Three-independent-compartment chamber to study in vitro commissural synapses. (1/863)We describe a novel chamber in which the two intact neonatal rat hippocampi and the commissural fibers are placed in three independent compartments separated by latex membranes and perfused selectively with different solutions. A set of control tests showed that the compartments are well isolated: 1) methylene blue or eosin applied to one compartment did not diffuse to other compartments when verified via the microscope, and spectrophotometry revealed that <1/10.000th of the dye diffuses to other compartments; 2) tetrodotoxin (1 microM) applied to the commissural compartment blocked the synaptic responses evoked contralaterally without affecting those evoked on the ipsilateral side. This chamber enables a wide range of experiments that cannot be performed in conventional chambers, e.g., to study the maturation and plasticity of the commissural connections, bilateral synchronization of the rhythmic activities in the limbic system, commissural propagation of the epileptiform activities, etc. (+info)
The influence of NO synthase inhibitor and free oxygen radicals scavenger--methylene blue--on streptozotocin-induced diabetes in rats. (2/863)The excessive production of nitric oxide (NO) and the subsequent increase of local oxidative stress is suggested as one of the pathophysiological mechanisms of streptozotocin-induced diabetes. It was reported that the administration of NO synthase inhibitors partially attenuated the development of streptozotocin-induced diabetes and reduced hyperglycaemia. Here we have studied the influence of methylene blue, which combines the properties of NO synthase inhibitor with antioxidant effects. The experiments were performed on male rats divided into four groups: control, diabetic (single dose of 70 mg of streptozotocin/kg i.p.), methylene blue (50 mg/kg in the food) and diabetic simultaneously fed with methylene blue. After 45 days the experiments were discontinued by decapitation. Serum glycaemia, glycated haemoglobin and oxidative stress parameters (plasma malondialdehyde concentration and erythrocyte superoxide dismutase activity) were significantly higher in the diabetic group. Simultaneous methylene blue administration partially reduced glycaemia and glycated haemoglobin, but did not decrease oxidative stress. We conclude that NO synthase inhibitor methylene blue partially attenuates the development of streptozotocin-induced diabetes in male rats, but does not reduce the development of oxidative stress in the diabetic group.

