History matters: Heterotrophic microbial community structure and function adapt to multiple stressors

Ecosystem functions in streams (e.g., microbially mediated leaf litter breakdown) are threatened globally by the predicted agricultural intensification and its expansion into pristine areas, which is associated with increasing use of fertilizers and pesticides. However, the ecological consequences may depend on the disturbance history of microbial communities. To test this, we assessed the effects of fungicides and nutrients (four levels each) on the structural and functional resilience of leaf‐associated microbial communities with differing disturbance histories (pristine vs. previously disturbed) in a 2 × 4 × 4‐factorial design (n = 6) over 21 days. Microbial leaf breakdown was assessed as a functional variable, whereas structural changes were characterized by the fungal community composition, species richness, biomass, and other factors. Leaf breakdown by the pristine microbial community was reduced by up to 30% upon fungicide exposure compared with controls, whereas the previously disturbed microbial community increased leaf breakdown by up to 85%. This significant difference in the functional response increased in magnitude with increasing nutrient concentrations. A pollution‐induced community tolerance in the previously disturbed microbial community, which was dominated by a few species with high breakdown efficacies, may explain the maintained function under stress. Hence, the global pressure on pristine ecosystems by agricultural expansion is expected to cause a modification in the structure and function of heterotrophic microbial communities, with microbially mediated leaf litter breakdown likely becoming more stable over time as a consequence of fungal community adaptions.
Genetic diversity of Blastocystis hominis sensu lato isolated from humans in Poland

INTRODUCTION AND OBJECTIVES Blastocystis hominis s. l. is one of the most commonly detected protozoa in the human large intestine. The aim of the study was to determine the genetic subtypes of Blastocystis hominis s. l. occurring in humans in Poland. MATERIALS AND METHODS Stool samples from patients diagnosed in the Laboratory of the Department of Parasitology, National Institute of Public Health – National Institute of Hygiene (NIZP-PZH) and in the Parasitology Laboratory of the Hospital for Infectious Diseases in Warsaw were examined. Blastocystis subtypes were assayed based on the fragment of small-subunit ribosomal RNA gene sequences (SSU rDNA). RESULTS The examined isolates were classified into five Blastocystis subtypes (STs), fifteen of which belonged to ST3, three to ST1, two to ST2, two to ST6, and one isolate belonged to ST7. In three cases the subtype of isolate was not identified. DISCUSSION AND CONCLUSIONS In Poland, the subtypes ST1, ST2, ST3, ST4, ST6 and ST7 have been reported in humans so far. The ST6 and ST7 subtypes are rarely detected in humans in Europe. In Poland, the ST6 subtype was previously described in chickens. On the basis of the studies, it was found that Blastocystis isolated from humans in Warsaw show high genetic diversity. In order to determine the possible pathogenic potential of individual Blastocystis subtypes, special epidemiological studies are required.
Simultaneous mapping of metabolites and individual macromolecular components via ultra‐short acquisition delay 1H MRSI in the brain at 7T

Short‐echo‐time proton MR spectra at 7T feature nine to 10 distinct macromolecule (MM) resonances that overlap with the signals of metabolites. Typically, a metabolite‐nulled in vivo MM spectrum is included in the quantification`s prior knowledge to provide unbiased metabolite quantification. However, this MM model may fail if MMs are pathologically altered. In addition, information about the individual MM peaks is lost. In this study, we aimed to create an improved MM model by parameterization of the in vivo MM spectrum into individual components, and to use this new model to quantify free induction decay MR spectroscopic imaging (FID‐MRSI) data.
Clinical Significance of Atypical Glandular Cells in Conventional Pap Smears in a Large, High-Risk U.S. West Coast Minority Population

