Effects of Armolipid Plus on small dense LDL particles in a sample of patients affected by familial combined hyperlipidemia

Abstract Aim: The aim of this study was to test small dense LDL changes with Armolipid Plus treatment in patients with familial combined hyperlipidemia (FCHL). Methods: After 4 weeks, 30 patients with FCHL were included in an 8-week, randomized, double-blind study and were taking, in addition to the standard diet, either placebo or Armolipid Plus. Results: The placebo group showed no statistically significant differences in the studied parameters; instead, in the Armolipid Plus group, statistically significant reduction differences were detected in BMI (p = 0.010), LDL score (p = 0.035) and an increase in mean LDL particle diameter (p = 0.040). Conclusion: The combination of a standard diet with Armolipid Plus is able to reduce LDL score and increase LDL particle diameter in a group of FCHL after 8 weeks of treatment.
Outcome of protein-losing gastroenteropathy in systemic lupus erythematosus treated with prednisolone and azathioprine.

OBJECTIVES To report the efficacy of prednisolone and azathioprine (AZA) in the treatment of systemic lupus erythematosus (SLE)-related protein-losing gastroenteropathy (PLGE). METHODS Between 1995 and 2002, 16 consecutive patients with SLE-related PLGE were treated with a regimen consisting of high-dose prednisolone (0.8-1 mg/kg/day for 6 weeks, then tapered to < or =10 mg/day) and AZA (2 mg/kg/day). Protein leakage from the gastrointestinal tract was confirmed by 99mTc-labelled human serum albumin scintigraphy and significant urinary loss of protein was excluded. Clinical response at 6 months of therapy was assessed and patients were followed for relapse of PLGE. RESULTS Clinical characteristics of our patients at the time of PLGE were: age 36.2 +/- 8.7 (s.d.) yr; female:male ratio 15 : 1; mean SLE duration 29.6 +/- 65 months. Twelve patients had PLGE as the initial presentation of SLE. Fifteen (94%) patients had concomitant activity in other organs. All patients presented with oedema and eight patients (50%) had non-bloody diarrhoea. The mean serum albumin level was 22.8 +/- 5.7 g/dl. Protein leakage was at the small bowel in 11 (69%) patients and the large bowel in 5 (31%) patients. At 6 months of therapy, 14 (88%) patients had complete clinical response, 1 (6%) patient responded partially and 1 patient (6%) was treatment-refractory. Patients who responded were maintained on low-dose prednisolone (7.8 +/- 6.1 mg/day) and AZA (56.3 +/- 37 mg/day). Over a mean follow-up of 57.5 months, 1 (6%) patient had relapse of PLGE which responded to augmentation of prednisolone dosage. No patients developed alternative gastrointestinal diagnoses. Corticosteroid-induced psychosis, AZA-induced pancytopenia and herpes zoster occurred in three patients. CONCLUSION PLGE is an uncommon manifestation of SLE. Treatment with a combination of prednisolone and AZA is effective and well tolerated.
Adoptive transfer of cytomegalovirus‐specific effector CD4+ T cells provides antiviral protection from murine CMV infection

Cytomegalovirus (CMV) infects a majority of the human population and establishes a life‐long persistence. CMV infection is usually asymptomatic but the virus carries pathogenic potential and causes severe disease in immunocompromised individuals. T‐cell‐mediated immunity plays an essential role in control of CMV infection and adoptive transfer of CMV‐specific CD8+ T cells restores viral immunity in immunosuppressed patients but a role for CD4+ T cells remains elusive. Here, we analyzed in adoptive transfer studies the features and antiviral functions of virus‐specific CD4+ T cells during primary murine CMV (MCMV) infection. MCMV‐specific CD4+ T cells expanded upon MCMV infection and displayed an effector phenotype and function. Adoptive transfer of in vivo activated MCMV‐specific CD4+ T cells to immune‐compromised mice was protective during pathogenic MCMV infection and IFN‐γ was a crucial mediator of this protective capacity. Moreover, co‐transfer of low doses of both MCMV‐specific CD4+ T cells and CD8+ T cells synergized in control of lytic viral replication in immune‐compromised mice. Our data reveal a pivotal antiviral role for virus‐specific CD4+ T cells in protection from pathogenic CMV infection and provide evidence for their antiviral therapeutic potential.
The effects of Doppler broadening and detector resolution on the performance of three-stage Compton cameras.

