Unexpected reproductive traits of Grateloupia turuturu revealed by its resistance to bleach-based biosecurity protocols
Authors: Capistrant-Fossa Kyle , Brawley Susan H. 
Published: March 2019

Abstract
A non-indigenous alga, Grateloupia turuturu (Halymeniales, Rhodophyta), was discovered in the Damariscotta Estuary (Maine, USA) in 2017, over 200 km north of its last reported location. Because of the presence of coastal facilities (aquaculture, marine laboratories) among potential vectors, we evaluated a mandated biosecurity protocol, namely, seawater treated with bleach at 50 ppm (50 mg l−1) free chlorine for ≥2 h and measured using test strips, for lethality against G. turuturu and several native algae. We report unexpected resilience to bleach-treatment (Mastocarpus > Grateloupia > Palmaria). Holdfasts of G. turuturu and Mastocarpus stellatus survived 50 and 1000 ppm free chlorine, respectively. Cystocarps on cultured blades of G. turuturu were particularly resistant to bleach-treatment; they produced outgrowths on fragmenting blades that became fertile tetrasporophytes in culture, suggesting reproductive adaptations of cystocarps to stressful conditions that may have broader evolutionary significance. Juvenile, microscopic crusts of G. turuturu were also bleach-resistant if covered by diatoms, and developed upright axes. Free chlorine test strips were inaccurate in seawater, and their use could increase the risk of failed biosecurity as a vector for invasion. Because chlorination at economic and environmentally safe levels is insufficient, we recommend a combination of treatments for comprehensive biosecurity.
Philosophie in ihrer (und gegen ihre) Zeit
Authors: Saar Martin 
Published: March 2019

AbstractIt is not evident in what sense philosophy relates to its own time and present. From the history of philosophical thought, several models have been suggested, ranging from a strong reliance on tradition to the wholesale rejection of the present and demand for a ‘philosophy of the future,’ from the suspicion that philosophy is nothing but one ideology among others to the demand that philosophy should engage in the struggles and conflicts of its time in order to prepare for a better future. The essay presents an assessment and problematization of these approaches and argues for a point of view that starts from philosophy’s precarious, ambivalent and contingent relation to its time and contemporaneity. Neither wholly independent of nor entirely subjected to its own time, philosophy can inhabit a shifting position from which critique and resistance are possible even if not ultimately guaranteed.
Dogmatischer Dogmatismusvorwurf
Authors: Freyenhagen Fabian 
Published: March 2019

Abstract
Does theorising always presuppose a programme of justification? Does the Critical Theory of Adorno and Horkheimer do so? Do they claim it does? The answer should be a resounding ‘no’ to all three questions. In regard to the second and third question, I have sketched an argument to that effect in an earlier paper in this journal. In this paper, I offer a rejoinder to the critical reply offered by Stefan Müller-Doohm und Roman Yos on behalf of the Habermasian mainstream in Frankfurt School Critical Theory. This rejoinder depends on giving a negative answer also to the first question. In rejecting the Habermasian idea of a programme of justification, I stand accused of dogmatism and, consequently, decisionism (for how else than by an arbitrary decision can one choose among dogmas?). I show that this accusation itself betrays a certain dogmatism – insofar as it accepts that such a programme of justification is undeniably possible and required, without consideration of evidence or arguments to the contrary. Self-reflective and critical theorising about society can, indeed must, take other forms.

Published: March 2019

Abstract
The study shows the basic interaction between different optical sources and optical detectors for high-speed optical communication networks. Optical sources that are namely continuous wave (CW) laser, laser rate equations as well as the vertical cavity surface emitting laser (VCSEL). The utilized optical modulators are indicated as Mach Zehnder modulator (MZM) as well as the Electro-absorption modulator (EAM). The data rate available 40 Gb/s for propagation length ranges from 10 km to 50 km. It is observed that the interaction between CW laser/MZM or CW laser/EAM has presented better performance than other combinations. In order to measure the system performances, many interesting parameters have been investigated. These can be including the electrical received power, highest signal quality factor, Optical signal per noise ratio as well as the lowest data error rates.

