Some of the military terms are related to archery. Many of these terms have disappeared from dictionaries but in the treatises related to archery, you can get information about them. In some Persian texts, these terms (such as عقده، زنده، مرده چلیپا، زیردست، دستکش) are placed next to other famous terms (such as تیر، کمان، ناوک پیکان) that form equivocal appropriateness and they increase the rhetorical value of the texts. In this essay has been attempted to introduce some of these terms and investigated their rhetorical function in the poetry of Persian literature poets. For this purpose, various equivocal appropriateness have been introduced and military terms in Persian texts have been divided into regular categories. In the main part of the essay, examples of equivocal appropriateness based on archery terms are presented.Keywords: Equivocal appropriateness, Military terms, Archery.  Multiple meaning and equivocal appropriateness is a rhetorical devices that depends on the mind of the reader, the greater the reader's vocabulary, the more multiple meanings he will discover. He will notice that in the poetry of some poets, the words are connected with each other and in a network of proportions and this makes the reader will enjoy the text more. Equivocal appropriateness can be divided semantically such as Astronomy, medicine, Philosophy, logic …. Some of these equivocal appropriateness are based on military terms. Military terms are divided into several categories: 1) weapons of war such as arrow, bow, mace, and ax … 2) Warning and notification tools such as drum, Trumpet … 3) Terms related to stratagem 4) Terms related to military ranks such as colonel, soldier, 5) Terms related to horses.Some of the military terms are related to archery.

In the main part of the essay, examples of equivocal appropriateness based on archery terms are presented.Therefore, by reading this article, the reader can find out that words and terms are used in literary texts that sometimes cannot be recognized due to the time gap. Some of these terms are not recorded in dictionaries. And this makes it more difficult for readers to find them. The treatises written in the past about different branches of science are a good source for discovering these terms. Some of these terms have been used by poets with Equivocal appropriateness’s.  Their discovery will increase the rhetorical aspects of the texts. Some of these terms are related to shooting and archery, which poets have used in different waysFrom this article, it can be concluded that in the treatises on shooting and archery terms are used that have often disappeared from the dictionaries, such as عقده، چلیپا، بازو، دستکش، زیردست، لزوم، لازم، آشنا، بحر، میدان، چست، خال، حکم، مهره، زنده، مرده، زلف، گیسو، زاغ، شاخ، گرد، سحر، خاکی، خانه، گسسته، دراز، مجرا، معلّق، سینه، بیضه، رخ، سپری، پلک و چاشنی. In some verses, these terms are placed next to other famous terms in the field of shooting. Due to readers' unfamiliarity with these terms, these analogies are often not mentioned. In this research, in addition to introducing these terms, their rhetorical function in the poems of Persian poets has also been discussed.

Background & Objective: Although the concordance between immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) is generally high for HER2 scores of 3+ and 1+, discrepancies remain in cases scored as IHC 2+. This study aimed to evaluate HER2/neu gene amplification using FISH in breast cancer patients with IHC 2+ and to examine associated clinicopathological characteristics.Methods: This retrospective study included tissue samples from 369 women diagnosed with invasive ductal carcinoma of the breast and an equivocal HER2 IHC score (2+). These samples were further assessed for HER2 gene amplification using FISH. Demographic and clinicopathological data were collected and analyzed.Results: The mean age of patients was 51.6 ± 2.6 years. FISH analysis revealed no HER2 amplification in 72.6% of IHC 2+ cases, while 27.4% demonstrated amplification. HER2 amplification was significantly associated with younger age, higher histological grade, lymph node involvement, larger tumor size, and reduced survival rate. No significant association was observed between HER2 amplification and margin involvement.Conclusion: HER2 amplification is a significant predictor of aggressive tumor behavior and may necessitate targeted therapy. In cases with IHC 2+, both FISH results and relevant clinicopathological features should be considered prior to initiating trastuzumab treatment.

High-Power Lasers (HPLs) are capable of creating a plume containing tissue debris, vapor, and viruses (HPV, HIV, etc. ) which is liberated into the surrounding environment and may have a potential role in infection transmission. The employment of these dental lasers is an equivocal concern during the new Coronavirus Disease 2019 (COVID-19) outbreak. Since many oral tissues are highly potential reservoirs of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), this study was conducted to scrutinize the possibility of dissemination of this virus through the plume in dental laser treatments during the COVID-19 pandemic. The current evidence shows while the employment of laser is an effective and comfortable tool for dental treatments, it holds some inherent hazards such as producing airborne contaminants. With HPV, HIV, and other viruses already detected in laser plume and considering the presence of ACE2 receptors in the oral cavity, there is a potential risk in laser treatments to produce infectious plume, which may possibly contain SARS-CoV-2. The SARS-CoV-2 virus can potentially be liberated in the plume during dental application of HPLs in suspected or confirmed cases of COVID-19. While the amount of aerosol may be different from other routine dental instruments, this modality should be used with crucial care during the COVID-19 outbreak. In this regard, safety precautions in laser application should be rigorously maintained during the COVID-19 outbreak.

