Distributed Denial of Service Attack Detection in Application Layer Based on User Behavior

Distributed Denial of Service (DDoS) attacks are a threat to the security of red. In recent years, these attacks have been directed especially towards the application layer. This phenomenon is mainly due to the large number of existing tools for the generation of this type of attack. The highest detection rate achieved by a method in the application capacity is 98.5 percent. Therefore, the problem of detecting DDoS attacks persists. In this work an alternative of detection based on the dynamism of the web user is proposed. To do this, evaluate the user's characteristics, mouse functions and right click. For the evaluation, a data set of 11055 requests was used, from which the characteristics were extracted and entered into a classification algorithm. To that end, it can be applied once in Java for the classification of real users and DDoS attacks. The results showed that the evaluated characteristics achieved an efficiency of 100 percent. Therefore, it is concluded that these characteristics show the dynamism of the user and can be used in a detection method of DDoS attacks.
A new ancient lineage of frog (Anura: Nyctibatrachidae: Astrobatrachinae subfam. nov.) endemic to the Western Ghats of Peninsular India

The Western Ghats (WG) is an escarpment on the west coast of Peninsular India, housing one of the richest assemblages of frogs in the world, with three endemic families. Here, we report the discovery of a new ancient lineage from a high-elevation massif in the Wayanad Plateau of the southern WG. Phylogenetic analysis reveals that the lineage belongs to Natatanura and clusters with Nyctibatrachidae, a family endemic to the WG/Sri Lanka biodiversity hotspot. Based on geographic distribution, unique morphological traits, deep genetic divergence, and phylogenetic position that distinguishes the lineage from the two nyctibatrachid subfamilies Nyctibatrachinae Blommers-Schlösser, 1993 and Lankanectinae Dubois & Ohler, 2001, we erect a new subfamily Astrobatrachinae subfam. nov. (endemic to the WG, Peninsular India), and describe a new genus Astrobatrachus gen. nov. and species, Astrobatrachus kurichiyana sp. nov. The discovery of this species adds to the list of deeply divergent and monotypic or depauperate lineages with narrow geographic ranges in the southern massifs of the WG. The southern regions of the WG have long been considered geographic and climatic refugia, and this new relict lineage underscores their evolutionary significance. The small range of this species exclusively outside protected areas highlights the significance of reserve forest tracts in the WG in housing evolutionary novelty. This reinforces the need for intensive sampling to uncover new lineages and advance our understanding of the historical biogeography of this ancient landmass.
Unusual foreign object in a tooth: A case report and review of literature

Foreign body impactions in the tooth are common findings in the oral cavity of children because of their frequent habits of placing various objects in their mouth. The present case describes an 11-year-old boy with a foreign object in the maxillary left first molar tooth of which he was unaware. Foreign objects can not only be a source of infection but also be aspirated or ingested by the child. The discovery of foreign objects in the teeth is usually accidental. A detailed case history, consisting of a history of the ordinary placement of the object and clinical and radiographic examinations is necessary to determine the nature, size, and location of the foreign body, as well as the difficulty involved in its retrieval. The foreign object may sometimes fracture inside the tooth during exploration by the parent or child. Such an object may act as a potential source of infection and lead to complications.
Physical Functioning Among Patients Aging With Human Immunodeficiency Virus (HIV) Versus HIV Uninfected: Feasibility of Using the Short Physical Performance Battery in Clinical Care of People Living With HIV Aged 50 or Older

