心前区监测血浆清除率测定肾有效血流量

Zhongshan Daxue xuebao. Yixue kexue ban, 1982
自应用放射性示踪剂测定肾血流量以来,曾建立了多种测定方法,但多较繁琐,须连续抽血和收集尿液。1968年Razzak等介绍了在体外监测血浆清除率测定肾血流量的简便方法。我们参考此法,结合本室条件,测定了82例肾有效血浆流量（ERPF）和肾有效血流量（ERBF）,并根据对同位素肾图的定量分析计算分侧肾血流量。结果报告如下。

Using MALDI‐FTICR Mass Spectrometry to Enhance ZooMS Identifications of Pleistocene Bone Fragments Showing Variable Collagen Preservation

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Recent advances in high‐throughput molecular analyses of collagen peptides, especially ZooMS (Zooarchaeology by Mass Spectrometry), have permitted breakthroughs in the analysis of archaeological material that is highly fragmented, a factor that hinders morphological identification.

Deep Brain Stimulation Reduces Conflict‐Related Theta and Error‐Related Negativity in Patients With Obsessive–Compulsive Disorder

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Obsessive–compulsive disorder (OCD) is a psychiatric disorder with alterations of cortico‐striato‐thalamo‐cortical loops and impaired performance monitoring. Electrophysiological markers such as conflict‐related medial frontal theta (MFT) and error‐related negativity (ERN) may be altered by clinically effective deep brain ...

Inferring Brown Bear Hair Snare Interactions by Automatically Detecting Bipedalism on Camera Trap Images Using Pose Estimation and a Multilayer Perceptron

Remote Sensing in Ecology and Conservation, EarlyView.
This study proposes an automated method to infer brown bear hair snare interactions by detecting bipedal behavior in camera‐trap images using a pose estimation model and a multilayer perceptron (MLP). A YOLO‐based model, fine‐tuned from humans and dogs to a custom dataset, achieved high performance (≈93% keypoint precision and ≈96% classification ...

Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for

Tourism as a driver of economic and social development in underdeveloped regions

Regional Science Policy &Practice, EarlyView., 2023
Abstract Cross‐border cooperations have been usually approached by developing trade agreements between international regions to upgrade their socioeconomic conditions and promote international tourism flows in territories. However, little attention has been paid to the role that tourist companies play in underprivileged territories highly dependent on ...

The effects of dietary supplementation with fish oil on renal function in cyclosporine-treated renal transplant recipients

, 1990
The effect of a daily supplementation of 6 g fish oil (30% C20:5 omega-3 (EPA) and 20% C22:6 omega-3 for three months on renal function variables was investigated in a placebo-controlled (6 g corn oil, 50% C18:2 omega-6) prospective, randomized, double ...

糖皮质激素加重对激素不敏感儿童肾病蛋白尿

Zhongshan Daxue xuebao. Yixue kexue ban, 1999
目的: 有报道糖皮质激素( GCs)亦可加重肾脏病蛋白尿。本课题旨在探讨 GCs 是否加重激素不敏感肾病综合征 ( NS)蛋白尿及其机制, 以指导临床合理使用 GCs。方法: 19 例对激素不敏感的 NS 患儿予泼尼松每日 1. 5～ 2 mg/kg 隔日早上 08∶ 00顿服。同时检测激素日和无激素日的尿蛋白及其成分、白蛋白和免疫球蛋白 G 及肌酐的清除率、肾有效血浆流量 ( ERPF)、尿前列腺素等并进行比较。结果: 与无激素日比较, 激素日尿蛋白明显增加( 2. 4 g±0. 5 g vs 1.

Bradykinin and renal function in normal man: effects of adrenergic blockade

, 1965
Renal function was studied in five normal subjects during the infusion of bradykinin at 0.1 and 0.4 µg/kg per min, and in four additional normal subjects during the infusion of norepinephrine at dosages beginning with 1–3 µg/ min.
