Ontogeny of Hepatic Drug Transporters as Quantified by LC‐MS/MS Proteomics

Protein expression of major hepatic uptake and efflux drug transporters in human pediatric (n = 69) and adult (n = 41) livers was quantified by liquid chromatography / tandem mass spectroscopy (LC‐MS/MS). Transporter protein expression of OCT1, OATP1B3, P‐gp, and MRP3 was age‐dependent. Particularly, significant differences were observed in transporter expression (P < 0.05) between the following age groups: neonates vs. adults (OCT1, OATP1B3, P‐gp), neonates or infants vs. adolescents and/or adults (OCT1, OATP1B3, and P‐gp), infants vs. children (OATP1B3 and P‐gp), and adolescents vs. adults (MRP3). OCT1 showed the largest increase, of almost 5‐fold, in protein expression with age. Ontogenic expression of OATP1B1 was confounded by genotype and was revealed only in livers harboring SLCO1B1*1A/*1A. In livers >1 year, tissues harboring SLCO1B1*14/*1A showed 2.5‐fold higher (P < 0.05) protein expression than SLCO1B1*15/*1A. Integration of these ontogeny data in physiologically based pharmacokinetic (PBPK) models will be a crucial step in predicting hepatic drug disposition in children.
Radiographic Identification of Arthroscopically Relevant Acetabular Structures

Background: The anatomy of the acetabulum has been described extensively in the literature, but radiographic acetabular guidelines have not been well established. This study provides a radiographic map of acetabular landmarks in the hip. Purpose/Hypothesis: The purpose of this study was to quantify the precise radiographic location of arthroscopic landmarks around the acetabulum. The hypothesis was that their locations were reproducible despite variability in the anatomy and positioning of pelvic specimens. Study Design: Descriptive laboratory study. Methods: Ten fresh-frozen cadaveric specimens were dissected, and radio-opaque hardware was placed for each landmark of interest. Anteroposterior (AP) and false-profile radiographs were obtained, and measurements were taken using a digital picture archiving and communication system. Results: On AP radiographs, the direct and indirect heads of the rectus femoris were a mean 48.2 ± 4.6 mm and 44.7 ± 4.3 mm proximal to the teardrop line, respectively. The mean radiographic distance between their insertions was 5.0 ± 3.4 mm. Moreover, the anterior inferior iliac spine was a mean 11.5 ± 3.8 mm from the acetabular rim. On false-profile radiographs, the mean distance between the direct and indirect heads of the rectus femoris was 31.4 ± 6.2 mm. The mean distance between the superior margin of the anterior labral sulcus (the psoas-u) and the midpoint of the transverse acetabular ligament was 41.0 ± 5.7 mm. Additionally, the direct and indirect heads of the rectus femoris corresponded to the 2:30 and 1:30 locations on the acetabular clockface, respectively. The midpoint of the transverse acetabular ligament was located at 7 o’clock on the clockface. Conclusion: The most important finding of this study, determined by quantitative measurements, was that the described surgical landmarks had reliable locations on radiographs. Distances between landmarks as well as distances between landmarks and reference lines were reproducible in both AP and false-profile views. Clinical Relevance: An understanding of how acetabular structures present on radiographs could lead to more accurate portal and hardware placement intraoperatively during arthroscopic surgery as well as better preoperative and postoperative assessments.
Collagen-Based Films Containing Liposome-Loaded Usnic Acid as Dressing for Dermal Burn Healing

The aim of this study was assess the effect of collagen-based films containing usnic acid as a wound dressing for dermal burn healing. Second-degree burn wounds were performed in forty-five Wistar rats, assigned into nine groups: COL—animals treated with collagen-based films; PHO—animals treated with collagen films containing empty liposomes; UAL—animals treated with collagen-based films containing usnic acid incorporated into liposomes. After 7, 14, and 21 days the animals were euthanized. On 7th day there was a moderate infiltration of neutrophils, in UAL, distributed throughout the burn wounds, whereas in COL and PHO, the severity of the reaction was slighter and still limited to the margins of the burn wounds. On the 14th day, the inflammatory reaction was less intense in UAL, with remarkable plasma cells infiltration. On the 21st day, there was reduction of the inflammation, which was predominantly composed of plasma cells in all groups, particularly in UAL. The use of the usnic acid provided more rapid substitution of type-III for type-I collagen on the 14th day, and improved the collagenization density on the 21st day. It was concluded that the use of reconstituted bovine type-I collagen-based films containing usnic acid improved burn healing process in rats.
Generation of passive macromodels for lossy multiconductor transmission lines

