The relationship of anxiety, comorbid

The relationship of anxiety, comorbid medical illness, and executive dysfunction to TRLLD Literature reviews have suggested that anxiety, medical illness, and executive dysfunction may be key clinical predictors of treatment resistance in LLD.37,45 Anxiety Anxiety is a common cotraveler with LLD. Several studies have found an increased time to remission, and reduced remission

rate, in LLD when Inhibitors,research,lifescience,medical there are either high levels of anxiety symptoms46-52 or a comorbid anxiety disorder such as generalized anxiety.53 Despite numerous studies establishing anxiety as a predictor of treatment resistance in LLD, this relationship is poorly understood. Mechanisms that may explain this relation-ship include reduced tolerance of, and adherence to, medication, or a more severe subtype of depression. Anxiety in late life is multidimensional, encompassing

worry, panic/fear, Inhibitors,research,lifescience,medical somatization, and personality factors54; the differential impact, of these dimensions on treatment resistance is largely unstudied. Along these lines, we have Inhibitors,research,lifescience,medical found preliminarily that symptoms of worry, and not fear or panic, predict both poor short-term outcome in LLD and poor long-term stability of remission (Andreescu C, personal communication, 2008). Needed is a treatment trial incorporating examinations of these multiple dimensions that will shed light on the anxiety-depression interface in late life. Medical burden Several studies have demonstrated that LLD patients with greater medical burden have a lower, and slower, treatment response in LLD (eg, refs 55-57). Although some studies have not supported a link between medical burden and treatment outcome,58,59 our group found

that greater medical burden predicted poorer Inhibitors,research,lifescience,medical acute outcome to antidepressant augmentation (primarily Inhibitors,research,lifescience,medical with bupropion or nortriptyline40) and poorer maintenance outcomes.60 One reason may be that medical illnesses seen in patients with LLD (eg, hypertension, high cholesterol, diabetes, endocrinologie disease) induce pharmacodynamic or structural central nervous system changes that reduce the efficacy Cilengitide of standard antidepressants. Other possibilities are that medical burden interferes with antidepressant adherence and/or increases variability of drug exposure, thus reducing the impact of antidepressants. Impairment of executive Cabozantinib XL184 functioning Neuropsychological impairment, particularly in executive functioning, is common and clinically significant in LLD.61 Several studies have noted a relationship of cognitive impairment, with lower antidepressant response rates,62-64 though other studies have not found this relationship.65-67 The discrepancy may result, from the variability between studies in measuring executive functioning, and the current consensus in the field is that executive dysfunction is associated with poorer LLD treatment outcomes with antidepressants.

Background: Otitis media with effusion is one of the leading

causes of hearing loss in children. Effective treatment of effusion in the middle ear requires appropriate empirical treatment and characterization of responsible pathogens. Objective of the present study was to detect pathogens in clinical samples from patients with otitis media with effusion in our area and Inhibitors,research,lifescience,medical to determine the sensitivity profile of isolated organisms to commonly used antibiotics. Methods: Sixty three samples of middle ear effusion were aseptically obtained from 36 children, Inhibitors,research,lifescience,medical who had been treated up to at least two weeks before sampling. They were analyzed using standard bacteriological and multiplex polymerase chain reaction (PCR) assays. Antibiotic susceptibility tests were also performed. Results: PCR analysis Inhibitors,research,lifescience,medical showed that DNA of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis were present in 60 (95.2%) of the samples. The culture-positive effusion for Streptococcus

Pneumoniae, HaemophilusInfluenzae and Moraxella catarrhalis was 34.9%. Almost all sellekchem isolates of Streptococcus pneumoniaee were sensitive to ciprofloxacin and Inhibitors,research,lifescience,medical erythromycin, and none of them was sensitive to co-trimoxazole. None of H. Influenzae isolates was sensitive to erythromycin, cefixim, co-trimoxazole, ampicillin and amoxicillin. None of M. Catarrhalis isolates was sensitive to ceftriaxone, co-trimoxazole, ampicillin and amoxicillin. Conclusion: Compared with other studies using PCR method, the number of H. influenza isolates was in higher in the present study (95.2%). Antibiotic sensitivity profiles of pathogens isolated in this study were different from others. Thus, we can determine empirical Cilengitide antibiotic therapy based on sensitivity profile in our geographic area. Key Words: Otitis media with effusion, polymerase chain reaction, antibacterial resistance, Iran, antibiogram Introduction Otitis media (OM) is a generic term for any inflammatory process in the middle ear cleft behind an intact tympanic membrane (TM). Otitis media with effusion (OME) indicates collection of fluid into middle ear without any sign of acute inflammation.

