The four first generations of dendrigraft poly-L-lysine have been studied in dimethylformamide (aprotic solvent) and in 0.2 M NaCl aqueous solutions by isothermal translation diffusion, 1H NMR and viscometry methods. The relationships between diffusion coefficient, intrinsic viscosity and molar mass have been determined for dendrigraft poly-L-lysines, and the scaling index values have been compared to classical trifunctional dendrimers. Dendrimers and dendrigraft poly-L-lysines exhibited similitudes in their hydrodynamic behaviors. Nevertheless, dendrigraft poly-L-lysines displayed a specific behavior in solution. In contrast to dendrimers, a significant change of hydrodynamic dimension of dendrigraft poly-L-lysines according to the nature of the solvent has been observed. In aprotic solvent, the dendrigraft poly-L-lysine dimensions are about two times lower than in aqueous media (i.e., the hydrodynamic volume is contracted by a factor 8 in dimethylformamide), revealing the softness of dendrigraft poly

Reaction of Organic Halogen Compounds with Metals (Part Ⅰ) A Formation of Organometallic Complex in Dimethyl Formamide Solvent Reaction of organic chlorine containing ester, alcohol, and acids with metallic tin and zinc in dimethyl formamide solvent gave a good yield of organo metallic complex. The same reaction under a mixed U.V. irradiation could not give an appreciable yield of the complex except in the case of an elevated reaction temperature. The solvation effect of dimethyl formamide of the metallic complex formation was markedetly increased as compared to the reaction in toluene and cyclohexane. In case of chlorine containing carboxylic acid, the formation of organo chloro zinc complex of the salt was observed. The reaction of organo zinc complex with a carbonyl precursor gave the addition product together with a dimerized product. Especially the aldehyde species enhanced the formation of zinc complex. The addition reaction was simple and convenient, but the yield was not high.(30-40% for

Solvation interactions and ion association in solutions of LiClO4 in N,N-dimethylformamide (DMF) have been studied by using infrared spectra, Raman spectra, and NMR spectra for the nuclei 7Li, 13C, 14N, 17O, and 35Cl. The behavior of the OCN deformation vibration, the 13C NMR, and the 17O signal of the carbonyl support the proposition that solvation is through the carbonyl oxygen. A quantitative study of the OCN deformation vibrational band in the Raman spectra yielded a solvation number of 3.6 for the Li+ ion with an indication that severe crowding and solvent-solvent interactions exist for the solvated cation. The solvation interactions are particularly strong and ion association is not significant below 2 M salt concentration. Above this concentration, evidence for both solvent-shared and contact ion pairs has been obtained. Consistent evidence from the perchlorate stretching vibrational band in the Raman spectra and 35Cl, 7Li, and 17O NMR supported a set of sequential equilibria (Li+)s + ...

After the ...

A modified calix[4]pyrrole, namely meso-tetramethyl-tetrakis-(4-hydroxyphenyl) calix[4]pyrrole, 1, has been synthesized and characterized. (1)H NMR investigations in various deuterated solvents seems to indicate that this receptor interacts with acetone-d(6). The solution thermodynamics of 1 in various solvents is reported. Complexation studies in CD(3)CN show that the NH and OH functionalities of 1 are the active sites of its interaction with the fluoride and the dihydrogen phosphate anions. The composition of the anion complexes was established through conductance measurements. In all cases, 1:1 complexes are formed. The thermodynamics of anion complexation in acetonitrile and N,N-dimethylformamide is discussed comparatively with previous reported data for the parent calix[4]pyrrole, 2, and these anions in these solvents. The medium effect on anion complexation is discussed in terms of the solvation properties of the reactants and the product in acetonitrile and N,N-dimethylformamide. An oligomeric

Poly(ε-caprolactone) (PCL) fibers ranging from 250 to 700 nm in diameter were produced by electrospinning a polymer tetrahydrofuran/N,N-dimethylformamide solution. The mechanical properties of the fibrous scaffolds and individual fibers were measured by different methods. The Youngs moduli of the scaffolds were determined using macro-tensile testing equipment, whereas single fibers were mechanically tested using a nanoscale three-point bending method, based on atomic force microscopy and force spectroscopy analyses. The modulus obtained by tensile-testing eight different fiber scaffolds was 3.8 ± 0.8 MPa. Assuming that PCL fibers can be described by the bending model of isotropic materials, a Youngs modulus of 3.7 ± 0.7 GPa was ...

