A new principle for rapid immunoassay of proteins based on in situ precipitate-enhanced ellipsometry. (1/770)
A new technique is presented that allows measurement of protein concentrations in the picomolar range with an assay time of only 10-20 min. The method is an enzyme-linked immunosorbent assay (ELISA), but uses in-situ ellipsometric measurement of a precipitating enzyme product instead of the usual colorimetric detection of accumulating enzyme product in solution. Quantitative validation was obtained by use of annexin V, a protein with high binding affinity for phosphatidylserine-containing phospholipid membranes, resulting in a transport-limited adsorption rate. This property was exploited to obtain a range of low surface concentrations of annexin V by timed exposures of phospholipid bilayers to known concentrations of annexin V. Using polyvinylchloride (PVC)-coated and silanized silicon slides, various versions of this technique were used for the rapid assay of fatty acid-binding protein (FABP), a recently introduced early marker for acute myocardial infarction with a normal plasma concentration below 1 nmol/l, interleukin 6 (IL-6), a cytokine with normal plasma concentrations below 1 pmol/l, and again, annexin V. A possible future application of the method in the development of a one-step ELISA is discussed. (+info)Crystalline silica exposure, radiological silicosis, and lung cancer mortality in diatomaceous earth industry workers. (2/770)
BACKGROUND: The role of silicosis as either a necessary or incidental condition in silica associated lung cancer remains unresolved. To address this issue a cohort analysis of dose-response relations for crystalline silica and lung cancer mortality was conducted among diatomaceous earth workers classified according to the presence or absence of radiological silicosis. METHODS: Radiological silicosis was determined by median 1980 International Labour Organisation system readings of a panel of three "B" readers for 1809 of 2342 white male workers in a diatomaceous earth facility in California. Standardised mortality ratios (SMR) for lung cancer, based on United States rates for 1942-94, were calculated separately for workers with and without radiological silicosis according to cumulative exposures to respirable crystalline silica (milligrams per cubic meter x years; mg/m3-years) lagged 15 years. RESULTS: Eighty one cases of silicosis were identified, including 77 with small opacities of > or = 1/0 and four with large opacities. A slightly larger excess of lung cancer was found among the subjects with silicosis (SMR 1.57, 95% confidence interval (CI) 0.43 to 4.03) than in workers without silicosis (SMR 1.19, 95% CI 0.87 to 1.57). An association between silica exposure and lung cancer risk was detected among those without silicosis; a statistically significant (p = 0.02) increasing trend of lung cancer risk was seen with cumulative exposure, with SMR reaching 2.40 (95% CI 1.24 to 4.20) at the highest exposure level (> or = 5.0 mg/m3-years). A similar statistically significant (p = 0.02) dose-response gradient was observed among non-silicotic subjects when follow up was truncated at 15 years after the final negative radiograph (SMR 2.96, 95% CI 1.19 to 6.08 at > or = 5.0 mg/m3-years), indicating that the association among non-silicotic subjects was unlikely to be accounted for by undetected radiological silicosis. CONCLUSIONS: The dose-response relation observed between cumulative exposure to respirable crystalline silica and lung cancer mortality among workers without radiological silicosis suggests that silicosis is not a necessary co-condition for silica related lung carcinogenesis. However, the relatively small number of silicosis cases in the cohort and the absence of radiographic data after employment limit interpretations. (+info)Chip-based genotyping by mass spectrometry. (3/770)
Silicon chips with immobilized target DNAs were used for accurate genotyping by mass spectrometry. Genomic DNAs were amplified with PCR, and the amplified products were covalently attached to chip wells via N-succinimidyl (4-iodoacetyl)aminobenzoate (SIAB) chemistry. Primer annealing, extension, and termination were performed on a 1-microl scale directly in the chip wells in parallel. Diagnostic products thus generated were detected in situ by using matrix-assisted laser desorption ionization mass spectrometry. This miniaturized method has the potential for accurate, high-throughput, low-cost identification of genetic variations. (+info)Thin film biosensor for rapid visual detection of nucleic acid targets. (4/770)
