no other compound is known to be provided. However, the obtained protein find more profile suggested that FPP might be provided from rhizobia this website to plant root cells. In the quinone biosynthetic pathway, the enzymes necessary to FPP biosynthesis, such as isopentenyl pyrophosphate isomerase (mlr6371) and geranyltransferase (mlr6368), which are located in the rhizobia symbiosis island, were uniquely detected under the symbiotic condition (Figure 4b). These enzymes produce FPP from isopentenyl diphosphate and dimethyl allyl diphosphate. FPP is an intermediate in the mevalonate pathway, which is present in all higher eukaryotes and many bacteria. FPP is used for the biosynthesis of ubiquinone in CDK inhibitor M. loti. However, the enzymes which catalyze the ubiquinone biosynthesis reactions from FPP (shown in asterisks in Figure 4b) were not detected at the protein level. Additionally, the symbiosis island does not include genes encoding octaprenyl-diphosphate synthase (mlr7426) and 4-hydroxybenzoate polyprenyltransferase (mll7442), which are involved in the pathway of ubiquinone biosynthesis. On the other hand, higher plants utilize FPP as the

Thymidylate synthase intermediate precursor of many secondary metabolites, such as sesquiterpenes, triterpenes, and sterols [30]. It is reasonable to suppose that FPP is provided to the host legume from rhizobia as a source of secondary metabolites because FPP was synthesized only under the symbiotic condition, as the enzymes that metabolize FPP after its production were not detected in M. loti at the protein level. However, the estimation is just based on the obtained protein profile, and further investigation of the migration of FPP will be carried out by using deletion mutants, and by analysis at mRNA and

metabolite levels. Nucleotide sugar metabolism and peptidoglycan biosynthesis On the other hand, the enzymes involved in uridine diphosphate (UDP) sugar metabolism were not produced under the symbiotic condition (Figure 4c), and LPS transporters (mll3197, mll7564, mll7866) were not produced under the symbiotic condition. UDP-N-acetylglucosamine (UDP-MurNAc) is the starting material for LPS biosynthesis. LPS is known as one of the “nod factors,” which is secreted by the rhizobial body when it perceives the root through the flavonoid groups secreted from host legume [2]. The secretion of LPS is likely unnecessary under the symbiotic condition (after infection). In addition, UDP-N-acetylmuramic acid, the end product of this pathway, is the starting material of peptidoglycan biosynthesis. The enzymes of peptidoglycan biosynthesis were uniquely detected under the free-living condition (Figure 4d).

To further substantiate the importance of high NQO1 expression in breast cancer progression, we analyzed DFS and 10-year OS of 176 breast cancer cases using the Kaplan–Meier method and found that patients with high NQO1 expression had lower DFS and 10-year OS than those with low NQO1 expression (both P < 0.0001) (Figure  4). In addition, the expression of NQO1 was strongly associated with DFS and 10-year OS rates of patients with both early-stage tumors (P = 0.024) and late-stage tumors (P = 0.015) (Figure  5). Similarly, for patients with either Her2 low or high expression, high NQO1 expression showed significantly worse DFS and Olopatadine 10-year OS than those with low NQO1 expression (P = 0.010 and P = 0.023, respectively)

(Figure  6). Figure 4 Kaplan–Meier survival curves in patients with high and low NQO1 expression. (A) and (B) show comparison of DFS and 10-year OS, respectively, in NQO1 low-expression (L) and high-expression (H) patients. Figure 5 Kaplan–Meier survival curves of in early and late stage patients. (A) and (B) show comparison of DFS and 10-year OS, respectively, in NQO1 (L) and (H) patients of early stage. (C) and (D) show comparison of DFS and 10-year OS, respectively in NQO1 (L) and (H) patients of late stage. Figure 6 Kaplan–Meier survival curves in patients with Her2 positive and negative expression. (A) and (B) show comparison of DFS and 10-year OS, respectively, in NQO1 (L) and (H) patients with Her2 negative expression. (C) and (D) show comparison of DFS and 10-year OS, respectively, in NQO1 (L) and (H) patients with Her2 positive expression. Discussion NQO1 was first identified by Ernster and Navazio in the late 1950s [21]. After decades of research, considerable data has demonstrated that NQO1 can protect against natural and exogenous quinones. NQO1 expression in most human tissue types also suggests that it may function primarily in an antioxidant capacity in these cells.

