On (Semi)Topological BCC-algebras

In this paper, we introduce the notion of (semi)topological BCC-algebras and derive here conditions that imply a BCC-algebra to be a (semi)topological BCC-algebra. We prove that for each cardinal number α there is at least a (semi)topological BCC-algebra of order α: Also we study separation axioms on (semi)topological BCC-algebras and show that for any infinite cardinal number α there is a Hausdorff (semi)topological BCC-algebra of order α with nontrivial topology

Effect of Concept Mapping on Approach to Learning Among Nursing Students

Background & Aim: Most of the recent studies in nursing education have been focused on outcomes of learning. Conventional clinical nursing education, which emphasizes on skill acquisitions, may not encourage students to adopt meaningful or deep learning approaches. This study examined the effect of Concept Mapping on learning approaches among nursing students.Methods & Materials: In this quasi-experimental study, 53 nursing students were randomly divided into two control (n=25) and experimental (n=28) groups. We taught concept mapping for the nurses in the experimental group to use it in caring patients and learning clinical skills. The control group received traditional nursing care plan lessons. Before and at the end of the intervention, the students' approach to learning was assessed using the Study Process Questionnaire. Data was analyzed using independent t test.Results: No statistically significant difference was found between the control and experimental groups on demographics, surface and deep approaches to learning at the beginning of the study (P>0.05). Deep approach to learning increased significantly in the experimental group after the intervention (P=0.03). There was also statistically significant difference in the deep approach to learning between two groups (P=0.02). No statistically significant difference was found in the surface approaches to learning between two groups.Conclusion: The results of this study provided empirical support for the use of concept mapping as a meta cognitive intervention to increase students' meaningful learning and academic achievement

Abstract. In last ten years many mathematicians have studied properties of BL-algebras endowed with a topology

Multiplicity results for a non-local problem with concave and convex nonlinearities

We shall prove a multiplicity result for a non-local problem with a super-critical nonlinearity of the form, (−Δ)su=u|u|p−2+μu|u|q−2,inΩ,u=0,onRn∖Ω,where Ω⊂ℝn is a bounded domain, 0<s<1 and 1<q<2<p. As a consequence of our results, for each p>2, there exists μ∗>0 such that for each μ∈(0,μ∗) problem (1) has a sequence of solutions with a negative energy. This result is new for super-critical values of p. We shall also explore the existence of symmetric solutions for symmetric domains. Our methodology is based on a variational principle established by one of the authors that allows one to deal with super-critical problems when the standard Euler–Lagrange functional is restricted to certain convex sets

An overview on tumor treating fields (TTFields) technology as a new potential subsidiary biophysical treatment for COVID-19

COVID-19 pandemic situation has affected millions of people with tens of thousands of deaths worldwide. Despite all efforts for finding drugs or vaccines, the key role for the survival of patients is still related to the immune system. Therefore, improving the efficacy and the functionality of the immune system of COVID-19 patients is very crucial. The potential new, non-invasive, FDA-approved biophysical technology that could be considered in this regard is tumor treating fields (TTFields) based on an alternating electric field has great biological effects. TTFields have significant effects in improving the functionality of dendritic cell, and cytotoxic T-cells, and these cells have a major role in defense against viral infection. Hence, applying TTFields could help COVID-19 patients against infection. Additionally, TTFields can reduce viral genomic replication, by reducing the expressions of some of the vital members of DNA replication complex genes from the minichromosome maintenance family (MCMs). These genes not only are involved in DNA replication but it has also been proven that they have a crucial role in viral replication. Also, TTFields suppress the formation of the network of tunneling nanotubes (TNTs) which is knows as filamentous (F)-actin-rich tubular structures. TNTs have a critical role in promoting the spread of viruses through improving viral entry and acting as a protective agent for viral components from immune cells and even pharmaceuticals. Moreover, TTFields enhance autophagy which leads to apoptosis of virally infected cells. Thus, it can be speculated that using TTFields may prove to be a promising approach as a subsidiary treatment of COVID-19. Graphical abstract: [Figure not available: see fulltext.

Evaluating the efficacy of probiotic on treatment in patients with small intestinal bacterial overgrowth (SIBO) - A pilot study

Background & objectives: Small intestinal bacterial overgrowth (SIBO) leads to several gastrointestinal (GI) problems and complications leading to malabsorption. The effectiveness of probiotics in the treatment of SIBO syndrome has not been well studied. This pilot study was aimed to assess the efficacy of a probiotic consisting of lactobacilli in the treatment of SIBO. Methods: In this study, 30 cases suffering from chronic abdominal pain or diarrhoea and with a positive hydrogen breath test were randomized in a double-blind manner into two groups: probiotic drug user and control group. After an initial 3-week aggressive therapy with broad-spectrum antibiotics, a 15-day maintenance antibiotic therapy with lactol was administered for the study group and the same regimen without lactol for the control group. After six months the HBT result and the GI symptoms were analyzed and compared between the two groups. Results: The result of hydrogen breath test and the clinical symptoms in patients receiving the maintenance regimen with lactol probiotic showed a better response. The hydrogen breath test turned negative in 93.3 per cent of those receiving lactol compared to 66.7 per cent of the controls. In all the cases receiving lactol, the abdominal pain disappeared completely ( p =0.002). In addition, other GI problems including flatulence, belching and diarrhoea significantly improved in the study group ( p <0.05). Interpretation & conclusions: Based on the preliminary data it seems that adding lactol probiotic to the maintenance therapy of small intestinal bacterial overgrowth patients on routine antibiotic therapy will be beneficial in preventing the complications of this syndrome
