The safety and efficacy of the fissure-first approach in lung segmentectomy for patients with incomplete fissures.

Background: Lung segmentectomy has gained much more attention as an important surgical method for treating early-stage lung cancer. However, incomplete fissures increase the difficulty of lung segmentectomy. The aim of this study was to analyze the safety and efficacy of the fissure-first approach in precision resection of lung segments for patients with incomplete fissures.

Challenging Diagnosis: Unmasking the Enigma of Imaging Findings with Lung Schwannomas.

Schwannomas are benign slow-growing tumors arising from the embryonic neural crest cells of the nerve sheaths of peripheral and cranial nerves, and they are a rare type of soft tissue mass that is usually always solitary. Generally, it grows in the head, neck, and flexor portions of the limbs, where many nerves are located. Schwannomas of the lung are extremely rare.

First report of Leptosphaeria biglobosa 'brassicae' causing leaf spots in Eutrema japonicum in Yunnan, China.

Wasabi (Eutrema japonicum) is a root vegetable that is cultivated at large scales in southwestern China. In November 2021, approximately 40% of plants in a forested plantation in Dadishui, Yunnan Province, China (25.47°N, 103.

A new Panax notoginseng Leaf Spot Caused by Boeremia linicola in Yunnan, China.

Panax notoginseng-also known as Tianqi and Sanqi-is one of the most highly valued medicinal perennial herbs in the world (Wang et al. 2016). In August 2021, leaf spot was observed on P.

2,3-Butanediol from the leachates of pine needles induces the resistance of to the leaf pathogen .

Compared with the use of monocultures in the field, cultivation of medicinal herbs in forests is an effective strategy to alleviate disease. Chemical interactions between herbs and trees play an important role in disease suppression in forests. We evaluated the ability of leachates from needles of to induce resistance in leaves, identified the components via gas chromatography-mass spectrometry (GC-MS), and then deciphered the mechanism of 2,3-Butanediol as the main component in the leachates responsible for resistance induction via RNA sequencing (RNA-seq).

[Modification of quicklime on acid soil under forest and their effect on the growth of ].

Soil acidification is an important factor leading to poor growth and root rot disease of in the understorey of forests. In this study, different amounts of quicklime (0, 500, 1000, 1500 and 2000 kg·hm) were amended into acid soil under forest. We evaluated the effect of quikelime addition on soil chemical properties, phenols, rhizosphere microorganisms and growth of .

Appropriate Soil Heat Treatment Promotes Growth and Disease Suppression of by Interfering with the Bacterial Community.

In our greenhouse experiment, soil heat treatment groups (50, 80, and 121°C) significantly promoted growth and disease suppression of in consecutively cultivated soil (CCS) samples ( < 0.01), and 80°C worked better than 50°C and 121°C ( < 0.01).

First report of Meloidogyne arenaria infecting Maidong (Ophiopogon japonicus) in China.

Maidong (Ophiopogon japonicus) is a perennial evergreen plant of the Asparagaceae, occurring mainly in China, Japan, Vietnam, and India. It grows in the damp place on the hillside below 2000 meters above sea level, under the forest or beside the stream;It has been widely cultivated in the Sichuan ofhina for medicinal uses; and it is included in the Chinese Pharmacopoeia. During April 2019, Maidong plants exhibiting symptoms of stunting, leaf wilting, and multiple galls in the roots associated with root-knot nematode (Meloidogyne sp.

Appropriate nitrogen application enhances saponin synthesis and growth mediated by optimizing root nutrient uptake ability.

Background: Cultivation of medicinal crops, which synthesize hundreds of substances for curative functions, was focused on the synthesis of secondary metabolites rather than biomass accumulation. Nutrition is an important restrict factor for plant growth and secondary metabolites, but little attention has been given to the plasticity of nutrient uptake and secondary metabolites synthesis response to soil nitrogen (N) change.

Methods: Two year-field experiments of Sanqi (), which can synthesize a high level of saponin in cells, were conducted to study the effects of N application on the temporal dynamics of biomass, nutrient absorption, root architecture and the relationships between these parameters and saponin synthesis.

Anastomotic leakage after intrathoracic versus cervical oesophagogastric anastomosis for oesophageal carcinoma in Chinese population: a retrospective cohort study.

Objective: To investigate the characteristics and predictors for anastomotic leakage after oesophagectomy for oesophageal carcinoma from the perspective of anastomotic level.

Design: Retrospective cohort study.

Settings: A single tertiary medical centre in China.

Baseline sensitivity and resistance-risk assessment of Phytophthora capsici to iprovalicarb.

Iprovalicarb has been used to control Phytophthora capsici, a devastating pathogen of many economically important crops. To evaluate the risk of fungicide resistance, 158 isolates of P. capsici were examined for sensitivity to iprovalicarb by measuring mycelial growth.

Flumorph Is a Novel Fungicide That Disrupts Microfilament Organization in Phytophthora melonis.

ABSTRACT The mechanism of the effects of flumorph (a novel fungicide) was investigated by analyzing alterations of hyphal morphology, cell wall deposition patterns, F-actin organization, and other organelles in Phytophthora melonis. Calcofluor white staining suggested that flumorph did not inhibit the synthesis of cell wall materials, but disturbed the polar deposition of newly synthesized cell wall materials during cystospore germination and hyphal growth. After exposure to flumorph, zoospores were able to switch into cystospores accompanied with the formation of a cell wall, whereas cystospores failed to induce the isotropic-polar switch and did not produce germ tubes but continued the isotropic growth phase.
