Analyzing and Estimating Cyberattack Trends by Performing Data Mining on a Cybersecurity Data Set

More than five billion personal information has been compromised over the past eight years through data breaches from notable companies, and the damage related to cybercrime is expected to reach six trillion USD annually by the year of 2021. Interestingly, recent cyberattacks were aimed specifically at credit agencies and companies that hold credit information of their customers and employees. The question is: “Why is it difficult to protect against or evade cyberattacks even for these prestigious companies?”. The purpose of this research is to bring the notion of notorious, rapidly-multiplying cyberthreats. Hence, the research focuses on analyzing cyberattack techniques and finding effectiveness of surveillance methods that companies utilize to protect themselves from cyberattacks. In order to achieve this, we selected cyberattacks information and analyzed the data set through data mining, and the research findings suggest a future trend of cyberattacks efficient countermeasures. From the information gathered through data mining, the research findings suggest a future trend of cyberattacks and efficient countermeasures

A case of desmoid tumor-induced external iliac vein compression misidentified as deep vein thrombosis

Desmoid tumor, also known as desmoid-type fibromatosis, is a rare, intermediate, locally aggressive tumor with a high possibility of local infiltration and recurrence, potentially leading to life-threatening problems. We report a case of a 15-year-old girl who visited the emergency department with a 1-week history of the left leg swelling. A point-of-care ultrasound on the leg showed dilated left femoral and popliteal veins. Subsequently, a computed tomography venogram demonstrated a large pelvic mass compressing the left external iliac vein. She underwent tumor resection, and was uneventfully discharged on day 12

A case of hemophagocytic lymphohistiocytosis caused by an Epstein-Barr virus infection, presenting with unremitting fever and rash

Hemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory syndrome caused by excessive activation of lymphocytes and macrophages, leading to cytokine storm. Infection-associated HLH is most common, and Epstein-Barr virus is the leading triggers. Quick diagnosis is essential for starting the treatment before irreversible damage. We report a case of 16-year-old boy who presented with unremitted fever, jaundice, and erythematous maculopapular rash all over the body. Investigations showed thrombocytopenia, hyperferritinemia, hypertriglycemia, and the bone marrow biopsy showed hemophagocytosis. Epstein-Barr virus antibody was positive. He responded to chemotherapy as per the HLH-2004 protocol and supportive treatment, and was discharged without complication on day 17

Motivation of learning: An assessment of the practicality and effectiveness of gamification within a tertiary education system in Malaysia.

In light of the many criticisms about the Malaysian education system unable to stimulate intrinsic academic motivation among students, this research paper aims to address this issue by assessing the practicality and effectiveness of implementing gamification within education as a viable solution. To do so, the variable factors that determine the effectiveness of gamification need to be identified. Through extensive journal research, the two main factors were identified as past gaming experience (PGE) influenced by intrinsic gaming motivation and personality/learning styles. Through a total of 186 surveys collected, it is found that university students’ perceived effectiveness of gamification is largely independent of past gaming experience and personality/learning styles, except for reducing academic amotivation and stimulating intrinsic motivation. Despite unable to find a suitable model to explain the factors of an effective gamified education, this paper has met its objectives by confirming the fact that gamification does in fact help to tackle the academic motivational problem Malaysia’s education system is currently facing. Furthermore, backed with a mild positive general response from students, it shows that gamification, being independent of past gaming experience and personality/learning style is practical and effective among all students when applied in Malaysia

Proteomic and biochemical analyses reveal the activation of unfolded protein response, ERK-1/2 and ribosomal protein S6 signaling in experimental autoimmune myocarditis rat model

<p>Abstract</p> <p>Background</p> <p>To investigate the molecular and cellular pathogenesis underlying myocarditis, we used an experimental autoimmune myocarditis (EAM)-induced heart failure rat model that represents T cell mediated postinflammatory heart disorders.</p> <p>Results</p> <p>By performing unbiased 2-dimensional electrophoresis of protein extracts from control rat heart tissues and EAM rat heart tissues, followed by nano-HPLC-ESI-QIT-MS, 67 proteins were identified from 71 spots that exhibited significantly altered expression levels. The majority of up-regulated proteins were confidently associated with unfolded protein responses (UPR), while the majority of down-regulated proteins were involved with the generation of precursor metabolites and energy metabolism in mitochondria. Although there was no difference in AKT signaling between EAM rat heart tissues and control rat heart tissues, the amounts and activities of extracellular signal-regulated kinase (ERK)-1/2 and ribosomal protein S6 (rpS6) were significantly increased. By comparing our data with the previously reported myocardial proteome of the Coxsackie viruses of group B (CVB)-mediated myocarditis model, we found that UPR-related proteins were commonly up-regulated in two murine myocarditis models. Even though only two out of 29 down-regulated proteins in EAM rat heart tissues were also dysregulated in CVB-infected rat heart tissues, other proteins known to be involved with the generation of precursor metabolites and energy metabolism in mitochondria were also dysregulated in CVB-mediated myocarditis rat heart tissues, suggesting that impairment of mitochondrial functions may be a common underlying mechanism of the two murine myocarditis models.</p> <p>Conclusions</p> <p>UPR, ERK-1/2 and S6RP signaling were activated in both EAM- and CVB-induced myocarditis murine models. Thus, the conserved components of signaling pathways in two murine models of acute myocarditis could be targets for developing new therapeutic drugs or methods aimed at treating enigmatic myocarditis.</p

