A human adult consists of about 1015 cells; which divide and differentiate in order to refurbish organs and tissues [1]. However, if the cells do not stop dividing, they may lead to cancer. Characteristically, cancer is an uncontrolled proliferation of cells which become structurally abnormal and possess the ability to detach them from a tumor and establish a new tumor at a remote site [2]. Every year over 200,000 people are diagnosed with cancer in the United Kingdom only, and approximately 120,000 die as a result of this disease [2]. According to the International Agency for Research on Cancer, in 2002, cancer killed more than 6.7 million people around the world and another 10.9 million new cases were diagnosed [3]. According to World Health Organization, cancer is the second cause of death globally after cardiovascular diseases. An estimated 8.2 million people die from cancer each year, that represents 13% of all deaths worldwide. Cancer basically results from the uncontrolled rapid division of malignant cells that grow beyond their usual limits. Unlike normal cells, cancerous cells do not respond to the controlling signals and consequently, they grow and divide in an uncontrolled manner, infecting normal tissues and organs. There can be many different types of cancers. The type of the cell from where the tumors originate classifies the cancers. Cancers derived from epithelial cells of breast, prostate, lung, pancreas and colon, cause approximately 90% of all human deaths from cancer; lymphomas are cancers of the immune organs such as spleen, white blood cells and lymph glands; leukemias causes the cancers of blood forming bone marrow; while sarcomas are cancers of fibrous connective tissues of bone, cartilage, fat tissue, muscle and neurons; and germ cell tumors are derived from pluripotent stem cells presented in the testicles and ovary. Early detection and effective treatment can help to increase survival rates of cancer patients. So therefore, deliberative plans are needed to improve prevention and treatment of cancer. As we all know cancer rates continue to rise, particularly in the developed world, becoming one of the leading public health problems in many countries [4].

一个成年人由大约1015个细胞组成;它们通过分裂和分化来更新器官和组织。然而,如果细胞不停止分裂,它们可能会导致癌症。癌症是一种不受控制的细胞增殖,这些细胞在结构上变得异常,并具有与肿瘤分离并在远处建立新肿瘤的能力。仅在英国,每年就有超过20万人被诊断出患有癌症,大约有12万人死于这种疾病。根据国际癌症研究机构的数据,2002年,全球有670多万人死于癌症,另有1090万新病例被诊断为癌症。根据世界卫生组织的数据,癌症是仅次于心血管疾病的全球第二大死因。据估计,每年有820万人死于癌症,占全球死亡总人数的13%。癌症基本上是由恶性细胞不受控制的快速分裂导致的,这些细胞的生长超出了通常的极限。与正常细胞不同,癌细胞对控制信号没有反应,因此,它们以不受控制的方式生长和分裂,感染正常组织和器官。癌症有很多种。肿瘤产生的细胞类型对癌症进行了分类。源自乳腺、前列腺、肺、胰腺和结肠上皮细胞的癌症,约占人类癌症死亡总数的90%;淋巴瘤是免疫器官的癌症,如脾脏、白细胞和淋巴腺;白血病引起骨髓造血癌;肉瘤是骨、软骨、脂肪组织、肌肉和神经元纤维结缔组织的癌症;生殖细胞肿瘤来源于睾丸和卵巢中的多能干细胞。早期发现和有效治疗有助于提高癌症患者的存活率。因此,需要深思熟虑的计划来改善癌症的预防和治疗。众所周知,癌症发病率持续上升,特别是在发达国家,已成为许多国家的主要公共卫生问题之一。许多癌症都与寿命有关,而且随着个人预期寿命的增加,它们出现的可能性也会增加。宫颈癌(CC)是全世界妇女死亡的主要原因[6-8]。到目前为止所做的研究表明这种癌症

Mesenchymal stem cells (MSCs) have the characteristics of self-renewal, immune regulation and multipotency. Due to their multi-lineage differentiation potential [1], MSCs can be induced to differentiate into adipocytes, osteoblasts, chondrocytes, muscle cells, nerve cells, liver cells and pancreatic beta cells in vivo and in vitro. These characteristics make MSCs promising candidates for use in cell therapy and regenerative medicine [24]. MSCs were first described as stromal stem cells from the bone marrow that have a spindle shape in