Correlation of CD4 T Cell Count and Plasma Viral Load with Reproductive Tract Infections/Sexually Transmitted Infections in HIV Infected Females.

BACKGROUND Sexually transmitted infections (STIs) plays a major role in the spread of Human immunodeficiency virus (HIV) due to common route of transmission. These infections display an epidemiological synergy with HIV. AIM The aim of this study was to analyse the correlation of CD4 T lymphocyte cell count, HIV-1 plasma viral load with Reproductive tract infections/Sexually transmitted infections (RTIs/STIs) in HIV infected females. MATERIALS AND METHODS The study included 60 HIV infected females. An informed consent was taken from all the study subjects. Relevant specimens (genital specimen and blood) were collected for laboratory diagnosis of various RTIs/STIs, CD4 cell count and plasma viral load estimation. RESULTS Mean CD4 count of females with bacterial vaginosis, vaginal candidiasis, trichomoniasis, syphilis and herpes simplex infection were lower as compared to other HIV infected cases and mean plasma viral load of bacterial vaginosis, vaginal candidiasis, trichomoniasis and syphilis were higher as compared to other HIV infected cases but this difference was not statistically significant. CONCLUSION This study highlights the importance of routine screening for STIs/RTIs of all the HIV infected females for RTIs/STIs irrespective of CD4 cell count and plasma viral load.
Musculoskeletal Biopsies Using Computed Tomography Fluoroscopy

Objective: To determine the diagnostic yield, accuracy, and safety of computed tomography (CT) fluoroscopy guidance for musculoskeletal biopsies. Materials and Methods: A retrospective analysis of musculoskeletal biopsies performed with CT fluoroscopy guidance over a 2-year period was made. Data collected were biopsy sites, CT fluoroscopic times, and biopsy results. Results were categorized as the following: positive, negative (but diagnostic), or nondiagnostic. Reference standard consisted of 5 years of follow-up to verify results. Results: Ninety-five CT fluoroscopy-guided musculoskeletal biopsies were performed. Bone biopsies comprised 83% (79/95), and soft tissue biopsies comprised 17% (16/95). The mean age was 54 years (range, 16-90 years); 40.0% (38/95) were male subjects, and 60.0% (57/95) were female subjects. For all subjects, CT fluoroscopic times ranged from 2 to 310 seconds, with a mean time of 63 seconds and a median time of 34 seconds. The diagnostic yield was 96% (91/95), with a nondiagnostic result in 4% (4/95) of subjects. Diagnostic biopsy specimens showed a positive result in 63% (60/95) of subjects and a negative but diagnostic result in 33% (31/95) of subjects. There were no major complications. Conclusions: Computed tomography fluoroscopic-guided musculoskeletal biopsies show a high diagnostic yield and are accurate and safe. The biopsy results are similar or superior to other published reports using conventional CT guidance with only a small overall fraction being nondiagnostic. The benefits of real-time imaging are at the cost of operator exposure to ionizing radiation and the risk of potentially high exposures to both patient and operator. The impact on indications for which lesions are most amenable to percutaneous biopsy using CT fluoroscopy and procedure time has yet to be determined.
Fabrication, Physicochemical Characterizations and Electrical Conductivity Studies of Modified Carbon Nanofiber-Reinforced Epoxy Composites: Effect of 1-Butyl-3-Methylimidazolium Tetrafluoroborate Ionic Liquid

ABSTRACT This study presents the fabrication of carbon nanofiber-reinforced epoxy nanocomposites using 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid as filler dispersant. FTIR and XRD measurements were utilized to assess structural attributes and crystallographic change in the composites. In addition, morphological studies were performed by field emission scanning electron microscope while the extent of miscibility between epoxy and IL was computed by Accelrys Materials Studio Software. The conductivity measurement was performed by two point impedance analyzer and result demonstrated increase in the electrical conductivity from ∼10−7 to ∼10−5 S cm−1 compared to pristine epoxy composite. GRAPHICAL ABSTRACT
Balanced Growth Despite Uzawa

Evidence for the United States suggests balanced growth despite falling investment-good prices and less than unitary elasticity of substitution between capital and labor. This is inconsistent with the Uzawa Growth Theorem. We extend Uzawa's theorem to show that introducing human capital accumulation in the standard way does not resolve the puzzle. However, balanced growth is possible if education is endogenous and capital is more complementary with schooling than with raw labor. We describe balanced growth paths for several neoclassical growth models with capital-augmenting technological progress and endogenous schooling. The balanced growth path in an overlapping-generations model in which individuals choose their time in school matches key features of the U.S. record.
Not Merely Experiential: Unconscious Thought Can Be Rational

