Authors: Kabir Muhammad Humayun , Khairuzzaman Mohammad , Ahmed Tanvir , Hossain Muhammad
Published: July 2024

Objective: To compare prospectively the outcome of non-closure of buccal mucosal graft harvest site in comparison to its’ primary closure.
Methods: Patients who underwent BMG harvest for urethroplasty were randomized into 2 groups; in group 1 donor site was closed and in group 2 it was left open. Pain at BMG harvest site was the primary variable. Postoperative resumption to regular diet and difficulty in mouth opening were 2 other variables. After buccal mucosal graft harvesting, donor area was either closed (group 1) or left open and allowed to heal by second intention. In the postoperative period, visual analog score was to evaluate pain at donor area. Self made questionnaires were used to assess limitation to mouth opening andthe time to resumption of liquid and solid diet.
Results: Thirty two patients were studied, 16 in each group from December 2012 to June 2014. Mean age among the two groups were almost same(closure group, 42.37 years Vs 41.26 years in nonclosure group). Mean stricture length was 4.75 cm in closure group and 7.53 cm in non -closure group. In closure group, BMG was harvested from single cheek in most of the patients but in non closure group, graft was harvested from both cheeks and also from lower lips in few patients. Mean post operative pain score was 5.06 and 3.68 at day 1 in group 1 and group 2, respectively (P < 0.008) but as the days progressed, pain score in both groups became comparable. Return to oral intake in terms of liquid and solid diet was comparable between the groups. Difficulty with mouth opening was maximal during the first week with no difference among the two groups.
Conclusion: Pain appears to be worse in the immediate post operative period with suturing of the harvest site. There is no difference in long term morbidity whether the graft site is closed or left open. It may be best to leave buccal mucosa harvest sites unsutured.

Testicular Neoplasm With Inguinal Lymphnode Metastasis - an Unusual Presentation
Authors: Paul Tapash Kumar , Chowdhury Arman Reza , Lodi Russel Ahmed Khan , Ali Shayeda , Basunia Mohammad Arman Zahed , Rouf Hasan Md Abdur
Published: July 2024

Testicular neoplasm and infertility are two common complications of cryptorchidism. Early surgical treatment of undescended testis i.e. between 3 to 12 months of age appears to lower the risk of complications. If done later, the risk of testicular cancer cannot be eliminated. Another important thing is that for diagnosing testicular neoplasm open biopsy or core biopsy is usually not done before operation. If essential, it is done through inguinal route during surgery (frozen section biopsy), and is never through scrotal route until and otherwise it has already invaded the scrotal skin causing ulceration. In that case there may be chance of spreading malignancy into inguinal lymph nodes.

The Levy System in East Bengal and its Impact on the Peasantry (1949-1967)
Authors: Karim S M Rezaul Karim
Published: July 2024

The peasants of Bengal have been living through exploitation since ancient times. The intensity of exploitation of farmers increased manifold from the ancient period to the colonial period. The main reason for this was that on the one hand, the land tax or rent paid to the state during the pre-British period was increased many times and on the other hand, apart from rent, many kinds of abwabs were levied on the peasants. During the British era, the farmers thought that this exploitation and deprivation would end if the country became independent. But after the departure of the British in 1947, in the independent state of Pakistan, the farmers of East Bengal were subjected to exploitation and oppression as in the colonial period. During the Pakistan period, like the British period, the taxes and abwabs paid to the state were increased. Moreover, the levy system, a unique type of agricultural land tax that was assessed based on the total production of the farmer's total land, was introduced by the Muslim League government. As a result, the level of exploitation and oppression of the farmers of East Bengal increased manifold during the Pakistan period. Based on primary and secondary sources, this paper attempts to provide a comprehensive understanding of the introduction of the levy system and investigate its impact on the farmers. The paper will also shed light on  the reactions of politicians and peasants to this newly introduced levy system in East Bengal during the Pakistan period.

