Weiguo Zhang

Nutr Rev 2021 Apr 9. Epub 2021 Apr 9.

W. Zhang is with the Las Colinas Institutes, Irving, Texas, USA.

The roles of the resting heart rate (RHR) have been actively investigated and increasingly recognized in recent decades, because of the growing evidence that fast RHR is associated with and predicts the risk of developing cardiovascular and metabolic disorders, as well as all-cause mortality. Long-chain omega-3 polyunsaturated fatty acids (PUFAs) (eg, eicosapentaenoic acid and docosahexaenoic acid) have been shown to have chronotropic effects on heartbeat in both healthy people and patients with various disease conditions. The aims of this review are (1) to briefly summarize the importance of elevated RHR in disease pathogenesis and mortality; (2) to provide an update on the negative chronotropic effect of omega-3 PUFAs on the heart; (3) to highlight how omega-3 PUFAs regulate heart rate through the autonomic nervous system - a central control mechanism; and (4) to highlight how omega-3 PUFAs modulate the trans-membrane ionic channels in cardiomyocytes - a fundamental mechanism of cardiac automaticity.

Involvement of cytotoxic Eomes-expressing CD4 T cells in secondary progressive multiple sclerosis.

Proc Natl Acad Sci U S A 2021 Mar;118(11)

Department of Immunology, National Institute of Neuroscience, National Center of Neurology and Psychiatry, Kodaira, Tokyo, 187-8502 Japan;

Multiple sclerosis (MS), a putative autoimmune disease of the central nervous system (CNS), commonly presents as relapsing-remitting MS (RRMS), characterized by recurrent episodes of peripheral disabling symptoms resulting from inflammatory CNS damage. Many RRMS patients transition to a chronic disease course with progressive neurological dysfunctions (secondary progressive MS, SPMS), with the progression rate varying between patients and over time. SPMS pathogenesis is now linked to immune-cell-mediated processes, although the mechanisms driving SPMS transition and progression remain elusive, and SPMS lacks biomarkers and effective treatments.

[Cobalamin in the complex treatment and prevention of cognitive impairment].

Zh Nevrol Psikhiatr Im S S Korsakova 2021 ;121(3):132-137

Sechenov First Moscow State Medical University (Sechenov University), Moscow, Russia.

Cognitive impairment (CI) develops not only in structural damage to the central nervous system, but also in encephalopathies of dysmetabolic and deficiency etiology. Recently, special attention is focused on the appearance of CI due to the deficiency of cobalamin (vitamin B) and folic acid (FA), the change in the level of homocysteine (HC). To detect vitamin B deficiency is possible by examining key biomarkers in serum based on a decrease in the levels of vitamin B and holotranscobalamin, and levels of methylmalonic acid (MMA) and HC.

Biomarkers and the Role of α-Synuclein in Parkinson's Disease.

Front Aging Neurosci 2021 23;13:645996. Epub 2021 Mar 23.

Department of Functional Neurosurgery, Beijing Neurosurgical Institute, Capital Medical University, Beijing, China.

Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by the presence of α-synuclein (α-Syn)-rich Lewy bodies (LBs) and the preferential loss of dopaminergic (DA) neurons in the substantia nigra (SN) pars compacta (SNpc). However, the widespread involvement of other central nervous systems (CNS) structures and peripheral tissues is now widely documented. The onset of the molecular and cellular neuropathology of PD likely occurs decades before the onset of the motor symptoms characteristic of PD, so early diagnosis of PD and adequate tracking of disease progression could significantly improve outcomes for patients.
