A parliamentary democracy with a constitutional monarch in southeast Asia, consisting of 11 states (West Malaysia) on the Malay Peninsula and two states (East Malaysia) on the island of BORNEO. It is also called the Federation of Malaysia. Its capital is Kuala Lumpur. Before 1963 it was the Union of Malaya. It reorganized in 1948 as the Federation of Malaya, becoming independent from British Malaya in 1957 and becoming Malaysia in 1963 as a federation of Malaya, Sabah, Sarawak, and Singapore (which seceded in 1965). The form Malay- probably derives from the Tamil malay, mountain, with reference to its geography.

Connectin, an elastic protein from myofibrils. (1/1192)

The elastic protein isolated from myofibrils of chicken skeletal muscle was compared with extracellular non-collagenous reticulin prepared from chicken liver and skeletal muscle. The amino acid compositions of these proteins were similar except that their contents of Phe, Leu, Cys/2, and Hyp were different. The impregnations of the elastic protein and reticulin with silver were also different. The reticulin was not at all elastic. It also differed from reticulin in solubility and antigenicity. It is proposed to call the intracellular elastic protein connectin.  (+info)

Adhesion of adhesive resin to dental precious metal alloys. Part I. New precious metal alloys with base metals for resin bonding. (2/1192)

New dental precious metal alloys for resin bonding without alloy surface modification were developed by adding base metals (In, Zn, or Sn). Before this, binary alloys of Au, Ag, Cu, or Pd containing In, Zn, or Sn were studied for water durability and bonding strength with 4-META resin. The adhesion ability of the binary alloys was improved by adding In equivalent to 15% of Au content, Zn equivalent to 20% of Ag content, and In, Zn, or Sn equivalent to 5% of Cu content. There was no addition effect of the base metals on Pd, however 15% of In addition improved adhesion with Pd-based alloys containing equi-atomic % of Cu and Pd. The alloy surfaces were analyzed by XPS and showed that oxides such as In2O3, ZnO, or SnO play an important role in improving the adhesive ability of the alloys.  (+info)

Perineuronal nets of proteoglycans in the adult mouse brain, with special reference to their reactions to Gomori's ammoniacal silver and Ehrlich's methylene blue. (3/1192)

As our previous studies have indicated, many subsets of neurons in the vertebrate brain possess a sulfated proteoglycan surface coat which reacts to cationic iron colloid and aldehyde fuchsin. The present study demonstrated that this surface coat is supravitally stained with Ehrlich's methylene blue, and doubly with this blue and aldehyde fuchsin, a finding suggesting its being identical to Cajal's superficial reticulum (red superficial) and to Golgi's reticular coating (revetement reticulare). The perineuronal surface coat was further stained with Gomori's ammoniacal silver, and doubly with this silver and cationic iron colloid. These neurons with such a proteoglycan surface coat usually expressed cell surface glycoproteins which were labeled with lectin Wisteria floribunda agglutinin. Hyaluronidase digestion did not interfere with this lectin labeling of the glycoproteins, methylene blue and Gomori's ammoniacal silver staining of the surface coat, while it erased the cationic iron colloid and aldehyde fuchsin staining of the surface coat. These findings suggest that the perineuronal proteoglycan surface coat is associated with some additional molecules which are resistant to hyaluronidase digestion and stainable with methylene blue and Gomori's ammoniacal silver. The possibility is suggested that these molecules might represent "ligand proteoglycans" connecting the perineuronal proteoglycans and cell surface glycoproteins.  (+info)

Modified hemoglobins produce venular interendothelial gaps and albumin leakage in the rat mesentery. (4/1192)

