“Most of solid tumor cells are hypoxic and hard to trace and measure. A new compound, 4,7-bis(4-dodecylthiophen-2-yl)-5,6-dinitrobenzo[c][1,2,5]thiadiazole (BTTD-NO2), was LY3039478 cost synthesized for labeling the hypoxic cells specially in this paper. BTTD-NO2 showed no cytotoxicity to MG63 cells by MTT method. When MG63 cells were cultured with BTTD-NO2 under hypoxic condition for 24 h, strong red fluorescence distribution in cytoplasm was observed. Flow cytometry results showed that 65% of MG63 cells were labeled with strong red fluorescence in hypoxic condition while only 2.4% in oxic condition. Furthermore, Real time RT-PCR proved that BTTD-NO2 could stimulate high gene expression of the nitroreductase

in the cells which could improve the conversion rate of BTTD-NO2 to BTTD-NH2 in turn. It proved that the fluorescence of BTTD-NO2 was quenched by its two nitro groups, however, strong red fluorescence could emit in the cytoplasm after the reduction of its nitro groups to amino groups in the tumor cells under hypoxic condition. These results suggested that BTTD-NO2 had the potential as a superior fluorescent probe for tumor detection. (C) 2013

“P>O-mannosylation is a crucial protein modification in eukaryotes that is initiated by the essential family of protein O-mannosyltransferases (PMTs). Here we demonstrate that in the BTSA1 CRT0066101 purchase model yeast Saccharomyces cerevisiae rhodanine-3-acetic acid derivatives affect members of all PMT subfamilies. Specifically, we used OGT2468

to analyse genome-wide transcriptional changes in response to general inhibition of O-mannosylation in baker’s yeast. PMT inhibition results in the activation of the cell wall integrity (CWI) pathway. Coinciding, the mitogen-activated kinase Slt2p is activated in vivo and CWI pathway mutants are hypersensitive towards OGT2468. Further, induction of many target genes of the unfolded protein response (UPR) and ER-associated protein degradation (ERAD) is observed. The interdependence of O-mannosylation and UPR/ERAD is confirmed by genetic interactions between HAC1 and PMTs, and increased degradation of the ERAD substrate Pdr5p* in pmt Delta mutants. Transcriptome analyses further suggested that mating and filamentous growth are repressed upon PMT inhibition. Accordingly, in vivo mating efficiency and invasive growth are considerably decreased upon OGT2468 treatment. Quantitative PCR and ChIP analyses suggest that downregulation of mating genes is dependent on the transcription factor Ste12p. Finally, inhibitor studies identified a role of the Ste12p-dependent vegetative signalling cascade in the adaptive response to inhibition of O-mannosylation.”
“P>Glial cell line-derived trophic factor (GDNF) is a peptide with pleiotropic survival and growth-promoting effects on neurons.

After therapy, the labeling index in groups 1 and 2 decreased to 18.60 +/- 1.18 and 14.38 +/- 0.81%, respectively. Histologically, normalization of the disease symptoms

was more pronounced after combination therapy. The decrease in free radical oxidation in this group of patients was more pronounced than after mesalazine monotherapy. Our results suggest that oxidative stress plays a role in the hyper-regenerative reaction.”
“PlexinA4 is the latest member to be identified of the PlexinA subfamily, critical transducers of class 3 semaphorin signaling as co-receptors to neuropilins 1 and 2. Despite functional information regarding PF-03084014 inhibitor the role of PlexinA4 in development and guidance of specific neuronal pathways, little is known about its distribution in the adult central nervous system (CNS). Here we report an in depth immunohistochemical analysis of PlexinA4 expression in the adult rat CNS. PlexinA4 staining was present in neurons and fibers throughout the brain and spinal cord, including neocortex, hippocampus, lateral hypothalamus, red nucleus, facial nucleus, and the mesencephalic trigeminal nucleus. PlexinA4 antibodies labeled fibers in the lateral septum, nucleus accumbens, several thalamic nuclei, substantia nigra pars reticulata, zona incerta, pontine reticular region, as well as in several cranial nerve nuclei. This constitutes the first detailed description of the topographic distribution

