Is cytokine response lower after lung volume reduction through bilateral thoracoscopy versus sternotomy?
Lung volume reduction surgery performed through bilateral video-assisted thoracoscopy (BVATS) was associated in the National Emphysema Treatment Trial with a statistically significant reduction in intensive care unit days, failure to wean, hospital stay, and cost, and earlier recovery . Serum cytokine levels were measured by radioimmunoassay in 9 consecutive, steroid-free patients undergoing sternotomy and lung volume reduction . Proinflammatory interleukin 6 and interleokin 8 and antiinflammatory anti-inflammatory antileukins 10 were evaluated preoperatively and postoperatively .
Use of a BVATS approach to lung volume reduction surgery is associated with reduced postoperative release of proinflammatory cytokines compared with a sternotomy approach. This may account for the reduction in recovery time and some measures of postoperative morbidity seen with the BVATS approach.
yes

Do proteomics analyses of subcutaneous adipocytes reveal novel abnormalities in human insulin resistance?
Proteins of isolated adipocytes were quantified by mass spectrometry using normalized spectral abundance factors . Of 1,245 proteins assigned, 30 were detected in at least 12 of the 23 subjects that differed significantly in abundance between IR and IS . IR displayed a pattern of increased cytoskeletal proteins and decreased mitochondrial proteins . In subgroup analyses of adiposity-matched subjects, several of these changes were less pronounced in IR, but the abundance of proteins related to lipid metabolism and the unfolded/misfolded protein response were significantly and unfavorably altered .
These results confirm lower abundance of mitochondrial proteins and suggest increased cytoskeletal proteins and decreased FABP4 and FABP5 in subcutaneous adipocytes of typical IR individuals. Changes in proteins related to lipid metabolism and the unfolded/misfolded protein may discriminate IR and IS individuals of equal adiposity.
yes

Is cardiovascular fitness associated with altered cortical glucose metabolism during working memory in ɛ4 carriers?
The possibility that ɛ4 may modulate the effects of fitness in the brain remains controversial . The present exploratory FDG-PET study aimed to better understand the relationship among ɚ4, fitness, and cerebral metabolism in 18 healthy aged women (nine carriers, nine noncarriers) during working memory . High fit ə�4 carriers had greater glucose uptake in the temporal lobe than the low fit ˚4 carriers, but low fit carriers have greater uptake in frontal and parietal lobes .
We demonstrate that fitness differentially affects cerebral metabolism in ɛ4 carriers only, consistent with previous findings that the effects of fitness may be more pronounced in populations genetically at risk for cognitive decline.

Are proinsulin levels in patients with pancreatic diabetes associated with functional changes in insulin secretion rather than pancreatic beta-cell area?
Hyperproinsulinaemia has been reported in patients with type 2 diabetes . It is unclear whether this is due to an intrinsic defect in β-cell function or secondary to the increased demand on the β-cells . We investigated whether hyperproinsulin is also present in patients who have secondary diabetes . Intact and total proinsulin levels were compared with the pancreatic β- cell area and measures of insulin secretion and action . There was a weak inverse association between the total pro-insulin/insulin ratio and pancreatic .

Is bax required for resection-induced changes in apoptosis , proliferation , and members of the extrinsic cell death pathways?
After 50% jejunoileal resections or transections, adaptation was analyzed in duodenal-jejunal and ileal segments from C57BL/6 Bax(+/+) and Bax(-/-) mice . By 1-week postresection, villus heights and crypt depths were increased in both genotypes . In Bax.(+) mice, adaptation occurred in concert with increased crypt proliferative and apoptotic indices . Enterocyte migration increased in Bax.-(+%) mice, but Bax (-%) mice did not show increases in proliferation or apoptosis .
Postresection adaptation involves parallel changes in crypt proliferation and apoptosis, but, as observed in Bax(-/-) mice, it can occur without increased proliferation. These studies demonstrate that spontaneous gut apoptosis is Bax independent, whereas adaptation-related apoptosis is Bax-dependent. Differences between resected Bax(+/+) and Bax(-/-) mice suggest that apoptosis in the adapting gut utilizes the extrinsic pathway, but this requires linkage to the mitochondrial pathway via Bax. The increased adaptive response in Bax(-/-) mice indicates that modulation of apoptosis may be useful for enhancing adaptation.

