[Low dose of sublingual misoprostol (12.5 µg) for labor induction].

PURPOSE To describe the maternal and perinatal outcomes after the use of 12.5 µg of sublingual misoprostol for labor induction in women with term pregnancy and a live fetus. METHODS We conducted a multicenter, open and non-randomized clinical trial during the period from July to December 2009. We included 30 pregnant women with an indication for labor induction at term, carrying a live fetus, with a Bishop score of six or less, cephalic presentation, estimated fetal weight of less than 4,000 g and an amniotic fluid index greater than five. We excluded women with a previous uterine scar, non-reassuring fetal status, congenital anomalies, multiple pregnancy, intrauterine growth restriction, genital bleeding, and contraindications of vaginal delivery. A tablet of 12.5 µg sublingual misoprostol was administered every six hours, until the beginning of labor, with the maximum of eight doses. RESULTS Labor was successfully induced in 90% of pregnant women. The mean interval between the first dose and the onset of uterine contractions and delivery was 14.3±11.7 hours and 25.4±13 hours, respectively. The frequency of vaginal delivery was 60%. Uterine tachysystole occurred in two pregnant women, being reversed in both cases without the need for cesarean section. Meconium-stained amniotic fluid was observed in four patients, and an Apgar score of less than 7 at five minutes in only one newborn. CONCLUSION Maternal and perinatal outcomes were favorable after induction of labor with sublingual misoprostol at a dose of 12.5 µg every six hours. However, controlled trials are needed to compare this regimen with other doses and routes of administration.
Long-term microfouling on commercial biocidal fouling control coatings

The current study investigated the microbial community composition of the biofilms that developed on 11 commercial biocidal coatings, including examples of the three main historic types, namely self-polishing copolymer (SPC), self-polishing hybrid (SPH) and controlled depletion polymer (CDP), after immersion in the sea for one year. The total wet weight of the biofilm and the total bacterial density were significantly influenced by all coatings. Pyrosequencing of 16S rRNA genes revealed distinct bacterial community structures on the different types of coatings. Flavobacteria accounted for the dissimilarity between communities developed on the control and SPC (16%) and the control and SPH coatings (17%), while Alphaproteobacteria contributed to 14% of the dissimilarity between the control and CDP coatings. The lowest number of operational taxonomic units was found on Intersmooth 100, while the lowest biomass and density of bacteria was detected on other SPC coatings. The experiments demonstrated that the nature and quantity of biofilm present differed from coating to coating with clear differences between copper-free and copper-based biocidal coatings.
Spanish adaptation of the Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39).

AIM The stroke and aphasia quality of life scale-39 is an interviewer administered questionnaire that has been developed and validated in the United Kingdom to be applied to patients with chronic aphasia as a consequence of a stroke. The objective of this article was to translate the Stroke and Aphasia Quality of Life-39 Scale (SAQOL-39) into Spanish language, and evaluate its acceptability and reliability. METHODS The cross-cultural adaptation of the SAQOL-39 into Spanish was carried out by following the translation and back-translation method. Twenty three patients with long-term aphasia due to stroke were tested. The patients were interviewed twice in a period from 2 to 12 days. The acceptability of the Spanish SAQOL-39 was evaluated by examining the floor/ceiling effects and the missing data. The reliability was assessed by Cronbach's alpha (internal consistence) and intraclass correlation coefficients (test-retest reliability) for the overall scale and its subdomains. RESULTS There were no difficulties to translate the original version into Spanish. There was good acceptability demonstrated by minimal missing data and floor/ceiling effects. Test-retest reliability for the overall score, and the subscales scores was 0.949 (0.854-0.944). Internal consistency analysis by Cronbach's a was 0.950 (0.851-0.900). CONCLUSIONS This small scale study provided preliminary evidence for the acceptability and reliability of the Spanish version of the SAQOL-39. Further testing in larger samples is needed to evaluate the validity of the scale, its sensitivity to change and to confirm its reliability.
Perspectives: Human osteoblastic cells: A potential tool to assess the etiology of pathologic bone formation

