The results obtained from heavy metal pollution assessment of River Ureje using Heavy Pollution Index (HPI) and Contamination Index (Cd ). HPI values at upstream and downstream point of the river, Cd, Pb, Cr had high pollution load that exceeded threshold value of 100 while Mn, Cu, Zn, Ni had low pollution index which are below threshold value. This indicated that high pollution status of Cd, Pb, Cr were observed because they compete with other essential metallic cations for binding sites and inhibits enzyme activity while there is no pollution presence of Zn, Mn, Ni, Cu. Cd value results in both upstream and downstream point revealed that Zn, Cd, Cu, Pb had a low contamination index below <1 contamination value and tends to show no effect on aquatic environment and drinking water quality. However, Cr, Ni had medium contamination compared to (Cd=1-3) Cd value, this indicates slight contamination of these heavy metals and have slight effect on drinking water quality and aquatic life present while Manganese had high Cd value compared to (Cd>3) Cd value which to tends have high effect on drinking water quality and aquatic system. In conclusions, this study revealed that High level of HPI above critical index value was observed for Cd, Cr, Pb while Mn shows high Cd far above contamination index value.

Introduction: Isavuconazole is an antifungal drug used for treating patients with invasive fungal infections. Efficacy and safety of isavuconazole is monitored by measuring plasma isavuconazole concentration using LCMS which is a non-affordable method. We used the HPLC system with a UV detector to measure plasma Isavuconazole concentration. Objective: Improved Reversed-phase high performance liquid chromatography procedure with UV detection is described which is cost effective, simple, precise and easily processed for the measurement of Isavuconazole, a drug used to treat the patients with invasive fungal infections, in blood plasma. Method: The method involves protein precipitation, addition of ammonium dihydrogen phosphate and chromatographic separation on a Hypurity C18 Column using an isocratic mobile phase of acetonitrile and ammonium acetate buffer (pH 8.0, 10 mM) (55:45, v/v). The UV detection was performed at 285 nm. The method provides rapid resolution of Isavuconazole in a 50 uL injection. Result: Lower limit of Quantification (LLOQ) is 0.25 μg/ml in a 50 uL injection volume for Isavuconazole with a recovery consistently > 100 %. The assay is validated over linear range of 0.25 to 10 μg/ml. The intra-assay precision is < 3.53 % and inter-assay is <6.38% relative standard deviation of Isavuconazole. The method demonstrated clean separation, clinically acceptable detection limit and a linear range upto 25 ug/mL. Conclusion: The assay demonstrated applicability in quantifying the drug level and monitoring the therapeutic dose for maintaining effective biological level to have better response in fungal infected patients. The method is cheaper as compared to LC-MS/MS and Tandem Mass spectrometry and the results are reportable on the same day of blood collection.

A simple High-Performance Thin layer chromatography (HPTLC) method has been developed for determination of atenolol in human blood and viscera. The mobile phase was ethyl acetate, acetone, ethyl alcohol, ammonia solution in the ratio of 45:45:7:3. The densitometry scanning at 254 nm was found to be maximum absorption for standard atenolol. The standard and extracted atenolol from samples were detected by HPTLC and confirmed with authenticated spectra at 254 nm. The quantity of the atenolol determined to be 1.6 µg for viscera and 1.5 µg for blood sample.

Chlorpyrifos is a hazardous organophosphate pesticide used worldwide thus its biodegradation is need of the time. In the present study 13 bacterial strains were isolated from collected soil samples of different agro climatic regions and out of them one bacterial strain was screened out as potent degrader of Chlorpyrifos on the basis of percentage degradation using high pressure liquid chromatography (HPLC).

Foreign body ingestion is a common occurrence among children and adults with certain risk factors including advanced age and psychiatric diseases. However, in clinical practice we encounter healthy adults who are diagnosed with unintentional foreign body ingestion and are not able to remember it. These cases may be complicated by gastrointestinal perforations in case of ingesting sharp objects. Only clinical suspicion would help clinicians for prompt diagnosis in such cases.

Streptococcus mutans is a leading cariogenic pathogen of dental caries worldwide. Clinically, eliminating S. mutans from dental biofilms using antibiotics is not practical, because these agents indiscriminately kill other members of the resident flora, leading to ecological disruption and other negative clinical consequences. To develop target-specific antimicrobials, we evaluated several fusion peptides and identified a new peptide HP30 that showed a high selectivity for targeted killing of S. mutans.

France, Greece, Italy, and Spain the major sheep and goat milk producers in Europe, got the initiative through an interim of 30 years (1985 – 2015), to organize - through IDF - 7 symposiums aiming at the upgrade of the Dairy Sector. One major interest was the milk quality. Stepwise, the efforts followed cow milk structural development in organizing the testing laboratory, the definition of quality in composition (fat, protein, lactose, total solids), in Hygienic (Total Bacteria Count, Somatic Cell Count, antibiotics residues and Aflatoxin M1 contamination), adulteration with water and detection of milk species. EU, by Decision 2002/657/EC, defined the rules for the Directive 96/23/EC, enumerated the testing methods, the demands in sampling procedures, the minimum limits of performance, the quality control (ISO 17025) and the interpretation of results. The equivalency of results from different laboratories, through ISO 17025, demanded the application of ISO analytical standards.
