Transformation of Cinchona alkaloids into 1-N-oxide derivatives by endophytic Xylaria sp isolated from Cinchona pubescens. (1/15)

The microbial transformation of four Cinchona alkaloids (quinine, quinidine, cinchonidine, and cinchonine) by endophytic fungi isolated from Cinchona pubescens was investigated. The endophytic filamentous fungus Xylaria sp. was found to transform the Cinchona alkaloids into their 1-N-oxide derivatives.  (+info)

Screening for antimicrobial activity of ten medicinal plants used in Colombian folkloric medicine: a possible alternative in the treatment of non-nosocomial infections. (2/15)

BACKGROUND: The antimicrobial activity and Minimal Inhibitory Concentration (MIC) of the extracts of Bidens pilosa L., Bixa orellana L., Cecropia peltata L., Cinchona officinalis L., Gliricidia sepium H.B. & K, Jacaranda mimosifolia D.Don, Justicia secunda Vahl., Piper pulchrum C.DC, P. paniculata L. and Spilanthes americana Hieron were evaluated against five bacteria (Staphylococcus aureus, Streptococcus beta hemolitic, Bacillus cereus, Pseudomonas aeruginosa, and Escherichia coli), and one yeast (Candida albicans). These plants are used in Colombian folk medicine to treat infections of microbial origin. METHODS: Plants were collected by farmers and traditional healers. The ethanol, hexane and water extracts were obtained by standard methods. The antimicrobial activity was found by using a modified agar well diffusion method. All microorganisms were obtained from the American Type Culture Collection (ATCC). MIC was determined in the plant extracts that showed some efficacy against the tested microorganisms. Gentamycin sulfate (1.0 microg/ml), clindamycin (0.3 microg/ml) and nystatin (1.0 microg/ml) were used as positive controls. RESULTS: The water extracts of Bidens pilosa L., Jacaranda mimosifolia D.Don, and Piper pulchrum C.DC showed a higher activity against Bacillus cereus and Escherichia coli than gentamycin sulfate. Similarly, the ethanol extracts of all species were active against Staphylococcus aureus except for Justicia secunda. Furthermore, Bixa orellana L, Justicia secunda Vahl. and Piper pulchrum C.DC presented the lowest MICs against Escherichia coli (0.8, 0.6 and 0.6 microg/ml, respectively) compared to gentamycin sulfate (0.9 8 g/ml). Likewise, Justicia secunda and Piper pulchrum C.DC showed an analogous MIC against Candida albicans (0.5 and 0.6 microg/ml, respectively) compared to nystatin (0.6 microg/ml). Bixa orellana L, exhibited a better MIC against Bacillus cereus (0.2 microg/ml) than gentamycin sulfate (0.5 microg/ml). CONCLUSION: This in vitro study corroborated the antimicrobial activity of the selected plants used in folkloric medicine. All these plants were effective against three or more of the pathogenic microorganisms. However, they were ineffective against Streptococcus beta hemolytic and Pseudomonas aeruginosa. Their medicinal use in infections associated with these two species is not recommended. This study also showed that Bixa orellana L, Justicia secunda Vahl. and Piper pulchrum C.DC could be potential sources of new antimicrobial agents.  (+info)

Polymer-supported Cinchona alkaloid-derived ammonium salts as recoverable phase-transfer catalysts for the asymmetric synthesis of alpha-amino acids. (3/15)

Alkaloids such as cinchonidine, quinine and N-methylephedrine have been N-alkylated using polymeric benzyl halides or co-polymerized and then N-alkylated, thus affording a series of polymer-supported chiral ammonium salts which have been employed as phase-transfer catalysts in the asymmetric benzylation of an N-(diphenylmethylene)glycine ester. These new polymeric catalysts can be easily recovered by simple filtration after the reaction and reused. The best ee's were achieved when Merrifield resin-anchored cinchonidinium ammonium salts were employed.  (+info)

Cinchona alkaloids are also produced by an endophytic filamentous fungus living in cinchona plant. (4/15)

We report that the endophytic filamentous fungus Diaporthe sp., isolated from Cinchona ledgeriana and cultivated in a synthetic liquid medium, produces Cinchona alkaloids (quinine, quinidine, cinchonidine, and cinchonine). This shows that Cinchona alkaloids are produced not only in Cinchona plant cells, but also in endophytic microbe cells.  (+info)

Integration efficiency in DNA-induced transformation of Pneumococcus. I. A method of transformation in solid medium and its use for isolation of transformation-deficient and recombination-modified mutants. (7/15)

A method of transformation on solid medium especially adapted for pneumococcus has been developed. Under specific conditions, all colonies that are allowed to grow in the presence of transforming DNA for six hours give rise to transformed bacteria. Combined with replica plating this technique has been used to isolate mutants modified with regard to recombination. Most of the mutants found are transformation-defective and show a large diversity in their response to ultraviolet light. Some of these mutants have lost their ability to take up transforming DNA. One shows a reduced yield of transformants for a given quantity of DNA taken up. Mutants that manifest altered behavior with regard to marker efficiencies have also been isolated. One of these exhibits a decrease in the transformation efficiency of only the high efficiency markers and two mutants show a decrease in the transformation efficiency of the low efficiency markers.  (+info)

