Women are underrepresented in science and engineering, with the underrepresentation increasing in career stage. We analyze gender differences at critical junctures in the STEM pathway--graduate training and the early career--using UMETRICS administrative data matched to the 2010 Census and W-2s. We find strong gender separation in teams, although the effects of this are ambiguous. While no clear disadvantages exist in training environments, women earn 10% less than men once we include a wide range of controls, most notably field of study. This gap disappears once we control for women's marital status and presence of children.
Salivary gland hypofunction causes significant morbidity and loss of quality of life for head and neck cancer patients treated with radiotherapy. Preventing hypofunction is an unmet therapeutic need. We used an adeno-associated virus serotype 2 (AAV2) vector expressing the human neurotrophic factor neurturin (CERE-120) to treat murine submandibular glands either pre- or post-irradiation (IR). Treatment with CERE-120 pre-IR, not post-IR, prevented hypofunction. RNA sequencing (RNA-seq) analysis showed reduced gene expression associated with fibrosis and the innate and humoral immune responses. We then used a minipig model with CERE-120 treatment pre-IR and also compared outcomes of the contralateral non-IR gland. Analysis of gene expression, morphology, and immunostaining showed reduced IR-related immune responses and improved secretory mechanisms. CERE-120 prevented IR-induced hypofunction and restored immune homeostasis, and there was a coordinated contralateral gland response to either damage or treatment. CERE-120 gene therapy is a potential treatment for head and neck cancer patients to influence communication among neuronal, immune, and epithelial cells to prevent IR-induced salivary hypofunction and restore immune homeostasis.
This paper reports the occurrence of human parvovirus B19 infection in seven healthcare workers in an acute hospital. The clinical presentation mimicked that of rubella and the diagnosis was made by the detection of human parvovirus B19 IgM antibody in blood samples taken from the affected members of staff. The paper discusses the importance of accurate diagnosis of B19 infection because this virus has been implicated in causing or exacerbating a variety of medical conditions. B19 infection may be serious for people with chronic haemolytic anaemias, those who are immunocompromised or those who are pregnant. B19 infection in pregnancy may be a cause of hydrops fetalis, particularly if the infection occurs during the second trimester. This is in contrast to the risk of intra-uterine rubella infection which is maximal in the first few weeks of pregnancy and which affects fetal development. The paper highlights the need for guidelines for occupational health practitioners on the management of parvovirus B19 infection and the need to make healthcare workers aware of the importance of this infection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