More recently, RepSox cell line Thomas et al. [23] conducted a similar study, comparing isocaloric CM and CHO+Pro beverages and a CHO beverage comparable to that used by Karp et al. [22]. Time to exhaustion in the subsequent exercise bout was significantly longer with CM than either comparison beverage. Although the potential mechanisms for these findings are not clear, these studies support the potential efficacy of CM as a post-exercise recovery beverage following heavy endurance exercise. The present study was designed to compare recovery beverages in free-living

athletes within a collegiate team setting. Although this maximizes the generalizability of our findings for athletes, there were some relevant limitations to this design. Firstly, the free-living buy Alpelisib environment may have increased measurement error over the course of the study. Great 4EGI-1 mouse care was taken throughout the study to insure that training/nutritional conditions were virtually identical between the

two treatment periods. However, it is possible that activities outside the experimental protocols may have influenced the outcomes of the study. For example, four of the seventeen participants who completed the study were removed from statistical analyses (as described in Methods) due to large variations in baseline measurements (i.e. prior to ITD and beverage treatments), possibly due to activities outside of the study parameters. Six subjects failed to return completed dietary recall questionnaires, and thus we cannot be certain that nutrient intake did not vary between treatment periods for the entire sample. In addition, subjects were instructed to replicate the same dietary habits between treatment

periods, but were not required to arrive at the laboratory in a fasted state. Thus, differences in nutrient timing between treatment periods could also have influenced some of the study outcomes. Another acetylcholine limitation was the NCAA regulation limiting out-of-season practice time to a maximum of 8 hrs per week of ‘athletically related activities’ (NCAA Playing and Practice Limitations, Bylaw 17.1.5.2). As a result, it was not possible to implement an ITD period greater than 4 days in the present study. The prescribed training program was designed to increase daily training time by >25% per day between baseline and ITD periods (Table 1). However, due to adjustments in training plans to accommodate for inclement weather on two days (and maintain consistency between treatment periods), the ITD period increased daily training times by only 12% (Table 3). This training stimulus produced significant increases in muscle soreness ratings, and serum CK levels over the four-day period. However, MPSTEFS ratings and serum Mb were not significantly altered over time, and MVC actually improved over the four days of ITD.

PinX1 siRNA PinX1 siRNAs were designed using online software from Invitrogen company (http://​maidesigner.​Invitrogen.​com/​maiexpress/​). After blast and analysis for homology in human genome, three siRNAs PinX1-963,

PinX1-695 and PinX1-242 were selected and used to silence PinX1. Preliminary experiments indicated that PinX1-695 with sense sequence of 5′-GUAAAGAUGUGGAAAGUUATT-3′ and anti-sense sequence of 5′-TTCAUUUCUACACCUUUCAAU-3′ could effectively downregulate PinX1. Threrefore, it was synthesized as FAM-labeled siRNA and used in all experiments. Experimental design and cell transfection Cells at logarithmic phase were innoculated into 6-well plated cultured selleck in media without antibiotics for 24 h to reach 80-90% confluency. Cells were then transfected with pEGFP-C3-PinX1, and PinX1-FAM-siRNA using lipofectimaine 2000™ according to the protocol provided by the manufacturer. Untransfected cells and cells treated with lipofectimine 2000™ alone and cells transfected with pEGFP-C3 were used as controls. Cells were Selleckchem Birinapant observed 24-48 h after transfection under fluorescence microscope to examine transfection efficiency. RNA isolation and measurement of PinX1 and hTERT mRNA levels by RT-PCR Total RNA was extracted with Trizol 48 h after transfection following the manufacturer’s instruction.

Four μL mRNA of each sample was reverse transcribed into cDNA by AMV reverse transcriptase and used as template TPX-0005 in RT-PCR. PCR condition used for PinX1 and internal reference GAPDH was