Published: March 2019

AbstractBackgroundThe study was done to assess high-density lipoprotein (HDL) functionality and to correlate this with paraoxonase 1 (PON1) activity in malnourished children. It aimed to find the effect of malnutrition on changes in PON1 activity, HDL functionality, lipid profile and lipid hydroperoxide formation.MethodsThis case control study included 30 malnourished children (up to age 5 years) and 30 healthy controls in the paediatric inpatient department of SRTR Government Medical College Ambajogai, India. Clinically diagnosed cases depending on anthropometric indices were selected. Serum PON1 activity by using phenyl acetate as a substrate, HDL functionality by haemin by its protection on H2O2and haemin induced LDL oxidation, lipid profile by routine enzymatic methods and lipid hydroperoxide using the FOX2 assay were measured.ResultsMalnourished children had significantly decreased PON1 activity (106.6 ± 12.74** vs. 132.23 ± 28.49 IU/L), HDL functionality (116.55 ± 8** vs. 132.29 ± 10.9%), total cholesterol (TC) (102.5 ± 16** vs. 116.4 ± 12.65 mg/dL), HDL-cholesterol (C) (33.41 ± 9.74** vs. 40.55 ± 5.85 mg/dL) and reduced total protein level (5.56 ± 0.91* vs. 6.06 ± 1.055) higher triglycerides (TG) (146.76 ± 34.97* vs. 125.96 ± 17.21 mg/dL) level and total hydroperoxide (TPX) levels (5.568 ± 1.70** vs. 3.22 ± 1.52 μM/L). *p < 0.05 **p < 0.001. PON1 activity (r2 = 0.576) and TC (r2 = 0.567) shows significant positive correlation with HDL functionality. PON1 activity, HDL-C, HDL functionality and TPX shows independent contribution towards malnutrition in children in multivariate and univariate logistic regression. TC lost its significance in multivariate regression.ConclusionsMalnutrition leads to decrease in HDL functionality and increase in hydroperoxide levels with a decrease in PON1 activity.
Atypical presentation of Leydig cell tumour in three prepubertal patients: diagnosis, treatment and outcomes

Published: March 2019

Abstract

Background
Testicular tumours are uncommon in children, accounting for only 1% of all childhood tumours. Prepubertal Leydig cell tumours actively secrete testosterone and as a result, patients typically present with isosexual precocious pseudopuberty, this being the first cause of consultation. We present three cases of Leydig cell tumours in prepubertal patients with an atypical presentation.

Methods
We studied three cases of Leydig cell tumours in prepubertal boys, who either consulted for testicular asymmetry or were incidentally found to have the tumour in the absence of systemic signs of systemic hyperandrogenism or precocious puberty. In all cases, a well-circumscribed testicular mass was found by testicular ultrasound. The diagnosis was confirmed by histology. In all three cases, testicular enucleation was performed with satisfactory follow-up.

Results
Following the surgical procedure, during the follow-up, all patients showed a normal testicular volume in comparison with the contralateral testis. No complications were seen during follow-up.

Conclusions
A testicular ultrasound in children developing asymptomatic testicular asymmetry might be recommended due to its possible hormonal action locally. An early testicular ultrasound, testicular swelling discrepancies, tumour size and androgen production are key factors in the prognosis and management of this type of tumour.

Abstract
The effectiveness of woven and nonwoven polyester support and coagulation time during membrane formation on the performance and characterization of prepared membranes was studied. The blend membranes of polyvinylchloride with cellulose acetate were prepared by the immersion precipitation process. The prepared membranes were characterized using scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectrophotometry and a mechanical test. Membrane performance was tested using a feed of different synthetic salt solutions. The results proved that the prepared membrane using woven support provided the highest permeate flux and good salt rejection (93.3%) for a salty solution concentration of 20,000 ppm. The stress-strain mechanical test indicated that the excellent mechanical behavior was shown for membranes prepared with a woven support, which has a strength of 12.6 N/cm2 with an elongation of 25 mm for M8. A fouling test was carried out using a mixture solution of salt and humic acid. Using the prepared membranes with woven support provided the best antifouling properties with a flux recovery of 99.2% compared with a flux recovery of 96% using the prepared membrane without support.
Photogrammetric determination of the refractive properties of liquid crystal displays
Authors: Petz Marcus , Dierke Hanno , Tutsch Rainer 
Published: March 2019

