OCLC Number/Unique Identifier: 9048248509

Artificial intelligence (AI) is the emulation of human intelligence in computers that have been trained to think and behave like humans. The word may also refer to any computer that exhibits human-like characteristics like learning and problem-solving. Artificial intelligence is intelligence demonstrated by machines, as opposed to natural intelligence, which involves consciousness and emotionality and is demonstrated by humans and animals [1].

Assessment and sensitive analysis of biological water risks in water resources with application of classical mass transfer computations

Published on: 9th June, 2021

OCLC Number/Unique Identifier: 9124650394

Due to the urgent need for water in all parts of industrial or developing societies, water supply, and transmission facilities are suitable targets for biological risks. Given that even a short interruption in water supply and water supply operations has a great impact on daily activities in the community, the deliberate contamination of urban water resources has irreparable consequences in the field of public health, and the economy of society will follow. Unfortunately, most officials in the public health control departments in our country have received limited training in detecting accidental or intentional contamination of water resources and dealing with the spread of waterborne diseases both naturally and intentionally. For this reason, there is low preparedness in the responsible agencies to deal with waterborne diseases during biological risks. In the first step of this research, a review study has been conducted on water biological risks and operational strategies to deal with them. In the following, it has studied how Escherichia coli (E. coli) bacteria spread in aqueous media. In this regard, the kinetic model of the studied microorganism was analyzed based on the implementation of (Fick Law) in polar coordinates and the combination of (Dirac Distribution) with (Legendre polynomial) distribution. Finally, after studying the factors affecting the microbial pollutant emission coefficient, the effects of all three factors of linear velocity, linear motion time period, and angle of motion on the pollutant emission flux and biofilm diffusion time in the water supply network environment were investigated. Studies have shown that the linear velocity parameter of Escherichia coli with a nonlinear relationship has the greatest effects on the release of microbial contaminants.

Simulating the dispersion of poisonous organic chemical compounds in wastewater treatment process through the active sludge method using the TOXChem model

Published on: 24th June, 2021

OCLC Number/Unique Identifier: 9124851637

Naturally, microorganisms decompose the organic material existing in nature, both in the presence or absence of oxygen. The majority of materials such as poisonous chemical compounds, heavy metals, would prevent the treatment process from taking place, lead to the entry of these contaminants into the environment results in the emergence of numerous diseases. In the present study, using the TOXChem4.1 simulation model, attempts were made to simulate a wastewater treatment plant and then assess the dispersions of contaminants including 1,2-Dimethylnaphthalene, 1,3-Dinitropyrene, 1,6-Dimethylnaphthalene, 1,6-Dinitropyrene, and 17a-ethinylestradiol (EE2) in concentrations of a common scenario. The results of computer simulations showed that the EE2 contaminant is of the highest percentage of decomposition among others, due to its wider chemical structure. Consequently, it is clear that such contaminant is of the highest mass in the sludge exiting the treatment plant. In addition, the results of the simulations demonstrated that the highest volumes of gaseous pollutants take place in the modulation and initial sedimentation units.

Comorbidity of alcohol dependence with attention-deficit/hyperactivity disorder and the role of executive dysfunctions

Published on: 30th January, 2018

OCLC Number/Unique Identifier: 7325429171

Background: This study aims to retrospectively investigate the comorbidity of ADHD multiple symptoms (behavioral) with alcohol addiction in a sample of adult alcohol-dependent patients and to test their current attentional skills (behavioral and cognitive). Methods: Thirty-two adult alcohol-dependent patients were examined for ADHD using a semi-structured interview and the Mini Mental State Examination to evaluate attention and inhibition functions. Brown ADD Scales were used to specifically examine ADHD syndrome. Patients were compared with thirty matched control participants selected from healthy population in few measures of attentional control and working memory. Results: 50% of patients showed evidence of primary ADHD symptoms: specifically, 28.12% showed criteria for ADHD highly probable, 12.50% for ADHD probable but not certain and 9.38% for ADHD possible but not likely. Patients also revealed several deficits in the selective visual attention, interference control and verbal working memory compared to the control group. Conclusions: These results revealed that adult alcohol-dependent patients had retrospectively high comorbidity with ADHD and significant current deficits of the executive functions. These findings suggest the importance of early diagnosis and treatment of ADHD in order to prevent the development of alcohol dependence.