Abstract Background The Short Physical Performance Battery (SPPB) is a well regarded physical functioning assessment including balance, gait speed, and chair-stand tests. Its use has not been widely assessed in human immunodeficiency virus (HIV) care. We evaluated the feasibility of integrating the SPPB into care of aging people living with HIV (PLWH) and compared SPPB performance with aged HIV-uninfected individuals. Methods We enrolled PLWH aged ≥50 at 3 HIV clinics and compared their SPPB scores and subscores with older HIV-uninfected adults in the Health, Aging, and Body Composition (Health ABC) study. We conducted regression analyses on age stratified by sex and adjusting for site, and we calculated percentage variance explained by age among PLWH and HIV-uninfected adults. Results The SPPB was feasible to implement in clinical care and did not require licensed professionals; 176 PLWH completed it with a mean completion time of 7.0 minutes (standard deviation = 2.6). Overall mean SPPB score among PLWH was 10.3 (median 11.0, 25th percentile 9.0, 75th percentile 12.0). People living with HIV were younger than HIV-uninfected individuals (55 vs 74 years old). Mean SPPB scores and most subscores were similar among PLWH and older HIV-uninfected individuals despite the ~20-year age difference. Regression analyses of gait speed revealed similar slopes in PLWH and HIV-uninfected individuals; however, separate intercepts were needed for PLWH. Mean gait speeds were faster in older HIV-uninfected men and women (P < .01), yet relationships with age within PLWH and HIV uninfected were similar. Conclusions The SPPB can be implemented into busy HIV clinics. Despite the ~20-year age difference, mean scores were similar among PLWH and older HIV-uninfected individuals, although gait speed was faster among HIV-uninfected individuals.
Modified frailty as a novel factor in predicting the response to cardiac resynchronization in the elderly population

Background The response to cardiac resynchronization therapy (CRT) is an important element of the treatment of advanced heart failure, especially in the geriatric population. The aim of the study was to examine the impact of frailty syndrome on the response to treatment with CRT. Methods Two hundred and forty-six patients of 60 years or older (aged 73.35±6.95; 22.4% women) with an implanted CRT were included in this single-center prospective study. There was a 12-month follow-up. The Tilburg Frailty Indicator was used to determine frailty (5 or more points). The response to CRT was evaluated based on an analysis of clinical criteria. Results One hundred and sixty-nine of 246 (68.9%) patients were found to be clinical CRT responders. Frailty syndrome was recognized in 173 (70.32%). There were 63.0% responders in the frailty-affected group, whereas there were statistically more responders (79.5%) in the robust group (P=0.0116). In the logistic regression, frailty emerged as an independent predictor of the response to CRT (OR=0.81, 95% CI=0.71–0.92; P=0.0008). The area under the curve of the ROC curve for frailty in the responders to CRT was 0.62. The cut-off value for a designation of frailty was 6 (P=0.0014). Conclusion Frailty is a novel independent factor that can be used to predict the clinical response to CRT in the elderly population. Modifying the level of recognition in the Tilburg Frailty Indicator can improve the prediction of a response to CRT.
KIF15 promotes bladder cancer proliferation via the MEK–ERK signaling pathway

Background Bladder cancer (BC) is the most common cancer of the urinary tract and invariably predicts a poor prognosis. In this study, we found a reliable gene signature and potential biomarker for predicting clinical prognosis. Methods The gene expression profiles were obtained from the GEO database. By performing GEO2R analysis, numerous differentially expressed genes (DEGs) were found. Three different microarray datasets were integrated in order to more precisely identify up-expression genes. Functional analysis revealed that these genes were mainly involved in cell cycle, DNA replication and metabolic pathways. Results Based on protein-protein interactome (PPI) networks that were identified in the current study and previous studies, we focused on KIF15 for further study. The results showed that KIF15 promotes BC cell proliferation via the MEK -ERK pathway, and Kaplan‐Meier survival analysis revealed that KIF15 expression was an independent prognostic risk factor in BC patients. Conclusion KIF15 may represent a promising prognostic biomarker and a potential therapeutic option for BC.
Transmission of Respiratory Syncytial Virus Among Children Under 5 Years in Households of Rural Communities, the Philippines