Individuals often form more reasonable judgments from complex information after a period of distraction vs. deliberation. This phenomenon has been attributed to sophisticated unconscious thought during the distraction period that integrates and organizes the information (Unconscious Thought Theory; Dijksterhuis and Nordgren, 2006). Yet, other research suggests that experiential processes are strengthened during the distraction (relative to deliberation) period, accounting for the judgment and decision benefit. We tested between these possibilities, hypothesizing that unconscious thought is distinct from experiential processes, and independently contributes to judgments and decisions during a distraction period. Using an established paradigm, Experiment 1 (N = 319) randomly induced participants into an experiential or rational mindset, after which participants received complex information describing three roommates to then consider consciously (i.e., deliberation) or unconsciously (i.e., distraction). Results revealed superior roommate judgments (but not choices) following distraction vs. deliberation, consistent with Unconscious Thought Theory. Mindset did not have an influence on roommate judgments. However, planned tests revealed a significant advantage of distraction only within the rational-mindset condition, which is contrary to the idea that experiential processing alone facilitates complex decision-making during periods of distraction. In a second experiment (N = 136), we tested whether effects of unconscious thought manifest for a complex analytical reasoning task for which experiential processing would offer no advantage. As predicted, participants in an unconscious thought condition outperformed participants in a control condition, suggesting that unconscious thought can be analytical. In sum, the current results support the existence of unconscious thinking processes that are distinct from experiential processes, and can be rational. Thus, the experiential vs. rational nature of a process might not cleanly delineate conscious and unconscious thought.
Nonsegmented PSpice Circuit Model of GaN HEMT With Simulation Convergence Consideration

To solve the simulation convergence problem of enhancement mode gallium nitride high-electron mobility transistor (GaN HEMT) models, this paper proposes a nonsegmented model for GaN HEMT, which uses nonsegmented, smooth continuous equations to describe the static and dynamic characteristics of GaN HEMT. Furthermore, the static characteristic of GaN HEMT obtained by the nonsegmented model is verified by comparing the simulation curves with the static curves provided in datasheet; and the dynamic characteristic obtained by the nonsegmented model is verified by comparing the simulation result with the experimental result based on double pulse test platform. Moreover, to prove the good performance on simulation convergence of the proposed nonsegmented GaN HEMT model, the full-bridge dc–ac inverter with four GaN HEMTs has been employed as an example; the simulation result shows the good convergence of the inverter compared to the conventional segmented GaN HEMT model, which make it possible and flexible to research the power converters with GaN HEMTs by simulation way.
Asexual Reproduction Does Not Apparently Increase the Rate of Chromosomal Evolution: Karyotype Stability in Diploid and Triploid Clonal Hybrid Fish (Cobitis, Cypriniformes, Teleostei)

Interspecific hybridization, polyploidization and transitions from sexuality to asexuality considerably affect organismal genomes. Especially the last mentioned process has been assumed to play a significant role in the initiation of chromosomal rearrangements, causing increased rates of karyotype evolution. We used cytogenetic analysis and molecular dating of cladogenetic events to compare the rate of changes of chromosome morphology and karyotype in asexually and sexually reproducing counterparts in European spined loach fish (Cobitis). We studied metaphases of three sexually reproducing species and their diploid and polyploid hybrid clones of different age of origin. The material includes artificial F1 hybrid strains, representatives of lineage originated in Holocene epoch, and also individuals of an oldest known age to date (roughly 0.37 MYA). Thereafter we applied GISH technique as a marker to differentiate parental chromosomal sets in hybrids. Although the sexual species accumulated remarkable chromosomal rearrangements after their speciation, we observed no differences in chromosome numbers and/or morphology among karyotypes of asexual hybrids. These hybrids possess chromosome sets originating from respective parental species with no cytogenetically detectable recombinations, suggesting their integrity even in a long term. The switch to asexual reproduction thus did not provoke any significant acceleration of the rate of chromosomal evolution in Cobitis. Asexual animals described in other case studies reproduce ameiotically, while Cobitis hybrids described here produce eggs likely through modified meiosis. Therefore, our findings indicate that the effect of asexuality on the rate of chromosomal change may be context-dependent rather than universal and related to particular type of asexual reproduction.
Diffraction study of mechanical properties and residual stresses resulting from surface processing of polycrystalline materials.