BACKGROUND: We have developed a silicon-based biosensor that generates a visual signal in response to nucleic acid targets. METHODS: In this system, capture oligonucleotide probes are immobilized on the surface of the biosensor. Interaction of the capture probes with a complementary target and a biotinylated detector oligonucleotide allows initiation of formation of an organic thin film on the biosensor. Thin film formation is completed by enzymatic activity of peroxidase conjugated to an anti-biotin antibody. Peroxidase catalyzes deposition of an insoluble product onto the silicon surface, generating a uniform thin film. The increased thickness on the surface alters the perceived color of the biosensor through changes in the interference patterns of reflected light from the surface, causing a color change from gold to purple. RESULTS: The biosensor results may be evaluated by direct visual inspection or quantified by ellipsometry. Results are obtained in 25 min with a detection limit of 5 pmol/L (150 amol/sample). Selectivity of the biosensor is demonstrated by discrimination of single nucleotide mismatches. Multitarget arrays are also analyzed with the thin film biosensor, and the system is capable of detecting targets from human serum and urine. CONCLUSIONS: The biosensor surface is inexpensive to produce, and the assay format is simple and rapid. The thin film biosensor is adaptable to a wide variety of nucleic acid detection applications, including rapid diagnostic testing for infectious disease panels, antibiotic resistance panels, or allelic discrimination of specific genetic markers. (+info)Stable five- and six-coordinated silicate anions in aqueous solution. (5/770)
Addition of aliphatic polyols to aqueous silicate solutions is shown to yield high concentrations of stable polyolate complexes containing five- or six-coordinated silicon. Coordinating polyols require at least four hydroxy groups, two of which must be in threo configuration, and coordinate to silicon via hydroxy oxygens at chain positions on either side of the threo pair. The remarkable ease by which these simple sugar-like molecules react to form hypervalent silicon complexes in aqueous solution supports a long-standing supposition that such species play a significant role in the biological uptake and transport of silicon and in mineral diagenesis. (+info)Patterned deposition of cells and proteins onto surfaces by using three-dimensional microfluidic systems. (6/770)
Three-dimensional microfluidic systems were fabricated and used to pattern proteins and mammalian cells on a planar substrate. The three-dimensional topology of the microfluidic network in the stamp makes this technique a versatile one with which to pattern multiple types of proteins and cells in complex, discontinuous structures on a surface. The channel structure, formed by the stamp when it is in contact with the surface of the substrate, limits migration and growth of cells in the channels. With the channel structure in contact with the surface, the cells stop dividing once they form a confluent layer. Removal of the stamp permits the cells to spread and divide. (+info)In situ self hardening bioactive composite for bone and dental surgery. (7/770)
A new biomaterial is presented which consists of a cellulose derivative--silanised hydroxyethylcellulose (HEC-SIL) and biphasic calcium phosphate (BCP). Rheological properties of the polymer itself and its mixture with BCP are pH-dependent. At pH 10-12 HEC-SIL is liquid and undergoes quick gellation at pH < 9. Similarly, the paste of HEC-SIL and BCP is fluid and injectable at higher pH and solidifies in biological solutions. The rate of this solidification can be easily controlled by the degree of substitution of hydroxyethylcellulose with silicoalkoxy groups. (+info)Oligomeric but not monomeric silica prevents aluminum absorption in humans. (8/770)
BACKGROUND: Soluble silica, a ubiquitous component of the diet, may be the natural ligand for dietary aluminum and may prevent its accumulation and toxicity in animals. However, previous studies on the inhibition of aluminum absorption and toxicity by soluble silica have produced conflicting results. We recently identified a soluble silica polymer, oligomeric silica, that has a much higher affinity for aluminum than does monomeric silica and that may be involved in the sequestration of aluminum. OBJECTIVE: By using (26)Al as a tracer, we investigated the effects of oligomeric and monomeric silica on the bioavailability of aluminum (study 1) and compared the availability of silicon from oligomeric and monomeric silica in the human gastrointestinal tract (study 2). DESIGN: In study 1, three healthy volunteers each ingested aluminum alone (control), aluminum with oligomeric silica (17 mg), and aluminum with monomeric silica (17 mg). In study 2, five healthy volunteers ingested both the oligomeric and monomeric forms of silica (34 mg). Serum and urine samples were analyzed for aluminum and silicon. RESULTS: Oligomeric silica reduced the availability of aluminum by 67% (P = 0.01) compared with the control, whereas monomeric silica had no effect (P = 0.40). Monomeric silica was readily taken up from the gastrointestinal tract and then excreted in urine (53%), whereas oligomeric silica was not detectably absorbed or excreted. CONCLUSIONS: The oligomeric, high-aluminum-affinity form of soluble silica reduces aluminum availability from the human gastrointestinal tract. Its potential role in the amelioration of aluminum toxicity in other biological systems requires attention. (+info)I'm sorry for any confusion, but "Silicon" does not have a specific medical definition. Silicon is a chemical element with the symbol Si and atomic number 14. It is a metalloid, which means it has properties of both metals and nonmetals. In the human body, silicon is not considered an essential nutrient, although it is found in trace amounts in various tissues. Some research suggests that silicon might play a role in collagen synthesis and bone health, but more studies are needed to confirm these findings and establish recommended intake levels.
