TL;DR: Lack of antenatal care, primiparity, and failure to have chemoprophylaxis against malaria were the maternal factors found to be associated with placental malaria infection.
Abstract: The objective of this study was to determine the role of malaria in the etiology of fetal malnutrition in Nigeria. This study took place at the Neonatal and Maternity Units of the Wesley Guild Hospital, Ilesa, Nigeria. This is a prospective study of 304 consecutive, singleton, term live births delivered between January and August 2002. Anthropometric and clinical data were recorded. Fetal malnutrition (FM; failure to acquire adequate quantum of fat and muscle mass during intrauterine growth) was diagnosed using clinical assessment of fetal nutritional status (CANS) and the score (CANSCORE) adapted by Metcoff. The placenta tissues were examined for malaria pigments and parasites, and placental and cord blood smears were examined for parasites. Babies were followed up in the neonatal period for clinical malaria. Babies were grouped into those with malaria-infected placental and cord blood specimens and those without. The two groups were compared with regard to the proportions with FM and complications of FM. Three hundred four placental and cord blood specimens were examined for malaria. Of the 304, 101 (33.2%) of the placental and 67 (22.0%) of the cord blood specimens were positive for malaria. Sixty-six (21.7%) of the 304 babies had FM. Forty-four (66.7%) of the 66 placental blood specimens of babies with FM were positive for malaria, whereas 57 (24.0%) of the 238 placentae of babies without FM had placental malaria ( 2 42.5, P < 0.0001). Similarly, 27 (40.9%) of 66 babies with FM compared with 40 (16.8%) among 238 babies without FM had malaria parasites in the cord blood ( 2 17.5, P < 0.001). The means of birth weight, ponderal index, and placenta weight were significantly lower among the babies of mothers with malaria-infected placentae than those without (P < 0.05 in all cases). Lack of antenatal care, primiparity, and failure to have chemoprophylaxis against malaria were the maternal factors found to be associated with placental malaria infection. Placental malaria is a major factor in the etiology of FM in Nigeria.

TL;DR: In this article, the effects of three preparation variables: CO2 activation temperature, CO 2 activation time, and KOH: char impregnation ratio (IR) were studied using Response Surface Modeling (RSM).
Abstract: This work investigates both batch and optimization studies of adsorption of Remazol Brilliant Blue Reactive (RBBR) dye onto activated carbon prepared from periwinkle shells (PSAC). The effects of three preparation variables: CO2 activation temperature, CO2 activation time, and KOH: char impregnation ratio (IR) were studied using Response Surface Modeling (RSM). Based on the central composite design (CCD), a quadratic model and two-factor interaction models (2FI) were developed to correlate the three preparation variables to the two responses: RBBR dye removal and PSAC yield. The optimum conditions for preparing PSAC for adsorption of RBBR dye were found as follows: CO2 activation temperature of 811°C, CO2 activation time of 1.7 h and IR of 2.95, which resulted in 82.76% of RBBR dye removal and 35.83% of PSAC yield. Experimental results obtained agreed satisfactorily well with the model predictions. The activated carbon prepared under optimum conditions was mesoporous with BET surface area of 1894 m2/g, to...

TL;DR: This work is aimed at providing a neuro- fuzzy system for heart attack detection with eight input field and one output field that was designed in a way that the patient can use it personally.
Abstract: This work is aimed at providing a neuro- fuzzy system for heart attack detection. Theneuro-fuzzy system was designed with eight input field and one output field. The input variables are heart rate, exercise, blood pressure, age, cholesterol, chest pain type, blood sugar and sex. The output detects the risk levels of patients which are classified into 4 different fields: very low, low, high and very high. The data set used was extracted from the database and modeled in order to make it appropriate for the training, then the initial FIS structure was generated, the network was trained with the set of training data after which it was tested and validated with the set of testing data. The output of the system was designed in a way that the patient can use it personally. The patient just need to supply some values which serve as input to the system and based on the values supplied the system will be able to predict the risk level of the patient.

TL;DR: The particles inhibited the growth of multi-drug resistant clinical isolates of Escherichia coli, Klebsiella pneumoniae and Proteus vulgaris, and also potentiated the activities of ampicillin, ciprofloxacin and cefuroxime in the AgNPs-antibiotic synergy studies.
Abstract: Cell-free extracts of six strains of Enterococcus species obtained from fermented foods were used for the green synthesis of silver nanoparticles (AgNPs), which was characterized by UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). The biosynthesized AgNPs were dark brown in colour having surface plasmon resonance in the range of 420-442 nm. The spherical shaped AgNPs had sizes of 4-55 nm, whose formations were facilitated by proteins as indicated by the presence of peaks 1,635-1,637 and 3,275-3,313 cm -1 in the FTIR spectra. The energy dispersive x-ray (EDX) showed prominent presence of silver in the AgNPs colloidal solution, while the selected area electron diffraction was typified by the face-centred crystalline nature of silver. The particles inhibited the growth of multi-drug resistant clinical isolates of Escherichia coli, Klebsiella pneumoniae and Proteus vulgaris, and also potentiated the activities of ampicillin, ciprofloxacin and cefuroxime in the AgNPs-antibiotic synergy studies. In addition, the prospective relevance of the particles as nanopreservative in paints was demonstrated with the inhibition of growth of Staphylococcus aureus , Pseudomonas aeruginosa , Aspergillus niger and A. flavus in AgNPs-paint admixture . This report further demonstrates the green synthesis of AgNPs by strains of Enterococcus species.
