The construction of mega wind farm projects in the coastal area o

The construction of mega wind farm projects in the coastal area of this SAHA HDAC manufacturer region and the increased traffic in their associated ports is of serious concern. In June 2011, the Scientific Committee of the International Whaling Commission strongly

recommended the urgent development of an environmental impact assessment (EIA) for Isla de Chiloé (IWC 2012). Minimum requirements for an effective EIA include the collection, collation, and analysis of appropriate baseline cetacean data, the development of mitigation measures, and the design of a monitoring program aimed to assess impacts against predetermined conservation objectives and to measure the efficacy of any mitigation measures that are implemented. Research should include collection of baseline information on temporal and spatial aspects of cetacean habitat use, population structure, and behavior, and evaluation of all lethal and nonlethal impacts of human activities in an integrated manner, taking into account the cumulative impacts

from all threats and project developments around the area (IWC, in press). Successful mitigation of vessel strikes requires quantitative estimates of strike number, FK506 in vitro how strike rates change seasonally, where strikes are most likely to occur, and options for minimizing strikes (Vanderlaan et al. 2009). Blue whales (Balaenoptera musculus) should also be included in the EIA because the waters off the northwestern Isla de Chiloé are important feeding habitat for them from late January to early May (Galletti Vernazzani et al. 2012). Our observations highlight the importance of these coastal waters for southern right whales and the need to increase long-term studies, both dedicated and opportunistic, to monitor this critically endangered population. The first interannual resighting of an eastern South Pacific southern right whale and the small number of photo-identified individuals provide additional evidence that this is a small population that deserves its IUCN listing as the “Critically Endangered” Chile-Peru subpopulation (Reilly et al. 2008). The fact that this “subpopulation” is extremely small and several coastal industrial developments may impact it reinforces the

need to implement appropriate management oxyclozanide actions and evaluate their performance as soon as possible. We wish to acknowledge Jaime Conde and Katja Siemund for their valuable contribution with photographs of the recaptured whale; as well as the General Directorate of Maritime Territory and Marine Merchant of the Chilean Navy, Jose Luis Brito from the Natural Science and Archeological Museum of San Antonio and members of the National Marine Mammal Sighting Network for their important collaboration. We would also like to thank Francisco and Miguel Altamirano for their support with the marine survey, Magdalena Altamirano for contributing the videotape showing the reproductive behavior and Roberto Brahm for contributing the video showing the southernmost record of a mother-calf pair.

Moreover, the histological features of PCH could not be completel

Moreover, the histological features of PCH could not be completely distinguished from interface hepatitis because of HCV. Therefore, whether PCH is a real threat to the graft during antiviral therapy is controversial at present. Here, we describe the cases of two patients who developed PCH just after

termination of antiviral therapy for recurrent hepatitis C after living donor liver transplantation (LDLT). As both patients achieved sustained virological response (SVR) and had no history of AIH, the termination of antiviral therapy was the likely trigger for PCH in these patients. A59-YEAR-OLD WOMAN underwent LDLT, with her son as the donor, for HCV-related cirrhosis. Six months after the LDLT, her liver biopsy showed HCV recurrence with mild necroinflammatory activity and mild fibrosis (METAVIR score, A1 F1) without acute cellular rejection (ACR). The HCV genotype BGB324 was 1b and the serum HCV RNA level was 3570 kIU/mL on an Amplicor HCV assay. The serum immunoglobulin (Ig)G level was 1260 mg/dL (reference range, 826–1840) and she was negative for antinuclear antibodies (ANA). She started antiviral therapy with 80 μg/week pegylated interferon-α-2b BVD-523 and 600 mg/day ribavirin, together with 2 mg/day tacrolimus and 1 g/day mycophenolate mofetil (Fig. 1a). HCV RNA was undetectable in serum 2 months after the initiation of the treatment, and antiviral therapy was

continued for 14 months. The immunosuppressants administrated were not changed during and after the antiviral therapy. Before the termination of treatment, her transaminase levels remained normal; however, 1 month later, her aspartate aminotransferase (AST) and alanine aminotransferase