NWSTEAL BONE FORMATION is a complex process depenE dent on the proliferation of osteoprogenitor cells in the marrow stroma, the differentiation of preosteoblasts into mature osteoblasts, and the functional activity of differentiated osteoblasts. Each of these steps is essential for the initiation of osteogenesis and the deposition of new bone matrix in the remodeling unit. Histomorphometric studies indicate that bone formation is mainly regulated at two key levels along the osteoblastic differentiating pathway, the proliferation of osteoprogenitor cells and the activity of mature osteoblasts. and that the rate of bone formation at the tissue level is more dependent on the number of osteoblasts than on their activity. ('-3' However, the cellular mechanisms involved in the abnormal bone formation in pathologic states remain largely unknown. One of the tools that may allow us to assess the mechanistic causes of pathologic bone formation in metabolic bone diseases is the use of human bone cell cultures. The recent development of studies comparing human osteoblastic cell behavior in vitro and bone formation suggests that cultures of osteoblasts may be an interesting approach to the study of genetic and acquired abnormalities of bone formation. This paper reviews the interests and limits of this approach and the perspectives for future research on the etiology and treatment of pathologic bone formation.
Effect of pulse‐burst electromagnetic field stimulation on osteoblast cell activities

Electric stimulation has been used successfully to treat a wide range of bone disorders. However, the mechanism by which the electric fields can influence the bone cells behavior remains poorly understood. The purpose of this research was to assess the possible mechanism of the stimulatory effect of pulsed electromagnetic field (PEMF) on bone cells. A PEMF with a frequency of 15 Hz (1 G [0.1 mT]; electric field strength 2 mV/cm) were applied to neonatal mouse calvarial bone cell cultures for 14 days. The temporal effects of PEMF on the osteoblasts were evaluated by the status of proliferation, differentiation, mineralization, and gene expression on the 3rd, 5th, 7th, and 14th days of culture. Our results demonstrated that PEMF stimulation significantly increased the osteoblasts' proliferation by 34.0, 11.5, and 13.3% over the control group after 3, 5, and 7 days' culture. Although the alkaline phosphatase (ALP) staining and the mineralization nodules formation did not change, the ALP activity of the bone cells decreased significantly after PEMF stimulation. Under the PEMF stimulation, there was no effect on the extracellular matrix synthesis, while the osteoprotegerin (OPG) mRNA expression was up regulated and the receptor activator of NF‐κB ligand (RANKL) mRNA expression were down regulated, compared to the control. In conclusion, the treatment by PEMF of osteoblasts may accelerate cellular proliferation, but did not affect the cellular differentiation. The effect of PEMF stimulation on the bone tissue formation was most likely associated with the increase in the number of cells, but not with the enhancement of the osteoblasts' differentiation.

Explanation, prediction, and causality: Three sides of the same coin?

In this essay we make four interrelated points. First, we reiterate previous arguments (Kleinberg et al 2015) that forecasting problems are more common in social science than is often appreciated. From this observation it follows that social scientists should care about predictive accuracy in addition to unbiased or consistent estimation of causal relationships. Second, we argue that social scientists should be interested in prediction even if they have no interest in forecasting per se. Whether they do so explicitly or not, that is, causal claims necessarily make predictions; thus it is both fair and arguably useful to hold them accountable for the accuracy of the predictions they make. Third, we argue that prediction, used in either of the above two senses, is a useful metric for quantifying progress. Important differences between social science explanations and machine learning algorithms notwithstanding, social scientists can still learn from approaches like the Common Task Framework (CTF) which have successfully driven progress in certain fields of AI over the past 30 years (Donoho, 2015). Finally, we anticipate that as the predictive performance of forecasting models and explanations alike receives more attention, it will become clear that it is subject to some upper limit which lies well below deterministic accuracy for many applications of interest (Martin et al 2016). Characterizing the properties of complex social systems that lead to higher or lower predictive limits therefore poses an interesting challenge for computational social science.
Office of Rare Diseases Neuropathologic Criteria for Corticobasal Degeneration

