Gender, Genre and the Female Gothic: Resisting Patriarchal Norms in Angela Carter’s “The Bloody Chamber” and Charlotte Perkins Gilman’s “The Yellow Wallpaper”
Authors: Ağır Barış
Published: October 2023

The female gothic reinterprets works by female authors by fusing feminism and the study of gothic literature. In actuality, it represents a significant advancement in the study of gender in Gothic literature. In works written in the gothic style by women, the oppression of women in patriarchal society is reflected, and the destruction of women at the hands of patriarchy is emphasized throughout gothic art; in this sense, the resilience of the female gothic protagonists in the face of adversity symbolizes their maturation as women. Based on this context, this research attempts to compare "The Bloody Chamber" by Angela Carter with "The Yellow Wallpaper" by Charlotte Perkins Gilman from the standpoint of the feminine Gothic fiction. The dark tragedies that await women in patriarchal culture are explored by Carter and Gilman in ways that transcend beyond the normal boundaries of the gothic genre. By contrasting the narratives, this study aims to show how women begin to question and even demolish patriarchal chauvinism and move away from their subservient position in patriarchal society.

‘Made in Airbnb’: Sense of Localness in Neolocalism: Tourism Dynamics on Heimaey, Iceland
Authors: Röslmaier Michael , Ioannides Dimitri
Published: October 2023

Neolocal expressions where inhabitants promote distinguishing community characteristics through tourism have become increasingly popular in remote cold-water islands. Although scholars primarily discuss neolocalism in the context of microbreweries, evidence has emerged of tourism-neolocalism dynamics. Airbnb rentals, for instance, can be considered as neolocal playgrounds where inhabitants and tourists immerse themselves in and promote a destination’s localness. Through a qualitative case study, this paper examines how these traits play out on Heimaey, Iceland. It investigates whether distinct Airbnb hostings, ranging from locals cohabiting with visitors to more professionalised services exhibit divergent neolocal forms. Findings demonstrate that Airbnb delivers a form of neolocalism stemming from inhabitants’ living spaces whereby hosts construct localness either in the name of conservation or innovation. In this process, the boundaries between the local(isms), the global, and cosmopolitanism are blurred, thus complicating people’s sense of localness. Here, neolocalism becomes more than a mere commercial tool that automatically leads to sustainable outcomes. This study enriches our understanding of new intersections of modern tourism trends and their impact on a community’s sense of localness. Further research is needed to unravel the implications of these dynamics for community wellbeing from a community sustainability and resilience perspective.
A survey study toinvestigate food handler’sknowledge, attitudes andbehaviour towards foodsafety and food practicesin restaurants in Liverpool
Authors: Kingston Ben , Mitchell Graeme
Published: October 2023

Food establishments are on the rise in the United Kingdom, producing a widevariety of cuisine to cater for a variety of tastes in a global market. However, asignificant proportion of the population will experience a foodborne illness atsome point in their lives, and in 2018 alone there were estimated to be 2.4million food borne illness related cases in the UK [1]with a resulting 180 deathsper year. Whilst Local Authorities monitor and inspect these establishmentsperiodically, the importance of those who work within food business cannot beunderestimated. As such the aim of this research study was to explore foodhandlers’ knowledge, attitudes, and behaviour towards food safety and foodhandling practices in restaurants within Liverpool. Using both convenience andsnowball sampling, the research employed a quantitative online questionnaire togather data from the target population of food handlers. The responses from 52participants were then analysed using a combination of Microsoft Excel andSPSS version 28. The results of the study reveal that food handlers in Liverpoolfood businesses have a generally satisfactory level of food safety knowledge;their attitudes expressed demonstrated a strong positive approach and theyengage in safe behaviour. However, the results show some areas of concern:knowledge surrounding harmful pathogens was lacking; behaviour in relation tothe use of mobile phones in the kitchen and attitudes towards attending workwhilst unwell. Therefore whilst the overall knowledge, attitude and behaviours offood handlers appears acceptable that does not mean they do not pose risk tocustomers. Whilst all participants had received training, this did not alwaystranslate into improved food handling knowledge, attitudes or behaviours.Training, therefore, must be tailored to reflect the needs to the individual withthe understanding that knowledge, attitudes and behaviours are linked.

Introduction

Testin is a protein involved in cell mobility, adhesion and colony formation. In rats, testin presence has been reported in the testes, and its possible role in spermatogenesis has been suggested. Studies in humans also suggest a possible role of testin as a cancer suppressor protein. In the dog, which represents both an important pet species and a good animal model for studying biological and pathological testicular processes, the presence of testin has never been reported.