Integration efficiency in DNA-induced transformation of Pneumococcus. II. Genetic studies of mutant integrating all the markers with a high efficiency. (8/15)

Transformation of the pneumococcus mutant 401 by DNA's bearing the standard reference marker and several other markers belonging to two unlinked loci has shown that differences in the integration efficiencies of these markers were considerably reduced in this strain compared to the wild-type strain Cl(3). The sensitivities of mutant 401 to ultraviolet light and to X-ray irradiation are the same as those of Cl(3). However, in 401 all the markers tested are more resistant to inactivation as shown by transformation of 401 and Cl(3) by ultraviolet-irradiated DNA. The increase in resistance is greater for low efficiency (LE) markers than for high efficiency (HE) markers.-The decreased discrimination between LE and HE markers in strain 401 is not due to a mechanism related to modification of markers in the transforming DNA by the recipient cells, nor are the proteins inducing competence of the cells responsible for the differences in the integration efficiencies of various markers.-Genetic studies of the fate of recombinants as well as the measure of the amount of DNA taken up have shown that all the markers are integrated in strain 401 by the same recombination process, that specific to high efficiency markers.  (+info)

We have established a robust and versatile analytical platform for probing membrane protein function in a defined lipid environment on solid supports. This approach is based on vesicle capturing onto an ultrathin poly(ethylene glycol) (PEG) polymer brush functionalized with fatty acid moieties and subsequent vesicle fusion into a contiguous membrane. In order to ensure efficient formation of these tethered polymer-supported membranes (PSM), very small unilamellar vesicles (VSUV) containing fluorescent lipids or model transmembrane proteins were generated by detergent depletion with cyclodextrin. Thus, very rapid reconstitution of membrane proteins into PSM was possible in a format compatible with microfluidics. Moreover, surfaces could be regenerated with detergent solution and reused multiple times. Lipid and protein diffusion in these membranes was investigated by fluorescence recovery after photobleaching, single molecule tracking, and fluorescence correlation spectroscopy.

However, there are not just genes in these yarns. So called "regulatory genomic elements," that can control the activity of neighboring genes like switches are also found clustered together with the genes in these chromosomal yarns. A group of genes belonging to the same yarn will therefore be likely to contact a similar set of regulatory elements, and this can result in the coordinated activity of these genes during development.. These new observations shed some light on several long-standing mysteries of genetics, such as the reason why some DNA mutations can end up affecting genes that are located thousands or even a million base pairs away. "The cell nucleus is packed with genes, and the cell is faced with the challenge to turn on or off each one of them correctly," said Dekker. "By organizing groups of genes in isolated domains, or yarns that do not mingle or mix with other genes, the cell has solved the problem of how to regulate groups of genes coordinately and without interference from ...
Many ideas embedded in PCS have been widely used across various areas of data science. Predictability plays a central role in science through Popperian falsifiability (4). If a model does not accurately predict new observations, it can be rejected or updated. Predictability has been adopted by the machine-learning community as a goal of its own right and more generally to evaluate the quality of a model or data result (5). While statistics have always considered prediction, machine learning emphasized its importance for empirical rigor. This was in large part powered by computational advances that made it possible to compare models through cross-validation (CV), developed by statisticians Stone (6) and Allen (7).. The role of computation extends beyond prediction, setting limitations on how data can be collected, stored, and analyzed. Computability has played an integral role in computer science tracing back to Alan Turings seminal work on the computability of sequences (8). Analyses of ...

In an attempt to further improve catalyst enantioselectivities, Jew and Park linked two cinchona alkaloid moieties via spacer units. With such a dimeric cinchona alkaloid (06542), enantioselectivity for the above mentioned glycine imine alkylation was optimized to 97-99% ee.1. Nucleophilic catalysts have had a wide-ranging role in the development of new synthetic methods. In particular, the cinchona alkaloids catalyze many useful processes with high enantioselectivities. Cinchona alkaloids can be used as bases to deprotonate substrates with relatively acidic protons forming a contact ion pair between the resulting anion and protonated amine. This interaction leads to a chiral environment around the anion and permits enantioselective reactions with electrophiles.. Important in many of these processes is the ability to control the formation of quaternary asymmetric centers with high enantiomeric excesses. Using the (DHQD)2AQN (456713) catalyst it is possible to affect the α-functionalization of ...
Considerable inter- and intraspecific variation with respect to the quantity and composition of plant natural products exists. The processes that drive this variation remain largely unknown. Understanding which factors determine chemical diversity has the potential to shed light on plant defenses against herbivores and diseases and accelerate drug discovery. For centuries, Cinchona alkaloids were the primary treatment of malaria. Using Cinchona calisaya as a model, we generated genetic profiles of leaf samples from four plastid (trnL-F, matK, rps16 and ndhF) and one nuclear (ITS) DNA regions from twenty-two Cinchona calisaya stands sampled in the Yungas region of La Paz (Bolivia). Climatic and soil parameters were characterized and bark samples were analyzed for content of the four major alkaloids using HPLC-UV to explore the utility of evolutionary history (phylogeny) in determining variation within species of these compounds under natural conditions. A significant phylogenetic signal was found for the