Is saline PCO2 an important source of error in the assessment of gastric intramucosal pH?
A comparison of four blood gas analyzers (ABL-520, Ciba Corning, IL-1302, and Nova) used tonometered saline as the reference . The bias of the PCO2 measurement increased (p < .001) at the higher PCO 2 levels . The type of analyzer also influenced the bias (p) of the bias . The use of the buffer reduced the bias of all analyzers . A difference in gastric intramucosal pH of 0.06 pH units can be reliably detected at a PCOO2 of 45 torr (6 kPa) by all analyzer .
Measurement of saline PCO2 is an important source of error in the assessment of gastric intramucosal pH, and the error depends on both the analyzer used and the actual PCO2 level. Direct comparison of pH values obtained by different analyzers is not valid.

Do herpes viruses and HIV-1 drug resistance mutations influence the virologic and immunologic milieu of the male genital tract?
Study looked at semen and blood samples collected from 115 recently HIV-1 infected antiretroviral naive men who have sex with men . Seminal herpes virus shedding was observed in 75.7% of individuals . CMV and EBV seminal shedding was associated with higher number of seminal T-lymphocytes, but only presence of seminal CMV DNA was linked to increased immune activation of T-lysmphocytes in semen . Study was conducted to further understand the role that chronic viral infections of the male genital tract play on HIV- 1 dynamics and replication .
Despite high median CD4 T-cells numbers, we found a high frequency of herpes viruses seminal shedding in our cohort. Shedding of CMV, EBV and HHV-8 and absence of DRM were associated with increased frequency of HIV-1 shedding and/or higher levels of HIV-1 RNA in semen, which are likely important cofactors for HIV-1 transmission.

Are fragile histidine triad gene alterations essential for hepatocellular carcinoma development in South Korea?
Aberrant FHIT transcripts were detected in 11 of 48 surrounding non-tumor liver tissues and 27 of 48 HCC samples (22.9% vs 56.3%) No point mutations were identified within the open reading frame region of FHit . Loss of heterozygosity (LOH) was detected in 4 of 42 informative cases for D3S1300, and 3 of 29 informative cases . Reduced expression of protein (Fhit) was observed in 8 (16.7%) of 48 samples, with complete loss of Fhit in only 1 case .
Aberrant FHIT transcripts were more common in HCC tissues as compared to non-cancerous liver tissues. However, Fhit expression was lost or reduced in a minor fraction of HCC tissues, while it was strongly expressed in non-cancerous liver tissues. Therefore, our study suggests that FHIT plays a role in relatively few HCC cases in South Korea.

Does glycogen synthase kinase-3 overexpression replicate electroretinogram anomalies of offspring at high genetic risk for schizophrenia and bipolar disorder?
Electroretinogram anomalies occur in patients with psychiatric disorders and represent potential biomarkers for diagnosis . Several genetic variants associated with enhanced risk for SZ and/or BD can activate glycogen synthase kinase-3 isozymes (GSK3α and β) Here we examined the potential contribution of GSK3β(+/-) in the modulation of the ERG . An increase in cone a- and b-wave amplitude at Vmax and in rod b-waves was observed in mice having increased (prp GSK3β mice) or reduced (GSk3β) mice .
GSK3 expression modulates some ERG parameters. The phenotype observed in prpGSK3β mice is consistent with observations made in HRs. ERG anomalies observed in GSK3β(+/-) and GSK3α-KO mice confirm an association between the rod and cone b-wave amplitude and the expression of GSK3 isozymes. Changes in GSK3 expression or activity may explain some ERG anomalies in HRs and patients, thus supporting the biological validity of ERG measurements as a valuable biomarker for psychiatric research.