Material and Methods

In the present study, the expression of testin in foetal, prepubertal, adult and aged canine testes was investigated. Testes from 5 adult and 3 aged dogs, from 2 one-month-old puppies and from 2 foetuses miscarried at the end of pregnancy were immunohistochemically examined with a commercial antibody against testin.

Results

Testin was intensely expressed in Sertoli cells in every testis examined. Spermatids were also positive for testin in mature dogs and in the testicular areas of the aged ones which were not atrophic. Weak expression of testin was also detected in all testes examined.

Conclusion

The present study, the first demonstrating the presence of testin in canine testes, provides the basis for further dog–human comparative research and for studies on the role of this protein in canine physiology, reproduction and testicular pathologies.

Effectiveness of molecular fingerprints for exploring the chemical space of natural products
Authors: Boldini Davide , Ballabio Davide , Consonni Viviana , Todeschini Roberto , Grisoni Francesca , Sieber Stephan
Published: October 2023

Natural products are a diverse class of compounds with promising biological properties, such as high potency and excellent selectivity. However, they have different structural motifs than typical drug-like compounds, e.g., a wider range of molecular weight, multiple stereocenters and higher fraction of sp3-hybridized carbons. This makes the encoding of natural products via molecular fingerprints difficult, thus restricting their use in cheminformatics studies. To tackle this issue, we reinvestigated over 30 years of research to systematically evaluate which molecular fingerprint provides the best performance on the natural product chemical space. We considered 20 molecular fingerprints from four different sources, which we then benchmarked on over 100000 unique natural products from the COCONUT database. Our results show that despite their apparent comparability, different fingerprinting algorithms can provide fundamentally different views of the natural product chemical space, leading to substantial differences in pairwise similarity. Surprisingly, circular fingerprints, despite being the most popular molecular fingerprint class, were outperformed by path-based, substructure-based and string-based encodings for supervised classification modeling of natural products, highlighting the need to evaluate multiple fingerprinting algorithms for optimal performance and suggesting new areas of further research. Finally, we provide an open-source Python package for computing all the 20 molecular fingerprints considered in the study, as well as data and scripts necessary to reproduce the results, at https://github.com/dahvida/NP_Fingerprints.

Published: October 2023

Background: Ectoparasites are predominant parasitic infections among children. Head lice (Pediculus humanus capitis) are transmitted parasites, mainly among school-aged children. Although, head lice are not a chief health hazardor or a vector for disease, they are a public social problem. The transmitted infections by a parasitic bite, may reach the blood which causes health problems for children and affects their health.

Objective: To investigate the effects of infection with head lice on Immunoglobulin E (IgE), vitamin D3, Zinc, and blood parameters.

Patients and Methods: Samples including skin swapping and blood samples were collected from 300 children who were examined at AL-Batool Maternity Teaching Hospital (AL-BMTH) and some medical centers. Skin scraping and swapping were examined microscopically for detection of the parasite. Blood samples were analyzed for immunological and blood parameter estimation, during the period from 1st October 2021 to the end of May 2022. Samples were sent to the parasitology and hematology laboratories in AL-BMTH to identify the parasitic infections and their effects.

Results: The samples include 180 females and 120 males, 90 samples  of the 300 were epidemic with lice infection, 48.9% of them were at age 1-5 years, 35.6% were at age 6-10 and 15.6 % were at age 11-15,  91% of the infected children were females, while only 9 % of the infected children were males. The blood analysis indicated that the levels of vitamin D and the mineral Zinc, were lower in children infected with head lice compared to the control, while IgE was higher. RBC and Hb showed a lower level in infected children than in control, whereas WBC was at a high ratio in most patients.

Conclusion: Parasites cause many diseases in children in particular. They spread in rural and crowded places and affect the activity and vitality of children.

Published: October 2023

Background: A review of many kinds of literature has suggested the theory of infections to are a risk for atherosclerosis of the coronaries, many of medical researchers reported that Helicobacter pylori pathogenesis extends beyond the gastrointestinal system to be a risk factor for inflammatory-induced atherosclerosis including that of the coronary vessels.

Objective: To  detect a relationship between the seropositivity of Helicobacter pylori bacteria in the blood with the severity of coronary artery atherosclerosis.

