Objectives: The Temporo-Mandibular Disorders (TMD) are a set of dysfunctional patterns concerning the temporo-mandibular joints (TMJ) and the masticatory muscles; its main symptom is pain, probably caused by inflammatory changes in the synovial membrane, alterations in the bone marrow of the mandibular condyle and impingement and compression. The aim of this preliminary study was to investigate the effectiveness in the TMD pain reduction of a new laser device recently proposed by the commerce that, due to its reduced dimensions and to be a class I laser according the ANSI classification, may be used at home by the patient himself.Materials and methods: Twenty-four patients with TMD were randomly selected: the inclusion criteria for the sample was the diagnosis of mono- or bi-lateral TMD, with acute pain restricted to the joint area, associated with the absence of any muscle tenderness during palpation. The patients were randomly assigned to two groups:Group 1 (12 patients): patients receiving real LLLT (experimental group).Group 2 (12 patients): patients receiving inactive laser (placebo group).The treatment was performed once a day for two weeks with an 808 nm diode laser by the patient himself with irradiation of the cutaneous zone corresponding to the TMJ for 15 minutes each side. Each patient was instructed to express its pain in a visual analogue scale (VAS) making a perpendicular line between the two extremes representing the felt pain level. Statistical analysis was realized with GraphPad Instat Software, where P<0.05 was considered significant and P<0.01 very significant.Results: The patient’s pain evaluation was expressed in the two study groups before the treatment, 1 week and two weeks after the treatment. The differences between the two groups result extremely significant with p<0.0001 for the comparison of VAS value after 1 and 2 weeks.Conclusions: This study, even if it may be considered such a pilot study, investigated a new way to control the pain in the temporo-mandibular diseases by an at home self administered laser device. Results are encouraging, but they will have to be confirmed by greater studies.

On April 26 in 1986, the catastrophe at Chernobyl unit-4 reactor occurred about 100 km north of Kiev in the Ukraine. A lot of radioactivity was released from the damaged reactor into the environment. A vast land and many people living there were contaminated by the radioactivity. After about 7 days the radioactivity reached Japan, a remote country about 8,000 km from Chernobyl and was detected in all the prefectures there. Needless to say, the nuclear facility and its surrounding countryside have been highly polluted by the radioactivity. Naturally this radioactivity was found in people's bodies, too. The high concentration of 300 Bq/Ag (24,000 Bq at weight of 79 kg) was detected in the inhabitants living in Checherusk about 200 km north of Chernobyl in 1991. Some estimations of 10,000 to 400,000 deaths in the future due to cancer caused by the accident were reported. A catastrophe at only one nuclear reactor leads to global pollution by radioactivity and inflicts damage on people.

This paper presents a stewardship maturity assessment model in the form of a matrix for digital environmental datasets. Nine key components are identified based on requirements imposed on digital environmental data and information that are cared for and disseminated by U.S. Federal agencies by U.S. law, i.e., Information Quality Act of 2001, agencies’ guidance, expert bodies’ recommendations, and users. These components include: preservability, accessibility, usability, production sustainability, data quality assurance, data quality control/monitoring, data quality assessment, transparency/traceability, and data integrity. A five-level progressive maturity scale is then defined for each component associated with measurable practices applied to individual datasets, representing Ad Hoc, Minimal, Intermediate, Advanced, and Optimal stages. The rationale for each key component and its maturity levels is described. This maturity model, leveraging community best practices and standards, provides a unified framework for assessing scientific data stewardship. It can be used to create a stewardship maturity scoreboard of dataset(s) and a roadmap for scientific data stewardship improvement or to provide data quality and usability information to users, stakeholders, and decision makers.

