Water recycling and the production of drinking water have recently become a very actual topic. Pressure membrane processes make it possible to produce with quality higher than or comparable product conventionally used such as sand filtration flotation. The operation technologies requires specialist knowledge. By correctly analysing input parameters controlling operating process, technology is c...
Calcium channels are cell membrane proteins that play an important role in control the Ca ion flux through the membrane. In this study, the effect of external constant electric field on the dynamics of calcium ions in a L-type channel, located within a stochastically fluctuating medium, is modeled via the application of the molecular dynamics (MD) simulation method. The obtained results show th...
Cell membrane has a critical and vital role in functioning and existence of nerve cells that form central nervous system (CNS) in mammals. Disruption of nerve membrane that normally occurs following an accident injuring spinal cord is known to be the major cause of paralysis. In most occasions, spinal cord injuries are not leading to complete cut in spinal cord fibers but are known to cause cru...
Background and Objective: It has recently been shown that the application of amniotic membrane conditioned medium is effective in cancer treatment. In this study, the effect of amniotic stem cells conditioned medium on the activity of Hsp90 and Cdk4 expression, were investigated in cancer cells. Materials and Methods: Two cancer cell lines HeLa and MDA-MB-231 were treated with the supernatan...
To study the effect of bacterial siderophore on the second cropping of maize (SC645) under drought stress conditions, a factorial experiment was arranged in a randomized complete block design with three replications. Two irrigation treatments (75 (I1: unstressed control) and 120 mm evaporation from Class-A pan (I2: delayed irrigation)) and two siderophore application treatments (S1: with and S2...
the major limitation in the application of bioactive molecule is their low permeation across plasma membrane. in 1988 it was discovered, that a natural polycationic protein, the trans-acting activator of transcription (tat) of the human immunodeficiency virus (hiv-1), passed very efficiently through cell membrane of cultured mammalian cells. tat became known as the first cell penetrating peptid...
Recovery of sugars from cane molasses (i.e. the by-product of sugar industries) is of great interest to industry and academia. The prerequisite for refning cane molasses is removal of pigments and suspended solids present in the molasses. In this work, the utilization of membrane separation for clarifcation and decoloration of cane molasses has been examined. Three oper...
Background and Objective: Previous studies showed that basement membrane pattern is structuraly different in SCC and BCC tumors. BSCC is an epithelial malignant tumor with two histopathologic pattern similar to SCC and BCC. This study was aimed to compare the basement membrane pattern in SCC , BCC and BSCC tumors . Materials and Methods: In this laboratory study, the medical files of patients...
The technique to fabricate nanofibrous mat by electro-spinning has been known for a long time. But the attempts to use the electospun nanofiber mats, also known as electro-spun nanofiber membranes (ENMs), for filtration purposes began only recently. Among many membrane filtration processes, air cleaning by the removal of dust particles has already been commercialized and the product has been in...
Postharvest improvement of water relations and water uptake of cut flowers and control of microbial contamination of preservative solutions is one of the most important strategies in maintaining postharvest quality and prolonging of cut flowers vase life; especially for leafy flowering stems such as alstroemeria. This experiment was conducted to evaluate the effects of different peppermint’s es...
