SERUM VITAMIN E, C AND A LEVEL IN LUNG CANCER: A CASE CONTROL STUDY

Lung cancer is a leading cause of cancer death worldwide, causing approximately 1.2 million deaths per year. Lung cancer is prevalent in smokers. It is documented that smoking induces oxidative stress, which is thought to be associated with the aetiology of carcinogenesis. A case control cross sectional study was conducted on sixty lung cancer patients and sixty smokers as cohort control. Serum levels of antioxidant vitamin E, C and A among the case and control subjects were estimated. It was observed that vitamin E value among the study population did not alter (15.67±3.67μmol/L vs. 14.66±3.88μmol/L). It was within normal range. Conversely, there was significantly high serum concentrations of vitamin C and A in the lung cancer patients as compared to those in the smoker controls (48.26±6.81versus 16.65±4.46μmol/L; 2.76±0.32 versus 1.60±0.35μmol/L respectively)

Reliability of the tools used to examine psychological distress, fear of COVID-19 and coping amongst migrants and non-migrants in Australia

Study tools examining psychological distress, fear of COVID-19 and coping amongst migrants and non-migrants in Australia are very limited. The aim of this research was to assess the psychometric properties and correlation of the English version of Kessler Psychological Distress Scale (K-10), Fear of COVID-19 Scale (FCSV-19S), and Brief Resilient Coping Scale (BRCS) tools during the COVID-19 pandemic situation in Australia. Data from a cross-sectional survey (n = 516) were utilized to examine reliability; 299 (57.9%) were migrants. High internal consistency, as evidenced by Cronbach’s alpha, was found for the K-10 (0.92), FCV-19S (0.87) and BRCS (0.66) tools. The corresponding values for migrants and non-migrants were (0.92, 0.87, 0.67) and (0.92, 0.86, 0.63), respectively. Item-total correlations ranged 0.57-0.78 for K-10, 0.62–0.69 for FCV-19S, and 0.39–0.50 for BRCS tools. EFA retained a single factor for each tool with adequate factor loadings. The scoring of K-10 was significantly predicted by the scoring of FCV-19S (r = 0.284, P < 0.001) and BRCS tool (r = 0.132, P < 0.01). Therefore, these tools can be used reliably amongst both migrant and non-migrant population in Australia. © 2021 John Wiley & Sons Australia, Ltd. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Muhammad Aziz Rahman and Wendy Cross" is provided in this record*

Islam, Alcohol, and Identity: Towards a Critical Muslim Studies Approach

Framed in a critical Muslim studies approach, this article offers a new understanding of the Ḥanafī position on alcohol, following major public debates on the question of alcohol sparked by prominent members of Al-Azhar University (Egypt) in 2012. Close textual analysis of a range of primary sources in Arabic and Urdu are foundational to the article, as are the categorisation and contextualisation of Ḥanafī discourse. This is all but a starting point, however, for an argument that constitutes a radical break from conventional Islamic studies, seen as "normal science," in its critique of hegemonic discourses which have essentialised Islam on the basis of specific ontic manifestations, such as the prohibition of alcohol

Design of LMS algorithm for noise canceller based on FPGA

This paper presents the design of an adapting filtering method to remove the noise in the biomedical signal records. The major concern about analyze the presence of various artifacts in ECG records and modular artifacts in EEG records caused due to various noise factors. Here, we have proposed a design based on LMS (Least Mean Square) algorithm to remove the artifacts from biomedical signal using Verilog HDL based on been mapped on  commercially available FPGAs (Field Programmable Gate Arrays). In this design the LMS algorithm used as a noise canceller and the reference signal was adaptively filtered and subtracted from primary signal to obtain the estimated biomedical signal. The original biomedical signal can be reconstructed by passing the digital bit stream through a low pass filter. This design is suitable for its low power biomedical instrument design and it reduces the whole system cost. Keywords: LMS algorithm, noise canceller, Verilog HDL, artifacts, biomedical signal, Low power application

Caesarean delivery and its association with educational attainment, wealth index, and place of residence in Sub-Saharan Africa : a meta-analysis

