Owing to rising production and use of engineered nanoparticles (ENPs) in the myriad of consumer applications, ENPs are being released into the environment where their potential fate and effects have remained unclear. With naturally occurring arbuscular mycorrhizal fungus (AMF; Glomus intraradices) in soils, their influence (positive or negative) on ENPs toxicity in plants is not well documented. Herein, we investigated potential influence of AMF on the growth and development in fenugreek (Trigonella foenum-graecum) under varied Zinc oxide nanoparticles (ZnONPs) treatments (0, 125, 250, 375 and 500 μg g(-1))...

Glomus tumors arising in the urinary bladder are extremely rare, and only two cases have been reported in the English Literature. We present a case of a 58-year-old man with an asymptomatic mass of the anterior wall of the bladder that measured 2.5 × 2.5 cm. Endoscopic excision was performed, and the tumor was diagnosed as symplastic glomus tumor. The patient finally underwent robotic-assisted partial cystectomy, and he remains healthy without any recurrence to date.After reviewing this case and previous reports, we analyzed the clinicopathologic features and treatment options for this rare neoplasm...

This study aims to determine the spatiotemporal dynamics of root colonization and spore density of arbuscular mycorrhizal fungi (AMF) in the rhizosphere of olive trees (Olea europaea) with different plantation ages and under different climatic areas in Algeria. Soil and root samples were seasonally collected from three olive plantations of different ages. Other samples were carried out in productive olive orchards cultivated under a climatic gradient (desertic, semi-arid, subhumid, and humid). The olive varieties analysed in this study were Blanquette, Rougette, Chemlel and the wild-olive...

Our aim was to identify pericyte-specific markers for the analysis of formalin-fixed paraffin-embedded (FFPE) human tissue samples, and to characterize perivascular myoid cell neoplasms phenotypically. Previously identified pericyte markers failed to distinguish pericytes from other cellular types, such as vascular smooth muscle cells (vSMCs) and fibroblasts, in immunohistochemical (IHC) analysis. However, we compared gene expression profiles between pericytes, vSMCs, and fibroblasts, and performed human skin vasculature IHC analysis, which led to the identification of myosin 1B (MYO1B) as a novel pericyte marker...

Salinity is one of the serious abiotic stresses adversely affecting the majority of arable lands worldwide, limiting the crop productivity of most of the economically important crops. Sweet basil (Osmium basilicum) plants were grown in a non-saline soil (EC = 0.64 dS m(-1)), in low saline soil (EC = 5 dS m(-1)), and in a high saline soil (EC = 10 dS m(-1)). There were differences between arbuscular mycorrhizal (Glomus deserticola) colonized plants (+AMF) and non-colonized plants (-AMF). Mycorrhiza mitigated the reduction of K, P and Ca uptake due to salinity...

A greenhouse study was conducted to compare the relative efficacy of different approaches to managing Meloidogyne incognita on green bean. These approaches included chemical (fumigant, non-fumigant, seed dressing, and seed dip), biological (the egg-parasitic fungus, Paecilomyces lilacinus and the mycorrhizal fungus Glomus sp.), physical (soil solarization), and cultural (chicken litter and urea) methods. Accordingly, nine different control materials and application methods plus nematode-infected and non-infected controls were compared...

Glomus tumors are uncommon, benign, small neurovascular neoplasms derived from glomus bodies in the reticular dermis. Glomus bodies are found throughout the body to regulate body temperature and skin circulation; however, they are concentrated in the fingers and the sole of the foot. The typical presentation is a solitary nodule in the subungual or periungual area of the distal phalanx. The primary treatment of choice is surgical removal. We investigated expression of vascular endothelial growth factor (VEGF) using immunohistochemistry in glomus tumors of the fingers...

Telocytes are a special type of interstitial cells characterized by distinctive cellular extensions with alternating thin segments (podomers) and dilations (podoms). Telocytes establish contact with various cells and structures, but their role in the regulation of the function of many cell types is still obscure. The aim of the current study was to investigate the morphology, histochemistry, and immunohistochemistry of telocytes, and their distribution, organization, and morphometric measurements in different layers of the adult bovine uterine tube...

A recent study showed that hypoxia activates a Ca(2+)-sensitive, Na(+)-permeable non-selective cation channel (NSC) in carotid body glomus cells. We studied the effects of mitochondrial inhibitors that increase Ca(2+) influx via Ca(2+) channel (Cav), and receptor agonists that release Ca(2+) from endoplasmic reticulum (ER) on NSC. Mitochondrial inhibitors (NaCN, FCCP, H2S, NO) elevated [Ca(2+)]i and activated NSC. Angiotensin II and acetylcholine that elevate [Ca(2+)]i via the Gq-IP3 pathway activated NSC. However, endothelin-1 (Gq) and 5-HT (Gq) showed little or no effect on [Ca(2+)]i and did not activate NSC...

