Extracorporeal membrane oxygenation (ECMO) is a revolutionary life-saving technology for patients with severe but potentially reversible pulmonary or cardiac failure or for patients in need of a bridge to transplantation. In the Indian scenario, the facility of ECMO is limited to few specialized healthcare centers having the expertise personnel and the equipment for this technology. However, the critically unwell patients with respiratory and/or cardiac failure are managed by all the healthcare facilities throughout the country. This has led to the development of mobile ECMO team which carries necessary equipment for initiation of ECMO at referral center and also retrieval of the patient on ECMO. We present the case of a patient with H1N1 influenza associated severe ARDS who was retrieved via air-medical transport (fixed wing aircraft) on ECMO by the mobile ECMO team of our center. In the present case, the patient was cannulated and ECMO was initiated at the referral hospital. This allowed a safe transfer of this patient with severe refractory hypoxemia to ECMO centre. The long or short-distance inter-hospital transport of critical patients with respiratory and/or cardiac failure is feasible and safer on ECMO as compared to the conventional methods of transport. The mobile ECMO teams have made this technology available to all even when the admitting hospital doesn’t have this facility and expertise. To the author’s knowledge, this is the first case reported in India of air-medical retrieval of a patient on ECMO. Key-wordsAcute respiratory distress syndrome (ARDS), Air ambulance, Extra corporeal membrane oxygenation (ECMO), H1N1 influenza (Swine flu), Hypoxia, Inter hospital transport INTRODUCTION Extra Corporeal Membrane Oxygenation (ECMO) has seen a remarkable recognition and evolution in its use in the last decade. ECMO has emerged as an invaluable tool in the hands of intensive care physicians in the management of patients with severe pulmonary and/or cardiac dysfunction refractory to conventional management [1] , especially in patients with severe acute respiratory distress syndrome (ARDS).

Microbial composting play an important role in the recycling of different processing wastes and the compost generated by bio-conversion of wastes offers several benefits such as enhanced soil fertility and soil health that can lead to increased agricultural productivity, improved soil biodiversity, reduced ecological risks and a healthier environment. The present experiment was conducted in Plastic pots, which were filled with the different wastes, namely Sugarcane waste, Plants waste, Flower waste, Mausmi waste and Mixed waste, which was inoculated by Yash Activator Plus (2% w/w) with a set control pot of each. The results of this study revealed that with Yash Activator Plus, the temperature was increased rapidly at 20 days of composting which were 50, 52, 58, 54 and 54 ̊C. Control treatments increased temperature up to 45, 44, 48, 46, and 46 ̊C respectively. The total loss of dry matter content at the end of composting amounted to be 37.73, 39.67, 52.94, 51.25 and 40% from the initial amount of Sugarcane waste, Plants waste, Flower waste, Mausmi waste and Mixed waste respectively. The maximum and minimum dry matter contents were decreased in flower waste and sugarcane waste respectively. Increased temperature enhanced the process of composting rapidly due to the thermophilic microorganisms, which reduces the time of composting. On the basis of this study, we can conclude that the mixed consortia of mesophilic and thermophilic microorganisms increased the process of composting, which reduces the time of degradation of different wastes. Key-wordsCompost, Microbial composting, Different waste, Yash Activator Plus INTRODUCTION "Yash Activator Plus" is a very effective microbial consortium for rapid composting. It is a mixture of culture of mesophilic and thermophilic microorganisms specifically for accelerating the composting of organic waste. It contains cultures of Bacteria and fungi along with enzymes, which facilitate bio conversion of organic waste into a stabilized end product called “compost. Use of this microbial consortium for rapid composting: The microbiology of composting is very complex. It involves consortium of fungi and bacteria Actinomyces for bio conversion of organic waste into end product for various uses. Microbial growth in composting depends upon so many factors. Carbon and nitrogen sources are the most critical in terms of bio-degradability of the waste/ biomass. Microbial composting refers to microbiological process which converts waste materials into organic manure, which are rich in plant nutrients and humus [1] .