0034] The polar pharmaceutical agent of the method at 100 can be mixed with a polar solvent suitable to dissolve the polar pharmaceutical agent and produce a coating solution (110). A suitable polar solvent includes any known or hereafter discovered polar solvent. Polar solvents generally include molecules having an unequal sharing of electrons among the atoms of the molecules (e.g., asymmetrically or unevenly distributed electrons), such that there is a net charge on the molecules or a portion of the molecules. Generally, polar solvents have a dielectric constant of greater than 5. Polar solvents that can be used with the methods disclosed herein include, but are not limited to, one or more aprotic solvents, including dichloromethane (DCM), tetrahydrofuran (THF), ethyl acetate, acetone, dimethylformamide (DMF), acetonitrile (MeCN), dimethyl sulfoxide (DMSO), methyl ethyl ketone (MEK) and propylene carbonate, and combinations or derivatives thereof. Polar solvents that can be used with the ...

The apparent molar heat capacities, ϕ C p , of ethanol, n-propanol, n-butanol, and tetraethylammonium, tetra-n-propylammonium, tetra-n-butylammonium and tetra-n-pentylammonium bromides have been measured measured using a Picker flow calorimeter (Sodev, Canada, Model CP-Cpr) at 298.15 K in water-N,N-dimethylformamide (DMF) mixtures. The contribution of the CH2 moiety, ϕ C p (CH2), was estimated from these data as the change in ϕ C p per additional CH2 unit. The values of ϕ C p (CH2) in water (ca. 100 J·K−1·mol−1) are two to three times those in neat organic solvents (ca. 30-40 J·K−1·mol−1), consistent with a substantial contribution from hydrophobic solvation in water. In water-rich aqueous DMF solutions, ϕ C p (CH2) decreases monotonically with increasing DMF concentration, the decrease being more rapid for the n-alcohols. This trend differs significantly from that reported in the literature for highly aqueous mixtures of t-butanol, where ϕ C p (CH2) passes through a ...

Using ionspray tandem mass spectrometry the glutathione conjugate SMG was identified as a biliary metabolite of DMF in rats (0.003% of a dose of 5OOmg/kg DMF i.p.). Formation of this metabolite was increased five fold after induction of CYP2E1 by acetone, and was inhibited to 20% of control values following pretreatment with disulfrram. Generation of SMG from DMF in vivo was shown to exhibit a large kinetic deuterium isotope effect (KWKD=10.1 ± 1.3), which most likely represents the product of 2 discrete isotope effects on N-demethylation and formyl oxidation reactions.The industrial solvent N,N-dimethylformamide (DMF) and the investigational anti-tumour agent N-methylformamide (NMF) cause liver damage in rodents and humans. The hepatotoxicity of N-alkylformamides is linked to their metabolism to N-alkylcarbamic acid thioesters. The enzymatic details of this pathway were investigated. Hepatocytes isolated from BALB/c mice which had been pretreated with acetone, an inducer of the cytochrome ...

