ABSTRACTFingernails from several sources were studied to determine elemental compositions. The common elements were found to be H, C, N, O, Ca and Fe. The elements Si, Bi, S, Mo, Ti, Zn, Pb, P and Nd were found on some of the nails; these are considered to result from environmental contamination, food and water intake. The compositions of H, C, N and O correlate with those in the hemoglobin molecule and, they do not vary significantly with time. This suggests that they are associated with dead blood cells. The other common elements, such as Ca and Fe, show variations in composition with time, probably because their amount in the body is determined by food and water intake. Fingernails from female sources have a higher concentration of Ca than those from male sources. Also, the concentration of Ca is generally higher on the outer than the inner surface of the nail, probably to provide a stronger bony structure and mechanical strength on the outside.

AbstractThe question of effects of long-term melatonin (MEL) administration have not yet been explained sufficiently, especially its metabolic consequences in young persons and animals. The aim of the present study was to analyze the effects of MEL given during prolonged time (for 3 months) and chronically (for 6 months) at the dose of 4 µg/mL of tap water, on the selected metabolic and hormonal parameters in young female and male Wistar:Han (WH) rats. The weights of selected organs, tissues, body weight gains and food and water intake were registered. Six weeks aged rats were adapted to standard housing conditions and light regimen L:D=12:12 h, fed standard laboratory diet and drank tap water (controls) or MEL solution ad libitum; finally they were sacrificed after overnight fasting. Prolonged MEL administration decreased serum glucose concentration and increased triacylglycerol and malondialdehyde concentration/content in the liver in females. In males MEL increased concentrations of serum phospholipids, corticosterone and liver malondialdehyde. MEL treatment reduced the body weight in both sexes and weight of epididymal fat in males, without any alterations of food and water intake. Chronic MEL administration reduced serum glucose concentration and increased concentration/content of glycogen, triacylglycerol and cholesterol in the liver and glycogen concentration/content in heart muscle in males. In females, the significant rise of serum corticosterone concentration and liver malondialdehyde content was recorded. MEL significantly increased liver weight and decreased thymus weight in males. MEL administration increased temporarily water intake in males, body and epididymal fat weights were similar to that in controls. Body weight of MEL drinking females was reduced in the 1st half of experiment only; the food and water intake did not differ from control group. The response in WH rats on MEL was more prominent as in the Sprague-Dawley strain (our previous studies). Male rats were generally more affected, probably due to higher daily and total consumption of melatonin.

Natural multiped gaits are believed to evolve from countless generations of natural selection. However, do they also prove to be better choices for walking machines? This paper compares two surefooted gaits, one natural and the other artificial, for six-legged animals or robots. In these gaits four legs are used to support the body, enabling greater stability and tolerance for faults. A standardized hexapod model was carefully examined as it moved in arbitrary directions. The study also introduced a new factor in addition to the traditional stability margin criterion to evaluate the equilibrium of such gaits. Contrary to the common belief that natural gaits would always provide better stability during locomotion, these results show that the artificial gait is superior to the natural gait when moving transversely in precarious conditions.

The writer looks at the meanings of the word ‘play’ and its properties, and draws attention to the common elements and the differences to be observed in the play of young people and adults respectively. He applies these observations to music, giving examples.He then considers how classroom teachers have used some of the ‘play’ principles in their work, and introduces the idea of drawing instrumental teachers into similar patterns of action – to be fully developed in the other articles in this group. He summarises recent writings on the subject and his own practical contributions over the last few years.

Whether we consider the astonishing subtlety of that medium, which renders visible to us objects existing at the most immeasurable distances from us, or that delicately constituted organ which, by its general structure, collects the rays of light, and by a nice adaptation of its parts concentrates their force on the sentient fibres of the retina, expanded over its inner surface, we can feel no surprise that such great talents should have been devoted to investigate the curious properties of the one, or that the structure of the other should have been examined with so much assiduity. The keenness of inquiry manifested by the cultivators of anatomy in observing the most minute parts that have escaped the notice of their predecessors, shows that any addition to the common stock of our information on this subject will be gratifying to a certain portion of the members of this Society, and probably not uninteresting to the Society at large.

Diseases that cause anemia are very diverse, and therefore it is very difficult to classify anemias according to their etiology, and due to various constitutional and other characteristics of the organism, the same cause can cause different phenomena. It is easier to approach the question of the cause of anemia by determining whether erythropoiesis suffers from this disease or whether there is an increased breakdown of red blood cells. In the body, the state of the blood is composed of two processes: on the one hand, erythropoiesis, on the other hand, the decay of erythrocytes. Demonstrative formula Yerringer'a E R D (Blutmauserung), where E is the number of erythrocytes, P is their production and D ~ destruction. As long as P balances M, the difference E. remains unchanged. If D, that is, hemolysis, increases more than P, then we get a hemolytic type of anemia. If D hemolysis remains unchanged, but P decreases we get an aplastic type of anemia.

