The accumulation, elimination characteristics, and toxic effects of intertidal sediment crude oil contamination in Sinonvacula constricta.

Marine oil spills lead to intertidal sediment pollution, causing benthic bioaccumulation and toxicity. However, relatively few studies have been conducted on the effects of crude oil sediment pollution on benthos. In this study, Sinonovacula constricta was used as the research object in a sediment environment to study the accumulation and elimination effects of S.

Camrelizumab vs Placebo in Combination With Chemotherapy as Neoadjuvant Treatment in Patients With Early or Locally Advanced Triple-Negative Breast Cancer: The CamRelief Randomized Clinical Trial.

Importance: Preferred neoadjuvant strategies for early or locally advanced triple-negative breast cancer include a 4-drug chemotherapy regimen containing anthracyclines, cyclophosphamide, taxanes, and platinum. Blockade of the programmed death receptor 1/ligand-1 (PD-1/PD-L1) pathway may improve efficacy of classic neoadjuvant chemotherapy. Camrelizumab, an anti-PD-1 antibody, has showed antitumor activity in advanced triple-negative breast cancer.

Risk association model for atelectasis complication in pneumonia patients following standardized treatment.

Background: pneumonia (MPP) is a common disease of childhood pneumonia, and atelectasis is a serious comorbidity. Traditional diagnostic methods for MPP are limited by low accuracy, emphasizing the need for improved diagnostic approaches. This study aimed to establish a predictive scoring model for early detection of MPP complicated with atelectasis following standardized treatment.

Morphogenesis and regeneration share a conserved core transition cell state program that controls lung epithelial cell fate.

Transitional cell states are at the crossroads of crucial developmental and regenerative events, yet little is known about how these states emerge and influence outcomes. The alveolar and airway epithelia arise from distal lung multipotent progenitors, which undergo cell fate transitions to form these distinct compartments. The identification and impact of cell states in the developing lung are poorly understood.

Exemplifying interspecies variation of liposome fate by the effects of anti-PEG antibodies.

The different fate of liposomes among species has been discovered and mentioned in many studies, but the underlying mechanisms have not been explored. In the present work, we concentrated on the fate of PEGylated liposomes (sLip) in three commonly used species (mice, rats, and dogs). It was exhibited that the accelerated blood clearance (ABC) phenomenon and hypersensitivity in large animals (beagle dogs) were much more significant than that in rodents.

Boosted Na-MnO supercapacitor performance via strong metal support interaction.

MnO is widely utilized as an electrode material in supercapacitors. However, overcoming challenges such as sluggish ion migration, aggregate tendency, and low conductivity is imperative for optimizing MnO-based supercapacitors. Herein, NaMnO was employed as the Mn precursor to introducing a higher concentration of small Na ions into the layer structure of δ-MnO.

From Optical Fiber Communications to Bioimaging: Wavelength Division Multiplexing Technology for Simplified in vivo Large-depth NIR-IIb Fluorescence Confocal Microscopy.

Near-infrared II (NIR-II, 900-1880 nm) fluorescence confocal microscopy offers high spatial resolution and extensive in vivo imaging capabilities. However, conventional confocal microscopy requires precise pinhole positioning, posing challenges due to the small size of the pinhole and invisible NIR-II fluorescence. To simplify this, a fiber optical wavelength division multiplexer (WDM) replaces dichroic mirrors and traditional pinholes for excitation and fluorescence beams, allowing NIR-IIb (1500-1700 nm) fluorescence and excitation light to be coupled into the same optical fiber.

Identification and Targeting of Regulators of SARS-CoV-2-Host Interactions in the Airway Epithelium.

Although the impact of SARS-CoV-2 in the lung has been extensively studied, the molecular regulators and targets of the host-cell programs hijacked by the virus in distinct human airway epithelial cell populations remain poorly understood. This is in part ascribed to the use of nonprimary cell systems, overreliance on single-cell gene expression profiling that does not ultimately reflect protein activity, and bias toward the downstream effects rather than their mechanistic determinants. Here we address these issues by network-based analysis of single cell transcriptomic profiles of pathophysiologically relevant human adult basal, ciliated and secretory cells to identify master regulator (MR) protein modules controlling their SARS-CoV-2-mediated reprogramming.

A longitudinal study on the development trajectory of auditory processing and its relationship with language development in Chinese preschool children with autism spectrum disorder: study protocol.

Background: It was reported that more than 96% of autism spectrum disorder (ASD) children are accompanied with different degrees of sensory processing abnormalities, and up to 50% of ASD children exhibit abnormal auditory response. Studies have confirmed that some ASD children's abnormal auditory response may be related to their abnormal auditory processing. Prior research demonstrated that ASD children's auditory processing has high heterogeneity, thus, ASD children's auditory processing may have different developmental trajectories.

Broad cross neutralizing antibodies against sarbecoviruses generated by SARS-CoV-2 infection and vaccination in humans.

The outbreaks of severe acute respiratory syndrome coronavirus (SARS-CoV-1), Middle East respiratory syndrome coronavirus (MERS-CoV), and SARS-CoV-2 highlight the need for countermeasures to prevent future coronavirus pandemics. Given the unpredictable nature of spillover events, preparing antibodies with broad coronavirus-neutralizing activity is an ideal proactive strategy. Here, we investigated whether SARS-CoV-2 infection and vaccination could provide cross-neutralizing antibodies (nAbs) against zoonotic sarbecoviruses.

T cell exhaustion methylation signature drives differential immune responses in glioblastoma.

Background: Methylation-related signatures play crucial roles in tumorigenesis and progression. However, their roles in the immune response in primary glioblastoma (GBM) remains unclear.

Methods: We analyzed the differential expression of specific members of T cell exhaustion-related pathways in GBM from the perspective of T cell exhaustion.

Light-phase time-restricted feeding disrupts the muscle clock and insulin sensitivity yet potentially induces muscle fiber remodeling in mice.

Skeletal muscle plays a critical role in regulating systemic metabolic homeostasis. It has been demonstrated that time-restricted feeding (TRF) during the rest phase can desynchronize the suprachiasmatic nucleus (SCN) and peripheral clocks, thereby increasing the risk of metabolic diseases. However, the impact of dietary timing on the muscle clock and health remains poorly understood.

Puerarin ameliorates colitis by direct suppression of macrophage M1 polarization in DSS mice.

Background: Ulcerative colitis (UC) is a type of inflammatory bowel disease primarily affecting the colon and rectum. The clinical symptoms of UC include persistent diarrhea, abdominal pain, and rectal bleeding, with chronic inflammation often limited to the mucosal layer of the colon. Macrophages play a significant role in the pathogenesis of UC in response to the presence of gut microbiota.
