Arbuscular mycorrhiza (AM) can help plants to tolerate arsenic (As) toxicity. However, plant responses are found to vary with the host plant and the AM fungal species. The present study compares the efficacy of two AM fungi Rhizoglomus intraradices (M1) and Glomus etunicatum (M2) in amelioration of As stress in wheat (Triticum aestivum L. var. HD-2967). Mycorrhizal (M) and non-mycorrhizal (NM) wheat plants were subjected to four levels of As (0, 25, 50, and 100 mg As kg(-1) soil). Although As additions had variable effects on the percentage of root colonized by the two fungal inoculants, each mycobiont conferred benefits to the host plant...

The poor quality and low productivity of cultivated liquorice (Glycyrrhiza uralensis) continues to put pressure on wild plant populations. As arbuscular mycorrhizal fungi are known to support plant growth and in some cases even to enhance the accumulation of valuable molecules in the plant, the effect of Glomus mosseae on the growth and active ingredient contents was evaluated in liquorice plants grown under nutrient deficiency. We created a nutrient-deficient environment by mixing paddy soil, washed river sand, and pumice at a ratio of 1:5:1...

Glomus tumors are painful benign neoplasms. They commonly present in the hand and are mostly solitary lesions. We report a rare case of multiple glomus tumors in the lower leg. Moreover, 1 of the tumors was in the tarsal tunnel. Resection of the tumors resulted in the early diagnosis of glomus tumors and complete symptom relief. Because of its rarity, diagnosing an extradigital glomus tumor is difficult. Recognition of glomus tumors allows for an early diagnosis and resection, and preoperative magnetic resonance imaging helps in the detection of multiple lesions...

Glomus tumors (GTs) are rare, perivascular soft tissue tumors. Although GTs are usually found in the subcutaneous tissue, they may be detected in extracutaneous sites and mucosal areas. Transducing-like enhancer of split 1 (TLE1) is a highly useful immunohistochemical marker, which basically helps in differential diagnosis of synovial sarcoma. Based on a coincidental detection of TLE1 in one GT case, we studied 26 additional GT cases to establish the importance and distribution of TLE1 in GTs. Of 24 subcutaneous GTs, 22 (91...

Most fungi are known to synthesize siderophores under iron limitation. However, arbuscular mycorrhizal fungi (AM fungi) have so far not been reported to produce siderophores, although their metabolism is iron-dependent. In an approach to isolate siderophores from AM fungi, we have grown plants of Tagetes patula nana in the presence of spores from AM fungi of the genus Glomus (G. etunicatum, G. mossae & unidentified Glomus sp.) symbiotically under iron limitation and sterile conditions. A siderophore was isolated from infected roots after 2-3 weeks of growth in pots containing low-iron sand with Hoagland solution...

Arbuscular mycorrhizal fungi (AMF) are widespread soil fungi that can form endosymbiotic structures with the root systems of most plants and can improve the tolerance of host plants to heavy metals. In the present study, we investigated the effects of AMF (Glomus coronatum) inoculation on the tolerance of Tagetes patula L. to Cu. Almost all of the non-mycorrhizal plants exposed to 100 μM Cu died after 3 d, whereas phytotoxicity was only observed in mycorrhizal plants that were exposed to Cu concentrations greater than 100 μM...

We report 2 cases of vaginal glomangiomyoma in a 53-year-old who presented with a painful vaginal mass, and a 56-year-old who had postmenopausal bleeding and in whom an incidental vaginal mass was identified and resected at the time of hysterectomy. Histologic examination of the resected masses showed solid, circumscribed, benign, smooth muscle-predominant tumors with interspersed small islands of epithelioid glomus cells. The glomus cells were intimately related to small-caliber blood vessels and showed no cytologic atypia or mitotic activity...

Fine root endophytes (FRE) are arbuscule-forming fungi presently considered as a single species-Glomus tenue in the Glomeromycota (Glomeromycotina)-but probably belong within the Mucoromycotina. Thus, FRE are the only known arbuscule-forming fungi not within the arbuscular mycorrhizal fungi (AMF; Glomeromycotina) as currently understood. Phylogenetic differences between FRE and AMF could reflect ecological differences. To synthesize current ecological knowledge, we reviewed the literature on FRE and identified 108 papers that noted the presence of FRE and, in some, the colonization levels for FRE or AMF (or both)...

Cranial nerve palsy could be one of the presenting features of underlying benign or malignant tumors of the head and neck. The tumor can involve the cranial nerves by local compression, direct infiltration or by paraneoplastic process. Cranial nerve involvement depends on the anatomical course of the cranial nerve and the site of the tumor. Patients may present with single or multiple cranial nerve palsies. Multiple cranial nerve involvement could be sequential or discrete, unilateral or bilateral, painless or painful...

Glomus tumors are rare and benign hamartomas, arising from neuro-myo-arterial proliferation and deriving from mesenchymal origin. As they have a long-term impact on the individual's quality of life, the primary complaint is unbearable pain. The aim of this study was to assess the clinical and functional outcomes of their surgical treatment, and to review their clinical, radiological and therapeutic features. We performed a retrospective study over a 16-year period including 31 patients with an upper limb glomus tumor...

To describe the normal anatomy and histology of the adult coccygeal body (CB) and to discuss about the origin and function. Using immunohistochemistry, we examined 29 CBs found in 32 elderly donated cadavers without macroscopic pathology in the pelvis. The CB was usually located in or near the anococcygeal ligaments. It was almost always composed of multiple masses or nodules of round glomus cells (smooth muscle actin, or SMA++). However, the CB sometimes contained abundant dilated veins with scattered glomus cells...

The differential diagnosis for knee pain is extensive. Glomus tumors comprise approximately 1.6% of soft-tissue tumors in the extremities. Classic subungual tumors occur more frequently in women, whereas ectopic locations are more common in men. Unusual locations include the stomach; lungs; trachea; bones; intestines; fallopian tubes; and intraneural, neuromal, and intravenous locations. We present the case of a 50-year-old man with a 12-year history of enlarging right knee mass found to be a glomangioma. This case report discusses the incidence, presentation, imaging characteristics, histology, and management of glomus tumors of the knee...

To the best of our knowledge, this is the first case report of middle ear extramedullary hematopoiesis (EMH) in a pediatric patient as well as the first bilateral presentation reported in both children and adults. We report a 13-year-old African-American female with sickle cell disease who developed bilateral hearing loss, with magnetic resonance imaging findings consistent with bilateral glomus tympanicum (GT). Upon excisional biopsy, however, EMH was diagnosed histologically. Besides its novelty, this case highlights the importance of considering EMH in the differential diagnosis of GT including cases with bilateral presentation that may be otherwise highly suggestive of the familial form of GT...

REVIEW

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 fibers that stimulate the brainstem respiratory center to produce hyperventilation. The molecular mechanisms underlying O2 sensing by glomus cells have, however, remained elusive...
