Fungal metabolism of acenaphthene by Cunninghamella elegans. (1/26)

The filamentous fungus Cunninghamella elegans ATCC 36112 metabolized within 72 h of incubation approximately 64% of the [1,8-14C]acenaphthene added. The radioactive metabolites were extracted with ethyl acetate and separated by thin-layer chromatography and reversed-phase high-performance liquid chromatography. Seven metabolites were identified by 1H nuclear magnetic resonance, UV, and mass spectral techniques as 6-hydroxyacenaphthenone (24.8%), 1,2-acenaphthenedione (19.9%), trans-1,2-dihydroxyacenaphthene (10.3%), 1,5-dihydroxyacenaphthene (2.7%), 1-acenaphthenol (2.4%), 1-acenaphthenone (2.1%), and cis-1,2-dihydroxyacenaphthene (1.8%). Parallel experiments with rat liver microsomes indicated that the major metabolite formed from acenaphthene by rat liver microsomes was 1-acenaphthenone. The fungal metabolism of acenaphthene was similar to bacterial and mammalian metabolism, since the primary site of enzymatic attack was on the two carbons of the five-member ring.  (+info)

occupational exposure to aromatic hydrocarbons at a coke plant: Part II. Exposure assessment of volatile organic compounds. (2/26)

The objective of the study is to assess the external and internal exposures to aromatic hydrocarbons in the tar and oil naphthalene distillation processes at a coke plant. 69 workers engaged as operators in tar and oil naphthalene distillation processes and 25 non-exposed subjects were examined. Personal analyses of the benzene, toluene, xylene isomers, ethylbenzene, naphthalene, indan, indene and acenaphthene in the breathing zone air allowed us to determine the time weighted average exposure levels to the aromatic hydrocarbons listed above. The internal exposure was investigated by measurement of the urinary excretion of naphthols, 2-methylphenol and dimethylphenol isomers by means of gas chromatography with a flame ionization detection (GC/FID). Urine metabolites were extracted after enzymatic hydrolysis by solid-phase extraction with styrene-divinylbenzene resin. The time-weighted average concentrations of the hydrocarbons detected in the breathing zone air shows that the exposure levels of the workers are relatively low in comparison to the exposure limits. Statistically significant differences between average concentrations of aromatic hydrocarbons (benzene, toluene, xylene isomers) determined at the workplaces in the tar distillation department have been found. Concentrations of the naphthalene and acenaphthene detected in workers from the oil distillation department are higher that those from the tar distillation department. Concentrations of naphthols, 2-methoxyphenol and dimethylphenol isomers in the urine of occupationally exposed workers were significantly higher than those of non-exposed subjects. Concentrations of the 2-methoxyphenol and dimethylphenol isomers in urine were significantly higher for the tar distillation workers, whereas concentrations of naphthols were higher for the oil naphthalene distillation workers. Operators at the tar and naphthalene oil distillation processes are simultaneously exposed to a mixture of different hydrocarbons, mainly benzene and naphthalene homologues.  (+info)

Nonphotic entrainment of the circadian body temperature rhythm by the selective ORL1 receptor agonist W-212393 in rats. (3/26)

We synthesized a small-molecule opioid receptor-like 1 (ORL1) receptor agonist, 2-{3-[1-((1R)-acenaphthen-1-yl)piperidin-4-yl]-2,3-dihydro-2-oxo-benzimidazol-1-y l}-N-methylacetamide (W-212393), and investigated its effect on the circadian body temperature rhythm of rats. W-212393 has high affinity for ORL1 receptors in the rat cerebral cortex and human ORL1 receptors expressed in HEK293 cells with K(i) values of 0.76 and 0.50 nM, respectively. W-212393 concentration-dependently stimulated GTPgamma(35)S binding and its efficacy was similar to nociceptin/orphanin FQ (N/OFQ), suggesting that W-212393 is a full agonist at ORL1 receptors. W-212393 dose-dependently occupied ORL1 receptors following intraventricular or intraperitoneal administration, suggesting that W-212393 is a brain-penetrating compound. W-212393 (100 nM) and N/OFQ (100 nM) significantly suppressed the activity of spontaneously firing rat suprachiasmatic nucleus neurons. These suppressive effects were blocked by an ORL1 receptor antagonist, J-113397 (1 microM). W-212393 (3 mg kg(-1), i.p.) induced a significant phase advance at circadian time 6 (CT6) and CT9, but not at other CTs. The magnitude of the W-212393 (0.3-3 mg kg(-1), i.p.)-induced phase advance was dose-dependent and greater than those produced by 8-hydroxy-2-(di-n-propylamino)tetralin (0.3-3 mg kg(-1), i.p.) or melatonin (0.3-3 mg kg(-1), i.p.). The W-212393 (3 mg kg(-1), i.p.)-induced phase advance was antagonized by J-113397 (10 mg kg(-1), i.p.).W-212393 (3 mg kg(-1), i.p.) significantly accelerated the re-entrainment of the body temperature rhythm to a 6 h advanced light-dark cycle. These results indicate that activation of ORL1 receptors contributes to the circadian entrainment and W-212393 may represent an interesting agent for the study of circadian rhythms.  (+info)

