Staphylococcus epidermidis is a leading cause of hospital-associated infections, including those of intravascular catheters, cerebrospinal fluid shunts, and orthopedic implants. Multiple biofilm matrix molecules with heterogeneous characteristics have been identified, including proteinaceous, polysaccharide, and nucleic acid factors. Two of the best-studied components in S. epidermidis include ...

Anatomy Surrounding the spinal cord in the bony vertebral column are three membranes. From the immediate overlay of the cord to the periphery, there are the pia mater, the arachnoid mater, and the dura mater [11]. Between the pia and the arachnoid is the space of interest in spinal anesthesia, the subarachnoid space. In this space are the cerebrospinal fluid (CSF), spinal nerves, a trabecular n...

The primal-dual algorithm of parametric linear programming (e.g. {l]) can be extended in some sence to parametric quadratic programming problems as follows. § 1. Problem of the first type Let us consider the following quadratic programming problem PIA with a parameter A. where C is an n X n positive semi-definite matrix, A is an m X n matrix, p and x are n-vectors, and band d are m-vectors. We ...

Previous studies showed that mice with pristane-induced arthritis (PIA) and those protected from the disease by preimmunization with mycobacterial 65-kDa heat shock protein (hsp65) possess raised immune responses to hsp65. Additionally, T cells from hsp65-protected mice, but not from pristane-injected or normal mice, produced the Th2-associated cytokines IL-4, IL-5, and IL-10 in response to sti...

The outermost layer is the dura mater. The middle layer is the arachnoid mater. The inner layer is the pia mater. The epidural space is the space between the vertebral column and the dura mater. There is only a 'potential' epidural space in the skull. The subdural space is the space between the dura mater and the arachnoid mater. The subarachnoid space is the space between the arachnoid mater a...

We have measured serum immunoreactive trypsin (IRT) and serum pancreatic isoamylase (PIA) activities using commercially available kits in 37 cystic fibrosis (CF) patients and 46 hospital controls of similar age range. Immunoreactive trypsin was more often abnormal than PIA (26/37 v 18/37 abnormal respectively); IRT will be particularly useful as an additional diagnostic test in older children, ...

INTRODUCTION Peripheral intravenous access (PIA) is a necessity in the treatment and monitoring of the majority of hospitalised patients. Patients with an increased body mass index (BMI) more often than normal-weight patients have a difficult PIA. Identifying veins with ultrasonography has proven helpful when facing a difficult intravenous (IV) access. We hypothesise that, with the help of ultr...

Mammalian basic helix-loop-helix proteins of the achaete-scute family are proneural factors that, in addition to the central nervous system, are required for the differentiation of peripheral neurons and sensory cells, derivatives of the neural crest and placodal ectoderm. Here, in identifying the molecular nature of the pia mutation, we investigate the role of the zebrafish achaete-scute homol...
