Impact of Aging on Cranial Anatomy and Neurological Function
Authors: D Patel
Published: May 2024

As we age, our brains and cranial anatomy undergo significant changes that can profoundly affect our cognitive abilities and overall neurological function. This paper focuses onto the intricate interplay between aging, cranial anatomy, and neurological function, aiming to shed light on the complexities of brain aging and age-related neurological disorders. Through a comprehensive review of literature, it was found that there were age-related alterations in cranial anatomy, including changes in bone density, cranial shape, closure of sutures and fontanelles, as well as modifications in cranial blood vessels, cerebrospinal fluid dynamics, and circulation. Furthermore, the neurological consequences of aging, such as brain volume loss, ventricular enlargement, gray and white matter changes, neurotransmitter alterations, and synaptic dysfunction. The paper also discusses the clinical implications and challenges in diagnosing age-related neurological conditions, emphasizing the importance of interdisciplinary collaboration and advanced diagnostic techniques. Looking ahead, we highlight future research directions and opportunities, including advancements in neuroimaging techniques and the identification of therapeutic targets, to improve our understanding and management of age-related neurological changes. By addressing these challenges and embracing interdisciplinary approaches, we can pave the way for transformative advancements in aging research and enhance the quality of life for older adults worldwide
The Effects of Cognitive-Enhancing Activities in Senior Canine Patients
Authors: Fanucchi* Leticia
Published: May 2024

Aging process in dogs seem to be like aging in people. Human Alzheimer’s is a neurodegenerative condition very similar to the disorder in dogs, Canine Cognitive Dysfunction (CCD). CCD affects several areas of the brain, mainly ones responsible for regulating locomotion, problem-solving, navigation, and long-term memory. The onset of the disease occurs when neurotoxins are released into the brain. The presence of these toxins is manifested through symptoms including restlessness or lack of movement, disorientation, decreased ability to recognize family members, changes in patterns of interaction, sleep pattern alterations, and loss of house training. Treatment for this disorder is multimodal, including behavioral modification intended to stimulate the brain. In the present study, the canine cognition program, Dognition® was tested for its possibility to aid as a behavioral modification treatment plan to ameliorate symptoms of CCD assessed by a validated scale. We found that after the Dognition® activities, over half of the participants in the trial improved their scores for memory and communication. Additionally, before and after treatment, we found that that over half of the participants also improved their cognition scores. Implementation of diagnostic methods and behavioral modification programs is necessary to recognize and treat CCD in dogs.
Lexical Ideological Manipulations in Translation: George Orwell’s Animal Farm in Arabic
Authors:   , Alhazmi Bashaier A.
Published: May 2024

Investigating ideological manipulations is a continuing concern within the field of translation study. Owing to the fact that George Orwell’s novel Animal Farm has been growing in popularity among Arab readers since the advent of the so-called Arab Spring, this project aims to explore the ideological manipulations and interventions in the translations of Orwell’s novel Animal Farm into Arabic in the context of different political periods. It aims to determine the extent to which political conflicts in the target culture affect the translator’s lexical choices. Moreover, it explores the translators’ personal ideological manipulations in the target texts (TTs). Also, it aims to identify the strategies adopted by translators that led to ideological manipulations. The study uses three translations of Animal Farm into Arabic by three different translators and publishers. The translators and publishers are from Egypt, which was one of the countries that was affected by events of the Arab Spring. One translation was published in 2008, slightly before the advent of the Arab spring and the other two translations were published several years before that in 1997 and 1951. Through adopting the framework of Critical Discourse Analysis, the study aims to investigate at a lexical level the ideological shifts that occurred in the translations and how these shifts resulted in a manipulation of the target text. It goes further to investigate how these shifts are related to the political context of the target culture and of the translators. Lastly, it will explore the strategies used by translators that resulted in ideological manipulation. Far too little attention has been paid to investigating ideology in the translation of political novels into Arabic. In most cases, recent investigators have examined the ideology in political speeches and discourses. This study will contribute to other studies concerned with ideology in translating political novels.
Controlling the Public and Animal Health Threat from Campylobacter Infection in Broiler Chickens by Improving Gut Health and Reducing Inflammation
Authors:   , Hillier Amy
Published: May 2024