Detection of small numbers of immature cells in the blood of healthy subjects. (3/863)AIMS: To determine the frequency of immature haemopoietic cells in the peripheral blood of healthy persons. METHODS: Cytocentrifuge preparations were made using mononuclear leucocytes separated by a Ficoll-Hypaque density gradient. The slides were stained by May-Grunwald-Giemsa. The combination with immunoperoxidase technique allowed immunotyping of uncommon blood cells. RESULTS: Blast cells expressing the progenitor cell marker CD34 represented 0.11 (0.06) per cent (mean (SD)) of the total mononuclear leucocyte count; these were the haemopoietic progenitor cells in the peripheral blood. Dark blue cells expressing CD38, CD45, HLA-DR, CD4, CD11a, CD29, CD49d, CD50, and CD54 represented 0.30 (0.21) per cent of the mononuclear leucocytes; most of these cells did not express T, B, NK, myelomonocytic, progenitor cell, proliferation, activation, blood dendritic cell, or follicular dendritic cell markers. These were dendritic cell precursors in the peripheral blood. Very small numbers of cells expressing CD83 were found. Blast-like cells expressing CD45, HLA-DR, CD11a, and CD50 represented 0.15 (0.10) per cent of the mononuclear leucocytes; morphology and immunotyping supported the conclusion that these cells were poorly differentiated monocytes. CONCLUSIONS: Morphological investigation of mononuclear leucocytes in peripheral blood of healthy persons can be used to detect small numbers of blasts, dark blue cells, and blast-like cells. The immunoperoxidase technique can then be used for immunotyping of these cells. This simple method may be helpful in diagnosing haematological disorders. (+info)
Endothelium-derived relaxing, contracting and hyperpolarizing factors of mesenteric arteries of hypertensive and normotensive rats. (4/863)Differences in the acetylcholine (ACh)-induced endothelium-dependent relaxation and hyperpolarization of the mesenteric arteries of Wistar Kyoto rats (WKY) and stroke-prone spontaneously hypertensive rats (SHRSP) were studied. Relaxation was impaired in preparations from SHRSP and tendency to reverse the relaxation was observed at high concentrations of ACh in these preparations. Relaxation was partly blocked by NG-nitro-L-arginine (L-NOARG, 100 microM) and, in the presence of L-NOARG, tendency to reverse the relaxation was observed in response to higher concentrations of ACh, even in preparations from WKY. The relaxation remaining in the presence of L-NOARG was also smaller in preparations from SHRSP. The tendency to reverse the relaxation observed at higher concentrations of ACh in preparations from SHRSP or WKY in the presence of L-NOARG were abolished by indomethacin (10 microM). Elevating the K+ concentration of the incubation medium decreased relaxation in the presence of both indomethacin and L-NOARG. Relaxation in the presence of L-NOARG and indomethacin was reduced by the application of both apamin (5 microM) and charybdotoxin (0.1 microM). This suggests that the relaxation induced by ACh is brought about by both endothelium-derived relaxing factor (EDRF, nitric oxide (NO)) and hyperpolarizing factor (EDHF), which activates Ca2+-sensitive K+ channels. Electrophysiological measurement revealed that ACh induced endothelium-dependent hyperpolarization of the smooth muscle of both preparations in the presence of L-NOARG and indomethacin; the hyperpolarization being smaller in the preparation from SHRSP than that from WKY. These results suggest that the release of both NO and EDHF is reduced in preparations from SHRSP. In addition, indomethacin-sensitive endothelium-derived contracting factor (EDCF) is released from both preparations; the release being increased in preparations from SHRSP. (+info)
Possible novel mechanism for bitter taste mediated through cGMP. (5/863)Taste is the least understood among sensory systems, and bitter taste mechanisms pose a special challenge because they are elicited by a large variety of compounds. We studied bitter taste signal transduction with the quench-flow method and monitored the rapid kinetics of the second messenger guanosine 3',5'-cyclic monophosphate (cGMP) production and degradation in mouse taste tissue. In response to the bitter stimulants, caffeine and theophylline but not strychnine or denatonium cGMP levels demonstrated a rapid and transient increase that peaked at 50 ms and gradually declined throughout the following 4.5 s. The theophylline- and caffeine-induced effect was rapid, transient, concentration dependent and gustatory tissue-specific. The effect could be partially suppressed in the presence of the soluble guanylyl cyclase (GC) inhibitor 10 microM ODQ and 30 microM methylene blue but not 50 microM LY 83583 and boosted by nitric oxide donors 25 microM NOR-3 or 100 microM sodium nitroprusside. The proposed mechanism for this novel cGMP-mediated bitter taste signal transduction is cGMP production partially by the soluble GC and caffeine-induced inhibition of one or several phosphodiesterases.

