Primary Left Atrial Leiomyosarcoma: Literature Review and Lessons of a Case

Primary cardiac sarcoma is an uncommon disease. In particular, leiomyosarcoma of cardiovascular origin is extremely rare. Half of all cardiac leiomyosarcomas are located in the left atrium. Due to the extreme rarity of left atrial leiomyosarcoma, there is no great experience in its management. This review includes a report of a case of left atrial leiomyosarcoma followed up over 45 months. The literature review examines the distribution of left atrial leiomyosarcoma, the physiological reasons for the tendency of cardiac leiomyosarcoma to be localized to the left atrial cavity, the clinical and physical appearance of this disease, and the key differences between left atrial leiomyosarcoma and the most common left atrial tumor, myxoma. The morphological features, using light and electron microscopy and immunochemical staining, are discussed. Treatment modalities including adjuvant therapy and surgical resection are examined and their effectiveness compared. Opinions regarding the results and optimal treatment of leiomyosarcoma are not always in agreement. This highlights the need for inter-hospital comparison to determine the optimal treatment regimen.

The findings revealed that Students taught Mathematics through Activity based method differ significantly in Achievement Motivation as compared to the control group (Traditional Teaching method). Results also show that the students taught Mathematics through Activity based method differ significantly in Academic Achievement as compared to the Control group (Traditional Teaching method).
Degenerate Motion Analysis for Aided INS with Spatial and Temporal Calibration

In this paper we perform in-depth observability analysis for both spatial and temporal calibration parameters of an aided inertial navigation system (INS) with global and/or local sensing modalities. In particular, we analytically show that both spatial and temporal calibration parameters are observable if the sensor platform undergoes random motion. More importantly, we identify four degenerate motion primitives that harm the calibration accuracy and thus should be avoided in reality whenever possible. Interestingly, we also prove that these degenerate motions would still hold even in the case where global pose measurements are available. Leveraging a particular multi-state constrained Kalman filter (MSCKF)-based vision-aided inertial navigation system (VINS) with online spatial and temporal calibration, we perform extensively both Monte-Carlo simulations and real-world experiments with the identified degenerate motions to validate our analysis.
Automatic Gleason grading of prostate cancer using quantitative phase imaging and machine learning

Abstract. We present an approach for automatic diagnosis of tissue biopsies. Our methodology consists of a quantitative phase imaging tissue scanner and machine learning algorithms to process these data. We illustrate the performance by automatic Gleason grading of prostate specimens. The imaging system operates on the principle of interferometry and, as a result, reports on the nanoscale architecture of the unlabeled specimen. We use these data to train a random forest classifier to learn textural behaviors of prostate samples and classify each pixel in the image into different classes. Automatic diagnosis results were computed from the segmented regions. By combining morphological features with quantitative information from the glands and stroma, logistic regression was used to discriminate regions with Gleason grade 3 versus grade 4 cancer in prostatectomy tissue. The overall accuracy of this classification derived from a receiver operating curve was 82%, which is in the range of human error when interobserver variability is considered. We anticipate that our approach will provide a clinically objective and quantitative metric for Gleason grading, allowing us to corroborate results across instruments and laboratories and feed the computer algorithms for improved accuracy.
Binaural Cue Selection for Source Localization : Motivation and Experiments

Recently, a binaural model for source localization in complex listening situations has been proposed (Faller and Merimaa, 2004). Concurrently active sources and reflections have the effect that the binaural cues at the ear entrances often do not anymore directly relate to the source directions. The values of the binaural cues are determined by the superposition of the various sources and reflections. The proposed model assumes that for localizing sources the binaural cues are only used at time instants when they determine a direction of a source correctly. These time instants are determined with the help of the interaural coherence which is continuously computed. A number of simulations are presented, including a scenario with concurrent speech and determination of an echo threshold.
Mastitis pathogens isolated from samples of milk in dairy cows herds of Slovak spotted cattle

Breeding of ruminants with market milk production represents a significant proportion of livestock production in Slovakia. Mastitis is one of the biggest problems of dairy producer’s cause’s great losses in the livestock economy. Cows that are infected with mastitis generally produce less milk, use longer time to get pregnant, lose more body condition, and are also more likely to be culled early. Besides affecting production and the profitability it also has a major impact on the welfare of the cows. The aim of this study was to evaluate occurrence and etiology of mastitis in two dairy herds of Slovak spotted cattle. The diagnosis of mastitis was performed based on clinical examination of the udder, macroscopic evaluation of milk, with the evaluation of Californian mastitis test (CMT) and bacteriological analysis of individual raw milk samples. From total 904 and 612 quarter cow’s milk samples were 26,1% and 13,5% positive to CMT, respectively. The prevalence of intramammary infection (IMI) in the monitored herds of cows was 17.0% to 12.4%, respectively. In both herds were confirmed predominantly subclinical forms of IMI. The highest percentage of etiological agents in all monitored herds had coagulase negative staphylococci (CNS) and coagulase positive staphylococci (CPS) especially Staphylococcus aureus. Except for staphylococci were E. coli, Aerococcus viridans and Streptococcus spp. most frequently pathogens isolated from dairy cows. Given the variety of factors causing IMI milk production and economic prosperity of dairy herds will primarily depend on the expertise and skills to implement preventive anti-mastitis methods, and technological systems to own agricultural production.
The effects of time compression on the auditory processing abilities of learning disabled children.

