Abstract:

Disinfeksi sistem saluran akar gigi sangat penting dalam perawatan saluran akar gigi. Instrumenmekanik dan agen desinfeksi atau larutan irigasi seperti NaOCL tidak efektif mengurangi jumlahbakteri di dalam saluran akar yang terinfeksi karena anatomi akar gigi yang kompleks. Kegagalanperawatan endodontik sering meninggalkan bakteri di sistem saluran akar gigi. Enterococcus faecalismerupakan salah satu mikroorganisme terpenting yang bertanggungjawab pada kegagalan perawatansaluran akar gigi. Bakteri ini kebal terhadap agen antimikroba dan mampu berkoloni membentukbiofilm di saluran akar gigi. Saat ini perangkat baru seperti photoactivated disinfection telah dicobauntuk disinfeksi saluran akar gigi. Photoactivated disinfection merupakan strategi antimikroba yangmenggunakan energi laser berkekuatan rendah untuk mengaktivasi suatu pewarna tidak toksik yangdiaktivasi sinar (photosensitizer). Energi yang dipindahkan dari photosensitizer teraktivasi ke oksigenyang tersedia, akan membentuk oksigen singlet sebagai spesies oksigen toksik. Spesies oksigen yangsangat reaktif secara kimia ini dapat merusak membran dan DNA bakteri patogen. Beberapapenelitian menunjukkan bahwa photoactivated disinfection dapat efektif mengurangi E.faecalis didalam saluran akar selama prosedur antimikroba bila digunakan bersama dengan prosedur disinfeksikonvensional untuk sterilisasi saluran akar. Photoactivated disinfection merupakan pendukung untukprotokol standar disinfeksi saluran akar gigi.Kata kunci: photoactivated disinfection, Enterococcus faecalis, perawatan saluran akar.

Abstract:

AbstractThe well-known photosensitizers hypericin, harmane, and emodin are typical pigments of certain mushroom species—is this a coincidence or an indication towards a photoactivated defense mechanism in the phylum Basidiomycota? This perspective article explores this hypothesis by cross-linking the chemistry of fungal pigments with structural requirements from known photosensitizers and insights from photoactivated strategies in the kingdom Plantae. Thereby, light is shed on a yet unexplored playground dealing with ecological questions, photopharmaceutical opportunities, and biotechnological potentials.

Abstract:

The Light Emitting Diodes (LED) technology has been used to photoactivate composite resins and there is a great number of published studies in this area. However, there are no studies regarding resin-modified glass-ionomer cements (RMGIC), which also need photoactivation. Therefore, the aim of this study was to evaluate water sorption of two RMGIC photoactivated with LED and to compare this property to that obtained with a halogen light curing unit. A resin composite was used as control. Five specimens of 15.0 mm in diameter x 1.0 mm in height were prepared for each combination of material (Fuji II LC Improved, Vitremer, and Filtek Z250) and curing unit (Radii and Optilight Plus) and transferred to desiccators until a constant mass was obtained. Then the specimens were immersed into deionized water for 7 days, weighed and reconditioned to a constant mass in desiccators. Water sorption was calculated based on weight and volume of specimens. The data were analyzed by two-way ANOVA and Tukey test (p < 0.05). Specimens photocured with LED presented significantly more water sorption than those photocured with halogen light. The RMGIC absorbed statistically significant more water than the resin composite. The type of light curing unit affected water sorption characteristics of the RMGIC.

Abstract:

The photochemistry of two anthracene-appended cobalt(iii) cyclam complexes is explored with a view to demonstrate a photoactivated ligand release process. The ligand exchange processes that occur in the complexes cis-[CoL(NO2)(ONO)]+ and trans-[CoL(NO2)(ONO)]+ in which L = 6-(anthracen-9-ylmethyl)-1,4,8,11-tetraazacyclotetradecane were monitored upon illumination of the anthracenyl chromophore at 360 nm in the presence of a large excess of thiocyanate. The trans-[CoL(NO2)(ONO)]+ complex underwent a ligand exchange reaction in the absence of light and displayed an enhancement of the reaction upon illumination. In contrast the cis-[CoL(NO2)(ONO)]+ complex was stable in the dark but displayed a significant quantum yield of photoactivated ligand release (Φ = 0.19). It is proposed that in cis-[CoL(NO2)(ONO)]+ the photoexcited anthracenyl chromophore undergoes efficient energy transfer to the cobalt(iii) cyclam before ligand exchange. Complexes based on the anthracenylcyclam–cobalt(iii) framework may be potentially useful candidates as photoactivated ligand release systems.