Silicon compounds refer to chemical substances that contain the element silicon (Si) combined with other elements. Silicon is a Group 14 semimetal in the periodic table, and it often forms compounds through covalent bonding. The most common silicon compound is silicon dioxide (SiO2), also known as silica, which is found in nature as quartz, sand, and other minerals.
Silicon can form compounds with many other elements, including hydrogen, oxygen, halogens, sulfur, nitrogen, and carbon. For example:
* Silanes (SiHn) are a series of silicon-hydrogen compounds where n ranges from 1 to 6.
* Silicones are synthetic polymers made up of alternating silicon and oxygen atoms with organic groups attached to the silicon atoms.
* Silicates are a class of minerals that contain silicon, oxygen, and one or more metal cations. They have a wide range of structures and uses, including as building materials, ceramics, and glass.
* Siloxanes are a group of compounds containing alternating silicon-oxygen bonds with organic groups attached to the silicon atoms.
Silicon compounds have various applications in industry, medicine, and daily life. For instance, silicones are used in medical devices such as breast implants, contact lenses, and catheters due to their biocompatibility and flexibility. Silicates are found in pharmaceuticals, cosmetics, and food additives. Silicon-based materials are also used in dental restorations, bone cement, and drug delivery systems.
Carbon inorganic compounds are chemical substances that contain carbon combined with one or more elements other than hydrogen. These compounds include oxides of carbon such as carbon monoxide (CO) and carbon dioxide (CO2), metal carbides like calcium carbide (CaC2) and silicon carbide (SiC), and carbonates like calcium carbonate (CaCO3) and sodium carbonate (Na2CO3).
Unlike organic compounds, which are based on carbon-hydrogen bonds, inorganic carbon compounds do not contain hydrocarbon structures. Instead, they feature carbon bonded to elements such as nitrogen, oxygen, sulfur, or halogens. Inorganic carbon compounds have diverse physical and chemical properties and play important roles in various industrial applications, as well as in biological systems.
Silicon dioxide is not a medical term, but a chemical compound with the formula SiO2. It's commonly known as quartz or sand and is not something that would typically have a medical definition. However, in some cases, silicon dioxide can be used in pharmaceutical preparations as an excipient (an inactive substance that serves as a vehicle or medium for a drug) or as a food additive, often as an anti-caking agent.
In these contexts, it's important to note that silicon dioxide is considered generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA). However, exposure to very high levels of respirable silica dust, such as in certain industrial settings, can increase the risk of lung disease, including silicosis.
I'm sorry for any confusion, but "nanowires" is not a medical term. It is a term used in the field of materials science and nanotechnology. Nanowires are one-dimensional structures with a diameter of 1-100 nanometers (nm) and an aspect ratio (length/diameter) greater than 1000. They have unique electrical, mechanical, and optical properties that make them useful in various applications such as electronics, sensors, energy storage, and biomedical devices.
I'm sorry for any confusion, but "semiconductors" is a term from the field of materials science and electronics rather than medicine. Semiconductors are materials, often silicon-based, that have properties between conductors and insulators. They are used in various electronic devices due to their unique property of controlling the flow of electrical current. If you have any medical questions, I'd be happy to help with those instead!
Organosilicon compounds are a class of chemical compounds that contain at least one organic group (a group of atoms composed mainly of carbon and hydrogen) bonded to a silicon atom. The organic group can be an alkyl group, aryl group, or any other group that is derived from a hydrocarbon.
The term "organosilicon" is used to describe the covalent bond between carbon and silicon atoms, which is a type of bond known as a "sigma bond." This bond is formed by the overlap of atomic orbitals between the carbon and silicon atoms. The resulting organosilicon compound can have a wide range of physical and chemical properties, depending on the nature of the organic group and the number of such groups attached to the silicon atom.
Organosilicon compounds are widely used in various industries, including electronics, coatings, adhesives, and pharmaceuticals. They are also used as intermediates in the synthesis of other chemical compounds. Some common examples of organosilicon compounds include silicones, which are polymers that contain repeating units of siloxane (Si-O-Si) bonds, and organofunctional silanes, which are used as coupling agents to improve the adhesion of materials to surfaces.

