Vital signs.
9 15 36 Nerve center: I told the neurologist, 'I'm having a stroke. These are my symptoms.' I wasn't all upset about it. Needle and the damage done: In my 25 years of doing substance abuse research here I've never seen anything like this… Age old question: How old is your skeleton? It seems like a simple question. As old as you are, right? Not exactly. In this edition of Vital Signs, we tackle ...
متن کاملThin and open vessel windows for intra-vital fluorescence imaging of murine cochlear blood flow.
Normal microvessel structure and function in the cochlea is essential for maintaining the ionic and metabolic homeostasis required for hearing function. Abnormal cochlear microcirculation has long been considered an etiologic factor in hearing disorders. A better understanding of cochlear blood flow (CoBF) will enable more effective amelioration of hearing disorders that result from aberrant bl...
متن کاملComplete Blood Count and Retinal Vessel Calibers
OBJECTIVE The influence of hematological indices such as complete blood count on microcirculation is poorly understood. Retinal microvasculature can be directly visualized and vessel calibers are associated with a range of ocular and systemic diseases. We examined the association of complete blood count with retinal vessel calibers. METHODS Cross-sectional population-based Blue Mountains Eye ...
متن کاملEffect of cool dialysate on vital signs, comfort and adequacy
Abstract Introduction: Cool dialysate solution is an important factor in maintenance of cardio–vascular stability in hemodialysis patients. Objective: This study aimed to determine the effect of dialysate temperature on vital signs, comfort and adequacy of dialysis in hemodialysis patients. Methods: This study is a clinical trial conducted on 30 hemodialysis patients hospitalized in hemod...
متن کاملVital signs investigation in subjects undergoing MR imaging at 8T.
PURPOSE This study investigates physiologic vital signs in subjects, with and without cerebral pathologies, undergoing ultra-high-field (UHF) 8T MR imaging. METHODS AND SUBJECTS Eighteen normal subjects and 74 subjects with cerebral pathology consented for 8T UHF MR imaging. T2*-weighted gradient-echo and T2-weighted rapid acquisition relaxation excitement sequences were used. Physiologic vit...