Methodology of stress measurements with multireflection grazing incidence method (MGIXD)was investigated and developed. The parallel beam geometry was applied. The incident beam in classicaldiffractometers was collimated by Gobel mirror and the tests of parallel configuration were performed for Alpowder. Results confirmed that both statistical error and the misalignment error can be reduced when theGobel mirror is used. Physical factors were taken into account in XSA (X-ray stress analysis): Lorentzpolarizationand absorption factor (LPA) and also refraction correction (RC). Results showed that theinfluence of LPA correction is minor in XSA but the RC can significantly influence analysis. In the thesisthe issue of RC was considered and compared with approaches presented in the literature. In the thesistwo theoretical developments of the MGIXD method were presented: the procedure of c/a parameterdetermination and the influence of stacking faults on the results was taken into account. It was shown thatboth developments significantly improves the quality of experimental data analysis. In the present work theproblem of X-ray stress factors (XSF) used for the interpretation of XSA results was studied. Differenttheoretical grain elasto-plastic interaction models were considered and applied in XSA. Verification of theXSF was during tensile test for austenitic stainless steel and for the isotropic sample. Anisotropy of XSFwas also observed in: ground Ni alloy, polished austenitic stainless steel and CrN coating. The resultsshows that Reuss and free surface grain interaction models are in the best agreement with theexperimental results. Finally the MGIXD method was verified using synchrotron radiation and 3 differentwavelengths. The methodology was developed to treat data not only for different incident angles but alsousing simultaneously different wavelengths. Stresses vs. z – ‘real depth’ was calculated using the inverseLaplace transform applied to polynomial function. Wiliamson-Hall analysis was applied for collected data.Next multireflection method was applied for the energy dispersion diffraction measurements in which whitebeam containing radiation having different wavelengths was used (λ (Ǻ): 0.3–0.18/ E (keV): 40-68). Thestress analysis was performed using three different methods: standard sin2ψ method, Universal plotmethod and by using multireflection analysis. In the range of penetration depth to 0-15 μm theconvergence of the results obtained from different methods was gained. Moreover the synchrotron dataperfectly agree with the results obtained on laboratory diffractometer (Cu Kα radiation) close to the surface.For depth larger than 14 μm the experimental points exhibit significant spread and do not agree with theresults of standard method
Complete reducibility and separability

Let G be a reductive linear algebraic group over an algebraically closed field of characteristic p > 0. A subgroup of G is said to be separable in G if its global and infinitesimal centralizers have the same dimension. We study the interaction between the notion of separability and Serre's concept of G-complete reducibility for subgroups of G. The separability hypothesis appears in many general theorems concerning G-complete reducibility. We demonstrate that many of these results fail without this hypothesis. On the other hand, we prove that if G is a connected reductive group and p is very good for G, then any subgroup of G is separable; we deduce that under these hypotheses on G, a subgroup H of G is G-completely reducible provided the Lie algebra of G is semisimple as an H-module.Recently, Guralnick has proved that if H is a reductive subgroup of G and C is a conjugacy class of G, then the intersection of C and G is a finite union of H-conjugacy classes. For generic p -- when certain extra hypotheses hold, including separability -- this follows from a well-known tangent space argument due to Richardson, but in general, it rests on Lusztig's deep result that a connected reductive group has only finitely many unipotent conjugacy classes. We show that the analogue of Guralnick's result is false if one considers conjugacy classes of n-tuples of elements from H for n > 1.
News video story sentiment classification and ranking

In this paper, we present a novel approach for news video story sentiment analysis. Two research challenges are addressed: news video story sentiment classification and ranking. For classification, a graph based semi-supervised learning approach is utilized to classify the news stories into sentiment classes. Graph based semi-supervised learning is able to tackle the problem of lacking labeled data. After classification, two sentiment classes are obtained: positive and negative. In order to project the news videos into sentiment space, a multimodal approach by fusing the text sentiment and visual representation scores is adopted to rank the videos in each class. For sentiment representation, inter and intra sentiment class analysis is conducted based on affinity propagation clustering and PageRank algorithm. A user study is conducted to evaluate the video ranking performance. The experimental results on the selected topics are promising and demonstrate the proposed approach is effective.
Saphenous Vein Coronary Artery Bypass in Patients with “Preinfarction Angina”

Among the first 400 patients undergoing saphenous vein coronary artery bypass at Stanford Medical Center, 67 (18%) met criteria for “preinfarction angina”. Angina was alleviated and possible myocardial infarction was prevented utilizing these surgical technics. The overall operative mortality rate in the preinfarction angina patients was 10.4%, which contrasted strikingly with a 1.5% operative mortality for elective coronary artery bypass at Stanford. Six of the seven operative deaths resulted from myocardial infarction, two of which were related to technical factors. Operative mortality appeared to be related to degree of preoperative congestive heart failure and hypotension, pump time, sex, and number of atherosclerosis risk factors present. Fifty-two of the 60 patients leaving the hospital (87%) received good symptomatic benefit from surgery, including no late infarction, over a 6.8 month mean follow-ulp period. The late death rate was 3.3%, and the late infarction rate was 10% during the follow-up period. Angina can be alleviated and impending myocardial infarction may be prevented with aggressive surgical intervention.
Dietary Management of Skin Health: The Role of Genistein