Abstract Background To develop a more effective vaccination strategy for reducing the impact of respiratory syncytial virus (RSV) infection, especially in young infants (<6 months old), it is necessary to understand the transmission dynamics of RSV. Methods We conducted a community-based prospective cohort study from 2014 to 2016 in Biliran Province, the Philippines, on children <5 years old. We collected nasopharyngeal swabs from symptomatic children with acute respiratory infection (ARI) during household visits and at health facilities. In households (n = 181) with RSV-positive ARI cases (RSV-ARI), we also identified ARI episodes among other children <5 years old in the same household. In addition, we determined the serial interval to estimate the basic reproduction number (R0), the average number of secondary cases generated by a single primary case. Results In the 181 households analyzed, we found 212 RSV-ARI in 152 households with a single case and 29 households with multiple cases, which included 29 1st RSV-ARI and 31 2nd RSV-ARI. We also found possible index cases among children <5 years old in the same household for 29.0% (18 of 62) of young infants with RSV-ARI. The estimated mean serial interval was 3.2 days, and R0 was estimated to be 0.92–1.33 for RSV-A and 1.04–1.76 for RSV-B, which varied between different times (2014 and 2015) and places. Conclusions Young infants are likely to acquire RSV infection from older children in the same household. Therefore, vaccination targeting older children might protect infants from RSV infection.
Expression of total and phospho 4EBP1 in metastatic and non-metastatic renal cell carcinoma

Eukaryotic translation initiation factor 4E-binding protein 1 (4EBP1) is phosphorylated and activated by mammalian target of rapamycin complex 1, which serves as a regulator of cell growth, cell survival, metastasis and angiogenesis in many types of cancer. The aim of this study was to evaluate the role of phosphorylated 4EBP1 (p4EBP1) in primary renal cell carcinoma (RCC) as a biomarker in metastatic RCC (mRCC) and non-mRCC cohorts. Primary tumor tissue from 254 non-mRCC and 60 mRCC patients were immunohistochemically stained for t4EBP1 and p4EBP1. The disease-free interval (DFI) categorized by the expressions and clinical parameters were assessed by univariate and multivariate analysis in the non-mRCC cohort. Then, the cause-specific survival (CSS) was assessed in the mRCC cohort by the same methods as used in the non-mRCC cohort. In the non-mRCC cohort, patients with t4EBP1 expression had no RCC recurrence. Patients with p4EBP1 expression had the shorter DFI in univariate analysis (P=0.037). p4EBP1 and pT1b-4 expression levels were independent predictors for de novo metastasis. In the mRCC cohort, intermediate/poor MSKCC risk, non-clear cell RCC, and no p4EBP1 expression were correlated with poor CSS on multivariate analysis. Expression of p4EBP1 could be a predictive biomarker for de novo metastasis in non-mRCC patient cohort. By contrast, mRCC patients showing no p4EBP1 expression had shorter CSS than patients with p4EBP1 expression.
The long non-coding RNA LINC00460 predicts the prognosis and promotes the proliferation and migration of cells in bladder urothelial carcinoma

Long non-coding RNAs (lncRNAs) may serve an important role in cancer development and may also be suitable for use as prognostic biomarkers. At present, the role of lncRNAs in bladder cancer remains unclear. The present study examined the potential involvement of lncRNA LINC00460 in bladder urothelial carcinoma using data from The Caner Genome Atlas (TCGA) and cell line experiments. The results indicated that LINC00460 expression levels were increased in bladder urothelial carcinoma tissues and bladder cancer 5637 and T24 cell lines compared with corresponding normal controls (P<0.05). TCGA data indicated that LINC00460 expression was negatively correlated with a positive prognosis in patients with bladder urothelial carcinoma (P<0.05). Consistently, the downregulation of LINC00460 with short hairpin RNA significantly suppressed 5637 and T24 cell proliferation and migration. Therefore, it was suggested that strategies that target LINC00460 may be developed as novel therapeutic approaches for the treatment of bladder cancer. In addition, the expression level of androgen receptor (AR) was downregulated in bladder urothelial carcinoma tissues and exhibited a negative correlation with the expression level of LINC00460 (r=−0.43; P<0.0001), based on the data from TCGA. We hypothesized that LINC00460 may serve an oncogenic role by regulating the expression of AR.
Variability in the therapeutic response of Metformin treatment in patients with type 2 diabetes mellitus

