Elevated radioactivity levels of 226Ra, 232Th, and 40K in building materials were measured using gamma-ray spectrometry and their associated lifetime cancer risks were also determined. The mean activity concentrations of 226Ra, 232Th, and 40K are 45.72 ± 0.55, 65.90 ± 8.89, and 487.32 ± 15.20 Bq kg−1, respectively. Statistically, the principal component (PC) analysis indicates that higher loadings were recorded in Principal Component One (PC1) with large contribution from 232Th and 40K. The leverage studies indicate that BN Ceramics (BNC) contributes more to the loadings in PC1 followed by Golden Crown Ceramic (GCC) sample. The mean values of 0.399 mSv y−1 do not surpass the world average value of 0.7 mSv y−1. The mean gamma index from the measured samples is 0.644, whereas a mean value of 0.271 for alpha index is noted in the samples. The activity utilization index (AUI) from the samples satisfied the AUI <2, which corresponded with the annual effective dose of <0.3 mSv y−1, except interlock Site 2 and Gomez Spain tiles. Significantly, the mean value of excess lifetime cancer risk of 0.0014 is slightly lower than the world average value of 0.29 × 10−3. [ABSTRACT FROM AUTHOR]

The consumption of water with elevated concentration of lead (Pb) can prevent Hemoglobin Synthesis (Anemia) and results in Kidney diseases. A cross sectional study was conducted in to estimate the risk of exposure to lead via groundwater and bottled water ingestion pathway for the population of Covenant University, Canaanland, Ota, Ogun Sate using Perkin Elmer Optima 8000 ICP-OES. The concentration of Pb, Cr, Cd and As varies from water sample to another with the highest value of .7.07&3956;gL-1 was noted in borehole water sample (BH1) behind John Hall. Comparing the value with the International recommended level by USEPA and WHO respectively, 7.07gL-1is less than 15μgL-1 and 10&3956;gL-1. The Life Average Daily Dose (LADD) estimated in this present study reported higher in BH1 for lead (Pb) and could pose health hazard if accumulated for a long time. This work suggest measures to employ quality water treatment plant to reduce the level of heavy metals in the selected water samples and also more research on radioisotopes in the same water samples.

This study was conducted in order to estimate the carcinogenic risk of heavy metals exposure via the consumption of groundwater and bottled water for the population of Covenant University and Canaanland, Ota, Ogun state using Perkin Elmer Optima 8000 ICP-OES. The chronic daily intake (CDI) in all the samples ranged from 0.005 and and 0.014μgL-1kg-1d-1which was found to be negligible of potential risk on the inhabitants of different age groups. The carcinogenic Risk (R) for all the samples ranged between 0.01 and 0.025 μgL-1d-1. The R for all the age groups was found to be less than the acceptable level of EPA. The highest carcinogenic risk in Arsenic was found in children, which could be attributed to their lower body weight. However, all the values measured were observed to be below the recommended level by USEPA and WHO respectively. [ABSTRACT FROM AUTHOR]

Coagulation disorders that occur during surgery are more common than you think, so today anesthesiologists and physicians responsible for the Intensive Care Units (Intensivists) had an increased concern for acquired coagulopathy in critically ill patients who are in the immediate postoperative period. Disseminated intravascular coagulation is mainly due to an excessive and uncontrolled production of thrombin, triggered by various stimuli resulting from an imbalance between the activation and inhibition of the coagulation system and a delayed removal of degradation products of the coagulation. These phenomena lead to systemic intravascular fibrin deposition. The diagnosis is complex bearing in mind the variety of its pathophysiology and the key is specific and vigorous treatment of the underlying condition and in parallel intravascular volume must be replaced with necessary colloid and crystalloid blood products.
