This study reviewed pain and outcome scores of patients undergoing revision surgery with heterotopic ossification (HO) excision following previous hip arthroscopy. The aim was to determine if performing the excision arthroscopically improved clinical outcomes. Data were prospectively collected and retrospectively reviewed in patients who had HO removed arthroscopically between February 2008 and...

In this study, different assays were used to assess the structural and functional integrity of the sperm plasma membrane following freezing-thawing of the whole ejaculates (WEs) and sperm-rich fractions (SRFs) of boar semen. Besides sperm viability assessments (motility and mitochondrial membrane potential using a mitochondrial specific dye, JC-1 with propidium iodide, PI), sperm plasma membran...

Antioxidant properties of ghrelin have been demonstrated in recent studies. In the present study, theeffects of chronic administration of ghrelin on the motility and plasma membrane integrity of rat spermatozoa during incubation at 37ºC were investigated. Thirty 45-day-old male Wistar rats were divided into control and treatment groups. Rats in the treatment group were daily injected subcutaneo...

| Volterra lters (VFs) and higher order statistics (HOS) are important tools for nonlinear analysis, processing, and modeling. Despite their highly desirable properties, the transfer of VFs and HOS to real-world signal processing problems has been hindered by the requirement of very large data records needed to obtain reliable estimates. The identiication of VFs and the estimation of HOS both f...

This case demonstrates a rarely reported bilateral scapulohumeral bony ankylosis. A young woman developed extensive heterotopic ossifications (HOs) in both shoulder joints after being mechanically ventilated for several months at the intensive care unit in a comatose status. She presented with a severe movement restriction of both shoulder joints. Surgical resection of the bony bridges was perf...

The present study was performed to establish and characterize new human osteosarcoma cell lines resistant to pyropheophorbide-α methyl ester‑mediated photodynamic therapy (MPPa-PDT). MPPa-PDT-resistant cells are isolated from the human osteosarcoma MG63 and HOS cell lines and two resistant populations were finally acquired, including MG63/PDT and HOS/PDT. Cell Counting Kit-8 (CCK-8) assay was u...

For a space X belonging to a class including all double suspensions of finite type, we construct for any field k a cochain complex hos(X) such that H∗ ( hos(X) ) ∼= H∗(LXhS1 ; k), the cohomology of the homotopy orbit space of the natural S-action on the free loop space LX. The model hos∗(X) is “small” and thus lends itself relatively easily to explicit computation. Furthermore hos∗(X) fits into...

AIM Patients with a high-output stoma (HOS) (> 2000 ml/day) suffer from dehydration, hypomagnesaemia and under-nutrition. This study aimed to determine the incidence, aetiology and outcome of HOS. METHOD The number of stomas fashioned between 2002 and 2006 was determined. An early HOS was defined as occurring in hospital within 3 weeks of stoma formation and a late HOS was defined as occurrin...

Fresh semen obtained from infertile men occasionally exhibits the total absence of motile sperm (100%asthenozoospermia). Vitality tests may reveal that a proportion of the immotile sperm has functional membranes, which are considered viable. An easy test for the prior determination of sperm viability may assist in sperm selection for the microinjection of oocytes. The main objective of this stu...

Homologue of Slimb (HOS)/b-transducin repeats containing proteins up-regulate nuclear factor kB activity by targeting its inhibitor (IkB) for ubiquitination and subsequent degradation. We investigated whether inhibition of HOS function may modulate apoptosis in human melanoma cells. Forced expression of the dominant negative HOS construct inhibited IkB degradation and led to sensitization of me...