of PlexinA4 in the adult CNS and will set the basis for future studies on the functional implications of PlexinA4 in adult brain physiology.”
“Contraceptive properties of seaweeds are still stands as Bafilomycin A1 clinical trial lacuna; in this context, the screening of in vitro male contraceptive properties of crude ethanolic extract of Indian QNZ cost seaweeds against normal human sperm is carried out. In total, twelve seaweeds were screened for in vitro spermicidal activity. Among these twelve seaweeds, Halimeda gracilis showed 100% inhibition of human spermatozoa at 10mgml(-1) concentration in 20s and its EC50 value was 2.05mgml(-1) in 20s. Further, dose- and time-dependent

spermicidal assay revealed that the sperm was completely immobilised for 20s. Plasma membrane of sperm was damaged due to the exposure of H.gracilis extract. MTT assay with H.gracilis extract showed 88.5% of cytotoxic incidence. H.gracilis extract tested for cytotoxicity against Artemia salina recorded LC50 value of 34.8gml(-1). Phytochemical analysis of H.gracilis extract evidenced the presence of alkaloids, flavonoids, proteins and sugars. Results of this study clearly inferred that the synergistic effect of active principles reside within the H.gracilis extract had shown better contraceptive activity.”
“OBJECTIVE: To analyze the role of a Municipal Health Ombudsman and its contribution to the public health management from the perspective of the public health system users and the municipal health counselors.

A strong acid phosphatase reaction was evident in the endothelium. BPB reaction for protein was moderate to intense. Ducts and acini were PAS and Alcian Blue reactive. The reaction for glycogen and AMPS contents in the gland increased with age. It was very intense in the pubertal animals. Moderate DNA activity, mild to moderate alkaline and acid phosphatases in the glandular acini and ductal epithelium revealed functionally active secretory glands particularly in the pubertal animals.”
“The broad-spectrum antitumor agent 5-fluorouracil (5-FU), has been used to treat various solid malignant tumors. However, its short life-time in vivo and poor ability to cross the see more blood-brain

barrier has limited its application to brain tumor therapy. In order to develop a 5-FU derivative that localizes efficiently to the brain while retaining potent antitumor activity, we conjugated 5-FU with N,N-dimethylethylenediamine via an amide bond. The stability of the resulting 5-FU derivative (D-FU) was tested in vitro in phosphate buffer, rat plasma and brain homogenate. The pharmacokinetic and biodistribution studies in brains of the rats showed a higher C-max (the maximal concentration) and an increased AUC(0-t) (the area under the concentration-time curve) which was 6-fold that of 5-FU. In addition, compared to 5-FU, D-FU exhibited lower toxicity in an acute toxicity

assay and similar antitumor activity in the C6 cell line. In conclusion, D-FU has the potential to be developed into an efficient brain Selleck GS-7977 delivery drug.”
“Experimental tumor vaccination and adoptive T-cell find more therapies show that interferon-gamma (IFN-gamma)-producing CD4(+) T helper cells (Th1) can be highly effective in tumor prevention and therapy. Unexpectedly, first vaccine trials in humans revealed that tumor immune therapy may not only be protective, but, on the contrary, even promote tumor progression. Here, we analyzed T-cell immune responses to the epithelial cell adhesion molecule (EpCAM), one of the most common tumor-associated antigens (TAA) serving

as immune target in colon cancer patients. Th-cell priming against EpCAM inevitably resulted in interleukin-4 (IL-4)-dominated Th2 responses, even under most stringent Th1-inducing conditions. These EpCAM-reactive Th2 cells rather promoted growth of EpCAM-expressing tumors. To analyze the role of IL-4 in tumor immune evasion, we generated EpCAM-reactive Th1 cells from IL-4.ko mice. These Th1 cells provided tumor-specific protection and established highly protective Th1 memory responses, even in naive BALB/c mice. Inhibition of tumor growth by Th1 cells resulted in intratumoral expression of cytokines of the IL-12 family and of IFN-gamma. Preventing activation-associated death of Th1 cells further increased intratumoral IFN-gamma expression and improved therapeutic efficacy. Thus, human TAA may promote tumor immune evasion by strongly favoring Th2 development. (Blood.

