Stunting, IQ, and final school attainment in the Cebu Longitudinal Health and Nutrition Survey birth cohort.

Econ Hum Biol 2021 Apr 7;42:100999. Epub 2021 Apr 7.

USC-Office of Population Studies Foundation, Inc., University of San Carlos, Cebu City, Philippines.

School attainment is an important aspect of human capital, and a key determinant of long-term health and well-being. Early life deprivation and poor nutritional status are well known predictors of school entry and progression. We examine the persistence of early life influences and subsequent socioeconomic disadvantage (SED) across the multiple school continuation decisions that lead to final school attainment. Read More

LRRc17 controls BMSC senescence via mitophagy and inhibits the therapeutic effect of BMSCs on ovariectomy-induced bone loss.

Redox Biol 2021 Apr 1;43:101963. Epub 2021 Apr 1.

Key Laboratory of Transplant Engineering and Immunology, NHFPC; Regenerative Medicine Research Center; National Clinical Research Center for Geriatrics, West China Hospital, Sichuan University, Chengdu, PR China. Electronic address:

Senescence of bone marrow-derived mesenchymal stem cells (BMSCs) has been widely reported to be closely correlated with aging-related diseases, including osteoporosis (OP). Moreover, the beneficial functions of BMSCs decline with age, limiting their therapeutic efficacy in OP. In the present study, using RNA sequencing (RNA-Seq), we found that leucine-rich repeat containing 17 (LRRc17) expression in BMSCs was highly positively correlated with age. Read More

Neonatal exposure to monosodium glutamate results in impaired auditory brainstem structure and function.

Hear Res 2021 Apr 8;405:108243. Epub 2021 Apr 8.

Department of Anatomy, Lake Erie College of Osteopathic Medicine, 1858 West Grandview Blvd, Erie, PA 16504, United States. Electronic address:

Excitotoxic injury during the neonatal period has been shown to result in neurodegenerative changes in several different brain regions. Exposure to monosodium glutamate (MSG) during the first two postnatal weeks results in glutamate neurotoxicity in the cochlea and has been shown to result in damage to cochlear hair cells and fewer neurons in the spiral ganglion. Further, we have shown that such exposure results in fewer neurons in the cochlear nucleus and superior olivary complex and abnormal expression of the calcium binding proteins calbindin and calretinin.

The transcriptional regulator GON4L is required for viability and hematopoiesis in mice.

Exp Hematol 2021 Apr 14. Epub 2021 Apr 14.

Departments of Internal MedicineCarver College of Medicine, University of Iowa, 375 Newton Road, Iowa City, IA, 52242, USA; Anatomy and Cell BiologyCarver College of Medicine, University of Iowa, 375 Newton Road, Iowa City, IA, 52242, USA; Interdisciplinary Graduate Program in Immunology, Carver College of Medicine, University of Iowa, 375 Newton Road, Iowa City, IA, 52242, USA. Electronic address:

The Gon4l gene encodes a putative transcriptional regulator implicated in the control of both cell differentiation and proliferation. Previously, we described a mutant mouse strain called Justy in which splicing of pre-mRNA generated from Gon4l is disrupted. This defect severely reduces, but does not abolish, GON4L protein expression, and blocks the formation of early B-lineage progenitors, suggesting Gon4l is required for B cell development in vertebrates.

SAGA and SAGA-like SLIK transcriptional coactivators are structurally and biochemically equivalent.

J Biol Chem 2021 Apr 14:100671. Epub 2021 Apr 14.

Department of Biochemistry and Molecular Biology, Biomedicine Discovery Institute, Monash University, Clayton, VIC 3800, Australia. Electronic address:

The SAGA-like complex SLIK is a modified version of the Spt-Ada-Gcn5-Acetyltransferase (SAGA) complex. SLIK is formed through C-terminal truncation of the Spt7 SAGA subunit, causing loss of Spt8, one of the subunits that interacts with the TATA-binding protein (TBP). SLIK and SAGA are both coactivators of RNA polymerase II transcription in yeast and both SAGA and SLIK perform chromatin modifications. Read More

Megaprosthesis Versus Allograft Prosthesis Composite for the Management of Massive Skeletal Defects: A Meta-Analysis of Comparative Studies.

Curr Rev Musculoskelet Med 2021 Apr 17. Epub 2021 Apr 17.

Department of Orthopedics, All India Institute of Medical Sciences (AIIMS), New Delhi, 110029, India.

Gaseous environment modulates volatile emission and viability loss during seed artificial ageing.

Planta 2021 Apr 17;253(5):106. Epub 2021 Apr 17.

Department of Comparative Plant and Fungal Biology, Royal Botanic Gardens, Kew, Wakehurst Place, Ardingly, UK.

Main Conclusion: Modulation of the gaseous environment using oxygen absorbers and/or silica gel shows potential for enhancing seed longevity through trapping toxic volatiles emitted by seeds during artificial ageing. Volatile profiling using non-invasive gas chromatography-mass spectrometry provides insight into the specific processes occurring during seed ageing. Production of alcohols, aldehydes and ketones, derived from processes such as alcoholic fermentation, lipid peroxidation and Maillard reactions, are known to be dependent on storage temperature and relative humidity, but little is known about the potential modulating role of the gaseous environment, which also affects seed lifespan, on volatile production.