Abstract:

Using the push-out test, this study evaluated the bond strength of the composite resin Z250 (3M/ESPE) photoactivated with the XL2500 (3M/ESPE) quartz-tungsten-halogen light-curing unit with different curing protocols: soft-start (150 mW/cm2 for 2 s (S2), 3 s (S3), 5 s (S5), 10 s (S10) or 15 s (S15), followed by 700 mW/cm2 for 15 s; pulse-delay (150 mW/cm2 for 2 s (P2), 3 s (P3), 5 s (P5), 10 s (P10) or 15 s (P15), with a 1-min delay, followed by 700 mW/cm2 for 15 s. After storage at 37oC ± 1 for 24 h ± 1, the specimens were ground, polished and subjected to a push-out test in a universal test machine (Instron) with a cell load of 500 N at a crosshead speed of 0.5 mm/min. The data were analyzed statistically by ANOVA and Tukey's test at 5% significance level. There were no statistically significant differences (p>0.05) among the groups photoactivated using the soft-start mode. For the pulse-delay mode, P5 promoted the highest bond strength (p<0.05). Groups photoactivated with the pulse-delay mode (except for P2 and P15) presented significantly higher bond strength than those photoactivated with the soft-start. It may be concluded that the influence of initial exposure time was curing method-dependent, with the best results obtained using the pulse-delay method with 5 s in the first photoactivation cycle.

Abstract:

The aim –to investigate the effect of photoactivated coproporphyrin III (KP III) on microcirculation in the rat mesenteric vascular bed. Material and methods. The study was performed on 20 male rats, divided into 4 groups: 1) control; 2) KP III; 3) laser irradiation; 4) laser irradiation on combined with prior administration of the KP III.The objectof the study was venules (20–40 µm) of the mesentery of the small intestine. The study of blood flow velocity in the venules was performed using the method of intravital biomicroscopy. The velocity parameters were registered using a high-speed video camera Basler acA2000 (Germany). Coproporphyrin III (Elast, Russia) at a dose of 10 mg/kg was injected into the tail vein 3 hours before laser irradiation. Irradiation was performed using a Lakhta Milon semiconductor laser apparatus (Qualitek, Russia) (λ=635 nm, 0.1 W/cm2 ; 300 s; 30 J/cm2 ).Results.Administration of KP III without subsequent irradiation did not affect the blood flow velocity during the entire observation period. Laser irradiation of venules without prior administration of KP III led to an increase in blood flow velocity by 39.1 % (p<0.05). After laser irradiation and administration of KPIII, there was a gradual decrease in flow velocity after the photoactivation process.Conclusions. We studied the effect of photoactivated KP III on microcirculation in the mesentery of the small intestine of rats. Changes in the blood flow velocity in the venules of the mesentery affected by KP III and laser irradiation develop mainly in the post-radiation period and could be associated with endothelial dysfunction.

Abstract:

Proteins of the GFP (green fluorescent protein) family have revolutionized life sciences because they allow the tagging of biological samples in a non-invasive genetically encoded way. ‘Phototransformable’ fluorescent proteins, in particular, have recently attracted widespread interest, as their fluorescence state can be finely tuned by actinic light, a property central to the development of super-resolution microscopy. Beyond microscopy applications, phototransformable fluorescent proteins are also exquisite tools to investigate fundamental protein dynamics. Using light to trigger processes such as photoactivation, photoconversion, photoswitching, blinking and photobleaching allows the exploration of the conformational landscape in multiple directions. In the present paper, we review how structural dynamics of phototransformable fluorescent proteins can be monitored by combining X-ray crystallography, in crystallo optical spectroscopy and simulation tools such as quantum chemistry/molecular mechanics hybrid approaches. Besides their usefulness to rationally engineer better performing fluorescent proteins for nanoscopy and other biotechnological applications, these investigations provide fundamental insights into protein dynamics.

Abstract:

The process of light adaptation in blowfly photoreceptors was analyzed using intracellular recording techniques and double and triple flash stimuli. Adapting flashes of increasing intensity caused a progressive reduction in the excitability of the photoreceptors, which became temporarily suppressed when 3 x 10(6) quanta were absorbed by the cell. This suppression was confirmed by subsequently applying an intense test flash that photoactivated a considerable fraction of the 10(8) visual pigment molecules in the cell. The period of temporary desensitization is referred to as the refractory period. The stimulus intensity to render the receptor cell refractory was found to be independent of the extracellular calcium concentration over a range of 10(-4) and 10(-2) M. During the refractory period (30-40 ms after the adapting flash) the cell appears to be "protected" against further light adaptation since light absorption during this period did not affect the recovery of the cell's excitability. Calculations showed that the number of quantum absorptions necessary to induce receptor refractoriness is just sufficient to photoactivate every microvillus of the rhabdomere. This coincidence led to the hypothesis that the refractoriness of the receptor cells is due to the refractoriness of the individual microvilli. The sensitivity of the receptor cells after relatively weak adapting flashes was reduced considerably more than could be accounted for by the microvilli becoming refractory. A quantitative analysis of these results suggests that a photoactivated microvillus induces a local adaptation over a relatively small area of the rhabdomere around it, which includes several tens of microvilli. After light adaptation with an intense flash, photoactivation of every microvillus by the absorption of a few quanta produced only a small receptor response whereas photoactivation of every rhodopsin molecule in every microvillus produced the maximum response. The excitatory efficiency of the microvilli therefore increases with the number of quanta that are absorbed simultaneously.
