The seasonal access of ASW beneath the FIS was first observed by Hattermann et Vemurafenib order al. (2012), and a similar seasonality of basal melting seen in the ANN-100 experiment was suggested by coarser model simulations using isopycnal coordinates (Nicholls et al., 2008). While the smoothed topography in ROMS may lead to an overestimate of upper ocean contribution to melting beneath the

FIS, sensitivity studies with the idealized setup of Zhou et al. (2014) suggest that the inflow of ASW is indeed a realistic feature of the simulations. In their experiments with different ice shelf geometries, the amount of ASW entering the cavity is largely independent of the shape of the ice front, and occurs when the wind-driven deepening of the ASW layer outside the cavity exceeds the depth selleck chemicals of the ice draft. Nevertheless, numerical artifacts associated with the terrain following coordinates cannot be ruled out in this setup. Quantifying the exact contribution

of upper ocean Mode 3-type of melting, and scrutinizing its sensitivity to varying forcing, thus remains subject to future work. The idealized simulations of Zhou et al. (2014) also show that the effect of the ASW on the frontal dynamics is a robust result and not an artifact of the hydrographic nudging at the periodic model boundary, a potential criticism in our model. Their annual experiments reproduce a similar deepening of the ASW and a shallower thermocline near the coast, although the ASW is exclusively introduced at the ocean surface. The realism of our simulations is challenged by the simplifications that are necessary to compromise the resolution of mesoscale eddies in a compact periodic domain, the limited amount of data available to construct the model forcing and boundary conditions, and the desire to limit the model’s complexity for the process-oriented sensitivity studies. Time-varying winds (Graham et al., 2013) and the modulating mechanical

effect of sea ice (Nunez-Riboni and Fahrbach, Thiamet G 2009) are likely to modify the short-term and seasonal variability seen in the ANN-100 experiment. The effects of a reduced momentum transfer during the maximum sea ice extent in winter could possibly be inferred from the experiments with different constant wind forcings, but a main challenge will be to better understand the ambiguous role of sea ice during transition between fully ice-covered and open-water conditions (Lüpkes and Birnbaum, 2005). To investigate the effect of time-varying winds, we conducted an additional test run with the 6-hourly RACMO2 wind stress applied. Compared to the constant-wind scenario, this run shows more variability of the coastal current and enhanced deep and shallow melting by about 10 cm year−1 for the entire ice shelf. But this simulation also features more MWDW inside the ice shelf cavity than shown by the observations.

Table 1 documents the results of the phantom tests. The navigator gated acquisition using respiratory trace 6 failed due to a very low respiratory efficiency (13%) which resulted in the respiratory trace exceeding the maximum length. For the remaining five respiratory traces, B2B-RMC resulted in a significant increase in vessel sharpness compared

to both uncorrected acquisitions (1.01±0.02 mm−1 vs. 0.71±0.10 mm−1, P<.01) and navigator gated acquisitions (1.01±0.02 mm−1 vs. 0.86±0.08 mm−1, P<.05). The measured vessel diameter was reduced (from 3.06±0.52 mm uncorrected) using both navigator gating (2.74±0.12 mm, P=not significant [ns]) and B2B-RMC (2.60±0.02 mm, P=ns), but the differences were not significant. The diameter obtained from the stationary images (2.60 mm) was similar to the average value using ALK targets B2B-RMC. The respiratory efficiency for the B2B-RMC acquisitions was 100% in every case, and the mean respiratory efficiency

for the navigator gated acquisitions was 46%±17%. Examples of the results from two of the acquisitions are shown in Fig. 4 (using trace 3 [4.A] and trace 6 [4.E]). In both cases, B2B-RMC demonstrates a substantial visual improvement (4.C and ABT-199 purchase 4.G) with improved vessel diameter and sharpness over the uncorrected images. For trace 3, navigator gating also demonstrates improved visual image quality, vessel diameter and vessel sharpness compared to the uncorrected data (4.D), while the navigator gated acquisition failed for trace 6, as described above. High-quality right coronary artery images were obtained in 10 subjects with both the B2B-RMC and nav-bSSFP techniques. Example images from one subject using both methods are shown in Fig. 5. Respiratory efficiency of the B2B-RMC technique was near 100% and significantly