Medicinal mushrooms occurring in South India namely Ganoderma lucidum, Phellinus rimosus, Pleurotus florida and Pleurotus pulmonaris possessed profound antioxidant and antitumor activities. This indicated that these mushrooms would be valuable sources of antioxidant and antitumor compounds. Investigations also revealed that they had significant antimutagenic and anticarcinogenic activities. Thus, Indian medicinal mushrooms are potential sources of antioxidant and anticancer compounds. However, intensive and extensive investigations are needed to exploit their valuable therapeutic use.

A growing body of literature in the behavioral, ecological and pharmacological sciences suggests that animals use certain plants for the control of parasite infection and related illnesses. It has also become increasingly apparent that chimpanzees in Africa and their human counterparts share strong similarities in the plants they use for the treatment of similar diseases. Little is yet known, however, of the other closest living ape relative in Africa, the gorilla. Here we review the ethnopharmacological literature to evaluate the possible role of plant secondary compounds in the diet of gorillas in the wild. A total of 118 medicinal plant species from 59 families are listed from an extensive review of the literature on gorilla diet in the wild. The major pharmacological activities of those plant foods, which are also used in traditional medicine include antiparasitic, antifungal, antibacterial, antiviral, cardiotonic, hallucinogenic, stimulatory and respiratory activities. A greater understanding of the role of such plants in the primate diet and how these plants can be used for health maintenance is a promising new avenue for expanding our understanding of the biological basis and origins of traditional human medicinal practices and for developing novel applications of ethnopharmacological knowledge for humans.

An overview is presented of the many opportunities and challenges for using “Big Data” concepts to treat data from chemical sensors. Issues discussed include the need to make data machine readable and how to integrate distinct types of data that can be acquired and stored in different places. As a concrete example of possible applications, we propose a framework for an expert system dedicated to clinical diagnosis, where data from various types of sensors can be combined with text to provide better-informed diagnostics.

The effects of carbon content on tetragonality and magnetic moment of bcc iron have been evaluated by first-principles calculation. Three kinds of supercells, Fe54C1, Fe54C2 and Fe128C1 (which correspond to Fe-0.40C, Fe-0.79 and Fe-0.17C mass%, respectively) are used for the calculation of tetragonality and magnetic moment of Fe-C system. Main results obtained are as follows. (1) The total energy and mechanical energy of the Fe-C system with carbon atom at the octahedral sites are smaller than those with carbon atom at the tetragonal sites. The carbon atom at octahedral site produces fairly large expansion in one direction. (2) Tetragonality of Fe-C system obtained by first-principles calculation increases linearly with increasing carbon content and agrees well with experimental results. The average magnetic moment of an Fe atom increases with increasing carbon content. (3) The magnetic moment of an Fe atom at the nearest neighbor of carbon atom is lower than that of pure iron and increases with increasing distance between the iron and carbon atoms. The projected density of states shows a hybridization with main contributions from Fe d and C p states which leads to the above mentioned decrease of the magnetic moment of an Fe atom. (4) In Fe54C2, tetragonality and magnetic moment of iron atom change with the distance between two carbon atoms. The value of tetragonality is either 0.981, 1.036 or 1.090. When the dumbbell structure which consists of the first carbon atom and its two nearest neighbor iron atoms is perpendicular to the second dumbbell structure which consists of the second carbon atom and its two nearest neighbor iron atoms, the tetragonality is 0.981 and does not agree with experimental value. The mechanical energy is relatively large. On the other hand, when the first dumbbell structure is parallel to the second dumbbell structure, the tetragonality is 1.036 which agrees well with experimental data. The mechanical energy is relatively small. When straight C-Fe-C pair is formed, tetragonality is 1.090. (5) In Fe54C2, formation enthalpy is relatively low when the calculated tetragonality is 1.036, and the existence probability under the assumption of Boltzmann distribution is high. In other cases, the existence probability is nearly zero. (6) The average magnetic moment of an Fe atom is proportional to volume, but not in a clear relation with tetragonality. It is considered that the increase of magnetic moment of an Fe atom by the addition of carbon atom is mainly due to the magneto-volume effect but not due to the tetragonality effect.
