Adjuvant chemotherapy in the absence of radiation has not, however, been shown to improve local control. Trials addressing this issue accrued patients during the pre-TME era. The NSABP R-01 trial

compared observation vs. adjuvant radiotherapy vs. adjuvant chemotherapy (fluorouracil, semustine, and vincristine) (2).

Table 6 NSABP R-01(2) Similarly, a prospective trial by the Gastrointestinal Tumor Study Group did not show a decrease in local control with the addition of chemotherapy alone to surgery. This trial randomized patients to surgery followed by observation, chemotherapy, radiotherapy or chemoradiotherapy (1),(26),(27). The trial was closed early due Inhibitors,research,lifescience,medical to inferiority of the surgery alone arm and thus the data was not sufficiently powered to distinguish outcomes all four treatment arms. At a median of 80 Inhibitors,research,lifescience,medical months, the locoregional recurrence and overall survival were improved by adjuvant

chemoradiotherapy, but not by either therapy alone (Table 7). Table 7 GITSG 71-75(1),(26),(27) Randomized trials showed that the addition of radiation to chemotherapy improved local control in the pre-TME era, but the benefit of adding radiation to modern chemotherapy following TME is not known (1), (19), (26). The Dutch study of TME with or without short course preoperative radiation therapy proved that the addition Inhibitors,research,lifescience,medical of radiation to TME improves local control, but this trial did not use chemotherapy. It is possible, though not proven, that the lower disease burden afforded by modern surgical techniques may be amenable to local control with chemotherapy, particularly with the use of newer, more active chemotherapy regimens. These advances Inhibitors,research,lifescience,medical may obviate the benefit of adjuvant radiotherapy in some

patients. The most notable advances in chemotherapy for rectal cancer are oxaliplatin and irinotecan. Oxaliplatin is a platinum derivative that acts as an alkylating agent and impairs DNA replication and transcription. A randomized trial by de Gramont et al. showed improvement in response rate in advanced colorectal cancer from 22% with infusional isothipendyl 5FU plus leucovorin to 50.7% with infusional 5FU, leucovorin, and oxaliplatin (FOLFOX), P=0.0001 (28). Irinotecan is a topoisomerase I inhibitor. A randomized trial by Douillard et al. showed improvement in response rate in advanced colorectal cancer from 22% with infusional 5FU plus leucovorin to 35% with infusional 5FU, leucovorin, and irinotecan (FOLFIRI), P<0.005 (29). While response rates are higher with the addition of newer agents to 5FU, it is unknown of these agents can provide equivalent local control compared to radiation.

​(Fig.1A).1A). Our previous observations in 3-month-old B6eGFPChAT mice (Nagy and Aubert 2012) revealed enhanced VAChT protein expression and here, we confirm that at 6 months of age, VAChT overexpression is sustained. The expression of VAChT in B6eGFPChAT mice was compared with B6 controls using Western blot analysis to detect cholinergic immunoreactivity in various regions of the central nervous system. Western blot targeting VAChT revealed a diffuse doublet at the predicted size of 70 kDa (Fig. ​(Fig.1B).1B). Quantification Inhibitors,research,lifescience,medical of the VAChT band intensity revealed a significant two- to threefold increase

of VAChT protein in B6eGFPChAT compared with B6 control mice (Fig. ​(Fig.1C).1C). The enhanced level of VAChT protein was found in the cortex (t(4) = 8.752; P = 0.001), striatum (t(4) = 4.494; P = 0.046), and hippocampal formation (t(4) = 5.323; P = 0.006) (Fig. ​(Fig.1D).1D). Western blots and quantification of ChAT (Fig. ​(Fig.1D1D and E) and Inhibitors,research,lifescience,medical CHT (Fig. ​(Fig.1F1F and G) revealed no significant Inhibitors,research,lifescience,medical change in protein expression

in any of the regions that were analyzed. Figure 1 VAChT protein is overexpressed in B6eGFPChAT mice. (A) RP23-268L19-EGFP transgene is expressed throughout the central nervous system of B6eGFPChAT mice including cortical, striatal, and hippocampal regions (green). Punctate VAChT immunoreactivity is present … B6eGFPChAT mice exhibit unaltered motor function Inhibitors,research,lifescience,medical and coordination To measure the effect of increased VAChT on peripheral motor function, we first assessed forelimb grip strength using a digital tension gauge. B6eGFPChAT mice produced a peak tension of 0.268 kg which was not found to be significantly different from B6 control mice that produced 0.260 kg of peak tension (t(18) = 0.416; P = 0.682) (Fig. ​(Fig.2A).2A).

