Assessment of pain severity is specifically sought to guide paramedics’ pain management decisions, which may include strategies designed to mitigate the cause of the pain and to provide relief

from pain that includes efforts to manage the environmental, social and psychological mediators of the perception and expression of pain[10]. In addition, the assessment and evaluation of the patient’s pain experience will influence pharmacological interventions aimed at providing relief Inhibitors,research,lifescience,medical from pain. Tools used to elicit a patient report of severity include the Verbal Descriptor Scale (VDS), which requires the patient to rate their pain using adjectives such as “none,” “slight,” “moderate,” “severe,” or “agonizing,” and the Verbal Numeric Rating Scale (VNRS), where the patient assigns a number from 0-10 to quantify their pain, with 0 representing no pain and 10 representing the worst pain imaginable. Both types of scale are recommended for use by paramedics[13]. The Visual Analogue Scale (VAS) has also been used to measure pain severity in adults in the prehospital Inhibitors,research,lifescience,medical setting[14,15].(In

Australia the Victorian Ambulance Service Tasocitinib recommends Inhibitors,research,lifescience,medical the use of the VNRS for the assessment of pain in adults[16], and in the United Kingdom, the clinical practice guidelines developed by the Joint Royal Colleges Ambulance Liaison Committee also recommends the use of the VNRS for scoring pain severity in adult patients[17]. While these scales have been shown to be valid methods of documenting pain severity and changes in severity, their effectiveness depends on the patient’s ability to understand instructions in their use in order to quantify their pain. In addition, self-report of pain severity requires the use of higher cognitive functions and the Inhibitors,research,lifescience,medical ability to use abstract reasoning to associate numbers or a list of adjectives with the severity of pain that an individual may be experiencing. While many

patients can use these scales to indicate the severity Inhibitors,research,lifescience,medical of their pain, in others the ability to communicate their pain experience may be impaired by language difficulties, developmental barriers (developmental disability and pre-verbal children), physiological barriers (for example coma), or cognitive barriers that include diseases such as dementia. These problems can pose special challenges for health professionals seeking to establish the nature and severity of the patient’s Mephenoxalone distress, and this has the potential to result in suboptimal care. Evidence to support this assertion may be found in a recent study involving a large number of nursing home residents (n = 551), which revealed that the incidence of nursing staff records of pain in residents declined as cognitive disability increased[18]. While 34% of patients with no cognitive disability reported pain during the study period, pain prevalence rates of 31%, 24%, and 10% were associated with residents with mild, moderate, and severe cognitive impairment.

47 Global climate change is another environmental factor that affects stone disease rates. For many years the concept of global warming has been debated, and today it is more accepted as a legitimate phenomenon. The general consensus is that average global temperatures have increased.48 In addition, studies have documented the association between increased environmental temperatures and increased kidney stone rates.49 Two recent studies have shown the temporal relationship

between Inhibitors,research,lifescience,medical exposure to high temperatures and the subsequent development of kidney stones. Evans and Costabile50 compared the time of arrival of US soldiers to Kuwait and the time to development of acute renal colic at a US military hospital. Doumerc and colleagues51 recorded temperature Inhibitors,research,lifescience,medical and number of renal colic admissions at a French tertiary care center between 2002 and 2004. These 2 studies reported time delays between exposure to higher temperatures and clinical manifestation of symptoms of 93 days

and 2 months, respectively. Imaging studies to identify stones Inhibitors,research,lifescience,medical prior to exposure to warmer temperatures were not done in these studies. Furthermore, epidemiologic studies in the United States have shown that regions with higher average temperatures have the highest stone rates.2,3,52 The correlation between increased environmental temperature and increased number of stone events supports the conclusion that global warming Inhibitors,research,lifescience,medical has an impact on the development of stones. This has been recently addressed in a study by Brikowski and

associates.49 They examined how global warming alters regional distribution of kidney stones using a modeling technique. They predicted that, based on the effects of global warming, the percentage of people living in areas designated as high risk for kidney stone formation would increase Inhibitors,research,lifescience,medical from 40% in 2000 to 56% by 2050, and up to 70% by 2095. This would result in a significant “climate-related” increase in kidney stone events. Our review demonstrated that there were decreases in stone AZD2014 solubility dmso prevalence among older age groups. This could be due to differences in sampling methods or subjects with stones dying at a younger age. The latter is certainly plausible as kidney stone formation has been linked to a number of medical comorbidities including obesity, diabetes Carnitine palmitoyltransferase II mellitus, hypertension, chronic kidney disease, and cardiovascular problems.5,34,53–56 The body of evidence suggests that the incidence and prevalence of kidney stones is increasing globally. These increases are seen across sex, race, and age. Changes in dietary practices may be a key driving force. In addition, global warming may influence these trends. Overall stone prevalence has doubled in the United States since the 1964 through 1972 time period, although it appears to have stabilized since the early 1980s. Other countries with documented increases in prevalence include Germany, Spain, and Italy.

