2,5-Dihexyl-3,6-diphenyl­pyrrolo­[3,4-c]pyrrole-1,4(2H,5H)-dione

The asymmetric unit of the title compound, C30H36N2O2, contains one half-mol­ecule, the other half being generated by a crystallographic inversion centre. The crystal structure is devoid of any classical hydrogen bonds however, non-classical C—H⋯O inter­actions link the mol­ecules into chains propagating in [001] and a C—H⋯π inter­action leads to the formation of a two-dimensional network in (011)

Psychometric properties and cultural adaptation of Polish version of Gynecological Cancers Awareness Scale (GCAS)

Objectives: Cancer of the female genital organs is one of the most common causes of death of women in Poland. The aim of the study was to translate and analyze the psychometric properties of the Polish version of the Gynecological Cancers Awareness Scale (GCAS). Material and methods: Cross-sectional study and questionnaire technic were used to collect data. The study was conducted from June 10th to July10th 2021 among 443 adult women in Poland. Results: The Cronbach Alpha measure was used to assess the internal consistency of the scale. Cronbach’s Alpha values greater than 0.7 indicates that the scale has high reliability. Conclusions: The analysis confirms that the Polish version of Gynecological Cancers Awareness Scale has a very high reliability to assess the women’s cancers awareness and knowledge of cancers

2-(Naphthalen-1-yl)-4-(naphthalen-1-yl­methyl­idene)-1,3-oxazol-5(4H)-one

In the title compound, C24H15NO2, the oxazole ring is oriented at dihedral angles of 10.09 (4) and 6.04 (4)° with respect to the mean planes of the naphthalene ring systems, while the two naphthalene ring systems make a dihedral angle of 4.32 (3)°. Intra­molecular C—H⋯N hydrogen bonds link the oxazole N atom to the naphthalene ring systems. In the crystal, inter­molecular weak C—H⋯O hydrogen bonds link the mol­ecules into centrosymmetric dimers. π–π contacts between the oxazole and naphthalene rings and between the naphthalene ring systems [centroid–centroid distances = 3.5947 (9) and 3.7981 (9) Å] may further stabilize the crystal structure. Three weak C—H⋯π inter­actions also occur

2-(Naphthalen-1-yl)-4-(thio­phen-2-yl­methyl­idene)-1,3-oxazol-5(4H)-one

The asymmetric unit of the title compound, C18H11NO2S, contains two crystallographically independent mol­ecules. In one mol­ecule, the oxazole and thio­phene rings are oriented at dihedral angles of 17.40 (9) and 18.18 (7)° with respect to the naphthalene ring system, while the oxazole and thio­phene rings are oriented to each other at a dihedral angle of 0.86 (9)°. In the other mol­ecule, the corresponding angles are 3.05 (8), 9.62 (6) and 7.02 (8)°, respectively. In each mol­ecule, a weak intra­molecular C—H⋯N hydrogen bond links the oxazole N atom to the naphthalene group. Weak inter­molecular C—H⋯O hydrogen bonding is present in the crystal structure. π–π stacking between the oxazole and thio­phene rings, between the thio­phene and naphthalene rings, and between the oxaozole and naphthalene rings, [centroid–centroid distances = 3.811 (2), 3.889 (2), 3.697 (2) and 3.525 (2) Å] may further stabilize the crystal structure
