Social Stressors, Arboviral Infection, and Immune Dysregulation in the Coastal Lowland Region of Ecuador: A Mixed Methods Approach in Ecological Perspective.

Am J Trop Med Hyg 2021 Aug 2. Epub 2021 Aug 2.

Department of Obstetrics and Gynecology, University of Rochester School of Medicine and Dentistry, Rochester, New York.

Aedes aegypti, the mosquito that transmits arboviral diseases such as dengue (DENV), chikungunya (CHIKV), and Zika viruses (ZIKV), is present in tropical and subtropical regions of the world. Individuals at risk of mosquito-borne disease (MBD) in the urban tropics face daily challenges linked to their socio-environment conditions, such as poor infrastructure, poverty, crowding, and limited access to adequate healthcare. These daily demands induce chronic stress events and dysregulated immune responses. Read More

Role of FAM134 paralogues in endoplasmic reticulum remodeling, ER-phagy, and Collagen quality control.

EMBO Rep 2021 Aug 2:e52289. Epub 2021 Aug 2.

Institute of Biochemistry II (IBC2), Faculty of Medicine, Goethe University, Frankfurt am Main, Germany.

Degradation of the endoplasmic reticulum (ER) via selective autophagy (ER-phagy) is vital for cellular homeostasis. We identify FAM134A/RETREG2 and FAM134C/RETREG3 as ER-phagy receptors, which predominantly exist in an inactive state under basal conditions. Upon autophagy induction and ER stress signal, they can induce significant ER fragmentation and subsequent lysosomal degradation. Read More

Exploring the Origin and Relatedness of Maternal Lineages Through Analysis of Mitochondrial DNA in the Holstein Horse.

Front Genet 2021 15;12:632500. Epub 2021 Jul 15.

Institute of Animal Breeding and Husbandry, Christian-Albrechts-University, Kiel, Germany.

Maternal lineages are important for the breeding decision in the Holstein horse breed. To investigate the genetic diversity of the maternal lineages and the relationships between founder mares, the maternal inherited mitochondrial genome (except the repetitive part of the non-coding region) of 271 mares representing 75 lineages was sequenced. The sequencing predominantly revealed complete homology in the nucleotide sequences between mares from one lineage with exceptions in 13 lineages, where differences in one to three positions are probably caused by mutations or alternate fixation of heteroplasmy.

Structural insights into the allosteric site of Arabidopsis NADP-malic enzyme 2: role of the second sphere residues in the regulatory signal transmission.

Plant Mol Biol 2021 Jul 31. Epub 2021 Jul 31.

Centro de Estudios Fotosintéticos y Bioquímicos, Facultad de Ciencias Bioquímicas y Farmacéuticas, Universidad Nacional de Rosario (CEFOBI-CONICET-UNR), Suipacha 570, Rosario, Argentina.

Key Message: NADP-ME2 from Arabidopsis thaliana exhibits a distinctive and complex regulation by fumarate, acting as an activator or an inhibitor according to substrate and effector concentrations. In this work, we used molecular modeling approach and site-directed mutagenesis to characterized the NADP-ME2 structural determinants necessary for allosteric regulation providing new insights for enzyme optimization. Structure-function studies contribute to deciphering how small modifications in the primary structure could introduce desirable characteristics into enzymes without affecting its overall functioning.

Reperfusion mediates heme impairment with increased protein cysteine sulfonation of mitochondrial complex III in the post-ischemic heart.

J Mol Cell Cardiol 2021 Jul 28. Epub 2021 Jul 28.

Department of Integrative Medical Sciences, College of Medicine, Northeast Ohio Medical University, Rootstown, OH 44272, United States of America. Electronic address:

Diretoria de Atenção Primária e Rede Assistencial, Hospital Israelita Albert Einstein, São Paulo, São Paulo, Brasil.

A second wave of COVID-19 has demonstrated how challenging it will be to achieve sustained control of the disease, even with vaccination underway in many countries. Therefore, it remains relevant to keep improving our understanding of the distribution of COVID-19, especially of asymptomatic individuals, among different populations, and particularly in vulnerable regions. Hence, this population-based serosurvey had the objective of estimating the prevalence of individuals 18 years of age or older infected by SARS-CoV-2, and the proportion of asymptomatic individuals, among a vulnerable population living in an urban setting.

Localised expression of OsIAA29 suggests a key role for auxin in regulating development of the dorsal aleurone of early rice grains.

Planta 2021 Jul 29;254(2):40. Epub 2021 Jul 29.

School of Science and Technology, University of New England, Armidale, NSW, 2351, Australia.

Main Conclusion: Non-canonical AUX/IAA protein, OsIAA29, and ZmMPR-1 homologues, OsMRPLs, are part of an auxin-related signalling cascade operating in the dorsal aleurone during early rice grain development. Endosperm of rice and other cereals accumulates high concentrations of the predominant in planta auxin, indole-3-acetic acid (IAA) during early grain development. However, IAA signalling and function during endosperm development are poorly understood. Read More

Rajagiri College of Social Sciences (Autonomous), Rajagiri P.O, Kalamassery, Cochin, Kerala, 683 104, India.

Background: The lockdown associated with the COVID-19 pandemic is likely to impact people's mental health, especially those from economically disadvantaged and vulnerable sections of society. Mental health can be affected by many factors, including fear of disease transmission, from response measures against the pandemic like social distancing, movement restriction, fear of being in quarantine, loneliness, depression due to isolation, fear of losing work and livelihood and avoiding health care due to fear of being infected. Telephonic befriending intervention by non-specialists will be used to provide social and emotional support to the youth from the Deen Dayal Upadhyaya Grameen Kaushalya Yojana (DDUGKY), an initiative of the Government of India.
