89. The BDI-II (Beck, Steer, & Brown, 1996) contains 21 statements that assess the severity of depressive symptoms such as low mood, anhedonia, changes in sleep, appetite, concentration, etc. over the preceding two weeks. Beck et al. (1996) report good internal consistency in both patient and student samples and one-week re-test-reliability of r = .93 suggesting that the test is robust against

daily variations in mood in depressed samples. The FFMQ (Baer et al., 2006) was developed based on factor analyzes of previously published Gemcitabine price mindfulness questionnaires. It assesses five facets of a general tendency to be mindful in daily life: observing (“I notice the smells and aromas of things”), describing (“I am good at finding words to describe my feelings”), acting with awareness (“I find myself doing things without paying Apoptosis inhibitor attention” – reverse scored), non-judging of inner experience (“I think

some of my emotions are bad or inappropriate and I should not feel them” – reverse scored), and non-reactivity to inner experience (“I perceive my feelings and emotions without having to react to them”). In line with the assumption that mindfulness has beneficial effects on emotional health, validation studies have reported negative correlations between the FFMQ (total and subscale scores) and self-report measures of emotional symptoms and distress as well as positive correlations with self-report measures of psychological well-being (Baer et al., 2008). Internal consistency of the subscales of the FFMQ in our sample was generally acceptable (see Table 1). Zero-order Cyclic nucleotide phosphodiesterase correlations showed that neuroticism scores assessed 6 years previously were correlated with the severity of current symptoms

of depression as assessed by BDI-II, r = .56, p < .001. The FFMQ total mindfulness score was inversely correlated with both neuroticism, r = −.60, p < .001, and severity of current symptoms of depression, r = −.58, p < .001. Correlations of the subscales of the FFMQ showed the same pattern of findings – significant inverse correlations with both neuroticism and current symptoms of depression – for all of the subscales apart from the “Observing” scale, which did not show a significant relation with either neuroticism or severity of current symptoms of depression. Correlation coefficients, means and standard deviations of raw scores and percent of maximum possible scores (POMP; Cohen, Cohen, Aiken, & West, 1999) on all scales are listed in Table 1. In order to investigate the effects of neuroticism and mindfulness on current symptoms of depression we conducted a linear regression. In the first step EPQ neuroticism was entered as predictor of BDI-II scores yielding a significant effect, t = 8.21, p < .001, β = .56, R2 = .32, ƒ2 = .47.

, 1996). Nowadays, this species has inhabited places with minimal vegetation and proliferated widely in urban areas, and can be easily found in boxes and networks of sewers, and storm sewers. Is considered parthenogenetic and ecologically opportunistic, with great dispersive fitness and high reproductive capacity ( Lourenço et al., 1996 and Brazil et al., 2009). Probably in the 1970s, this species was introduced in the Federal District in Brazil

(Distrito Federal, DF) during the occupancy of this region after the new Brazilian capital was built (Lourenço et al., 1994), the inhabitant population Apoptosis inhibitor in DF was 141,742, increasing to 537,492 in 1970, and to 2,570,160 in 2010 (http://www.ibge.gov.br/home/estatistica/populacao/censo2010/resultados_dou/DF2010.pdf). In the last decade (2000–2010), there were 1889 scorpion accidents in DF. Surprisingly, accidents caused by T. serrulatus in DF (Brazil) are considered

mild and symptoms such as acute pulmonary edema have not been reported ( Yoshizawa, 2002 and Sinan, 2013) while in Minas Gerais, a vicinal state, envenoming by this same species might be severe with reported deaths caused by acute lung edema ( Funasa, 2001 and Funasa, 2009). Given that, in the present work, we compared the toxicity and the edematogenic activity of T. serrulatus venoms www.selleckchem.com/products/iwr-1-endo.html obtained from animals captured in the states of DF and MG in Brazil, and the venom composition of both scorpion populations to understand the differences observed. Male Wistar rats (Rattus norvegicus),