94°C for 2 min followed by 25 cycles of 94°C for 1 min, 55°C for 1 min and 72°C for 2 min, and 72°C for 5 min. PCR condition used for hTERT and its internal reference GAPDH was 94°C for 4 min followed by 2-hydroxyphytanoyl-CoA lyase 30 cycles of 94°C for 30 s, 49°C for 30 s and 72°C for 45 s and 72°C for 5 min. The specific primers used in these reactions were followings: PinX1 forward 5′ TTTTCTCGAGATGTCTATGCTGGCTGAACG 3′ and reverse 5′ TTTTGAATTCTCATTTGGAATCTTTCTTC 3′; hTERT forward 5′ CCGAGTGACCGTGGTTTCTGTG 3′ and reverse 5′GGAAGCGGCGTTCGTTGTG 3′ and GAPDH forward 5′ GGAAGATGGTGATGGGATT 3′ and reverse 5′ GGATTTGGTCGTATTGGG 3′. The expected PCR products were 987 bp, 670 bp and 205 bp for PinX1, hTERT and GAPDH, respectively. The amplicons were analyzed by electrophoresis, imaged using UVI gel imaging system and quantified using Quantity one software. Expression levels of PinX1 and hTERT were normalized to internal reference GAPDH. Measurement of cell proliferation by MTT NPC 5-8 F cells at logarithmic phase were inoculated into 96-well plate with 1 × 105 cells in each well. Cell viability at 0 h, 24 h, 48 h and 72 h was examined using MTT method.

Detection of human MDR1 gene biodistribution Mice were necropsied on Day 3, 7, 14, 21 and 30, with three samples necropsied at one time. And the following tissues were collected: bone marrow, brain, heart, liver, kidneys, spleen, lungs and intestine. Tumors were also collected from the group A and B. Tissues were taken macroscopic examination and preserved in neutral-buffered 10% formalin. After 48 hours, the tissues were embedded in paraffin, stained with hematoxylin and eosin, and microscopically examined. A tissue microarray (TMA) was constructed (6 mm ×4 μm). Two duplicate specimens from each sample

were placed on the array. Paraffin-embedded sections were stained with standard immunohistochemical techniques as introduced in [10]. In situ hybridization experiments were carried out with a mixture of specific Nirogacestat mw digoxin-labeled

oligonucleotide anti-sense probe for check details the human MDR1 (TBD, China). The MDR1 DNA probe consisted of the fragment corresponding to nucleotides 514-482 of the human MDR1 mRNA (genebank accession number AF016535). ISH signals were scored with a fluorescence microscope (Olympus BX51, Tokyo, Japan). In situ hybridization was performed on paraffin-embeds tissue sections Oligomycin A according to the manufacturer’s protocol. The positive signal for human MDR1 was detected with fluorescein isothiocyanate. Consecutive tissue sections were also hybridized with sense probe under the same conditions. Detection of Adenovirus-specific antibody and Serum neutralizing factors (SNF) Adenovirus-specific antibody levels were evaluated by ELISA on Day 3, 7, 14 days after transplantation. Diluted serum samples were added to 96-well microtitier plates coated with the protein of adenovirus. Each sample had duplicate determination, tetramethylbenzidin were added to produce a colored reaction. The absorbance was read at 450 nm with a reference

filter of 650 nm with the microplate reader. To detect SNF against Ad-EGFP-MDR1, serum was incubated at 55°C Y-27632 in vitro for 30 min to inactivate complement. 2 × 105/well HEK 293 cells were plated into 24-well plates (BD, America) and incubated for four hours before sample dilution. Serum was incubated with equal volume of Ad-EGFP-MDR1 (MOI 10) for 1 hour at 37°C. The serum/Ad-EGFP-MDR1 mixtures were transferred onto the HEK293 cell and incubated 4 hours, supernatant was removed and fresh medium was added. The green fluorescence of cells was measured with flow cytometry at 24 hours after incubation. [11] Statistical analysis Hematology and ELISA results were expressed as mean ± standard error (S.E). Data were analyzed using unpaired student’s t-test, or one-way analysis of variance ANOVA with SAS (Biostatistics department, Chongqing Medical University). Significance was set at P < 0.05.