Evolution of a strategy for the synthesis of structurally complex batzelladine alkaloids. Enantioselective total synthesis of the proposed structure of batzelladine F and structural revision. (4/26)

Stereoselective synthesis of octahydro-5,6,6a-triazaacenaphthalenes 29 and 34 having the anti-relationship of the angular hydrogens flanking the pyrrolidine nitrogen confirmed suspicions that the relative configuration of the left-hand tricyclic guanidine fragment of batzelladine F should be revised to have the syn relationship of these hydrogens. Several strategies were examined for coupling tricyclic guanidine fragments to prepare potential structures for batzelladine F. Eventually, a convergent synthesis strategy was devised, whose central step was a fragment-coupling tethered-Biginelli reaction (Scheme 17). Using this approach we synthesized four potential structures of batzelladine F, 35-38. None of these compounds, nor their enantiomers, were identical to natural batzelladine F. Reinvestigation of mass spectra of natural batzelladine F, and fragments 88 and 89 obtained upon saponification of batzelladine F, demonstrated that the originally proposed connectivity of this alkaloid was also incorrect. The revised connectivity, 90, of natural batzelladine F depicted in Scheme 21 is proposed.  (+info)

Functional and transcriptional analyses of the initial oxygenase genes for acenaphthene degradation from Sphingomonas sp. strain A4. (5/26)

Sphingomonas sp. strain A4 is capable of utilizing acenaphthene as its sole carbon and energy source. To isolate the genes responsible for acenaphthene degradation, transposon mutagenesis was performed on strain A4 and four mini-Tn5-inserted mutants lacking the ability to utilize acenaphthene were isolated. In three of the four mini-Tn5 inserted mutants, the mini-Tn5s were inserted into the same locus (within about 16 kb) as the arhA1A2 genes, which had previously been identified as the genes encoding the terminal oxygenase components for the initial oxygenation of acenaphthene. The nucleotide sequence analysis of the corresponding 16.4 kb DNA fragment revealed the existence of 16 ORFs and a partial ORF. From these ORFs, the genes encoding the ferredoxin (ArhA3) and ferredoxin reductase (ArhA4) complementary to ArhA1A2 were identified. RT-PCR analysis suggested that a 13.5 kb gene cluster, consisting of 13 ORFs and including all the arhA genes, forms an operon, although it includes several ORFs that are apparently unnecessary for acenaphthene degradation. Furthermore, using gene disruption and quantitative RT-PCR analyses, the LysR-type activator, ArhR, required for expression of the 13.5 kb gene cluster was also identified. Transcription of the gene cluster by ArhR was induced in the presence of acenaphthene (or its metabolite), and a putative binding site (T-N11-A motif) for ArhR was found upstream from the transcription start point of arhA3.  (+info)

Novel intermediates of acenaphthylene degradation by Rhizobium sp. strain CU-A1: evidence for naphthalene-1,8-dicarboxylic acid metabolism. (6/26)

