Coronary artery disease in East and South Asians: differences observed on cardiac CT.

Heart 2021 May 13. Epub 2021 May 13.

MonashHEART, Monash Health and Monash University, Clayton, Victoria, Australia

Epidemiological studies have observed East Asians (EAs) are significantly less likely to develop or die from coronary artery disease (CAD) compared with Caucasians. Conversely South Asians (SAs) develop CAD at higher rate and earlier age. Recently, a range of features derived from cardiac CT have been identified which may further characterise ethnic differences in CAD. Read More

J Gerontol B Psychol Sci Soc Sci 2021 May 7. Epub 2021 May 7.

College of Nursing, The Pennsylvania State University, University Park, PA.

Objectives: The current study examined within-person associations of self-reports of impaired current memory functioning and perceived decline with depressive symptoms in older adults without cognitive impairment, and whether these associations were moderated by individuals' levels of neuroticism, conscientiousness, and extraversion.

Methods: Samples were drawn from the Einstein Aging Study (EAS), Rush Memory and Aging Project (MAP), Minority Aging Research Study (MARS), Health and Retirement Study (HRS), and National Health and Aging Trends Study (NHATS), with over 8,000 participants (65+ years) included across datasets. In a series of coordinated analyses, multilevel linear models tested within-person relationships over periods of up to 22 years. Read More

Trypanosoma cruzi extracellular amastigotes engage Rac1 and Cdc42 to invade RAW macrophages.

Microbes Infect 2021 May 3:104837. Epub 2021 May 3.

Departamento de Microbiologia, Imunologia e Parasitologia, Universidade Federal de São Paulo, São Paulo, Brazil; current address: Division of Cell Biology and Molecular Medicine, Institute for Molecular Bioscience, The University of Queensland, St. Lucia, Brisbane, QLD 4072, Australia. Electronic address:

Cell invasion by Trypanosoma cruzi extracellular amastigotes (EAs) relies significantly upon the host cell actin cytoskeleton. In past decades EAs have been established as a reliable model for phagocytosis inducer in non-phagocytic cells. Our current hypothesis is that EAs engage a phagocytosis-like mechanism in non-professional phagocytic cells; however, the molecular mechanisms in professional phagocytes still remain unexplored.

Type 2 diabetes is causally associated with reduced serum osteocalcin: A genome-wide association and Mendelian randomization study.

J Bone Miner Res 2021 May 6. Epub 2021 May 6.

Department of Endocrinology and Metabolism, Zhongshan Hospital, Fudan University, Shanghai, China.

Recent advances indicate that bone and energy metabolism are closely related. However, little direct evidence on causality has been provided in humans. We aimed to assess the association of three bone-related biomarkers 25 hydroxyvitamin D (25OHD), parathyroid hormone (PTH) and osteocalcin (OCN) with several metabolic phenotypes, and investigate any causal relevance to the associations using a Mendelian randomization (MR) study.

Laboratorio de Procesado de Imagen, E.T.S.I. Telecomunicación, Universidad de Valladolid, Paseo Belén 15, 47011 Valladolid, Spain.

Numerous methods in the extensive literature on magnetic resonance imaging (MRI) reconstruction exploit temporal redundancy to accelerate cardiac cine. Some of them include motion compensation, which involves high computational costs and long runtimes. In this work, we proposed a method-elastic alignedSENSE (EAS)-for the direct reconstruction of a motion-free image plus a set of nonrigid deformations to reconstruct a 2D cardiac sequence. Read More

Detection of the First Epoxyalcohol Synthase/Allene Oxide Synthase (CYP74 Clan) in the Lancelet (, Chordata).

Int J Mol Sci 2021 Apr 29;22(9). Epub 2021 Apr 29.

Kazan Institute of Biochemistry and Biophysics, FRC Kazan Scientific Center of RAS, P.O. Box 30, 420111 Kazan, Russia.

The CYP74 clan cytochromes (P450) are key enzymes of oxidative metabolism of polyunsaturated fatty acids in plants, some Proteobacteria, brown and green algae, and Metazoa. The CYP74 enzymes, including the allene oxide synthases (AOSs), hydroperoxide lyases, divinyl ether synthases, and epoxyalcohol synthases (EASs) transform the fatty acid hydroperoxides to bioactive oxylipins. A novel CYP74 clan enzyme CYP440A18 of the Asian (Belcher's) lancelet (, Chordata) was biochemically characterized in the present work. Read More

Inhibitors of Protein Convertase Subtilisin/Kexin 9 (PCSK9) and Acute Coronary Syndrome (ACS): The State-of-the-Art.

