To study on the level of serum di-n-butyl phthalate (DBP), di-2-ethylhexyl phthalate (DEHP) in normal children by using gas chromatography. Gas chromatography method was established. DBP, DEHP in normal children were detected, and their reference level was calculated, DBP and DEHP level in different age and genders were analysed. DBP could be detected in 110 serum samples from total 310 samples, and DEHP could be detected in 118 serum samples from the total 310 samples. The detected contrations of DBP range from non detectable to 0.98 ng/ml, P75 was 0.68 ng/ml, P95 was 0.75 ng/ml. There was no difference in the detection ratios between females and males, while baby group detection ratios was lower than other groups. The detected contrations of DEHP range from non detectable to 0.94 ng/ml, P75 was 0.67 ng/ml, P95 was 0.74 ng/ml. There was no difference in the detection ratios between females and males. While there was difference among age groups. The study domonstrated that DBP and DEHP concentrations in normal children are very low. The refrence level of DBP was suggested as lower than 0.75 ng/ml, DHEP was suggested as lower than 0.74 ng/ml.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
