In this study, a novel macroporous composite biomaterial consisting of gelatin-hydroxyapatite-calcium sulphate for delivery of bone morphogenic protein-2 (rhBMP-2) and zoledronic acid (ZA) has been developed. The biomaterial scaffold has a porous structure and functionalization of the scaffold with rhBMP-2 induces osteogenic differentiation of MC3T3-e1 cells seen by a significant increase in biochemical and genetic markers of osteoblastic differentiation. In-vivo muscle pouch experiments showed higher mineralization using scaffold+rhBMP-2 when compared to an approved absorbable collagen sponge (ACS)+rhBMP-2 as verified by micro-CT...

Voltage-gated Na+ currents (INa), known to contain many components (e.g., transient, resurgent and persistent INa) with unique gating properties, are involved in the generation and propagation of action potentials in excitable cells. In this study, how tefluthrin (Tef), a synthetic pyrethoid, and telmisartan (TEL), blocker of angiotensin II receptors can perturb those components of INa was investigated. The presence of either Tef or TEL increased the values of the gating charges of INa involved in the activation (za) and inactivation (za)...

We report an exciting behavior of H-shaped single layer graphene structures subject to a heat flux. H-shaped graphene structures with certain particular dimensions were observed to be able to establish coherent mechanical vibrations in the out-of-plane direction directly from a steady state heat flux flowing from the centerline of the structure towards the two ends. Molecular dynamics (MD) simulation methods together with phonon spectral energy density (SED) analysis techniques were used to obtain the phonon dispersion profiles and identify the low frequency high energy phonon modes...

Unlike low tumorigenic bulk tumor cells (non-CSCs), cancer stem cells (CSCs) are a subset of tumor cells that can self-renew and differentiate into different cancer subtypes. CSCs are considered responsible for tumor recurrence, distant metastasis, angiogenesis, and drug or radiation resistance. CSCs also are resistant to apoptosis. Zoledronic acid (ZA) is a third generation bisphosphonate that reduces cell proliferation and exhibits anti-tumor effects by inducing cell death in some malignancies; however, the effects of ZA on CSCs are unclear...

Oxidative burst, release of reactive oxygen species/reactive nitrogen species (ROS/RNS) contributed to microorganisms killing, is a vital immune response of crustacean haemocyte. Three morphologic haemocyte types (hyaline cells, HC; semigranular cells, SGC; granular cells, GC) have been defined in crustaceans, and found to play different roles in immune defense. However, oxidative burst activities of different haemocyte subpopulations in crustaceans are currently not documented. In the present study, we investigated the oxidative burst activities of the three haemocyte types in the freshwater prawn Macrobrachium rosenbergii using the common ROS fluorescent probe dichlorofluorescin-diacetate (DCFH-DA)...

Osteoporosis presents a challenge to the long-term success of osseointegration of endosseous implants. The bio-inspired 3,4-dihydroxy-L-phenylalanine (Dopa) coating is widely used as a basic layer to bind osteogenetic molecules that may improve osseointegration. To date, little attention has focused on application of Dopa alone or binding inhibitors of bone resorption in osteoporosis. Local use of a bisphosphonate such as zoledronic acid (ZA), an inhibitor of osteoclast-mediated bone resorption, has been proven to improve implant osseointegration...

Over 100 types of congenital disorders of glycosylation (CDG) have been reported and the number is rapidly increasing. However, each type is very rare and is problematic to diagnose. Mannosyl-oligosaccharide glucosidase (MOGS)-CDG (CDG type IIb) is an extremely rare CDG that has only been reported in three patients from two unrelated families. Using targeted exome sequencing, we identified another patient affected by this condition. This patient had increased serum trisialotransferrin levels. Importantly, a review of the features of all four patients revealed the recognizable clinical hallmarks of MOGS-CDG...

BACKGROUND: Bisphosphonate-related osteonecrosis of the jaws (BRONJ) is a complication of the bisphosphonate (BP) treatment and its pathopysiology is still not fully understood. The existing preventive and treatment options require updates and more attention. Geranylgeraniol (GGOH) so far demonstrated an increased activity and viability of the cells previously treated with zoledronic acid (ZA). The aim of this study was to evaluate the in vivo effects of GGOH on the development of BRONJ...

We performed a retrospective analysis of 88 adult patients with B-ALL diagnosed in our center by a flow-cytometric assessment. Immunophenotypic expression of leukemic cells was explored by simultaneous evaluation of positivity, percentage of expressing cells and median fluorescence intensity (MFI). Presence of BCR/ABL1 fusion transcripts were assessed by RT-PCR analysis and were identified in 36 patients (40.9%). CD10 and CD34 were positive in the totality of BCR/ABL1-positive cases. Patients with gene rearrangement had a greater frequency of CD66c, CD13 and CD33 positivity compared with BCR/ABL1-negative cases...

Using the universal structure predictor algorithm, we proposed that two-dimensional MnB structures with p4mmm (α-MnB) and pmma (β-MnB) symmetries could be synthesized. This finding was verified by calculating the dynamical stability, molecular dynamics, and mechanical properties. The α-MnB had an in-plane stiffness Y x (=Y y ) around 100 N/m while the β-Mn displayed an asymmetric mechanical stiffness of Y x  = 186 N/m and Y y  = 139 N/m. Both systems displayed a ferromagnetic ground state with metallic band structures...

Compound 1 was designed and prepared as a heteroditopic ion-pair receptor that contains two urea groups for anion complexation and N-benzyl-18-crown-6 for cation recognition. These ion-binding domains are assembled together by the l-ornithine scaffold. Qualitative cation coordination studies of receptor 1, supported by quantitative data received for monotopic N-(3-nitrobenzyl)-aza-18-crown-6 (3a), have shown that 1 has a strong affinity for Na+, K+ and NH4+ cations. Anion binding studies revealed that in the absence of cations coordinated to 1 (TBA salts), anions are bound with a relatively moderate strength with the selectivity: BzO- > AcO- > Cl-> NO2- > Br-...

REVIEW
Sasigarn A Bowden, John D Mahan
Zoledronic acid (ZA), a highly potent intravenous bisphosphonate (BP), has been increasingly used in children with primary and secondary osteoporosis due to its convenience of shorter infusion time and less frequent dosing compared to pamidronate. Many studies have also demonstrated beneficial effects of ZA in other conditions such as hypercalcemia of malignancy, fibrous dysplasia (FD), chemotherapy-related osteonecrosis (ON) and metastatic bone disease. This review summarizes pharmacologic properties, mechanism of action, dosing regimen, and therapeutic outcomes of ZA in a variety of metabolic bone disorders in children...

Phonon transport in group-VA element (As, Sb and Bi) monolayer semiconductors has been widely investigated in theory, and, of them, monolayer Sb (antimonene) has recently been synthesized. In this work, phonon transport in monolayer SbAs is investigated with a combination of first-principles calculations and the linearized phonon Boltzmann equation. It is found that the lattice thermal conductivity of monolayer SbAs is lower than those of both monolayer As and Sb, and the corresponding sheet thermal conductance is 28...