For BCS patients life-long anticoagulant treatment is advised. In patients with PVT it is recommended to tailor treatment to the individual patient based on the presence of an underlying prothrombotic disorder and the risk of bleeding.”
“Geranylgeranoic acid (GGA), a 20-carbon acyclic polyprenoic acid (all-trans 3,7,11,15-tetramethyl-2,4,6,10,14-hexadecatetraenoic acid) and its derivatives were developed as synthetic “acyclic retinoids” for cancer chemoprevention. Previously, we have ICG-001 shown the natural occurrence of GGA in various medicinal herbs and reported enzymatic formation of GGA from geranylgeraniol (GGOH)

through geranylgeranial (GGal) by rat liver homogenates. Here, we present several lines of evidence that a putative GGOH oxidase is involved in GGA synthesis by human hepatoma cell lysates. First, conversion of GGOH to GGal did not require exogenous NAD(+), whereas the conversion from GGal to GGA absolutely required additional NAD(+). Second, GGal synthesis from GGOH MS 275 was coupled with consumption of oxygen from the reaction mixture. Third, GGOH-dependent GGal synthesis activity was proteinase K-resistant and even enhanced by proteinase K treatment; GGOH oxidase activity was enriched in the mitochondrial fraction. Finally, recombinant human monoamine oxidase (MAO)-B, but not MAO-A catalyzed oxidation of GGOH to

GGal. These data suggest that a putative mitochondrial GGOH oxidase is involved in the initial step of GGA synthesis from GGOH.”
“With its high prevalence and well-known thromboembolic risk, atrial fibrillation (AF) is a crucial component of the 2010-2014 actions plan, ongoing Crenolanib in vitro in France to reduce the annual incidence of stroke. The stroke risk is stratified well with the CHA(2)DS(2)-VASc score. With the current guidelines, most patients with AF should be on oral anticoagulant regimen, a treatment recognized as effective but whose bleeding risks limit its use. In clinical practice, warfarin is often not prescribed

in patients with high risk of stroke. Thus, the exploration of new ways in preventing thromboembolic events in patients with AF is needed. Beside new more convenient anticoagulant agents, the exclusion of the left atrial appendage recognized as main source of thrombi, may be an alternative in patients with both high risk of thrombotic and haemorrhagic events. Surgical experience showed that the results depend on the quality of the exclusion. For over the past 10 years, several percutaneous exclusion systems of the left atrial appendage have been developed. A randomized study (PROTECT AF) demonstrated the non-inferiority of the percutaneous exclusion in comparison with the warfarin. However, the place of this interventional therapy remains to be clarified, particularly the definition of the target population.

This in turn may affect the ability of the organism to detoxify endogenous and exogenous xenobiotics.”
“Dietary Selleckchem eFT-508 plant sterols have received increasing attention in recent years due to their favorable health benefits. The present research focused on quantification of phytosterols as free, esterified and total forms in different tetraploid (5 cultivars of Triticum durum Desf., 9 cultivars of Triticum dicoccon Schrank) and hexaploid (5 cultivars of T aestivum L., 12 cultivars of Triticum spelta L.) wheats. Tetraploid wheats showed the highest content of total sterol (79.4

and 79.5 mg of sterols /100 g dry weight for T durum and T. dicoccon, respectively). Hexaploid cultivars were the best source of esterified sterols (40.7% and 37.3% of total sterols for Triticum aestivum and T. spelta, respectively). Significant amounts of free sterols (65.5% and 60.7% of total sterols for T durum and T dicoccon, respectively) were found in the tetraploid cultivars. The most abundant phytosterol in all wheat samples was sitosterol accounting for 45.1-59.1, 46.6-57.4 and 38.6-59.5% of total, free and esterified sterol fraction,

this website respectively. These results demonstrate that although the sterol profile present in tetraploid and hexaploid wheat species is the same, differences in their relative amounts and distribution allow statistical differentiation between hexaploids and tetraploids, and between soft and durum wheats.”
“We discuss protein post-translational modification (PTM) from an information processing perspective. PTM at multiple sites on a protein creates a combinatorial explosion in the number of potential mod-forms, or global patterns of modification. Distinct mod-forms can elicit distinct downstream responses, so that the overall response depends partly on the effectiveness of a particular mod-form to elicit a response and partly on the stoichiometry of that mod-form in the molecular population. We introduce the mod-form distributionthe relative stoichiometries of each mod-formas the most Erismodegib informative measure of a protein’s state. Distinct mod-form distributions may summarize

information about distinct cellular and physiological conditions and allow downstream processes to interpret this information accordingly. Such information encoding by PTMs may facilitate evolution by weakening the need to directly link upstream conditions to downstream responses. Mod-form distributions provide a quantitative framework in which to interpret ideas of PTM codes that are emerging in several areas of biology, as we show by reviewing examples of ion channels, GPCRs, microtubules, and transcriptional co-regulators. We focus particularly on examples other than the well-known histone code, to emphasize the pervasive use of information encoding in molecular biology. Finally, we touch briefly on new methods for measuring mod-form distributions. WIREs Syst Biol Med 2012, 4:565583. doi: 10.1002/wsbm.