We demonstrate the operation of a virtual keyboard utilizing electromyography signals derived from finger movements. Initially, we identify human arm surfaces corresponding to specific finger motions, where EMG sensors are subsequently placed. The raw EMG signals obtained from our setup undergo filtration using a custom-made electric circuit. A LabVIEW program is employed to measure and manage these EMG signals. Following the conversion of analog signals to digital format, the data is inputted to an Arduino board, which then displays the corresponding letters from the virtual keyboard onto a computer monitor. The success of this demonstration is contingent upon a training session adhering to the established protocol.

Masalah Value Trace untuk pembacaan koding dalam Bahasa Pemrograman C
Authors: Risyani Yeni , Japit Susi , Selamat Tanda
Published: July 2024

Banyak universitas di seluruh dunia mengajarkan pemrograman C sebagai bahasa komputer pengantar. Oleh karena itu, sangat penting bagi siswa pemula untuk terlibat dalam pembacaan ekstensif kode sumber C sederhana untuk memahami prinsip-prinsip pemrograman. Namun, ada kekurangan alat yang dirancang dengan baik untuk mendukung pembelajaran membaca kode secara mandiri di rumah. Sebelumnya, kami telah memperkenalkan konsep value trace problem (VTP) untuk pemrograman Java, di mana setiap contoh VTP terdiri dari kode sumber, beberapa pertanyaan, dan jawaban yang benar. (Klabnik & Nichols, 2023) Pertanyaan-pertanyaan ini menanyakan tentang nilai variabel kritis atau pesan keluaran dalam kode sumber, dengan respons siswa yang langsung divalidasi melalui pencocokan string untuk belajar mandiri. Dalam makalah ini, kami memperkenalkan VTP untuk belajar mandiri membaca kode dalam pemrograman C. Kami membuat 42 contoh VTP berdasarkan kode sumber C langsung yang mencakup konsep tata bahasa dasar dan struktur data fundamental serta algoritma yang ditemukan dalam buku teks dan sumber daya online. Selain itu, untuk contoh kasus yang menantang yang melibatkan pointer dan algoritme yang rumit, kami menyertakan petunjuk, pertanyaan pilihan ganda, dan referensi untuk meningkatkan akurasi solusi. Untuk menilai pendekatan kami, kami meminta 49 mahasiswa S1 dari Jepang, Cina, dan Myanmar untuk menyelesaikan contoh-contoh ini secara mandiri di rumah. Tingkat akurasi rata-rata mereka adalah 94,29%, dengan fitur-fitur pendukung kami yang meningkatkan akurasi sebesar 33,26% pada kasus-kasus yang sulit. Dengan demikian, proposal kami secara efektif mendorong pembelajaran mandiri dalam pemrograman C di kalangan siswa pemula. (Aho et al., 2023)

Published: July 2024

Several literatures provide indications on the results of their research that martial arts activities can have a positive effect on the development of adolescents. However, martial arts activities that have been running still do not reveal programs that lead to positive youth development. Apart from that, there is still uncertainty regarding the martial arts training program which is still focused solely on achieving achievements. This study reveals the contribution or role of martial arts activities by providing an overview and explaining the results of the latest research on martial arts activities for positive adolescent development. Literature data collection techniques were taken using systematic computer searches consisting of several journal articles and dissertations, as well as manual data search results. Data collection was carried out for two months in January and February 2024. Several articles were eliminated which were then focused on the 17 articles used in this study. The results show that martial arts activities have had a major impact on positive adolescent development in recent years. The main topics in several research results in general are about prosocial behavior, antisocial behavior, aggression and resilience. There is strong agreement among researchers about the potential of martial arts activities for positive adolescent development. In addition, the discussion in several studies shows clearly that the main influence in martial arts activities is closely related to how the trainers make a strong contribution in providing understanding and also the teaching style used in martial arts activities