Is serotonin transporter polymorphism associated with increased apnea-hypopnea index in older adults?
A functional polymorphism of the serotonin transporter gene (5-HTTLPR) has previously been related to upper airway pathology, but its contribution to obstructive sleep apnea (OSA) remains unclear . We aimed to investigate the relationship between apnea-hypopnea index (AHI) and genetic variations in the promoter region of the 5-HTTPR in older adults . DNA samples from 94 community-dwelling older adults (57% female, mean age 72 ± 8) were genotyped for the 5HTLPR polymorphism . A single allele change from s to l resulted in an increase of AHI by 4.46 per hour of sleep .
The observed significant association between the 5-HTTLPR l allele and severity of OSA in older adults suggests that the l allele may be important to consider when assessing for OSA in this age group. This association may also explain some of the observed variability among serotonergic pharmacological treatment studies for OSA, and 5-HTT genotype status may have to be taken into account in future therapeutic trials involving serotonergic agents.

Is reduced diversity of the intestinal microbiota during infancy associated with increased risk of allergic disease at school age?
Changes in the human microbiome have been suggested as a risk factor for a number of lifestyle-related disorders, such as atopic diseases, possibly through a modifying influence on immune maturation in infancy . We found that bacterial diversity in the early intestinal flora 1 and 12 months after birth was inversely associated with the risk of allergic sensitization, allergic rhinitis, peripheral blood eosinophil counts, asthma, and atopic dermatitis . There was no association with the development of asthma or atopic skin prick tests .
Reduced bacterial diversity of the infant's intestinal flora was associated with increased risk of allergic sensitization, allergic rhinitis, and peripheral blood eosinophilia, but not asthma or atopic dermatitis, in the first 6 years of life. These results support the general hypothesis that an imbalance in the intestinal microbiome is influencing the development of lifestyle-related disorders, such as allergic disease.

Is a complex additive model of inheritance for Hirschsprung disease supported by both RET mutations and predisposing RET haplotypes?
The RET proto-oncogene is considered to be the major susceptibility gene involved in Hirschsprung disease . Traditional RET germline mutations account for a small subset of HirschSprung disease patients . There is a specific haplotype of RET associated with the sporadic forms of the disease . We have screened the coding region of RET in 106 Spanish Hirsch Sprung patients using dHPLC technology . A significant over-transmission of the "Hirschsprunk disease haplotype" was detected when comparing transmitted versus nontransmitted alleles in the group of Hilssprung Disease triads without mutation .
These results would be concordant with a complex additive model of inheritance. The whole findings seem to suggest that low-penetrance mutations would be necessary but not sufficient and the additional presence of the "Hirschsprung disease haplotype" could contribute to the manifestation of the disease.

Is perifoveal vitreous detachment the primary pathogenic event in idiopathic macular hole formation?
26 eyes of 26 consecutive patients with stage 1 or stage 2 idiopathic macular hole underwent complete ophthalmologic examination, contact lens biomicroscopy, and B-scan ultrasonography or vitreoretinal surgery . In eyes that were operated on, the posterior cortical vitreous layer was meticulously examined with a silicone-tipped cannula . In 25 (96%) of 26 eyes, one or more examination techniques revealed a shallow, localized detachment of the perifoveal vitreously . In 12 (92%) of 13 eyes with a stage 2 hole but no operculum .
These findings suggest that localized perifoveal vitreous detachment (an early stage of age-related posterior vitreous detachment) is the primary pathogenic event in idiopathic macular hole formation. We postulate that detachment of the posterior hyaloid from the pericentral retina leads to foveal dehiscence by exerting anterior traction on the foveola and by localizing into the foveola the dynamic vitreous traction associated with ocular rotations.

Do contraceptive policies affect post-abortion provision of long-acting reversible contraception?
Placement of long-acting reversible contraceptives (LARC) directly after an abortion provides immediate contraceptive protection and has been proven safe . Most patients were provided with contraception; 6.6% chose LARC methods offering the highest level of protection . State policies had a significant impact on how women paid for contraception and the likelihood of LARC use . Patient use was higher in states with contraceptive coverage mandates or Medicaid family planning expansion programs (p ≤.01) or Medicaid expansion programs . LARC was lower in stand-alone abortion clinics, but higher with recent clinician training and in the absence of clinic flow barriers .
Use of the most effective contraceptives immediately post-abortion is rare in the United States. State policies, high cost to patients, and the ongoing need for clinician training in the methods hinder provision and patient uptake. Contraceptive policies are an important component of abortion patient access to the most effective methods.

