Acute heart attack is associated with 30% mortality rate, among those 50% of death occur before arriving to a hospital. The ST elevated myocardial infarction (STEMI) and non-STEMI heart condition may lead to heart attack which can be prevented if detected ahead of time. 2D convolutional neural network (CNN) uses 2D data has been successfully applied to machine vision, plant disease diagnosis and medical field. Acquiring 2D images such as CT, MRI, and PET data can be prohibitively expensive. On the other hand, there are many 1D biomedical signals, such as ECG, that is more affordable and can be used for medical diagnosis of heart diseases as an example. The purpose of this paper is to propose the use of 1D CNN for medical diagnosis relying on more affordable 1D biomedical signal. To reduce the computational burden and enhance performance, the firefly algorithm (FA) is first applied to reduce the number of features needed for classification by the 1D CNN. The proposed 1D CNN combined with FA technique was applied to STEMI and Non-STEMI heart attack diagnosis using ECG signals. The method was trained and tested using A clinically available synchronously acquired ECG signal database from physionet was used to train and evaluate the performance of the proposed technique. The correctly classified outcome using FACNN is 84.84% with kappa statistics of .693, while average performance from other popular machine learning algorithm were 78.54% correctly classified outcome and kappa statistics of .56.
急性心脏病发作与30%的死亡率相关,其中50%的死亡发生在到达医院之前。ST段抬高型心肌梗死(STEMI)和非STEMI型心脏病可导致心脏病发作,如果及早发现是可以预防的。二维卷积神经网络(CNN)利用二维数据已成功应用于机器视觉、植物病害诊断和医学等领域。获取二维图像,如CT、MRI和PET数据可能非常昂贵。另一方面,有许多一维生物医学信号,如ECG,价格更便宜,可以用于心脏疾病的医学诊断,例如。本文的目的是提出利用1D CNN依靠更实惠的1D生物医学信号进行医学诊断。为了减少计算量和提高性能,首先采用萤火虫算法(firefly algorithm, FA)来减少1D CNN分类所需的特征数量。将提出的1D CNN结合FA技术应用于STEMI和Non-STEMI心电诊断。该方法使用临床可用的从physionet同步获取的心电信号数据库进行训练和测试,以训练和评估所提出技术的性能。使用FACNN的分类结果正确率为84.84%,kappa统计量为0.693,而其他流行的机器学习算法的分类结果正确率为78.54%,kappa统计量为0.56。

The study was performed to assess the impact of Biofield Treated test item (DMEM medium) on Human Endothelial Hybrid Cell Line (EA. hy926) for the expression of cyclic guanosine monophosphate (cGMP). The test item was divided into three parts. The first part was received one-time Consciousness Energy Treatment by a renowned Biofield Energy Healer, Mahendra Kumar Trivedi and labeled as BT-I, while second part received two-times Biofield Treatment and is denoted as BT-II. The third part did not receive any types of treatment and denoted as untreated DMEM. The level of intracellular cGMP in the BT-I and BT-II groups showed a significantly (p≤0.001) increased by 296.06% and 339.37%, respectively in Ea. hy926 cells compared to the untreated DMEM group. These results suggest that BT-II group showed a significant improved the level of cGMP with respect to the BT-I group. Therefore, the Biofield Energy Healing Treatment can be used to treat the erectile dysfunction patients along with other associated disorders such as orgasmic disorders, frotteuristic disorder, female sexual arousal disorder, vaginismus, fetishistic disorder, sex addiction, hypoactive sexual desire disorder, premature or delayed ejaculation.

Hyperglycemia, often accompanied with various complications such as chronic ulcers, represents a major socio-economic health problem. Dipeptidyl peptidase IV or CD26 molecule (DPP IV/CD26), is an omnipresent transmembrane protein with significant involvements in different physiological and pathological processes. It has been recognized as a therapeutic option in the treatment of hyperglycemia, especially in patients suffering from type 2 diabetes, given its capability to regulate the biological activity of incretins, which are major regulators of glucose homeostasis. Furthermore, DPP IV/CD26 has been indicated to be involved in the regulation of inflammatory processes as well as cell proliferation and angiogenesis. New scientific evidence shows that inhibition of DPP IV/CD26 leads to a more efficacious healing of chronic ulcers in diabetic patients as well as in mice models of wounded tissue restoration. However, the role of DPP IV/CD26 in the process of wound healing in hyperglycemia is not entirely known. Our aim was to summarize most important findings on the involvement of DPP IV/CD26 in the regulation of glycemia as well as tissue regeneration and reparation. This work reviews basic biochemical.
高血糖通常伴有慢性溃疡等各种并发症,是一个主要的社会经济健康问题。二肽基肽酶IV或CD26分子(DPP-IV/CD26)是一种普遍存在的跨膜蛋白,显著参与不同的生理和病理过程。鉴于其调节肠促胰岛素生物活性的能力,它已被公认为治疗高血糖的一种治疗选择,尤其是在2型糖尿病患者中,肠促胰岛素是葡萄糖稳态的主要调节因子。此外,DPP-IV/CD26已被证明参与炎症过程以及细胞增殖和血管生成的调节。新的科学证据表明,抑制DPP-IV/CD26可以更有效地治愈糖尿病患者以及损伤组织修复小鼠模型中的慢性溃疡。然而,DPPIV/CD26在高血糖伤口愈合过程中的作用尚不完全清楚。我们的目的是总结DPPIV/CD26参与血糖调节以及组织再生和修复的最重要发现。这项工作回顾了基本的生物化学。