Inhibition and stimulation of long-chain fatty acid oxidation by chloroacetaldehyde and methylene blue in rats. (6/863)The effects of chloroacetaldehyde (CAA) and methylene blue, both alone and together, on mitochondrial metabolism, hepatic glutathione content, and bile flow were investigated in rats. Oxidation of [1-14C]palmitic acid, [1-14C]octanoic acid, and [1,4-14C]succinic acid allowed for the differentiation between carnitine-dependent long-chain fatty acid metabolism, medium chain fatty acid oxidation, and citric acid cycle activity, respectively. CAA, a metabolite of the anticancer drug ifosfamide, which may be responsible for ifosfamide-induced encephalopathy, inhibited palmitic acid metabolism but not octanoic or succinic acid oxidation, depleted hepatic glutathione, and stimulated bile flow. Methylene blue, which is clinically used to either prevent or reverse ifosfamide-associated encephalopathy, markedly stimulated palmitic acid oxidation either in the presence or absence of CAA, but did not affect the oxidation of octanoic and succinic acid or hepatic glutathione. Taken together, this study demonstrates that CAA inhibits palmitic acid metabolism. Methylene blue stimulates long-chain fatty acid oxidation, most likely by facilitating the translocation of fatty acids into mitochondria, and compensates for the CAA effect in vivo. (+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. (7/863)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)
Antinociceptive mechanism of Gosha-jinki-gan in streptozotocin-induced diabetic animals: role of nitric oxide in the periphery. (8/863)Using streptozotocin-induced diabetic mice and rats, we evaluated the antinociceptive mechanism of Gosha-jinki-gan. The antinociceptive effect of Gosha-jinki-gan (0.3 g/kg, p.o.) in diabetic mice, as determined by the tail-pressure test, was inhibited by N(G)-nitro-L-arginine methyl ester (L-NAME; 2, 5 mg/kg, i.p.). When L-NAME (10 microg) or methylene blue (500 microg) was topically administered to the intraplantar area of the hind paw, the region used for the paw-pressure test, the antinociceptive activity of Gosha-jinki-gan (0.3 g/kg, p.o.) in diabetic rats was decreased. These results suggested that the antinociceptive effect of Gosha-jinki-gan partly resulted from the peripheral action of increasingly produced nitric oxide. (+info)

The quite efficient adsorption of methylene blue dye from an aqueous solution by graphene oxide was studied. The favorable electrostatic attraction is the main interaction between methylene blue and graphene oxide. As graphene oxide has the special nanostructural properties and negatively charged surface, the positively charged methylene blue molecules can be easily adsorbed on it. In the aqueous solution of methylene blue at 293 K, the adsorption data could be fitted by the Langmuir equation with a maximum adsorption amount of 1.939 mg/mg and a Langmuir adsorption equilibrium constant of 18.486 mL/mg. The adsorption amount increased with the increase of the solution pH (3-11), was not affected significantly by KCl under the examined condition and the adsorption process was exothermic in nature. The fast and considerable adsorption of graphene oxide could be regarded as a potential adsorbent for cationic dye removal in wastewater treatment process ...
Senior study investigator Kan Cao and her team-Zheng-Mei Xiong, Mike ODonovan, Linlin Sun, Ji Young Choi, and Margaret Ren-published their findings late last month in the online journal Nature. The open-access article is titled Anti-Aging Potentials of Methylene Blue for Human Skin Longevity.. "Our work suggests that methylene blue could be a powerful antioxidant for use in skin care products," Dr. Cao, an associate professor of cell biology and molecular genetics at the University of Maryland, says in a press item from UMD. She goes on to emphasize that "the effects we are seeing are not temporary. Methylene blue appears to make fundamental, long-term changes to skin cells.". Commercial viability. The UMD researchers are so confident in their findings that methylene blue dye is an effective antioxidant, improves skin thickness and hydration, and increases elastin protein, among other benefits, that theyve moved ahead and are developing skin care product prototypes. "We have already ...

Adsorption of a basic dye, methylene blue, from aqueous solutions onto as-received activated carbons and acid-treated carbons was investigated. The physical and surface chemical properties of the activated carbons were characterized using BET-N(2) adsorption, X-ray photoelectron spectroscopy (XPS), and mass titration. It was found that acid treatment had little effect on carbon textural characteristics but significantly changed the surface chemical properties, resulting in an adverse effect on dye adsorption. The physical properties of activated carbon, such as surface area and pore volume, have little effect on dye adsorption, while the pore size distribution and the surface chemical characteristics play important roles in dye adsorption. The pH value of the solution also influences the adsorption capacity significantly. For methylene blue, a higher pH of solution favors the adsorption capacity. The kinetic adsorption of methylene blue on all carbons follows a pseudo-second-order ...
The amount of fine material available in the soil is significant in Atterberg limits and methylene blue tests. In the context of Atterberg limits, increased amount of clay minerals contained in the soil increases liquid and plastic limit values; however, increasing sand content reduces the moisture content reducing the water retention capacity of the soil which in return reduces the plasticity index (PI) value. In the case of methylene blue test, which is used to specify the quality of the amount of fine material, existence of clay in the medium increases the pollution level of the sand and the amount of methylene solution (V1) used. In this study, soil classes were determined and pollution rates were identified with Atterberg limits, pycnometer, sieve analysis, hydrometer analysis and methylene blue tests conducted on 11 different natural soil samples collected from different regions. From the data obtained, first the relationship between PI and methylene blue (MB) was examined and was evaluated

