Nectin-4 promotes lymphangiogenesis and lymphatic metastasis in breast cancer by regulating CXCR4- LYVE1 axis.

Vascul Pharmacol 2021 May 1:106865. Epub 2021 May 1.

Cancer Biology Division, KIIT School of Biotechnology, Kalinga Institute of Industrial Technology, Campus-11, Patia, Bhubaneswar, Odisha 751024, India. Electronic address:

Tumor-induced lymphangiogenesis promotes tumor progression by generating new lymphatic vessels that helps in tumor dissemination to regional lymph nodes and distant sites. Recently, the role of Nectin-4 in cancer metastasis and angiogenesis has been studied, but its role in lymphangiogenesis is unknown. Here, we systematically delineated the role of Nectin-4 in lymphangiogenesis and its regulation in invasive duct carcinoma (IDC). Read More

Maternal smoking during pregnancy and offspring psychiatric disorder: a longitudinal birth cohort study.

Soc Psychiatry Psychiatr Epidemiol 2021 May 4. Epub 2021 May 4.

Psychology Department, Royal College of Surgeons in Ireland, Room 2, -1 Beaux Lane House, Lower Mercer Street Dublin 2, Dublin, Ireland.

Background: There is evidence that prenatal stress and smoking during pregnancy both independently increase the risk of offspring psychopathology. Here we examine whether increased levels of self-reported stress is associated with increased smoking in a population of pregnant women, and whether prenatal smoking is associated with offspring psychiatric diagnoses independent of prenatal stress exposure.

Method: Using a longitudinal birth cohort, we used ordered logistic regressions to examine associations between maternal stress and smoking during pregnancy. Read More

Synergistic aircraft and ground observations of transported wildfire smoke and its impact on air quality in New York City during the summer 2018 LISTOS campaign.

Sci Total Environ 2021 Jun 3;773:145030. Epub 2021 Feb 3.

City College of New York, New York, NY 10031, USA; NOAA - Cooperative Science Center for Earth System Sciences and Remote Sensing Technologies, New York, NY 10031, USA.

Air pollution associated with wildfire smoke transport during the summer can significantly affect ozone (O) and particulate matter (PM) concentrations, even in heavily populated areas like New York City (NYC). Here, we use observations from aircraft, ground-based lidar, in-situ analyzers and satellite to study and assess wildfire smoke transport, vertical distribution, optical properties, and potential impact on air quality in the NYC urban and coastal areas during the summer 2018 Long Island Sound Tropospheric Ozone Study (LISTOS).

Sudden infant death syndrome: deletions of glutathione-S-transferase genes M1 and T1 and tobacco smoke exposure.

Int J Legal Med 2021 May 1. Epub 2021 May 1.

Institute of Legal Medicine, University Hospital of Münster, Röntgenstr. 23, 48149, Münster, Germany.

In developed countries, sudden infant death syndrome (SIDS) is the leading cause of death in infants in their first year of life. The risk of SIDS is increased if parents smoked during pregnancy and in presence of the child. Glutathione S-transferases (GSTs) catalyse the conjugation of glutathione with electrophilic compounds and toxins, making them less reactive and easier to excrete. Read More

Impacts of local public smoking bans on smoking behaviors and tobacco smoke exposure.

Health Econ 2021 Apr 29. Epub 2021 Apr 29.

Department of Economics, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina, USA.

This paper examines the immediate and long-term effects of public smoking bans on smoking prevalence, smoking regularity, smoking intensity, and secondhand tobacco smoke exposure. We supplement the extensive literature on the effects of various types of tobacco control legislation on smoking behavior in developed countries by studying the provincial smoking bans and more recent national ban of a middle-income country, Argentina. We focus on the difference between full and partial smoking bans, and take advantage of the time and province variation in ban implementation in order to determine the causal effects of each type of ban.
