Public Sentiment Variations - Interpretationson Twitter

Millions of users share their opinions on Twitter, making it a valuable platform for tracking and analyzing public sentiment. Such tracking and analysis can provide critical information for decision making in various domains. Therefore it has attracted attention in both academia and industry. Previous research mainly focused on modeling and tracking public sentiment. In this work, we move one step further to interpret sentiment variations. We observed that emerging topics (named foreground topics) within the sentiment variation periods are highly related to the genuine reasons behind the variations. Based on this observation, we propose a Latent Dirichlet Allocation (LDA) based model, Foreground and Background LDA (FB-LDA), to distill foreground topics and filter out longstanding background topics. These foreground topics can give potential interpretations of the sentiment variations. To further enhance the readability of the mined reasons, we select the most representative tweets for foreground topics and develop another generative model called Reason Candidate and Background LDA (RCB-LDA) to rank them with respect to their “popularity” within the variation period. Experimental results show that our methods can effectively find foreground topics and rank reason candidates. The proposed models can also be applied to other tasks such as finding topic differences between two sets of documents.
ANÁLISE DA ARBORIZAÇÃO VIÁRIA DO BAIRRO DE PETRÓPOLIS, NATAL, RN: UMA ABORDAGEM PARA DIAGNÓSTICO E PLANEJAMENTO DA FLORA URBANA

Lysyl oxidase‐like 2 is a regulator of angiogenesis through modulation of endothelial‐to‐mesenchymal transition

Lysyl oxidase‐like 2 (LOXL2) belongs to the family of lysyl oxidases, and as such promotes crosslinking of collagens and elastin by oxidative deamination of lysine residues. In endothelial cells (ECs), LOXL2 is involved in crosslinking and scaffolding of collagen IV. Additionally, several reports have shown a role for LOXL2 in other processes, including regulation of gene expression, tumor metastasis, and epithelial‐to‐mesenchymal transition (EMT). Here, we demonstrate an additional role for LOXL2 in the regulation of angiogenesis by modulation of endothelial‐to‐mesenchymal transition (EndMT). LOXL2 knockdown in ECs results in decreased migration and sprouting, and concordantly, LOXL2 overexpression leads to an increase in migration and sprouting, independent of its catalytic activity. Furthermore, LOXL2 knockdown resulted in a reduced expression of EndMT markers, and inhibition of transforming growth factor‐β (TGF‐β)‐mediated induction of EndMT. Interestingly, unlike in EMT, overexpression of LOXL2 alone is insufficient to induce EndMT. Further investigation revealed that LOXL2 expression regulates protein kinase B (PKB)/Akt and focal adhesion kinase (FAK) signaling, both pathways that have been implicated in the regulation of EMT. Altogether, our studies reveal a role for LOXL2 in angiogenesis through the modulation of EndMT in ECs, independent of its enzymatic crosslinking activity.
Donor Notification & Counseling - Our Experience from a Tertiary Care Hospital in Central India

Background: Transfusion services in addition to their prime responsibility of supplying safe blood to the patient, also have a responsibility toward donor safety by means of donor notification & post donation counseling. TTI reactive donor notification is essential for early clinical intervention to minimize their disease and the risk to the partners / close contacts. Materials & Methods: The present observational study was carried out in blood bank of Tertiary Care Hospital in Central India over a period of 4 years involving total (8172) donors including 156 reactive donors. The reactive donors were informed by blood bank counselor about an abnormal test result with an advice to report to blood bank for one to one counseling and referral to the respective department for repeat testing and further management. The response rate of transfusion transmitted infection reactive donors after notification of their abnormal test results was evaluated. Results: During the study period total donation of 8172 units both from voluntary and replacement donors were subjected to routine TTI screening by ELISA. Of these, (156) blood donors were found to be seroreactive. TTI reactive donors (156) for various markers were contacted, 134 (85.9%) telephonically and the remainder 22 (14.1%) who could not be contacted on phone were contacted by post maintaining confidentiality. Seroreactivity of 156 contacted donors was (HIV, HCV, HBSAg, syphilis – 17 : 47 : 91 : 1). Of the 134 contacted donors telephonically, response rate was 93.3 % as 125 donors reported. Of the 22 contacted donors by post, 10 donors responded i.e. response rate was 45.4%. Of the total donors (156), response rate was 86.53% & non response rate was 13.4%. Conclusion: Our study shows that our response rate was increased due to mobile communication. Response rate was also increased due to increased knowledge of infectious diseases which results in self deferral of blood donors belonging to high risk group.
Attitudes and barriers of undergraduate students towards conducting research at Fakeeh college for medical sciences, Jeddah, KSA; a cross-sectional descriptive study