Methylene blue (MB) is a century-old drug with a newly discovered protective function in the ischemic stroke model. In the current investigation we studied the MB-induced neuroprotective mechanism focusing on stabilization and activation of hypoxia-inducible factor-1α (HIF-1α) in an in vitro oxygen and glucose deprivation (OGD)-reoxygenation model. Methods: HT22 cells were exposed to OGD (0.1% O2, 6h) and reoxygenation (21% O2, 24h). Cell viability was determined with the calcein AM assay. The dynamic change of intracellular O2 concentration was monitored by fluorescence ...
The researchers conducted a randomized, double-blinded, placebo-controlled clinical trial in which 26 healthy individuals aged 22 to 62 years were assigned to single-dose administration of methylene blue 280 mg or a blue food colorant as placebo.. The participants completed a psychomotor vigilance task to test sustained attention and a delayed match-to-sample task to measure short-term memory while undergoing fMRI, both before and 1 hour after administration of the study drug or placebo.. In addition, the impact of methylene blue on cerebrovascular reactivity was examined by determining cerebral blood flow during a carbon dioxide challenge before and after administration.. The results showed that during the psychomotor vigilance task, methylene blue was associated with significantly increased activity on fMRI in the bilateral anterior and posterior insular cortices during the attention phase (P = .01-.008).. In addition, methylene blue was associated with significantly increased fMRI activity ...
ZnS and CdS nanoparticles were prepared by a simple microwave irradiation method under mild conditions. The obtained nanoparticles were characterized by XRD, TEM and EDX. The results indicated that high purity of nanosized ZnS and CdS was successfully obtained with cubic and hexagonal crystalline structures, respectively. The band gap energies of ZnS and CdS nanoparticles were estimated using UV-visible absorption spectra to be about 4.22 and 2.64 eV, respectively. Photocatalytic degradation of methylene blue was carried out using physical mixtures of ZnS and CdS nanoparticles under a 500-W halogen lamp of visible light irradiation. The residual concentration of methylene blue solution was monitored using UV-visible absorption spectrometry. From the study of the variation in composition of ZnS:CdS, a composition of 1:4 (by weight) was found to be very efficient for degradation of methylene blue. In this case the degradation efficiency of the photocatalyst nanoparticles after 6 h irradiation time was
A patient who ingested an aniline-containing material developed severe methemoglobinemia. The usual beneficial response from administering methylene blue was not obtained, and within 24 hours a marked hemolytic episode occurred. The patient was found to be glucose-6-phosphate dehydrogenase-deficient and was therefore unable to utilize methylene blue in the NADPH-dependent reduction of methemoglobin. The possible role of methylene blue in precipitating the hemolysis is also discussed. ...
The glass surface modification with 3-(mercaptopropyl) trimethoxysilane (MPTS), gold nano-particles (GN) and guanine rich single strand DNA (ss-DNA) was utilized as a novel and efficient platform for sensing trace concentration of methylene blue (MB) by an inexpensive spectrophotometric method. Methylene Blue (MB) can interact with the guanine base of single strand DNA and absorbed onto glass surface and its absorbance can be determined at λmax of MB. Increase in methylene blue absorbance was linear with an increase in MB concentration and can be viewed by the naked eye and detected by spectrophotometric method. The linear range of the developed biosensor for determination of MB was from 10 to 100 nmol L-1 with a detection limit of 4 nmol L-1. The fabricated spectrophotometric MB biosensor possessed excellent selectivity and good sensitivity.
Introduction: Chemotherapy still is the most effective way to control malaria, a major public health problem in sub-Saharan Africa. The large-scale use of the combination therapy artemether-lumefantrine for malaria treatment in Africa predisposes lumefantrine to emergence of resistance. There is need to identify drugs that can be used as substitutes to lumefantrine for use in combination therapy. Methylene blue, a synthetic anti-methemoglobinemia drug, has been shown to contain antimalarial properties, making it a candidate for drug repurposing. The present study sought to determine antiplasmodial effects of methylene blue against lumefantrine- and pyrimethamine-resistant strains of P. berghei. Methodology: Activity of methylene blue was assessed using the classical four-day test on mice infected with lumefantrine-resistant and pyrimethamine-resistant P. berghei. A dose of 45 mg/kg/day was effective for testing ED90. Parasitemia and mice survival was determined. Results: At 45 mg/kg/day, ...

