01 mol/L sulfuric

acid BMN 673 mw as eluent at 0.4 mL/min flowrate. The column was calibrated for at least 3 h before use, utilizing the same solution under the same conditions as the separation. Fig. 1 shows the acidification profiles of milk (A) and milk supplemented with 40 mg of inulin/g (B) by pure cultures of S. thermophilus (St) and L. rhamnosus (Lr) and a co-culture of S. thermophilus with L. rhamnosus (St–Lr) at 42 °C until reaching pH 4.5. It should be noted that the time to complete the fermentation depended not only on inulin addition but also on possible interactions between these two microorganisms. In the presence of inulin, the time to complete the fermentations by the St–Lr co-culture and the pure cultures of St and Lr was 48.1, 13.9 and 8.7% shorter than without inulin, respectively (panel A). Such a marked effect demonstrates that inulin stimulated the metabolism of both microorganisms, thus confirming its

prebiotic effect already reported for lactobacilli ( Donkor et al., 2007, Makras et al., 2005 and Oliveira et al., 2009a). The very long fermentation time of pure Lr culture (15.0 h) could have been due either to the need of this microorganism to co-metabolize KRX-0401 in vitro citrate or to the inducible feature of its citrate transport system ( Jyoti et al., 2004), while the quicker fermentation by the co-culture with respect to the single cultures could have been the result of synergistic effects between St and Lr. Fig. 2 and Fig. 3 show the fermentation behavior in skim milk of St, Lr, and St–Lr, without and with 40 mg of inulin/g, respectively. The most evident characteristics of these fermentations are: (1) the higher growth of S. thermophilus

with respect to L. rhamnosus, (2) the partial consumption of lactose, (3) the formation of lactic acid as the major metabolic product, and of acetic acid and ethanol as typical co-products of heterolactic fermentation, (4) the release of galactose, as the result of its slow metabolization, and (5) the accumulation of diacetyl and acetoin in the medium at very low levels. Fig. 2 clearly shows Niclosamide that both mono-cultures as well as the co-culture fermented mainly the glucose moiety of lactose, while a relevant portion of galactose was excreted in the medium. However, the pure culture of Lr was shown to metabolize 6 g/100 g more galactose than that of St and the St–Lr co-culture. This behavior may be explained by the weak transcription from gal promoters or mutations in the Leloir genes by many strains of S. thermophilus ( de Vin et al., 2005). Moreover, according to Tsai and Lin (2006), in L. rhamnosus, the galactose moiety of lactose could be metabolized also by two alternative pathways, specifically the Leloir and the tagatose 6-phosphate pathways. As a result, the final production of lactic acid by the Lr pure culture was little higher (9.8 g/L) than by both the St pure culture (9.2 g/L) and the St–Lr co-culture (9.2 g/L).

These nutrients, especially the omega-3 fatty acids, are vital to human fetal development with eicosapentaenoic acid (EPA) and docosapentaenoic acid (DPA) contributing to development of the central nervous system (Alessandri et al., 2004 and Myers et al., 2007). Women consuming more fish during pregnancy have babies with higher IQs and fewer behavioral problems than mothers that ate little

or no fish high in omega-3 fatty acids (Hibbeln et al., 2007). Additionally, fish consumption during pregnancy has been linked to a decrease in preterm delivery (Olsen and Secher, 2002), increased likelihood of foveal steroactuity in the child (Williams et al., 2001), and to development of the child’s immune system (Denberg et al., 2005 and Dunstan et al., 2004). Consumption of fish that accumulate C59 research buy monomethyl mercury (MeHg+) in their muscle is the primary pathway of exposure to mercury (Hg) in humans (Wagemann et al., 1997). Inorganic Docetaxel nmr forms of Hg enter ecosystems through natural sources such as volcanism,

and anthropogenic sources such as mining, coal combustion, and cement production (AMAP, 2011). Hg is converted to the more toxic MeHg+ by bacteria (AMAP, 2011) and in most systems biomagnifies with each trophic transfer. MeHg+ is highly bioavailable in humans [>95% of ingested dose absorbed; Aberg et al. (1969)], easily passes the placenta to the fetus, and crosses the blood brain barrier (BBB), potentially adversely affecting the developing nervous system (Kjellström, 1991, McKeown-Eyssen et al., 1983 and Stewart et al., 2003). Nearly 100% of the Hg that bioaccumulates in upper-trophic level fish skeletal muscle is MeHg+ (Borum et al., 2001). Effects on brain function associated with prenatal MeHg+ exposure were found to be multi-focal and permanent (Debes et al., 2006) although these results may have been confounded by Staurosporine mw prenatal exposure to polychlorinated biphenyls (Dietz et al., 2011). The amount of