The acenaphthylene-degrading bacterium Rhizobium sp. strain CU-A1 was isolated from petroleum-contaminated soil in Thailand. This strain was able to degrade 600 mg/liter acenaphthylene completely within three days. To elucidate the pathway for degradation of acenaphthylene, strain CU-A1 was mutagenized by transposon Tn5 in order to obtain mutant strains deficient in acenaphthylene degradation. Metabolites produced from Tn5-induced mutant strains B1, B5, and A53 were purified by thin-layer chromatography and silica gel column chromatography and characterized by mass spectrometry. The results suggested that this strain cleaved the fused five-membered ring of acenaphthylene to form naphthalene-1,8-dicarboxylic acid via acenaphthenequinone. One carboxyl group of naphthalene-1,8-dicarboxylic acid was removed to form 1-naphthoic acid which was transformed into salicylic acid before metabolization to gentisic acid. This work is the first report of complete acenaphthylene degradation by a bacterial strain.  (+info)

An environmental quinoid polycyclic aromatic hydrocarbon, acenaphthenequinone, modulates cyclooxygenase-2 expression through reactive oxygen species generation and nuclear factor kappa B activation in A549 cells. (7/26)

Diesel exhaust particles (DEPs) contain oxygen-containing polycyclic aromatic hydrocarbons (PAHs) called quinoid PAHs. Some quinoid PAHs generate free radicals as they undergo enzymatic and nonenzymatic redox cycling with their corresponding semiquinone radicals. Reactive oxygen species (ROS) produced by these reactions can cause severe oxidative stress connected with inflammatory processing. Although humans and animals are continuously exposed to these chemicals in the environment, little is known about which quinoid PAHs are active. In this study, we estimated the intracellular ROS production and nuclear factor kappa B (NF-kappaB) translocation in A549 cells exposed to isomers of quinoid PAHs having two to four rings. We found that both acenaphthenequinone (AcQ) and 9,10-phenanthrenequinone (PQ) enhanced ROS generation and that AcQ translocated NF-kappaB from the cytosol to the nucleus. However, PQ, which has been reported to induce apoptosis, did not influence NF-kappaB activation. In addition, AcQ induced cyclooxygenase-2 (COX-2) expression which is a key enzyme in the inflammatory processing involved in the activation of NF-kappaB. Upregulation of NF-kappaB and COX-2 expression by AcQ treatment was suppressed by the antioxidant N-acetylcysteine (NAC). These results provide that AcQ might play an important role in human lung inflammatory diseases as an air pollutant.  (+info)

High-affinity CRF1 receptor antagonist NBI-34041: preclinical and clinical data suggest safety and efficacy in attenuating elevated stress response. (8/26)

There is an extensive evidence that corticotropin releasing factor (CRF) is hypersecreted in depression and anxiety, and blockade of CRF could have therapeutic benefit. We report preclinical data and the results of a clinical Phase I study with the novel nonpeptide CRF(1) antagonist NBI-34041/SB723620. Preclinical data conducted with different cell lines expressing human CRF receptors and in Wistar and Sprague-Dawley rats indicate that NBI-34041 is effective in reducing endocrine responses to pharmacological and behavioral challenge mediated by CRF(1) receptors. These specific properties and its well-documented safety profile enabled a clinical Phase I study with 24 healthy male subjects receiving NBI-34041 (10, 50, or 100 mg) or placebo for 14 days. Regulation of the hypothalamic-pituitary-adrenocortical (HPA) axis was evaluated by intravenous stimulation with 100 microg of human CRF. Psychosocial stress response was investigated with the Trier Social Stress Test (TSST). Treatment with NBI-34041 did not impair diurnal adrenocorticotropic hormone (ACTH) and cortisol secretion or CRF evoked ACTH and cortisol responses but attenuated the neuroendocrine response to psychosocial stress. These results suggest that NBI-34041 is safe and does not impair basal regulation of the HPA system but improves resistance against psychosocial stress. NBI-34041 demonstrates that inhibition of the CRF system is a promising target for drug development against depression and anxiety disorders.  (+info)