It involves the study and application of electrical properties of materials, components, and systems, and how they can be used to process, transmit, and store information and energy.
However, electronics have numerous applications in the medical field, such as in diagnostic equipment, monitoring devices, surgical tools, and prosthetics. In these contexts, "electronics" refers to the specific electronic components or systems that are used for medical purposes.
Silanes are a group of chemical compounds that contain silicon and hydrogen. The general formula for silanes is Si_xH_(2x+2), where x is a positive integer. Silanes are named after their parent compound, silane (SiH4), which contains one silicon atom and four hydrogen atoms.
Silanes are colorless and highly flammable gases at room temperature. They are typically prepared by the reaction of metal silicides with acids or by the reduction of halogenated silanes. Silanes have a variety of industrial applications, including as intermediates in the production of silicon-based materials such as semiconductors and polymers.
In medical contexts, silanes are not typically used directly. However, some silane-containing compounds have been investigated for their potential therapeutic uses. For example, some organosilanes have been shown to have antimicrobial properties and may be useful as disinfectants or in the development of medical devices. Other silane-containing materials have been studied for their potential use in drug delivery systems or as imaging agents in diagnostic procedures.
It is important to note that some silanes can be hazardous if not handled properly, and they should only be used by trained professionals in a controlled environment. Exposure to silanes can cause irritation to the eyes, skin, and respiratory tract, and prolonged exposure can lead to more serious health effects.

These properties can include physical attributes like roughness, smoothness, hydrophobicity or hydrophilicity, and electrical conductivity, as well as chemical properties like charge, reactivity, and composition.
In the field of biomaterials science, understanding surface properties is crucial for designing medical implants, devices, and drug delivery systems that can interact safely and effectively with biological tissues and fluids. Surface modifications, such as coatings or chemical treatments, can be used to alter surface properties and enhance biocompatibility, improve lubricity, reduce fouling, or promote specific cellular responses like adhesion, proliferation, or differentiation.
Similarly, in the field of cell biology, understanding surface properties is essential for studying cell-cell interactions, cell signaling, and cell behavior. Cells can sense and respond to changes in their environment, including variations in surface properties, which can influence cell shape, motility, and function. Therefore, characterizing and manipulating surface properties can provide valuable insights into the mechanisms of cellular processes and offer new strategies for developing therapies and treatments for various diseases.
Biosensing techniques refer to the methods and technologies used to detect and measure biological molecules or processes, typically through the use of a physical device or sensor. These techniques often involve the conversion of a biological response into an electrical signal that can be measured and analyzed. Examples of biosensing techniques include electrochemical biosensors, optical biosensors, and piezoelectric biosensors.
Electrochemical biosensors measure the electrical current or potential generated by a biochemical reaction at an electrode surface. This type of biosensor typically consists of a biological recognition element, such as an enzyme or antibody, that is immobilized on the electrode surface and interacts with the target analyte to produce an electrical signal.
Optical biosensors measure changes in light intensity or wavelength that occur when a biochemical reaction takes place. This type of biosensor can be based on various optical principles, such as absorbance, fluorescence, or surface plasmon resonance (SPR).
Piezoelectric biosensors measure changes in mass or frequency that occur when a biomolecule binds to the surface of a piezoelectric crystal. This type of biosensor is based on the principle that piezoelectric materials generate an electrical charge when subjected to mechanical stress, and this charge can be used to detect changes in mass or frequency that are proportional to the amount of biomolecule bound to the surface.
Biosensing techniques have a wide range of applications in fields such as medicine, environmental monitoring, food safety, and biodefense. They can be used to detect and measure a variety of biological molecules, including proteins, nucleic acids, hormones, and small molecules, as well as to monitor biological processes such as cell growth or metabolism.

Scanning electron microscopy (SEM) is a type of electron microscopy that uses a focused beam of electrons to scan the surface of a sample and produce a high-resolution image. In SEM, a beam of electrons is scanned across the surface of a specimen, and secondary electrons are emitted from the sample due to interactions between the electrons and the atoms in the sample. These secondary electrons are then detected by a detector and used to create an image of the sample's surface topography. SEM can provide detailed images of the surface of a wide range of materials, including metals, polymers, ceramics, and biological samples. It is commonly used in materials science, biology, and electronics for the examination and analysis of surfaces at the micro- and nanoscale.