Abstract : N,N-Dimethylformamide (DMF) is a universal solvent and has wide variety of applications in organic synthesis,purification, crystallization, and as cross-linking agent. The aim of this study was to evaluate the physicochemical andspectroscopic properties of DMF after the biofield energy treatment using various analytical techniques. DMF sample wasdivided into two parts, one part (control) remained as untreated, while the other (treated) part was treated with Mr. Trivedisbiofield energy treatment. The treated sample was subdivided into three parts named as T1, T2, and T3 for gaschromatography-mass spectrometry (GC-MS) analysis. Five relatively intense peaks were observed in the mass spectrum of bothcontrol and treated samples of DMF. The GC-MS data revealed that the isotopic abundance ratio of (PM+1)/PM in DMF wasslightly decreased by 5.76% in T1, and increased by 48.73%, and 30.17% in T2, and T3 samples, respectively as compared to thecontrol [where, PM- primary molecule, (PM+1)- ...

Data on density, ρ, speed of sound, c, and refractive index, nD, have been reported at (293-303.15) K for the N,N-dimethylacetamide (DMA) + CH3CO(CH2)u − 1CH3 (u = 1, 2, 3) systems, and at 298.15 K for the mixture with u = 5. These data have been used to compute excess molar volumes, VmE, excess adiabatic compressibilities, κSE, and excess speeds of sound cE. Negative VmE values indicate the existence of structural effects and interactions between unlike molecules. From molar excess enthalpies, HmE, available in the literature for N,N-dimethylformamide (DMF), or N-methylpyrrolidone (NMP) + n-alkanone systems, it is shown: (i) amide-ketone interactions are stronger in DMF systems than in those with NMP; (ii) they become weaker when u increases in mixtures with a given amide. Structural effects largely contribute toHmE and are more relevant in mixtures containing NMP. The application of the Florys model reveals that the random mixing hypothesis is valid in large extent for DMF solutions, ...

The interaction of calix[3]thieno[1]pyrrole, 1, and halide and dihydrogen phosphate anions in a variety of solvents (acetonitrile, propylene carbonate, N,N-dimethylformamide, and dimethyl sulfoxide) has been investigated through 1H NMR, conductance measurements, and titration calorimetry. 1H NMR measurements reveal the sites of interaction of the ligand with the anions in CD3CN while the composition of the complex was determined through conductance measurements. A quantitative assessment of anion-ligand interactions is provided. Thus the thermodynamics of complexation of 1 with halide and dihydrogen phosphate anions in dipolar aprotic media at 298.15 K is reported. These data are interpreted in terms of the thermodynamics of transfer of reactants and product from a reference solvent (acetonitrile) to other solvents. The crucial role played by the solvent on the ability of the ligand to interact with anions and on the composition of the complex is demonstrated.. ...

Graft copolymerization of starch has been carried out onto preirradiated polypropylene (PP) in an aqueous medium using benzoyl peroxide (BPO) as the radical initiator. The maximum percentage of grafting (115%) of starch onto PP was obtained at optimum conditions of BPO concentration, 1.239 × 10−3 moles; temperature, 65°C; in 120 min. using 30 mL of water. Swelling studies were carried out in pure, binary, ternary and quaternary solvent systems comprising of water, ethanol (EtOH), dimethylsulphoxide (DMSO), and N,N-dimethylformamide (DMF) in different ratios. Maximum swelling is observed in DMSO and DMF, followed by EtOH and least in water for true graft. Water retention studies of pristine PP and PP-g-Starch (both composite and true graft) were investigated at different time periods, temperature and pH. The composite contains grafted PP, unreacted starch and unreacted PP whereas true graft is the product from which both unreacted polymers have been removed. Maximum % water retention of ...