J Clin Med 2021 Apr 5;10(7). Epub 2021 Apr 5.

Department of Translational Medical Sciences, "Federico II" University of Naples, Via S. Pansini 5, 80131 Naples, Italy.

Acute Coronary Syndrome (ACS) remains one of the most frequent causes of morbidity and mortality in the world. Although the age- and gender-adjusted incidence of ACS is decreasing, the mortality associated with this condition remains high, especially 1-year after the acute event. Several studies demonstrated that PCSK9 inhibitors therapy determine a significant reduction of major adverse cardiovascular events (MACE) in post-ACS patients, through a process of plaque modification, by intervening in lipid metabolism and platelet aggregation and finally determining an improvement in endothelial function.

PLoS One 2021 22;16(4):e0250206. Epub 2021 Apr 22.

Department of Forensic Medicine, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei Province, China.

The present study used the previously constructed 32-plex InDels panel to investigated the genetic diversity of four ethnic minorities (Hui, Mongol, Uygur and Kazakh) from Xinjiang, and analyzed the genetic relationships between the four populations and 27 reference populations. No significant deviations were observed from the Hardy-Weinberg equilibrium (HWE) at the 32 InDels for each population. The average observed heterozygosity (Hexp), average polymorphic information content (PIC), combined power of discrimination (CPD) and cumulative probability of exclusion (CPE) for the 32 InDels were all higher than the Qiagen Investigator DIPplex kit in the four populations from Xinjiang.

Effectiveness of Place-based Mapping in Electric-Acoustic Stimulation Devices.

Otol Neurotol 2021 Jan;42(1):197-202

Department of Otolaryngology/Head and Neck Surgery, School of Medicine.

Background: The default mapping procedure for electric-acoustic stimulation (EAS) devices uses the cochlear implant recipient's unaided detection thresholds in the implanted ear to derive the acoustic settings and assign the lowest frequency filter of electric stimulation. Individual differences for speech recognition with EAS may be due to discrepancies between the electric frequency filters of individual electrode contacts and the cochlear place of stimulation, known as a frequency-to-place mismatch. Frequency-to-place mismatch of greater than 1/2 octave has been demonstrated in up to 60% of EAS users. Read More

The Effect of Ultra-slow Velocities on Insertion Forces: A Study Using a Highly Flexible Straight Electrode Array.

Otol Neurotol 2021 Apr 20. Epub 2021 Apr 20.

Department of Otolaryngology and Cluster of Excellence Hearing4all, Hannover Medical School, Hannover Collaborative Research Center 884, University of Mannheim, Mannheim, Germany.

Objective: The present study sought to 1) characterize insertion forces resulting from a flexible straight electrode array (EA) inserted at slow and ultra-slow insertion velocities, and 2) evaluate if ultra-slow velocities decrease insertion forces independent of other variables.

Background: Low insertion forces are desirable in cochlear implant (CI) surgery to reduce trauma and preserve hearing. Recently, ultra-slow insertion velocities (lower than manually feasible) have been shown to produce significantly lower insertion forces using other EAs. Read More

Bin Liu Jucai Yang

ACS Omega 2021 Apr 31;6(14):9813-9827. Epub 2021 Mar 31.

School of Chemical Engineering, Inner Mongolia Key Laboratory of Theoretical and Computational Chemistry Simulation, Inner Mongolia University of Technology, Hohhot 010051, People's Republic of China.

A systematic investigation of the silver-doped germanium clusters AgGe with = 1-13 in the neutral, anionic, and cationic states is performed using the unbiased global search technique combined with a double-density functional scheme. The lowest-energy minima of the clusters are identified based on calculated energies and measured photoelectron spectra (PES). Total atomization energies and thermochemical properties such as electron affinity (EA), ionization potential (IP), binding energy, hardness, and highest occupied molecular orbital-lowest unoccupied molecular orbital (HOMO-LUMO) gap are obtained and compared with those of pure germanium clusters.
