In this paper, it is analyzed the temporal variation of organochlorine pesticides (OCPs) in water and sediments from a river influenced by activity an agricultural field tropical country during period 2013-2016. The novelty consists increasing studies concentrations OCPs rivers for contributing to establish thresholds that allow protect biota soils waters. mean values dissolved sorbed on varied...

This paper analyzes the interplay between dissipativity and stability properties in continuous-time infinite-horizon Optimal Control Problems (OCPs). We establish several relations these properties, which culminate a set of equivalence conditions. Moreover, we investigate convergence optimal adjoint trajectories. The workhorse for our investigations is notion strict OCPs, has been coined contex...

Sewage and industrial effluents from biological treatment plant have been widely used for agricultural irrigation in north part of China. However, effluents after biological treatment still contain heavy metals and persistent organic contaminants. The persistent organic contaminants accumulated in soil may transfer through the food chains and cause adverse health effects on human or biological ...

Aging cells not only cease growing, but also secrete various proteins such as inflammatory cytokines. This secretory phenomenon is known the senescence‑associated phenotype (SASP). The aim of present study was to elucidate effects senescence on differentiation osteoclast precursors (OCPs) and corresponding SASP. RAW264.7 were used OCPs cultured passage (P)5, P10 P20. Cell proliferation assays, ...

BACKGROUND Endometriosis is considered an estrogen-dependent disease. Persistent environmental chemicals that exhibit hormonal properties, such as organochlorine pesticides (OCPs), may affect endometriosis risk. OBJECTIVE We investigated endometriosis risk in relation to environmental exposure to OCPs. METHODS We conducted the present analyses using data from the Women's Risk of Endometrios...

OBJECTIVE To estimate the effect of the number of cycles of oral contraceptive pills (OCPs) dispensed per visit on method continuation, pill wastage, use of services, and health care costs. METHODS We used paid claims data for 82,319 women dispensed OCPs through the California Family PACT (Planning, Access, Care, and Treatment) Program in January 2003 to examine contraceptive continuation and...

BACKGROUND Use of the oral contraceptive pill (OCP) has been reported to be associated with stroke. With current OCPs containing less than 50 micro g of ethinyl estradiol, and many earlier studies reporting the association between OCPs and stroke, subjected to biases, we determined whether such an association exists and, if so, the magnitude of the risk. METHODS Two independent searches were ...

BACKGROUND The enormous challenge to maternal well-being with associated maternal wastages during labour has remained an unsurmountable problem in Cameroon which reflects the current high maternal mortality rate. Evidence abounds that cost-effective and affordable health interventions like the use of the partograph will contribute to curb the alarming number of intrapartum maternal deaths. Howe...

Aquatic organisms are good bio-indicators of the environmental health in freshwater lakes; Xenobiotics are foreign materials to the organisms’ body and do not occur naturally in nature. Xenobiotics accumulate in adipose tissues due to high affinity to fatty tissues. This paper reports the levels of Organochlorine pesticide (OCPs) residues, their metabolites and Polychlorinated Biphenyl (PCBs) c...