25 Two of the pathways act to regulate output from frontal cortex

25 Two of the pathways act to regulate output from frontal cortex to insure appropriate behavioral responses to stimuli.25 The “direct” pathway facilitates thalamic stimulation of the cortex. The “indirect” pathway acts to inhibit the thalamus – thus permitting the cortex to shift sets and respond to novel stimuli. OCD may result from excessive neural tone in the direct pathway Inhibitors,research,lifescience,medical relative to the indirect pathway. Neuroimaging studies of pediatric OCD Below is a brief review

of neuroimaging studies of pediatric OCD. The aim is provide enough background to highlight the move to a translational approach from an investigative one. Reports relevant to the translational research approach are in the following section. Frontal cortex Rosenberg et al31 did not find any significant difference in prefrontal

cortex (PFC) volume between pediatric OCD patients and age- and sex-matched Inhibitors,research,lifescience,medical controls. However, the measurement of total PFC volume may have been too gross a measure, and more subtle abnormalities in specific subregions lost. Indeed, the genu of the corpus callosum, which connects aspects of PFC across the hemispheres, was found to be larger in pediatric OCD subjects.32 Larger anterior cingulate volumes were also noted, consonant Inhibitors,research,lifescience,medical with the larger genu finding.33 Anterior cingulate volume was correlated with OCD symptom severity (r=0.73, obsessive subscale). This was replicated in a second sample.34 This is noteworthy as replication is rare in psychiatric research. Developmentally, the normal increase in anterior cingulate volume with age (r=0.45) was absent in patients with OCD (r=-0.12). Rosenberg and Keshavan33 hypothesized that increased anterior cingulate volumes correlating with reduced basal ganglia volumes (r=-0.46) in pediatric patients with Inhibitors,research,lifescience,medical OCD is

suggestive of neural network dysplasia Inhibitors,research,lifescience,medical – characterized by alterations in postnatal pruning. Developmentally, the greater anterior cingulate volume and lack of a correlation with age in pediatric patients with OCD may reflect delayed or reduced neural pruning, while reduced striatal volume might reflect increased pruning. No differences in posterior cingulate or dorsolateral prefrontal Brefeldin_A cortex (DLPFC) volume were noted.33 Subcortical and other regions Smaller basal ganglia volumes have been reported in treatment-naïve pediatric OCD patients.31 Furthermore, greater ventricular brain ratios have been observed in adolescent patients with OCD compared with healthy controls, which would be expected with decreased basal ganglia volume.35 The thalamus was found to be larger in pediatric OCD patients as compared with controls, a difference that resolved with SSRI learn more treatment36 but not cell differentiation cognitive behavioral therapy37 Also in the thalamus, greater medial but not lateral thalamic choline was observed in pediatric patients with OCD compared with both healthy controls and patients with major depressive disorder (MDD).

This new definition indicates the key role that the deletion tas

This new definition indicates the key role that the deletion task plays in the difference between the new generalized approach and the initial MCS concept. The deletion task can be specified by several Boolean rules that clearly represent and describe, unambiguously, the flux patterns or the functionality to be repressed. This increases the practical applicability of MCSs because they can now be determined for a large variety of complex deletion problems and for inhibiting very special flux patterns instead of just for studying structural fragility and kinase inhibitor Calcitriol identifying knock-out strategies. The refinements and extensions Inhibitors,research,lifescience,medical to the initial MCS concept offer a broader range of possible ways

in which MCSs can be used to assess,

manipulate and design biochemical networks. A comparison of the concept versions is covered later. 2.6. Further those refined Concept of MCSs Further refinement of MCSs has also been undertaken [15] to deal with their limitation of disabling desired functionalities along with the targeted ones. To address this limitation, Inhibitors,research,lifescience,medical Hädicke and Klamt [15] generalized MCSs to Constrained MCSs (cMCSs) that take into consideration side constraints and allow for a set of desired modes, with a minimum number preserved, to be defined. This generalization provides a flexibility for cMCSs to be applied to existing methods, for example Minimal Metabolic Functionalities Inhibitors,research,lifescience,medical [25,26], OptKnock [27], and RobustKnock