OBJECTIVE To determine the incidence of clinically significant lesions on subsequent histologic follow-up in high-risk, predominantly minority patients with atypical glandular cells (AGC). STUDY DESIGN A retrospective study was done on conventional Pap smears diagnosed as AGC of endocervical origin (AGC-EC), AGC of endometrial origin (AGC-EM) and AGC not otherwise specified (AGC-NOS) between January 1, 2003, and December 31, 2005. Histologic diagnoses were correlated with cytologic diagnoses. RESULT Confirmed AGC cases were divided into 4 categories: 187 AGC-NOS, 169 AGC-EC, 68 AGC and atypical squamous cells of undetermined significance (ASCUS) and 36 AGC-EM. A total of 105 patients (22.8%) had significant precancerous (cervical intraepithelial neoplasia [CIN] 2/3, adenocarcinoma in situ [AIS]) or malignant (carcinoma) histologic outcomes. CIN 2/3 was the most common significant histologic outcome in women with AGC and ASCUS and patients <35 years with AGC. Endometrial neoplasia was the most common significant outcome in women with AGC-NOS and AGC-EM Pap results and in AGC patients > or =35. In women with AGC-EC Pap results, glandular cervical neoplasia occurred in 8.3% and CIN 2/3 in 5.9% offollow-up biopsies. CONCLUSION AGC subtype and age significantly affect the probability of precancerous and malignant follow-up findings and anatomic site of neoplastic lesions. Access to newer screening technologies such as high-risk HPVDNA testing and liquid-based cytology will likely benefit such high-risk populations.
Enhanced Resolution of Microwave Sounder Imagery through Fusion with Infrared Sensor Data

The images acquired by microwave sensors are blurry and have low resolution. On the other hand, the images obtained using infrared/visible sensors are often of higher resolution. In this paper, we develop a data fusion methodology and apply it to enhance the resolution of a microwave image using the data from a collocated infrared/visible sensor. Such an approach takes advantage of the spatial resolution of the infrared instrument and the sensing accuracy of the microwave instrument. The model leverages sparsity in signals and is based on current research in sparse optimization and compressed sensing. We tested our method using a precipitation scene captured with the Advanced Microwave Sounding Unit (AMSU-B) microwave instrument and the Advanced Very High Resolution Radiometer (AVHRR) infrared instrument and compared the results to simultaneous radar observations. We show that the data fusion product is better than the original AMSU-B and AVHRR observations across all statistical indicators.
Risk factors and coping strategies of severe community-acquired pneumonia in chemotherapy induction period of acute leukemia

The risk factors and coping strategies of severe community-acquired pneumonia (SCAP) in chemotherapy induction period of acute leukemia were investigated. Eighty-six patients with CAP in chemotherapy induction period of acute leukemia in Dezhou Hospital from March 2014 to February 2017 were selected and divided into observation group (SCAP group, n=45) and control group (non-SCAP group, n=41) according to the acute physiology and chronic health evolution II (APACHE II) score. The blood, sputum, nasopharyngeal secretion and pleural effusion samples were collected from patients in both groups, and the samples were detected for pathogens, followed by the analysis of relevant factors. The dynamic changes in the sequential organ failure assessment (SOFA) score, procalcitonin (PCT), D-dimer (D-D) and C-reactive protein (CRP) levels in patients were observed before and after the corresponding treatment strategies were taken. The total distribution ratio of pathogens from high to low in the two groups was as follows: bacterium, virus, fungus, mycoplasma and chlamydia trachomatis; there was no significant difference between the two groups (P>0.05). Logistic regression analysis showed that the repeated infection (OR=3.315, P=0.005), multi-resistant bacterial infection (OR=1.915, P=0.008) and D-D (OR=1.936, P=0.009) were independent risk factors for SCAP (P<0.05). After different coping strategies were taken, the SOFA score, PCT, D-D and CRP levels in the two groups were significantly decreased, and they were obviously higher in observation group than those in control group (P<0.05). Repeated infection, D-D level and multi-resistant bacterial infection are the risk factors affecting the SCAP in chemotherapy induction period of acute leukemia. The coping strategies can effectively relieve the patient's condition, reduce the severity of disease and improve the survival rate of patients.
Wikipedia as a source of monolingual and multilingual information about the Spanish heritage