weighting from 230 to 250 g and male Swiss mice (Mus musculus), from 18 to 20 g, were supplied by the vivarium facility of the Biological Sciences Institute, University of Brasilia (Brazil), where they were kept in cages, maintained under appropriate conditions and received commercial chow and water ad libitum. Specimens of T. serrulatus scorpions were collected in urban regions of Distrito Federal and the venom was extracted by electrical stimulation, Epothilone B (EPO906, Patupilone) resuspended in ultra-pure water and lyophilized. The T. serrulatus venom from urban regions of Minas Gerais was kindly provided by Dr. Consuelo Latorre Fortes-Dias from the Fundação Ezequiel Dias (FUNED, Belo Horizonte/MG), and was obtained by the same method. T. serrulatus venoms from Minas Gerais (Ts-MG) and from Distrito Federal (Ts-DF) were lyophilized, weighed dry, and diluted in saline (150 mM NaCl) prior to the assays. The LD50 of the T. serrulatus venom from two populations were determined as follows. Ts-MG venom was tested in doses of 5.8, 11.6, 17.4, 23.2, 34.8, 46.4, 58 and 72 μg/mouse of 20 g by i.p. injection (n = 8). The first tested dose was 23.2 μg/mouse based on the LD50 obtained by Nishikawa et al. (1994). Ts-DF venom was tested in doses of 14, 26, 36, 50, 60, 70, 80 e 90 μg/mouse of 20 g by i.p. injection (n = 8). The first tested dose was 50 μg/mouse, which corresponded to twice the calculated LD50 from Ts-MG.

Stroke Diagnosis Poster 167 A Clinical Assessment and Neuro-Imaging based Grading Scale Predicts Severe Post-Stroke Limb Spasticity. Wayne Feng (Medical University of South Carolina, Charleston, SC), Andrew Gundran, Ali Tabesh, Lindsay Perry, Madhura Athreya, Michelle Woodbury, Steven Kautz, Robert Adams Objective: The objective of this study is to identify find more a grading scale that can predict post-stroke limb spasticity from the acute phase. Design: This is a prospective cohort study of 47 patients with first-ever acute ischemic strokes and various degrees of motor impairment. The first assessment was done between 2 to 5 days after stroke with Fugl-Meyer upper extremity (FM_UE) scale, NIH Oxymatrine stroke scale and MRI of brain, the second assessment was completed at 3 months (+/- 2 weeks) with Modified Ashworth Spasticity Scale (MASS) at biceps, wrist and finger flexor. A highest value is used. Independent predictors of

severe spasticity (MASS is ≥3) were identified by logistic regression. A risk stratification scale was developed with weighting of independent predictors based on strength of association. Interventions: Observational study. Main Outcome Measures: MASS. Settings: Comprehensive stroke center. Participants: Ischemic stroke patients. Results: Factors independently associated with limb spasticity are motor function at baseline measured by FM_UE scale (P≤.0005), location of lesion (P=.002) and corticospinal tract (CST) lesion load (P<.03). The proposed grading scale is summation of individual points as followed: FM_UE Scale: >4(1 point), ≤4(0 point); Lesion location: subcortical or corti- cal (0 point), subcortical and cortical (1 point); CST lesion load: >7cc (1 point) ≤7cc (0 point). None of 22 patients (with score of 0) and all 7 patients (with score of 3) developed severe spasticity. The likelihood of developing severe spasticity in- creases steadily with grading scale score.

Although a switch from short-lived apoptosis prone B cells to lon

Although a switch from short-lived apoptosis prone B cells to longer-lived naïve and resting memory B cells was seen relatively early after initiation of ART, there were no significant changes observed in the

percentages and absolute numbers of total CD19+ B cells during ART in this cohort during the 12 months of observation. Some previous studies in children have shown no changes selleck chemicals llc in total CD19+ B cells during ART37 while other studies in both adults and children have shown rises.18, 38, 39 and 40 There are numerous factors that may differ between these samples which could have contributed to these discordant findings but the most immediate apparent need is to follow these trends over a longer observation period. We have previously demonstrated acquisition of pneumococcal protein-specific T cell and B cell immunity in both low carriage and high carriage populations.10, 41, 42, 43,

