Platelet (PLT) transfusion is undertaken in a variety of clinical settings with thrombocytopenia, with or without bleeding. Since PLTs are most often stored in donor plasma, group-specific PLT transfusions are preferred to out-of-group transfusions. PLTs adsorb ABO antigens over their surface from the plasma. In major ABO-incompatible PLT transfusions, anti-A/B from the patient plasma react with the ABO antigens on transfused PLTs and can potentially cause adverse reactions or PLT refractoriness. Transfusion of PLTs with major ABO incompatibility, though effective in preventing clinical bleeding, is associated with reduced posttransfusion PLT count increments. In minor incompatible PLT transfusion transfused, anti-A/B can cause hemolytic transfusion reaction (HTR) which is not always related to a high titer of anti-A/B in the donor. Although attempts are made to practice ABO identical PLT transfusion, most centers practice out-of-group random donor platelets (RDPs) as well as single-donorplatelets (SDP) transfusion. The limited PLT shelf life does not always permit ABO identical PLT transfusion. At our center, ABO-specific PLT transfusions are practiced where possible, and in case of minor ABO-incompatible transfusions, antibody titers are not done. Here, we report a case of HTR due to out-of-group SDP transfusion, detected in the laboratory after an incompatible red blood cell (RBC) crossmatch.

Controlling Home Appliances remotely is à main part of automation. There is a great deal of inconvenience in controlling each digital home appliance with its own separate remote. In this paper we present an advanced universal remote which can control and regulate lights, fans and also any IR controlled Home appliance like TV, home theater, air conditioner etc. This paper gives the design on how to build this remote and how we can turn our smart phone into a true universal remote which will be both versatile and have capability to easily learn new devices and new IR protocols.

Pulse Electromagnetic therapy is usually referred by doctors for clinical management of quick bone healing, repair of damaged tissues and as a quick remedy for pain. Various PEMT equipment are already available in market, but none of them are available as low cost consumer electronic device. Authors tried to develop a low cost version of micro controller controlled PEMT device. The design and construction method of this PEMT device has been thoroughly discussed in this paper. The prototype constructed not only met the low cost criteria but also was equally effective at pain management and bone healing.
