Characterization of Excited-State Electronic Structure in Diblock π-Conjugated Oligomers with Adjustable Linker Electronic Coupling.

Diblock conjugated oligomers are π-conjugated molecules that contain two segments having distinct frontier orbital energies and HOMO-LUMO gap offsets. These oligomers are of fundamental interest to understand how the distinct π-conjugated segments interact and modify their excited state properties. The current paper reports a study of two series of diblock oligomers that contain oligothiophene (T) and 4,7-bis(2-thienyl)-2,1,3-benzothiadiazole (TBT) segments that are coupled by either ethynyl (-C≡C-) or -(-C≡C-)Pt(II)(PBu) acetylide linkers.

Elevated Levels of Procoagulant Microvesicles and Tissue-Factor Bearing Microvesicles in Malaria Patients.

Background: Procoagulant microvesicles (MVs) are submicron membrane fragments released from activated cells and cells undergoing apoptosis. The procoagulant activity of MVs is enhanced in the presence of tissue factor (TF). MVs and TF are active mediators that induce pro-inflammatory response and prothrombotic tendency and have been linked to the severity of several disorders, including malaria infection.

White-tailed deer () may serve as a wildlife reservoir for nearly extinct SARS-CoV-2 variants of concern.

The spillover of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from humans to white-tailed deer (WTD) and its ability to transmit from deer to deer raised concerns about the role of WTD in the epidemiology and ecology of the virus. Here, we present a comprehensive cross-sectional study assessing the prevalence, genetic diversity, and evolution of SARS-CoV-2 in WTD in the State of New York (NY). A total of 5,462 retropharyngeal lymph node samples collected from free-ranging hunter-harvested WTD during the hunting seasons of 2020 (Season 1, September to December 2020, n = 2,700) and 2021 (Season 2, September to December 2021, n = 2,762) were tested by SARS-CoV-2 real-time RT-PCR (rRT-PCR).