The forgotten player in the surgical history

Published on: 13th May, 2019

OCLC Number/Unique Identifier: 8164026356

The research concerning a preventive treatment of an osteoporitic femoral neck fracture started in 1990 because the surgical procedure of unstable femoral neck fractures is difficult. After effects are frequent and their number will increase in the next decade. The goal is to reinforce the femur with a biomaterial acting as a bone graft. Natural coral is bioresorbable and biocompatible. It acts as an autofocus bone graft for reconstruction of either cortex or cancellous bone and increases their mechanical resistance. This work shows evidence of new bone formation in an osteoporotic unbroken femoral neck femur. Consequently, the preventive surgical treatment of osteoporosis should be taken in consideration [1]. The purpose of this work is to show the results on the mineralization of the cancellous bone of an upper femoral metaphyses when a natural biomaterial is set in an unbroken osteoporotic femoral neck. Summary: Mrs. L is an 84 years old lady. Her osteoporotic unbroken right hip was grafted preventively with a biomaterial in order to prevent the high risk of break in case of fall. The biomaterial used is beads of natural coral. The reasons of this preventive treatment is discussed, as well as the choice of the biomaterial. The results are shown including a two years follow up. Brief History: Before going further, few words of history. Three centuries BC, an Aristote’s follower, Théophraste thinks that Natural coral is a petrified plant. For Ovide natural coral is a soft alga air-hardening. Al Biruni classes it among animals, because that respond to touch. At the beginning of the XVIIth century, Marsigli thinks that they are flowers which open out there in aquarium. The French Jean-André Peyssonnel, a young naturalist, says as Biruni, that in fact, corals are animals. At last, Buffon claims: These marine plants, were classified first in the rank of minerals, then in those of plants, and finally in that of animals. Natural coral is obviously an animal. After the Second World War, coral samples were analyzed by American scientists. Among 800 corail species, 3 where specially analyzed: Acropora, Porites and Libophylia. Mrs Nane Guillemin did in France her PHD on natural coral and with her team made a complete fundamental analysis (physical, chemical and biological properties) of the material, while the American scientists worked on the chemical bone’s properties. In France, Pr Ohayoun and his team worked on the surgical application in the dental field, Dr. Yves Cirotteau in the orthopedic surgery, specifically for osteoporotic disease and for the traumatologic field

Vigour of CRISPR/Cas9 Gene Editing in Alzheimer’s Disease

Published on: 5th October, 2018

Ailment repairing regiments has turn out to be arduous, despite a plenty of understanding and knowledge acquired in the past relating to the molecular underpinnings of Alzheimer’s disease (AD. Umpteen clinical experiments targeting the fabrication and accumulation have been turned fruitless to fit potency standards. The tests aiming beta-amyloid hypothesis also turned futile making it exigent for further handling tactics. The new emanation of a comparably candid, economical, and punctilious system known as gene editing have showed light in path of cure for AD by CRISPR/Cas9 gene editing. Being a straight approach this procedure has already shown assurance in other neurological disorders too such as Huntington’s disease. This review standpoint the immanent service of CRISPR/Cas9 as a remedial option for AD by aiming on specific genes inclusive of those that induce early-onset AD, as well as those that are substantial risk components for late-onset AD such as the apolipoprotein E4 (APOE4) gene.

Published on: 5th November, 2019

OCLC Number/Unique Identifier: 8330461480

The purpose of this study is to highlight the drug abuse hazards and preventive aspects. From a public health perspective, substance abuse has long been a source of major concern, both for the individual’s health and for wider society as a whole. The UK has the highest rates of recorded illegal drug misuse in the western world. In particular, it has comparatively high rates of heroin and crack cocaine use. Substances that are considered harmful are strictly regulated according to a classification system that takes into account the harms and risks of taking each drug. The adverse effects of drug abuse can be thought of in three parts that together determine the overall harm in taking it. Some addictive substances are more damaging to the skeletal system along with the others. In this review article, an effort has been taken to elaborate the effects of addictive drugs on human highlighting these most problematic substances for bones and also the promising potential prevention aspects of drug abuse.

Published on: 13th April, 2020

OCLC Number/Unique Identifier: 8576369620

Aim: This study calculated the effects on serum phosphorus (P) levels, after treatment with either of 2 drugs: the erythropoietin (Epo) and the antioxidant lazaroid (L) drug U-74389G. The calculation was based on the results of 2 preliminary studies, each one of which estimated the certain influence, after the respective drug usage in an induced ischemia reperfusion (IR) animal experiment. Materials and methods: The 2 main experimental endpoints at which the serum P levels were evaluated was the 60th reperfusion min (for the groups A, C and E) and the 120th reperfusion min (for the groups B, D and F). Specially, the groups A and B were processed without drugs, the groups C and D after Epo administration; whereas the groups E and F after the L administration. Results: The first preliminary study of Epo presented a non significant hyperphosphoremic effect by 2.46% + 2.02% (p - value = 0.2168). However, the second preliminary study of U-74389G presented a non significant hypophosphoremic effect by 1.09% + 2.01% (p - value = 0.5771). These 2 studies were co-evaluated since they came from the same experimental setting. The outcome of the co-evaluation was that L is at least 0.4455128-fold [0.4445589 - 0.4464687] more hypophosphoremic than Epo (p - value = 0.0000). Conclusions: The anti-oxidant capacities of U-74389G ascribe at least 0.4455128-fold [0.4445589 - 0.4464687] more effects than Epo (p - value = 0.0000).

