Estimating the environmental burden of disease resulting from exposure to chemicals in European countries - potentials and challenges revealed in selected case studies.

Background: The increased use of chemicals leads to a continuous deposition of chemicals in the environment and to a continuous increase in exposure of the global and the European population. Comprehensive burden of disease analyses are however still missing for many countries.

Methods: Using the World Health Organization's Environmental Burden of Disease (EBD) approach and combining data from the European Human Biomonitoring (HBM) dashboard with disease and population data, we estimated the comprehensive attributable burden (AB) for the year 2021, in the best-case quantified by disability-adjusted life years (DALY).

A recurrent loss-of-function variant in DRC1 causes non-syndromic severe asthenozoospermia with favorable intracytoplasmic sperm injection and pregnancy outcomes.

Background: Asthenozoospermia, characterized by reduced sperm motility, is a common cause of male infertility. Multiple morphological abnormalities of the sperm flagella (MMAF) represent a severe and genetically heterogeneous form of asthenozoospermia. Over 50 genes have been associated, but approximately half of MMAF cases remain unexplained.

Receipt of Family Planning Services in the United States: 2022-2023.

Introduction: This report uses data from the 2022‒2023 National Survey of Family Growth (NSFG) to estimate receipt of family planning services by selected characteristics among females ages 15‒49 in the United States.

Methods: NSFG data were collected through a multi-mode design (in-person and web interviews) with a nationally representative samples of males and females ages 15-49 in the household population of the United States. This report uses data from 5,586 females who completed the survey between January 2022 and December 2023.

A signaling inspired synthetic toolkit for efficient production of tyrosine phosphorylated proteins.

Tyrosine phosphorylation is an important post-translational modification that regulates many biochemical signaling networks in multicellular organisms. To date, 46,000 tyrosines have been observed in human proteins, but relatively little is known about the function and regulation of most of these sites. A major challenge has been producing recombinant phospho-proteins in order to test the effects of phosphorylation.
