Countries in South Asia are suffering severe PM pollution with rapid economic development, impacting human health and the environment. Whilst much attention has been given to understanding the contribution of primary emissions, the contribution of agriculture to PM concentrations, especially from agricultural ammonia (NH) emissions, remains less explored. Using an advanced regional atmospheric chemistry and transport modelling system (WRF-EMEP) with a new estimate of anthropogenic NH emissions inputs, we estimate the influence of agricultural NH emissions on surface PM in South Asia and evaluate the health impacts and the economic losses attributable to PM in 2018.

Article Synopsis
  • Over the past two decades, there has been a growing focus on diagnosing and managing inner ear schwannomas, especially regarding hearing rehabilitation through cochlear implants, but the terminology used to classify these tumors has been inconsistent and complex.
  • At the Ninth Quadrennial Conference in May 2023 in Bergen, Norway, experts reached a consensus to standardize terminology, ultimately agreeing on the term "inner ear schwannoma (IES)" to clearly describe tumors affecting the eighth nerve in the cochlea, vestibule, or semicircular canals.
  • The newly established classifications break down these tumors into three complexity levels: low (intravestibular, intracochlear), intermediate (with internal

Article Synopsis
  • Systemic lupus erythematosus (SLE) is an autoimmune disease more common in females, potentially linked to sex hormones, and the effects of a specific estrogen treatment (TSEC) on lupus-related organ damage remain unclear.
  • In a study involving ovariectomized mice, researchers tested how TSEC and other estrogen treatments affected B-cell development and kidney/salivary gland disease manifestations.
  • Results showed that TSEC did not worsen lupus symptoms in the mouse model and provided protection against bone loss, suggesting it could be a viable treatment option for osteoporosis and related symptoms in postmenopausal women with lupus.

  • Researchers analyzed high-throughput sequencing data from cotton leafroll dwarf virus in Mississippi, finding contigs similar to reverse transcriptases from plant pararetroviruses.
  • They conducted a detailed study that led to the identification of endogenous viral elements (EVEs) in upland cotton, named "endogenous cotton pararetroviral elements" (eCPRVE).
  • The study revealed a significant 15 kbp-long locus on chromosome A04, containing viral genes and suggesting a link to a new genus within the pararetrovirus family, along with evidence of recent evolutionary changes in related species.

Aging is associated with low bone and lean mass as well as alterations in the gut microbiota (GM). In this study, we determined whether the reduced bone mass and relative lean mass observed in old mice could be transferred to healthy young mice by GM transplantation (GMT). GM from old (21-month-old) and young adult (5-month-old) donors was used to colonize germ-free (GF) mice in three separate studies involving still growing 5- or 11-week-old recipients and 17-week-old recipients with minimal bone growth.

Background: Influenza A virus (IAV) infection leads to significant morbidity and mortality. Biological sex influences the immune responses to IAV infection, resulting in higher mortality in women of reproductive age. Previous studies revealed increased activation of T and B cells in female mice after IAV infection, but extensive analysis of sex differences in both innate and adaptive immune cells over time is lacking.

Inflammation has a significant effect on bone remodeling and can result in bone loss via increased stimulation of osteoclasts. Activated immunoglobulins, especially autoantibodies, can increase osteoclastogenesis and are associated with pathological bone loss. Whether immunoglobulins and mature B lymphocytes are important for general bone architecture has not been completely determined.

Estrogen has pronounced effects on the immune system, which also influences bone homeostasis. In recent years, stromal cells in lymphoid organs have gained increasing attention as they not only support the regulation of immune responses but also affect bone remodeling. A conditional knockout mouse model where estrogen receptor alpha (ERα) is deleted in CCL19-expressing stromal cells (Ccl19-Cre mice) was generated and bone densitometry was performed to analyze the importance of stromal cell-specific ERα signaling on the skeleton.
