Published: September 2016

Aquaculture has been growing fast in Brazil due propitious nature conditions presented to such economic activity. Most of Brazilian production is due to continental aquaculture, especially the fish culture, and is widely focused on exotics species. There are many native species with high breeding potential among them, the tambaqui, Colossoma macropomum, which is the most native species cultivated and has been taking a relevant role in Brazil and in others countries, as well. Tambaqui is native from Amazonas and Orinoco river basins and very appreciated because its fast development, captive fitness, easy training food, resistant, and its high commercial and gastronomy meat value. Nowadays its production represents 14% of Brazilian continental fish culture and several technologies resources has been used to optimize technically and economically its production.

Authors: Kumar H , Kini H , Tiwari A 
Published: September 2016

Background: A majority of gallbladder specimens show changes associated with chronic cholecystitis; however few harbour a highly lethal carcinoma. This study was conducted to review the significant histopathological findings encountered in gallbladder specimens received in our laboratory.Materials and Methods: Four hundred cholecystectomy specimens were studied over a period of five years (May, 2002 to April, 2007) received at department of pathology, Kasturba Medical College, Mangalore, India. Results: Gallstones and associated diseases were more common in women in the 4th to 5th decade as compared to men with M: F ratio of 1:1.33. Maximum number of patients (28.25%) being 41 to 50 years old. Histopathologically, the most common diagnosis was chronic cholecystitis (66.75%), followed by chronic active cholecystitis (20.25%), acute cholecystitis (6%), gangrenous cholecystitis (2.25%),xanthogranulomatous cholecystitis (0.50%), empyema (1%), mucocele (0.25%), choledochal cyst (0.25%), adenocarcinoma gallbladder (1.25%) and normal gallbladders (1%).Conclusion: All lesions were found more frequently in women except chronic active cholecystitis. Gallstones were present in (80.25%) cases, and significantly associated with various lesions (P value 0.009). Pigment stones were most common, followed by cholesterol stones and mixed stones. Adequate sectioning is mandatory in all cases to assess epithelial changes arising from cholelithiasis and chronic cholecystitis as it has been known to progress to malignancy in some cases.
Distribution of hemoglobinopathies in patients presenting for electrophoresis and comparison of result with High performance liquid chromatography
Authors: Jha R 
Published: September 2016

Background: Nearly 226 million carriers of thalassemias and abnormal hemoglobin are present worldwide according to the World Health Organization (WHO). The laboratory plays an important role in the investigation of the thalassemias and hemoglobinopathies. Cellulose acetate electrophoresis at alkaline pH and diagnosis based mainly on visual impression of thickness of band may miss the thalassemic trait patients. The aim of this study was to find out different hemoglobinopathies and thalassemia presenting in our hospital and to compare electrophoresis results with HPLC.Materials and Methods: This study was performed in the hematopathology section of Department of Pathology of Tribhuvan University Teaching Hospital on cases sent for electrophoresis during 18 months period from October 2013 to March 2015 and included hemoglobinopathies and thalassemias identified by either electrophoresis or HPLC. 97 cases fulfilled the inclusion criteria and thus were included in the study. Electrophoresis at alkaline pH was done in all whereas HPLC was performed in 27 cases.Results: A sharp peak of hemoglobinopathies and thalassemias was seen in Tharu community though other communities are also affected. Thalassemia trait was the most common diagnosis (26.8%) followed by sickle cell anemia (21.6%). Electrophoresis was efficient in detecting some alpha thalassemia variants but missed many cases of beta thalassemia trait.Conclusion: Beta Thalassemia trait and sickle cell anemia both are common in Nepal , along with some other hemoglobinopathies A sharp peak of hemoglobinopathies and thalassemias are seen in Tharu community. These abnormal hemoglobins and thalassemias are mainly seen in Terai region. Electrophoresis fails to quantify hemoglobin percentage and thus is not appropriate test in beta thalassemia screening.

