New banana shaped A?D?pi?D?A type organic dyes containing two anchoring groups for high performance dye-sensitized solar cells

Two new bent A?D?pi?D?A type organic dyes (MA-1 and MA-2) consisting of carbazole and phenothiazine moieties as electron donors with 2,1,3-benzothiadiazole as a pi-linker with two end-anchoring groups are designed, synthesized and tested in DSSCs. The photophysical and electrochemical properties of the dyes are investigated in detail. Incorporation of phenothiazine unit in MA-2 resulted in high HOMO level (0.62?V vs. NHE), with a red shift in absorption maxima and broadening of the absorption spectrum. Under standard global AM 1.5 solar conditions, the MA-2 sensitized solar cells exhibited a short circuit photocurrent density of 13.1?mA?cm?2, an open-circuit voltage of 0.73?V, a fill factor of 0.72, corresponding to an overall conversion efficiency of 6.87%. Such design and development of molecular dyes are useful for improving the overall efficiency of DSSCs.

13C Nuclear Magnetic Resonance of Some Derivatives of Phenothiazines, Pyridobenzothiazines and Phenoxazines

Natural abundance 13C NMR studies were carried out on a series of phenothiazines, pyridobenzothiazines and phenoxazines.Chemical shift assignments were made on the basis of models, coupling patterns and aromatic substituent affects.For most of the compounds studied, substituents influence only the carbon chemical shifts of the substituted carbocyclic ring, while the chemical shifts of the unsubstituted ring are essentially the same as those of the parent heterocyclic compound.However, the 10-acetyl and 4′-nitro-10-phenyl groups affect the chemical shifts of several of the carbon atoms in the phenothiazine nucleus.An explanation in terms of resonance interactions between these groups and the N-10 lone-pair electrons is presented.

Is antimicrobial photodynamic therapy effective as an adjunct to scaling and root planing in patients with chronic periodontitis? A systematic review

The aim of this systematic review was to investigate whether antimicrobial photodynamic therapy (aPDT) as either a primary mode of treatment or an adjunct to non-surgical treatment was more effective than scaling and root planing (SRP) alone in treating chronic periodontitis in terms of clinical attachment level (CAL) gain and probing depth (PD) reduction. The focused question was developed using the Patient, Intervention, Comparison, and Outcome (PICO) format, and two authors independently searched the Medline, EMBASE, Cochrane Library, Web of Science, Google Scholar, and Scopus databases for relevant studies from January 2008 to December 2016. Twenty studies included in this systematic review were randomized clinical trials (RCTs) or quasi-RCTs of aPDT compared to placebo, no intervention, or non-surgical treatment in an adult population. Basic study characteristics, photosensitizing agents and wavelengths used in aPDT, frequency of aPDT application, effect of aPDT on clinical parameters, antimicrobial effect of aPDT in chronic periodontitis, effect of immunological parameters following aPDT and patient-based outcome measures were collected from the studies. Although there was a wide range of heterogeneity in the included studied, they all indicated that aPDT has the potential to be an effective adjunct in the treatment of chronic periodontitis. Long-term, multicenter studies with larger sample sizes are needed before aPDT can be recommended as an effective treatment modality.

Photodynamic therapy for the treatment of peri-implant diseases: A network meta-analysis of randomized controlled trials

Background Photodynamic therapy in peri-implantitis has been tested in randomized clinical trials. Though systematic review and meta-analysis on human and animal studies, identifies the utility of photodynamic therapy, a comparison of other interventions with photodynamic therapy for peri-implantitis does not exist. Hence the aim of this network meta-analysis is to identify the role of photodynamic therapy for peri-implantitis compared with other interventions tested in randomized human clinical trials. Method Randomized controlled trials comparing photodynamic therapy and other interventions in patients with peri- implantitis was searched for in electronic databases. The risk of bias was calculated using Cochrane risk of Bias tool. The heterogeneity between the studies in direct comparison was assessed using Chi-square and I2 tests. GRADE working group approach was used to assess the quality of evidence. Publication bias was assessed using Funnel plot and Trim and Fill method was used to identify the number of missing studies. Results We observed a significant reduction in the level of attachment scores with the use of combined photodynamic therapy with mechanical debridement when compared with other interventions tested. For bleeding on probing, pocket depth and plaque scores no statistically significant results were obtained. Conclusion The use of photodynamic therapy with mechanical debridement will definitely bring about significant improvement in patients with peri-implantitis. Further trials on the use of photodynamic therapy with other treatment modalities need to be tested to arrive at the best possible treatment option for peri-implantitis.

Antimicrobial efficacy of photodynamic therapy and light-activated disinfection against bacterial species on titanium dental implants

Purpose: The aim of this study was to evaluate the efficacy of photodynamic therapy (PDT) and light-activated disinfection (LAD) against a 3-day-old bacterial suspension prepared from three different bacterial species present on titanium dental implants, and to analyze the possible alterations of the implant surfaces as a result of the PDT and LAD. Materials and Methods: The study was conducted on 72 titanium dental implants contaminated with a bacterial suspension prepared from three bacterial species: Prevotella intermedia, Aggregatibacter actinomycetemcomitans, and Porphyromonas gingivalis. The contaminated implants were incubated under anaerobic conditions for 72 hours and then were randomly divided into four experimental groups and two control groups (n = 12 each), according to the following treatment protocols: group 1 (PDT1): PDT (660 nm, 100 mW, 60 seconds) with toluidine blue; group 2 (PDT2): PDT (660 nm, 100 mW, 60 seconds) with phenothiazine chloride dye; group 3 (LAD): light-emitting diode (LED) with toluidine blue; group 4 (toluidine blue): treatment with only toluidine blue for 60 seconds. In the positive control group, the implants were treated with a 0.2% chlorhexidine-based solution for 60 seconds, and in the negative control group, no treatment was used. Results: The highest bacterial reduction was recorded in the PDT1 (98.3%) and PDT2 (97.8%) groups. The results of this study showed that there was a statistically significant reduction of bacteria in the PDT1 and PDT2 groups compared with the negative control group (P < .05), individually for each bacterial species as well as for all three species together. LAD was less effective than PDT1 and PDT2, and did not show a statistically significant difference compared with the negative control or any other treatment group. Toluidine blue was the least effective treatment in terms of both the total bacterial count and the individual count for each bacterial species. Conclusion: Both PDT1 and PDT2 protocols showed a high efficacy against a 3-day-old bacterial biofilm on dental implants and were more effective compared with LAD. Do you like my blog?

A 2 – cyano phenothiazine preparation method (by machine translation)

The invention relates to a preparation method of 2-cyanophenothiazine. Dehydration reaction is firstly performed, thereby avoiding the complex technical step of performing dehydration refinement after the 2-cyanophenothiazine crude product is generated, and effectively reducing the product decomposition; meanwhile, the 2-cyanophenothiazine generation reaction is performed after dehydration to obviously reduce the recrystallization frequency in the refinement process, so that the recrystallization is only needed once, thereby greatly reducing the loss of the materials and energy sources, lowering the preparation cost and enhancing the reaction yield; and thus, the yield of the preparation method can reach 90.3% or above. Besides, the purity of the product is very high and can reach 99.5% or above, and the content of the impurity amide is less than 0.1%. In addition, the catalyst used by the method can effectively accelerate the reaction, shorten the reaction time and lower the reaction temperature, thereby enhancing the energy utilization ratio and further lowering the cost of the whole preparation process.
