Do we miss half of the injuries sustained during rape because we cannot see them? An overview of the use of toluidine blue tissue stain in the medical assessment of rape cases

The prosecution of rape cases is difficult due to the absence of eyewitnesses. McCauley found that the detection of vaginal lacerations increased from one in 24 to 14 in 24 in reported adult rape cases when toluidine blue was used. Proof of injuries consistent with sexual penetration adds significantly to the evidentiary value of the medico-legal testimony. Although rape is not a clinical diagnosis and there are no diagnostic criteria to confirm rape, the possibility of genital injury during rape far exceeds the possibility of injury with consensual intercourse. If a complete examination, including the use of toluidine blue, is not used a rapist may walk away to rape again, while the victims remain with the stigma that they may have made a false allegation.Toluidine blue is a basic thiazine metachromatic dye. It has a high affinity for acidic tissue components, thereby staining tissues rich in DNA and RNA. The epithelium of the external genitalia does not have nucleated cells and prevents contact of stain with nuclei. Where the epithelium is damaged and the underlying nucleated cells are exposed, the nuclei stain blue. Injuries sustained during genital penetration show a distinctive distribution.Toluidine blue stain is easy and safe to use, available, inexpensive and does not interfere with other medico-legal evidence, therefore it is recommended to be used in the examination of all cases of alleged rape.

Novel series of dihydroquinolindihydro-spiro[indoline-3,6 ‘-[1,3]thiazine]-5 ‘-carbonitrile derivatives

A series of new spiro[indoline-3,6’-[1,3]thiazines] were synthesized in modest yields by refluxing of substituted (1,2-dihydroquinolin-3-yl)-methylene)hydrazinecarbothioamides with 2-(2-oxoindolin-3-ylidene)malononitrile in pyridine as a solvent. The structure assignment of all obtained products has been confirmed by H-1, C-13 NMR, 2D-NMR, N-15 NMR spectroscopy in addition to elemental analyses. The possible mechanism for the reaction is also discussed. (C) 2020 Published by Elsevier B.V.

Spontaneous resolution and crystal structure of (2S)-2-(3-nitrophenyl)-3-phenyl-2,3,5,6-tetrahydro-4H-1,3-thiazin-4-one; crystal structure of rac-2-(4-nitrophenyl)-3-phenyl-2,3,5,6-tetrahydro-4H-1,3-thiazin-4-one

The crystal structures of isomeric rac-2-(4-nitrophenyl)-3-phenyl-2,3,5,6-tetra-hydro-4H-1,3-thiazin-4-one (C16H14N2O3S) (1) and (2S)-2-(3-nitrophenyl)-3-phenyl-2,3,5,6-tetrahydro-4H-1,3-thiazin-4-one (C16H14N2O3S) (2) are reported here. While 1 crystallizes in a centrosymmetric space group, the crystal of 2 chosen for data collection has molecules only with (2S) chirality. This is the result of spontaneous resolution during crystallization, as the synthesis produces a racemic mixture. A crystal with (2R) molecules was also found in the same crystallization vial (structure factors available). The six-membered thiazine ring in both 1 and 2 displays an envelope conformation with the S atom forming the flap. The aryl rings in both structures adopt an approximate V shape with angles between their planes of 46.97 (14)degrees in 1 and 58.37 (10)degrees in 2. In both structures, the molecules form layers in the ab plane. Within such a layer in 1, one of the O atoms of the nitrophenyl group accepts a C-H center dot center dot center dot O hydrogen bond from the CH group at position 5 of the thiazine ring of a molecule of opposite chirality, forming chains along the a-axis direction. Each of the thiazine rings also participate in C-H center dot center dot center dot O bonds with the same carbon atom as above, resulting in chains along the b-axis direction, albeit of monochiral type. Adjacent layers are consolidated along the c-axis direction by pairs of parallel hydrogen bonds (C-H center dot center dot center dot O type) between the nitrophenyl groups of enantiomers. In 2, the two (C-H center dot center dot center dot O hydrogen bonds contribute to chain formation along the b-axis direction. Weak edge-to-face interactions between the aryl groups of neighbouring molecules in 1, and C-H center dot center dot center dot pi interactions between a thiazine ring CH group and a phenyl group of a neighboring molecule in 2 are also observed.