Initial analysis demonstrated that deep 16S rRNA sequencing enhances the definition of microbial composition and diversity in the vaginal and rectal compartments during pregnancy,21 enhancing “resolution” of composition and diversity differences previously reported by Ravel and others. The number of sequences acquired per specimen is inversely associated with the number of samples multiplexed in a single sequencing reaction. Therefore, our initial objective was to determine the number

of 16S rRNA sequences required per sample for adequate definition of microbial communities in the oral, vaginal, and rectal compartments during pregnancy. Methodology included standard DNA extraction from swab specimens Inhibitors,research,lifescience,medical of the oral cavity, vaginal mucosa, and rectal surface of a cohort of 29 third-trimester

women. Microbial identity was determined by polymerase chain reaction (PCR) amplification and sequencing of the 16S rRNA gene. We acquired 1,000–22,000 sequences per specimen (SPS), and the QIIME pipeline22 was used to assign sequences to the Inhibitors,research,lifescience,medical respective specimen and establish diversity parameters. Diversity in each anatomic site was defined by the number of unique operational taxonomic units (OTU >97% identity) that correlated Inhibitors,research,lifescience,medical with the simulated number of sequences obtained by pyrosequencing (Figure 2). A total of 1.3 million 16S rRNA sequences were sorted into 6,174 OTUs, representing unique genera. In the oral compartment, <2,500 sequences were required to detect the maximum of 220 genera per specimen. Microbial complexity Inhibitors,research,lifescience,medical was limited to 220 distinct genera even at a sequencing depth of 6,500 SPS, defining a diversity ceiling which is similar to the non-pregnant state. As expected, in the rectal compartment, diversity exceeded 650 genera per specimen with consistent linear increases through 6,500 SPS indicating a highly complex microbial environment. Surprisingly, in the vaginal compartment linear increases in the number of genera were also detected

through the collection of >6,500 16S rRNA SPS, similar to the rectal compartment, and >400 genera were identified per specimen in 21/29 Inhibitors,research,lifescience,medical subjects (Figure 1). Microbial composition in the vaginal compartment was complex in the majority of women, NVP-BGJ398 research buy exceeding 600 distinct genera, which requires a sequencing depth of 6,500 SPS in a subset of pregnant women. At Metalloexopeptidase a sequencing depth of 6,500 SPS, this study represents the most extensive characterization of the vaginal microbiome, since no analysis beyond 2,200 SPS is currently available for the vaginal compartment in the pregnant or non-pregnant state. We conclude that in term pregnancy, a high level of microbial composition complexity exists in the vaginal and rectal compartments, which would require deep sequencing of 16S rRNA genes to define composition and diversity.

These investigators further showed that fluoxetine treatment induced the secretion of various signaling molecules such as BDNF, Wnt2, and 15d-PGJ2 from raphe serotonergic neurons and acted cooperatively on the hippocampus, whereas

S100β controlled the locus coeruleus-dependent hippocampal response to fluoxetine.147 These signals relayed the action of fluoxetine on adult hippocampal neurogenesis by downregulating miR-16 in the hippocampus in a region-specific manner. In a complementary fashion, these signaling molecules were found to be increased in the cerebrospinal Inhibitors,research,lifescience,medical fluid of depressed patients upon fluoxetine treatment.147 O’Connor et al149 investigated whether CP-868596 early-life stress in rats induced changes in hippocampal miRNA levels and whether the rapidly acting NMDA receptor antagonist ketamine, electroconvulsive therapy (ECT), or Inhibitors,research,lifescience,medical fluoxetine treatment could reverse these changes. They found that early-life stress affected expression of multiple hippocampal miRNAs. Antidepressant treatments reversed some of these effects including a stress-induced change to miR-451. Ketamine Inhibitors,research,lifescience,medical and ECT possessed the highest number of common targets, suggesting convergence on common pathways. Interestingly, all three treatments possessed miR-598-5p as a common target. This demonstrates that changes to