Unconstrained Sleep Stage Estimation Based on Respiratory Dynamics and Body Movement
Authors: Hwang Su , Lee Yu , Jeong Do , Park Kwang 
Published: September 2016

SummaryObjectives: The aim of this study is to establish a sleep monitoring method that can classify sleep into four stages in an unconstrained manner using a polyvinylidene fluoride (PVDF) sensor for continuous and accurate estimation of sleep stages.Methods: The study participants consisted of 12 normal subjects and 13 obstructive sleep apnea (OSA) patients. The physiological signals of the subjects were unconstrainedly measured using the PVDF sensor during polysomnography. The respiration and body movement signals were extracted from the PVDF data. Rapid eye movement (REM) sleep was estimated based on the average rate and variability of the respiratory signal. Wakefulness was detected based on the body movement signal. Variability of the respira -tory rate was chosen as an indicator for slow-wave sleep (SWS) detection. Sleep was divided into four stages (wake, light, SWS, and REM) based on the detection results.Results: The performance of the method was assessed by comparing the results with a manual scoring by a sleep physician. In an epoch-by-epoch analysis, the method classified the sleep stages with an average accuracy of 70.9 % and kappa statistics of 0.48. No significant differences were observed in the detection performance between the normal and OSA groups.Conclusions: The developed system and methods can be applied to a home sleep monitoring system.
A POLYTROPIC MODEL FOR SPACE AND LABORATORY PLASMAS DESCRIBED BY BI-MAXWELLIAN ELECTRON DISTRIBUTIONS
Authors: Zhang Yunchao , Charles Christine , Boswell Rod 
Published: September 2016

ABSTRACT
Non-local electron energy probability functions (EEPFs) are shown to have an important effect on the thermodynamic behavior of plasmas in the context of solar wind and laboratory plasmas. A conservation relation is held for electron enthalpy and plasma potential during the electron transport. For an adiabatic system governed by non-local electron dynamics, the correlation between electron temperature and density can be approximated by a polytropic relation, with different indexes demonstrated using three cases of bi-Maxwellian EEPFs. This scenario differs from a local thermodynamic equilibrium having a single polytropic index of 5/3 for adiabaticity.
FAMILIES OF PLAUSIBLE SOLUTIONS TO THE PUZZLE OF BOYAJIAN’S STAR
Authors: Wright Jason T. , Sigurd̵sson Steinn 
Published: September 2016

ABSTRACT
Good explanations for the unusual light curve of Boyajian's Star have been hard to find. Recent results by Montet & Simon lend strength and plausibility to the conclusion of Schaefer that in addition to short-term dimmings, the star also experiences large, secular decreases in brightness on decadal timescales. This, combined with a lack of long-wavelength excess in the star's spectral energy distribution, strongly constrains scenarios involving circumstellar material, including hypotheses invoking a spherical cloud of artifacts. We show that the timings of the deepest dimmings appear consistent with being randomly distributed, and that the star's reddening and narrow sodium absorption is consistent with the total, long-term dimming observed. Following Montet & Simon's encouragement to generate alternative hypotheses, we attempt to circumscribe the space of possible explanations with a range of plausibilities, including: a cloud in the outer solar system, structure in the interstellar medium (ISM), natural and artificial material orbiting Boyajian's Star, an intervening object with a large disk, and variations in Boyajian's Star itself. We find the ISM and intervening disk models more plausible than the other natural models.
AB INITIO COSMOLOGICAL SIMULATIONS OF CR7 AS AN ACTIVE BLACK HOLE
Authors: Smidt Joseph , Wiggins Brandon K. , Johnson Jarrett L. 
Published: September 2016

ABSTRACT
We present the first ab initio cosmological simulations of a CR7-like object that approximately reproduce the observed line widths and strengths. In our model, CR7 is powered by a massive (

) black hole (BH), the accretion rate of which varies between ≃0.25 and ≃0.9 times the Eddington rate on timescales as short as 103 years. Our model takes into account multi-dimensional effects, X-ray feedback, secondary ionizations, and primordial chemistry. We estimate Lyα line widths by post-processing simulation output with Monte Carlo radiative transfer and calculate emissivity contributions from radiative recombination and collisional excitation. We find the luminosities in the Lyα and He ii 1640 Å lines to be

and

erg s−1, respectively, in agreement with the observed values of

and

erg s−1. We also find that the BH heats the halo and renders it unable to produce stars as required to keep the halo metal free. These results demonstrate the viability of the BH hypothesis for CR7 in a cosmological context. Assuming the BH mass and accretion rate that we find, we estimate the synchrotron luminosity of CR7 to be

erg s−1, which is sufficiently luminous to be observed in μJy observations and would discriminate this scenario from one where the luminosity is driven by Population III stars.