Comparative study of carboxylate and amide forms of HLDF-6 peptide: Neuroprotective and nootropic effects in animal models of ischemic stroke

Published on: 24th July, 2019

OCLC Number/Unique Identifier: 8195621281

Aim:The work was to perform a comparative study of the neuroprotective and nootropic activities of two pharmaceutical substances, the HLDF-6 peptide and its amide form (HLDF-6-NH2). Materials and Methods: We used in the study healthy adult male Wistar rats aged 180–200 days weighing 280–300 g. We modelled ischemic stroke in rats by chronical occlusion of carotid arteries. Solutions of the HLDF-6-NH2 and HLDF-6 peptides were administered intranasally. Cognitive functions we assessed with Novel object recognition test and Morris maze. Results: The amide form of HLDF-6 peptide is more efficient: the neuroprotective activity of HLDF-6-NH2, evaluated by improvement of cognitive functions in animals, surpassed that of the native HLDF-6 peptide. A dose of 250 µg/kg of HLDF-6-NH2 peptide resulted in practically complete restoration of the disturbed functions. In the model of ischemic stroke, the amide form of the peptide significantly excelled the reference substance mexidol both in the effective dose and biological activity. Conclusion: The results of study of the agent allow hoping for its success in further clinical investigation. In view of high demand for the agent and in case of successful clinical trials, it will surely become widely used in clinical practice in treatment of IS.

Carbonic Anhydrase I modifies SOD1-induced motor neuron toxicity in Drosophila via ER stress pathway

Published on: 1st August, 2019

OCLC Number/Unique Identifier: 8195612915

Background: Drosophila models of amyotrophic lateral sclerosis (ALS) have been widely used in understanding molecular mechanisms of ALS pathogenesis as well as discovering potential targets for therapeutic drugs. Mutations in the copper/zinc superoxide dismutase (SOD1) cause ALS by gain of toxic functions and induce toxicity in fly motor neurons. Results: In this study, we have determined that human carbonic anhydrase I (CA1) can alleviate mutant SOD1-induced motor neuron toxicity in the transgenic fly model of ALS. Interestingly, we found that motor neuron expression of CA1 could independently induce locomotion defect as well as decreasing the survival rate. In addition, CA1-induced toxicity in motor neurons is anhydrase activity-dependent. Mechanistically, we identified that both SOD1- and CA1-induced toxicity involve the activation of eIF2α in the ER stress response pathway. Downstream activation of the JNK pathway has also been implicated in the induced toxicity. Conclusion: Our results have confirmed that SOD1-induced toxicity in fly motor neuron also involves endoplasmic reticulum (ER) stress pathway. More importantly, we have discovered a new cellular role that CA1 plays by antagonizing mutant SOD1-induced toxicity in motor neurons involving the ER stress pathway. Such information can be potentially useful for further understanding disease mechanisms and developing therapeutic targets for ALS.

Tamsulosin and Dementia in old age: Is there any relationship?

Published on: 1st October, 2019

OCLC Number/Unique Identifier: 8280929913

Tamsulosin is used to treat Benign Prostatic Hyperplasia (BPH), prescribed annually to about 12.6 million patients worldwide. It is an alpha-adrenergic antagonist that reduces the tone of the prostate smooth muscle involved in the pathophysiology of BPH. By acting on alpha 1A receptors, predominant in the prostate, tamsulosin also acts on receptors present in the brain. This study consisted of a literature review aimed at disseminating scientific knowledge about the relationship between the use of tamsulosin and the onset of dementia. PubMed, Scopus, Scielo, Embase, and Web of Science studies involving dementia in patients using tamsulosin in the last five years were selected. The review showed a risk correlation and a higher incidence of dementia in treated patients. The risk ratio, when compared to other medicines, approached 1.20. In conclusion, it was identified the need for clinical trials with higher sampling power to increase relational significance due to the high prevalence of BPH and the extensive use of tamsulosin in elderly patients with the disease.

