Background and purpose: Vibration caused by ventilation systems in buildings is one of the harmful physical factors that can cause harm to residents. Therefore, measuring and controlling vibration is important. Materials and Methods: In the first step of the study, the vibration accelerometer was placed on the base of a fan where the vibrations were sent toward the duct wall. A vibration assessment of the building was conducted in the other steps to compare with guidelines. In the next step, isolation method was used to control vibration. By placing the isolator on the duct wall, the accelerometer was located on the body of the duct wall and the value of vibration was measured in a millimeter per second. All stages of the experiment were performed in the Faculty of Health of Isfahan University of Medical Sciences in 2018. Results: The maximum vibration velocity reduction in the building was related to the frequency of 68 Hz, which reached 33 mm/s after isolation. In addition, the fan vibration at 485 Hz was equal to 2.1 m /s, which decreased to 2 mm /s after isolation. Conclusion: Comparison of vibration after fan isolation with standard showed that this method has been effective in reducing the fan vibration resulting in the vibration to reach below the standard.

Ayurveda is the most ancient medical sciences which deal with the powerful medicines with the use of herbals, minerals and herbo-minerals. Amavatari Rasa is one of the most powerful Ayurvedic formulation which comes under the polyherbal formulations, it contains Eranda moola, Triphala, Shuddha Chitraka, Shuddha Vatsanabha as main ingredients and Gomutra as Bhavana dravya indicated in SarvaVatavikara. as it is a VatsanabhayuktaKashtoushadi and irrespective of other Kashtoushadis its name and its less dose indicates that it is more potent than the other Amavataharakashtoushadhis, assimilation in the body is much faster even though the dose is very less and it can competent with other Amavatahara Rasaushadis. Amavatari Rasa was prepared as per the classical reference as there was no analytical standards available for Amavatari rasa in Ayurvedic pharmacopeia of India to check its quality, in this study an effort has been made to carry out the pharmaceutico Analytical study of Amavatari Rasa. The result obtained will be the reference standards and can also be used for future studies on Amavatari Rasa standardization.

Background: Nephrotoxicity is one of the frequent toxicities observed with cyclophosphamide (CP) use which may involve oxidative stress. Cimetidine is an antihistamine with anti-oxidative stress activity.Aims and Objectives: The study aimed to evaluate the effect of cimetidine on cyclophosphamide-induced kidney damage in albino rats.Materials and Methods: Forty eight adult rats randomised into 8 (A-H) groups of 6 rats per group were experimentally used for this study.Group A (control) was treated with water, while groups B-D were treated with 5, 10 and 20 mg/kg of cimetidine intraperitoneally (ip) daily for 5 days respectively. Group E was treated with150 mg/kgof CP ip on the 5th day. Groups F-H were pretreated with 5, 10 and 20 mg/kg cimetidine ip daily for 5 days and treated with CP ip on the 5th day respectively. Rats were sacrificed serum was extracted from blood and evaluated for renal function markers, while kidneys were harvested and evaluated for oxidative stress markers and histology.Results: There were no significant effects (p>0.05) on the body and kidney weights of CP-treated rats. However, impaired kidney functions in CP-treated rats were marked by significant (p<0.05) increases in creatinine, urea, uric acid, sodium, potassium, chloride, bicarbonate, and malondialdehyde levels when compared to control. On the other hand, significant (p<0.05) decreases in superoxide dismutase, catalase, glutathione, glutathione peroxidase, total protein and albumin were obtained in CP-treated rats when compared to control. Necrotic changes were observed in the kidneys of CP-treated rats. However, CP-induced nephrotoxic effects were significantly (p<0.05; 0.01) reversed in cimetidine pretreated rats.Conclusion: Cimetidine shows potential as adjunct remedy for cyclophosphamide associated nephrotoxicity.Asian Journal of Medical Sciences Vol.9(6) 2018 25-30

Woman's Body

The aims of this paper is to explain the use of high heels as an agency for a woman's body. Agency context refers to pain in the body but pain is perceived as something positive. In this paper, the method used is a literature review by reviewing writings related to the use of high heels. The findings in this paper that women experience body image disturbance or anxiety because they feel themselves are not beautiful or not attractive. The use of high heels, makes women more attractive and more confident, on the other hand the use of high heels actually makes women feel pain and discomfort. However, for the achievement of beauty standards, women voluntarily allow their bodies to experience pain. However, the agency's willingness to beauty standards here is meaningless without filtering and directly accepted. Instead women keep negotiating with themselves so as to make a decision why use high heels.