Patients and Methods: A total of 125 patients were taken in this study including both sex male and female with different age groups all of them admitted to cardiac center hospital in Erbil City in Iraq. Patients were suspected to have coronary artery atherosclerosis based on symptoms and primary cardiac diagnostic tools, Angiography was performed to confirm or exclude coronary artery lesions by catheterization in the cath lab of the hospital. Blood samples were taken from patients including the patients’ group and control group and a C-reactive protein (CRP) test with Helicobacter pylori IgG antibody test was done for them by using an Enzyme-linked immunosorbent assay (ELIZA) apparatus. Coronary angiography Confirmed the presence of atherosclerosis and the severity of it according to the number of vessels and the degree of luminal stenosis.

Results: The results show that the most of patients with atherosclerosis (83.5%) a high level of C-reactive protein. Also, a positive significant correlation was detected between the Helicobacter pylori concentration and the number of narrowed vessels   based on the results of this study Helicobacter pylori.

Conclusion: According to the results Helicobacter pylori has a significant risk predictor for the severity of coronary atherosclerosis. However, evidence on this fact is not sufficient which further studies are needed.

Authors: Karim Hadaia Measar
Published: October 2023

Background: Although hematospermia is not common but considered an alarming symptom for patient and doctor. The cause of this worry is that it has been described as a dangerous symptom of prostate cancer by the patients and the health workers.

Objective: To classify the causes and outcome of hematospermia.

Patients and Methods: : This is a prospective study of patients newly diagnosed with hematospermia-diagnosed and treated in private clinic and hospital over a period of 4 years (2018-2022). Data collection and recording done related to demographic, symptomatology, clinical finding, investigations, treatment given and the outcome during 6 months of follow up.

Results: One hundred and six patients with hematospermia were seen in the private clinic and hospital. The mean age was 40 years (25-70). Thirty-six (33.9%) patients were diagnosed as prostatitis clinically or by positive seminal fluid culture. Only (4) patients had prostate carcinoma with only one new case and the other three were known cases of prostate cancer already on treatment. With (4) cases had thrombocytopenia and (2) cases with sickle cell anemia and (1) case each prostate cyst and severe hypertension and vesical stone.  (2) cases on anticoagulant therapy. And another (2) cases with history of epididymal surgery. There was no identifiable cause in the remaining 53 patients (50%).

Conclusion: the majority of patients presented with hematospermia were below 50 years and have benign etiology and most of them were self-limited and less than 1% of cases revealed new prostate cancer. So, we can confidently reassure a patient presented with hematospermia due to benign nature of the disease in the majority of patients, especially in young patients.

Authors: Hammadi Fahad , Saja , Ahmed Ameen Najiha
Published: October 2023

Background: End-stage renal disease is the final stage of chronic kidney disease in which irreversible deterioration in renal function occur and the body fails to maintain fluid and electrolyte balance, this need regular hemodialysis (HD) a process that removes accumulated solute from a patient with near-total renal function loss. Arteriovenous fistula (AVF) is the vascular access of choice for patients who require hemodialysis. AVF thrombosis is a major issue in hemodialysis  patients, which increase their morbidity and  lessen HD efficiency.

Objective: To assess plasma level of ADAMTS-13 in HD patients and its association with AVF thrombosis, and to correlate the plasma level of ADAMTS-13 with age, duration of dialysis, certain hematological parameters and estimated GFR.

Patients and Methods:This Cross_sectional study done on 60 patients  with ESRD on regular HD sessions, 20 healthy persons were included as a control . The patients subdivided into two subgroups with and without AVF thrombosis. Plasma samples were freezed until the test for the level of ADAMTS-13  was done.

Results: The plasma ADAMTS-13 level was significantly lower in HD patients compared to control group (P < 0.001), and was a significantly lower in  patients with a history of AVF thrombosis than HD patients without a history of AVF thrombosis.  HD patients with AVF thrombosis had significantly lower eGFR compared to patients without a history of AVF thrombosis. There was a positive correlation of plasma ADAMTS-13 level with the mean of eGFR , platelet count and negative correlation with MPV.