In addition, no learn more statistical difference was found between B6eGFPChAT and B6 control mice when measuring wire hang fatigue (two-way repeated measures ANOVA revealed no significant Inhibitors,research,lifescience,medical genotype factor, F(1,36) = 0.052; P = 0.822, and the expected trial factor, F(2,36) = 11.04; P < 0.001) (Fig. ​(Fig.2B)2B) or total hanging time performance (t(18) = 0.229; P = 0.822) (Fig. ​(Fig.22C).

(B and C) Time spent hanging upside-down from a wire grid in each of three consecutive trials (B) … We considered that the effect of VAChT overexpression might only be detectable during activities combining endurance, fine motor coordination, and balance. As such, performance on the rotarod was assessed through the latency to fall off the rotating cylinder. Both B6eGFPChAT and B6 control mice improved significantly from trial 1 to trial 10 (two-way repeated measures ANOVA trial factor, F(9,162) = 8.653; P < 0.

In the left ventricle, fibers in the subepicardium run in a left-

In the left ventricle, fibers in the subepicardium run in a left-handed direction, fibers in the mid layer run circumferentially, and

fibers in the subendocardium run in a right-handed GS 9973 direction (Fig. 1). These myocardial fibers are connected to each other, with a smooth transition from subendcardium to mid layer, and then to subepicardium, about the long-axis. Contraction of these three layers of myocardial fibers causes not only longitudinal, circumferential, and radial movements of the heart, but also contortion of the myocardium. Inhibitors,research,lifescience,medical Fig. 1 Myocardial fiber orientation and direction of rotation. Myocardial fibers in the subepicardium helically Inhibitors,research,lifescience,medical run in a left-handed direction, fibers in the mid layer run circumferentially, and fibers in the subendocardium helically run in a right-handed direction. … Myocardial fibers on the subepicardial side run in a left-handed direction, and contraction of these fibers will cause the base to rotate in a clockwise direction and the apex to rotate in a counterclockwise direction. Myocardial fibers on the subendocardial side run in a right-handed direction, and contraction

of these fibers will cause the base Inhibitors,research,lifescience,medical to rotate in a counterclockwise direction and the apex to rotate in a clockwise direction (Fig. 2). This means that rotations caused by the subepicardium and subendocardium are in opposite directions. Why, then, does clockwise rotation of the base and counterclockwise rotation of the apex become significant? In other words, why is it the rotation of the subepicardial side that becomes significant? This is explained by the difference Inhibitors,research,lifescience,medical in the radius of rotation of the subepicardium Inhibitors,research,lifescience,medical and subendocardium (Fig. 3). The radius of rotation of the subepicardium is

greater than that of the subendocardium. The subepicardium consequently provides greater torque than the subendocardium, as a result of which the rotation of the subepicardium is significantly expressed. Fig. 2 Myocardial contraction and rotation. When myocardial fibers on the subepicardial side contract, clockwise rotational torque is produced at the base and counterclockwise rotational torque at the apex. When myocardial fibers on the subendocardial side contract, … Fig. 3 Opposite rotation at the base and Florfenicol apex. Subepicardial radius is larger than subendocardial radius (r2 > r1). Therefore, subepicardial rotational torque is larger than subendocardial rotational torque (R2 > R1). Why is Twist Motion Necessary? The degree of shortening of myocardial fibers is of the order of 15-20% at most. If ejection was simply the result of contraction of myocardial fibers, the ejection fraction would be 15-20%, whereas the actual ejection fraction of the human heart is 60-70%. This is due to the involvement of twisting.

