Abstract: A first communication device that is configured to bidirectionally exchange data with a second communication device comprises circuitry that is configured to initiate a bidirectional transmit opportunity (TXOP) by transmitting, to the second communication device, a TXOP indicator indicating that a wideband TXOP is split into two channels and indicating that a first channel is primarily to be used for transmission of data from the first communication device to the second communication device and a second channel is primarily to be used for transmission of data from the second communication device to the first communication device. Further, the first communication device transmits data to the second communication device on the first channel and listen for the reception of data from the second communication device on the second channel.

Abstract: Provided herein are methods and compositions to augment the efficacy and reduce toxicity of non-engrafting, CD8-depeleted allogeneic donor lymphocyte infusions. The compositions comprise isolated leukocytes obtained from a donor subject that (i) are mismatched to a recipient subject for at least one human leukocyte antigen (HLA) Class II allele mismatch in the donor versus recipient (graft-versus-host) direction relative to the recipient subject or (ii) is mismatched to a recipient subject for at least one human leukocyte antigen (HLA) Class II allele mismatch in the donor versus recipient (graft-versus-host) direction relative to the recipient subject, is matched to the recipient for at least one human leukocyte antigen (HLA) Class II allele, and has CD4+ T cell immunity against an antigen present in a recipient subject.

Abstract: Methods for preventing or ameliorating decreased pulmonary function and pulmonary inflammation in a subject infected with SARS coronavirus such as SARS-CoV-2 by administration of certain tyrosine kinase inhibitors such as ibrutinib to the subject are provided.
