Natural asbestiform fibers are defined 'naturally occurring asbestos' (NOA) and refer to the mineral as a natural component of soils or rocks. The release of NOA fibers into the air from rocks or soils by routine human activities or natural weathering processes represents a risk for human beings. Fluoro-edenite (FE) is a NOA fiber detected in the benmoreitic lava in the area of Biancavilla, South-west slope of Mt. Etna. The aim of the present study was to investigate FE immunotoxicity pathways in a group of 38 occupationally exposed construction workers, in order to find any biological markers of its effect...

Proper organization of microtubule (MT) arrays is essential for numerous cellular functions, including intracellular transport and cell migration. Although the centrosome generally serves as the primary MT organizing center in proliferating animal cells, MTs are also organized at the Golgi apparatus in a wide range of cell types to regulate Golgi ribbon formation that is required for polarized cell migration. Furthermore, differentiated epithelial cells and neurons possess organized non-centrosomal MTs predominantly at the apical cortical regions and the axonal and dendritic neurites, respectively, to establish and maintain their highly polarized morphology...

Histone H2B monoubiquitination (H2Bub1) is recognized as a regulatory mechanism that controls a range of cellular processes. We previously showed that H2Bub1 was involved in responses to biotic stress in Arabidopsis. However, the molecular regulatory mechanisms of H2Bub1 in controlling responses to abiotic stress remain limited. Here, we report that HISTONE MONOUBIQUITINATION1 (HUB1) and HUB2 played important regulatory roles in response to salt stress. Phenotypic analysis revealed that H2Bub1 mutants confer decreased tolerance to salt stress...

Pseudoachondroplasia (PSACH), a severe short-limbed dwarfing condition, is associated with life-long joint pain and early onset osteoarthritis. PSACH is caused by mutations in cartilage oligomeric matrix protein (COMP), a pentameric matricellular protein expressed primarily in cartilage and other musculoskeletal tissues. Mutations in COMP diminish calcium binding and as a result perturb protein folding and export to the extracellular matrix. Mutant COMP is retained in the endoplasmic reticulum (ER) of growth plate chondrocytes resulting in massive intracellular COMP retention...

Some melatonin functions in mammals are exerted through MT₁ and MT₂ receptors. However, there are no reports of their presence in the reproductive tract of the ram, a seasonal species. Thus, we have investigated their existence in the ram testis, epididymis, accessory glands and ductus deferens. Real-time polymerase chain reaction (qPCR) revealed higher levels of m-RNA for both receptors in the testis, ampulla, seminal vesicles, and vas deferens, than in the other organs of the reproductive tract (p < 0...

Metallothioneins (MTs) are a family of cysteine-rich proteins whose biological roles include the regulation of essential metal ions and protection against the harmful effects of toxic metals. Due to its high affinity for many toxic, soft metals, recombinant human MT isoform 1a was incorporated into an electrochemical-based biosensor for the detection of As(3+) and Hg(2+). A simple design was chosen to maximize its potential in environmental monitoring and MT was physically adsorbed onto paper discs placed on screen-printed carbon electrodes (SPCEs)...

Given the global biodiversity crisis, it is crucial to identify methods best suited for conducting inventories. We evaluated the relative merits of Malaise traps (MT) and ground-level yellow pan traps (YPT) to sample male velvet ants (Hymenoptera: Mutillidae) in a Neotropical savanna biodiversity hotspot. We compared richness, number of captures, evenness, composition, and body size of male velvet ants (Hymenoptera: Mutillidae) sampled with both methods in four sites at Parque Nacional da Chapada dos Veadeiros, central Brazil, during 19 d...

Myxozoans are a large group of poorly characterized cnidarian parasites. To gain further insight into their evolution, we sequenced the mitochondrial (mt) genome of Enteromyxum leei and reevaluate the mt genome structure of Kudoa iwatai. While the typical animal mt genome is a compact, 13-25 kb, circular chromosome, the mt genome of E. leei was found to be fragmented into eight circular chromosomes of ∼23 kb, making it the largest described animal mt genome. Each chromosome was found to harbor a large non-coding region (∼15 kb), nearly identical between chromosomes...

BACKGROUND: The dose and aerodynamic particle size distribution (APSD) of drug aerosols' exiting models of the mouth and throat (MT) during a realistic inhalation profile (IP) may be estimated in vitro and designated Total Lung Dose, TLDin vitro, and APSDTLDin vitro, respectively. These aerosol characteristics likely define the drug's regional distribution in the lung. METHODS: A general method was evaluated to enable the simultaneous determination of TLDin vitro and APSDTLDin vitro for budesonide aerosols' exiting small, medium and large VCU-MT models...

In this study, we present an NMR structure of the metallothionein (MT) from the snail Littorina littorea (LlMT) in complex with Cd(2+) . LlMT is capable of binding 9 Zn(2+) or 9 Cd(2+) ions. Sequence alignments with other snail MTs revealed that the protein is likely composed of three domains. The study revealed that the protein is divided into three individual domains, each of which folds into a single well-defined three-metal cluster. The central α2 and C-terminal β domains are positioned with a unique relative orientation...

In this study, the complete mitochondrial (mt) genome sequence of the South China deep-sea giant isopod Bathynomus sp. was determined, and this study is the first to explore in detail the mt genome of a deep-sea member of the order Isopoda. This species belongs to the genus Bathynomus, the members of which are saprophagous residents of the deep-sea benthic environment; based on their large size, Bathynomus is included in the "supergiant group" of isopods. The mt genome of Bathynomus sp. is 14,965 bp in length and consists of 13 protein-coding genes, two ribosomal RNA genes, only 18 transfer RNA genes, and a noncoding control region 362 bp in length, which is the smallest control region discovered in Isopoda to date...

RATIONALE: Mechanical thrombectomy (MT) with a stent retriever (SR), in association with intravenous (IV) rtPA, is now the standard of care in anterior circulation ischemic stroke caused by large vessel occlusion (LVO). Favorable outcome is strongly associated with the successful reperfusion status. New techniques for MT such as contact aspiration (CA) seem promising to increase reperfusion status and clinical outcome in retrospective studies. We aim at ascertaining whether CA is more efficient than stent retriever as a front-line endovascular procedure...
