<p class="abstract">Lipomas in head and neck region are common but prevalence in salivary glands is rare with majority in parotid. Sialolipoma is a rare tumour of the salivary gland that is composed of mature adipocytes and normal salivary gland tissue. We report an extremely rare case of sialolipoma of left submandibular gland in a 39-year-old male who presented with complaints of insidious onset gradually progressive swelling in left submandibular region with no pain, discolouration or discharge. On examination, a 5×4 cm soft, non-tender swelling was noticed in (L) submandibular region. Ultrasonography of neck revealed enlarged (L) submandibular gland with hypoechoic area of 5 mm diameter and small areas of echogenic foci with no cervical lymphadenopathy. Contrast enhanced computed tomography (CECT) neck showed a 5.6×2.7×4 cm well defined fat attenuated lesion in (L) submandibular space, suggestive of lipoma with a well-defined enhancing soft tissue component within the lesion. He underwent excision of (L) submandibular gland along with fibrofatty tissue under general anaesthesia. Histopathological examination revealed submandibular gland with normal histomorphological features along with mature adipocytes in fibrofatty tissue. The patient is on regular follow-up with no recurrence.</p><p class="abstract"> </p>

Published: December 2022

One of the greatest causes of death in the globe is tobacco cigarette smoking. Smoking affects hematological markers both acutely and chronically. The current study's objective was to evaluate the severity of the negative effects of cigarette smoking on biochemical traits in healthy smokers. This study included 280 participants, only 56 smokers and 100 non-smokers. They were smoking for three years, the smokers regularly smoked 10 to 20 cigarettes per day. The fully automatic hematological analyzer CELL-DYN 3700 examined the total number of blood cells. White blood cells (p0,001), hemoglobin (p=0,042), mean corpuscular volume (p=0,001), and mean corpuscular hemoglobin concentration (p0,001) were all considerably greater in the smokers. No other measured metrics varied considerably from one another. Red blood cells, white blood cells, hemoglobin, hematocrit, and mean corpuscular hemoglobin were all significantly higher (p0,001) in male smokers compared to female smokers after smoking cigarettes.: Our study concluded that smoking cigarettes continuously has severe negative effects on hematological variables, including hemoglobin, white blood cell count, mean corpuscular volume, mean corpuscular hemoglobin concentration, red blood cell count, and hematocrit. These modifications may be linked to an increased risk of polycythemia vera, atherosclerosis, chronic obstructive pulmonary disease, and/or cardiovascular diseases.
Historicizing Contemporary Capitalism: Future Retrospection and Temporal Estrangement in Kim Stanley Robinson’s New York 2140 and Nora K. Jemisin’s Emergency Skin
Authors: Gilarek Anna 
Published: December 2022

The paper looks at the historicizing approach adopted in two recent science-fiction books: Kim Stanley Robinson’s novel New York 2140 (2017) and Nora K. Jemisin’s novella Emergency Skin (2019). In both, the authors’ present is approached from the vantage point of a speculatively posited future and looked upon as the historical past of the text. The hypothesized temporal distance is meant to challenge and recalibrate the reader’s perception of contemporary capitalism.
Based on Robinson’s and Jemisin’s narratives, the paper discusses the historicity and mimetic potential of science fiction, manifested in the genre’s ability to situate the present as part of a historical process for an enhanced understanding of contemporary trends and their projected trajectories. In the two texts, the dichotomy between the envisioned future and the present-as-past is paralleled by a utopian/dystopian dialectic, wherein the reality of late capitalism is unequivocally identified as dystopian. The utopian and science-fiction perspectives combined produce the effect of cognitive estrangement, which entails a perceptual renewal with regard to capitalism, whose alleged incontestable status is challenged by the exposure of its historical mutability.
The aim of the analysis is to demonstrate that historicizing contemporary capitalism within science fiction may challenge the ideological hegemony of neoliberalism, expose its dystopian features, and indicate possibilities for the transformation of a system that proclaims to have no alternatives. Such historicization may produce an epistemic shift in the reader’s perception of the contemporary socioeconomic reality, by emphasizing both its unrecognized flaws and its (r)evolutionary potential.