Statistical analysis All experiments were performed in duplicate and repeated at least three times on different days. The bacterial count was log10 transformed as described by Anderl et al. [21]. On different days of biofilm formation, all the data from a particular treatment and from particular time

points were grouped separately and the log reductions selleck chemicals in comparison to untreated biofilm at the respective time points were calculated. The effect of different treatments on biofilm eradication was evaluated by the Student’s t-test and P < 0.05 was considered significant. Data were analyzed using Excel software. Results Establishment of biofilms on microtiter plates in iron supplemented media K. pneumoniae biofilms was established in minimal (M9) media and bacterial count was enumerated on various days. Initially, bacterial count for the young immature 2nd day biofilms was 6.7 ± 0.08 Log10 CFU/ml followed by a peak on day 4 (7.12 ± 0.04 Log10 CFU/ml) and a further decline resulting in a bacterial count of 6.6 ± 0.10 Log10 find more CFU/ml on 7th day for the older mature biofilm. The effect of supplementation with different concentrations of FeCl3 in minimal media was buy Quisinostat studied on the biofilm growth. Addition of 10 μM FeCl3 enhanced the growth as a significant increase (p < 0.05) in the bacterial count was observed 2nd day onwards (Figure 1) in comparison with non-iron supplemented control wells.

This increase was consistent throughout the incubation period. On the contrary, wells supplemented with 100 and 1000 μM of FeCl3 showed reduction 4th day onwards with respect to control and 10 μM FeCl3 containing wells.

Antimicrobial treatment of biofilms grown on microtiter plates The effect of addition of iron antagonizing molecule i.e. CoSO4 on K. pneumoniae B5055 biofilms Erastin solubility dmso grown in minimal media supplemented with 10 μM FeCl3 was studied and it was observed that although supplementation with 10 μM FeCl3 resulted in significant enhancement of biofilm growth but addition of 500 μM chelator alone exerted minimal inhibitory effect on biofilm growth in comparison to control wells containing no iron or chelator. When a combination of 10 μM FeCl3 and 500 μM CoSO4 was added together, there was a significant decrease (p < 0.05) of ~2 logs in the younger biofilms till 3rd day but the reduction decreased to ~ 1 log from 5th day onwards for the older biofilms in comparison to the control wells containing no FeCl3 and CoSO4 (Figure 2).

We assessed assay specificity using megablast against human and bacterial sequences from the Genbank nucleotide collection (nr/nt) [34].   B Collection

of 18S rRNA gene sequence for in silico coverage analysis. From SILVA Release 108, we downloaded the sequences, sequence ID, and Genbank accession numbers of all fungal 18S rRNA gene sequences with sequence quality score of >90 and are 1,400 bp or longer [32]. We extracted the full Genbank taxonomy for each sequence, which we concatenated (e.g., at order-level, a taxonomic identification consists of phylum-subphylum-class-order). We replaced empty data fields in the concatenated Lazertinib manufacturer taxonomy with “unknown”, when applicable.   C Overview of in silico assay coverage analysis.

We performed the in silico coverage analysis using a stringent and a BIX 1294 nmr relaxed criterion, where the stringent criterion requires full perfect match of both primers and the relaxed criterion requires perfect match of the last eight nucleotides at the 3’ end of the primers. Both conditions require full perfect match of the probe sequence. For each condition, we determined the assay’s numerical and taxonomic coverage at the phylum, sub-phylum, class, order, family, genus, and species levels. Details for the in silico coverage analysis can be found in the Additional file 1: Methodological Details.   Quantification and normalization of FungiQuant plasmid standards We utilized a qPCR-based approach to quantify and normalize the FungiQuant plasmid standards, a C. albicans 18S rRNA gene clone, to a Cp-value equivalent to 109 copies/μl. Details for FungiQuant plasmid normalization can be found in the Additional file 1: Methodological CYTH4 Details. FungiQuant optimization and specificity check After testing multiple primer and probe concentrations, the optimized conditions included 10 μl and 5 μl of reaction volumes using 1 μl of template, with the final reaction containing 1.8 μM of each forward and reverse primer, 225 nM the TaqMan® probe, 1% Tubastatin A formamide, 1X Platinum® Quantitative PCR SuperMix-UDG

w⁄ROX (Invitrogen Corp.) and molecular-grade water. We included an in-run standard curve (25 copies, 50 copies, and 102-107 copies in 10-fold serial dilutions) and no-template controls in each run, with all reactions performed in triplicates on the 7900HT Real Time PCR System (Applied Biosystems). We used the following PCR conditions: 3 min at 50°C for UNG treatment, 10 min at 95°C for Taq activation, 15 s at 95°C for denaturation and 1 min at 65°C for annealing and extension x 50 cycles. We determined the Ct-value for each reaction using a manual Ct threshold of 0.10 and automatic baseline in the Sequence Detection Systems v2.3 software (Applied Biosystems). Using the optimized assay condition, we tested FungiQuant against 0.5 ng, 1 ng, 5 ng, and 10 ng of human genomic DNA (Promega, Madison, WI, USA) mixed with the normalized plasmid standards in triplicate reactions.