(ALT) levels reached 455 and 650 IU/L, respectively, IgG level increased to 2660 mg/dL, and she was positive for ANA at a titer of 1:40 with a speckled pattern. Type 1 liver–kidney microsomal antibodies (anti-LKM-1) was negative. Liver histology showed moderate necroinflammatory activity and moderate fibrosis (METAVIR score, A2 F2) with plasma cell-rich infiltration (Fig. 1b,c). As serum HCV RNA remained undetectable at that time; the International AIH Group score was 16, indicating definite AIH;[9] and the total DCLK1 score in the histological scoring system for PCH[6] was 11, we diagnosed the patient with PCH. Steroid therapy with methylprednisolone was initiated at a dose of 500 mg/day for 3 days, and then the dose was tapered from 250 mg/day on the fourth day to 62.5 mg/day on the sixth day. Then, the drug was switched to 50 mg prednisolone, which was tapered to 10 mg until the end of the sixth month. AST and ALT levels decreased immediately after the administration of steroid, and normalized during 2 months of the steroid therapy. Liver biopsy after 17 months of steroid therapy showed histological improvement. Serum HCV RNA was undetectable in serum at 24 weeks after the completion of antiviral therapy, and she was considered to have achieved SVR.

2 Glut-2 has been shown to be decreased, suggesting impaired metabolism of carbohydrates. All of this was associated with increased tumor necrosis

factor alpha (TNF-β), decreased hepatic mitochondrial electron transport chain enzyme complex activity, and liver inflammation in the offspring simply from high-fat diet during gestation.2–6 The roles for maternal and child dietary composition, and the potential for novel understanding of the response of nonparenchymal cells and innate immunity in liver, is explored by Mouralidarane et al.7 In their study, offspring of obese click here mice fed a high-fat/high-sugar diet during gestation appeared to be sensitized to a postnatal obesogenic diet because they developed more severe weight gain, hypertriglyceridemia, hepatic inflammation, and fibrosis compared to those exposed either during pregnancy alone or postnatally alone. Interestingly, the dual effect of prenatal and postnatal obesogenic diets appeared to be more than additive in its effect on hepatic fat. Maternal obesity alone did not cause significant weight gain or hepatic fat in the offspring. One issue with the experimental design used by Mouralidarane et al.7 is the inability to assess if the effects are from the gestational weight gain or from the specific macronutrient change. Previous studies have shown fructose and fat have effects on offspring without gestational weight gain.2, 8 Fructose in

the water of pregnant Wistar rats induced SREBP-1c messenger RNA see more (mRNA) and protein expression and fatty acid synthase mRNA expression

in the fetal livers without significant weight gain in the dams.8 While it is difficult to separate effects of weight gain from high-fat and/or high-fructose diets during gestation, this is a potential area of future research that has important implications for public health. Another important distinction is if increased body weight, fat mass, and hepatic fat in the offspring of obese mothers was from increased consumption compared to those without obese mothers. Given the previous work demonstrating increased fat preference by offspring, it would be interesting to know if the feeding behavior was altered by the GBA3 maternal obesity or if the effects were transmitted through decreased tolerance of the postnatal obesogenic diet. Mouralidarane et al. also examined the role of innate immune system dysfunction. They documented increased Kupffer cells numbers, impaired phagocytic function of the Kupffer cells, and increased reactive oxygen species (ROS) production in the mice with pre- and postnatal exposure to the obesogenic diet. Decreased function of Kupffer cells is an important area of interest in the mechanism of NAFLD. Impaired clearance of lipopolysaccharide (LPS) by Kupffer cells could result in accelerated liver injury,9 as seen in the pre- and postnatal-exposed offspring.

7 This is thought to occur mostly through the inhibition of a putative cholesterol transporter, awkwardly named Niemann-Pick C1-like 1 protein (NPC1L1), on the apical membrane of enterocytes. A similar benefit has been demonstrated in NPC1L1 knockout mice on a high-fat and high-cholesterol diet. However, as pointed out by the authors, the relatively trivial increase in fat absorption facilitated by dietary cholesterol is unlikely to explain the excessive weight gain in mice fed both cholesterol and

fat. An alternative explanation suggested by the authors was that, together, a high cholesterol and high-fat diet leads to reductions in energy expenditure. Although this could be due to something as simple as diminished activity level, a more plausible explanation is that the combined diet could actually PR-171 increase energy efficiency. A cause of this improved energy efficiency can be hypothesized based on the newly recognized role Wnt inhibitor of bile acids in energy consumption and thermogenesis. Although bile acids are primarily known for their major roles in bile formation and intestinal fat digestion, recent data indicate that circulating bile acids play an important role in thermogenesis. A newly discovered bile acid activated receptor, TGR5, has been identified in rodent brown adipose

