We studied the impact of residual renal function (RRF) on clinical outcome and quality of life in 61 patients on peritoneal dialysis (PD). They were assigned to two groups, at the time of initiation of PD, based on their estimated glomerular filtration rate (eGFR). The high RRF group had eGFR ≥5 mL/min/1.73 m[2] and the low RRF group hade GFR <5 mL/min/1.73 m[2]. All patients were followed up at regular intervals for clinical and biochemical variables. Baselines characteristics including age, sex, body mass index and cause of the kidney disease were similar in both groups...

Alveolar bone resorption caused by trauma or periodontal diseases has represented a challenge for both dental clinicians and researchers. In this study, we evaluate the osteogenic potential of human gingival fibroblasts (HGFs) through a direct transdifferentiation from HGFs to functional osteoblasts via epigenetic modification and osteogenic signaling with bone morphogenetic protein 2 (BMP2) in vitro and in vivo. HGF treatment with 5-aza-2'-deoxycytidine (5-aza-dC) induced demethylation in the hypermethylated CpG islands of the osteogenic lineage marker genes RUNX2 and ALP, and subsequent BMP2 treatment successfully drove the fibroblasts to the osteoblasts' lineage...

Employing cost-effective biomaterials to deliver chemically modified ribonucleic acid (cmRNA) in a controlled manner addresses the high cost, safety concerns, and lower transfection efficiency that exist with protein and gene therapeutic approaches. By eliminating the need for nuclear entry, cmRNA therapeutics can potentially overcome the lower transfection efficiencies associated with non-viral gene delivery systems. Here, we investigated the osteogenic potential of cmRNA-encoding BMP-9, in comparison to cmRNA-encoding BMP-2...

: The concept of macromers allows for a broad adjustment of biomaterial properties by macromer chemistry or copolymerization. Copolymerization strategies can also be used to introduce reactive sites for subsequent surface modification. Control over surface features enables adjustment of cellular reactions with regard to site and object of implantation. We designed macromer-derived polymer films which function as non-implantable analytical substrates for the investigation of surface properties of equally composed scaffolds for bone tissue engineering...

The Lnk adapter protein negatively regulates the signaling of thrombopoietin (TPO), the main megakaryocyte (MK) growth factor. Lnk-deficient (-/-) mice have increased TPO signaling and increased MK number. Interestingly, several mouse models exist in which increased MK number leads to a high bone mass phenotype. Here we report the bone phenotype of these mice. MicroCT and static histomorphometric analyses at 20 weeks showed the distal femur of Lnk(-/-) mice to have significantly higher bone volume fraction and trabecular number compared to wild-type (WT) mice...

High glucose (HG) is conceived to regulate bone metabolism in patients with diabetic mellitus (DM). In the present study, we examined the level of leukemia inhibitory factor (LIF), a pleiotropic cytokine in interleukin (IL)-6 family, in T2DM patients and investigated the regulation by HG on the induction of LIF/signal transducer and activator of transcription 3 (STAT3) signaling. Then we determined the regulation of HG and LIF on the osteoblast differentiation via measuring the ALP activity, matrix mineralization, and the expression of alkaline phosphatase (ALP), Runt-related transcription factor 2 (RUNX2), Osteocalcin (OCN) and osteopontin (OPN) in human osteoblast MG-63 cells...

A major limitation in current tissue engineering scaffolds is that some of the most important characteristics of the intended tissue are ignored. As piezoelectricity and high mechanical strength are two of the most important characteristics of the bone tissue, carbon nanotubes are getting a lot of attention as a bone tissue scaffold component in recent years. In the present study, composite scaffolds comprised of functionalized Multiwalled Carbon Nanotubes (f-MWCNT), medium molecular weight chitosan and β-Glycerophosphate were fabricated and characterized...

Biocompatibility, biodegradability and bioactivity are significantly important in practical applications of various biomaterials for bone tissue engineering. Herein, we develop a functional inorganic-organic hybrid system of calcium phosphate-phosphorylated adenosine (CPPA). Both calcium phosphate and phosphorylated adenosine molecules in CPPA are fundamental components in mammalians and play important roles in biological metabolism. In this work, we report our three leading research qualities: (1) CPPA hybrid microspheres with hollow and porous structure are synthesized by a facile one-step microwave-assisted solvothermal method; (2) CPPA hybrid microspheres show high doxorubicin loading capacity and pH-responsive drug release properties, and demonstrate positive therapeutic effects on six osteosarcoma cell lines in vitro and a mouse model of 143B osteosarcoma subcutaneous tumor in vivo; (3) CPPA hybrid microspheres are favorable to promote osteogenic differentiation of human bone mesenchymal stem cells (hBMSCs) by activating the AMPK pathway, with satisfactory evidences from cellular alkaline phosphatase staining, alizarin red staining, real time PCR and western analysis...

Desalination outflows frequently discharge brine containing coagulants and antiscalants (e.g. Iron-hydroxides and polyphosphonates) to the coastal environment. Here we examined changes in composition and productivity of natural microbial coastal communities in experimental mesocosms treated with either iron-hydroxide (Fe), polyphosphonate (Pn), or a combination of high salinities with both chemicals (All). Within 2 h of addition Fe already altered the microbial community composition, enhanced the bacterial production (BP) and cell specific production (BP/BA), and decreased primary production...
