Abstract Eleven antidiabetic traditional Chinese medicine (TCM) extracts rich in saponins were examined for their antioxidant and antiglycation activities. The activities of these evaluated by studying the inhibition lipid peroxidation rat liver microsomes induced ascorbate/Fe 2+ , cumine hydroperoxide (CHP) or CCl 4 /reduced form nicotinamide‐adenine dinucleotide phosphate (NADPH). capacities also scavenging 2,2′‐diphenyl‐1‐picrylhydrazyl (DPPH) free radical. hemoglobin‐ δ ‐gluconolactone (...

Our previous study has demonstrated that the antidiabetic activity of extract root bark Aralia taibaiensis (EAT) was correlated with its combined antioxidant and antiglycation properties. To confirm further constituents responsible, 12 triterpenoid saponins were isolated from EAT examined for their activities. The activities pure compounds evaluated by studying inhibition lipid peroxidation in rat liver microsomes induced ascorbate/Fe(2+), cumine hydroperoxide (CHP) or CCl(4)/reduced form...

Moderate traumatic brain injury (mTBI) is a heterogeneous entity that poorly defined in the literature. Patients with mTBI have high rate of neurological deterioration (ND), which usually accompanied by poor prognosis and no definitive methods to predict. The purpose this study develop validate prediction model estimates ND risk patients using data collected on admission. Data for 479 retrospectively our department were analyzed logistic regression models. Bivariable identified variables p <...

In a prior study of intracerebral hemorrhage monitoring using magnetic induction phase shift (MIPS), we found that MIPS signal changes occurred to those seen with intracranial pressure. However, the characteristic alert is not yet fully explained. Combining brain physiology and theory, propose cerebrospinal fluid (CSF) may be primary factor leads hematoma expansion being alerted by earlier than pressure monitoring. This paper investigates relationship between CSF in rabbit models, which...

Abstract Objectives To investigate the association of eight variants four matrix metalloproteinase (MMP) genes with ischemic stroke (IS) and whether interactions among these single nucleotide polymorphisms (SNPs) increases risk IS. Methods Among 547 patients 350 controls, matrix‐assisted laser desorption/ionization time flight mass spectrometry was used to examine arising from different genes, including MMP‐1 (rs1799750), MMP‐2 (rs243865, rs2285053, rs2241145), MMP‐9 (rs17576), MMP‐12...

Rehabilitation of patients is closely related to immunity improvement, while almost all anticancer drugs kill leukocytes, one kind important immune cell, silence the system. Therefore, it particularly protect leukocytes in process cancer chemotherapy. In this work, a sequential drug release for synergistic treatment and promotion has been constructed. Firstly, hyperbranched glycidol (HPG) was synthesized by cationic ring-opening polymerization. Benefiting from existence many hydroxyl...

Closed cerebral hemorrhage (CCH) is a common symptom in traumatic brain injury (TBI) patients who suffer intracranial with the dura mater remaining intact. The diagnosis of CCH prior to hospitalization and early stage disease can help get earlier treatments that improve outcomes. In this study, noncontact, portable system for TBI-induced detection was constructed measures magnetic induction phase shift (MIPS), which associated mean conductivity caused by ratio between liquid (blood/CSF...

A novel method was developed based on near-field coupling phase shift (NFCPS) to perform non-contact and bedside monitoring of cerebral edema in the intensive care unit (ICU). total 17 subjects were selected conduct real-time NFCPS divided into surgical group, conservative group control group. The data collected at an interval 12 h, until patients left ICU for various reasons, such as being transferred general ward or discharged from hospital. Continuous collection conducted 15 min each time...

Abstract Background To investigate the feasibility of intracranial pressure (ICP) monitoring after traumatic brain injury (TBI) by electromagnetic coupling phase sensing, we established a portable shift (ECPS) test system and conducted comparison with invasive ICP. Methods TBI rabbits’ model were all synchronously monitored for 24 h ECPS testing We investigated abilities to detect targeted ICP feature extraction traditional classification decision algorithms.

Down-sampling Fourier single-pixel imaging is typically achieved by truncating the spectrum, where exclusively low-frequency coefficients are extracted while discarding high-frequency components. However, truncation of spectrum can lead to an undesired ringing effect in reconstructed result. Moreover, original necessitated grayscale basis patterns for illumination. This requirement limits speed because digital micromirror devices (DMDs) generate at a lower refresh rate. In order solve above...

摘要: 该文提出了一种将不变特征与谱匹配方法相结合的点模式匹配算法。该算法首先提出一种新的基于点集的不变特征相对形状上下文，然后利用点集间相对形状上下文的统计检验匹配测度来定义新的相容性度量，并以此为基础构造分配图及其亲近矩阵。最后利用分配图亲近矩阵的主特征向量以及匹配约束条件来实现点模式匹配问题的求解。模拟仿真与真实数据实验验证了该文算法的有效性和鲁棒性。 关键词: 点模式匹配 / 相对形状上下文 分配图 谱匹配方法
