M. Padma Sundari,B. Dharani Priya
Asian Journal of Medical Sciences , 2013,
Abstract: The object of our study is to observe the epidemiological distribution and association of Tuberculosis (TB) co-infection with HIV among the Visakhapatnam zone of Andhrapradesh. It is mainly due to Tuberculosis and HIV has been closely linked and HIV infection has contributed to a significant increase in the worldwide incidence of tuberculosis. According to WHO, the proportion of TB cases co-infected with HIV was also found rising being 2-10 times greater for 1997 estimates than for 19902. By producing a progressive decline in cell-mediated immunity, HIV alters the pathogenesis of tuberculosis, greatly increasing the risk of developing disease in co-infected individuals and leading to more frequent extra pulmonary involvement and atypical radiographic manifestations. In the present analysis it was found that in new smear pulmonary TB cases; there was an increase trend in number of cases in both male and female. According to smear positive and smear negative TB cases, male are more prone to TB (71.77% smear positive and 63.83% smear negative) than female (28.22% smear positive and 36.16% smear negative). In all the TB cases registered through RNTCP 4186 TB Patients are reported to be tested for HIV before or during the treatment. Out of those 4,186 cases, 558 are HIV positive.

Asian Journal of Medical Sciences , 2014, DOI: 10.3126/ajms.v5i2.8789
Abstract: Background: Adipocytokines, secreted from the adipose tissues have profound effect on complex metabolic and endocrine functions. Among them, leptin and adiponectin are the most recognized molecules which influence body homeostasis and metabolism. Moreover, patients with thyroid disease usually exhibit disturbances of these metabolic activities. Thus adipocytokines and thyroid hormones may influence similar aspects of metabolic functions. Objective: The main objective of current study was to evaluate the association and impact of leptin and adiponectin on thyroid stimulating hormone (TSH) among hypothyroid patients. Materials and Methods: For the present study a total 350 individuals were enlisted, out of which 200 were hypothyroid patients and 150 age and sex matched healthy controls aged ≥ 12 years. The serum TSH, leptin and adiponectin concentration were measured by CLIA method and results were computed by statistical methods such as mean, standard deviation, standard error and correlation using MS-Excel 2007. Result: Our data showed that hypothyroidism was more prevalent in the age group 30-50(62%) and an elevated TSH level was observed with advancing age among the patients as compared to controls. The inverse relation of leptin and adiponectin has been seen among the patients. When patients were compared with controls, they were with normal values which were in the range of standardized lab values leptin (3.7-13ng/dl) and adiponectin (5-10μg/ml). Conclusion: In conclusion, our data interpreted variations in the level of leptin and adiponectin among the hypothyroid individuals with high TSH level. As abnormal levels of these adipocytokines indicates the risk for other metabolic diseases like cardiovascular disease, obesity etc. DOI: http://dx.doi.org/10.3126/ajms.v5i2.8789 Asian Journal of Medical Science, Volume-5(2) 2014: 67-72

Indian Journal of Human Genetics , 2003,
Abstract: Opportunity for natural selection has been studied among the women of Kshatriya caste population from rural and urban areas of north coastal Andhra Pradesh. The urbanrural difference for different demographic characteristics is not significant. The contribution of fertility component for both Crow′s index and Jonston and Kensinger′s index is more. The present study is compared with other Andhra populations. The decreased mortality differentials in Kshatriyas suggest that this component was directly affected by the better socio-economic level and reflects on the population′s transitional phase.
Lifetime Enhancement of Cluster Based Wireless Sensor Network through Energy Efficient MAC Protocol  [PDF]
B. Priya, S. Solai Manohar
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.79200
Abstract: The efficient use of energy is an important performance metric to extend the lifetime of wireless sensor networks. Since major energy consumption of node is due to its transceiver, the design of MAC protocol plays a vital role in sensor network design. In cluster based sensor networks, due to the different functions of member node and cluster head node, the usage of common MAC protocol results increased energy consumption. To overcome this problem, a novel energy efficient hybrid MAC protocol (EEHMAC) for cluster based wireless sensor networks is proposed in this paper. The proposed EEHMAC protocol uses E-TDMA (Energy efficient TDMA) for intra-cluster communication and FDMA (Frequency Division Multiple Access) for inter-cluster communication. IDS (Iterative Deepening Search) based Scheduling algorithm is used for assigning time slot and frequency slot to nodes. Nodes in EEHMAC follow the periodic duty cycle, which reduces the idle listening, and overhearing problems. Simulation results reveal that an average of 18% energy saving is achieved compared to LEACH (Low Energy Adaptive Clustered Hierarchy) protocol and 10% energy is saved in comparison with GH-MAC (Graph theory based Hybrid MAC) protocol. It is evident that delay of EEHMAC is reduced by 17% and throughput is increased by 15% under all traffic conditions. These results demonstrate that EEHMAC performs better than existing MAC protocols in terms of energy efficiency, delay and throughput.
Evaluation of ovarian cysts in adolescents  [PDF]
Jessica R. Zolton, Priya B. Maseelall
Open Journal of Obstetrics and Gynecology (OJOG) , 2013, DOI: 10.4236/ojog.2013.37A1004
Abstract:

The presentation of an adnexal mass in an adolescent is a concerning event for the patient and the family. Patients are most likely to present with abdominal pain or a palpable mass. The diagnostic imaging of choice is pelvic ultrasonography. The majority of these lesions are benign ovarian cysts. These cysts should be followed with ultrasound, as many will spontaneously regress. Further evaluation with laboratory tests may also be warranted, which will aid in diagnosis and treatment. Ovarian cysts that are failed to resolve, severely symptomatic, or concerned with malignancy require surgical intervention. Laparoscopy has shown to be beneficial in the adolescent population and should be the procedure of choice. In addition, ovarian conservation is the ideal treatment in order to continue normal pubertal development and preserve reproductive health.