Conclusion: Significant differences  between HD patients and control regarding eGFR and hematological parameters . Plasma ADAMTS-13 level was significantly lower in patients compared to controls and significantly lower in patients group with AVF thrombosis than HD group without thrombosis.
IL-17 and IL-10 as potential biomarkers for diagnosing periodontitis patients: A Review
Authors: Abdulsalam Mohammed , Maha , Fadhil Abbas Raghad
Published: October 2023

Background:Evaluation methods for periodontal disorders are continually being refined to yield more precise, reliable, and time-efficient findings. Radiographic reports and clinical assessments of periodontal tissues, which served as the basis for earlier trends, were used to identify disorders affecting the tooth-supporting structures. As traditional approaches have become more apparent gradually over time, new methods emerged, some of which have been empirically validated. One example is the detection and measurement of biomarkers in bodily fluids. One of the most pressing issues in periodontal field nowadays is the search for an idealized periodontal diagnostic/prognostic biomarker that can both identify diseased areas and track the therapeutic success of periodontal treatment. Both IL-17 and IL-10 have shown connection to periodontitis that could encourage using them as diagnostic tools.

Objective: To provide a review of the role and association of the above biomarkers to periodontitis.

Patients and Methods: A systematic research of Google scholar, Scopus, PubMed Central, research gate was conducted using keywords such as diagnosis, periodontitis, IL-17, IL-10, biomarkers, Saliva and gingival crevicular fluid (GCF).

Results: out of 58 records which resulted from the initial search only 14 were included which used roles, associations, and diagnosis as their outcomes.

Conclusion: Evidence from the selected records suggests that the above stated biomarkers might be able to discriminate periodontitis from health, monitoring disease progression and post treatment outcome, but actual clinical application needs much further research.

Background: Both Viruses are the leading cause of acute gastroenteritis in infants and young children and are considered an important cause of mortality worldwide.   

Objective: To estimate the rate of human bocavirus and rotavirus co-infection in children with acute gastroenteritis and determine any association with different risk factors.

Patients and Methods: Stool samples were collected from one hundred children suffering from acute gastroenteritis at the Central Teaching Hospital of Pediatrics, Baghdad, Iraq, for the period from December 2021 to April 2022. Samples were stored at -20 °C until they were utilized by PCR and ELISA to identify the human bocavirus (HBoV) DNA and rotavirus antigen (RV-Ag), respectively.

Results: This cross-sectional study showed that HBoV DNA was detected in 10 out of 100 samples (10%), while RV-Ag was detected in 22 out of 93 samples (23.66%), and the co-infection rate was 100% (All cases positive for HBoV were also positive for RV). None of the studied demographic data and risk factors showed a significant association with HBoV and/or rotavirus infection (P>0.05).

Conclusion: Most NICU deaths resulted from prematurity and respiratory distress syndrome. Enhancing healthcare personnel skills, standardizing protocols, and evidence-based practices for preterm and respiratory distress syndrome management can help reduce neonatal mortality rates in Iraq.

Os organismos da macrofauna epígea são componentes da biota do solo, com diversas funções, entre elas, a fragmentação dos resíduos vegetais, a predação e a estruturação do solo. O objetivo deste trabalho foi analisar a macrofauna epígea em área de capim-elefante (Pennisetum purpureum Schum.). A pesquisa foi realizada no período de janeiro a fevereiro de 2022, no Parque de Exposições Dirceu Arcoverde, localizado na cidade de Teresina, Piauí. Foram selecionadas duas áreas, uma com capim-elefante e outra área de mata nativa secundária. Em cada área foram demarcados cinco pontos em um transecto, totalizando dez pontos amostrais. Para as coletas dos organismos utilizamos armadilhas de queda do tipo Provid, que permaneceram nas duas áreas por 96 horas. A temperatura da superfície do solo foi aferida com termômetro digital e o conteúdo de água do solo determinou-se pelo método gravimétrico, na camada de 0-10 cm do solo. Os organismos foram identificados em nível de classe e ordem. Para avaliação da diversidade da macrofauna foram utilizados os índices de diversidade de Shannon-Wiener, e parâmetros descritivos para a temperatura do solo e conteúdo de água do solo. A correlação da riqueza e abundância da macrofauna epígea com as demais variáveis do ambiente foi analisada através de matriz de correlação. Foram coletados 847 espécimes, com diversidade de dezeseis Ordens. A Ordem Hymenoptera representou 49,94% seguido pela Araneae 16,53% e Opiliones 10,74% dos indivíduos capturados. A área de mata nativa apresentou um maior indice de diversidade em relação a área de capim-elefante. Portanto, o cultivo da forrageira propiciou a presença de importantes grupos faunístico para o sistema solo-planta desempenhando riqueza no serviços ambientais.