Artifacts may result from improper handling and staining of smears. Avoid contact of smears and stains with water! Exposure of smears to formalin vapors causes a bluish background, making it more difficult to differentiate cells. Dont store formalin in the same area where staining is done. Also, dont package surgical pathology specimens with blood smears. Never store smears in a refrigerator or freezer, since water condensation, RBC lysis, and hemoglobin crystallization may occur. Always be sure a slide is completely dried before placing it in a sealed container.. New methylene blue is another stain useful for hematologic examination. It is an aqueous rather than alcohol-based stain (it does not fix cells and therefore it is not a permanent stain). New methylene blue can be used as a supravital stain to examine reticulocytes, or may be applied to dried smears. New methylene blue also is a handy stain for urine sediment and cytologic preparations.. Microscopic Evaluation of the Blood ...

Fibroblasts were cultured in vitro, and SM was applied with different concentrations (40, 80, 160 and 320 micrograms/ml) and time(the 1st, 2nd, 3rd, 4th and 5th days) to influence their autocrine. Unassembled immunoglobulin heavy chains are retained intracellularly by delayed folding of the C(H)1 ...
TY - JOUR. T1 - Methylene blue reduces Aβ levels and rescues early cognitive deficit by increasing proteasome activity. AU - Medina, David X.. AU - Caccamo, Antonella. AU - Oddo, Salvatore. PY - 2011/3. Y1 - 2011/3. N2 - Promising results have emerged from a phase II clinical trial testing methylene blue (MB) as a potential therapeutic for Alzheimer disease (AD), where improvements in cognitive functions of AD patients after 6 months of MB administration have been reported. Despite these reports, no preclinical testing of MB in mammals has been published, and thus its mechanism of action in relation to AD pathology remains unknown. In order to elucidate the effects of MB on AD pathology and to determine its mechanism of action, we used a mouse model (3xTg-AD) that develops age-dependent accumulation of Aβ and tau and cognitive decline. Here, we report that chronic dietary MB treatment reduces Aβ levels and improves learning and memory deficits in the 3xTg-AD mice. The mechanisms underlying ...
The goal of this dissertation was to investigate the memory retention effects of methylene blue (MB) in both appetitive and aversive memory tasks in rats. Methylene blue is a metabolic enhancer that improves memory retention in a variety of tasks including inhibitory avoidance, object recognition, spatial memory, and extinction of Pavlovian fear conditioning. Low dose MB has no side effects on behavior. MB works as a metabolic enhancer by increasing brain cytochrome oxidase activity and oxygen consumption. The first experiment was conducted to examine the effects of MB treatment in normal rats in the hole board spatial memory task, to determine if it could enhance memory of discrimination learning of rewarded versus non-rewarded trials. Subjects treated with MB discriminated better between rewarded and non-rewarded trials as compared to control subjects, indicated by a greater number of correct responses on rewarded trials than non-rewarded trials. The second experiment was conducted to ...

