A Review on Enhancing Organization Security using Attribute-Based Encryption for Data Sharing

With the recent growth of networking, peoples can share their data with others through online, by using social networks or cloud computing but at the same time there has been increasing demand for data security. People would like to make their private data only accessible to the authorized people. In data sharing systems, access policies and the support of policies updates are most challenging issues. Attribute-based encryption (ABE) and Cipher text policy attribute based encryption (CP-ABE) are becoming promising cryptographic solutions to this issue and achives a fine-grained data access control. It enables data owners to define their own access policies over user attributes and enforce the policies on the data to be distributed. The major drawback of these systems is the key escrow problem. The proposed scheme solves the key escrow problem which depends on attribute based encryption technique for the shared data. Paillier Cryptosystem is utilized for encryption of keys for assignment and revocation process while Twofish algorithm is used to encrypt and decrypt stored data of users. Whenever data owner upload personal documents on cloud server, first the keywords will get fetched from the documents and index will be created. Lucene indexing algorithm is used for indexing of keywords. A Blind Storage scheme allows a client to store a set of files on a remote server

Music Therapy and Its Role in Pain Control

Music has occupied our day-to-day life; as it is readily available, accessible and further technological advancement has made access to music a common norm. Music has been present since the very early part of human evolution and has helped in forming society and civilizations. It has served various purposes like social cohesion, emotional expressions, interpersonal communication as well as recreation. Due to its great bonding power; it is important in terms of social dynamics. Music therapy is convenient, inexpensive and user-controlled and seems to be influencing the physiological system positively if rightly used. Vast research is going on to find the right music that could be having a beneficial therapeutic effect. Music seems to affect the pain perception, modulation and also has the affective component to help positively in controlling the pain. This chapter is an attempt to evaluate the various pain modulating effects of music through a systematic music therapy intervention using the vast research work done in this field. This review is consistent to integrate the best scientific evidence for pain relief into practice, education, and research. Music being a non-pharmacologic, nontoxic intervention and is free from adverse effects and also is an inexpensive, low cost modality

Title of the article: Effect of formalin on pulmonary function : a nine months longitudinal study

ABSTRACT Formalin is used in gross anatomy laboratories as a preservative of biological specimen as well as cadavers. Medical students specially 1 st year are exposed to vapours emitted during dissection.To study the long term effect of formalin exposure(during dissection practical) on pulmonary function of 1 st year MBBS students.This is a longitudinal study which comprises of nine months duration.Ninety six medical students [Mean (SD) age of 20.45(1.68)years] were assessed using MIR Spirolab for PFTs within 7 days of admission to their college and reexamined at the interval of three, six and nine months. Analysis was done by one way Anova test.Significant effect was seen in Forced Vital Capacity (FVC), FEV1, PEFR and FEF 25-75% at the end of nine months,however no significant change was seen over the duration of three and six month.Formalin is having adverse effects on the respiratory system over a period of nine months and we recommend a need of precautionary measures to be taken so as to decrease the exposure and also a need for multiple longitudinal studies to be done

Normative data of Ankle brachial pressure Index and Toe brachial index in normal healthy male adult using fully automated vascular Doppler

Context: Peripheral vascular disease affects some 12%–14% of the general population, and the majority of people with the disease are asymptomatic. Risk factors for it are smoking, diabetes mellitus, hyperlipidemia, hypertension, obesity, and syndrome X. The Ankle Brachial Pressure Index (ABPI) is one of the screening noninvasive methods for the diagnosis of peripheral vascular disease. Assessment is performed by fully automated vascular Doppler, which is considered to be accurate; however, normative data are limited. Aims: To measure the normative data of ABPI and Toe brachial index (TBI) in a healthy adult. Settings and Design: A cross-sectional study done in male (n = 59) volunteers in the age group of 18 to 50 years of age group. Methods and Material: Smartdop XT fully automatic Doppler-14 ports (Hadeco, Japan) was used to measure ABPI and Toe brachial index (TBI). Statistical analysis used: Normative value (Mean, SD, Range) was calculated using Systac 13 software. Results: Right-side Ankle Brachial Pressure Index (ABPI) and left-side ABPI at the posterior tibial artery (PT) were 1.061 ± 0.098, and 1.105 ± 0.139, respectively. Right-side ABPI and left-side ABPI at the dorsal pedis artery were 0.86 ± 0.129 and 0.86 ± 0.115. Right-side toe Brachial Pressure Index (TBPI) and left-side ABPI was 0.85 ± 0.185 and 0.822 ± 0.2, respectively. Conclusions: ABPI index of more than 0.9 may be considered normal in the male population in Bhopal; however, we recommend further Multicentric trials across the Indian population

Stem bark extraction of <i style="">Ficus bengalensis</i> Linn for anti-inflammatory and analgesic activity in animal models