BackgroundOral health is a multi-factorial concept, determined by knowledge, behavior, and attitude of a person. Like any behavior carried out daily like a habit, oral health behaviors are also repeated like a habit. The multidimensionality of behavioral change makes studying it, and factors associated with it, a challenge, since there are so many aspects to consider. ObjectivesTo find an association between the oral health status and socio-behavioral factors among 12-15 years old school children of Belagavi city, India. MethodsA descriptive cross-sectional study was conducted to find an association between the oral health status and the knowledge, attitude and behavior of adolescents. One thousand participants were selected using two-stage random sampling. Dental caries, bleeding on probing, dental trauma, enamel fluorosis, intervention urgency was recorded according to the WHO 2013 proforma and the parameters regarding knowledge, attitudes as well as behavior using a closed ended self-designed questionnaire. Mann-Whitney U test, Kruskal Wallis, and linear correlation tests were done. ResultsAmong 1000 subjects, 767 (76.7%) participants were found to have dental caries and 512 (51.2%) showed the presence of gingival bleeding. Out of a total score of 41, the mean knowledge score was 34.47 (±3.84) for boys and 34.76 (±4.13) for girls. Linear correlation showed that attitude was weakly correlated (r=0.18 and 0.20 respectively) but with a strong statistical significance to knowledge as well as behavior respectively. ConclusionAttitude when compared separately either with knowledge or behavior showed a weak correlation that was highly significant. Comparison of behavior with caries experience showed a weak negative correlation which was statistically insignificant. Key-wordsOral health, Adolescents, Socio-behavioral, Knowledge, Attitude, Behavior INTRODUCTION The prevalence of non-communicable diseases is significant worldwide; they represent a comprehensive burden to people and society, display large disparities across countries, disproportionately affect poor and disadvantaged population groups and they are increasing rapidly across the globe.

This research presented a chemical study of essential oil from Aniba duckei Kostermans, known as rosewood, as well as its test against bacteria Aeromonas hydrophila, Bacillus cereus, Serratia sp., and Vibrio alginolyticus. For control, we used pipemidic acid, ampicillin, cephalothin, cefoxitin, chloramphenicol, erythromycin, gentamicin, oxacillin, tetracycline, and vancomycin antibiotics. Oil yield was 1.2% (m/m) with linalool being its major component, with 89.34%. The essential oil was more efficient than all antibiotics tested against A. hydrophila and Vibrio alginolyticus. Linalool was less efficient than the A. duckei Kosterman’s essential oil but more effective than many antibiotics. The essential oil, when tested against Bacillus cereus, was second only to gentamicin, while linalool presented less effectiveness than both gentamicin and tetracycline against the same bacteria. But both oil and linalool were effective against Serratia. The A. duckei Kosterman’s essential oil activity was better than linalool’s in all cases due to the oil’s minor components action and synergy between them, which hinder resistance developed by bacteria.

Background: Schizophrenia is a common psychotic disorder, with a risk of about 1%, the etiology of schizophrenia unknown, one of which includes immunological disorders. Although, there are conflicting results, most studies focusing on plasma levels or the production of mitogen-stimulated cytokines. Furthermore, this study compared serum levels of TNF-α in male chronic schizophrenic patients and healthy control. Methods: This cross-sectional study was conducted on 40 male patients diagnosed with chronic schizophrenic and 40 healthy control. Severity of illness was assessed with PANSS. Serum levels of TNF-α were measured by Quantikine HS Human TNF-α Immunoassay. Results: TNF-α levels were significantly higher in chronic schizophrenic (25.12±1.76) to healthy control subjects (5.49±1.69), p=0.001; p<0.05. Conclusion: This study suggested that TNF-α play a role in the immunopathogenesis of schizophrenia and behavioral changes. The relationship between schizophrenia and inflammation was supported by the production of abnormal cytokines. Key-wordsBatak male, Chronic schizophrenic, Healthy control, Serum TNF-α INTRODUCTION Schizophrenia is a common psychotic disorder, with a risk of about 1%, the most common early onset of this disease is 15-30 years of age, and is a chronic disease that causes disruption to patients and their families. [1] The exact cause of schizophrenia is not known, although several etiological theories have been proposed for the disease, including developmental or neurodegenerative processes, neurotransmitter abnormalities, viral infection and immune dysfunction or autoimmune mechanisms.