In this paper, the formation of hydroxypropyl-β-cyclodextrin (HPCD) nanofibers in electrospinning and the adsorption of organic molecules on the HPCD nanofiber were studied. The properties of a polymer-like solution from the highly concentrated HPCD/N,N-dimethylformamide (DMF) solution revealed HPCD supramolecular aggregates formation. The entanglements of HPCD self-organized aggregates were one of the most important factors that significantly influenced fiber formation during cyclodextrin electrospinning. The HPCD self-organized aggregates entanglement concentration (C(e)) was investigated. Analyzing the dependence of specific viscosity (η(sp)) on concentration enabled the determination of the aggregates unentangled and entangled regimes for HPCD polymer-like solutions. The dynamic light scattering (DLS) measurements and the (1)H NMR spectra of the HPCD solutions confirmed the presence of considerable HPCD self-organized aggregates in high concentrated HPCD/DMF solutions due to the intermolecular

CPP (5[6]-carboxyfluorescein-RRRRRR-COOH) synthesis was performed on a 1-mmol scale on preloaded Fmoc-Nw-(2,2,4,6,7-pentamethyldihydrobenzofuran-5-sulfonyl)-L-arginine Wang resin (Sigma-Aldrich, Poole, UK) (loading rate 0.62 mmol g−1) using standard Fmoc-amino acid solid-state peptide synthesis protocols. The initial Fmoc group was removed by deprotection with 20% piperidine in N,N-dimethylformamide (DMF) (3 × 20 minutes), followed by coupling with Fmoc-Nw-(2,2,4,6,7-pentamethyldihydrobenzofuran-5-sulfonyl)-L-arginine in the presence of O-(6-chlorobenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HCTU), N,N-diisopropylethylamine (DIPEA), and DMF in a 1:5:5:10 molar ratio. The reaction was agitated at room temperature for 8 hours, and some of the resin was tested for reaction completion using the ninhydrin test following standard protocols.25 The coupling and deprotection steps were repeated until the peptide sequence reached a total of six arginine residues. The final ...

The solvation of carbanions in the solvents N,N-dimethylformamide (DMF) and tetrahydrofuran (THF) has been analyzed on the basis of experimental and theoretical data. Experimental solvation energies are obtained from present and previously reported electrochemical measurements of reduction potentials of the corresponding radicals. Theoretical solvation energies are obtained from quantum chemical calculations using the polarizable continuum model (PCM). It is found that the solvation energy is relatively independent of molecular size and structure for the saturated carbanions. This indicates that the negative charge is strongly localized to the anionic carbon. The conjugated carbanions have considerably lower absolute solvation energies (\ DeltaG degrees (sol)\) than the saturated carbanions. This is a consequence of the strong delocalization of the negative charge in the former group. The propargyl anion is also found to have a surprisingly low absolute solvation energy. However, high-level ...

DPD simulations were employed to study the phase behavior of paclitaxel loaded PEO11-b-PLLA9 in water and N,N-Dimethylformamide. Different ordered structures were observed in water-rich solvents. All the structures were greatly affected by solvents compositions. By varying the fractions of each component, a phase diagram of paclitaxel loaded PEO11-b-PLLA9 in water and DMF was mapped. For all ordered structures, bicontinuous, lamella, rod, and spherical structures with different sizes could be easily observed for their wide distribution in the phase diagram. While the HPL, dumbbell, and spherical structures with uniform size were difficult to be obtained, due to their narrow distribution. © 2009 Elsevier B.V. All rights reserved ...

The SHV-1 β-lactamase gene was sub-cloned into the pBC SK(-) vector (Stratagene, LaJolla, CA) from a clinical strain of K. pneumoniae (15571), and transformed into E. coli DH10B cells (Invitrogen, Carlsbad, CA) [15]. The K. pneumoniae clinical isolate possessed the SHV-5 ESBL and was obtained from a previous study [16]. E. coli DH10B without the blaSHV-1 gene served as a negative control.. The procedures used to isolate, express and purify the SHV-1 β-lactamase and to produce the anti-SHV β-lactamase antibodies have been previously detailed [13]. Purified anti-SHV antibodies were fluorescein-labeled with the EZ-Label™ fluorescent labeling kit (Pierce, Rockford, IL), according to the instructions of the manufacturer. In brief, 1 mg of polyclonal anti-SHV antibodies in 1 ml phosphate buffered saline (PBS, 2 mM monobasic sodium phosphate, 8 mM dibasic sodium phosphate, 154 mM sodium chloride, pH 7.4) was mixed with 7.6 μl of a 10 mg/ml solution of NHS-fluorescein in N, N-dimethylformamide for ...