PURPOSE The authors investigated how the characteristics of the detectors used in a three-stage Compton camera (CC) affect the CC's ability to accurately measure the emission distribution and energy spectrum of prompt gammas (PG) emitted by nuclear de-excitations during proton therapy. The detector characteristics they studied included the material (high-purity germanium [HPGe] and cadmium zinc telluride [CZT]), Doppler broadening (DB), and resolution (lateral, depth, and energy). METHODS The authors simulated three-stage HPGe and CZT CCs of various configurations, detecting gammas from point sources with energies ranging from 0.511 to 7.12 MeV. They also simulated a proton pencil beam irradiating a tissue target to study how the detector characteristics affect the PG data measured by CCs in a clinical proton therapy setting. They used three figures of merit: the distance of closest approach (DCA) and the point of closest approach (PCA) between the measured and actual position of the PG emission origin, and the calculated energy resolution. RESULTS For CCs with HPGe detectors, DB caused the DCA to be greater than 3 mm for 14% of the 6.13 MeV gammas and 20% of the 0.511 MeV gammas. For CCs with CZT detectors, DB caused the DCA to be greater than 3 mm for 18% of the 6.13 MeV gammas and 25% of the 0.511 MeV gammas. The full width at half maximum (FWHM) of the PCA in the ẑ direction for HPGe and CZT detectors ranged from 1.3 to 0.4 mm for gammas with incident energy ranging from 0.511 to 7.12 MeV. For CCs composed of HPGe detectors, the resolution of incident gamma energy calculated by the CC ranged from 6% to 1% for gammas with true incident energies from 0.511 to 7.12 MeV. For CCs composed of CZT detectors, the resolution of gamma energy calculated by the CC ranged from 10% to 1% for gammas with true incident energies from 0.511 to 7.12 MeV. For HPGe and CZT CCs in which all detector effect were included, the DCA was less than 3 mm for 75% and 68% of the detected gammas, respectively, and restricting gammas to those having energy greater than 2.0 MeV increased these percentages to 83% and 77% for HPGe and CZT, respectively. Distributions of the true gamma origins and the PCA after detector characteristics had been included showed good agreement on beam range and some loss of resolution for the lateral profile of the PG emission. Characteristic energy lines were evident in the calculated gamma energy spectrum. CONCLUSIONS The authors found the following: (1) DB is the dominant source of spatial and energy resolution loss in the CCs at all energy levels; (2) the largest difference in the spatial resolution of HPGe and CZT CCs is that the spatial resolution distributions of CZT have broader tails. The differences in the FWHM of these distributions are small; (3) the energy resolution of both HPGe and CZT three-stage CCs is adequate for PG spectroscopy; and (4) restricting the gammas to those having energy greater than 2.0 MeV can improve the achievable image resolution.
Herbivory and pollen limitation at the upper elevational range limit of two forest understory plants of eastern North America

Abstract Studies of species' range limits focus most often on abiotic factors, although the strength of biotic interactions might also vary along environmental gradients and have strong demographic effects. For example, pollinator abundance might decrease at range limits due to harsh environmental conditions, and reduced plant density can reduce attractiveness to pollinators and increase or decrease herbivory. We tested for variation in the strength of pollen limitation and herbivory by ungulates along a gradient leading to the upper elevational range limits of Trillium erectum (Melanthiaceae) and Erythronium americanum (Liliaceae) in Mont Mégantic National Park, Québec, Canada. In T. erectum, pollen limitation was higher at the range limit, but seed set decreased only slightly with elevation and only in one of two years. In contrast, herbivory of T. erectum increased from <10% at low elevations to >60% at the upper elevational range limit. In E. americanum, we found no evidence of pollen limitation despite a significant decrease in seed set with elevation, and herbivory was low across the entire gradient. Overall, our results demonstrate the potential for relatively strong negative interactions (herbivory) and weak positive interactions (pollination) at plant range edges, although this was clearly species specific. To the extent that these interactions have important demographic consequences—highly likely for herbivory on Trillium, based on previous studies—such interactions might play a role in determining plant species' range limits along putatively climatic gradients.
Coronary stent implantation in patients older than 75 years of age: clinical profile and initial and long-term (3 years) outcome.

OBJECTIVE The objective of this study was to compare the initial and long-term outcome of elderly and younger patients after coronary stent implantation. METHODS The evolutions of 76 patients aged >75 years and of 860 patients aged < or =75 years who underwent consecutive stenting (from June 1991 to June 1997) were compared in a cohort study. RESULTS The elderly patients had lower left ventricular ejection fractions (0.58 +/- 0.14 vs 0.61 +/- 0.13; P =.03) and more frequently had unstable angina (78.9% vs 55.3%; P <.0001), previous heart failure (10.5% vs 4.9%; P =.03), and multivessel disease (68.4% vs 58.3%; P =.08). After the procedure, the elderly patients showed a higher inhospital mortality rate (6.6% vs 2.4%; P =.03) and myocardial infarction rate (5.3% vs 1.7%; P =.04). The long-term follow-up period (mean, 3.2 +/- 1.4 years; median, 3.0 years) showed in the elderly a higher mortality rate (15.4% vs 5.8%; P =.006), a lower rate of repeat revascularization (9.2% vs 19.7%; P =.04), and a similar incidence rate of major adverse cardiac events (27.7% vs 28.2%; P =.93). Multivariate analysis of the elderly group identified female gender (hazard ratio, 2.19; 95% CI, 1.18 to 4.06; P =.012) and presence of multivessel disease (hazard ratio, 2.35; 95% CI, 1.05 to 5.26; P =.037) as independent predictors of further events. CONCLUSION Patients aged >75 years have a less favorable baseline profile and higher inhospital and 3-year mortality rates. However, the incidence rate of major adverse cardiac events in the long term is acceptable and similar to that of younger patients.
Fludarabine‐based reduced‐intensity conditioning regimen for hematopoietic stem cell transplantation in primary hemophagocytic lymphohistiocytosis

