Thyroid Volume in Pregnancy is Associated with Parity, Gestational Age, and Body Mass Index in an Iodine-sufficient Area.

Objective:  We compared thyroid volume (TV) and presence of nodular goiter (NG) in pregnant vs. non-pregnant women in an iodine-sufficient area. We also evaluated the relationship between gestational age, parity, and TV in the pregnant women group, and determined the 2.

Herbicide and Cytogenotoxic Activity of Inclusion Complexes of Leaf Essential Oil and -Caryophyllene on 2-Hydroxypropyl--cyclodextrin.

The present investigation aimed to develop inclusion complexes (ICs) from (GAU) essential oil (EO) and its major compound -caryophyllene (-CAR), and to evaluate their herbicidal (against and ) and cytogenotoxic (on ) activities. The ICs were obtained using 2-hydroxypropyl--cyclodextrin (HPCD) and they were prepared to avoid or reduce the volatility and degradation of GAU EO and -CAR. The ICs obtained showed a complexation efficiency of 91.

Autonomous Environment Disinfection Based on Dynamic UV-C Irradiation Map.

The COVID-19 pandemic has become a worldwide concern and has motivated the entire scientific community to join efforts to fight it. Studies have shown that SARS-CoV-2 remains viable onsurfaces for days, increasing the chances of human infection. Environmental disinfection is thus an important action to prevent the transmission of the virus.

Usability and Accuracy of a Smartwatch for the Assessment of Physical Activity in the Elderly Population: Observational Study.

Background: Regular physical activity (PA) contributes to the primary and secondary prevention of several chronic diseases and reduces the risk of premature death. Physical inactivity is a modifiable risk factor for cardiovascular disease and a variety of chronic disorders such as diabetes, obesity, hypertension, bone and joint diseases (eg, osteoporosis and osteoarthritis), depression, and colon and breast cancer. Population aging and the related increase in chronic diseases have a major impact on the health care systems of most Western countries and will produce an even more significant effect in the future.

LC-MS/MS analysis of vitamin D metabolites in human serum using a salting-out based liquid-liquid extraction and DAPTAD derivatization.

LC-MS/MS has recently emerged as the best-practice for simultaneous analysis of vitamin D metabolites. We have developed and validated an LC-MS/MS method for simultaneous quantification of 25(OH)D, 24,25(OH)D, and 3-epi-25(OH)D in human serum. These three metabolites were extracted from 50 μL of serum by acetonitrile protein precipitation followed by salting-out of acetonitrile.
