Tetrapod, one of the well-known artificial concrete units, is frequently used as an armor unit on breakwaters. Two layers of tetrapod units are normmaly placed on the breakwaters with different placement methods. In this study, the stability of tetrapod units with two different regularly placement methods are investigated experimentally in irregular waves. Stability coefficients of tetrapod units for both placement methods are obtained. The important characteristic wave parameters of irregular waves causing the same damage ratio as those of the regular waves are also determined. It reveals that the average of one-tenth highest wave heights within the wave train （H1/lo） causes the similar damage as regular waves.

OBJECTIVE:To evaluate school success in pediatric patients undergoing acupuncture treatment for ***: The grades achieved during both school terms by children undergoing acupuncture treatment for various indications at the pediatric out patient clinic of Ulus State Hospital were analyzed. Exam grades in mathematics, social studies,and Turkish was compared between the first and the second terms. Forty children were included in thestudy,with 22 male and 18 female,and their average age was 11.1 years. These patients were undergoing acupuncture treatment for attention deficit-hyperactivity disorder(ADHD), enuresis nocturna, migraine, obesity, atopic dermatitis, alopecia areata, and Tourette's syndrome. Treatments were done at the beginning of the second term. Four of the 25 patients with ADHD had borderline intelligence *** report cards of all 40 patients were examined, and their grades in the first and these condschool term were ***: There was a statistically significant increase in the grades obtained in mathematics, social studies, and Turkish(P<0.005) by the students from the first to the second school term. When 4 ADHD patients with borderline deficiency in intelligence were excluded, and the grades among the 21 patients with ADHD were compared for both terms, there was also a statistically significant increase in mathematics, social studies, and Turkish grades(P<0.05).CONCLUSION: Acupuncture contributed to the academic success of the children who under went acupuncture treatment for their primary symptoms.

Lichens are widely used in biomonitoring studies of air pollution, either as bioindicators of air quality or as bioaccumulators of atmospheric deposition. Over the past decade, several molecular techniques have been developed to provide information on diversity, genotoxicology, genetic relationships, etc. The heavy metal contents of Evernia prunastri samples were determined by atomic absorption spectrometry. The Random Amplified Polymorphic DNA Polymerase Chain Reaction （RAPD-PCR） method was used to describe the pattern of DNA band variation in the samples influenced by the environmental pollution. The study was designed to describe the level of pollution in an area contaminated with smoke and waste from an iron-steel factory, and to reveal the level of potential genotoxic agents around this source of pollution. The study also examined the suitability of the lichen samples for the detection of genotoxicity.

A series of N-（5-chloro-2-hydroxyphenyl）-（3/4/5-substituted）-salicylaldimines （I--XI） were synthesized using appropriate synthetic route. Their structures were characterized by FT-IR, UV-Visible, ESI-MS, 1H and 13C NMR spectroscopic techniques and analytical methods. The crystal structure of N-（5-chloro-2-hydroxyphenyl）-5-bromo- salicylaldimine （V） was determined by X-ray diffraction at room temperature. Relationship between the melting points and the structures of the compounds was examined. Antimicrobial activity of the compounds was evaluated against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus mirabilis. Antifungal activities were reported for Candida albicans. Schiff bases showed considerable antimicrobial activity against S. aureus, S, epidermidis and C. albicans. N-（5-Chloro-2-hydroxyphenyl）-3-hydroxy-salieylaldimine （II） has the broadest and highest antimicrobial activity according to the others.

Fetal cells can enter maternal blood during pregnancy but whether they can also cross the blood-brain barrier to enter the maternal brain remains poorly understood. Previous results suggest that fetal cells are summoned to repair damage to the mother＇s brain. If this is confirmed, it would open up new and safer avenues of treatment for brain damage caused by strokes and neural diseases. In this study, we aimed to investigate whether a baby＇s stem cells can enter the maternal brain during pregnancy. Deceased patients who had at least one male offspring and no history of abortion and blood transfusion were included in this study. DNA was extracted from brain tissue samples of deceased women using standard phenol-chloroform extraction and ethanol precipitation methods. Genomic DNA was screened by quantitative fluorescent-polymerase chain reaction amplification together with short tandem repeat markers specific to the Y chromosome, and 13, 18, 21 and X. Any foreign DNA residues that could be used to interpret the presence of fetal stem cells in the maternal brain were monitored. Results indicated that fetal stem cells can not cross the blood-brain barrier to enter the maternal brain.

The aim of this study was to investigate proton magnetic resonance spectroscopy metabolite values in the medial prefrontal cortex of individuals with euthymic bipolar disorder. The subjects consisted of 15 patients with euthymic bipolar disorder type I and 15 healthy controls. We performed proton magnetic resonance spectroscopy of the bilateral medial prefrontal cortex and measured levels of N-acetyl aspartate, choline and creatine. Levels of these three metabolites in the medial prefrontal cortex were found to be lower in patients with bipolar disorder compared with healthy controls. A positive correlation was found between illness duration and choline levels in the right medial prefrontal cortex. Our study suggests that during the euthymic period, there are abnormalities in cellular energy and membrane phospholipid metabolism in the medial prefrontal cortex, and that this may impair neuronal activity and integrity.