The nucleophilic quinuclidine nitrogen can also be used directly as a reactive center for enantioselective catalysis. Cinchona alkaloids therefore can be used as bases to deprotonate substrates with relatively acidic protons forming a contact ion pair between the resulting anion and protonated amine. This interaction leads to a chiral environment around the anion and permits enantioselective reactions with electrophiles.. Important in many of these processes is the ability to control the formation of quaternary asymmetric centers with high enantiomeric excesses. Using the (DHQD)2AQN (456713) catalyst it is possible to affect the α-functionalization of ketones by the addition of TMSCN to the corresponding cyanohydrin in excellent yield and enantiomeric excess (Scheme 4).6. ...

Quinine was discovered as a cure for Malaria in 1638 when the wife of the Spanish Viceroy in Peru, the Countess of Cinchona, had fallen violently ill with the disease. Her husband begged the local Incas for an antidote. The Incas instructed her to drink a potion containing the ground bark of the native "Quinquina" tree, which grew on the slopes of the Andes. The potion worked and she quickly recovered. In her honour, the Spanish renamed the Peruvian tree the "Cinchona" tree ...

WALL, JOHN (1708-1776), physician, born at Powick, Worcestershire, in 1708, was the son of John Wall, a tradesman of Worcester city. He was educated at Worcester grammar school, matriculated from Worcester College, Oxford, on 23 June 1726, graduated B.A. in 1730, and migrated to Merton College, where he was elected fellow in 1735, and whence he took the degrees of M.A. and M.B. in 1736, and of M.D. in 1759. After taking his M.B. degree he began practice as a physician in Worcester, and there continued till his death. In 1744 he wrote an essay (Philosophical Transactions, No. 474, p. 213) on the use of musk in the treatment of the hiccough, of fevers, and in some other cases of spasm. In 1747 he sent a paper to the Royal Society on the Use of Bark in Smallpox (ib. No. 484, p. 583). When cinchona bark was first used its obvious and immediate effect in malarial fever led to the opinion that it had great and unknown powers, and must be used with extreme caution, and this essay is one of a long ...

Ascocoryne sarcoides is an endophytic filamentous fungus isolated from Northern Patagonia that can produce petroleum-like fuel compounds directly from cellulose (Strobel et al., 2008). The aim of this project was to study volatile organic compound production by A. sarcoides. The project is different from many other cellulosic biofuel projects that explore alcohol production from pre-treated biomass fermentation. It focuses on the ability of A. sarcoides to convert cellulose and related simple sugars to fuel-related hydrocarbons. The influence of environmental conditions on the growth characteristics and compounds produced from normal metabolic processes was explored. Quantification of volatile production from growth on glucose showed the major compounds were ethanol and acetaldehyde, with the remainder of volatiles near 2 ppm from a continuously aerated culture. These volatiles included compounds of fuel-interest such as benzaldehyde, nonanal, 1-octen-3-ol and 1-butanol, 3-methyl-. Notable ...
Download the product note.. Biotage®PS-HOBt(HL) is a sulfonamide-linked, polymer supported equivalent of 1-hydroxybenzotriazole (HOBt). PS-HOBt(HL) is used to generate bound HOBt active esters, which can either be made and used in situ, or isolated and stored as stable intermediates. Treatment of bound HOBt esters with an amine leads to amide formation in generally high purity without the need for further purification.. To date, the recommended procedure for loading PS-HOBt has required PyBroP as the coupling agent. We have developed an improved loading procedure based on the use of diisopropylcarbodiimide and DMAP. The new procedure has proven to be much more reliable, efficient, and cost effective. It requires fewer equivalents of carboxylic acid and does not require a double coupling as is the case when PyBroP is used.. Polymer-supported active esters offer some unique advantages for parallel amide synthesis. The polymer-supported active esters of PS-HOBt(HL) can be prepared using the ...

Northwestern Medicine collaborated with international colleagues in a study that identified two dozen new genes linked to lupus after analyzing genetic samples from over 27,000 individuals across the globe.. The study, published in Nature Communications, was co-authored by Rosalind Ramsey-Goldman, MD, DrPH, the Solovy/Arthritis Research Society Research Professor of Medicine in the Division of Rheumatology, part of a group of authors from more than 70 universities.. "These new observations will help direct future research to better diagnose and treat the disease while also providing insights into why lupus disproportionately affects certain ethnicities at higher rates and more severely," said Ramsey-Goldman, also a member of the Robert H. Lurie Comprehensive Center Cancer and Northwestern University Clinical and Translational Sciences Institute.. Systemic lupus erythematosus (SLE) is an autoimmune disease that predominantly affects women during their childbearing years, and is more common in ...
Abstract: We present new observations of 26 symbiotic and symbiotic-like stars. The photoelectric UBV observations were made during the years 1982-92, the photographic in 1989-92 and visual in 1989-92. The most interesting results can be summarized as follows: EG And: There is an apparent increase in all three colours corresponding to the ascending branch of the secondary minimum. UV Aur: The long-term photoelectric photometry supports our earlier identification of the red giant component as the primary cause of light variations. BF Cyg: UBV data cover well the last active phase of the star with maximum around 1990 July. CH Cyg: The photoelectric data cover the sudden light brightening starting in Feb-Mar 1992 and decline in Sep 1992. CI Cyg: Long-term UBV observations are presented. AG Dra: UBV photometry cover almost all the interval since the last outburst. CQ Dra: The stars brightness has been decreasing monotonically during the present observational period. AX Per: Our UBV data reveal an ...