Tritopic pyridinebis(hydrazone)-based ligands typically produce square M(9) [3 × 3] grid complexes with first-row transition-metal ions (e.g., M = Mn, Fe, Co, Cu, Zn), but with larger lanthanide ions, such coordination motifs are not produced, and instead linear trinuclear complexes appear to be a preferred option. The reaction of 2pomp [derived from pyridine-2,6-bis(hydrazone) and 2-acetylpyridine] with La(III), Gd(III), and Dy(III) salts produces helical linear trinuclear [Ln(3)(2pomp)(2)]-based complexes, where each metal ion occupies one of the three tridentate ligand pockets. Two ligands encompass the three metal ions, and internal connections between metal ions occur through μ-O(hydrazone) bridges. Coligands include benzoate, nitrate, and N,N-dimethylformamide. The linear Dy(III)(3) complex exhibits single-molecule magnet behavior, demonstrated through alternating-current susceptibility measurements. Slow thermal magnetic relaxation was detected in an external field of 1800 Oe, where quantum

The objective of this research was to improve the fire-retardant properties of wood in one treatment using a phosphorus pentoxide-amine system. Phosphorus pentoxide and 16 amines including alkyl, halophenyl, and phenyl amines were compounded in N,N-dimethylformamide and the resulting solutions containing phosphoramides were reacted with wood. The characteristics of phosphoramide-reacted wood were analyzed by FTIR, energy-dispersive X-ray analysis, and elemental analysis. Fire retardancy of phosphoramide-reacted woods was evaluated by DSC and thermogravimetric analysis (TGA). DSC demonstrated that the modification can lower the onset of an endotherm and decrease the heat of combustion and heat flow. TGA showed that most of the phosphoramide-reacted woods had higher char yields than that of wood impregnated with diammonium phosphate. ...

Polycarbonate polyurethane (PCPU) has been studied as a novel polymer impregnated with nanoparticles for improved mechanical, thermal and adhesion properties [4]. This study investigates the synthesis of polycarbonate polyurethane (PCPU) polymeric nanofiber membranes by the process of electrospinning. This study further examines all the parameters associated with electrospinning a novel PCPU polymeric solution impregnated with nanofillers, such as nanoparticles, to produce fiber membranes. Tetrahydrofuran (THF) and N, N dimethylformamide (DMF) are used as solvents to dissolve PCPU polymer. One percent (1%) of nanofillers like silver and silica nanoparticles are added to PCPU polymer solution to investigate the impact on polymer solution properties, which in turn affects the fiber formation. Process parameters are studied by evaluating the impact each parameter has on the fiber formation. PCPU polymer concentrations of three polymer solutions (PCPU, PCPU + 1% silver and PCPU + 1% silica) with the

Non-aqueous capillary electrophoresis was evaluated for the separation of five hydrophobic basic blue dyes for application in forensic dye analysis. The use of a red light emitting diode as a high intensity, low-noise light source provided sensitive detection of the blue dyes while also allowing the evaluation of solvents that absorb strongly in the UV region. Excellent peak shapes and separation selectivity were obtained in methanol, ethanol, acetonitrile and dimethylsulfoxide, however water, tetrahydrofuran, dimethylformamide and acetone were unsuitable as solvents due to poor peak shapes and a lack of sensitivity, most likely due to adsorption onto the capillary wall. Due to the known compatibility of methanol with capillary electrophoresis-mass spectrometry, this solvent was examined further with the relative acidity/basicity of the electrolyte being optimised with an artificial neural network. The optimised method was examined for the separation of ink samples from 6 fibre tip and 2 ball ...

