts direct pressure on the bowel wall. When less than two thirds of the circumference of the bowel wall is involved, the signs and symptoms of intestinal obstruction are absent. This Rutecarpine leads to late diagnosis or even misdiagnosis, and thus it allows bowel necrosis to develop. The common sites of Richter’s hernias are the femoral ring and at trocar sites after laparoscopic procedures.2 The trocar site is closed routinely nowadays to prevent the development of hernia. Unusual occurrences are at the insertion site of the drainage tube following open abdominal surgery, as a Spigelian’s hernia, through the sacral foramen. A spontaneous fecal fistula is an extremely rare complication in a long standing abdominal wall hernia.

As shown in Figure 2(a), dextran transport was increased approximately twofold in the cell cultures incubated with the AC formulation. Figure 2 Effects of the AC formulation on endothelial paracellular flux. (a) Increase in dextran permeation induced by the AC formulation. One hour after the addition of oligodeoxynucleotides (ODN), atelocollagen (AC), or the AC formulation (AC + ODN) to the inner … Next, the paracellular transport of atelocollagen was analyzed and compared with those of BSA and dextran. Inhibitors,research,lifescience,medical Neither BSA nor dextran affected the TER value of the cells. Only very small amounts of BSA and dextran penetrated the cell sheet during

the 2-hour study period; on the other hand, much more atelocollagen passed through, even though the molecular weight of atelocollagen is 4-5 times higher than those of BSA and dextran (Figure 2(b)). An examination using BMVEC [27] was performed to determine whether the effect of the AC formulation was specific to HMVEC. As a result, we found that Inhibitors,research,lifescience,medical the TER value of the BMVEC was also reduced by the AC formulation (and only the AC formulation), as shown in Figure 3. BMVEC forms the this website blood-brain barrier (BBB), where intercellular sealing function is strictly maintained. These results showed that the AC formulation is able to affect the paracellular flux of endothelial barriers. Figure 3 Effects of the AC formulation on the TER of BMVEC. The bar represents TER as a percentage compared Inhibitors,research,lifescience,medical to the value observed at

the start of the experiment. TER Inhibitors,research,lifescience,medical was determined at 1 and 2 hours after treatment with ODN alone (ODN), atelocollagen alone (atelocollagen), … 3.2. Effects on Cell Morphology It is well known that increased endothelial permeability is associated with impaired intercellular contact [32–35]. We carried out an immunohistochemical analysis of the cells treated with the AC formulation to clarify how their intercellular sealing was affected. As shown in Figure 4(a), treatment with the AC formulation markedly reduced the degree of intercellular contact,

as Inhibitors,research,lifescience,medical shown by intercellular gap formation, actin stress fiber formation, cellular contraction, and a lack of VE-cadherin. Adequate expression of claudin-5, one of the key components of the endothelial barrier, was noted at the cell periphery. However, ZO-1 protein expression was absent from the intercellular gaps. On the contrary, Cell press Western blotting revealed that treatment with the AC formulation did not affect the expression of these proteins (Figure 4(b)). Although the TER value remained low as long as the AC formulation was present in the culture medium, the treatment did not cause toxicity. The cells survived well for at least 24hrs, and both the TER and morphology of the cells could be recovered by removing the formulation (data not shown). No such morphological changes were induced by treatment with ODN or atelocollagen alone (Figure 4(a)). Figure 4 Effects of atelocollagen combined with ODN on intercellular formation.

This may result from a decreased protein expression, possibly due to the phosphorylation, and subsequent inactivation of an element of the transcriptional machinery. Alternatively, it may result from the PKG-induced degradation of the proteins. It is also possible that phosphorylation by PKG

of the proteins or of Inhibitors,research,lifescience,medical some partner proteins may have induced the formation of alternate complexes that prevented accessibility of MeCP2 and HDAC2 to their respective antibodies. This latter possibility is particularly attractive as both proteins were similarly regulated. The effect on both proteins was abolished by the injection of the selective PKG inhibitor, KT5823, confirming that the effect was due to PKG-dependent phosphorylation. The effect on MeCP2 expression was greatly potentiated in the three structures examined by the addition and subsequent activation of exogenous overexpressed PKG. Surprisingly, the latter effect was not observed when HDAC2 expression was measured. It is noteworthy that other HDACs, such as HDAC5 or Inhibitors,research,lifescience,medical HDAC11, which belong

to different classes of histone deacetylases that are also regulated by cocaine (Host et al. 2011), were not modulated by PKG (data not shown), Inhibitors,research,lifescience,medical suggesting a unique role of HDAC2 in this process. In contrast, injection of the PKG vector or Br-cG into the VTA failed to alter MeCP2 or HDAC2 levels in any of the brain sites. The data probably underscore a differential action of PKG at the pre- and postsynaptic levels. Effectively, the observation that only intra-CPu infusions produced the effect probably denotes that it results Inhibitors,research,lifescience,medical from a PKG-modified signal transduction pathway taking place in neurons postsynaptic from the dopaminergic neuron. Indeed, in an Inhibitors,research,lifescience,medical electron microscopy study, we showed that PKG was localized mainly in postsynaptic sites (data not shown). These findings are check details consistent with our previous results that

