Changing patterns in the highly contributing aerosol types/species across the globe in the past two decades.
Gupta G, Ratnam MV, Madhavan BL. Gupta G, et al. Among authors: ratnam mv. Sci Total Environ. 2023 Nov 1;897:165389. doi: 10.1016/j.scitotenv.2023.165389. Epub 2023 Jul 7. Sci Total Environ. 2023. PMID: 37423288
Therefore, a rigorous attempt is made in this study to obtain the long-term changing patterns in the contribution of different aerosol types/species, to the total aerosol loading. ...The detailed analysis showed that there exists an overall higher contribution of aerosols …

Is the atmospheric boundary layer altitude or the strong thermal inversions that control the vertical extent of aerosols?
Prasad P, Basha G, Ratnam MV. Prasad P, et al. Among authors: ratnam mv. Sci Total Environ. 2022 Jan 1;802:149758. doi: 10.1016/j.scitotenv.2021.149758. Epub 2021 Aug 19. Sci Total Environ. 2022. PMID: 34454150
This raised a question that up to what extent ABL altitude acts as a capping layer for these pollutants? From the detailed analysis carried out using long-term (2010-2018) lidar observations and simultaneous radiosonde profiles obtained from Gadanki, India, we show that 't …

Changing patterns in aerosol vertical distribution over South and East Asia.
Ratnam MV, Prasad P, Raj STA, Raman MR, Basha G. Ratnam MV, et al. Sci Rep. 2021 Jan 11;11(1):308. doi: 10.1038/s41598-020-79361-4. Sci Rep. 2021. PMID: 33431935 Free PMC article.
However, aerosol vertical distribution in the changing climate is not fully understood. By combining long-term satellite observations from MODIS and CALIOP, here we show rapid changes in the aerosol vertical distribution over the South and East Asia covering India and Chin …

A mutual response between surface temperature and black carbon mass concentration during the daytime.
Talukdar S, Ratnam MV. Talukdar S, et al. Among authors: ratnam mv. Sci Total Environ. 2021 Mar 10;759:143477. doi: 10.1016/j.scitotenv.2020.143477. Epub 2020 Nov 11. Sci Total Environ. 2021. PMID: 33220999
The mutual response between surface temperature and the mass concentration of regional black carbon (BC) aerosols has still remained far from understanding due to its complex nature. A detailed analysis presented in this study using long-term data indicates a significant p …

Estrogen-induced and TAFII30-mediated gene repression by direct recruitment of the estrogen receptor and co-repressors to the core promoter and its reversal by tamoxifen.
Hao H, d'Alincourt-Salazar M, Kelley KM, Shatnawi A, Mukherjee S, Shah YM, Ratnam M. Hao H, et al. Among authors: ratnam m. Oncogene. 2007 Dec 13;26(57):7872-84. doi: 10.1038/sj.onc.1210592. Epub 2007 Jun 25. Oncogene. 2007. PMID: 17599049
ER associated with the chromosomal P4 promoter and SMRT and NCoR associated with it in an ER-dependent manner; these associations were favored by E2 but disrupted by Tam, in the short term, without changes in ER expression. TAFII30 was required for optimal P4 promoter acti …