44 and 45 This naturally acquired immunity may occur as a result of multiple immunizing carriage events to a range of pneumococcal proteins expressed at the mucosal surface.46 In African children, pneumococcal nasopharyngeal carriage occurs very early in life and reaches very high rates47 and, as in this study, carriage rates may be higher among those with HIV infection.48 In this context, we have recently shown that even in minimally symptomatic HIV-infected children, pneumococcal protein antigen-specific memory B-cell numbers are low compared with HIV-uninfected children.10 The delayed recovery in pneumococcal antigen Sunitinib specific B cell memory after institution of ART that we describe here may indicate that these HIV-infected children remain both more vulnerable to invasive pneumococcal disease and to prolonged or higher density carriage. Understanding more clearly how B cell immune reconstitution relates to pneumococcal colonization will be important in countries such as Malawi

with high HIV prevalence and where Thiamine-diphosphate kinase pneumococcal conjugate vaccine (PCV) has recently been introduced into the routine infant immunization schedule, particularly since the effectiveness of these vaccines is to a great extent mediated by effects on carriage and transmission.49 Many of the children reported here were commenced on ART with a low percentage CD4 nadir (Fig. 1A). It is possible that the delayed and incomplete restoration of antigen-specific B cell function we observed would have been ameliorated by earlier initiation of ART.18, 50 and 51 This question has begun to be tackled programmatically as the thresholds for initiating ART are lowered but merits further investigation if vaccines are to be targeted effectively.

The objectives of the current study were (i) to determine the level of knowledge about influenza A(H1N1)pdm09 and self-protecting preventive behaviours for influenza Alectinib purchase A(H1N1)pdm09 and (ii) to identify the factors associated with the intention to receive the influenza A(H1N1)pdm09 vaccine among the study population. This study was a cross-sectional survey carried out in Mantin Town, which is a semi-urban area located in the Negeri Sembilan district of Malaysia. At the time of this study, 37,904 people lived in

Mantin Town, and the majority was Malay (57.9%), followed by Chinese (25.6%) [9]. One government clinic (Klinik Kesihatan Mantin) serves this population. A sample of 280 households GPCR Compound Library was selected for the present study. A structured questionnaire in English was prepared based on an extensive literature review and consultations with faculty members. The content of the questionnaire was validated through a series of consultations with content experts, including a clinical psychologist and an infectious disease epidemiologist. The questionnaire items were refined during pilot testing and translated from English into the local language. The questionnaire consisted of five domains: (i) sociodemographic characteristics, (ii)

knowledge of pandemic influenza symptoms (eight items), (iii) mode of transmission (five items), (iv) self-protecting preventive behaviours (five items), and (v) intention to receive the influenza A(H1N1)pdm09 vaccine. Face-to-face interviews were conducted using the interviewer-administered questionnaires in February 2010. The households interviewed were located within a 5-km radius of the Mantin public clinic (Klinik Kesihatan Mantin). The interviewers were undergraduate medical students enrolled in Semester 5 at the International Medical University (IMU) (i.e., the ME 1/08 cohort). These students

had been trained for 3 days in research methodology, including the administration of community-based surveys. Households were visited and asked to participate in a survey to collect information related to influenza A(H1N1)pdm09. The eligible participants were those who were the head of the household or any household member above 18 years old and those who were knowledgeable about the Rebamipide health and healthcare utilization of household members. The respondents were interviewed and instructed to answer yes/no, true/false or know/do not know, as appropriate. Verbal consent was obtained prior to beginning the interview. Confidentiality was also assured, and the interviewers did not record any personal identifier of the respondents. The respondents had the right to refuse to participate and to refuse to answer any question. The respondents’ answers were scored on a binary scale, with one point for any correct answer.

No grupo de 10 crianças/adolescentes com HAI, registaram-se 3 doentes do sexo masculino, não cumprindo o primeiro critério do score de diagnóstico 10. Em 2 crianças/adolescentes foi detetado outro tipo de doença de etiologia autoimune (AI): diagnóstico simultâneo de CU (caso 1) e diagnóstico prévio de trombocitopenia AI (caso 10). Em 2 doentes, a relação fosfatase alcalina (FA)/transaminases

foi superior a 3. Em 2 casos, não se verificou hipergamaglobulinemia. Em todos os doentes com HAI detetou-se, pelo menos, um dos auto-Acs habitualmente associados a esta patologia: ac anti-nuclear (ANA) – 8 (80%); ac anti-músculo liso (SMA) – 7 (70%), ac anti-microssoma hepático e renal (anti-LKM1) – 1 (10%). Os selleck inhibitor títulos variaram entre 1/40 e 1/1280. O caso 9 apresentava inicialmente títulos negativos que entretanto positivaram numa segunda amostra. Uma doente tinha ac anti-mitocondrial (AMA) positivo (caso 2), o que correspondeu a uma pontuação negativa no score de diagnóstico de HAI 10. Uma doente com ANA’s positivos, apresentava também dsDNA e SSA positivos (caso 5). Foram detetados outros tipos de auto-acs: ac anti-citoplasma dos neutrófilos (ANCA) em 2 doentes (20%), anti-citosol