20 Autoregressive integrated moving average (ARIMA) modelling can improve the revision properties of the seasonally adjusted and trend estimates. ARIMA modelling relies on the characteristics of the series being analysed to project future period data. The projected values are temporary, intermediate values, that are only used internally to improve the estimation of the seasonal factors. The projected data do not affect the original estimates and are discarded at the end of the seasonal adjustment process. The lending finance collections use an individual ARIMA model for the majority of the series in this publication. The concurrent seasonal adjustment approach re-estimates seasonal factors each month with the receipt of each new observation. The parameters used for seasonal adjustment are routinely reviewed every 12 to 24 months to ensure the quality of the seasonal factors. The last reanalysis occurred in February 2017 for the January 2017 issue. For more information on ARIMA modelling see ...

VISIT any health shop and you are likely to see them: packages of homeopathic remedies claiming to cure whatever ails you, from coughs and fever to insomnia and asthma. Flip the package of medicine, however, and you may be confused by the listed ingredients. Some claim to contain crushed bees, stinging nettles and even arsenic, as well as sugars such as lactose and sucrose. Americans alone spend some $3 billion a year on homeopathic medicines. What are they thinking?. The history of homeopathy - literally, "similar suffering" - dates back to the late 18th century. Samuel Hahnemann, a German doctor, was unimpressed by contemporary medicine, with good reason. Doctors used leeches to let blood and hot plasters to bring on blisters, which were then drained. In 1790, Hahnemann developed a fever that transformed his career. After swallowing powder from the bark of a cinchona tree, he saw his body temperature rise. Cinchona bark contains quinine, which was already known to treat malaria. Hahnemann ...

It occurs in the form of colourless, shining, silky crystals, neutral to litmus, without odour, but with a strong, bitter taste. It may contain either three or six molecules of water of crystallisation. Melting-point (of the anhydrous salt), 205°, with darkening. The sulphate should not lose more than 8 per cent. of its weight on drying at 100°. It should only slightly tinge concentrated sulphuric acid. Not more than a slight fluorescence should be noticeable in a solution (1 in 1000) in dilute sulphuric acid (limit of quinine and quinidine). If 5 decigrams be shaken with 20 mils of water at 15° for some time, 5 decigrams of sodium potassium tartrate added, and the mixture left with frequent shaking for an hour, the filtrate should not show more than a faint opalescence on the addition of a drop of solution of ...
This book is a monograph on the treatment of malaria. It has nine chapters and ninety-one pages. Each chapter treats of a distinct phase of the subject and a perusal of the chapter titles given below will give a good idea of the scope of the work. The first impression gained in reading this book is that the author is giving the reader the results of his own personal experience and that although references are frequent the subject matter is true first hand knowledge. Chapter I: Cinchona Febrifuge. This is evidently a proprietary article, considerably used throughout the British dependencies and without legally defined composition. The author pleads for its standardization. Chapter II: The Relative Merits of the different Alkaloids of Cinchona in Malaria.

Quinine is a type of alcohol, first derived from the bark of a cinchona tree in the 19th century. It serve numerous medicinal purposes, like treating cramps and malaria. If used improperly, however, the product can seriously endanger peoples health and can even lead to death in some extreme circumstances.
Cattle will develop a taste for locoweed that can prove fatal; bighorn sheep will grind their teeth to useless nubs scraping a hallucinogenic lichen off ledge rock. Siegel suggests that some of these adventurous animals serves as our Virgils in the garden of psychoactive plants.

Pigeons spacing out on cannabis seeds (a favorite food of many birds) may have tipped off the ancient Chinese (or Aryans or Scythians) to that plants special properties. Peruvian legend has it that the puma discovered quinine: Indians observed that sick cats were often restored to health after eating the bark of the cinchona tree. Tukano Indians in the Amazon noticed that jaguars, not ordinarily herbivorous, would eat the bark of the yaje vine and hallucinate; the Indians who ...
At least 7,000 medical compounds in the Western pharmacopoeia are derived from plants[8]. All plants produce chemical compounds as part of their normal metabolic activities. These can be split into primary metabolites, such as sugars and fats, found in all plants, and secondary metabolites found in a smaller range of plants, some useful ones found only in a particular genus or species.. The autologous functions of secondary metabolites are varied. For example, as toxins to deter predation, or to attract insects for pollination. It is these secondary metabolites which can have therapeutic actions in humans and which can be refined to produce drugs. The word drug itself comes from the Swedish word "druug", which means dried plant. Some examples are inulin from the roots of dahlias, quinine from the cinchona, morphine and codeine from the poppy, and digoxin from the foxglove. The active ingredient in Willow bark, once prescribed by Hippocrates, is salacin, or salicylic acid alpha-hydroxybenzoic ...

