Abstract
Deficits in social cognition and metacognition impact the course of psychosis. Sex differences in social cognition and metacognition could explain heterogeneity in psychosis. 174 (58 females) patients with first-episode psychosis completed a clinical, neuropsychological, social cognitive, and metacognitive assessment. Subsequent latent profile analysis split by sex yielded two clusters common to both sexes (a Homogeneous group, 53% and 79.3%, and an Indecisive group, 18.3% and 8.6% of males and females, respectively), a specific male profile characterized by presenting jumping to conclusions (28.7%) and a specific female profile characterized by cognitive biases (12.1%). Males and females in the homogeneous profile seem to have a more benign course of illness. Males with jumping to conclusions had more clinical symptoms and more neuropsychological deficits. Females with cognitive biases were younger and had lower self-esteem. These results suggest that males and females may benefit from specific targeted treatment and highlights the need to consider sex when planning interventions.

Abstract
BACKGROUND Patients with chronic kidney disease present with an accumulation of uraemic toxins, which have been identified as pathogenic agents associated with cardiovascular mortality, which is very high is this patient group. A phenomenon common to the progressive renal dysfunction and associated vascular damage, is the abnormal accumulation of extracellular matrix (ECM) proteins in the renal or vascular structures. OBJECTIVE To determine the contribution of uraemia or the uraemic toxins to the production of cytokinins and ECM in aortas of uraemic animals or human aortic smooth muscle cells (HASMCs). MATERIALS AND METHODS Mice were used with uraemia induced by a diet rich in adenine (0.2%) for 2, 4 or 6 weeks. Kidney function was evaluated by means of urine volume, plasma levels of creatinine, urea, fractional excretion of sodium, and vascular damage using histology, as well as protein expression using RT-qPCR. The HASMCs were incubated in vitro with uraemic toxins: p-cresol 10-100 (μg/ml) and indoxyl-sulphate25-100 (μg/ml) alone or simultaneously. The protein expression was evaluated using Western blot and confocal microscopy. RESULTS The administration of adenine produced progressive kidney damage in the mice, thickening of the aortic wall, and increasing the expression of TGF-β1 and ECM proteins. The toxins at high doses and combined also induced the expression of TGF-β1 and ECM proteins by the HASMCs. CONCLUSIONS The uraemia produced by an adenine rich diet or high doses of uraemic toxins induced the abnormal deposit of ECM proteins in the vascular wall or its production by HASMCs. The understanding of the mechanisms that underlie this pathophysiological process may be useful in the prevention of cardiovascular damage associated with the progress of chronic kidney disease, a disease, at the moment that is irreversible and occasional silent until its diagnosis in advanced stages.

Abstract
The development of insulin resistance is characterized by the impairment of glucose uptake mediated by glucose transporter 4 (GLUT4). Extracellular matrix changes are induced when the metabolic dysregulation is sustained. The present work was devoted to analyze the possible link between the extracellular-to-intracellular mediator integrin-linked kinase (ILK) and the peripheral tissue modification that leads to glucose homeostasis impairment. Mice with general depletion of ILK in adulthood (cKD-ILK) maintained in a chow diet exhibited increased glycemia and insulinemia concurrently with a reduction of the expression and membrane presence of GLUT4 in the insulin-sensitive peripheral tissues compared with their wild-type littermates (WT). Tolerance tests and insulin sensitivity indexes confirmed the insulin resistance in cKD-ILK, suggesting a similar stage to prediabetes in humans. Under randomly fed conditions, no differences between cKD-ILK and WT were observed in the expression of insulin receptor (IR-B) and its substrate IRS-1 expressions. The IR-B isoform phosphorylated at tyrosines 1150/1151 was increased, but the AKT phosphorylation in serine 473 was reduced in cKD-ILK tissues. Similarly, ILK-blocked myotubes reduced their GLUT4 promoter activity and GLUT4 expression levels. On the other hand, the glucose uptake capacity in response to exogenous insulin was impaired when ILK was blocked in vivo and in vitro, although IR/IRS/AKT phosphorylation states were increased but not different between groups. We conclude that ILK depletion modifies the transcription of GLUT4, which results in reduced peripheral insulin sensitivity and glucose uptake, suggesting ILK as a molecular target and a prognostic biomarker of insulin resistance.