hippocampal miRNA expression may represent an important component of stress-induced pathology, and antidepressant action may reverse these. In this context, Ryan et al150 examined Inhibitors,research,lifescience,medical ECT-induced BDNF expression and BDNFassociated miRNAs. Following acute or chronic electroconvulsive stimulation (ECS), they found that the level of selective miR-212 was significantly increased in dentate gyrus. miR-2f 2 level was also increased in parallel in whole blood following chronic ECS and

was positively correlated with miR-212 level Inhibitors,research,lifescience,medical in the dentate gyrus, suggesting that miR-212 may be crucial in the mechanism of action of ECT and that it can be used as a biomarker. Using genome-wide expression profiling of human lymphoblastoid cell lines (LCLs), Morag et al151 identified CHL1 as a selective serotonin reuptake inhibitor (SSRI) sensitivity biomarker. The same group reported Sodium butyrate that specific miRNAs may be implicated in SSRI sensitivity of LCLs.152 They examined genome-wide expression profiling with miRNAs in LCLs exhibiting high or low sensitivities to paroxetine. They found that miR-1513p had a 6.7-fold higher basal expression in paroxetinesensitive LCLs, which was correlated with lower expression of CHL1, a target of miR-151-3p. The additional miRNAs miR-212, miR-132, miR-30b*, let-7b, and let-7c also differed by > 1.5-fold between the two LCL groups. These results suggest a possible therapeutic value of miRNAs in responders vs nonresponders to antidepressant treatment in MDD patients.

Functional neuroimaging studies typically manipulate cognitive demand of tasks by changing executive load (e.g., n-back tasks; Owen et al. 2005 for meta-analysis) or number of items on the display over

a temporal delay (e.g., Sternberg tasks; Manoach et al. 1997; Rypma et al. 1999, 2002; Inhibitors,research,lifescience,medical Jha and McCarthy 2000). Researchers have also identified a set of areas that are active when a cognitive task is not required, during rest (e.g., Spreng et al. 2009 for meta-analysis). Knowledge of the brain areas Inhibitors,research,lifescience,medical that underlie cognitive load versus rest activity is expanding, but their interrelation is not well understood. We used functional magnetic resonance imaging (fMRI) and a working memory task with graded increases in cognitive load (Arsalidou et al. 2010), to examine, using linear regression, whole-brain changes in activity as a function of task difficulty. A classic working memory protocol used to manipulate cognitive load is the n-back task. In a typical n-back paradigm, participants view

a series of stimuli and indicate whether the current stimulus matches the stimulus n items earlier in the series. As n increases, the number of Inhibitors,research,lifescience,medical interpolated stimuli between criterion and target increases, and thus cognitive load increases. Cognitive demand increases Inhibitors,research,lifescience,medical qualitatively (e.g., 0-back, recognition, 1-back, maintenance, 2-back, maintenance and monitoring), and because cognitive load increases nonlinearly from one level to the next, these changes are not easily quantifiable. In a coordinate-based also meta-analysis of 24 n-back studies, Owen et al. (2005) identified six cortical regions that were reliably activated by n-back tasks. In prefrontal regions, activity was typically elicited in inferior frontal (BA 45/47), middle frontal (BA 9/46), and anterior medial frontal gyri (BA 10; Owen et al. 2005). Other areas included the dorsal cingulate gyrus (BA 32), the premotor cortex (BA 6), and parietal regions (BA 7/40; Owen et al. 2005). In this study, by manipulating cognitive load, we expected to replicate this set of areas typically found with adults, and also show how brain activity elicited by graded increases in cognitive load might also affect activity found in the control conditions (i.e., no task).