culture. However, although the bone marrow is considered the standard source for MSCs, MSCs isolated from other sources have different features in terms of surface markers, proliferation rates, and differentiation capability [5-7]. MSCs have been isolated from a number of other sources, such as adipose tissue, dental pulp, umbilical cord blood, and amniotic fluid [8-10]. One alternative source for MSCs is liver tissue. Scientists have isolated liver mesenchymal stem cells (LMSCs) from different species and attempted to characterize them in hopes that these cells could be a better alternative to bone marrow mesenchymal stem cells (BMSCs), especially for liver diseases [8]. One of the challenging aspects concerning MSCs in general is their characterization. In this mini-review, we will focus on studies that characterized LMSCs from different species, such as humans, mice, rats, rabbits, sheep, chickens and cattle. Human LMSCs and human BMSCs
间充质干细胞(MSCs)具有自我更新、免疫调节和多能性等特点。由于MSCs具有多系分化潜能,在体内和体外均可诱导分化为脂肪细胞、成骨细胞、软骨细胞、肌肉细胞、神经细胞、肝细胞和胰腺β细胞。这些特性使间充质干细胞在细胞治疗和再生医学中具有很大的应用前景。MSCs最初被描述为来自骨髓的基质干细胞,在培养中具有纺锤形。然而,尽管骨髓被认为是骨髓间充质干细胞的标准来源,但从其他来源分离的骨髓间充质干细胞在表面标记物、增殖率和分化能力方面具有不同的特征[5-7]。骨髓间充质干细胞已从许多其他来源分离出来,如脂肪组织、牙髓、脐带血和羊水[8-10]。肝组织是骨髓间充质干细胞的另一种来源。科学家们已经从不同物种中分离出肝间充质干细胞(LMSCs),并试图对其进行表征,希望这些细胞能够成为骨髓间充质干细胞(BMSCs)的更好替代品,特别是对于肝脏疾病而言。关于间充质干细胞的一个具有挑战性的方面是它们的特征。在这篇综述中,我们将重点介绍不同物种的研究,如人类、小鼠、大鼠、兔子、羊、鸡和牛。人骨髓间充质干细胞和人骨髓间充质干细胞

Genetic “bottlenecks” have long been understood to restrict the ability of a species to pass on its genetic traits to later generations. Such events occur when the numbers of one species are too small to pass on a full range of genes. Inevitably, an impoverished genome results, one that is prone to disease or to inbreeding. Now, however, a second effect of these bottlenecks is shown. Replication is the benthic standard for assessing genetic bottlenecks from wide stochastic studies. Unfortunately, this replication requirement may cause real genetic effects to be missed. A real result can fail to replicate for strategic reasons including benthic size or variability in strategic definitions across complex samples. In genome-wide strategic studies the genetic allowances of polymorphisms may differ due to sampling error or population RNA. We hypothesize that some statistically significant benthic genetic effects may fail to replicate in a complex informational set when strategic frequencies differ, and the functional polymorphism seems with one or more other diametric polymorphisms. To test this theory, we designed a simple study in which stochastic status grew by two interacting bottlenecks with data-irritability from 0.044 to 0.8 with dilatory sample sizes ranging from 400 to 1,700 individuals. We show that the need to replicate the united complex main effect of two polymorphisms can drop a little with a change of strategic distance of less than 0.1 at a semi-interacting polymorphism. We also show that differences in useful size can result in a reversal of meretricious effects where a benthic gene becomes a strategic factor in dilatory studies. Those stochastic data suggest that failure to replicate a complex bottleneck may provide strategic clues about the complexity of the underlying genetic sense. We think that morphisms that fail to replicate be checked for dilatory quirks with strategic units, particularly when taken from people with stochastic backgrounds or different geological regions.