higher than that of Protirelin the nav-bSSFP technique (99.7%±0.5%, range 98.4%–100% vs. 44.0%±8.9%, range 33.0%–62.8%; P<.0001). Vessel diameter and sharpness were successfully measured for the proximal vessel in all 10 subjects. One subject had a particularly small and tortuous vessel which could not be accurately measured in the midsection using either technique, and as a result, midsection vessel sharpness and diameter were obtained in 9 subjects. The sharpness and diameter measurements are summarized in Table 2 together with the average respiratory efficiency of both techniques. Vessel sharpness measured in both the proximal and mid vessel was not significantly different between the two methods. Vessel diameter in the mid artery was not significantly different, and although there is a significant difference in the proximal diameter, it is not substantial (0.15 mm or ∼5%).

Patients

who underwent SLUB were identified in a prospectively collected database. A standardized technique and protocol was applied. All patients underwent www.selleckchem.com/products/BIRB-796-(Doramapimod).html prior EUS by a 12 MHz catheter ultrasound probe. A 20mm mini-detachable loop was “prelooped” at the rim of an 18 mm diameter soft oblique transparent cap attachment. SLUB procedure: 1) Suction to draw the SET into the cap; 2) Ligation below the tumor, confirmed by repeat miniprobe EUS; 3) Unroofing of the overlying tissue with a needle knife; 5) Biopsies from the exposed tumor. The SLUB technique was attempted in 16 patients (2 males; median age 62) and successful in all. Location: 14 in stomach, 2 in colon. Median size by EUS: 10mm. Immunohistology: GIST- 4; leiomyoma-5; Carcinoid-3; Vanek’s tumor-2; Granuloma-1; Heterotopic fundic glands -1. Five patients (31%) had follow up with confirmation of tumor ablation by endoscopy and EUS. Complications: pain in 1; there was no bleeding or perforation. 1) Mini-loop ligation of small broad-based SETs is feasible; 2) Unroofing after ligation is safe and provides sufficient tissue for immunohistolochemistry; 3) Ligation combined with unroofing appears to lead to complete ablation by ischemia and tumor enucleation. A. Small broad-based subepithelial selleckchem tumor in the gastric body. B. Mini-loop ligation using the 18mm transparent ‘EMR’ cap. C. Post-ligation unroofing with a needle knife. Biopsies showed a GIST. D. Scar at site of loop

“Direct cholangioscopy offers diagnostic and therapeutic options beyond ERCP for complex biliary disease. Balloon-assisted cholangioscopy (BAC) is an exciting advance because of improved image quality and lower costs. Most studies however, have been in Asian subjects with bile ducts over 8mm. To assess feasibility of BAC in complex biliary disease in a multi-ethnic, largely non-Asian patient cohort tending to have smaller bile ducts. Either 4.9 or 5.5 mm endoscopes (Olympus

N180 or XP180) used. All subjects had a preceding sphincterotomy and/or balloon sphincteroplasty. Guidewire placement into the intrahepatic biliary tree was either by ERCP or under direct cholangioscopic vision. The balloon catheter was then advanced into the intrahepatic branches and inflated as an anchor Sclareol to allow cholangioscope passage. Visualisation was by saline irrigation with air for the initial 25 procedures and CO2 for the remaining 49. Biliary assessment was by white light and NBI, with targeted biopsies as required. Therapeutic procedures included APC and laser lithotripsy. Technical success was passage of the scope to the hilum or stricture. 57 patients (53 non-Asian) (25M, 32F) median age 69 (31-93) yrs underwent 74 procedures. Indications included assessment of indeterminate biliary strictures and masses, ampullary adenomas and difficult stone disease. Cholangioscopy was technically successful in 53 of 57 (93%) pts. Median procedure time was 30 (12-90) min and bile duct diameter 7 (2-20) mm.

