Pathogen spectrum and clinical characteristics of lung cancer patients: A 10-year retrospective study.

Infection is the most common non-cancer cause of death in patients with lung cancer (LC). However, original research reports with large sample sizes on the epidemiology, pathogen spectrum, immune status changes, and prognosis of these patients are lacking. A retrospective study of LC patients with infection was performed at Guangxi Medical University Cancer Hospital from 2014 to 2023.

Four new species of Agraphydrus Régimbart (Coleoptera: Hydrophilidae), with additional faunistic records for China.

Four new species of Agraphydrus Régimbart are described from China: Agraphydrus danxiaensis sp. nov. from Guangdong, A.

Comparison of the clinical features of HIV-positive and HIV-negative hosts infected with Talaromyces marneffei: A multicenter, retrospective study.

Objectives: Talaromyces marneffei is an emerging pathogen, and the number of infections in HIV-negative individuals is rapidly increasing. Nevertheless, there is no sufficient comprehensive report on this issue, and awareness needs to be raised among clinicians.

Methods: We analyzed the differences in the clinical data of patients who are HIV-negative and HIV-positive with Talaromyces marneffei infection (TMI) from 2018 to 2022.

Transgenic Arabidopsis thaliana plants expressing a β-1,3-glucanase from sweet sorghum (Sorghum bicolor L.) show reduced callose deposition and increased tolerance to aluminium toxicity.

Seventy-one cultivars of sweet sorghum (Sorghum bicolor L.) were screened for aluminium (Al) tolerance by measuring relative root growth (RRG). Two contrasting cultivars, ROMA (Al tolerant) and POTCHETSTRM (Al sensitive), were selected to study shorter term responses to Al stress.

[Aluminum lightens the adverse effects of excessive Mn on growth of soybean (Glycine max)].

The influence of aluminum (Al) on physiological and biological characteristics of soybean under manganese (Mn) stress was investigated. The results showed that Al suppressed the transport of Mn to shoots (Fig.2B, C), and subsequently alleviated the inhibition of shoot growth (Fig.

[Manganese uptake and transportation as well as antioxidant response to excess manganese in plants].

Manganese (Mn) is an essential micronutrient throughout all stages of plant development. Mn plays an important role in many metabolic processes in plants. It is of particular importance to photosynthetic organisms in the chloroplast of which a cluster of Mn atoms at the catalytic centre function in the light-induced water oxidation by photosystem II, and also function as a cofactor for a variety of enzymes, such as Mn-SOD.

[Organic acid secretion and its detoxification mechanism in plant roots under aluminum stress].

Phytotoxicity of Al is becoming one of the most serious problems in limiting plant growth on acid soils. Under Al stress, a number of plant species, cultivars or genotypes exhibit inheritable tolerance by organic acid secretion which is specific to Al stress and localized to the root apex. Citric acid, oxalic acid and malic acid are thought to be the most effective organic acids in detoxifying Al.

The risk factors of nosocomial infection in severe craniocerebral trauma.

Objective: To explore the risk factors of nosocomial infection in severe craniocerebral trauma and the way of prevention.

Methods: The clinical data of 387 patients with severe craniocerebral trauma were reviewed.

Results: The total nosocomial infection rate of this study was 22.