Hg exposure to humans from fish consumption varies significantly by the age and trophic level of the fish consumed (Airey, 1983 and State of Alaska Epidemiology Bulletin, 2007) and the frequency (Gaxiola-Robles et al. companion paper) and amount (mass) of the fish meals. Pouzaud et al. (2010) found that a global increase in seafood consumption could lead to Hg exposure above some conservative consumption advisory limits for pregnant women, and examined the balance between Hg exposure risk and the beneficial effects of omega-3 long-chain polyunsaturated fatty acid intake. Pouzaud et al. (2010) concluded pregnant women consuming a high proportion of some fatty fish, such as sardines and salmon, meet the omega-3 long-chain polyunsaturated fatty acid intake requirements without exceeding the advisory limits for Hg. In addition, Myers et al.

“Treatment of patients with type 2 diabetes (T2D) aims to reduce insulin MRIP resistance and enhance beta-cell secretion through lifestyle modification and use of metformin, followed by the combination of other oral antidiabetic drugs (OADs). Nevertheless, due to the progressive deterioration in glycaemic control, insulin therapy is often required to achieve glycaemic goals [1]. Lowering glucose levels to the recommended HbA1c level <7.0% is associated with reduction in microvascular complications and, if achieved in a timely manner after diagnosis, may also improve macrovascular outcomes [1]. Sitagliptin, a widely used, highly selective oral dipeptidyl peptidase-4 (DPP-4) inhibitor, can be used in dual or triple therapy when glycaemic control is not attained with metformin [1] and [2]. Although DPP-4 inhibitors are weight-neutral and have a low hypoglycaemia risk, they are associated with modest glucose-lowering activity (HbA1c reduction 0.5–0.9%) [3] and [4]. In a head-to-head comparison, significantly better glycaemic control was achieved with insulin glargine versus sitagliptin, both with metformin, in insulin-naïve patients with T2D, although symptomatic hypoglycaemia was also significantly greater with this insulin-based regimen [5].

2. Family controls comprised unaffected relatives as defined in this manner, and spouses. Spouses were recruited to increase sample size, reduce residual confounding from unmeasured environmental factors shared with HBM cases and who, as a function of their genetic independence, would be unlikely to share common polygenic influences over BMD. Recruitment ran from September 2008 until April 2010. All participants were clinically assessed by one doctor

using a standardised structured history and examination questionnaire, after which DXA scans were performed for relatives and spouses, using local GE Lunar Inc. Madison, WI, USA) DXA systems applying manufacturer’s standard scan and positioning protocols, and weight and routine height measurements were recorded. Body mass index (BMI) was calculated as weight (kilograms)/height (metres)2. Current and historical physical activity data were collected from HBM cases and family Alectinib in vivo controls

by questionnaire (including the validated international physical activity questionnaire [IPAQ] [6], [7], [8] and [9]). Participants were excluded if under 18 years of age, pregnant or unable to provide written informed consent for any reason. The Hertfordshire Cohort Study is a population based cohort study tracing 42,974 men and women born in Hertfordshire during 1931–1939 and still living there during the period 1998–2003. Individuals were traced using the NHS BMS754807 central registry at Southport and the Hertfordshire Family Health Service Association. Full details of the study design have previously been reported [10]. A planned subsample of 6099 individuals were invited to participate in a clinical study and 3225 (53%) men and women aged 60–75 years were recruited and completed home interviews [10]. In 2004 and 2005 a subgroup (from East Hertfordshire)

were followed up and 322 men (65%) and 321 women (69%) re-attended, completed lifestyle questionnaires which included questions concerning medical history including fractures, smoking and alcohol consumption. Height was measured to the nearest 0.1 cm using a Harpenden pocket stadiometer and weight to the nearest 0.1 kg using floor scales, at the time of pQCT assessment [11]. pQCT scans were performed at the distal and mid-shaft of the Adenosine tibia (4 and 66% from the distal endplate) in the non-dominant lower limb using a Stratec XCT2000L (Stratec Medizintechnik, Pforzheim, Germany); voxel size 0.5 mm, CT speed 30 mm/s, XCT software version 5.50d. A reference line at the distal endplate was determined from initial frontal scout view. Cortical bone was defined using a threshold above 650 mg/cm3 (optimal for bone geometry [12]). Trabecular bone was identified by elimination of cortical bone and therefore trabecular bone mineral density (tBMD) was defined as a density < 650 mg/cm3.

