It required the literary man to base his artistic output on a basic basis from which to achieve literary creativity, and literary trends and currents have varied, specifically in the postmodern period, which directed its attention to margins and the casual things. Accordingly, we will try to discover and search for what was rejected and excluded by the literary schools, while symbolism school was interested in and considered it as an original and a reference for them. There are some technical procedures that symbolism adopted and applied that were excluded and marginalized before, as it constitutes for them aesthetic values, literary pleasure and a special emotional pleasure. Therefore, we find that they relied on music and the mysterious feelings it evokes in the mind that are difficult to express in ordinary language. They (Symbolism school) found a new kind of authority to write the poetry, specifically after feeling freedom and openness to unlimited horizons.

The study aimed to evaluate the nutritional composition and the efficacy of phytase transgenic corn. Ten-month old castrated Bama boars and replicated a 6×6 Latin square design were used to evaluate the effect of phytase on utilization of calcium of phosphorus. Six-dietary treatments included: Phosphorus adequate control diet (PC), PTC0 (low-phosphorus diet), PTC500 (lowphosphorus diet with 500 FTU phytase/kg in PTC), PTC1000 (low-phosphorus diet with 1000 FTU phytase/kg in PTC), PTC5000 (low-phosphorus diet with 5000 FTU phytase/kg in PTC), microbe500 (low-phosphorus diet with 500 FTU phytase/kg from Aspergillus Niger). Contents of the proximate components, minerals, vitamins and amino acid of PTC did not differ from CC. The PTC has lower concentrations of phytate phosphorus than CC, the apparent digestibility of calcium and phosphorus of the PTC0 group is lower (p<0.05). No obvious dose-dependent relationship about the apparent digestibility of calcium and phosphorus showed among PTC500, PTC1000 and PTC5000. Therefore, the nutritional compositions of PTC had substantial equivalence to that of control corn except for phytate phosphorus concentrations, the PTC addition can improve the apparent digestibility of phosphorus and calcium and reduce the excrement of inorganic phosphorus, PTC might be an economically efficient way to decrease environment pollutions.

There is a deep-rooted correlation between refractory epilepsy in pediatric age and intelligence development. However, little is known about whether surgical procedures used in pediatric epilepsy treatment can affect Intelligence Quotient (IQ) or not. Factors that might influence postoperative IQ are also a matter of study in several articles. To tackle these issues, a systematic review with meta-analysis was conducted with the terms “epilepsy”, “epileptic”, “surgery”, “surgical”, “Wechsler Scale” and “intelligence tests” in PubMed, the Cochrane Library, EMBASE and Clinical Trials.gov. A descriptive data synthesis was carried out to address each of the objectives and then a metaanalysis using a random effects model was conducted. A meta-regression was performed to ascertain possible factors that could influence postoperative IQ. The meta-analysis of the studies included found a mean difference between postoperative and preoperative full-scale IQ values of 1.014 standardized points (p < 0.001). Among all the articles regarding curative surgeries, only three reported an overall significant improvement in IQ after surgery. Regarding palliative procedures, both studies with anterior corpus callosotomy reported a significant improvement in full-scale IQ values two years after surgery. The meta-regression performed did not find any predictors of change in full-scale IQ.
Retinoblastoma protein regulates carcinogen susceptibility at heterochromatic cancer driver loci
Authors: Wong Ka Man , King Devin A , Schwartz Erin K , Herrera Rafael E , Morrison Ashby J
Published: January 2022

Carcinogenic insult, such as UV light exposure, creates DNA lesions that evolve into mutations if left unrepaired. These resulting mutations can contribute to carcinogenesis and drive malignant phenotypes. Susceptibility to carcinogens (i.e., the propensity to form a carcinogen-induced DNA lesion) is regulated by both genetic and epigenetic factors. Importantly, carcinogen susceptibility is a critical contributor to cancer mutagenesis. It is known that mutations can be prevented by tumor suppressor regulation of DNA damage response pathways; however, their roles carcinogen susceptibility have not yet been reported. In this study, we reveal that the retinoblastoma (RB1) tumor suppressor regulates UV susceptibility across broad regions of the genome. In particular, centromere and telomere-proximal regions exhibit significant increases in UV lesion susceptibility when RB1 is deleted. Several cancer-related genes are located within genomic regions of increased susceptibility, including telomerase reverse transcriptase, TERT, thereby accelerating mutagenic potential in cancers with RB1 pathway alterations. These findings reveal novel genome stability mechanisms of a tumor suppressor and uncover new pathways to accumulate mutations during cancer evolution.

