Once the methods were optimized and validated, their application was evaluated with eight methanol plant extracts.
The DPPH free radical reduction method was carried out by mixing 100 μL of the plant extract sample at different concentrations (250–0.25 μg/mL ethanol) with 100 μL of DPPH (280 μM in ethanol). A negative control was included (corresponding to 100% DPPH) in which ethanol was added instead of the sample. The mixture was incubated in the dark for 15 min at room temperature, and then the absorbance was measured at 540 nm with a Multiskan FC microplate reader.
For the ABTS free radical reduction method, a 7 mM solution of ABTS in 2.45 mM aqueous potassium persulfate was prepared. The solution was incubated for 12–16 h in the dark to produce the ABTS+ free radical. This solution was diluted with ethanol to adjust the absorbance value to 0.7. To evaluate antiradical activity, 60 μL of a plant extract sample solution (150–0.25 μg/mL ethanol) was mixed with 140 μL of the ABTS+ solution (A=0.7). A negative control was included (corresponding to 100% ABTS) in which ethanol was added instead of the sample. The mixture was incubated in the dark for 6 min at room temperature and the absorbance was measured at 750 nm with a Multiskan FC microplate reader.
For both DPPH and ABTS, the calculations used to obtain the percentage reduction of the light-absorbing species were those used for the optimization and validation of the method (Eq. (1)). A linear regression plot was constructed using the respective percentage reduction from each sample. The EC50 was assessed by curve interpolation for each of the plant extract samples. The results were also expressed as Quercetin equivalents for DPPH (μmol QE/g of Fresh Weight) and Trolox equivalents for ABTS (μmol TE/g of Fresh Weight) using standard curves. Quercetin standard solutions were prepared at concentrations from 1.65 to 26.47 μM and the t concentration of Trolox standard solutions ranged from 1 to 23.97 μM.

All animal studies were conducted in accordance with the guidelines
approved by the Institutional Animal Care and Use Committees at the University
of Texas MD Anderson Cancer Center. Twenty female NOD SCID gamma (NSG) mice
(6-wk old, Jackson Laboratory, Bar Harbor, MA) were intravenously injected with
luciferase-labeled MOLM-13 cells (0.7 x 106 cells/100 μL) and
randomly divided into two groups. Four days post injection, the mice were
treated with vehicle or ABT-199 (100 mg/kg body weight) daily by oral gavage for
2 weeks. For oral dosing, ABT-199 (10 mg/mL) was formulated in 60%
phosal 50 propylene glycol, 30% polyethyleneglycol-400, and 10%
ethanol. Bioluminescence imaging (BLI) was used to monitor tumor burden on
different time points. Briefly, mice were anaesthetized and injected
intraperitoneally with firefly luciferase substrate D-luciferin and then imaged
noninvasively using IVIS-200 in vivo imaging system
(PerkinElmer, Waltham, MA). Three mice from each group were sacrificed by
CO2 asphyxiation after 15 d. Bone marrow, spleen, and liver were
collected for H&E and immunohistochemical staining. The remaining seven mice
in each group were followed for survival.
For primary AML derived xenograft models, NSG mice were sub-lethally
irradiated (250 cGy) the day prior to intravenous injection of 105PDX21 patient-derived AML cells. Three weeks following injection and after
confirmation of AML engraftment, the mice were randomly divided into two groups
and treated with 100 mg/kg ABT-199 or vehicle via gavage daily for 2 weeks. All
mice were then sacrificed and femur bone marrows were analyzed for leukemia
burden by CD45 flow cytometry (using anti-human CD45-PE antibody
#555483, BD Biosciences, San Jose, CA).