Studies have found that in general, racial/ethnic minority older

Studies have found that in general, racial/ethnic minority older adults were less likely than their non-Hispanic White peers to use formal mental health services, but more likely to use traditional self-care regimens and prayer and to turn to their informal support networks and to clergy (Snowden 2001). These racial/ethnic differences in help-seeking behaviors may be due in part to cultural differences in the way a person’s symptoms are manifested, defined, Inhibitors,research,lifescience,medical interpreted, and labeled and in the person’s attitudes, values, and knowledge about negative

aspects or perceived barriers (i.e., side effects, expense, inconvenience) of pharmacotherapy (Andersen 1995; Lewis–Fernandez and Diaz 2002). Interestingly, though, our findings show that Hispanic older adults did not differ from their non-Hispanic peers in their likelihood of taking antidepressants. The findings also show that the participants’ perception of effectiveness of antidepressants tended to match their depressive Inhibitors,research,lifescience,medical symptoms, as those with higher HAMD scores reported Inhibitors,research,lifescience,medical lower effectiveness ratings. Although those aged 70 or older also reported lower effectiveness ratings, sex and race/ethnicity were not

significant predictors of perceived effectiveness of antidepressants. This suggests that a majority of the current users, regardless of sex and race/ethnicity, perceive the medication as being at least somewhat effective. However, as those who had been dissatisfied Inhibitors,research,lifescience,medical with antidepressant use were likely to have stopped using them, this finding needs to be interpreted with caution. In many efficacy trials of antidepressants in the treatment of late-life depression, antidepressants were more effective than placebos,

and no difference was found in antidepressant class outcomes among older adults with major depression or nonspecific depression severity, although Inhibitors,research,lifescience,medical SSRIs may be better tolerated than tricyclics (Roose and Schatzberg 2005; Reynolds et al. 2006). However, a meta-analysis of the use of second-generation antidepressants almost in late life found their effects tend to be modest (Nelson et al. 2008). A previous study also suggested that older adults with the greatest comorbidity may be at high risk for poor depression treatment outcomes (Kales and Valenstein 2005), while another study found that antidepressants are effective in depressed patients with a range of comorbid physical conditions (Sheikh et al. 2004). Despite the generally positive perception of effectiveness of antidepressants among the study participants who had been taking the medications for at least 8 weeks (and some for a much longer period), the PXD101 in vitro continuing depression—either nonremitted or in partial remission—of all of them suggests that their care may not have been well monitored by the prescribing clinician.

In the following sections, I shall endeavor to show to what extent the current diagnostic system has furthered or impeded progress. The group of mood disorders, in particular the construct of major depression, will be used as a paradigm, but the same reasoning can be applied to most of the diagnostic see more constructs currently distinguished. Problems of validity Predictive validity

is the basic quality any diagnostic construct should possess. A diagnosis, once made, should allow reliable prognostication of symptoms, cause, course, outcome, and response Inhibitors,research,lifescience,medical to treatment. This is clearly not the case as far as the diagnostic construct of major depression is concerned: The diagnosis of major depression is based on evidencing Inhibitors,research,lifescience,medical X out of a scries of Y symptoms, irrespective of which ones. This construct therefore encompasses a wide range of syndromes without providing any information on the type of depressive syndrome thus observed. Major depression can be precipitated by a variety of etiological factors, psychological, biological, or related

to living conditions. In some instances, no precipitating factors are demonstrable. With regard to pathophysiology, current hypotheses postulate a causal role of serotonergic dysfunction and hypothalamo-pituitary-adrenocortical (HPA) axis disturbances. These Inhibitors,research,lifescience,medical have indeed been found to be associated with major depression in some patients, Inhibitors,research,lifescience,medical but not in others, without these patient subgroups coinciding with any of the currently distinguished depression subtypes. Furthermore, disturbances of these systems are not specific to depression, but occur in other diagnostic categories as well.3-4 Course and outcome also fail to show a characteristic pattern.5,6 Inhibitors,research,lifescience,medical Some patients only develop a single episode, whereas the majority of them experience several. One patient may recover completely, another will suffer

from residual symptoms, and in another still chronicity will set in.7,8 Treatment response, finally, is difficult to predict. Antidepressants may achieve complete recovery, partial response, or no response at all. Psychological interventions will be helpful in some patients, or totally useless in others. The construct of major depression therefore shows great Liothyronine Sodium variability at almost every diagnostic level. Hence there is no question of any predictability being associated with the diagnostic characteristics: no single characteristic is reliably predictive of any other. In other words, the predictive validity of this construct is all but null. Not only does the construct of major depression encompass a wide range of syndromes, but in the majority of cases it is also associated with other disorders, most notably personality and anxiety disorders.10-13 Thus it appears that major depression is not so much a diagnostic entity as a diagnostic multiplicity.

