Abstract: A mask (100), such as a filtration mask, with multiple strap configurations is provided. For example, such mask might be worn in either a head strap (240) or an ear strap (110) configuration. The mask comprises two ear straps each with a connector support element (130) allowing removable attachment of a separate head strap.

Abstract: The present application discloses a wire rod for gas shielded welding wire, comprising the following chemical elements in mass percentage: C?0.03%, Mn: 0.20-0.70%, Si: 0.20-0.60%, Ni: 1.6-2.7%, Cr: 1.60-2.20%, Cu: 0.15-0.35%, Ti: 0.01-0.07% and the balance being Fe and inevitable impurities. The present application further discloses a gas shielded welding wire which is made of the above wire rod for gas shielded welding wire. The comprehensive mechanical properties and corrosion resistance of the deposited metal, after the gas shielded welding wire with high weather resistance and low strength is welded, are comparable to those of S350EW (i.e., the welding base material).

Abstract: The present disclosure provides methods and compositions for treating cancer (e.g., lung cancer) in a subject by increasing the expression of PDZ-LIM domain containing protein 2 (PDLIM2) in the subject, or a functional fragment thereof. The present disclosure further provides methods of using PDLIM2 as a marker for determining and monitoring a subject's responsiveness to an anti-cancer treatment, providing a prognosis about a cancer in a subject, and selecting an effective anti-cancer treatment for a subject. The present disclosure also provides in vitro methods of screening anti-cancer agents by assessing whether the expression of PDLIM2 is restored by an anti-cancer agent in a cancer cell.

Abstract: Provided is a superhigh strength gas shielded welding wire containing V, the mass percentage contents of the chemical elements thereof being: 0.08-0.12% of C, 0.65-0.80% of Si, 1.80-1.95% of Mn, 0<Cu?0.25%, 0.20-0.40% of Cr, 0.2-0.6% of Mo, 1.30-1.80% of Ni, 0.08-0.20% of Ti, 0.01-0.05% of V, 0.0070-0.0130% of N, and the balance of Fe and other inevitable impurities. Also provided is a method for manufacturing the welding wire. A weld metal obtained after welding with said welding wire has a higher strength and toughness, and also has a good crack resistance, weldability and plasticity.