Is p-glycoprotein more efficient at limiting uptake than inducing efflux of colchicine and vinblastine in HL-60 cells?
Uptake and efflux kinetics were studied in vitro in human lymphocytes and in HL-60 cells with or without the P-GP modulator, verapamil . In HL-50 cells, colchicine uptake was non-linear and slower than that of vinblastine . Verapamamil did not significantly modify colchichine uptake half-life, but increased its intracellular accumulation by 23% and that of . vinblasine by 81% .
P-gp may not be the main reason for the slowness of colchicine uptake. It may be more efficient at controlling entry of colchicine and vinblastine through the plasma membrane than at mediating their efflux from HL-60 cells.

Does inhibition of MKP-1 expression potentiate JNK related apoptosis in renal cancer cells?
Anisomycin (JNK activator) and Ro-318220 (MKP-1 expression inhibitor) were analyzed by alamar blue assay . Cells treated with anisomyin resulted in a transient activation of JNK without inducing apoptosis . When cells were treated with Ro-317220, MKP1 expression decreased in Caki-1 and KU 20-01 cells but not in ACHN or 769P cells . Combined treatment of Caki1 and . KU .20-01 . cells with an .isomyc and Ro.318220 resulted in . a decrease in MKP . expression concomitant with persistent JNK activation .
These results suggest that prevalent MKP-1 expression in RCC contributes to cancer cell survival by attenuating an apoptosis inducing signal cascade via JNK. Since Ro-318220 potentiated JNK related apoptosis, JNK activation by blocking MKP-1 expression may be an effective therapeutic approach to RCC.

Aortic valve-sparing surgery (with regards to the age of the patient) was studied in 139 patients after aortic . valve surgery . The younger patients scored significantly better in 4 of 4 physical subscales and in 2 of 4 mental subscales than the older patients . In the valve-specific questionnaire, all 3 groups free of anticoagulation (Y, O, and R) displayed greater freedom from negative valve-related concerns. In SF-36, the younger patients and the Ross patients scored better in .
Postoperative quality of life is influenced by the type of aortic valve procedure and is negatively linked with mechanical prosthesis implantation and long-term anticoagulation. Aortic valve-sparing strategy should be considered in cases with suitable valve morphology due to favorable clinical results and beneficial impact on the long-term quality of life.

Does a polymorphism in the P2X7 gene increase susceptibility to extrapulmonary tuberculosis?
Activation of P2X(7) receptor on human macrophages induces killing of mycobacteria . We have identified polymorphisms in the P2 X(7 gene that markedly reduce this killing . The 1513A-C polymorphism was present in Southeast Asians and the allele was associated with reduced killing of Mycobacterium tuberculosis . ATP-mediated killing of macrophage was ablated in subjects homozygous for the 1513C allele and significantly impaired in subjects from heterozygous subjects . There was a strong correlation between the degree of my cobacterial killing and ATP-induced apoptosis .
The 1513C allele increases susceptibility to extrapulmonary TB, and this defect is associated with the reduction in the capacity of macrophages to kill M. tuberculosis.

Is a consensus surface activation marker signature partially dependent on human immunodeficiency virus type 1 Nef expression within productively infected macrophages?
HIV-infected macrophages were significantly enriched in the CD14+ fraction (3 to 5-fold, p = .0001) compared to bystander, or uninfected cells in the same culture . However, the enrichment and higher levels of CD14 on HIV expressing macrophage macrophags did not depend on the production of HIV Nef . Sixty to eighty percent of macrophaged cells productively infected with HIV after day 28 post-infection were also enriched in cells expressing the activation markers CD69 (2 to 4-fold) and CD86 .
These findings suggest that HIV actively regulates the expression of a subset of surface molecules involved in innate and inflammatory immune signaling in primary human macrophages through Nef-dependent and Nef-independent mechanisms acting within productively infected cells.