[28] can be reformulated as special cases of cMCSs. As demonstrated in [15], the cMCSs approach offers great flexibility in defining Inhibitors,research,lifescience,medical and solving knock out problems. The next section compares the three concepts, to get a better understanding of MCSs and how they have developed. 2.7. Comparing MCS Concepts 2.7.1. Same Properties Some properties between the initial and generalized/ refined concepts of MCSs remain the same. For example: there will always be a trivial MCS- the objective reaction itself; Inhibitors,research,lifescience,medical some reactions such as the biomass synthesis, are actually pseudo-reactions that are not related to a single gene or enzyme and thus cannot be repressed by inhibitions such as gene deletions; the definition of Cilengitide the MCSs: each MCS provides a minimal (irreducible) set of deletions or EMs from the set of target modes, that will achieve the elimination of the objective reaction. 2.7.2. Different Properties A deletion task T is a set of constraints that characterize the stationary flux patterns (reactions) r to be repressed while D, derived from T, characterizes the target modes (EMs) to be targeted by MCSs. As such, D (for the target modes) and T (for the flux vectors r) are, in most cases such as in the earlier MCS concept, identical. In the generalized MCS concept, however, the deletion task D can either differ from T or T must be transformed into several Di that lead to sub-tasks.

Evidence for IDO in depression is supported bystudies demonstrati

Evidence for IDO in depression is supported bystudies demonstrating that decreased levels of tryptophan and increased kyneurenin is associated with inflammation and depression.185 Increased IDO has also been positively correlated with depression, although a direct causal relationship has not been demonstrated. A recent study has now provided direct evidence that induction of IDO underlies the depressive behaviors caused by inflammation/activated immunologic conditions. This work was conducted using a bacterial immune activation model, Bacille Calmette-Guerin (BCM), which induces a long-lasting induction of interferon

and results in depressive behaviors in animal models.185,186 The results Inhibitors,research,lifescience,medical demonstrate that BCM-mediated immobility in the forced swim test is reversed by an IDO inhibitor, 1-methyltryptophan, and in mice that are deficient in IDO.185 In addition, BCM also increases the expression of a downstream enzyme, Inhibitors,research,lifescience,medical 3-hydroxyanthranilic acid oxygenase (3-HAO) that is involved in the synthesis of quinolinic acid. These studies indicate that an IDO inhibitor, and possibly an inhibitor of 3-HAO, could have efficacy for the treatment of depression and related mood disorders. Summary and future directions Significant advances have been made in characterizing the neuronal and glial damage, or structural Inhibitors,research,lifescience,medical alterations, at the cellular and anatomical levels in stress-related mood disorders and

other psychiatric illnesses, and in elucidating the molecular signaling MG132 proteasome pathways and mechanisms that underlie these changes. However, this work Inhibitors,research,lifescience,medical is still at a relatively early stage, and a more complete characterization of these complex alterations and signaling mechanisms will require extensive resources and time. Moreover, identification of genetic polymorphisms that impact these pathways and systems and that influence Inhibitors,research,lifescience,medical susceptibility or resilience to illness is a major area of research that will continue to develop and unfold. When ZD1839 combined with studies of environmental risk factors and lifetime history

of stress, this work will define and describe the mechanisms underlying individual variations of illness. Together, the results of this Brefeldin_A work can be used to formulate a comprehensive approach for the prevention and treatment of psychiatric illnesses. Changes in lifestyle and behavior can reduce stress and exposure to environmental factors that influence cellular risk and damage and prevent illness. These approaches, as well as behavioral interventions that enhance the activity and function of specific neural circuits, and thereby provide protection, can also be used once a person has become ill. Development of therapeutic agents that target neuroprotective mechanisms, combined with genetic information will ultimately provide tailored approaches for highly specific and efficacious treatments for depression and other illnesses.

We further postulate that the type of mutation, including point, substitution, deletion, or deletion-insertion, may affect clinical aggressiveness and prognosis, as well as response to imatinib and sunitinib, with exon 11 deletions having a more aggressive course. Additional research is needed to elucidate the relationship between the type of mutant genotypes, and the site of metastases, clinical aggressiveness, and response to tyrosine kinase inhibitors.