Cross-linked hemoglobin (alphaalpha-Hb) and polyethylene glycol (PEG)-conjugated Hb have both been considered as possible "blood substitutes." Previously, we showed that PEG-Hb extravasates rapidly in the intestinal mucosa and causes transient epithelial sloughing, resulting in temporary opening of the intestinal epithelial barrier. In the present study, the rat mesenteric preparation was used to quantify the effects of the two Hbs on microvascular leakage to albumin and to investigate possible changes in the integrity of the interendothelial cell junctions and the endothelial actin cytoskeleton. In anesthetized Sprague-Dawley rats, the microvasculature of a mesenteric window was perfused with HEPES-buffered saline (HBS) containing 0.5 mg/ml BSA and 2 mg/ml alphaalpha-Hb (n = 16) or PEG-Hb (n = 5) for 2 or 10 min. Controls (n = 4) just received HBS-BSA. In some experiments (n = 9 for alphaalpha-Hb; n = 5 for PEG-Hb), the perfusate was then replaced by FITC-albumin in HBS-BSA for the next 3 min. The vasculature was then perfusion fixed, stained for filamentous actin and for mast cells, and viewed microscopically. In the remaining experiments, the mesenteric microvasculature was stained with silver nitrate to determine the number of endothelial junctional gaps per length of venules. Both Hbs increased the number and area of leaks per micrometer of venular length compared with control, but alphaalpha-Hb increased to a greater extent than PEG-Hb. Formation of leaks was accompanied by changes in the endothelial actin cytoskeleton and by an increased number of endothelial gaps. Mast cell degranulation was significantly greater (P < 0.05) in Hb-treated preparations compared with controls, but there was no direct correlation between sites of degranulation and albumin leakage. These Hbs appear to induce venular leakage in the mesentery by mechanisms similar to those previously observed after treatment with histamine or nitric oxide synthase inhibitors.  (+info)

Silver-based crystalline nanoparticles, microbially fabricated. (5/1192)

One mechanism of silver resistance in microorganisms is accumulation of the metal ions in the cell. Here, we report on the phenomenon of biosynthesis of silver-based single crystals with well-defined compositions and shapes, such as equilateral triangles and hexagons, in Pseudomonas stutzeri AG259. The crystals were up to 200 nm in size and were often located at the cell poles. Transmission electron microscopy, quantitative energy-dispersive x-ray analysis, and electron diffraction established that the crystals comprise at least three different types, found both in whole cells and thin sections. These Ag-containing crystals are embedded in the organic matrix of the bacteria. Their possible potential as organic-metal composites in thin film and surface coating technology is discussed.  (+info)

Activities of a nitrofurazone-containing urinary catheter and a silver hydrogel catheter against multidrug-resistant bacteria characteristic of catheter-associated urinary tract infection. (6/1192)

The in vitro inhibitory activity of a nitrofurazone-coated urinary catheter (NFC) against 86 recently obtained susceptible and multidrug-resistant (MDR) clinical isolates of Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii, Staphylococcus aureus, coagulase-negative staphylococci, and Enterococcus faecium, which are species implicated in catheter-associated urinary tract infection and which traditionally have been susceptible to nitrofuran derivatives, was determined using an agar diffusion assay. In a subset of these strains, the activity of the NFC was compared with that of a silver hydrogel urinary catheter (SHC), and the durability of each catheter's inhibitory activity was assessed during serial daily transfers of catheter segments to fresh culture plates. Except for vancomycin-resistant E. faecium, the NFC was active against all isolates tested and showed comparable inhibition zones with susceptible and MDR strains of each species. In contrast, the SHC inhibited only certain staphylococci (P < 0.01 versus the NFC), and among these strains, the SHC produced smaller inhibition zones than did the NFC (P < 0.01). Inhibition was evident for up to 5 days with the NFC, but for only 1 day (if at all) with the SHC (P < 0.01). These data document that, for most genera which traditionally have been susceptible to nitrofuran derivatives, the NFC remains active against contemporary MDR isolates. They also demonstrate that the in vitro antibacterial activity of the NFC is markedly superior to that of the SHC in several respects. Thus, the NFC shows promise for clinical use in the current era of MDR bacteria.  (+info)

Four years of experience with silver-copper ionization for control of legionella in a german university hospital hot water plumbing system. (7/1192)

Silver-copper ionization was used for controlling Legionella distribution in a German university hospital hot water plumbing system for 4 years. In the beginning, silver concentrations were not allowed to exceed 10 microg/L because of drinking water regulation limits in Germany. Water samples were monitored for Legionella counts, temperature, and silver and copper concentrations. A significant (P<.001) 3.8-log reduction of Legionella counts, from 40, 000 cfu/L to 7 cfu/L, was found during the first year with silver-copper ionization. Nevertheless, the long-term efficacy of silver concentrations <10 ,++microg/L was not sufficient. Legionella counts increased to 10,000 cfu/L during the third year. During the fourth year, we studied the influence of higher silver concentrations on Legionella distribution. With an average silver level of 30 microg/L, only a 1.3-log reduction in Legionella, to 500 cfu/L, was achieved. The effect was not significant (P=.071); therefore, it must be considered that Legionella developed a tolerance to silver ions.  (+info)