The accumulation, distribution, and speciation of contaminants, such as arsenic, in rice can be affected by soil microorganisms such as arbuscular mycorrhizal fungi (AMF). As a potential measure to control contaminant acquisition in rice, the status and performance of AMF in the field need to be investigated. Root samples of rice plants were collected in seven different cities in Guangdong, Jiangxi, Hubei, and Jiangsu Provinces in China in order to investigate the colonization rate of AMF. The total DNA of the roots was extracted, followed by PCR and sequencing, and further confirmed the existence of AMF...

We report a case of a 76-year-old man that referred to our hospital because of progressive mixed right hearing loss, aural fullness and pulsatile tinnitus synchronized with heart beats. Otoscopic examination revealed a reddish pulsatile mass beyond tympanic membrane. CT and MRI scans showed a class C glomus tumor. Anamnesis and a complete physical examination, with careful differential diagnosis, should be obtained to rule out highly vascularized middle ear lesion before any invasive procedure.

Cholesterol granuloma (CG) is the most common benign lesion of the petrous apex, however, it can grow significantly large and become destructive causing a diagnostic dilemma. This case presents a 25-year-old female with 2-year history of left-sided progressive and profound hearing loss, a transient left-sided facial paralysis and cranial nerve 10 palsy who presented with a blue middle ear mass. Her diagnosis did not become apparent until direct visualization intraoperatively. The objective of this case study is to highlight the destructive capabilities of CG and the importance to keep it in the differential diagnosis of a large, erosive, expansile skull base lesion in order to avoid overly aggressive resection or other unnecessary treatment...

BACKGROUND: Hydrogen sulfide (H2S), a gasotransmitter, is generated from L-cysteine by mainly 3 enzymes, cystathionine-γ-lyase (CSE), cystathionine-β-synthase, and 3-mercaptopyruvate sulfurtransferase in cooperation with cysteine aminotransferase. The H2S-forming enzymes, particularly CSE, are overexpressed under the pathological conditions such as inflammation, neuronal or neuroendocrine differentiation and cancer development. Given that Cav3.2 T-type Ca2+ channels mediate some of the biological activity of H2S, we focus on the role of the H2S/Cav3...

We retrospectively collected cases of surgically proven extradigital glomus tumor (EDGT) and reviewed their demographic, clinical, and sonography features. A total of 18 single, subcutaneous EDGTs were gathered. All but one were located in the extremities. EDGTs typically appear as a small, hypoechoic, homogeneous, or slightly inhomogeneous, well-delimited nodule, disposed horizontally and painful under probe pressure. Intranodular vascularization is always present. Feeding artery and efferent vein are typical but inconstant findings...

Sorghum is an economically important crop, a model system for gene discovery and a biofuel source. Sorghum seedlings were subjected to three microbial treatments, plant growth promoting bacteria (B), arbuscular mycorrhizal (AM) fungi mix with two Glomus species (G. aggregatum and G. etunicatum), Funelliformis mosseae and Rhizophagus irregularis (My), and B and My combined (My+B). Proteomic analysis was conducted followed by integration with metabolite, plant biomass and nutrient data. Out of 366 differentially expressed proteins in sorghum roots, 44 upregulated proteins overlapping among three treatment groups showed positive correlation with sorghum biomass or element uptake or both...

The understanding of the response of arbuscular mycorrhizal fungi (AMF) community composition to fertilization is of great significance in sustainable agriculture. However, how fertilization influences AMF diversity and composition is not well-established yet. A field experiment located in northeast China in typical black soil (Chernozem) was conducted and high-throughput sequencing approach was used to investigate the effects of different fertilizations on the variation of AMF community in the rhizosphere soil of maize crop...

INTRODUCTION: Tumors affecting structures in the vicinity of jugular foramen such as glomus jugulare require microsurgical approach to access this region. These tumors tend to alter the normal architecture of the jugular foramen by invading it. Therefore, it is not feasible to have correct anatomic visualization of the foramen in the presence of such pathologies. Hence, a comprehensive knowledge of the jugular foramen is needed by all the neurosurgeons while doing surgery in this region...

In order to obtain an arbuscular mycorrhizal fungi (AMF) native inoculum from Sierra de Moa and determine the most appropriate conditions for its big scale production, four light and temperature combinations were tested in three plant species (Calophyllum antillanum, Talipariti elatum and Paspalum notatum). Growth and development parameters, as well as the mycorrhizal functioning of the seedlings were evaluated. The natural light treatment under high temperatures (L-H) was the most suitable for the growth and development of the three plant species, showing the highest total biomass values, mainly of root, and a positive root-shoot ratio balance...
