Advanced Primary Lymphoma of Oral Cavity: Report of a Case

Abstract Usually the oral manifestations of NHL are secondary to a more widespread involvement throughout the body, however, it can rarely present as a primary lesion in the oral cavity, having 0.1% - 0.2% prevalence. In this paper we report a case of highly proliferative oral non-Hodgkin lymphoma which presented with very mild symptoms, but had a sudden and significant progression in less than two weeks with involvement of all four quadrants of the oral cavity. Keywords Lymphoma; Intra Oral Swelling; Four Quadran

ANALYSIS OF TIME-LAPSE 3-D VSP DATA FOR SEISMIC MONITORING OF CO2 FLOOD IN WEYBURN FIELD, SASKATCHEWAN

This study explores the potential of VSP data in reservoir studies and particularly in separating the effects of CO2 pore pressure and saturation after fluid injection into the reservoir. It helps establishing robust and reliable links between physical properties of hydrocarbon reservoirs and seismic data. It also reduces the uncertainties of the AVA analysis through constructing a detailed model of first-arrival amplitude decay combining geometric spreading, scattering, and inelastic dissipation. The inversion of seismic data reveals anisotropic variations of geometric attenuation (wavefront curvatures and scattering, denoted ) and the effective attenuation parameter () with depth. Statistical analysis of model uncertainties quantitatively measures the significance of these results. This model correctly predicts the observed frequency-dependent first-arrival amplitudes at all frequencies and can be used for reflected waves. Scattering and geometric spreading (focusing and defocusing of wave fronts) significantly affect seismic amplitudes at lower frequencies and shallower depths. Using of complete well logs, a model of P- and S-wave scattering is derived from direct-wave attenuation observations by numerical and analytical methods. Both approaches reveal fluctuations in the transmitted-energy flux within different depth intervals, and particularly at frequencies above 60 Hz. A randomization of well logs suggests that the upper envelope of the transmitted energy flux (corresponding to strongest transmission) is a reasonable estimate for random scattering. The lower envelope corresponding to the strongest reflectivity appears to be a useful characteristic of the fluctuations in the scattered wavefields. Once these ‘random’ and ‘fluctuation’ attenuations are modeled, they can be isolated from the intrinsic and geometric effects. Finally, three amplitude-based methods are used to separate the effects of CO2 pressure and saturation in the Weyburn reservoir. Based on these results, an area close to an injection well within the southern part of the study area is interpreted as having the highest pressure, and the area between the northern and eastern wells show the highest CO2 saturation. Near the center of the study area, the effects of CO2 saturation and pressure appear to be the weakest

Zagovaratelji antropocentrizma i biocentrizma u romanu Barkskins Annie Proulx

As the bedrocks of the French imperialism in North America, the fur trade and the logging industry led to a drastic depletion in the populations of fur-bearing animals, particularly that of the beaver, and massive deforestation on the continent. Examining Annie Proulx’s Barkskins from an ecocritical point of view, this article seeks to investigate the novel’s representations of the detrimental impact of anthropocentrism. We will show that the prevalence of anthropocentrism in New France resulted in the over-harvesting of beavers to procure precious pelts for European markets, where fur clothes were in vogue during the seventeenth and eighteenth centuries. In this scenario, French merchants went from rags to riches at the cost of losing myriads of beavers. On the other hand, our study will also address the indirect endorsement of biocentrism by the indigenous North Americans, who refrained from inflicting irreparable damage on nature in a vast territory in which the European settlers relentlessly cut ancient trees to make their fortunes. Hence, the focus of this article is the distinction between the perspectives on the natural world held by French settlers and Native Americans in Barkskins.Trgovina krznom i šumarska industrija, kao temelj francuskog imperijalizma u Sjevernoj Americi, doveli su do drastičnog iscrpljivanja populacije krznenih životinja, posebno dabrova, te masovnog krčenja šuma na kontinentu. Analizirajući roman Barkskins Annie Proulx s ekokritičkog stajališta, ovaj članak želi istražiti romaneskne prikaze štetnog utjecaja antropocentrizma. Pokazat ćemo da je prevladavanje antropocentrizma u Novoj Francuskoj rezultiralo prevelikim izlovom dabrova radi kvalitetnog krzna za europska tržišta, gdje je krznena odjeća bila u modi tijekom 17. i 18. stoljeća. U ovom su scenariju iz „uboštva“ do bogatstva, francuski trgovci ostvarili bogatstva po cijenu života mnogih dabrova. Naša će se studija također baviti neizravnom afirmacijom biocentrizma među sjevernoameričkim starosjediocima, koji su se suzdržali od nanošenja nepopravljive štete prirodi za razliku od europskih doseljenika koji su na golemom teritoriju nemilosrdno sjekli drevna stabla kako bi stekli bogatstvo. Prema tome, fokus je ovoga članka različito gledanje na prirodni svijet francuskih doseljenika i Indijanaca u romanu Barkskins