Küresel salgın hastalıklar, insanlık tarihinde doğal afetler ve savaşlar kadar yıkıcı etkiler yaratmıştır. Ciddi ekonomik ve siyasal krizler yaratan salgın hastalıklarla mücadelede sağlık politikalarının uygulanış biçimi öne çıkmaktadır. İktidar sahiplerinin ideolojisine göre insan ve toplum sağlığı, dolayısıyla toplumsal refah da yönetilmektedir. Bu noktada, Foucault’un biyo-politika kavramı akıllara gelmektedir. İnsan bedeninin siyasi strateji aracı edilerek ekonomik çıkarlara ulaşma amacı, neo-liberal dönemde ve özellikle sağlık politikalarının yürütülmesinde hala güdülmektedir. Bugün küresel faturası çok ağır olacak olan COVID-19 Pandemisi tekrar siyasi, ekonomik ve sosyolojik sistemleri biyo-politika üzerinden sorgulamamızı gerektirmiştir. Yeni bir virüsten kaynaklanan bu bulaşıcı hastalık, insanların günlük hayat rutinlerini ve toplumların sosyo-ekonomik ilişkilerini de sekteye uğratmıştır. Bu hastalıktan kurtulmak için gözlerin sağlık sektörüne çevrildiği bu dönemde, çalışmamız sağlık politikalarını biyo-politika üzerinden tartışmayı hedeflemektedir.

The current world facing unpredictable problems with different variants of COVID-19; SARS-COV-19 is a significant lung infection caused by a coronavirus. Each type has one or more alterations to distinguish from each other. The viruses, including SARS-COV-19, continuously change the genetic code (mutations) during their genome replication. WHO labelled two variants in that we are experienced with delta (B.1.617.2) variant, now recently the omicron came (B.1.1.529) with highly mutatable strikes on it. So WHO predicted it is more dangerous than previous variants because of its mutatable capability. The mutatable strikes play an essential role in transmissibility. So there is a need to evaluate threatens raised with the new variant, so scientists are working on it. Till now, South Africa noticed major cases positive for the Omicron variant. Based on recent reports, the current paper summarized different properties of the omicron variant with others, including protein structure, diagnosis, spreadability, treatment, and potency of vaccines. Doi: 10.28991/SciMedJ-2021-0304-10 Full Text: PDF

Published: January 2022

The burden of breast and cervical cancer in terms of incidence and mortality in low- and mid-income countries is increasing daily due to late diagnosis, unhealthy lifestyle choices, late presentation, and poor attitude to screening. Early detection increases the chances of survival. This present study assessed Assam women’s breast and cervical cancer screening (CCS) awareness, the practice of breast self-examination (BSE), and uptake of human papillomavirus vaccines. An internet-based cross-sectional questionnaire was utilized to obtain 251 consenting respondents. The mean age of respondents was 27.8 ± 6.91. Only 205 (81.7%) and 110 (43.8%) respondents have satisfactory levels of BCS, and CCS knowledge, respectively. While only 76 (30.3%) respondents had satisfactory BSE practice. Age range (26 – 32 years), tertiary education, and being single were demographic characteristics that influenced knowledge and practice. Though the respondents had a satisfactory knowledge level, screening uptake among respondents is very poor as only 32 (12.7 %) had ever been screened and only 19 (7.6 %) ever been vaccinated. The major reasons for poor screening uptake were “no symptoms” and “not aware of screening location”. Most respondents (227, 90.4 %) are willing to go for screening if well oriented. This presents an opportunity to enhance awareness about screening and vaccination among Assam women. The media/internet and health practitioners can be leveraged to promote the uptake and utilization of screening services and BSE practice. Doi: 10.28991/SciMedJ-2021-0304-5 Full Text: PDF