also failed to find an effect of intra-VTA infusions of Br-cG on cocaine-induced egr-1 expression in the CPu (Jouvert et al. 2004). When the PKG vector was injected into the CPu, overexpression of the kinase was found primarily Oxymatrine in GABAergic medium-spiny neurons (Jouvert et al. 2004). Activation of the cGMP pathway in these neurons probably modulates GABA release in many projection areas and therefore disrupts the striato-nigro-thalamic loop. Modulation of neurotransmitter release by cGMP has been demonstrated in many systems; cGMP activators like natriuretic peptides inhibit various secretory responses such as aldosterone and catecholamines (Samson et al. 1993; Babinski et al. 1995), whereas endogenous NO modulates the release of several neurotransmitters, including catecholamines, excitatory and inhibitory amino acids, and serotonin (Guevara-Guzman et al. 1994; Prast and Philippu 2001).

These studies highlight the importance of postmortem study data and their conclusions. They guide our clinical formulations, and thus our experimental and therapeutic approaches. Finally, studies with DJ-1 are in very early stages. Its distribution has been analyzed in postmortem brain of control and PD subjects in two recent studies. DJ-1

does not colocalize with LBs, but with tau inclusions; it is mainly expressed by astrocytes; and it appears to be sensitive to oxidative stress:11,42 At present, a functional interpretation of these data is lacking. The role of LBs in DA cell death There remains much debate over whether LBs are neuroprotective, constitute Inhibitors,research,lifescience,medical an age-related epiphenomenon, or are cytotoxic; Inhibitors,research,lifescience,medical postmortem end points may supply some answers. Recently, Conway et al43,44 suggested that, accelerated formation of nonfibrillar α-synuclein oligomers is the critical process in PD pathogenesis, ie, LB formation is neuroprotective by sequestering toxic protein species. Once this issue is resolved, Inhibitors,research,lifescience,medical drug therapy can be aimed at promoting the healthy process. Two observations from pathological examination of human brain contribute to this dialogue: SNpc DA neurons containing LB appear to be “healthier” than neighboring neurons,45 whereas

the nigral DA neurons undergoing apoptotic-like cell death do not contain somal LBs. Tompkins and Hill45 suggested that the majority of SNpc neurons die before or without forming LBs and that SNpc neurons that survive the initial pathological insult suffer damage that leads to LB formation. It is not uncommon to observe “incidental” LBs at autopsy of aged asymptomatic individuals. An alternative explanation Inhibitors,research,lifescience,medical for this finding Inhibitors,research,lifescience,medical is

that these individuals have not lived long enough to develop a parkinsonian phenotype. Also, if LBs were protective, one might speculate that controls should have more LBs than PD patients, which is clearly not the case. Alternatively, LBs may occur as an epiphenomenon of the primary pathology and have little or no effect on neuronal viability. In contrast to the observations by Tompkins and Hill,45 Resveratrol Gibb and I .ees46 reported that SNpc neurons with and without somal LBs generally appear to be similarly affected by the disease process. Moreover, cell size and nucleolar size do not differ between LB-positive and LB-negative SNpc neurons.47 Also, dendritic morphological abnormalities found in parkinsonian SNpc arc similar in LB- and non-LB-containing neurons.48 Finally, neurofilament mRNA levels also show a similar level of reduction for both LB- and non-LB-containing neurons.49 We favor the PD184352 cell line hypothesis that the presence of LBs is an indicator of neuronal distress, although it is impossible to deduce from postmortem work whether I ,Bs are, as such, neurotoxic.

Platelet GDC-0449 clinical trial aggregation measurement by PFA is the most sensitive laboratory test in these situations, and should be considered if hemostasis tests are

The experience of traumatic life events is an important factor in the development of a number of clinical conditions, ranging from anxiety disorders such as post-traumatic stress disorder (PTSD) to drug addiction. However, not all individuals who encounter stressful life events develop these disorders, and so there is considerable interest in understanding what makes an individual vulnerable, and what makes an individual Inhibitors,research,lifescience,medical resilient to the deleterious effects of traumatic events.1 Genetic factors doubtlessly play a role, but aspects of the stress experience and complex cognitive Inhibitors,research,lifescience,medical factors regarding how the individual appraises or views that

experience have been argued to be key. In humans, most studies of resilience have included the individual’s perceived self-efficacy,2 perceived ability to cope,3 or actual ability to exert control over the stressor4 as key variables. Furthermore, other factors, such Inhibitors,research,lifescience,medical as religious faith5 and sociopolitical effectiveness,3 have been argued to produce resilience because they induce a sense of control. It is difficult to study variables such as these in animals, yet it is in animals that detailed neurobiological mechanisms can be explored. The stressor controllability paradigm, however, is one of the few that allows isolation of this type of process. Here, animals that receive stressors that are physically identical are compared, with Tryptophan synthase one group having behavioral control over an aspect of the stressor (its termination), and the other group having no control In our version of this paradigm, rats are placed in small boxes with a wheel mounted on the front. The rat’s tail extends from the rear of the box so that electrodes can be directly fixed to the tail For one group of rats (“escape”) each of a series of tailshocks terminate when the rat turns the wheel with its paws. Thus, this group has behavioral control over the termination of each tailshock.