In this paper, new CCD photometric observations of V508 Oph obtained in 2009 and 2010 at the Xinglong Observatory are presented. From the new observations, six new times of minimum light were derived. The light curves were analyzed by using the 2003 version of the Wilson-Devinney program. It is found that the asymmetric light curves can be modeled by a hot spot on the secondary component. The degree of overcontact is 15.4%, implying that the system is a shallow-contact binary. Combining the new times of minimum light with the photoelectric and CCD data compiled from the database, we investigate its orbital period. The results show that the orbital period may be undergoing multiple changes: a long-term decrease at a rate of dP/dt=−(1.502±0.063)×10{sup −7} days year{sup −1}, and a small periodic variation with a period of 24.27(±0.34) years. Since V508 Oph is an overcontact system and both components are late-type stars, we discuss the possible connection between the mass transfer, ...
Throughout the development of anatomy as a scientific study, authors have been challenged to give a singular comprehensive definition of what should be considered as a fascial tissue. Instead, the multiplicity of synthesis and analysis is the true richness of scientific research: individual points of view and background look at the fascia from their own perspective, sometimes influenced by their own cultural assumptions. No person or organization in science ever have the absolute truth, because scientific truth is always evolving, driven by new observations and analysis of data. Only by observing the fascia from multiple perspectives (doctor, surgeon, osteopath, physiotherapist, bioengineer and more) can we define more fully what fascial tissue is. It becomes the synergistic result of several scientific disciplines (anatomy, cardiology, angiology, orthopaedics, osteopathy, cytology, and more). The fascia is not the exclusive domain of a few people or individual private associations, but of all
In this study, we developed a novel strategy to discriminate MDMs from MiDMs. We used SBF-SEM to address the detailed relationships of MiDM and MDM to axoglial units in the spinal cords of mice at EAE onset and expression profiling to examine potential mechanisms. Selection of the EAE disease model ensured that both recruited monocytes and resident microglia were exposed to the same intensely inflammatory environment to increase the likelihood that ambient conditions could activate these two myeloid cell types toward a convergent inflammatory phenotype. Instead, we found strikingly divergent relationships of MDMs and MiDMs to axoglial units, by quantitative and qualitative ultrastructural analysis. Results from expression profiling supported this interpretation by showing that MiDM metabolism was severely down-regulated, whereas expression profiles of MDMs reflected the activated phagocytic phenotype observed through SBF-SEM.. Several salient new observations emerged from these experiments. ...
Quite. Homeopaths select these "remedies" according to a principle known as the "Law of Similars", or "Like cures like". In 1790, the German physician Samuel Hahnemann noticed that cinchona bark, which contains quinine and had long been used as a malaria remedy, actually produced some of the symptoms of malaria when taken by a healthy person (namely himself). Unfortunately for homeopaths, it may be that Hahnemanns reaction to the cinchona was in fact simply the result of an undiagnosed allergy. Nevertheless, it led him to wonder if a general principle of similarity could be used to discover new remedies, and to classify the chaotic muddle of herbal and mineral preparations that constituted the materia medica of the day. He therefore embarked on a series of experiments upon himself and others, to test for the pathological effects of various substances, including mercury, belladonna, tobacco and nux vomica. Family, friends, students and colleagues submitted themselves to these "provings", and by ...

If you need to go in for medical treatment that involves the use of quinine or wish to consume products that contain quinine then you should know all about what is quinine. It is certainly important to understand more about this potent drug as well as its side-effects.. Quinine is extracted from the bark of the cinchona tree. The malaria-fighting abilities of this bitter-tasting drug were discovered by the Quechua Indians several centuries ago and its popularity soon reached the shores of Europe, USA, and the rest of the world where malaria was rampant. While quinine was primarily used to treat malaria during the seventeenth century, it was also used to treat arthritis, lupus, as well as leg cramps since it also acted as a muscle relaxant while possessing anti-inflammatory properties too. Quinine was administered orally in the form of quinine sulfate tablets and also delivered in intravenous form to patients including children that had contacted malaria. Adults usually had to consume around 600 ...
Image showing haem binding in cytochrome P450, coordinated by the conserved cysteine and with the quinine substrate in the background.. Quinine. Some human CYPs are able to breakdown quinine by hydroxylation of the molecule to a less toxic form, 3-hydroxyquinine. However, there have also been studies that suggest that quinine can also inhibit the action of certain CYPs. Quinine is used as a treatment for malaria as it is extremely toxic to Plasmodium falciparum, the organism that causes the disease. The mechanism of action is not well understood, however it is thought that it may interfere with the ability of P. falciparum to utilise haemoglobin. It is found in relatively high amounts in the bark of the cinchona tree and is a key ingredient of tonic water. The effectiveness of quinine as a treatment was first documented almost 400 years ago by Jesuit missionaries in South America, with it referred to as Jesuits bark in older documentation. While it is no longer the primary treatment for ...