A comparison of the cytidine 5′-diphosphate (CDP) and adenosine 5′-diphosphate (ADP) reductase activities from Ehrlich tumor cells was made to determine if the properties of the enzyme for these substrates were the same, except for the allosteric effector. It was observed that various purification steps did not result in an enzyme fraction that had a constant ratio of CDP:ADP reductase activities. The optimal Mg2+ ion concentration for CDP reduction was 3 to 4 mm, while the optimal Mg2+ ion concentration for ADP reduction was 0.1 mm. Concentrations of Mg2+ ions greater than 0.1 mm inhibited ADP reduction. CDP reduction was relatively insensitive to the presence of dimethylformamide or dimethyl sulfoxide in the reaction mixture, but ADP reduction was decreased in the presence of these two compounds. Periodate-oxidized adenosine 5′-monophosphate, on incubation with the enzyme, had a greater effect on CDP reduction but little or no effect on ADP reduction. The response of the CDP and ADP ...

Romix, the solubility of normal sodium terephthalate is about 14g of salt per 100ml of saturated solution or about 15g of salt per 100ml of water based on my own experience and this is almost independant of temperature ie you cant recrystallise the sodium salt from water by simply cooling a hot saturated solution. Other sodium salts, particularly NaOH, greatly reduce its solubility so the salt can be precipitated by adding 60% NaOH solution until the concntration of NaOH in the terephthalate solution is about 15% but beware! The resulting slurry is impossible to filter with paper filters and is very fine grained and so washes through all but the finest glass frits. Both bases of terephthalic acid are stronger than carbonic acid and so CO2 will not precipitate terephthalic acid. Terephthalic acid is almost insoluble in water (about 10 milligrams per litre!), the only workable solvent for terephthalic acid appears to be dimethylformamide, solubility 7g per 100ml of solvent at room temperature ...

Abstract: We have developed a new standardized method for the post-embedding immunoelectron microscopy using the same fixation, antigen retrieval and image contrasting procedures. Tissues were fixed with 4% formaldehyde containing 2.5 mM CaCl2, 1.25 mM MgCl2 in a 0.1 M 4-(2-hydroxyethyl)-piperazineethanesulfonic acid (HEPES) buffer (pH 7.4) for 2 h and then with the same fixative composition in 0.1 M HEPES buffer (pH 8.5) overnight at room temperature. Vehicle osmolarity of fixatives was adjusted to 300-330 mOsm by adding glucose. The specimens were dehydrated with dimethylformamide on ice and embedded in LR-White resin. Ultrathin sections were heated in a 20 mM Tris-HCl buffer (pH 9.0) for 1-2 h at 95°C. After immuno-gold labeling, the sections were treated with 2% glutaraldehyde containing 0.05% tannic acid in a 0.1 M phosphate buffer (pH 5.5) for 5 min and with a 1% OsO4/0.1 M phosphate buffer (pH 7.4) for 5 min, and then they were double stained with uranyl acetate and lead citrate.

Acetylene is not especially toxic, but when generated from calcium carbide, it can contain toxic impurities such as traces of phosphine and arsine, which give it a distinct garlic-like smell. It is also highly flammable, as are most light hydrocarbons, hence its use in welding. Its most singular hazard is associated with its intrinsic instability, especially when it is pressurized: under certain conditions acetylene can react in an exothermic addition-type reaction to form a number of products, typically benzene and/or vinylacetylene, possibly in addition to carbon and hydrogen.[citation needed] Consequently, acetylene, if initiated by intense heat or a shockwave, can decompose explosively if the absolute pressure of the gas exceeds about 200 kilopascals (29 psi). Most regulators and pressure gauges on equipment report gauge pressure, and the safe limit for acetylene therefore is 101 kPagage, or 15 psig.[42][43] It is therefore supplied and stored dissolved in acetone or dimethylformamide ...

