BACKGROUND AND PURPOSE Evidence suggests that activated microglia are detrimental to the survival of new hippocampal neurons, whereas blocking inflammation has been shown to restore hippocampal neurogenesis after cranial irradiation and seizure. The aim of this current study is to determine the effect of minocycline on neurogenesis and functional recovery after cerebral focal ischemia. METHOD...

INTRODUCTION Minocycline and doxycycline are safe and moderately effective disease-modifying anti-rheumatic drugs (DMARDs) in the treatment of early, DMARD-naïve rheumatoid arthritis (RA), although little is known about their use outside clinical trials. We characterize the use of minocycline and doxycycline in community-dwelling RA patients by examining associated prescribing patterns, patient...

Among Acinetobacter species, A. baumannii and other closely related species are commonly implicated in nosocomial infections. These organisms are usually multidrug resistant (MDR), and therapeutic options to treat A. baumannii infections are very limited. Clinicians have been resorting to older antimicrobial agents to treat infections caused by MDR A. baumannii, and some of these agents have do...

Background. Patients on chronic minocycline suppression for orthopedic infections at a single institution were studied for development of minocycline-induced cutaneous hyperpigmentation and analysis of risk factors. Methods. This is a retrospective cohort study of Mayo Clinic patients with hardware or non-hardware associated chronic orthopedic infections treated with long termminocycline suppre...

Objective Delayed cerebral ischemia (DCI) is an independent risk factor for poor outcome after aneurysmal subarachnoid hemorrhage (SAH) and is multifactorial in etiology. While prior studies have suggested a role for matrix metalloproteinase-9 (MMP-9) in early brain injury after SAH, its contribution to the pathophysiology of DCI is unclear. Methods In the first experiment, wild-type (WT) and...

The minimum inhibitory concentrations of penicillin and minocycline were measured on 300 consecutive isolates of N. gonorrhoeae from patients attending the Nottingham treatment centre. 210 (70 per cent.) of these were fully sensitive to penicillin (MIC less than 0-1 mug./ml) and 89 per cent. were fully sensitive to minocycline (MIC less than 0-5 mug./ml.). Of the nine strains resistant to penic...

Parkinson's disease is a chronic neurodegenerative disorder characterized by the loss of dopamine neurons in the substantia nigra, decreased striatal dopamine levels, and consequent extrapyramidal motor dysfunction. We now report that minocycline, a semisynthetic tetracycline, recently shown to have neuroprotective effects in animal models of stroke/ischemic injury and Huntington's disease, pre...

Ischemic stroke is the most common life-threatening neurological disease and has limited therapeutic options. One component of ischemic neuronal death is inflammation. Here we show that doxycycline and minocycline, which are broad-spectrum antibiotics and have antiinflammatory effects independent of their antimicrobial activity, protect hippocampal neurons against global ischemia in gerbils. Mi...

Acute spinal cord injury (SCI) produces tissue damage that continues to evolve days and weeks after the initial insult, with corresponding functional impairments. Reducing the extent of progressive tissue loss ('neuroprotection') following SCI should result in a better recovery from SCI, but treatment options have thus far been limited. In this study, we have tested the efficacy of minocycline ...

PURPOSE To reveal the effects of minocycline, an anti-inflammatory and neuroprotective agent, on the viability and physiological properties of retinal pigment epithelial (RPE) cells and to compare the effects with those of triamcinolone acetonide. METHODS The proliferation of human RPE cells in vitro was investigated with a bromodeoxyuridine immunoassay; chemotaxis was examined with a Boyden ...