Gastric cancer is one of the most challenging diseases among all cancer types. It is the fourth most common Inhibitors,research,lifescience,medical cancer worldwide, with an estimated 934 000 new cases

per year in 2002 (9% of new cases globally), and occurs nearly twice as often in Inhibitors,research,lifescience,medical men (1). In the United States, mortality due to gastric cancer has declined and five-year relative survival rates improved from 16% to 24% between 1975 and 2002 (2). In Turkey, gastric cancer is the second leading cause of death in men and the third leading cause of cancer mortality in women (3). The anatomical site of origin of gastric cancer among Turkish patients differs Inhibitors,research,lifescience,medical from that reported for Western countries, with 48.1% and 41.2% of

cancers in Turkish patients occurring at the antrum and corpus, respectively, and 51.6% of patients having a pathological grade III cancer (4). Surgery is the main treatment modality for gastric cancer. Only in Japan, the majority of patients are surgically treated at stage I (5). The reported median survival benefit in AGC patients receiving chemotherapy is approximately 6 months (6), and the reported benefits of novel chemotherapy regimens for AGC have been shown to not exceed 12 Inhibitors,research,lifescience,medical months in recent Phase III trials in Western countries (7),(8). Fluorouracil-(5-FU) based chemotherapies are the mainstay of treatment for AGC. Since continuous 5-FU infusion has shown promising results in the treatment of AGC in Phase II trials, combination therapies have been Inhibitors,research,lifescience,medical developed (9). Oral fluoropyrimidines are the best alternative to infusional 5-FU in three-drug regimens for AGC. Tegafur (UFT) is an oral fluoropyrimidine and

its antitumor activity is known to generate plasma 5-FU levels that are similar to those of Anacetrapib infusional 5-FU (10)-(12). This pilot study was conducted to examine the safety and toxicity of combination chemotherapy consisting of epirubicin, cisplatin, and UFT regimen in chemo-naïve AGC outpatients. Patients and methods Patients Forty-one AGC patients who admitted to Istanbul University Oncology Institute between September 2003 and December 2006 were included in this study. Patients with histologically or surgically proven metastatic or locally advanced inoperable gastric carcinoma were eligible. They were required to have a performance status (PS) level of (0) or (1) according to WHO criteria. There was no age limit.

Insulin shock therapy was used fairly commonly until the mid-1980

Insulin shock selleck chem therapy was used fairly commonly until the mid-1980s, but is now largely outdated.40 Though decreasing in use, Chinese clinicians still administer electroconvulsive shock therapy (ECT) (usually without anesthesia) to schizophrenic

patients more frequently (21% in one sample)35 than their Western counterparts; they consider ECT particularly helpful for agitated patients and for hastening the recovery of patients taking antipsychotic medication, a belief that is also held by clinicians in other developing countries.41 Almost all acute-care wards in Chinese psychiatric hospitals arc single -sex locked wards in which patients wear hospital garb, so psychosocial interventions are important in preventing Inhibitors,research,lifescience,medical the Inhibitors,research,lifescience,medical sensory deprivation that often accompanies hospitalization. In some small, understaffed hospitals, acute-care patients spend most of their time sitting in their rooms with nothing to do, while in the larger well-staffed hospitals they participate in a wide variety of activities, such as calligraphy classes, “music therapy”42 (listening to soothing music), and “work therapy” (typically monotonous Inhibitors,research,lifescience,medical tasks). Similarly, some chronic care wards are little more than warehouses for the severely mentally ill and the severely mentally retarded, but the better chronic care wards have an open-door policy,

allow patients to wear their own clothes, and provide a variety of structured activity programs.43,46 China has no occupational therapists or psychiatric social workers and the small number of psychologists working in psychiatric hospitals limit their function to psychological testing (rather

than providing clinical services); thus the psychosocial services that are available to inpatients arc thus provided primarily by doctors and Inhibitors,research,lifescience,medical nurses. Like everywhere else in the world, economic factors influence the treatment schizophrenic patients receive in China. Insured schizophrenic patients Inhibitors,research,lifescience,medical – primarily urban residents who work for government-supported industries – receive inpatient treatment 2.8 times more frequently than uninsured schizophrenic patients; the mean length of sellectchem hospitalization of insured patients is longer than that of uninsured Dacomitinib patients; insured inpatients are more likely to receive ancillary treatments such as TCM drugs; and insured inpatients are less likely to receive ECT.35 Outpatient treatment Almost all outpatient psychiatric services for schizophrenic patients are provided in the outpatient departments of psychiatric hospitals: there are very few freestanding community psychiatric clinics, the psychological clinics that have opened in some general hospitals over the last few years rarely provide services for schizophrenic patients, and the number of private psychiatrists (mostly physicians who have retired from the hospital system) is extremely small. ‘Ihe primary service provided in the outpatient clinics of psychiatric hospitals is medication monitoring.

