632). No correlation was observed between the thrombocyte value and the traumatic tap (p = 0.891). The ratio of the traumatic tap was not significant between the patient groups with a platelet count of ≥50.000/mm
or <50.000/mm
(p = 0.418). After adding the transfused patients, the traumatic tap ratio remained nonsignificant between the two groups (p = 0.851).
Hemorrhagic complications were rare in the thrombocytopenic patients who received IT CT after the LP procedure applied by experienced specialists. However, further prospective large studies evaluating the safety of procedures in thrombocytopenic patients are needed to make clear conclusion.

Herein, a polyethylenimine (PEI) derivative, N-isopropylacrylamide-modified PEI (namely PEN), was constructed through Michael addition and then employed as a carrier for miR-29a transfection. The carrier PEN has been demonstrated to possess favorable ability to condense miR-29a into stable nanoparticles and protect miR-29a against the nuclease degradation, using agarose gel retardation assay. Meanwhile, PEN exhibited excellent efficiency in miR-29a transfection demonstrated by flow cytometry and confocal laser scanning microscope. check details Further, the PEN-mediated miR-29a transfection could achieve an obvious anti-proliferative effect owing to the activation of cell apoptosis and the cell cycle arrest at G1 phase, using human lung adenocarcinoma cell line A549 as a model. In addition, PEN/miR-29a nanoparticles could suppress the migration and invasion of cancer cells measured by wound healing and Transwell migration assays. Overall, the PEN-mediated miR-29a transfection could be potentially employed as a useful approach to achieve cancer gene therapy.Metallic materials made of rather precious alloys are widely used in orthopedic surgery, circulatory system, and dentistry fields. Stainless steel coated by alloys with a variety of physiochemical properties can be an excellent candidate for making economical devices with superior biomedical compatibility. In this study, a Fe- based metallic glass alloy was applied on 316L stainless steel (316L SS) using the electro-spark deposition (ESD) method as an economic and easy handling method. The coated samples were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and atomic force microscopy (AFM). It was found that a metallic glass coating was uniformly formed on the stainless steel substrate. Cytocompatibility (MTT assay), hemocompatibility, and cell attachment assays of the fabricated biomaterials were carried out using bone and connective tissue cell lines. The samples with optimized coating were shown to exert lower cytotoxicity, better cell attachment, and higher blood compatibility than the stainless steel substrates.In recent years, nanomaterials have been widely used in consumer products. High reactivity of metallic nanoparticles and its bioaccumulation in biological systems are the main causes of concern over their safety to human health and environment. The available information related to the safety of several nanomaterials is insufficient. Hematite nanoparticles are proposed for various applications. Ecotoxicological studies of hematite nanoparticles are very limited. In the present study, biosynthesised hematite nanoparticles using Bacillus cereus were evaluated for its acute oral toxicity in mice following OECD guidelines. A dose of 2 g/kg/p.o was administered to Swiss albino mice through gastric oral feeding tube and observed for 14 days. After two weeks blood samples were collected and subjected for evaluation of haematological parameters and biochemical analysis. There was no mortality and toxic signs of animals till the end of observational period. The animals were sacrificed and organs like liver and kidneys were isolated to study the histopathological changes. The results of the study revealed that there was no drastic change in parameters except slight change in bilirubin in the hematite nanoparticle treated mice. Biosynthesised hematite nanoparticles were assayed for toxicity in Artemia salina. Cysts treated with higher concentrations of hematite nanoparticles showed small sized nauplii. Biosynthesised hematite nanoparticles were found to be non-toxic to A. salina nauplii in lower concentrations.Cellular responses can be regulated and manipulated through combining stimuli-responsive biomaterial with external stimulus. In this present, the magneto-responsive CoFe2O4/P(VDF-TrFE) nanocomposite coatings were designed to understand cell behaviors of preosteoblasts, as well as get insight into the underlying mechanism of osteogenic differentiation under static magnetic field (SMF). CoFe2O4/P(VDF-TrFE) nanocomposite coatings with differential magnetic property (low, medium and high magnetization) were prepared by incorporation of different mass fraction of CoFe2O4 nanoparticles (6%, 13 %, 20 %) into P(VDF-TrFE) matrix. Cell experiments indicated that all nanocomposite coatings with the assistance of SMF could promote the cell attachment, proliferation and osteogenic differentiation of MC3T3-E1 cells. Among different nanocomposite coatings, low magnetization coating (6%) showed a higher ALP activity and gene expression of Runx2, Col-I, OCN. Molecular biology assays demonstrated that the combination of nanocomposite coatings and SMF could significantly up-regulate the expression level of α2β1 integrin and p-ERK. Whereas, the addition of inhibitor U0126 down-regulated sharply the expression level of p-ERK, which indicated that cellular osteogenic differentiation of MC3T3-E1 cells was governed through α2β1 integrin-mediated MEK/ERK signaling pathways during CoFe2O4/P(VDF-TrFE) nanocomposite coatings were combined with SMF. This work provided a promising strategy to enhance cellular osteogenic differentiation through a remote-control manner, which exhibited great potential in the application of bone tissue repair and regeneration.