When University of Maryland researchers tested methylene blue on a 3D simulated model of skin, they found that it could actually make the skin look younger.
Methylene Blue, which belongs to the phenothiazine family of dyes, is a unique dye with a variety of useful properties. Despite its high extinction coefficient in the visible region (81,000 L/mol.cm), it is weakly fluorescent due to its high rate of intersystem crossing from the S1 excited state to the T1 triplet state. This property makes it an excellent photosensitizer, and it has been used extensively to produce highly reactive singlet oxygen. In DNA, singlet oxygen leads to the oxidation of guanosine, resulting in the formation of 8-oxo-dG. Methylene Blue was subsequently used to determine that DNA polymerase eta (Pol η) was responsible for bypassing this lesion during replication.1
Thyroid surgery has potential risks. Intraoperative organ (such as parathyroides) extraction and vascular or neural (such as recurrent nervus) injuries are most important ones.

Protocol: (source: http://www.e-biotek.com) Load 2-5X the amount of DNA that would give bands of moderate intensity on an ethidium bromide stained gel. Typically this is something on the order of 0.5-2.5 µg of a 1 kb fragment on a 30 ml 1% mini gel. These numbers are guess-timates so your milage may vary. Run the gel normally and then place in a 0.002% methylene blue (w/v, Sigma M-4159) solution in 0.1X TAE (0.004M Tris 0.0001 M EDTA) for 1-4 h at room temp (22°C) or overnight at 4°C. Diffusion of the DNA does not seem to be a problem for fragments as small as 100 bp (3% Nusieve:1%agarose gel). This avoids background issues associated with staining with 0.02% methylene blue for 30-60 min and then destaining for what seems to be forever If destaining is needed to increase the visibility of the bands place the gel in 0.1X TAE with gentle agitation changing the buffer every 30 - 60 min until you are satisfied with the degree of destaining. Notes: This method primarily eliminates the damage of ...

There is growing concern regarding the contribution of infilled turf fields on increased athlete infections. Abrasions that occur on these fields create a port of entry for pathogens such as Staphylococcus aureus that are present on the athletes skin or possibly on the fields surface. This study compares the occurrence of microbial populations on two infilled synthetic turf fields (year old turf vs. 6 year old turf) in three locations. Both fields were sampled once a week for at least 14 weeks (exact number varied on field and location) during the late summer and fall of a football season. Sites sampled included the sidelines, the middle of each field, and the end of each field. Tryptic Soy Agar was used to determine total microbial load, Mannitol Salt Agar for Staphylococcus, and Eosin Methylene Blue Agar to count the number of enteric organisms such as Escherichia coli. Much higher microbial populations were found on the older turf field with as much as a 104 increase over similar locations ...

After 24 hours of incubation, bacterial grown was noted on sheep blood agar (Image 2) but not the eosin methylene blue agar. A drop oxidase was positive as shown in Image 2. ...
Our work suggests that methylene blue could be a powerful antioxidant for use in skin care products," said Kan Cao, senior author on the study and an associate professor of cell biology and molecular genetics at UMD. "The effects we are seeing are not temporary. Methylene blue appears to make fundamental, long-term changes to skin cells.". The researchers tested methylene blue for four weeks in skin cells from healthy middle-aged donors, as well as those diagnosed with progeria-a rare genetic disease that mimics the normal aging process at an accelerated rate. In addition to methylene blue, the researchers also tested three other known antioxidants: N-Acetyl-L-Cysteine (NAC), MitoQ and MitoTEMPO (mTEM). In these experiments, methylene blue outperformed the other three antioxidants, improving several age-related symptoms in cells from both healthy donors and progeria patients. The skin cells (fibroblasts, the cells that produce the structural protein collagen) experienced a decrease in damaging ...

