A Brief study on Steganography techniques

As there is a lot of advancement in the field of internet or communication technology, we have various means of storing, accessing and distribution of the data in the digital format. Due to the rapid advancement in this field has also introduced many challenges to the researchers to provide security to the information which is transmitted over the network. The digital information circulating over the network also includes the medical information. In order to provide security, confidentiality and integrity, the steganographic techniques can be employed. In the section 1, it gives the introduction about available hiding techniques; the section 2 explains the various steganography properties, the section 3 gives the types of steganographic techniques, the section 4 gives the applications of steganography, the section 5 gives the quality parameters to be measured for medical information, and the section 6 gives the steganographic algorithms available. Finally the section 7 concludes that to prevent unauthorized access steganography is the suitable technique

Ensemble Machine Learning Model to Predict Benefaction of an Individual in the Health Sector

Ensemble methodis a machine learning technique that combines several base models in order to produce one optimal predictive model. This work aims to develop blood donor’s prediction model, for the management of the blood bank during emergency situations using ensemble method. The proposed model uses two supervised algorithms including multivariate regression and decision tree algorithms. An automated intelligent system is developed that learns from the data presented to the machine learning model to predict blood donors. The system is integrated with score allocation to the blood donors. A network of available ethical blood donors’ model has been developed which can be used in case of an emergency for an ailing person. Machine Learning techniques are used to find a perfect matched donor with respect to blood group, medical history and other demographics. A prioritized/ranked donor list based on their medical history, habits and other blood related metrics is generated to benefit the receivers. The ensemble methods used in this intelligent system helps in report generation facilitating medical experts and the society in decision making leading to increased number of donors

CLINICAL EVALUATION OF HERBAL COMPOUND DRUGS IN THE MANAGEMENT OF LEIOMYOMA INDUCED MENORRHAGIA

Leiomyoma is very commonly seen in the present times in Gynecological practice. The incidence is high in women in active reproductive age, especially in nulliparous women. These are commonly known as Fibroids and are composed of fibrous connective tissue. The majority of the small Leiomyomas and some large ones are asymptomatic. Fibroid which are near to endometrial cavity, can cause symptoms like menorrhagia, low-back pain, lower abdomen pain etc. Based on the clinical features this tumour can be compared with the Mamsajarbuda type of Arbuda, described in Ayurvedic classics. There is no established treatment to control the Menorrhagia induced by Fibroid Uterus. Hence the present study is taken up to evaluate the efficacy of compound formulations viz., Ashokarishtam and Lodhrasava in controlling excessive bleeding during menses. Study carried out on 30 number of patients, of which, 14 (46.67%) had shown Good response, 03 (10.00%) had shown Fair response, 06 (20.00%) had shown Poor response, and 07 (23.33%) cases did not show any response. On statistical analysis of overall parameters adopted for the study, it is found that the drug efficacy in controlling menorrhagia was highly significant (P<0.001)

Some results on the distance r-b-coloring in graphs

Given a positive integer r, two vertices u, v ∈ V (G) are r- independent if d(u, v) > r. A partition of V (G) into r-independent sets is called a distance r-coloring. A study of distance r-coloring and distance r-b-coloring concepts are studied in this paper.Publisher's Versio

Study to evaluate the effectiveness of coagulation factor concentrate prophylaxis in children with severe hemophilia

Objective: To evaluate the effectiveness of prophylaxis with coagulation factor concentrates VIII/IX (FVII/IX) in children with severe hemophilia A/B, respectively. Materials and Methods: Retrospective observational study was done on children enrolled in our hemophilia clinic, who initially received “on demand” therapy and were on prophylaxis with factor VIII/IX concentrate at the time of the study. The study group consisted of 8 children. Annual hemarthrosis rate (AHR) over a period of 1-year during on demand therapy was compared with AHR during a period of 1-year on prophylaxis with FVIII/IX. Results: There was reduction in AHR by 87% in hemophilia A and 85% in hemophilia B during prophylaxis compared to on demand therapy. There was a significant reduction in hemarthrosis/patient/year from 2.5 to 0.3 on prophylaxis with factor concentrate compared to on demand therapy. There was also reduction in other bleeding manifestation like psoas muscle bleed, oral bleeds, epistaxis, and number of target joints involved. Conclusion: Prophylaxis with coagulation factor concentrate significantly reduces the AHR, and hence, decreases the disability associated with it compared to “on demand” therapy

