We describe a gall midge Parampelomyia yukawai Elsayed and Tokuda gen. nov. sp. belonging to the subtribe Schizomyiina (Diptera: Cecidomyiidae: Asphondyliini) based on an integrative taxonomic study. This species forms barely-swollen flower bud galls porcelain berry Ampelopsis brevipedunculata var. heterophylla (Vitaceae) in Japan. The new genus is distinguishable from all known schizomyiine ge...

the asiatic hybrid lily, a bulbous ornamental plant, has a special position in the horticulture as cut flower. to overcome some problems in nutrition of bulb flowers, the use of hydroponic system and nutrient solution is important in the cultivation of these flowers. the asiatic hybrid lilium bulbs “tresor” cultivar, used for the current research were planted under 3 different calcium levels in...

the genus ixiolirion, belonging to the amaryllidaceae family, contains about 3 species distributed in center and southwest of asia and northeast of africa. the iranian flora consists of only one bulbous flowering species; ixiolirion tataricum (pall.) herb., with the persian name of “khiarak”. in the present work, i. tataricum was collected, during the flowering stage, from the sarduiyeh area in...

Potyviruses (genus Potyvirus, family Potyviridae) are transmitted by aphids in a non-persistent manner and cause significant losses in many crops including bulbous ornamentals. Host range, symptoms, physical and biochemical properties of many potyviruses in bulbous ornamentals are reported, but, especially for viruses infecting ornamentals of minor economical importance, sequence data are still...

A variety of mammalian species have been used in studies of epididymal function. The knowledge gained from these laboratory and domestic species has been applied to the human as well, but the anatomy and biology of the human epididymis is not commonly investigated directly. Nonpathological specimens from men within their reproductive years are understandably difficult to obtain, and even when s...

PURPOSE Our objective was to identify histologically and intraoperatively verified focal nerve thickening of the distal intrameatal segment on three-dimensional fast spin-echo (FSE) T2-weighted MR images as a new diagnostic criterion in patients with inflammatory peripheral facial nerve palsy. METHODS Twenty-two patients with clinically diagnosed unilateral (n = 20) or bilateral (n = 2) infla...

Trophic polymorphisms are a prominent form of phenotypic diversification in many animal taxa. Northern temperate lakes have become model systems for the investigation of sympatric speciation due to trophic polymorphisms. Many examples of niche-based phenotypic variation occur in temperate lakes, whereas northern rivers offer few such examples. To further investigate the conditions under which t...

Antibodies to galactocerebroside (GalC) cause major changes in the organization of the membrane sheets elaborated by murine oligodendroglia in culture. Exposure of oligodendroglia to rabbit anti-GalC IgG for 15 min followed by fluoresceinated second antibodies results in patches of surface GalC staining; when second antibodies are applied after 2 hr of anti-GalC, the pattern of staining on memb...
