Critical review on specific symptomology of Vataj and Vatkaphaj Gridhrasi (Sciatica) and its Pathyapathya

The diseases affecting the locomotor system are increasingly seen in present era. This condition considerably reduces the human activity in terms of social and professional life. As Acharya Charaka says that the person who do not follow code of conducts for healthy life, are more prone to develop disease. Low back pain is a common disorder it affects about 40% of people affected with a set of symptoms including pain caused by irritation or compression of one of the five lumbar spine nerves roots of each of the left or right or both sciatic nerves is termed as Sciatica, sciatic neuralgia. Mild to pricking pain, feeling of pulsation, and stiffness in lumber region radiates to back of thigh and popliteal region, calf muscle till feet are the Cardinal features of disease Gridhrasi. Based on Dosha predominance Gridhrasi is two types Vataja Gridhrasi and Vata-Kaphaja. Acharya Charaka mentioned Ruka (Pain), Toda (Pricking sensation), Stambha (Stiffness), and Muhuspandana (Twitching) in Sphik and radiating towards the Kati, Prushtha, Uru, Janu, Jangha and Pada respectively. These are the cardinal symptoms of Vataja Gridhrasi. In Vata-Kaphaja type of Gridhrasi in addition to the above symptoms, Tandra (Drowsiness), Gaurava (Heaviness) and Aruchi (Anorexia) are also present

SUMO-conjugating enzyme (Sce) and FK506-binding protein (FKBP) encoding rice ( Oryza sativa L.) genes: genome-wide analysis, expression studies and evidence for their involvement in abiotic stress response

We report an in-depth characterization of two major stress proteins namely SUMO-conjugating enzyme (Sce) and peptidyl prolyl cis-trans isomerase (PPIase) in rice (Oryza sativa L.). Sce mediates addition of SUMO group to various cell proteins, through process referred to as SUMOylation. Rice nuclear genome has two putative genes encoding the Sce protein (OsSce1 and OsSce2). PCR-amplified full-length OsSce1 cDNA functionally complemented the growth defect in yeast cells lacking the equivalent Ubc9 protein (ScΔubc9). RT-PCR analysis showed that transcript levels of OsSce1 and OsSce2 in rice seedlings were regulated by temperature stress. OsSce1 protein was localized to the nucleus in onion epidermal cells as evidenced by the transient GFP expression analysis following micro-projectile gun-based shooting of an OsSce1-GFP fusion construct. PPIase proteins assist molecular chaperones in reactions associated with protein folding and protein transport across membrane. There are 23 putative genes encoding for FK506-binding proteins (FKBPs; specific class of PPIase) in rice genome. OsFKBP20 cDNA was isolated as a stress-inducible EST clone. Largest ORF of 561 bases in OsFKBP20 showed characteristic FK506-binding domain at N-terminus and a coiled-coil motif at C-terminus. RNA expression analysis indicated that OsFKBP20 transcript is heat-inducible. OsFKBP20 over-expression in yeast endowed capacity of high temperature tolerance to yeast cells. Yeast two-hybrid analysis showed that OsSce1 protein physically interacts with the OsFKBP20 protein. It is thus proposed that OsSce1 and OsFKBP20 proteins in concert mediate the stress response of rice plants

An Early Diagnosis of Thalassemia: A Boon to a Healthy Society

The β-thalassemia is a hereditary blood disorders, characterized by reduced or absent synthesis of the hemoglobin beta chain that cause microcytic hypochromic anemia. An early diagnosis, economical test, awareness programs and prenatal screening will be a milestone for the eradication of this genetic disorder and to reduce burden of the health sector of a country subsequently the economics. Initially, the diagnosis of β-thalassemia depends on the hematological tests with red cell indices that disclosed the microcytic hypochromic anemia. Hemoglobin analysis shows the abnormal peripheral blood smear with nucleated red blood cells, and reduced amounts of hemoglobin A (HbA). In severe anemia, the hemoglobin analysis by HPLC reveals decreased quantities of HbA and increased the level of hemoglobin F (HbF). The decrease level of MCV and MCH are also associated with β-thalassemia. There are various different molecular techniques such as ARMS PCR, allele-specific PCR, Gap PCR, denaturing gradient gel electrophoresis, reverse dot blotting, DGGE, SSCP, HRM, MLPA, sequencing technology and microarray available to identify the globin chain gene mutations. These molecular techniques can be clustered for detection by mutation types and alteration in gene sequences