hepático tipo 1 (anti-LC1) em um doente (10%) e anti-proteinase 3 num doente (10%). Em todas as crianças/adolescentes foram excluídas outras causas de doença hepática crónica. Verificou-se que todos os doentes apresentavam, pelo menos, uma das características histológicas típicas da HAI: hepatite de interface em 7 e infiltrado linfoplasmocitário em 9 – figura PD0325901 mouse 4. Um doente (caso 5) apresentava também lesão dos ductos biliares. Observou-se uma boa resposta ao tratamento imunossupressor em todos os doentes, tendo-se verificado recaída após a sua redução ou Interleukin-2 receptor suspensão em 6 casos. O somatório da pontuação de cada critério de diagnóstico correspondeu a um score de diagnóstico definitivo em 7 doentes e provável em 3. Após avaliação da resposta terapêutica aos imunossupressores o score de diagnóstico tornou-se

definitivo em todos os doentes. Em relação aos 7 doentes com CEP, verificou-se que um era do sexo feminino. Quatro das 7 crianças/adolescentes tinham CU associada (em 3 diagnosticada simultaneamente e numa diagnosticada 3 anos antes). Uma criança apresentava ainda fenómenos de vasculite. Em todos, detetou-se aumento da GGT e/ou FA, pelo menos 3 vezes superior ao limite superior do normal. A IgG estava aumentada em 3 doentes. No grupo de doentes com CEP detetaram-se os seguintes auto-Acs: ANA – 3 (43%), SMA – 5 (71%), ANCA – 2 (29%) e anti-proteinase 3 – 1 (14%). Os valores das titulações variaram entre 1/40 e 1/320. Também neste grupo, num doente os ANA foram negativos no primeiro estudo analítico e só posteriormente positivaram (caso 15). Em relação aos aspetos imagiológicos, observou-se ectasia da via biliar principal ou das vias biliares intra-hepáticas em 2 doentes.

, 1992 and Bader and Wrbitzky, 2006). Based on these extrapolated CEV concentrations, the proportions above the reference value were used. For the non-smokers, the reference value is clearly defined in the literature, i.e. 10 pmol/g globin (Kraus et al., 2009). In contrast,

for smokers, the reference value in the general population is less unequivocal (Kraus et al., 2009). For this study, an extrapolated CEV concentration of 200 pmol/g globin was used as cut-off for the smokers. CEV concentrations above the reference value of 10 pmol/g globin were observed in 37.3% of the non-smokers in the EZ as compared to 11.5% of the ‘Controls’ outside the EZ. The 95th percentiles were 635 and 22 pmol/g globin, respectively (Table 4). In contrast, in the smokers (Table 5), the proportion Adriamycin mouse exceeding www.selleckchem.com/products/LBH-589.html the reference value of 200 pmol/g globin was higher in the ‘Controls’ outside the EZ (68.4%) as compared to the EZ (40.0%). The 95th percentiles and the maxima, however, were higher in the EZ than in the ‘Controls’. To verify whether the CEV concentrations above the reference values in the group of ‘Controls’ outside the EZ could be explained by misclassification by residential address and/or by occupational exposure to ACN, an additional interview was done in all three

non-smokers and in 8 of the 13 smokers. Two of the non-smokers and 5 of the 8 smokers reported they had been in the EZ at the time of or in the days following the train accident.

None of the persons was working in the production of polymers, …. occupationally. Five smokers did not participate in the additional interview and thus kept Histamine H2 receptor the classification ‘outside the EZ’ as based on their residential address. After correction for localisation as obtained by the additional interview (Table 4), one (4.2%, CEV concentration of 16 pmol/g globin) of the remaining non-smokers outside the EZ had CEV concentrations above the reference value in contrast with 37.3% in the EZ (Chi-square test, P value = 0.003). In the remaining smokers outside the EZ ( Table 5), 57.1% kept CEV concentrations above the reference value, as compared to 40.0% in the smokers of the EZ (Chi-square test, P value = 0.394). In zone 1 (EZ1) and zone 2 (EZ2), 50.0% and 35.0% of the non-smokers (Table 4) had CEV values above the reference level of 10 pmol/g globin, respectively (Chi-square test, P value = 0.310). In zone 1 (EZ1), the concentrations did not exceed a remarkably low maximum of 65 pmol/g globin, the 95th percentile being 36 pmol/g globin. In contrast, in zone 2 (EZ2), the highest CEV concentrations of the whole local population were observed.

