Sandalwood essential oil (SEO) is extracted from Santalum trees. Although α-santalol, a main constituent of SEO, has been studied as a chemopreventive agent, the genotoxic activity of the whole oil in human breast cell lines is still unknown. The main objective of this study was to assess the cytotoxic and genotoxic effects of SEO in breast adenocarcinoma (MCF-7) and nontumorigenic breast epith...

A microspectrophotometric survey conducted on the retinal photoreceptors of the domestic turkey (Meleagris gallopavo) revealed the presence of five different types of vitamin A1-based visual pigment (rhodopsin) in seven different types of photoreceptor. A single class of rod contained a medium wavelength-sensitive visual pigment (wavelength of maximum absorbance, lambda max, 504 nm). Four diffe...

  Background:Confirmation of olive oil authenticity and particularly virgin olive oil has a great importance. Several advanced chemical and genetic analyses have been used to monitor especial components; however each has its limitations especially when detecting hazelnut-adulterated olive oil. Objectives:The objective of this research is to assess the presence of trace amoun...

The proportion of starch, protein and oil in legume seeds is species dependent. The model legume, Medicago truncatula, has predominantly oil and protein stores. To investigate the regulation of seed oil production we compared M. truncatula with M. orbicularis, which has less oil and protein. The types of protein and fatty acids are similar between the two species. Electron microscopy indicated ...

The present work aims at reducing the friction of rubber soles sliding on ceramic floorings. Fitting bored cylindrical protrusions with different diameters on rubber soles was proposed. Experiments were carried out to evaluate the performance of the proposed protrusions in increasing friction coefficient at dry and contaminated floorings. It was found that, at dry sliding, friction coefficient ...

Background: Crude oil is a very toxic chemical. Recently, the search for protective substances is attracting attention. This study aimed to investigate the hematoprotective potentials of oil palm leaves against the toxicity induced by crude oil. Methods: Male Wistar albino rats (n=36) were divided into six groups of rats (n=6). Group 1 (controls) were fed with normal rat food.  Groups 2 and ...

aim: in this study, the effect of the essential oil of rosa damascena on human colon cancer cell line (sw742) and human fibroblast cells has been reported. background : colon cancer is the second lethal disease after lung cancer. owing to the existence of many side effects and problems related to common treatments such as surgery, chemotherapy and radiotherapy, better substitution is highly nee...

Microfluidic water-in-oil droplets that serve as separate, chemically isolated compartments can be applied for single-cell analysis; however, to investigate encapsulated cells effectively over prolonged time periods, an array of droplets must remain stationary on a versatile substrate for optimal cell compatibility. We present here a platform of unique geometry and substrate versatility that ge...

conclusions according to the results of the present study, it can be concluded that adipose derived mscs can be cultured in serum-free media with no change in their differentiating capacity. this finding gives us a hope for future cell therapy studies and trials with little concern about zoonotic infections or immunological reaction. results the isolated cells showed adherent spindle shaped mor...

The encapsulation of cells together with micro-objects in monodispersed water-in-oil microdroplets offers a powerful means to perform quantitative biological studies within large cell populations. In such applications, accurate object detection is crucial ensure control over the content for every compartment. particular, ability rapidly count and localize objects key future applications single-...
