Introduction And Objectives: Recent randomized controlled trials support the use of intravascular imaging-guided percutaneous coronary intervention (PCI) to improve patient prognosis. However, the subsequent risk of clinical events in patients with coronary artery disease is not determined solely by lesion characteristics or how these lesions are treated. The current study investigated whether the effects of intravascular imaging in complex PCI vary according to atherothrombotic risks.

Article Synopsis
  • - Recent outbreaks of pathogens have led researchers to explore graphene as a potential antimicrobial agent due to its low toxicity and effective interaction with bacteria, making it attractive for antimicrobial applications.
  • - Integrating graphene into copper coatings can enhance their antimicrobial effects, but challenges in uniformly distributing graphene within the copper matrix have limited practical use; Cu-doped graphitic nanoplatelets (CuGnPs) offer a possible solution to this issue.
  • - Studies demonstrated that CuGnPs significantly reduced the survival of Staphylococcus aureus compared to controls, indicating that copper combined with graphene oxide can improve bacterial inhibition effectiveness.

Immunostaining is an essential biological technique that determines the localization and level of target antigen molecules using antibodies within cells or tissues. Here, we present a brief guide to immunostaining, including the principles, methods, and different types of immunostaining. This manuscript will also provide common challenges and optimization strategies.

The Patagonian toothfish (Dissostichus eleginoides) belongs to the Actinopterygii class, and the suborder Notothenioidei, which lives in cold waters in the Southern Hemisphere. We performed assembly and annotation, and we integrated the Illumina short-read sequencing for polishinng, PacBio long-read sequencing for contig-level assembly, and Hi-C sequencing technology to obtain high-quality of chromosome-level genome assembly. The final assembly analysis resulted in a total of 495 scaffolds, a genome size of 844.

Thought-action fusion (TAF) is the metacognitive belief that the power of thoughts can have real-life consequences, often inducing unpleasant inner experiences and recruiting coping strategies such as rumination. Therefore, this study aimed to investigate the neural correlates of TAF and their associations with rumination in depression. A total of 37 patients with major depressive disorder (MDD) and 37 healthy controls (HCs) underwent functional magnetic resonance imaging with a TAF induction task and psychological assessments.

Article Synopsis
  • * Fifty patients were monitored using both types of devices simultaneously, assessing their agreement through statistical methods.
  • * Results showed that while heart rate readings were consistent between the devices, some technical measurements had disagreements, but overall, the single-lead ECG is a reliable alternative for monitoring heart activity during exercise.

Background: Early-stage lung cancers detected by low-dose computed tomography (CT) often require confirmation through invasive procedures due to the absence of endobronchial lesions. This study assesses the diagnostic utility of bronchial washing fluid (BW) sequencing, a less invasive alternative, aiming to identify patient characteristics most suited for this approach.

Methods: From June 2017 to March 2018, we conducted a prospective cohort study by enrolling patients with incidental lung lesions suspected of early-stage lung cancer at two independent hospitals, and 114 were diagnosed with lung cancer while 50 were diagnosed with benign lesions.

Preservation of residual hearing and vestibular function is a crucial factor in cochlear implantation (CI), especially in patients with residual low-frequency hearing thresholds. We report a case of a patient who underwent unilateral endoscope-assisted CI with a challenging surgical view following rigorous posterior tympanotomy. A 53-year-old male presented with left-sided intractable tinnitus due to sudden sensorineural hearing loss that had occurred 10 years prior.

Article Synopsis
  • Brain entropy (BEN) measures information in brain activity and can help assess brain function, particularly in schizophrenia (SCZ) through resting-state fMRI studies.
  • This study investigates how reduced working memory capacity in SCZ relates to changes in BEN during high-demand tasks, specifically using data from an N-back task with 15 SCZ patients and 15 healthy controls (HC).
  • Results showed that SCZ patients had lower task BEN in key brain regions compared to HC, with reduced BEN correlating negatively with symptoms and task performance, suggesting that diminished BEN could be a potential neuroimaging marker for SCZ.

Background: Glutathione (GSH) is a crucial antioxidant in the human brain. Although proton magnetic resonance spectroscopy using the Mescher-Garwood point-resolved spectroscopy sequence is highly recommended, limited literature has measured cortical GSH using this method in major psychiatric disorders.

Methods: By combining magnetic resonance spectroscopy and resting-state functional magnetic resonance imaging, we quantified brain GSH and glutamate in the medial prefrontal cortex and precuneus and explored relationships between GSH levels and intrinsic neuronal activity as well as clinical symptoms among healthy control (HC) participants (n = 30), people with major depressive disorder (MDD) (n = 28), and people with obsessive-compulsive disorder (OCD) (n = 28).

Neuropathological features of Alzheimer's disease include amyloid plaques, neurofibrillary tangles and Lewy bodies, with the former preceding the latter two. However, it is not fully understood how these compound proteinopathies are interconnected. Here, we show that transplantation of amyloid-β oligomer-activated microglia into the striatum of naïve mice was sufficient to generate all the features of Alzheimer's disease, including widespread tauopathy and synucleinopathy, gliosis, neuroinflammation, synapse loss, neuronal death, and cognitive and motor deficits.

  • Northern temperate coniferous forests are important because they connect different types of forests, but they are facing problems from things like climate change and human activities.
  • Recent research focuses on how severe drought affects tree growth in these forests, studying specific species like Abies nephrolepis and Picea jezoensis.
  • Some trees recover well from drought, while others resist it better; however, the growth before a drought plays a big role in how they react, and new disturbances may happen because of climate change.

Background: Alcohol consumption is widely known to have detrimental effects on various organs and tissues. The effects of ethanol on male reproduction have been studied at the physiological and cellular levels, but no systematic study has examined the effects of ethanol on male reproduction-related gene expression.

Results: We employed a model of chronic ethanol administration using the Lieber-DeCarli diet.

Cellular senescence is a crucial biological process associated with organismal aging and many chronic diseases. Here, we present a brief guide to mammalian senescence assays, including the measurement of cell cycle arrest, change in cellular morphology, senescence-associated β-galactosidase (SA-β-gal) staining, and the expression of senescence-associated secretory phenotype (SASP). This work will be useful for biologists with minimum expertise in cellular senescence assays.

: Smoking cessation is acknowledged for its health benefits. However, it paradoxically increases diabetes mellitus (DM) risk shortly after quitting due to weight gain. This research aimed to investigate how smoking status could affect the development of DM, focusing on how the risk of acquiring diabetes changed over time after quitting smoking, independent of variables such as weight gain.

  • Childhood maltreatment negatively affects cognitive development in young adults, particularly impacting executive function, working memory, and processing speed.
  • The study involved 149 participants and used tests like the WAIS-IV to compare cognitive functions between those with and without maltreatment experiences.
  • Results showed that those with a history of maltreatment had lower cognitive performance and often used ineffective strategies to manage their emotions, suggesting the need for cognitive interventions to improve these skills.

Sexual dimorphism affects various biological functions, including immune responses. However, the mechanisms by which sex alters immunity remain largely unknown. Using as a model species, we showed that males exhibit enhanced immunity against various pathogenic bacteria through the upregulation of HLH-30 (Helix Loop Helix 30/TFEB (transcription factor EB)), a transcription factor crucial for macroautophagy/autophagy.