A presente pesquisa teve por finalidade avaliar a efetividade da gestão do Programa Nacional de Alimentação Escolar do município de Belém, Estado do Pará, no ano de 2018. O Conselho de Alimentação Escolar e a Rede de Controle da Gestão Pública no Estado do Pará, constituída por diversos órgãos de controle, realizaram pesquisa transversal, em ação simultânea de único dia, em 10 escolas municipais, com aplicação de instrumento estruturado em escala sensorial hedônica que avaliava três aspectos da alimentação escolar: qualidade, quantidade e frequência de distribuição, cujos dados foram avaliados por estatística descritiva. A média dos resultados expressos por estudantes do Ensino Fundamental I e II e pré-escolares da Educação Infantil revelaram que a aceitabilidade da qualidade da alimentação na capital paraense expressou 36,1% e a aceitação da quantidade das porções distribuída aos estudantes foi de 42,3%, valores acentuadamente menores que o índice oficial estabelecido para o programa (85%); a regularidade da oferta (89,8%), indicando que os alunos consideram que há poucas falhas na frequência de distribuição da alimentação escolar. Os baixos índices indicam a pouca efetividade do programa e a necessidade de acontecerem avaliações periódicas para monitorar e instar para sua adequada execução.
Combining reproductive endocrinology and ROC analysis to identify changes with sex, age, and pregnancy status in botos Inia geoffrensis

Published: July 2024

Reproductive hormone profiles were described against physical characteristics during growth and development in male and female botos (Amazon River dolphins Inia geoffrensis) and during pregnancy. We determined hormone concentrations in 226 wild botos located in Mamirauá Reserve, Amazonas State, Brazil, as a part of the long-term population monitoring program known as Projeto Boto. Additionally, we applied receiver operator characteristic (ROC) analysis to compare diagnostic probabilities of using ultrasound, hormones, or combinations of these to detect pregnancy. Based on single-point analysis of serum testosterone (T), males with <2.5 ng ml-1 T and a mean 163 cm total body length were classified as immature, 2.5 to <4.9 ng ml-1 T and 183 cm as pubescent, and >5 ng ml-1 T and 227 cm as adult botos. For females, only progesterone (P4), T, relaxin (Rlx), and the combination of P4 × T2 were significantly different between non-pregnant and pregnant females, but androstenedione (A4) and the P4:T ratio were not. ROC analysis indicated that ultrasound and P4 × T2 were considered excellent as pregnancy diagnostic tests, and P4, T, and Rlx were classified as good predictors. Results indicated that negative and positive predictive probabilities from each diagnostic test could be used to accurately predict a pregnancy and calf loss rate of 13% for this population. Application of these methods for evaluating wild population reproductive success from a single serum sample can now be used for health evaluations of wild populations of boto and provide timely information for the development or evaluation of any conservation initiatives.
DNA analysis of scats reveals spatial and temporal structure in the diversity of harbour seal diet from local haulouts to oceanographic bioregions
Authors: Trzcinski MK , Majewski S , Nordstrom CA , Schulze AD , Miller KM , Tucker S
Published: July 2024

Predation shapes ecosystems, and quantifying the impacts of predation on the distribution and abundance of prey requires substantial effort at appropriate spatial and temporal scales for diet estimation of predators. Here, we present diet estimates of a marine predator (harbour seal Phoca vitulina richardsi) from scat collections (n = 3420) sampled at multiple haulout sites (n = 64) in the Strait of Georgia and other coastal regions around Vancouver Island, British Columbia, Canada, between 2015 and 2019. DNA metabarcoding and hard part analysis were used to identify the proportion and sizes of prey species consumed, respectively. We found that harbour seals consumed 62 primary prey species. Diversity in the diet was highly affected by the number of samples collected and varied at small spatial scales (haulout sites) as well as among broad bioregions. Three to 5 species dominated the diet depending on location, season, and year, including Pacific hake Merluccius productus, Pacific herring Clupea pallasii, and walleye pollock Gadus chalcogrammus. Within the Strait of Georgia, both male and female harbour seals consumed more hake and walleye pollock in areas and seasons in which they were more abundant. Harbour seals consumed a wide size range of prey that also varied by species, season, and region. These results indicate that harbour seal foraging is influenced by both the local abundance and composition of prey. Attempts to model the impact of predation on species of concern risk bias in their estimates and underrepresenting uncertainty if spatial and temporal variation in the diet is not accounted for.