Stereospecific synthesis and enzyme studies of CDP-diacylglycerols

The fatty acid specificity of two enzymes that metabolize CDPdiacylglycerol, CDPdiacylglycerol hydrolase (EC 3.6.1.26) and CDPdiacylglycerol:inositol phosphatidyltransferase (EC 2.7.8.11), has been examined in guinea pig brain. Mixed CDPdiacylglycerols were stereospecifically synthesized by the following sequence: (i) hydrolysis of a homodiacyl lecithin to 1-acyl lysoPC by action of snake venom phospholipase A2, (ii) reacylation with the anhydride of the desired second fatty acid and dimethylaminopyridine, (iii) hydrolysis of the resultant heterodiacyl lecithin to phosphatidate with cabbage phospholipase D, and (iv) reaction of phosphatidate with CMPmorpholidate to give CDPdiacylglycerol. CDPdiacylglycerol:inositol phosphatidyltransferase showed the following rates of conversion of 40-[mu]M suspensions of CDPdiacylglycerol in 0.15% Triton X-100 to phosphatidylinositol relative to the 1-stearoyl-2-oleoyl derivative (100%): dipalmitoyl, 70%; distearoyl, 38%; diarachidonoyl, 9%; 1-arachidonoyl-2-stearoyl, 6%; 1-stearoyl-2-arachidonoyl, 4%. These results indicate that the composition of isolated phosphatidylinositol and related lipids is not explained by the fatty acid specificity of the biosynthetic enzymes and supports the intervention of a deacylation-reacylation sequence. The rates of hydrolysis of the synthetic CDPdiacylglycerols at 76 [mu] M, in 0.3% Triton X-100, by the CDPdiacylglycerol hydrolase relative to the 1-stearoyl-2-oleoyl derivative (100%) were: dipalmitoyl, 70%; distearoyl, 32%; 1-arachidonoyl-2-stearoyl, 30%; 1-stearoyl-2-arachidonoyl, 28%; diarachidonoyl, 22%. Inhibition of this enzyme by AMP was shown to be non-competitive, with a Ki of 40 [mu].M. The lysosomal localization of the mammalian hydrolase was confirmed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/23865/1/0000104.pd

Response to autotomy in anesthetized freshwater crab, Paratelphusa hydrodromous (Herbst)

To extend the knowledge of amputation and induction of autotomy, the freshwater crab Paratelphusa hydrodromous (Herbst) was chosen as a model system. Amputation of different legs of Paratelphusa hydrodromous (Herbst) was done in two conditions; normal and anesthetized crab. Autotomy of the amputated legs under normal condition was induced autotomy within seconds (1.6 to 37 seconds). However, the amputation conducted in ice cold anesthetized crab showed delayed autotomy in a wide range of time from 10.2 ± 0.83 minutes (cheliped) to 114.8 ± 4.3 minutes (2nd walking leg). The observations suggest that ice cold anesthesia lowers the signaling of pain to the brain and delays autotomy, the voluntary mechanism to escape from the predator/pain or frightened force

Top Quark Physics at the Tevatron

The discovery of the top quark in 1995, by the CDF and D0 collaborations at the Fermilab Tevatron, marked the dawn of a new era in particle physics. Since then, enormous efforts have been made to study the properties of this remarkable particle, especially its mass and production cross section. In this article, we review the status of top quark physics as studied by the two collaborations using the p-pbar collider data at sqrt(s) = 1.8 TeV. The combined measurement of the top quark mass, m_t = 173.8 +- 5.0 GeV/c^2, makes it known to a fractional precision better than any other quark mass. The production cross sections are measured as sigma (t-tbar) = 7.6 -1.5 +1.8 pb by CDF and sigma (t-tbar) = 5.5 +- 1.8 pb by D0. Further investigations of t-tbar decays and future prospects are briefly discussed.Comment: 119 pages, 59 figures, 17 tables Submitted to Int. J. Mod. Phys. A Fixed some minor error
