IMMUNOHISTOLOGIC STUDIES OF SYNOVIOCYTES AND SYNOVIAL EXUDATE CELLS
Authors: Hurd Eric R. , Kinsella T. Douglas , Ziff Morris 
Published: December 2019

Inclusions were demonstrated in normal polymorphonuclear cells incubated with rheumatoid factor-positive synovial fluid. These stained positively for IgG, IgM, and the ß1C component of complement. When normal polymorphonuclear cells were incubated with factor-negative rheumatoid fluid, inclusions were not obtained. However, after addition of IgM rheumatoid factor to such fluids, discrete inclusions were observed with similar staining properties. In a minority of nonrheumatoid fluids, inclusions were also obtained after addition of IgM rheumatoid factor. The phagocytosis of inclusions from synovial fluids after addition of IgM rheumatoid factor suggests the presence of aggregated IgG in these fluids.
Immunofluorescent staining of phagocytic synovial lining cells, isolated from synovial tissue by trypsin digestion, demonstrated a diffuse staining pattern for IgG and the ß1C component of complement in cells from both seropositive and seronegative patients. In seropositive patients, discrete inclusions were also observed which stained positively for IgG, IgM, and ß1C. These findings provide evidence of in vivo phagocytosis of immune complexes from the synovial fluid.

THE BEHAVIOR OF THE NUCLEIC ACIDS DURING THE EARLY DEVELOPMENT OF THE SEA URCHIN EGG (ARBACIA)
Authors: Schmidt Gerhard , Hecht Liselotte , Thannhauser S. J. 
Published: December 2019

The authors wish to correct an error in the paper "The behavior of the nucleic acids during the early development of the sea urchin egg (Arbacia)" (J. Gen. Physiol., 1947–48, 31, 203). Owing to an oversight, the figures for the amounts of various P fractions in a single Arbacia egg have been erroneously expressed in γ x 10–3 units (Tables I and II, page 205; the last two lines of page 206). The figures should have been expressed in γ x 10–5 units.
Thus, the fertilized Arbacia egg contains an average of 20 γ x 10–5 ribonucleic acid P and 0.7 to 1 γ x 10–5 desoxyribonucleic acid P.

Published: December 2019

Abstract
The shiitake mushroom was treated by hydrothermal method to obtain a novel biosorbent. Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FTIR) Spectroscopy and Brunauer–Emmett–Teller (BET) method have been used to characterize the physico-chemical properties of the novel biosorbent. Factors affecting the adsorption properties of Congo red onto biosorbent such as pH, dose, time and temperature were investigated respectively. The experimental data more suitable for the langmuir model than the Freundlich model. The maximum adsorption capacity of the biosorbent obtained by the Langmuir model at 293 K was 217.86 mg g−1. The kinetic study illustrated that the adsorption fit the pseudo-first-order model. Thermodynamic analysis indicated that the adsorption reaction was a spontaneous endothermic reaction.

Published: December 2019

Abstract
Rice husk is considered as a waste in the rice industry but is proficient in manufacturing different materials, such as zeolites, which is produced in large quantities all over the world, for example in Brazil. Zeolite is an adsorbent support material, which can be synthesized from rice husk ash (RHA) with external sources of aluminium (ESA). The scientific community has been conducting several measures to minimize the environmental impacts caused by greenhouse gases. Several mitigation processes are presently investigated, which includes carbon dioxide injections into adsorbent materials (e.g. zeolites). The efficiency of this technology involves a zeolitic material with high crystallinity and high concentrations of SiO2 and Al2O3 (aluminosilicates). In the present work, zeolites have been synthesized from rice husk ash (SiO2 source) and external aluminium sources (Al2O3 - alumina, gibbsite and metakaolin) to fulfill that purpose. With the aid of XRF, XRD, SEM/EDS and FTIR techniques, the zeolitic material was characterized in two distinct crystalline phases: Mordenite and ZSM-5. The synthesis was carried out by the ideal addition of ESA (2.5 g) to RHA. According to the literature, the zeolitic materials formed by the mixture of Mordenite and ZSM-5 can be availed for gas separation and greenhouse gas storage.
Study on production of modified MCrAlY powder with nano oxide dispersoids as HVOF thermal spray feedstock using mechanical milling