Primary hemophagocytic lymphohistiocytosis (HLH) is a life‐threatening condition that clinically characterized by fever, hepatosplenomegaly, and cytopenia. Hematopoietic stem cell transplantation (HSCT) is the only curative treatment option for patients diagnosed with primary HLH.
Inflation and Stock Returns at B3

We examine the impact of expected inflation on stock returns. We use inflation forecasts from the Focus survey and real returns of Ibovespa (the index of B3, the Brazilian stock exchange). In our main specification, an increase of 1 percentage point in expected inflation for the next 12 months is associated with a decline of 0.57 percentage points in stock returns. Stock returns react negatively to the 5-year CDS volatility and the VIX index. A simulated portfolio with a strategy based on changes in inflation expectations from 2003 to 2016 has cumulated real returns of 135 percent while cumulated real Ibovespa returns are 48 percent. The strategy implies higher cumulated real returns compared with Ibovespa in 69 percent of the period.
Dynamic Three-Dimensional Ultrasound to Evaluate Scapular Movement Among Manual Wheelchair Users and Healthy Controls.

BACKGROUND A large percentage of individuals with spinal cord injury (SCI) report shoulder pain that can limit independence and quality of life. The pain is likely related to the demands placed on the shoulder by transfers and propulsion. Shoulder pathology has been linked to altered scapular mechanics; however, current methods to evaluate scapular movement are invasive, require ionizing radiation, are subject to skin-based motion artifacts, or require static postures. OBJECTIVE To investigate the feasibility of applying 3-dimensional ultrasound methods, previously used to look at scapular position in static postures, to evaluate dynamic scapular movement. METHODS This study evaluated the feasibility of the novel application of a method combining 2-dimensional ultrasound and a motion capture system to determine 3-dimensional scapular position during dynamic arm elevation in the scapular plane with and without loading. RESULTS Incremental increases in scapular rotations were noted for extracted angles of 30°, 45°, 60°, and 75° of humeral elevation. Group differences were evaluated between a group of 16 manual wheelchair users (MWUs) and a group of age- and gender-matched able-bodied controls. MWUs had greater scapular external rotation and baseline pathology on clinical exam. MWUs also had greater anterior tilting, with this difference further accentuated during loading. The relationship between demographics and scapular positioning was also investigated, revealing that increased age, pathology on clinical exam, years since injury, and body mass index were correlated with scapular rotations associated with impingement (internal rotation, downward rotation, and anterior tilting). CONCLUSIONS Individuals with SCI, as well as other populations who are susceptible to shoulder pathology, may benefit from the application of this imaging modality to quantitatively evaluate scapular positioning and effectively target therapeutic interventions.
Different Modes of Human Papillomavirus DNA Replication during Maintenance

ABSTRACT Human papillomavirus (HPV) begins its life cycle by infecting the basal cells of the epithelium. Within these proliferating cells, the viral genomes are replicated, maintained, and passed on to the daughter cells. Using HPV episome-containing cell lines that were derived from naturally infected cervical tissues, we investigated the mode by which the viral DNAs replicate in these cells. We observed that, whereas HPV16 DNA replicated in an ordered once-per-S-phase manner in W12 cells, HPV31 DNA replicated via a random-choice mechanism in CIN612 cells. However, when HPV16 and HPV31 DNAs were separately introduced into an alternate keratinocyte cell line NIKS, they both replicated randomly. This indicates that HPV DNA is inherently capable of replicating by either random-choice or once-per-S-phase mechanisms and that the mode of HPV DNA replication is dependent on the cells that harbor the viral episome. High expression of the viral replication protein E1 in W12 cells converted HPV16 DNA replication to random-choice replication and, as such, it appears that the mode of HPV DNA replication in proliferating cells is dependent on the presence or the increased level of this protein in the host cell. The implications of these observations on maintenance, latency, and persistence are discussed.
Cyclophilin 40 (CyP-40), Mapping of Its hsp90 Binding Domain and Evidence That FKBP52 Competes with CyP-40 for hsp90 Binding (*)

