Hürthle cell carcinoma: current perspectives.

Hürthle cell carcinoma (HCC) can present either as a minimally invasive or as a widely invasive tumor. HCC generally has a more aggressive clinical behavior compared with the other differentiated thyroid cancers, and it is associated with a higher rate of distant metastases. Minimally invasive HCC demonstrates much less aggressive behavior; lesions <4 cm can be treated with thyroid lobectomy alone, and without radioactive iodine (RAI). HCC has been observed to be less iodine-avid compared with other differentiated thyroid cancers; however, recent data have demonstrated improved survival with RAI use in patients with HCC >2 cm and those with nodal and distant metastases. Patients with localized iodine-resistant disease who are not candidates for a wait-and-watch approach can be treated with localized therapies. Systemic therapy is reserved for patients with progressive, widely metastatic HCC

Cohesion in Munajat Namih by the Saint of Harat

Today, Linguistic researches on literature play an important role in studying each language. Linguistic analysis of literature has interested critics to give a better knowledge of literary texts and their stylistic features via different linguistic approaches. This paper aims at investigating textual cohesion in “Munajat Namih” by Khajih Abd-Ollah Ansari, the poet and mystic in ninth and tenth century, based on Halliday and Hasan (1985,1976). Having selected 30 cases of Munajats  from Munajat Namih to discover cohesive devices, we have calculated the frequency of their functions and concluded that the most basic cohesive devices in it are personal pronouns. Repetition of the same word is ranked in the second place, and additives are ranked in a third place. Furthermore, collocation and verbal ellipsis are from among important cohesive devices in Munajat Namih. In fact, because of its being a poetic and mystic prose, the cohesive devices had been used in the form mentioned

Comparison of 1 versus 3 Days Post-operative Catheterization after Anterior Colporrhaphy

With attention to the fact that after anterior colporrhaphy surgery and stitches on vaginal mucus, inserting urinary catheter is requested, according to scientific references and in order to prevent from urinary retention, it has been said that the catheter should be inserted for 3 days. But inserting the catheter leads to infections of bladder and pain. So, in the present study, we compared the removal of the catheter 24 hours versus 72 hours after the surgery, considering urinary infections, urinary retention, patient’s ease and hospitalization. Within two groups of 70 patients, which has been assimilated based on basic factors (devided into two groups accidently with excel table) urinary catheter fixed for 1 and 3 days. After that, patients were compared considering urinary retention, urinary infections and the rate of patient satisfaction. Urinary retention was 28.6% in the test group and 22.9% in a controlling group which was not statistically meaningful (P=0.78). Urinary infections were 22.9% in the test group and 34.3% in the controlling group (P=0.42) and the rate of patient’ssatisfactions was 57.1% in the test group and 40% in controlling group (P=0.23). The hospitalization period in the test group and in the control group was 2.91±0.61 and 3.94± 0.59 days respectively with a significant difference (P=0.001). The results showed that short time catheterization is more satisfactory in comparison long catheterizations

Zagreb equienergetic bipartite graphs

Let G be a graph with vertices v1, v2, . . . , vn and let di be the degree of vi. The Zagreb matrix of the graph G is the square matrix of order n whose (i, j)-entry is equal to di + dj if the vertices vi and vj are adjacent, and zero otherwise. The Zagreb energy ZE(G) of G is the sum of the absolute values of the eigenvalues of the Zagreb matrix. Two graphs are said to be Zagreb equienergetic if their Zagreb energies are equal. In this paper, we show how infinitely many pairs of Zagreb equienergetic bipartite graphs can be constructed such that these bipartite graphs are connected, possess an equal number of vertices, an equal number of edges, and are not cospectral.Publisher's Versio

Comparative effect of Pediococcus acidilactici and Lactococcus lactis on growth performance, survival and enzyme activity of western white leg shrimp (Litopenaeus vannamei)

This study was done in Shahid Kiani Marine Aquaculture Development Center, Choebde, Abadan in order to evaluate the effects of Pediiococcus acidilactici, Lactococcus lactis and vitamin C on growth performance, survival, enzymatic activities and immune responses of L. vannamei during three months. Treatments were included control group, Pediiococcus and Lactococcus treatments which fed with diet containing 1×10P9P cfu gP_1P bacteria and vitamin C. At the end of the experiment, the growth factors, immune parameters, digestive enzymes, intestinal, histology of intestine, carcasses and microbial flora (bacterial total count and lactic acid count) were evaluated. The results indicated that administration of lactobacillus had significant effects on the growth factors as the highest weight, increase specific growth rate, relative growth rate, feed conversion ratio and protein efficiency in the shrimps received pediococcus and then Lactococcus (P<0.05). The best immune function was also observed in the shrimps fed by probiotics, so that proteins and hemoglobin̛ hemolymph, phenoloxidase activity and challenged with V. parahaemolyticus showed a statistical difference comparing to the control group and the group received vitamin C (P<0.05). Some digestive enzymes, in pediococcus treatment showed a significant increase when compared to other treatments (P<0.05). Significant changes in bacterial intestinal flora were observed in probiotic groups compared with control and vitamin C groups (P < 0.05). Histological results showed the positive effects of probiotics in the gut (P < 0.05). While these supplements cannot caused to significant impacts on the shrimp carcass composition (P ˃ 0.05). As a result pediococcus group had the best performance among treatments