Persistently hyperphosphorylated Akt contributes to human oncogenesis and resistance to therapy. Triciribine (TCN) phosphate (TCN-P), the active metabolite of the Akt phosphorylation inhibitor TCN, is in clinical trials, but the mechanism by which TCN-P inhibits Akt phosphorylation is unknown. Here we show that in vitro, TCN-P inhibits neither Akt activity nor the phosphorylation of Akt S473 and T308 by mammalian target of rapamycin or phosphoinositide-dependent kinase 1. However, in intact cells, TCN inhibits EGF-stimulated Akt recruitment to the plasma membrane and phosphorylation of Akt. Surface plasmon resonance shows that TCN, but not TCN, binds Akt-derived pleckstrin homology (PH) domain (K(D) 690 nM). Furthermore, nuclear magnetic resonance spectroscopy shows that TCN-P, but not TCN, binds to the PH domain in the vicinity of the PIP3-binding pocket. Finally, constitutively active Akt mutants, Akt1-T308D/S473D and myr-Akt1, but not the transforming mutant Akt1-E17K, are resistant to TCN ...
Copper bis(4-ethyl-3-thiosemicarbazonato) acenaphthenequinone (1) and copper bis(4-methyl-3-thiosemicarbazonato) acenaphthenequinone (2) are synthesized and characterized in solution, in the solid state, and radiolabeled. Serum-protein binding radioassays show good stability in solution and about 25 % binding to protein over 1 h, which is comparable with the hypoxia selective tracer [(64)Cu(ATSM)]. Cyclic voltammetry shows fast and reversible reduction at redox potentials similar to the values known for hypoxia-selective copper compounds. However, despite this, complex 1 does not show any hypoxic-selective uptake in HeLa cells over 1-h standard assays. Possible reasons for this are studied by using the intrinsic fluorescence of the Cu(II) complexes to determine the cellular distributions and uptake mechanism by confocal microscopy. The complexes are found to bind to the external cell membrane and disperse evenly in the cytoplasm only after a very slow cell internalization (|1 h). No significant changes
D5739-06(2020) Standard Practice for Oil Spill Source Identification by Gas Chromatography and Positive Ion Electron Impact Low Resolution Mass Spectrometry
A noise source identification technique for the analysis of thermal systems is presented. The proposed method uses transient spectral sound data to assist in determining the source of sound radiation by tracking the variation of the frequency of tones during transient thermal loading (i.e., thermal system warm-up). By considering the temperature dependence of the modulus of elasticity (Youngs modulus) it can be shown that structure related tones will decrease in frequency during warm-up. Tones due to propagation of sound in many fluids (i.e., gases and water) will increase in frequency during warm-up due to the temperature dependence of the speed of sound. The analysis method is demonstrated by identifying the source of several noise tones for a pulse combustion furnace ...

The CERES-Maize model was developed to investigate how variations in environmental conditions, management decisions, and genetics interact to affect crop development and growth. A tile drainage subroutine was incorporated into CERES-Maize to improve soil-water and nitrogen leaching under subsurface tile drainage conditions. The purpose of this work was to evaluate the soil-water, soil-nitrogen, tile drainage, and tile-nitrogen loss routines of CERES-Maize for tile-drained fields in Iowa. An analysis was conducted based on information collected from a study of 36 plots consisting of five management systems during a 4-year period from 1993 to 1996, at Nashua, IA. The model was calibrated for each plot using data from 1994 and 1995, and validated using data from 1993 and 1996. Temporal soil-water contents and water flow from tile drains were calibrated to an average root mean square error (RMSE) of 0.036 cm3 cm−3 and 2.62 cm, respectively, compared to measured values. Validation trials gave an ...
The fate of six polynuclear aromatic hydrocarbons during anaerobic digestion of municipal sludges was investigated in a two-stage pilot-scale digester system. Primary digester removal efficiencies ranged from 23% for acenaphthene to 62% for acenaphthylene; secondary digester removal efficiencies ranged from 22% for acenaphthylene to 42% for phenanthrene. Most of the remaining mass of candidate compounds was present in the secondary digester waste sludge stream. Less than 2.5% of the candidate compounds entering the digestion system was present in the secondary digester supernatant. A dynamic model of the primary digester incorporating mixed first-order biodegradation kinetics was calibrated for each of the candidate compounds. The biodegradation rate coefficients that were estimated for the primary digester ranged from 0.004 L/g·d for acenaphthene to 0.16 L/g·d for acenaphthylene. The biodegradation rate coefficient for acenaphthene did not significantly differ from zero ...