This has been applied recently for the identification of pathways

This has been applied recently for the identification of pathways altered upon

differentiation of inner cell mass and trophectoderm in the human blastocyst47 and upon hormoneinduced aging of the human skin.48 The procedure is based on pathway annotation (for example provided by the Kyoto Encyclopedia of Genes and Genomes [KEGG] pathway database).49 This information is then translated into a two-dimensional statistical test problem that involves Wilcoxon’s signed rank sum test in order to compute a Z-score for each pathway that quantifies the degree of alteration across the different experimental conditions. The results of the pathway analysis Inhibitors,research,lifescience,medical in the latter study, for example, implicate the Caspase inhibitor review involvement of several metabolic pathways in the aging process, such as C21 -steroid hormone metabolism, phospholipid degradation, prostaglandin and leukotriene metabolism, 2,4-dichloro benzoate degradation, and fatty acid biosynthesis. Interestingly, pathways operative Inhibitors,research,lifescience,medical in neurodegenerative disease such as Inhibitors,research,lifescience,medical Huntington’s disease (HD),50,51

dentatorubral-pallidoluysian atrophy (DRPLA),52 and amyotrophic lateral sclerosis (ALS)53 also showed significant age-dependent expression changes. Databases, standardization initiatives, and common platforms It has been recognized that, there is a fundamental need worldwide to share microarray data in order to correlate researchers’ results with already published data. Since for such a task it is necessary to provide the raw data, large microarray databases have been set up as public repositories (for

example the gene expression omnibus (GEO) from NCBI54 and ArrayExpress from EBT55). Functional annotation is provided by the GO consortium.56 Inhibitors,research,lifescience,medical The aim of GO is to maintain a consistent, speciesindependent, functional description of gene products. GO terms have a. defined parent-child relationship and form a directed acyclic graph (DAG). At, the root, of the GO are the three top-level categories – molecular function, biological process, and Inhibitors,research,lifescience,medical cellular component – which contain many levels of child nodes (GO terms) that describe a gene product with increasing specificity. There are several tools for mining these annotations. We have developed the GOblet server that computes GO-term graph annotation for DNA sequences comprising several different sequence databases.57,58 A particular data repository for neuroscience applications is the National Brain Databank, MycoClean Mycoplasma Removal Kit a publicly accessible gene expression repository for the collection and dissemination of results from postmortem studies of neurological and psychiatric disorders. The project has been developed by the Harvard Brain Tissue Resource Center (HBTRC) in collaboration with Akaza Research, as an online resource for the neuroscience community. A further useful database for drug discovery and drug response screening is PharmGKB.

2 On February 11, 1999 the government decided not to follow these recommendations.3 The Ersta Psychiatric Clinic The Ersta Psychiatric Clinic is specifically devoted to treating hospital personnel, its first responsibility being to hospital

personnel from Stockholm County Council area. The Psychiatric Clinic is part of Ersta Inhibitors,research,lifescience,medical Hospital, which is owned by the Ersta Deaconess Society, a nonprofit association in close connection with the Church of Sweden. It has 40 employees, which makes it the smallest psychiatric clinic in Stockholm. Because Ersta does not belong to Stockholm County Council, Ersta Hospital was the only emergency hospital that had not received disaster emergency training. What can we at Ersta do to help the victims? This question was to be often

raised Inhibitors,research,lifescience,medical on the day of the catastrophe and the following days. As Ersta Hospital was not part of the emergency plan, the answer was obvious. Ersta should continue with its habitual health care activities and let the other hospitals concentrate on helping the victims. During the first days, the Psychiatric Clinic at Ersta Hospital kept on with the daily psychiatric workload as planned. However, just two days after the catastrophe, relatives of the Estonia passengers started to call. A company, many employees of Inhibitors,research,lifescience,medical which had been on board the Estonia, also called the clinic asking if we could do something to help since the crisis groups in Stockholm were being shut down. Ersta learned that 7 of the 9 hospitals in Stockholm had shut down their Estonia crisis groups because so few people Inhibitors,research,lifescience,medical had contacted them. Only the two university hospitals, Huddinge Hospital and Karolinska Hospital in Stockholm, intended to keep their crisis groups going, at least for the following two days. The following day, Sweden’s largest morning newspaper carried an article about the distraught relative of a victim who had been turned away after showing up at a crisis center in Stockholm. Ersta Inhibitors,research,lifescience,medical got in touch with the crisis centers at Huddinge and Karolinska, asking them if they were

