Current Status of Healthy Aging and Dementia Research: A Symposium Summary

The purpose of the 'First Regional Healthy Aging and Dementia Research Symposium' was to discuss the latest research in healthy aging and dementia research, public health trends related to neurodegenerative diseases of aging, and community-based programs and research studying health, nutrition, and cognition. This symposium was organized by the Garrison Institute on Aging (GIA) of the Texas Tech University Health Sciences Center (TTUHSC), and was held in Lubbock, Texas, October 24-25, 2018. The Symposium joined experts from educational and research institutions across the United States. The two-day Symposium included all GIA staff and researchers. Students, postdoctoral fellows, and faculty members involved in dementia research presented at the Symposium. Healthcare professionals, from geriatricians to social workers working with patients with neurodegenerative diseases, also presented. In addition, experts traveled from across the United States to participate. This event was comprised of multiple sessions, each with several oral presentations, followed by questions and answers, and discussion.

Garrison Institute on Aging-Lubbock Retired and Senior Volunteer Program (RSVP) Provides Services to South Plains, Texas

The Texas Tech University Health Sciences (TTUHSC) Garrison Institute on Aging (GIA) was established to promote healthy aging through cutting edge research on Alzheimer's disease (AD) and other diseases of aging, through innovative educational and community outreach opportunities for students, clinicians, researchers, health care providers, and the public. The GIA sponsors the Lubbock Retired and Senior Volunteer Program (RSVP). According to RSVP Operations Handbook, RSVP is one of the largest volunteer efforts in the nation. Through this program, volunteer skills and talents can be matched to assist with community needs. It is a federally funded program under the guidance of the Corporation for National and Community Service (CNCS) and Senior Corps (SC). Volunteers that participate in RSVP provide service in the following areas: food security, environmental awareness building and education, community need-based volunteer programs, and veteran services.

Garrison Institute on Aging: A New Hope for Elderly Individuals and Patients with Alzheimer's Disease

The Garrison Institute on Aging (GIA) is an established institute within Texas Tech University Health Sciences Center, whose mission is to promote healthy aging through cutting-edge research on Alzheimer's disease (AD) and other diseases of aging through innovative educational opportunities for students, clinicians, researchers, health care professionals, and the public. The GIA has multiple programs, including both research and education on healthy aging and AD, community outreach, caregiving, the Retired Senior Volunteer Program, Healthy Lubbock, the GIA Brain Bank, healthy aging seminars, research seminars, and collaborations and scholarships. The GIA programs connect basic and clinical researchers and health care professionals, and provide a unique environment to help our growing elderly population and patients with AD and their families.

Hybrid reactor based on combined cavitation and ozonation: from concept to practical reality

The present work gives an in depth discussion related to the development of a hybrid advanced oxidation reactor, which can be effectively used for the treatment of various types of water. The reactor is based on the principle of intensifying degradation/disinfection using a combination of hydrodynamic cavitation, acoustic cavitation, ozone injection and electrochemical oxidation/precipitation. Theoretical studies have been presented to highlight the uniform distribution of the cavitational activity and enhanced generation of hydroxyl radicals in the cavitation zone, as well as higher turbulence in the main reactor zone. The combination of these different oxidation technologies have been shown to result in enhanced water treatment ability, which can be attributed to the enhanced generation of hydroxyl radicals, enhanced contact of ozone and contaminants, and the elimination of mass transfer resistances during electrochemical oxidation/precipitation. Compared to the use of individual approaches, the hybrid reactor is expected to intensify the treatment process by 5-20 times, depending on the application in question, which can be confirmed based on the literature illustrations. Also, the use of Ozonix® has been successfully proven while processing recycled fluids at commercial sites on over 750 oil and natural gas wells during hydraulic operations around the United States. The superiority of the hybrid process over conventional chemical treatments in terms of bacteria and scale reduction as well as increased water flowability and better chemical compatibility, which is a key requirement for oil and gas applications, has been established.

Separation of lipase-positive cells from suspensions of pancreas cells in an isokinetic gradient of Ficoll in tissue culture medium

Lipase-positive cells were separated from suspensions of pancreas cells both by velocity sedimentation and by isopycnic sedimentation. Lipase-positive cells were 51.0 +/- 9.6% of the disaggregated pancreas cells in the starting sample suspension. The purest gradient fractions from experiments using velocity sedimentation for cell separation contained a mean of 98.8 +/- 0.6% lipase-positive cells. Cell separation using isopycnic centrifugation was less effective than cell separation using velocity sedimentation and resulted in a mean purity of only 89.8 +/- 6.8% lipase-positive cells. Lipase positivity was assessed using the Gomori technic with the conditions for fixation slightly modified to be suitable for disaggregated cells.