Wybutosine (yW) is a tricyclic nucleoside with a large side chain found at the 3-position adjacent to the anticodon of eukaryotic phenylalanine tRNA. yW supports codon recognition by stabilizing codon-anticodon interactions during decoding on the ribosome. To identify genes responsible for yW synthesis from uncharacterized genes of Saccharomyces cerevisiae, we employed a systematic reverse genetic approach combined with mass spectrometry (ribonucleome analysis). Four genes YPL207w, YML005w, YGL050w and YOL141w (named TYW1, TYW2, TYW3 and TYW4, respectively) were essential for yW synthesis. Mass spectrometric analysis of each modification intermediate of yW revealed its sequential biosynthetic pathway. TYW1 is an iron-sulfur (Fe-S) cluster protein responsible for the tricyclic formation. Multistep enzymatic formation of yW from yW-187 could be reconstituted in vitro using recombinant TYW2, TYW3 and TYW4 with S-adenosylmethionine, suggesting that yW synthesis might proceed through sequential ...
The use of methanol as a quenching reagent resulted in clean conversion of 3 to the abnormal adduct aIPr·GaR3 (5) (Scheme 2b). Notably, 5 is also formed as a protonation product from the reaction of 3 with the imidazolium salt IMes·HCl (1,3-bis-(2,4,6-trimethylphenyl)imidazolium chloride) (Scheme 2c). These findings not only demonstrate that the C2 position of 3 in the imidazole ring is its preferred basic site, but also the high strength of its Ga-C4 bond as it is retained in 5. Furthermore in view of these results it appears that for the GaR3 fragment aIPr is a better ligand than the related normal IMes carbene (obtained from deprotonation of the imidazolium salt, Scheme 2c), as no ligand exchange occurs. Compound 5 was isolated as a crystalline solid in a 61% yield (see ESI‡ for experimental details and NMR spectroscopic studies) and its molecular structure was established by X-ray crystallography (Fig. 4).. The Ga-C4 bond length (i.e. Ga-C2 in Fig. 4) of 2.0759(16) Å in 5 is ...
Emission inventory (EI) and receptor model (RM) are two of the three source apportionment (SA) methods recommended by Ministry of Environment of China and used widely to provide independent views on emission source identifications. How to interpret the mixed results they provide, however, were less studied.

By utilizing a highly resolved speciated regional EI and a region-wide gridded volatile organic compounds (VOCs) speciation measurement campaign, we elucidated underlying factors for discrepancies between EI and RM and proposed ways for their interpretations with the aim to achieve a scientifically plausible source identification ...
misc{5098ed88-419a-43f4-a897-5d700385fe0b, abstract = {Aerosol particles have, since Classical Antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution causes 100 000 deaths in Europe each year, whereof 5 000 in Sweden. These figures do not include the outcomes of indoor sources or smoking, which shortens the lives of millions of people worldwide. Many studies indicate that fine particles (<2.5 μm) are to be more toxic than larger ones. Especially the ultrafine particles (<0.1 μm), typically originating from combustion sources, have been of much concern. Part of the reason could be their high probability to deposit deep into the lung once inhaled. A novel method has been developed for determination of fine and ultrafine particle deposition in the respiratory tract. It is designed to be used on larger groups of human subjects in exposure studies and in typical ambient and indoor environments. The method is demonstrated to have a ...

Speaker: Prof. Dr. Ellen Aschermann (Department of Psychology - Cologne University, invited by Prof. Thomas Lachmann) Topic: Children`s source identification - the impact of different interview conditions Abstract: During school age children learn information from different sources. Although the content of the learned information is easily kept, the source of the information is often forgotten. In eyewitness context, the source of an information plays an important role and accuracy of source identification has been a major topic in children`s eyewitness research (cf. Roebers, Moga & Schneider, 2001). In our study (N=105, age 7-11) we investigated the role of accuracy motivation on primary school childrens event recall. The design was a 2 (recognition test: forced vs. withhold) x 2 (punishment: detracting token vs. informational feedback) between-subject design. All children heard two stories about circus visits and were interrogated after seven days about this situation. After a cognitive ...
A notable feature of this and other clone library analyses from G.I. environments is the number of sequences that do not cluster with any known species. Sequences from nonruminant feces fell within the genera Bacteroides and Prevotella, while most sequences from ruminant hosts did not cluster with any known species. Both the range of sequence identity with the closest known species (87 to 91%) and the interclade identity range (81 to 94%) suggest that taxonomic diversity exists among ruminant sequences. Representatives of these groups must be isolated before phenotypic characterization or classification can be determined.. Within the genus Bacteroides, cloned sequences were closely related to known species, reflecting the greater number of cultivated representatives in this genus. This in turn reflects a greater emphasis placed on the study of the human fecal flora relative to other animal hosts. Many cultivated Bacteroides species, particularly B. vulgatus, B. uniformis, B. thetaiotaomicron, ...