Abstract
Two processes are associated with progressive loss of renal function: 1) decreased aquaporin-2 (AQP2) expression and urinary concentrating capacity (Nephrogenic Diabetes Insipidus, NDI); and 2) changes in extracellular matrix (ECM) composition, e.g. increased collagen I (Col I) deposition, characteristic of tubule-interstitial fibrosis. AQP2 expression is regulated by both the ECM-to-intracellular scaffold protein integrin-linked kinase (ILK) by NFATc/AP1 and other transcription factors. In the present work, we used in vivo and in vitro approaches to examine ILK participation in NFATc3/AP-1-mediated increases in AQP2 gene expression. Both NFATc3 knock-out mice and ILK conditional-knockdown mice (cKD-ILK) display symptoms of NDI (polyuria and reduced AQP2 expression). NFATc3 is upregulated in the renal medulla tubular cells of cKD-ILK mice but with reduced nuclear localization. Inner medullary collecting duct mIMCD3 cells were subjected to ILK depletion and transfected with reporter plasmids. Pharmacological activators or inhibitors determined the effect of ILK activity on NFATc/AP-1-dependent increases in transcription of AQP2. Finally, mIMCD3 cultured on Col I showed reduced activity of the ILK/GSK3β/NFATc/AQP2 axis, suggesting this pathway is a potential target for therapeutic treatment of NDI.

Abstract
BACKGROUND Aims were to assess the efficacy of metacognitive training (MCT) in people with a recent onset of psychosis in terms of symptoms as a primary outcome and metacognitive variables as a secondary outcome. METHOD A multicenter, randomized, controlled clinical trial was performed. A total of 126 patients were randomized to an MCT or a psycho-educational intervention with cognitive-behavioral elements. The sample was composed of people with a recent onset of psychosis, recruited from nine public centers in Spain. The treatment consisted of eight weekly sessions for both groups. Patients were assessed at three time-points: baseline, post-treatment, and at 6 months follow-up. The evaluator was blinded to the condition of the patient. Symptoms were assessed with the PANSS and metacognition was assessed with a battery of questionnaires of cognitive biases and social cognition. RESULTS Both MCT and psycho-educational groups had improved symptoms post-treatment and at follow-up, with greater improvements in the MCT group. The MCT group was superior to the psycho-educational group on the Beck Cognitive Insight Scale (BCIS) total (p = 0.026) and self-certainty (p = 0.035) and dependence self-subscale of irrational beliefs, comparing baseline and post-treatment. Moreover, comparing baseline and follow-up, the MCT group was better than the psycho-educational group in self-reflectiveness on the BCIS (p = 0.047), total BCIS (p = 0.045), and intolerance to frustration (p = 0.014). Jumping to Conclusions (JTC) improved more in the MCT group than the psycho-educational group (p = 0.021). Regarding the comparison within each group, Theory of Mind (ToM), Personalizing Bias, and other subscales of irrational beliefs improved in the MCT group but not the psycho-educational group (p < 0.001-0.032). CONCLUSIONS MCT could be an effective psychological intervention for people with recent onset of psychosis in order to improve cognitive insight, JTC, and tolerance to frustration. It seems that MCT could be useful to improve symptoms, ToM, and personalizing bias.

