Of the most popular applications of artificial intelligence (AI), those used in the health sector are the ones that represent the largest proportion, in terms of use and expectation. An investigative systematization model is proposed in the scientific training of nursing professionals, by articulating epistemological positions from previous studies on the subject. In order to validate the model proposed, a prototype was created to present an application that could help nurses in their clinical processes, storing their experiences in a case base for future research. The prototype consisted of digitizing paediatric nursing diagnoses and inserting them into a case base in order to assess the effectiveness of the prototype in handling these cases in a structure conducive to retrieval, adaptation, indexing, and case comparison. This work presents as a result a computational tool for the health area, employing one of the artificial intelligence techniques, case-based reasoning (CBR). The small governmental nursing education institution in Bangladesh used in this study did not yet have the systemization of nursing care (NCS) and computerized support scales.

Heavy metals are known to cause deleterious effects on human health through food chain. Human health risks were evaluated from consumption of heavy metal contaminated fish from Buriganga River in Bangladesh. Whole body of five fish species (Puntius ticto, Puntius sophore, Puntius chola, Labeo rohita and Glossogobius giuris) were analyzed which contained various concentrations of Cd, As, Pb, Cr, Ni, Zn, Se, Cu, Mo, Mn, Sb, Ba, V and Ag. Concentrations of Mn, Zn, Se and Pb in all fish species were above the Food Safety Guideline (FSG) by WHO/FAO. Assessment of noncarcinogenic health hazard by target hazard quotient (THQ) indicated no concern from consumption of these fish except for Mn. However, all metals together may affect human health as revealed by hazard index (HI). The target cancer risk (TR) values suggested carcinogenic risk from Ni and As. Taken together it can be concluded that there is potential human health risk in consuming fish from river Buriganga.

The present study was undertaken to explore the effect of administration of high doses of sodium selenite on the apoptosis of lymphoma cells in patients with non-Hodgkin's lymphoma (NHL). Forty patients with newly diagnosed NHL were randomly divided into two groups. Group I received standard chemotherapy, whereas group II received adjuvant sodium selenite 0.2 mg kg(-1) day(-1) for 7 days in addition to chemotherapy. Flow cytometry was used for monitoring of lymphoma cells apoptosis at the time of diagnosis and after therapy in the two groups. Sodium selenite administration resulted in significant increase in percentage of apoptotic lymphoma cells after therapy in group II (78.9 +/- 13.3% versus 58.9 +/- 18.9%, p < 0.05). In addition, patients who received sodium selenite treatment demonstrated statistically significant increase in percentage of reduction of cervical and axillary lymphadenopathy, decrease in splenic size, and decreased percentage of bone marrow infiltration. Also, we found a statistically significant decrease in cardiac ejection fraction (CEF) in group I and no reduction in CEF in patients who received sodium selenite 'group II', denoting the cardioprotective effect of selenium. It is concluded that sodium selenite administration at the dosage and duration chosen has synergistic effect to chemotherapy in inducing apoptosis and, consequently, could improve clinical outcome.

This experiment was conducted to study the effect of different environments on rearing and production performance of freshwater mud eel, Monopterus cuchia. The study was conducted over a period of six months from June to November 2013. Different environments such as House tanks, Earthen ditches, Plastic tank and Back yard tanks were used. Except the earthen ditch-2 (control), all environments were fed by different biological food such as small live fish (Tilapia fry), earth worms, small dead fish, snails, small frogs and chicken viscera in different amounts. 40 fishes (approximately 1kg in weight) were stocked into each of the environment. At the end of the experiment, the highest mean of final length (32.89±2.65423) and final weight (109.69±2.92777) were obtained in earthen ditch-1. The weight gain in length 17.78 ± 0.24 and in weight 85.07 ± 0.15 with 92.5% survival and production (4.07kg) were also highest in earthen ditch-1. However, earthenditch-2 which was used as control has also shown satisfactory results in terms of weight gain in length and weight 14.1 ± 0.48 and 66.66 ± 0.82 respectively with 87.5% survival. On the other hand, the lowest mean growth considering final length (28.45±2.80092) and weight (67.24±3.79328) were recorded in house tank-2 while the weight gain in length (11.86 ± 0.26) and in weigh (41.84 ± 0.59) were also observed in house tank-2 with the production of 2.02kg by 75% survival. Based on Pearson Correlation coefficient there were no significant correlations between lengths and weights of fish in different culture regimes. Significant value (P=0.000) of each of the environments implies that M. cuchia can be reared significantly except back yard tank-1 (P=0.009). But, in case of earthen ditch-1 the highest value was found in both length and weight with 5% significance level due to supplied live feeds. On the basis of the better growth, survival and production, it is suggested that the earthen ditch is one of the suitable culture environments of M. cuchia. From this study, it was also found that the live feed are suitable for obtaining highest growth performance based on the findings of plastic tank, house tanks 1 and house tank 3.