Inhibition of heat shock protein (Hsp) 90 potentiates the antiproliferative and pro-apoptotic effects of 2-(4 ‘ fluoro-phenylamino)-4H-1,3-thiazine[6,5-b]indole in A2780cis cells

Ovarian carcinoma is initially sensitive to platinum-based therapy, but become resistant over time. The study of cancer sensitizing substance is therefore the major challenge for a number of scientific groups. Our experiments were carried out on human ovarian adenocarcinoma A2780cis cells resistant to cisplatin and their response to 2-(4’fluoro-phenylamino)-4H-1,3-thiazine[6,5-b] indole (thiazine[6,5-b] indole) and/or heat shock protein (Hsp) 90 inhibitor 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG) using proliferation assay, cell cycle analysis and monitoring of apoptosis were examined. A2780cis cells revealed the same fold of resistance to Hsp90 inhibitor 17-DMAG as it is declared for cisplatin (18 times), but only 3.2 times for thiazine[6,5-b] indole. Our results showed that the combination of thiazine[6,5-b] indole and 17-DMAG significantly reduced proliferation of A2780cis cells and led to their accumulation in G2/M phase of the cell cycle. Moreover, both thiazine[6,5-b] indole as well as 17-DMAG increased the number of annexin V positive A2780cis cells in time dependent manner. Interestingly, thiazine[6,5-b] indole treatment significantly activated also caspase-3 compared to untreated or 17-DMAG-treated cells and reduced mitochondrial membrane potential (MMP) of A2780cis cells with more significant decline after combined treatment. In this regard, the incubation of A2780cis cells with thiazine[6,5-b] indole induced PARP protein cleavage as well as an increased level of Bad protein with more pronounced changes after combined treatment. Importantly, Hsp70 protein was not upregulated in A2780cis cells neither by individual treatment nor by mutual combination. Our results signify antiproliferative and pro-apoptotic effects of novel thiazine[6,5-b] indole potentiated by Hsp90 inhibitor 17-DMAG in ovarian adenocarcinoma cells resistant to cisplatin and therefore represents new strategy in cancer treatment.

Titania-loaded cellulose-based functional hybrid nanomaterial for photocatalytic degradation of toxic aromatic dye in water

The dispersion of Titania on cellulose nanowhiskers was achieved using titanium tetra-isopropoxide as the precursor and sulphuric acid as a peptizing agent via the low-temperature sol-gel synthesis method. The photocatalytic activity of the resultant hybrid catalyst was studied through photocatalytic removal of toxic aromatic cationic thiazine dye (methylene blue). Diverse instrumental methods used for full characterizations of pristine and prepared materials allowed correlating the type of the chemical moiety incorporated to the formation of Titania-loaded cellulose-based functional nanomaterial as well as its stability and catalytic performance. Results indicated successful synthesis of multiscale Titania (19 nm similar to 1 mu m) and perpetual distribution over cellulose nanowhiskers. The latter showed high photocatalytic behavior towards the degradation of methylene blue (conc. 50 ppm) dye. The degradation reached 98.5 % in 40 min at a reaction rate of 0.188 min(-1) as observed and measured through UV-vis spectrophotometer. Chemical oxygen demand (COD) analysis reveals substantial mineralization of the pollutants by reducing toxicity up to 68.64 % with complete recovery of the catalyst validated by total dissolved solids (TDS) analysis of treated water. Considering the above results, a mechanism has postulated. Kinetic study showed that the degradation reaction obeys pseudo-first-order reaction kinetics with appreciable recyclability after five (05) repeated uses. The results herein open new prospects for cellulose-based functional nanomaterial for various environmental applications.

New pyrimidothiazine Derivative as Corrosion Inhibitor for Carbon Steel in Acidic Media

2,8-bis(4-chlorophenyl)-3-hydroxy-4,6-dioxo-4,6-dihydropyrimido[2,1-b][1,3]thiazine-7-carbonitrile (CHPTC) was tested as corrosion inhibitor for carbon steel in 2.0 M H3PO4 by using polarization, electrochemical impedance spectroscopy (EIS) and computational calculations. Potentiodynamic polarization curves indicated that the pyrimidothiazine derivativeas mixed-type inhibitor. Impedance measurements showed that the double-layer capacitance decreased and charge-transfer resistance increased with increase in the inhibitor concentration and hence increasing in inhibition efficiency. The effect of temperature on the corrosion behavior of carbon steel in 2.0 M H3PO4 with and without addition of CHPTC was studied in the temperature range 313-333 K. The adsorption of the inhibitor molecules was in accordance with the Langmuir adsorption isotherm. Quantum chemical approach used to calculate electronic properties of the molecule to ascertain the relation between inhibitive effect and molecular structure.
