Molecular Processing of Tau Protein in Progressive Supranuclear Palsy: Neuronal and Glial Degeneration
(IOS Press BV, 2021)Alzheimer's disease (AD) and progressive supranuclear palsy (PSP) are examples of neurodegenerative diseases, characterized by abnormal tau inclusions, that are called tauopathies. AD is characterized by highly insoluble ... -
Monitoring temporal changes in SARS-CoV-2 spike antibody levels and variant-specific risk for infection, Dominican Republic, March 2021–August 2022
(RESEARCH, 2023)To assess changes in SARS-CoV-2 spike binding antibody prevalence in the Dominican Republic and implications for immunologic protection against variants of concern, we prospectively enrolled 2,300 patients with undif ... -
Morphological and fractal properties of brain tumors
(Frontiers in Physiology, 2022-06-27)Tumor interface dynamics is a complex process determined by cell proliferation and invasion to neighboring tissues. Parameters extracted from the tumor interface fluctuations allow for the characterization of the particular ... -
Mortality Rates and Mortality Risk Factors in Older Adults with Dementia from Low- and Middle-Income Countries: The 10/66 Dementia Research Group Population-Based Cohort Study
(Journal of Alzheimer’s Disease 75 (2020) 581–593, 2020-03-09)Background: Dementia is the main cause of disability in older people living in low- and middle-income countries (LMIC). Monitoring mortality rates and mortality risk factors in people with dementia (PwD) may contribute ... -
Mössbauer and X-ray fluorescence study of sediments from Samana Bay, Dominican Republic
(Journal of Radioanalytical and Nuclear Chemistry, 1995-08)The chemical state of iron in sediments collected from Samana Bay has been determined by Mössbauer spectroscopy. The Mössbauer spectra were composed of two paramagnetic doulets, which correspond to high=spin ferric and ... -
Mössbauer study on indigenous ceramics in La Isabela City, Dominican Republic
(Springer Link, 1990)The following study deals with the determination of the firing temperature of some of the ceramics found in La Isabela City, Dominican Republic, first settlement of the Spaniards in the New World. These ceramics were ... -
Multifractal analysis of brain tumor interface in glioblastoma
(PulbMed, 2024)The dynamics of tumor growth is a very complex process, generally accompanied by numerous chromosomal aberrations that determine its genetic and dynamical heterogeneity. Consequently, the tumor interface exhibits a non-regular ... -
Multiple unhealthy behaviors share equivalent profiles of readiness for change in patients with type 2 Diabetes
(International Journal of Environmental Research and Public Health, 2021-03-31)Few studies have considered more than one behavior, despite the tendency towards multiple behaviors, and there are none that have focused on a Latino population. We determined the concurrence of four unhealthy behaviors ... -