Published: December 2019

Abstract
This paper investigates NiCoCrAlY-CeO2 nanocomposite powders prepared by mechanical milling process. At first, micron-sized ceria powder was pre-milled to obtain nano-sized powders and then 1 wt% CeO2 was mixed with the conventional NiCoCrAlY powder and milled under three sets of parameters. The conventional and milled powders were deposited on low carbon steel substrates by HVOF thermal spray technique. X-ray diffraction (XRD), scanning electron microscopy (SEM), field-emission scanning electron microscopy (FESEM) and image analyzing method were used to characterize the prepared powders and coatings. Microstructural characterization showed that the milled powders underwent morphological and phase transitions. Through the microstructural and compositional analyses, it was found that a homogeneous distribution of CeO2 nano-dispersoids in the NiCoCrAlY matrix was obtained. The resulting coatings showed that by using optimized milling parameters, required particle size and suitable morphology for thermal spray can be achieved.
Gatekeeping Stories of Dissent and Mobility
Authors: Pérez-Torres Rafael 
Published: December 2019

AbstractThree recent studies meditate on the significance of narratives by and about racial subjects and exiled radicals in an age of increased social surveillance and control. Elda María Román in Race and Upward Mobility (2017) analyzes popular stories about racially or ethnically identified characters who, seeking upward social mobility, face a quandary. They try to sustain an empowering sense of racial affiliation while seeking to gain upward social and class mobility. Permissible Narratives (2017) by Christopher González analyzes how the form taken by narratives about racial and class affiliation serves to mark ethnic identification. Latinx literary texts that do not follow prescribed forms deliberately undo aesthetic norms and thus enact a kind of transgressive Latinidad. Where the US forms the sociocultural parameters of these two books, Teresa V. Longo’s Visible Dissent (2018) considers the sociocultural interchanges between the US and Latin American writers who articulate a literature of opposition, resistance, and dissent against repressive forms of social and political control. Each study weighs a hope for transformative social change against the power of the efficient, impersonal, even brutal management that comprises modernity.

Published: December 2019

AbstractBackground and AimsScaling from single-leaf to whole-canopy photosynthesis faces several complexities related to variations in light interception and leaf properties. To evaluate the impact of canopy strucuture on gas exchange, we developed a functional–structural plant model to upscale leaf processes to the whole canopy based on leaf N content. The model integrates different models that calculate intercepted radiation, leaf traits and gas exchange for each leaf in the canopy. Our main objectives were (1) to introduce the gas exchange model developed at the plant level by integrating the leaf-level responses related to canopy structure, (2) to test the model against an independent canopy gas exchange dataset recorded on different plant architectures, and (3) to quantify the impact of intra-canopy N distribution on crop photosynthesis.MethodsThe model combined a 3D reconstruction of grapevine (Vitis vinifera) canopy architecture, a light interception model, and a coupled photosynthesis and stomatal conductance model that considers light-driven variations in N distribution. A portable chamber device was constructed to measure whole-plant gas exchange to validate the model outputs with data collected on different training systems. Finally, a sensitivity analysis was performed to evaluate the impact on C assimilation of different N content distributions within the canopy.Key ResultsBy considering a non-uniform leaf N distribution within the canopy, our model accurately reproduced the daily pattern of gas exchange of different canopy architectures. The gain in photosynthesis permitted by the non-uniform compared with a theoretical uniform N distribution was about 18 %, thereby contributing to the maximization of C assimilation. By contrast, considering a maximal N content for all leaves in the canopy overestimated net CO2 exchange by 28 % when compared with the non-uniform distribution.ConclusionsThe model reproduced the gas exchange of plants under different training systems with a low error (10 %). It appears to be a reliable tool to evaluate the impact of a grapevine training system on water use efficiency at the plant level.
Evaluation of different temporal periods between hormone-induced ovulation attempts in the female Fowler’s toad Anaxyrus fowleri