This paper presents an algorithm for the enforcement of passivity in delay-based multiconductor transmission line macromodels based on the Generalized Method of Characteristics. The algorithm enforces passivity via an iterative procedure based on first-order perturbations. More precisely, the short-circuit admittance matrix of the macromodel is iteratively modified until it becomes positive real. This iterative perturbation is performed on the solutions of a nonlinear eigenvalue problem, whereas the passivity verification is performed using an adaptive frequency sampling process. The proposed technique results in passive, accurate, and efficient macromodels for arbitrary lossy multiconductor transmission lines, which can be synthesized in SPICE netlists for system-level analysis and design.
Different Responses of the Quality Parameters of Coriandrum sativum to Organic Substrate Mixtures and Fertilization

In order to standardize the quality of agricultural products, it is necessary to control the factors affecting plant development, such as plant nutrition. The best results in terms of homogeneity of the quality of vegetable crops were achieved using inert substrates and application of nutrients; however, production costs are high due to the cost of irrigation systems and substrate management and importation. This work aims to evaluate the effect of the local substrate mix and the amount of organic fertilizer on different quality parameters of coriander. To evaluate the quality of coriander, we considered different parameters such as size, biomass, antioxidant capacity and aroma (evaluated by volatile compounds detection with gas chromatography). The results show that the culture system differentially affects each parameter, and the compounds associated with the aroma of coriander and the diameter of plants are sensitive to the culture system, while the length of plants, number of leaves and antioxidant activity are not affected by the concentration of fertilizer. Moreover, organic farming conditions do not reduce quality parameters of the crops when using adequate fertilization. Additionally, local substrates would be practical substitutes for expensive importations.
Probabilistic health risk assessment of polycyclic aromatic hydrocarbons and polychlorinated biphenyls in urban soils from a tropical city of India

Distribution of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in urban soils, and their risk for humans was evaluated and presented in this article. The average concentration of ∑16PAHs, ∑carcinogenic PAHs, ∑28PCBs and ∑dioxin-like PCBs was 631.6 ± 244.5 μg kg−1, 568.8 ± 238.8 μg kg−1, 11.57 ± 2.00 μg kg−1 and 2.58 ± 0.34 μg kg−1, respectively. Environmental and human health risk assessment parameters such as benzo(a)pyrene total potency equivalent (BaP TPE), index of additive cancer risk (IACR), life time average daily dose (LADD) and incremental lifetime cancer risk (ILCR) have been estimated and discussed. The average benzo(a)pyrene total potency equivalent (BaP TPE) estimate was 0.194 mg kg−1 and ranging between 8.9×10−4 to 0.87 mg kg−1. The incremental life time cancer risk (ILCR) of PAHs through soil ingestion for adults and children was estimated as 8.1×10−6 and 4.2×10−5, respectively. However, the cancer risk (ILCR) from non-dioxin-like PCBs and dioxin-like PCBs for adults and children ranged between 3.31×10−8 to 1.741×10−7 and 1.46×10−5 to 7.56×10−5, respectively. These estimated risks were lower than acceptable limits, based on incremental cancer risk from soil exposure. Overall, index of additive cancer risk (IACR) and hazard quotient (HQ) for PAHs and PCBs was lower than safe limit of 1, indicating no environmental and human health risk from PAHs and PCBs in this area of study.
Structural changes in muscle crossbridges accompanying force generation

