An air treatment unit (100) arranged for an intake of a first flow (110) of air into a space (120) in communication with the air treatment unit, and arranged for a discharge of a second flow (130) of air from the space. The air treatment unit comprises a heat-exchanging unit (140) arranged for thermal exchange between the second flow of air and the first flow of air, and a catalyst (150) configured to capture at least one impurity of the first flow of air. The catalyst is provided on at least a portion (160) of the heat-exchanging unit arranged to come into contact with the first flow of air during operation of the air treatment unit.

A method is provided for a condition related to the activity of a protease through the administration of a -defensin, analog, or derivative is described. Suitable proteases include metalloproteases and cysteine proteases such as Cathepsin-C. The -defensin, analog, or derivative can be effectively administered parenterally, topically, or orally.

An air-cooling device for a boat includes a plurality of misting modules and a pump. Each misting module comprises a housing that defines an interior space. The housing has a back that is coupled to a sidewall of a boat. A plurality of slots is positioned in the housing and is configured for air to enter the interior space. A plurality of orifices is positioned in a front of the housing. A plurality of fans is coupled to the housing and positioned in the interior space. Each fan is positioned in an associated orifice. A plurality of nozzles is coupled to the front of the housing. The pump is operationally coupled to the nozzles and a source of water. The pump is positioned to pump water through the nozzles to form a mist. The fans are configured to disperse the mist to cool an area proximate to the housing.