Prediction of Alzheimer's disease pathophysiology based on cortical thickness patterns

AbstractIntroductionRecent studies have shown that pathologically defined subtypes of Alzheimer's disease (AD) represent distinctive atrophy patterns and clinical characteristics. We investigated whether a cortical thickness–based clustering method can reflect such findings.MethodsA total of 77 AD subjects from the Alzheimer's Disease Neuroimaging Initiative 2 data set who underwent 3-T magnetic resonance imaging, [18F]-fluorodeoxyglucose-positron emission tomography (PET), [18F]-Florbetapir PET, and cerebrospinal fluid (CSF) tests were enrolled. After clustering based on cortical thickness, diverse imaging and biofluid biomarkers were compared between these groups.ResultsThree cortical thinning patterns were noted: medial temporal (MT; 19.5%), diffuse (55.8%), and parietal dominant (P; 24.7%) atrophy subtypes. The P subtype was the youngest and represented more glucose hypometabolism in the parietal and occipital cortices and marked amyloid-beta accumulation in most brain regions. The MT subtype revealed more glucose hypometabolism in the left hippocampus and bilateral frontal cortices and less performance in memory tests. CSF test results did not differ between the groups.DiscussionCortical thickness patterns can reflect pathophysiological and clinical changes in AD

MR imaging of hepatic lymphangioma

A case of primary hepatic lymphangioma with a microcystic component was incidentally found in a 75-year-old woman. Although ultrasonography (US) and computed tomography (CT) showed a mixed lesion including cystic and solid components, magnetic resonance imaging (MRI) demonstrated the morphologic characteristics of the lesion better than other modalities

PCR Marker-Based Evaluation of the Eating Quality of Japonica Rice (Oryza sativa L.)

Evaluation of eating quality in early breeding generations of rice is critical to developing varieties with better palatability. This paper reports DNA markers associated with eating quality of temperate japonica rice and an evaluation method aided by multiple regression analysis. A total of 30 markers comprising STSs, SNPs, and SSRs were tested for their association with palatability using 22 temperate japonica varieties with different palatability values. Eating quality-related traits of the 22 varieties were also measured. Of the 30 markers, 18 were found to be significantly associated with palatability and, consequently, a model regression equation with an R2 value of 0.99 was formulated to estimate the palatability by the marker data set. Validation of the model equation using selected breeding lines indicated that the marker set and the equation are highly applicable to evaluation of the palatability of cooked rice in temperate japonica varieties

Methylation-dependent regulation of HIF-1 alpha stability restricts retinal and tumour angiogenesis

Hypoxia-inducible factor-1 alpha (HIF-1 alpha) mediates hypoxic responses and regulates gene expression involved in angiogenesis, invasion and metabolism. Among the various HIF-1 alpha posttranslational modifications, HIF-1 alpha methylation and its physiological role have not yet been elucidated. Here we show that HIF-1 alpha is methylated by SET7/9 methyltransferase, and that lysine-specific demethylase 1 reverses its methylation. The functional consequence of HIF-1 alpha methylation is the modulation of HIF-1 alpha stability primarily in the nucleus, independent of its proline hydroxylation, during long-term hypoxic and normoxic conditions. Knock-in mice bearing a methylation-defective Hif1a(KA/KA) allele exhibit enhanced retinal angiogenesis and tumour vascularization via HIF-1 alpha stabilization. Importantly, S28Y and R30Q mutations of HIF-1 alpha, found in human cancers, are involved in the altered HIF-1 alpha stability. Together, these results demonstrate a role for HIF-1 alpha methylation in regulating protein stability, thereby modulating biological output including retinal and tumour angiogenesis, with therapeutic implications in human cancer.1