DNA cleavage activities of (-)-epigallocatechin, (-)-epicatechin, (+)-catechin, and (-)-epigallocatechin gallate with various kinds of metal ions. (8/1192)

The DNA cleavage activities of (+)-catechin (C), (-)-epicatechin (EC), (-)-epigallocatechin (EGC), and (-)-epigallocatechin gallate (EGCg) were examined with 16 different metal ions. Cu(2+) with all the catechins facilitated DNA cleavage, while Ag+ with EGC and EC showed a strong repressive effect. The other metal ions examined showed little effect.  (+info)

AU - Ibrayev, N. Kh. AU - Afanasyev, D. A.. PY - 2016/11/28. Y1 - 2016/11/28. N2 - Influence of surface plasmon resonance of silver island films on photoinduced electronic processes in polymer films of poly(3-hexylthiophene-2,5-diyl) (P3HT) was studied in this work. Fabrication of P3HT on the surface of the plasmon silver island films increases intensity of the absorption and fluorescence of the polymer film about 4 times. The increase in absorption and fluorescence intensity of P3HT is associated with an increase of the rate of absorption transitions in the polymer films through the influence of the local electromagnetic field near the surface of the silver island films. A formation of disordered polymer structures occurs on the surface of the silver island films. This is determined from the ...
The effects of silver nanoparticle on the physical properties of syndiotactic polypropylene (sPP) were investigated in terms of rheological responses and crystallization behavior under shear. Silver nanoparticle played as the nucleating agent of sPP by increasing crystallization temperature (Tc) and heat of crystallization (ΔHc). The introduction of silver nanoparticles more than 1 wt% brought about the rise of dynamic viscosity when compared to pure sPP. sPP with 5 wt% silver nanoparticle exhibited the higher tan δ and lower relaxation time than the others in the low frequency range. However, the effects of silver nanoparticle on the rheological properties became less noticeable when the loading level was higher than 5 wt%.
We study the effect of plasmon excitations in silver island film on the optical properties of peridinin-chlorophyll-protein light-harvesting complex using scanning fluorescence microscopy. With this technique we can unambiguously locate areas where the biomolecules are deposited on the metallic nanostructures from the areas where they stick to the glass surface. The enhancement factor of fluorescence intensity obtained for such a hybrid nanostructure is found to be 3. Plasmon excitations in the SIF layer also influence the dynamics of the emission, but in this case the interpretation of the results is more complex ...

The different morphologies of AgPt thin films were grown on the surface using 0.1 mM to 0.8 mM of silver concentration. This silver effect on the growth of AgPt on the surface was studied using FESEM and UV-Vis characterization. It was found that the optimum silver concentration in synthesis solution supplied the appropriate Ag+ ion to grow the nanoferns structure on the surface. AgPt films were then carried out to sense 1.0 M of creatinine concentration to learn their performance as surface-enhanced Raman scattering (SERS) substrate. ...
The myth that colloidal silver can turn your skin a bluish color is absolutely only a myth when taken as prescribed by a doctor. The media created a campaign to frighten viewers from using products containing colloidal silver. The man, Paul Karason, described as the Blue Man was attempting to create colloidal silver at home. What he actually created was not truly Colloidal Silver but a high concentrated ionic silver solution. He mixed salt into the solution and used electrolysis, which created a high concentration of silver chloride. Since he believed that he had made a colloidal silver solution he rubbed it on his skin. The solution caused his skin to turn a bluish color. The use of silver solutions began in the late 1800s. It was used as a topical antiseptic. Although, Colloidal Silver is not readily used today among health professionals, there are many states that still require hospitals to use Silver Nitrate to prevent eye infections in newborns. Colloidal Silver must be taken as ...
Article Silver nanoparticle toxicity to Daphnia magna is a function of dissolved silver concentration. The most persistent question regarding the toxicity of silver nanoparticles (AgNPs) is whether this toxicity is due to the nanoparticles themselves...
Silver nanoparticles have been shown to inhibit viruses. However, very little is known about the mechanism of antiviral activity. This study tested the hypothesis that 25-nm silver nanoparticles inhibited Vaccinia virus replication by preventing viral entry. Plaque reduction, confocal microscopy, and beta-galactosidase reporter gene assays were used to examine viral attachment and entry in the presence and absence of silver nanoparticles. To explore the mechanism of inhibition, viral entry experiments were conducted with silver nanoparticles and small interfering RNAs designed to silence the gene coding for p21-activated kinase 1, a key mediator of macropinocytosis. The silver nanoparticles caused a 4- to 5-log reduction in viral titer at concentrations that were not toxic to cells. Virus was capable of adsorbing to cells but could not enter cells in the presence of silver nanoparticles. Virus particles that had adsorbed to cells in the presence of silver nanoparticles were found to be infectious upon

