Apatite with lamellae of sulfide and other phases in ultrahigh-pressure eclogites from Nové Dvory, Moldanubian Zone, Czech Republic
Authors: Faryad Shah Wali , Jedlicka Radim , Perraki Maria 
Published: July 2018

AbstractExsolution lamellae of baryte, Fe sulfides, Cu sulfides and Fe oxides were observed in apatite enclosed in garnet and omphacite and their intergranular spaces in ultrahigh-pressure eclogite in the Moldanubian Zone, Czech Republic. Micro-textural relations and compositional mapping of the apatite indicates a close relationship between the density of the exsolution lamellae and compositional domains that are rich in sulfur and iron. No relation between compositional domains and fluorine or chlorine content or any evidence of apatite metasomatisation was observed. On the basis of cathodoluminescence images, the compositional domains reflect sector zoning in apatite crystals by preferential uptake of elements due to differences in surface charge and morphology on the growth plane. It is concluded that the lamellae are products of exsolution in a closed system resulting from temperature decrease during metamorphism.

Published: July 2018

Purpose Advanced dermatofibrosarcoma protuberans (DFSP) is an exceptionally uncommon disease with scarce literature, especially from developing countries. Molecular testing is unfortunately not available in India, and expert diagnosis by a sarcoma pathologist is available only in tertiary care centers. Materials and Methods We retrospectively analyzed consecutive patients with inoperable DFSP (on the basis of expert histopathology only) who presented to our sarcoma medical oncology clinic from January 2016 to July 2017. Results There were a total of seven patients, with median age of 35 years, predominantly males (85.7%). Fibrosarcomatous variant and metastatic disease were present in six (85.7%) patients. Partial response rates were 71.4%, and overall disease control was 85.7%. Median progression-free survival was 14 months. Conclusion DFSP diagnosis on the basis of expert histopathology in the absence of translocation can help out in targeted therapy–based treatment until translocation testing becomes available. The fibrosarcomatous variant has poor outcome, and further research is needed to help this group of patients.
Correlation Diagrams of Epimeric Stereoisograms for Stereoisomerism of Cyclopropane Derivatives
Authors: Fujita Shinsaku 
Published: July 2018

Abstract
Stereoisomerism of cyclopropanes is systematically discussed by means of stereoisograms and their correlation diagrams. A cyclopropane skeleton is governed by a main RS-stereoisomeric group constructed from its point group D3h, where the main RS-stereoisomeric group generates a set of main stereoisograms. An epimerization process at each of the carbon centers in the cyclopropane skeleton is characterized by an epimeric RS-stereoisomeric group, which generates a set of epimeric stereoisograms. The main RS-stereoisomeric group is combined with the epimeric RS-stereoisomeric groups, generating a stereoisomeric group for characterizing the cyclopropane skeleton. A set of epimeric stereoisograms at each RS-stereogenic center along with a set of main stereoisograms constructs a correlation diagram of stereoisograms. Such correlation diagrams are used to discuss local chirality and local RS-stereogenicity, where the RS-stereogenicity is correlated to the capability of giving RS-stereodescriptors.
Differences are Different: Examining the Effects of Communication Media on the Impacts of Racial and Gender Diversity in Decision-Making Teams

Published: July 2018

Diversity can have positive and negative effects on team decision making. Text communication has been put forth as one solution to addressing this duality of team diversity. Unfortunately, the empirical results have been far from conclusive. We believe that resolving such inconsistencies is crucial to developing a more complete understanding of the use of communication technologies. To accomplish this, we developed a research model based on media synchronicity theory. We empirically tested this model by conducting a laboratory experiment with 46 teams, consisting primarily of men and women self-identified as Caucasians and Asians, performing a decision-making task. The results show that the type of diversity matters. Text communication improved knowledge sharing (i.e., conveyance) and knowledge integration (i.e., convergence) in racially diverse teams but impaired both in gender diverse teams. Knowledge integration was more important to decision quality when racial and gender diverse teams used text communication (but the importance of knowledge sharing was not affected by the communication medium).The online appendix is available at https://doi.org/10.1287/isre.2018.0773 .

Published: July 2018

Abstract
The efficacy of different chemical additives like acetic acid, ammonium molybdate, diethylene triamine pentaacetic acid (DTPA), mannitol, methanol, per acetic acid (PAA), sodium hypochlorite (NaOCl) and sulfamic acid as carbohydrate protector during ozone bleaching of wheat straw pulp was studied. DTPA was found the most effective additive for ozone bleaching followed by the methanol. Using DTPA during ozone treatment improved the delignification efficiency by 13.8 %, bleaching efficiency by 19.8 %, selectivity of ozone by 124 % and reduced the chain scission number of glycosidic linkages in cellulose by 55.3 % compared to that of control. Ozone treatment along with DTPA reduced the Fe, Cu and Mn content in the pulp by 52 %, 27 % and 70 %, respectively. Use of methanol improved the delignification efficiency by 9.0 %, bleaching efficiency by 12.2 %, selectivity by 32.4 % and reduced the chain scission number by 22.2 % compared to that of control. The NaOCl was found to be the most effective for improving the delignification efficiency followed by PAA, they improved the delignification efficiency by 29.3 % and 27.3 %, respectively. The PAA improved the bleaching efficiency to a maximum of 39.9 % followed by 30.2 % with NaOCl.

