Abstract: A room humidifying apparatus is provided which operates with minimum cost and without any electrical power. The humidifier is located so as to make use of a stream of air coming from a register. The humidifier has a casing carrying a main water tank, a water pan and an evaporative filter element which are located in the casing. The tank drips water onto the filter element, which has a lower portion located in the water pan to collect any excess water dripping down the filter element and also to moisten it with capillary effect. Heated air from the register becomes humidified on passing through the filter element. The water tank can be filled manually from the top or be detachable and filled through a bottom refill opening. Alternatively, the water tank can be connected to a water source with a valve to regulate the flow of water into the water tank. The water tank may be balanced so as to displace, for example tilt, from a first position when it contains water to a second position when it is empty.

Abstract: The present invention relates to Fc region-containing polypeptides that exhibit improved effector function due to alterations of the extent of fucosylation, and to methods of using such polypeptides for treating or preventing cancer and other diseases. The Fc region-containing polypeptides of the present invention are preferably immunoglobulins (e.g., antibodies), in which the Fc region comprises at least one amino acid substitution relative to the corresponding amino acid sequence of a wild type Fc region, and which is sufficient to attenuate post-translational fucosylation and mediate improved binding to an activating Fc receptor and reduced binding to an inhibitory Fc receptor. The methods of the invention are particularly useful in preventing, treating, or ameliorating one or more symptoms associated with a disease, disorder, or infection where either an enhanced efficacy of effector cell function mediated by Fc?R is desired (e.g., cancer, infectious disease) or an inhibited effector cell response mediated by Fc?R is desired (e.g., inflammation, autoimmunde disease).