The latter appears to be a good candidate for activating AZD6244 in vivo the IKK (inhibitor kB kinase) signalosome proteins, which in turn phosphorylate the Relish (Rel family) transcriptional factor. The A-769662 cost second pathway controls the cleavage of Relish. The “Drosophila Fas-associated death-domain-containing protein” (dFADD), which is homologous to the mammalian adaptor protein that interacts with the complex “tumor necrosis factor receptor 1” (TNF-R1) to recruit pro-caspase-8, links IMD to the caspase “death-related ced-3/Nedd2-like” (DREDD) in order to build the “adaptor” complex that allows the activation of caspases and apoptosis [26, 27]. This pathway may end with a proteasome-independent

proteolytic cleavage of Relish, probably by the DREDD protein [28, 29]. The Relish cleavage dissociates the Rel and the Ankyrins and allows for processing of the nuclear transcriptional factor. To investigate immune and cellular processes in the

bacteriome tissue, we have used cereal weevils as a symbiotic system [6, 30]. These crop pests include three species (i.e. Sitophilus oryzae, Sitophilus zeamais and Sitophilus granarius) that all have in common an intracellular symbiosis with a Gram-negative γ-Proteobacterium, called Sitophilus primary endosymbiont (or SPE) [31, 32]. Sitophilus insects provide https://www.selleckchem.com/products/repsox.html an interesting system for studying host immune responses to symbionts as their association with SPE was established relatively recently (less than 25 MY ago), probably by endosymbiont replacement [11, 12, 17]. The endosymbiont genome has not experienced severe gene deletion [17,

33]. It encodes functional secretion systems [34] and genes encoding cell wall elements (unpublished data). Using suppressive subtractive hybridization (SSH), we have already identified several immune-relevant genes of S. zeamais species and we have demonstrated that weevil bacteriomes exhibit a specific local immune expression that allows symbiont persistence within the bacteriocyte cells [6]. Here, we have studied the sibling S. oryzae species. We have enlarged the panel of genes potentially involved in host-symbiont interaction through the construction and the sequencing of Rucaparib mw 7 different libraries from whole larvae and from bacteriomes (i.e. SSH, non-normalized and normalized libraries). Bioinformatic analysis of 26,886 ESTs has generated 8,941 unigenes. The results of qRT-PCR experiments strongly support the gene expression profile previously reported for the S. zeamais bacteriome [6], uncover new genes involved in the immune system, apoptosis, vesicular trafficking and cell-growth in the bacteriome tissue, and broaden the proposal that endosymbiosis may influence the host immune response in long-term host-symbiont coevolution.

Expired gas composition and temperature, HR, ambient

temperature and humidity during whole TT were monitored using Cortex MetaMax® 3B System and Polar 725 heart rate monitor. Carbohydrate (CHO) and fat utilization was calculated based on the equation built in the software by selecting an assumed 15% total energy expenditure derived from protein. AZD3965 datasheet The rating of perceived exertion (RPE) using the 6-20 Borg scale was surveyed at 20-min intervals throughout the test. The pre- and post-testing body mass (BM) with removal of their racing suit was checked using an electronic BM scale. Urine sample was collected during 10-min relax time of the performance test for volume determination. To ensure subjects were enthusiastic about the test and performed at their highest level, they were informed at the beginning of the test that a prize would be awarded to the winner cycling the longest distance

during TT. Blood samples collection and biochemical measurements Venous blood was collected from anticubital arm vein into vacutainer tubes before the performance tests. Heparin 4-Hydroxytamoxifen mw Plasma and serum were obtained after centrifugation at 3000 × g for 10 min. Samples were stored at -80°C until analyses. Finger blood was obtained via puncture for glucose determination at 0, 60, 125 and 155 min during the test. Free fatty acid (FFA), pyruvic acid (PA), and total antioxidant capacity (TAOC) in plasma were determined using commercial kits for (Randox Laboratories Ltd, Crumlin, UK), and an auto-biochemical Bucladesine price analyzer (Hitachi, Tokyo, Japan). Plasma VE, malondialdehyde (MDA) and arginine levels, xanthine oxidase (XOD) and glutathione peroxidase (GPx) and superoxide dismutase (SOD) and creatine kinase (CK) activities, and blood urea nitrogen (BUN) and nitric oxide (NO) were measured using spectrophotometric kits (Jiancheng Bioengineering Institute, Nanjing, China). Serum insulin (Ins) and

