BACKGROUND: The number of patients presenting with sudden onset and persistant anosmia other olfactory disorders, which is a finding related to coronavirus disease has been increased considerably. In this study, we aimed evaluate the efficacy training in persistent after Covid-19 infection.
 METHODS: Forty-six who applied for loss smell infection still had disorders were included study. Od...

Gas chromatography is considered to be the reference method for ethyl alcohol determination. However, enzymatic ethanol assays have been developed for use in the clinical laboratory by several commercial vendors. Essentially, these assays utilize the oxidation of ethyl alcohol to acetaldehyde with concurrent reduction of nicotinamide adenine dinucleotide (NAD) to NADH while monitoring the incre...

In the title compound, C(22)H(18)F(6)N(2)O(2), the five atoms comprising each O=C-C=C-N fragment are almost coplanar (the r.m.s. deviation for the fitted atoms being 0.008 and 0.002 Å) and form a dihedral angle of 47.70 (12)°. The phenyl ring attached to each of the O=C-C=C-N fragments is twisted out of the respective plane with dihedral angles of 64.46 (11) and 61.82 (10)°, respectively. An al...

Environ. Entomol. 27(3): 688-694 (1998) ABSTRACT In field trapping tests, phenyl alkyl amines and phenyl alkyl alcohols with 2-carbon side chains attracted significantly more adult females of the northern com rootworm, Diabrotica barberi Smith & Lawrence, than did phenyl alkyl amines or phenyl alkyl alcohols with 1-, 3-, or 4-carbon side chains. Both sexes ofnorthern com rootworm were attracted...

3-Methyl-1-phenylpyrazol-5-one and its derivatives prepared using ethyl acetoacetate, phenyl hydrazine and its derivatives. Ethyl acetoacetate reacted with phenylhydrazine at reflux temperature to give 3-methyl-1-phenylpyrazol-5-one crude and recrystlized from diluted ethanol to give pure 3-methyl1-phenylpyrazol-5-one. Different pyrazolone derivatives were prepared by using different phenyl hyd...

A novel compound, ethyl 7-methyl-1-(4-nitrophenyl)-5-phenyl-3-(thiophen-2-yl)-1,5dihydro[1,2,4]triazolo[4,3-a]pyrimidine-6-carboxylate (7) was synthesized by reaction of N-(4nitrophenyl)thiophene-2-carbohydrazonoyl chloride (1) with ethyl 6-methyl-4-phenyl-2-thioxo1,2,3,4-tetrahydropyrimidine-5-carboxylate (2). The mechanism of the studied reaction is discussed and the assigned structure was co...

In the title mol-ecule, C23H22N2OS, the di-phenyl-acetyl and ethyl-benzene groups adopt a trans-cis conformation, respectively, with respect to the S atom across the (S=)C-N bonds. This conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond and a weak C-H⋯S hydrogen bond. The ethyl-substituted benzene ring forms dihedral angles of 87.53 (15) and 73.94 (15)° with the phenyl rings. ...