9A and B). Ebs (25 μM), (PhSe)2 (50 μM), and (PhTe)2 (50 μM) inhibited oxygen consumption in intact liver mitochondria supported either by pyruvate/glutamate (complex I substrates; Fig. 10A) or succinate (complex II substrate; Fig. 10B) as substrates. For mitochondrial oxygen consumption, the inhibitory potency order was Ebs ∼ (PhTe)2 > (PhSe)2, independent of the substrate used. In fact, Ebs and (PhTe)2 completely inhibits oxygen consumption, whereas (PhSe)2 was less active. Taking into account, the results obtained with intact mitochondria are in accordance with our findings using mitochondrial membranes (isolated complexes

assay). The results presented here indicate that the hepatic and renal toxicity of organochalcogens can be, at least in part, mediated Trichostatin A molecular weight by mitochondrial dysfunction via inhibition of different mithochondrial complexes, which can explain our previous results (Puntel et al., 2010). Here we

found that mitochondrial complex I was the key complex targeted by the organocompounds (almost 100% inhibited), followed by the complex II, whereas the inhibition of complex III and complex IV was negligible. Furthermore, both hepatic and renal mitochondrial preparations seem to be similarly inhibited by organochalcogens. Alectinib In fact, despite of different susceptibility of liver and kidney tissues after in vitro or in vivo exposure to organochalcogens ( Nogueira and Rocha, 2010 and Nogueira and Rocha, 2011), isolated hepatic Sitaxentan and renal mitochondria tended to respond similarly to the inhibitory properties of organochalcogens. Thus we suggest that the differences in the tissues susceptibility when exposed to organochalcogens ( Nogueira and Rocha, 2010 and Nogueira and Rocha, 2011) can be associated with other factors, such as differential

distribution and metabolism of organochalcogens in these tissues. Moreover, here we have used mitochondrial membranes in order to study the direct effect of organochalcogens on the complexes activity to avoid indirect effects of organochalcogen on complexes via modification of mitochondrial functionality (extent of polarization, presence of additional membrane barriers, etc., for details see (Puntel et al., 2010)). We know that the amounts or activities of specific complexes and enzymes can be useful to test specific hypotheses but should generally be held in reserve and not used as the primary assay for mitochondrial dysfunction (Brand and Nicholls, 2011). Hence, oxygen consumption data using intact mitochondria (Fig. 10) validated our findings with mitochondrial membranes and suggested that the inhibition of mitochondrial complexes is involved in the reduction of oxygen consumption by intact mitochondria.

Ich skuteczność została potwierdzona w kilkunastu badaniach przep

Ich skuteczność została potwierdzona w kilkunastu badaniach przeprowadzonych u dzieci. Najdłużej stosowanym lekiem biologicznym w terapii CD jest infliximab, chimeryczne mysio-ludzie przeciwciało monoklonalne klasy IgG1. Model podawania infliximabu w terapii indukującej remisję

(5 mg/kg dożylnie w tygodniu 0–2–6), a następnie w terapii podtrzymującej co 8 tygodni, jest powszechnie stosowany zarówno w populacji selleck chorych dorosłych, jak i dzieci. Skuteczność infliximabu u dzieci z CD została potwierdzona w wielu badaniach. Jednym z pierwszych badań wykazującym bardzo dobrą skuteczność podaży pojedynczej dawki infliximabu u dzieci było badanie przeprowadzone przez Baldassano i wsp. [29]. Podobny rezultat leczenia odnotowano w badaniu opublikowanym przez Cezarda i wsp. [30]. Kluczowym badaniem potwierdzającym Osimertinib mw skuteczność i bezpieczeństwo stosowania infliximabu nie tylko w indukcji remisji, ale również w jej podtrzymaniu, przeprowadzonym na dużej grupie pacjentów z średniociężką i ciężką postacią choroby Leśniowskiego i Crohna jest badanie REACH opublikowane w 2007 r. [31]. Wykazano, że schemat podaży infliximabu co 8 tygodni w podtrzymaniu remisji jest skuteczniejszy niż co 12 tygodni. Wyniki tego badania potwierdzają, że infliximab jest lekiem skutecznym w stosowaniu przy