9, 34, 35 and 36 The drug provides the enormous clinical benefit of preventing multiple pernicious and threatening attacks of acute malaria. Denying people access to this therapy undoubtedly imposes substantial and preventable burdens of morbidity and mortality, but providing it imposes risk of the serious harm. Practical and robust G6PD diagnostics at the point of care where most patients with malaria live would greatly mitigate this dilemma. The findings

reported here suggest that the CSG may be suitable for this diagnostic task. We detailed a robust means of assessing G6PD diagnostic devices in the laboratory with relative ease, simplicity, and low cost. The availability of G6PD screening in endemic Natural Product Library zones would likely add to the already substantial number of patients who cannot receive primaquine therapy—pregnant or lactating women and infants,37 among the most vulnerable to serious illness with acute vivax Adriamycin malaria.38 and 39 Further, some patients with relatively common mutations to 2D6 cytochrome P-450 may remain partially or fully susceptible to relapse despite primaquine therapy.40 These patients, including those screened out as G6PD deficient, will require alternative chemotherapeutic or chemopreventive strategies against relapse. Conceiving, optimizing, and validating such approaches should be

a very high clinical research priority. Baird JK, et al. Plasmodium vivax threatens 2.5 billion and causes >100 million clinical attacks, most originating from untreated forms in the liver. These are rarely treated because the only drug, primaquine, causes threatening acute hemolytic in patients having Protirelin an inborn deficiency in glucose-6-phosphate dehydrogenase (G6PD). We affirm noninferiority of a potentially important new clinical instrument—a G6PD deficiency test suitable for use where most patients with malaria live—compared with the laboratory standard test.

PBMCs responded differently in vitro to iHg, methyl Hg (MeHg), or ethyl Hg (EtHg). Both iHg and MeHg increased pro-inflammatory cytokine release while EtHg decreased pro-inflammatory cytokine release. These results indicate that both organic and inorganic species of Hg can

affect the human immune system, though they may exert different influences on immune function. In vivo, we found that Hg-exposed gold-miners with increased levels of biomarkers of autoimmune dysfunction (serum titers of antinuclear or antinucleolar autoantibodies) had significantly higher serum www.selleckchem.com/PI3K.html concentrations of the pro-inflammatory cytokines IL-1β, TNF-α, and IFN-γ as compared to a referent group of non-Hg exposed miners. Taken together, these results indicate consistent findings between in vitro and in vivo assessment of Hg immunotoxicity. Research supported by FNS-Brazil, Cure Autism Now, and NIEHS. “
“Cadmium (Cd) is a relatively rare toxic heavy metal and is found in the earths’ crust from 0.1 to 0.5 μg/g, and in the atmosphere from 0.1 to 5.0 ng/m3. Industrial activities, mainly zinc production and the use of Cd in pigments, plastic stabilizers, and batteries have significantly increased the amount of Cd in

the biosphere, and as a consequence Cd exposure of humans (The International Cadmium Association; www.cadmium.org). The major source for Cd uptake by (non-smoking) humans is food, and tobacco smoking approximately doubles the daily Cd uptake (ATSDR, 2009, Authority, 2009, Friberg and Ibrutinib price Nordberg, 1986 and Jarup

and Akesson, 2009). In the human body Cd has a half-life of 10–30 years and accumulates massively in organs like liver, kidney, and testes. Further, Abu-Hayyeh et al. demonstrated that also the vascular system is another target PRKACG organ for Cd deposition (Cd concentrations of up to 20 μM were observed in the aortic wall of heavy smokers) (Abu-Hayyeh et al., 2001, ATSDR, 2009, Satarug and Moore, 2004 and Staessen et al., 2001). In past decades the health threat of chronic low dose Cd exposure was underestimated. Accordingly, the European Food Safety Authority has reduced the provisional tolerable weekly intake from 7 μg/kg to 2.5 μg/kg in 2009 (Authority, 2011). Apart from the well known toxic effects of Cd on liver, kidneys and testis, the International Agency for Research on Cancer has classified Cd as a human carcinogen (Achanzar et al., 2001, Benbrahim-Tallaa et al., 2007, Benbrahim-Tallaa et al., 2009, CANCER, 1997, Joseph, 2009 and Waalkes, 2003), and recent studies, including ours, clearly indicate that Cd is also a significant risk factor for cardiovascular diseases (Messner et al., 2009 and Peters et al., 2010).