In women, aging and declining estrogen levels are associated with several cutaneous changes, many of which can be reversed or improved by estrogen supplementation. Two estrogen receptors—α and β—have been cloned and found in various tissue types. Epidermal thinning, declining dermal collagen content, diminished skin moisture, decreased laxity, and impaired wound healing have been reported in postmenopausal women. Experimental and clinical studies in postmenopausal conditions indicate that estrogen deprivation is associated with dryness, atrophy, fine wrinkling, and poor wound healing. The isoflavone genistein binds to estrogen receptor β and has been reported to improve skin changes. This review article will focus on the effects of genistein on skin health.
A microwave single-pole double-throw T/R switch integrating bandpass response

This paper proposes a microwave single-pole double-throw (SPDT) T/R switch integrating bandpass response. The series-parallel configuration of p-i-n diodes embedded into the impedance matching circuit is proposed to combine two quasi-elliptic response bandpass filters to constitute the proposed SPDT T/R switch. To validate our design approach, a proposed SPDT T/R switch integrating bandpass response is designed and fabricated with a central frequency of 1.25 GHz and a 3 dB fractional bandwidth of 16%. Low insertion loss in the on state and good isolation in the off state are achieved. The switch size including bias circuits but excluding feeding lines is 0. 447λg × 0. 134λg.
Managing the risk of transmission of variant Creutzfeldt Jakob disease by blood products

Whereas plasma‐derived clotting factor concentrates now have a very good safety record for not being infectious for lipid enveloped viruses, concern has arisen about the possibility that prion diseases might be transmitted by blood products. There is epidemiological evidence that classical sporadic Creutzfeld Jakob disease (CJD) is not transmitted by blood transfusion. There is now good evidence that the abnormal prion associated with variant CJD can be transmitted by transfusion of fresh blood components and infect recipients. To reduce the risk of the pathological prion in the UK infecting recipients of clotting factor concentrates, these are now only manufactured from imported plasma collected from countries where there has not been bovine spongiform encephalopathy (BSE) in cattle and the risk of variant CJD in the population is, therefore, considered negligible. The safety of these concentrates is also enhanced because prion protein is, to an appreciable extent, excluded by the manufacturing process from the final product. To help reduce the chance of prion transmission by fresh blood products, donations are leucodepleted, there is increasing use of imported fresh frozen plasma (especially for treating children) and potential donors, who have been recipients of blood since 1980 (the beginning of the BSE epidemic in cattle) are deferred.

Survival rates of sinonasal squamous cell carcinoma with the new AJCC staging system.

OBJECTIVE To investigate the validity of the sixth edition of the American Joint Committee on Cancer (AJCC) staging system for sinonasal squamous cell carcinoma. DESIGN A 15-year retrospective case series review. SETTING Multicenter study from tertiary care facilities. PATIENTS Data from 113 patients diagnosed as having and treated for sinonasal squamous cell carcinoma from September 1988 through August 2003 were retrieved. Ninety patients followed up for at least 12 months were included in the study. MAIN OUTCOME MEASURES The TNM staging system and survival rates were analyzed using the Kaplan-Meier method to determine the mean, disease-free, and 5-year survival statistics. The effect of tumor stage on overall survival was assessed with stages defined by the fifth and sixth editions of the AJCC staging systems. RESULTS The overall 5-year survival rate was 59.5%. According to the sixth edition, the survival rates of patients with stages III, IVA, and IVB tumors showed a significant difference (P = .002). In 32 cases, the stages were changed in accordance with the criteria in the sixth edition. The group in which the stage changed from III (fifth edition) to IVA (sixth edition) showed a worse survival rate than the group in which the stage did not change, although the difference was statistically insignificant. The 5-year disease-free survival rates of the group in which the stage did not change and of the group in which the stage changed from III (fifth edition) to IVA (sixth edition) were 64% and 34%, respectively (P = .08). Local recurrence was more frequently observed in the group in which the stage changed from III (fifth edition) to IVA (sixth edition). CONCLUSION The new AJCC staging system seems to be more accurate in predicting the survival rates for patients with advanced but surgically resectable sinonasal squamous cell carcinoma (stage IVA).
Core structure of ⅓〈1120〉 screw dislocations on basal and prismatic planes in h.c.p. metals: An atomistic study

Abstract Atomistic studies of stacking faults and dislocation cores in several h.c. p. metals have been carried out using recently constructed empirical many-body potentials. These potentials are fitted so as to reproduce the correct c/a ratios and allow us to study the effect of the deviation from close packing upon the dislocation properties. First, the possible metastable stacking faults on basal and prism planes have been investigated using the concept of γ-surfaces. Metastable stacking faults may exist on both these types of plane. On basal planes the corresponding displacement vector is always the same, determined by the crystal symmetry. However, on prism planes it varies with the material. The atomistic calculations of the cores of screw dislocations with the ⅓ Burgers vector in Mg, Ti and Be indeed show dissociations on both basal and prism planes, in accordance with the findings of the studies of stacking faults. Using these results we then analyse the energy balance between dissociations o.
