To improve the visual appearance of object regions in medical images, image enhancement techniques are used as potential pre-processing techniques. Due to its simplicity and easiness of implementation, histogram equalization is widely preferred in many applications. But due to its mapping function based image transformation during enhancement process affect the biomedical patterns which are essential for diagnosis. To mitigate these issues in medical images, a new method based on gradient computations and Texture Driven based Dynamic histogram equalization (GTDDHE) is accomplished to increase the visual perception. The spatial texture pattern is also included to ensure the texture retention and associated control over its variations during histogram modifications. Experimental results on MRI, CT images, eyes images from medical image datasets and quantitative analysis by PSNR, structural similarity index measurement (SSIM), information entropy (IE) and validated that the proposed method offers improved quality with maximum retention of biomedical patterns across all types of medical images.","PeriodicalId":53488,"journal":{"name":"International Journal of Biology and Biomedical Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41892641","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}

This study investigates the information source usage, knowledge, attitude and practices of 200 dwellers of Lagos, Nigeria towards HIV/HBV co-infection. In this cross-sectional study, the simple random sampling method was employed in selecting 200 participants in the most populated local government in Lagos state, Nigeria. Questionnaire instrument was created, to elicit responses on four major areas: uses of information sources, knowledge, attitude, health practice towards HIV/HBV co-infection. Descriptive statistical data in percentages and cross-tabulations were employed. The study indicated that 60.4% of the respondents source for information on HIV/HBV co-infection on television. Furthermore, while 60% noted the co-infection is caused by a virus 48.5% declared that the fear of death will be their main concern if they were diagnosed with the co-infection. The result further reveals that only 26.8% of the sampled respondents have been tested for the co-infection in Lagos State. The study concludes that there is need for the creation of preventive information campaigns for awareness in order to mitigate the rising cases of HIV/HBV co-infection as well as influence persons towards healthy practices. The insight from this study would further provide a focal point of direction to government as well as non-governmental organisations working on HIV/HBV co-infection in Nigeria.","PeriodicalId":53488,"journal":{"name":"International Journal of Biology and Biomedical Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47600441","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}

This way can minimize the patient’s time exposure to X-rays. However, its implementation is very costly in computation time, which constitutes a handicap problem in practice. For this reason, the use of acceleration methods on GPU becomes a real solution. For the acceleration of the FDK algorithm, we have used the GPU on heterogeneous platforms. To take full advantage of the GPU, we have chosen useful features of the GPUs and, we have launched the acceleration of the reconstruction according to some technical criteria, namely the work-groups and the work-items. We have found that the number of parallel cores, as well as the memory bandwidth, have no effect on runtimes speedup without being rough in the choice of the number of work-items, which represents a real challenge to master in order to be able to divide them efficiently into work-groups according to the device specifications considered as principal difficulties if we do not study technically the GPU as a hardware device. After an optimized implementation using kernels launched optimally on GPU, we have deduced that the high capacities of the devices must be chosen with a rough optimization of the work-items which are divided into several work-groups according to the hardware limitations.","PeriodicalId":53488,"journal":{"name":"International Journal of Biology and Biomedical Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41350344","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}

Here, using agrobacteria, a leaf disc transformation of Nicotiana tabacum v. Samsun NN was carried out by transgenes AtDREB2A-FL and AtDREB2A-CA coding the proteins with His-tag on the С-end. The effects of combinations of constitutive 35S CaMV promoter or inducible rd29A promoter with different viral or artificial 5’-untranslated regions (UTR), 5’TMV, 5’PVY, 5’AMV or 5’ARC1, known as translational enhancers were evaluated on the both transgenes’ expression. Using an antibody to His-tag, recombinant protein synthesis was detected in transgenic plants in normal and heat shock conditions. After comparative analysis, it was shown that the properties of different 5’-UTRs vary greatly and depended on separate conjunction of promoter and transgene. The integration of AtDREB2A CA under control of the rd29A promoter and 5’TMV or 5’AMV in genome effectively improved tolerance of tobacco transgenic plants to 400 mM NaCl and to drought.","PeriodicalId":53488,"journal":{"name":"International Journal of Biology and Biomedical Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45992238","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}

The pandemic is still going strong, with additional viral variations popping up all the time. For the close to future, the international response will have to continue. The molecular tests for SARS-CoV-2 detection may lead to False-negative results due to their genetic similarity with other coronaviruses, as well as their ability to mutate and evolve. Furthermore, the clinical features caused by SARS-CoV-2 seem to be like the symptoms of other viral infections, making identification even harder. We constructed seven hidden Markov models for each coronavirus family (SARS-CoV2, HCoV-OC43, HCoV-229E, HCoV-NL63, HCoV-HKU1, MERS-CoV, and SARS-CoV), using their complete genome to accurate diagnose human infections. Besides, this study characterized and classified the SARS-CoV2 strains according to their different geographical regions. We built six SARS-CoV2 classifiers for each world's continent (Africa, Asia, Europe, North America, South America, and Australia). The dataset used was retrieved from the NCBI virus database. The classification accuracy of these models achieves 100% in differentiating any virus model among others in the Coronavirus family. However, the accuracy of the continent models showed a variable range of accuracies, sensitivity, and specificity due to heterogeneous evolutional paths among strains from 27 countries. South America model was the highest accurate model compared to the other geographical models. This finding has vital implications for the management of COVID-19 and the improvement of vaccines.","PeriodicalId":53488,"journal":{"name":"International Journal of Biology and Biomedical Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49274869","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}

Thirty-three healthy adults participated in the measurement of balance by inducing anisometropia with +0.0D, +2.0D, and +5.0D refractive lenses placed in specially made glasses that removed peripheral vision. COP data was collected via force plate and was evaluated by converting it to COP velocity. An α <0.05 was considered statistically significant. Our results show that, provided it is above a minimum threshold level, the greater the change in dynamic stereoscopic vision, the poorer the balance. And it was found that changes below a minimum threshold level did not affect the balance. These results provide a potential explanation for the complementary compensatory action of sensory information, which could not be explained previously based on the change of balance due to changes in visual information across both eyes. Given these data, it seems clear that vision correction is essential for those affected by dynamic stereoscopic vision formation disorders above a certain level in order to improve balance. On the other hand, dynamic stereoscopic vision formation disorders below a certain level can likely be improved using simple somatosensory treatments. This study will help physical therapists better consider dynamic stereoscopic vision when evaluating and conducting therapies designed to increase balance.","PeriodicalId":53488,"journal":{"name":"International Journal of Biology and Biomedical Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70491168","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}