This study measured the ability of ten 8- and ten 12-yr-old learning disabled (LD) children of normal intelligence (WISC-R) to discriminate phonemic contrasts in sentential stimuli (Subtest 13 of the Carrow Auditory Visual Abilities Test) presented at a 50% time-compression rate. Their group responses were compared statistically to similar data gathered earlier (May et al, J. Aud. Res., 1984, 24, 205-211) from 6-, 8-, and 10-yr-old normal children and young adults. LD Ss exhibited auditory processing capacities reminiscent of an earlier level of operation (e.g., the group of LD Ss with mn age of 12.8 yrs yielded group performance equivalent to that of normal 6- and 8-yr-olds), and also manifested marked differences in their feature- and frequency-processing abilities. These data indicate that contributing to the learning difficulties of LD children may very well be delays in auditory development and anomalies in auditory-feature processing.

Submission by the Stockholm Environment Institute relating to the Adaptation Committee ’ s mandates stemming from Decision 1 / CP . 21 – Transnational climate change impacts

Climate change mitigation is widely regarded as a global problem, but climate change impacts and adaptation are typically described as regional or local issues. This reflects the locationspecific nature of physical impacts, but it fails to recognize the many interconnections among countries and regions, particularly in an increasingly globalized economy. This paper introduces a new framework for examining climate change impacts and adaptation needs from an international perspective. Based on this framework, we develop indicators of country-level exposure to what we call the transnational impacts of climate change: those that occur in one place as a consequence of climate impacts somewhere else. The indicators allow us to quantify each country’s exposure across multiple dimensions. We also construct a composite index: the Transnational Climate Impacts Index. The paper explains the rationale and methodology by which indicators were selected, and invites feedback and suggestions from readers on how to further develop this research. We see significant opportunities to strengthen and deepen the quantitative assessment of exposure to transnational climate impacts, including via applications of the framework at the national rather than global level.

Antifungal and phytochemical properties of Tinospora cordifolia , Azadirachta indica and Ocimum sanctum leaves extract

In the present study the aqueous, methanol, ethanol and acetone extract of Tinospora cordifolia, Azadirachta indica and Ocimum sanctum leaves extract were screened for the presence of phytochemical components and tested for antifungal activity against Candida albicans, Aspergillus niger, Aspergillus fumigatus, Microsporum gypseum and Trichophyton rubrum Results revealed the presence of anthraquinones, alkaloids, saponins, tannins, glycosides and phenolics. The acetone extracts had wide range of antibacterial activity against bacterial pathogens than the ethanol and methanol extract, where as aqueous extract were slightly higher antibacterial activity as ethanol extract. Antifungal activity of various extract of leaves of Tinospora cordifolia, Azadirachta indica and Ocimum sanctum would lead to the establishment of some compounds that could be used to formulate new and more potent antimicrobial drugs of natural origin.

Study of the Impact of Ice Formation in Leads upon the Sea Ice Pack Mass Balance Using a New Frazil and Grease Ice Parameterization

AbstractLeads are cracks in sea ice that often form because of deformation. During winter months, leads expose the ocean to the cold atmosphere, resulting in supercooling and the formation of frazil ice crystals within the mixed layer. Here the authors investigate the role of frazil ice formation in leads on the mass balance of the sea ice pack through the incorporation of a new module into the Los Alamos sea ice model (CICE). The frazil ice module considers an initial cooling of leads followed by a steady-state formation of uniformly distributed single size frazil ice crystals that precipitate to the ocean surface as grease ice. The grease ice is pushed against one of the lead edges by wind and water drag that the authors represent through a variable collection thickness for new sea ice. Simulations of the sea ice cover in the Arctic and Antarctic are performed and compared to a model that treats leads the same as the open ocean. The processes of ice formation in the new module slow down the refreezing o.
Image copy-move tamper blind detection algorithm based on integrated feature vectors

Copy-Move method is a simple effective tampering algorithm in digital image tamper, and regarding regional copy-move post-processing, existing detection algorithms are poor in robustness and high in time complexity. This dissertation provides a blind detection algorithm based on integrated eigenvector. This algorithm extracts from each image block the Tamura texture features and average gray-value information to make up integrated feature vectors and then sorts the feature vectors in a dictionary sorting method, and finally calculates the similarity among the image blocks by using confidence distance so as to detect and locate any tampered regions. The experimental result suggests that this algorithm can not only effectively detect and locate the tampered image regions but also effectively resist multiple post-processing of regional copy-move, including rotation, Gaussian noise addition, high/low pass filtering and JPEG compression, showing higher accuracy and lower time complexity than other algorithms.

