Abstract: Popa [10] introduced the useful concept of rare continuity. The purpose of this paper is to highlight the notions of rare sets and dense sets in Generalized Topology and minimal structure space. Further, we study their properties using the closure and interior operators. We apply this notion of sets to define a new class of rarely (λX mX )* - continuous functions and investigate their characterizations.
Registration of Brain Images using Fast Walsh Hadamard Transform

Computer Science , 2010, DOI: 10.5120/1745-2053
Abstract: A lot of image registration techniques have been developed with great significance for data analysis in medicine, astrophotography, satellite imaging and few other areas. This work proposes a method for medical image registration using Fast Walsh Hadamard transform. This algorithm registers images of the same or different modalities. Each image bit is lengthened in terms of Fast Walsh Hadamard basis functions. Each basis function is a notion of determining various aspects of local structure, e.g., horizontal edge, corner, etc. These coefficients are normalized and used as numerals in a chosen number system which allows one to form a unique number for each type of local structure. The experimental results show that Fast Walsh Hadamard transform accomplished better results than the conventional Walsh transform in the time domain. Also Fast Walsh Hadamard transform is more reliable in medical image registration consuming less time.

Abstract: Image registration has great significance in medicine, with a lot of techniques anticipated in it. This paper discusses an approach for medical image registration. It registers images of the mono or multi modalities for CT or MRI images using Modified Adaptive Polar Transform. The performance of the Adaptive Polar Transform with theproposed technique is examined. The results prove that the proposed method performs better than Adaptive Polar Transform technique. The proposed method reduces the errors and also the elapsed time for registration. An analysis is presented for the medical image registration of brain images using Adaptive Polar Transform and Modified Adaptive Polar Transform.

Abstract: Background/Aim: Islet regeneration in chronic pancreatitis (CP) is relevant for managing the associated loss of endocrine function. Because ductal epithelial cells were earlier demonstrated to differentiate into pancreatic endocrine mass, we evaluated their proliferation and differentiation in chronic pancreatitis. Methods: Pancreatic ducts were obtained from surgically resected pancreata of 12 patients with chronic pancreatitis and 15 control subjects. CK19 positive ductal cells were evaluated for their proliferating and differentiating abilities upon immunostaining with Ki 67 and hormone positivity for insulin and glucagon, apart from monitoring Pdx 1 expression. Results: In comparison to the controls, a greater number of proliferating pancreatic ductal epithelial cells (PDECs) were observed under conditions of CP. The increase in Pdx1 expressing PDECs (22%) and proliferating Pdx1 expressing PDECs (30%) was significant (P < 0.04). Number of cells expressing insulin/glucagon in the exocrine ducts increased significantly in CP as compared to controls (P < 0.02) andβcell mass adjacent to the ducts increased by 28%.Conclusion: Enhanced capability of PDECs to proliferate and differentiate into endocrine mass suggests that PDECs form a source of progenitors for cell based therapy in chronic pancreatitis.

Abstract: Background and Objective: Islet autotransplantation is performed to preserve endocrine function in patients undergoing pancreatic resections for painful chronic pancreatitis. We characterized islets isolated from chronic pancreatitis patients (CP) of tropical region. Patients and Methods: Pancreatic tissues were obtained from CP patients with and without diabetes undergoing pancreatic resections (n = 35) and brain-dead multi organ donors (n = 6; considered as controls). Islets isolated were assessed for yield, purity, viability and in vitro islet function (Glucose stimulated insulin release, GSIR) as per standard protocols. Results: Islets from CP patients without diabetes were similar to controls in yield (control 4120 - 6100 IE/g, CP 3550 - 5660 IE/g), purity (control 78% ± 12%, CP 70% ± 8.2%) and viability (control 85% ± 8%, CP 81% ± 10%) and islets from CP patients with diabetes showed decreases in yield (3002 - 2300 IE/g), purity (61% ± 16%) and viability (62% ± 21%). Islets measuring 50 - 200 μ were similar in abundance in controls (94.74% ± 3.2%) and CP patients with and without diabetes, 86.31% ± 4.9%, 91.03% ± 3.8%. GSIR of islets from CP patients and controls were similar at 5.5 mM glucose (2.8 - 3.1 μU/ml). However, GSIR at 16.5 mM glucose was decreased in CP patients (control 18.5 ± 0.6, CP without diabetes 11.8 ± 0.3, CP with diabetes 4.3 ± 0.3 μU/ml). Conclusion: Our results demonstrate suitability of islets isolated from CP patients of tropical region for autotransplantation.
Klinefelter Syndrome With Leg Ulcers

Indian Journal of Dermatology , 1999,
Abstract: Leg ulcers are frequently caused by venous insufficiency, arterial insufficiency, neuropathy, or a combination of these factors. Klinefelter syndrome in association with chronic leg ulcers have been reported earlier. We report a case of Klinefelter syndrome with non- healing ulcer. The diagnosis of the Klinefelter syndrome was confirmed by karyotyping.

Abstract: Baramahal was a part of Kongu country. It was located in between two great Military stations of Bangalore and Trichnopoly and was naturally a centre of extensive commerce. Baramahal was the gateway of Mysore and ever dominated to key of the south. The district is situated with many forts had been a battle field in Tamil Nadu, for the trial of strength between Tipu and the Britisher. Hyder Ali came to power with in a short time in this place. Afterwards it fell into the hands of Tipu, he managed to control the territory upto 1792. After the third Mysore war (1790-92) Tipu was forced by the treaty of Srirangapatnam 1792 to cede half his territories to the hands of East India company. These territories included Baramahal and Salem referred in the records as the conquered country in South India.

Genetic variation in nitrogen and phosphorus content in broiler excreta

Abstract: The nutrient content in the soil surrounding the poultry farms has increased as a result of the high content of nitrogen (N) and phosphorus (P) in the poultry excreta. The current study aimed to propose a strategy to reduce the N and P content in the excreta by genetic selection in broilers for efficient nutrient utilization. The traits measured were the percentage of N in the excreta (PNE) and the percentage of P in the excreta (PPE), on a dry matter basis. Individual 24-hr excreta samples were collected from 6 wk old birds. Excreta samples were collected from birds of two distinct genetic lines raised in a commercial breeding farm. Analysis of excreta samples collected during the first period (197 bird samples belonging to 15 sire families) and second period (278 birds belonging to 25 sire families) suggested a heritability of 0.08, 0.16 for PNE and 0, 0.20 for PPE, respectively. Phenotypic and genetic correlations between the measured traits from the two lines were very low; however, phenotypic correlation analysis of PNE and PPE with other traits of commercial interest showed some favorable as well as neutral associations. The results suggest that genetic selection of birds for PNE and PPE could improve the environment and the market value of the birds.
