The use of topical ozone to treat recurrent aphthous ulceration

This article is included with the publisher's permission. More information about the journal can be found at the publisher's website at: http://www.dentalasia.net/index.htmRecurrent aphthous ulceration is a common mucosal disorder that can be painful and debilitating for patients. This type of ulceration has been associated with systemic disease and it has been suggested that a variety of immunological, microbial and genetic factors may all play a role in its aetiopathogenesis. A wide variety of treatment strategies for aphthous ulceration has been discussed in the literature. This case report demonstrates the beneficial use of topical application of ozone using the Healozone‘ appliance (Kavo) in a patient with long standing aphthous ulceration involving the lateral border of the tongue. The topical application of ozone provided an effective means of producing resolution of clinical symptoms related to aphthous ulceration for this patient. Further clinical investigation is required in order to determine the potential of this treatment modality in the treatment of recurrent aphthous ulceration.Richard Loga

Hate Speech and the Status of Prisoners

Drawing from feminist and critical race theorists’ analyses of pornography and racist speech, I advance an argument in favor of speech regulations vis-à-vis prison rape films. I call ‘prison rape films’ (PRFs) those films that depict prison rape humorously, as narrative springboards, or as unnecessary tangents. I explore why such films ought to be regulated by pointing out the harms these films have on prisoners. In doing so, I examine what it is to be a ‘historically oppressed group’ and what makes such groups particularly vulnerable to hate speech. Prisoners are a historically oppressed group that is harmed by prison rape films and, on this basis, deserve protection from such harm by way of regulation

State-of-the-art all-silicon sub-bandgap photodetectors at telecom and datacom wavelengths

Silicon-based technologies provide an ideal platform for the monolithic integration of photonics and microelectronics. In this context, a variety of passive and active silicon photonic devices have been developed to operate at telecom and datacom wavelengths, at which silicon has minimal optical absorption - due to its bandgap of 1.12 eV. Although in principle this transparency window limits the use of silicon for optical detection at wavelengths above 1.1 μm, in recent years tremendous advances have been made in the field of all-silicon sub-bandgap photodetectors at telecom and datacom wavelengths. By taking advantage of emerging materials and novel structures, these devices are becoming competitive with the more well-established technologies, and are opening new and intriguing perspectives. In this paper, a review of the state-of-the-art is presented. Devices based on defect-mediated absorption, two-photon absorption and the internal photoemission effect are reported, their working principles are elucidated and their performance discussed and compared

Are Patents Impeding Medical Care and Innovation?

This month's debate examines whether the current patent system is crucial for stimulating health research or whether it is stifling biomedical research and impeding medical care. Background to the debate: Pharmaceutical and medical device manufacturers argue that the current patent system is crucial for stimulating research and development (R&D), leading to new products that improve medical care. The financial return on their investments that is afforded by patent protection, they claim, is an incentive toward innovation and reinvestment into further R&D. But this view has been challenged in recent years. Many commentators argue that patents are stifling biomedical research, for example by preventing researchers from accessing patented materials or methods they need for their studies. Patents have also been blamed for impeding medical care by raising prices of essential medicines, such as antiretroviral drugs, in poor countries. This debate examines whether and how patents are impeding health care and innovation

An automated identification and analysis of ontological terms in gastrointestinal diseases and nutrition-related literature provides useful insights

With an unprecedented growth in the biomedical literature, keeping up to date with the new developments presents an immense challenge. Publications are often studied in isolation of the established literature, with interpretation being subjective and often introducing human bias. With ontology-driven annotation of biomedical data gaining popularity in recent years and online databases offering metatags with rich textual information, it is now possible to automatically text-mine ontological terms and complement the laborious task of manual management, interpretation, and analysis of the accumulated literature with downstream statistical analysis. In this paper, we have formulated an automated workflow through which we have identified ontological information, including nutrition-related terms in PubMed abstracts (from 1991 to 2016) for two main types of Inflammatory Bowel Diseases: Crohn’s Disease and Ulcerative Colitis; and two other gastrointestinal (GI) diseases, namely, Coeliac Disease and Irritable Bowel Syndrome. Our analysis reveals unique clustering patterns as well as spatial and temporal trends inherent to the considered GI diseases in terms of literature that has been accumulated so far. Although automated interpretation cannot replace human judgement, the developed workflow shows promising results and can be a useful tool in systematic literature reviews.