Protection from the Pathogenesis of Neurodegenerative Disorders, including Alzheimer’s Disease, Amyotrophic Lateral Sclerosis, Huntington’s Disease, and Parkinson’s Diseases, through the Mitigation of Reactive Oxygen Species

Published on: 4th November, 2019

OCLC Number/Unique Identifier: 8302209826

The biological changes caused by oxidative stress (OS) are known to be involved in the etiology of neurodegenerative disorders, including Alzheimer’s disease, amyotrophic lateral sclerosis, Huntington’s disease, and Parkinson’s disease. The brain is particularly vulnerable to OS due to its high lipid content and extensive consumption of oxygen. OS processes, particularly the excessive production of reactive oxygen species (ROS), play a critical role in how neurodegenerative disorders develop. This is evidenced by in vivo studies investigating various biomolecules related to OS, such as products of lipid and DNA oxidation. Accordingly, ROS can also cause oxidative-related damage in neurodegenerative disorders, including dopamine auto-oxidation, mitochondrial dysfunction, glial cell activation, α-synuclein aggregation, excessive free iron, and changes in calcium signaling. Furthermore, excessive levels of cellular oxidants reduce antioxidant defenses, which in turn propagate the cycle of OS. As such, it is increasingly important to determine the linkage between a high intake of antioxidants through dietary interventions and a lower risk of developing neurodegenerative diseases. Indeed, in addition to modulating the immune system, optimal nutritional status is capable of changing various processes of neuroinflammation known to be involved in the pathogenesis of neurodegeneration. Accordingly, a better understanding of the role ROS plays in the etiology of neurodegeneration is needed, along with the identification of dietary interventions that may lead to improved therapeutic strategies for both the treatment and prevention of neurodegenerative disorders. Therefore, this review presents a comprehensive summary of the role of ROS in the pathogenesis of neurodegenerative disorders. In addition, nutrients believed to be useful for mitigating and counteracting ROS are discussed.

Immunohistochemical expression of Nestin as Cancer Stem Cell Marker in gliomas

Published on: 11th November, 2019

OCLC Number/Unique Identifier: 8457474432

Background: Gliomas represent the most frequent primary tumors of central nervous system (CNS), contributing to more than half of the incidence of brain tumors. Cancer stem cell markers (CSC) identify a group of patients at high risk for progression. Nestin is an intermediate filament (IF) protein was first described as a neural stem cell/progenitor cell marker. Nestin-positive neuroepithelial stem cells are detected in the subventricular zone of the human adult brain and they remain mitotically active throughout adulthood. The expression of Nestin in gliomas has been suggested to be related to dedifferentiation, improved cell motility, invasive potential and increased malignancy. This study aims to investigate Nestin immunohistochemical expression in different types of glioma and its correlation with different clinicopathological parameters. Materials and Methods: Nestin immunostaining was studied in 60 specimens of glioma using avidin-biotin peroxidase method. Results: Nestin was strongly expressed in 11/60 (18.33%), moderately expressed in 29/60 (48.33%) and weekly expressed in 15/60 (25%) of studied gliomas. A significant positive correlation was found between Nestin expression and histologic type (p < 0.001) and increasing grade of gliomas (p < 0.001). Conclusion: Increased Nestin expression is correlated with tumor progression, increasing grade and poor prognostic parameter of glioma. Nestin is a useful marker for detection of CSC in high-grade glioma which is responsible for resistance to chemo-radiotherapy and may serve as a predictor for patient outcomes.

Comparison of resting-state functional and effective connectivity between default mode network and memory encoding related areas

Published on: 24th April, 2020

OCLC Number/Unique Identifier: 8589567444

Currently brain connectivity modelling, constructed from data acquired by non-invasive technique such as functional magnetic resonance imaging (fMRI), is a well-received approach to illustrate brain function. However, not all connectivity models contains equal amount of information. There are two types of connectivity model that could be constructed from fMRI data, functional and effective connectivity. Effective connectivity includes information about the direction of the connection, while functional connectivity does not. This makes interpretation of effective connectivity more meaningful than functional connectivity. The objective of this study is to show the improvement in interpretability of effective connectivity model in comparison to functional connectivity model. In this study, we show how the difference in the information contained within these two model impacts the interpretation of the resulting connectivity model by analyzing resting-state fMRI data on episodic memory-related cognitive function using CONN Toolbox bivariate correlation measurement for functional connectivity analysis and Tigramite causal discovery framework for effective connectivity analysis on an episodic memory related resting-state fMRI dataset. The comparison between functional and effective connectivity results show that effective connectivity contains more information than the functional connectivity, and the difference in the information contained within these two types of model could significantly impact the intepretation of true brain function. In conclusion, we show that for the connectivity between specific pair of brain regions, effective connectivity analysis reveals more informative characteristic of the connectivity in comparison to functional connectivity where the depicted connectivity lack any additional characteristic information such as the direction of the connection or whether it is a unidirectional or bidirectional. These additional information improve interpretability of brain connectivity study. Thus, we would like to emphasis the important of brain function study using effective connectivity modelling to obtain valid interpretation of true brain function as currently a large body of research in this field focuses only on functional connectivity model.
