High-expansion polypropylene foam prepared in non-crystalline state and oil adsorption performance of open-cell foam.

The preparation of high-expansion open-cell foam for oil spill clean-ups is important, but still challenging with linear isotactic polypropylene (PP). Therefore, a cooling batch foaming method was designed to fabricate the high-expansion PP foams using supercritical CO as a blowing agent. To investigate the relation between the crystallization and foaming of PP, an in-situ visualization system was employed. It is found that the CO dissolved in polymer melt depresses the crystallization temperature and nucle...


Rapid degradation of malachite green by CoFeO-SiC foam under microwave radiation.

This study demonstrated rapid degradation of malachite green (MG) by a microwave (MW)-induced enhanced catalytic process with CoFeO-SiC foam. The catalyst was synthesized from CoFeO particles and SiC foam by the hydrothermal method. X-ray diffraction and scanning electron microscopy techniques were used to confirm that CoFeO particles were settled on the surface of SiC foam. In this experiment, a novel fixed-bed reactor was set up with this catalyst for a continuous flow process in a MW oven. The different ...

Can pulmonary foam arise after postmortem submersion in water? An animal experimental pilot study.

It is difficult to differentiate drowning from postmortem submersion. Pulmonary foam can be found in bodies retrieved from water. It is unknown whether foam is a result of drowning or if it also forms after postmortem submersion. We divided deceased piglets into three groups: postmortem saltwater submersion (N = 20), postmortem freshwater submersion (N = 20) and dry-land controls (N = 20). All carcasses underwent endoscopic examination within 24 h of death and the presence of external and inte...

Forty-five Years of Foam: A Retrospective on Air Sampling with Polyurethane Foam.

Genetic diversity of porcine circovirus type 2 in China between 1999-2017.

Porcine circovirus type 2 (PCV-2), is linked to PCV-2 associated disease, which has caused considerable economic loss in the swine industry. Here, we report the genetic diversity of PCV-2 in China. A total of 74 Chinese PCV-2 strains sequenced between 1999 and 2017 were studied. Based on the ORF2 and complete genomes, we found that apart from the PCV-2a, PCV-2b, and PCV-2d genotypes, two unstable recombination genotypes also exist, referred to as IM1 and IM2 genotypes. We found that the patterns of PCV-2 ge...

Humanitarianism from Below: Sowa Rigpa, the Traditional Pharmaceutical Industry, and Global Health.

In this article I explore, for the first time, the relationship between Sowa Rigpa (Tibetan medicine) and global health, tracing "the global" in ethical discourses and pharmaceutical innovation practices of Tibetan medical practitioners. I argue that Sowa Rigpa's engagement with the world and its global health activities outside China can be understood as a form of "humanitarianism from below," while its industrialization in China aligns with global health in different ways. In providing new insights into r...

Storage lipid studies in tuberculosis reveal that foam cell biogenesis is disease-specific.

Foam cells are lipid-laden macrophages that contribute to the inflammation and tissue damage associated with many chronic inflammatory disorders. Although foam cell biogenesis has been extensively studied in atherosclerosis, how these cells form during a chronic infectious disease such as tuberculosis is unknown. Here we report that, unlike the cholesterol-laden cells of atherosclerosis, foam cells in tuberculous lung lesions accumulate triglycerides. Consequently, the biogenesis of foam cells varies with t...

Effect of dual modification on properties of biodegradable crosslinked-oxidized starch and oxidized-crosslinked starch films.

Due to poor properties of biodegradable native starch (NS) film; in this work, dual-modified starch films i.e. crosslinked-oxidized starch (C-OS) and oxidized-crosslinked starch (O-CS) films were prepared and compared to single-modified starch i.e. crosslinked starch (CS) and oxidized starch (OS) films. All modified starch films were oxidized and crosslinked using hydrogen peroxide and boric acid by casting technique. Degree of crystallinity and swelling behavior of both dual-modified starch films were foun...

