Intracellular localization of organelles may depend in part on specific cytoplasmic linker proteins (CLIPs) that link membranous organelles to microtubules. Here, we characterize rat cDNAs encoding a novel, brain-specific CLIP of 115 kDa. This protein contains two N-terminal microtubule-binding domains and a long coiled-coil region; it binds to microtubules and is homologous to CLIP-170, a prot...
Molecular clips based on propanediurea: exceptionally high binding affinities for resorcinol guests.
A series of new receptor molecules derived from 2,4,6,8-tetraazabicyclo[3.3.1]nonane-3,7-dione (propanediurea) is described. These molecules possess a cavity which is defined by two nearly parallel aromatic side walls positioned on top of a bis-urea framework. The resulting "U-shaped" clip molecules are ideal hosts for the complexation of flat aromatic guest molecules. The affinity of these new...
We developed a paperclip-shaped motion-actuating system, named “Move-it”. With this system, users can add motions to sticky notes just by clipping it. This system is constructed by using clip-shaped devices that have sensors and actuators. The recognition system uses photo interrupter module as sensor. Each clip device can recognize which note it has been attached to by calculating how much inf...
Tencent Text-Video Retrieval: Hierarchical Cross-Modal Interactions with Multi-Level Representations
Text-Video Retrieval plays an important role in multi-modal understanding and has attracted increasing attention recent years. Most existing methods focus on constructing contrastive pairs between whole videos complete caption sentences, while overlooking fine-grained cross-modal relationships, e.g., clip-phrase or frame-word. In this paper, we propose a novel method, named Hierarchical Cross-M...
The aim of the present study was to evaluate the ability of seven staging systems to predict 3- and 6-month and cumulative survival rates of patients with advanced hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC). Data were collected from 220 patients with HBV-associated HCC who did not receive any standard anticancer treatment. Participants were patients at The Third Affiliate...
BACKGROUND We report two procedures using a stent-assisted microsurgical clip placement to treat complex intracranial aneurysms originating from supraclinoid segment of the internal carotid artery. CASE DESCRIPTIONS In both procedures, primary clip placement was considered technically difficult due to either complex morphology or inferior protrusion of aneurysm fundus within the interclinoid ...
Rupture of an intracranial aneurysm is a serious neuro-vascular event requiring immediate management to avoid devastating neurological sequelae. Despite the rapid evolution of endovascular techniques, clipping is still a necessary tool in aneurysms with non-optimal dometo-neck ratio and in younger patients. Occasionally, optimal positioning of an aneurysm clip with optimal obliteration of the a...
OBJECTIVE To assess the failure rate of Filshie clip sterilisations in Victoria, Australia. DESIGN Retrospective study between 1994 and 1998. SETTING All specialist gynaecologists practising in the state of Victoria, Australia. INTERVENTIONS Questionnaires (up to three) followed by telephone calls if necessary. MAIN OUTCOME MEASURES A response rate of 276/277 (99.6%) was obtained. All p...