In the last 20 years, 256 cases of the central nervous system IKK inhibitor hydatid cyst have been published from Iran. This cyst site accounted for the third common site of the hydatid cyst after the lung and liver. The hydatid cyst of the spinal cord is less common. According to the recent literature, this cyst accounts for about 1% of all the cases of the hydatid cyst.29 In this location, the intravertebral discs are usually preserved because the disease

tends to progress beneath the periosteum and ligaments.29 The orbital hydatid cyst accounts for about 1-2% of the cases in the previous literature and is most commonly detected in childhood.158 Our survey yielded 36 cases of the orbital hydatid Inhibitors,research,lifescience,medical cyst published from Iran.15,26,27 Musculoskeletal System Osseous hydatid disease and muscular hydatidosis are uncommon and account for 0.5-4% and 0.5-2.5% of all hydatidosis cases, respectively (in endemic areas).159 The most common locations of the osseous hydatid cyst are the vertebra, pelvis, and long bones Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical in the previous records from other parts of the world.41 However, in the published cases form Iran, there were 55 cases with variable locations such as the long bone, mandible, maxilla, and pelvis.38-54 Muscle involvement of the hydatid cyst is reported as an uncommon location, because of high lactic acid, which is not a suitable environment for the parasite.58 Cardiovascular

System The heart and large blood vessels also have been reported as the common unusual body sites of the hydatid cyst in endemic areas of the world, Inhibitors,research,lifescience,medical accounting for 0.5-2% of all the reported cases.160 The diagnostic method unique for this part of the body is echocardiography, which has been claimed as the method of choice for the diagnosis of the cardiac hydatid cyst. Nonetheless, CT scan and MRI are also helpful in other parts of the body.161 Kidney and Urinary Tract The kidney is the most common location

in the urinary tract and has been reported Inhibitors,research,lifescience,medical in about 2-3% of all cases of the hydatid cyst.83 In many of the previous reports from Olopatadine other parts of the globe, the kidney is reported as the third common site of the hydatid cyst after the liver and lung.162-164 In our survey of the published cases from Iran, however, the renal hydatid cyst was the fourth most common location of the hydatid cyst. The clinical symptoms are nonspecific, and the only interesting and diagnostic symptom reported is hydatiduria.163 The hydatid cyst of the urinary bladder is even less common, and only 2 cases were published from Iran.6,86 This cyst can also present with hydatiduria and is, otherwise, extremely difficult to diagnose before surgery.164 Spleen Less than 2-5% of the cases of the hydatid cyst have been reported from the spleen.165 There were 20 cases of the splenic hydatid cyst published from Iran.

Table 8 Evaluation of DE MTDS administration area (mean ± SD; n = 6). For the study of egg-albumin induced paw edema in rats, the swelling degree was calculated from the following equation: Swelling  degree=C2−C1; (8) C1 is circumference before administration and C2 is circumference after administration. 2.8. Xylene-Induced Ear Swelling in Mice The mice weighing 20 ± 2g were placed into three random groups (n = 9), and each animal received 50μL xylene on the anterior and posterior surfaces of the right ear lobe 1h after intragastric injection of Fenli (7.0mg/kg based on DE) and transdermal administration of DE MTDS (7.0mg/kg

based on DE); the left ear was considered as a control. The remaining Inhibitors,research,lifescience,medical group without drug treatment was used as the control Inhibitors,research,lifescience,medical group. Two hours later, the animals were sacrificed by cervical dislocation and both ears were sampled. Circular sections were taken, using a cork borer with a diameter of 8mm, and weighed immediately. The degree of ear swelling was calculated based on the T0070907 concentration weight of the left ear without application of xylene [16]. For the study

of egg-albumin induced paw edema in rats, the swelling degree was calculated from the following equation: Swelling  degree  (SD)  =weigh  of  right  ear−weigh  of  left  ear,Inhibition  rate=(SD1−SD2)SD1×100%, Inhibitors,research,lifescience,medical (9) with SD1, SD2 of the control group and SD2, SD of the test group. 2.9. Acetic Acid-Induced Abdominal Constriction in Mice Mice weighing 20 ± 2g were placed into three groups (n = 9) and given intraperitoneal injections of 0.25mL/10g body weight of 1.5% acetic acid solution in saline 1h Inhibitors,research,lifescience,medical after intragastric injection of Fenli (7.0mg/kg based on DE) and transdermal administration of DE MDTS (7.0mg/kg based on DE). The remaining Inhibitors,research,lifescience,medical group without drug treatment was used as the control group. Writhing was characterized by a wave of contraction of the abdominal musculature followed by the extension of the hind limbs. The frequency of writhing observed was recorded 20min after