Fig. 2 Salinity profile expected to develop after long-term use of water of ECw = 1.0 dS/m at various leaching fractions (LF). For all practical purposes, the added energy required to absorb water from the salty soil (osmotic potential) is additive to the energy required to absorb water from a salt-free soil (soil-water potential). The cumulative effect is illustrated in Figure 3 and results in an important reduction in water available to the crop as salinity increases. Salinity effects are closely analogous to those of drought as both result in water stress and reduced growth. Stunting, leaf damage and necrosis or obvious injury to the plant are only noticeable after prolonged exposure to relatively high salinity.. The previous discussion showed how the concentration of salts in the soil varied with leaching fraction and depth in the root zone and resulted in an increase in concentration as the leaching fraction decreases or with increasing depth in the root zone.

The volume of extracted water from the soil specimen in the volumetric pressure plate can be continuously measured during the test without the stoppage of air pressure during the measurements. However, the water volume measurement in the volumetric pressure plate requires an air trap, a ballast tube, a burette, and a vacuum device while maintaining a constant pore-water pressure in the soil specimen, which is quite complicated and tedious. In order to improve the measuring method of the volumetric pressure plate, a modified volumetric pressure plate was developed and tested on residual soil specimens. The modified apparatus can measure the volume of the extracted water using both Method A and Method B of ASTM D6836-02 depending on the range of matric suction. In addition, the volume of diffused air during testing can also be measured for ...

Recycled concrete aggregate (RCA) is known to be a hydrophilic material. Anattempt has been made to convert RCA into a hydrophobic material by coatingit separately with oil or wax. Both oil and wax are known to increase thehydrophobicity of soil. Although the soil-water characteristic curve (SWCC) andpermeability function of coarse-grained aggregates have been investigated, theeffect of the introduction of hydrophobicity (coating it with oil or wax) into thecoarse aggregates to their SWCC and permeability function has not been fullyunderstood. The SWCC indicates that coating RCA with oil or wax modifies thedrying and wetting curves as compared with RCA without any coating. The air-entry values and water-entry values are also modified upon coating. RCAs coatedwith oil or wax were found to prevent ingress of water during the wetting test forSWCC. The permeability function of RCAs is also modified ...

According to the REACH Regulation, Annex VIII, Column 2, the study does not need to be conducted if based on the physicochemical properties the substance can be expected to have a low potential for adsorption (e.g. the substance has a low octanol water partition coefficient). Direct Blue 199 is expected to have a low potential for absorption, on the basis of the partition coefficient; the log Pow was determined to be negative. The organic carbon-water, suspended matter-water and soil-water partition coefficients were in any case estimated, using EUSES v.2.1.2, in order to derive the PNECs for sediment and soil, according to the equilibrium partitioning method. Furthermore, for the same purpose the soil-water and suspended matter-water partition coefficients were also estimated: Suspended matter-water partition coefficient: 0.917 Soil-water partition coefficient: 0.22 [LogKoc: -0.17] ...
In this study, multi-planar Nearfield Acoustical Holography (NAH) is used to investigate noise radiated from the front, side and rear areas of single tires on a two-wheel trailer. Contributions to the radiated noise from the leading edge, trailing edge, and sidewall of the tire are identified. Two tires - an experimental monopitch tire and a production passenger car tire - are evaluated on a smooth asphalt pavement at 58 km/hr. From the measured complex pressure, acoustic intensity is reconstructed on three planes surrounding the tire using modified NAH procedures. Additionally, sound power levels are presented in tabulated and spectra forms. Tire noise generating mechanisms are inferred based on the results ...