Abstract
IntroductionErotomania (“Clérambault's syndrome”) is a rare syndrome characterized by a delusional belief of being loved by another person, usually of higher social status.ObjectiveThis case report aims to describe and discuss a case of erotomania, providing an updated review on this disorder.MethodsRegular clinical interviews were performed during admission period to collect information about the clinical case and to promote an intervention approach to the patient. A literature review in Science Direct database, with the keyword “erotomania”, was also conducted.ResultsA 51-year-old woman was admitted in Beatriz Ângelo Hospital psychiatric ward with delusional beliefs of being loved by the ex-boss. Positive misperceptions and persecutory delusions regarding her husband as the obstacle for the love were manifested. The lack of insight for the situation and the necessity of treatment created some difficulties. A clinical report and a bibliographic review were made to allow a better understanding about the case and to orient the case evidence based.ConclusionsDespite the evidence about the good response of atypical antipsychotics (e.g. risperidone) in erotomania, in our case study, the partial remission was only achieved with high dose of the old typical antipsychotic, pimozide.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
KEY POINTS Patients with chronic kidney disease have a higher risk of developing cardiovascular diseases than the general population. Their vascular endothelium is dysfunctional, among other things, because it is permanently exposed to uraemic toxins, several of which have poor clearance by conventional dialysis. Recent studies have demonstrated the important role of integrin-linked kinase (ILK) in the maintenance of endothelial integrity and in this study we investigate the involvement of ILK in the mechanism underlying vascular endothelial damage that occurs in uraemia. For the first time, we demonstrate the implication of ILK in the protection against endothelial cell damage (inhibition of proliferation, toxicity, oxidative stress and programed cell death) induced by uraemic serum from chronic kidney disease patients and uraemic toxins. This molecular mechanism may have clinical relevance because it highlights the importance of maintaining high levels of ILK activity to help preserve endothelial integrity, at least in early stages of chronic kidney disease. ABSTRACT Patients with chronic kidney disease (CKD) have a higher risk of developing cardiovascular diseases. Their vascular endothelium is dysfunctional, among other things, because it is permanently exposed to uraemic toxins, several of which, mostly protein-bound compounds such as indoxyl sulfate (IS) and p-cresyl sulphate, having poor clearance by conventional dialysis, induce endothelial toxicity. However, the molecular mechanism by which uraemic toxins regulate early stages of endothelial dysfunction remains unclear. Recent studies have demonstrated the important role of integrin-linked kinase (ILK) in the maintenance of endothelial integrity. In this study, we investigate the involvement of ILK in the mechanism underlying vascular endothelial damage that occurs in uraemia. First, we show that incubation of EA.hy926 cells with human uraemic serum from CKD patients upregulates ILK activity. This ILK activation also occurs when the cells are exposed to IS (25-100 μg ml(-1)), p-cresol (10-100 μg ml(-1)) or both combined, compared to human serum control. Next, we observed that high doses of both toxins together induce a slight decrease in cell proliferation and increase apoptosis and reactive oxygen species production. Interestingly, these toxic effects displayed a strong increase when the ILK protein is knocked down by small interfering RNA, even at low doses of uraemic toxins. Abrogation of AKT has demonstrated the ILK/AKT signalling pathway involved in these processes. This study has demonstrated the implication of ILK in the protection against endothelial cell damage induced by uraemic toxins, a molecular mechanism that could play a protective role in the early stages of endothelial dysfunction observed in uraemic patients.

Abstract
Transforming growth factor type-β1 (TGF-β1) has been recognized as a central mediator in many pathological events related to extracellular matrix (ECM) proteins accumulation, where their locally increased expression has been implicated in the fibrosis process of numerous organs, including glomerular fibrosis in the kidney. We and others have reported the TGF-β1 synthesis regulation by reactive oxygen species (ROS), and moreover we also described the implication of integrin-linked kinase (ILK) in the AP-1-dependent TGF-β1 up-regulation. Thus, we propose here that hydrogen peroxide (H2O2)-dependent TGF-β1 regulation may be mediated by ILK activation. First we confirmed the increase in TGF-β1 expression in human mesangial cells (HMC) after treatment with H2O2 or with an alternative H2O2-generating system such as the glucose-oxidase enzyme (GOX). By using immunoblotting, immunofluorescence, and ELISA techniques, we demonstrate that extracellular H2O2 up-regulates TGF-β1 transcription, as well as increases TGF-β1 promoter activity. Furthermore, catalase-decreased intracellular H2O2 abolished TGF-β1 up-regulation. The use of pharmacological inhibitors as well as knockdown of ILK with small interfering RNA (siRNA) demonstrated the implication of a PI3K/ILK/AKT/ERK MAPK signaling pathway axis in the H2O2-induced TGF-β1 overexpression. Finally, we explored the physiological relevance of these findings by treating HMC with angiotensin II, a known stimuli of H2O2 synthesis. Our results confirm the relevance of previous findings after a more physiological stimulus. In summary, our results provide evidence that ILK activity changes may act as a mechanism in response to different stimuli such as H2O2 in the induced TGF-β1 up-regulation in pathological or even physiological conditions.