Complexes of methylene blue with DNA are characterized by time- resolved fluorescence spectroscopy and transient photobleaching methods. At least four, and probably five, spectroscopically distinct binding sites have been identified. Three of these (components 1, 2, and 3B) dominate the fluorescence decay at low ionic strength and have fluorescence lifetimes significantly different from that of the free dye. With increasing ionic strength a fourth component (3A) appears at the expense of components 1 and 3B. Component 3A exhibits two subcomponents with different degrees of shielding from O2 quenching of its triplet state. The relative amplitudes of the components at low ionic strength are strongly dependent on the composition of the DNA, and independent of superhelix density. Hence, it is inferred that components 1, 2, and 3B represent binding to different base pair steps, and that all of these components represent intercalation sites that unwind the DNA to the same degree. Component 3A is ...
With the ever-increasing aging population, neurodegenerative diseases such as Alzheimers disease are becoming more prevalent. Owing to such increases in age related cognitive decline, the need for research into new, effective treatments is more imperative now than ever. The zebrafish is an excellent animal model that can be used to study the potential pharmacological effects of novel cognition-centric treatments. However, more needs to be known about the species and its ability to learn, remember, and the effects certain drugs have on behavior. In this dissertation, I aimed to better understand zebrafish cognition through the testing of three conditions: a known cognitive enhancer (methylene blue; MB), a known inhibitor of memory (scopolamine), and beaker stress, a novel paradigm that will further our understanding of stress on cognitive tasks. Three learning tasks (T-maze, object recognition, and escape learning) were used to elucidate the effects the three conditions had on various types of learning

Bill Melchior asks for a safer method for staining DNA bands in agarose gel, as an experimental protocol for high school teaching. We in Singapore have been doing Biotechnology Workshops for School Teachers to help them device practicals for the school curriculum for the past two years. As far as staining agarose gels is concerned, we have been showing the teachers ethidium bromide staining and UV illumination. Now that you have mentioned the safety hazards involved especially with school pupils, perhaps, I should look into exploring alternatives. One safer alternative, according to Berger and Kimmel, Meths Enzymol Vol 152. or Guide to Molecular Cloning Techniques, Academic Press, 1987 page 71. is methylene blue dye as you suggested. It avoids EthBr and UV. 1.Stain in 0.02% methylene blue, 10mM Tris Acetate pH 8.3 for 1-2 h 4 deg C 2.Wash off excess stain with several changes of water over 5-8 h. 3. Limit of detectability is quoted at 250ng/1 cm band. A colleague says it works fine, other than ...

We propose that the cellular senescence delay caused by MB is due to cycling between MB and MBH2 in mitochondria, which may partly explain the increase in specific mitochondrial activities. Cycling of MB between oxidized and reduced forms may block oxidant production by mitochondria. Mitochondrial dysfunction and oxidative stress are thought to be key aberrations that lead to cellular senescence and aging. MB may be useful to delay mitochondrial dysfunction with aging and the decrease in complex IV in Alzheimer disease ...
Dear Richard, there are a plethora of Special stains, each with their own preferred attributes according to the Technican concerned. The simplest of these is would be either a polychrome methylene Blue or Toluidine Blue or even Thionin , only requiring an application of seconds. The intent here being merely to demonstrate the organsims quickly with a minimum of background staining, and the organisms are best seen in the crypts and morphology is important so background must be low. The next ease of order, would be any of the Romanowsky type stains, the easiest being Leishmans or Wrights and both can be successfullly adapted and only require staining times in the vicinity of 5 and 8 minutes resp. If May Grunwald Giemsa is used (Or Jenner Giemsa) staining times of about 40-60minutes are required, but can be as long as overnight (With very dilute solutions as used by Pinkus for counterstaining Elastin). Other methods include the use of Alcian Yellow and Methylene blue to give blue organisms ...
