The incidence of pre-lingual hearing loss (HL) is about 1 in 1000 neonates. More than 60% of cases are inherited. Non-syndromic HL (NSHL) is extremely heterogeneous: more than 130 loci have been identified so far. The most common form of NSHL is the autosomal recessive form (ARNSHL). In this study, a cohort of 36 big ARNSHL pedigrees with 4 or more patients from 7 provinces of Iran was investig...

Many Lamiaceae species are consumed in the Lebanese cuisine as food or condiment and are largely used in the traditional medicine of Lebanon to treat various diseases, including microbial infections. In this article we report the traditional medicinal uses of eleven Lamiaceae species: Coridothymus capitatus L., Lavandula stoechas L., Lavandula angustifolia Mill., Mentha spicata L. subsp. conden...

Essential oils distilled from members of the genus Lavandula have been used both cosmetically and therapeutically for centuries with the most commonly used species being L. angustifolia, L. latifolia, L. stoechas and L. x intermedia. Although there is considerable anecdotal information about the biological activity of these oils much of this has not been substantiated by scientific or clinical ...

Considering the ever-increasing state of pollution in different aspects of the environment, ornamental plants and herbs such as Lavandula have become the center of attention mostly due to their availability and use in urban green spaces. Phytoremediation is a modern and economical method which can be applied to metropolises for decreasing metal contaminations in soil, water, and atmosphere. Thi...

Prickly pear fruits constituted valuable foodstuff for humans and animals in arid and semi-arid regions. Two species of prickly pear from Tunisia, Opuntia ficus indica and Opuntia stricta, were investigated for fatty acid composition and physicochemical parameters of the seed oil. No significant difference in either physical or chemical parameters was found between the species. The main fatty a...

For 120 specimens and fi gures of Fragilariforma, 10 Legendre coeffi cients were calculated as shape descriptors. For each half valve apically bisected, 50 x,y coordinates were used to calculate Legendre coeffi cients. Principal components analysis (PCA) was used to ordinate the shape descriptors as a total shape gradient of valve forms. The fi rst four principal components explained 90.3 % of ...

the myelodysplastic syndrome (mds) is a highly heterogenous disorder and karyotype analysis is helpful for diagnostic and prognostic estimation. deletion in long arm chromosome 6 (6q del) as a sole abnormality is a rare event in mds. this is the first case report of del (6q) as the only observed diagnostic change in iran. we also reviewed the literature of this cytogenetic lesion.

Warmer and drier climates have shifted phenologies of many species. However, the magnitude and direction of phenological shifts vary widely among taxa, and it is often unclear when shifts are adaptive or how they affect long-term viability. Here, we model evolution of flowering phenology based on our long-term research of two species exhibiting opposite shifts in floral phenology: Lythrum salic...

objective: profound consumption of medicinal plants products worldwide and public misconception of the products safety puts the urgent need forward as to evaluation of their safe and harmful aspects. in the present study the lavandula angustifolia essential oil was studied with a view to the foregoing criteria. materials and methods: the antimicrobial, antioxidative, hematologic and cytotoxic ...

The aims of this study are to determine the chemical composition of Lavandula angustifolia Mill. and Coriandrum sativum L. essential oils, to evaluate their cytotoxic effects in SH-SY5Y human neuroblastoma cells, to investigate whether an alteration of adenylate cyclase 1 (ADCY1) and of extracellular signal-regulated kinase (ERK) expression can take part in the molecular mechanisms of the essen...