A working group supported by the Office of Rare Diseases of the National Institutes of Health formulated neuropathologic criteria for corticobasal degeneration (CBD) that were subsequently validated by an independent group of neuropathologists. The criteria do not require a specific clinical phenotype, since CBD can have diverse clinical presentations, such as progressive asymmetrical rigidity and apraxia, progressive aphasia, or frontal lobe dementia. Cortical atrophy, ballooned neurons, and degeneration of the substantia nigra have been emphasized in previous descriptions and are present in CBD, but the present criteria emphasize tau-immunoreactive lesions in neurons, glia, and cell processes in the neuropathologic diagnosis of CBD. The minimal pathologic features for CBD are cortical and striatal tau-positive neuronal and glial lesions, especially astrocytic plaques and thread-like lesions in both white matter and gray matter, along with neuronal loss in focal cortical regions and in the substantia nigra. The methods required to make this diagnosis include histologic stains to assess neuronal loss, spongiosis and ballooned neurons, and a method to detect tau-positive neuronal and glial lesions. Use of either the Gallyas silver staining method or immunostains with sensitive tau antibodies is acceptable. In cases where ballooned neurons are sparse or difficult to detect, immunostaining for phospho-neurofilament or α-B-crystallin may prove helpful. Methods to assess Alzheimer-type pathology and Lewy body pathology are necessary to rule out other causes of dementia and Parkinsonism. Using these criteria provides good differentiation of CBD from other tauopathies, except frontotemporal dementia and Parkinsonism linked to chromosome 17, where additional clinical or molecular genetic information is required to make an accurate diagnosis.
Metabolic Engineering of Clostridium acetobutylicum ATCC 824 for Isopropanol-Butanol-Ethanol Fermentation

ABSTRACT Clostridium acetobutylicum naturally produces acetone as well as butanol and ethanol. Since acetone cannot be used as a biofuel, its production needs to be minimized or suppressed by cell or bioreactor engineering. Thus, there have been attempts to disrupt or inactivate the acetone formation pathway. Here we present another approach, namely, converting acetone to isopropanol by metabolic engineering. Since isopropanol can be used as a fuel additive, the mixture of isopropanol, butanol, and ethanol (IBE) produced by engineered C. acetobutylicum can be directly used as a biofuel. IBE production is achieved by the expression of a primary/secondary alcohol dehydrogenase gene from Clostridium beijerinckii NRRL B-593 (i.e., adh B-593) in C. acetobutylicum ATCC 824. To increase the total alcohol titer, a synthetic acetone operon (act operon; adc-ctfA-ctfB) was constructed and expressed to increase the flux toward isopropanol formation. When this engineering strategy was applied to the PJC4BK strain lacking in the buk gene (encoding butyrate kinase), a significantly higher titer and yield of IBE could be achieved. The resulting PJC4BK(pIPA3-Cm2) strain produced 20.4 g/liter of total alcohol. Fermentation could be prolonged by in situ removal of solvents by gas stripping, and 35.6 g/liter of the IBE mixture could be produced in 45 h.
The Merging of Alcohol and Drug Treatment: A Policy Review

Alcohol and drug treatment have separate histories in the United States. The large public treatment systems were established as separate institutions in the early 1970s and have developed separate research traditions and treatment programs. However, as a response to current treatment financing policy and epidemiologic descriptions of combined alcohol and other drug use in the population, the two treatment systems are merging at the state and local levels. This large structural change is taking place without the development and evaluation of treatment methods for combined problems and without discussion of overall health service or policy implications. This paper describes the changes occurring, examines the literature for its contributions in providing direction, and presents treatment method and policy issues which need to be part of the overall discourse.
An approach to treatment resistance in schizophrenia