going to start groups for the relatives. We could picture what would happen when all of the crisis groups had shut down and the relatives’ reactions began to multiply. After several enquiries, Liothyronine Sodium we learned that Huddinge and Karolinska had no intention of selleck chemical starting groups for relatives, leaving it up to Ersta to take the initiative. The weeks after the Estonia disaster The Sunday after the Estonia catastrophe, the decision was made to notify the relatives of the new crisis groups that were being set up at Ersta Hospital. An official memorial service was to be broadcast on the media throughout Sweden, and the Dean of the Church was asked to read a message to the relatives. However, instead, the message was distributed by hand to the persons attending the memorial service. The message wasn’t typed very well and part of it was in longhand.

This same patient had a

This same patient had a preoperative barium esophogram suggestive of an esophageal stricture. Two other patients had preoperative findings suggestive of invasive disease. The patient with a 1.6 cm tumor staged as T1b had esophageal thickening up to 7 mm noted on a preoperative learn more computed tomography scan and on preoperative endoscopy multiple

esophageal nodules were noted. The patient with T1b staging and a 1.5 cm Inhibitors,research,lifescience,medical tumor had nodular, ulcerated lesions on endoscopy and a preoperative endoscopic ultrasound was suggestive of submucosal involvement (Table 2). None of the other patients with invasive cancer or intramucosal carcinoma had radiologic or endoscopic evidence suggestive of cancer on preoperative testing. Table 2 Preoperative testing of patients with invasive adenocarcinoma Despite a preoperative diagnosis of HGD 2 patients staged as T3 had radiologic and endoscopic evidence to suggest invasive cancer. Two patients with subsequent T1b staging postoperatively also had preoperative suspicion for malignancy. Thus, 4 patients with preoperative HGD had occult carcinoma detected postoperatively, for an occult Inhibitors,research,lifescience,medical incidence rate of 5.9% (4/68). We performed a time based analysis, based

on date of surgical resection to see if the rate of adenocarcinoma in association with HGD decreased over time. We divided patients to 2 groups: those who Inhibitors,research,lifescience,medical underwent surgery between 1993 and 2000, and those between 2000 and 2007. Three of 20 patients (15%) were found to have adenocarcinoma

in first group, while 9 of 48 (18.8%) were found to have adenocarcinoma Inhibitors,research,lifescience,medical in second group (P=0.77). Even when the groups were analyzed from 1993 to 2003 and 2004 to 2007, no significant difference was found (8/40 and 4/28 respectively, P=0.379). Discussion In this large surgical series examining adenocarcinoma in Barrett’s esophagus with a preoperative diagnosis of high grade dysplasia, we report an overall prevalence of adenocarcinoma of 17.6% with Inhibitors,research,lifescience,medical 11.7% invasive and 5.9% occult. This is in contrast to previous early surgical reports where a much higher rate of adenocarcinoma was observed. In the meta analysis of 23 studies involving 441 patients undergoing surgery for HGD, the pooled rate of adenocarcinoma was 39.9% (12). However, in 14 studies within the meta analysis where a distinction between intramucosal and invasive carcinoma was possible and the intramucosal cancers were excluded, the rate of invasive adenocarcinoma fell to 12.7%, consistent with our observation. In another recent surgical series, the rate of invasive adenocarcinoma those at surgery for HGD was 6.7% (4/60) (14). Several predictors of invasive carcinoma in the setting of HGD have been recognized. Nodular lesions in HGD have been shown to be at a higher risk for adenocarcinoma (15). A recent study analyzed pooled data from multiple studies, and showed that visible lesions at endoscopy are associated with a higher risk of submucosal invasion, although statistical significance was not reached (12).

Participants said VC made it possible to work more effectively and as one team.

