The ultra-small superparamagnetic iron oxide (USPIO) particles with high saturation magnetization and good superparamagnetism were prepared by reverse micro-emulsions using novel C16E15 as surfactant, which can reduce magnetic dipole-dipole interaction, hence decreasing the critical blocking temperature (TB). Powder X-ray diffraction (XRD), Infrared spectrum (FT-IR), Transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), and Vibrating sample magnetometer (VSM) were used to characterize the magnetic particles...

The standard of care for locally advanced cervical cancer has been the combination of a taxane with platinum based therapy. Conventional docetaxel is known to cause hypersensitivity reactions, fluid retention and other toxicities due to polysorbate-80 and ethanol. Corticosteroid premedication prior to docetaxel administration is required to prevent these toxicities, however, toxicities are still observed, sometimes fatal, despite premedication. DoceAqualip, a nanosomal docetaxel lipid suspension, developed with lipids generally regarded as safe (GRAS) by the US Food and Drug Administration, is devoid of polysorbate-80 and ethanol...

BACKGROUND: Eosinophils play a central role in the propagation of allergic diseases including asthma. Both recruitment and retention of eosinophils regulate pulmonary eosinophilia but the question of whether alterations in apoptotic cell clearance by phagocytes directly contributes to resolution of allergic airway inflammation remains unexplored. OBJECTIVES: In this study we investigated the role of the receptor tyrosine kinase Mer in mediating apoptotic eosinophil clearance and allergic airway inflammation resolution in vivo in order to establish whether apoptotic cell clearance directly impacts upon the resolution of allergic airway inflammation...

The study was performed on pregnant women with a gestational age of 26-32 weeks of pregnancy, who had been admitted to the hospital with a confirmed diagnosis of premature rupture of membranes. In all eligible women, ultrasounds were performed for the evaluation of amniotic fluid index. Then, the women were divided into two groups according to amniotic fluid index of ≥5 cm and <5 cm. These women were followed and monitored up to delivery. The women of the two groups did not have significant difference between them according to age, gestational age at the time of ruptured membrane, body mass index, gravidity, parity, gestational age at delivery and route of delivery...

Liquid-infused membranes inspired by slippery liquid-infused porous surfaces (SLIPS) have been recently introduced to membrane technology. The gating mechanism of these membranes is expected to give rise to anti-fouling properties and multi-phase transport capabilities. However, the long-term retention of the infusion liquid has not yet been explored. To address this issue, we investigate the retention of the infusion liquid in slippery liquid-infused membranes (SLIMs) via liquid-liquid displacement porometry (LLDP) experiments combined with microscopic observations of the displacement mechanism...

All-hydrocarbon stapled peptides are a promising class of protein-protein interaction regulators; their potential therapeutic benefit arises because they have high binding affinity and specificity to intracellular molecules. The cell permeation efficacy of these peptides is a critical determinant of their bioactivity. However, the factors that determine their cellular uptake remain an active area of research. In this study, we evaluated the effect of stapled (or cross-linked) formation on the cellular uptake of six known all-hydrocarbon stapled peptides...

Natriuretic peptides (NP) are widely recognized as key regulators of blood pressure, water and salt homeostasis. In addition, they play a critical role in physiological cardiac growth and mediate a variety of biological effects including antiproliferative and anti-inflammatory effects in other organs and tissues. The cardiac release of NPs ANP and BNP represents an important compensatory mechanism during acute and chronic cardiac overload and during the pathogenesis of heart failure where their actions counteract the sustained activation of renin-angiotensin-aldosterone and other neurohormonal systems...

The mono-PEGylated recombinant human interleukin-11 (rhIL-11) was evaluated for its pharmacology and toxicology profile in non-human primates. This PEGylated IL-11 (PEG-IL11) showed a much prolonged circulating half-life of 67h in cynomolgus monkeys as compared to its un-PEGylated counterpart (~3h) through subcutaneous administration, implicating that a single injection of the recommended dose will effectively enhance thrombopoiesis in humans for a much longer period of time compared to rhIL-11 in humans (t1/2=6...

