FAPs orchestrate homeostasis of muscle physiology and pathophysiology.

As a common clinical manifestation, muscle weakness is prevalent in people with mobility disorders. Further studies of muscle weakness have found that patients with muscle weakness present with persistent muscle inflammation, loss of muscle fibers, fat infiltration, and interstitial fibrosis. Therefore, we propose the concept of muscle microenvironment homeostasis, which explains the abnormal pathological changes in muscles through the imbalance of muscle microenvironment homeostasis.

Association Between Multimorbidity and Depression in Older Adults: Evidence From Six Large Longitudinal Cohorts.

Background: Multimorbidity may increase the risk of depression in older adults, but the global average effect of multimorbidity on depression remains unknown. This research aimed to exclude the regional heterogeneity to quantify the exposure-response association between multimorbidity and depression in older adults worldwide.

Method: We collected 23,947 participants aged 65 years or above from six large prospective cohorts from developed and developing countries, including Mexico, South Korea, Europe, America, China, and England.

Neoadjuvant Modified Infusional Fluorouracil, Leucovorin, and Oxaliplatin With or Without Radiation Versus Fluorouracil Plus Radiation for Locally Advanced Rectal Cancer: Updated Results of the FOWARC Study After a Median Follow-Up of 10 Years.

We present 10-year results of the phase Ⅲ FOWARC trial, which evaluated the efficacy of modified infusional fluorouracil, leucovorin, and oxaliplatin (mFOLFOX6) with or without radiation compared with fluorouracil with radiation in patients with locally advanced rectal cancer. A total of 495 patients age 18-75 years with stage Ⅱ-Ⅲ rectal cancer were randomly assigned to three treatment arms: fluorouracil plus radiotherapy, mFOLFOX6 plus radiotherapy, or mFOLFOX6 alone, followed by surgery and adjuvant chemotherapy. With a median follow-up of 10 years, the 10-year disease-free survival (DFS) rates were 52.

A multi-antigen vaccinia vaccine broadly protected mice against SARS-CoV-2 and influenza A virus while also targeting SARS-CoV-1 and MERS-CoV.

Introduction: Coronaviruses and influenza viruses are significant respiratory pathogens that cause severe disease burdens and economic losses for society. Due to their diversity and evolution, vaccines typically require periodic updating to remain effective. An additional challenge is imposed by the possible coinfection of SARS-CoV-2 and influenza, which could increase disease severity.

Chinese guidelines for minimally invasive donor hepatectomy in living donor liver transplantation (2024 edition).

Background: Minimally invasive surgeries are increasingly central to modern medicine, particularly in liver transplantation. These techniques, which offer reduced trauma, precise operations, minimal bleeding, and swift recovery, are, however, unevenly adopted across China. Only a limited number of centers routinely perform minimally invasive donor hepatectomies, indicating a significant imbalance in the development and application of these advanced procedures.

Atractylenolide-III restrains cardiac fibrosis after myocardial infarction via suppression of the RhoA/ROCK1 and ERK1/2 pathway.

Background: Cardiac fibrosis, a critical factor in myocardial remodeling post-myocardial infarction (MI), can advance heart failure progression. Atractylenolide III (ATL-III), derived from Atractylodes lancea, has recognized antioxidant and anti-inflammatory effects; however, its influence on cardiac fibrosis remains unclear.

Methods: MI was induced in mice by permanent ligation of the left anterior descending (LAD) coronary artery, followed by 2 weeks of ATL-III or dimethyl sulfoxide (DMSO) treatment.

π-HuB: the proteomic navigator of the human body.

The human body contains trillions of cells, classified into specific cell types, with diverse morphologies and functions. In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies.

Recent progress of principal techniques used in the study of Müller glia reprogramming in mice.

In zebrafish, Müller glia (MG) cells retain the ability to proliferate and de-differentiate into retinal progenitor-like cells, subsequently differentiating into retinal neurons that can replace those damaged or lost due to retinal injury. In contrast, the reprogramming potential of MG in mammals has been lost, with these cells typically responding to retinal damage through gliosis. Considerable efforts have been dedicated to achieving the reprogramming of MG cells in mammals.

Multifactorial influences on childhood insomnia: Genetic, socioeconomic, brain development and psychopathology insights.