Silver nanoparticles have been found many interesting applications, such as absorption amplifiers in dye-sensitized solar cells. However, silver nanoparticles are easily oxidized. In order to protect silver nanoparticles, atomic layers of TiO2were deposited onto silver nanoparticles coated to a glass slide. Then the glass slide was exposed to corrosive I-/I3- solutions, and the degree of silver etching was measured via scanning electron microscopy (SEM) and ultraviolet-visible spectroscopy (UVS). It was found that 3 nm (30 cycles) of Al2O3 with 9 nm of (90 cycles) TiO2 could completely protect silver nanoparticles from oxidization ...
Many studies addressing the toxicity of silver nanomaterials have found that smaller sized silver nanoparticles are usually more toxic to organisms and in cell culture than particles of larger sizes yet it is not entirely clear why. We investigated the size dependent toxicity of silver nanoparticles by measuring the response of embryonic zebrafish (Danio rerio) following exposure to a library of thirteen distinct silver nanoparticle size distributions with mean diameters between 8.9 nm and 112.6 nm. Data analysis using dose‐response modeling revealed that silver nanoparticles (AgNP) induced embryo toxicity that is dependent on the total surface area and not on the mass or particle number in solution. Included in this study is a comparison between embryo toxicity induced by silver nitrate (AgNO₃) and AgNPs for cardiovascular endpoints, as well as an investigation into the influence of the chorion on AgNP toxicity. This study demonstrates the importance of using alternative dose metrics in ...
1. The International Space Station Uses Silver to Purify Water. Hospitals have begun using filters containing silver to kill MRSA and other harmful organisms. Even the World Health Organization uses silver and colloidal silver in water filters to disinfect water in developing countries.

Although colloidal silver has been used for medicinal purposes for many centuries, in recent years it has come back into circulation. The traditionally claimed benefits of colloidal silver can now be tested by modern science. Recently the UCLA School of medicine conducted medical tests on colloidal silver.. The laboratory tests conducted by Larry C. Ford, the M.D of the Department of Obstetrics and Gynecology from UCLA School of Medicine brought to light the ability of colloidal silver to kill viral, fungal and bacterial organisms.. The individual conducted extensive laboratory tests based on the standard anti-microbial test for disinfectants. The results showed colloidal silver to have anti-bacterial properties for 105 organisms per ml of streptococcus pyogenes, Neisseria, Gardnerella Vaginalis, Gonorrhea and various other enteric pathogens.. Thus it was discovered that colloidal silver can actually kill over 650 bacteria, fungi, parasites, molds and fungi that have the potential to sprout ...

The use of less hazardous chemicals or natural material in place of toxic chemical for the formation of metal nanoparticle is known as green synthesis. The present paper deals with greener approach for the synthesis of silver (Ag) nanoparticles. The Saraca asoca plant leaves extract solution was used for the silver nanoparticles. Confirmation of Ag nanoparticles has been done using various characterization techniques viz. structural by X-Ray Diffraction (XRD), morphological analysis by Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and elemental analysis by Energy Dispersive X-ray Spectroscopy (EDX). The particle size of silver nanoparticle is found to be 24.85 nm. The particle exhibits good antibacterial properties against Staphylococci aures, Streptococci pyogens, Salmonella typhi.
Synthesized thiolate boronic acid was found to complex with both a polysaccharide (dextran) and a monosaccharide (glucose) with similar affinities but displayed more affinity with dextran than with glucose when capped as a ligand on silver nanoparticle. Coupling on multiple sites of dextran, the silver particles were aggregated. The aggregated particles displayed a decrease of absorbance at 397 nm and an increase at 640 nm. Luminescence intensity displayed an upward deviation increase with the concentration of dextran. The luminescence spectral change was ascribed to surface-enhanced fluorescence by the enhanced field from the aggregated metallic particles.
ACS 200 Extra Strength. • ACS 200 Extra Strength is the most powerful silver formulation today with over 500 University and Laboratory studies documenting efficacy.. Why is ACS 200 extra strength so effective? ACS 200 Extra Strength achieves a much greater kill power than other silver brands for many reasons.. A much higher concentration of silver ions: A huge difference between ACS 200 Extra Strength and other silvers is the increased amount of silver ions in it. It is the silver ions which attach to pathogens and thus kill them. It is the silver ions that provide healing benefit to living, mammalian cells. Simply stated, ACS 200 Extra Strength contains far more silver ions than competing brands.. ACS 200 is the only silver with long-lasting silver ion production: Other silver products provide a limited number of silver ions, these are highly unstable and have a very short lifespan on the body.

