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.

ANTICONVULSANT EVALUATION OF SOME NOVEL 1, 3-THIAZINE DERIVATIVES

In the present study, a series of novel biologically active 8-benzylidene-6-tert-butyl-4-phenyl-5, 6, 7, 8-tetrahydro-benzo-1, 3-thiazin – 2 -imines (TB1-TB12) were synthesized and evaluated for their biological activities. Initially, 2,6-dibenzylidene-4-tert-butylcyclohexanones were synthesized by Claisen-Schmidt condensation of 4-tert-butylcyclohexanone with various aromatic aldehydes in the presence of dilute sodium hydroxide. Further these compounds were subjected to cyclocondensation with thiourea, in isopropyl alcohol, catalyzed by aqueous potassium hydroxide to form 4-aryl-8-arylidene-5,6,7,8-tetrahydro-1H-benzo[d][1,3] thiazin-2(4H)-imines (TB1-TB12). The structures of the newly synthesized compounds have been established on the basis of their spectral data and elemental analysis. Anticonvulsant activity was performed by Maximal electroshocks (MES) method by using Diazepam as standard reference. These compounds were subjected to molecular properties prediction, drug-likeness, lipophilicity and solubility parameters determination using Molinspiration, Osiris program was used for prediction of the toxicity, and also Molsoft and ALOGPS 2.1 softwares. Among all compounds TB5 and TB8 containing lipophilic methoxyl and isopropyl group were more potent whereas TB12 containing hydroxyl groups were least potent among the series.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 66-27-3 is helpful to your research. Quality Control of Methyl methanesulfonate.

Sulthiame add-on therapy for epilepsy

Background Epilepsy is a common neurological condition characterised by recurrent seizures. Most patients respond to conventional antiepileptic drugs, however, around 30% will continue to experience seizures despite multiple antiepileptic drugs. Sulthiame, also known as sultiame, is a widely used antiepileptic drug in Europe and Israel. We present a summary of the evidence for the use of sulthiame as add-on therapy in epilepsy. Objectives To compare the efficacy and side-effect profile of sulthiame as add-on therapy compared with placebo or another antiepileptic drug. Search methods We searched the Cochrane Epilepsy Group’s Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, ClinicalTrials.gov and the WHO ICTRP Search Portal on 11 August 2015. No language restrictions were imposed. We contacted the manufacturers of sulthiame and researchers in the field to seek any ongoing or unpublished studies. Selection criteria Randomised controlled add-on trials of sulthiame in people of any age with epilepsy of any aetiology. Data collection and analysis Two review authors independently selected trials for inclusion and extracted relevant data. The following outcomes were assessed: 1) reduction in seizure frequency of 50% or greater between baseline and end of follow-up; 2) complete cessation of seizures during follow-up; 3) mean seizure frequency; 4) time to treatment withdrawal; 5) adverse drug effects; and 6) quality of life scoring. Primary analyses were intention-to-treat. We present a narrative analysis. Main results We included one trial with 37 participants with a new diagnosis of West syndrome. Sulthiame was given as an add-on therapy to pyridoxine. No data were reported for outcomes 1), 3) or 6). Overall risk ratio with 95% confidence intervals (CI) for complete cessation of seizures during a nine-day follow-up period versus placebo was 0.71 (95% CI 0.53 to 0.96). Meaningful analysis of time to treatment withdrawal and adverse drug effects was not possible due to incomplete data. Authors’ conclusions Sulthiame may lead to a cessation of seizures when used as an add-on therapy to pyridoxine in patients with West syndrome. The included study was small and had a significant risk of bias which limits the impact of the evidence. No conclusions can be drawn about the occurrence of adverse drug effects, change in quality of life or mean reduction in seizure frequency. No evidence exists for the use of sulthiame as an add-on therapy in patients with epilepsy outside West syndrome. Large, multi-centre randomized controlled trials are necessary to inform clinical practice if sulthiame is to be used as an add-on therapy for epilepsy.

Removal of Synthetic Dyes by Dried Biomass of Freshwater Moss Vesicularia Dubyana: A Batch Biosorption Study

In this work the biosorption of cationic dyes thioflavin T (TT) and methylene blue (MB) from single and binary solutions on dried biomass of freshwater moss Vesicularia dubyana as a function of contact time, pH, and biomass or sorbate concentration has been investigated. The prediction of maximum sorption capacities using adsorption isotherm models were also realized. Biosorption of TT and MB is a rapid process strongly affected by solution pH. Maximum sorption capacities Q(max) calculated from Langmuir isotherm were 119 +/- 11 mg/g for TT and 229 +/- 9 mg/g for MB. In binary mixture, the presence of MB caused significant decrease of TT sorption, advocating the competitive sorption between TT and MB. Results revealed that V. dubyana biomass exhibited significantly higher affinity to thiazine dye MB in comparison with benzothiazole dye TT from both single and binary solutions. Based on the obtained results, the competitive effects in binary system can substantially influence the sorption process and should be thoroughly evaluated before application of selected adsorbents for removal of basic dyes from colored effluents.

Spectroscopic, thermal, antimicrobial and molecular modeling studies of mononuclear pentafunctional Schiff base metal chelates derived from 5-acetyl-4-hydroxy-2H-1,3-thiazine-2,6(3H)-dione

A new pentafunctional N3O2 Schiff base, H2L ligand, and its metal chelates with Cu(II), Ni(II), Co(II), VO(IV), Zn(II), Cd(II), Ce(III), Cr(III), Fe(III) and UO2(VI) have been synthesized and characterized by elemental analysis, spectral, molar conductance, magnetic and thermal gravimetric studies. The results showed that the complexes have octahedral geometry except UO2 complex which has pentagonal bipyramidal arrangement. The TGA analyses suggest high stability for most complexes followed by thermal decomposition in different steps. The kinetic and thermodynamic parameters for decomposition steps of metal complexes thermograms have been calculated. Molecular orbital calculations were performed for the ligand and its metal complexes by means of hyperchem 7.52 program on the bases of semiempirical PM3 level and the results were correlated with the experimental data. The antimicrobial activity of the synthesized compounds were tested in vitro against some Gram-positive and Gram-negative bacteria; yeast and fungus strains and the results were discussed in terms of extended Lewis acid-base interactions.

Kinetics of palladium nano-particles catalyzed reduction of Methylene Green by hydrazine: Role of induction period in determining mechanistic pathway

Methylene Green (MG), a thiazine dye, is catalytically reduced by N2H4 in presence of palladium nanoparticles (Pdn) in buffer media. The observed rate, k(o) increases with increase in [Pdn], [N2H4] and pH but decrease with increase in ionic strength (maintained with NaNO3). Unlike other thiazine dyes, the catalyzed reduction of MG shows an induction period which is caused by the restructuring of Pdn surface. The rate of adsorbate-induced surface restructuring which increase with increase in [N2H4] but independent of [MG], suggest that only N2H4 is adsorbed on Pdn surface during the catalyzed reaction. Interestingly, NO3 ions are also adsorbed on the Pdn surface and turn the surface negatively charged. The reductant, N2H4 is adsorbed on this negatively charged Pdn surface before it reacts with MG. The surface restructuring energy of Pdn, though is constant (78.8 +/- 1.6 kJ M-1) over the temperature range of 288-313 K but the activation energy for the catalyzed reduction varies with temperatures. The convex Arrhenius plot illustrates that activation energy is different in lower (288-304 K, 123.8 +/- 12.6 kJ M-1) and higher temperature range (304-313 K, 69.2 +/- 2.1 kJ M-1) and around the inversion temperature, Tinv (304 K) a change in the nature of transition state takes place.