Preliminary titrations with varying antigen concentrations, serum and secondary antibody dilutions were conducted to determine optimal conditions to carry out the enzyme-linked immunosorbent assay (ELISA) using sera from endemic normal people (i.e. heavily exposed to infection but negative for schistosome eggs), negative controls (i.e. British people who had never travelled to schistosome endemic areas) and a pool of sera from the whole population. These titration assays allowed determination of the serum dilution and antigen concentration yielding the best discrimination between negative and positive controls. The Elisa protocol was thus developed. Assays were conducted using MBP-Sh13 and MBP control as is standard [3 (link)]. ELISA plates (Nunc-Immulon, Denmark) were coated with 100 μl/well of 1 μg/ml antigen in 60 mM carbonate-bicarbonate buffer (pH 9.6) and incubated overnight at 4°C. Plates were blocked with 200 μl/well of skimmed milk (5% milk in phosphate buffered saline (PBS)/0.03% Tween 20) for 1 hr and washed three times in PBS/Tween 20, which was used for all washes. 100 μl of serum was added to each well at 1:100 dilution; plates were incubated overnight at 4°C and then washed three times. 100 μl of isotype-specific monoclonal antibody was added at 1:1000 dilution for the detection of IgA (Dako, Denmark, P0216), IgE (Vector Laboratories, UK P0720), IgG1, IgG2, IgG3, IgG4 (The Binding Site, UK, AP006, AP007, AP008 and AP009, respectively) and IgM (Dako, Denmark, P0215). Plates were incubated overnight at 4°C, washed six times and 100 μl of ABTS substrate solution (KPL, Canada) was added. The IgE-specific antibody was biotinylated; so 100 μl/well of streptavadin-horseradish peroxidase (Amersham, UK) was added at 1:6000 dilution to these plates, which were then incubated for 1 hr at 37°C, washed 6 times and developed. The reaction was allowed to take place at 37°C for 30 min for all isotypes, before the absorbance was read at 405 nm. Three negative controls used in the titration assays were included on each ELISA plate and all samples were assayed in duplicate.
For comparative purposes, antibody assays were also conducted with the conventional crude worm antigen (soluble worm antigen preparation, SWAP) prepared following standard protocols [13 (link)]. These assays were conducted following the same protocol as above using 1 μg/ml SWAP to coat the plates (a random subset of 41 samples run using 20 μg/ml SWAP together with negative and positive controls showed that similar results were obtained using 1 μg/ml and 20 μg/ml of SWAP) sera diluted at 1:100, and secondary antibodies diluted at 1:1000 for IgG1 and 1:500 for IgG2, IgG3, IgG4.

Beginning after fibrosis was established (4 weeks after silica or 10 weeks after the initial bleomycin dose), mice were administered 100 mg/kg ABT-263 in DMSO and sterile corn oil or vehicle (sterile corn oil with DMSO) by daily oral gavage for 28 days. Mice underwent micro-CT scanning prior to the induction of fibrosis, prior to treatment with ABT-263, and at study termination (Skyscan 1276, Bruker MicroCT). Images were acquired at 35 μm resolution, with x-ray tube voltage 50 kV, current 500 A, exposure time 900 ms, with 0.5 mm aluminum filter and a 0.7° rotation step. Scans were reconstructed as described (29 (link)). Fibrosis was assessed by measuring nonaerated lung tissue volume by micro-CT, lung collagen quantified by hydroxyproline in the upper right lobe (12 (link), 29 (link)), and semiquantitative stereology-based point-counting assessment of fibrosis in the left lung of formalin-fixed, paraffin-embedded, 5 μm sections stained with Masson’s trichrome and imaged by Aperio Scanning (Leica Biosystems) (74 (link)). PDGFRα+ fibroblast numbers were measured by flow cytometry (12 (link)).

AA was determined using the ABTS reagent following the method described by Ozgen et al. [55 (link)]. Briefly, 100 µL of the extracts at different dilutions factors were placed in a 96-well plate and mixed with 100 µL of ABTS reagent (prepared in methanol). The mixture was kept in the dark for 10 min and the measurement was performed at 515 nm in a microplate reader (BMG LABTECH, Ortenberg, Germany). For the quantification of AA, a calibration curve prepared in Trolox, covering a concentration range between 3 and 31 mg/L (absorbance between 0.200–0.800), was employed. The AA was expressed as millimoles Trolox equivalent per liter of the extract (mmol TRE/L).
The mean inhibitory concentration (IC50) of the samples was also calculated, represented as the milligrams of dry alga per litre of extract (mg·L−1) necessary to inhibit 50% of the ABTS radicals [56 (link)]. For this purpose, 8 concentration levels of the extract were carried out in a range of inhibition between 20% and 80% of ABTS+. In this way, it interpolates in the linear range close to 50% by means of the relationship
Y=aX+b
where:
Y” is the percentage inhibition of ABTS+.