Antimalarial drugs were first discovered in the seventeenth century [1], two and one-half centuries before the causative agent of malaria was identified. As no other drug before it, quinine, the first antimalarial agent derived from the cinchona tree, helped to shape todays world by enabling explorers and colonists from Europe to survive in tropical countries and to build their colonial empires despite lethal tropical malaria. When physicians were asked to choose the ten most important drugs being used in medicine in 1945, quinine and quinacrine were preceded only by penicillin, sulfonamides and blood derivatives [2]. The antimalarial activity of quinoline antimalarial drugs can be attributed to the interfering with hemoglobin digestion in the blood stages of the malaria parasites life cycle. The parasite degrades the host hemoglobin, in an acidic food vacuole, to generate amino acids for its own protein synthesis, and producing free heme and reactive oxygen species as toxic by-products. The ...

Smith says more bartenders are satisfying this desire by dipping into the little-known well of French aperitif wines known as quinquinas and their Italian counterparts, chinati. While vermouths subtle bitterness traditionally comes from wormwood, quinquinas and chinati acquire their bite from quinine, a substance found in cinchona bark that is also used to flavor tonic water. Along with the distinctive flavor, these wines share with tonic water a history as a pharmaceutical. In 1846, while vying for a government reward for creating a palatable quinine-delivery vehicle, Parisian chemist Joseph Dubonnet introduced the first successful quinquina, flavored with chamomile, green coffee beans, cinnamon and more. When combined with other ingredients in a base of mistelle - partially fermented grape juice mixed with higher-proof alcohol - its character is simultaneously juicy and bone dry.

Arnica 30 helps to slow or stop bleeding after surgery. Phosphorus 30 is the primary remedy for helping to stop bleeding when Arnica does not work adequately. Ipecacuanha 30 is indicated when there is much bleeding of bright red blood, often accompanied by nausea. Secale 30 is effective in treating uterine bleeding that is aggravated by heat and relieved by cold. Cinchona 30 is helpful for people whose bleeding and general loss of fluids lead them to feel weak and faint and have ringing in the ears. This remedy is sometimes indicated several weeks, months, or years after much fluid has been lost, after either an illness or an operation. Arsenicum 30 is useful when profuse bleeding leads to great weakness, burning pains, restlessness, anxiety, and fear, along with a characteristically large thirst for only sips at a time ...
Some six years ago scientific textbooks had to be updated because of the surprising discovery made by the research group led Frank Keppler at the Max Planck Institute for Chemistry that plants produce methane in an oxygen-rich environment. At that time this was unthinkable, since it was commonly accepted that biogenic methane could only be formed during the decomposition of organic material under strictly anoxic conditions. Kepplers group, including Katharina Lenhart, has now made another fascinating new observation: fungi produce methane.
The results of the present study, the largest to investigate this issue to date, show that any independent chronic effect of smoking on BP is small. After adjustment for age, BMI, alcohol, and social class, we found only in older men significantly higher SBPs in heavy and moderate smokers than in never smokers, whereas no such differences were seen for DBP. Therefore, at least in men, our findings do not support those from other studies, which observed lower BPs at increasing levels of cigarette consumption.6 7 The finding of elevated SBP, but not DBP, only in older men is an important new observation that is compatible with effects expected in association with chronically enhanced atherogenesis in large capacitance vessels, with which smoking is associated and which produces isolated systolic hypertension.14 15 In women, we showed lower mean BP levels in light smokers than in nonsmokers and heavier smokers, although the differences reached statistical significance only for DBP in the younger ...
To recognize individual activities in multi-resident environments with pervasive sensors, some researchers have pointed out that finding data associations can contribute to activity recognition and previous methods either need or infer data association when recognizing new multi-resident activities based on new observations from sensors. However, it is often difficult to find out data associations, and available approaches to multi-resident activity recognition degrade when the data association is not given or induced with low accuracy. This paper exploits some simple knowledge of multi-resident activities through defining Combined label and the state set, and proposes a two-stage activity recognition method for multi-resident activity recognition. We define Combined label states at the model building phase with the help of data association, and learn Combined label states at the new activity recognition phase without the help of data association. Our two stages method is embodied in the new activity
This discovery would not have become a revelation for the doctors of Ancient China. Artemisinin used to treat malaria back in the early 70s but the plant on the basis of which manufactured the drug, was used in febrile States already in III-IV centuries.. The residences identified properties of artemisinin, studying traditional Chinese treatises on the use of medicinal herbs. The way this discovery was complicated by a vast array of information, the need to conduct hundreds of experiments and political situation in China of the 70s. fortunately, persistence paid off, and now artemisinin is a key anti-malaria drug.. Artemisinin is not only derived from plants, the compound that is used in modern medicine. For example, another medicine for malaria - quinine comes from the bark of a tropical South American Cinchona tree Cinchona officinalis L. analgesic morphine from the opium poppy Papaver somniferum L, and the poison strychnine - from the tree Strychnos nux-vomica L.

