Abstract: A multimodal biometric system combines the different biometric traits and provides better recognition performance as compared to the systems based on single biometric trait or modality. In multimodal biometric system the fusion of the information can be done at various levels, but due to the ease in combining and accessing the scores generated by different matchers, the most common approach is the integration at the matching score level. Before combining, the scores should alter into a common domain, since different matchers generate heterogeneous scores. In this paper, we have studied performance of a single fast normalized cross-correlation matcher and simple sum-rule fusion technique based on face and signature traits of a user. The experiments conducted on a database of 17 users indicate that simple sum of score fusion method results in better recognition performance than using single face or single signature based biometric system. However, experiments also reveal that the normalized cross-correlation based matcher gives better results, highlighting the need for a robust and efficient feature extraction technique.

Journal of Biological Sciences , 2007,
Abstract: This study reports on the modification and optimization of the sample preparation method for analyzing nucleotide sequence in plant species by capillary electrophoresis. The experimental study was aimed at developing possible ways of increasing the throughput of the method. The optimization conditions modified were purification of the PCR product, concentration adjustment of cycle sequencing kit BDT v3.1 from half to quarter reactions for economic analysis. Concentrations of the tamplet, primer and program of thermocycler were also optimized. Finally the volume of Hi-Di form amide was adjusted for the required sequencing. The accuracy of analysis was greater than 99.99%. The modified method enables quality sequencing results with higher average signal intensities compared to the standard recommended method. With the optimized electrophoresis conditions reported here, greater than 700 base pairs can be analyzed within 75 min using POP7. It was found that deviation from the recommended method consistently delivers higher signal-to-noise ratios and signal intensities and longer Phred20 read lengths. It is more reproducible than that of other methods and enables rapid, more cost effective robustness for nucleotide sequencing in the samples of plant origin received from research laboratory sources.

Nigerian Journal of Physiological Sciences , 2008,
Abstract: The hypoglycaemic effect of aqueous leaf extract of Murraya koenigii was studied in normal and alloxan- induced diabetic rats. The extract was administered orally at 100 mg/Kg, 150 mg/Kg and 200 mg/Kg bodyweight each to respective groups of animals (Groups I, II and III) for seven days. Group IV received normal saline and served as control for the normal rats. For the alloxan-induced diabetic rats, the same dosage pattern was administered to three groups of rats for seven days (Groups V, VI and VII) while group VIII which received normal saline served as control. At the various dose levels administered, the glucose lowering effect was more pronounced in the alloxan-diabetic rats than in control rats. When compared with chlorpropamide, the glucose lowering effect of aqueous extract of Murraya koenigii was significantly (p <0.05) lower at the dose levels administered in both normal and alloxan-diabetic rats.

Abstract: Seroma is a common problem after mastectomy, occurring in 30-92% of cases. The aim of this study was to detect the histopathology of postmastectomy seromas and the related changes in tumor necrosis factor-α (TNF-α) serum levels. Unilateral mastectomies were performed on 45 female albino rabbits. On day 7, the area of mastectomy was palpated for the presence of swelling and any fluid was aspirated. A biochemical assay of TNF-α serum from all animals (with and without seroma) and that found in the aspirated fluid was performed. Skin flaps and underlying tissues of the mastectomy region were dissected, fixed in 10% formalin, processed and stained for histopathological examination. Seroma developed in 46.6% of the rabbits. The mean volume of seroma fluids was 3.03±2.21 mL. The level of TNF-α in the serum of rabbits that developed seroma was significantly higher than in those that did not. The tissue surrounding the seromas showed persistent granulation tissue containing fibroblasts, inflammatory cells and a large number of newly formed blood vessels surrounded by extravasated blood. This could be attributed to the increased TNF-α serum level, as discovered by the biochemical study. The inflammatory cell infiltrates mainly consisted of eosinophils as well as lymphocytes, macrophages and plasma cells. The postmastectomy seromas showed altered and delayed wound healing. TNF-α levels were elevated in both the seroma fluid and the serum of animals that developed seroma, possibly indicating its role in seroma development.

Abstract: This is in response to the MSM theme monograph Academia-Industry Symposium 2007: Medical Practice and the Pharmaceutical Industry: And Ever the Duo shall Meet.I recall that it was just five years ago when you first wrote to me, informing me about the start of Mens Sana Monographs . I was excited because it was something new, something different that was happening in the field of mental health and philosophy in India.You have come a long way since then. In fact, it is amazing how rapidly MSM has progressed, as testified to by the present theme monograph. Your readers and contributors are no longer confined to India; you are now international in reach and outlook. Please allow me to wholeheartedly congratulate you. It is a remarkable achievement by any standard.The present volume is excellent in its design and contents. The two editorials by Jerome Kassirer and Joel Lexchin are outstanding and deeply thought provoking. The article by Martin Van Der Weyden is equally rewarding and has very useful information. The main monograph has been superbly, very competently, and comprehensively written by both of you.In the series "What Medicine Means To Me," I especially liked the piece by Helen Herrman. Her message of public health psychiatry is particularly relevant for developing countries.The book review of David Healy's book by Leemon McHenry is very refreshing and challenging. I congratulate you on your decision to publish it when other journals were still hesitating.And lastly, the obituary reference to my dear friend Dr. Ravi Kapur by Ajit Bhide and you were so touching; I cried all over again.So keep up your good work, dear friends. May God bless you and may you both achieve many more successes in your careers.

Heart geometry in rats under diabetes mellitus – the role of individual reactivity factors
Kanana N.N.
Морфолог?я , 2009,
Abstract: In 76 rats with alloxan diabetes the relation between heart remodeling and sensitivity to angiotensin II was established. After 14 days, 1, 2 and 3 months the sensitivity of Angiotensin1 receptors was estimated by in vitro test with induced aggregation of platelets. The body and heart mass, volume and thickness of heart ventriculi were measured. The individual peculiarities of Angiotensin1 receptors expression and their role in determination of heart state during diabetes were shown. The hypersensitivity of Angiotensin1 receptors was associated with early myocardial hypertrophy with next dilatation of ventriculi with decrease of their wall thickness.
Cardiovascular mortality: quality diagnostics analysis and causal statistics of lethal outcomes

Abstract: The high cardiovascular mortality (CVM) proves the necessity of verification analysis of cardiovascular death causes. The research goal is to determine the quality, facilities and peculiarities of cardiovascular diseases (CVD) of postmortem diagnostics and statistical recording as a cause of death. 1972 successive cases of CVM in Voronezh, Ryazan and Khanty-Mansiysk have been analyzed. The majority of deaths caused by CVD were classified as fatalities occurring outside hospital and in the absence of medical care (88.0%). Incidence of cardiovascular deaths was confirmed by autopsy in 28.3% cases. With increasing age, the incidence of detecting CVD as a cause of death increased, while the frequency of referral to autopsy consistently decreased. Chronic Ischemic Heart Disease (IHD) forms comprising 48.3% of all CVM were confirmed by autopsy results only in 29.5% of cases. Acute IHD forms (including myocardial infarction) accounted for only 11.6% of CVM; however this diagnosis was based on autopsy results in 72.4% of cases. The high death rate outside hospital and in the absence of medical care with the rare referral to autopsy, especially for elderly having chronic CVD, does not provide reliable statistical information on CVM