Published: December 2022

Background & Objectives: Staphylococcus spp. is a resident flora of the skin and mucosa of humans that can colonize the anterior nares of individuals. This cross-sectional study was conducted to determine the rate and antibiotic resistance pattern of nasal Staphylococcus aureus (S. aureus) carriers among the staff of Fasa hospital, southern Iran.
Materials & Methods: Nasal swab samples were collected from 117 hospital staff working in 12 wards. Microbiological culture method was applied for S. aureus identification. The isolates were confirmed by tuf gene identification using PCR assay. Five isolates were randomly sequenced and phylogenetically analysed using MEGA software. The antimicrobial resistance pattern of the isolates was evaluated using the disc diffusion assay and the amplification of the methicillin resistance (mecA) gene.
Results: The prevalence of S. aureus nasal carriers included 10.26% (n=12). The nasal carriers were identified in the wards of surgery ICU, gynecologic surgery, NICU, pediatric, internal surgery, and emergency. Among them, gynecologic surgery staff had the highest rate of nasal colonization (33.33%). Phylogenetic analysis showed that of five isolates, four had high similarities with each other. Also, the highest rate of resistance was related to penicillin (83.3%), followed by cefazolin (75%), and cephalexin (75%). However, the highest level of susceptibility (100%) was found for vancomycin, cefoxitin, and oxacillin. Furthermore, the methicillin resistance gene (mecA) was highly detected (75%) from the isolates, elucidating oxacillin-susceptible or cefoxitin-susceptible mecA-positive S. aureus (OS-MRSA).
Conclusions: The high rates of OS-MRSA can lead to antibiotic resistance among health care workers tremendously. Moreover, the high similarity probability in phylogenetic analysis shows the possibility of cross-infection between these health care workers, warning to exert effective strategies to control infection spread, especially in the surgery ward.

Background & Objective: Adequate amniotic fluid volume is one of the most important aspects of fetal health and Oligohydramnios refers to amniotic fluid volume that is less than expected for gestational age. The aim of this study was to compare the trend of amniotic fluid changes in the two groups of oral and injectable before and after fluid therapy.
Materials & Methods: In the present study, pregnant women with oligohydramnios in the third trimester referring to Amir Al-Momenin Hospital (Zabol, 2019) were randomly divided into two groups of case. The first group received oral water and the second group was treated with serum therapy. Eventually, all patients underwent ultrasonography and their AFI was recalculated and compared. Data was analyzed using SPSS 20 statistical software.
Results: The results of the study showed that there was no statistically significant difference between the amniotic fluid index before fluid therapy in the oral and injectable (serum therapy) groups (p = 0.426). After fluid therapy, the amniotic fluid index in the oral group was significantly higher than the injected group (p <0.001). Although in both oral and injectable groups, the amniotic fluid index increased significantly after treatment (p <0.001), the increase in the oral group was significantly higher than the injectable group.
Conclusion: The results of this study showed that oral and intravenous fluid therapy improves the amniotic fluid index more than injectable fluid therapy.

Published: December 2022

Diabetic peripheral neuropathy is one of the most common causes of disability in diabetic patients. Applying a method to achieve the highest therapeutic effect in patients is desirable. Therefore, this study aimed to evaluate the impact of leech therapy on diabetic neuropathy of lower limbs in comparison to gabapentin as a standard method. This randomized controlled parallel-group clinical trial was conducted among 40 patients with type II diabetes who were diagnosed with lower limb diabetic neuropathy and referred to specialized outpatient clinics in Babol, Mazandaran province, Iran from 23 September 2020 to 17 March 2021. The patients were randomly divided into two groups. One group was treated with leech therapy and the other group was treated with gabapentin as the standard method. The severity of neuropathy was assessed every 15 days until the 45th day. The Visual Analog Scale (VAS), Neuropathy Symptom Score (NSS), Neuropathy Disability Score (NDS), and Nerve Conduction Velocity (NCV), and Electromyography (EMG) were used for assessing the study outcomes. The repeated measure and Friedman tests were used by SPSS.V.23. The results of our study indicated that pain (P value:0.03), numbness (P value˂0.0001), and paranesthesia (P value:0.01) significantly reduced in patients undergoing leech therapy versus patients taking gabapentin on the 45th day. The total NSS (P value˂0.0001) and total NDS (P value˂0.0001) improved significantly for patients with leech therapy over 45 days compared to the patients with gabapentin. The results of our study showed that using leech therapy for patients with diabetic neuropathy was more effective in improving clinical symptoms and the functions of lower limb muscles and nerves in comparison to gabapentin. The severity and symptoms of neuropathy greatly improved for the patients treated with leech therapy versus patients taking gabapentin.