the injection of acetic acid [17]. For the study of acetic acid-induced abdominal constriction in mice, the pain-inhibition rate was calculated from the following equation: Mannose-binding protein-associated serine protease Pain-inhibition  rate=(Wc−Wt)Wc×100%; (10) Wc is writhing count of the control group; Wt is writhing count of the test group. 2.10. Skin Irritation Study Draize patch test was carried out using rat as the animal model. Healthy female Sprague-Dawley rats weighing 220 ± 20g were used in this study. The abdominal hair was shaved using an electric clipper carefully and allowed to heal for 24h. The animals were divided into two groups randomly with six animals in each group. The first group was treated with the optimized formulation spraying on the patch of preshaved skin and occluded with adhesive tapes. The second group was only occluded with adhesive tapes without drug treatment.

Sample size calculations utilized an estimated effect size, determined based upon preliminary testing in the model. Using a significance

level of 0.05 and power of 80%, the sample size needed for the trial was conservatively estimated at 12 subjects in each group, 48 total. Results Forty-eight participants were Gamma-secretase inhibition recruited from October 2011 to December 2011 with no excluded participants. The process of subject selection and flow throughout the study is Inhibitors,research,lifescience,medical summarized in a flow-diagram in accordance with the CONSORT Statement (Figure 2) [13,14]. Notably, one participant who should have been assigned to the 60 mL group according to the randomization sequence was incorrectly allocated to and received the 30 mL assignment due to a communication error. This individual was analyzed in the 60 mL group as per intention to treat principles but we also conducted a per protocol analysis of the primary outcome to assess for any potential impact this may have Inhibitors,research,lifescience,medical had on the primary outcome. The

per-protocol analysis failed to show any difference in the primary outcome Inhibitors,research,lifescience,medical analysis result. Further study analyses were therefore conducted using only an intention-to-treat analysis. Figure 2 The Pediatric Fast Fluid Trial flow diagram. No participants were excluded from initial 48 subject recruitment. All subjects completed protocol to analysis. Initial allocation called for 1:1:1:1 syringe size distribution, however one subject was mistakenly … Baseline demographics of the participants as gathered from the post-intervention questionnaire are seen in Table 1. Participants indicated that they were most comfortable using the ‘disconnect-reconnect’ technique as their preferred method of fluid administration for children in shock (48%), though many also preferred the ‘push-pull’ Inhibitors,research,lifescience,medical technique (27%); regular infusion pump was also preferred by 14% (Figure 3). Respondents were asked

to choose one preferred method, however several circled more than one answer on their post-test questionnaire Inhibitors,research,lifescience,medical (48 subjects provided 54 responses). Four respondents did not provide an Rolziracetam answer. Table 1 Baseline demographics of trial participants Figure 3 Preferred techniques of rapid fluid resuscitation as reported by participants. The majority of respondents reported preference for the ‘disconnect-reconnect’ technique of fluid bolusing. The next most commonly cited preference was the … The primary outcome of total fluid delivery time significantly differed according to syringe size based on our analysis with one-way ANOVA at p = 0.0012 (Table 2). Post Hoc analysis with Tukey’s HSD demonstrated a significant difference in fluid administration time when comparing the 10 mL group to both the 30 mL and 60 mL groups respectively (Table 3). There did appear to be a trend towards superiority of the 30 mL and 60 mL groups over the 20 mL group, but this was not statistically significant (Figure 4).

However, some patients may receive optimal benefit from 125 to 500 mg/day.6 Additional unpleasant symptoms such as chest

pain, seizures, hepatotoxicity, renal failure, and even death have been reported in severe cases.6,62 Controlled trials of disulfiram versus placebo have not demonstrated significant improvement over placebo,63,64 and metaanalyses have only shown slight improvement in drinking.65 A large Veterans Cooperative Study with over 600 subjects found, however, that disulfiram may be effective Inhibitors,research,lifescience,medical in patients with no major comorbid psychiatric disorder and who were motivated for abstinence.64 More recently, an evaluation of subjects with current depression on disulfiram reported lower craving over time than subjects with depression on naltrexone.66 The utility of HSP activator combining disulfiram with other therapeutic interventions has also been examined. In a trial of disulfiram and acamprosate, the number of abstinent days was greater when utilizing a combination of disulfiram and acamprosate than using Inhibitors,research,lifescience,medical either medication alone.67 Naltrexone acts as an antagonist at the Inhibitors,research,lifescience,medical opioid receptors, which are known to mediate the rewarding effects of alcohol and thus thought to reduce desire or craving of alcohol. Studies have found that naltrexone is more effective than placebo in promoting abstinence, reducing heavy drinking days and decreasing relapse rates,6,68-70 particularly