Objetivou-se secar polpa de caju em secador de leito de jorro, caracterizar físico-quimicamente os pós produzidos e avaliar o processo de secagem no secador utilizado. A polpa de caju foi adicionada de 10% de maltodextrina e submetida às secagens nas temperaturas de 50, 60 e 70 °C. Os pós produzidos foram analisados quanto ao teor de umidade, açúcares totais, acidez total titulável em ácido cítrico, pH, cinzas, atividade de água e cor, com obtenção dos parâmetros de luminosidade (L*), e cromaticidades a* e b*. Quanto ao processo de secagem foram avaliadas a taxa de remoção do produto (rendimento), a taxa de acúmulo no secador e a taxa de evaporação do leito de jorro. Observou-se que o teor de umidade, a atividade de água e o pH reduziram significativamente com o aumento da temperatura de secagem. Houve concentração das cinzas e aumento significativo nos valores de açúcares totais e acidez total com o aumento da temperatura. A elevação da temperatura de secagem promoveu clareamento significativo nos pós. A taxa de recuperação do produto aumentou com o aumento da temperatura de secagem e a taxa de acumulo diminuiu com a temperatura. A taxa de evaporação não variou. A secagem em leito de jorro é uma boa opção para obtenção da polpa de caju em pó, com melhores resultados dos parâmetros analisados para o pó produzido a 70 °C.

The objectives of the present study were to train a sensory panel and to conduct the sensory characterization of three fish burger formulations. They were made with filleting byproducts of tilapia (Oreochromis niloticus), for inclusion in school meals. Initially, training of the assessors was conducted using the descriptive method for five attributes of the product: fish odor, hardness, juiciness, fish flavor and condiment flavor. The assessors had good repeatability and were able to discriminate the samples. After the training, the panelists evaluated the five attributes of the three developed formulations containing different condiments in the fish burger base formulation: C1) 0.3% oregano, C2) 0.05% basil and C3) 0.05% rosemary. This evaluation was followed by acceptance test and purchase intention. The three formulations had mild fish odor and flavor, in addition to a mild condiment flavor. Additionally, the products had good sensory acceptance and purchase intention.
Imaging in spinal posterior epidural space lesions: A pictorial essay
Authors: Gala Foram B , Aswani Yashant 
Published: September 2016

AbstractSpinal epidural space is a real anatomic space located outside the dura mater and within the spinal canal extending from foramen magnum to sacrum. Important contents of this space are epidural fat, spinal nerves, epidural veins and arteries. Due to close proximity of posterior epidural space to spinal cord and spinal nerves, the lesions present with symptoms of radiculopathy and/or myelopathy. In this pictorial essay, detailed anatomy of the posterior epidural space, pathologies affecting it along with imaging pearls to accurately diagnose them are discussed. Various pathologies affecting the posterior epidural space either arising from the space itself or occurring secondary to vertebral/intervertebral disc pathologies. Primary spinal bone tumors affecting the posterior epidural space have been excluded. The etiological spectrum affecting the posterior epidural space ranges from degenerative, infective, neoplastic - benign or malignant to miscellaneous pathologies. MRI is the modality of choice in evaluation of these lesions with CT scan mainly helpful in detecting calcification. Due to its excellent soft tissue contrast, Magnetic Resonance Imaging is extremely useful in assessing the pathologies of posterior epidural space, to know their entire extent, characterize them and along with clinical history and laboratory data, arrive at a specific diagnosis and guide the referring clinician. It is important to diagnose these lesions early so as to prevent permanent neurological complication.

