In a garden experiment we investigated the response to continuous removal of either flower buds or rosette buds in three perennial grassland species (Hypochaeris radicata, Succisa pratensis and Centaurea jacea), which differ in longevity and flowering type. We distinguished two possible responses: compensation for lost buds by making more buds of the same type, and switching towards development...

The sensory organs for taste in chickens (Gallus sp.) are taste buds in the oral epithelium of the palate, base of the oral cavity, and posterior tongue. Although there is not a pan-taste cell marker that labels all chicken taste bud cells, α-Gustducin and Vimentin each label a subpopulation of taste bud cells. In the present study, we used both α-Gustducin and Vimentin to further characterize ...

background: alveolar echinococcosis (ae) is a chronic, rare and sometimes lethal parasitic infection in humans, caused by the larval stage of the fox tapeworm echinococcus multilocularis. this study aimed to investigate the clinical aspects and treatment outcomes of patients with alveolar hydatid disease. methods: the medical records of patients with alveolar echinococcosis admitted between 199...

hereby we report a case of well-differentiated intraosseous osteosarcoma in the sacrum. a 32-year-old woman was admitted to our hospital with a low echo-level mass in the pelvis searched by ultrasound in a routine physical examination. radiographically, the mass was misdiagnosed as a benign bony tumor originating from the sacrum. the tumor was completely resected and pathological diagnosis was ...

hydatidsis is a zoonosis transmitted by domestic and wild animals. two distinct clinical presentations are as followes: unilocular of cystic hydatid disease and the more malignant form, called alveolar hydatid disease.this case report presents a patient who complained of chest pain and hemoptysis and his lung ct scan suggested solid tumor. he was found to have alveolar diseae which responded to...

background radiographs play an integral role in the assessment of periodontal disease. in recent years, advent of digital imaging has revolutionized radiology in dentistry. patients and methods in this diagnostic accuracy study, 48 inter proximal surfaces were evaluated in eight patients. these patients had alveolar bone loss in anterior regions because of periodontitis. intraoral (parallel per...

Successive changes in the vascular pattern during the osseous healing of extraction wounds were investigated by studying microvascular casts under a scanning electron microscope. The casts were prepared utilizing the plastic injection method, after the extraction of the upper four incisors of the Japanese monkey (Macaca fuscata). Five days after extraction, vascular buds have sprouted from a pr...

The architecture of spray cut chrysanthemum is crucial for the quality and quantity flower production. However, mechanism underlying plant still needs to be clarified. In this study, we measured nine architecture-related traits 195 varieties during a two-year period. results showed that number upper primary branches, lateral buds branch length widely varied. Additionally, height had significant...

Sonic hedgehog (Shh) signalling by the polarizing region at the posterior margin of the chick wing bud is pivotal in patterning the digits but apart from a few key downstream genes, such as Hoxd13, which is expressed in the posterior region of the wing that gives rise to the digits, the genes that mediate the response to Shh signalling are not known. To find genes that are co-expressed with Hox...

The G-protein subunit alpha-gustducin, which is similar to rod transducin, has been implicated in the transduction of both sweet- and bitter-tasting substances. In rodents, there are differences in sensitivity to sweet and bitter stimuli in different populations of taste buds. Rat fungiform taste buds are more responsive to salts than to sweet stimuli, whereas those on the palate respond predom...