We have investigated the structure of the crossbridges in muscles rapidly frozen while relaxed, in rigor, and at various times after activation from rigor by flash photolysis of caged ATP. We used Fourier analysis of images of cross sections to obtain an average view of the muscle structure, and correspondence analysis to extract information about individual crossbridge shapes. The crossbridge structure changes dramatically between relaxed, rigor, and with time after ATP release. In relaxed muscle, most crossbridges are detached. In rigor, all are attached and have a characteristic asymmetric shape that shows strong left-handed curvature when viewed from the M-line towards the Z-line. Immediately after ATP release, before significant force has developed (20 ms) the homogeneous rigor population is replaced by a much more diverse collection of crossbridge shapes. Over the next few hundred milliseconds, the proportion of attached crossbridges changes little, but the distribution of the crossbridges among different structural classes continues to evolve. Some forms of attached crossbridge (presumably weakly attached) increase at early times when tension is low. The proportion of several other attached non-rigor crossbridge shapes increases in parallel with the development of active tension. The results lend strong support to models of muscle contraction that have attributed force generation to structural changes in attached crossbridges.
Dimensions of work satisfaction as predictors of commitment type (Измерения удовлетворенности трудом как показатели типа обязательств)

This study of hospital nurses (n = 154) examined the influence of dimensions of work satisfaction on types of organizational commitment. Significant results were found for the two affective commitment types tested but not for the instrumental type evaluated. The results indicate that satisfaction with professional status was a significant predictor of moral commitment. Dissatisfaction with organizational policies, autonomy, and professional status were significant predictors of alienative commitment. None of the dimensions of work satisfaction were predictors of calculative commitment. The results of this study suggest that understanding how various factors impact the nature and the form of an individual's organizational commitment is worth the effort. If managers do not know what causes an attitude to take on a particular form, they cannot accurately predict what behavior might follow.
Polyploidy, phylogeography and Pleistocene refugia of the rockfern Asplenium ceterach: evidence from chloroplast DNA

Chloroplast DNA sequences were obtained from 331 Asplenium ceterach plants representing 143 populations from throughout the range of the complex in Europe, plus outlying sites in North Africa and the near East. We identified nine distinct haplotypes from a 900 bp fragment of trnL‐trnF gene. Tetraploid populations were encountered throughout Europe and further afield, whereas diploid populations were scarcer and predominated in the Pannonian‐Balkan region. Hexaploids were encountered only in southern Mediterranean populations. Four haplotypes were found among diploid populations of the Pannonian‐Balkans indicating that this region formed a northern Pleistocene refugium. A separate polyploid complex centred on Greece, comprises diploid, tetraploid and hexaploid populations with two endemic haplotypes and suggests long‐term persistence of populations in the southern Mediterranean. Three chloroplast DNA (cpDNA) haplotypes were common among tetraploids in Spain and Italy, with diversity reducing northwards suggesting expansion from the south after the Pleistocene. Our cpDNA and ploidy data indicate at least six independent origins of polyploids.
Emergence of Polyfunctional CD8+ T Cells after Prolonged Suppression of Human Immunodeficiency Virus Replication by Antiretroviral Therapy

ABSTRACT Progressive human immunodeficiency virus type 1 (HIV-1) infection is often associated with high plasma virus load (pVL) and impaired CD8+ T-cell function; in contrast, CD8+ T cells remain polyfunctional in long-term nonprogressors. However, it is still unclear whether CD8+ T-cell dysfunction is the cause or the consequence of high pVLs. Here, we conducted a longitudinal functional and phenotypic analysis of virus-specific CD8+ T cells in a cohort of patients with chronic HIV-1 infection. During the initiation and maintenance of successful antiretroviral therapy (ART), we assessed whether the level of pVL was associated with the degree of CD8+ T-cell dysfunction. Under viremic conditions, HIV-specific CD8+ T cells were dysfunctional with respect to cytokine secretion (gamma interferon, interleukin-2 [IL-2], and tumor necrosis factor alpha), and their phenotype suggested limited potential for proliferation. During ART, cytokine secretion by HIV-specific CD8+ T cells was gradually restored, IL-7Rα and CD28 expression increased dramatically, and PD-1 levels declined. Thus, prolonged ART-induced reduction of viral replication and, hence, presumably antigen exposure in vivo, allows a significant functional restoration of CD8+ T cells with the appearance of polyfunctional cells. These findings indicate that the level of pVL as a surrogate for antigen load has a dominant influence on the phenotypic and functional profile of virus-specific CD8+ T cells.
Asymptotic phase synchronization of Kuramoto model with weighted non-symmetric interconnections: A case study