Campylobacter is a Gram-negative bacterium that causes disease in both humans and avian species. Poultry products present a major public health risk due to high levels of Campylobacter contamination which is a major cause of human bacterial gastroenteritis. Chickens are a primary reservoir for Campylobacter and there are no effective measures in place to inhibit flock colonisation and the extraintestinal spread of pathogenic strains. A large degree of variation is observed within the two Campylobacter species, C. jejuni and C. coli at both the genomic and phenotypic level. This has led to inconsistent findings when investigating the mechanisms by which Campylobacter spreads from the chicken gastrointestinal tract to edible tissues using in vitro and in vivo models. Feed additives are an increasingly popular alternative to antibiotic use in poultry farming; they present low risk of increasing antibiotic resistance and can be administered easily through food and/or water. The aim of this study was to determine the potential of three feed additives and four probiotic species as preventative measures for Campylobacter extraintestinal spread in poultry production. In chapter 3, a collection of Campylobacter isolates were sequenced and evaluated for their genotypic differences before being assessed in an avian and human cell line for their invasive capacity in vitro. Three isolates were selected based on their consistent in vitro invasive spectrum. In chapter 4, the selected Campylobacter isolates were challenged directly with feed additives to assess the impact on bacterial growth and motility. A significant reduction in Campylobacter growth was observed when challenged with 1.0% and 1.4% sodium butyrate over 24h. In chapter 5, human and avian cell lines treated with feed additives and exposed to Campylobacter isolates and focused on determining the cytotoxicity and any protective effects of the additives against transcellular invasion and cytokine production. Pre-treatment of epithelial cell monolayers did not significantly affect transcellular invasion of the bacterium. Chromium propionate significantly increased oxygen consumption in epithelial cells. Sodium butyrate at 0.6% increased epithelial cell production of inflammatory cytokines CXCLi1 and CXCLi2 . This thesis has; i) confirmed the diversity of Campylobacter species; ii) identified the direct inhibitory effects of feed additives on Campylobacter growth; iii) identified a novel mechanism of modified oxygen consumption by chromium propionate on epithelial cells; iv) identified the ability of sodium butyrate to induce CXCLi1/2 chemokines in avian epithelial cells. This work supports the growing evidence that feed additives are important alternatives for controlling Campylobacter in the chicken gut.

The Community Service Activities for the Independent Campus Learning Program (PkM MBKM), which involves lecturers and students has been done. The program aims to empower the people of Padukuhan Malangrejo, Wedomartani, Ngemplak Sleman, regarding the use of natural dyes for healthy food products. The targets during this program were 14 Women Farmers Group (KWT) participants, 10 elementary school students and 10 teenagers. In this course, we did the socialization of the activities, increasing the community literacy about natural food coloring and its benefits for health, by using the learning modules for children, adolescents and members of Women Farmer Groups (KWT). The training was carried out on the production of natural dyes that can be stored, as well as the creation of colorful food and drink recipes. Evaluation of literacy activities is assessed from understanding the material at the beginning (pre-test) and end (post-test) of the activity. Food products with natural dyes were organoleptically tested in communities outside Malangrejo. Other activities include assistance in the production of BiTel pudding (beetroot and butterfly pea coloring) with limited marketing, obtaining a Hygiene and Sanitation Certificate (SLHS) from the Health Service, Sleman. Activities to plant natural food dyes are carried out in yards and less productive land. Planting methods were adjusted to the type of plant, both horizontally and vertically. The results of the activity showed an increase in community participation and understanding of the benefits of natural food coloring (16.4%), increased literacy in the youth group (4%), KWT participants (2.9%), while for elementary school students there were 40% of participants who got a score of 100 %. This activity also gave rise to Micro, Small and Medium Enterprises (MSMEs or UMKM) which produce food with natural dyes, as well as the enthusiasm of KWT Malangrejo members in using their home gardens to produce natural food dyes. The MBKM PkM program for village development, which was implemented in Padukuhan Malangrejo, was well appreciated by the community and the Wedomartani Village leader, and hopefully the programs will continue in the following year.

Published: May 2024

Central Java province is the largest waste producer in Indonesia, with 4.25 million tons in 2022. Salatiga contributes quite a lot of waste in Central Java; according to data from the Salatiga City Communication and Information Service in 2018, organic waste (70%) and plastic (19%) were recorded. The objectives of the community service activity include increasing the housewives awareness, skills, and partnerships regarding the concept and actual practice of 3R (reduce, reuse, recycle). Activities include counseling, training, demonstrations, direct practice, Focus Group Discussion, mentoring, and evaluation of responses/output. The results of this activity conclude that the most significant potential waste from households in partner women groups (PKK) in Salatiga City is plastic waste, followed by food waste and waste from cooking activities. Community service activities trained and assisted in sorting and processing waste into economically valuable materials, namely compost, liquid organic fertilizer, artificial decorations, and various plastic creations, which received a positive response from the PKK group. The waste collection-sorting-deposit activity has been running in partner PKK groups up to 4 stages. However, only a few households have been involved due to a lack of time from family members, the hassle aspect, and the economic potential, which is not high enough. Processing organic waste into compost and POC, as well as inorganic waste into flower decoration creations, is an alternative application of the 3NG concept that housewives can carry out and is a PKK program. Interest in follow-up counseling and training is relatively high at a score of 4 on a scale of 1-5. This community service activity is expected to support national and global programs in improving care and the role of society in understanding waste management; community social entrepreneurship through processing waste into marketable products and education about environmental care to support a household-scale circular economy, supported by partnerships with external parties including Waste Bank (BSI) and the government.