Alterations in glutathione system in adult and pup rat brains following chronic aluminum exposure
Anand Priya,Nehru B
Indian Journal of Occupational and Environmental Medicine , 2006,
Abstract: Glutathione is a major regulator of the redox equilibrium in cells, so its deficit weakens the tissue resistance to oxidants. Several pathologies that affect the nervous system involve oxidative stress, possibly associated with the decrease of glutathione content. The nervous system is particularly susceptible to oxidative insults and is therefore dependent on its glutathione content, especially during development stage, where brain metabolism and growth are maximal. To study the involvement of glutathione in brain redox homeostasis, we set up an experimental model of aluminum (Al) neurotoxicity (AlCl3+ 100 mg/kg b.wt) for eight weeks to both developed and developing rats. In the developing group exposure of Al for 60 days was done post natally, 21 days to feeding mother (lactation period) and 39 days to pup rats. Similar dose for eight weeks were given to adult rats. The result showed a statistically significant ( P < 0.01) decrease in Total glutathione, reduced glutathione and oxidized glutathione in both cerebrum and cerebellum region of pup brains. A similar decrease was observed in adult group. Also, aluminum exposure resulted in significant decrease in ATPase activity in both the regions of the brain of developing and developed rat brain. Thus the present study indicates that aluminum exposure (100 mg/kg b.wt) to both adult and pup rat results in the decline of glutathione system which alters the redox ratio significantly. Further, aluminum exposure also decreases the ATPase activity which in turn could affect the glutathione synthesis.

Abstract: Sound velocity, density, and viscosity values have been measured at T = 303 K for four binary systems of morpholine + methanol, ethanol, 1-propanol, and 1-butanol. From these data, acoustical parameters, such as adiabatic compressibility, free length, free volume, and internal pressure, have been estimated using the standard relations. The results are interpreted in terms of the molecular interaction between the components of the mixtures. The observed excess values in all the mixtures indicate that the molecular symmetry existing in the system is highly disturbed by the addition of morpholine molecules. The interaction energy terms of the statistical mixing are also verified for these binary systems, and the dipole-dipole interactions are found to be predominant and are greatly affected by the chain length of the primary alkanols.

EE-MAC: Energy Efficient Hybrid MAC for WSN
B. Priya,S. Solai Manohar
International Journal of Distributed Sensor Networks , 2013, DOI: 10.1155/2013/526383
Abstract: A novel low power medium access protocol energy efficient MAC (EE-MAC) for wireless sensor network is proposed in this paper. EE-MAC targets for improving energy efficiency, delay performance and packet delivery ratio by considering various load conditions of the network. This protocol is based on the hybrid of TDMA and FDMA approaches. The novel idea behind EE-MAC is that it uses the priority concept with hybrid MAC scheduling in order to achieve its objectives. The performance of EE-MAC is obtained through simulations for various packet sizes, traffic loads, and different scenarios which show significant improvements in packet delivery ratio, energy efficiency, and delay compared to existing protocols. 1. Introduction Wireless sensor network (WSN) is an application driven design determined by the requirements of network behaviour. Wireless sensor networks have been proposed for emergency applications, such as building fire monitoring and response. The network must be traffic and topology adaptive for this type of application. The algorithm used for communication should be delay tolerant during normal periodic monitoring and energy efficient. Conventional WSN applications like [1–3] have concentrated on inactive low-duty cycle sensing and monitoring, in-network data aggregation, and asynchronous operation designed to extend the lifetime of sensor nodes. Conversely, the applications like real-time streaming for voice and video require comparatively high bandwidth utilization, throughput, and bounded end-to-end delay of few milliseconds. Thus, the design of effective WSN medium access control (MAC) protocols has become a more challenging task and results in a very different design trade-off than other wireless networks. Existing WSN hardware devices such as MICAZ [4], Telos [5], and CMU Firefly [6] play a major role in designing WSN-MAC layer protocol. These hardware devices use CC2420 radio [7] in order to access the multiple channels. Designing MAC protocols for a given limited radio bandwidth (19.2?Kbps in MICA2 and 250?Kbps in MICAZ and Telos) and to increase the network throughput is a crucial task. Almost all of the proposed protocols for WSN MAC layer such as [8–14] use only one single physical frequency. Due to limited bandwidth of the sensor node hardware and the small MAC layer packet size, multifrequency MAC protocols of general wireless networks are not suitable for wireless sensor networks. For the operation of MAC protocol in multiple frequencies, single low-power transceiver of WSN node is not capable due its inability of simultaneous

Abstract: ABSTRACT: Oxygen is an element obligatory for life. Biological combustion produces harmful intermediates called free radicals. Free radicals are continuously produced by the body’s aerobic life and our metabolism. Antioxidants are the substances, which act against oxidative compounds. Under normal conditions the body’s antioxidants convert ROS to prevent the over production of free radicals. Recently, natural foods and food derived antioxidants such as vitamins and phenolic phytochemicals, have received growing attention, because they are known to function as chemo preventive agents against oxidative damage and are considered beneficial for human health. The present study was conducted to compare the antioxidant activity of fresh and dry rhizomes of Curcuma zedoaria. The methanol extract of both the rhizomes showed good radical scavenging activity.