Rethinking the place of the family in the post-Covid church in the UK: an exploration of families’ engagement with church during and after Covid

The family's role in nurturing children's faith became critical during the Covid-19 pandemic. The ways that churches addressed the needs of these families during the pandemic revealed much about church leaders’ understanding of the place of the family in Church. This article looks at faith nurture in the family and role of the church in this task. Robust connections between church and family which are essential for the holistic nurturing of child’s faith were disrupted by Covid-19 restrictions. The research involved an online survey of 175 church leaders and 209 parents, with the addition of focus group interviews of 36 children and 18 parents in the aftermath of this disruption. The findings provide insights into church leaders, parents and children’s family ministry experience, and their hopes for future engagement. Data analysis revealed the severity of the disruption and a sense of disconnection between families and Church. The discussion argues this has had a lasting impact on family church relationships and considers parents’ hopes for a welcoming listening church community. In conclusion, we argue that there is an opportunity to learn from the pandemic experience, listen to parents and children and re-imagine the family's place in Church

The Prevalence of Lower Extremity Non-Contact Injuries in Athletic Populations in Relation to Measured Ankle Dorsiflexion

Context: Ankle dorsiflexion is the degree to which the dorsal aspect of the foot can be brought closer in relation to the shin. Restricted ankle dorsiflexion can cause altered biomechanics and loading patterns, which can lead to injury from over-compensation in movement patterns. Limited ankle dorsiflexion alters frontal and sagittal plane biomechanics and has been hypothesized to contribute to common lower extremity injuries. The weight-bearing lunge test is a simple clinical evaluation test that can measure the range of ankle dorsiflexion. Objective: The purpose of this study was to determine if there was a correlation between restricted range of motion with ankle dorsiflexion and lower extremity injuries. We hypothesized restricted range of motion at the ankle would lead to increased stress on other joints resulting in chronic stress injuries. Design: Cross-sectional study Setting: Athletic training clinic at a mid-west NAIA institution. Participants: One-hundred forty-eight college athletes (104 males and 44 females; age = 19.32 ± 1.21 years, height = 69.64 ± 4.89 inches, mass = 81.39 ± 18.57 kg) who were all fall sport athletes (football, N=70; women’s volleyball, N=17; men’s soccer, N=34 and women’s soccer, N=27) were the participants of this study. Some athletes were excluded from the study if they had suffered a lower extremity injury in the previous year. Main Outcome Measures: Ankle dorsiflexion range of motion measured using the weight-bearing lunge test; lower extremity noncontact injuries recorded via The Athletic Trainer System®. Results: Results were calculated using T-Tests via IBM SPSS® software. There was a total of 25 injured and 123 uninjured athletes. There was no statistical significance in ankle dorsiflexion between recorded injured and uninjured participants (p = 0.817). The average dorsiflexion for injured participants = 41.01° ± 6.28°. The average for uninjured = 41.85° ± 6.76°. Asymmetry between left and right ankle when compared to injured (2.1° ± 1.63°) vs. uninjured (2.49° ± 1.92°) was not significance (p = 0.290). Conclusion: There was no significant data to assume correlation or causation between restricted ankle dorsiflexion measured via the weight-bearing lunge test and increased risk of lower extremity noncontact injury. Lack of significance comparing asymmetry between left and right leg in both injured and uninjured groups provided further support for this conclusion

Quantitative Reef Assessment Studies in Bermuda: A Comparison of Methods and Preliminary Results

To compare in quantitative terms both ecological characteristics of the stony coral fauna at various reef sites in Bermuda and available assessment methodologies, we present a study of four separate methods at each of three reef sites. Three plotless (Intersected-length, Quarter point, Point) and one quadrat (Belt-quadrat) methods were employed. Each technique gave similar results but had inherent advantages and disadvantages which involve trade-offs in quantity and type of information generated and time required for use.Pooling of method results revealed that total coral coverage was highest at North Rock (26%), intermediate at Three Hill Shoals (17%), and lowest at South shore (13%). Diversity statistics were highest at Three Hill Shoals, intermediate at North Rock, and lowest at South shore. At all three sites the most dominant species in terms of coverage was Diplaria strigosa; six coral species accounted for 90% of the total coral coverage.This study represents a quantitative comparison of the results and performance of common reef assessment methodologies and the first truly quantitative data on coral coverage, diversity, and distribution for selected reef sites in Bermuda