The legislators primarily aim to compile clear and unambiguous rules,however, it is in some cases inevitable to use equivocal and paradoxical terms. The reasons for such an occurrence are galore. In the present study, this subject was investigated in the Iranian Constitution since prior to Constitutional Revolution to the present time, and some examples were brought. In each case, the basis of the equivocality and representation in constitution was separately investigated and the motives were discussed. One of the aspects of using such terms indicated the lack of unanimity among the working groups over using the clear and unambiguous terms insofar as no conclusion has been drawn in socio-political discussions, and no unanimity over the conflicts has been reached. Therefore, ambiguity of the socio-political level has entered into a legal level and has affected the legal texts. In other words, members of working political groups haven't still come upon an agreed solution for the controversial issues, and choosing each way solely will satisfy one of the parties, resulting in an imbalance of powers in favor of one party. Hence, solving such a controversy is achieved through delaying precise expression of the will by each party and postponing the decision-making over the issue, all of which is earned by using equivocal phrases and silencing the issue,discussing such issues will result in the futility of the Constitution. The article ultimately recommended that jurists take into account the principle of silence and equivocality in constitution,

In this paper, through exploring the problem of equivocal types and its historical roots in Islamic Peripatetic school, we will explain the differences between Khajeh Nasir’s approach to equivocal types and Avicenna’s one; and show that such differences result from Sohrevardi’s criticisms and his belief in the priority of essence.On the one hand, Khajeh Nasir embraces Sohrevardi’s criticism of Avicenna, and on the other, he never could accommodate modulation and gradation of essence in the framework of Peripatetic school. Thus, he considers the equivocal types as required common accidental of their tokens. In this paper, it has been shown that, firstly, Khajeh Nasir borrows this idea from the matter of the relation of genus and differentia and of accident and Aristotle’s accidental categories. Secondly, to embrace such idea epistemologically results in inconformity between subject and object form Peripatetic point of view. Furthermore, from theological point of view, it paves the way to Ibn Kamooneh’s doubt.

Introduction: Acute appendicitis is one of the main cause of acute abdomen referral to emergency departments worldwide. And despite recent investigations in diagnostic methods, appendicitis accurate diagnosis is still one of the controversial issues in surgery. It is estimated that incidence of negative appendectomy in men and women varies from 8% to 45%. In this study we compared the accuracy of ultrasound and Computer tomography scan (CT scan) in patients suspected to acute appendicitis.Material and Methods: In this cross-sectional study, patients were enrolled the study who were referred to emergency department of Imam Reza hospital with clinical suspicion ofacute appendicitis. Radiologic result of patients underwent surgery for acute appendicitis was compared with pathology reports. Data were analyzed by chi-square and T-student tests in SPSS16.Results: Overall 46 males and 35 females (mean age: 24.6±8.9 years) were studied. Sensitivity, specificity, positive predictive value and negative predictive value of abdominal ultrasound for acute appendicitis were 73.9%, 62.5%, 94.4%, and 78.2%, respectively. These values for CT scan were 88.8%, 80.9%, 94.1% and 66.6%, respectively.Conclusion: our results showed that CT scan is more accurate than sonography for diagnosis of acute appendicitis, particularly in female patients and patient with nonspecific symptoms.

Background: Human epidermal growth factor 2 (HER2) is known to be an important prognostic factor in breast cancer. Numerous studies have shown HER2+ breast cancers have reduced overall survival and recovery time, as well as the efficacy of anti-HER2 therapies along with chemotherapy in improving disease outcomes. For this reason, it is recommended that all patients with breast cancer should be evaluated for HER2 status. This study aimed to assess the HER2 gene amplification by the CISH method in evaluating the HER2 status in patients with immunohistochemistry (IHC) 2+ (equivocal) results. Methods: This retrospective cross-sectional study examined HER2 status based on the Chromogenic in situ hybridization (CISH) method in 280 breast carcinoma samples with an initial 2+ (equivocal) score in IHC. The relationship between HER2 amplification and hormone receptors (estrogen and progesterone) and Ki67 level was also investigated. Results: In sixty samples (21. 4%), the HER2 gene was amplified based on the CISH method. The majority (215, 76. 8%) of the samples were negative and 5 (1. 8%) samples were indeterminate. No significant relationship was observed between HER2 amplification, estrogen receptor (p=0. 143), and Ki-67 protein level (p=0. 977). There was a significant inverse relationship between HER2 amplification and progesterone receptor positivity (p=0. 007). Conclusion: These results demonstrate that CISH is a helpful method to assess HER2 status in equivocal breast cancer and is positive (amplified) in about 21. 4% of them.
