A book with a strong women trope is my love language🔥🔥🔥

Sometimes a hot drink and a good book are enough to relax

I love and at the same time hate autumn exam sessions

Goblin(my cat) sends you hello, because I'm on my exam period, so have no time to post something

Keep going. You can stop after you get that dream

📍National Uzbekistan park, Tashkent

When I look at the moon I forget about all my worries. Thank heaven that there is such a miracle in it

The vibe in the bookstores 💘💘💘💘

Don't bother me, I'm on my ✨exam period✨

Finally i feel like I can do it even there are apocalypse (hope no@_@)

Let's try hard today for tomorrow's us

Today has not been a very productive day but it's okay. We need to be gentle with ourselves more often :з

Hi there ^~^

Another day - another chance

Finally, i did it!

Someone: where do you usually study?

Me: ... everywhere

Hi :)

Have you ever drawn in the margins of your textbooks/notebooks? This allows to relax a little and lifts spirits

Hi :) I haven’t posted anything for a long time because I gave myself a challenge of 30 days of study and nothing extra. I spent this month very productive, but now I want to do the “100 days of productivity” challenge and share my successes

It looks so cool, isn't it?

I want to study here 😩💘

Who said, that arabic is easy to learn😩

Hi :)

It was a long but very productive day

Studying all day

i am fighting tears this language is a punishment even my ginger tea isn't helping

tuesday, feb 11th

i survived! today was exciting but really stretched my brain. this week is really big for my research- i'm doing my first self-designed experiment tomorrow and i'm excited/scared/uncertain. i'm trying to remind myself that fear and excitement feel the same to our body, it's just how we think about those physical feelings that changes the mental feelings.

i’ve also been grappling with…why i do what i do. like, ultimately we’re all little specs of matter and energy that are so small in the grand scheme of things. and it’s been hard lately to not just give up and let god take the wheel.

but we’re all here for some purpose. ultimately god (whoever they are) has HAD the wheel for a while and we’re all just…going along for the ride. we’re lucky to have the resources, opportunities, and people that we have, and should always work for more.

while it doesn’t seem like it, it’s a blessing to be stressed about school. it’s a blessing to worry about grades. because at least we CAN worry about grades. at least we CAN worry about school.

education is a human right—but right now it feels like a gift.

to do:

finalize experiment for tomorrow

start working through data analysis for instrumentation lab

modeling homework

🎧: mendelssohn string octet

thursday, jan 30th

guys lookit this salad i made. normalize unaesthetic food pictures. i lowkey also ate so much deep fried food today. my lunch (is it still lunch if i ate at 3pm) was onion rings+fries with queso and ranch (so basically an oil rig) and my salad had some more of that breaded tofu i made yesterday but cut up.

not that it's wrong/bad to eat deep fried food. life is too short to regret.

i also am so cooked for my instrumentation class right now. we begged and pleaded to get an extension and prof gave us 1 DAY. not even the weekend. it's not like he's going to grade it before next week's exam...so why the rush.

me in circuit jail:

modeling quiz was ok. i finished it! so therefore i successfully served cunt.

n e ways. i'm going to crank out as much as i can before i need to switch gears and do stuff for my instrumentation lab tomorrow.

tasks:

instrumentation homework. just do it. ✅ (big slay 4/6 problems done 2 days before the due date)

instrumentation pre-lab lecture. ✅ (guys this was so much shorter than what i'd thought it'd be)

optional: research proposal (fook dat im going to bed)

🍵: osmanthus tea.

🎧: Brahms Symphony 4, Beethoven Symphony 7 🤤

The Physiology Of The Liver

The liver is a vital organ responsible for numerous functions including metabolism, immunity, digestion, detoxification, and vitamin storage. It weighs around 2% of an adult’s body weight and is unique due to its dual blood supply from the portal vein (75%) and the hepatic artery (25%).

Cellular Structure

The liver’s functional unit is the lobule, which is hexagonal in shape. Each corner of the hexagon has a portal triad consisting of the portal vein, hepatic artery, and bile duct. The lobule is composed mainly of hepatocytes, which have distinct apical and basolateral membranes. Hepatocytes are categorized into three zones based on their function and blood supply:

Zone I (periportal region): Closest to the blood supply, involved in oxidative metabolism (e.g., gluconeogenesis, bile formation).

Zone II (pericentral region): Sits between Zones I and III.

Zone III: Farthest from the blood supply, primarily involved in detoxification and biotransformation.

Blood and bile flow in opposite directions within the liver. The space of Disse, between the hepatocytes and the sinusoidal lumen, contains Kupffer cells (macrophages) and Ito cells (fat-storing stellate cells).

Development

The liver develops from endodermal cells of the foregut as the hepatic diverticulum around the fourth week of embryonic development. It undergoes complex differentiation influenced by various pathways (e.g., Wnt/β-catenin, FGF). By the sixth week, the liver participates in hematopoiesis, and hepatocytes begin bile production by the 12th week.

Organ Systems and Functions

The liver interacts with multiple body systems:

Digestive and Metabolic Roles: Aids in digestion, stores fat-soluble vitamins, and handles cholesterol.

Hematological Functions: Produces clotting factors and proteins.