Insomnia is the most prevalent sleep disturbance during childhood and can result in extensively detrimental effects. Children's insomnia involves a complex interplay of biological, neurodevelopmental, social-environmental, and behavioral variables, yet remains insufficiently addressed. This study aimed to investigate the multifactorial etiology of childhood insomnia from its genetic architecture and social-environmental variables to its neural instantiation and the relationship to mental health.

Interleukin-4 promotes the clearance of amyloid-β by monocyte through enhancing the recognition and intracellular processing of amyloid-β.

Background: Impaired clearance of amyloid-β protein (Aβ) in the peripheral system is a crucial event in the pathogenesis of sporadic Alzheimer's disease (AD). Dysfunctional monocytes with deficient clearance of Aβ and increased secretion of pro-inflammatory factors in the periphery are considered to contribute to AD development. Multiple studies suggest that IL-4 can inhibit the inflammatory response and enhance the expression and activity of cathepsin protease associated with intracellular clearance of Aβ by monocytes.

4D computed tomography assessment of ruptured triple-lumen type B aortic dissection: a case report.

Background: Few studies have investigated the effect of the intimal morphology of type B aortic dissection (TBAD) on the blood flow after rupture. We report a case of a 30-year-old male with complicated TBAD, who underwent assessment with 4D computed tomography (4D-CT).

Case Summary: Patient presented with chest tightness for 14 days, a heart rate of 67 b.

Development of a nomogram for high antibody titre of COVID-19 convalescent plasma.

This study aimed to develop a predictive tool for identifying individuals with high antibody titers crucial for recruiting COVID-19 convalescent plasma (CCP) donors and to assess the quality and storage changes of CCP. A convenience sample of 110 plasma donors was recruited, of which 75 met the study criteria. Using univariate logistic regression and random forest, 6 significant factors were identified, leading to the development of a nomogram.

Gut microbiota regulate insomnia-like behaviors via gut-brain metabolic axis.

Sleep interacts reciprocally with the gut microbiota. However, mechanisms of the gut microbe-brain metabolic axis that are responsible for sleep behavior have remained largely unknown. Here, we showed that the absence of the gut microbiota can alter sleep behavior.

A novel hybrid model for predicting tertiary lymphoid structures and targeted immunotherapy outcomes in hepatocellular carcinoma: a multicenter retrospective study.

Objective: To develop a novel hybrid model for preoperative prediction of tertiary lymphoid structures (TLSs) of hepatocellular carcinoma (HCC), and to identify patients who may benefit from postoperative targeted immunotherapy.

Methods: Retrospective data were gathered from 332 patients with HCC who underwent surgical resection and gadoxetate disodium (Gd-EOB-DTPA) enhanced MRI at two tertiary hospitals (training cohort, n = 205; internal validation cohort, n = 90; and external validation cohort, n = 37) between March 2020 and January 2023. Radiomic features were extracted from Gd-EOB-DTPA-enhanced MRI sequences.

Association of Chronic Periodontitis with Hemorrhagic Stroke: A Systematic Review and Meta-Analysis.

Periodontitis is a chronic, multifactorial inflammatory condition linked to dysbiotic plaque biofilms and characterized by the gradual destruction of the structures supporting the teeth owing to compromised immune system function. Hemorrhagic stroke, which primarily occurs within the brain tissue or in the subarachnoid space as a blood leak of ruptured vessels, is a sudden neurological impairment caused by vascular damage in the central nervous system, resulting in focal neurological deficits. Chronic periodontitis (CP) and hemorrhagic stroke may share common pathogenic features involving inflammation and immune system activation, prompting researchers to investigate their potential connection.

Ferroptosis exacerbates the clonal deletion of virus-specific exhausted CD8 T cells.

During chronic infection or tumorigenesis, persistent antigen stimulation contributes to the exhaustion of CD8 T cells. Nevertheless, exhausted CD8 T (T) cells still preserve certain effector function, and maintaining a reservoir of exhausted cells is of vital importance for virus elimination and tumor eradiation. Despite considerable work interrogating the rejuvenation of T cells, mechanisms underpinning the clonal deletion of T cells remain largely unexplored over the past decade.

Alterations of gut virome with close interaction in the progression of estrogen deficiency-induced osteoporosis.

Previous research has established a link between gut microbiota and osteoporosis (OP) advancement. However, there remains a limited understanding of the crucial contribution of the gut virome in the onset and progression of OP. We employed metagenomic shotgun sequencing and gut virome sequencing to process the ovariectomy (OVX)-induced OP murine model, which revealed significant disparities in bacteriome and virome compositions between subjects with OP and healthy controls.
