Myristic acid defends against testicular oxidative stress, inflammation, apoptosis: Restoration of spermatogenesis, steroidogenesis in diabetic rats.

Life Sci 2021 May 11:119605. Epub 2021 May 11.

Department of Physiology, Faculty of Medicine, University of Malaya, 50603 Kuala Lumpur, Malaysia. Electronic address:

Diabetes mellitus (DM) may lead to testicular infertility while Myristic acid (MA) is beneficial to lower hyperglycaemia. Thus, we hypothesized that MA could protect testes against hyperglycaemia-induced damage in DM. DM was induced in adult male rats by high-fat diet consumption for 12 weeks, accompanied by a single dose streptozotocin injection. Read More

MCDCD: Multi-Source Unsupervised Domain Adaptation for Abnormal Human Gait Detection.

IEEE J Biomed Health Inform 2021 May 14;PP. Epub 2021 May 14.

For gait analysis, especially for the detection of subtle gait abnormalities, the collected datasets involve high variability across subjects due to inherent biometric traits and movement behaviors, leading to limited detection accuracy and poor generalizability. To address this, we propose a novel deep multi-source Unsupervised Domain Adaptation (UDA) approach, namely Maximum Cross-Domain Classifier Discrepancy (MCDCD), which aims to improve the classification performance on the test subject (target domain) by leveraging the information from multiple labelled training subjects (source domains). Specifically, the proposed model consists of a feature extractor and a domain-specific category classifier per source domain. Read More

J Anim Sci Technol 2021 Jan 31;63(1):77-90. Epub 2021 Jan 31.

Department of Animal Industry Convergence, Kangwon National University, Chuncheon 24341, Korea.

This study aimed to assess the impact of abnormal climate events on the production of Italian ryegrass (IRG), such as autumn low-temperature, severe winter cold and spring droughts in the central inland, southern inland and southern coastal regions. Seasonal climatic variables, including temperature, precipitation, wind speed, relative humidity, and sunshine duration, were used to set the abnormal climate events using principal component analysis, and the abnormal climate events were distinguished from normal using Euclidean-distance cluster analysis. Furthermore, to estimate the impact caused by abnormal climate events, the dry matter yield (DMY) of IRG between abnormal and normal climate events was compared using a -test with 5% significance level.

Cerebral Visual Impairment Characterized by Abnormal Visual Orienting Behavior With Preserved Visual Cortical Activation.

Invest Ophthalmol Vis Sci 2021 May;62(6):15

University of Washington, Department of Ophthalmology, Seattle, Washington, United States.

Purpose: Children with cerebral visual impairment (CVI) often have abnormal visual orienting behaviors due to impaired or damaged visual cortex. Alternatively, visual-cortical function is intact but visual information is not transformed downstream into an appropriate oculomotor output (visuomotor dysfunction). We examined visual, anatomic, and oculomotor assessments to distinguish visuomotor dysfunction from CVI associated with severely reduced visual-cortical response. Read More

Purinergic Signal 2021 May 12. Epub 2021 May 12.

Departamento de Neurobiología Celular y Molecular, Instituto de Neurobiología, Universidad Nacional Autónoma de México, Querétaro, Querétaro, México.

Cancer comprises a collection of diseases that occur in almost any tissue and it is characterized by an abnormal and uncontrolled cell growth that results in tumor formation and propagation to other tissues, causing tissue and organ malfunction and death. Despite the undeniable improvement in cancer diagnostics and therapy, there is an urgent need for new therapeutic and preventive strategies with improved efficacy and fewer side effects. In this context, purinergic signaling emerges as an interesting candidate as a cancer biomarker or therapeutic target. Read More

RBL2 bi-allelic truncating variants cause severe motor and cognitive impairment without evidence for abnormalities in DNA methylation or telomeric function.

J Hum Genet 2021 May 13. Epub 2021 May 13.

The Genetics Institute, Rambam Health Care Campus, Haifa, Israel.

RBL2/p130, a member of the retinoblastoma family of proteins, is a key regulator of cell division and propagates irreversible senescence. RBL2/p130 is also involved in neuronal differentiation and survival, and eliminating Rbl2 in certain mouse strains leads to embryonic lethality accompanied by an abnormal central nervous system (CNS) phenotype. Conflicting reports exist regarding a role of RBL2/p130 in transcriptional regulation of DNA methyltransferases (DNMTs), as well as the control of telomere length. Read More