39-45In the present study, anti-inflammatory and analgesic effect of aqueous extract of Ficus bengalensis (AEFB) and methanolic extract of F. bengalensis (MEFB) was evaluated in animal models. Preliminary results indicated that MEFB treatment possesses significant anti-inflammatory potential as compared to AEFB. The anti-inflammatory activity of MEFB exhibited in both acute (carrageenan induced hind paw edema and acetic acid induced vascular permeability) and sub-chronic (cotton pellet-induced granuloma) models of inflammation was found to be significant. In addition, the extract also showed significant analgesic activity in acetic acid induced writhing. Pretreatment with MEFB during inflammatory condition (both acute and sub-chronic) prevented increase in malondialdehyde (MDA) formation and myeloperoxidase activity in edematous as well as granulomatous tissue. Further, serum marker enzymes (AST, ALT and ALP) increased in inflammatory conditions were also inhibited with MEFB treatment. Hence, the anti-inflammatory activity observed in the present study with MEFB could be attributed largely to its antioxidant and lysosomal membrane stabilizing effects

Pulmonary functions in air conditioner users

Context: In the modern lifestyle, use of air conditioner (AC) has become very common. Aims: The present study was planned to assess the effect of ACs on pulmonary functions in young healthy non-smoker adults. Settings and Design: This study was a cross-sectional observational study. Sixty-six young adults (40 males and 26 females) using ACs were compared with 70 non-AC users (young adults, 40 males and 30 females). Materials and Methods: Pulmonary function test was done using medical international research (MIR) Spirolab II during home visits. Statistical Analysis Used: GraphPad Prism 5 software was used for analysis. Unpaired t test was used for lung function parameter. Chi- square test was used for the comparison of respiratory symptoms. Results: The results showed significant decrease in forced vital capacity (FVC) (P < 0.05), forced expiratory volume in 1 s (FEV1) (P < 0.05), FEV1 as percentage of FVC in % [FEV1 (%)] (P < 0.05), peak expiratory flow rate in L/s (PEFR) (P < 0.05), forced expiratory flow rate in L/s in 25% of FVC (FEF25%) (P < 0.05), and maximum voluntary ventilation (MVV) (P < 0.01). Frequency of respiratory symptoms was higher in AC users. Conclusions: The results are suggestive of predisposition of AC users toward respiratory disorders in the form of mild airflow obstruction

Hepatoprotective activity of <i style="">Luffa acutangula</i> against CCl₄and rifampicin induced liver toxicity in rats: A biochemical and histopathological evaluation

822-829Hepatoprotective activity of hydroalcoholic extract of Luffa acutangula (HAELA) against carbon tetrachloride (CCl4) and rifampicin-induced hepatotoxicity in rats was evaluated and probable mechanism(s) of action has been suggested. Administration of standard drug- silymarin and HAELA showed significant hepatoprotection against CCl4 and rifampicin induced hepatotoxicity in rats. Hepatoprotective activity of HAELA was due to the decreased levels of serum marker enzymes viz., (AST, ALT, ALP and LDH) and increased total protein including the improvement in histoarchitecture of liver cells of the treated groups as compared to the control group. HAELA also showed significant decrease in malondialdehyde (MDA) formation, increased activity of non-enzymatic intracellular antioxidant, glutathione and enzymatic antioxidants, catalase and superoxide dismutase. Results of this study demonstrated that endogenous antioxidants and inhibition of lipid peroxidation of membrane contribute to hepatoprotective activity of HAELA

Comparative Analysis of Heart Rate Variability Parameters between Surya Namaskar and Stationary Bike Exercise Groups

Background: Yoga practice has multiple health benefits. Surya Namaskar (SN) also known as sun salutation presents mental and physical health benefits equivalent to physical exercise. It consists of a sequence of 12 Hatha yoga postures with coordinated breathing. Aims: This study evaluated the effect of SN against mild intensity stationary cycling exercise (SCE) on parameters of heart rate variability (HRV). Methodology: This study was conducted in the department of physiology of a nationally important institute after obtaining ethics approval. A total of 40 healthy participants (males aged 46 ± 2.3 years) were enrolled in the study and divided into two groups, namely SN group and exercise group (SG and EG). The allocation on the group was based on subjects’ choice and interest in performing SN or SCE. Baseline HRV, anthropometric measurement, and blood pressure were assessed. SG was subjected to 14 rounds of SN in about 20 min and EG to a 20-min mild-intensity stationary cycling session (30%–50% maximal heart rate). Assessments were conducted preexercise and postexercise recovery. HRV was assessed with the NeuralChek device. Results: SN led to increased SDNN, pNN50, RMSSD, and total power, indicating improved autonomic balance, cardiovascular health, and parasympathetic dominance. Conversely, SCE decreased SDNN, pNN50, and RMSSD, suggesting immediate postexercise sympathetic dominance. Spectral analysis of HRV highlighted autonomic balance differences, with SN increasing low frequency (LF%) reflecting both sympathetic and parasympathetic dominance, whereas exercise reduced LF% due to sympathetic activation. Minimal changes were observed in high-frequency percentage. SN combines flexibility, strength, and balance, providing a balanced physical activity. This balance results in a mixed autonomic response, with sympathetic activity for the physical effort and parasympathetic activity for the relaxation components. Conclusions: SN positively impacted HRV, promoting parasympathetic dominance and cardiovascular health, whereas exercise induced sympathetic activation with potential recovery benefits. Monitoring HRV offers insights into cardiovascular fitness and well-being. The study underscores the merits of incorporating yoga such as SN into daily activity routines