Published: July 2024

The aim of the paper was to evaluate the price development of electrical energy and inflation as a commodity in the course of the past 10 years. The production of electrical energy decreased from 83.7 TWh in 2010 to 70.6 TWh in 2020 in the Czech Republic in accordance with the results achieved by using the methods of descriptive statistics, time series, correlation analysis and regression analysis. The consumption of energy slightly increased. The proportion of production to consumption declined and consumption was higher than production in 2020. The prices of electricity reveal oscillations influenced by the conflict in the Ukraine. The use of the sources of energy changed, however, without specific trends. The dependence of prices on inflation is considerable and direct. Energy policy ought to deal with the dependence on import and support the domestic production of energy.

Smartphones have become part of our everyday life. But what to do with our old device when we want a new one? Everyone will deal with this question differently and this paper aims to present the most used approaches and the reasoning behind them as well as pros and cons of each approach. The study is done by using an analysis of research conducted by the Czech Statistical Office on the topic of sustainability in ICT on respondents over the age of 16 in 4.5 million households. The results can help smartphone companies understand how their products are disposed of once replaced by another model and help us understand the effects and potential risks this might have on our environment. The targeted research area is the Czech Republic. By comparing age categories, we get the results that the most common option is to keep the old phone at home if the new one breaks, this option was chosen by 46,9 % of respondents. Other favorite options are sending it for recycling which chose 17,5 % or selling it with the results being 14,9 %.
PRICE DYNAMICS OF FOSSIL FUEL COMMODITIES IN THE PERIOD 2014 - 2024
Authors: KAŠPAROVÁ SANDRA , NIKITENKO YELYZAVETA
Published: July 2024

Over the last decade, the dependence on fossil fuels and their prices has been increasingly discussed. This paper aimed to assess the development of fossil fuel prices and their relationship to GDP in the Czech Republic. To achieve this objective, a VAR model and Granger causality test were used. All fossil fuel prices peaked in 2022. The causal relationship with GDP in the Czech Republic was confirmed for natural gas and coal prices. On the other hand, the causal relationship between oil and GDP in the Czech Republic was not confirmed during the period under study. Weak correlations were found with the Covid-19 pandemic, inflation, and unemployment in the EU. The only exception is the correlation between coal and inflation in the EU, which was moderately strong. A limitation of the paper is the length of the period studied, with data collection taking place only once a month.

Allergy and its manifestations were first appreciated in the 1870 s. Today, the mechanism by which specific substances elicit allergic reactions remains poorly understood. This is problematic from a healthcare perspective because the prevalence of allergic disease and its societal costs are substantial. Regarding mechanistic understanding of allergy, a new proposal, The Acari Hypothesis, has been forwarded. The Hypothesis, borne from consideration of alpha-gal syndrome, postulates that acarians, i.e., mites and ticks, are operative agents of allergy. By way of their pathogenic payloads and salivary pattern recognition receptor(s), acarians potentiate in human hosts the generation of IgE against acarian dietary elements. Those elements account for most, if not all, known human allergens. Inasmuch as acarian—human interactions occur on human epithelial surfaces, it is to be expected factors that influence the presence and/or operation of acarians on those surfaces influence the expression of allergic diseases. In this report, it is proposed that two adaptations of catarrhine primates, i.e., Old World monkeys, apes and humans, evolved to deter acarian species: firstly, the expansion of eccrine glands across the entirety of body surface area, and, secondly, the secretion of sweat by those glands. Contemporary hygienic practices that reduce and/or disrupt the operation of eccrine glands are likely responsible for the increase in allergic disease seen today.

Objective

Parkinson’s disease (PD) is the second most common neurodegenerative disease in the world, and type 2 diabetes (T2DM) and PD are influenced by common genetic and environmental factors. Mitochondrial dysfunction and inflammation are common pathogenic mechanisms of both diseases. However, the close association between PD and T2DM and the specific relationship between them are not yet clear. This study aimed to reveal the specific connection between the two diseases by establishing a mouse model of comorbid PD and T2DM, as well as a Bv2 cell model.