28d, the equivalent of 4.2 IQ points, and a significantly higher Verbal IQ than girls by 0.16d, the equivalent of 2.40 IQ points. These results provide additional evidence that modest but significant sex differences exist in intelligence, thus refuting continued assertions that no differences exist (e.g., Halpern, 2012 and Sternberg, 2014)

Second, there are six statistically significant sex differences on the subtests of the WISC-R in the present Chinese sample shown in Table 1. Boys obtained AZD5363 purchase significantly higher means than girls on Information, Picture Arrangement, Picture Completion, Block Design and Object Assembly, and girls obtained a significantly higher mean than boys on Coding. Third, on several of the subtests, the sex differences in the present Chinese Gefitinib research buy sample were consistent with those in the American standardization sample shown in Table 2. The advantage of boys in the present Chinese sample on Information is virtually identical to that in the United States with statistically significant

ds of .44 and .37, respectively. These results confirm those of several studies of the Wechsler information tests among adults and of other studies finding that among adults men have significantly higher means than women on information and general knowledge ( Lynn and Irwing, 2002 and Lynn et al., 2002). The advantage of boys in the present Chinese sample on Picture Arrangement is consistent with that in the American standardization sample with statistically significant ds of .19 and .11, respectively. The advantage of boys on Object Assembly in the present Chinese sample is also consistent with that in the United States with statistically significant ds of .38 and .18, respectively. Boys obtained higher scores on Picture Completion in the present Chinese sample (.19) and in the U.S. (.15) and on Block Design with ds of .19 and .15, respectively. The higher means obtained by boys in both China and the United States on Picture Arrangement, Object Assembly, Picture

Completion and Block Design are explicable because these are all measures of visual–spatial abilities on which males typically obtain higher means than females ( Linn 3-mercaptopyruvate sulfurtransferase and Peterson, 1985 and Voyer et al., 1995). The statistically significant advantage of girls on Coding in the present Chinese sample is consistent with the higher mean obtained by girls in the United States with ds of .41 and .53, respectively. Fourth, on Comprehension and Similarities the sex differences in the present Chinese sample, where both boys and girls score similarly at .00 and −.01, is consistent with those in the American standardization sample with ds of .01 and .07. Fifth, there is some inconsistency in the sex difference in Vocabulary, where there was no significant difference between boys and girls in the Chinese sample (d = −.03) but boys obtained a significantly mean in the American sample (d = .14).

Aż 50–80% wszystkich aktywnych seksualnie kobiet ulega zakażeniu HPV przynajmniej raz w życiu [11, 12, 13]. Z uwagi na wewnątrzkomórkowy cykl replikacji HPV, głównie w powierzchniowych warstwach nabłonka, AT13387 cost oraz brak wiremii, immunogenność wirusa podczas naturalnego zakażenia jest mała, a przebycie zakażenia nie zapewnia długotrwałej odporności i nie chroni przed kolejnym zakażeniem HPV należącym do tego samego lub innego typu [14]. Zdecydowana większość zakażeń HPV (70–80%) ustępuje jednak samoistnie w wyniku prawidłowej odpowiedzi immunologicznej w okresie od kilku

miesięcy do dwóch lat, nie wywołując zauważalnych objawów lub trwałych następstw [3, 15]. Utrzymywanie się zakażenia HPV dłużej niż 24 miesiące jest związane z wirusem o wysokim potencjale onkogennym. Według wytycznych WHO oraz wielu międzynarodowych i krajowych