Connexin43 mimetic peptide (Cx43MP) has been intensively investigated for its therapeutic effect in the management of inflammatory eye conditions, spinal cord injury, wound healing and ischemia-induced brain damage. Here, we report on a validated stability-indicating reversed-phase high performance liquid chromatography (RP-HPLC) method for the quantification of Cx43MP under stress conditions. These included exposure to acid/base, light, oxidation and high temperature. In addition, the degradation kinetics of the peptide were evaluated in bovine vitreous and drug-free human plasma at 37 °C...

A 3D computational modeling study of the deposition dynamics of rod-shaped colloids during transport in porous media under favorable conditions (no energy barrier to deposition) was presented. The objective was to explore the influences of particle shape on colloid transport and retention. During the simulation, both translation and rotation of ellipsoidal particles were tracked and evaluated based on an analysis of all the forces and torques acting on the particle. We observed that shape was a key factor affecting colloid transport and attachment...

Herein, we propose the fabrication of a new carrier with core/shell structure-inner core of cellulose acetate (CA) coated by a micrometric layer of chitosan (CS)-fabricated through an integrated process, which combines Electro Dynamic Atomization (EDA) and layer-by-layer (LbL) technique. We demonstrate that CA based microspheres possess a unique capability to relevantly retain the drugs-that is, Ketoprofen Lysinate (KL)-along the gastric tract, while providing a massive release along the intestine. CS shell slightly influences the morphology and water retention under different pH conditions, improving drug encapsulation without compromising drug release kinetics...

The clinical effect of prednisone in metastatic castration-resistant prostate cancer (mCRPC) is unknown. We performed a pooled analysis of control arms of randomized controlled trials that had or had not administered single-agent prednisone. Randomized controlled trials with a control arm that included single-agent placebo (or no anticancer therapy) or single-agent prednisone (with or without placebo) were eligible for analysis. Patients receiving prednisone combined with other agents in the control arm were excluded...

In the last few years new oral contraceptives have been marketed showing a better safety profile for women. They are the result of important changes made to the old compounds. As far as the estrogenic component, with the aim of decreasing side effects, the dose of ethinyl estradiol has been reduced and synthetic estrogens have been replaced by natural estradiol, further improving the safety profile. Also the progestin component in the last years has been changed in terms of dose, endocrine and metabolic characteristics...

BACKGROUND: Lymphoscintigraphy is commonly used to assess breast cancer-related lymphedema. However, a reliable quantitative method that clearly distinguishes normal lymphatic function from lymphedema is desired. We propose a quantitative method based upon the physiological mean transit time (MTT) measure of lymph fluid passing through the arm. METHODS AND RESULTS: Eleven patients, aged 34-68 years, with unilateral arm lymphedema following breast cancer treatment underwent simultaneous bilateral lymphoscintigraphy using intradermal injection of 99mTc-labeled human serum albumin (HSA)...

Sterile filters are ubiquitous in biopharmaceutical manufacturing processes. Since such filters are in direct contact with the process fluid, profiling of the extractables is of utmost importance. The work presented here reveals the extractables profile from filter cartridges for sterilizing grade filtration, which were obtained from six different vendors. All filters contain a 0.2 μm polyethersulfone (PES) membrane for sterile filtration combined with a PES pre-filter with retention rates spanning from 0...

Six chiral pesticides containing chiral sulfur/phosphorus atoms were separated by supercritical fluid chromatography with supercritical CO2 as the main mobile phase component. The effect of the chiral stationary phase, different type and concentration of modifiers, column temperature, and backpressure on the separation efficiency was investigated to obtain the appropriate separation condition. Five chiral pesticides (isofenphos-methyl, isocarbophos, flufiprole, fipronil, and ethiprole) were baseline separated under experimental conditions, while isofenphos only obtained partial separation...
