The carotid body (CB) is a neural crest-derived organ whose function is to elicit hyperventilation in response to hypoxemia. The CB contains clusters of neuron-like glomus cells enveloped by glia-like sustentacular cells. CB responsiveness to acute hypoxia relies on the inhibition of O2-sensitive K+ channels in glomus cells, which leads to depolarization, Ca2+ entry and release of transmitters ...

ISSN 0001-5555 Glomus tumours are distinctive neoplasms composed of cells resembling the modified smooth muscle cells of the normal glomus body (a specialized form of arteriovenous anastomosis involved in thermal and baroregulation) (1, 2). Vascular tumours with glomus cell morphology occur in ...

Gaeumannomyces graminis var. tritici causes take-all disease, the most important root disease of cereal plants. Cereal plants are able to form a symbiotic association with soil-borne arbuscular mycorrhizal fungi which can provide bioprotection against soil-borne fungal pathogens. However, the bioprotective effect of arbuscular mycorrhizal fungi against soil-borne fungal pathogens might vary. In...

Glomus tumor is an uncommon tumor usually presenting in the dermis. Rarely, it occurred in visceral organs including stomach, liver and long. The majority of glomus tumors were benign. Herein, we present a case of glomus tumor located in the left lobe of the lung in a 49 year-old Chinese male. An irregular mass measuring 3 cm was detected by imaging examination because of his suffering from cou...

Glomus tumors are a rare, benign neoplasm and 75% exist in the subungual region. Extradigital glomus tumors are much more difficult to diagnose because of their atypical location and symptoms. Furthermore, if their symptoms are similar to neuropathic pain, the patient can suffer from misdirected treatment due to misdiagnosis. It is essential to perform careful evaluation of the lesion itself in...

Intravascular glomus tumor in the forearm is very rare and usually presents with persistent pain and focal tenderness. The diagnosis of this condition can be easily missed or delayed. There is no successful treatment so far other than surgical excision in most of cases. We presented a 45-year-old female presented with intravascular glomus tumor in her left forearm. The swelling was excised and ...