towarzystw naukowych (ginekologicznych, onkologicznych), optymalna profilaktyka raka szyjki macicy obejmuje zarówno profilaktykę pierwotną (doradztwo oraz szczepienia), w celu zapobiegania zakażeniom HPV, należącym do wysoce onkogennych typów, oraz profilaktykę wtórną (wczesne wykrywanie dysplazji i raka – przesiewowe badania cytologiczne) i leczenie nieprawidłowości w obrębie błony śluzowej szyjki macicy [16, 17, 18, 19]. Warunkiem powodzenia realizacji programów profilaktycznych jest budowanie świadomości społeczeństwa w zakresie możliwości zapobiegania i wczesnego wykrywania oraz leczenia choroby. W realizacji tego zadania ważną rolę spełniają Enzalutamide także pediatrzy i lekarze rodzinni. W 2006 i 2007 roku European Medicines Evaluation Agency (EMEA) zarejestrowała i dopuściła do stosowania w Europie (w tym w Polsce) dwie szczepionki przeznaczone do profilaktyki Loperamide zmian przednowotworowych szyjki macicy oraz raka szyjki macicy, związanych przyczynowo z zakażeniem HPV. Były to odpowiednio Silgard [20] (firmy MSD) oraz Cervarix [21] (firmy GSK). Charakterystykę obu szczepionek przedstawiono w tabeli

2. Kilkuletnie (od 3 do 6 lat) obserwacje w ramach badań klinicznych wskazują, że szczepienie pierwotne (3 dawki) zmniejsza ryzyko rozwoju stanu przedrakowego szyjki macicy, a szczepienie kobiet niezakażonych HPV jest 2–3-krotnie skuteczniejsze niż szczepienie przeciętnej populacji kobiet aktywnych seksualnie, w której znaczący odsetek już jest zakażony (tab. 2). U kobiet zakażonych HPV określonego typu szczepienie jest bowiem nieskuteczne w profilaktyce zmian przedrakowych i raka wywołanego tym typem HPV [2]. Długotrwała ochrona po szczepieniu ma istotne znaczenie ze względu na ryzyko zakażenia HPV utrzymujące się przez cały okres aktywności seksualnej. Aktualnie nie zaleca się podawania dawek przypominających ani szczepionki Cervarix, ani Silgard [29, 30, 43], jednak obserwacje kliniczne nadal trwają. Nie wykryto do tej pory markera immunologicznego korelującego z kliniczną ochroną przed przetrwałym zakażeniem HPV oraz CIN2+ i rakiem.

Fluvial process dynamics in stable alluvial channels includes a broad range of interacting processes that mobilize, transport, erode, and deposit sediment—and create, maintain, and degrade

riparian habitat. One significant aspect of this range of fluvial processes that is altered by incision affects the way channels interact with their floodplains, or lateral connectivity (Brierly et al., 2006) that includes Nutlin-3 datasheet transfer of water, sediment, nutrients, organic matter, and biota between the channel and adjacent floodplain (Pringle, 2001, Pringle, 2003 and Brookes, 2003). Heterogeneous channel-floodplain dynamics related to connectivity result in biocomplexity that is lost as incision disconnects floodplains (Amoros and Bornette, 2002), leaving the former floodplain abandoned as a terrace alongside the channel. Dynamics in incised alluvial channels include processes such as bank erosion, selleck screening library which is part of a sequence of events that follows channel incision and increases in bank height or bank angle. In incised channels, banks may reach a critical threshold height where any increase in channel bed lowering that increases bank height may in turn cause bank erosion (Carson and Kirkby, 1972 and Thorne, 1982). Both widening and channel

narrowing have been reported following incision in alluvial channels. In the case of widening following incision, as bank angles lessen during mass wasting and bank retreat, another threshold may eventually be reached where at a given bank height the low angle surface is stable enough to support pioneer woody plants (Simon, 1989). Conceptual models describe the relation between incision

and bank erosion as following a series of steps in a sequence of adjustment (Schumm et al., 1984, Simon and Hupp, 1986, Simon, 1989 and Doyle et al., 2003). Steps after initial incision may Acyl CoA dehydrogenase include: increased bank height and isolation of the former floodplain as a terrace, bank erosion, channel aggradation and creation of a new lower bank angle and height, and eventual formation of a new stable channel with a correspondingly lower inset floodplain that can support riparian vegetation establishment (Simon, 1989); a sequence of adjustments estimated to take hundreds to thousands of years (Simon and Castro, 2003). However, one conceptual model does not explain the variation in evolutionary pathways or rates in various environments (Doyle et al., 2003 and Beechie et al., 2008). In fact, numerous recent studies suggest that narrowing follows incision, often in association with embankments and erosion control structures (Surian, 1999, Łajczak, 1995, Winterbottom, 2000, Rinaldi, 2003 and Rădoane et al., 2013). Moreover, some rivers progress through a sequence of changes that includes spatial differences with respect to narrowing and incision followed by widening and aggradation (Surian and Cisotto, 2007). Steiger et al.

