Preparation, Structure, Photoluminescent and Semiconductive Properties, and Theoretical Calculation of a Mononuclear Nickel Complex with 3-Hydroxy-2- Methylquinoline-4-Carboxylato Ligand.

Acta Chim Slov 2019 Jun;66(2):414-420

A novel nickel complex with mixed ligands [Ni(L)2(EtOH)2(MeOH)2] (HL = 3-hydroxy-2-methylquinoline-4-carboxylic acid) has been synthesized through solvothermal reaction and its crystal structure was determined by single-crystal X-ray diffraction technique. Single-crystal X-ray diffraction analyses reveals that the title compound crystallizes in the triclinic system of the P-1 space group, and exists as isolated mononuclear complex. The intermolecular hydrogen bonds lead to the formation of chains, and the layered supramolecular structure is formed by the strong ααααα stacking interactions. Read More

Mitochondria: The Retina's Achilles' Heel in AMD.

Adv Exp Med Biol 2021 ;1256:237-264

Department of Ophthalmology, University of Florida, Gainesville, FL, USA.

Strong experimental evidence from studies in human donor retinas and animal models supports the idea that the retinal pathology associated with age-related macular degeneration (AMD) involves mitochondrial dysfunction and consequent altered retinal metabolism. This chapter provides a brief overview of mitochondrial structure and function, summarizes evidence for mitochondrial defects in AMD, and highlights the potential ramifications of these defects on retinal health and function. Discussion of mitochondrial haplogroups and their association with AMD brings to light how mitochondrial genetics can influence disease outcome. Read More

Age-Related Macular Degeneration: From Epigenetics to Therapeutic Implications.

Adv Exp Med Biol 2021 ;1256:221-235

Department of Ophthalmology, Jacobs School of Medicine and Biomedical Sciences, State University of New York at Buffalo, Buffalo, NY, USA.

Aberrant regulation of epigenetic mechanisms, including the two most common types; DNA methylation and histone modification have been implicated in common chronic progressive conditions, including Alzheimer disease, cardiovascular disease, and age-related macular degeneration (AMD). All these conditions are complex, meaning that environmental factors, genetic factors, and their interactions play a role in disease pathophysiology. Although genome wide association studies (GWAS), and studies on twins demonstrate the genetic/hereditary component to these complex diseases, including AMD, this contribution is much less than 100%.

Innate Immunity in Age-Related Macular Degeneration.

Adv Exp Med Biol 2021 ;1256:121-141

Section on Neuron-Glia Interactions in Retinal Disease, National Eye Institute, National Institutes of Health, Bethesda, MD, USA.

Multiple lines of investigation have demonstrated that inflammation plays significant roles in etiology of age-related macular degeneration (AMD). Although interventional trials in AMD therapy targeting inflammatory pathways have been conducted, they have not yet been successful and a detailed understanding as to why some have failed is still elusive. One limitation is the relative dearth of information on how immune cells interact with retinal cells to generate AMD phenotypes at each disease stage. Read More

Bruch's Membrane and the Choroid in Age-Related Macular Degeneration.

Adv Exp Med Biol 2021 ;1256:89-119

Wilmer Ophthalmological Institute, Johns Hopkins Hospital, Baltimore, MD, USA.

A healthy choroidal vasculature is necessary to support the retinal pigment epithelium (RPE) and photoreceptors, because there is a mutualistic symbiotic relationship between the components of the photoreceptor/retinal pigment epithelium (RPE)/Bruch's membrane (BrMb)/choriocapillaris (CC) complex. This relationship is compromised in age-related macular degeneration (AMD) by the dysfunction or death of the choroidal vasculature. This chapter will provide a basic description of the human Bruch's membrane and choroidal anatomy and physiology and how they change in AMD. Read More

A positive charge region of Salmonella FliI is required for ATPase formation and efficient flagellar protein export.

Commun Biol 2021 Apr 12;4(1):464. Epub 2021 Apr 12.

Graduate School of Frontier Biosciences, Osaka University, Suita, Osaka, Japan.

The FliHFliI complex is thought to pilot flagellar subunit proteins from the cytoplasm to the transmembrane export gate complex for flagellar assembly in Salmonella enterica. FliI also forms a homo-hexamer to hydrolyze ATP, thereby activating the export gate complex to become an active protein transporter. However, it remains unknown how this activation occurs. Read More

Conditions Favoring Increased COVID-19 Morbidity and Mortality: Their Common Denominator and its Early Treatment.

Eliot Shevel

Mo Med 2021 Mar-Apr;118(2):113-115

Head of the South African Headache Society, the South African affiliate of the International Headache Society. He is founder and practices at The Headache Clinic in Johannesburg, South Africa.

The factors contributing to increased morbidity and mortality in SARS-CoV-2 infection are diverse, and include diabetes, obesity, Chronic Obstructive Pulmonary Disease (COPD), advanced age, and male sex. Although there is no obvious connection between these, they do have one common denominator-they all have a tendency towards lower urine pH, which may indicate a lower-than-normal tissue pH. Furthermore, it has been shown that lower pH has two important negative influences: 1) it enhances viral fusion via the endosomal route, thereby facilitating viral multiplication; and 2) it facilitates increased production of inflammatory cytokines, thereby exacerbating the cytokine storm.

Corresponding author: Chen Rui, Email:

Over the last decade, chronic critically ill (CCI) has emerged as an epidemic in intensive care unit (ICU) survivors worldwide. Advances in ICU technology and implementation of care bundles has significantly decreased early deaths of critically ill patients, and have allowed them to survive previously lethal multiple organ failure (MOF). However, more and more survivors leave persistent low grade organ dysfunctions, depend on continues organ support, need to stay in ICU, and become CCI patients. Read More