A nanopore is a tiny, narrow opening or passage at the molecular level, with a diameter typically measured in nanometers (nm). In the context of medicine and biology, nanopores are often used to describe protein structures that form water-filled channels across lipid membranes. These nanopores allow for the selective transport of ions, small molecules, or RNA/DNA strands between intracellular and extracellular spaces.
Nanopore technology has gained significant attention in medical research due to its potential applications in single-molecule analysis, diagnostics, and targeted drug delivery. For instance, nanopores can be used for rapid DNA sequencing by threading individual DNA strands through the pore and detecting changes in ionic current as nucleotides pass through. This information can then be translated into a sequence of bases, providing valuable insights into genetic makeup and potential disease markers.
"Miniaturization" is not a term that has a specific medical definition. However, in a broader context, it refers to the process of creating smaller versions of something, usually with the aim of improving functionality, efficiency, or ease of use. In medicine, this concept can be applied to various fields such as medical devices, surgical techniques, and diagnostic tools.
For instance, in interventional radiology, miniaturization refers to the development of smaller and less invasive catheters, wires, and other devices used during minimally invasive procedures. This allows for improved patient outcomes, reduced recovery time, and lower risks of complications compared to traditional open surgical procedures.
Similarly, in pathology, miniaturization can refer to the use of smaller tissue samples or biopsies for diagnostic testing, which can reduce the need for more invasive procedures while still providing accurate results.
Overall, while "miniaturization" is not a medical term per se, it reflects an ongoing trend in medicine towards developing more efficient and less invasive technologies and techniques to improve patient care.
A Lab-on-a-Chip (LoC) device is a microfluidic system that integrates one or several laboratory functions on a single chip of only millimeters to a few square centimeters in size. These devices are designed to handle extremely small volumes of fluids, typically in the picoliter to microliter range, and perform various analytical operations such as sample preparation, separation, detection, and analysis.
LoC devices often incorporate different components like microchannels, reservoirs, pumps, valves, sensors, and biosensors to create a miniaturized laboratory environment. They offer numerous advantages over traditional laboratory methods, including faster analysis times, lower reagent consumption, reduced cost, higher throughput, enhanced portability, and improved automation.
LoC devices have found applications in various fields, such as clinical diagnostics, point-of-care testing, drug discovery and development, environmental monitoring, and basic research in areas like cell biology, proteomics, and genomics.

3. Microscope: A device that uses a system of lenses or mirrors to magnify objects or images, making them visible to the human eye. Microscopes are used in various medical fields, including pathology, hematology, and microbiology, to examine specimens such as tissues, cells, and microorganisms.
4. Endoscope: A flexible tube equipped with a light source and a camera that can be inserted into body cavities or passages to visualize internal structures. Endoscopes are used in procedures such as colonoscopy, gastroscopy, and laparoscopy to diagnose and treat conditions such as polyps, ulcers, and tumors.
5. Otoscope: A device used by healthcare professionals to examine the ear canal and eardrum. It typically consists of a handle, a light source, and a speculum that can be inserted into the ear canal to visualize the eardrum and identify any abnormalities such as inflammation, infection, or foreign bodies.
6. Refractor: A device used in optometry to measure the refractive error of the eye, or the amount of lens power needed to correct vision. The patient looks through a series of lenses while reading an eye chart, and the optometrist adjusts the lenses until the clearest vision is achieved.
7. Slit lamp: A microscope used in ophthalmology to examine the structures of the eye, including the cornea, iris, lens, and retina. The slit lamp uses a narrow beam of light to illuminate the eye and allow for detailed examination of any abnormalities or diseases.
"Comb" and "wattles" are terms used to describe fleshy appendages found in some animals, particularly birds. They are composed of skin and connective tissue, and are often brightly colored. While they don't have a direct medical definition, I can provide you with their general definitions:
1. Comb: In animals such as chickens, roosters, and other fowl, the comb is the fleshy, usually red, crown-like structure on top of the head. It varies in size and shape among different breeds and serves as a secondary sexual characteristic in males. The comb helps regulate body temperature and plays a role in courtship displays.
2. Wattles: These are the long, fleshy appendages that hang from either side of an animal's face or throat, often seen in conjunction with combs. Like combs, wattles are more prominent in males than females and serve as secondary sexual characteristics. They also play a role in thermoregulation and courtship displays.
While these structures are not typically associated with medical definitions, they can be subject to various health issues, such as frostbite, injuries, or infections. In those cases, veterinary medicine would address the specific health concerns related to combs and wattles.
