OsNCED5 confers cold stress tolerance through regulating ROS homeostasis in rice.

Cold stress is one of the most serious abiotic stresses that affects the growth and yield in rice. However, the molecular mechanism by which abscisic acid (ABA) regulates plant cold stress tolerance is not yet clear. In this study, we identified a member of the OsNCED (9-cis-epoxycarotenoid dioxygenase) gene family, OsNCED5, which confers cold stress tolerance in rice.

An ABA biosynthesis enzyme gene OsNCED4 regulates NaCl and cold stress tolerance in rice.

Rice (Oryza sativa L.) is susceptible to various abiotic stresses, such as salt, cold, and drought. Therefore, there is an urgent need to explore the relevant genes that enhance tolerance to these stresses.

Bacterial diversity and its correlation with sensory quality of two types of zha-chili from Shennongjia region, China.

In the Shennongjia region of China, two types of zha-chili with distinct flavors exist: the first type (P zha-chili) uses a significant amount of chili pepper but no potato, while the other (PP zha-chili) contains a smaller amount of chili pepper but a proportion of potato. In order to investigate the bacterial diversity and sensory properties of these two types of zha-chili, this study employed a combination of amplicon sequencing, culture-based methods, and sensory technology. The results of the study showed statistically significant differences (P < 0.

Determination of Glomerular Filtration Rate with CT Measurement of Renal Clearance of Iodinated Contrast Material versus Tc-DTPA Dynamic Imaging "Gates" Method: A Validation Study in Asymmetrical Renal Disease.

Purpose To validate a computed tomographic (CT) glomerular filtration rate (GFR) measurement and compare it with renal dynamic imaging GFR obtained by using the "Gates" method, with dual plasma sampling technetium 99m (Tc) diethylenetriaminepenta-acetic acid (DTPA) clearance ("true GFR") as the reference standard. Materials and Methods This prospective study was approved by the institutional review board, and written informed consent was obtained from all patients. Forty-two patients with unilateral renal disease were included.

A Simplified Whole-Organ CT Perfusion Technique with Biphasic Acquisition: Preliminary Investigation of Accuracy and Protocol Feasibility in Kidneys.

Purpose: To determine the feasibility and accuracy of a protocol for calculating whole-organ renal perfusion (renal blood flow [RBF]) and regional perfusion on the basis of biphasic computed tomography (CT), with concurrent dynamic contrast material-enhanced (DCE) CT perfusion serving as the reference standard.

Materials And Methods: This prospective study was approved by the institutional review board, and written informed consent was obtained from all patients. Biphasic CT of the kidneys, including precontrast and arterial phase imaging, was integrated with a first-pass dynamic volume CT protocol and performed and analyzed in 23 patients suspected of having renal artery stenosis.

Differentiation of malignant and benign pulmonary nodules with first-pass dual-input perfusion CT.

Objective: To assess diagnostic performance of dual-input CT perfusion for distinguishing malignant from benign solitary pulmonary nodules (SPNs).

Methods: Fifty-six consecutive subjects with SPNs underwent contrast-enhanced 320-row multidetector dynamic volume CT. The dual-input maximum slope CT perfusion analysis was employed to calculate the pulmonary flow (PF), bronchial flow (BF), and perfusion index [Formula: see text].

Lung cancer perfusion: can we measure pulmonary and bronchial circulation simultaneously?

Objective: To describe a new CT perfusion technique for assessing the dual blood supply in lung cancer and present the initial results.

Methods: This study was approved by the institutional review board. A CT protocol was developed, and a dual-input CT perfusion (DI-CTP) analysis model was applied and evaluated regarding the blood flow fractions in lung tumours.

[Diagnosis of pleural cavity extraskeletal osteosarcoma: a case report and literature review].

Objective: To describe the manifestations and diagnosis of pleural cavity extraskeletal osteosarcoma (ESO).

Methods: One case of ESO diagnosed at the Research Institute of Tuberculosis, 309th Hospital of PLA was reported. Six cases reported in the literature were reviewed.

Insertion of PCB to treat traumatic cervical intervertebral disc herniation.

Objective: To evaluate the clinical effect of PCB (a new anterior cervical instrumental system combining an intradiscal cage with an integrated plate) in treating traumatic cervical intervertebral disc herniation.

Methods: Anterior decompression and PCB internal fixation were used in 22 patients with traumatic cervical intervertebral disc herniation. They were followed up from 3 to 16 months and analyzed by symptom and image data.