tissue and human muscle that facilitates local thyroid hormone activation, Thiamet G mitochondrial uncoupling, energy “wasting,” and heat generation.8, 9 Thus, factors that change the partitioning of hepatic cholesterol between biliary secretion

versus conversion to bile acids could alter energy efficiency. In the results reported by Savard et al. the high-fat, high-cholesterol diet strongly up-regulated the pathways responsible for decreasing intracellular cholesterol levels through diminished uptake and increased secretion but having no effect on the competing pathway of converting cholesterol to bile acids. Others have shown that LXR activation increases CYP7a1 expression and thus increases conversion of cholesterol to bile acids, so this is somewhat surprising.10 Nonetheless, it is possible that the induction of the LXR pathway by a high-cholesterol diet diminishes circulating bile acids through preferential disposal of cholesterol through other pathways. The impact of this may only be seen when the animals are also fed excessive calories in the form of a high-fat diet. Supporting this hypothesis is the observation that the LXR null mouse is resistant to diet-induced obesity and was shown to have unexplained excessive energy wasting, especially when fed a high-cholesterol diet, an observation made before the role of bile acids in thermoregulation was discovered.

STA-21 treatment had no significant impact on hepatocyte cell cyc

STA-21 treatment had no significant impact on hepatocyte cell cycle progression or cell growth and was not toxic (Supporting Fig. 3); this was also observed for AG490 and S31201 (results not shown). When cells were pretreated with the STAT3 inhibitors followed by JFH-1 infection, we noted a significant decrease in HCV RNA levels by ∼70% at 24 hours (Fig. 3D). For STA-21 treatment selleck chemical this decrease extended to 72 hours postinfection (Supporting Fig. 4). Consistent with this decrease in HCV RNA levels, we observed a marked decrease

in NS5A protein levels with STA-21 treatment (Fig. 3Eii) and demonstrated that STA-21 treatment decreases HCV RNA in a dose-response manner (Fig. 3Ei). This pretreatment scenario could indicate a block of HCV entry; however, as noted above, treatment

with STA-21 this website of replicon cells and Huh-7.5 cells that had an established JFH-1 infection resulted in similar levels of inhibition (Fig. 3B,C), indicating that STAT3 was not acting at the level of HCV entry. Furthermore, pretreatment of Huh-7.5 cells with the STAT3 inhibitors followed by infection with JFH-1, revealed a substantial decrease in specific HCV infectivity (Fig. 4A). However, STAT3 inhibition did not affect the number or size of foci in an established infection, indicating that STAT3 does not play a role in HCV spread (Supporting Fig. 5). Concomitantly, treatment of electroporated JFH-1 Huh-7.5 cells with STA-21 and enumeration of infectious HCV in the culture supernatant revealed a significant reduction in infectious viral titers (Fig. 4B). Taken together, these results show that inhibition of STAT3 leads to significant reduction in HCV RNA and a corresponding decrease in infectious viral titers, suggesting STAT3 plays an important role in the HCV life cycle. STAT3 could be acting to increase HCV replication either indirectly through STAT3-dependent gene expression or through STAT3

interacting with essential host cell factors. An intact MT network is essential for HCV to establish a productive infection[20] and recently activated STAT3 has been shown to play a positive role in regulating MT dynamics, by way of sequestering Thiamine-diphosphate kinase the known tubulin depolymerizer protein STMN1.[21-23] We hypothesized that this ability of STAT3 to positively regulate MT activity could be a potential mechanism by which STAT3 impacts the HCV life cycle. STAT3 /STMN1 interactions have only been demonstrated in T cells[22] and mouse embryonic fibroblasts[23] and therefore we investigated if STAT3 and STMN1 interact in Huh-7.5 cells. Transient expression of STAT3-C and STMN1 in Huh-7.5 cells resulted in colocalization (Fig. 5A) and a physical association, as demonstrated by FRET analysis (Fig. 5B). To investigate if STA-21 disrupts the MT network we investigated the cellular distribution of α-tubulin. In STA-21-treated cells there was significant colocalization between STMN1 and α-tubulin (Fig. 5Cii), which was not observed in the control treated cells (Fig. 5Ci).