The Perkin Elmbver Model 303, equipped with the DCR-1, digital concentration readout, was evaluated as to its ability to provide an index of silver concentration in water solutions, without concentrating in any manner. The procedures, principal settings, and adjustments which must be observed are described. This instrument can detect the difference between concentrations of 10-15 and 10-12 gm/ml. However, as the concentration of silver decreases the experimental error increases to a point at which the error becomes greater than the differences in readout due to differences in silver concentration.

A novel electrode modified with silver nanoparticles was fabricated. It is found that the reducibility of silver nanoparticles is higher than for bulk silver by comparing a silver nanoparticles modified electrode with a silver micro-disk electrode. When SCN- was added, a new oxidation peak occurred and the anodic peak current of silver nanoparticles decreased. The new anodic peak current is proportional to the thiocyanate concentration in the range of 5.0×10-7~4.0×10-4 mol/L in pH 6.0 NaH2PO4-Na2HPO4 buffer solutions (PBS). The detection limit (S/N=3) is 4×10-8 mol/L. This method has been applied to the determination of saliva (smoker and non-smoker).

Most colloidal silver items only contain 10% charged silver, but greater brands such as Sovereign Silver includes 98% positively charged silver. Does colloidal silver function? There are a lot of conflicting opinions out there, so its critical to have an understanding of how colloidal silver works. Pseudomonas aeruginosa is a typical bacterium that can lead to illnesses in humans. Research have discovered that up to 12% of silver has been discovered in Pseudomonas aeruginosa. In other words, silver can enter bacterial DNA, and it does so without destroying the hydrogen bonds and it prevents the DNA from unwinding.. Silver attaches to oxygen molecules, and reacts with the sulfhydral (H) groups that surround viruses and bacteria. This is thought to aid block cellular respiration, a life-preserving cellular procedure. Cellular respiration is a series of metabolic processes and reactions in cells which convert energy from nutrients into adenosine triphosphate prior to releasing waste merchandise. ...

Silver halides are used in photographic film and photographic paper, including graphic art film and paper, where silver halide crystals in gelatin are coated on to a film base, glass or paper substrate. The gelatin is a vital part of the emulsion as the protective colloid of appropriate physical and chemical properties. The gelatin may also contain trace elements (such as sulfur) which increase the light sensitivity of the emulsion, although modern practice uses gelatin without such components. When absorbed by an AgX crystal, photons cause electrons to be promoted to a conduction band (de-localized electron orbital with higher energy than a valence band) which can be attracted by a sensitivity speck, which is a shallow electron trap, which may be a crystalline defect or a cluster of silver sulfide, gold, other trace elements (dopant), or combination thereof, and then combined with an interstitial silver ion to form a silver metal speck.[1] When a silver halide crystal is exposed to light, a ...