NON-VON's Performance on Certain Database Benchmarks

In a paper by Hawthorn and DeWitt, the projected performance of several proposed database machines was examined for three relational database queries. The present paper investigates the performance of a massively parallel machine called NON-VON for the same queries under comparable assumptions. In the case of simple queries, a NON-VON machine of comparable size to those considered by Hawthorn and DeWitt is found to be somewhat faster than the fastest machines examined in their study; for a more complex database operation, NON-VON is shown to be five to ten times faster than the fastest of these machines

The benefits of physical activity in individuals with cardiovascular risk factors : a longitudinal investigation using fNIRS and dual-task walking

ABSTRACT: Cardiovascular fitness is linked to better executive functions, preserved gait speed, and efficient cortical activity. Older adults with cardiovascular risk factors (CVRFs) typically show poor cognitive performance, low physical fitness, and altered brain functioning compared with healthy individuals. In the current study, the impact of regular physical activity on cognition, locomotion, and brain functions was explored in a cohort of older adults with low or high CVRFs. Cortical activation of the frontal areas was investigated using functional Near-Infrared Spectroscopy (fNIRS) at baseline, at 6 months and at 12 months. Evoked cortical response and behavioral performance were assessed using the dual-task walking paradigm, consisting of three conditions: single cognitive task (2-back task), single walking task (walking), and dual-task (2-back whilst walking). Results show greater task-related cortical response at baseline in individuals with high CVRFs compared to those with low CVRFs. Moreover, participants with high CVRFs benefitted the most from participating in regular physical activity, as their cortical response decreased at the 12-month follow-up and became comparable to that of participants with low CVRFs. These changes were observed in conjunction with improved cognitive performance and stable gait speed throughout the 12-month period in both groups. Our findings provide evidence that participation in regular physical activity may be especially beneficial in individuals with CVRFs by promoting brain and cognitive health, thus potentially contributing to prevention of cognitive decline. Future research may explore whether such effects are maintained in the long-term in order to design ad-hoc interventions in this specific population

Iron and zinc concentrations in peanut (Arachis hypogaea L.) seeds and their relationship with other nutritional and yield parameters

Biofortification (delivery of micronutrients via micronutrient-dense crops) can be achieved through plant breeding and offers a cost-effective and sustainable approach to fighting micronutrient malnutrition. The present study was conducted to facilitate the initiation of a breeding programme to improve the concentration of iron (Fe) and zinc (Zn) in peanut (Arachis hypogaea L.) seeds. The experiment was conducted with 64 diverse peanut genotypes for 2 years in eight different environments at the International Crops Research Institute for the Semi-Arid Tropics, Patancheru, India to assess the genetic variation for Fe and Zn concentrations in peanut seeds and their heritability and correlations with other traits. Significant differences were observed among the genotypes and environments for Fe (33–68 mg/kg), Zn (44–95 mg/kg), protein (150–310 mg/g) and oil (410–610 mg/g) concentration in seeds and their heritability was high, thus indicating the possibility of improving them through breeding. As seen in other plants, a significant positive association between concentrations of Fe and Zn was observed. Trade-offs between pod yield and Fe and Zn concentrations were not observed and the same was also true for oil content. Besides being high yielding, genotypes ICGV 06099 (57 mg/kg Fe and 81 mg/kg Zn) and ICGV 06040 (56 mg/kg Fe and 80 mg/kg Zn) had stable performance for Fe and Zn concentrations across environments. These are the ideal choices for use as parents in a breeding programme and in developing mapping populations

Fish Oil for the Reduction of Atrial Fibrillation Recurrence, Inflammation, and Oxidative Stress

