The accumulation of organochlorines (OCs) in mussel tissue depends on the physiological and biochemical status of the organism and its interaction with the environment. Mytilus galloprovincialis, 2- and 1-year-old mussels, sampled from Mali Ston Bay, a reference area, and transplanted to Kaštela Bay in cages, were used for the assessment of OC levels and influence of biological parameters on accumulation. Results of bimonthly exposures during one year highlighted that OC accumulation decreases with increasing mussel age. Polychlorinated biphenyls (PCBs) and p,p′-dichlorodiphenyltrichloroethane (p,p′-DDTs) increased, while organochlorine pesticide (OCP; i.e., HCB, lindane, heptachlor, and aldrin) variations were very low. Statistical analysis generally did not confirm the significant effect of lipid content on the accumulation of OCs in mussel tissue. OC levels in mussels were below the maximum permitted levels for human consumption (European Commission).

Background: Many pediatric studies describe the association between biological parameters (BP) and severity of sickle cell disease (SCD) using different methods to collect or to analyze BP. This article assesses the methods used for collection and subsequent statistical analysis of BP, and how these impact prognostic results in SCD children cohort studies. Methods: Firstly, we identified the collection and statistical methods used in published SCD cohort studies. Secondly, these methods were applied to our cohort of 375 SCD children, to evaluate the association of BP with cerebral vasculopathy (CV). Results: In 16 cohort studies, BP were collected either once or several times during follow-up. The identified methods in the statistical analysis were: (1) one baseline value per patient (2) last known value; (3) mean of all values; (4) modelling of all values in a two-stage approach. Applying these four different statistical methods to our cohort, the results and interpretation of the association between BP and CV were different depending on the method used. Conclusion: The BP prognostic value depends on the chosen statistical analysis method. Appropriate statistical analyses of prognostic factors in cohort studies should be considered and should enable valuable and reproducible conclusions.

Nutritional Components

In Vietnam, the giant mottle eel Anguilla marmorata is the most widely distributed species and being exploited for seed in aquaculture as well as for human consumption. This study aims to investigate the basic nutritional components of the fish. The eels were collected from six locations of Thua Thien Hue province, with weights from 5 to 3200 g. In addition, the content of lipid in skin and tissue was also examined. The results show that eel flesh has a relatively high nutritional value. The water, protein, lipid, and total sugar content of the fish meat is 60.4 ± 0.94%, 19.54 ± 4.31%, 18.2 ± 1.02%, and 1.34 ± 0.34 (mg/g), respectively. The nutritional components of the eel have a good correlation with the weight according to the equation: Y = a × ln (W) + b (where W is the weight of eels; Y is the content of nutritional components; a is the correlation coefficient b is a constant) with r > 0.9. The lipid content of the fish skin is higher than that of muscle and meat.

Background and Aim: Major depression in both women and men is a debilitating disorder that disrupts relationship and daily lives and affects nearly 10% of general populations. The aims and objectives of this study were to determine the gender differences in major depression with respect to following: Demographic characteristics, Clinical manifestations, Stressful life events, Risk factors. Materials and Methods: Total of 100 patients was included in the study. All the included patients meet the criteria for DSM-IV (Diagnostic and Statistical Manual of Mental Disorders) diagnosis of major depression. The included patients were interviewed at the department of Psychiatry, B. J. Medical College & civil hospital Ahmedabad. Based on the Life Events Scale by Holmes and Rahe (1967), its Indian adaptation PSLE (Presumptive stressful life events scale) was done by Gurmeet Singh (1983). The statistical analysis was done by using SPSS IX version. Results: Their ages range from 18 to 70 years. Most of the patients were married, were from urban background, and nuclear family. On Hamilton Depression rating scale when the statistical analysis was done, there was no significant difference between males and females. Men had higher mean life events score than women but this was not statistically significant. In female, there was significant positive correlation between number of life events in one year and severity of depression as well as impact score during one year prior to onset of depression and Hamilton rating scores. Conclusion: Male and female major depression patients did not differ as regards demographic characteristics, except that most women were homemakers and men were employed. Number of stressful life events experienced during 1 year prior to onset of MDD was similar. Early insomnia, middle insomnia and somatic symptoms general were more severely present in female patients.

