The correlation between stellar metallicity and the presence of giant planets is well established. It has been tentatively explained by the possible increase of planet formation probability in stellar disks with enhanced amount of metals. However, there are two caveats to this explanation. First, giant stars with planets do not show a metallicity distribution skewed towards metal-rich objects, ...

Giant viruses contain large genomes, encode many proteins atypical for viruses, replicate in large viral factories, and tend to infect protists. The giant virus replication factories can in turn be infected by so called virophages, which are smaller viruses that negatively impact giant virus replication. An example is Mimiviruses that infect the protist Acanthamoeba and that are themselves infe...

In the oxygenated excised squid (Loligo pealii) stellate ganglion preparation one can produce excitation of the stellar giant axons by stimulating the second largest (accessory fiber, Young, 1939) or other smaller preganglionic giant axons. Impulse transmission is believed to occur at the proximal synapses of the stellar giant axons rather than the distal (giant) synapses which are excited by t...

Electron microscopic examinations were made in 20 cases of benign tumor lesions developing in the human lip, buccal mucosa, palate, dorsal area of the tongue and gum. The following findings were obtained. 1) The lumens were observed in pleomorphic adenoma. Microvilli of the tumor cells occurred on the inner side of the luminal wall and the cell organelles were well-developed. 2) The luminal wal...

The Giant Sequoia played several crucial roles in the founding of the modern science of tree -ring dating. These included at least two central theoretical constructs and at least two minor ones; however, historical studies of dendrochronology are actively continuing and this list is expected to expand. Second only to the importance of the ponderosa pine (Pinus ponderosa) in the earliest days of...

Central giant cell granuloma (CGCG) is a relatively uncommon benign bony lesion of a variably aggressive nature. Thought to represent a reparative response to intrabony haemorrhage and inflammation, CGCG was once regarded as a reactive lesion. It is actually an asymptomatic lesion which becomes evident during routine radiographic examination or as a result of painless but visible expansion of t...

We describe the case of a 35 years old man with a nonspecific complaint of a slow growing solid mass in the frontal region. Radiological exams evidenced two more lesions : in the superior and lateral walls of the orbit. Treated with total excision of the lesions and a cranioplastic procedure at the same act, with favorable outcome. Microscopic findings suggested giant cell tumor in the three le...

BACKGROUND Malignant transformation of giant cell tumors of bones, that is, secondary malignant giant cell tumor of bone, is rare. The most common symptoms are local pain and swelling. There are no prior reports of giant cell tumor of bone with fever of unknown origin at the onset. Here we present a case of a secondary malignant giant cell tumor of bone due to malignant transformation 40 years ...

Understanding the impacts of meteorological factors on giant pandas is necessary for future conservation measures in response to global climate change. We integrated temperature data with three main habitat parameters (elevation, vegetation type, and bamboo species) to evaluate the influence of climate change on giant panda habitat in the northern Minshan Mountains using a habitat assessment mo...