Background: To evaluate attitudes and barriers toward medical research among undergraduate students at Fakeeh College for Medical Science (FCMS), Jeddah, KSA in order to improve their awareness towards medical research criteria and develop action plan to subdue all obstacles.Methods: This descriptive cross-sectional multi-disciplinary study was conducted from March to September 2018 on undergraduate students at FCMS. A questionnaire was completed by 129 students; addressing 6 factors, consisting of 30 questions: 15 questions assessing the attitudes and 15 questions assessing the barriers.Results: Out of the 443 students enrolled in all 3 Programs 129 of the students responded. No significant differences towards research were noted between genders. A comparison between the three programs (medicine, nursing and medical laboratory sciences) towards research revealed that there were no statistically significant differences (P<0.01) between the 3 programs for all factors. Overall, the assessment of students' perception was the highest for factor on the relevance of research to their everyday life with a mean of 4.2 (0.40) whereas, the factor that addressed the research anxiety had the lowest perception with a mean of 3.76 (0.77). Conclusions: The majority of students in the study considered research to be valuable but, at the same time they had little time to conduct research because of their educational tasks. Accordingly, allocating credited hours in their educational schedules for research activities can help encourage students at FCMS to conduct research projects.
Assessment of nectar flow rate and memory for patch quality in the ant Camponotus rufipes


Ants as central place foragers are known to visit repeatedly renewable patches such as extrafloral nectaries, yet the criteria workers use to evaluate their quality, as well as the rules used to decide when to leave the patch, have not been identified. We examined the assessment of nectar flow rate by nectar-feeding ants, Camponotus rufipes. Single workers from a laboratory colony were trained to visit an artificial feeder providing 20% sucrose solution either ad libitum or at controlled flow rates (0.118–2.36 l/min). These flow rates simulate the conditions faced by workers when visiting plant extrafloral nectaries. Ants adjusted their visit times to the different flow rates, so that the time spent at the feeder decreased with increasing nectar flow rates. The volume of nectar collected increased with increasing nectar flow rates, and workers were observed to return to the nest with partially filled crops. To investigate the rules used by ants to decide when to depart from the patch, we confronted experienced workers on their fifth visit with a depleted patch, and recorded the time spent there before leaving. The time depended on the previously experienced flow rate, even though ants always found a depleted patch, indicating that ants arrive at the patch with an expectation about the nectar flow rate, and use as a departure rule an estimate of time that depends on the flow rate previously experienced.
Association of TNF‐308 G>A polymorphism located in tumor necrosis factor a with the risk of developing cervical cancer and results of pap smear

Tumor necrosis factor a (TNFa) is an inflammatory cytokine that plays a crucial role in the immune response and the progression of cervical lesions. There is a growing body of data evaluating the value of a genetic variant in the TNFa gene with the risk of developing cervical cancer. The aim of this study was to explore the association of a variant, TNF‐308 G>A, residing in the TNFa gene with cervical cancer. A total of 91 women with cervical cancer and 161 women as the control group were recruited. DNA was extracted, and Taqman®‐probes‐based assay was used for genotyping. Our results showed that the minor allele frequency was 0.3 in total population, and the frequency of minor allele A was more in the case group compared with the control. The regression models in different genetic models also revealed that the allele A is a potential risk factor for the development of cervical cancer. In particular, in the dominant model, patients with AG and AA genotypes had a higher risk of developing cervical cancer with odds ratio (OR) of 2.75 (95% confidence interval [CI]: 1.57‐4.83, <0.001) and OR of 7.27 (95%CI: 2.5‐20.8, <0.001), compared with the GG genotype. Moreover, a similar outcome was obtained for smear test results. Our study demonstrated that TNF‐308 G>A located on TNF‐a was associated with the risk of cervical cancer, supporting further studies in a larger population and multicenter setting to show the value of emerging markers as risk stratification biomarkers in cervical cancer.
How a warbler chooses its habitat: field support for laboratory experiments

