    Background: Haemorrhoids are dilated veins occurring in relation to the anus. There are various treatment modalities for haemorrhoids and among them surgical treatment is considered to be most effective one. Harmonic scalpel hemorrhoidectomy was compared with conventional in terms of symptomatic relief and complications.Methods: The aim of our study was to compare harmonic scalpel haemorrhoidectomy with conventional in terms of various intraoperative and postoperative factors for the treatment of grade III and IV haemorrhoids.Results: In our case study of 25 patients average time taken was 17.68 ± 2.84 minutes, while it was 28.44 ±3.69 minutes in control group. The mean blood loss was 8.96 ± 2.15 ml, 31.72 ± 3.28 ml in the case and control group respectively. Postoperative pain with VAS in case group on the first postoperative day was 5.92 ± 0.72, while it was 8.52 ± 0 in the control group. The dose of analgesia was less in case group. The postoperative wound site soakage was less in case study, early ambulation and return to normal work was faster in case study group.Conclusions: Harmonic scalpel haemorrhoidectomy is a simple, bloodless, safe and effective procedure in terms of blood loss, postoperative pain early return to routine work because of less lateral thermal injury

    A New Ensemble-Based Intrusion Detection System for Internet of Things

    The domain of Internet of Things (IoT) has witnessed immense adaptability over the last few years by drastically transforming human lives to automate their ordinary daily tasks. This is achieved by interconnecting heterogeneous physical devices with different functionalities. Consequently, the rate of cyber threats has also been raised with the expansion of IoT networks which puts data integrity and stability on stake. In order to secure data from misuse and unusual attempts, several intrusion detection systems (IDSs) have been proposed to detect the malicious activities on the basis of predefined attack patterns. The rapid increase in such kind of attacks requires improvements in the existing IDS. Machine learning has become the key solution to improve intrusion detection systems. In this study, an ensemble-based intrusion detection model has been proposed. In the proposed model, logistic regression, naive Bayes, and decision tree have been deployed with voting classifier after analyzing model’s performance with some prominent existing state-of-the-art techniques. Moreover, the effectiveness of the proposed model has been analyzed using CICIDS2017 dataset. The results illustrate significant improvement in terms of accuracy as compared to existing models in terms of both binary and multi-class classification scenarios

    Adjuvant bevacizumab for melanoma patients at high risk of recurrence: survival analysis of the AVAST-M trial

    Background: Bevacizumab is a recombinant humanised monoclonal antibody to vascular endothelial growth factor shown to improve survival in advanced solid cancers. We evaluated the role of adjuvant bevacizumab in melanoma patients at high risk of recurrence. Patients and methods: Patients with resected AJCC stage IIB, IIC and III cutaneous melanoma were randomised to receive either adjuvant bevacizumab (7.5?mg/kg i.v. 3 weekly for 1?year) or standard observation. The primary end point was detection of an 8% difference in 5-year overall survival (OS) rate; secondary end points included disease-free interval (DFI) and distant metastasis-free interval (DMFI). Tumour and blood were analysed for prognostic and predictive markers. Results: Patients (n=1343) recruited between 2007 and 2012 were predominantly stage III (73%), with median age 56?years (range 18-88?years). With 6.4-year median follow-up, 515 (38%) patients had died [254 (38%) bevacizumab; 261 (39%) observation]; 707 (53%) patients had disease recurrence [336 (50%) bevacizumab, 371 (55%) observation]. OS at 5?years was 64% for both groups [hazard ratio (HR) 0.98; 95% confidence interval (CI) 0.82-1.16, P?=?0.78). At 5?years, 51% were disease free on bevacizumab versus 45% on observation (HR 0.85; 95% CI 0.74-0.99, P?=?0.03), 58% were distant metastasis free on bevacizumab versus 54% on observation (HR 0.91; 95% CI 0.78-1.07, P?=?0.25). Forty four percent of 682 melanomas assessed had a BRAFV600 mutation. In the observation arm, BRAF mutant patients had a trend towards poorer OS compared with BRAF wild-type patients (P?=?0.06). BRAF mutation positivity trended towards better OS with bevacizumab (P?=?0.21). Conclusions: Adjuvant bevacizumab after resection of high-risk melanoma improves DFI, but not OS. BRAF mutation status may predict for poorer OS untreated and potential benefit from bevacizumab. Clinical Trial Information: ISRCTN 81261306; EudraCT Number: 2006-005505-64

    Development and validation of an HPLC-UV method for accelerated stability study and pharmacokinetic analysis of venlafaxine

    A reverse phase high performance liquid chromatography method has been developed and validated for accelerated stability study and determination of pharmacokinetic parameters of venlafaxine HCl. The chromatographic separation was carried out using ODS analytical column (250 × 4.6 mm i.d., 5 μm particle size). The mobile phase included acetonitrile, methanol and potassium dihydrogen phosphate buffer (30:30:40; pH 6.1) at a flow rate 1.5 mL min−1. UV-Visible detector was used at wavelength of 227 nm to monitor elutions. Retention time observed was 2.745 min. The method was validated for linearity, accuracy, precision, sensitivity and robustness. Accelerated stability study of venlafaxine HCl capsules was carried out at 40 and 50 °C under 75% RH level. Suggested method was successfully applied for the pharmacokinetic analysis of venlafaxine hydrochloride tablets. Each of ten albino rabbits (≈ 1.2 kg each) was orally administered with 5 mg dose of venlafaxine HCl. The method was proved to be linear (R2 >0.998), accurate (98.25-99.27%), sensitive (LOD: 35ngmL−1; LOQ: 105 ng mL−1) and robust (RSD<1%). The drug showed stability at accelerated conditions of temperature and humidity. The main pharmacokinetic parameters of tested products were as follows: tmax was 2.5h, Cmax was 56.5 μg mL−1, t1/2 was 8.2 h, AUC0-36 was 845.9 μg h mL−1. The developed method is suitable to apply for quality control analysis and pharmacokinetic studies

    We report on the measurement of freeze-out radii for pairs of identical-charge pions measured in Pb-Pb collisions at √sNN = 2.76 TeV as a function of collision centrality and the average transverse momentum of the pair kT. Three-dimensional sizes of the system (femtoscopic radii), as well as direction-averaged onedimensional radii are extracted. The radii decrease with kT, following a power-law behavior. This is qualitatively consistent with expectations from a collectively expanding system, produced in hydrodynamic calculations. The radii also scale linearly with _dNch/dη_1/3. This behavior is compared to world data on femtoscopic radii in heavy-ion collisions. While the dependence is qualitatively similar to results at smaller √sNN, a decrease in the ratio Rout/Rside is seen, which is in qualitative agreement with a specific prediction from hydrodynamic models: a change from inside-out to outside-in freeze-out configuration. The results provide further evidence for the production of a collective, strongly coupled system in heavy-ion collisions at the CERN Large Hadron Collider