We will represent the visible layer activation variables by v  i, the hidden activations by h  j and the vector variables by v=viv=vi and h=hjh=hj where i=[1‥N]i=[1‥N] and j=[1‥S]j=[1‥S] index the individual neurons in the visible and hidden layers, respectively. Restricted Boltzmann Machines   are stochastic models that assume symmetric connectivity between the visible and hidden layers (see Fig. 1A) and seek to model the structure of a given dataset. They are energy-based models,

where the energy of a given configuration of activations vivi and hjhj is given by ERBM(v,h|W,bv,bh)=−v⊤Wh−bv⊤v−bh⊤h,and the probability of a given configuration is given by P(v,h)=exp(−ERBM(v,h|W,bv,bh))/Z(W,bv,bh),where Z(W,bv,bh)Z(W,bv,bh) is the partition function. One can extend the

RBM to continuous-valued Doramapimod price visible variables by modifying the energy function, to obtain the Gaussian-binary RBM ERBM(v,h|W,bv,bh)=−v⊤σ2Wh+∥bv−v∥22σ2−bh⊤h.RBMs are usually trained through contrastive divergence, which approximately follows the gradient of the cost function CDn(W,bv,bh))=KL(P0(v|W,bv,bh)||P(v|W,bv,bh))−KL(Pn(v|W,bv,bh)||P(v|W,bv,bh)),CDn(W,bv,bh))=KL(P0(v|W,bv,bh)||P(v|W,bv,bh))−KL(Pn(v|W,bv,bh)||P(v|W,bv,bh)),where Selleckchem MG132 P  0 is the data distribution and P  n is the distribution of the visible layer after n   MCMC steps ( Carreira-Perpinan and Hinton, 2005). The function CD  n gives an approximation to maximum-likelihood (ML) estimation of the weight matrix ww. Maximizing the marginal probability P(vD|W,bv,bh)P(vD|W,bv,bh) of the data vDvD in the model leads to a ML-estimate which is hard to compute, as it involves averages over the equilibrium distribution P(v|W,bv,bh)P(v|W,bv,bh). The parameter update for

an RBM using CD learning is then given by Δθ∝〈∂ERBM∂θ〉0−〈∂ERBM∂θ〉n,where the <>n<>n denotes an average over the distribution Pn of the hidden and visible variables after n MCMC steps. The Dynein weight updates then become ΔWi,j∝1σ2〈vihj〉0−1σ2〈vihj〉n.In general, n=1 already gives good results ( Hinton and Salakhutdinov, 2006). Autoencoders   are deterministic models with two weight matrices W1W1 and W2W2 representing the flow of data from the visible-to-hidden and hidden-to-visible layers, respectively (see Fig. 1B). AEs are trained to perform optimal reconstruction of the visible layer, often by minimizing the mean-squared error (MSE) in a reconstruction task. This is usually evaluated as follows: Given an activation pattern in the visible layer vv, we evaluate the activation of the hidden layer by h=sigm(v⊤W1+bh)h=sigm(v⊤W1+bh), where we will denote the bias in the hidden layer by bhbh. These activations are then propagated back to the visible layer through v^=sigm(h⊤W2+bv) and the weights W1W1 and W2W2 are trained to minimize the distance measure between the original and reconstructed visible layers.

Copepods and other zooplankton components were identified following Giesbrecht (1892), Williamson (1967), Heron & Bradford-Grieve (1995) and Conway et al. (2003). The three counts of total zooplankton at different depths and all seasons were treated statistically to determine the standard error and standard deviation of these counts. The surface water temperature varied seasonally

from a winter minimum of 22.8 °C to a summer maximum of 30.5 °C. The vertical thermal profile showed clear stratification in summer and slight differences during other seasons, whereas the vertical thermal difference within the epipelagic zone was small (Figure 2). Dissolved oxygen was relatively high in the surface water (6.6–7 mg l− 1) as well as within the epipelagic zone (5.3–7.8 mg l− 1), with some stratification during summer, autumn and winter, and distinct stratification in spring Metformin (Figure 3). In our study, maximum dissolved oxygen in E7080 cost spring coincided with the highest content of chlorophyll a within the depth range of 50–75 m, supporting the role of phytoplankton photosynthesis in the oxygenation of the water column. The phytoplankton biomass in the epipelagic zone exhibited low as well as moderate values over

the year, whereas concentrations of chl a fluctuated between 0.04 μg l− 1 at 100 m in spring and 1.12 μg l− 1 at 75 m, also in spring. The surface water was usually poor in phytoplankton, whereas the vertical profile displayed