For the detection of persisting HCV-NS3 Ag in the liver, liver tissue samples isolated 21 days post-infection were homogenized in RIPA C buffer (50 mM Tris pH 7.5, 1% Triton X-100, 300 mM NaCl, 5 mM ethylenediaminetetraacetic

acid, 0.02% NaN3) to make 2% (w/v) extract and used for immune precipitation/western blot assay. Liver tissue extracts were incubated with protein-G sepharose beads for 30 min at 4°C to remove non-specifically bound proteins. After centrifugation, supernatants were incubated with anti-Flag-M2 antibody Selleckchem C59 wnt (Sigma-Aldrich) coupled protein-G sepharose beads for 2 h at 4°C. After centrifugation, HCV-NS3-3xFlag fusion protein bound to the beads were dissolved in sample buffer and separated on 10% sodium dodecylsulfate polyacrylamide gel electrophoresis gels (Mini PROTEAN TGX gel; Bio-Rad, Hercules, CA, USA) for immunoblot analysis using anti-Flag-M2 antibody and

goat antimouse Ig horseradish peroxidase (KPL, Gaithersburg, MD, USA). Electrochemiluminescence Prime Western Blotting Detection Reagent (GE Healthcare, Little Chalfont, UK) was used for chemiluminescent detection. Mann–Whitney U-tests were used to evaluate the significance of the differences. Correlations between parameters were tested for statistical selleck products significance by Pearson correlation. TO DETERMINE THE effect of the amount of virus dose, we evaluated hepatic inflammation and compared the magnitude of HCV-NS3-specific CD8 T-cell responses and their effector function in the liver of mice infected with 2 × 107, 1 × 109 and 1 × 1010 PFU Ad-HCV-NS3. In histological studies, we observed Ad-infection-mediated hepatic inflammation in mice injected with Anidulafungin (LY303366) 1 × 109 and 1 × 1010 PFU. Especially, infection with 1 × 1010 PFU caused drastic infiltrations

of inflammatory cells (Fig. 1a). We also observed that CD8 lymphocytes infiltrated into the lobular areas of the infected liver in mice injected with 1 × 1010 PFU (Fig. 1b). At 7 days post-infection, we found by flow cytometric assay that the numbers and the frequencies of CD8 T cells in the liver were markedly increased after infection with 1 × 109 PFU and 1 × 1010 PFU, and the increased CD8 T cells decreased with time (Fig. 1c). We did not find significant differences between the number of CD8 T cells of core (+) and core (−) at each time point and infectious dose. In addition, we evaluated core protein expression in the liver in each infectious dose at 7 and 14 days post-infection; there was no significant difference in core protein expression between Ad-infected and non-infected livers (Fig. 1e). Using major histocompatibility complex (MHC) class I tetramer complexed with the H2-Db-binding HCV-NS3 GAVQNEVTL epitope, we found that i.v. infection with 2 × 107 PFU generally elicited only a weak expansion of HCV-NS3 tet+ CD8+ IHL (Fig. 2a,b) and IFN-γ+ HCV-NS3 tet+ CD8+ IHL (Fig. 2a,c).

6,7,40 In this study, about a third of the families (22) contributed to

Enzalutamide the LOD score on Xp22. Twelve were MO families, 8 were MA families, and 2 families were diagnosed with FHM. Interestingly, 12 out of these 22 families were of the “mixed” type, with more than one migraine phenotype present in the family, and in both FHM pedigrees all 3 phenotypes of migraine were present (see Fig. 3). The phenotypic variability at what is apparently one genetic locus further supports the notion of a common genetic (and thus pathophysiologic) origin for the different clinical types of migraine. In summary, by screening the X-chromosome we identified a locus for migraine susceptibility on Xp22 in a subset of a large sample of migraine families of European decent. Families with different clinical types of migraine (MO, MA, FHM) contributed to this single locus. We anticipate that candidate Vismodegib supplier gene screening may yield novel insights into the pathophysiology of this common and disabling disorder. (a)  Conception and