Multiple miRNAs implicated in different aspects of cardiac develo

Multiple miRNAs implicated in different aspects of cardiac development To date, a wide range of miRNAs has been specifically implicated in different aspects of cardiovascular development. For example, miR-1, -133a, -133b, comprise a subset of skeletal- and cardiac-muscle specific

miRNAs that are induced during order Gambogic acid and regulate muscle differentiation (reviewed in 28,45,47 ). MiR-1 and miR-133 are two highly conserved miRNAs derived from a common precursor transcript, that exhibit cardiac- and skeletal- muscle specific expression during development and adult life. 46–47 According to studies, miR-1 (miR-1-1, mir-1-2) targets, amongst others, 46,54 the transcription factor (TF) Hand2, a promoter of ventricular cardiomyocyte expansion, whose levels are critical for normal cardiomyocyte morphogenesis and development. 46,48–52 Studies utilizing knockout mice of mir-1-2 have reported dysregulation of cardiac conduction, cell cycle and defective heart development in these animals, a subset of which suffered from early lethality, 53,54 thereby proposing a distinct role of miR-1-1 and mir-1-2 in cardiac development. MiR133a is also critical for cardiac development.

Interestingly, miR-133a-1 and miR-133a-2 present with at least partly overlapping roles, since the deletion of either one at a time results in phenotypically normal the mice. However, the double-mutant miR-133a mouse embryos and neonates present with ventricular-septal defects often leading to early lethality, whilst the surviving animals are prone to dilated cardiomyopathy and

heart failure. MiR-133a gene targets include Cyclin D2 and Serum Response Factor, the upregulation of which possibly underlies the dysregulation of cell cycle control and the aberrant activation of the smooth muscle gene program, as observed in miR-133a-1/ miR-133a-2 double mutant mice. 55 Cyclin D2 is also targeted by miR-29a, and this process has been shown to suppress cardiomyocyte proliferation during postnatal development in rats. 56 A recent global microRNA profiling study reported another miRNA, namely miR-27b, displaying a greatly elevated myocardial expression during heart development in mice. Interestingly, the TF Mef2c, which is involved in cardiac morphogenesis, was shown to be a target of miR-27b. 57 A series of studies in zebrafish has also provided valuable data for miRNAs implicated Cilengitide in heart development. For example, miR-23 has been shown to inhibit Hyaluronan synthase 2 (Has2) expression and extracellular hyaluronic acid production. 40 Has2 is an extracellular remodeling enzyme which is required for endocardial cushion and valve formation, and when inhibited by miR-23 the number of endocardial cells that differentiate into endocardial cushion cells during development in zebrafish embryos was restricted. 40 Endocardial cushions develop on the atrio-ventricular canal and play a role in proper heart septation during development.

11 This study is one of the first estimates provided for CG in the general population using clinical interviews. They found a prevalence of 4.8% for complicated grief disorder within the general population. Overall, 1089 participants were found to be currently experiencing grief. Of these, 277 were diagnosed with

CG, which equals a conditional prevalence of 25.4% in the population. Interestingly, while the authors report inflated rates for anxiety and depression in people with CG, comorbidity was not found for the vast majority of participants. As such, CG may be considered to be both a distinct disorder, but also Inhibitors,research,lifescience,medical as sellekchem existing along a continuum, rather than as a clear taxon.27 The highest Inhibitors,research,lifescience,medical prevalence rate was found to be in the 75- to 85-year-old age-group, with a rate of 7%, as compared to 4.8% for older adults overall. In Japan, an epidemiological screening study was recently conducted29 using a five-item scale that evaluated intrusions, avoidance, estrangement from others, trouble accepting the death, and interference of grief in daily life. Participants were 40 to 79 years old; however, the study included only participants who reported bereavement, which may Inhibitors,research,lifescience,medical be a bias because there are people in the general population