slight variations during summer, autumn and winter, and displayed a clear subsurface chlorophyll high in spring ( Figure 4). The epipelagic zooplankton off Sharm El-Sheikh was composed HSP90 mainly of copepods, which constituted seasonally 78.6–93.2% of the total zooplankton with a mean of 86.5%. The molluscan larvae (gastropods and bivalves) were second in order of abundance, making up 2.6–15.2% with a mean of 7.6%, followed by appendicularians (1.4–3.7%, mean: 2.4%) and chaetognaths (0.7–1.6%, mean: 1.1%). Cnidarians demonstrated a comparatively small relative abundance (0.2–1.4%) in the total zooplankton. The contributions of the main groups to the total zooplankton during the present study (Table 1) were roughly similar to those reported in another study (ElSherbiny et al. 2007), but are more or less different from those found in the northern Gulf of Aqaba (Cornils et al. 2005). The zooplankton density during the present study showed relatively wide seasonal variations in the water column (∼ 1.1 × 103 − ∼ 5 × 103 organisms m− 3), with a conspicuously high density (4952 and 4445 organisms m− 3) within the surface layer (0–25 m) in summer and the 25–50 m depth range in spring. The standard error and standard deviation of total zooplankton density are given in Table 2. The vertical profile demonstrated decreasing zooplankton density with depth during all seasons, particularly in the deep layer from 50 to 100 m (Figure 5).

From the re-sampled population, a control group was then assigned to each experimental treatment group by random sampling of the control distribution. Selleckchem ABT263 The procedure was performed using the Re-sampling Stats v3.20 add-in for Microsoft Excel (Re-sampling Stats Inc., Arlington, VI, USA) and the random number generator application in the Data Analysis package of Microsoft Excel 2002 (Microsoft Canada Co., Mississauga, ON, Canada). Particle-induced and stimulant-induced respiratory burst data (luminescence, AUC) and the viability data (absorbance) were expressed as the ratio to the control

mean (fold effect). Data were expressed as mean fold effect ± SE for n = 3–5 independent experiments, with 1–3 technical replicates within each experiment. The re-sampled control (dose 0 μg/well) values are also displayed in Fig. 3, Fig. 4 and Fig.

selleck screening library 5. Where the data were not normally distributed or did not meet homoscedasticity, rank-transformation was applied prior to the ANOVA analysis. Data were analyzed by two-way ANOVA with particle (EHC-93tot, EHC-93insol, EHC-93sol, SRM-1648, SRM-1649, VERP, SiO2, TiO2, iron II/III oxide, iron III oxide, nickel II oxide, copper II oxide) and dose (0, 20, 50, 100 μg/well) as factors, followed by the Holm-Sidak multiple comparisons procedure to elucidate the patterns of significant effects (α = 0.05). The ANOVA analysis was performed using SigmaPlot 11. Exposure of macrophages for 2 h to the urban particles (SRM-1648, SRM-1649, EHC-93tot, EHC-93insol) and the mineral particles (TiO2, SiO2), prior to addition of the stimulants induced a mild respiratory burst (100–300 L.U.) over baseline (ca. 25 L.U.),

at most particle DNA ligase doses tested ( Fig. 3). EHC-93sol and the PM2.5 material VERP overall had minimal effects on the luminescence signal of the unstimulated cells, although a slight, statistically significant increase in luminescence over baseline was noted for VERP, as well as a small statistically significant decrease was observed for EHC-93sol at the 20 μg/well dose exposure ( Fig. 3, inset A). The iron II/III oxide, iron III oxide and copper II oxide materials caused a significant decrease of measured luminescence, while nickel II oxide did not significantly alter the luminescence signal (two-way ANOVA, particle × dose, p < 0.001) ( Fig. 3, inset B). The viability of the cells after this 2 h period of incubation with particles, as measured by the XTT reduction assay, was above 60% for the high dose (100 μg/well) and above 80–100% for the lower doses of the particles (Fig. 4A). Amongst metals, copper II oxide was exceptionally cytotoxic, with significant early cytotoxicity even at the lowest dose of particles (20 μg/well) tested. Similar patterns of XTT effects were observed at 2, 3, 7 h post-exposure (3 and 7 h data not shown).

