Large-conductance KCa (BK) and other voltage-dependent K(+) channels (Kv) are highly expressed in carotid body (CB) glomus cells, but their role in hypoxia-induced excitation is still not well defined and remains controversial. We addressed this issue by studying the effects of inhibitors of BK (IBTX) and BK/Kv (TEA/4-AP) on [Ca(2+) ]i responses to a wide range of hypoxia at different levels of resting cell Em. IBTX and TEA/4-AP did not affect the basal [Ca(2+) ]i in isolated glomus cells bathed in 5 mm KClo , but elicited transient increases in [Ca(2+) ]i in cells that were moderately depolarized (11-20 mV) by elevation of [KCl]o (12-20 mm)...

Objective: To investigate the clincopathologic and immunohistochemical features of gastric glomus tumors and their differences from gastric neuroendocrine neoplasms. Methods: Six cases of gastric glomus tumors, 8 cases of glomus tumors in other sites and 7 cases of gastric neuroendocrine neoplasms were collected from the Department of Pathology, Taizhou Hospital. The clinicopathological and immunohistochemical characteristics of these tumors were analyzed retrospectively. Results: The gastric glomus tumors were located in the muscularis propria of the antrum and most cases strongly expressed synaptophysin (5/6)...

Background: Glomangiomyoma is a rare histological variant of glomus tumour. Clinically, it mimicks as a haemangioma and is challenging to diagnose. Its occurrence in the neck of a child has not been previously described. Case presentation: A 3 year old girl presented with the complaints of painless progressive neck swelling in the right side for one and half year. Sonography, computed tomography (CT), magnetic resonance imaging (MRI), CT neck angiography and fine needle aspiration cytology (FNAC) were suggestive of vacular malformation i...

INTRODUCTION: Extracutaneous glomus tumors occurring in the bronchus is very rare. Complete resection is basic procedure for treatment of glomus tumor. We present a glomus tumor of the left main bronchus that was successfully treated with rigid bronchoscopy followed by sleeve resection of the left main bronchus. PRESENTATION OF CASE: A 56-year-old man underwent two term resections to glomus tumor that originated from the left main bronchus. Firstly, we performed palliative resection with rigid bronchoscopy to make the correct diagnosis and evaluate the extent of the tumor...

OBJECTIVE Endoscopic third ventriculostomy with choroid plexus cauterization for the treatment of neonatal and infant hydrocephalus has gained popularity in the past decade. Identifying treatment failure is critically important. Results of a pilot study of 2 novel imaging markers seen on fast-sequence T2-weighted axial MRI showed potential clinical utility. However, the reliability of multiple raters detecting these markers must be established before a multicenter validation study can be performed. METHODS Two sets of de-identified single-shot T2-weighted turbo spin-echo axial images were prepared from scans of patients before and after they underwent endoscopic third ventriculostomy with choroid plexus cauterization between March 2013 and January 2016...

This article presents a 48-year-old male patient who presented with pain in the left forearm and weakness and clumsiness in the left hand of 6 months' duration. Flexor motor strength loss of the thumb and the index finger was present and neurophysiologic tests showed findings compatible with axonal injury in the anterior interosseous nerve (AIN) innervated muscles. Magnetic resonance imaging revealed a space-occupying lesion in the proximal forearm resembling a glomus tumor. Excision of the mass and release of the AIN were performed...

Glomus tumours are rare dermal tumours, which very seldom can be seen viscerally. The majority is benign small tumours of the skin. Malignancy has been reported in very few cases worldwide. The diagnosis is made clinically supported by MRI-scans and biopsy of the lesion. We present a case story of a 14-year-old boy, who had an infiltrative glomus tumour of the foot. The tumour met the criteria for malignancy and was operated radically by amputation of the forefoot. The post-operative period was uncomplicated and no metastases were observed neither clinically nor by PET-CT scans...

Glomus tumours are lesions of the glomus body. A solitary glomus tumour is a more common, characteristically painful lesion, frequently located under the nail, whereas multiple glomus tumours are a rare clinical and genetic entity. Multiple glomus tumours are rarely subungual and do not show preference for any particular region of the body. We report a rare case of painful multidigit subungual glomus tumours in both hands.A 34-year-old male patient complained of painful fingertips (right: thumb, index finger, long finger, and ring finger; left: thumb, long finger, ring finger, small finger) on both hands for more than 5 years...

Gastric glomus tumors are extremely rare, constituting approximately 1% of gastric mesenchymal tumors. We report the case of a 45-year-old female patient in whom upper gastrointestinal endoscopy revealed a 3-cm submucosal tumor with a bridging fold in the posterior wall of the antrum of the stomach. Contrast-enhanced computed tomography revealed the tumor to be hypervascular in the arterial phase and exhibit continuous enhancement in the post-venous phase. Dynamic contrast-enhanced magnetic resonance imaging showed that the tumor was hypervascular in the early phase and persistently enhanced in the late phase...

Glomus tumours are benign soft tissue neoplasms. In this paper, we present a case with subungual glomus tumour. Transungual resection was performed to remove tumour. The patient was doing well 6 months after the surgery with no sign of recurrence or nail deformity.

The study is aimed to estimate the diversity of arbuscular mycorrhizal fungi (AMF) in the main producing areas of Salvia miltiorrhiza.Diversity of AMF was surveyed directly on spores isolated from the field soil, collected from 20 sites of 8 provinces. Identification of the AMF was made by observation of spore morphology. At least 27 recognized AMF species were identified in samples from field soil, belonging to seven genera of AMF-Acaulospora, Glomus, Funneliformis, Ambispora, Rhizophagus, Pacispora, and Claroideoglomus...

The chemoreceptors involved in oxygen sensing in teleost fish are neuroepithelial cells (NECs) in the gills, and are analogous to glomus cells in the mammalian carotid body. Purinergic signalling mechanisms involving the neurotransmitters, ATP and adenosine, have been identified in mediating hypoxic signalling in the carotid body, but these pathways are not well understood in the fish gill. The present study used a behavioural assay to screen for the effects of drugs, that target purinergic and adenosine receptors, on the hyperventilatory response to hypoxia in larval zebrafish (Danio rerio) in order to determine if the receptors on which these drugs act may be involved in hypoxic signalling...

Glomus tumors are small, benign tumors that arise from glomus bodies, structures found normally within the dermis that assist in temperature regulation via their vasoconstrictive response to sympathetic stimuli. Glomus tumors are found typically in the hand and are classically a cause of focal pain and temperature sensitivity. They often present as a small blue lesion seen under the nail bed of a finger or a toe and cause point tenderness. Glomus tumors of peripheral nerves are exceedingly rare and can lead to disability akin to compressive neuropathy when present...

To investigate the dynamic changes of endogenous hormones contents in Salvia miltiorrhiza after the inoculation of Glomus versiforme(GV).The contents of endogenous hormones of ABA, ZR, GA, IAA and MeJA by ELISA were measured. Infection rata of GV reached plateau of 90% at the 90th d of inoculation; fresh weight of overground part and leaf number were significantly higher in GV group, with 2.7 and 1.96 fold than that of control; contents of all endogenous hormones apart from ABA in over- and under-ground part were markedly lower (P<0...

We report the clinical case of a 72-year-old man followed for 10years by a specialized pain center, for neuropathic pain poorly systematized, triggered by the contact of the anteromedial face of the right forearm. After surgical excision, histological analysis indicated a well-circumscribed nodule in the subcutaneous region, confirming that the mass was a glomus tumor. In this clinical case, surgical excision allowed an immediate disappearance of the pains without recurrence to this day.