Published: December 2019

AbstractMany amphibian species reinitiate the processes of preparing for reproduction (e.g. oogenesis) soon after breeding indicating hormone-induced ovulation could potentially be achieved out-of-season, which would lead to higher annual fecundity compared to mono-seasonal breeding. Such strategies would be beneficial to captive breeding programs for threatened species that are short-lived, have aging populations or need large numbers of offspring to meet reintroduction goals for species recovery. Unfortunately, little is known regarding how female anurans respond to multiple ovulation events within a year, which could lead to higher annual fecundity compared to mono-seasonal breeding. Thus, we evaluated the effect of temporal period between exogenous hormone stimulation events on egg production using the Fowler’s toad Anaxyrus fowleri as a model species. Female toads (n = 21) were administered hormone therapy twice in 1 year with toads randomly assigned to a treatment of either a 4-, 8- or 12-month recovery period between hormone stimulations. Ovulation was induced using two priming doses of human chorionic gonadotropin (100 IU; hCG) 72 h apart, followed by a resolving dose of hCG (500 IU) plus gonadotropin releasing hormone analogue (GnRHa; 15 μg) given 24 h after the second priming injection. Measured response variables include the number of females ovulating after treatment, total number of eggs produced and percent fertilization, neurula and tadpole development. No significant treatment effects were observed for any response variable (P &gt; 0.05). Findings from this study suggest that hormone therapy can be administered in a bufonid species every 4 or 8 months without significantly affecting the number of ovulating females, egg production, fertilization, neurulation or tadpole development. By collecting gametes out-of-season or multiple times throughout the year, captive breeding programs could potentially increase tadpole production for reintroductions as well as extend the breeding window in captivity.

AbstractBackground and AimsCrohn’s disease [CD] can involve any part of the gastrointestinal tract. We aimed to characterize the clinical, endoscopic and histological features and treatment outcomes of CD patients with oesophageal involvement.MethodsWe collected cases through a retrospective multicentre European Crohn’s and Colitis Organisation CONFER [COllaborative Network For Exceptionally Rare case reports] project. Clinical data were recorded in a standardized case report form.ResultsA total of 40 patients were reported (22 males, mean [±SD, range] age at oesophageal CD diagnosis: 25 [±13.3, 10–71] years and mean time of follow-up: 67 [±68.1, 3–240] months). Oesophageal involvement was established at CD diagnosis in 26 patients [65%] and during follow-up in 14. CD was exclusively located in the oesophagus in two patients. Thirteen patients [32.2%] were asymptomatic at oesophageal disease diagnosis. Oesophageal strictures were present in five patients and fistulizing oesophageal disease in one. Eight patients exhibited granulomas on biopsies. Proton-pump inhibitors [PPIs] were administered in 37 patients [92.5%]. Three patients underwent endoscopic dilatation for symptomatic strictures but none underwent oesophageal-related surgery. Diagnosis in pre-established CD resulted in treatment modifications in 9/14 patients. Clinical remission of oesophageal disease was seen in 33/40 patients [82.5%] after a mean time of 7 [±5.6, 1–18] months. Follow-up endoscopy was performed in 29/40 patients and 26/29 [89.7%] achieved mucosal healing.ConclusionIn this case series the endoscopic and histological characteristics of isolated oesophageal CD were similar to those reported in other sites of involvement. Treatment was primarily conservative, with PPIs administered in the majority of patients and modifications in pre-existing inflammatory bowel disease-related therapy occurring in two-thirds of them. Clinical and endoscopic remission was achieved in more than 80% of the patients.
Personal perspective on inequality: conference attendance as an Iranian citizen
Authors:   Anonymous
Published: December 2019

ABSTRACT
Science is expected to be borderless and inclusive of any interested individuals. The efforts made by academic institutions to promote diversity and inclusiveness are unfortunately undermined by discriminatory government policies. Iranian researchers suffer from limited mobility for attending scientific gatherings and are underrepresented due to lack of exposure, as they can be subject to discrimination for entering some countries, e.g. the US travel ban. As an Iranian citizen, I was denied an academic visitor visa to attend FEMS congress in Glasgow in 2019 to share my Ph.D. research results. This resulted in considerable waste of time, funds and efforts leaving me with a great deal of pain and frustration. In this article, I share my story to help raise awareness about compromised equity in the scientific community as a result of institutional discrimination and racism.

