    Network attacks are discovered using intrusion detection systems (IDS), one of the most crucial security solutions. Machine learning techniques-based intrusion detection approaches have been rapidly created as a result of the widespread use of standard machine learning algorithms in the security field. Unfortunately, as technology has advanced and there have been faults in the machine learning-based intrusion detection system, the system has consistently failed to fulfill the standards for cyber security. Generative adversarial networks (GANs) have drawn a lot of interest recently and have been utilized widely in anomaly detection due to their enormous capacity for learning difficult high-dimensional real time data distribution. Traditional machine learning algorithms for intrusion detection have a number of drawbacks that deep learning techniques can significantly mitigate. With the help of a real time dataset, this work suggests employing GANs and its variants to detect network intrusions in SDN. The feasibility and comparison results are also presented. For different kinds of datasets, the BiGAN outcomes outperform the GAN

    AbstractWe describe a series of 18 cases of abdominal cocoon in patients presenting with features of small intestinal obstruction or perforative peritonitis, nine of whom had tubercular aetiology while the rest were idiopathic. Manifestations of abdominal tuberculosis such as mesenteric abscesses, enlarged and caseating mesenteric lymph nodes, and tubercles over the bowel serosa were found in only 55% patients who were ultimately diagnosed to have Tubercular aetiology. We conclude that a high index of suspicion for this rare cause of a common surgical emergency is desirable

    Dynamic Response of Heterogeneity and Reinforcement on the Propagation of Torsional Surface Waves

    This paper aims to investigate the effect of reinforcement and heterogeneity on the propagation of torsional surface waves. Geometry of the problem is consists of heterogeneous fibre-reinforced layer lying over a heterogeneous isotropic half-space. Heterogeneity in the layer is caused due to exponential variation of elastic parameters whereas quadratic variation in elastic parameters is considered for half-space. Dispersion relation for torsional surface waves has been obtained and matched with classical Love wave equation by taking an isotropic homogeneous layer lying over an isotropic homogeneous half-space. Some existing results have been deduced as particular case of the present study. Velocity profile of surface waves is compared for both, reinforced and reinforced free cases. Numerical examples have been discussed by taking steel fibre-reinforced material. Graphical representation has been made to exhibit the findings

    EFFECT OF BLUMEA LACERA ON TISSUE GSH, LIPID PEROXIDATION AND HEPATIC CELLS IN ETHANOL INDUCED HEPATOTOXICITY IN RATS

    Objective: To evaluate hepatoprotective effects of ethanol extract of aerial part of Blumea lacera (BLEE) against ethanol-induced hepatotoxicity in rats. Methods: The in vivo antioxidant activity of BLEE was assessed by determining the tissue glutathione (GSH) and lipid peroxidation (LPO) levels. The BLEE at the doses of 200 and 400 mg/kg and silymarin 100 mg/kg administered to the ethanol challenged rats. The effects of BLEE and silymarin on Physical and Biochemical Parameters were measured. Similarly, histopathological changes of the liver were studied. Results: The BLEE showed in vivo antioxidant activity. A significant (P<0.001) decrease in SGOT, SGPT, ALP, total and direct bilirubin was observed in BLEE treated group at doses i.e. 200 mg/kg and 400 mg/kg as compared to intoxicated group. Liver damage in animal pretreated with BLEE was minimal with distinct preservation of structures and the architectural frame of the hepatic cells. Conclusion: These findings demonstrated the hepatoprotective effects of BLEE against ethanol-induced liver damage

    Sixth cervical vertebra with bilateral double foramen transversarium and non-bifid spine: a rare case

    Get PDF
    Anatomical knowledge of variations is of utmost clinical importance to all of us as they may be one of the reasons as etiological as well as of surgical importance. Vertebral region also presents many variations. Foramen transversarium are typical feature of cervical vertebrae and give way to neurovascular bundle, like vertebral artery, vertebral veins and sympathetic plexus around them throughout. Foramen transversarium and spine or spinous process of cervical vertebrae are important to all of medical specialists as well as for surgeons specially the surgeons dealing with head & neck surgeries. Knowledge of anatomical/surgical variations is very important for neurosurgeons and radiologists for reporting and planning for surgeries as this type of variation if ignored may be a cause for fatal or undesirable outcome of the surgical procedure or may lead to a different planning/approach at the time or during the surgical procedure. In the present case we observed very uncommon finding of bilateral double foramen transversarium as well as a nonbifid spinous process in sixth cervical vertebra which is extremely rare. Right and left both main foramen transversarium were bilateral symmetrical and rounded in shape. Right accessory foramen transversarium was complete while left was incomplete. Finding of present study is important in neurosurgery for posterior approaches of the cervical vertebrae and also useful for radiological studies to avoid erroneous counting of cervical spines in clinical observations as surface landmark

    Objectives: The objective of the present work is to study the in vivo anti-oxidant and hepatoprotective effects of Hugonia mystax in paracetamol (PCM)induced hepatotoxicity in rats.Methods: The in vivo anti-oxidant activity of 70% ethanol extract of leaves of H. mystax (HMEE) was assessed by determining the tissue glutathioneand lipid peroxidation (LPO) levels. HMEE 200 and 400 mg/kg p.o. doses and silymarin p.o.100 mg/kg were administered to the PCM challengedrats. The effect of HMEE and silymarin on physical (liver weight and liver volume) and biochemical parameters (serum enzymes [serum glutamicoxaloacetic transaminase (SGOT) and serum glutamate-pyruvate transaminase (SGPT)], alkaline phosphate [ALP], and bilirubin) were measured.Furthermore, histopathological changes in the liver were studied.Results: The HMEE showed in the vivo anti-oxidant activity. Pre-treatment with HMEE for 7 days significantly reduced the elevated biochemicalparameters (SGOT, SGPT, ALP, and bilirubin levels). The hepatic damage in animal pretreated with HMEE was minimal with distinct preservation ofstructures and architectural frame of the hepatic cells.Conclusion: These findings demonstrate the protective nature of HMEE against PCMKeywords: Hugonia mystax, Hepatoprotective, In vivo anti-oxidant, Paracetamol

    Feasibility of breast crawl in a tertiary care teaching institute

    Get PDF
    Background: Early initiation of breastfeeding has many beneficial effects for both the mother and the baby. The breast crawl has been established as the ideal method for promoting early skin-to-skin contact and early initiation of breastfeeding. Objective: The objective of the study was to assess the feasibility of breast crawl in a busy tertiary care institute. Materials and Methods: An observational study was performed including 50 mother-baby pairs, admitted to the labor room of Sassoon General Hospital, Pune, from January2018 for 6 months. Observations were made on patient and nurse attitude and behavior and were further analyzed. Results: Of the total subjects, 23 (46%) mothers had not received any counseling about breastfeeding during the antenatal period and none of them were familiar with the idea of breast crawl from the antenatal period. Of the 50 mothers, 27 mothers (54%) were concerned about privacy, 8 (16%) were concerned about environmental cold, 6 (12%) were worried about exposure, and 9 mothers (18%) were concerned about the baby, whereas 6 mothers (12%) had no concerns and 6 mothers had more than one concern. The attitude of the nursing staff was favorable (enthusiastic) 19 times, indifferent 23 times, reluctant 6 times, and unfavorable (uncooperative) 2 times. Conclusion: While it is highly desirable to implement breast crawl as a routine practice, there are several roadblocks such as lack of antenatal counseling, lack of awareness and motivation, lack of specific guidelines and instructions, skewed staff-to-patient and bed-to-patient ratio, and lack of privacy