Abstract
Glomerular diseases are characterized by a sustained synthesis and accumulation of abnormal extracellular matrix proteins, such as collagen type I. The extracellular matrix transmits information to cells through interactions with membrane components, which directly activate many intracellular signaling events. Moreover, accumulating evidence suggests that eicosanoids derived from cyclooxygenase (COX)-2 participate in a number of pathological processes in immune-mediated renal diseases, and it is known that protein kinase B (AKT) may act through different transcription factors in the regulation of the COX-2 promoter. The present results show that progressive accumulation of collagen I in the extracellular medium induces a significant increase of COX-2 expression in human mesangial cells, resulting in an enhancement in PGE2 production. COX-2 overexpression is due to increased COX-2 mRNA levels. The study of the mechanism implicated in COX-2 upregulation by collagen I showed focal adhesion kinase (FAK) activation. Furthermore, we observed that the activation of the phosphatidylinositol 3-kinase (PI3K)/AKT pathway by collagen I and collagen I-induced COX-2 overexpression was abolished by PI3K and AKT inhibitors. Additionally, we showed that the cAMP response element (CRE) transcription factor is implicated. Finally, we studied COX-2 expression in an animal model, NG-nitro-l-arginine methyl ester hypertensive rats. In renal tissue and vascular walls, COX-2 and collagen type I content were upregulated. In summary, our results provide evidence that collagen type I increases COX-2 expression via the FAK/PI3K/AKT/cAMP response element binding protein signaling pathway.

Abstract
The nitric oxide (NO)-soluble guanylate cyclase (sGC) pathway exerts most of its cellular actions through the activation of the cGMP-dependent protein kinase (PKG). Accumulation of extracellular matrix is one of the main structural changes in pathological conditions characterized by a decreased activity of this pathway, such as hypertension, diabetes, or aging, and it is a well-known fact that extracellular matrix proteins modulate cell phenotype through the interaction with membrane receptors such as integrins. The objectives of this study were 1) to evaluate whether extracellular matrix proteins, particularly fibronectin (FN), modulate PKG expression in contractile cells, 2) to analyze the mechanisms involved, and 3) to evaluate the functional consequences. FN increased type I PKG (PKG-I) protein content in human mesangial cells, an effect dependent on the interaction with β(1)-integrin. The FN upregulation of PKG-I protein content was due to increased mRNA expression, determined by augmented transcriptional activity of the PKG-I promoter region. Akt and the transcription factor CCAAT enhancer-binding protein (C/EBP) mediated the genesis of these changes. FN also increased PKG-I in another type of contractile cell, rat vascular smooth muscle cells (RVSMC). Tirofiban, a pharmacological analog of FN, increased PKG-I protein content in RVSMC and rat aortic walls and magnified the hypotensive effect of dibutyryl cGMP in conscious Wistar rats. The present results provide evidence of a mechanism able to increase PKG-I protein content in contractile cells. Elucidation of this novel mechanism provides a rationale for future pharmacotherapy in certain vascular diseases.

Abstract
BACKGROUND Essential tremor (ET) is a frequent movement disorder with a substantial family aggregation. A genome-wide association study has recently shown that LINGO1 gene variants are associated with increased risk of ET. METHODS We intended to replicate these findings by genotyping rs9652490 and rs11856808 in a series of 226 familial ET subjects and 1117 healthy controls from referral movement disorder clinics in Spain. RESULTS We were unable to replicate the association between LINGO1 variants and familial ET. CONCLUSIONS Our results indicate that the LINGO1 variants analyzed are not a major risk factor for developing familial ET in our population, which suggests the existence of other unknown genetic risk factors responsible for familial ET in the Spanish population.

Abstract
The efficacy of electroconvulsive therapy (ECT) is widely recognized and indications are well defined for acute treatments. Surprisingly, the use of continuation and maintenance ECT (M-ECT) is uncommon after acute remission. This is partly because of the scarcity of scientific evidence. Indications are poorly defined and the practice is based on case reports and small open studies. Recent data suggest that M-ECT is a viable treatment option in severe affective and psychotic illnesses, especially in recurring, drug-resistant or medically compromised patients who suffer toxic effects with psychotropics.Studies regarding the duration and frequency of treatment sessions are laking. The time interval between sessions and duration of treatment vary according to clinical requirements, and should be individualized. The length of treatment and deciding when to stop it are still uncertain. Controversial data about the relation between the frequency of sessions and diagnostic is found. An inverse relation between good prognostic factors for each patient and the frequency of M-ECT was described. During continuation and maintenance ECT, seizure threshold increases until a plateau not being clear when the plateau is reached and if it depends on other treatment variables.The risk of cognitive dysfunction following M-ECT is one major concern. A transient memory and attention dysfunction are described after acute ECT. Recent studies seem to suggest that M-ECT is cognitively safe.