Silencing LAIR-1 in human THP-1 macrophage increases foam cell formation by modulating PPARγ and M2 polarization.

Formation of macrophage-derived foam cells may mark the initial stages of atherosclerosis. We investigated the association between the expression of the leukocyte-associated immunoglobulin-like receptor 1 (LAIR-1) in macrophages and foam cell formation. A foam cell model was established by incubating THP-1-derived macrophages and bone marrow macrophages (BMMs) with oxidized low-density lipoprotein (ox-LDL). The role of LAIR-1 in foam cell formation was evaluated via Oil Red O staining and Dil-ox-LDL fluores...

By considering the literature of Curcumae Radix, a multi-source Chinese herb and the situation of market investigation, the modern evaluation method based on traditional grading was introduced for comprehensive evaluation of the processed Curcumae Radix. The correlation between traditional grading me...

Porous cobalt oxides/carbon foam hybrid materials for high supercapacitive performance.

Porous cobalt oxides/carbon foam hybrid materials (CoO/C) was prepared by a solvothermal method. Owing to the heredity of the interconnected hierarchical porous structure from the carbon foam, the obtained CoO/C composites had a larger specific surface area and a wider pore size distribution than CoO, which facilitated the electron and ion transport. Benefiting from the synergistic contribution of CoO nanoparticles and the porous carbon foam, CoO/C possessed an excellent supercapacitive performance. When th...

Trends and Predictors of Retweets in Free Open Access Medical Education (#FOAMed) on Twitter (2013-7).

Free open access medical education (FOAM) is a community of resources for clinical learning, and is highly used in emergency medicine, particularly among medical students, residents, and fellows. FOAM content is shared across online platforms; however, the majority is shared through Twitter. Many emergency medicine programs have created blogs or are actively using Twitter for didactic topics. Yet, despite increased use of FOAM, no studies to our knowledge have examined trends in popular FOAM topics. This ar...

Extreme Heat Shielding of Clay/Chitosan Nanobrick Wall on Flexible Foam.

Flexible polyurethane foam is widely used in bedding, transportation, and furniture, despite being highly flammable. In an effort to decrease the flammability of the polymer, an environmentally-friendly flame retardant coating was deposited on polyurethane foam (PUF) via layer-by-layer assembly. Treated foam was subjected to three different fire scenarios - 10 s torch test, cone calorimetry, and a 900 s burn-through test - to evaluate the thermal shielding behavior of an eight bilayer chitosan/vermiculite c...

Detection of the efficiency of microwave-oxidation process for meat industry wastewater by dielectric measurement.

Our experimental work focused on the applicability of a quite novel process for wastewater treatment, i.e. a microwave (MW) irradiation-enhanced Fenton-like method. The aim of our research was to detect and evaluate the efficiency of this oxidation process, during the treatment of meat industry wastewater containing a high concentration of organic material. The efficiency was defined by the measurement of the change in COD (chemical oxygen demand, with an initial COD value of 1,568 mg L), and with the deter...

Characterization of the T Cell Response to Polypropylene Mesh in Women with Complications.

Polypropylene mesh is widely used for surgical treatment of pelvic organ prolapse and stress urinary incontinence. While these surgeries demonstrate favorable functional and anatomical outcomes, their use has been limited by complications, the two most common being exposure and pain. Growing evidence suggests T lymphocytes play a critical role in regulating the host response to biomaterials.

Electron donating capacity reduction of dissolved organic matter by solar irradiation reduces the cytotoxicity formation potential during wastewater chlorination.

After treated wastewater is discharged into surface water for unplanned indirect potable reuse, solar irradiation transforms the dissolved organic matter (DOM), which would alter the formation of disinfection byproducts (DBPs) and change the cytotoxicity formation potential (CtFP) during post-chlorination in drinking water treatment plants. This study investigated the effects of solar irradiation on the CtFP and total organic halogen formation potential (TOXFP) of wastewater during post-chlorination. Exposu...
