Human immunodeficiency virus (HIV) is a virus that causes acquired immunodeficiency syndrome, a chronic and incurable disease of the human immune system. As the standard of care for the patients with HIV-1, current highly active antiretroviral treatment has been therapeutically effective in most patients; however, it is not curative, and highly active antiretroviral treatment is intolerable because of severe adverse effects. Therefore, nucleic acid-based therapeutics, such as antisense oligonucleotide, ribozyme, messenger RNA, RNA interference (RNAi)-based therapeutics, aptamer, and so on, have been actively developed as alternative or adjuvant agents for those chemical antiviral drugs to surmount those drawbacks. ⋯ The combined use of small interfering RNA (siRNAs) and aptamers could effectively block viral replication and prevent the emergence of resistant variants. The present review offers a brief overview of the use of cell-type-specific aptamer and aptamer-siRNA conjugates' development in our group for the treatment of HIV-1. Their potentials for targeted delivering RNAi therapeutics (eg, siRNA) and suppressing HIV-1 replication in vitro and in humanized animal model will be highlighted here.

Accumulating evidence shows that gradual loss of white matter integrity plays an important role in the development of Alzheimer disease (AD). ⋯ The radiographic manifestation of damaged white matter microstructural integrity in the cholinergic pathway in MCI patients may provide a rational basis for the use of cholinesterase inhibitor drugs in the MCI stage of AD.

Cirrhosis is diagnosed in patients of all ages and is the end result of many different diseases. The aim of this study was to characterize clinical and ethnic features of adult patients who were admitted to the hospital at different (young/old) ages and examine associations between age and ethnicity within these groups. ⋯ The data suggest an association between ethnicity and age of cirrhosis diagnosis, both overall and in patients with certain cirrhosis etiologies. This work raises the possibility of an ethnic and/or genetic basis for cirrhosis.

The medical research enterprise depends on public recognition of its societal value. In light of evidence indicating public mistrust, especially among minorities, inadequate enrollment as well as diversity of research participants, and poor uptake of findings, medical research seems to fall short of sufficient public regard. Community engagement in medical research, with special attention to minority communities, may help to remedy this shortfall by demonstrating respect for the communities in practical ways. ⋯ The 2 potential outgrowths of demonstrating respect specifically through community engagement are (1) the production of research that is more relevant to the community and (2) the mitigation of asymmetry in the researcher-community relationship. We summarized practical resources available to researchers who seek to incorporate community engagement in their research.

The objective of this study was to provide recommendations for provision of training for sponsor and investigators at Academic Health Centers. ⋯ The CTSA IND/IDE Task Force recommendations are as follows: (1) Institutions should assess the scope of Food and Drug Administration-regulated research, perform a needs analysis, and provide resources to implement a suitable training program; (2) The model of training program should be tailored to each institution; (3) The training should specifically address the unique role of sponsor-investigators, and the effectiveness of training should be evaluated regularly by methods that fit the model adopted by the institution; and (4) Institutional leadership should mandate sponsor-investigator training and effectively communicate the necessity and availability of training.