Background: In practice it was difficult or impossible to have a correct diagnosis for the lymphoid proliferation lesions based on only H.E standard histopathology. In addition to histopathology, the application of immunohistochemistry was indispensable for the definitive diagnosis of the malignant or benign tumours and the origin of the tumour cells as well. Objectives: 1. To describe the gross and microscopic features of the suspected lesions of lymphoma; 2. To asses the expression of some immunologic markers for the diagnosis and classification of the suspected lesions of lymphoma. Materials and Method: Cross-sectional research on 81 patients diagnosed by histopathology as lymphomas or suspected lesions of lymphoma, following with immunohistopathology staining of 6 main markers including LCA, CD3, CD20, Bcl2, CD30 and AE1/3. Results: The most site was lymph node 58.1% which appeared at cervical region 72.3%, then the stomach 14.9% and small intestine 12.4%. The other sites in the body were met with lower frequency. Histopathologically, the most type of the lesions was atypical hyperplasia of the lymphoid tissue suspecting the lymphomas 49.4%, lymphomas 34.5%, the other diagnoses were lower including inflammation, poor differentiation carcinoam not excluding the lymphomas, lymphomas differentiating with poor differentiation carcinomas. Immunohistochemistry showed that, LCA, CD3, CD20, Bcl2, CD30 and AE1/3 were all positive depending on such type of tumours. The real lymphomas were 48/81 cases (59.3%), benign ones 35.8% and poor differentiated carcinomas 4.9%. Conclusion: Immunohistochemistry with 6 markers could help to diagnose correctly as benign or malignant lesions, classify and determine the origin of the tumour cells as lymphocytes or epithelial cells diagnosed by histopathology as lymphomas or suspected lesions of lymphomas. Key words: histopathology, immunohistochemistry, lymphomas, poor differentiated carcinomas, hyperplasia, atypicality

Insight Into

The future of medicine belongs to immunology and alergology. I tried to not be too wide in description, but on the other hand to mention the most important concepts of alergology to make access to these diseases more understandable, logical and more useful for our patients, that without complex pathophysiology and mechanism of immune reaction,we gain some basic insight into immunological principles. The name allergy to medicine was introduced by Pirquet in 1906, and is of Greek origin (allos-other + ergon-act; different reaction), essentially representing the reaction of an organism to a substance that has already been in contact with it, and manifested as a specific response thatmanifests as either a heightened reaction, a hypersensitivity, or as a reduced reaction immunity. Synonyms for hypersensitivity are: altered reactivity, reaction, hypersensitivity. The word sensitization comes from the Latin (sensibilitas, atis, f.), which means sensibility,sensitivity, and has retained that meaning in medical vocabulary, while in immunology and allergology this term implies the creation of hypersensitivity to an antigen. Antigen comes from the Greek words, anti-anti + genos-genus, the opposite, anti-substance substance that causes the body to produce antibodies.

This chapter discusses Hilary’s dichotomous body–soul anthropology. Although past scholars have tried to categorize Hilary as ‘Platonic’ or ‘Stoic’, these categories do not fully summarize fourth-century thought, not least because two-way as well as three-way expressions of the human person are also found in Scripture. The influence of Origen is demonstrated with particular reference to the commentary on Ps. 118.73, informed by parallels in Ambrose and the Palestinian Catena. As a result, it is possible to ascribe differences between Hilary’s commentaries to the fact that one is more reliant on Origen than the other. Nevertheless, Hilary’s position always seems to be that the body and soul should be at harmony until the body takes on the spiritual nature of the soul.

The Relationship

The respiratory rates of three species of planktonic copepods, Acartia clausi, Centropages hamatus and Temora longicornis, were measured at four different temperatures.The relationship between respiratory rate and temperature was found to be similar to that previously found for Calanus, although the slope of the curves differed in the different species.The observations on Centropages at 13 and 170 C. can be divided into two groups and it is suggested that the differences are due to the use of copepods from two different generations.The relationship between the respiratory rates and lengths of Acartia and Centropages agreed very well with that previously found for other species. That for Temora was rather different: the difference is probably due to the distinct difference in the shape of the body of Temora from those of the other species.The application of these measurements to estimates of the food requirements of the copepods is discussed.

The One

This paper will focus on one element of the pushback against the massive influx of immigrants taken in for humanitarian purposes, namely, an identity-based chauvinism which uses identity as the point of resistance to the perceived dilution of that identity, brought about by the transformation of culture induced by the incorporation of a foreign other. The solution to this perceived dilution is a simultaneous defence of that culture and a demand for a conformity to it. While those in the critical tradition have encouraged a counter-position of revolutionary transformation by the other through ethics, dialogue, or the multitude, such a transformation is arguably impeded by what is ultimately a repetition of the metaphysics of conformity. Drawing on the personalism of Emmanuel Mounier and the Eucharistic theology of Creston Davis and Aaron Riches, this paper submits an alternative identity politics position that completes the revolutionary impulse. Identity here is not the flashpoint of a self-serving conflict, but the launch-point of politics of self-emptying, whose hallmarks include, on the one hand, a never-ending reception of transformation by the other, and on the other hand, an anchoring in the Body of Christ that is at once ever-changing and never-changing.