Authors: Zhylina T. M. , Shevchenko V. L. 
Published: December 2022

Introduction. Nematodes are one of the most abundant groups of the soil and litter fauna in forest ecosystems. The faunal composition may mirror the activity of decomposition pathways and give indications of nutrient status and fertility of soil. Nematodes play an important role in regulating microbial communities and affect the speed and direction of mineralization and humification of plant precipitation.
Aim. Trophic structure of nematode communities from litter in forests of the Mezin National Nature Park was studied.
Materials and methods. Samples litter were collected from June to July 2010 and 2014 in 21 forest ecosystems. Nematodes were extracted by a modified Baermann’s method from the 5-g sample. The exposition time was 48 h. Extracted nematodes were fixed in the triethanolamine–formalin (TAF, 2 % triethanolamine, 7 % formaldehyde solution, 91% water), and mounted on the temporary hydroglyceric slides. Nematode abundance was expressed as specimens per 100 g of dry substrate.
Results. The 46 identified nematode species were divided into five trophic groups: saprobionts, mycohelminths, omnivores, predators and phytohelminths. Saprobionts were both the most diverse and the most numerous. 26 species (56,52% of all species collected) belonged to the this trophic group, proportion in the community was 63,97%. Plectus cirratus, Plectus parietinus, Panagrolaimus rigidus were the most numerous (proportion in the community 24,13%, 9,65% and 8,18% of the total, respectively). P. rigidus occurred in 95,2% of all samples. Aphelenchoides composticola dominated among 10 species of mycohelminths (frequency was 85,7%, proportion in the community 8,99%). Mesodorylaimus bastiani was common аmong the three species of omnivorous nematodes (frequency was 90,48%, proportion in the community 13,74%). Predatory nematodes (5 species) were in 57,1% of samples, proportion in the community together was 3,17%. Only two species phytohelminths (Gracilacus audriellus, Paratylenchus nanus) were found in the analyzed litter samples. They were rare; their frequency was 9,52% and 4,76% respectively. Moreover they were not very abundant (0,12% and 0,08% of total number respectively).
Conclusions. The mycohelminths and saprobionts make an important component of the litter decomposer community of all forest ecosystems in the Mezin National Nature Park. The ratio of mycohelminths to saprobionts (М/S) shows a constant preponderance of saprobionts and was 0,27. Twenty five species (54,35% of all species collected) were high colonization ability, high reproduction rate and high tolerance to disturbances. The trophic diversity index was 2,16. The maturity index was 2,27. These indexes show stability of habitat in the forest litter.

Authors: Salahot Ester  Damiano 
Published: December 2022

The continuous trend of poor mathematics performance in Tanzania has developed different stakeholders' attention, including the Government, to research the possible causes of poor performance. The presence of mathematics anxiety among students is believed to have an impact on students' performance in Mathematics. In this study, the researcher aimed to investigate the effects of Mathematics Anxiety on Mathematics Performance Among Secondary Schools Students in Tanzania. The study employed a sample size of 396 students from six secondary schools in the Arusha City Council. The researcher collected data through structured questionnaires with closed-ended questions distributed to respondents. Respondents' mathematics terminal examination marks were used in this study. The collected data were analysed using descriptive (percentages and mean) and inferential statistics (correlation and multiple regression analysis). The results generally revealed a significant effect of mathematics anxiety on mathematics performance among secondary school students at a 0.05 level of significance (P-Value 0.00 2- tailed). A correlation coefficient r = 0.304 indicate a significant moderate positive relationship between the effects of mathematics anxiety and mathematics performance. The regression equation indicates that mathematics anxiety affects mathematics performance by 46.6% when other factors remain constants. Based on the findings, it was recommended that mathematics teachers be aware of the possibility of mathematics anxiety among their students. Also, further studies that involve a large sample should be conducted to re-confirm the assertion.

Authors: Bessolicyna E. , Harina A. 
Published: December 2022

The Potato spindle tuber viroid infects potato plants, causing a serious damage to agriculture by reducing yields. Therefore, there is a need to identify this pathogen. Viroids are RNA molecules and so cannot be detected with the immunological methods and the classical PCR. The aim of this work is to develop a method for detection of the Potato spindle tuber viroid. Primers have been selected for the reverse transcription reaction and the subsequent PCR, the annealing temperatures and the size of the amplified fragment have been calculated. Primers and reaction conditions have been tested on plant material. PCR products of the calculated size have been obtained. Determination of their nucleotide sequence confirmed the identification of the genetic material of the Potato spindle tuber viroid. Thus, this PCR test system can be used for detection of the Potato viroid and become the basis for detection of other
vegetable crops’ viroids.