We here researched the features of transport of nerve impulse along the nerve fiber using modern theory of molecular biology, in which we first elucidate the properties of structure of the nerve cell and the features of distribution of the charges for the sodium ions and potassium ions in the inner and exterior of the never cell membranes. In practice, their distributions are not uniformity, where the distribution of sodium ions and potassium ions between the inner and exterior of cell-membranes are not same, they are just inverse. Just so, an action electro-potential occurs in the cell-membranes. However, the action electro-potential is only a static impulse, it cannot propagate along the nerve organizations. If the nerve organizations are acted by the bio-energy, which could lead to the periodic variation of these sodium ions and potassium ions in the inner and exterior of the never cell membranes can be varied periodically under the action of bio-energy by the works of sodium pump and potassium pump on the surface of cell membrane, then the nerve impulse can propagate along the nerve fiber cell membranes. Our investigations verify that the bioenergy released from the hydrolyses reaction of adenosine phosphate (ATP) molecules in the cells can play the role. This chemical reaction can release the bio-energy of o.42 eV, which can be transported along the protein molecules to excite the work of se sodium pump and potassium pump. Thus, the propagation of the nerve impulse can be carried out automatically in living systems. This is just the mechanism of propagation of the nerve impulse along the nerve l fiber cel membrane. In this paper we elucidate and research in detain and deeply the mechanism of form of the nerve impulse and its features of propagation.
本文运用现代分子生物学理论研究了神经冲动沿神经纤维的传递特征,首次阐明了神经细胞的结构特性以及钠离子和钾离子在神经细胞膜内外的电荷分布特征。在实践中,它们的分布是不均匀的,其中钠离子和钾离子在细胞膜内外的分布是不相同的,它们只是相反的。就这样,细胞膜上产生了动作电位。然而,动作电位只是一个静态脉冲,它不能沿神经组织传播。如果神经组织受到生物能的作用,就会导致细胞膜内外钠离子和钾离子的周期性变化,在生物能的作用下,通过细胞膜表面的钠泵和钾泵的作用,这些钠离子和钾离子会周期性变化,神经冲动就会沿着神经纤维细胞膜传播。我们的研究证实,细胞中磷酸腺苷(ATP)分子水解反应释放的生物能可以发挥作用。该化学反应可释放0.42 eV的生物能,该生物能可沿蛋白质分子运输,激发硒钠泵和钾泵的工作。因此,神经冲动的传播可以在生命系统中自动进行。这就是神经冲动沿着神经纤维细胞膜传播的机制。本文对神经冲动的形成机制及其传播特征进行了深入的阐述和研究。

Kinetics and efficacy of photo-activated crosslink for tissue-engineering 光活化交联在组织工程中的动力学与性能

We will review the kinetics, applications and efficacy of light-activated crosslink. The crosslink efficacy is influenced by multiple factors including: the applied light intensity, exposure period and dose, the initial concentration profiles of photosensitizers (PS) and oxygen, the quantum yield of the PS triplet state, the kinetic rate constants of PS (in type-I) and oxygen concentration (in typeII). Lower light intensity (I0) and higher PS concentration (C0) provides higher efficacy, but also suffers more toxicity to the cells. Higher light intensity (I0) may accelerate the crosslink but has lower efficacy (for the same dose). Therefore, optimal ratio of C0/ I0 is required for accelerated and safe crosslink. Safety issue also limits the maximum dose can be applied to the collagen, besides the limitation of PS concentration. Three important issues are presented: improvement of the crosslink speed (via higher light intensity) and efficacy of crosslink, and the role of photosensitizer (photo initiator) concentration.
我们将综述光活化交联的动力学、应用和功效。交联效果受到多种因素的影响,包括:施加的光强度、暴露时间和剂量、光敏剂(PS)和氧的初始浓度分布、PS三重态的量子产率、PS的动力学速率常数(在I型中)和氧浓度(在II型中)。较低的光强度(I0)和较高的PS浓度(C0)提供了更高的功效,但对细胞的毒性也更大。较高的光强度(I0)可以加速交联,但具有较低的功效(对于相同剂量)。因此,C0/I0的最佳比例是加速和安全交联所必需的。除了PS浓度的限制外,安全性问题还限制了胶原蛋白的最大剂量。提出了三个重要问题:提高交联速度(通过更高的光强度)和交联效果,以及光敏剂(光引发剂)浓度的作用。

The crosslink efficacy is influenced by multiple factors including: the applied light intensity, exposure period and dose, the initial concentration profiles of photosensitizers (PS) and oxygen, the quantum yield of the PS triplet state, the kinetic rate constants of PS (in type-I) and oxygen concentration (in typeII). Lower light intensity (I0) and higher PS concentration (C0) provides higher efficacy, but also suffers more toxicity to the cells. Higher light intensity (I0) may accelerate the crosslink but has lower efficacy (for the same dose). Therefore, optimal ratio of C0/ I0 is required for accelerated and safe crosslink.
