It is also used to save lives in critical care and emergency situations. Although there were distant precursors to telemedicine, it is essentially a product of 20th century telecommunication and information technologies. These technologies permit communications between patient and medical staff with both convenience and fidelity, as well as the transmission of medical, imaging and health informatics data from one site to another. Early forms of telemedicine achieved with telephone and radio have been supplemented with video telephony, advanced diagnostic methods supported by distributed client/server applications and additionally with telemedical devices to support in-home care. There is a growing trend in the health domain to incorporate Smartphones and other wireless technologies to provide more efficient, cost effective and higher quality healthcare. With newer more sophisticated mobile devices for example, Smartphones this is an escalating practice. To date the use of mobile phone technology in the healthcare domain (mHealth) has been limited to uses such as disseminating information. However, mHealth is beginning to include software and data applications based on mobile devices and technologies. This movement is largely due to the advent of newer technologies associated with Smartphones. Some Smartphones can now be considered to be intelligent sensors with sensing capabilities such as Global Positioning System (GPS) location, proximity and accelerometers. This study examines the use of such technology in providing seamless mobile communications for telemedicine.","PeriodicalId":89887,"journal":{"name":"American medical journal","volume":"5 1","pages":"8-12"},"PeriodicalIF":0.0,"publicationDate":"2014-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3844/AMJSP.2014.8.12","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70192855","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}

Its use has led to very good results, especially in difficult cases where severe bone defect is present, as it is found to have osteoconductive and possibly, osteoinductive properties. So, it is of great inter est to shed light to the mechanisms through which t his material leads to new bone formation after being im planted. For this reason, a review of the current literature was undertook. Porous tantalum is, biolo gically, relatively inert, meaning that its bonding capacity to the bone is restricted. In order to overcome this o bstacle, it undergoes thermal processing in alkalin e environment. This process leads to extensive hydroxyapatite form ation on its surface and thus, to better integratio n of porous tantalum implants. Apart from this, new bone tissue formation occurs inside the pores of porous tantal um after its implantation and this new bone retains the characte ristics of normal bone, i.e., bone remodeling and H aversian systems formation. This finding is enhanced by the observation that porous tantalum is an appropriate substrate for osteoblast adherence, proliferation and differe ntiation. Furthermore, the finding that osteoblasts derived from old women (>60 years old) and cultivated on porous tantalum may grow faster than osteoblasts taken fro m younger women (<45 years old) and cultivated on other substrates, can partially explain porous tantalu m good performance in cases of patients with severe bone d efects. In conclusion, porous tantalum chemical and mechanical properties are those that, probably, def ine the already noticed good performance of this ma terial. However, further research is needed to totally clar ify the mechanisms through which they contribute to that.","PeriodicalId":89887,"journal":{"name":"American medical journal","volume":"5 1","pages":"63-72"},"PeriodicalIF":0.0,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3844/AMJSP.2014.63.72","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70192846","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}

In sharp cont rast, there are many published studies that BPA has a wide range of significant adverse effects including structural and neurochemical changes throughout the brain associated with behavioral changes, such as hyperactivity, learning deficits and increased aggression in both males and females. So the aim of the present study was to investigate effect of BPA on learning and memory in passive avoidance learning model. Thirty six male Sprague Dawley rats weighing 180-260 g were used. The animals were divided into six groups: 1- control group (without any treatment) 2-sham group (received sesame oil the same volume as experimental, n = 6 ); 3-5 experimental (received BPA 5, 50, 100 and 150 mg kg -1 day, n = 24). BPA was administrated by oral intake by gavage for 15 days. Learning and memory were performed by shuttle-box. Data was analyzed by Kruskal-Wallis nonparametric test. The level of sig nificance was considered P<0.05. Our data showed that BPA does not have a significant difference in time spent in light in doses of 5, 50 mg kg -1 day in learning and memory. BPA with dose of 100 and 150 mg kg -1 day showed a significant decrease in time spent in light relative to the control and sham in learning and memory. According to our results, BPA impaired learning and avoidance memory with high doses in the passive avoidance learning task.","PeriodicalId":89887,"journal":{"name":"American medical journal","volume":"4 1","pages":"190-196"},"PeriodicalIF":0.0,"publicationDate":"2013-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3844/AMJSP.2013.190.196","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70192353","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}

Although genetic factors have been associated to this pathological condition, characterization of the sequence patterns in the regulatory sites, for example, in 3’ or 5’ Untranslated Regions (UTR), remains to be explored. In particular, the 5’ UTR of genes associated with the regulation of blood pressure and oxidative stress are analyzed in this article. To gain insight into how certain DNA motifs are involved with high blood pressure, we decided to perform a study with sequences from genes reported as regulators of blood pressure and oxidative stress. 5’ UTR gene sequences were submitted to patterns recognition by the Multiple Em for Motif Elicitation (MEME) software. Afterward, the motifs obtained were searched for in the Transcription Element Search System (TESS) and Consite platforms, in order to identify the submitted sequence as element response of some transcription factor described previously. Three different motifs in each group of vasorelaxing-and vasocontractile-related gene sequences were detected. In the vasorelaxing group, motif lengths were 39 to 50 nucleotides and were located from -361 to -167 bp before the Open Reading Frame (ORF). In turn, motifs in vasocontractile group sequences were located from -619 to -570 nucleotides, with a length of from 18 to 40 nucleotides. Regarding the nucleic acid content in the motifs found, adenine was more prevalent in vasorelaxing-related sequences with 45% of the average frequency, whereas guanine on those vasocontractile-related sequences with 38%. Distinct motif sequences and variations of nucleotide content in the promoter region of vasorelaxing and vasocontractile-activity related genes were detected. These motifs of each group of genes, with a putative antagonistic role between them, might be a differential cis-regulatory elements of transcriptional machinery.","PeriodicalId":89887,"journal":{"name":"American medical journal","volume":"4 1","pages":"184-189"},"PeriodicalIF":0.0,"publicationDate":"2013-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3844/AMJSP.2013.184.189","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70192298","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}