Others may well have heard about it but have no thought what the term basically signifies and how it works. As it turns out, silver colloids are especially useful mixtures which are widely made use of in laboratories all around the planet. The term colloidal silver was coined in the course of the 1990s to describe a mixture containing silver nanoparticles whose silver content totals more than 50% of the mixture. Even so, exactly where lots of businesses have come unstuck is in labelling their items as colloidal silver, devoid of undergoing the detailed and usually pricey laboratory course of action to decide the exact levels of silver in their items. Several companies have advertised silver colloids, when the actual product on the shelves may well be practically nothing of the sort.. So, how can you inform if a item is a correct colloid or not? There are a handful of telltale indicators which show when the silver content of a remedy is significantly less than half. If the colour of a solution is ...
Hello Saregamapa, Silver does indeed possess antibacterial properties. It is used today as coatings on bandages, urinary catheters, heart stents and more, to help prevent surface bacterial growth. Silver nitrate drops were used in newborn?s eyes to prevent infection. Taking colloidal silver by mouth is another matter however, and a questionable practice. There is no legitimate or scientific research proving that taking colloidal silver supplements is beneficial. The US and Australian governments warn against falling for such scams. ?Throughout history, people have exploited the germicidal properties of silver. The Greeks and Romans stored water and other drinks in silver vessels that were believed to keep the liquids fresh. During the plagues in Europe, wealthy families ate from silver plates and used silver utensils, in the hope that silver might protect them from the disease that was claiming their neighbors lives. Pioneers traveling across the U.S. placed silver and copper coins in their ...
The photoinduced growth reaction of silver nanoparticles was accelerated by reduced graphene oxide (RGO) produced from graphene oxide (GO) during the light irradiation process in aqueous solution. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy demonstrated that RGO was generated in the photoinduced process. The acceleration effect of RGO was investigated through monitoring the extinction spectra of silver nanoparticles during the synthesis process. Moreover, transmission electron microscopy (TEM) was employed to characterize the evolution of morphologies of silver nanoparticles at different irradiation times to demonstrate the effect of RGO. The results indicate that RGO accelerates the photoinduced synthesis of silver nanoparticles. It is proposed that the acceleration effect of RGO on the photoinduced reaction is attributed to the particular property of high electronic conductivity ...
Indian researchers have employed a single-step environmental friendly approach to synthesize silver nanoparticles. According to their report the biomolecules found in plants induce the reduction of Ag+ ions from silver nitrate to silver nanoparticles (AgNPs). The process of reduction is extra cellular and fast leading to the development of easy biosynthesis of silver nanoparticles. Plants during glycolysis produce a large amount of H+ ions along with NAD which acts as a strong redoxing agent which is responsible for the formation of AgNPs. Water-soluble antioxidative agents like ascorbic acids are further responsible for the reduction of AgNPs. These AgNPs produced show good antimicrobial activity against common pathogens ...

The present investigation was aimed to study the biosynthesis, stability and characterization of silver nanoparticles using Achyranthes aspera root extract. Synthesis of silver nanoparticles has been done by maintaining different AgNO3 concentrations (0.50, 1.00, 1.50 and 1.84 mM), temperature (25, 45, 75, 105 and 125 ºC) and pH conditions (4, 5, 7, 9 and 10). By analysing the data obtained during stability study, it was found that, combination of AgNO3 of 1.15 mM concentration, temperature at 45 ºC and pH of 9 was the best condition to synthesize the stable Ag NPs for one month. Characterization of synthesized silver nanoparticles was done by zetasizer, UV-Vis spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD) and atomic force microscopy (AFM). Particle size distribution of zetasizer indicated that the size of the biosynthesized silver nanoparticles was 23.21 nm and UV-Vis spectroscopy showed its absorbance peak at 420 nm, which confirmed the presence of Ag NPs.

