Osteoporosis induction in a sheep model by steroid administration combined with ovariectomy recapitulates decreased bone formation and substandard matrix mineralization in patients. Recently, the role of osteocytes has been frequently addressed, with focus on their role in osteoclastogenesis. However, the quantification of receptor activator of NF-κB ligand (RANKL) and osteoprotegerin (OPG) signaling in osteocytes was not studied in sheep. The current study reproduced the sheep model of osteoporosis to study the RANKL/OPG ratio correlation to the method of osteoporosis induction...

In the present work, new self-assembled nanoparticles (NPs) were engineered using biocompatible and biodegradable natural polymer, chitosan (CS). The complexation of CS with sodium dodecyl sulfate (SDS) facilitated the regioselective chemical modification of CS hydroxyl groups with maleic anhydride, and produced polymerizable precursor of CS that was further grafted with N-isopropylacrylamide (NIPAAm) as temperature-sensitive moiety and oleic acid (OA) as hydrophobic monomer. After removal of SDS complex, the free amino groups were functionalized with folic acid (FA) to form folate-(PNIPAAm-co-OA)-g-CS micellar NPs...

Bone loss varies according to disease and age and these variations affect bone cells and extracellular matrix. Osteoporosis rat models are widely investigated to assess mechanical and structural properties of bone; however, bone matrix proteins and their discrepant regulation of diseased and aged bone are often overlooked. The current study considered the spine matrix properties of ovariectomized rats (OVX) against control rats (Sham) at 16 months of age. Diseased bone showed less compact structure with inhomogeneous distribution of type 1 collagen (Col1) and changes in osteocyte morphology...

Recurrent mutations in isocitrate dehydrogenase 2 (IDH2) occur in ~12% of patients with acute myeloid leukemia (AML). Mutated IDH2 proteins neomorphically synthesize 2-hydroxyglutarate resulting in DNA and histone hypermethylation, leading to blocked cellular differentiation. Enasidenib (AG-221/CC-90007) is a first-in-class, oral, selective inhibitor of mutant-IDH2 enzymes. This first-in-human, phase 1/2 study assessed the maximum tolerated dose (MTD), pharmacokinetic and pharmacodynamic profiles, safety, and clinical activity of enasidenib in patients with mutant-IDH2 advanced myeloid malignancies...

In the present paper, porcine pancreas lipase (PPL) was immobilized to a new version of magnetite via a novel stepwise dithiocarbamate/chitosan-based method in alternation to glutaraldehyde. Magnetic chitosan nanocomposite was post-modified to produce dithiocarbamate moieties on the surface through amine functions. Then, immobilization of lipase was successfully achieved on the surface of magnetically separable Fe3O4@CS/NHCS2H via a post-modification. Each step of immobilization was carefully monitored by characterization and all were successfully proved...

BACKGROUND AND STUDY AIMS: Gastro-oesophageal reflux disease (GERD) is incriminated as a cause of non-asthmatic infantile wheeze. To date, no diagnostic test is considered standard for GERD-related airway reflux diagnosis. Oesophageal combined multiple channel intraluminal impedance and pH (MII-pH) monitoring is proposed to be a sensitive tool for evaluation of all GERD including infantile wheeze. We aimed to determine the GERD prevalence amongst wheezy infants in the first year of life using combined MII-pH versus pH monitoring alone and evaluate the sensitivity and specificity of objective MII-pH monitoring parameters in GERD-associated infantile wheeze diagnosis compared to those of lipid-laden macrophage index (LLMI)...

In this study, the ability of oxidized phenolic compounds of tannic, gallic, ferulic and caffeic acids to crosslink gelatin (G) was investigated. The electrospun crosslinked gelatin nanofibers were assessed in terms of gelatin solution properties, fiber morphology, thermal properties, FTIR spectra, XRD pattern and antioxidant activity. Tannic acid showed the most crosslinking activity towards gelatin (13.3 vs 7.44, 4.65, and 3.45% for caffeic, gallic and ferulic, respectively). Crosslinking enhanced roughly electrical conductivity of gelatin solution while the surface tension and viscosity reduced...

INTRODUCTION: Peri-implantitis is an inflammatory process, characterized by loss of bone around implants and bleeding on probing. Colonization of bacteria in the pocket created around the implant is one of the most important aetiologic factors involved. Although antibiotics are routinely used and are effective agents against this bacterial infection, due to the side effects and drug resistance of these medications, researchers are more interested in using herbal derivatives. There are relatively limited number of studies in this respect...

Recent physiological studies indicated that S. lividans metabolism was mainly glycolytic, whereas S. coelicolor metabolism was mainly oxidative. To determine whether such metabolic characteristics were correlated with consistent proteomics features, a comparative label-free, shotgun proteomics analysis of these strains was carried out. Among 2024 proteins identified, 360 showed significant differences in abundance between the strains. This study revealed that S. coelicolor catabolized glucose less actively than S...