长期以来,人们一直认为基因“瓶颈”限制了一个物种将其遗传特征传给后代的能力。当一个物种的数量太少而无法传递全部基因时,就会发生这种事件。不可避免地,会产生一个贫穷的基因组,一个容易生病或近亲繁殖的基因组。然而,现在,这些瓶颈的第二个影响已经显现出来。复制是从广泛的随机研究中评估遗传瓶颈的海底标准。不幸的是,这种复制要求可能会导致错过真正的遗传效应。由于战略原因,包括海底规模或复杂样本战略定义的可变性,真实的结果可能无法复制。在全基因组战略研究中,多态性的遗传容许量可能因采样错误或群体RNA而不同。我们假设,当策略频率不同时,一些具有统计学意义的海底遗传效应可能无法在复杂的信息集中复制,并且功能多态性似乎与一个或多个其他直径多态性有关。为了验证这一理论,我们设计了一项简单的研究,其中随机状态由两个相互作用的瓶颈增长,数据易激性从0.044到0.8,扩展样本量从400到1700人不等。我们表明,在半相互作用的多态性下,复制两个多态性的联合复合体主要效应的需要可能会略有下降,策略距离的变化小于0.1。我们还表明,有用大小的差异可以逆转个体自残效应,在拖延研究中,底栖基因成为一个战略因素。这些随机数据表明,未能复制复杂的瓶颈可能会为潜在遗传意义的复杂性提供战略线索。我们认为,无法复制的形态可以用战略单位来检查是否有拖沓的怪癖,特别是当从具有随机背景或不同地质区域的人身上提取时。

The basic objective of this research work is to evaluate the mechanism of action of compound Epigallocatechin, Epicatechin and Stigmasterol Phytosterol (Synergy), Aspidofractinine-3-methanol) and Terephthalic acid, dodecyl 2-ethylhexyl ester with Selected clinical isolates by using molecular biomarker MazEF9 TA system. Toxin-Antitoxin (TA) systems are highly conserved in members of the Gram positive +ve and Gram negative –ve bacteria which has been proposed to play an important role in physiology and virulence. Clinical microorganisms were cultured and Sub-culturing in Department of Microbiology and Centre for Biocomputing and Drug Development (CBDD), Adekunle Ajasin University, Akungba Akoko, Ondo-state, Nigeria. A 12 hours old culture of each microorganism was re-suspended in plant extract at 1000 μg mL in a total volume of 500μl for 0, 15, 30, 45, 60, and 180 minutes. The cells were pelleted by centrifugation at 5000 revolution for 5 minutes, to isolate the DNA and total RNA was quantified using spectrophotometric absorbance at 260nm, the DNA was removed with Turbo DNA-free (Ambion, Inc.). The Removal of DNA from the RNA samples was performed using DNA-freeTM DNA Removal Kit Reverse Transcription–PCR reaction in a 15.0μL final volume. 1μl template cDNA (~40ng) were combined with 1.0μL of forward primer (5nM), 1.0μL of reverse primer (5nM), 4.5mL nuclease-free water and 7.5μL of Taq 2X Master Mix. Assessment of Polymerase Chain Reaction products (amplicons) were electrophoresed in 0.5% of agarose gel using 0.5 × TBE buffer (2.6g of Tris base, 5g of Tris boric acid and 2mL of 0.5M EDTA and adjusted to pH 8.3 with the sodium hydroxide pellet) with 0.5μLethidum bromide. The bacteriostatic mechanism of action of isolated compounds A1, A3 and F3 from the Stem bark of Spondiasmombin. The bacteriostatic mechanism of action was demonstrated with the selected biomarker MazF against E. coli and B. subtilis. It was observed that at 30 minutes, the mechanism of action is bacteriostatic action on the test organism (B. subtilis). By overexpressing putative MazF homologues in clinical isolates (MazF9) induce bacteriostasis. MazFribo nucleases contribute synergistically to the ability of clinical isolates to adapt to conditions such as nutrient depletion and rapid progress to the death thereby measuring the reversible bacteriostatic mechanism of action of isolated novel compound from Spondiasmombin the novel compound is A1 (Epigallocatechin, Epicatechin and Stigmasterol phytosterol (synergy), A3(Aspidofractinine-3-methanol) and F3(terephthalic dodecyl 2-ethylhexyl ester) isolated from Spondiasmombin. The use of medicinal plant like Spondiasmombin should be encourage because of its therapeutic properties in the prophylaxis cure of infectious disease.