Transmural coil embolization—alternative technique for management of arterial perforation during subintimal angioplasty
Authors: Damodharan Karthikeyan , Bolia Amman 
Published: September 2016

AbstractSubintimal angioplasty of lower limb arterial occlusion carries a relatively higher risk of vessel perforation compared to transluminal angioplasty. Vessel perforation is a potentially life threatening complication which requires prompt recognition and management. They are usually managed by endovascular techniques such as low-pressure balloon tamponade, covered stents, and coil embolization of the ruptured artery. We describe a technique of treating vessel perforation following balloon angioplasty. Patient developed a large perforation of the proximal superficial femoral artery (SFA) after balloon inflation during subintimal angioplasty of complete SFA occlusion. Following failure of balloon tamponade in sealing the perforation, we successfully treated it by deploying an embolization coil at the site of perforation through the vessel wall followed by balloon tamponade. Our technique could be a useful relatively inexpensive alternative treatment option in the management of vessel perforation compared to covered stents.

Published: September 2016

AbstractSclerosing liposarcoma of epididymis is a rare extratesticular scrotal tumor with variable prognosis. Ultrasonography is the initial imaging modality of choice for the evaluation of scrotal mass and helps to differentiate testicular and extratesticular masses, thereby narrowing down the differential diagnosis. Magnetic resonance imaging with its excellent soft tissue resolution can help in the further characterization of the nature of the tumor. In this case report, we highlight the role of chemical shift imaging in making a confident preoperative diagnosis of liposarcoma thereby guiding optimal and timely management.
CT manifestations of small bowel ischemia due to impaired venous drainage-with a correlation of pathologic findings
Authors: Chou Chung Kuao 
Published: September 2016

AbstractAcute abdominal pain may result from a wide variety of medical and surgical diseases. One of these diseases is small bowel ischemia, which may result in a catastrophic outcome if not recognized and treated promptly. Computed tomography (CT) by its faster image acquisition, thinner collimation, high resolution, and multiplanar reformatted images has become the most important imaging modality in evaluating the acute abdominal conditions. In this article, the author presents a description of the histology of the small bowel, pathophysiology of small bowel change, and a correlation of the pathologic and CT findings of the small bowel injuries due to impaired venous drainage. A convincing correlation of the microscopic mucosal condition with the enhancement pattern of the thickened small bowel wall on CT is useful in definitely describing the mucosal viability.

Abstract. We evaluate the capability of the global atmospheric transport model TM5 to simulate the boundary layer dynamics and associated variability of trace gases close to the surface, using radon (222Rn). Focusing on the European scale, we compare the boundary layer height (BLH) in the TM5 model with observations from the National Oceanic and Atmospheric Admnistration (NOAA) Integrated Global Radiosonde Archive (IGRA) and also with ceilometer and lidar (light detection and ranging) BLH retrievals at two stations. Furthermore, we compare TM5 simulations of 222Rn activity concentrations, using a novel, process-based 222Rn flux map over Europe (Karstens et al., 2015), with harmonised 222Rn measurements at 10 stations. The TM5 model reproduces relatively well the daytime BLH (within 10–20 % for most of the stations), except for coastal sites, for which differences are usually larger due to model representation errors. During night, however, TM5 overestimates the shallow nocturnal BLHs, especially for the very low observed BLHs (< 100 m) during summer. The 222Rn activity concentration simulations based on the new 222Rn flux map show significant improvements especially regarding the average seasonal variability, compared to simulations using constant 222Rn fluxes. Nevertheless, the (relative) differences between simulated and observed daytime minimum 222Rn activity concentrations are larger for several stations (on the order of 50 %) than the (relative) differences between simulated and observed BLH at noon. Although the nocturnal BLH is often higher in the model than observed, simulated 222Rn nighttime maxima are actually larger at several continental stations. This counterintuitive behaviour points to potential deficiencies of TM5 to correctly simulate the vertical gradients within the nocturnal boundary layer, limitations of the 222Rn flux map, or issues related to the definition of the nocturnal BLH. At several stations the simulated decrease of 222Rn activity concentrations in the morning is faster than observed. In addition, simulated vertical 222Rn activity concentration gradients at Cabauw decrease faster than observations during the morning transition period, and are in general lower than observed gradients during daytime. Although these effects may be partially due to the slow response time of the radon detectors, they clearly point to too fast vertical mixing in the TM5 boundary layer during daytime. Furthermore, the capability of the TM5 model to simulate the diurnal BLH cycle is limited by the current coarse temporal resolution (3 h/6 h) of the TM5 input meteorology.