Abstract Abstract. During the non-breeding season hooded warblers, Wilsonia citrina, defend individual territories and segregate by sex into different habitats. Previous laboratory trials suggested that choice was based upon the verticality of plant features: males prefer habitat with more stems growing vertically, whereas females prefer vegetation predominated by oblique angles. To test the proximate cues used by hooded warblers to assess habitat suitability, the effect of hurricane disturbance on the distribution of the sexes was investigated. Hurricane Gilbert crossed the northern portion of the Yucatan Peninsula, Mexico in mid-September 1988 with 320 km/h winds. The abundance and distribution of each sex was compared before and after the storm. After the storm females appeared in forests previously occupied only by males. Analysis of the angles, size, and density of vegetative stems showed that females were found on territories where the verticality of the vegetation was reduced compared with the verticality of vegetation in territories still defended by males. Vegetative height did not differ in male and female territories. This result supports laboratory predictions that primary cues for habitat segregation are based on the relative amounts of vertical and oblique elements in the habitat.
Identification of the Regulatory Region of the Peripheral Myelin Protein 22 (PMP22) Gene That Directs Temporal and Spatial Expression in Development and Regeneration of Peripheral Nerves

Minor changes in PMP22 gene dosage have profound effects on the development and maintenance of peripheral nerves. This is evident from the genetic disease mechanisms in Charcot-Marie-Tooth disease type 1A (CMT1A) and hereditary neuropathy with liability to pressure palsies (HNPP) as well as transgenic animals with altered PMP22 gene dosage. Thus, regulation of PMP22 is a crucial aspect in understanding the function of this protein in health and disease. In this study, we have generated transgenic mice containing 10 kb of the 5'-flanking region of the PMP22 gene, including the two previously identified alternative promoters, fused to a lacZ reporter gene. We show that this part of the PMP22 gene contains the necessary information to mirror the endogenous expression pattern in peripheral nerves during development and regeneration and in mouse models of demyelination due to genetic lesions. Transgene expression is strongly regulated during myelination, demyelination, and remyelination in Schwann cells, demonstrating the crucial influence of neuron-Schwann cell interactions in the regulation of PMP22. In addition, the region of the PMP22 gene present on this transgene confers also neuronal expression in sensory and motor neurons. These results provide the crucial basis for further dissection of the elements that direct the temporal and spatial regulation of the PMP22 gene and to elucidate the molecular basis of the master program regulating peripheral nerve myelination.

Cerebral autoregulation in premature infants during the first 96 hours of life and relationship to adverse outcomes

Objective To test the hypothesis that impaired cerebral autoregulation (ICA) increases the susceptibility of premature infants to adverse outcomes, we determined the relationship of ICA and cerebral reactivity (CR) measured in the first 96 hours of life to the outcome of grade 3 or 4 intraventricular haemorrhage (IVH) and/or death within 1 month. Setting Single-centre level IV neonatal intensive care unit. Patients Neonates 24–29 weeks’ gestation less than 12 hours old with invasive blood pressure monitoring. Design Cerebral saturations and mean arterial blood pressure were recorded every 30 s for 96 hours. For each 10 min epoch, the correlation coefficient (r) was calculated for mean arterial blood pressure versus cerebral saturations. The epoch was considered to have ICA if r>0.5 and CR if r<0. Results Sixty-one subjects were included. During the first 96 hours, ICA occurred 17.6% and CR occurred 41% of recorded time. In those without adverse outcomes, ICA decreased and CR increased by postnatal day (p<0.05). Adjusted for birth weight and gestational age, those with IVH and those who died spent more time with ICA and less time with CR (p<0.05) over the entire recording period. Those with IVH had 1.5-fold increase in time with ICA on day 2 (p=0.021), and decrease in time with CR on day 3 (p=0.036). Compared with survivors, non-survivors spent more time with ICA on days 3 and 4 (p<0.005), and less with CR on day 3 (p=0.032). Conclusion ICA and CR vary by postnatal day and these patterns are associated with adverse outcomes.
Pipeline Diameter Significantly Impacts the Long-Term Fate of Jailed Side Branches during Treatment of Intracranial Aneurysms

