The pot experiments were conducted in the Department of Life Science and Bioinformatics of Assam University, Silchar. The aim of the present study was to investigate the effect of dual inoculation of Arbuscular mycorrhiza (AM) (Glomus fasciculatum) and Rhizobium on the chlorophyll, nitrogen and phosphorus contents of pigeon pea (Cajanus cajan L.). The results revealed an overall increase in chl...

Glomus tumors are relatively uncommon benign neoplasms, most common in the skin and subcutaneous tissue, but can also occur in the viscera, most often in the stomach. Preoperative diagnosis, when the tumor occurs in the stomach, seems difficult but is important, since glomus tumors of the stomach are essentially benign and amenable to conservative excision, contrary to aggressive gastric neopla...

An intranasal glomus tumor and a sinonasal hemangiopericytoma-like tumor are reported. Both patients were elderly women suffering from nasal bleeding, and presented with a polypoid mass arising in the nasal septum. Microscopically, the glomus tumor displayed a proliferation of uniform rounded or cuboidal epithelioid cells arranged in sheets and interrupted by a rich vasculature with a character...

Gastric glomus tumors are rare, mesenchymal neoplasms, generally described as benign and account for nearly 1% of all gastrointestinal soft tissue tumors. The most common gastrointestinal site of involvement is the stomach, particularly the antrum. Gastric glomus tumors are submucosal tumors that lack specific clinical and endoscopic characteristics, and are often mistaken for the more common g...

Acute oxygen (O2) sensing is essential for individuals to survive under hypoxic conditions. The carotid body (CB) is the main peripheral chemoreceptor, which contains excitable and O2-sensitive glomus cells with O2-regulated ion channels. Upon exposure to acute hypoxia, inhibition of K+ channels is the signal that triggers cell depolarization, transmitter release and activation of sensory fiber...

Onychomatricoma and glomus tumor are two rare subungual neoplasms with distinct clinical and histopathological features. We report a case of onychomatricoma associated with a glomus tumor in the subungual region of the same finger in a 45-year-old woman. Histopathological examination revealed characteristic findings of both onychomatricoma and glomus tumor. To the best of our knowledge, these t...

Neural stem cells (NSCs) exist in germinal centers of the adult brain and in the carotid body (CB), an oxygen-sensing organ that grows under chronic hypoxemia. How stem cell lineage differentiation into mature glomus cells is coupled with changes in physiological demand is poorly understood. Here, we show that hypoxia does not affect CB NSC proliferation directly. Rather, mature glomus cells ex...

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 ...

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...
