Background & Aims: Nowadays, there are some undesirable side effects of synthetic drugs, the use of herbal medicines have been widely used as a treatment. New skin extract and pistachio on the above mentioned bacterial infection is more local. The aim of study was to evaluate the effects of antibacterial extract (methanol) prepared from fresh skin pistachios on Gram-positive bacteria (...
In an identity-based proxy re-encryption scheme, a semi-trusted proxy can convert a ciphertext under Alice’s public identity into a ciphertext for Bob. The proxy does not know the secret key of Alice or Bob, and also does not know the plaintext during the conversion. In identity-based proxy re-encryption, the collusion of the proxy and a delegatee may result in the decryption of ciphertext for ...
Purification of nucleic acids is an essential procedure for most experiments in molecular biology. In this paper, the freeze-squeeze method with some modifications is proposed as an alternative methodology for the purification, concentration and recovery of small DNA fragments from agarose gels. The advantage of this alternative methodology is that it enables the recovery of fragments that are ...
Astaxanthin from Haematococcus pluvialis is commercially produced in a two-stage process, involving green vegetative (macrozooid) and red aplanospore stages. This approach has been scaled up to an industrial process but constraints limit its commercial success and profitability, including: contamination issues, high pigment extraction costs, requirements for high light levels and photo-bleachin...
Total suspended particulate matter (TSM) in estuarine and coastal regions usually exhibits significant natural variations. The understanding of such variations is of great significance in coastal waters. The aim of this study is to investigate and assess the diurnal and seasonal variations of surface TSM distribution and its mechanisms in coastal waters based on Geostationary Ocean Color Imager...
Particles size distribution of aerosols and associated metals, and source estimation in Delhi, India
INTRODUCTION Human exposure to particulate matter (PM) was determined in Urban Environment of Delhi, India. Samples were collected using eight stages impactor (Marple Cascade Impactor) at five sites during August to October 2011. Three samples were collected from each site; samples were analyzed -3 in eight size ranges gravimetrically and chemically (for metals). Maximum (985 μg m ) exposure to...
The exact mechanisms by which cell-penetrating peptides such as oligo-arginines and penetratin cross biological membranes has yet to be elucidated, but this is required if they are to reach their full potential as cellular delivery vectors. In the present study, qualitative and quantitative analysis of the influence of temperature, peptide concentration and plasma membrane cholesterol on the up...
To evaluate the physical and chemical stability of a suspension of mycophenolate mofetil (MMF) prepared in the hospital from commercially available MMF capsules and tablets. Extemporaneous pharmacy was used as a feasible method in this experimental study to prepare suspension form of MMF. Suspension formulations were prepared from both tablets and capsules forms of MMF. Thereafter the stability...

Introduction: peganum harmala L. (Zygophyllaceae) and varthemia persica DC (Compositeae) were used for co-culture studies. P.harmala was found to be one of the richest natural sources of β-carboline alkaloids. β-carboline alkaloids posses different neuropharmacologic activities including BDZ antagonism, MAOinhibitor and aminoreuptake inhibitor. The production of β-carboline alkaloids in cell ...