We consider a synchronization problem for the Kuramoto oscillators using a linear modeling framework. For the general case of Kuramoto model with directed and weighted graph of interconnections we show that the problem of existence of phase locked solutions is equivalent to an algebraic problem of existence of a corresponding matrix with a single purely imaginary eigenvalue. In the case of complete input- output weighted graphs this approach allows to give analytical expressions both for the synchronization frequencies and the phase locked solutions and, on the next step, to analyze their stability properties.
Predicting Risk Factors for Intimate Partner Violence Among College Student Veterans of the Iraq and Afghanistan Wars

PREDICTING RISK FACTORS FOR INTIMATE PARTNER VIOLENCE 4 The current conflicts in Afghanistan and Iraq present unique risk factors for military personnel that increase the likelihood of psychological distress and concomitant consequences related to trauma. Several studies have found that the stress brought about by financial difficulties, unemployment, and the need to renegotiate roles and responsibilities with spouses following discharge increases the likelihood of relationship strain and even intimate partner violence in the veteran population. This study was undertaken to determine the challenges related to maintaining healthy relationships for recent tour college student veterans. Psychological distress, substance use, and hypermasculine attitudes were explored as risk factors for intimate violence. Social support was found to be a protective buffer against psychological aggression. However, approximately a third of college student veterans reported low social support along with symptoms of distress, placing them at elevated risk for partner abuse. The current article explores models for predicting risk for perpetrating aggression in recent tour college student veterans and concludes that culturally tailored programs and services are needed.
Random breakage and reunion chromosome aberration formation model; an interaction–distance version based on chromatin geometry

Abstract. Purpose : Using published FISH data for chromosome aberration production in human fibroblasts by hard X-rays to test a breakage-and-reunion model. Methods : The model assumed pairwise misrejoining, random apart from proximity e ffects, of DNA double-strand break (DSB) free ends. CAS (chromosome aberration simulator) Monte Carlo computer software implementing the model was modified to use a distance algorithm for misrejoining instead of using DSB interaction sites. The modification (called CAS2) allowed a somewhat more realistic approach to large-scale chromatin geometry, chromosome territories and proximity effects. It required adding a third adjustable parameter, the chromosome territory intersection factor, quantifying the amount of intertwining among different chromosomes. Results : CAS2 gave somewhat better results than CAS. A reasonable fit with a few discrepancies was obtained for the frequencies at three different radiation doses of many different aberration types and of aberrations involving various specific chromosomes in a large data set using one-paint FISH scoring. The optimal average chromosome territory intersection factor was ~1.1, indicating that, for an arbitrarily chosen location in the nucleus, on average slightly more than two chromosomes have very nearby loci. Without changing the three parameter values, a fit was also obtained for a corresponding, smaller, two-paint data set. Conclusions : A random breakage-and-reunion model incorporating proximity effects by using a distance algorithm gave acceptable approximations for many details of hard X-ray aberration patterns. However, enough discrepancies were found that the possibility of an additional or alternate formation mechanism remains.
The Impact of Cigarette Smoking on 24‐Hour Blood Pressure, Inflammatory and Hemostatic Activity, and Cardiovascular Risk in Japanese Hypertensive Patients

