drinking water quality can be deteriorated by microbial and toxic chemicals during transport, storage and handling before using by the consumer. this study was conducted to evaluate the microbial and physicochemical quality of drinking water from bottled water coolers.a total of 64 water samples, over a 5-month period in 2012-2013, were collected from free standing bottled water coolers and wat...

Although they have potential environmental pollution issues, soft contact lenses are value-added biodevices for medical use. Thus, it is important to reconsider starting materials and production methods achieve sustainable development. In this study, hydrogels composed of hydroxypropyl cellulose (HPC) as an environmentally friendly material were produced by radiation investigated use in disposa...

OBJECTIVES/HYPOTHESIS Hemangiopericytomas (HPC) are tumors that arise from pericytes. Hemangiopericytomas of the head and neck are rare and occur both extracranially and intracranially. This study analyzes the demographic, clinicopathologic, treatment modalities, and survival characteristics of extracranial head and neck hemangiopericytomas (HN-HPC) and compares them to HPCs at other body sites...

Hemangiopericytoma (HPC) is a rare vascular tumor that originates from the pericytes of blood vessels. HPC has a propensity for metastasis and is frequently aggressive. HPC can grow rapidly and usually occurs in the base of the skull, falx, tentorium, or nearby sinus, but occurs in the spinal canal less frequently. Peripheral nerve tissue can be compressed by HPC, causing corresponding signs an...

Employers seek recruits who can apply the knowledge, skill, and culture they acquire in college to solve problems as soon enter workforce.

Achieving a prolonged neuroprotective state following transient ischemic attacks (TIAs) is likely to effectively reduce the brain damage and neurological dysfunction associated with recurrent stroke. HPC is a phenomenon in which advanced exposure to mild hypoxia reduces the stroke volume produced by a subsequent TIA. However, this neuroprotection is not long-lasting, with the effects reaching a...

Protein C deficiency results in a thrombotic disorder that might be treated by expressing a normal human protein C (hPC) gene in patients. An amphotropic retroviral vector with a liver-specific promoter and the hPC cDNA was delivered to rat hepatocytes in vivo during liver regeneration. Expression of hPC varied from 55 to 203 ng/ml (1.3-5.0% of normal) for 2 wk after transduction. Expression in...

A major adaptive pathway for hypoxia is hypoxic preconditioning (HPC), a form of endogenous protection that renders cells tolerant to severe challenges of hypoxia. We sought to define the antiinflammatory properties of HPC. cDNA microarray analysis of lung tissue from mice subjected to hypoxia or HPC identified a cluster of NF-kappaB-regulated genes whose expression is attenuated by HPC. Studie...

A monoclonal antibody (mAb), HPC-1, labels the plasma membrane of the amacrine cell soma and inner plexiform layer in rat retina and other central neurons. HPC-1 antigen recognizes several proteins of about 35 kDa. In this study, an HPC-1 positive cDNA, HPC-113, was isolated from a lambda gt11 cDNA library of the rat hippocampus. HPC-113 had the 894-base pair nucleotide sequence in an open read...

Lesions and temporary inactivation of the hippocampus (HPC) in rodents occasionally lead to discrepant amnesic effects. We directly compared and contrasted the retrograde amnesic effects that small HPC lesions (~50% damage), large HPC lesions (~80% damage), and combined dorsal and ventral HPC inactivation using the sodium channel blocker tetrodotoxin (TTX) had on contextual fear conditioning. C...