Modulating signaling pathways for research and therapy requires either suppression or expression of selected genes or internalization of proteins such as enzymes, antibodies, nucleotide binding proteins or substrates including nucleoside phosphates and enzyme inhibitors. Peptides, proteins and nucleotides are transported by fusing or conjugating them to cell penetrating peptides or by formation of non-covalent complexes. The latter is often preferred because of easy handling, uptake efficiency and auto-release of cargo into the live cell. In our studies complexes are formed with labeled or readily detectable cargoes for qualitative and quantitative estimation of their internalization. Properties and behavior of adhesion and suspension vertebrate cells as well as the protozoa Leishmania tarentolae are investigated with respect to proteolytic activity, uptake efficiency, intracellular localization and cytotoxicity. Our results show that peptide stability to membrane-bound, secreted or intracellular

Free roaming dogs are increasing in numbers. They live in unhygienic conditions and are not vaccinated mostly. They create several problems in the community, particularly health threats to human. Dog biting is a commonly reported case in some hospitals in Bangladesh. Rabies is one of the killers of people in Bangladesh and transmission occurs mostly due the dog biting. Death commonly occurs in children due to rabies. Rabies death is completely preventable by vaccinating dogs at national level. Many steps have already been taken. Source identification of dogs, animal birth control program and proper surveillance are necessary. Sustainable implementation of programs to manage dog population, dog bite management and awareness raising among population can bring out fruitful result in this situation. Inhumane killing of dogs to reduce the number can never be a permanent solution. Vaccinating dogs is the most effective strategy suggested by experts. Therefore, it is not too late to implement action plans with

Interest in agricultural water management extends beyond irrigation and into catchment management and dryland cropping systems. Collaborative research projects with partners in Africa have focussed on interactions between land-use and hydrological response in a semi-arid environment.. My research often brings together elements of soil science and hydrology within broader interdisciplinary approaches to environmental management. This interest is reflected in recent work, which explored indigenous farmers knowledge of their soils as an aid to planning soil-water management interventions. It is reflected also in a third focus of research, which has involved a succession of research students in investigation of the soil hydrological processes affecting management of salinity in irrigated land.. ...
Shallow rooting and susceptibility to drought are believed to be caused, at least in part, by strongly acidic (pH < 5.5, 1:1 soil-water), aluminum (Al)-toxic subsoils. However, this hypothesis has not been clearly confirmed under field conditions. The Al toxicity hypothesis was tested on a map unit of Matawan-Hammonton loam (0-2% slope) on unlimed and limed field plots (pH range 5.1 to 5.8) at Bel ...

We used the redox-active bis(imino)acenapthene (BIAN) ligand to synthesize homoleptic aluminum, chromium, and gallium complexes of the general formula (BIAN) 3M. The resulting compounds were characterized using X-ray crystallography, NMR, EPR, magnetic susceptibility and cyclic voltammetry measurements and modeled using both DFT and ab initio wavefunction calculations to compare the orbital contributions of main group elements and transition metals in ligand-based redox events. Ultimately, complexes of this type have the potential to improve the energy density and electrolyte stability of grid-scale energy storage technologies, such as redox flow batteries, through thermodynamically-clustered redox events. ...

Phytopathogenic fungi must feed on their hosts to propagate and cause disease. Their ability to access the rich nutrient supply offered by living plants is one of the most obvious properties that distinguish pathogens from saprophytes. Successful invasion by pathogens depends as much on their ability to utilize the available nutrient sources offered by plants as on their ability to penetrate plants and evade defensive mechanisms. Here, we review current knowledge on the nature of the nutrient supplies utilized by pathogens during infection.The available evidence is rudimentary in most cases. There is much evidence to suggest that fungal metabolism can be divided into at least two phases. The first is based on lipolysis and occurs during germination and penetration of the host. The second phase uses glycolysis and predominates during the invasion of host tissue. We also propose, mainly on theoretical grounds, that a third phase of nutrition occurs late in infection during which new spores are ...

BaP's metabolites are mutagenic and highly carcinogenic, and it is listed as a Group 1 carcinogen by the IARC. Chemical agents and related occupations, Volume 10, A review of Human Carcinogens, IARC Monographs, Lyon France 2009 [13] In June 2016, BaP was added as benzo[def]chrysene to the REACH Candidate List of Substances of very high concern for Authorisation.[14] Numerous studies since the 1970s have documented links between BaP and cancers.[15] It has been more difficult to link cancers to specific BaP sources, especially in humans, and difficult to quantify risks posed by various methods of exposure (inhalation or ingestion).[citation needed] A link between vitamin A deficiency and emphysema in smokers was described in 2005 to be due to BaP, which induces vitamin A deficiency in rats.[16] A 1996 study provided molecular evidence linking components in tobacco smoke to lung cancer.