The aim of the study was to analyze the online encyclopaedia Wikipedia as a tool for the dissemination of monolingual and multilingual information about the Spanish heritage. The sample consists of catalogued buildings and sites of cultural interest in a Spanish region. For that purpose, we examined to what extent articles about the buildings and sites are represented in Wikipedia that is, what kind of information is dedicated to each of them. Three different types of search in the encyclopaedia (browsing, lists and internal search engine) were performed for several months. In addition, we established to what extent Wikipedia includes multilingual information regarding the sample, that is, the number of languages in which the information is expressed, as well as articles translated into languages other than Spanish. The results show that only 21.73% of the buildings and sites that constitute the final sample have a separate article in Wikipedia, of which only 20.85% are in several languages, and 50.00% are properly described as translations. This leads us to conclude that, given the collaborative nature of this tool and in view of the cultural and economic importance of historical and cultural heritage, institutions should be responsible for promoting the multilingual dissemination of this type of information.
Material-based strategies to engineer fibronectin matrices for regenerative medicine

Engineering biomaterials for regenerative medicine involves a myriad of aspects to be considered for the successful design, interaction with cells and integration with living tissues (i.e. pore size, mechanical properties, degradation rate, biological activity). Among different technologies used to functionalise synthetic biomaterials and promote cell adhesion, cell growth and cell differentiation, this review focuses on strategies to organise extracellular matrix (ECM) proteins in a biomimetic way, as cells do in natural tissues in vivo (the ECM is a mesh of proteins that surrounds cells, and therefore, constitutes the scaffolding of a tissue), but using functional materials instead of living cells. The authors critically review material-based strategies to organise fibronectin (FN), a core component in the ECM of many tissues, and engineer microenvironments that recapitulate the structure and properties of the ECM. Material-driven organisation of FN in analogy with their natural cell-mediated assembly is a powerful route to engineer the network structure and biological activity of FN fibrillar matrices, seeking to develop biomimetic scaffolds for regenerative medicine. Here, the authors discuss different routes to promote the cell-free formation of FN fibrils as well as the biological impact of these engineered cellular microenvironments.
Dewatering and Treatment of Septage Using Vertical Flow Constructed Wetlands

The vertical flow constructed wetland (VFCW) has become an attractive decentralised technology for septage treatment. One of the main purposes of the septage treatment is to reduce the volume of raw septage through dewatering, where the solids content is retained in the wetland bed and the water content is released. The retention of solids forms a layer of sludge deposit at the wetland surface, and the drained water, the so-called leachate, typically contains a lower solids content. This article reports the performance of dewatering and filtration of a pilot-scale VFCW designed for septage treatment. A comparison between two feeding strategies, hydraulic loading rate (HLR) and solids loading rate (SLR), is presented. The dewatering efficiency through drainage was found to be dependent on the solids load. The removal of total solids (TS) and chemical oxygen demand (COD) were excellent as the quality of leachate showed that more than 90% of TS and COD were retained in the system. This study reveals that the feeding based on SLR delivered a more sustainable performance for dewatering and solids removal. The build-up of sludge deposit significantly deteriorated the dewatering efficiency through drainage, but it tended to improve the filtration capacity.
Application of Liquid-Based Preparation to Fine Needle Aspiration Cytology in Breast Cancer

OBJECTIVE To examine the performance of liquid-based cytology (LBC) in breast cytology to confirm the diagnosis of carcinoma. STUDY DESIGN Using cell clusters directly scratched from surgically removed tumor masses, we examined the immunocytochemistry, molecular biology and cytomorphology of the specimens. RESULTS LBC was very useful for gene analysis and evaluating the immunocytochemistry. The cytologic features of LBC were slightly different from those ofa conventional aspiration cytology smear. CONCLUSION LBC is a promising method for improving the standardization ofpreparations in breast cytology, although care should be taken to account for its characteristic cytologic features. The quantitative analysis of HER-2 mRNA correlated with the results of immunohistochemistry.
Treatment effect with paliperidone palmitate compared with oral antipsychotics in patients with recent‐onset versus more chronic schizophrenia and a history of criminal justice system involvement

Long‐acting injectable antipsychotics (APs) are not well studied in recent‐onset schizophrenia. This exploratory analysis of a study designed to reflect real‐world schizophrenia, as defined by patients, interventions and outcomes, compared relative treatment effect between once‐monthly paliperidone palmitate (PP) and daily oral APs in patients with recent‐onset or chronic illness
CB1R-Mediated Activation of Caspase-3 Causes Epigenetic and Neurobehavioral Abnormalities in Postnatal Ethanol-Exposed Mice

