Ontology‐supported polarity mining
Authors: Zhou Lina , Chaovalit Pimwadee 
Published: October 2007

AbstractPolarity mining provides an in‐depth analysis of semantic orientations of text information. Motivated by its success in the area of topic mining, we propose an ontology‐supported polarity mining (OSPM) approach. The approach aims to enhance polarity mining with ontology by providing detailed topic‐specific information. OSPM was evaluated in the movie review domain using both supervised and unsupervised techniques. Results revealed that OSPM outperformed the baseline method without ontology support. The findings of this study not only advance the state of polarity mining research but also shed light on future research directions.
O‐Alkyl S‐3,3‐Dimethyl‐2‐oxobutyl Dithiocarbonates as Versatile Sulfur‐Transfer Agents in Radical C(sp3)H Functionalization
Authors: Sato Akinori , Yorimitsu Hideki , Oshima Koichiro 
Published: October 2007

AbstractBoiling of the title compounds in ethereal solvents or cycloalkanes in the presence of a radical initiator leads to radical C(sp3)H functionalization, by which a sulfur atom is introduced into the ethereal solvents at the oxygenated carbon atom or into the cycloalkanes. Both acyclic and cyclic ethers, such as [18]crown‐6 and [D8]THF, undergo the sulfur transfer. The reaction is useful for the synthesis of monothioacetals, thiols, and sulfides from simple starting materials.
Exposure to extremely low frequency magnetic fields affects insulin‐secreting cells
Authors: Sakurai Tomonori , Yoshimoto Miwa , Koyama Shin , Miyakoshi Junji 
Published: October 2007

AbstractTo evaluate the effects of extremely low frequency magnetic field (ELFMF) on β‐cell survival and function, we cultured a hamster‐derived insulin‐secreting cell line (HIT‐T15), which exhibits responsiveness to glucose in a semi‐physiological range, under exposure to sham and ELFMF conditions, and assessed cell survival and function. We used our previously developed ELFMF exposure unit (a sinusoidal magnetic field at a frequency of 60 Hz, 5 mT) to culture cells under exposure to ELFMF conditions. We found that exposure to ELFMF for 5 days in the absence of glucose increased cell number, exposure for 2 days in the absence of glucose and for 5 days with 100 mg/dl glucose increased the insulin secretion to the culture medium, and exposure for 2 and 5 days with 40 and 100 mg/dl glucose increased intracellular insulin concentration in HIT‐T15 cells. The increase in cell number under apoptotic culture conditions by exposure to ELFMF could lead to new therapeutic concepts in the treatment of diabetes. The ELFMF‐induced increase in intracellular insulin concentration could be utilized to develop culture conditions to enhance intracellular insulin concentration in insulin‐secreting cells that would be useful for cell transplantation to cure diabetes mellitus.

Electromagnetic field measurements using personal exposimeters
Authors: Knafl Urs , Lehmann Hugo , Riederer Markus 
Published: October 2007

AbstractThe goal of this brief communication is to call the attention of researchers to possible pit falls when using personal exposimeters (PEM) in epidemiological field studies. One example of problematic handling of PEMs is presented in detail, whereas other possible error sources and other aspects to be considered using such devices are outlined only briefly.

Fate of the non-operated, non-toxic goitre in a defined population
Authors: Winbladh A , Järhult J 
Published: October 2007

Abstract

Background
There is lack of consensus in Europe regarding the management of patients with benign goitre. This study evaluated the long-term results of recommending no surgery for clinically and cytologically benign goitre.

Methods
Some 261 patients (median age 56 years) referred for surgical evaluation for goitre were followed prospectively for a median of 130 months. All hospital and primary care charts were reviewed and living patients interviewed by telephone.

Results
During follow-up, 36·4 per cent of patients were re-referred for a new surgical evaluation, mainly because of growth of the goitre and/or worsening of local symptoms. Fifty-seven (21·8 per cent) of the patients had surgery, and 13 developed thyrotoxicosis. Five patients (1·9 per cent) were diagnosed with thyroid carcinoma, three of whom (all elderly women) died from the disease. Some 95·0 per cent of patients were satisfied with the expectant policy, but 13·1 per cent had been worried about thyroid cancer despite the reassurance of a benign diagnosis.

Conclusion
Patients with benign goitre can be treated conservatively with good results. However, there is a small risk that aggressive carcinoma will develop and about a quarter of patients may need surgery within 10 years of the decision to wait and see.
Face‐to‐Face Pacman‐Type Porphyrin–Fullerene Dyads: Design, Synthesis, Charge‐Transfer Interactions, and Photophysical Studies
Authors: D'Souza Francis , Maligaspe Eranda , Karr Paul A. , Schumacher Amy Lea , El Ojaimi Maya , Gros Claude P. , Barbe Jean‐Michel , Ohkubo Kei , Fukuzumi Shunichi 
Published: October 2007

AbstractPacman‐type face‐to‐face zinc–porphyrin–fullerene dyads have been newly synthesized and studied. Owing to the close proximity of the donor and acceptor entities, strong π–π intramolecular interactions between the porphyrin and fullerene entities resulted in modulating the spectral and electrochemical properties of the dyads. New absorption and emission bands that correspond to the charge‐transfer interactions were observed in the near‐IR region. Time‐resolved transient absorption studies revealed efficient photoinduced electron transfer from the singlet excited porphyrin to the fullerene entity. The rate constants for photoinduced electron transfer are analyzed in terms of the Marcus theory of electron transfer, which afforded a large electron coupling matrix element (V=140 cm−1) for the face‐to‐face dyads. As a consequence of the large charge‐recombination driving force in the Marcus inverted region, a relatively long lifetime of the charge‐separated state has been achieved.