who do not report bereavement at all. The authors found what can be considered a conditional probability of 2.4% in that population. Both studies converged, despite methodological differences, on the finding that PGD patients are few in the general population. Furthermore, their number is age-dependent. Indeed, for biological reasons, Inhibitors,research,lifescience,medical older people are more likely to be affected by bereavement involving persons in their social network. Further threads in prolonged grief disorder research Proper research on a (new) psychological disorder must not focus

on diagnostics, assessment, prevention, and treatment alone. While these aspects of research are important, we argue that a core understanding and appreciation of the disorder must also be promoted. Inhibitors,research,lifescience,medical It should be noted that the recent edition of the Handbook of Bereavement: Research and Practice by M. S. Stroebe and colleagues30 provides a comprehensive collection of the major theories and impulses on these aspects. Stroebe and Shut31 proposed a systematic model of grief in general, the dual-process model in concordance with Rubin’s32 earlier two-track model of bereavement. They proposed that a loss-oriented process, Entinostat whereby self-confrontation or avoidance can provide alleviation, allowing an individual to rebuild their life, has to be distinguished from a restoration-oriented process, where the individual may cope with the loss by engaging in new relationships and tasks. According to the model, these two processes represent individual differences in terms of alternatives or individual styles used by different people but may, however, also occur within the same person as an oscillating process.

1A) The hanging mercury drop

1A). The hanging mercury drop electrode is periodically renewed (Figure 1A1). Target molecules are adsorbed on the surface of the renewed working electrode at an open circuit (Figure 1A2). The electrode is washed with a supporting electrolyte (Figure 1A3). The electrode with the adsorbed target molecules is measured in the presence of the supporting electrolyte (Figure 1A4).Figure 1.Scheme of adsorptive transfer technique (A). Typical voltammograms of 100 nM MT (solid red line), supporting electrolyte (dotted black line) (B).Brdicka reaction of MTMT was measured by AdTS coupled with a differential pulse voltammetry (DPV) Brdicka reaction. Brdicka supporting electrolyte (1 mM Co(NH3)6Cl3 and 1 M ammonia buffer (NH3(aq) + NH4Cl, pH = 9.6) was used without surface-active agent additives. AdTS DPV Brdicka reaction parameters were as follows: an initial potential of �C0.35 V, an end potential of �C1.8 V, a modulation time of 0.057 s, a time interval of 0.2 s, a step potential of 1.05 mV, a modulation amplitude of 250 mV, Eads = 0 V. Temperature of supporting electrolyte was 4 ��C.2.3. Clinical materialHuman blood serum samples from patients with breast cancer were obtained from the Department of Clinical Biochemistry and Pathobiochemistry, FN Motol, Prague, Czech Republic. The sampled sera were immediately frozen at �C20 ��C prior to their preparation. The sample was prepared by heat treatment followed by solvent precipitation. The samples were kept at 99 ��C in a thermomixer (Eppendorf 5430, USA) for 15 min. with occasional stirring, and then cooled to 4 ��C. The denatured not homogenates were centrifuged at 4 ��C, 15,000 g for 30 min. (Eppendorf 5402, USA). Heat treatment and solvent precipitation effectively denatured and removed high molecular weight proteins from the samples [19]. MT levels in the human blood serum samples were measured by AdTS DPV Brdicka reaction.2.4. Descriptive statisticsMicrosoft Excel? (USA) was used for mathematical analyses. Results are expressed as mean �� S.D. unless noted otherwise. The detection limits (3 S/N) were calculated according to Long [20], whereas N was expressed as standard deviation of noise determined in the signal domain.3.?Results and DiscussionProteomic research demands highly sensitive analytical instruments to detect very low volumes or amounts of a biological sample. Analysis is preferably carried out on the instruments to be low cost and easy to use, and, moreover, there is great demand on miniaturization of the instruments used [21-36]. The impact of these demands is well demonstrated in the field of flow microchips technology [37-52]. Electrochemical devices, methods and approaches have a valuable contribution to this field. In particular, the introduction of adsorptive transfer technique by Prof. Palecek was a great advancement in the electroanalysis of low volume samples [52-58].3.1.
