Hybrid basalt fiber (BF) and Talc filled high density polyethylene (HDPE) and co-extruded wood-plastic composites (WPCs) with different BF/Talc/HDPE composition levels in the shell were prepared and their mechanical, morphological and thermal properties were characterized. Incorporating BFs into the HDPE-Talc composite substantially enhanced the thermal expansion property, flexural, tensile and...

STUDY OBJECTIVE The ideal agent for producing pleurodesis has not been identified. Although talc is the agent most commonly used at the present time, there are concerns about its safety. Silver nitrate is a possible alternative agent. The purpose of the present study was to compare the effectiveness of intrapleural silver nitrate and talc slurry in producing pleurodesis in rabbits. Additionally...

The aim of this study was to review systematically the available evidence on pleurodesis for malignant effusion, focusing on the choice of the agents, route of delivery and other strategies to improve outcomes. Four electronic databases (MEDLINE, EMBASE, Web of Science and Cochrane Controlled Trials Register) were searched, reference lists checked and letters requesting details of unpublished t...

INTRODUCTION Malignant pleural effusions (MPEs) complicate many advanced malignancies and the median prognosis for those who develop MPEs is 6 months. These effusions lead patients to suffer from significant dyspnea, which may consequently impair mobility and lead to reduced quality of life. There are several treatment options for those with MPE. Thoracentesis may be quick and relatively easy t...

Objective: Symptomatic malignant pleural effusions are common sequelae in patients with certain malignancies. Pleurodesis via bedside thoracostomy is the current treatment option most commonly used. To our knowledge, this is the first prospective randomized trial to examine which agent, bleomycin or talc slurry, is superior in terms of effectiveness, safety, and cost. Patients and Methods: Betw...

Aluminum (Al) and Al alloys exhibit unusual passivity when immersed in alkaline lithium (Li) salt solutions. This passivity is a result of precipitation of a continuous, polycrystalline talc coating. Talc coatings persist when removed from the Li salt solution and offer increased corrosion protection during exposure to aggressive environments. Efforts to develop a low-cost, low-toxicity, easily...

AIM To determine the efficiency and safety of talc pleurodesis in treating the malignant pleural effusion and recurrent spontaneous pneumothorax. METHODS The study included 54 patients with malignant pleural effusion and recurrent spontaneous pneumothorax, who underwent talc pleurodesis using the "talc slurry" method of pleural talc obliteration. RESULTS Pleurodesis was successful in 52 (96...

The effect of individual and combined talc and glass fibers (GFs) on mechanical and thermal expansion performance of the filled high density polyethylene (HDPE) composites was studied. Several published models were adapted to fit the measured tensile modulus and strength of various composite systems. It was shown that the use of silane-modified GFs had a much larger effect in improving mechanic...

The morphology and miscibility of commercial poly(lactide) (PLA)/poly(b-hydroxybutyrate) (PHB, from 5 to 20 wt %) blends prepared by melt extrusion method, were investigated using differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR) observations. The results show that for all the studied blend contents, PLA/PHB blends are immiscible. The effects of PHB and ...

Geophysical observations including surface heat flow data indicate the subducting slab becomes fully coupled to overlying mantle wedge at ?70–80 km depth. This maximum depth of decoupling (MDD) separates cool, stagnant forearc from warmer, convecting capable generating arc magmas. Thermodynamic calculations demonstrate that talc is stable in H2O-undersaturated parts where its stability controll...