Are pulmonary exacerbations associated with subsequent FEV1 decline in both adults and children with cystic fibrosis?
Study of subjects followed in the Cystic Fibrosis Foundation Patient Registry from 2003 through 2006 . Children with one or more exacerbations experienced a significantly (P < 0.001) greater rate of FEV(1) decline in 2004-2006 . Only those with 3+ exacerbations in 2003 had a significantly greater rate . rate of decline in forced expiratory volume in 1 sec (FEV) decline among adults, compared to those with no exacerbations .
There is a strong association between the frequency of pulmonary exacerbations and subsequent decline in pulmonary function. In adults, having 3+ exacerbations, and among children, having any exacerbations is associated with a greater rate of decline in the ensuing 3 years. Improved prevention, identification, and treatment of pulmonary exacerbations are likely to have long-term benefits for patients with CF, especially children.

Is urinary deoxynivalenol correlated with cereal intake in individuals from the United kingdom?
Deoxynivalenol (DON) is a toxic fungal metabolite that frequently contaminates cereal crops . Don is toxic to animals, but the effects on humans are poorly understood, in part because exposure estimates are of limited precision . Don was detected in 296 of 300 (98.7%) urine samples . Cereal intake was significantly associated with urinary DON (p < 0.0005), with the geometric mean urinary levels being 6.55 microg DON/day [95% confidence interval (CI), 5.71-7.53]
The majority of adults in the United Kingdom appear to be exposed to DON, and on the basis of the urinary levels, we estimate that some individuals may exceed the European Union (EU) recommended maximum tolerable daily intake of 1,000 ng DON/kg (bw). This exposure biomarker will be a valuable tool for biomonitoring as part of surveillance strategies and in etiologic studies of DON and human disease risk.

Do syngeneic immune-dependent abortions in mice suggest paternal alloantigen-independent mechanisms?
Sib-crosses of C57Bl/6J mice resulted in selective mid-gestational abortion of 88% of the tbp(deltaN/delta N) fetuses . In dams lacking mature lymphocytes (rag1-/-), nearly all tbpN/DeltaN) fetus survived to birth, indicating abortions were immune-dependent . Neither hemizygous paternal allogeneic loci nor homozygous loci, including a haplotype-mismatched major histocompatibility complex (MHC), increased abortion frequencies .
Results suggested that mechanisms for maternal tolerance of paternal alloantigens, including mismatched MHC antigens, were intact in these pregnancies, yet maternal immune-dependent paternal antigen-independent abortion of mutants occurred. These data indicate that, in some cases of immune-mediated abortions, the presence of paternal alloantigens can be coincidental and superfluous to the compromising rejection response.

Do scores on the Safe Functional Motion test predict incident vertebral compression fracture?
The Safe Functional Motion test (SFM) document movement strategies that may increase the risk of osteoporotic fracture . We hypothesize that scores on the SFM are associated with incident VCF . After adjusting for variables known to predict vertebral compression fracture, baseline score on SFM was a significant independent predictor of incident V CF at 1- and 3-year follow-ups . We also hypothesized that gender and prevalent VCF were also significant predictors at follow-up visits .
For every 10-point increase in SFM score, the odds of future VCF decreases by 18 % at 1 year and 27 % at 3 years after adjusting for known covariates. The SFM may aid in the identification of modifiable functional risk factors for VCF.

Do component reductions in oxygen delivery generate variable haemodynamic and stress hormone responses?
We hypothesized that an equivalent decrease in DO2 after reductions in each separate component of the equation would result in different haemodynamic, tissue oxygenation, and stress hormonal responses . We found that haemorrhage generated the largest decrease in cardiac output, and the greatest stress hormone response . In contrast, rapid hypoxaemia produced a minor impact on global haemodynamics yet induced the greatest decrease in regional oxygenation . A greater degree of hyperlactataemia was observed with graded insults compared with those administered rapidly .
Decreasing global oxygen delivery, achieved by targeted reductions in its separate components, induces varying circulatory, tissue oxygen tension, and stress hormone responses. We conclude that not all oxygen delivery is the same; this disparity should be emphasized in classical teaching and re-evaluated in patient management.