Shark bycatch on FADs is almost exclusively composed of two species; silky sharks Carcharhinus falciformis and oceanic white tip sharks Carcharhinus longimanus, together comprising over 90% of the shark bycatch by number [21]. As with many sharks, these species have slow growth rates, mature late and have long reproductive cycles with few offspring, and as such are highly susceptible to population decline from excessive fishing pressure [22]. FADs in particular are also associated with the mortality of sharks and turtles through entanglement learn more with the net hanging beneath a raft (i.e. ghost fishing), although the extent of this mortality

is not usually estimated [23]. The reason for the natural aggregation of tunas beneath floating objects is not entirely clear although the two most credible explanations for this behaviour are the meeting point hypothesis [24] and the indicator-log hypothesis [19]. The meeting point hypothesis suggests that fish associate with

floating objects to facilitate schooling behaviour and subsequently benefit from this social interaction whilst the indicator-log hypothesis suggests that natural floating objects are indicators of productive habitat given that they originate from nutrient-rich areas (e.g. river mouths, mangrove swamps) and subsequently drift with these patches of productivity into the ocean. Given these possible explanations for the association of tunas with floating objects there is concern that the deployment of large numbers selleck of FADs in the pelagic ocean could change the natural environment of tunas, a theory known as the ‘ecological trap hypothesis’ [25] and [26]. Large numbers of floating objects could potentially modify the movement patterns of tunas and carry associated schools in ecologically unsuitable areas and thus affect their growth rate or increase fantofarone natural mortality and/or predation [26] and [27]. Although this subject has received considerable

research attention, it is difficult to evaluate the impacts of FADs on the ecology of tunas, largely due to uncertainty in how tunas interact with floating objects (e.g. length of association, reasons for joining/leaving an object). Consequently the ecological trap hypothesis remains open to discussion [5] and [9]. FADs have had a strong influence in shaping the spatial dynamics of the purse seine fishery. Floating objects are not distributed evenly throughout the western Indian Ocean and their location at any given time is determined largely by surface currents and winds. Floating logs and branches generally originate from large rivers and mangrove systems and drift with the currents throughout the coastal waters and potentially further offshore. This natural flotsam, which has always been a part of the ocean habitat of tuna, accumulates at particularly high densities in the Mozambique Channel where numerous river systems wash debris into the ocean [28].

Two patients in the 60-U/kg treatment group selleck screening library experienced 8 events that were considered to be treatment-related by the investigator; the first patient reported 3 occurrences of itchy throat and 1 occurrence of chest discomfort, and the second patient reported 1 occurrence of gastroenteritis and 3 occurrences of vomiting. Both patients were pre-medicated with H1 blockers and are continuing in the extension study. No patient withdrew from this trial due to an AE. No clinically significant laboratory test abnormalities (hematology,

serum and urinary chemistry) were noted. There were no clinically significant mean changes from baseline observed at the end of the study in any of the laboratory safety parameters. The majority of the vital sign measurements were within normal limits, none of the changes or the measurements outside of the normal limits were clinically significant. Abnormal echocardiography results at month 12 were reported for 2 patients: One patient receiving the 60-U/kg dose had mild tricuspid regurgitation and 1 patient in the 30-U/kg group diagnosed with Type 3c GD (subtype known to have a cardiac involvement) [1], [17] and [18] had a baseline echocardiography that revealed abnormal atrioventricular and mitral valves with

an insufficiency gradient of 30 mm Hg. At study end, the echocardiography results showed pulmonary hypertension with an abnormal tricuspid insufficiency gradient of 74 mm Hg, which was considered a clinically significant deterioration signaling pathway but was deemed not related to study treatment. Two patients were found to be IgG positive for anti-taliglucerase-alfa antibodies in at least 1 post-treatment visit; however, this finding did not affect the continued improvement of GD parameters throughout the course of the study. An additional patient was found to be IgG positive at the pretreatment sample and became negative as the trial progressed; this patient also improved clinically as noted above for the other 2 patients. All positive titers were low (< 550). Assay results for neutralizing antibodies (in vitro enzymatic inhibition assay and cell-based neutralizing

assay) were negative for all 3 patients. No apparent association was noted between anti-taliglucerase antibody and safety or efficacy. This study is distinguished among studies of ERT Glutathione peroxidase for GD in that it is focused exclusively on treatment-naïve pediatric patients. This pediatric study followed the design of the pivotal study in adults regarding dosage, wherein patients were randomized to receive taliglucerase alfa either 30 or 60 U/kg, every other week. However, in this study, the duration was 12 months instead of 9 months and the primary end point was improvement in hemoglobin rather than reduction in spleen volume. At the end of this study, clinically significant improvements were observed in hemoglobin concentration, platelet counts, spleen volume, and liver volume, as well as in GD biomarkers.
