In October 2012, in a survey in order to study the flora of paddy fields and aquatic ecosystems of Gilan province (N Iran), we encountered an unknown species in “Aynak lagoon” in southeast of Rasht, covered surface of about 12 ha pond densely. Comparing the flora of pond with previous years or adjacent ponds showed that, the new weed was dominant in interference with natural flora of aquatic ec...

Gladiolus (Gladiolus grandiflorus L.), a popular bulbous cut flower, has high demand in both domestic (Pakistani) as well as international markets. Five potential, exotic cultivars of gladiolus, ‘Cantate’, ‘Corveira’, ‘Eminence’, ‘Essential’ and ‘Fado’ were evaluated to determine the cultivar effects on yield and quality, to compare their relative performance and recommend their suitability for...

The epithelial tissue forming the posterior aspect of the apical foramen in the upper incisor of the rat was reconstructed from 1 μm thick serial cross sections. Like the lower incisor, this portion of the odontogenic organ in the upper incisor was composed of a bulbous and a "U"-shaped part. However, the bulbous part was considerably blunter and the "U"-shaped part much larger in circumference...

Garlic is an herbaceous annual bulbous plant in the family Amaryllidaceae grown for its pungent and edible bulb. Among various biotic factors hindering production productivity, purple blotch plays a predominant role changing crops morpho-physiological characters, thus deteriorating metabolic activity turn affecting yield considerably. Fungicides have been recommended control of disease, however...

Abstract This paper considers the issue of preserving biological diversity Iridaceae family representatives in FRC SSC RAS. The research was carried out humid subtropical climate on Black Sea coast Krasnodar Territory. objects were following representatives: Iris L., Crocus Gladiolus Freesia Eckl. ex Klatt, including cultivar samples from Russian and foreign breeding, as well species natural fl...

The case of a 3 11/12-year-old Chinese boy with the dental abnormalities of "otodental" dysplasia is reported. Hearing was normal. Dental anomalies consisted of delayed eruption of globe-shaped molars, bulbous deciduous canines, and double pulp chambers in the molars. Radiographs taken 4 years later showed taurodontic molars, supernumerary microdontic teeth, retarded formation of premolars, and...

What are they? Dendritic spines are small protrusions that emerge from the dendrites of neurons (Figure 1). Most excitatory synapses in the brain are found on spine heads. Typically, a spine consists of a bulbous head, volume 0.001–1 μm3, at the end of a thin spine neck, diameter around 0.1 μm. A 100 μm length dendrite can contain several hundred spines. The human cerebral cortex is thought to ...