Authors: Aziz Kamran Mahmood Ahmed
Published: January 2022

Objectives: Patients with Diabetic Kidney Disease (DKD) and foot ulcer have poor prognosis. However, no study have found association of diabetic foot ulcer (DFU) with diabetic kidney dysfunction and their co-existing risk factors. Materials and Methods: This cross sectional study collected the data for 10,680 patients for 15 years. All variables were analyzed biochemically and statistically by standardized methodology. Results: Levels of HbA1c, creatinine, systolic and diastolic blood pressures, microalbuminuria, spot urine protein, and spot urine protein to creatinine ratio were higher among the groups with foot ulcers (p-value < 0.0001 for all). Average ABI was observed to be lower among the groups demonstrating nephropathy and DKD (p=0.025 and 0.022 respectively. DFU was significantly associated with HTN (odds ratio 2.2; 95% CI 1.66 to 2.9; p < 0.0001), nephropathy (odds ratio 4.77; 95% CI 3.53 to 6.5; p < 0.0001) and DKD (odds ratio 4.77 and 6.83; 95% CI 4.6 to 10.2; p < 0.0001). HbA1c of 7.8% was 60% sensitive and 52% specific for the development of DFU. Creatinine of 1.2 mg/dl was 75% sensitive and 48% specific for DFU. Spot urine protein excretion from nephrons of 35 mg/dl was 88% sensitive and 90% specific for the development of DFU. Conclusion: Nephropathy/DKD are risk factors for the development of DFU. With optimal diabetes control, regular and routine assessment of the feet and early screening of diabetic patients for neuropathy, nephropathy, hypertension, dyslipidaemia and other diabetic complications are essential. Doi: 10.28991/SciMedJ-2021-0304-6 Full Text: PDF
An Overview of Central Nervous System Tumours
Authors: Flepisi Brian Thabile , Balmith Marissa
Published: January 2022

Central nervous system (CNS) tumours refer to tumours that occur in the tissues of the brain and/or spinal cord. These tumours arise as a result of abnormal growth of cells and may begin in different parts of the brain or spinal cord. There are many types of CNS tumours, which are further divided into subtypes. Despite decades of research conducted, CNS tumours remain among the deadliest of all cancers. It is most often challenging to treat these tumours, due to the risks involved, and biological characteristics associated with them. The classification, grading, and characterisation of CNS tumour plays a pivotal role in the management thereof. The current review provides an overview of CNS tumours, classification, grading and treatment, as well as their characterisation with specific focus on gliomas, ependymomas, oligodendrogliomas, meningiomas, medulloblastomas, schwannomas, gangliogliomas, and craniopharyngiomas. Doi: 10.28991/SciMedJ-2021-0304-8 Full Text: PDF

Sin duda la sociedad mexicana va cambiado poco a poco derivado de los avances tecnológicos, la globalización, la mundialización de la economía, el flujo de la información en tiempo real, elementos que contribuyen crear de la nuestra una sociedad más crítica, demandante y exigente en cuanto a derechos, rebasando en mucho al gobernante que se quedó con un visión del siglo pasado incluso antepasado en donde reinaba un ambiente de nepotismo, dilación y corrupción, negando con ello que el ciudadano tuviera voz o voto en las decisiones importantes para el desarrollo del País. Sin embargo en pleno siglo XXI ya el panorama es diferente hoy en día se reclama uno de los principales males que en parte fue la decadencia de grandes civilizaciones en la historia de la humanidad como lo es el combate a la corrupción y retomando una frase célebre de Lee Kuan Yew, Primer ministro de Singapur; abogado, estadista y político, él decía algo muy cierto, que impacta pero que prepara para lo siguiente: “Si quieres derrotar la corrupción debes de estar listo para enviar a la cárcel a tus amigos y familiares”

Recently, terrestrial laser scanner (TLS) has been increasingly used to monitor ofdisplacement of high-rise buildings. The main advantages of this technique are time-saving, higherpoint density, and higher accuracy in comparison with GPS and conventional methods. While TLS isordinary worldwide, there has been no study of the capability of TLS in monitoring the displacement ofhigh-rise buildings yet in Vietnam. The paper's goal is to build a procedure for displacement monitoringof high-rise buildings and assess the accuracy of TLS in this application. In the experiments, a scannedboard with a 60 cm x 60 cm mounted on a moveable monument system is scanned by Faro Focus3DX130. A monitoring procedure using TLS is proposed, including three main stages: site investigation,data acquisition and processing, and displacement determination by the Cloud-to-Cloud method (C2C).As a result, the displacement of the scanned object between epochs is computed. In order to evaluate theaccuracy, the estimated displacement using TLS is compared with the real displacement. The accuracydepends on scanning geometry, surface property, and point density conditions. Our results show that theaccuracy of the estimated displacement is within ± 2 mm for buildings lower than 50 m of height. Thus,TLS completely meets the accuracy requirements of monitoring displacement in the Vietnam Standardsof Engineering Surveying. With such outstanding performance, our workflow of using TLS could beapplied to monitor the displacement of high-rise buildings in the reality of geodetic production inVietnam.