However, cooperation between participants is different on VC than with telephones, and need to be learned [Appendix 1C]. Communication and team work had to be balanced with the need for working independently. Rules for communication had to Inhibitors,research,lifescience,medical be set. Most important, those at LYB wanted to work uninterrupted during the first minutes after patient arrival. UNN doctors noticed that discussions of 26s Proteasome structure diagnostics and treatment within their own group were disturbing the LYB teams, which at times made them mute their microphone. This option was agreed should be used more [Appendix 1D]. Team members at LYB said they relied on oral information, and did not need images of their colleagues at UNN. Inhibitors,research,lifescience,medical Still they found facial contact to ease communication, and VC beneficial for time-critical clinical decisions. Also, they believed visual information gives a better foundation for decision-making and had more confidence in

treatment advice given by specialists during VC [Appendix 2A]. The specialists said VC made it possible to use “the clinical eye” and that they sometimes observed matters that LYB doctors or nurses did not. They said it was valuable to monitor the effects of treatment, for example improved blood pressure after intravenous fluid or the reaction Inhibitors,research,lifescience,medical on light of a dilated pupil following intensive treatment efforts. Some specialists felt more psychological involvement and commitment to the patient during Inhibitors,research,lifescience,medical VC, important when prioritising between patients [Appendix 2B]. All believed good patient care were given during both communication modes, but several thought VC improved quality. The use of telephones may result in rumors, while VC improve the certainty and safety, and ensure quality of treatment, doctors said. Doctors at LYB said they might be more willing to do certain procedures with direct guidance and visual support via

VC, even given procedures they do not perform ordinarily. UNN specialists Inhibitors,research,lifescience,medical came together to discuss, which was believed to result in better decisions and improved treatment of patients regardless of communication technology [Appendix 3]. Prior to trials, most below members at LYB expressed uneasiness about the possibility of being “surveilled”. Following trials, they reported less stress than anticipated, and stated that stress decreased after each VC scenario. Nurses reported increased tension when the doctor left the patient room to make telephone calls, in particular when patient condition deteriorated, and argued that this made VC favorable [Appendix 4]. Discussion Virtual team building In this study, VC improved clinical work processes in virtual trauma teams when compared to telephone communication.

Medical interventions have arisen from this basic science work, b

Medical interventions have arisen from this basic science work, beginning with vaccines for infectious diseases, to the more recent development of monoclonal antibodies used to treat a variety of diseases. The total impact of immunological interventions, vaccinations in particular, on human health has been great, especially when considering molecular-based health interventions. Despite these medical successes and a good understanding of basic mechanisms of immunity, it appears as though we have only scratched the surface.

As technological breakthroughs have enabled ever more sophisticated research tools, additional layers of complexity have been revealed. For example, new immune cell subtypes (i.e. cells with differing Inhibitors,research,lifescience,medical functionality at a given condition) have been discovered such that the estimates for the total number of distinct cell subtypes now number in the hundreds. As in Inhibitors,research,lifescience,medical other large complex systems, cooperativity and cross-talk abound in the immune system, and these likely play a key role, as protective immunity is ultimately an emergent phenomenon whose functionality is greater than the sum of its parts. A view with this richness in mind would suggest that our understanding of how the immune system functions as a whole is very limited. At the clinical level, despite its AP24534 importance for general health, many aspects of the immune system are mostly ignored, and little is known about the variation Inhibitors,research,lifescience,medical in immune system components

and their functions. The standard “complete blood count” (CBC), one of the most commonly prescribed tests by physicians, is indicative of a recent infection or extreme disease cases such as drastic reduction in cell counts (Figure 1A). First used clinically in 1957, the test enumerates the five major leukocyte Inhibitors,research,lifescience,medical classes in blood based on cell shape and size (later automated versions of this assay replaced shape with electrical impedance). Yet enumeration of the many immune

cell subtypes, discovered since and identified through the specific expression of protein markers, is not achievable through a CBC test. Inhibitors,research,lifescience,medical In specific cases, flow cytometry is Tolmetin used clinically for enumerating additional cell subsets. Yet such profiling is performed only in specific disease cases to confirm a disease association (e.g. TH17 cell dysfunction in autoimmunity), or to monitor immune reconstitution (e.g. B, CD4+/CD8+ T cells ratio in bone-marrow transplant) rather than prospectively for prevention or early detection. Moreover, such clinical immunology testing assays are performed at a cell subset resolution far below the complexity known to exist in the immune system, yielding partial results inferred over heterogeneous cell types. With such scant collected data, the clinical implication of fluctuations of immune cell subsets among either healthy or diseased individuals is not known, nor is the relationship between subsets quantified or normal ranges tailored to an individual’s background.