My place is placeless: Exploring belonging among second generation “Iranians” in Sweden

This thesis investigates sentiments and negotiations of spatial and political belonging among second generation “Iranian” women in Sweden. The analysis draws on feminist and race critical understandings of belonging and is inspired by intersectional theory. The analysis is separated into two categories: place belonging and the politics of belonging. The first explores an agentic emotional relationship to place, while the latter analyses how such a process is disrupted by discursive and politicized ideas of belonging. The latter often causes belonging to be negotiated, whereby many are sent into quests exploring what their “true” belonging is. The analysis proceeds on the assumption that belonging is a different experience for racialized Swedes in comparison to white Swedes. The primary purpose is therefore to investigate how women of “Iranian” heritage in Sweden negotiate their belonging, and what factors influence this process. This includes an exploration of some intersectional positionalities, such as sexuality, gender, racialization, ableism, class, religiosity and double minoritization and how these influence belonging and non-belonging politically and spatially. Semi-structured interviews with the use of photos were employed during a year of fieldwork in Stockholm. Interviews were conducted digitally as well as face-to-face and were therefore not limited to Stockholm. I interviewed 24 women of “Iranian” heritage, among many were ethnic minorities, queer, religious and non-religious, neurodivergent or working-class. This allowed me to analyze how different intersectional positionalities can result in different ways of belonging socio-spatially. This study found that belonging is often spatially re-worked and re-scaled within this group on the basis of various positionalities, such as race, ethnicity, class, gender, ableism, religiosity and sexuality. This is a result of seeking a spatial label that the women feel comfortable claiming belonging to. This shows that there is a socio-political element to place belonging, in which must be negotiated with others. This is demonstrated to be a difficult process, as membership to “Sweden” is ethnicized and guarded based on a variety of factors, which racialized Swedes are often denied belonging to in a multitude of ways

In vitro evaluation of antiviral activity of essential oil from <em>Zataria multiflora</em> Boiss. against Newcastle disease virus

Introduction: The study aimed to investigate the antiviral activity of Zataria multiflora (ZM) essential oil against Newcastle disease virus (NDV) on Vero cells. Methods: The cytotoxicity of ZM essential oil was evaluated by MTT assay. Cells were infected with 100 TCID50 of a field isolate of virulent NDV (JF820294.1). ZM essential oil at concentrations of 1/5000, 1/25 000, 1/125 000 or 1/625 000 was added at different times of infection: 60 minutes pre infection, simultaneously and 60 minutes post infection. Cells were evaluated morphologically. The TCID50, neutralizing index (NI) and HA titer were determined. Results: Cells treated with ZM essential oil in all concentrations 1 hour before or after infection, showed CPE similar to control virus cells. In simultaneous use, cells treated with 1/5000 concentration of the essential oil, remained morphologically normal. TCID50 values of all treatments were very close to that of control virus except for simultaneous administration at concentration of 1/5000 which was about 1000 folds lower. Virus titer in different treatments was exactly the same as control virus titer in Haemagglutination (HA) test. Conclusion: ZM essential oil has some antiviral activity on NDV in vitro, which is possibly by destruction of virus infectivity or inhibition of early phases of viral proliferation cycle.</p

Determination of some nutritional value and organoleptic properties in fruity teas

Fruity teas are popular due to variety in sensory properties as well as their nutritional and therapeutical characteristics. Recently, the worldwide researches related to fruity teas have been considerably developed. In this work, effects of fruit type (apple, quince and pear) and brewing time (10 or 20 min) on some nutritional properties (Mg, Fe and Ca contents, sugars and protein percent) as well as on the sensory attributes of final products were investigated. No chemical preservative, flavoring gents and colorants were added for preparation of the samples. At the end of 10 min brewing, the highest extraction rates of Mg and protein, Fe and sugars, and Ca were observed for pear, apple, and quince, respectively. At the end of 20 min brewing, the greatest extraction rates of Mg and protein, sugars, and Ca were related to the pear, apple, and quince, respectively. Increasing the time of brewing up to 10 min although did not noticeably affect the extraction rate of nutrients from dried fruits (especially for protein content), significantly influence the sensory characteristics (flavor and color) of final products; so that those prepared by 20 min brewing had higher acceptability. Among the fruity teas produced by 20 min brewing, apple had the best sensory acceptability from flavor and color points of view. After that, pear tea from taste and quince tea from color standpoints were realized as the best samples
