Differences in sensitivity to neoadjuvant chemotherapy among invasive lobular and ductal carcinoma of the breast and implications on surgery–A systematic review and meta-analysis
Autor: Dómhnall J. O'Connor, Matthew G. Davey, Laura R. Barkley, Michael J. Kerin
Publikováno v: Breast, Vol 61, Iss , Pp 1-10 (2022)
Meta-analysis of >87,000 patients demonstrates that patients with invasive lobular carcinoma of the breast are far less likely to achieve pCR of the breast or axilla compared to their ductal counterparts, receive less BCS and more frequently return p

Publikováno v: Atmospheric Chemistry and Physics, Vol 21, Pp 6605-6626 (2021)
Methane emissions associated with the production, transport, and use of oil and natural gas increase the climatic impacts of energy use; however, little is known about how emissions vary temporally and with commodity prices. We present airborne and g

Publikováno v: Atmospheric Chemistry and Physics, Vol 20, Pp 4545-4559 (2020)
As natural gas extraction and use continues to increase, the need to quantify emissions of methane (CH4), a powerful greenhouse gas, has grown. Large discrepancies in Indianapolis CH4 emissions have been observed when comparing inventory, aircraft ma

Publikováno v: Atmospheric Chemistry and Physics, Vol 17, Pp 13941-13966 (2017)
Natural gas infrastructure releases methane (CH4), a potent greenhouse gas, into the atmosphere. The estimated emission rate associated with the production and transportation of natural gas is uncertain, hindering our understanding of its greenhou