One of the major issues that we can observe as a trend; also, the constituent considers it as a criminal act is “SUICIDE”. The scope of this research covers the statistical analysis of the recent trends in suicidal activity in various states of India. Section 306 of IPC (Indian Penal Code) covers this crime and states “Whoever attempts to commit suicide and does any such activity towards the commission of suicide, shall be punished with simple imprisonment for a term which may extend to one year or ne or both”. Although various governmental and non-governmental organisations continuously spreading awareness among people, but various reasons still dominating to result such crime to be happened. Following analysis is based on age groups, gender and region wise comparison to reveal the stats in the near past. This can be helpful for various studies further and can give an Idea regarding the act.

There is a treasure trove of hidden information in the textual and narrative data of medical records that can be deciphered by text-mining techniques. The information provided by these methods can provide a basis for medical artificial intelligence and help support or improve clinical decision making by medical doctors. In this paper we extend previous work in an effort to extract meaningful information from free text medical records. We discuss a methodology for the analysis of medical records using some statistical analysis and the Kohonen Self-Organizing Map (SOM). The medical data derive from about 700 pediatric patients’ radiology department records where CT (Computed Tomography) scanning was used as part of a diagnostic exploration. The patients underwent CT scanning (single and multiple) throughout a one-year period in 2004 at the Nagasaki University Medical Hospital. Our approach led to a model based on SOM clusters and statistical analysis which may suggest a strategy for limiting CT scan requests. This is important because radiation at levels ordinarily used for CT scanning may pose significant health risks especially to children.

Wheat is an important cereal in terms of human consumption in many countries of the world. It is grown mainly in arid and semi-arid Mediterranean countries. In these areas, salinity of soils and irrigation water is one of the limiting factors in plant productivity and agricultural yield. The present work consisted in evaluating the morpho-physiological and biochemical behavior of two durum wheat varieties V1 (Gta dur), V2 (Vitron) subjected to increasing concentrations of NaCl during the germination phase and the growth phase in the laboratory. The results obtained showed several revelations in terms of morphological imbalance (leaf area, germination percentage, root length, physiological variation, decrease or increase of assimilating pigments, Relative Water Content (RWC), etc), and biochemical bioaccumulation (proline, soluble sugars, proteins and elevation of activity of CAT antioxidant enzymes). At the level of treatments, the development of the seedlings of two varieties was better on soil salty and sprinkled with water than in the presence of saline concentrations. A certain tolerance of the two genotypes was particularly marked in the Vitron variety against salt stress.

Power Generation Performance

Traditionally, studies on the power generation performance analysis of the photovoltaic (PV) modules used in building-integrated PV (BIPV) systems have been based on computer simulations and actual experiments with constraints, resulting in the results being inaccurate and limited. This paper proposes a two-step analysis method that results in a more versatile and reliable means of analysis. The steps are: (1) construction of a mock-up test building in the form of BIPV systems and the collection of a massive amount of operational data for one year; and (2) a statistical analysis of the acquired data using Minitab software (Version: 17, Manufacturer: Minitab Inc., State College, PA, USA) to examine the power generation performance. The constructed BIPV mock-up applies design elements such as material types (c-Si and a-Si) and various directions and angles for different module installations. Prior to the analysis, the reliability of the large database (DB) constructed from the acquired data is statistically validated. Then, from the statistical correlation analysis of the DB, several plots that visualize the performance characteristics governed by design elements, including contour plots that show the region of higher performance, are generated. Further, a regression model equation for power generation performance is derived and verified. The results of this study will be useful in determining whether a BIPV system should be adopted in a building’s architectural design and, subsequently, selecting design element values for an actual BIPV system.