“Objectives.— The goal of this study was to use protein array analysis to investigate temporal regulation of stimulated cytokine expression in trigeminal ganglia and the spinal trigeminal nucleus in response to co-treatment of sumatriptan and naproxen sodium or individual drug. Background.— Activation of neurons and glia in trigeminal ganglia and the spinal trigeminal nucleus leads to increased levels of cytokines

that promote peripheral and central sensitization, which are key events in migraine pathology. While recent clinical studies have provided evidence that a combination of sumatriptan and naproxen sodium is more efficacious in treating migraine than either drug alone, it is not well understood why the combination therapy is superior to monotherapy. Methods.— Male Endonuclease Sprague–Dawley rats were left untreated (control), injected with capsaicin, or pretreated with sumatriptan/naproxen, sumatriptan, or naproxen for 1 hour prior to capsaicin. Trigeminal ganglia and the spinal trigeminal nucleus were isolated 2 and 24 hours after capsaicin or drug treatment, and levels of 90 proteins were determined using a RayBio® Label-Based Rat Antibody Array (RayBiotech, Norcross, GA, USA). Results.— Capsaicin stimulated a >3-fold increase in expression of the majority of cytokines in trigeminal ganglia at 2 hours that was sustained at 24 hours.

Although some of these influences are well documented (ie ABO b

Although some of these influences are well documented (i.e. ABO blood group), others have either only very recently been detected or remain to be characterized. A personal history of excessive mucocutaneous bleeding is a key component in the diagnosis of a number Gefitinib mw of mild bleeding disorders,

including VWD, platelet function disorders and coagulation factor deficiencies. However, the evaluation of haemorrhagic symptoms is a well recognized challenge for both patients and physicians, because the reporting and interpretation of bleeding symptoms is subjective. As a result, bleeding assessment tools (BATs) have been developed and studied in a variety of clinical settings [34, 52, 53]. These tools are invaluable in the identification of symptomatic patients; symptomatic XL765 manufacturer VWD has a prevalence of ∼1 in 1000; however, a review of diagnosed cases reveals that far fewer patients have been diagnosed, and therefore, far fewer have access to appropriate treatment. The work in BATs has been pioneered by a group of Italian researchers, and the resultant ‘Vicenza Bleeding Questionnaire’ stands as the original BAT. Over the years various modifications of the Vicenza Bleeding Questionnaire have taken place (Fig. 6), and validation studies have been published. The Condensed MDMCM–1 VWD Bleeding Questionnaire is the one developed and validated by the group

at Queen’s University, Kingston, Ontario, Canada [53]. It is a summative standardized scoring system, which was condensed from the MCMDM–1VWD version by removing all questions that do not directly affect the bleeding score. It has been validated prospectively as a screening tool for VWD with a sensitivity of 100%, specificity of 87%, positive predictive value of 0.20 and negative predictive

value of 1.0. A subsequent, paediatric-specific version has also been developed and validated, although given the lack of haemostatic challenges in children, it is less sensitive compared with adults [54]. The ISTH–BAT was published in 2010 [55], Sitaxentan which builds on the knowledge of the previous Vicenza-based BATs with some important modifications; it captures the frequency of bleeding episodes in contrast to the previous version, which saturates if used in more severe bleeding disorders. A web-based version is available through Rockefeller University [56]. Overall, BATs can distinguish between normal and persons with a bleeding disorder, identify those at risk of having a bleeding disorder, those who are very unlikely to have a bleeding disorder and describe disease severity within a limited spectrum. BATs are limited in the setting of menorrhagia, because no assessment of quality of life is included, and heavy menstrual bleeding has such a negative affect on quality of life.

Conversely, silencing endogenous FoxC1 expression markedly reduce

Conversely, silencing endogenous FoxC1 expression markedly reduced cell migration and invasion in HCCLM3 cells (high initial metastatic potential) Selleckchem VX-809 (Fig. 1D). To further explore the role of FoxC1 in tumor metastasis in vivo, cells were transplanted into livers of nude mice. Representative bioluminescent imaging (BLI) of the different groups is shown in Fig. 1E1. Histological

analysis (Fig. 1E5) further confirmed that the incidence of lung metastasis in the SMMC7721-FoxC1 group was significantly increased, compared to that in the control group (60% versus 10%). In the HCCLM3-shcontrol group, all of the mice developed lung metastases; however, only 5 mice in the HCCLM3-shFoxC1 group developed lung metastases (100% versus 50%; Fig. 1E1,E2). The number of lung metastatic nodules in the SMMC7721-FoxC1 group was

