Background: The aim of this study was to compare antimicrobial photodynamic therapy (aPDT) as an adjunctive therapy to scaling and root planing (SRP) for the treatment of experimentally induced periodontitis in ovariectomized (OVX) rats that were or were not treated with estrogen replacement. Methods: A total of 270 female rats were divided into 3 groups: N, normal; O, OVX; and OE, OVX with estrogen replacement. Periodontal disease was induced through the introduction of a cotton thread around the first left mandibular molar. After 7 days, the ligature was removed, and the animals were randomically divided into the following treatment groups: SRP, SRP plus saline solution; LLLT, SRP plus low-level laser therapy (LLLT); and aPDT, SRP plus toluidine blue-O (TBO) irrigation followed by LLLT. Ten animals from each group were euthanized at days 7, 15, and 30 after dental treatment. Bone loss (BL) in the furcation region was evaluated using histometric and immunohistochemical analyses. Results: aPDT treatment resulted in reduced BL compared to SRP treatment at all time points. Additionally, aPDT-treated rats exhibited reduced numbers of TRAP-positive cells and more PCNA-positive cells in all treatment groups regardless of estrogen status. Whereas aPDT-treated rats showed weak RANKL immunoreactivity at day 7 post-treatment, strong OPG immunoreactivity was observed at day 15 post-treatment. Conclusions: aPDT was an effective adjunctive therapy for the treatment of periodontitis in ovariectomized rats that were or were not given estrogen replacement therapy.

Bite of Arsenic, with Kathryn Cottingham. Interviewed by Ashley Ahearn.

Many organic foods and high-energy products are sweetened with brown rice syrup as an alternative to high-fructose corn syrup. Consumers who eat these products may be avoiding high-fructose corn syrup, but they also may be exposed to arsenic that's been absorbed by the rice plants from which the syrup is made. In this podcast, Kathryn Cottingham talks with host Ashley Ahearn about her recent market-basket study of products containing brown rice syrup and other rice-based ingredients. Arsenic was detected in all the products tested, although Cottingham cautions it's too soon to say what this means in terms of potential health effects.

System identification algorithm analysis of acupuncture effect on mean blood flux of contralateral hegu acupoint.

Background. Acupoints (belonging to 12 meridians) which have the same names are symmetrically distributed on the body. It has been proved that acupoints have certain biological specificities different from the normal parts of the body. However, there is little evidence that acupoints which have the same name and are located bilaterally and symmetrically have lateralized specificity. Thus, researching the lateralized specificity and the relationship between left-side and right-side acupuncture is of special importance. Methodology and Principal Findings. The mean blood flux (MBF) in both Hegu acupoints was measured by Moor full-field laser perfusion imager. With the method of system identification algorithm, the output distribution in different groups was acquired, based on different acupoint stimulation and standard signal input. It is demonstrated that after stimulation of the right Hegu acupoint by needle, the output value of MBF in contralateral Hegu acupoint was strongly amplified, while after acupuncturing the left Hegu acupoint, the output value of MBF in either side Hegu acupoint was amplified moderately. Conclusions and Significance. This paper indicates that the Hegu acupoint has lateralized specificity. After stimulating the ipsilateral Hegu acupoint, symmetry breaking will be produced in contrast to contralateral Hegu acupoint stimulation.