An Ultrasound-based Indoor Localization Using Gaussian ASK Modulation

This paper suggests an Amplitude Shift Keying(ASK) modulation approach as an ultrasound based localization for smartphone users. Ultrasound based localization methods have used a chirp signal to estimate the distance from beacons. However, the matched filter for extracting the pulse from a chirp signal should perform convolutions which have high computational load. Also, chirp-based systems can support only limited number of beacons due to the difficulty in encoding beacon IDs. In order to avoid this problem, we propose a modulation-based localization that exploits the ASK. We apply a Gaussian filter to reduce the noise caused by the out-of-band power. We implement a software-defined modulator/demodulator which can be used between the smartphones and the beacons in the near-ultrasound frequency band. From our modulation-based scheme, we can achieve 15cm location accuracy at 90% of the measurements.
1 Comparative metacognition

We argue that comparative psychologists have been too quick to jump to metacognitive interpretations of their data. We examine two such cases in some detail. One concerns so-called “uncertainty monitoring” behavior, which we show to be better explained in terms for first-order estimates of risk. The other concerns informational search, which we argue is better explained in terms of a first-order curiosity-like motivation that directs questions at the environment.
MEK Inhibition Targets Cancer Stem Cells and Impedes Migration of Pancreatic Cancer Cells In Vitro and In Vivo

Pancreatic ductal adenocarcinoma (PDAC) remains a devastating disease with a very poor prognosis. At the same time, its incidence is on the rise, and PDAC is expected to become the second leading cause of cancer-related death by 2030. Despite extensive work on new therapeutic approaches, the median overall survival is only 6-12 months after diagnosis and the 5-year survival is less than 7%. While pancreatic cancer is particularly difficult to treat, patients usually succumb not to the growth of the primary tumor, but to extensive metastasis; therefore, strategies to reduce the migratory and metastatic capacity of pancreatic cancer cells merit close attention. The vast majority of pancreatic cancers harbor RAS mutations. The outstanding relevance of the RAS/MEK/ERK pathway in pancreatic cancer biology has been extensively shown previously. Due to their high dependency on Ras mutations, pancreatic cancers might be particularly sensitive to inhibitors acting downstream of Ras. Herein, we use a genetically engineered mouse model of pancreatic cancer and primary pancreatic cancer cells were derived from this model to demonstrate that small-molecule MEK inhibitors functionally abrogate cancer stem cell populations as demonstrated by reduced sphere and organoid formation capacity. Furthermore, we demonstrate that MEK inhibition suppresses TGFβ-induced epithelial-to-mesenchymal transition and migration in vitro and ultimately results in a highly significant reduction in circulating tumor cells in mice.

Field Trials of Tissue Culture Taro ( Colocasia esculenta ( L . ) Schott ) in the Northern Mariana Islands

The Commonwealth of the Northern Mariana Islands consists of a group of islands in the western pacific. Taro (Colocasia esculenta (L.) Schott) is one of the important subsistence food crops grown in the Northern Marianas. The quality and production of taro crop has been severely affected in recent years by the introduction of major diseases and pests impacting taro production. The downturn in the islands’ economy, natural disasters such as droughts and typhoons, and paucity of quality planting material have also had considerable constraints on taro production in the Commonwealth. The Cooperative Research, Extension and Education Service Department of the Northern Marianas College introduced a tissue culture program for the in-vitro multiplication and propagation of quality planting material of taro. New varieties of taro produced in-vitro were introduced from the regional certified institution and evaluated for tolerance to insect pests and diseases, plant growth, corm quality, high yield, taste and superior agronomic characters. Twenty-three varieties of taro propagated through tissue culture were tested at the Agriculture Experiment Station. Field trials and taste testing of new varieties were successfully conducted throughout the islands of Saipan, Rota and Tinian. Results indicated that new varieties performed well in local soil and climatic conditions of the Northern Mariana Islands. Japanese varieties (CA/JP-01, 06 and 09) rated excellent for taste, quality of corms, easy cooking, plant growth and yield comparable to other varieties. The selected varieties of taro were identified as the economically and culturally important ones that have been tested for superior characteristics in the region. _____________________________________________________________________________________________________________
Healing of a porcine burn wound dressed with human and bovine amniotic membranes

The effects of amniotic membranes (AMs), either fresh human and bovine AMs or acellular bovine AMs, on wound healing were compared among the burn wounds of porcine skin. Six pigs were chosen for the study, and we created deep second‐degree contact burns on them with a digitally controlled aluminum thermal block. Then we applied the dressings to some of the wounds using fresh human and bovine AMs, acellular bovine AMs, polyurethane foam, or no dressing. We evaluated the pigs for (1) the rate of epithelialization, (2) histological grading, and (3) infections. We found that the AM groups showed better wound‐healing effects than did the polyurethane foam and no dressing groups, and these differences were statistically significant. However, the differences between the AM groups were not statistically significant. Wound cultures showed higher infection rates in the control and polyurethane foam groups compared with the other groups. Our study showed that fresh or acellular bovine AMs provided similar efficacy for wound healing as did the fresh human AMs.