Methods

C57BL/6 mouse were used to construct a model of PD with T2DM using streptozotocin and rotenone, while Bv2 cells were used to simulate the microenvironment of PD and T2DM using rotenone and palmitate. Behavioral tests were conducted to assess any differences in motor and cognitive functions in mouse. Immunohistochemistry was used to analyze the number of dopaminergic neurons in the substantia nigra region of mouse. Western blotting was used to detect the expression levels of TH, P-NFκB, NFκB, Cyclic GMP-AMP synthase (cGAS), and Stimulator of interferon genes (STING) proteins in the substantia nigra region of mouse and Bv2 cells. qRT-PCR was used to analyze the expression levels of IL1β, IL6, and TNF-α. Seahorse technology was used to assess mitochondrial function in Bv2 cells.

Results:

T2DM exacerbated the motor and cognitive symptoms in mouse with PD. This effect may be mediated by disrupting mitochondrial function in microglial cells, leading to damaged mtDNA leakage into the cytoplasm, subsequently activating the cGAS-STING pathway and downstream P-NFκB/NFκB proteins, triggering an inflammatory response in microglial cells. Microglial cells release inflammatory factors such as IL1β, IL6, and TNF-α, exacerbating neuronal damage caused by PD.

Conclusion

Our study results suggest that T2DM may exacerbate the progression of PD by damaging mitochondrial function, and activating microglial cell inflammation. The detrimental effects on Parkinson’s disease may be achieved through the activating of the cGAS-STING protein pathway.

The current work aims to extend our understanding of the relationship between academic performance and burnout. Using longitudinal data collected from 521 students enrolled in a Singapore-based university from their freshmen year up to the end of year two, we examined the temporal order of the GPA-burnout relation to determine if there is a reciprocal relation between students’ burnout and academic performance. Grit, grit-passion, grit-perseverance, self-efficacy, and resilience were tested as moderating factors that were thought to potentially exacerbate, or protect against, the negative effects between GPA and burnout. Employing a panel analysis by means of SEM revealed that the relationship between GPA and burnout in our data is one where higher GPA contributes to worse burnout. Of all the moderating factors, only grit-passion was found to moderate the relationship between GPA and burnout, indicating that this relationship also depended on whether one has high or low grit-passion. In practice, our findings imply that high-achieving students are at risk of experiencing burnout due to excessive pressure and constant striving for better performance, but cultivating passion and enjoyment for academic activities can serve as a protective factor against burnout.

Introduction

Lung carcinoids (LCs) are a type of neuroendocrine tumor (NET) that originate in the bronchopulmonary tract. LCs account for 20–25% of all NETs and approximately 1–2% of lung cancers. Given the highly vascularized nature of NETs and their tendency to overexpress vascular growth factor receptors (VEGFR), inhibiting angiogenesis appears as a potential therapeutic target in slowing down tumor growth and spread. This study evaluated the long-term antitumor activity and related mechanisms of axitinib (AXI), a VEGFR-targeting drug, in LC cell lines.

Methods

Three LC cell lines (NCI-H727, UMC-11 and NCI-H835) were incubated with their respective EC50 AXI concentrations for 6 days. At the end of the incubation, FACS experiments and Western blot analyses were performed to examine changes in the cell cycle and the activation of apoptosis. Microscopy analyses were added to describe the mechanisms of senescence and mitotic catastrophe when present.

Results

The primary effect of AXI on LC cell lines is to arrest tumor growth through an indirect DNA damage. Notably, AXI triggers this response in diverse manners among the cell lines, such as inducing senescence or mitotic catastrophe. The drug seems to lose its efficacy when the DNA damage is mitigated, as observed in NCI-H835 cells.

Conclusion

The ability of AXI to affect cell viability and proliferation in LC tumor cells highlights its potential as a therapeutic agent. The role of DNA damage and the consequent activation of senescence seem to be a prerequisite for AXI to exert its function.