Alcohol exposure can affect brain development, leading to long-lasting behavioral problems, including cognitive impairment, which together is defined as fetal alcohol spectrum disorder (FASD). However, the fundamental mechanisms through which this occurs are largely unknown. In this study, we report that the exposure of postnatal day 7 (P7) mice to ethanol activates caspase-3 via cannabinoid receptor type-1 (CB1R) in neonatal mice and causes a reduction in methylated DNA binding protein (MeCP2) levels. The developmental expression of MeCP2 in mice is closely correlated with synaptogenesis and neuronal maturation. It was shown that ethanol treatment of P7 mice enhanced Mecp2 mRNA levels but reduced protein levels. The genetic deletion of CB1R prevented, and administration of a CB1R antagonist before ethanol treatment of P7 mice inhibited caspase-3 activation. Additionally, it reversed the loss of MeCP2 protein, cAMP response element binding protein (CREB) activation, and activity-regulated cytoskeleton-associated protein (Arc) expression. The inhibition of caspase-3 activity prior to ethanol administration prevented ethanol-induced loss of MeCP2, CREB activation, epigenetic regulation of Arc expression, long-term potentiation (LTP), spatial memory deficits and activity-dependent impairment of several signaling molecules, including MeCP2, in adult mice. Collectively, these results reveal that the ethanol-induced CB1R-mediated activation of caspase-3 degrades the MeCP2 protein in the P7 mouse brain and causes long-lasting neurobehavioral deficits in adult mice. This CB1R-mediated instability of MeCP2 during active synaptic maturation may disrupt synaptic circuit maturation and lead to neurobehavioral abnormalities, as observed in this animal model of FASD.
Cytology in the follow-up of cervical cancer.

OBJECTIVE To determine the value of cytology in the follow-up of cervical cancer. STUDY DESIGN The study group consisted of 230 patients with invasive cervical carcinoma who were followed for one to seven years. Forty-four patients developed recurrences or metastases. During this period, cytologic investigations involved 795 exfoliative smears from the cervix or vaginal vault, 10 fine needle aspirates and 5 fluids. RESULTS Thirty-three patients had positive or inconclusive cervical or vault smears that were histologically proven to be recurrences, and the other 11 patients had clinically obvious recurrences that were not smeared. Cytology first alerted the clinicians to recurrence in eight patients. Of 25 cervical or vault smears reported as malignant, 24 (96%) were histologically confirmed, and 1 showed radiation change on biopsy. In all 22 cases of smears reported as inconclusive, a biopsy followed, and in 9 (41%) of these, recurrence was demonstrated histologically. Inability to distinguish radiation change from recurrent malignancy was the chief cause of inconclusive smears. Five fluids and seven fine needle aspirates were diagnosed as malignant, saving patients an invasive diagnostic procedure. CONCLUSION Cytology is a useful, cost-effective, noninvasive and accurate investigation in the follow-up of cervical cancer.
Electron-microscopic study of iris nerves and muscles in diabetes.

The ultrastructure of the iris muscles and innervating nerves in patients with diabetes mellitus and approximately age-matched controls was examined by electron-microscopy. The specimens were obtained during cataract surgery. There were definite histopathological alterations at the nerve terminal innervating the dilator muscle, e.g. the presence of mitochondrial abnormalities, dense bodies and lamellar structures. No change was noted at the nerve terminal to the sphincter muscle. Moderate involvement of the muscle, especially at the sphincter, was observed in the specimens of diabetics. The control specimens had no change at the nerve terminals, while moderate change was observed at the sphincter muscle. Therefore, the change in the sphincter seen in the specimens of diabetics seemed to be mainly the result of the aging process, though the existence of early sympathetic neuropathy was confirmed.
Ethnic Patterns of Cytologic Abnormalities in Cervical Smears in Suriname, a High-Risk Area for Cervical Cancer