Patients inflicted with metabolic disorders also suffer from tissue repair defect. Mitsugumin 53 (MG53) is a protein essential

to cellular membrane repair. It facilitates the nucleation of intracellular 10058-F4 vesicles to sites of membrane disruption to create repair patches, contributing to the regenerative capacity of skeletal and cardiac muscle tissues upon injury. Since individuals suffering from metabolic syndrome possess tissue regeneration deficiency and MG53 plays a crucial role in restoring membrane integrity, we studied MG53 activity in mice models exhibiting metabolic disorders induced by a 6 month high-fat diet (HFD) feeding. Western blotting showed that MG53 expression is not altered within the skeletal and cardiac muscles of mice with metabolic syndrome. Rather, we found that MG53 levels in blood circulation were actually reduced. This data directly contradicts findings presented by Song et. al that indict MG53 as a causative factor for metabolic syndrome (Nature 494, 375-379). The diminished MG53 serum level observed may contribute

to the inadequate tissue repair aptitude exhibited by diabetic Selleckchem URMC-099 patients. Furthermore, immunohistochemical analyses reveal that skeletal muscle fibers of mice with metabolic disorders experience localization of subcellular MG53 around mitochondria. This clustering may represent an adaptive response to oxidative stress resulting from HFD feeding and may implicate MG53 as a guardian to protect damaged mitochondria. check details Therapeutic approaches that elevate

MG53 expression in serum circulation may be a novel method to treat the degenerative tissue repair function of diabetic patients.”
“Nanostructured cobalt doped ZnO thin films were deposited on glass substrate by sol-gel spin coating technique and characterized by X-ray diffraction, X-ray photoelectron spectroscopy, field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy and UV-Vis spectroscopy. The XRD results showed that the thin films were well crystalline with hexagonal wurtzite structure. The results of EDAX and XPS revealed that Co was doped into ZnO structure. FESEM images revealed that the films possess granular morphology without any crack and confirm that Co doping decreases the grain size. UV-Vis transmission spectra show that the substitution of Co in ZnO leads to band gap narrowing. The Co doped ZnO films were found to exhibit improved photocatalytic activity for the degradation of methylene blue dye under visible light in comparison with the undoped ZnO film. The decrease in grain size and extending light absorption towards the visible region by Co doping in ZnO film contribute equally to the improved photocatalytic activity.

In terms of stability it

has become customary to distinguish between obligate and non-obligate interactions dependent on whether or not the protomers can exist independently. In terms of spatio-temporal control protein interactions can be either simultaneously possible (SP) or mutually exclusive (ME). In the former case a network hub interacts selleck with several proteins at the same time, offering each of them a separate interface, while in the latter case the hub interacts with its partners one at a time via the same binding site. So far different types of interactions were distinguished based on the properties of the corresponding binding interfaces derived from known three-dimensional structures of protein complexes.\n\nResults: Here we present PiType, an accurate 3D structure-independent computational method for classifying protein interactions into simultaneously possible (SP) and mutually exclusive (ME) as well as into obligate and non-obligate. Our classifier exploits features of the binding partners predicted from amino acid sequence, their functional similarity, and network topology. We find that the constituents of non-obligate complexes

possess a higher degree of structural disorder, more short linear motifs, and lower functional similarity compared to obligate interaction partners while SP and ME interactions are characterized by significant differences in network topology. Each interaction type is associated with a distinct set of biological functions. Moreover, interactions within multi-protein complexes tend to be enriched in one type of interactions.\n\nConclusion: PiType GSK2245840 does not rely on atomic structures and is thus suitable AZD6738 cost for characterizing proteome-wide interaction datasets. It can also be used to identify sub-modules within protein complexes.

