Comparative effects of mature coconut water (Cocos nucifera) and glibenclamide on some biochemical parameters in alloxan induced diabetic rats
P. P. Preetha,V. Girija Devi,T. Rajamohan
Revista Brasileira de Farmacognosia , 2013,
Abstract: In the present study, comparative effects of mature coconut water (Cocos nucifera L., Arecaceae) and glibenclamide in alloxan induced diabetic rats were evaluated. Diabetes mellitus was induced in Sprague-Dawly rats using alloxan monohydrate (150 mg kg-1 body weight). Treatment with lyophilized form of mature coconut water and glibenclamide in diabetic rats reduced the blood glucose and glycated hemoglobin along with improvement in plasma insulin level. Elevated levels of liver function enzymes markers like alkaline phosphatase, serum glutamate oxaloacetate transaminase and serum glutamate pyruvate transaminase in diabetic rats were significantly reduced on treatment with mature coconut water. In addition to this, diabetic rats showed altered levels of blood urea, serum creatinine, albumin, albumin/globulin ratio which were significantly improved by treatment with mature coconut water and glibenclamide. Activities of nitric oxide synthase in liver and plasma L-arginine were reduced significantly in alloxan induced diabetic rats while treatment with mature coconut water reversed these changes. The overall results show that mature coconut water has significant beneficial effects in diabetic rats and its effects were comparable to that of glibenclamide, a well known antidiabetic drug.
Menstruating from the umbilicus as a rare case of primary umbilical endometriosis: a case report
Pallavi V Bagade, Mamdouh M Guirguis
Journal of Medical Case Reports , 2009, DOI: 10.1186/1752-1947-3-9326
Abstract: A 35-year-old Caucasian woman presented with umbilical bleeding during periods of menstruation. Her umbilicus had a small nodule with bloody discharge. An ultrasound was performed and a diagnosis of possible umbilical endometriosis was thus made. The nodule shrunk in response to gonadotropin-releasing hormone analogues but continued to persist. The patient underwent a wide local excision of the nodule with a corresponding umbilical reconstruction. Histopathology confirmed the diagnosis of umbilical endometriosis. The patient was asymptomatic at follow-up, but nevertheless warned of the risk of recurrence.Pelvic endometriosis is a common condition, but the diagnosis of primary umbilical endometriosis is difficult and differentials should be considered. This case strongly suggests that a differential diagnosis of endometriosis should be considered when an umbilical swelling presents in a woman of reproductive age.Endometriosis, a term first used by Sampson, is the presence of endometrial glands and stroma outside the uterine cavity and musculature [1]. It affects 7% to 10% of women in the reproductive age group [2]. It commonly occurs in the pelvic organs, especially the ovaries, the uterosacral ligaments and the pouch of Douglas. Women with endometriosis often present with dysmenorrhea, menorrhagia, pelvic pain and infertility.Extragenital endometriosis is less common, but has been described in almost every area of the female body including the bowel, bladder, lungs, brain, umbilicus, and surgical scars [3]. Due to its varied presentations, endometriosis remains a difficult condition to diagnose and treat.Umbilical endometriosis represents 0.5% to 1% of all cases of extragenital endometriosis. It usually occurs secondary to surgical scars, but very rarely presents as primary umbilical endometriosis [4,5]. We report one such rare case of spontaneous, primary umbilical endometriosis.A 35-year-old Caucasian parous woman presented to the clinic with symptoms of spontaneo
Design of a High Speed FPGA-Based Classifier for Efficient Packet Classification
Pallavi. V. S,Dr. Rukmani Devi. D
Computer Science , 2014, DOI: 10.14445/22312803/IJCTT-V9P126
Abstract: Packet classification is a vital and complicated task as the processing of packets should be done at a specified line speed. In order to classify a packet as belonging to a particular flow or set of flows, network nodes must perform a search over a set of filters using multiple fields of the packet as the search key. Hence the matching of packets should be much faster and simpler for quick processing and classification. A hardware accelerator or a classifier has been proposed here using a modified version of the HyperCuts packet classification algorithm. A new pre-cutting process has been implemented to reduce the memory size to fit in an FPGA. This classifier can classify packets with high speed and with a power consumption factor of less than 3W. This methodology removes the need for floating point division to be performed by replacing the region compaction scheme of HyperCuts by pre-cutting, while classifying the packets and concentrates on classifying the packets at the core of the network.
Tobacco control in India

