In this paper, we study uptake and release properties of phenazopyridine hydrochloride (denoted PHP) from [Zn2(NH2-BDC)2(4-bpdh)]·3DMF (denoted TMU-16-NH2) in comparison with [Zn2(BDC)2(4-bpdh)]·3DMF (denoted TMU-16). TMU-16-NH2 can absorb PHP faster than TMU-16 as evidenced from the faster de...
Objective–To describe a rare, but potential clinical manifestation of phenazopyridine (PAP) toxicity in a dog. Case Summary–A 6‐year‐old spayed female Chihuahua was evaluated for ataxia and dysphagia after ingestion of 200 mg (66 mg/kg) of PAP hydrochloride. The dog was presented to the hosp...
Poly[bis(resorcinol monobenzoate)phosphazenes] (PRMBP) and poly[bis(resorcinol monoben- zoate diethylamino)phosphazenes] (PRMBDEAP) were synthesized in two steps. In the first step, polydichlorophosphazenes (PDCP) were synthesized from hexachlorocyclotriphosphazenes (HCCP) via ring opening polym...
By applying nonequilibrium Green's function formalism combined with first-principles density functional theory, we investigate the electronic transport properties of a 1,3-diphenyltriazene-based optical molecular switch. The molecule that comprises the switch can convert between the cis and the ...
The optimized molecular structures of cis and trans conformers of 1,3-diphenyltriazene (DPT) molecule have been calculated using ab initio Hartree–Fock (HF), density functional theory (B3LYP) and second order Müller–Pleaset (MP2) methods with 6–311++G(d,p) basis set level. The trans conforme...
Directeur Dekker van Equipe Zorgbedrijven vraagt zorgverzekeraars meer oog te hebben voor de zelfstandige klinieken gezien het patiëntenbelang en de mogelijkheden voor kostenbeheersing. Hij heeft aangekondigd de verzekeraars dringende vragen te stellen op de Dag van de Zorgverzekeraars.
We study semileptonic decays of the scalar tetraquark $$Z_{bc;\overline{u} \overline{d}}^{0}$$ Zbc;u¯d¯0 to final states $$T_{bs;\overline{u}\overline{d} }^{-}e^{+}\nu _{e}$$ Tbs;u¯d¯-e+νe and $$T_{bs;\overline{u}\overline{d}}^{-}\mu ^{+}\nu _{\mu }$$ Tbs;u¯d¯-μ+νμ , which run throu...
Wireless Regional Access Network (WRAN) is increasingly becoming the focus architecture for future rural and remote areas access network. In Zimbabwe, internet connectivity to the rural areas is crucial but is hindered by what is called the Zimbabwean problem. In this paper brief discussions of ...
The reaction of oxythiamine chloride hydrochloride (HOxTCl·HCl) with ZnCl 2 , CdCl 2 and HgCl 2 in ethanol yielded the complexes [ZnCl 3 (HOxT)], [CdCl 3 (HOxT)] and [HgCl 3 (HOxT)]. In water, the reaction with CdCl 2 afforded [CdCl 2 ...
The influence of pressure and temperature on the catalytic behaviour of H-beta zeolites in the conversion of sec-butylbenzene, an hydrocarbon present in reformed gasoline, has been investigated. The reaction pathway involves many parallel and/or successive steps, the main reactions being dealkyl...
The phase equilibria for the ternary system: dodecane+sec-butylbenzene+N,N-dimethylformamide (DMF) was studied over a temperature range of 288–318K and at atmospheric pressure. Such a system is found in the extraction of aromatics in the middle distillate production. The system studied exhibits...
The obtained results show that styrene dimers, which are the primary transition products of PS cracking undergo consecutive reactions over acid centers of high acid strength (SiO2–Al2O3(45 %); −10.8 −3.3) at sufficiently high reaction temperatures (723–773 K). It is proposed that phenylbuteny...
Tigloyl-CoA:pseudotropine acyl transferase esterifies the 3β-hydroxyl group of pseudotropine (3β-hydroxytropane) with the tiglic acid moiety of tigloyl-Coenzyme A. This enzyme was purified to near electrophoretic homogeneity--about 330-fold--from transformed root cultures of Datura stramonium...
The influence of surface carbon on the formation of highly regular thin films of p-quaterphenyl (4P) grown on a Au(111) surface has been investigated in the mono- and multilayer regime by thermal desorption spectroscopy (TDS), X-ray photoelectron spectroscopy (XPS) and micro-channelplate low ene...
The variably oriented crystallite surfaces of a recrystallized polycrystalline gold sample served as substrates for the investigation of the structure dependence of p-quaterphenyl (4P) thin film growth. The films were prepared in ultrahigh vacuum by organic molecular beam evaporation. Optical mi...
Para-quaterpheny1 (p-4pheny1) thin films were deposited by the thermal evaporation method on glass/quartz substrates for structural and optical investigations. The XRD of p-4phenyl thin films showed that the as-deposited films have a monoclinic structure. The surface morphology of p-4phenyl thin...
Herein two conjugated donor molecules, TDPP‐POCN and FDPP‐POCN, with planar diketopyrrolopyrrole (DPP) as the core building‐block acceptor unit and phenoxazine‐capped acrylonitriles as arms are designed and synthesized. Solution‐processed bulk‐heterojunction organic solar cells based on bl...
The synthesis of some new thiophenyl‐derivatized and furanyl‐derivatized phenothiazine and phenoxazine dyestuffs is described. This was achieved by two methods after the synthesis of 6‐chloro‐5H‐benzo[a]phenothiazin‐5‐one, 6‐chloro‐5H‐benzo[a]phenoxazin‐5‐one, and 6‐chloro‐5H‐naph...
Chloro‐substituted phenothiazines and phenoxazines were successfully derivatized with phenylboronic and styrylboronic acids using Suzuki–Miyaura cross‐coupling reaction catalyzed by Pd(0)/XPhos for the first time in good yields. The protocol employed 4 mol% Pd and 7 mol% XPhos with K3PO4 in a...
Background Protein tyrosine phosphatases (PTPs) like dual specificity phosphatase 5 (DUSP5) and protein tyrosine phosphatase 1B (PTP1B) are drug targets for diseases that include cancer, diabetes, and vascular disorders such as hemangiomas. The PTPs are also known to be notoriously difficult tar...