Colloidal silver has been around a long time. It was used extensively in the 20th century until antibiotics became popular and relegated the use of silver in general to relative obscurity. Colloidal silver wasnt patentable; drugs were. Profits were made in selling a patented product. And some silver compounds had side effects if used improperly. They could cause argyria, a cosmetic skin condition which could cause the skin to turn a blue/gray color. With the present day problems of bacteria becoming resistant to antibiotics, colloidal silver is making a resurgence in popularity and use. One of the reasons for the renewed interest is the fact that bacteria and viruses are not resistant to contact with silver. Colloidal silver may be the magic bullet for mankind if antibiotics are no longer useful. Colloidal silver was used to cure and/or treat many diseases before being replaced with antibiotics.. What was thought to be the end of infectious diseases was accomplished in the 1940s. With the ...
In the Targeted National Sewage Sludge Survey, a 2009 test of 84 samples of sewage sludge from around the U.S., the EPA found silver in every sample in concentrations ranging from 1.94 to 856 parts per million.[8]. In comments to the EPA, officials from the sewage industry expressed concern about the increased use of silver, particularly nanosilver, as a pesticide in household products.[9] The comments note that when the wastewater treatment plant is successful at removing silver from wastewater, all that does is remove the silver from the effluent only to put it into sewage sludge. The sewage industry worries that high concentrations of silver in sewage sludge will make them unable to dispose of sludge via land application. The letter says: Widespread use of household products that release silver ions into sanitary sewer systems could increase silver concentrations in POTW influents, effluents, and biosolids. If silver pesticide product use becomes common, wastewater silver discharges could ...
Silver ions undergo reduction reactions induced by radiolytically produced products of tert-butanol, a commonly used solvent and scavenger for hydroxyl radicals. Radiolytic reduction of silver ions and the subsequent formation of their clusters are compared with the corresponding processes in aqueous solution. The surface plasmon UV-Vis absorption band of silver nanocrystallites obtained by bombardment of tert-butanol solutions of silver salts with electron pulses showed an absorption maximum at 400 nm. Formation of different sizes of silver nanoparticles was found to be dependent on the dose rate. The nanocrystallites were found to have an average size of 20 nm.
Firstly, almost all studies that were done on the antibacterial and viral effects of silver were done in vitro, or in a petri dish. The human body is not a petri dish and there are far more factors at play in the human body. As Quackwatch writes, the fact that a product inhibits bacteria in a laboratory culture doesnt mean it is effective (or safe) in the human body. In fact, products that kill bacteria in the laboratory would be more likely to cause argyria because they contain more silver ions that are free to deposit in the users skin.. Furthermore, the National Institute of Health states that silver has no known function or benefits in the body when taken by mouth and that there are no legally marketed prescription or over-the-counter drugs containing colloidal silver that are taken by mouth.. The NIH also states that taking colloidal silver has several potentially serious side effects, including argyria, the discoloration of the skin, which is usually permanent.. The FDA, the ...

University of Southern Denmark. Endocrine disrupters are not the only worrying chemicals that ordinary consumers are exposed to in everyday life. Also nanoparticles of silver, found in e.g. dietary supplements, cosmetics and food packaging, now worry scientists. A new study from the University of Southern Denmark shows that nano-silver can penetrate our cells and cause damage.. Silver has an antibacterial effect and therefore the food and cosmetic industry often coat their products with silver nanoparticles. Nano-silver can be found in e.g. drinking bottles, cosmetics, band aids, toothbrushes, running socks, refrigerators, washing machines and food packagings.. Silver as a metal does not pose any danger, but when you break it down to nano-sizes, the particles become small enough to penetrate a cell wall. If nano-silver enters a human cell, it can cause changes in the cell, explain Associate Professor Frank Kjeldsen and PhD Thiago Verano-Braga, Department of Biochemistry and Molecular Biology ...

Here, we have synthesized the silver nanoparticles (AgNPs) by using the soil fungus Aspergillus niger 2587. The results recorded from UV-vis spectrophotometer and transmission electron microscopy (TEM) support the biosynthesis and characterization of AgNPs. The synthesized silver nanoparticles have also been tested against the larvae and pupae of Anopheles stephensi, Culex quinquefasciatus and Aedes aegypti. The efficacy test was performed at different concentrations for a period of different hours by the probit analysis. The larvae of Cx. quinquefasciatus have shown the 100% mortality to the synthesized AgNPs after 1 h of exposure, while the larvae of An. stephensi and Ae. aegypti were found less susceptible to the synthesized AgNPs. The pupa of Ae. aegypti has shown the efficacy LC50 4, LC90 12 and LC99 19 ppm after 2 h of exposure of the synthesized AgNPs, while, the pupae of Cx. quinquefasciatus and An. stephensi were found less susceptible to the synthesized AgNPs. By this approach, it is
The ordinary Raman scattering (ORS) spectra of virion protein of Granulosis Virus of Cabbage Butterfly Preris rapae (PrGV-VP) and their surface-enhanced Raman scattering (SERS) spectra adsorbed on the surface of silver colloid particles have been found that the Raman signal in the SERS spectra was enhanced by a factor of about 8 X 102. In ORS spectra of PrGV-VP, it indicates that PrGV-VP has a predominantly random-coil secondary structures. All tyrosine residues are exposed. And the PrGV-VP has a gauche-gauche- gauche configuration of the C-C-S-S-C-C linkage. In SERS spectra of PrGV-VP, the intensities of bands related to COO group and NH2 group vibrations are relatively strong. We interpret that the PrGV-VP are adsorbed on the Ag surface through both the carboxylate groups and the amino groups. The efficient enhancement of amide I and amide II vibrations are impeded, because the peptide groups of PrGV-VP are screened by the side-chains amino acid residues. The Raman enhancement of PrGV-VP has a ...