The structurally related immunophilins cyclophilin 40 (CyP-40) and FKBP52 have been identified as components of the unactivated estrogen receptor. Both immunophilins have a similar molecular architecture that includes a C-terminal segment with a tetratricopeptide repeat (TPR) domain predicted to mediate protein interaction. hsp90 is a common cellular target for CyP-40 and FKBP52. Deletion mutants of CyP-40 fused to glutathione S-transferase were immobilized on glutathione-agarose and then used in a rapid hsp90 retention assay to define regions of the CyP-40 C terminus that are important for hsp90 binding. Our evidence suggests that the TPR domain is not sufficient for stable association of CyP-40 with hsp90 and requires the participation of flanking acidic and basic residues clustered at the N- and C-terminal ends, respectively. Both microdomains are characterized by α-helical structures with segregated hydrophobic and charged residues. Corresponding regions were identified in FKBP52. By preincubating myometrial cytosol with lysates containing bacterially expressed FKBP52, we have shown that FKBP52 competes with CyP-40 for hsp90 binding. Our results raise the possibility of a mutually exclusive association of CyP-40 and FKBP52 with hsp90. This would lead to separate immunophilin-hsp90-receptor complexes and place the estrogen receptor under the control of distinct immunophilin signaling pathways.
Glutathione S-transferase polymorphisms and bone tumor risk in China.

AIM We aimed to study the potential role of GSTM1 and GSTT1 in the risk of osteosarcoma in Chinese population. METHODS We collected 110 osteosarcomas by pathologic examination and 226 controls from the First Affiliated Hospital of Harbin Medical University during December 2008 to December 2010. Genotyping was based upon duplex polymerase-chain-reaction with the PCR-CTPP method. RESULTS Individuals carrying null GSTM1 and GSTT1 had 1.50 and 2.07 fold risks of osteosarcoma when compared with non-null genotypes, respectively. The increased risk associated with the GSTT1 polymorphism seemed more evident among males (Null GSTT1 genotype vs. non-null genotype, adjusted OR= 2.43, 95% CI: 1.29-3.30) than females (adjusted OR =1.66, 95% CI: 1.02-2.78). The increased risk was also more evident among individuals aged 15 years or less (adjusted OR for null GSTT1 genotype vs. non-null genotype = 2.24, 95% CI: 1.20-3.24) than those aged more than 15 years (adjusted OR = 1.82, 95% CI: 1.07-2.95). CONCLUSION Our study of the association between polymorphisms in GSTM1 and GSTTI and the risk of osteosarcoma in a Chinese population provided evidence that null GSTTI might be a useful marker of susceptibility to osteosarcoma development, especially for male sand young age individuals.

Cytological analysis of the periodontal pocket in patients with aggressive periodontitis and chronic periodontitis

Background: Oral exfoliative cytology includes the study and interpretation of the features cells exfoliated from the oral mucosa. The aim of this study was to analyze cytological changes in the periodontal pocket of patients with different clinical stages of aggressive periodontitis (AP) and chronic periodontitis (CP). Materials and Methods: Patients aged 24–54 years, of whom 41 were diagnosed with AP, 40 with CP, sub-classified as mild, moderate and severe periodontitis, and 40 healthy individuals who were the control group. Samples of the epithelium of the periodontal pocket were taken for the cytological study. Results: Superficial and intermediate cell values were significantly greater in patients with AP than in patients with CP or the control group. Histiocyte number was higher in patients with CP than in those with AP, and differed significantly in both types of periodontitis compared to the control group. There were significant differences in polymorphonuclear neutrophil leukocytes when both types of periodontitis were compared to the control group. Microbial flora was statistically higher in patients with CP, and there were differences between patients with periodontitis and the control group. Conclusions: The cytological study demonstrated that patients with AP had greater tissue damage, shown by the increase in intermediate and superficial cells of the epithelium of the periodontal pocket compared to the group of healthy subjects and to a lesser extent, to patients with CP. Only superficial cells made it possible to differentiate the sub-stages of the disease.
Dynamic modelling for distribution networks containing dispersed generations and energy storage devices

The increasing number of distributed generations (DG) in the low voltage (LV) and medium voltage (MV) network has the potential to form a new type of power system, the MicroGrid. These distribution networks can be connected to the main power network or be operated autonomously. The MicroGrid technologies have become one of the hot spots in the research on distributed energy systems. In this paper models of the main dispersed generations such as Photovoltaic Systems and Wind Turbines are described and a simulation platform has been built to represent the steady and dynamic behaviour of the distribution networks. Energy storage technology is regarded as one of the core technologies in MicroGrid, which plays an important role for stabilizing power system and utilizing renewable energy with high efficiency. So the models of energy storage devices have also brought into our simulation platform in order to flat the random fluctuation of the output power of DG. Finally the benchmark network is designed to study the impact of DG and the islanded operation of the MicroGrid.