The tobacco plant Nicotiana has probably been responsible for more deaths than any other herb as it is market driven commodity of economic benefit. While the majority will likely be killed by use of cigarettes, tobacco use in other forms also contributes to worldwide morbidity and mortality. Chewing leaf tobacco is less used now as the ban is imposed on it. We tested the genotoxic potential of chewing leaf tobacco using in vivo cytogenetic testsperipheral blood micronucleus test, and sperm abnormality assay. Three doses of tobacco viz., 3%, 5%, and 10% were given for 14 days. Cyclophosphamide, an indirect acting clastogen was used as positive control agent and it was injected intra peritoneally to the animals only once. Double distilled water was used as negative control. The frequency of micronucleated normochromatic erythrocytes (MNNCE) was increased in tobacco treated mice with the maximum MN being induced in NCEs at 10% dose. All three tobacco doses used in this study, induced significant abnormal sperms compared to controls (P<0.05). The chewing leaf tobacco at a certain concentration is genotoxic. Key-wordsChewing Leaf tobacco, Peripheral blood micronucleus, Swiss albino mice, Howell-Jolly bodies INTRODUCTION The tobacco plant has conquered the world as a powerful drug in the form of cigarettes, cigars, and pipes [1,2] Nicotiana varieties originate mainly from South America. The tobacco plant, Nicotiana, has probably been responsible for more deaths than any other herb. At present, tobacco smoking is causing over 3 million deaths a year worldwide, and if current smoking trends continue the annual mortality will exceed 10 million by around 2030. Undoubtedly, tobacco is the most important avoidable cause of premature death and disease in the world . Smokeless tobacco is consumed without burning the product and can be used orally and through nasal route. Oral smokeless tobacco products are placed in the mouth, cheek or lip and sucked (dipped) or chewed. In India, smokeless tobacco is famous in the form of Gudakhu, Mishri, snuff, chewing tobacco, Masher, Mawa, Sadagura etc. Maybe tobacco is the only one plant now known the world over for the overall health burden it causes to public health.

烟草植物烟草造成的死亡人数可能比任何其他草药都要多,因为它是市场驱动的经济利益商品。虽然大多数人可能会因吸烟而死亡,但其他形式的烟草使用也会导致世界范围内的发病率和死亡率。由于禁令的实施,嚼叶烟草的使用量减少了。采用体内细胞遗传学试验、外周血微核试验和精子异常试验对咀嚼烟叶的遗传毒性进行了研究。烟草分别为3%、5%和10%,连续服用14天。采用间接作用破乳剂环磷酰胺作为阳性对照剂,只腹腔注射一次。以二次蒸馏水为阴性对照。烟草处理小鼠微核正染红细胞(MNNCE)出现频率增加,10%剂量的烟草处理小鼠微核正染红细胞(MNNCE)达到最大。与对照组相比,本研究中使用的所有三种烟草剂量均诱发了显著的精子异常(P<0.05)。一定浓度的咀嚼烟叶具有遗传毒性。烟草植物作为一种强大的药物,以香烟、雪茄和烟斗的形式征服了世界[1,2]。烟草品种主要产于南美洲。烟草植物Nicotiana可能是造成死亡人数最多的植物。目前,吸烟在全世界每年造成300多万人死亡,如果目前的吸烟趋势继续下去,到2030年左右,每年死亡人数将超过1000万人。毫无疑问,烟草是世界上导致过早死亡和疾病的最重要的可避免原因。无烟烟草是在不燃烧产品的情况下消耗的,可口服或经鼻途径使用。将口服无烟烟草制品放在口腔、脸颊或嘴唇上,吸(蘸)或咀嚼。在印度,无烟烟草以Gudakhu、Mishri、鼻烟、嚼烟、Masher、Mawa、Sadagura等形式而闻名。也许烟草是目前世界上唯一一种因其对公众健康造成整体健康负担而为人所知的植物。这可能是唯一一种被几乎所有生命科学期刊至少引用过一次的植物。在线阅读本文快速响应代码网站:

Human immunodeficiency virus (HIV) is a major contributor to the global burden of the disease, opportunistic infections, and tumors follow. HIV also directly attacks the immune system and affects certain body’s system (like Central Nervous System, Respiratory and Cardiovascular Systems, Digestive System etc). HIV transmission is complex and depends on the number of behavioral and biological co-factors. The hallmark of HIV infection is the progressive depletion of CD4 helper T cells because of reduced production and increased destruction. Although the typical HIV infected patient shows a sustained CD4 cell increase, a remarkable number of subjects never achieve normal ranges of CD4. HIV infection is also characterized by a marked increase in immune activation, which includes both the adaptive and innate immune systems and abnormalities in coagulation. Extraordinary efforts in the fields of clinical, pharmacology, and biology care have contributed to progressively turn HIV infection from an unavoidably fatal condition into a chronic manageable disease, at least in the countries where HIV infected people have full access to the potent anti-retroviral (ARV) drug combinations that permit a marked and sustained control of viral replication. Although their pathogenesis is still under-discussed, they are likely to originate from immune dysfunction associated with HIV infection and chronic inflammation. The last consideration regards the dis-homogenous pattern of HIV disease worldwide. Key-wordsHuman immunodeficiency virus (HIV), simian immunodeficiency viruses (SIV), Antiretroviral (ARV) therapy, Acquired immunodeficiency syndrome (AIDS), Cell mediated immunity (CMI), Anti-retroviral agents INTRODUCTION HIV virus is the harmful mediator of Acquired Immunodeficiency Syndrome (AIDS), was identified in 1983 following the first reported cases of AIDS in 1981-1982. HIV is a member of a class known as Retroviruses. These viruses store their genetic information as ribonucleic acid (RNA), unlike most viruses which store their genetic information as deoxyribonucleic acid (DNA). Previous to viral replication can obtain place, the RNA must be converted to DNA by the reverse transcription enzyme, hence the Latin term Retro, meaning 'turning back' . HIV comprises an outer envelope consisting of a lipid bilayer with spikes of glycoproteins (gp), gp41 and gp120 encoded by env gene. These glycoproteins (gp) are associated in such a manner that glycoproteins 120 protrude from the surface of the HIV virus. The envelope is inside membrane made of nucleocapsid (p 17, matrix protein), which surrounds a central core of protein, p24 (capsid protein) encoded by gag gene.

人类免疫缺陷病毒(HIV)是全球疾病负担的主要贡献者,机会性感染和肿瘤随之而来。HIV也直接攻击免疫系统,影响身体的某些系统(如中枢神经系统、呼吸和心血管系统、消化系统等)。艾滋病毒传播是复杂的,取决于行为和生物辅助因素的数量。HIV感染的标志是CD4辅助性T细胞的逐渐消耗,因为CD4辅助性T细胞的产生减少,破坏增加。虽然典型的HIV感染患者CD4细胞持续增加,但相当多的受试者从未达到正常范围的CD4。HIV感染的另一个特征是免疫激活显著增加,包括适应性和先天免疫系统以及凝血功能异常。在临床、药理学和生物学护理领域作出了非凡的努力,使艾滋病毒感染逐渐从一种不可避免的致命疾病转变为一种可控制的慢性疾病,至少在艾滋病毒感染者能够充分获得强效抗逆转录病毒药物组合的国家是这样,这些药物组合可以显著和持续地控制病毒复制。尽管其发病机制尚不清楚,但它们可能源于与HIV感染和慢性炎症相关的免疫功能障碍。最后一个考虑是关于全世界艾滋病毒疾病的不均匀模式。人类免疫缺陷病毒(HIV)、猿猴免疫缺陷病毒(SIV)、抗逆转录病毒(ARV)治疗、获得性免疫缺陷综合征(AIDS)、细胞介导免疫(CMI)、抗逆转录病毒药物简介HIV病毒是获得性免疫缺陷综合征(AIDS)的有害媒介,在1981-1982年首次报道艾滋病病例后,于1983年被发现。HIV是逆转录病毒中的一员。这些病毒以核糖核酸(RNA)的形式储存它们的遗传信息,不像大多数病毒以脱氧核糖核酸(DNA)的形式储存它们的遗传信息。在病毒复制能够获得位置之前,RNA必须通过逆转录酶转化为DNA,因此拉丁语术语Retro,意为“回头”。HIV包括一个由脂质双分子层组成的外包膜,由env基因编码的糖蛋白(gp)、gp41和gp120尖峰组成。这些糖蛋白(gp)以这样一种方式相关联,糖蛋白120从HIV病毒表面突出。包膜是由核衣壳(p17,基质蛋白)组成的膜内,核衣壳包裹着一个由gag基因编码的核心蛋白p24(衣壳蛋白)。在线阅读本文快速响应代码网站:

Globally tuberculosis remains a challenge from the point of diagnosis, detection of drug resistance, and treatment. Treatment can only be initiated, when infection is detected and it’s based on the results of AST, recently there has been a marked increase in the development and testing of novel assays designed to detect Mycobacterium tuberculosis. Although most important advances that would develop tuberculosis (TB) analysis have not been realized, we are beginning to see the innovations that have been prompted by the recognition of the economic potential of the market for new diagnostic tests for TB and considerably increased public and private funding and awareness. In this present review, we focused on the newer tests that are accessible for the analysis of suppressed and active tuberculosis and rapid detection of drug resistance, nucleic acid amplification for identification of M. tuberculosis complex, and rapid tests for detecting drug resistance. PCR-based technologies and hybridization assays used for the recognition of the mycobacteria. Though these newer techniques are useful for a rapid result, emphasizing that culture-based diagnosis is still the ‘gold standard’ for the diagnosis and follows up on tuberculosis. Key-wordsDrug Sensitivity Testing (DST), M. tuberculosis, Molecular diagnosis, Tuberculosis infection, PCR, INTRODUCTION Tuberculosis (TB) is one of the leading infectious diseases in the world and is responsible for more than 2 million deaths and 8 million new cases annually [1] and in India, accounts for one-fifth of this global burden of TB . The disease is caused by a bacterium called M. tuberculosis. The bacteria usually attack the lungs, but can infect any part of the body such as the kidney, intestine, pleura, spine, and brain. If not treated properly, this infectious disease can be fatal . TB and HIV have been closely linked since the emergence of AIDS and both diseases is a major public health challenge. It is estimated that 60-70% of HIV positive persons will develop tuberculosis in their lifetime . Smear microscopy has suboptimal sensitivity and detects only about 60-70% of the TB cases. The implementation of culture for the diagnosis can improve the TB detection rate of a laboratory by about 30-40%. These two laboratory methods, smear microscopy and culture are still the “gold standards” for the diagnosis of TB and culture is considered as the most sensitive method.

从诊断、发现耐药性和治疗的角度来看,全球结核病仍然是一个挑战。只有在检测到感染时才能开始治疗,治疗是基于AST的结果,最近,用于检测结核分枝杆菌的新型检测方法的开发和测试有了显著的增加。虽然发展结核病分析的最重要进展尚未实现,但由于认识到结核病新诊断检测市场的经济潜力,以及公共和私人供资和认识的大幅增加,我们开始看到推动创新的出现。在这篇综述中,我们重点介绍了用于抑制和活动性结核病分析和快速检测耐药性的最新检测方法,用于鉴定结核分枝杆菌复合体的核酸扩增方法,以及用于检测耐药性的快速检测方法。基于pcr的技术和杂交分析用于分枝杆菌的识别。虽然这些较新的技术有助于快速取得结果,但强调基于培养的诊断仍然是结核病诊断和随访的“金标准”。结核病(TB)是世界上主要的传染病之一,每年造成200多万人死亡,800万新发病例[1],在印度,结核病占全球结核病负担的五分之一。这种疾病是由一种叫做结核分枝杆菌的细菌引起的。这种细菌通常攻击肺部,但也可以感染身体的任何部位,如肾脏、肠道、胸膜、脊柱和大脑。如果治疗不当,这种传染病可能是致命的。自艾滋病出现以来,结核病和艾滋病毒一直密切相关,这两种疾病都是一项重大的公共卫生挑战。据估计,60-70%的艾滋病毒阳性者将在其一生中发展为结核病。涂片镜检的灵敏度不够理想,只能检测到约60-70%的结核病病例。实施培养诊断可使实验室的结核病检出率提高约30-40%。涂片镜检和培养这两种实验室方法仍然是诊断结核病的“金标准”,培养被认为是最敏感的方法。在线阅读本文快速响应代码网站:
