Unraveling compound curing agent on protein characteristics and proteome changes of Nuodeng ham by TMT-labeled quantitative proteomics.

To understand the effects of compound curing agent (60 % NaCl+40 % KCl + 90 mg/kg NaNO) on the protein characteristics and proteome of Nuodeng ham, the protein structure, oxidation, degradation, and proteomic changes of Nuodeng ham were analyzed. The results showed that the hydrophobic and disulfide bonds were the main forces to maintain the stability of the ham protein. The compound curing agent reduced protein oxidation and promoted the transformation of the α-helix structure to the β-sheet structure.

Diagnosis of pulmonary hemorrhagic leptospirosis complicated by invasive pulmonary aspergillosis complemented by metagenomic next-generation sequencing: a case report.

Background: Leptospirosis is a bacterial zoonosis with variable clinical manifestations. Pulmonary diffuse hemorrhagic leptospirosis often occurs rapidly and, when not promptly diagnosed and treated, it can be life-threatening. is an opportunistic fungus that is commonly seen in immunosuppressed patients.

TNF-α and HMGB1: New Biomarkers of Acute Pulmonary Embolism.

Objective: Inflammatory mediators have been implicated in the pathophysiology of acute pulmonary embolism (PE). However, the role of inflammatory mediator activation in the development of pulmonary embolism remains elusive. Here, we determined the reliability of the plasma levels of inflammatory markers tumor necrosis factor-alpha (TNF-α) and high mobility histone 1 (HMGB1) as diagnostic biomarkers of PE.

Development and validation of a novel risk assessment model to estimate the probability of pulmonary embolism in postoperative patients.

Pulmonary embolism (PE) is a leading cause of mortality in postoperative patients. Numerous PE prevention clinical practice guidelines are available but not consistently implemented. This study aimed to develop and validate a novel risk assessment model to assess the risk of PE in postoperative patients.

Clinical symptoms and related risk factors in pulmonary embolism patients and cluster analysis based on these symptoms.

Pulmonary embolism (PE) remains largely underdiagnosed due to nonspecific symptoms. This study aims to evaluate typical symptoms of PE patients, their related predictors, and to differentiate typical clusters of patients and principal components of PE symptoms. Clinical data from a total of 551 PE patients between January 2012 and April 2016 were retrospectively reviewed.

Eosinophilic biomarkers for detection of acute exacerbation of chronic obstructive pulmonary disease with or without pulmonary embolism.

Eosinophilia has been implicated in the pathophysiology of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). However, the role of eosinophil activation in the development of AECOPD remains unclear. In the present study, the reliability of plasma levels of eosinophil activation markers, including eosinophil cationic protein (ECP), major basic protein (MBP), eosinophil-derived neurotoxin (EDN) and eosinophil peroxidase (EPX), were measured and used as diagnostic biomarkers of AECOPD with or without pulmonary embolism (PE).

Evaluation of platelet distribution width in chronic obstructive pulmonary disease patients with pulmonary embolism.

Background: Platelets play an important role in the pathogenesis of pulmonary embolism (PE). We aimed to investigate whether there is a correlation between platelet distribution width (PDW) and chronic obstructive pulmonary disease (COPD) patients with PE.

Methods: We conducted a retrospective study using 126 COPD patients with PE and 51 COPD patients without PE.

Bird community comparisons of four plantations and conservation concerns in South China.

Plantations of non-native, fast-growing trees are increasing in the tropics and subtropics, perhaps with negative consequences for the native avifauna. We studied bird diversity in 4 types of plantations in South China to determine which plantation types are especially detrimental, and compared our findings with studies in nearby natural forests to assess the magnitude of the negative impact. A total of 57 species was recorded.

[Mercury concentration and its distribution in Nycticorax nycticorax and Chinese Ardeola bacchus fledglings at Huangpu District of Guangzhou City, China].

In this study, live fledglings of Nycticorax nycticorax and Ardeola bacchus at the Huangpu District of Guangzhou City were collected, and their primary feather, breast feather, tail feather, liver, chest muscle and egg shell were sampled for mercury determination. The results showed that these two heron species had a very similar distribution pattern of mercury concentration in their tissues and organs, i. e.