Currently, patients with schizophrenia are usually considered refractory to treatment if they continue to be floridly symptomatic despite receiving treatment with conventional antipsychotic agents. Attempts to improve their response by increasing the dosage, adding supplementary drugs, or switching to agents of another class have not been very successful, and may increase side-effects. Clozapine can be effective, but it is a difficult drug to administer and has therefore been reserved for patients who are doing poorly. With the recent introduction of newer, safer antipsychotic agents, however, even patients who have milder refractory symptoms that persist after treatment with conventional antipsychotics can now be treated.
Extracellular matrix proteins characterize human tumor cell lines

Extracellular matrix proteins synthesized and secreted by adherent human tumor cell lines were analyzed using metabolic labelling with glycine and proline in the presence of ascorbate, polypeptide analysis by polyacrylmide gel electrophoresis, affinity chromatography, collagenase digestion, and immunofluorescence staining. The results showed a characteristic pattern of matrix proteins for each tumor cell type. Tumor cell lines of mesenchymal origin produced mostly interstitial types (I and III) of collagen and fibronectin. Carcinoma cell lines secreted only basement membrane proteins, type IV collagen, laminin and fibronectin, but not interstitial collagens. A melanoma and a rhabdomyosarcoma cell line produced type V of procollagen that has not previously been described in cell culture. Neuroblastoma cells were shown to be phenotypically heterogeneous also with respect to matrix protein production. We propose that the analysis of extracellular matrix proteins may serve as an adjunct in the classification of human tumors.
Klotho suppresses renal tubulo‐interstitial fibrosis by controlling basic fibroblast growth factor‐2 signalling

Increased basic fibroblast growth factor‐2 (FGF2) and reduced Klotho have both been reported to be closely associated with renal fibrosis. However, the relationship between Klotho and FGF2 remains unclear. We demonstrate that FGF2 induced tubulo‐epithelial plasticity in cultured HK‐2 cells, accompanied by a reduction in Klotho expression, whereas recombinant Klotho protein could inhibit the action of FGF2. The FGF2 effects required extracellular signal‐regulated protein kinase 1/2 activation, which was suppressed by Klotho. Moreover, Klotho also restrained FGF2‐induced fibroblast proliferation and activation. The inhibitory effect of Klotho on the activity of FGF2 was likely due to its potent ability to compete with FGF2 binding to FGF receptor 1. Unilateral ureteral obstruction (UUO)‐induced renal fibrosis was associated with an increase in FGF2 and a reduction in Klotho expression in wild‐type mice, whereas FGF2–/– mice largely preserved Klotho expression and developed only mild renal fibrosis after obstructive injury. Furthermore, administration of Klotho protein in UUO mice significantly reduced renal fibrosis, concomitant with a marked suppression of FGF2 production and signalling. These studies demonstrate a feedback loop between Klotho depletion and FGF2 activation in renal fibrosis. Our results also suggest that Klotho treatment reduces renal fibrosis, at least in part, by inhibiting FGF2 signalling. Copyright © 2014 Pathological Society of Great Britain and Ireland.

Glucosamine Supplementation During In Vitro Maturation Inhibits Subsequent Embryo Development: Possible Role of the Hexosamine Pathway as a Regulator of Developmental Competence1

Abstract Glucose concentration during cumulus-oocyte complex (COC) maturation influences several functions, including progression of oocyte meiosis, oocyte developmental competence, and cumulus mucification. Glucosamine (GlcN) is an alternative hexose substrate, specifically metabolized through the hexosamine biosynthesis pathway, which provides the intermediates for extracellular matrix formation during cumulus cell mucification. The aim of this study was to determine the influence of GlcN on meiotic progression and oocyte developmental competence following in vitro maturation (IVM). The presence of GlcN during bovine IVM did not affect the completion of nuclear maturation and early cleavage, but severely perturbed blastocyst development. This effect was subsequently shown to be dose-dependent and was also observed for porcine oocytes matured in vitro. Hexosamine biosynthesis upregulation using GlcN supplementation is well known to increase O-linked glycosylation of many intracellular signaling molecules, the best-characterized being the phosphoinositol-3-kinase (PI3K) signaling pathway. We observed extensive O-linked glycosylation in bovine cumulus cells, but not oocytes, following IVM in either the presence or the absence of GlcN. Inhibition of O-linked glycosylation significantly reversed the effect of GlcN-induced reduction in developmental competence, but inhibition of PI3K signaling had no effect. Our data are the first to link hexosamine biosynthesis, involved in cumulus cell mucification, to oocyte developmental competence during in vitro maturation.
Inverse Fault Detection and Diagnosis Problem in Discrete Dynamic Systems