Abstract
In phase-measuring deflectometry for measuring reflecting and transparent surfaces, a high-contrast pattern displayed on a liquid crystal screen is usually optically detected. One of the most important non-idealities of liquid crystal displays with regard to the achievable measurement uncertainty is the refraction in the glass substrate, which leads to an angle-dependent offset between the actual location and the observed location of a feature displayed on the screen. Owing to the typical thicknesses and refractive indices of the glass substrates used, this offset reaches several tenths of a millimeter even at moderate viewing angles. In the approach presented here, the refraction-related offset of features displayed on the screen is determined by simultaneous observation of displayed features and features mounted on the screen. The model used so far was improved, so that apart from a distance of the features to be determined before the evaluation no further previous knowledge is necessary. Within the scope of the investigations carried out, statements on the measurement uncertainty of the method could also be made and verified for the first time.

Abstract
Understanding early gene expression in zebrafish embryos is a prerequisite for developmental biology research. In this study, 1,629,447 polymerase reads were obtained from the unfertilized eggs of zebrafish via full-length transcriptome sequencing using the PacBio RS II platform first. Then, 102,920 unique isoforms were obtained by correction, clustering and comparison with the zebrafish genome. 12,782 genes in the genome were captured, accounting for 39.71% of the all annotated genes. Approximately 62.27% of the 12,782 genes have been alternatively spliced. GO and KEGG annotations revealed that the unfertilized eggs primarily stored genes that participate in RNA processing and nuclear protein complex composition. According to this PacBio data that aligned with the genome, 3,970 fusion genes, 819 ncRNAs, and 84 new transcripts were predicted. Illumina RNA-seq and RT-qPCR detection found that the expression of two new transcripts, PB.5289.1 and PB.10209.1, were significantly up-regulated at the 2-cell stage and down-regulated rapidly thereafter, suggesting their involvement in minor ZGA during early embryonic development. This study indicated that the unfertilized eggs of zebrafish may have retained genes directly related to cell division and development to initiate the subsequent development in a limited space and time. On the other hand, NTRs or new transcriptome regions in the genome were discovered, which provided new clues regarding ZGA of MZT during early embryonic development in fish.

Abstract

Background
Financial distress (FD) is common among patients with advanced cancer. Our purpose was to compare the frequency and intensity of FD and its associations with symptom distress and quality of life (QOL) in these patients in France and the U.S.

Materials and Methods
In this secondary analysis of two cross-sectional studies, we assessed data on 292 patients who received cancer care at a public hospital or a comprehensive cancer center in France (143 patients) or the U.S. (149 patients). Outpatients and hospitalized patients over 18 years of age with advanced lung or breast or colorectal or prostate cancer were included. Diagnosed cognitive disorder was considered a noninclusion criterion. Advanced cancer included relapse or metastasis or locally advanced cancer or at least a second-line chemotherapy regimen. Patients self-rated FD and assessed symptoms, psychosocial distress, and QOL on validated questionnaires.

Results
The average patient age was 59 years, and 144 (49%) were female. FD and high intensity were reported more frequently in U.S. patients than in French (respectively 129 [88%] vs. 74 [52%], p &lt; .001; 100 [98%] vs. 48 [34%], p &lt; .001,). QOL was rated higher by the U.S. patients than by the French (69 [SD, 18] vs. 63 [SD, 18], p = .003). French patients had more psychological symptoms such as anxiety (8 [SD, 4] vs. 6 [SD, 5], p = .008). Associations were found between FD and U.S. residence, FD and single status (0.907, p = .023), and FD and metastasis (1.538, p = .036). In contrast, negative associations were found between FD and older age (−0.052, p = .003) and FD and France residence (−3.376, p = .001).

Conclusion
Regardless of health care system, FD is frequent in patients with advanced cancer. U.S. patients were more likely to have FD than French patients but reported better QOL. Further research should focus on factors contributing to FD and opportunities for remediation.
