Crystalline metal-organic frameworks of divalent transition metal terephthalate belong to a new kind of high-capacity lithium storage materials. In this paper, CoCl2 aqueous solution and CoCl2·6H2O particles are comparatively used as starting materials to react with aqueous lithium terephthalat...

Metal organic frameworks have attracted considerable interest as electrode materials for lithium ion batteries. In this paper, the metal organic frameworks hydrated calcium terephthalate (CaC8H4O4·3H2O) and anhydrous calcium terephthalate (CaC8H4O4) as anodes for lithium ion batteries are compa...

This study examined the catalytic co-pyrolysis of yellow poplar wood and polyethylene terephthalate over basic calcium oxide and acid zeolites, such as HY (SiO2/Al2O3: 30), Hβ (25), HZSM-5 (23), to maximize the yields of aromatics using thermogravimetric analysis and tandem μ-reactor-gas chrom...

Titration of State 4 rat-liver mitochondria at pH 7.2 with the uncoupler 3,5-di-tert-butyl-4-hydroxybenzylidenemalononitrile (SF 6847) at various concentrations of mitochondria and using various substrates indicates that under optimal conditions less than 0.2 molecule of 3,5-di-tert-butyl-4-hydr...

Publisher SummaryLipid peroxidation and ozonation produce oxidized lipids that are bioactive and can act as signal transducers. The synthesis and isolation of these oxidized lipid products in pure form will allow the testing of hypotheses regarding their role as potential relay molecules. Of spe...

Bis(1-hydroxyheptyl)peroxide (BisC7) upon spontaneous hydrolysis affords the difficult-to-isolate ozonation product 1-hydroxy-1-hydroperoxyheptane along with heptanal. PLA2 hydrolytic activity is enhanced when the BisC7 hydrolysis products are incorporated in the membrane of 1-palmitoyl-2-oleoyl...

UDP-N-acetylmuramyl-pentapeptide (UDP-MurNAc-pentapeptide) is well known to be a key intermediate of bacterial peptidoglycan biosynthesis. We first detected the occurrence of UDP-MurNAc-pentapeptide in the cyanobacterium Anabaena cylindrica (NIES-19), and identified the structure of this pentape...

UDP-N-acetylmuramic acid (UDP-MurNAc) is a precursor for peptidoglycan biosynthesis in bacteria. A major difficulty in the study of this pathway is that UDP-MurNAc is not commercially available. We have developed an enzymatic synthesis scheme for UDP-MurNAc using two easily purified Escherichia ...

The effect of the ionization in the RP-HPLC retention of 66 acid-base compounds, most of them drugs of pharmaceutical interest, is studied. The retention time of the compounds can be related to the pH measured in the mobile phase (pwsH) through the sigmoidal equations derived from distribution o...

The interplay of salicylic acid (SA) and reactive oxygen species (ROS) can modulate biotic and abiotic stress of plants, essential biological aerobic oxidation processes. Meanwhile, ROS plays a critical role in TiO2 photocatalytic system for the degradation of organic species. Herein, we develop...

In the preceding paper it was shown that the 266 nm photodissociation of HN3 gives rise to NH fragments exclusively in the vibrationless a(1Δ) state with about 900 cm−1 of rotational energy. These fragments collisionally react with HN3 to produce NH2(2A1) in a chemiluminescent reaction. The tim...

A number of organic corrosion inhibitors of zinc were tested in a 1N HCl medium by the weight loss method. The tafel cathodic slopes relating to solutions containing conventional compounds are 120 mV per current density decade, whereas the solution containing tetraphenylphosphonium bromide gives...

S-Acetamidomethyl (Acm) cysteine was found to be converted quantitatively to cystine by deprotection of the Acm group with silver trifluoromethanesulfonate (AgOTf) followed by dimethylsulfoxide (DMSO) / aqueous hydrochloric acid (HCl) treatment. No significant side reactions were observed with o...

Amiloride HCl is available in two polymorphic dihydrate forms, either of which can be dehydrated to an anhydrous crystalline form. The anhydrate rapidly rehydrates to polymorph A of the dihydrate upon exposure to ambient relative humidity. The polymorph A and polymorph B dihydrates have similar ...

7-Lithio-3-tert-butylpyrazolo[5,1-c][1,2,4]triazines have been generated for the first time using one-pot nucleophilic addition and metal-halogen exchange reactions in 7-bromopyrazolo[5,1-c][1,2,4]triazines. It was found that the stability of 7-lithio species depends highly on the substitution p...

Failure of the herbicide carbetamide to adequately control annual grasses upon repeated annual application was linked to rapid degradation of this herbicide in soil. Rapid carbetamide degradation in soil was clearly evident following application at normal field rates and when evaluated at time i...

This paper reports on the adsorption of low polarity pesticides Carbetamide and Metamitron on hydrotalcite [Mg3Al(OH)8]2CO3·nH2O and organohydrotalcites [Mg3Al(OH)8]2DDS·nH2O with different degree of dodecyl sulphate (DDS) saturation. The adsorbents and the adsorption products were characteriz...

Herein, we described the design and synthesis of a series of pyridazine-3-carboxamides to be CB2-selective agonists via a combination of scaffold hopping and bioisosterism strategies. The compounds were subjected to assessment of their potential activities through calcium mobilization assays. Am...

AA-induced cell death mechanisms acting on human monocytes and monocyte-derived macrophages (MDM), U937 promonocytes and PMA-differentiated U937 cells were studied. Arachidonic acid induced apoptosis and necrosis in monocytes and U937 cells but only apoptosis in MDM and U937D cells. AA increased...

The clinical applications of anticancer drugs are restricted due to the incomplete delivery to the cancerous tissue and the numerous drug resistance mechanisms involved in malignant cells. In this regard, stimuli-responsive nanomaterials offer a promising prospect to deal with these concerns. In...
