Friend or Foe: Paradoxical Roles of Autophagy in Gliomagenesis.

Glioblastoma multiforme (GBM) is the most common and aggressive type of primary brain tumor in adults, with a poor median survival of approximately 15 months after diagnosis. Despite several decades of intensive research on its cancer biology, treatment for GBM remains a challenge. Autophagy, a fundamental homeostatic mechanism, is responsible for degrading and recycling damaged or defective cellular components.

Chemical Vapor Deposition of Carbon Nanocoils Three-Dimensionally in Carbon Fiber Cloth for All-Carbon Supercapacitors.

An Au/K bicatalyst-assisted chemical vapor deposition process using CH to grow high-density carbon nanocoils (CNCs) uniformly on the fibers in carbon fiber cloth substrates three-dimensionally was developed. An as-deposited substrate (2.5 × 1.

Melancholy, Acculturation, and Relief: A Brief Essay on the Religion of Ordinarity.

Han is not an idiosyncratic, psychological experience that is peculiar to Koreans, but a multifaceted mode of melancholy experienced by many and various people. What makes this psychological experience particularly familiar to Koreans, however, is that this phenomenon is colored by various, macroscopic factors common in the Korean context, such as sociocultural rigidness, historical instability, political feudality, and economic vulnerability. In this sense, han is an acculturated, multifaceted melancholy.

Fabrication, Polarization of Electrospun Polyvinylidene Fluoride Electret Fibers and Effect on Capturing Nanoscale Solid Aerosols.

Electrospun polyvinylidene fluoride (PVDF) fiber mats with average fiber diameters (≈200 nm, ≈2000 nm) were fabricated by controlled electrospinning conditions. These fiber mats were polarized using a custom-made device to enhance the formation of the electret β-phase ferroelectric property of the fibers by simultaneous uniaxial stretching of the fiber mat and heating the mat to the Curie temperature of the PVDF polymer in a strong electric field of 2.5 kV/cm.

Effective Synthesis of Highly Oxidized Graphene Oxide That Enables Wafer-scale Nanopatterning: Preformed Acidic Oxidizing Medium Approach.

Demand for rapid and massive-scale exfoliation of bulky graphite remains high in graphene commercialization and property manipulation. We report a procedure utilizing "preformed acidic oxidizing medium (PAOM)" as a modified version of the Hummers' method for fast and reliable synthesis of graphene oxide. Pre-mixing of KMnO and concentrated HSO prior to the addition of graphite flakes enables the formation of effectively and efficiently oxidized graphene oxide (EEGO) featured by its high yields and suspension homogeneity.

Comparative dissolution of electrospun AlO nanofibres in artificial human lung fluids.

Sub-micron sized alumina fibres were fabricated by electrospinning and calcination of a polymer template fibre. In the calcination step, different controlled temperature heating cycles were conducted to obtain fibres of different crystalline structures. Their biodurabilities were tested at pH 7.

Microscopy analysis and production rate data for needleless vertical rods electrospinning parameters.

A multiple vertical rod setup for needless electrospinning was used to fabricate submicron polymer fibers. The design with multiple vertical rods is a new concept for increased production of electrospun fibers. Different geometries and operating conditions are possible.

Social mobility and psychiatric disabilities: an assessment of the social causation and social selection hypotheses.

Social mobility is the movement of individuals, families and groups from one social position to another. Researchers indicate that people with psychiatric disabilities tend to come from lower socioeconomic status groups, and that the causal relationship between lower socioeconomic status and mental illness occurs through social mobility process. The purpose of this study was to examine the occupational social mobility process of a sample of self-identified psychiatrically disabled individuals who have been active members of the labor force for most of their adult lives.