This paper investigates an inverse fault detection and diagnosis problem in discrete dynamic systems. The problem is how to adjust the system parameters according to observation value of inputs and outputs so that the system is concordant. First we formulate the problem as a least square problem with interval coefficients. Then two algorithms for this problem are presented. The first algorithm based on the expected value of observation value of inputs and outputs. We are only required to solve a classical least square problem in this algorithm and the algorithm is robust. The second algorithm by using linear programming approach can deal with large scale systems and suit for on line adjustment.
A dynamic global equilibrium in carnivoran diversification over 20 million years

The ecological and evolutionary processes leading to present-day biological diversity can be inferred by reconstructing the phylogeny of living organisms, and then modelling potential processes that could have produced this genealogy. A more direct approach is to estimate past processes from the fossil record. The Carnivora (Mammalia) has both substantial extant species richness and a rich fossil record. We compiled species-level data for over 10 000 fossil occurrences of nearly 1400 carnivoran species. Using this compilation, we estimated extinction, speciation and net diversification for carnivorans through the Neogene (22–2 Ma), while simultaneously modelling sampling probability. Our analyses show that caniforms (dogs, bears and relatives) have higher speciation and extinction rates than feliforms (cats, hyenas and relatives), but lower rates of net diversification. We also find that despite continual species turnover, net carnivoran diversification through the Neogene is surprisingly stable, suggesting a saturated adaptive zone, despite restructuring of the physical environment. This result is strikingly different from analyses of carnivoran diversification estimated from extant species alone. Two intervals show elevated diversification rates (13–12 Ma and 4–3 Ma), although the precise causal factors behind the two peaks in carnivoran diversification remain open questions.
Enhanced root exudation stimulates soil nitrogen transformations in a subalpine coniferous forest under experimental warming

Despite the perceived importance of exudation to forest ecosystem function, few studies have attempted to examine the effects of elevated temperature and nutrition availability on the rates of root exudation and associated microbial processes. In this study, we performed an experiment in which in situ exudates were collected from Picea asperata seedlings that were transplanted in disturbed soils exposed to two levels of temperature (ambient temperature and infrared heater warming) and two nitrogen levels (unfertilized and 25 g N m−2 a−1). Here, we show that the trees exposed to an elevated temperature increased their exudation rates I (μg C g−1 root biomass h−1), II (μg C cm−1 root length h−1) and III (μg C cm−2 root area h−1) in the unfertilized plots. The altered morphological and physiological traits of the roots exposed to experimental warming could be responsible for this variation in root exudation. Moreover, these increases in root‐derived C were positively correlated with the microbial release of extracellular enzymes involved in the breakdown of organic N (R2 = 0.790; P = 0.038), which was coupled with stimulated microbial activity and accelerated N transformations in the unfertilized soils. In contrast, the trees exposed to both experimental warming and N fertilization did not show increased exudation rates or soil enzyme activity, indicating that the stimulatory effects of experimental warming on root exudation depend on soil fertility. Collectively, our results provide preliminary evidence that an increase in the release of root exudates into the soil may be an important physiological adjustment by which the sustained growth responses of plants to experimental warming may be maintained via enhanced soil microbial activity and soil N transformation. Accordingly, the underlying mechanisms by which plant root‐microbe interactions influence soil organic matter decomposition and N cycling should be incorporated into climate‐carbon cycle models to determine reliable estimates of long‐term C storage in forests.
