Antioxidant and Free Radical Scavenging Activity in Roots of Hygrophila schulli (Buch.-Ham.) M.R.Almeida & S.M. Almeida

Nowadays herbal medicines form an important part of health care system, due to lots of side effects and complications in the modern medicine. The novel compounds synthesized in plants as secondary metabolites are the potential source of therapeutical uses. Plants produced significant amount of novel compounds to prevent the oxidative stress related diseases and can be used as antioxidant. One such attempt had been made in the present study in investigating the roots of Hygrophila schulli member of acanthaceae family for an antioxidant activity. The roots of H.schulli were extracted using petroleum ether as a solvent. Various assays such as DPPH (1,1-diphenyl 2-picryihydrazyl) free radical, ABTS radical cation, Phosphomolybdeunm reduction assay and ferric reducing power activity were checked for the antioxidant ability and free radical scavenging activity. In all these assays the root extract of H.schulli showed maximum reducing activity of free radical scavenging activity. The IC 50 value of the root extract in each assay was compared with the standard value of ascorbic acid and found Hygrophila schulli has a strong antioxidant and free Radical Scavenging Activity. &nbsp

ROLE OF CLINICAL PHARMACIST IN ASSESSMENT OF DRUG RELATED PROBLEMS OF CARDIOVASCULAR AGENTS IN DEPARTMENT OF CARDIOLOGY IN A TERTIARY CARE HOSPITAL – A PROSPECTIVE OBSERVATIONAL STUDY

In total of 173 prescriptions of the patient, the total number of 329 drug interactions (DIs) was found, in which the 240 interactions were found in male and 89 in the female bearing 72.90% and 27.10%, respectively. Patient was of various age groups, in which the maximum frequency was seen in the age group of 61–70 years having 105 interactions bearing the percentage of 31.9%. According to the participation of different age group of the male and female with their corresponding age. The participation of male is high having frequency of 240 (72.9%) than female participation of frequency 89 (27.1%). The participation of male in the age group of 61–70 years is 83 and the female is 40 in the age group of 51–60 years. Potential DIs (PDIs) were categorized based on the gender. In that compared to 13 (40.6) females, males 19 (59.4%) were found to have more PDIs. Our study is more PDIs in adult patients. Because in adults lacking of nutrition’s and in elderly patients multiple prescribers, multiple drugs and multiple diseases. The number of potential drug-DI (PDDI) increased with an increase in the number of drugs prescribed. The numbers of drug prescribed increase with age. This DI has a potential to increase or decrease the therapeutic effect or to increase the risk of adverse drug reaction. An increased awareness of PDDIs, rational coprescription of drugs, and a close monitoring of patients in whom these drugs are prescribed are recommended. The recommendation is based on the special monitoring and the perspiration of the clinical pharmacist. The DI observed in the geriatric patient is more severe and common in compared to the other groups of study. The geriatric patient is physiological disability in correspond with the first-pass metabolism and the presence of the other diseases which also enables the multiple prescriptions causing polypharmacy. The gender specification also the cause of the interaction, the female is more prone to the DI due to the hormonal distribution in the body and inability of the physiological function to absorb and the distribution. The special training should be provided to the pharmacist for looking forward of the geriatric patient and female patient. The training regarding the prescription their adherence, use, toxicity, and dosage regimen is being properly enabled in the training for the practical application. This study helps to know the different interaction related to the cardiovascular agent with own class of the drug and the other class of drugs used therapeutically to care the disease

Probing Colored Particles with Photons, Leptons, and Jets

If pairs of new colored particles are produced at the Large Hadron Collider, determining their quantum numbers, and even discovering them, can be non-trivial. We suggest that valuable information can be obtained by measuring the resonant signals of their near-threshold QCD bound states. If the particles are charged, the resulting signatures include photons and leptons and are sufficiently rich for unambiguously determining their various quantum numbers, including the charge, color representation and spin, and obtaining a precise mass measurement. These signals provide well-motivated benchmark models for resonance searches in the dijet, photon+jet, diphoton and dilepton channels. While these measurements require that the lifetime of the new particles be not too short, the resulting limits, unlike those from direct searches for pair production above threshold, do not depend on the particles' decay modes. These limits may be competitive with more direct searches if the particles decay in an obscure way.Comment: 39 pages, 9 figures; v2: more recent searches include