The structural features of the esophagus, proventriculus and ventriculus of 4 chicken and duck carcasses were studied using the common anatomical dissection method. It is noted that the esophagus is a thin-walled, easily expandable tube, linking the pharynx to the proventriculus. It is subdivided into the cervical and thoracic regions. The length of the esophagus depends on the length of the neck. In a duck, it is 28.29 cm, in a chicken – 25.3 cm. In a hen that has a crop, there is a pre-and post-crop part. The feed swells and moistens in the crop. Ducks has a spindle-shaped crop, which is weakly developed. There is an esophagus opening in the proventriculus; the body, the top, the bottom and the intermediate zone of proventriculus are distinguished. The mucous membrane is formed in cellular folds, which are longitudinal, shriveled, with clearly visible papillae in the chicken, and in the duck they are flat. In the submucosal layer there are digestive glands that secrete mucus, enzymes and hydrochloric acid. The ventriculus consists of the body, the greater and lesser curvatures, the cranial and caudal grooves. It performs grinding of feed, and it is the largest organ of the digestive system due to the thick muscular wall. The inner surface of the ventriculus is covered with cuticle – a coarse, thick, non-tensile membrane that protects the mucosa from damage by solid food particles and from the effects of digestive juice.

Paleontological Study

      Mukdadiya Formation represents one of the formations that cover a huge area of Iraq. It contains several clastic deposits, such as sandstone, siltstone, and a noticeable amount of gravels. The gravels are considered as the hallmark to differentiate between Injana and Mukdadiya formations. Therefore, the current study focused on these facies to determine the petrography, paleontology , and origin of Mukdadiya deposits. The results of SEM-EDX and XRD analyses showed two types of gravels, namely the siliceous and lime gravels. The highest percentage of gravels belonged to the sedimentary origin (limestone). The elements of Si, Ca, and Fe represented the common elements that formed the studied gravels. The paleontological study displayed numerous fossils that are composed of these gravels, belonging to several groups, including foraminifera, radiolaria, dinoflagellata, echinoida, gastropoda, and calcisphera.  Also, four microfacies were identified in the studied gravels. After comparison of all collected data with selected formations, the results confirmed that the origin of the derived gravels is from the Qulqula Formation, because of their content of radiolaria and the other characterizing fossils.

Background: The mandible is the strongest and largest bone of facial skeleton. It consists of one horseshoe-shaped body and a pair of rami. On external surface of body in the midline there is a faint ridge i.e. symphysis menti indicating the line of fusion of two halves of mandible during development. The aim of this study is to describe the position and incidence of accessory foramina on the inner surface of the body and rami of both sides of mandible to provide simple important reliable surgical landmarks.Methods: The present study was conducted on 100 dried adult human mandibles. Bones which had deformities, asymmetries, external pathological changes and fractures were excluded from the present study.Results: In 97% cases at least one accessory foramen was observed on inner surface of mandible. The accessory lingual foramen was found to be constant finding with incidence of 81%. Frequency of infraspinous or sublingual foramen was 58%, of lateral foramen was 50% and that of accessory mandibular foramen was 39%.Conclusions: The anatomical knowledge about the common location and incidence of accessory foramina in mandible are important for surgeons and anaesthetists performing surgeries in the area around mandible. These accessory foramina transmit neurovascular bundles which provide accessory innervations to the roots of teeth.  Thus proper knowledge of accessory foramina are important in relation to achieving complete inferior alveolar nerve block and for avoiding injury to neurovascular bundle passing through them.

In this paper, the potential antidote efficacy of commercially available formulations of various feed additives such as Minazel-Plus®, Mycosorb®, and Mycofix® was considered by recording their incidence on general health, body weight, and food and water intake, as well as through histopathology and semiquantitative analysis of gastric alterations in Wistar rats treated with the T-2 toxin in a single-dose regimen of 1.67 mg/kg p.o. (1 LD50) for 4 weeks. As an organic adsorbent, Mycosorb® successfully antagonized acute lethal incidence of the T-2 toxin (protective index (PI) = 2.25; p < 0.05 vs. T-2 toxin), and had adverse effects on body weight gain as well as food and water intake during the research (p < 0.001). However, the protective efficacy of the other two food additives was significantly lower (p < 0.05). Treatment with Mycosorb® significantly reduced the severity of gastric damage, which was not the case when the other two adsorbents were used. Our results suggest that Mycosorb® is a much better adsorbent for preventing the adverse impact of the T-2 toxin as well as its toxic metabolites compared with Minazel-plus® or Mycofix-plus®, and it almost completely suppresses its acute toxic effects and cytotoxic potential on the gastric epithelial, glandular, and vascular endothelial cells.

Acceleration Signals

Abstract:In this study, we attempted to discriminate the acceleration signal for horizontal level and stairway walking using wavelet-based fractal analysis method. The acceleration signal was measured close to the center of gravity of the body, while the subjects walked continuously in the corridor and up and down the stairs. We used the wavelet-based fractal analysis method to discriminate walking pattern. The parameter H which is related directly to the fractal dimension was estimated by the wavelet coefficient and was changed into low value during walking upstairs. By manually setting the threshold level for individual, it was possible to discriminate walking upstairs from the other walking type. However, the common feature among subjects was not shown between level walking and walking downstairs.
