This document discusses a research project on the relationship between depression and rheumatoid arthritis. The hypothesis is that depression may act as an initial factor that awakens rheumatoid arthritis, an autoimmune disease. To test this, the study will compare female patients in the early stages of arthritis who have suffered from depression to similar patients who have not suffered from depression. The methodology involves questionnaires addressing different levels of depression relating to topics like financial problems, self-esteem, and relationships.

Malaria prevalence and treatment seeking behaviour
Malaria is a major health problem in Nigeria, affecting 97% of the population. Each year there are an estimated 100 million cases of malaria in Nigeria, resulting in over 300,000 deaths. Malaria prevalence is highest in children ages 5-59 months in southern, central, and western Nigeria. Repeated malaria infections contribute to severe anemia and increased risk of death in children under 5 years old. This study aims to understand the current prevalence of malaria in Nigeria, environmental factors that allow transmission, and behaviors regarding treatment seeking for the disease. It also aims to educate the public about the effectiveness of insecticide-treated bed nets in preventing malaria transmission.
Defining Terms Of The Lymphatic & Immune System
Immunology is the study of the immune system and its functions in health and disease, including issues like hypersensitivities, transplant rejection, and autoimmune disorders. The immune system can become compromised, as seen in immunodeficiency disorders like HIV/AIDS where the virus attacks the immune system. Autoimmune diseases occur when the immune system mistakenly attacks the body's own healthy cells, often affecting organs like the lungs and kidneys. While not curable, autoimmune diseases are typically treated with immunosuppressant drugs that decrease the immune response.

The document discusses several factors that contributed to the extinction of the Inca Empire and indigenous populations in America:
1) Francisco Pizarro's small Spanish force was able to defeat the large Inca army due to infectious diseases like smallpox and measles that the indigenous people lacked immunity against.
2) Livestock brought by Europeans like pigs carried these infectious diseases and the indigenous Americans did not have domesticated animals, preventing the development of immunity.
3) Environmental factors like humidity and rainfall patterns influenced the spread of pathogens carried by animals and insects.
4) Modern epidemiological tools like STEM (Spatiotemporal Epidemiological Modeler) and big data analytics can help scientists better

The document discusses ways to strengthen the immune system in the third age. It begins by explaining what the immune system is and how it functions. It then describes the changes that occur in the immune system during the third age, including it becoming less effective at distinguishing self from non-self and responding more slowly to new antigens. Finally, it outlines several approaches that can be used to boost immunity in older adults, such as specialized vaccines, drugs that alter metabolism and senolytics that target senescent cells. It also stresses the importance of an overall healthy lifestyle.

Neuroimmune responses in the developing brain following traumatic brain injur...Adventist University of the Philippines
This document summarizes the neuroimmune response in the developing brain following traumatic brain injury (TBI). It discusses how the immune system plays a key role in normal brain development and how an immune response after TBI can disrupt this process. The immune response to TBI involves both the innate immune system through activation of microglia and infiltration of cells like neutrophils, as well as the adaptive immune system with lymphocytes migrating to the injury site. Younger patients are more susceptible to long-term effects of TBI due to the disruption of ongoing brain development by the neuroinflammatory response. Modulating this immune response may help enhance repair after pediatric TBI.Pathogenesis Essay
The pathogenesis of NF1 is complex and involves interrelationships between various elements that manifest at different ages. Café-au-lait spots typically appear in the first year of life, while NF2 vestibular schwannomas usually develop later in the third decade. Symptoms of Schwannomatosis also appear later in life and are non-specific, like pain. Understanding how clinical signs relate to a person's age can help with healthcare and provide insights into pathogenesis. In some cases, genetic analysis may help with diagnosis when clinical symptoms are unclear. Somatic mosaicism can also contribute to limited signs and symptoms.
Review Paper
This document summarizes information about rheumatoid arthritis (RA), including its risk factors, potential treatments, and the drug methotrexate. RA is an autoimmune disease that affects about 0.5% of adults worldwide and predominantly impacts women. Genetic and environmental factors are thought to trigger RA. Methotrexate is currently considered the primary treatment for RA and is administered to around 70% of patients with the disease. The document also outlines a three-phase treatment plan for RA and discusses the use of methotrexate both orally and via injection.

semo2036
This document discusses chronic diseases and their control. It notes that chronic diseases have replaced infectious diseases as the leading causes of death in the United States. Chronic diseases are characterized by uncertain causes, multiple risk factors, long development periods, and disability rather than cure. The document outlines the continuum of chronic disease from upstream social determinants to behavioral risks to conditions to diseases to impairment. It provides examples of how chronic diseases and their risk factors are interrelated and complex. Effective control requires addressing many determinants and preventing progression along the continuum.