Does simulated ischemia protect against efferent sympathetic denervation following acute myocardial infarction in canine hearts?
Preconditioning the myocardium with brief episodes of ischemia preserves efferent autonomic responsiveness of noninfarcted mycardium apical to a site of acute transmural ischemias by mechanism(s) still unknown . We hypothesized that repeated brief exposure of the my cardiium to simulated ischemic milieu including hypoxia, low pH, and adenosine would be as effective as brief coronary occlusions in creating this protection . We analyzed the effects on the time course and extent of efferent sympathetic denervation during a subsequent 3-hour sustained ischemiia in three groups of dogs .
Thus, brief exposure of the left ventricular myocardium to ischemic metabolites prior to a subsequent permanent coronary occlusion does not trigger mechanism(s) that are responsible for protection against efferent sympathetic denervation apical to an area of transmural myocardial infarction/ischemia.

Is treatment with beta-blockers associated with lower levels of Lp-PLA2 and suPAR in carotid plaques?
To determine whether a long-term treatment with beta-blockers influences the inflammatory activity in carotid artery disease by reducing the carotodid plaque levels of lipoprotein-associated phospholipase A2 (Lp-PLA2), its enzymatic products lysophosphatidylcholine (lysoPCs) and of soluble urokinase plasminogen activator receptor (suPAR) Levels of Lp- PLA2 and suPAR were positively correlated (r=.637, P<.0001) with the three lysoPC species tested .
The reduced levels of Lp-PLA2 and suPAR in human carotid plaques of subjects on long-term treatment with beta-blockers suggest their possible protective role in plaque inflammation. Our findings support an even more selective Lp-PLA2 and suPAR inhibition as a possible strategy for the prevention of cardiovascular disease.

Is postoperative pressure regulation in glaucoma shunt surgery : focal tube constriction the answer?
A silicone tube identical to the one used in the Baerveldt and other glaucoma drainage implants was connected to a syringe-pump delivering a continuous flow of demineralized water at a rate of 2.5 microliters per minute . Focal constriction of the tube was obtained by a ring made of a shape-memory metal alloy designed for this purpose . In a second experiment the tube lumen was constricted by placing the tube between the jaws of a micrometer .
It is not possible to regulate pressure in a reliable and predictable way merely by constricting the tube lumen of glaucoma drainage implants.

Does single histidine-substituted cardiac troponin I confer protection from age-related systolic and diastolic dysfunction?
Myocardial ischaemia is a significant cause of morbidity and mortality in the elderly . We hypothesized troponin I-mediated augmentation of myofilament calcium sensitivity would protect cardiac function in aged mice . We found that Tg hearts showed significantly improved systolic function at 4 months, which was sustained for 2 years . Age-related diastolic dysfunction was also attenuated in Tg mice as assessed by Doppler measurements of the mitral valve inflow and lateral annulus Dopplers .
This study shows that increasing myofilament function by means of a pH-responsive histidine button engineered into cTnI results in enhanced baseline heart function in Tg mice over their lifetime, and during acute hypoxia improves survival in aged mice by maintaining cardiac contractility.
yes

Are fragile X full mutation expansions inhibited by one or more AGG interruptions in premutation carriers?
Fragile X CGG repeat alleles often contain one or more AGG interruptions that influence allele stability and risk of a full mutation transmission from parent to child . We have examined transmissions of maternal and paternal alleles with 45-90 repeats to quantify the effect of AGG interrupts on fragile X repeat instability . For maternal alleles <75 repeats, 89% (24/27) that expanded to full mutation had no AGGs . Two contractions in maternal transmission were accompanied by loss of Aggs, suggesting a mechanism .
These results strengthen the association of AGG repeats with CGG repeat stability and provide more accurate risk estimates of full mutation expansions for women with 45-90 repeat alleles.