Abstract
During a period of 42 months, we studied the prevalence of epilepsy in a specific health district, composing by four towns with 98,405 inhabitants older than 10 years. This has been accomplished by a two-phase cross-sectional study. The prevalence rate observed was 4.12/1000 inhabitants for all types of epilepsy. No significant differences were found between the sexes. Sixty-three per cent of affected individuals had partial seizures, with a confirmed cause in 45%. Fifty-five patients with single unprovoked seizures, were also identified but not included in the prevalence rate.

Abstract
AIMS To analyse the influence of thyroid hormones on serum lipoprotein(a) (Lp(a)) concentration and other lipid parameters, and hence potentially on coronary artery disease (CAD) risk. METHODS Thirty-six patients with hypothyroidism and 165 age-matched control euthyroid subjects were evaluated in a cross- sectional study, determining thyroid function tests and fasting serum lipids and lipoproteins. In a follow-up study for those hypothyroid patients the same determinations were repeated after normalization of thyroid state by levothyroxine (L-T(4)) replacement therapy. Patients needing other treatments were excluded. At baseline, patients with hypothyroidism had significantly higher levels of Lp(a), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), apolipoprotein (apo) A-I and apo B, and a higher TC/high-density lipoprotein cholesterol (HDL-C) ratio than control subjects. RESULTS Severity of the hypothyroid state, expressed by serum thyroid-stimulating hormone, was correlated with serum levels of Lp(a), LDL-C, and TC (r= 0.64, 0.52, 0.49, P= 0.005, P= 0.033, P= 0. 048, respectively). The pretreatment Lp(a) levels were also correlated with those of posttreatment Lp(a)(r= 0.68, P= 0.002). All patients, who presented basal Lp(a) levels higher than 30 mg/dl, showed a decrease in Lp(a) concentrations by L-T(4)therapy, and these normalized in eight cases (22.2%). Euthyroid state gave rise to a significant reduction of serum Lp(a) by 32.3%, of LDL-C by 22. 8%, of TC by 17%, of apo A-I by 9.6%, and of apo B by 9.3%. After L-T(4)therapy, CAD risk, expressed as TC/HDL-C ratio, decreased by 19.9%. CONCLUSIONS These results show that hypothyroidism is associated not only with elevated serum levels of LDL-C but also with elevated serum Lp(a) concentrations. Lp(a) levels may be at least partially modulated by thyroid hormone-dependent mechanisms, thus increasing the risk of developing premature atherosclerosis in hypothyroid state, that might be reduced by L-T(4)therapy.

Abstract
INTRODUCTION Sensory neuropathy is a clinical entity which has been considered to be found in relation to neoplasia, Sjogren's syndrome, long-term pyridoxine treatment, or to be idiopathic. CLINICAL CASE We present the case of a 33 year old woman who developed acute sensory neuropathy after being diagnosed as having varicella. She had no previous history of weight loss or other signs of neoplasia, no dryness of the mucous membranes or history of arthritis and had taken no toxic substances or pyridoxine, thus ruling out other causes of sensory neuropathy. The acute varicella infection was apparent from the clinical characteristics and the presence of specific IgM in serum. CONCLUSION The clinical signs, in the absence of other circumstances which might have been related, together with the presence of acute varicella-zoster virus infection seems to indicate that the two conditions were related.