The aim of the study was to assess the impact of current smoking on 24‐hour blood pressure (BP) and inflammatory and hemostatic activity and thereby the incidence of cardiovascular disease (CVD) in Japanese hypertensive patients. A total of 810 hypertensive patients (mean age 72 years; 38% men) were prospectively followed‐up (2799 person‐years). During the follow‐up, 66 cases of CVD occurred (stroke, 55; myocardial infarction, 7; both, 4). At baseline, the current smokers (n=166) had higher levels of high‐sensitivity C‐reactive protein (hs‐CRP) (0.21 mg/dL vs 0.14 mg/dL) and plasminogen activator inhibitor‐1 (PAI‐1) (46.1 ng/mL vs 37.8 ng/mL; both P=.001), but not of 24‐hour BP, compared with nonsmokers. Using a Cox regression analysis, current smoking was independently associated with an increased risk of CVD (hazard ratio [HR], 2.6; P<.01), and the risk was substantially higher in women (HR, 6.1; P<.001) than in men (HR, 1.4; P=.41). The CVD risk of current smokers was magnified when it was accompanied with high hs‐CRP (highest quartile range, ≥0.40 mg/L) or PAI‐1 levels (≥58.9 ng/mL) compared with that in smokers with low hs‐CRP or PAI‐1 levels (both P<.05). Among hypertensive patients, current smokers had increased risk of CVD events, and the increase was more prominent when accompanied by circulatory inflammatory and hemostatic abnormalities.

Evolutionary inheritance of elemental stoichiometry in phytoplankton

The elemental composition of phytoplankton is a fusion of the evolutionary history of the host and plastid, resulting in differences in genetic constraints and selection pressures associated with environmental conditions. The evolutionary inheritance hypothesis predicts similarities in elemental composition within related taxonomic lineages of phytoplankton. To test this hypothesis, we measured the elemental composition (C, N, P, S, K, Mg, Ca, Sr, Fe, Mn, Zn, Cu, Co, Cd and Mo) of 14 phytoplankton species and combined these with published data from 15 more species from both marine and freshwater environments grown under nutrient-replete conditions. The largest differences in the elemental profiles of the species distinguish between the prokaryotic Cyanophyta and primary endosymbiotic events that resulted in the green and red plastid lineages. Smaller differences in trace element stoichiometry within the red and green plastid lineages are consistent with changes in trace elemental stoichiometry owing to the processes associated with secondary endosymbioses and inheritance by descent with modification.
Reliable Neuronal Systems: The Importance of Heterogeneity

For every engineer it goes without saying: in order to build a reliable system we need components that consistently behave precisely as they should. It is also well known that neurons, the building blocks of brains, do not satisfy this constraint. Even neurons of the same type come with huge variances in their properties and these properties also vary over time. Synapses, the connections between neurons, are highly unreliable in forwarding signals. In this paper we argue that both these fact add variance to neuronal processes, and that this variance is not a handicap of neural systems, but that instead predictable and reliable functional behavior of neural systems depends crucially on this variability. In particular, we show that higher variance allows a recurrently connected neural population to react more sensitively to incoming signals, and processes them faster and more energy efficient. This, for example, challenges the general assumption that the intrinsic variability of neurons in the brain is a defect that has to be overcome by synaptic plasticity in the process of learning.

Absence of CD43 Fails to Alter T Cell Development and Responsiveness1

Genetic elimination of CD43 has been associated with increased T cell adhesiveness and T cell hyperresponsiveness to mitogens and alloantigens. Therefore, we investigated whether T cell development was perturbed in CD43-deficient mice by breeding CD43null mice with male Ag (Hy)-specific TCR-transgenic mice. Neither positive nor negative thymic selection of male Ag-specific T cells were affected by CD43 status. Furthermore, we did not observe a substantial or consistent hyperresponsive pattern in HY-CD43null lymph node cells compared with littermate HY-CD43+/− lymph node cells upon analysis of in vitro T cell stimulation with male Ag or mitogen. These observations challenged original conclusions associating absence of CD43 with T cell hyperresponsiveness and led us to re-examine this association. Reported phenotypes of CD43null mice have been based on mice with a mixed 129×C57BL/6 genetic background. To exclude a possible influence of genetic background differences among individual mice we analyzed CD43null littermates that had been back-bred onto the C57BL/6 background for seven to eight generations. We found that CD43+ and CD43null littermates with the C57BL/6 background exhibited no differences in response to mitogen or alloantigen, thereby establishing that T cell hyperresponsiveness is not a general correlate of CD43 absence.