“Background: Normally, chronic cerebrospinal venous insufficiency (CCSVI) has been studied using echo-colour Doppler (ECD). Subjects are examined in the supine and sitting positions, in accordance with a static protocol without rotation of the head. A dynamic approach, to assess venous sizes with different degrees of head rotation, has only been performed to improve jugular venous catheterisation. These echographic studies have suggested that head rotation to the contralateral side increases the cross-sectional area (CSA) of the internal jugular veins (IJVs) in supine subjects. Our goal was to evaluate the behaviour of CSA of the IJVs during supine head rotation in multiple sclerosis (MS) patients with CCSVI, compared to healthy controls (HCs).\n\nMethods: The IJVs of 313 MS patients with CCSVI (male 43.8%, male/female 137/176; mean age 45 years old, range 19-77 years) and 298 HCs, matched by gender (male 43.6%, male/female 130/168) and age (mean age 46 years old, range 20-79 years), were compared using ECD.

Results: Twenty-four participants had abnormal glucose testing, including one participant Selleck LOXO-101 (1.5%) who met criteria for diabetes mellitus and 23 participants (34%) who met criteria for impaired fasting glucose/IGT/prediabetes. More patients were identified as having dysglycemia by HbA1c than OGTT. Compared with OGTT, HbA1c had a sensitivity of 60% and a specificity of 69% for diagnosing dysglycemia. Conclusions: In adolescents with PCOS, HbA1c had moderate sensitivity and specificity for detecting dysglycemia compared with OGTT. Clinicians should be aware that both tests have benefits and limitations, and the optimal test for follow-up requires further study.

“Vacuum-puffing has been found to be a very useful process for production of non-deep-fried Yukwa as it ideally produced highly porous and soft texture. In this study, we compared the effects of different green tea powder (GTP) concentrations of 0, 2, 5 and 10 g/100 g on the qualities of vacuum-puffed Yukwa and deep-fried Yukwa. The fat contents of deep-fried Yukwa were significantly higher than vacuum-puffed Yukwa at the same GTP concentrations. Yukwa bases of 10 g/100 g GTP level contained higher total catechins and caffeine contents for vacuum-puffed Yukwa than

find more deep-fried Yukwa. Vacuum-puffed Yukwa had more total phenolics and flavonoids, and a better scavenging effect on DPPH and reducing power than deep-fried Yukwa at the same green tea concentrations. Vacuum-puffing produced more breakable

expanded pellets than deep-frying. The sensory evaluation of Yukwa base showed deep-fried Yukwa added with 2 g/100 g GTP was preferred for all the examined properties. (C) 2013 Elsevier Ltd. All rights reserved.”
“Specific cognitive deficits have been identified in children with epilepsy irrespective of results on intelligence tests. Memory deficits are traditionally attributed to temporal lobe Wnt signaling epilepsy, whereas the impact of frontal lobe epilepsy on memory functions has remained controversial. The aim of this study was the examination of memory abilities in other childhood common epilepsy syndromes (frontal lobe epilepsy (FLE), childhood absence epilepsy (CAE), and benign epilepsy with centrotemporal spikes (BECTS)) and the influence of epilepsy-related variables. Memory was examined in 90 children with epilepsy (each epilepsy group consisted of 30 children), aged 6-15, and compared with 30 control children. Children with FLE showed significant deficits in verbal and visual memory. In addition, type of epilepsy, earlier age at epilepsy onset, and longer active duration of epilepsy were associated with memory problems. Seizure frequency and treatment, however, did not influence memory performance.

To alleviate this limitation, we report two methods-SimIndex (SI) and SimZyme-which use chemical similarity Caspase inhibitor reviewCaspases apoptosis of 2D chemical fingerprints to efficiently navigate large metabolic networks and propose enzymatic connections between the constituent nodes. We also report a Byers-Waterman type

pathway search algorithm for further paring down pertinent networks. Results: Benchmarking tests run with SI show it can reduce the number of nodes visited in searching a putative network by 100-fold with a computational time improvement of up to 10(5)-fold. Subsequent Byers-Waterman search application further reduces the number of nodes searched by up to 100-fold, while SimZyme demonstrates similar to 90% accuracy in matching query substrates with enzymes. Using these modules, we have designed and annotated an alternative to the methylerythritol phosphate pathway to produce isopentenyl pyrophosphate with more favorable thermodynamics than the native pathway. These algorithms will have a significant impact on our ability to use large metabolic networks that lack annotation of promiscuous reactions.”
“Exclusive breast-feeding until 6 months is advised by the WHO as the best practice to feed infants. Yet, some studies have suggested a gap between energy requirements