Objective: To assess the glycemic response of metformin in patients with Type-2 Diabetes Mellitus (T2DM) as well as to see its association with reductions in BMI and GIT intolerance. Methods: This Quasi, Experimental study was conducted at Jinnah-Allama Iqbal Institute of Diabetes and Endocrinology (JAIDE) Jinnah Hospital, Lahore from 1st March 2016 to 30th September 2016. Newly diagnosed T2DM patients were given metformin for duration of three months and later on they were categorized into Responders and Non-Responders on the basis of HbA1c (A1C) reductions, which were estimated by Hemoglobin (A1C) analyzer (TD4611A TAIDoc Tech. Taiwan) through photometry. Similarly, baseline BMI and BMI after three months therapy with metformin was also recorded. Results: Among total of 200 patients, 40.5% of the patients were classified as Non-Responders whereas; 59.5% of the patients as Responders. The baseline BMI (26.09 kg/m2) was also decreased significantly after metformin therapy (25.40 kg/m2). It was found that metformin reduced the A1C in all the patients. However, the glycemic control was much better in patients with higher baseline A1C (1.13% ± 0.08) as compared to lower baseline levels (0.61% ± 0.07). Regarding GIT intolerance, 140 patients lacked the symptoms, out of which 60.7% were responders and 39.3% were non-responders. Conclusions: Metformin lead to improvement in glycemic control in 59.5% of newly diagnosed T2DM patients after taking metformin for three months but in 40.5% it did not which may be because of combined effects of various gene polymorphisms and their interaction with non-genetic factors. Metformin reduced the BMI in all the patients; however, BMI lowering activity of metformin was same regardless of its effect on HbA1C. Moreover, the signs and symptoms of GIT intolerance did not differ between the two groups.
Influence of Tattoo Ink on Hepatitis C Virus Infectiousness

Abstract Hepatitis C virus (HCV) is a blood-borne virus and is most frequently transmitted through large or repeated direct percutaneous exposures to infected blood. The 2 most common exposures associated with transmission of HCV are blood transfusion and intravenous drug abuse. The association between HCV transmission and other suspected risk factors such as tattooing is more controversial. Although HCV can survive for days to weeks in suspension or on inanimate surfaces, its stability in tattooing supplies remains elusive. Here, we analyzed the influence of tattoo ink on HCV infectiousness.
The development and internal validation of a model to predict functional recovery after trauma

Objective To develop and internally validate the PROgnosis of functional recovery after Trauma (PRO-Trauma) prediction model. Design A prospective single-center longitudinal cohort study. Patients were assessed at 6 weeks and 12 months post-injury. Methods Patients that presented at the emergency department with an acute traumatic injury, were prompted for participation. Patients that completed the assessments at 6 weeks and 12 months post injury were included. Exclusion criteria: age < 18, age > 65, pathologic fractures, injuries that resulted in severe neurologic deficits. The predicted outcome, functional recovery, was defined as a Short Musculoskeletal Function Assessment (SMFA-NL) Problems with Daily Activities (PDA) subscale ≤ 12.2 points at 12 months post-injury (Dutch population norm). Predictors were: gender, age, living with partner, number of chronic health conditions, SMFA-NL PDA score 6 weeks post-injury, ICU admission, length of stay in hospital, injury severity score, occurrence of complications and treatment type. All predictors were obtained before 6 weeks post-injury. Missing data were multiply imputed. Predictor variables were selected using backward stepwise multivariable logistic regression. Hosmer-Lemeshow tests were used to evaluate calibration. Bootstrap resampling was used to internally validate the final model. Results A total of 246 patients were included, of which 104 (44%) showed functional recovery. The predictors in the final PRO-Trauma model were: living with partner, the number of chronic health conditions, SMFA-NL PDA subscale score at 6 weeks post-injury and length of stay in hospital. The apparent R2 was 0.33 [0.33;0.34], the c-statistic was 0.79 [0.79;0.80]. Hosmer-Lemeshow test indicated good calibration (p = 0.92). Optimism-corrected R2 was 0.28 [0.27;0.29] and the optimism-corrected Area Under the Curve was 0.77 [0.77;0.77]. Conclusion The PRO-Trauma prediction model can be used to obtain valid predictions of attaining functional recovery after trauma at 12 months post-injury. The PRO-Trauma prediction model showed acceptable calibration and discrimination.
Auditory Localization and Spatial Release From Masking in Children With Suspected Auditory Processing Disorder.

