Laparoscopic and Robot-assisted Laparoscopic Reimplantation for Lower Ureter Pathology. A Multi-institutional Comparative Study in 1343 Patients.

Objective: To evaluate the outcomes of children with vesicoureteral reflux (VUR) and obstructive megaureter (OM) utilizing various laparoscopic and robot-assisted approaches.

Materials And Methods: Retrospective review of all pediatric laparoscopic and robot-assisted cases for lower ureter pathology was performed between 2016-2022 in 13 academic centers worldwide. Five surgical approaches were assessed: LEUR, LVCUR, LDECUR, RALUR, and RADECUR.

Detection of Dibutyl Phthalate in Surface Water by Fluorescence Polarization Immunoassay.

Dibutyl phthalate (DBP) is widely used as a plasticizer in the production of polymeric materials to give them flexibility, strength and extensibility. However, due to its negative impact on human health, in particular reproductive functions and fetal development, the content of DBP must be controlled in food and the environment. The present study aims to develop a sensitive, fast and simple fluorescence polarization immunoassay (FPIA) using monoclonal antibodies derived against DBP (MAb-DBP) for its detection in open waters.

Development and validation of a HPLC-MS/MS method for the analysis of fatty acids - in the form of FAME ammonium adducts - in human whole blood and erythrocytes to determine omega-3 index.

Recent scientific studies in the field of health and nutrition have unanimously affirmed the importance of consuming the omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), because of their cardioprotective properties. Fatty acid profiling in erythrocyte membranes allows the omega-3 index, which is a recognized indicator of the risk of developing cardiovascular disease, to be calculated. One consequence of the upward trend in healthy lifestyles and longevity is an increase in the number of studies into the omega-3 index, which requires a reliable method for the quantitative analysis of fatty acids.

Models of Ni- and Co-ion occupation in LiNiCoPOorthophosphate and its magnetic structure.

The neutron diffraction, magnetic and heat capacity measurements have been carried out to study the polycrystalline sample LiNiCoPOprepared by the glycerol-nitrate synthesis method. Models of Ni- and Co-ion occupation the 4octahedral position in a crystal structure LiNiCoPOare calculated for a paramagnetic state. The best model is the Ni- and Co-ions occupy the 4site inpatent space-group in sequence Ni-Co-Ni-Co or Co-Ni-Co-Ni.