Our results confirm that, by

exporting contaminated particles originating from the main inland radioactive plume, coastal rivers are likely to have become a significant Cobimetinib and perennial source of radionuclide contaminants to the Pacific Ocean off Fukushima Prefecture. This could at least partly explain the still elevated radionuclide levels measured in fish off Fukushima Prefecture (Buesseler, 2012). Quantification of the hydro-sedimentary connectivity between hillslopes and the identified sinks in the three coastal catchments provided additional information on the timing of sediment transfer processes and their preferential pathways observed along the investigated rivers (Fig. 6). Paddy fields located in the upstream part of both Nitta

and Mano River catchments were well connected to the thalweg and they constituted therefore an important supply of contaminated material to the rivers or to small depressions located in the floodplain. In contrast, in the flat coastal plains of those catchments, large cultivated surfaces were poorly connected to the rivers. A distinct situation was observed in the Ota River catchment. In the upper part of this catchment, land use is dominated by forests that are much less erodible than cropland, but that could deliver contaminated material to the river during heavy rainfall (Fukuyama et al., 2010). Furthermore, the high slope gradients observed in this area may have led to the more frequent occurrence of mass movements in this area. This contaminated material was then stored in the large Yokokawa reservoir (Fig. 6a). In the downstream part of the Ota River catchment, paddy Sorafenib mw fields located in the vicinity of rivers were well Pyruvate dehydrogenase lipoamide kinase isozyme 1 connected to the watercourses which contrasts with the situation outlined in the coastal

plains of the Mano and Nitta River catchments (Fig. 6b). This transfer timing and preferential pathways are confirmed when we plot the contamination in total 134+137Cs measured in sediment collected during the three fieldwork campaigns along the longitudinal profiles of the investigated rivers (Fig. 7). Overall, we observed a general decrease in the contamination levels measured between the first and the last campaign, especially in the Nitta River catchment (Fig. 7, left panels) where the difference is particularly spectacular along the upstream sections of the Nitta (Fig. 7; profile c–d) and Iitoi Rivers (Fig. 7; profile g–e). Our successive measurements suggest that there has been a progressive flush of contaminated sediment towards the Pacific Ocean. However, the mountain range piedmont and the coastal plains that have remained continuously inhabited constitute a potentially large buffer area that may store temporarily large quantities of radioactive contaminants from upstream areas. However, our data and the drawing of the longitudinal profiles suggest that this storage was of short duration in the river channels.

p. injections of saline. During the withdrawal period, the rats were orally administered KRGE (20 mg/kg/d or 60 mg/kg/d) dissolved in distilled water (DW) or only DW once/d for 3 d (Fig. 1B). Thirty min after the third dose of KRGE, the rats were tested for anxiety-like behavior in an elevated plus maze (EPM) to evaluate the possible

anxiolytic effects of KRGE during EW. Immediately after the EPM test, each rat was decapitated and the entire brain was removed and stored at −80°C. Tissue samples from the CeA and VTA were punched out for neurochemical analyses; coordinates for the CeA [anterior-posterior (AP) = −2.0 mm, medial-lateral (ML) = −4.2 mm, dorsal-ventral (DV) = −7.8 mm) and VTA (AP = −6.0 mm, ML = −0.7 mm, DV = −7.8 mm) were based on the Paxinos and Watson rat brain atlas [7] and [15]. At the same time, blood samples were collected for a radioimmunoassay JAK inhibitor (RIA) of corticosterone (CORT) levels. The EPM (Shanghai Yishu Co., Shanghai, China) consisted of a plus-shaped maze that was elevated 50 cm above the ground and equipped with a video tracking system. Each of the four arms was 40 cm long × 10 cm wide; two of the opposing arms were enclosed by 30 cm high black wooden walls (closed arms) whereas the

other two opposing arms were devoid of walls (open arms). The EPM test is thought to induce anxiety due to the natural fear of open and elevated spaces that exists in rodents. The number of entries

