in this study, the genetic diversity of 25 iranian saffron genotypes from three species (crocus speciosus, crocus cancellatus and crocus sativus) has been evaluated using 16 morphological traits and rapd marker. c. sativus was different with speciosus in the leaf number per plant, tepal length, flower weight, inflorescence stem height and the stigma length, but had no significant difference wit...

background: allergy to saffron (crocus sativus) pollen has been described in people involved in processing of saffron flower stamens. profilins have been identified as a pan-allergen in different plant pollens and foods. this molecule is an actin-binding pro-tein with a molecular weight of 12-16 kda found in eukaryotic species. objective: the aim of this study was to generate monoclonal antibod...

PURPOSE To identify the genes and noncoding RNAs (ncRNAs) involved in the neuroprotective actions of a dietary antioxidant (saffron) and of photobiomodulation (PBM). METHODS We used a previously published assay of photoreceptor damage, in which albino Sprague Dawley rats raised in dim cyclic illumination (12 h 5 lux, 12 h darkness) were challenged by 24 h exposure to bright (1,000 lux) light....

This study was designed to investigate the therapeutic effects of saffron (Crocus sativus L.) and its main constituent crocin on neuropathic pain behavioral responses induced by chronic constriction injury (CCI) in rats. Adult male Wistar rats (200 to 250 g) were randomly assigned into 5 groups: Sham + saline, CCI + saline, CCI+ saffron (30 mg/kg), CCI + crocin (15 mg/kg) and CCI + crocin (30 m...

Introduction: Postpartum depression is a common mental health problem that is associated with maternal suffering. The aim of this double-blind clinical trial was to compare safety and efficacy of saffron and fluoxetine in treatment of mild to moderate postpartum depression. Methods: This was a 6-week, double-blind, randomized clinical trial. Subjects were women aged 18-45 years with mild to mod...

In the online false discovery rate (FDR) problem, one observes a possibly infinite sequence of p-values P1, P2, . . . , each testing a different null hypothesis, and an algorithm must pick a sequence of rejection thresholds α1, α2, . . . in an online fashion, effectively rejecting the k-th null hypothesis whenever Pk ≤ αk. Importantly, αk must be a function of the past, and cannot depend on Pk ...

in this paper the separation of saffron stigma from stamen and petal in a vertical wind tunnel has been evaluated. a wind tunnel with adjustable speed of 0.1 m s-1 intervals has been developed and used for the experiments. floating velocities of flower components (petal, stigma and stamen) were measured at one, eight, 38 and 60 hours after harvesting. subsequently, the separation was tested by ...

In the present study, the effect of aqueous extracts of saffron on morphine-induced memory impairment was investigated. On the training trial, the mice received an electric shock when the animals were entered into the dark compartment. Twenty-four and forty-eight hours later, the time latency for entering the dark compartment was recorded and defined as the retention trial. The mice were divide...
