These findings were further confirmed with an impressive tumor accumulation pattern displayed in a xenograft of human cancer bearing nude mice. On account of their impressive biocompatibility and photophysical features, PSP-Y-AuNCs can exploited for the real-time fluorescence imaging of cancer tissues. Graphical abstract Fluorescent gold nanoclusters (PSP-Y-AuNCs) fabricated using a non-toxic natural polysaccharide (PSP001) demonstrated pH sensitive fluorescence emission pattern. The increased fluorescence readouts at acidic conditions and excellent biocompatibility made the PSP-Y-AuNCs an appealing candidate for in vivo tumor imaging applications.Differentiation of stem cells can be modulated by a combination of internal and external signals, including mechanical cues from the surrounding microenvironment. Although numerous chemical and biological agents have been recognized in regulating stem cells' fate, little is known about their potential to directly sense the mechanical signals to choose differentiation into a specific lineage. The success of any stem cell transplantation effort, however, hinges on thorough understanding of the fate of these cells under different signals, including mechanical cues. Various proteins are involved in the mechanical sensing process. ATN-161 chemical structure Of these, Piezo proteins, as the ion channels activated by membrane tension and mechanical signals, play an important role in translating the information of mechanical forces such as rigidity and topography of the extracellular matrix to the intracellular signaling pathways related to stem cell homing and differentiation. They also play a key role in terms of shear stresses and tensile loads in expansion systems. This review highlights key evidence for the potential of mechanically gated ion channels expressed by human stem cells, and the mechanotransduction and past mechanomemory in the fate of transplanted stem cells. With this knowledge in mind, by controlling the tissue-specific patterns of mechanical forces in the scaffolds, we may further improve the regulation of homing, the differentiation, and the fate of transplanted stem cells.There is considerable interest in understanding how contents within the gut wall (including microbiome) can activate sensory nerve endings in the gut that project to the central nervous system. However, we have only recently begun to understand the location and characteristics of extrinsic spinal afferent nerve endings that innervate the lower gastrointestinal (GI) tract. Our aim is to identify the nerve endings in the mouse distal colon that arise from single spinal afferent neurons. C57BL/6 mice were anaesthetised and single dorsal root ganglia (DRG) between lumbosacral L6-S1 were injected with dextran biotin. Mice recovered for 7 days. Animals were then euthanized and whole colons removed, fixed and stained for calcitonin-gene-related-peptide (CGRP). Single spinal afferent nerve axons were identified entering the distal colon that ramified along many rows of myenteric ganglia, often giving rise to varicose nerve endings. These same axons bifurcated in the circular muscle giving rise to 4-5 groups of branching-type intramuscular endings, where each group of endings was separated by ~ 370 μm in the rostro-caudal axis and projected 1.2 mm around the circumference. As spinal afferent axons bifurcated, their axons often showed dramatic reductions in diameter. Here, we identified in the distal colon, the characteristics of nerve endings that arise from single colorectal-projecting axons with cell bodies in DRG. These findings suggest that a population of sensory neurons in DRG can potentially detect sensory stimuli simultaneously via different morphological types of endings that lie in both colonic smooth muscle and myenteric ganglia.BACKGROUND Alzheimer's disease has chronic inflammatory components, which can be enhanced by systemic immune activation resulting in inflammation or vice versa. There is growing evidence that chronic periodontitis drives systemic inflammation and finally Alzheimer's disease. Thus, a link might exist between oral pathogens and Alzheimer's disease. This may be of special significance as there is an age-related incidence of chronic periodontitis. METHODS In this study, 20 consecutive patients with probable Alzheimer's disease were investigated. Diagnosis was established by cognitive tests, routine laboratory tests and cerebral magnetic resonance tomography. In 35% of these patients with cognitive impairment pathogenic periodontal bacteria were found. RESULTS The presence of Porphyromonas gingivalis, the key pathogen and one of the species involved in chronic periodontitis, was found to be associated with lower mini mental state examination scores (p  less then  0.05) and with a tendency to lower scores in the clock drawing test (p = 0.056). Furthermore, association between lower serum concentrations of the immune biomarker neopterin and the presence of Treponema denticola (p  less then  0.01) as well as of kynurenine were found in Alzheimer patients positive vs. negative for Tannerella forsytia (p  less then  0.05). CONCLUSIONS Data indicate a possible association of specific periodontal pathogens with cognitive impairment, Treponema denticola and Tannerella forsytia may alter the host immune response in Alzheimer's disease. Albeit still preliminary, findings of the study may point to a possible role of an altered salivary microbiome as a causal link between chronic periodontitis and cognitive impairment in Alzheimer's disease.BACKGROUND The 6 min pegboard and ring test (6PBRT) is a valid and reproducible test of unsupported arm exercise endurance. The aim of this study was to determine the associations between the 6PBRT, activities of daily living (ADL) and hemoglobin levels in chronic obstructive pulmonary disease (COPD). METHODS This study included 40 stable patients with COPD. All participants underwent the 6PBRT, peripheral venous blood sampling, arm ergometer test and the Glittre-ADL and ADL simulation tests for the ADLs performance. RESULTS An average 172.51 ± 25.94 rings were moved in 6 min. The number of rings in 6PBRT was significantly positively correlated with the number of cycles in ADL simulation test (r = 0.553, p  less then  0.001), peak oxygen consumption in arm ergometer (r = 0.381, p = 0.024) and serum hemoglobin level (r = 0.411, p = 0.011). CONCLUSION The number of rings moved in the 6PBRT is associated with ADL simulation test performance that reflects upper extremity ADLs. Therefore, the 6PBRT can be used for estimating limitation in upper extremity ADLs as a simple and quick evaluation in patients with GOLD stage II-III COPD.