Visual ecology of aphids – a critical review on the role of colours in host finding

We review the rich literature on behavioural responses of aphids (Hemiptera: Aphididae) to stimuli of different colours. Only in one species there are adequate physiological data on spectral sensitivity to explain behaviour crisply in mechanistic terms. Because of the great interest in aphid responses to coloured targets from an evolutionary, ecological and applied perspective, there is a substantial need to expand these studies to more species of aphids, and to quantify spectral properties of stimuli rigorously. We show that aphid responses to colours, at least for some species, are likely based on a specific colour opponency mechanism, with positive input from the green domain of the spectrum and negative input from the blue and/or UV region. We further demonstrate that the usual yellow preference of aphids encountered in field experiments is not a true colour preference but involves additional brightness effects. We discuss the implications for agriculture and sensory ecology, with special respect to the recent debate on autumn leaf colouration. We illustrate that recent evolutionary theories concerning aphid–tree interactions imply far-reaching assumptions on aphid responses to colours that are not likely to hold. Finally we also discuss the implications for developing and optimising strategies of aphid control and monitoring

ACUTE TOXICITY STUDIES OF AQUEOUS SEED EXTRACT OF VIGNA UNGUICULATA IN ALBINO RATS

Objective: Increased usage of traditional folklore medicines by the public has led to scientific evaluation of safety of the herbs thereby providing the physicians the data required to employ them in the management of ailments. Seeds of Vigna unguiculata are commonly consumed as vegetables and as a culinary dish in most parts of Asian sub-continent. The present study was carried out to screen phytochemical constituents, evaluate acute toxic effects and determine LD50 of aqueous seed extract of Vigna unguiculata.Methods: Phytochemical screening was carried out as described by Kokate. Acute oral toxicity study was carried out based on OECD guideline 423 and a limit test at a dose of 2000 mg/kg body weight was carried out in female wistar rats. The extract was orally administered in animals at a single dose of 2000mg/kg body weight. Signs of toxicity and mortality were noted after 1, 4 and 24h of administration of the extract for 14 days.Results: Phytochemical screening of the extract revealed the presence of flavonoids, alkaloids and proteins. No mortality and no significant changes were observed in physical observations, behavioral observations, autonomic effects, sensory responses, reflexes, respiratory effects and somatomotor activity in animals which reveal the safety of the extract at dose of 2000 mg/kg body weight.Conclusion: Conclusively, the results suggest that the aqueous extract is not acutely toxic to the rats and LD50 was found to be higher than 2000 mg/kg

Budding yeast ATM/ATR control meiotic double-strand break (DSB) levels by down-regulating Rec114, an essential component of the DSB-machinery

An essential feature of meiosis is Spo11 catalysis of programmed DNA double strand breaks (DSBs). Evidence suggests that the number of DSBs generated per meiosis is genetically determined and that this ability to maintain a pre-determined DSB level, or "DSB homeostasis", might be a property of the meiotic program. Here, we present direct evidence that Rec114, an evolutionarily conserved essential component of the meiotic DSB-machinery, interacts with DSB hotspot DNA, and that Tel1 and Mec1, the budding yeast ATM and ATR, respectively, down-regulate Rec114 upon meiotic DSB formation through phosphorylation. Mimicking constitutive phosphorylation reduces the interaction between Rec114 and DSB hotspot DNA, resulting in a reduction and/or delay in DSB formation. Conversely, a non-phosphorylatable rec114 allele confers a genome-wide increase in both DSB levels and in the interaction between Rec114 and the DSB hotspot DNA. These observations strongly suggest that Tel1 and/or Mec1 phosphorylation of Rec114 following Spo11 catalysis down-regulates DSB formation by limiting the interaction between Rec114 and DSB hotspots. We also present evidence that Ndt80, a meiosis specific transcription factor, contributes to Rec114 degradation, consistent with its requirement for complete cessation of DSB formation. Loss of Rec114 foci from chromatin is associated with homolog synapsis but independent of Ndt80 or Tel1/Mec1 phosphorylation. Taken together, we present evidence for three independent ways of regulating Rec114 activity, which likely contribute to meiotic DSBs-homeostasis in maintaining genetically determined levels of breaks