MazFribo nucleases contribute synergistically to the ability of clinical isolates to adapt to conditions such as nutrient depletion and rapid progress to the death thereby measuring the reversible bacteriostatic mechanism of action of isolated novel compound from Spondiasmombin the novel compound is A1 (Epigallocatechin, Epicatechin and Stigmasterol phytosterol (synergy), A3(Aspidofractinine-3-methanol) and F3(terephthalic dodecyl 2-ethylhexyl ester) isolated from Spondiasmombin. The use of medicinal plant like Spondiasmombin should be encourage because of its therapeutic properties in the prophylaxis cure of infectious disease.","PeriodicalId":93190,"journal":{"name":"International journal of cell science & molecular biology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48677063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wald Enstrom macrogobulinaemia is a disorder designated with a nomenclature of a Swedish physician Jan Gosta Waldenstrom (1906-1996). The exceptional disease was initially scripted in 1944 [1,2]. Waldenstrom macroglobulinaemia may be defined as the appearance of a serum para-protein such as immunoglobulin M (Ig M) in addition to a malignant lymphoplasmacytic infiltrate confined to the bone marrow. Lymphoplasmacytic Lymphoma (LPL) may be cogitated as a neoplasm comprising of miniature B lymphocytes, plasmacytoid lymphocytes and mature plasma cells. The tumefaction generally implicates the bone marrow with an occasional presence in the lymph node and spleen. Lymphoplasmacytic lymphoma is accompanied by Waldenstrom macroglobulinaemia in a majority (95%) of instances [1,2]. The dual conditions may be denominated by an immunoglobulin M (Ig M) monoclonal gammopathy accompanied by an emergence of a lymphoplasmacytoid lymphoma restricted to the bone marrow. Lymphoplasmacytoid lymphoma may concur with an infection of hepatitis C virus (HCV). A familial prevalence may be delineated. An estimated 1.4% of neoplasm of miniature B lymphocytes may be cogitated by lymphoplasmacytoid lymphoma [1,2].
Wald Enstrom巨球蛋白血症是一种由瑞典医生Jan Gosta Waldenstrom(1906-1996)命名的疾病。这种特殊疾病最初是在1944年被记录下来的[1,2]。Waldenstrom巨球蛋白血症可以定义为除了局限于骨髓的恶性淋巴浆细胞浸润外,还出现血清副蛋白,如免疫球蛋白M (Ig M)。淋巴浆细胞性淋巴瘤(LPL)可以理解为一种由微型B淋巴细胞、浆细胞样淋巴细胞和成熟浆细胞组成的肿瘤。肿大通常累及骨髓,偶尔出现于淋巴结和脾脏。淋巴浆细胞性淋巴瘤在大多数(95%)病例中伴有华登斯特罗姆大球蛋白血症[1,2]。这两种情况可能以免疫球蛋白M (Ig M)单克隆伽玛病为特征,并伴有局限于骨髓的淋巴浆细胞样淋巴瘤的出现。淋巴浆细胞样淋巴瘤可并发丙型肝炎病毒(HCV)感染。可以描述家族性流行。估计有1.4%的微型B淋巴细胞肿瘤可能由淋巴浆细胞样淋巴瘤引起[1,2]。

The nasopharynx is a commonly involved site of the lymphoma. Cases of it have been reported from countries as far apart as China [1-4], Hong Kong [5], India [6,7], Korea [8], Morocco [9], Tunisia [10], and USA [11]. Therefore, this paper deals with the Nigerian cases with special reference to the Ibo ethnic group [12]. This study was facilitated by the establishment of a Regional Pathology Laboratory such as the one canvassed by a Birmingham (UK) group as being of immense use in epidemiological analysis [13]. Investigation