Abstract
OBJECTIVE To determine the frequency and the linkage distribution of seven mutations at the polymorphic gene coding for the arylamine N-acetyl transferase (NAT2; EC 2.3.1.5) in 121 unrelated patients with sporadic PD and in 121 unrelated healthy volunteers. METHODS The study was performed with mutation-specific PCR using genomic DNA obtained from blood of the probands. RESULTS Comparison of the NAT2 genotypes of the overall PD patients and control subjects did not indicate statistically significant differences. However, patients with early-onset PD (onset before the age of 50 years, n=37) showed a higher frequency of slow-acetylation genotypes (78.4% patients) compared with both healthy control subjects (55.4%) and with late-onset (onset after 51 years of age, n=84) PD patients (54.8%). Such a difference was statistically significant (p < 0.015) and was the result of a homogeneous increase in the frequency of slow-acetylation alleles. All subgroups analyzed in the study were in Hardy-Weinberg equilibrium for mutations at the NAT2 gene. CONCLUSIONS Slow-acetylation-mutated alleles may be considered low-penetrance genes in early-onset PD pathogenesis, with a relative risk ratio for individuals with slow-acetylation genotype of 2.92 (95% CI, 1.26 to 6.78). This study provides evidence for the interaction of genetic and environmental factors in the etiology of sporadic PD.

Abstract
The problems posed by health care are related to health service structure and development. The transformation of a three level care structure into one of just two levels, primary care and specialized care, plays its part. With the aim of analyzing the importance these factors might have in present-day health care, we carried out an aleatoric study of all those patients who attended our neurological service in the years 1992 and 1993. We obtained two sample groups consisting of 921 and 849 patients respectively through interconsultatory requests from practitioners within a limited health care area. We studied the patient's background, the requesting practitioner, diagnosis obtained and complementary tests used. Patients from individual practitioners varied in number from 4 to 38, with some 20% of all patients having been referred by just six practitioners. 20% of the patients we studied showed no neurological pathology. Complementary tests used in all diagnoses sent to us amounted to less than half the number of patients studied. We analyzed the importance these factors have in the present delay in health care services.

Abstract
The frequency of five cytochrome P450IID6 allelic variants was studied in deoxyribonucleic acid from 123 patients with Parkinson's disease and 150 healthy volunteers. This was achieved by the use of mutation-specific polymerase chain reaction and restriction fragment length polymorphism. The analyses of the CYP2D6 genotype revealed no evidence for a higher prevalence of poor metabolizers among patients with Parkinson's disease. However, increased frequency of patients with Parkinson's disease with the genotype CYP2D6wt/CYP2D6B was observed. This is attributable exclusively to subjects with early onset of the disease (28 to 49 years), with a relative risk ratio of 4.16 (95% confidence limits, 2.0 to 8.3; p < 0.0005). The subjects who had late-onset Parkinson's disease (> or = 50 years) had genotypes and CYP2D6 allele frequencies similar to the healthy subjects. This indicates that the oxidative polymorphism is related to early-onset but not to late-onset Parkinson's disease. A different influence of CYP2D6 genotype on the risk of development of Parkinson's disease is observed in Spaniards, compared with previous findings in British subjects. These results suggest the combined effect of environmental toxins and CYP2D6 in the cause of Parkinson's disease.

Abstract
Human and Dark Agouti rat liver microsomes were analyzed for caffeine metabolism focusing on demethylase activity by using a simplified isocratic HPLC method. Results showed that, despite interspecies quantitative and qualitative differences on caffeine metabolism, mainly demethylated caffeine metabolites were detected in both species. Humans showed interindividual quantitative differences in caffeine demethylase activity in contrast to rats and, in both cases, the proportion of metabolites remained constant. In addition, aminopyrine N-demethylase activity was assayed, showing a direct correlation with caffeine demethylase activity in humans (r = 0.71) that is reported here for the first time, but not in rats (r = 0.21). These results indicate that, in human liver microsomes, caffeine and aminopyrine could be demethylated by the same or by closely related enzymes; whereas in Dark Agouti rats, there is no apparent relation between caffeine and aminopyrine demethylation pathways.

Abstract
Aminopyrine N-demethylase activity and the contents of cytochrome P-450, cytochrome b5, and NADPH-reductase activity in human liver microsomes from 31 different patients were studied. Our results show the existence of significant interindividual, but not sex- or age-related differences in N-demethylase activity (ranging between 0.52 and 4.42 nmol/min/mg protein), and that these differences are directly correlated with the content of cytochrome P-450 and NADPH-reductase activity, but not with that of cytochrome b5 content, in the samples. In contrast, no differences were found in the Michaelis-Menten constant values for aminopyrine (mean, 2.4 mmol/L) or NADPH (mean, 69 mumol/L), strongly suggesting that interindividual differences could be due to the occurrence of different amounts of the same enzyme, rather than the presence of different enzymes, in the population studied.