The Significance of Love and Selflessness in Iris Murdoch’s Moral Philosophy

As a distinguished philosopher and novelist in the second half of the twentieth century, Iris Murdoch addressed the significance of ethics in her framework of thought. . Murdoch’s moral philosophy was widely acknowledged as a challenge to the prevailing ethical traditions which, she asserted, had failed to present an accurate picture of morality. As a philosopher and literary figure, Murdoch maintained that not only moral philosophy but also literature should depict perceptible pictures of man’s morality. The purpose of this paper is to closely explore Murdoch’s perspective towards the weight of love in moral philosophy. Since she was concerned with ethical issues and man’s confrontation with ethical questions in a world in which religious values and beliefs had been shattered, Murdoch deployed literature to convey the concepts she advocated in her moral philosophy. She contended that literature was capable of sustaining and improving man’s morality. Murdoch was a prolific novelist and playwright authoring 26 novels and 6 plays in which she developed and reflected her philosophical arguments through the portrayal of her intended ethical behavior. This tendency is mostly highlighted in The Flight from the Enchanter (1956), and The Severed Head (1961) in which Murdoch resorts to Plato’s theory of Forms and his idea of the Good to combat the conventional moral philosophy of the twentieth century. Based on the findings of this article, Murdoch intends to depict the significance of freedom and love as the prerequisites of morality in any philosophical system

Assessing the risk perception of COVID-19 among non-infected people attending emergency departments of selected hospitals in western Iran

Objective: It is important to know people’s perceptions of the risks related to coronavirus disease 2019 (COVID-19) for controlling the pandemic. This study aims to assess the risk perception of COVID-19 among non-infected people referred to emergency departments (ED) of hospitals in Khorramabad, Iran during the pandemic and its related demographic factors. Methods: This is descriptive/analytical study with a cross-sectional design. Participants were 380 adults referred to the ED of four hospitals (Shohadaye Ashayer, Shahid Rahimi, Asali, and Shahid Madani) in Khorramabad city in 2021 who were not infected by COVID-19. For data collection, the risk perception of COVID-19 questionnaire was used. Data were described using mean, standard deviation, frequency, and percentage. Chi-squared test was used in SPSS v.22 software to find the related demographic factors. Results: It was found that 5 people (1.3%) had a moderate perception, 206 (54.2%) had good perception, and 169 (44.5%) had high perception. No one had poor risk perception. According to them, “own knowledge and experience” was the most effective factor in preventing COVID-19 followed by “the advice of experts in the media” and “the advice of friends and family”. Chi-squared test results showed a significant difference in risk perception among people in terms of age (P=0.002) and marital status (P=0.001); the age group <25 years and single people had lower risk perceptions. Conclusion: The risk perception of COVID-19 in people referred to the EDs in western Iran is at good level but is not high. It is necessary to improve their risk perception by education and increasing awareness on social media

A mini-review on the most important effective medicinal plants to treat hypertension in ethnobotanical evidence of Iran.

Nowadays, cardiovascular diseases are highly prevalent in human communities. Hypertension is a multifactorial disease which causes a mortality twice higher than general population. Given the fact that medicinal plants have long been used to treat hypertension and are currently being administered for this disease, we sought to report the mostly effective and important medicinal plants on hypertension therapy in ethno-botanical evidence of Iran. In this study, hypertension, Iran, ethno-botany, medicinal plants, and traditional medicine were used as key words to search in Web of Science, PubMed, Scopus, EBSCO and EMBASE to select relevant articles. The findings of this study indicated that in Iran 40 plants in various provinces are used to treat hypertension. Because medicinal plants in this study contain effective compounds and have long been used to treat and reduce hypertension, they could provide suitable research arrangements for controlling hypertension, while effective natural drugs could be developed to control hypertension if their properties are confirmed in pharmacological studies

Association of Anticardiolipin Antibodies and Extent of Coronary Artery Disease in Military Personnel and Non Military Population With Acute Coronary Syndrome

Introduction: Cardiac involvement is one of the chief complications considerably contributing to the morbidity and mortality of patients with systemic autoimmune diseases. Anticardiolipin antibody is a marker of elevated myocardial infarction risk and it also predicts post cardiac intervention risk. In the current study, we aimed to evaluate the association between anticardiolipin IgM and IgG levels and atherosclerotic involvement of coronary arteries.Methods: Patients with acute coronary syndrome admitted to a military hospital were included in the study. Patients were categorized to military personnel and non-military personnel. Laboratory data including lipid profile, blood sugar, anticardiolipin IgM and anticardiolipin IgG were verified. Existence and the extent of Coronary Artery Disease (CAD) were defined according to angiographic findings. The relationship between anticardiolipin antibody levels and the number of vessels were evaluated.Results: According to our sample population calculation, we performed the study on a total of 92 patients. Measurement of both anticardiolipin antibodies (IgM and IgG) in military personnel and non personnel patients showed no significant difference. In both military personnel and non personnel groups, there was a significant association between anticardiolipin IgM and IgG levels and number of coronary arteries with significant stenosis. The C Reactive Protein (CRP) level was significantly higher in military personnel.Conclusions: According to the study results, anticardiolipin antibody levels were the same in both military personnel and non personnel. Also systolic and diastolic blood pressures were not significantly different in both groups. Increased CRP level in military personnel may be a warning signal about the possibility of premature CAD in this population, hence aggressive risk factor modification is recommended. Paradoxically lipid profile and FBS levels were more favorable in military personnel, which indirectly reflects their higher state of physical activity

The largest bilateral gemination of permanent maxillary central incisors: report of a case

Gemination is defined as an attempt to make two teeth from one enamel organ. Bilateral presentation of this phenomenon is very rare, with prevalence of 0.01% to 0.04% in the primary, and 0.05% in the permanent dentition. This paper describes a rare case of huge bilateral gemination of permanent maxillary central incisors in a nine-yearold Iranian boy with poor aesthetic. The patient did not have history of anomaly in his primary dentition and in his family either. This type of dental anomaly can cause clinical problems in the form of malocclusion, poor aesthetic, and impaction of adjacent teeth, caries, and periodontal destruction