QNZ manufacturer and the energy provided by human milk for many infants at 6 months. In order to assess the adequacy of WHO recommendations in 6-month-old Senegalese lactating infants, a comprehensive study was designed to measure human milk intake by the dose-to-the mother (H2O)-H-2 turnover method. Infants’

energy intakes were calculated using daily breast milk intake and the energy content of milk was estimated on the basis of creamatocrit. Of the fifty-nine mother-infant pairs enrolled, fifteen infants were exclusively breast-fed (Ex) while forty-four were partially breast-fed (Part). Infants’ breast milk intake was significantly higher in the Ex group (993 (SD 135) g/d, n 15) compared with the Part group (828 (SD 222) g/d, n 44, P = 0.009). Breast milk energy content as well as infants’ growth was comparable in both groups. However, infants’ energy intake from human milk was significantly higher (364 (SD 50) kJ/kg per d (2586 (SD 448) kJ/d)) in the Ex group than in the Part JNK-IN-8 group (289 (SD 66) kJ/kg per d (2150 (SD 552) kJ/d), P<0.01). Compared with WHO recommendations, the results demonstrate that energy intake from breast milk was low in partially breast-fed infants while exclusively breast-fed 6-month-old Senegalese infants received adequate energy from human milk alone, the most complete food for infants. Therefore, advocacy of exclusive breast-feeding until 6 months should be strengthened.”
“We previously described a checkpoint for allelic exclusion that occurs at the pre-B cell to immature B cell transition and is dependent upon the IgH intronic enhancer, E mu.

Each subject was treated with tDCS (20 min., 1 mA) over the left hemisphere in three different conditions: anodic tDCS over Wernicke’s area, anodic tDCS and sham stimulation over Broca’s area. Each experimental condition was performed in five consecutive daily sessions

over three weeks with 6 days of intersession interval.\n\nResults: In all patients, results showed a significantly better response accuracy during the anodic tDCS over Broca’s area with respect to the other two conditions which still selleck screening library persisted at one month after the end of the treatment suggesting a long-term effect on the recovery of their verb retrieval deficits.\n\nConclusion: These findings further confirm that tDCS represents a useful new therapeutic interventions for the rehabilitation of lexical deficits in aphasic patients.”
“Cercidiphyllum japonicum is a rare endemic species of East Asia flora and a common component in riparian forests. Dendrochronological techniques were employed to trace radial growth of C. japonicum in the Shennongjia area of central China and examine its relationships with local climate. Effects of precipitation on width of C. japonicum annual rings were negligible except

for some temporary Selleckchem AZD7762 negative impacts in prior winter. The variables most strongly controlling radial growth were temperatures in the previous December and during the current summer. Relationships for most pairs of ring-width and monthly/seasonal climate variables were temporally unstable but occasionally significant. Radial growth-climate relationships for C. japonicum were likely shaped by riparian site characteristics, root habits, and regional climatic regimes.”
“Background In preclinical studies, davunetide promoted microtubule stability and reduced tau phosphorylation. Because progressive supranuclear palsy (PSP) is linked to tau pathology, davunetide could be a treatment for PSP. We assessed the safety and efficacy of davunetide in patients

with PSP. Methods In a double-blind, parallel CT99021 mw group, phase 2/3 trial, participants were randomly assigned with permuted blocks in a 1:1 ratio to davunetide (30 mg twice daily, intranasally) or placebo for 52 weeks at 48 centres in Australia, Canada, France, Germany, the UK, and the USA. Participants met the modified Neuroprotection and Natural History in Parkinson Plus Syndrome study criteria for PSP. Primary endpoints were the change from baseline in PSP Rating Scale (PSPRS) and Schwab and England Activities of Daily Living (SEADL) scale at up to 52 weeks. All participants and study personnel were masked to treatment assignment. Analysis was by intention to treat. The trial is registered with Clinicaltrials.gov, number NCT01110720. Findings 313 participants were randomly assigned to davunetide (n=157) or to placebo (n=156), and 241 (77%) completed the study (118 and 156 in the davunetide and placebo groups, respectively).
