HAnano® coated surface promoted comparable osseointegration as SLActive and TiUnite in the sheep model. The three tested surfaces showed comparable osseointegration at the early stages of low-density bone repair in the sheep model.
Cancer is a major health problem worldwide, and the most extensive treatment can be obtained by using chemotherapy in the clinic. However, due to the low selectivity of cancer cells, chemotherapy drugs produce a series of grievous side effects on normal cells.

In this research, we developed novel nanocarriers for magnetically targeted near-infrared (NIR) light-electromagnetic wave dual controlled drug delivery based on MgFe
O
@CuS nanoparticles (NPs) modified with aminopropyltriethoxysilane (APTES) in response to magnetic, NIR light, and electromagnetic wave irradiation. Synthesis and characterization of MgFe
O
@CuS-APTES NPs was carried out using X-ray diffraction measurements, scanning electron microscopy, transmission electron microscopy, photoluminescence emission spectra, UV-1800 spectrophotometer, N5230A vector network analyzer, MDS-6 microwave sample preparation system, and superconducting quantum interference device. In addition to that mentioned above, we also explored many other sides, such the first time as a new drug carrier for "location-timing-quantification" drug release with magnetic targeting and dual control of NIR light-electromagnetic waves.
Our findings indicate that multifunctional APTES modified MgFe2O4@CuS NPs could be used for the first time as a new drug carrier for "location-timing-quantification" drug release with magnetic targeting and dual control of NIR light-electromagnetic waves.
Niosomes, bilayer vesicles formed by the self-assembly of nonionic surfactants, are receiving increasing attention as potential oral drug delivery systems but the impact of niosomal formulation parameters on their oral capability has not been studied systematically. The aim of this study was to investigate the impact of surfactant composition and surface charge of niosomes in enhancing oral bioavailability of repaglinide (REG) as a BCS II model drug.

Niosomes (13 formulations) from various nonionic surfactants having HLB in the range of 4-28 (Tweens, Spans, Brijs, Myrj, poloxamer 188, TPGS and Labrasol) were prepared and characterized concerning their loading efficiency, hydrodynamic diameter, zeta potential, drug release profile, and stability. selleckchem The oral pharmacokinetics of the selected formulations were studied in rats (8 in vivo groups).

The results revealed that type of surfactant markedly affected the in vitro and in vivo potentials of niosomes. The C
and AUC values of REG after administration of the selected niosomes as well as the drug suspension (as control) were in the order of Tween 80> TPGS> Myrj 52> Brij 35> Span 60≈Suspension. Adding stearyl amine as a positive charge-inducing agent to the Tween 80-based niosomes, resulted in an additional increase in drug absorption and values of AUC and C
were 3.8- and 4.7-fold higher than the drug suspension, respectively.

Cationic Tween 80-based niosomes may represent a promising platform to develop oral delivery systems for BCS II drugs.

The aim of this study was to clinically evaluate
adhesion on titanium dioxide-coated stainless steel orthodontic wires to decrease white-spot formation.

In this study, four groups of 17 patients each (n=68) aged 12-25 years participated. A titanium dioxide coating layer was deposited on 0.4572 mm stainless steel orthodontic wires using physical vapor deposition. The coated wires were randomly assigned to one jaw, and the opposite jaw received an uncoated wire as control. Patients were divided into groups according to the duration that wires were in their mouths A) 1 week, B) 2 weeks, C) 3 weeks, and D) 4 weeks. Block randomization was used to assign patients to each group. At the end of the experiment, 20 mm of each wire (canine-to-canine area) was cut and cultured in
-specific medium. The culture plates were placed in an incubator containing 5% CO
for 72 hours at 37°C, and then colonies were counted. MTT was used to test the biocompatibility of the coated and uncoated wires. To evaluate the stabilertion.
Inhaled corticosteroids (ICS) are widely used and recommended to treat chronic obstructive pulmonary disease (COPD). While generally considered safe, several studies demonstrated an increased risk of pneumonia with the use of ICS in COPD patients. Although all ICS indicated for COPD carry the class labeling warning of increased pneumonia risk, evidence suggests an intraclass difference in the risk of pneumonia between inhaled budesonide and fluticasone. To date, systematic reviews of direct-comparison studies have not been performed to assess if an intraclass difference exists.

This review investigated whether there is an intraclass difference in risk of pneumonia between inhaled fluticasone and budesonide, the 2 most commonly used ICS in COPD.

A search of the medical literature was conducted in PubMed and Embase for the time period of 01/01/69-05/31/19. The search strategy combined terms that defined the patient/disease type, exposures, outcome, and the study/publication type. Descriptive and comparati.
There is likely a clinically important intraclass difference in the risk of pneumonia between fluticasone- and budesonide-containing inhaled medications in COPD.
In the Withdrawal of Inhaled Steroids during Optimized Bronchodilator Management (WISDOM) trial, inhaled corticosteroid (ICS) withdrawal in patients with chronic obstructive pulmonary disease receiving triple therapy (long-acting β
-agonist+long-acting muscarinic antagonist+ICS) did not change moderate/severe exacerbation risk. However, many patients were not taking triple therapy before study participation. This analysis was conducted to eliminate the impact of non-ICS users on WISDOM results by re-analyzing the data using only the subset of patients who were taking triple therapy at screening.

The effect of ICS withdrawal on moderate/severe exacerbation risk in the subgroup of WISDOM patients taking triple therapy before enrolling in the study was evaluated in this post hoc analysis. Additionally, the effect of ICS withdrawal in patients with a history of ≥2 exacerbations in the previous year and various blood eosinophil counts was assessed.

Overall, 39.0% (n=970 ICS continuation, 479; ICS withdrawal, 491) of the WISDOM trial population were taking triple therapy at screening.