BACKGROUND AND PURPOSE: Although covered side branches typically remain patent acutely following Pipeline Embolization Device embolization of intracranial aneurysms, the long-term fate of these vessels remains uncertain. We therefore elected to investigate factors that may influence the long-term patency of these covered side branches. MATERIALS AND METHODS: We retrospectively evaluated the long-term patency of side branches covered by the Pipeline Embolization Device at our institution during treatment of intracranial aneurysms with at least 6 months of conventional angiography follow-up. Procedural and anatomic factors that might influence the fate of covered side branches were explored. RESULTS: One hundred forty-eight Pipeline Embolization Device treatments in 137 patients met the inclusion criteria. In 217 covered side branches, 29 (13.4%) were occluded on follow-up, and 40 (18.4%) were stenotic. All stenoses and occlusions were asymptomatic. In the entire cohort and in the largest subset of ophthalmic arteries, a smaller Pipeline Embolization Device diameter was associated with branch vessel occlusion (P = .001, P = .013). When we considered stenotic and occluded side branches together, smaller Pipeline Embolization Device size (P = .029) and administration of intraprocedural abciximab (P = .03) predicted side branch stenosis/occlusion, while anterior choroidal branch type (P = .003) was a predictor of gross side branch patency. CONCLUSIONS: A smaller Pipeline Embolization Device diameter is associated with delayed side branch stenosis/occlusion following Pipeline Embolization Device treatment, likely due to the higher metal density of smaller caliber devices. Although hemodynamic factors, including the potential for collateral flow, are still paramount in determining the fate of covered side branches, the amount of metal coverage at the side branch orifice also plays an important role.
Predictors of performance in the licensure examination for agriculturists (LEA) in Western Mindanao State University

Success of graduates in the Licensure Examination for Agriculturists (LEA) presents a tangible confirmation of the instructional quality in an HEI. This retrospective, ex post facto study (N=216) investigated predictors of first attempt success in the LEA among Agriculture graduates of Western Mindanao State University (WMSU). Non-academic and academic variables were selected after exhaustive literature review centered on licensure examinations. Unfortunately, there is a need to fill the research gap as far as LEA success predictors are concerned. Heider’s Attribution Theory and Shewhart’s Theory of Prediction contextualized success of WMSU College of Agriculture graduates in the LEA. This study determined the gender, degree program, length of time between graduation and examination, Overall Ability Percentile Rating (OAPR), General Weighted Average (GWA) in English, Mathematics, Crop Science, Soil Science, Crop Protection, Animal Science, Agricultural Economics and Marketing, Agricultural Extension and Communication, and performance in the LEA (pass/fail). The study revealed the predictors and determined the binary logistic regression model: Likelihood of success in the LEA log (p/1-p) = -0.12 (Gender) + 0.35 (Degree program) – 0.02 (Length of time between graduation and examination)+ 0.70 (Overall ability percentile rating) + 0.60 (English GWA) + 0.76 (Mathematics GWA) – 0.16 (Crop Science GWA) – 2.00 (Soil Science GWA) - 0.72 (Crop Protection GWA) – 0.18 (Animal Science GWA) – 1.04 (Agricultural Economics and Marketing GWA) – 0.06 (Agricultural Extension and Communication GWA) + 0.30. The research also revealed that OAPR and Soil Science GWA are good predictors. These outcomes may serve as baseline information that will enhance and modify existing admission policies. Remediation and curriculum development among others are suggested as a result of the current study.