cortisol (Cor) concentrations were measured using radioimmunoassay kit (Jiuding Diagnostic, Tianjin, China). Blood glucose (BG) was determined using handheld blood glucose analyzer (One Touch, LifeScan, Inc. Milpitas, CA). Diet and dietary record All subjects lived in a winter training camp and dined in the same canteen throughout the study, and were advised by a registered dietician to follow a diet with 60% total calories from CHO, 15% from protein, and 25% from fat for 2 days before each performance test. Generally subjects had a typical Chinese breakfast consisting of one chicken egg, two servings of steamed breads or noodles, deep-fried dough sticks, rice congee, bean milk, some meat, some vegetables and appetizers, and lunch and dinner consisting of meat, steamed rice, steamed breads, noodles, soup, milk, fruit and vegetables, etc. To assess dietary intake throughout the study, a 2-day food record was conducted at week 2, 4, 8, and 10.

For each 1 μg of DNAse I-treated RNA, 50 ng of random

hexamers (Invitrogen) and 10 nM of each deoxynucleoside triphosphate (dNTPs, AZD6094 ic50 Bioline) were added and the mixture incubated at 65°C for 5 min, then immediately cooled on ice. To this, 4 μl of 5 x first strand reaction buffer (Invitrogen) and dithiothreitol (Invitrogen) to a final concentration of 0.1 M were added and the mixture incubated at 25°C for 2 min, then 1 μl (200 U) of Superscript II reverse transcriptase (RT) (Invitrogen) was added and Transmembrane Transporters inhibitor the reaction incubated for 10 min. A negative control (no RT) was also included, with 1 μl of RNase-free water substituted for the Superscript II reverse transcriptase. The reverse transcription reactions were incubated at 42°C

for 50 min. The reaction was stopped by incubation at 70°C for 15 min and the total volume made up to 600 μl with nuclease-free water and aliquots stored at −20°C. Each qRT-PCR reaction was conducted in a 20 μl volume and contained 5 μl template cDNA, 10 μl of 2 x Platinum SYBR Green qPCR Supermix containing Rox Dye (Invitrogen) and 100 nM each of the PRTF and PRTR primers (Table 1). Reactions 3-MA supplier were run using a Stratagene MX3000P. Each assay included test cDNA, the no-RT control reaction previously described and a no template control, to which only water was added. The cycling conditions were an initial incubation for 2 min at 50°C, followed by 5 min at 95°C, then 40 cycles of 95°C for 30 s and 60°C for 30 s. Reactions were carried out in triplicate for each sample. Relative quantification of phoA transcription was normalised against transcription from the glyceraldehyde 3-phosphate dehydrogenase gene Hydroxychloroquine (GAPDH, GeneID: 1090024) using the HLF and HMR primers (Table 1) and the relative level of expression calculated

using the delta-delta Ct method [41]. Detection of alkaline phosphatase activity in cultured cells Mycoplasma transformants were grown in 10 ml MB supplemented with gentamicin at 16 μg/ml until an approximate pH of 7.2 was reached, then pelleted by centrifugation at 20,000 x g for 20 min at 4°C. The cells were resuspended and washed twice in ice-cold 0.05 M Tris, pH 8.0 (T buffer) and again centrifuged and washed as before. The cells were finally resuspended in T buffer with 1% Triton X-100 (ICN) added and incubated for 15 min at 4°C. The total protein concentration of the cell lysate was determined in triplicate using a BCA kit (Pierce) following the manufacturer’s instructions. To determine the AP activity of each transformant in triplicate, 10 μl of the cell lysate was added to reaction buffer (1 M Tris, pH 8.0, 1 mM MgCl2) to which 50 μl of 2 mM disodium p-nitrophenyl phosphate (pNPP, Calbiochem) in reaction buffer was added and the mixture incubated at 37°C for 30 min. The reaction was terminated by addition of 100 μl 2 M NaOH and the absorbance read at 410 nm using a spectrophotometer (Labsystems Multiskan MS).