Cyclamen which is similar in many respects, differs from Pulsatilla in dreading the fresh air. Cinchona is the great remedy for anaemia resulting from loss of fluids, as in lactation or haemorrhage, or from all exhausting discharges, such as menstrual flows, long-lasting diarrhoea, and sexual excesses ; but of the latter only those resulting in the loss of semen. The quality of the blood is actually poorer in cases calling for Cinchona. Special symptoms are heaviness of the head, loss of sight, fainting and ringing in the ears, sour belching, poor digestion and bloated abdomen. The patient is sensitive to draughts of air and yet wants to be fanned. Natrum muriaticum is also a remedy for ansemic and debilitated conditions due to loss of fluids, especially in women who suffer from menstrual disorders and in chronic cases with a dead, dirty-looking skin.

TY - JOUR. T1 - Organocatalytic stereoisomerization versus alkene isomerization. T2 - Catalytic asymmetric synthesis of 1-hydroxy-trans -2,5-diphenylphospholane 1-oxide. AU - Hintermann, Lukas. AU - Schmitz, Marco. AU - Maltsev, Olegv. AU - Naumov, Pance. PY - 2013/1/11. Y1 - 2013/1/11. N2 - The potential for an organocatalytic asymmetric stereoisomerization or alkene isomerization as atom-economic reaction with minimal structural change was investigated. The McCormack cycloaddition of 1,4-diarylbuta-1,3-dienes with (dialkylamino)dichlorophosphane and aluminum trichloride gives meso-2,5-diaryl-1-(dialkylamino)-1-oxo-2,5-dihydro-1H-phospholes, which were identified as suitable substrates for asymmetric isomerization to (1R,5R)-2,5-diaryl-1-(dialkylamino)-1-oxo-4,5-dihydro-1H-phospholes in the presence of bifunctional organocatalysts (cinchona alkaloids, Takemoto catalyst) in up to 91% ee and quantitative yield. The substrate range and the mechanism of the catalysis were studied. The reaction ...
In case you or your loved one is afflicted with malaria or certain other diseases or afflictions then you might have to start using quinine tablets for treatment of malaria or for those specific medical conditions. Quinine is in the forefront for fighting malaria in several countries although it has lost favor with the FDA in America.. Quinine is extracted from the bark of the cinchona tree and has been used since well over three centuries to fight malaria. Quinine is known to kill the P.Falciparum parasite that is responsible for spreading malaria into the body and causing death in case of inadequate treatment. There are different methods of administering quinine to patients such as by intravenous drips or injections or in the form of tablets. While quinine is extremely bitter and can easily induce vomiting if administered in its natural form, quinine tablets that contain quinine sulfate with other ingredients to make it palatable can be given to both adults and children. These tablets are ...

The structure of strychnochromine, an unusual alkaloid isolated from a new batch of the root bark of Strychnos gossweileri has been revised . To confirm the indoline structure ( proposed in 1988) and to establish the stereochemistry of the compound extensive 2D-NMR experiments were carried out. The COSY experiments mostly confirmed the previous observations but the COLOC maps did not fit the first proposed structure!The problem was solved by single-crystal X-ray analysis of the p-bromobenzoyl ester of strychnochromine. The new structure, with its tetrahydroquinoline ring, is very unusual in Strychnos species but the formation of quinolines from indole alkaloids has already mentioned in some other plants ( Cinchona, Alstonia, ...
Florence Clyde Chandler was a plant geneticist with a broad background in tree-breeding and the induction of polyploidy (the quality of having one or more extra sets of chromosomes) in flowering plants. Her exceptional success inducing polyploidy in the nuclei by using colchicines resulted in the production of a series of outstanding tetraploid and diploid verbenas. During World War II, she worked at the Guatemalan experimental station as a cinchona (a type of evergreen tree) breeder, where she furthered the successful development of a derivative for quinine, a malaria remedy.. Born on September 28, 1901, in Oliver (Scott County) to William Festus Chandler and Nannie Charlotte Shannon, Florence Chandler was educated at the University of Arkansas (UA) in Fayetteville (Washington County), earning a BA degree in 1923 with a double major in music and science. She began her career teaching biology at Pine Bluff Public Schools from 1923 to 1926. She continued her education while she worked at the New ...
Dr. Joel E. Arem, PhD, FGA has completed a new research paper entitled "Obervations On The Occurrence Of Plagioclase Feldspars (PDF)"; please read this scientifically sound report and make your own conclusions.. As a group, feldspars are the most abundant minerals on planet Earth. Yet despite mineralogical superabundance and gargantuan crystal size, transparent feldspar gems (with a few notable exceptions) are usually tiny and extremely rare. The vast majority of ornamental feldspars are opaque or translucent, white, gray or a very pale hue, and often display a "phenomenon", such as iridescence or some other type of color effect. These materials, including moonstone and sunstone, have been prized as gems for centuries. Several, including labradorite and amazonite, are widely used in jewelry.. Question: what has prevented the gemstone world from paying as much attention to feldspars as they deserve?. Answer: Extreme rarity, small size, and lack of bright coloration has prevented the gemstone ...

