Oxidized forms of uromodulin promote calcium oxalate crystallization and growth, but not aggregation.

Int J Biol Macromol 2022 Jun 22. Epub 2022 Jun 22.

Medical Proteomics Unit, Office for Research and Development, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand. Electronic address:

Roles of an abundant human urinary protein, uromodulin (UMOD), in kidney stone disease were previously controversial. Recently, we have demonstrated that oxidative modification reverses overall modulatory activity of whole urinary proteins, from inhibition to promotion of calcium oxalate (CaOx) stone-forming processes. We thus hypothesized that oxidation is one of the factors causing those previously controversial UMOD data on stone modulation. Read More

Phosphatidic acid binds to and stimulates the activity of ARGAH2 from Arabidopsis.

Plant Physiol Biochem 2022 Jun 16;185:344-355. Epub 2022 Jun 16.

Department of Botany, University of Delhi, Delhi, 110007, India. Electronic address:

Phosphatidic acid (PA) has emerged as an important lipid signal during abiotic and biotic stress conditions such as drought, salinity, freezing, nutrient starvation, wounding and microbial elicitation. PA acts during stress responses primarily via binding and translocating target proteins or through modulating their activity. Owing to the importance of PA during stress signaling and developmental stages, it is imperative to identify PA interacting proteins and decipher their specific roles. Read More

Economic gradients in loneliness, social isolation and social support: Evidence from the UK Biobank.

Soc Sci Med 2022 Jun 9;306:115122. Epub 2022 Jun 9.

Centre for Health Economics, Monash University, 900 Dandenong Road, Caulfield East, VIC, 3145, Australia.

Despite the substantial literature on how loneliness is associated with poor health and premature mortality, there is little detailed research on the extent of its economic gradients. We provide this evidence using a sample of around 400,000 respondents aged 40-70 years from the UK Biobank, who were assessed between 2006 and 2010. We focus on differences in loneliness, as well as social isolation and a lack of social support, across educational attainment, household income, local area deprivation, and recent experience of financial stress.

Protecting mental health during periods of financial stress: Evidence from the Australian Coronavirus Supplement income support payment.

Soc Sci Med 2022 Jun 18;306:115158. Epub 2022 Jun 18.

Melbourne Institute: Applied Economic & Social Research, The University of Melbourne, Australia; Institute of Labor Economics (IZA), Bonn, Germany.

This paper investigates whether the Australian government's Coronavirus Supplement, a temporary income support payment for unemployed jobseekers during the height of the COVID-19 pandemic, protected mental health (frequency of feeling anxious or depressed during the past week) by lowering financial stress (how comfortable people are in paying for essential services). We use unique nationally representative repeated cross-sectional data on 3843 unemployed Australian adults over the period April 6, 2020 to May 10, 2021. We find that the Coronavirus Supplement payment significantly reduced reported financial stress, and lower financial stress was associated with lower mental distress. Read More

Department of Biochemistry and Microbiology, Faculty of Science, Engineering and Agriculture, University of Venda, Private Bag X5050, Thohoyandou 0950, South Africa. Electronic address:

Mistletoe plants that are positioned on the canopy of their hosts are more susceptible to UV radiation exposure. These aerial plants are resistant to damage by UV radiation due the presence of epidermal constituents such as the cuticle, cork layer, trichomes and antioxidant secondary metabolites. In response to the photo-oxidative stress associated with UV exposure, plants generally deploy photo-protective responsive mechanisms that involve the biosynthesis of UV absorbing phenolic compounds such as chlorogenic acids (CGAs).
