Article Abstract

Summary: The AGP format is a tab-separated table format describing how components of a genome assembly fit together. A standard submission format for genome assemblies is a fasta file giving the sequence of contigs along with an AGP file showing how these components are assembled into larger pieces like scaffolds or chromosomes. For this reason, many scaffolding software pipelines output assemblies in this format. However, although many programs for assembling and scaffolding genomes read and write this format, there is currently no published software for making edits to AGP files when performing assembly curation. We present agptools, a suite of command-line programs that can perform common operations on AGP files, such as breaking and joining sequences, inverting pieces of assembly components, assembling contigs into larger sequences based on an AGP file, and transforming between coordinate systems of different assembly layouts. Additionally, agptools includes an API that writers of other software packages can use to read, write, and manipulate AGP files within their own programs.

Availability And Implementation: Source code and binaries freely available for download at https://github.com/WarrenLab/agptools, implemented in Python and supported on all operating systems.

Background: This study sought to investigate the prevalence, correlates, and network structure of the manifested symptoms in gambling disorder (GD) among methamphetamine (MA) use disorder (MUD) patients in China.

Methods: We interviewed 1069 patients using the Semi-Structured Assessment for Drug Dependence and Alcoholism (SSADDA), Chinese version. Besides MA and other substance use disorders, GD was also ascertained by SSADDA.

Article Synopsis
  • Dual immune checkpoint blockade (ICB) using CTLA4 and PD-(L)1 inhibitors shows improved anti-tumor effectiveness and immune toxicity compared to PD-(L)1 inhibitors alone in advanced non-small-cell lung cancer (NSCLC) patients.
  • Patients with mutations in STK11 and/or KEAP1 genes benefit more from the combination treatment compared to those receiving only PD-(L)1 inhibitors, as shown in the POSEIDON trial.
  • The loss of KEAP1 serves as a strong predictor for the success of dual ICB, as it leads to a more favorable outcome by changing the tumor's immune environment to better engage CD4 and CD8 T cells for anti-tumor activity. *

Department of Psychiatry, Third Hospital of Shanxi Medical University, Shanxi Bethune Hospital, Shanxi Academy of Medical Sciences, Tongji Shanxi Hospital, Taiyuan, 030032, China.

Introduction: Bipolar disorder (BD) is a chronic psychiatric disorder that combines hypomania or mania and depression. The study aims to investigate the research areas associated with cognitive function in bipolar disorder and identify current research hotspots and frontier areas in this field.

Methodology: Publications related to cognitive function in BD from 2012 to 2022 were searched on the Web of Science Core Collection (WoSCC) database.

Selective and brain-penetrant HCN1 inhibitors reveal links between synaptic integration, cortical function, and working memory.

Hyperpolarization-activated and cyclic-nucleotide-gated 1 (HCN1) ion channels are proposed to be critical for cognitive function through regulation of synaptic integration. However, resolving the precise role of HCN1 in neurophysiology and exploiting its therapeutic potential has been hampered by minimally selective antagonists with poor potency and limited in vivo efficiency. Using automated electrophysiology in a small-molecule library screen and chemical optimization, we identified a primary carboxamide series of potent and selective HCN1 inhibitors with a distinct mode of action.
