OBJECTIVE: Hyperdense artery sign (HAS) on noncontrast brain computed tomography (CT) indicates an acute thrombus within the cerebral artery. It is a valuable imaging biomarker for diagnosing large-vessel occlusion; however, its identification may be challenging with the presence of vascular calcification. Dual-energy CT virtual noncalcium (VNCa) imaging using a 3-material decomposition algorithm is helpful for differentiating between calcification and hemorrhage. This study aimed to clarify the potential of VNCa imaging for differentiating HAS from vascular calcification...

CLINICAL ISSUE: Due to advances in diagnostics and therapy, the survival rate of patients with congenital heart defects is continuously increasing. The aim of this review is to compare various imaging modalities that are used in the diagnosis of congenital heart defects. METHODS: Transthoracic echocardiography is the imaging method of choice in the presence of a congenital heart defect because of its wide availability and non-invasiveness. It can be complemented by transesophageal echocardiography, cardiac catheterization, computed tomography (CT), and magnetic resonance imaging (MRI) of the heart and vessels close to the heart...

We report 18 coding-complete genome sequences of emerging SARS-CoV-2 Omicron sub-lineages JN.1, JN.1.4, and JN.1.11 from Bangladesh. Nasopharyngeal swab samples were obtained from individuals with COVID-19 symptoms between December 2023 and January 2024. Whole genome sequencing was performed following the ARTIC Network-based protocol using Oxford Nanopore Technology.

BACKGROUND: Methamphetamine is an illegal drug that poses serious public health concerns worldwide. Previous studies have demonstrated a strong association between methamphetamine abuse and non-lethal haemorrhagic stroke. Ischaemic stroke after methamphetamine intake is less common than haemorrhagic stroke. The present study investigated the clinical features and potential pathogenesis in a young methylamphetamine addict that presented with acute ischaemic stroke and reversible middle cerebral artery (MCA) occlusion...

PURPOSE: In a preclinical study using a swine myocardial infarction (MI) model, a delayed enhancement (DE)-multi-detector computed tomography (MDCT) scan was performed using a hybrid system alongside diagnostic invasive coronary angiography (ICA) without the additional use of a contrast agent, and demonstrated an excellent correlation in the infarct area compared with histopathologic specimens. In the present investigation, we evaluated the feasibility and diagnostic accuracy of a myocardial viability assessment by DE-MDCT using a hybrid system comprising ICA and MDCT alongside diagnostic ICA without the additional use of a contrast agent...

Amabiko is a lytic subcluster BE2 bacteriophage that infects Streptomyces scabiei -a bacterium causing common scab in potatoes. Its 131,414 bp genome has a GC content of 49.5% and contains 245 putative protein-coding genes, 45 tRNAs, and one tmRNA. Amabiko is closely related to Streptomyces bacteriophage MindFlayer (gene content similarity: 86.5%).

The isolation and characterization of additional phages is crucial for adding reliable viral sequences with relevant biological information to viral databases. In this study, we present the complete genomes of two Arthrobacter phages obtained from different soil samples.

A lytic bacteriophage EF_RCK infecting Enterococcus faecalis was isolated from a water sample collected in a raw cockle storage container at Taman Ria market, Sungai Petani, Malaysia. The phage has a 57,848-bp double-stranded DNA genome harboring 107 protein-encoding genes and shares 90.9% nucleotide similarity with Enterococcus phage EFKL ( Saphexavirus genus).

We sequenced the genome of a hirame novirhabdovirus isolate recovered from a white bass ( Morone chrysops ). Hirame novirhabdoviruses are in the genus Novirhabdovirus , along with infectious hematopoietic necrosis virus and viral hemorrhagic septicemia virus. This detection highlights that the full host range of rhabdoviruses in fish is not fully understood.

Microbes play a significant role in the cleanup of xenobiotic contaminants. Based on metagenomes derived from long-term enrichment cultures grown on xenobiotic solvents, we report 166 metagenome-assembled genomes, of which 137 are predicted to be more than 90% complete. These genomes broaden the representation of xenobiotic degraders.

We are reporting a Babesia bovis genome containing four nuclear chromosomes, a mitochondrial genome, and an apicoplast from reference isolate NVSL348. This report includes a gapless assembly consisting of all six genetic molecules.

Butyrivibrio are anaerobic bacteria and members of the family Lachnospiraceae with important roles in fiber digestion in both animals and humans. This report describes the complete genome of Butyrivibrio fibrisolvens type strain D1T (DSM 3071) consisting of a chromosome (CP146963), megaplasmid (pNP243), and small plasmid (pNP21).

Clostridium butyricum DKU-11, a bacterium has been isolated from the stools of breastfed infants near Cheonan-Asan city, Republic of Korea, and has a genome sequence of 4,630,814 bp. The GC content is 28.7% and a total of 4,137 coding sequences in two contigs.

We report four Chitinophaga sp. strains isolated from wastewater collected onboard the International Space Station. Here, we present three finished and one draft genome. Taxonomic ranks established by genome-based analysis indicate that these Chitinophaga sp. strains represent candidates for a new species.

Rivers are critical ecosystems that impact global biogeochemical cycles. Nonetheless, a mechanistic understanding of river microbial metabolisms and their influences on geochemistry is lacking. Here, we announce metaproteomes of river sediments that are paired with metagenomes and metabolites, enabling an understanding of the microbial underpinnings of river respiration.

Previously identified under the single designation of Aerococcus urinae , three distinct taxonomic species have been distinguished as Aerococcus loyolae, Aerococcus mictus, and Aerococcus tenax . Here, we present the complete genome sequences of the type strains of these species assembled via a combination of short-read and long-read sequencing techniques.Registered at ClinicalTrials.gov (NCT01166438).

Two ranavirus isolates were recovered from anuran and salamander samples collected during an amphibian mass mortality event in North-Central Florida in 2021. Phylogenetic analyses of the full genomes confirmed that the two isolates were nearly identical and strains of the species Frog virus 3 .

We report complete genome sequences of 14 severe acute respiratory syndrome coronavirus 2 Omicron sub-lineage JN.1 obtained from Bangladeshi individuals between 19 December 2023 and 21 January 2024.

The expression level of individual proteins varies markedly during the progression of the growth phase in bacteria. A set of proteins was quantified in Escherichia coli total proteome during 14 days of batch cultivation using pulse stable isotope labeled amino acids in cell culture (SILAC)-based quantitative mass spectrometry.

Moyamoya disease (MMD) is a rare neurological condition characterized by brain blood vessel narrowing, leading to collateral vessel formation. Diagnosis typically involves cerebral angiography and magnetic resonance angiography (MRA), with surgical revascularization often providing superior outcomes. Here, we present the case of a 55-year-old woman with hypertension, diabetes, and a history of ischemic stroke. She recently experienced a hemorrhagic stroke due to MMD, compounded by a non-functional pituitary macroadenoma...
