[Effects of Photovoltaic Power Station Construction on Terrestrial Environment： Retrospect and Prospect].

With the rapid growth of global energy consumption, the environment will further deteriorate, and the competition among countries to reduce emissions will become more intense. Photovoltaic power generation using solar energy as a clean energy source is of strategic importance for achieving a carbon-neutral planet. Therein, centralized photovoltaic power stations in terrestrial ecosystems cover the earth's surface, which leads to changes in land use and has a significant effect on the surface energy balance and precipitation regimes, altering soil nutrient cycling and plant productivity, and ultimately significantly affects ecosystem functions and services.

Evaluation and Use of Organs from Donors Poisoned by Organophosphorus Pesticide.

BACKGROUND The aim of this study was to explore the evaluation and use of donor organs from donors with brain death caused by acute severe organophosphorus pesticides and provide a basis for the use of such donor organs. MATERIAL AND METHODS Seven cases of brain dead donors caused by acute organophosphorus pesticide poisoning from January 2014 to December 2018 in the hospital were collected, and a retrospective analysis was made of the donors' age, race, physiological and pathological changes, donor organ function changes and the organ use, liver or kidney function recovery, and complications of the recipients. The 18 recipients were followed up until June 31, 2022.

Regulatory Patterns of Crp on Monensin Biosynthesis in .

Monensin, produced by Streptomyces cinnamonensis, is a polyether ionophore antibiotic widely used as a coccidiostat and a growth-promoting agent in agricultural industry. In this study, cyclic AMP receptor protein (Crp), the global transcription factor for regulation of monensin biosynthesis, was deciphered. The overexpression and antisense RNA silencing of crp revealed that Crp plays a positive role in monensin biosynthesis.

Evaluation and application of donors with primary central nervous system tumors.

Background: This study aimed to explore the safety of donors with primary central nervous system tumors for kidney and liver transplantations.

Methodology: Clinical data of 29 donors with primary CNS tumors in January 2007 to December 2017, as well as the follow-up data of 16 liver transplant recipients and 46 kidney transplant recipients, were analyzed. According to the risk factors, the high-risk group was classified as Group 1, the low-risk factors were classified as Group 2, and the unknown risk group was classified as Group 3.

Clinical analysis of percutaneous computed tomography-guided injection of cyanoacrylate for localization of 115 small pulmonary lesions in 113 asymptomatic patients.

Objective: This study was performed to assess the clinical feasibility, safety, and effectiveness of a computed tomography (CT)-guided cyanoacrylate injection system and investigate the relationship between clinical features and pathologic characteristics of diminutive pulmonary lesions.

Methods: In total, 115 pulmonary nodules from 113 patients (63 female, 50 male) with a diameter of <20 mm were percutaneously localized with a CT-guided cyanoacrylate injection system and then resected.

Results: Of the pure ground-glass opacities (GGOs), 16.

Induction of apoptosis and autophagy by calcifying nanoparticles in human bladder cancer cells.

Calcifying nanoparticles have been linked to various types of human disease, but how they contribute to disease processes is unclear. Here, we examined whether and how calcifying nanoparticles isolated from patients with kidney stones are cytotoxic to human bladder cancer cells. Calcifying nanoparticles were isolated from midstream urine of patients with renal calcium oxalate stones and examined by electron microscopy.

[Response of Soil Respiration and Organic Carbon to Returning of Different Agricultural Straws and Its Mechanism].

Soybean, maize and rice straws were selected as raw materials to study the response of the soil respiration (SR) and soil organic carbon (SOC) to returning of different straws in the Chongming Dongtan area. The results showed that all of SR, SOC and the plant biomass of the lands with returning of different straws were higher than those of the controls. The soil with soybean straw returning possessed the lowest SR and highest SOC among the three kinds of straws, meaning its higher soil organic carbon sequestration capability than corn and maize straws returning.

Communities of ammonia oxidizers at different stages of Spartina alterniflora invasion in salt marshes of Yangtze River estuary.

Spartina alterniflora, an aggressive invasive plant species at the estuarine wetlands of China's coasts, has become a major threat to the natural ecosystems. To understand its potential influence on nitrification processes, the community structures and abundance of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) were investigated using 454-pyrosequencing and quantitative real-time PCR (qPCR) in S. alterniflora invading salt marsh sediments at the Yangtze River estuary in Chongming island, Shanghai, China.

Pancreatic metastasis of papillary thyroid carcinoma: a case report with review of the literature.

In this article we give a case report on a PTC patient with pancreatic metastasis. In this case, the patient was admitted to our hospital for recurrence of PTC and occupying pancreatic lesions. We considered that the pancreatic neoplasm may be pancreatic metastasis of PTC but there is no previous experience about therapeutic approaches to this type of metastases.

Resveratrol attenuates left ventricular remodeling in old rats with COPD induced by cigarette smoke exposure and LPS instillation.

The objective of this study was to investigate left cardiac damage and the cardioprotective effects of resveratrol in old rats with COPD. Rats 22 months old were divided into three groups: control (CTL), smoking and lipopolysaccharides (SM/LPS), and SM/LPS plus resveratrol (SM/LPS-Res). Cardiac function, pathology, oxidative stress, and apoptosis index were measured.

Malignant perivascular epithelioid cell tumor of the retroperitoneum.

Perivascular epithelioid cell tumors (PEComas) are a rare type of mesenchymal neoplasms characterized by a proliferation of perivascular cells with an epithelioid phenotype and expression of myo-melanocytic markers. The majority of PEComas seem to be benign and usually their prognosis is good. Malignant cases are extremely rare, exhibiting a malignant course with local recurrences and distant metastases.

Effects of Spartina alterniflora invasion on the communities of methanogens and sulfate-reducing bacteria in estuarine marsh sediments.

The effect of plant invasion on the microorganisms of soil sediments is very important for estuary ecology. The community structures of methanogens and sulfate-reducing bacteria (SRB) as a function of Spartina alterniflora invasion in Phragmites australis-vegetated sediments of the Dongtan wetland in the Yangtze River estuary, China, were investigated using 454 pyrosequencing and quantitative real-time PCR (qPCR) of the methyl coenzyme M reductase A (mcrA) and dissimilatory sulfite-reductase (dsrB) genes. Sediment samples were collected from two replicate locations, and each location included three sampling stands each covered by monocultures of P.

Sonographically guided transthoracic biopsy of peripheral lung and mediastinal lesions: role of contrast-enhanced sonography.

Objectives: The purpose of this study was to assess the impact of contrast-enhanced sonography on sonographically guided transthoracic needle biopsy of lung lesions.

Methods: A total of 121 patients underwent sonographically guided transthoracic needle cutting biopsy. Of the 121 patients, 62 (contrast-enhanced sonography group) underwent contrast-enhanced sonography before biopsy, and the information from contrast-enhanced sonography was used to optimize the biopsy procedure.
