Pollen and Leaf Micromorphological Characteristics of Spiny Almonds (Prunus subgenus Amygdalus) in Iran.

This study investigates the micromorphological characteristics of pollen grains and leaf epidermal cells from 20 accessions across four species of spiny almonds using scanning electron microscopy. Thirteen quantitative traits of pollen grains, including exine sculpturing, were analyzed alongside qualitative features such as shape, exine sculpture type, and aperture type. Additionally, four quantitative and five qualitative features of the leaf epidermis were examined, focusing on cuticular ornamentation patterns, types of epicuticular wax, and stomatal measurements.

Using microscopic techniques for taxonomic implications of seed and fruits of Delphinium L. (sensu lato) (Ranunculaceae).

In present research, micromorphological characters of the genus Delphinium L. (sensu lato) Ranunculaceae seeds and fruits were studied using microscopic techniques. A total of 37 species were studied using light (LM) and scanning electron microscopy (SEM) to evaluate seeds and fruits micromorphological characteristics for the taxonomic identification and species relationship in the genus.

, a Bioactive Essential Oil: Chemical Composition and Biological Activities.

is an aromatic plant traditionally used for treatment of infections and gastrointestinal diseases. In the present study, the volatile oil of the plant was obtained by hydrodistillation and analyzed by GC-MS. In addition, antibacterial and anti- activities of this essential oil were determined using disc diffusion and agar dilution methods, respectively.

Foliar and stem epidermal anatomy of the tribe Cynoglosseae (Boraginaceae) and their taxonomic significance.

Foliar and stem epidermal anatomical features of the tribe Cynoglosseae have been studied in detail for the taxonomic identification using light microscopy (LM) and scanning electron microscopic (SEM) techniques. A comparative study was conducted on different plant parts (leaf and stem epidermal anatomy) of 25 species belonging to eight genera of the tribe Cynoglosseae (Boraginaceae) collected from different phytogeographical regions of Iran for the first time. Different qualitative and quantitative characteristics were observed in detail using LM and SEM.

Chemical composition, antioxidant and antimicrobial activity of essential oil and extracts of Tragopogon graminifolius, a medicinal herb from Iran.

Tragopogon graminifolius DC., family Compositae, is widely consumed as a green vegetable in the west of Iran and for the treatment of gastrointestinal and hepatic ailments. In this study, the chemical composition of the essential oil from T.

Antifungal and antibacterial activities of Pentanema divaricatum and its active constituent.

The antimicrobial activity of ethanol and chloroform extracts of Pentanema divaricatum Cass. was studied using the conventional disk diffusion method. The extracts' highest antimicrobial activity was observed against Aspergillus niger.

Inhibitory effect of aerial parts of Scrophularia striata on matrix metalloproteinases expression.

It has been shown that destruction of the extracellular matrix (ECM) by matrix metalloproteinases (MMPs) leads to tumor invasion, metastasis and angiogenesis. The aim of the present research was to verify the effects of a total extract and sequential extracts of Scrophularia striata Boiss (Scrophulariaceae) on MMPs activity. The fibro sarcoma cell line (wehi-164) was used to assess MMPs inhibitory effect.

Chemopreventive effect of Cousinia shulabadensis Attar & Ghahraman ethanol extract.

Matrix metalloproteinases (MMPs) play an important role in several pathologic processes such as malignancy in which they facilitate invasion and metastasis and can be targets for anticancer therapies. Here, in this study, we investigated the cytotoxicity effect of Cousinia shulabadensis Attar & Ghahraman extract as well as its impact on MMPs activity using a model of cell line (Fibrosarcoma-Wehi164). To assess anti-invasiveness potentials, a modified zymoanalysis method was used to measure MMP-2 and MMP-9 activities in the conditioned-media.