increased, compared to that in the SMMC7721-control group; however, the number of lung metastatic nodules in the HCCLM3-shFoxC1 group was significantly reduced, compared to that in the HCCLM3-shcontrol group (Fig. 1E3). Furthermore, the SMMC7721-FoxC1 group had a shorter OS time than the SMMC7721-control group, whereas the HCCLM3-shFoxC1 Smad inhibitor group had a longer OS time than the HCCLM3-shcontrol group (Fig. 1E4). These data suggested that FoxC1 promoted HCC invasion and metastasis. EMT plays a critical role in metastasis. Specifically, EMT induces tumor-associated epithelial Tau-protein kinase cells to obtain mesenchymal features, which results in reduced cell-cell

contact and increased motility.22 Up-regulation of FoxC1 in SMMC7721 cells resulted in the decreased expression of epithelial markers (E-cadherin and ß-catenin) and increased expression of mesenchymal markers (vimentin and fibronectin), as evidenced by immunofluorescence (IF), western blotting analysis, and real-time PCR. After FoxC1 knockdown in HCCLM3 cells, expression of epithelial markers was significantly increased and expression of mesenchymal markers was markedly decreased (Fig. 2A-C). These findings suggested that FoxC1 induced EMT in HCC cells. Functional loss of E-cadherin is considered a hallmark of EMT.23 A major mechanism of E-cadherin down-regulation is its direct transcriptional repression by repressors, including Snai1, Twist, Slug, Zeb1, and SIP1.24 We determined whether FoxC1 inhibited E-cadherin expression by regulating the expression of these repressors. Real-time PCR analysis showed that FoxC1 markedly increased Snai1 expression, but had no significant effect on mRNA levels of Twist, Slug, Zeb1, or SIP1 (Fig. 3A1). Furthermore, FoxC1 up-regulated Snai1 expression and decreased E-cadherin expression in SMMC7721 cells, whereas the inhibition of Snai1 expression using the lentivirus, LV-shSnai1, significantly attenuated the loss of E-cadherin expression induced by FoxC1.

Habituation in migraineurs has been extensively studied with visu

Habituation in migraineurs has been extensively studied with visual evoked potentials. Despite discrepant results, possibly related to the use of different stimulus conditions, lack of habituation in the period between attacks is presently considered to be a neurophysiological hallmark of migraine. Midoccipital

monocular visual evoked potentials were recorded and analyzed in 27 interictal migraineurs and 34 healthy controls using a blinded study design. Small 8′ checks and large 65′ checks were applied in random order, both with 3 reversals per second. Six consecutive blocks of 100 responses were recorded for each check size. N70-P100 and P100-N145 peak-to-peak amplitudes were measured. Regression slopes across the 6 blocks, supplemented by last block/first block ratio and repeated measures analysis of variance with amplitude as the dependent variable, were used to test for habituation. N70-P100 selleckchem habituation to small and large checks

was observed in controls (mean slope −0.30 and −0.11 μV/block) and interictal migraineurs (−0.32 and −0.26 μV/block). P100-N145 habituation to small checks in controls (mean slope −0.39 μV/block) and to small and large checks in interictal migraineurs (−0.38 and −0.17 μV/block) was also observed. None of the habituation check details measures were significantly different between healthy controls and migraineurs (F < 1.6, P > .18). The check-size effect was similar in the 2 groups (F < 2.3, P > .14). Reversal rate and check-size differences do not seem to explain the discrepant visual evoked potential habituation results ADP ribosylation factor in the migraine literature. Furthermore, no differences in first block amplitudes or N70, P100, and N145 latencies between healthy controls and migraineurs were found. We recommend blinded evaluation designs in future habituation studies in migraine. “
“Migraine has been linked with an increased risk

of stroke and an increased prevalence of clinically silent brain lesions and white-matter hyperintensities. As it is known that stroke and structural brain lesions are associated with an increased risk of cognitive decline, it has been hypothesized that migraine may be a progressive brain disorder and associated with an increased risk of cognitive impairment. Given the prevalence of migraine in the population, especially among women, and the aging of the population, an association between migraine and cognitive impairment would have substantial public health implications. In this review, we will summarize the existing evidence evaluating the association between migraine and cognitive function. Additionally, we will discuss methodological issues in migraine and cognitive function assessment and elaborate on study design strategies to address this important question.
