Clip migration into the common bile duct (CBD) is a rare but well-established phenomenon of laparoscopic biliary surgery. The mechanism and exact incidence of clip migration are both poorly understood. Clip migration into the common bile duct can cause recurrent cholangitis and serve as a nidus for stone formation. We present a case, a 54-year-old woman, of clip-induced cholangitis resulting fr...

The purpose of this study was to histologically and mechanically investigate the in vivo bone-bonding ability of anodically oxidized titanium (AO Ti) with an anatase crystal layer on its surface. AO Ti plates, anodically oxidized at 155 V in 1 M H2SO4, were implanted into the proximal metaphyses of mature rabbit tibiae for 4, 8, 16, and 24 weeks and investigated by light microscopy, scanning el...

In spinal cord injuries, direct trauma by edges of sublaxated or dislocated vertebrae and indirect ischemia as a result of vascular injury necrotize the neural tissue. After spinal cord injury, tissue loss appears as micro- or macrocavitation. Accumulations of non-neuronal cells substitute spared tissue and halts axon regrowth. Lack of supporting cells (secreting trophic factors and matrix) agg...

An implant elicits a biological response in the surrounding tissue which determines the acceptance and long-term function of the implant. Dental implants have become one of the main therapy methods in clinic after teeth lose. A successful implant is in contact with bone and soft tissue represent by fibroblasts. In our study we focused on the interaction between six different chemically and phys...

Linkage of microtubules to special cortical regions is essential for cell polarization. CLIP-170 binds to the growing ends of microtubules and plays pivotal roles in orientation. We have found that IQGAP1, an effector of Rac1 and Cdc42, interacts with CLIP-170. In Vero fibroblasts, IQGAP1 localizes at the polarized leading edge. Expression of carboxy-terminal fragment of IQGAP1, which includes ...

INTRODUCTION Percutaneous implants, such as bone conduction hearing implants, suffer from complications that include inflammation of the surrounding skin. A sealed skin-abutment interface can prevent the ingress of bacteria, which should reduce the occurrence of peri-abutment dermatitis. It was hypothesized that a hydroxyapatite (HA)-coated abutment in conjunction with soft tissue preservation ...

PURPOSE Several parameters have been described for determining the success or failure of dental implants. The surface properties of transgingival implant components have had a great impact on the long-term success of dental implants. The purpose of this study was to compare the tendency of two periodontal pathogens to adhere to and colonize zirconia abutments and titanium alloys both in hard su...

The possible occurrence of phosphorylation of proadrenocorticotropin(ACTH)/endorphin-derived peptides in the rat was examined by incubating dissociated anterior and intermediate pituitary cells with a %amino acid plus 32Pi. In both lobes of the pituitary newly synthesized pro-ACTH/endorphin was labeled with 32P. In the intermediate pituitary, corticotropin-like intermediate lobe peptide (CLIP) ...

An 86-year-old man with atrial fibrillation on anticoagulation was admitted to another hospital for an upper gastrointestinal bleed after accidental ingestion of a plastic bread clip. He required 11 units of packed red blood cells for resuscitation. Esophagogastroduodenoscopy demonstrated the clip firmly wedged onto a duodenal fold (Figure 1) with bleeding from adjacent mucosa. Attempts to remo...

CLiP (Code from Literate Program) is a tool which allows writing literate programs in virtually any programming language (Pascal, Fortran, C, C++, Assembler languages, etc) and in combination with almost any formatter (Runoff, Troff, TeX, LaTeX, etc.) or word-processor (Winword, Lotus Manuscript, Ami Pro, Word Perfect, Wordstar, etc). This posting explains the CLiP philosophy and compares it to...