Why some individuals develop AIDS rapidly whereas others remain healthy without treatment for many years remains a central question of HIV research. An evolutionary perspective reveals an apparent conflict between two levels of selection on the virus. On the one hand, there is rapid evolution of the virus in the host, and on the other, new observations indicate the existence of virus factors that affect the virulence of infection whose influence persists over years in infected individuals and across transmission events. Here, we review recent evidence that shows that viral genetic factors play a larger role in modulating disease severity than anticipated. We propose conceptual models that reconcile adaptive evolution at both levels of selection. Evolutionary analysis provides new insight into HIV pathogenesis.. ...

Water is being blasted to pieces by a young stars laser-like jets, according to new observations from NASAs Spitzer Space Telescope. The discovery provides a better understanding of how water -- an essential ingredient for life as we know it -- is processed in emerging solar systems.
Whichever model works the best with the closest and more studied celestial groups with the least amount of variable integers would be the best. In other words we should put all our effort into explaining something we can see well enough to discover it all. I get so angry when people throw up, well this theory cant explain this cluster, or this galaxy, or this far flung corner of space we know next to nothing about. We are still discovering massive objects close to home that change our makeup of galaxies. Magnetars are my favorite example, here is a massive object we know very little to nothing about, new observations are placing more and more mass in our universe all the time. Once we have observed enough of these types of bodies, then we can possibly accurately approximate their distribution throughout our galaxy, or others ...
First, do you know the person who takes care of this stray cat, i.e. the cat feeder (caregiver)? If so, you should inform the caregiver first. This is because the cat may already have been taken to the vet and could even be on medication at the moment. Also, the caregiver needs to know that the cat is not well if this is a new observation. If you know the cat caregiver, work in tandem with the caregiver to provide medical attention for the cat. If you dont, or know that there is no fixed caregiver, or that the cat-feeder is not concerned with the health of the cats, then you can proceed to act on your own. Also, if the cat is in severe condition and warrants immediate response, act first and inform the caregiver after ...

Authors: Damadian RV, Chu D.. UPRIGHT Multi-Position MR scanning has uncovered a key set of new observations regarding Multiple Sclerosis (MS), which observations are likely to provide a new understanding of the origin of MS. The new findings may also lead to new forms of treatment for MS. The UPRIGHT MRI has demonstrated pronounced anatomic pathology of the cervical spine in five of the MS patients studied and definitive cervical pathology in the other three. The pathology was the result of prior head and neck trauma. All eight MS patients entered the study on a first come first serve basis without priority, and all but one were found to have a history of serious prior cervical trauma which resulted in significant cervical pathology. The cervical pathology was visualized by UPRIGHT MRI. Upright cerebrospinal fluid (CSF) cinematography and quantitative measurements of CSF velocity, CSF flow and CSF pressure gradients in the upright patient revealed that significant obstructions to CSF flow were ...

Quinidine is a pharmaceutical agent that acts as a class I antiarrhythmic agent (Ia) in the heart. It is a stereoisomer of quinine, originally derived from the bark of the cinchona tree. The drug causes increased action potential duration, as well as a prolonged QT interval. Quinidine is used as a class I antiarrhythmic agent, that is, to prevent ventricular arrhythmias. It is also used to maintain sinus rhythm after cardioversion of atrial fibrillation and to treat short QT syndrome. A combination of dextromethorphan and quinidine has been shown to alleviate symptoms of easy laughing and crying (pseudobulbar affect) in patients with amyotrophic lateral sclerosis and multiple sclerosis. This drug is marketed as Nuedexta in the United States. Intravenous quinidine is also indicated for treatment of Plasmodium falciparum malaria. However, quinidine is not considered the first-line therapy for P. falciparum. The recommended treatments for P. falciparum malaria, according to the Toronto Notes 2008, ...

INTRODUCTION. Mild steel is widely used in chemical industries due to its low cost and easy availability for fabrication reaction of vessel, tanks, pipeline and boiler, because it suffer from severe corrosion in aggressive environments, it has to be protective. The corrosion of metal in aqueous solution occurs in two steps oxidation and reduction. Oxidation reaction takes place at anode, whereas reduction takes place at cathode. The cathodic reaction may be either by evolution of hydrogen and absorption of oxygen.. Mild steel is a reactive metal to reduce the corrosion problem in these environment inhibitive effects of various naturally occurring substance like Datura stramonium1, Tannin beet root, Tamarind, Tealeaves, Pomegranate juice, Saponin2, Embellica officinalis, Terminalia bellerica, a mixture of the later three Spindus trifolianus, Acacia concianna, Swerti aungustifolia and quinoline based cinchona alkaloids as well as very popular ayurvadic powder Mahasudarshana chuma, Prosopis ...
