MicroRNA-126 regulates HOXA9 by binding to the homeobox
The PicTar program predicted that microRNA-126 (miR-126), miR-145, and let-7s target highly conserved sites within the Hoxa9 homeobox. There are increased nucleotide constraints in the three microRNA seed sites among Hoxa9 genes beyond that required to maintain protein identity, suggesting additional functional conservation. In preliminary experiments, forced expression of these microRNAs in ...

Investigation of the low-dose γ-irradiation effect on the spontaneous and high-dose radiation-induced level of cytogenetic damage in mouse bone marrow cells in vivo
The effect of low-dose gamma-irradiation (0.1 or 0.2 Gy with a dose rate of 0.125 Gy/min) of mice on the spontaneous and high-dose radiation-induced level of cytogenetic damage during ageing of animals was studied using the micronucleus test. It was shown that a single low dose of gamma-radiation induces a cytogenetic adaptive response in mouse bone marrow cells, which persists for up to 12 ...

Enhancing low cost stainless steel implants: bioactive silica–based sol–gel coatings with wollastonite particles
A hybrid organic–inorganic sol–gel coating with the addition of wollastonite particles is used as a potential solution to improve performance of low cost AISI 316L stainless steel. This work is focused on characterising the coatings by studying their synthesis and deposition, electrochemical, and in vitro and in vivo response. The coated implants presented in vitro Ca/P–rich ...

Study of delayed effects induced by accelerated 12C ions with an energy of 200 MeV/n and X-rays on mice in vivo
In the present work, we investigated the delayed effects induced by accelerated 12C ions with energy of 200 MeV/n and X-rays on mice. Dose dependence, ability of the adaptive response (AR) induction and genomic instability in F1 generation were studied by the micronucleus test in polychromatic erythrocytes in bone marrow. Irradiation by carbon ions with doses of 0.1, 0.2, 0.5, 1 and 1.5 Gy was ...

Infrared spectroscopy of human bone marrow: evidence of structural changes during acute leukemia
Fourier transform infrared (FTIR) spectroscopy was explored as a means to distinguish newly diagnosed of acute lymphoblastic leukemia from disease free bone marrow samples. Characteristic bands alterations were identified in both healthy and diseased samples arising from cellular protein, lipid and DNA. There were specific changes that affected the secondary structure of proteins that appeared in ...

The 3rd AIDS patient is "cured"! Has mankind finally conquered AIDS?
At an academic conference on Feb 15, U.S. experts announced the world's first female AIDS "cure," making it the third case of HIV infection to be cured. After therapy and withdrawal of antiviral drugs, HIVs were not identified in the patient's body for more than 14 months, indicating that the virus was in complete remission, according to academics. The key to this patient's recovery was a blood ...

Unveiling The Manifold Potentials: Mesenchymal Stem Cells & Bone Marrow Mesenchymal Stem Cells
In the vibrant realm of cellular biology and regenerative medicine, mesenchymal stem cells (MSCs) hold unparalleled potential for therapeutic applications. Particularly noteworthy are bone marrow mesenchymal stem cells (BM-MSCs), a subtype of MSCs. Their unique properties make them indispensable resources for developing ground-breaking solutions for various medical conditions. Mesenchymal stem ...

Protection of gastrointestinal and haematopoietic systems by ascorbic acid-2-glucoside in mice exposed to whole-body gamma radiation
Whole-body exposure of mice to gamma radiation leads to depletion of tissue antioxidant defence and damages the haematopoietic and gastrointestinal systems in mice. Administration of ascorbic acid-2-glucoside (AsAG) at a dose of 100 mg/kg body weight could prevent the radiation-induced reduction of total White Blood Cell (WBC) count and decrease in bone marrow viability following whole-body ...

What is the meaning of neoplastic disease?
Neoplasia is the abnormal growth and proliferation of abnormal cells or abnormal amounts of cells due to a benign or malignant process. There can be benign tumors, or neoplasms, and malignant ones. Remember that it's the malignant tumors, or cancer, that can metastasize, which is when cancer spreads around the body. Leukemia is used for lymphoid neoplasms presenting with widespread involvement ...

Inhibition of apoptosome formation by suppression of hsp90β phosphorylation in tyrosine kinase-induced leukemias
Constitutively active tyrosine kinases promote leukemogenesis by increasing cell proliferation and inhibiting apoptosis. However, mechanisms underlying apoptotic inhibition have not been fully elucidated. In many settings, apoptosis occurs by mitochondrial cytochrome c release, which nucleates the Apaf-1/caspase-9 apoptosome. Here we report that the leukemogenic kinases, Bcr-Abl, FLT3/D835Y, and ...

Fabrication Of In-Vitro Phenotypically Stable Engineered Articular Cartilage
Researchers from IRCCS Istituto Ortopedico Rizzoli and Indian Institute of Technology, Delhi (IIT) used their REGENHU bioprinters to fabricate an in vitro phenotypically stable engineered articular cartilage by embedding human bone marrow-derived stromal cells (hMSCs) in a cell-laden silk fibroin–gelatin (SF-G) bioink. The bioprinted constructs allowed the in vitro study of chondrogenic ...

Health monitoring of NPP workers
The aim of the study is to assess the health status of Kozloduy Nuclear Power Plant personnel in association with their occupational exposure to low doses of ionising radiation (IR) as well as with other factors of their working environment and to determine the probability of the occupational exposure to be a reason for the diagnosed malignant diseases (Probability of Causation – PC). More than ...

A New Concept of Mosaicplasty: Autologous Osteoperiosteal Cylinder Graft Covered With Cellularized Scaffold
Abstract: A concern regarding osteochondral autograft transfer for chondral defects is donor-site morbidity of the knee, the most common source of the autograft. To avoid the drawbacks of osteochondral autograft transfer, a cylindrical osteoperiosteal graft harvested from the iliac crest covered by a same-sized cylinder of hyaluronic acidebased polymer scaffold pretreated with bone marrow ...

Preclinical and safety studies of V-1 Immunitor
The safety of V-1 Immunitor (V1) has been investigated. L929; BHK; Vero; Caco-2 and CEM-SS cells have not shown cytotoxicity even at 10 mg/ml dose. Ames' mutagenicity and micronucleus genotoxicity tests came out negative at 50 mg and 2000 mg/kg doses in Salmonella and bone marrow of IRC mice. Acute and chronic dosing of V1 to Swiss albino mice and Spague Dawley rats failed to cause any deaths. ...