OBJECTIVE To determine the prevalence of cytologic abnormalities in cervical smears from women attending the first organized screening program in Suriname and to compare the prevalences in 4 Surinamese ethnicities with different cervical carcinoma incidences. STUDY DESIGN Cervical scrapes were taken from women with 4 different ethnicities: Maroons, Amerindians, Javanese and Hindustani. Papanicolaou staining and cytologic screening were performed on 807 cervical smears. RESULTS Cervical cytologic abnormalities were seen in 13.4%, of which 8.1% (62 of 764) had atypical changes, 2.6% (20 of 764) had mild and 2.6% (20 of 764) had moderate and severe dysplasia/carcinoma in situ (CIS). The cytologic abnormalities varied between the ethnicities: 42.1% (83 of 197) in the Maroons and 2.3% (4 of 176), 5.0% (9 of 183) and 3.0% (6 of 208) in the Javanese, Amerindians, and Hindustani, respectively. CONCLUSION The high prevalence of moderate and severe dysplasia/CIS in all ethnicities correlates with the high cervical carcinoma incidence in Suriname. A significantly higher prevalence of mild abnormalities in the Maroons was observed; it did not reflect the relatively low cervical cancer incidence in this ethnicity. However, this can be explained by the possibility that these women have a different sexual lifestyle, leading to a higher prevalence of
Beware of the origin of numbers: Standard scoring of the SF‐12 and SF‐36 summary measures distorts measurement and score interpretations

The 12-item Short Form Health Survey (SF-12) is a generic health rating scale developed to reproduce the Physical and Mental Component Summary scores (PCS and MCS, respectively) of a longer survey, the SF-36. The standard PCS/MCS scoring algorithm has been criticized because its expected dimensionality often lacks empirical support, scoring is based on the assumption that physical and mental health are uncorrelated, and because scores on physical health items influence MCS scores, and vice versa. In this paper, we review the standard PCS/MCS scoring algorithm for the SF-12 and consider alternative scoring procedures: the RAND-12 Health Status Inventory (HSI) and raw sum scores. We corroborate that the SF-12 reproduces SF-36 scores but also inherits its problems. In simulations, good physical health scores reduce mental health scores, and vice versa. This may explain results of clinical studies in which, for example, poor physical health scores result in good MCS scores despite compromised mental health. When applied to empirical data from people with Parkinson's disease (PD) and stroke, standard SF-12 scores suggest a weak correlation between physical and mental health (rs .16), whereas RAND-12 HSI and raw sum scores show a much stronger correlation (rs .67-.68). Furthermore, standard PCS scores yield a different statistical conclusion regarding the association between physical health and age than do RAND-12 HSI and raw sum scores. We recommend that the standard SF-12 scoring algorithm be abandoned in favor of alternatives that provide more valid representations of physical and mental health, of which raw sum scores appear the simplest.
Surface Roughness Characterization of ZnO: TiO2-Organic Blended Solar Cells Layers by Atomic Force Microscopy and Fractal Analysis

The objective of this work is to quantitatively characterize the 3D complexity of ZnO:TiO2-organic blended solar cells layers by atomic force microscopy and fractal analysis. ZnO:TiO2-organic blended solar cells layers were investigated by AFM in tapping-mode in air, on square areas of 25 μm2. A detailed methodology for ZnO:TiO2-organic blended solar cells layers surface fractal characterization, which may be applied for AFM data, is presented. Detailed surface characterization of the surface topography was obtained using statistical parameters, according with ISO 25178-2: 2012. The fractal dimensions Df values (all with average ± standard deviation), obtained with morphological envelopes method, for: blend D1 (P3HT:PCBM:ZnO:TiO2 blend with ratio 1:0.35:0.175:0.175 mg in 1 ml of Chlorobenzene) is Df = 2.55 ± 0.01; and for blend D2 (P3HT:PCBM:ZnO:TiO2 blend with ratio 1:0.55:0.075:0.075 mg in 1 ml of Chlorobenzene) is Df = 2.45 ± 0.01. Denoting the ratios in 1 ml of Chlorobenzene with D1 and D2 articles. The 3D surface roughness of samples revealed a fractal structure at nanometer scale. Fractal and AFM analysis may assist manufacturers in developing ZnO:TiO2-organic blended solar cells layers with better surface characteristics and provides different yet complementary information to that offered by traditional surface statistical parameters.
