Human monkeypox, caused by monkeypox virus, has spread unprecedentedly to more than 100 countries since May 2022. Here we summarized the epidemiology of monkeypox through a literature review and elucidated the risks and elimination strategies of this outbreak mainly based on the summarized epidemiology. We demonstrated that monkeypox virus became more contagious and less virulent in 2022, which could result from the fact that the virus entered a special transmission network favoring close contacts (i.

Article Synopsis
  • * Analyzed 65 AEG samples and 10 normal tissues; findings show significantly reduced E-cadherin in AEG tissues, correlating with tumor differentiation, infiltration depth, and cancer stage.
  • * Results indicate that low E-cadherin expression is linked to lower 5-year survival rates and suggests it could serve as an early biomarker for AEG patient outcomes.

Geographical, environmental and pollution conditions affect facial skin health, but their effects on skin appearance have not been elucidated. This study aimed to describe the skin barrier and skin tone characteristics of Chinese subjects according to lifestyle and environmental conditions using in vitro measurements. In total, 1092 women aged 22-42 years were recruited from 7 representative Chinese cities.

Crotonaldehyde (CRA)-one of the major environmental pollutants from tobacco smoke and industrial pollution-is associated with vascular injury (VI). We used proteomics to systematically characterize the presently unclear molecular mechanism of VI and to identify new related targets or signaling pathways after exposure to CRA. Cell survival assays were used to assess DNA damage, whereas oxidative stress was determined using colorimetric assays and by quantitative fluorescence study; additionally, cyclooxygenase-2, mitogen-activated protein kinase pathways, Wnt3a, β-catenin, phospho-ErbB2, and phospho-ErbB4 were assessed using ELISA.

Article Synopsis
  • * STAT3 is activated through various pathways and promotes cancer growth by regulating genes that aid in cell proliferation and drug resistance.
  • * Non-coding RNAs like miRNAs, lncRNAs, and circRNAs are crucial in modulating the STAT3 pathway, and targeting STAT3 with specific drugs offers potential new treatments for EC.

Background: To explore if chest high-resolution computed tomography (HRCT) can make higher accurate stages for thoracic sarcoidosis stage than X-ray (CRX) only.

Methods: Clinical data from medical records of consecutive patients with a confirmed diagnosis of pulmonary sarcoidosis at Shanghai Pulmonary Hospital from January 1 2012 to December 31 2016 and consecutive patients treated at the Sarcoidosis Center of University of Cincinnati Medical Center, Ohio, USA from January 1 2010 to December 31 2015 were reviewed. The clinical records of 227 patients diagnosed with sarcoidosis (140 Chinese and 87 American) were reviewed.

The interstitial cells in bladder lamina propria (LP-ICs) are believed to be involved in sensing/afferent signaling in bladder mucosa. Transient receptor potential (TRP) cation channels act as mechano- or chemo-sensors and may underlie some of the sensing function of bladder LP-ICs. We aimed to investigate the molecular and functional expression of TRP channels implicated in bladder sensory function and Piezo1/Piezo2 channels in cultured LP-ICs of the human bladder.

Glucocorticoid (GC) hormone has been commonly used to treat systemic inflammation and immune disorders. However, the side effects associated with long-term use of high-dose GC hormone limit its clinical application seriously. GC hormone that can specifically target the lung might decrease the effective dosage and thus reduce GC-associated side effects.

Pulmonary fibrosis (PF) is a chronic and progressively fatal disease, but clinically available therapeutic drugs are limited due to efficacy and side effects. The possible mechanism of pulmonary fibrosis includes the damage of alveolar epithelial cells II (AEC2), and activation of immune cells such as macrophages. The ions released from bioceramics have shown the activity in stimulating soft tissue derived cells such as fibroblasts, endothelia cells and epithelia cells, and regulating macrophage polarization.

Organic-inorganic hybrid perovskite-type multiferroics have attracted considerable research interest owing to their fundamental scientific significance and promising technological applications in sensors and multiple-state memories. The recent achievements with divalent metal dicyanamide compounds revealed such malleable frameworks as a unique platform for developing novel functional materials. Herein, two 3D organic-inorganic hybrid perovskites [Et P(CH ) F][Mn(dca) ] (1) and [Et P(CH ) Cl][Mn(dca) ] (2) (dca=dicyanamide, N(CN) ) are presented.

Background: Acute exacerbation of IPF (AE-IPF) is associated with high mortality. We studied changes in pathogen involvement during AE-IPF and explored a possible role of infection in AE-IPF.

Objectives: Our purpose is to investigate the role of infection in AE-IPF.

We use the simultaneous application and testing method to detect Mycobacterium tuberculosis rRNA (SAT-TB) with the endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) biopsy specimens to differentiate sputum-negative tuberculosis from sarcoidosis. In the first part, we validated the SAT-TB on the bronchial or EBUS-TBNA biopsy specimens from sputum smear-positive pulmonary tuberculosis. In the second part, all EBUS-TBNA specimens for sputum smear-negative intrathoracic tuberculous lymphadenopathies or sarcoidosis were tested with the SAT-TB, acid-fast bacilli smear, and culture.

Both 3D organic-inorganic perovskites ([Et3P(CH2)2Cl][Cd(dca)3] (1) and [Et3P(CH2)2F][Cd(dca)3] (2) [dca = dicyanamide, N(CN)2-]) display two sequentially reversible high-temperature phase transitions and switchable dielectric properties. Through halogen substitution, 1 shows exceptional switching behaviour of second harmonic generation effects and remarkably 2 represents the first above-room-temperature 3D ferroelastic material characterized by two ferroelastic phases.

Background: Patients with idiopathic pulmonary fibrosis (IPF) often experience acute exacerbation (AE) after an episode of common cold.

Aims: To establish a mouse model of virus infection-induced AE-IPF and investigate the mechanism underlying the AE-IPF.

Methods: Herpes simplex virus 1 (HSV1) was inoculated intranasally to wild-type (WT) and IL-17A gene knockout (IL-17A ) mice 21 days after intratracheal administration of bleomycin (BLM).

The stimulator of interferon genes (STING) is a key adaptor protein mediating innate immune defense against DNA viruses. To investigate the role of STING in acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF), we isolated primary peripheral blood mononuclear cells (PBMCs) from patients and healthy controls (HCs).

Although numerous studies have examined the neurotoxicity of acrylamide in adult animals, the effects on neuronal development in the embryonic and lactational periods are largely unknown. Thus, we examined the toxicity of acrylamide on neuronal development in the hippocampus of fetal rats during pregnancy. Sprague-Dawley rats were mated with male rats at a 1:1 ratio.

The advent of nanomedicine requires novel delivery vehicles to actively target their site of action. Here, we demonstrate the development of lung-targeting drug-loaded liposomes and their efficacy, specificity and safety. Our study focuses on glucocorticoids methylprednisolone (MPS), a commonly used drug to treat lung injuries.

Article Synopsis
  • This study explores the use of a nanobody (Nb) designed to target and deliver drugs specifically to the lungs by binding to a protein called human pulmonary surfactant protein A (SP-A).
  • Researchers developed a special library of Nbs through a process called biospanning and successfully identified Nb4, which has a strong binding affinity for human SP-A tissues and does not interact with other organ cells.
  • In experiments with mice and rats, Nb4 showed quick lung accumulation after injection and minimal toxicity over short periods, suggesting it could be a safe and effective method for drug delivery to the lungs.