AbstractBackgroundRecent trials of fish oil for the prevention of atrial fibrillation (AF) recurrence have provided mixed results. Notable uncertainties in the existing evidence base include the roles of high-dose fish oil, inflammation, and oxidative stress in patients with paroxysmal or persistent AF not receiving conventional antiarrhythmic (AA) therapy.ObjectivesThe aim of this study was to evaluate the influence of high-dose fish oil on AF recurrence, inflammation, and oxidative stress parameters.MethodsWe performed a double-blind, randomized, placebo-controlled, parallel-arm study in 337 patients with symptomatic paroxysmal or persistent AF within 6 months of enrollment. Patients were randomized to fish oil (4 g/day) or placebo and followed, on average, for 271 ± 129 days.ResultsThe primary endpoint was time to first symptomatic or asymptomatic AF recurrence lasting >30 s. Secondary endpoints were high-sensitivity C-reactive protein (hs-CRP) and myeloperoxidase (MPO). The primary endpoint occurred in 64.1% of patients in the fish oil arm and 63.2% of patients in the placebo arm (hazard ratio: 1.10; 95% confidence interval: 0.84 to 1.45; p = 0.48). hs-CRP and MPO were within normal limits at baseline and decreased to a similar degree at 6 months (Δhs-CRP, 11% vs. −11%; ΔMPO, −5% vs. −9% for fish oil vs. placebo, respectively; p value for interaction = NS).ConclusionsHigh-dose fish oil does not reduce AF recurrence in patients with a history of AF not receiving conventional AA therapy. Furthermore, fish oil does not reduce inflammation or oxidative stress markers in this population, which may explain its lack of efficacy.

Longitudinal Impact of Physical Activity on Brain Pulsatility Index and Cognition in Older Adults with Cardiovascular Risk Factors: A NIRS Study

Recent studies have shown that optical indices of cerebral pulsatility, including cerebral pulse amplitude, are linked to cerebrovascular health. A chronically higher cerebral pulsatility is associated with cognitive decline. Although it is widely known that regular physical activity improves cognitive functions, little is known about the association between physical activity and the optical index of cerebral pulsatility. This study assessed the impact of 12 months of regular physical activity on the changes in the optical index of cerebral pulsatility and explored its association with cognition. A total of 19 older adults (aged 59–79 years) with cardiovascular risk factors (CVRF) completed the study. Low-intensity, short-duration walking as a brief cardiovascular challenge was used to study the impact of regular physical activity on post-walking changes in cerebral pulsatility index. The participants walked on a gym track while a near-infrared spectroscopy (NIRS) device recorded hemodynamics data from the frontal and motor cortex subregions. Our data indicated that 12 months of physical activity was associated with lower global cerebral pulse amplitude, which was associated with higher cognitive scores in executive functions. Further, the global cerebral pulsatility index was reduced after short-duration walking, and this reduction was greater after 12 months of regular physical activity compared with the baseline. This may be an indication of improvement in cerebrovascular response to the cardiovascular challenge after regular physical activity. This study suggests that 12 months of physical activity may support cognitive functions through improving cerebral pulsatility in older adults with CVRF

Association between Statin Use and Balance in Older Adults

ABSTRACT: Background: Several medications have been associated with an increased risk of balance deficits and greater likelihood to sustain a fall, representing a large health and economic issue. Statins are regularly prescribed to prevent strokes and heart attacks, but their impact on balance is unknown. The aim of this paper was to determine whether statin use is associated with poorer balance performances in older adults. Methods: All participants, one group taking statins (n = 34), and the other group not taking statins (n = 31), completed a balance assessment with their eyes closed and their eyes opened on a MatScan Pressure Sensing Mat. Center of Pressure (CoP) velocity, peak-to-peak distance, and standard deviation were collected in both anteroposterior (AP) and mediolateral (ML) directions. Multiple linear regression analyses were performed for each balance outcome, testing the statin use status as a predictor and controlling for appropriate factors including participants characteristics, lipid profile, and cardiovascular disease. Results: After controlling for confounding factors, statin use significantly predicted both CoP ML-Amplitude (beta = 0.638, p = 0.004) and ML-Velocity (beta = 0.653, p = 0.002) in the eyes-opened condition. Conclusions: The present study detected a negative association between statin use and balance control in the ML direction, suggesting that caution should be taken when prescribing statins in older adults, as this could decrease ML stability and ultimately increase fall and fracture risks
