Article Synopsis
  • Birthweight is influenced by maternal psychological stress during pregnancy, but the effects may differ based on the infant's sex.
  • A study analyzed 5,702 mother-newborn pairs, comparing those whose mothers reported high stress against those with lower stress levels, specifically examining the impact on male and female infants.
  • Results showed that male infants exposed to high stress had higher birthweights, while female infants had lower birthweights, suggesting different adaptive strategies to maternal stress based on the infant's sex.

P3HT:PCBM based photovoltaic devices with different active layer thicknesses (ALTs) were examined in photodetector and solar cell operation modes. The photodetector photocurrent spectra and solar cell current density-voltage characteristics were measured. All experimental results were reproduced by the unique drift-diffusion model which excludes the optical interference and allows the parameters of photogeneration, transport, and recombination to be ALT dependent.

The emergence and spread of 2019 novel coronavirus have led to an unprecedented public health crisis around the globe, threatening the lives of millions of people. We report a severe case of COVID-19 in a patient with chronic lymphocytic leukemia and describe primarily the clinical presentation and the challenges encountered in the COVID-19 diagnosis, treatment, and specimens sampling pitfalls. This case highlights the importance of a comprehensive diagnostic approach of pneumonia in immunocompromised hosts, including timely and safe bronchoscopy, because of the broad differential diagnosis, more challenging with the current outbreak of COVID-19.