Abstract
Granulosa cell tumor is a type of neoplasm, which represents 2-5% of all ovarian cancers. About 5% of these tumors are juvenile- type and usually occur to girls before puberty and to women younger than thirty years of age. There are signs premature puberty or premature emergence of secondary sexual characteristics with irregular vaginal bleeding that occur to these kind of patients. To the rare cases, like this, the occurrence of granulosa cell tumors can cause the appearance of hyperandrogenism with high levels of plasma testosterone, leading to virilization which happened to this female patient. We will present the female patient who was 35 years old and which was originally hospitalized to the Clinic for Haematology Clinical Center Kragujevac, because of extreme fatigue accompanied by dizziness. During diagnostics the patient underwent to the complete gynecological examination. After gynecological examinations and necessary diagnostic procedures, it was decided continuing the treatment at the Clinic of Gynecology and Obstetrics Clinical Center Kragujevac, where she underwent a total abdominal hysterectomy with bilateral salpingo- oophorectomy for suspected uterine neoplasm. Histopathological analysis of the obtained material confirmed the presence of follicular cysts of both ovaries and juvenile type granulosa cell tumor on the right ovary; the uterus was enlarged with multiple fibroid tumors. Granulosa cell tumor should be suspected in the cases of girls and young females if there is present an ovarian cyst paired with signs of preterm puberty or hyperestrogenism. In this case, the presence of granulosa cell tumor was masked by signs of hyperandrogenism, which is not so typical, as well as the presence of uterine fibroids who have actually been the main cause for surgical treatment.

Abstract
Potentilla reptans is a little studied plant of the genus Potentilla, the family Rosaceae. The aim of this study is to determine antimicrobial effects of aqueous extracts of P. reptans aerial part and rhizome against standardized bacterial strains.
The antimicrobial activity of aqueous extracts of P. reptans aerial part and rhizome was tested against one fungus, Candida albicans, and two standard bacterial strains, Staphylococcus aureus and Escherichia coli, using an agar diffusion method.
Both examined extracts showed a significant antimicrobial activity against Escherichia coli and Staphylococcus aureus at the concentrations of 10 to 150 mg/ml. The rhizome extract showed stronger antimicrobial effect against the tested strains of bacteria than the aerial part extract.
The obtained results represent preliminary results of antimicrobial activity of this plant and suggest that in future, the studies should examine antimicrobial activity against other bacterial strains and minimum inhibitory concentration.

Published: July 2018

Abstract
The quality and acceptability of the results of the spectral analysis of surface waves (SASW) field test are dependent upon the coherence function, in conjunction with the transfer function. The coherence value is a measure of the quality of the test, and the transfer function denotes the phase lag between signals that are received by the geophones. This article presents a methodology for obtaining high-quality field test data, using a source capable of producing constant impact energy for several repeated impact strikes in an SASW test. Both laboratory and field investigations were performed to assess the effectiveness of the constant impact energy source at improving the coherence value. Tests were conducted on the surface of the soil compacted in a metal box and on the crest of an earthen dam using (a) handheld hammers, resulting in variable impact energy and (b) a drop hammer, dropped from a predetermined fixed height, resulting in constant impact energy. The variation in the shear wave velocity (Vs) profile obtained using the two testing methodologies and its impact on the seismic response analysis of an earthen embankment structure were studied. The SASW tests performed in the laboratory using constant impact energy were more efficient and repeatable than those performed using varying impact energy, and the results showed increased coherence values over a wide range of frequencies. A similar improvement in coherence data was observed in the field studies, and the Vs profiles were found to be significantly different for tests conducted using both methodologies. It was observed that the peak and spectral accelerations at the crest of embankments are significantly different when embankments with different Vs profiles are subjected to seismic excitation. This study emphasizes the importance of performing the SASW test, using a constant impact energy source to obtain a reliable estimate of Vs profiles of subsurface layers.

Published: July 2018

BackgroundCutaneous lichen amyloidosis (CLA) has been reported in some multiple endocrine neoplasia type 2A (MEN 2A) families affected by specific germlineRETmutations C634F/G/R/W/Y or V804M, as a characteristic of the clinical manifestation in ‘MEN 2A with CLA’, one of four variants of MEN 2A, which was strictly located in the scapular region of the upper back.Patient FindingsThis study reports a large south-eastern Chinese pedigree with 17 individuals carrying the MEN 2A-harboring germline C611Y (c.1832G>A)RETmutation by Sanger sequencing. One individual presented MEN 2A-related clinical features, including typical CLA in the interscapular region; another individual exhibited neurological pruritus and scratching in the upper back but lacked CLA skin lesions. Both subjects presented with CLA or pruritic symptoms several years before the onset of medullary thyroid carcinoma (MTC) and/or pheochromocytoma. The remaining 15RETmutation carriers did not exhibit CLA; of these, one presented with MTC and pheochromocytoma, nine with MTC only, two with elevated serum calcitonin and three younger subjects with normal serum calcitonin levels. This family’s clinical data revealed a later diagnosis of MTC (mean age, 45.9 (range: 23–73) years), a lower penetrance of pheochromocytoma (2/17, 11.8%) and CLA (1/17, 5.9%). However, no hyperparathyroidism and Hirschsprung disease were reported in this family.Summary and ConclusionsThis is the first description of a family with MEN 2A-related CLA due to a germlineRETC611Y mutation, which might exhibit a novel and diversified genotype–phenotype spectrum in MEN 2A.

Authors: Lomanova N. A. 
Published: July 2018

The synthesis conditions' influence on the development, thermal behavior, and sintering characteristics was investigated for the nanoand macro-crystalline Bi5FeTi3O15 ceramic materials which had the structure of the perovskite-like four-layered Aurivillius phase. It was shown that the beginning of grains sintering is consistent with the beginning of the surface phase melting, given that the surface phase composition can be governed by the initial mixture's chemical composition changing. The temperatures of crystallization, phase transition, decomposition, sintering activation were defined, as well as the thermal coefficient of the linear expansion of the produced materials was determined.