The program partner for this community service student creativity program is the youth posyandu in Tambakboyo Hamlet, Mliwis Village, Cepogo, Boyolali. The problem faced by partners is that health screening results are not given after the posyandu activities end so that teenagers do not remember their health history and teenagers do not make efforts to prevent health problems. Apart from that, youth posyandu activities still require a variety of counseling topics as well as effective and innovative delivery methods. The aim of this community service program is to solve the problems faced by partners health monitoring using the Z-Health application. The methods for implementing the PKM program include observation and survey of the needs of youth posyandu, preparation of educational materials, training on how to use the application and peer counseling for cadres, training on using the Z-Health application for teenagers, as well as assisting youth posyandu using the Z-Health application. The results achieved from this community service program are that through the Z-Health application, teenagers can monitor their health status, receive health education and receive counseling. With this, there is an increase in behavior to prevent non-communicable diseases with CERDIK behavior. There is also an increase in understanding regarding non-communicable diseases (NCDs) and an increase in knowledge of peer counseling for posyandu cadres.

Published: May 2024

A long-term imbalance in macronutrient intake, such as energy and protein intake, might result in chronic energy deficiency in pregnant women. Several factors can impact pregnancy such as knowledge level, socio-economic status, marriage, education, family economics, and marital status. Chronic energy deficiency in pregnant women can result in a low birth weight, which is then linked to stunting. The aim of this research is to find out the relationship between the level of knowledge, food consumption diversity, and nutritional intake in pregnant women who reside in the area of this cross-sectional quantitative research. By using chi-square analysis, the result of these variables was determined. The result shows that the factors relate to energy deficiency in pregnant women with the details as knowledge with p-value = 0.0002, food variation with p-value = 0.0003, energy intake with p-value = 0.0022, protein consumption with p-value = 0.051, and fat with p-value = 0.005. However, the consumption of carbohydrates, lipids, vitamin IC, folic acid, iron, calcium, and iodine do have an effect but to the minimum extent in regards to chronic energy deficiency of pregnant women.

Published: May 2024

We present the rare case of a 67-year-old male patient, with a history of stunted cardiopathy of unknown etiology especially without associated cardiovascular risk factors, who presented a progressive bilateral visual loss. The best corrected visual acuity was 1/10 on both eyes with normal anterior segment and intra-ocular pressure. Fundus examination showed angioid streaks with bilateral macular neovascular membrane more severe in the right eye. The macular optical coherence tomography showed choroidal neovessels associated with intra-retinal cystoid macular edema in both eyes. A skin examination revealed an advanced pseudoxanthoma elasticum undiagnosed, which is at the origin of the angioid streaks with macular neovascularization, and most likely the cardiopathy.
Precision Modulation and the Shadow Blister Phenomenon in Optical Diffraction Using Straight-Edge Apertures
Authors: Vedad Farhad
Published: May 2024

The shadow blister effect, depicting the distortion of shadows when two objects overlap, is an optical phenomenon observable in sunlight without requiring specialized lab equipment. Despite its seemingly straightforward nature, this effect challenges explanation through ray theory and the Fresnel diffraction equation in certain regions. Conversely, the shadow blister effect exhibits both linear and nonlinear behavior corresponding to the steady variation of the transverse distance between the two unplanar straight edges along the optical axis. This article explores the shadow blister effect alongside the diffraction of a straight edge, revealing fundamental aspects of the diffraction phenomenon.
The experimental study introduces a diffraction model adept at elucidating the shadow blister effect. This model relies on an inhomogeneous fractal space, potentially generated by objects near their surfaces, including the edges of barriers.

Published: May 2024

Background: Submaximal exercise tests using treadmills are reliable predictors of cardiovascular and musculoskeletal performances in adults. Understanding neuromuscular lower extremity muscle activation during treadmill walking can help clinicians tailor rehabilitation and training programs for their condition.
Subjects: Ten healthy participants (22.6 ± 1.08 years of age) were recruited for this study.
Method: Participants were instructed to walk on a treadmill at a speed of 3.4 mph and 0% elevation for 3 min. The elevation increased every 3 min by 3% and 4% in women and men, respectively. Data on the muscle activation of the tibialis anterior (TA), gastrocnemius (GA), rectus femoris (QUADS), and semimembranosus (HS) were collected using surface electromyography.
Results: There were slight differences in the muscle activation between the muscle groups at various intervals. The results revealed that the tibialis anterior and semimembranosus took longer to activate and showed trends of more extended activation periods with an increase in inclination.
Conclusion: Analysis of electromyography (EMG) activity in healthy young adults during submaximal exercise testing on a treadmill revealed a delay in muscle activation and increased active time in the tibialis anterior and semimembranosus musculatures.

This study aims to determine the acceleration of gravity on the pendulum swing with video tracking method. The research was conducted through video on a simple pendulum swing experiment. The recorded video is imported into the Tracker app to get the period and frequency for each trial with different rope lengths. The rope length and mass data were measured manually, and the period and frequency data were obtained through video tracking analysis. The research results are shown in tables and graphs. Data analysis used a linear regression equation between the square of the period and the length of the pendulum. The magnitude of the acceleration due to gravity is obtained through the gradient of the quadratic equation and the length of the rope. The results show that the acceleration of gravity through video tracking analysis is 9.735 m/s2 .Keywords: pendulum swing, video tracking, acceletiation of gravity