terapii zarówno indukującej, jak i w podtrzymującej remisję w grupie dzieci z ciężką i średniociężką postacią choroby Leśniowskiego i Crohna, nieodpowiadającą na leczenie konwencjonalne. Podobne wyniki potwierdzające efekt stosowania infliximabu uzyskano w badaniu przeprowadzonym w populacji polskich dzieci [32] and [33]. Warto wspomnieć również o wynikach badań prospektywnych przeprowadzonych w małych grupach pacjentów [34] and [35]. W tych badaniach stwierdzono lepszą odpowiedź na pojedynczą dawkę infliximabu u pacjentów z krótkim czasem trwania choroby Leśniowskiego i Crohna. Związane jest to najprawdopodobniej z większą skutecznością preparatu anty-TNF-α u pacjentów

z aktywnym stanem zapalnym niż u osób z długotrwającą chorobą i większą komponentą zwłóknienia. Dodatkowo wykazano, że terapia infliximabem u dzieci umożliwia uzyskanie głębokiej remisji z całkowitym eltoprazine wygojeniem błony śluzowej [29], [32] and [36]. Podsumowując, obecnie infliximab jest stosowany w indukcji, jak i w podtrzymaniu remisji u pacjentów, również dzieci, z średniociężką i ciężką postacią choroby Leśniowskiego i Crohna przy nieskutecznym leczeniu konwencjonalnym. Jest również lekiem z wyboru w momencie wystąpienia przetok [37] and [38]. Jednak w blisko 50% przypadków u pacjentów leczonych infliximabem występuje konieczność zwiększenia dawki, a u około 30% pacjentów obserwuje się utratę odpowiedzi na stosowane leczenie w ciągu trzech lat stosowania [39]. Związane jest to najprawdopodobniej z chimeryczną strukturą preparatu oraz wytworzeniem przeciwciał przeciwko infliximabowi.

“Performing reaction sequences in one pot in a sequential or even simultaneous fashion avoids time-consuming or yield-reducing isolation and purification of the intermediates [1 and 2]; as a consequence the amount of chemicals/solvents required for extraction/purification of intermediates is minimised leading to an improved E factor [3]. Cascades involving reduction KPT 330 as well as oxidation steps are still a challenge due to the diverging reaction conditions. Since in living cells oxidation and reduction processes are performed simultaneously, enzymes are probably the perfect catalysts to be exploited for synthetic redox cascade applications [4]. In this review, artificial cascades involving an oxidation step followed by a reduction step, or vice versa, will be discussed, whereby at least one redox step is catalysed by an enzyme. The focus is on cascades published during the past 4 years. Cascades employing fermenting cells or involving in vivo metabolism will not be discussed as well as concepts for cofactor/cosubstrate recycling; furthermore, cascades involving the catalase-promoted disproportionation of hydrogen peroxide are out of scope. The easiest approach to performing such

redox cascades is to run the first redox reaction MycoClean Mycoplasma Removal Kit until completion and then start the second step by adding the required reagents; thus, the two steps are separated by Apoptosis inhibitor time but performed in the same pot. More challenging is to run the two redox reactions at the same time, thus simultaneously in one pot. Here two cases can be distinguished: The simpler case is that the oxidation and the reduction steps are working independently of each other; thus, reagents for the oxidation step as well as for the reduction step are required. The more demanding case is that the oxidation and reduction steps are interconnected: it would

be desirable that the formal electrons gained in the oxidation step are consumed in the reduction step. This represents a redox neutral cascade; thus, in an ideal case no additional reducing or oxidising agents are required. Consequently, the review was subdivided into the following subsections (Figure 1): (1a) simultaneous redox neutral oxidation–reduction cascades, (1b) simultaneous independent redox cascades in one pot and (2) subsequent oxidation–reduction cascades performed in one pot but separated by time. The (bio)catalysts working in concert in simultaneous oxidation–reduction cascades can be regarded as an interactive catalyst network. In the special case of redox neutral cascades, it represents an interconnected catalyst network.