Poly(2-hydroxyethyl methacrylate) (PHEMA) hydrogels are widely used as biomaterials. Due to their unique combination ofbiocompatibility and good mechanical properties, they have potential as scaf-folds for tissue engineering applications. To this purpose, topographic and chemical patterning at the nano-to the mesoscale is crucial in order to favor and to characterize cell adhesion and proliferation. Here we report the characterization ofas-prepared and patterned PHEMA hydrogels, produced by conventional radical polymerization in water and dimethylformamide. We have obtained chemical and morphological micro- and nanoscale patterning by atomic force microscopy based lithography. We also demonstrate that it is possible to incorporate carbon nanoparticles in the hydrogel matrix by supersonic cluster beam deposition ...

Treatment with retinoic acid restored a non-transformed phenotype to this transformed cell line in a dose dependent manner. Retinoic acid (RA) treated AKR-MCA cells showed a non-transformed morphology, a slower growth rate, and did not grow with anchorage independence. A 38,000 Da protein was phosphorylated to a high degree in the AKR-MCA transformed cell line compared to the non-transformed AKR-2B cell line. RA treatment greatly reduced the level of phosphorylation of this protein in AKR-MCA cells. Growth arrested AKR-MCA cells showed a mitogenic response to nutrient replenishment, but not to epidermal growth factor (EGF). ...

INTRODUCTION. There are several aspects in the magnetic and spectral behavior of the lanthanides which are different from the d block of the transition metals . The 4ƒelectrons in the orbitals are more shielded respect to the external. For this reason, the stages originated from the several 4ƒn configuration are slightly affected by the media surrounding the ions and remains invariable in particular for all third row compounds1.. The spin-orbital coupling constant is extremely large. As a consequence, but with some exceptions, the lanthanide ions possess fundamental stages with only one well defined value of the total angular moment J, with the following lowest J value and with several energiesgreaterthan the KT value. Furthermore, the highestζ values are non-populated.. The great number of metallic complexes absorbs visible light and/or UV, but only light emission inthe UV range producing, luminescence. The trivalent lanthanide ions and their complexes are known by their luminescence ...

Most of these protocols use as the mobile phase an aqueous blend of water with a miscible, polar organic solvent, such as acetonitrile or methanol. Expert Answer Methanol is a polar molecule: See graphic on the left. Yes. Similarly, the polarity of a molecule is directly proportional to the dipole moment. In contrast, Oxygen forms one sigma bond but has two lone pairs, so there is a bent in its bond angle due to bonded pair-lone pair repulsion forces.

Hindu religion has bestowed Tulsi, with the status of mother. Also known as Sacred or Holy Basil, Tulsi, has been recognized as a religious and spiritual devout in many parts of the world. The vedic sages knew the benefits of Tulsi and that is why they personified it as a Goddess and gave a clear message to the entire community that it needs to be taken care of by the people, literate or illiterate. We try to protect it because it is like Sanjeevani for the mankind. Tulsi has great medicinal properties. It is a remarkable antibiotic. Taking Tulsi everyday in tea or otherwise increases immunity and help the drinker prevent diseases, stabilize his or her health condition, balance his or her body system and most important of all, prolong his or her life. Keeping Tulsi plant at home prevents insects and mosquitoes from entering the house. It is said that snakes do not dare to go near a Tulsi plant. Maybe that is why ancient people would grow lots of Tulsi near their houses ...

Jackrabbit @237. Funny, Ive been re-looking at the Biden & Harris exchange and also been coming to the view that might well have been a set-up; was Biden angry or was he just biting his lip?

The connections between Harris and Clinton are well-known long before the debate, Kamala harris has long been regarded as Clintons candidate. I appreciate that you may only have learnt about this recently. I would suggest that you didnt because you were more focused on disparaging Tulsi Gabbard and as a result gave a free-ride to a deeply entrenched establishment candidate.. IMO Tulsi Gabbard is a far better candidate than even Sanders and a vote for her would definitely be a protest against the establishment and a clear message about ending the regime change wars..
