Low back pain is common and originates in the sacroiliac (SI) joint in 15%-30% of cases. Traditional SI joint disruption/degenerative sacroiliitis treatments include nonoperative care or open SI joint fusion. To evaluate the usefulness of newly developed minimally-invasive technologies, the costs of traditional treatments must be better understood. We assessed the costs of nonoperative care for SI joint disruption to commercial payers in the United States (US).', 'A retrospective study of claim-level medical resource use and associated costs used the MarketScan® Commercial Claims and Encounters as well as Medicare Supplemental Databases of Truven Healthcare. Patients with a primary ICD-9-CM diagnosis code for SI joint disruption (720.2, 724.6, 739.4, 846.9, or 847.3), an initial date of diagnosis from January 1, 2005 to December 31, 2007 (index date), and continuous enrollment for ≥1 year before and 3 years after the index date were included. Claims attributable to SI joint disruption with a primary or secondary ICD-9-CM diagnosis code of 71x.xx, 72x.xx, 73x.xx, or 84x.xx were identified; the 3-year medical resource use-associated reimbursement and outpatient pain medication costs (measured in 2011 US dollars) were tabulated across practice settings. A subgroup analysis was performed among patients with lumbar spinal fusion.', 'The mean 3-year direct, attributable medical costs were $16,196 (standard deviation [SD] $28,592) per privately-insured patient (N=78,533). Among patients with lumbar spinal fusion (N=434), attributable 3-year mean costs were $91,720 (SD $75,502) per patient compared to $15,776 (SD $27,542) per patient among patients without lumbar spinal fusion (N=78,099). Overall, inpatient hospitalizations (19.4%), hospital outpatient visits and procedures (14.0%), and outpatient pain medications (9.6%) accounted for the largest proportion of costs. The estimated 3-year insurance payments attributable to SI joint disruption were $1.6 billion per 100,000 commercial payer beneficiaries.

B-type natriuretic peptide (BNP)-natriuretic peptide receptor A (NPR-A) receptor signalling inhibits cardiac sympathetic neurotransmission, although C-type natriuretic peptide (CNP) is the predominant neuropeptide of the nervous system with expression in the heart and vasculature. We hypothesized that CNP acts similarly to BNP, and that transgenic rats (TGRs) with neuron-specific overexpression of a dominant negative NPR-B receptor would develop heightened sympathetic drive.', 'Mean arterial pressure and heart rate (HR) were significantly (P\u2009<\u20090.05) elevated in freely moving TGRs (n\u2009=\u20099) compared with Sprague Dawley (SD) controls (n\u2009=\u200910). TGR had impaired left ventricular systolic function and spectral analysis of HR variability suggested a shift towards sympathoexcitation. Immunohistochemistry demonstrated co-staining of NPR-B with tyrosine hydroxylase in stellate ganglia neurons. In SD rats, CNP (250\u2009nM, n\u2009=\u20098) significantly reduced the tachycardia during right stellate ganglion stimulation (1-7\u2009Hz) in vitro whereas the response to bath-applied norepinephrine (NE, 1\u2009μM, n\u2009=\u20096) remained intact. CNP (250\u2009nM, n\u2009=\u20098) significantly reduced the release of

An early sign of apoptosis in many cells is the appearance of phosphatidylserine (PS) on the outside of the plasma membrane, whilst the cells still retain the ability to exclude DNA-binding molecules such as propidium iodide and 7-aminoactinomycin D (7-AAD). The protein annexin V binds preferentially to PS and has often been used to monitor the early phase of apoptosis. There have been some conflicting results concerning whether annexin V binds to camptothecin (CAM)-treated HL-60 cells, a commonly used model for apoptosis. We investigated the effects of culturing HL-60 cells for up to 8 h with a range of CAM concentrations.', 'We used flow cytometry to measure cellular light scatter, annexin V-FITC binding, and 7-AAD uptake, and DNA content after fixation and permeabilization. We also used microscopy to examine the morphology of cells (both unsorted and sorted according to their light scatter) after cytocentrifugation.', 'We found that CAM caused the rapid appearance of low light scatter apoptotic bodies. Even among cells with "normal" light scatter, there was widespread DNA cleavage and nuclear fragmentation by 3 h. The percentage of apoptotic bodies peaked at about 4 h and it was only afterward that annexin V binding could be detected to both intact cells and to apoptotic bodies. When they first appeared, the intact annexin V+ cells had S-phase DNA content.