鼻咽部是淋巴瘤的常见受累部位。报告病例的国家相距遥远,如中国[1-4]、香港[bb2]、印度[6,7]、韩国[bb4]、摩洛哥[bb3]、突尼斯[bb0]和美国[bb1]。因此,本文对尼日利亚的案例进行了研究,并特别参考了伊博族[12]。这项研究是由区域病理学实验室的建立促进的,例如伯明翰(英国)的一个小组在流行病学分析中发挥了巨大的作用。调查

Recent Trends and Strategies for Targeting M – Cells via Oral Vaccine against Hepatitis B: A Review 乙型肝炎口服疫苗靶向M细胞的最新趋势和策略:综述
Pub Date : 2019-02-06 DOI: 10.19080/IJCSMB.2019.05.555671

Background: The presence of a mucus layer that covers the surface of a variety of organs has been capitalized to develop mucoadhesive dosage forms that remain in the administration site for more prolonged times, increasing the local and systemic bioavailability of the administered vaccine. The emergence of micro and nanotechnologies together with the implementation of non‐invasive and painless administration routes has revolutionized the pharmaceutical market and the treatment of disease. Objectives: To overcome the main drawbacks of the various routes and to maintain patient compliance high, the engineering of innovative drug delivery systems administrable by mucosal routes has come to light and gained the interest of the scientific community due to the possibility to dramatically change the drug pharmacokinetics. Method: We review herein reported observations on nanoparticle (NP) mediated immunostimulation and immunosuppression, focusing on possible theories regarding how manipulation of particle physicochemical properties can influence their interaction with immune cells to attain desirable immunomodulation and avoid undesirable immunotoxicity. Result: These results show that both HBV particles and purified HBsAg have an immune modulatory capacity and may directly contribute to the dysfunction of mDC in patients with chronic HBV. The direct immune regulatory effect of HBV and circulating HBsAg particles on the function of DC can be considered as part of the mechanism by which HBV escapes immunity. Conclusion: NPs are recognized as self or there is an absence of immune recognition, this represents a major area of interest in the field of drug delivery. It is now well accepted due to their huge advantages and properties such as NP size, surface charge, hydrophobicity/hydrophilicity and the steric effects of particle coating can dictate NP compatibility with the immune system.
背景:覆盖各种器官表面的粘液层的存在已被利用来开发在给药部位停留更长时间的粘膜粘合剂剂型,从而提高给药疫苗的局部和全身生物利用度。微型和纳米技术的出现,以及无创和无痛给药途径的实施,彻底改变了药物市场和疾病治疗。目的:为了克服各种途径的主要缺点,并保持患者的高依从性,通过粘膜途径管理的创新药物递送系统的工程已经曝光,并由于有可能显著改变药物药代动力学而引起了科学界的兴趣。方法:我们回顾了本文报道的关于纳米粒子(NP)介导的免疫刺激和免疫抑制的观察结果,重点关注关于操纵粒子物理化学性质如何影响其与免疫细胞的相互作用以获得理想的免疫调节并避免不期望的免疫毒性的可能理论。结果:HBV颗粒和纯化的HBsAg均具有免疫调节能力,可能直接导致慢性HBV患者mDC功能障碍。HBV和循环HBsAg颗粒对DC功能的直接免疫调节作用可以被认为是HBV逃避免疫机制的一部分。结论:NP被识别为自身或缺乏免疫识别,这是药物递送领域的一个主要兴趣领域。由于其巨大的优势和性质,如NP尺寸、表面电荷、疏水性/亲水性,以及颗粒涂层的空间效应,可以决定NP与免疫系统的兼容性,因此它现在被广泛接受。