into open arms and the time spent in open arms are negatively correlated with the www.selleckchem.com/products/ch5424802.html anxiety level of the rat. Thirty min after the third dose of KRGE, all rats were individually subjected to the EPM test as described previously 4-Aminobutyrate aminotransferase [7]. Briefly, without any pretest handling, each rat was placed in the center of the maze, after which the cumulative time spent in each arm and the numbers of entries into the open or closed arms were recorded during a 5 min test session. The percentage of time (T) spent in open arms was calculated as follows: PercentageofTspentinopenarms=Tspentinopenarms(Tspentinclosedarms+Tspentinopenarms). Approximately 1.5 mL of blood collected from each rat was mixed with EDTA (20 mg/mL, 20 μL) and centrifuged (1,000 × g) at 4°C for 10 min. The plasma was separated out and CORT was measured using an ImmuChem double antibody 125I RIA kit (MP Biomedicals, Orangeburg, NY, USA) with the values expressed as ng/mL [7]. To determine the involvement of amygdaloid DA receptors in the expected anxiolytic effects of KRGE during EW, another set of experiments was conducted using the same EW schedule described above, in which the rats were given an intra-CeA infusion of either a D1R antagonist (SCH23390) or a D2R antagonist (eticlopride) 5 min prior to the third dose of KRGE (60 mg/kg). These rats were also tested in the EPM. All rats were placed under anesthesia (sodium pentobarbital, 50 mg/kg, i.p.

4). DEXA, but not OA, reduced IL-6 and KC levels as compared with CLP–SAL (Fig. 4). No significant changes in the level of IL-10 Dolutegravir in BALF were observed among the groups (Fig. 4). In the present experimental model of sepsis induced by CLP in mice: (1) a single dose of OA (10 mg/kg) or DEXA (1 mg/kg) prevented impairment in lung mechanics, reduced alveolar collapse and neutrophil infiltration, and attenuated

cell apoptosis in the lung, kidney, and liver; (2) DEXA, but not OA, significantly decreased IL-6 and KC protein levels in BALF; and (3) OA, but not DEXA, increased SOD and prevented the increase in iNOS mRNA expression in lung tissue. The CLP model is considered to be the crucial preclinical test for any new treatment of human sepsis (Matute-Bello et al., 2001 and Lang and Matute-Bello, 2009), since it involves similar inflammatory and oxidative pathways (Orfanos et al.,

2004). The doses of OA and DEXA used in the current investigation were based on pilot studies considering improvement in lung function (data not shown). Dexamethasone was chosen rather than other corticosteroids that could reach superior pulmonary concentration, such as methylprednisolone GDC-0973 concentration (Greos et al., 1991), owing to its intraperitoneal absorption characteristics, which are comparable to those of OA (Engelhardt, 1987). The dose of dexamethasone used herein was 1 mg/kg, which also improved lung morphofunctional variables in paraquat-induced lung injury (Santos et al., 2011). Two inflammatory pathways (Lang et al., 2002, Thimmulappa et al., 2006a, Thimmulappa

et al., 2006b and Guo and Ward, 2007) were analyzed to evaluate the mechanisms of action of OA and dexamethasone in sepsis. The first pathway is associated with the inhibition of signaling by NF-κB, modulating pro-inflammatory and anti-inflammatory MG-132 mediators. The pro-inflammatory cytokines KC and IL-6 play important roles in the immune response in sepsis (Andaluz-Ojeda et al., 2012 and Reinhart et al., 2012). KC possesses potent chemotactic activity for neutrophils (Watanabe et al., 1991) and has been suggested as an important mediator of tissue damage. IL-6 is elevated in septic patients and correlates with severity and outcome (Kantar et al., 2000). IL-10 is expressed in high concentrations during sepsis and can downregulate expression of TNF-α as well as other inflammatory cytokines (Marchant et al., 1994). The second pathway is associated with mechanisms related to oxidative stress. In this line, transcription factor Nrf2, the antioxidant enzymes GPx, CAT, and SOD, and iNOS were measured. Nrf2 regulates antioxidant defenses that protect against inflammation by inhibiting oxidative tissue injury (Kong et al., 2011). GPx acts as a reducing system for H2O2, and eliminates several toxic peroxides, preventing lipid peroxidation (Comhair and Erzurum, 2002). CAT catalyzes H2O2 dismutation and is more effective in the presence of high H2O2 concentrations.