The synthesis of silver nanoparticles (AgNPs) by microorganisms is an area attracting growing interest in nanobiotechnology, due to the applications of these nanoparticles in various products including cosmetics and biosensors, and in the biomedical, clinical, and bioimaging fields as well. Various microorganisms have been found to be able to synthesize AgNPs when silver salts are supplied in the reaction system. The main objectives of this study were to evaluate the efficiency of synthesis of AgNPs by the strain Bacillus methylotrophicus DC3, isolated from the soil of Korean ginseng, a traditionally known oriental medicinal plant in Korea. The AgNPs showed maximum absorbance at 416 nm, when assayed by ultraviolet-visible spectroscopy (UV-vis). The field emission transmission electron micrograph (FE-TEM) results showed that the particles were spherical and 10-30 nm in size. In addition, the product was also characterized by energy dispersive X-ray spectroscopy (EDX), which displayed a 3 keV peak
Background: Silver-based products have been marketed as an alternative to antibiotics, and their consumption has increased. Bacteria may, however, develop resistance to silver. Aim: To study the presence of genes encoding silver resistance (silE, silP, silS) over time in three clinically important Enterobacteriaceae genera. Methods: Using polymerase chain reaction (PCR), 752 bloodstream isolates from the years 1990-2010 were investigated. Age, gender, and ward of patients were registered, and the susceptibility to antibiotics and silver nitrate was tested. Clonality and single nucleotide polymorphism were assessed with repetitive element sequence-based PCR, multi-locus sequence typing, and whole-genome sequencing. Findings: Genes encoding silver resistance were detected most frequently in Enterobacter spp. (48%), followed by Klebsiella spp. (41%) and Escherichia coli 4%. Phenotypical resistance to silver nitrate was found in Enterobacter (13%) and Klebsiella (3%) isolates. The lowest carriage ...
April Flowers for redOrbit.com - Your Universe Online. When is your skin like a black and white photograph? Sounds like the start to a bad riddle, right? Instead, its the essential question behind a new study from Brown University. The study shows, for the first time, how ingesting too much silver can cause argyria, which is a rare condition that turns a patients skin a striking shade of grayish blue.. Its the first conceptual model giving the whole picture of how one develops this condition, said Robert Hurt, professor of engineering at Brown. Whats interesting here is that the particles someone ingests arent the particles that ultimately cause the disorder.. Its been known for years that silver had something to do with argyria. Argyria has been documented in patients who have undergone alternative treatments involving silver and people who - ill advisedly - drink antimicrobial health tonics containing silver nanoparticles. Researchers have found silver particles lodged deep in the ...

In soybean seed coats the accumulation of the hydroxyproline-rich glycoprotein extensin is regulated in a developmental and tissue-specific manner. The time course of appearance of extensin during seed development was studied by Western blot analysis and by immunogold-silver localization. Using these techniques extensin was first detected at 16-18 d after anthesis, increasing during development to high levels at 24 d after anthesis. Immunogold-silver localization of extensin in the seed coat showed marked deposition of the glycoprotein in the walls of palisade epidermal cells and hourglass cells. The immunolocalization of extensin in developing soybean seeds was also made by a new technique--tissue printing on nitrocellulose paper. It was found that extensin is primarily localized in the seed coat, hilum, and vascular elements of the seed. ...

In early 2006, silver launched into a far-more-extreme parabola than we saw this year. Silver rocketed 124% higher from August 2005 to May 2006! It was a wonderful and highly-profitable episode for silver enthusiasts. Comparing this parabola and its aftermath with 2008 s parabola and aftermath really builds an impressive bullish case for silver. Note above that these two events even look very similar on the chart.. The 2006 parabola was bigger and badder than 2008 s by any measure. It soared 124.0% over 9 months compared to 80.5% over 7 months ending March 2008. In its terminal stage in spring 2006, traders drove silver up so fast that it stretched 1.704x and 1.651x above its 200-day moving average at its twin tops. Such stellar rSilver (silver divided by its 200dma) multiples reveal the euphoria surrounding the May 2006 top.. Back then, traders were actually excited about silver and silver stocks. If you were trading the silver complex around that May 2006 top, you are well aware of the vast ...