Abstract
A 59-year-old female presented with severe headache and trouble of consciousness. The CT showed a subarachnoid hemorrhage FISHER IV with a hematoma of the right cerebellum. The angiography discovered a persistent left trigeminal artery associated with an aneurysm of the right posterior meningeal artery. The attempt of embolization failed and the patient suffered cerebral vasospasm and died. The persistence of a trigeminal artery is found in 0.1–0.6% of the population. It is the most frequent embryological carotid-vertebral anastomosis. It appears at the fifth week of development and disappears when the embryo reaches 5–7 mm. This embryological persistence is associated with numerous vascular abnormalities. The literature review showed the presence of those aneurysms in the trigeminal artery itself or the communicating artery. The association that we described is the first to our knowledge. Therefore, this association is particular and interesting to expose.
Relations Between Variables and Trends Over Time in Rdd Telephone and Nonprobability Sample Internet Surveys
Authors: Pasek Josh , Krosnick Jon A 
Published: December 2019

Abstract
Survey researchers today can choose between relatively higher-cost probability sample telephone surveys and lower-cost surveys of nonprobability samples of potential respondents who complete questionnaires via the internet. Previous studies generally indicated that the former yield more accurate distributions of variables, but little work to date has explored the impact of mode and sampling on associations between variables and trends over time. The current study did so using parallel surveys conducted in 2010 focused on opinions, events, behavioral intentions, and behaviors involving that year’s Decennial Census. A few comparisons indicated that the two data streams yielded similar results, but the two methods frequently yielded different results, often strikingly so, and the results yielded by the probability samples seem likely to be the more accurate ones.
Risk of predation alters resource allocation in Daphnia under food limitation
Authors: Klintworth Sandra , Von Elert Eric 
Published: December 2019

AbstractLife-history theory predicts that animals adjust their resource allocation to somatic growth or to reproduction to maximize fitness. Resource allocation in Daphnia is known to respond to quantitative food limitation as well as to kairomones released from predators. Here we investigated in a full-factorial design how kairomone from larvae of Chaoborus flavicans, a gape-limited predator, and food quantity (0.5 mg C/L versus 1.5 mg C/L) affect the fatty acid allocation of D. pulex. Low food diminished somatic growth, clutch size and clutch biomass and increased neckteeth formation in response to the kairomone. Low food further led to increased fatty acid amounts per individual egg as well as to increased fatty acid content in eggs and to increased relative fatty acid allocation to reproduction. The latter effect was suppressed by kairomone of Chaoborus, whereas on high food the provision of eggs was further enhanced. We also found that more eicosapentaenoic acid was retained in the body of mothers in the presence of the predator at low food concentrations. These findings indicate that under food limitation and in the presence of kairomone from Chaoborus larvae, Daphnia switches from allocation into current reproduction to investment into future reproductive events.
Psychological Subgrouping to Assess the Risk for the Development or Maintenance of Chronic Musculoskeletal Pain
Authors: Linton Steven J. , Kienbacher Thomas 
Published: December 2019

Background:
Because musculoskeletal pain problems are so prevalent, new methods of evaluating and treating patients are needed to increase effectiveness. Subgrouping is a method wherein patients are classified into defined groups on the basis of psychosocial factors with the expectation of more specific and tailored treatments can be prescribed for them. For those seeking care for a new episode, the risk of developing chronic pain-related disability is assessed, whereas, for those with existing pain, the risk for the maintenance of the chronic pain problem is evaluated.

Aim:
The purpose of this narrative review is to examine how patients are classified into subgroups with regard to methods of evaluation and to ascertain whether subgrouping actually facilitates treatment.

Results:
For the development of disability, screening tools, for example, the Örebro Musculoskeletal Pain Screening Questionnaire, accurately stratify patients into groups (eg, high, medium, low risk) that predict future pain-related work disability. In addition, several studies show that treatments that directly key in on risk groups enjoy enhanced outcomes compared with treatment as usual. For the maintenance of chronic musculoskeletal pain problems, there are several instruments that classify patients into specific groups or profiles, for example, on the basis of the avoidance and endurance model or the International Classification of Functioning, Disability and Health (ICF) assessment. Although some evidence shows that these classifications are related to treatment outcome, we found no study that directly tested a system for providing treatment matched to the subgrouping for maintenance.

Conclusions:
We conclude that it is possible to reliably subgroup patients with musculoskeletal problems. Likewise, treatments that address the risk factors in the screening procedure may enhance outcomes compared with treatment as usual. More work is needed, however, to better understand the mechanism, so that assessment methods can be improved, and treatment specific to subgroups can be developed and evaluated.