OBJECTIVES We sought to investigate whether children referred to our audiology clinic with a complaint of listening difficulty, that is, suspected of auditory processing disorder (APD), have difficulties localizing sounds in noise and whether they have reduced benefit from spatial release from masking. DESIGN Forty-seven typically hearing children in the age range of 7 to 17 years took part in the study. Twenty-one typically developing (TD) children served as controls, and the other 26 children, referred to our audiology clinic with listening problems, were the study group: suspected APD (sAPD). The ability to localize a speech target (the word "baseball") was measured in quiet, broadband noise, and speech-babble in a hemi-anechoic chamber. Participants stood at the center of a loudspeaker array that delivered the target in a diffused noise-field created by presenting independent noise from four loudspeakers spaced 90° apart starting at 45°. In the noise conditions, the signal-to-noise ratio was varied between -12 and 0 dB in 6-dB steps by keeping the noise level constant at 66 dB SPL and varying the target level. Localization ability was indexed by two metrics, one assessing variability in lateral plane [lateral scatter (Lscat)] and the other accuracy in the front/back dimension [front/back percent correct (FBpc)]. Spatial release from masking (SRM) was measured using a modified version of the Hearing in Noise Test (HINT). In this HINT paradigm, speech targets were always presented from the loudspeaker at 0°, and a single noise source was presented either at 0°, 90°, or 270° at 65 dB A. The SRM was calculated as the difference between the 50% correct HINT speech reception threshold obtained when both speech and noise were collocated at 0° and when the noise was presented at either 90° or 270°. RESULTS As expected, in both groups, localization in noise improved as a function of signal-to-noise ratio. Broadband noise caused significantly larger disruption in FBpc than in Lscat when compared with speech babble. There were, however, no group effects or group interactions, suggesting that the children in the sAPD group did not differ significantly from TD children in either localization metric (Lscat and FBpc). While a significant SRM was observed in both groups, there were no group effects or group interactions. Collectively, the data suggest that children in the sAPD group did not differ significantly from the TD group for either binaural measure investigated in the study. CONCLUSIONS As is evident from a few poor performers, some children with listening difficulties may have difficulty in localizing sounds and may not benefit from spatial separation of speech and noise. However, the heterogeneity in APD and the variability in our data do not support the notion that localization is a global APD problem. Future studies that employ a case study design might provide more insights.
Prefabricated and Self-Setting Cement Laminates

Polycaprolactone (PCL) fiber mats with defined pore architecture were shown to provide sufficient support for a premixed calcium phosphate cement (CPC) paste to serve as a flat and flexible composite material for the potential application in 2-dimensional, curved cranial defects. Fiber mats were fabricated by either melt electrospinning writing (MEW) or solution electrospinning (SES) with a patterned collector. While MEW processed fiber mats led to a deterioration of the cement bending strength by approximately 50%, due to a low fiber volume content in conjunction with a weak fiber-matrix interface, fiber mats obtained by solution electrospinning resulted in a mechanical reinforcement of the cement matrix in terms of both bending strength and absorbed fracture energy. This was attributed to a higher fiber volume content and a large contact area between nanosized fibers and cement matrix. Hydrophilization of the PCL scaffolds prior to lamination further improved composite strength and preserved the comparably higher fracture energy of 1.5 to 2.0 mJ/mm2. The laminate composite approach from this study was successful in demonstrating the limitations and design options of such novel composite materials. However, fiber-cement compatibility remains an issue to be addressed, since a high degree of hydrophilicity does not necessarily provoke a stronger interface.
