Dysregulation of astrocytic Aquaporin-1 in the brains of oldest-old rhesus macaques: the NIA caloric restriction study.

Aquaporin-1 (AQP1) is a highly conserved water-channel protein, found to be expressed by astrocytes in adult humans and non-human primates (NHPs). Upregulation of cortical AQP1 expression occurs with cancer, injury, and neurodegenerative disease, but minimal information is available about the effects of normative aging on AQP1 expression. This study leverages tissues from the oldest-old rhesus macaques, some greater than 40 years of age, from the National Institute on Aging longitudinal study of caloric restriction (CR).

Surgical Treatment of Single Level Cervical Radiculopathy: A Comparison of Anterior Cervical Decompression and Fusion (ACDF) Versus Cervical Disk Arthroplasty (CDA) Versus Posterior Cervical Foraminotomy (PCF).

Study Design: This was a retrospective cohort study.

Objective: The objective of this study is to retrospectively compare the clinical outcomes, complication rates, and reoperation rates among the 4 treatments in patients with cervical radiculopathy.

Summary Of Background Data: Surgical options for cervical radiculopathy include anterior cervical discectomy and fusion (ACDF), open posterior cervical foraminotomy (O-PCF), minimally invasive posterior cervical foraminotomy (MI-PCF), and cervical disk arthroplasty (CDA).

Post-Operative Spinal Epidural Hematoma: Are We Discontinuing Aspirin Early Enough?

Study Design: Retrospective cohort study.

Objectives: (1) To compare the risk of Spinal Epidural Hematoma (SEH) associated with specific pre-operative and post-operative anticoagulation (AC) and antiplatelet medications (APM). (2) To define the incidence of SEH and identify risk factors for SEH in our population.

Neuraminidase-specific antibody responses are generated in naive and vaccinated newborn nonhuman primates following virus infection.

Individuals younger than 6 months of age are at significant risk from influenza virus infection; however, there is currently no vaccine approved for this age group. Influenza virus neuraminidase (NA) has emerged as a potential additional target for vaccine strategies. In this study, we sought to understand the ability of newborns to mount an antibody response to NA.

Oral curcumin supplementation improves fine motor function in the middle-aged rhesus monkey.

Aged individuals experience decreased fine motor function of the hand and digits, which could result, in part, from the chronic, systemic state of inflammation that occurs with aging. Recent research for treating age-related inflammation has focused on the effects of nutraceuticals that have anti-inflammatory properties. One particular dietary polyphenol, curcumin, the principal curcuminoid of the spice turmeric, has been shown to have significant anti-inflammatory effects and there is mounting evidence that curcumin may serve to reduce systemic inflammation.