The document discusses several key points:
1) It questions the common belief that childhood exposure to measles provides immunity and that avoiding it threatens health.
2) It suggests that genetically modified foods and agricultural chemicals may promote disease more than genetics.
3) It warns that mandatory vaccinations could require Americans to accept poor and chronic health. Overall, the document casts doubt on mainstream views of health, immunity, and the role of vaccines and industrialized foods.

This document examines the encephalogenic and HLA-DR binding capacities of various myelin peptides. It constructs recombinant HLA-DRβ1 complexes containing peptides from myelin proteolipid protein, myelin oligodendrocyte glycoprotein, and myelin basic protein. These complexes are transfected into insect cells to evaluate surface expression and autoantigenic activity. Individual myelin peptides are also tested for their ability to induce experimental autoimmune encephalomyelitis in transgenic mice. The data shows that two specific sheath peptides induced multiple sclerosis-like paralysis when injected into HLA-DRβ1-15.01 mice, indicating a role in multiple sclerosis induction. Ultimately, the peptide-HLA complexes will be used
Non-Communicable Diseases
This document discusses various health issues affecting society such as neurological disorders, cardiovascular diseases, cancers, and mental health disorders. It attributes the rise of these non-communicable diseases to factors like toxic food, lack of activity, toxic medical care, and toxic lifestyles. Various studies and data are presented arguing that vaccines, pharmaceutical drugs, and modern western diets high in processed foods and industrial oils are significant contributing causes of the growing chronic disease burden through their toxic and epigenetic effects. Alternative views of health, disease, and medical treatment are proposed focusing on homeostasis, allostasis, and lifestyle-based primary prevention approaches.
Neuro immunology-2018--abstract- luisetto m
The document proposes applying toxicology approaches to better understand some neurobiological phenomena. It suggests that local microenvironments and the timing of immune system influences could play a role in certain brain pathologies. Specifically, it hypothesizes that immune system imbalances or shocks during critical periods of growth and development could impact neuronal connectivity and apoptosis, potentially leading to conditions like autism. The author argues that considering intra-cellular toxicology factors over time may provide new insights into the etiology, diagnosis and treatment of neurological disorders.
evolutionary Medicine
Evolutionary medicine helps explain many mysteries of the human body by considering how our bodies have evolved in response to environmental pressures. It provides insight into why we are vulnerable to diseases and medical issues. For example, it explains why early reproduction occurs even if it leads to lower birth weight offspring, as this represents an evolutionary trade-off. The document also discusses how the battle between mother and fetus for glucose and the hygiene hypothesis help explain medical issues. Overall, evolutionary medicine combined with modern medicine can help discover new treatment options and improve current ones.
Final Thesis 4.21
This honors thesis examines the potential for acetaminophen to potentiate the effects of oxidant air pollutants and contribute to the onset of asthma. Using a mouse model, the study found that low, non-toxic doses of acetaminophen greatly increased the reflex irritant response to environmental tobacco smoke, likely by increasing oxidative stress in the airways. This is notable because acetaminophen usage has risen along with asthma rates in recent decades. The results suggest acetaminophen's metabolite NAPQI may potentiate the effects of oxidant pollutants, representing a possible new link between acetaminophen and asthma development.

Bioinformatics in pandemic Script
This document discusses the use of subtractive genomics to identify potential drug targets for pathogenic organisms. Subtractive genomics involves subtracting the sequences between a host and pathogen's proteome to identify proteins essential to the pathogen but not present in the host. This approach has been applied to identify drug targets for multi-drug resistant pathogens like Salmonella typhi and Listeria monocytogenes, as well as pathogens with no existing effective drugs like Leishmania donovani and Clostridium botulinum. Identifying novel drug targets through subtractive genomics can help develop new defenses against antibiotic-resistant pathogens and treat diseases currently lacking effective treatments.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Depression as a factor in Rheumatoid Arthritis disease
- 1. by José E. Ramos BIOL 3009L RISE Program: Summer Bridge 2014
- 2. What research project will I work? Why is it important to know about this problem? How will I do this research?
- 3. Rheumatoid Arthritis It’s a systemic auto-immune disease that affects between 0.5% and 1% of the adult population worldwide.
- 5. The immune system is very complex and plays a direct role in autoimmune diseases (such as autoimmune hepatitis and rheumatoid arthritis). Structure of the immune system.
- 6. Depression Depression acts as an inflammatory disorder because the plasma levels of two cytokines are increased: i.e. interleukin-(IL)-6 tumor necrosis factor-α (TNFα) (Maes, M. 2010, )