when it is combined with cognitive behavioral therapy71-73 Naltrexone has also shown greater efficacy when compared with acamprosate. In a randomized controlled trial comparing the efficacy of acamprosate and naltrexone in the treatment of alcohol dependence, significant increases in time to first relapse was seen in those receiving naltrexone in Inhibitors,research,lifescience,medical subjects with no depression and low dependency.74 Furthermore, combined pharmacotherapy studies have also demonstrated Inhibitors,research,lifescience,medical that naltrexone

administered with behavioral therapy can significantly reduce the risk of heavy drinking.75 Naltrexone is prescribed as 50 mg oral administration, most commonly for 12 weeks, and can also be given as a long-acting depot formulation every 4 weeks. Acamprosate attenuates alcohol desire or craving by normalizing the dysregulation of N-methyl-D-aspartate (NMDA)-mediated glutaminergic excitation that occurs in alcohol withdrawal and early abstinence. Acamprosate, and when given at 2 g administered three times daily, has increased abstinence by 50% in over 3000 patients across a dozen clinical trials.76-78 Side effects such as diarrhea are generally well tolerated. A placebo-controlled trial enrolled 272 patients and treated patients for 48 weeks. Compared with placebo, acamprosate-treated alcoholdependent patients had twice the rate of sustained abstinence at 48 weeks (43% vs 21%), and this difference from placebo was sustained at 96 weeks after starting the medication (37% vs 17 %).

101 Population-based cohort studies102,103 have found that compromised general cognitive ability in late adolescence is a strong predictor of subsequent schizophrenia risk. Family studies indicate that a proportion of the unaffected first-degree relatives of index cases of schizophrenia display similar patterns of deficit in an attenuated form.104-106 The balance of evidence suggests that cognitive dysfunction meets most of the criteria of an endophenotype in schizophrenia. This is underscored by the meta-analysis by Heinrichs and Zakzanis107 of 204 studies published between

1980 and 1994 (a total of 7420 schizophrenia patients and 5865 controls), Inhibitors,research,lifescience,medical in which effect sizes (Cohen’s d) and the U statistic (degree of non-overlap) were calculated for 22 neurocognitive test variables ranging from IQ, verbal

memory, and attention to executive function and language. Although no single test or cognitive construct was capable of separating perfectly schizophrenia patients from normal controls, 7 measures achieved effect sizes greater than 1.0 (6070% Inhibitors,research,lifescience,medical non-overlap between the cases and controls): verbal memory (1.41), bilateral motor skills (1.30), performance IQ Inhibitors,research,lifescience,medical (1.26), the continuous performance task (1.16), word fluency (1.15), the Stroop task (1.11), and WAIS-R IQ (1.10). Although a subset of ~50% of patients had nearly normal performance, significant cognitive impairment was Inhibitors,research,lifescience,medical common in schizophrenia and exceeded the deficits found in some neurological disorders, justifying the view that “schizophrenia is a neurological disorder that manifests itself in behavior.107 There is, at least, a preliminary evidence that composite cognitive endophenotypes have the capacity to identify genetically distinct subtypes of schizophrenia.108 Inhibitors,research,lifescience,medical Conclusion: the

way forward More than a century since the delineation of dementia praecox by Kraepelin, the etiology, neuropathology, and pathophysiology of schizophrenia remain Ganetespib elusive. Despite the availability of criteria allowing reliable diagnostic identification, schizophrenia essentially remains a broad clinical syndrome defined by reported subjective experiences (symptoms), loss of function (behavioral impairments) and variable patterns of course. Research has identified a number of putative biological markers associated Ribonucleotide reductase with the disorder, including neurocognitive dysfunction, brain dysmorphology, and neurochemical abnormalities. Yet none of these variables has to date been definitively proven to possess the sensitivity and specificity expected of a diagnostic test. Genetic linkage and association studies have targeted multiple candidate loci and genes, but failed to demonstrate that any specific gene variant, or a combination of genes, is either necessary or sufficient to cause schizophrenia. Thus, the existence of a specific brain disease underlying schizophrenia remains a hypothesis.
