This study enrolled 2012 participants: COVID-19 cases (1006 patients), and control group (1006 subjects), 50.9% were Saudis and 49.1% were non-Saudis. Mean age for all participants was 36.0±12.7 years and ranged from 8 to 80 years. Mean age was 38.6+15.3 years for COVID-19+ve cases and 33.4±8.6 years for controls. Mean age significantly differed in COVID-19+ve cases from controls (p<0.001). COVID-19 infection was significant in Saudi participants compared to non-Saudi participants (p<0.001). In COVID-19 group, the frequencies of blood groups O, A, B and AB were 44.5%, 31.3%, 19.7% and 4.5%, respectively. The percentage of COVID-19 infection was higher in subjects having blood groups O and A. Regarding Rh factor, 94.0% of all participants were Rh+ve and 6.0% were Rh-ve. Among COVID+ve cases, 93.4% were Rh positive cases and 6.6% were Rh negative cases, while in the controls, 94.5% were Rh+ve and 5.5% were Rh-ve. The number of COVID-19+ve cases exceeded the number of healthy controls in A+ve subjects but not in O+ve and B+ve subjects. In multivariate analysis, people with blood groups B and AB were less likely to be infected (p =0.049) compared to those with groups O and A. In conclusion, older adults had greater risk of COVID-19 infection. Gatherings culture increased COVID-19 infection. Individuals with blood groups B and AB are less likely to get COVID-19 infection than O and A subjects. Rh+ve in O+ve and A+ve is associated with increased COVID-19 infection.","PeriodicalId":93072,"journal":{"name":"American journal of biomedical science & research","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82731258","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 cytocompatibility of modified surfaces with commercially available α-PLL and electrodeposited ε-PLL was compared by combination of DFT computational simulations with experimental electrochemical and cell adhesion studies to obtain “smart” surface application. Experimental study of fibroblasts adhesion showed better viability of cells on ε-PLL than on α-PLL after modification of Fe surfaces as “smart” surfaces to obtain a different hydrophobicity. The porosity of Fe (110) prevented direct measurements of contact angle and therefore surface hydrophobicity was simulated with calculation of adsorption energies for Fe with both α-/ε-PLL structures. This technique was also employed to calculate the interaction of O-H bonds at the surface. The corrosion potential of Fe (110) with superficially modified ε-PLL was shifted by 0.088V compared to the bare iron surface, thus indicating a stronger resistance to corrosion. The results suggest that modification of Fe surface with ε-PLL has a more pronounced effect on cellular growth on this implant and that the slightly hydrophobic character of ε-PLL leads to better cell adhesion ability.","PeriodicalId":93072,"journal":{"name":"American journal of biomedical science & research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47096374","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}

For modeling, we use a dynamic soliton model that takes into account the chirality conditions in active and passive neural networks. Based on this model, it is supposed to study the state of the network. The term neural networks refers to the networks of neurons in the mammalian brain. Neurons are its main units of computation. In the brain, they are connected together in a network to process data. This can be a very complex task, and so the dynamics of neural networks in the mammalian brain in response to external stimuli can be quite complex. The inputs and outputs of each neuron change as a function of time, in the form of so-called spike chains, but the network itself also changes. We learn and improve our data processing capabilities by establishing reconnections between neurons [1-3]. The training set contains a list of input data sets along with a list of corresponding target values that encode the properties of the input data that the network needs to learn. To solve such associative problems, artificial neural networks can work well, when new data sets are governed by the same principles that gave rise to the training data [4].","PeriodicalId":93072,"journal":{"name":"American journal of biomedical science & research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69883000","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 fact, colorectal cancer (CRC) is the most frequent type of cancer in the world and it is the second most common type of cancer in both genders (women: 10.1%; men: 12.4%) [1]. Several data showed that the number of newly diagnosed CRC cases continues to grow especially in the developing countries [2]. For several years, Tunisia has had a low incidence of CRC that seems very far from developed countries, but significant variation in colorectal cancer incidence rates and trends have been observed in our country, without a consistent screening program. The predicted CRC incidence rate by 2024 should be 39.3/100,000 for males and 22.9/ 100,000 for females [3]. Natural products from plants have been intensively explored to find compounds providing against a large number of diseases associated to cancer. The Mediterranean kitchen is one of the most known, and contains a unique mixture of flavors, tastes and nutrients that have no equal around the world [4]. The Tunisian kitchen is a good example. Actually, the Romans and Carthaginians, and well before them the Greeks, brought a lot of recipes and left for us a huge traditional food heritage. This kitchen is reputed for its proper combination that has never been elaborated. It is characterized by a special use of herbs and aromatic plants [5], and Curcuma is one of these spices. It is widely Abstract Background: Curcuma longa is widely used for its ability to inhibit carcinogenesis and the capacity to exert a chemo-preventive effect in different types of cancers including colorectal cancer. While our food habits have changed, the prevalence of colorectal cancer have not stopped increasing.","PeriodicalId":93072,"journal":{"name":"American journal of biomedical science & research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49271006","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}