Indian Journal of Dental Research , 2007,
Abstract: Portuguese introduced tobacco to India 400 years ago. Ever since, Indians have used tobacco in various forms. Sixty five per cent of all men and 33% of all women use tobacco in some form. Tobacco causes over 20 categories of fatal and disabling diseases including oral cancer. By 2020 it is predicted that tobacco will account for 13% of all deaths in India. A major step has to be taken to control what the World Health Organization, has labeled a ′smoking epidemic′ in developing countries. India′s anti-tobacco legislation, first passed in 1975, was largely limited to health warnings and proved to be insufficient. A new piece of national legislation, proposed in 2001, represents an advance including banning smoking in public places, advertising and forbidding sale of tobacco to minors. Preventing the use of tobacco in various forms as well as treating nicotine addiction is the major concern of dentists and physicians. The dental encounter probably constitutes a "teachable moment" when the patient is receptive to counseling about life- style issues. Both policy makers and health professionals must work together for achieving a smoke free society for our coming generations.
Modeling and Detection of Camouflaging Worm using IP Traceback
S Preetha
International Journal of Computer Science and Communication Networks , 2012,
Abstract: Active worms pose major security threats to the Internet. This is due to the ability of active worms to propagate in an automated fashion as they continuously compromise computers on the Internet. Active worms evolve during their propagation, and thus, pose great challenges to defend against them. A new class of active worms, referred to as Camouflaging Worm (C-Worm in short). The C-Worm is different from traditional worms because of its ability to intelligently manipulate its scan traffic volume over time. Thereby, the C-Worm camouflages its propagation from existing worm detection systems based on analyzing the propagation traffic generated by worms. The characteristics of the C-Worm and conduct a comprehensive comparison between its traffic and non-worm traffic (background traffic). The two types of traffic are barely distinguishable in the time domain. However, their distinction is clear in the frequency domain, due to the recurring manipulative nature of the C-Worm. Motivated by observations, designed a novel spectrum-based scheme to detect the C-Worm. The Power Spectral Density (PSD) distribution of the scan traffic volume and its corresponding Spectral Flatness Measure (SFM) to distinguish the C-Worm traffic from background traffic. Using a comprehensive set of detection metrics and real-world traces as background traffic, the extensive performance evaluations on proposed spectrum-based detection scheme. The performance data clearly demonstrates that our scheme can effectively detect the C-Worm propagation. Furthermore, show the generality of spectrum-based scheme in effectively detecting not only y the C-Worm, but traditional worms as well

Journal of the Indian Society of Pedodontics and Preventive Dentistry , 2007,
Abstract: Occlusal pits and fissures are the most susceptible sites for the development of dental caries and prevention is difficult in the areas of occurrence. Although only 12.5% of all the tooth surfaces are occlusal, these surfaces develop more than two-thirds of total caries experienced by children. The fate of the bacteria is of significance when they are inadvertently sealed by a dental sealant. This study aimed in examining the antibacterial properties of three commercially available sealants, viz., Teethmate-F, Helioseal-F and Helioseal. Antibacterial testing was done by disc diffusion method. Selective agars were used to grow Streptococcus mutans and Lactobacillus acidophilus, which are implicated in the pathogenesis of dental caries. Statistical analysis was carried out using student′s t test. The study proved that Helioseal-F and Helioseal did not possess antibacterial properties and Teethmate-F was the only sealant that showed antibacterial properties.

Abstract: The main aim of this study is to develop ocular drug delivery system for Natamycin; a polyene antibiotic is highly useful for the treatment of conjunctivitis and keratitis. The ocuserts were prepared using different polymers such as eudragit L-100, eudragit S-100, eudragit RL-100, hydroxy propyl methyl cellulose phthalate and cellulose acetate phthalate at various proportion and combinations using PEG-400 as plasticizer. The prepared ocuserts were evaluated for their physicochemical parameters like drug content, weight uniformity, folding endurance, thickness, % moisture absorption and water vapour transmission rate. The in vitro drug release from the formulations was studied using commercial semi permeable membrane and the in vitro release kinetic datas were treated according to the diffusion models proposed by Higuchi and Peppas in order to access the mechanism of drug release from the formulations, which were following zero order kinetics. All the formulations showed no change in the physical appearance and the FTIR studies indicated no possibility of interaction between drug and polymer. The expected zero order release for one day was observed in the formulation D1 (3% Eudragit RL100 and 1% Eudragit L100) Keywords: Ocular Insert; Ocular Delivery; Natamycin DOI: 10.3126/kuset.v6i1.3318 Kathmandu University Journal of Science, Engineering and Technology Vol.6(1) 2010, pp108-115

Abstract: Mammalian sex hormones are spread in the environment from natural and anthropogenic sources. In the present study, the effect of estradiol on Arabidopsis thaliana growth primary metabolism, phenylpropanoid and flavonoid pathways and pathogen resistance were investigated. Treatments of Arabidopsis plants with 10 and 100 nM 17β-estradiol resulted in enhanced root growth and shoot biomass. In addition, treated plants had an increased rate of photosynthesis with a concomitant increase in carbohydrate and protein accumulation. Plants exposed to higher concentrations of 17β-estradiol (10 μM) had significantly lower root growth, biomass, photosynthesis rate, primary metabolite and phenylpropanoid and flavonoid contents indicating a toxic effect of estradiol. Treatments with increasing estradiol concentrations (10 nM, 100 nM and 10 μM) resulted in the downregulation of phenylpropanoid-flavonoid pathway genes (PAL1, PAL4, CHI and ANS) and subsequent decreased accumulation of phenolics, flavonoids and anthocyanins. Estradiol-treated plants were inoculated with Pseudomonas syringae pv. Tomato DC3000 and basal resistance was determined. Estradiol treatments rendered plants susceptible to the pathogen, thus compromising the plant defense mechanisms. These results indicate that at low concentrations, estradiol functions as a biostimulant of growth, yield and primary metabolism of Arabidopsis. However, estradiol functions as a potential transcriptional regulator of the phenylpropanoid pathway genes in Arabidopsis, having a negative effect on