Caesarean delivery (C-section) has been increasing worldwide; however, many women from developing countries in Sub-Saharan Africa are deprived of these lifesaving services. This study aimed to explore the impact of certain socioeconomic factors, including respondent’s education, husband’s education, place of residence, and wealth index, on C-section delivery for women in Sub-Saharan Africa. We used pooled data from 36 demographic and health surveys (DHS) in Sub-Saharan Africa. Married women aged 15–49 years who have at least one child in the last five years were considered in this survey. After inclusion and excluding criteria, 234,660 participants were eligible for final analysis. Binary logistic regression was executed to determine the effects of selected socioeconomic factors. The countries were assembled into four sub-regions (Southern Africa, West Africa, East Africa, and Central Africa), and a meta-analysis was conducted. We performed random-effects model estimation for meta-analysis to assess the overall effects and consistency between covariates and utilization of C-section delivery as substantial heterogeneity was identified (I2 > 50%). Furthermore, the meta-regression was carried out to explain the additional amount of heterogeneity by country levels. We performed a sensitivity analysis to examine the effects of outliers in this study. Findings suggest that less than 15% of women in many Sub-Saharan African countries had C-section delivery. Maternal education (OR 4.12; CI 3.75, 4.51), wealth index (OR 2.05; CI 1.94, 2.17), paternal education (OR 1.71; CI 1.57, 1.86), and place of residence (OR 1.51; CI 1.44, 1.58) were significantly associated with the utilization of C-section delivery. These results were also consistent in sub-regional meta-analyses. The meta-regression suggests that the total percentage of births attended by skilled health staff (TPBASHS) has a significant inverse association with C-section utilization regarding educational attainment (respondent & husband), place of residence, and wealth index. The data structure was restricted to define the distinction between elective and emergency c-sections. It is essential to provide an appropriate lifesaving mechanism, such as C-section delivery opportunities, through proper facilities for rural, uneducated, impoverished Sub-Saharan African women to minimize both maternal and infant mortality

EFFECT OF YARN COUNT & STITCH LENGTH ON SHRINKAGE, GSM AND SPIRALITY OF SINGLE JERSY COTTON KNIT FABRIC

Single jersey cotton weft knitted fabrics tend to undergo a certain dimensional changes due to different yarn parameters and knitting parameters. The investigation was carried out to compare the effect of different yarn counts &amp; stitch lengths on the spirality, GSM and shrinkage of knitted fabric. In this study the experimental results show that when yarn count is fixed, the increment of stitch length results decrement of spirality, increment of shrinkage and decrement of GSM. On the contrary, when stitch length is fixed, the increment of yarn count results increment of spirality, decrement of shrinkage and decrement of GSM. Some exceptions were also experienced

Comparison of outcome between suture and suture-less surgery following pterygium excision and conjunctival autograft

Background: A pterygium, known as surfer's eye, is a raised, wedge-shaped growth of the conjunctiva that extends onto the cornea, the outer layer of the eye. Aim was to compare the safety, efficacy and outcome of suture less technique with suture of conjunctival autograft in the management of pterygium. Methods: This study was carried out in the department of ophthalmology, Sir Salimullah medical college and Mitford hospital, Dhaka. Study period was July 2019 to June 2020. Subjects for this study were divided into two groups, forty patients were enrolled in each group of the study population. Group I (control) comprised the subjects in whom suture was used following pterygium excision and conjunctival autograft and group II (experimental) comprised the subjects in whom no suture was used following pterygium excision and conjunctival autograft. Results: In group I, 20% were 20-29 years old, 30% were 30-39, 27.5% were 40-49, and 22.5% were over 50, with 77.5% being male and 22.5% female. In group II, 22.5% were 20-29 years old, 27.5% were 30-39, 30% were 40-49, and 20% were over 50, with 72.5% being male and 27.5% female. The most common symptom was "foreign body sensation" in both groups. In group I, 5% experienced partial graft dehiscence, 2.5% a conjunctival cyst, 10% hyperemia, and 17.5% visual improvement. In group II, 2.5% had partial graft dehiscence, 2.5% hyperemia, and 22.5% visual improvement. Neither group had graft retraction or recurrence. Conclusions: Postoperative presentation like hyperemia was significantly less in experimental group. Incidence of post-operative complications like graft dehiscence and conjunctival cyst were comparatively less frequent in suture less technique. Thus, suture less technique following pterygium excision and conjunctival autograft is a safer and less complicated than sutured technique