Detoxification: Metabolizes drugs and other xenobiotics through phase I (oxidation, reduction, hydrolysis) and phase II (conjugation) reactions.

Bilirubin Metabolism: Converts heme to unconjugated bilirubin, then conjugates it for excretion.

Hormonal and Protein Synthesis: Involved in thyroid hormone activation and synthesis of nearly all plasma proteins.

Related Testing

Liver function tests (LFTs), including ALT, AST, bilirubin, alkaline phosphatase, and gamma-glutamyl transpeptidase (GGT), help assess liver health. Imaging techniques like ultrasound, CT, and MRI are also employed to identify liver abnormalities.

Pathophysiology

Cirrhosis results from chronic liver injury (e.g., due to alcoholism, hepatitis B and C), leading to fibrosis and necrosis. It causes symptoms like portal hypertension, coagulopathy, and jaundice. Hepatitis viruses (A, B, C, D, E), autoimmune diseases (e.g., primary biliary cholangitis), and metabolic conditions (e.g., non-alcoholic fatty liver disease) also contribute to liver pathology.

Clinical Significance

Understanding liver physiology helps manage conditions like viral hepatitis, alcoholic liver disease, benign liver lesions, and liver cancers. Early detection through appropriate testing and management strategies is essential for preventing end-stage liver disease and improving patient outcomes

Confused by ontology & epistemology? A short guide to help you navigate this aspect of research design

Introduction

For many graduate students pursuing advanced degrees like PhDs or Master’s, the realm of philosophical paradigms, ontology, and epistemology often appears daunting and abstract. Terms like positivism, constructivism, and critical realism can seem overwhelming, especially when these concepts play a fundamental role in shaping research methodologies and approaches. This guide aims to demystify these concepts step by step, providing clarity on their definitions, significance, and implications for academic research.

Understanding Ontology and Epistemology

At the heart of research design lie two foundational concepts: ontology and epistemology. Ontology concerns itself with the nature of reality — what exists and how it exists. It indulges into questions about the fundamental nature of the world, whether objective reality exists independently of human perception, or if reality is constructed through subjective experiences. Epistemology, on the other hand, investigates the nature of knowledge — how knowledge is acquired, validated, and understood. It explores the ways researchers come to know and understand phenomena, addressing questions about the validity of different sources of knowledge and the role of perception and interpretation in knowledge production.

The Role of Philosophical Paradigms

Philosophical paradigms provide overarching frameworks that guide researchers in defining their ontological and epistemological positions and in choosing appropriate research methods and methodologies. These paradigms include:

a). Positivism: Positivism asserts that knowledge is derived from observable phenomena and empirical evidence. It emphasizes objectivity, replicability, and the use of quantitative methods to test hypotheses.

b). Interpretivism: Interpretivism posits that knowledge is socially constructed through subjective experiences and interpretations. It focuses on understanding the meanings individuals attribute to their experiences, often using qualitative methods such as interviews, observations, and textual analysis.

c). Critical Realism: Critical realism seeks to bridge the gap between positivism and interpretivism by acknowledging the existence of an objective reality that is independent of human perception but also recognizing that our understanding of this reality is mediated through our perceptions and interpretations. It advocates for the exploration of underlying structures and mechanisms that generate observable phenomena while allowing for the influence of social contexts and human agency.

d). Constructivism: Constructivism proposes that knowledge is actively constructed by individuals based on their experiences and interactions with the world. It highlights the role of social and cultural contexts in shaping knowledge and emphasizes qualitative research methods that explore subjective meanings and interpretations.

e). Post-positivism: Post-positivism acknowledges the critiques of positivism while retaining its commitment to empirical observation and scientific vigor. It introduces concepts like theory-laden observation and the acknowledgment of researcher biases, aiming to refine positivist approaches to account for the complexities of social phenomena.

Navigating Different Philosophical Positions

Each philosophical position has implications for research design, methodology, data collection, analysis, and interpretation. Researchers must align their chosen paradigm with their research questions and objectives to ensure coherence and vigor in their studies. For instance:

1.Methodological Implications: Positivist research often employs quantitative methods to measure variables and test hypotheses, whereas interpretivist research favors qualitative methods to explore meanings and subjective experiences.

2. Ontological and Epistemological Assumptions: Understanding whether one believes in an objective reality (ontology) and how one believes knowledge is obtained and validated (epistemology) is crucial in selecting appropriate research methods and interpreting findings.

Advocating for Critical Realism

Critical realism emerges as a compelling philosophical stance that integrates insights from both positivism and interpretivism. It acknowledges the existence of an objective reality while recognizing that our understanding of this reality is mediated through social contexts, perceptions, and interpretations. Critical realism advocates for:

a) Causal Mechanisms: Exploring underlying structures and mechanisms that generate observable phenomena.

b) Contextual Understanding: Acknowledging the role of social contexts, historical conditions, and human agency in shaping phenomena.

c) Methodological Pluralism: Embracing a variety of research methods, both quantitative and qualitative, to capture different facets of complex social realities.

Conclusion

In conclusion, navigating philosophical paradigms, ontology, and epistemology is essential for any researcher aiming to conduct rigorous and impactful research. By understanding these foundational concepts and choosing an appropriate philosophical stance such as critical realism, researchers can enhance the depth and validity of their studies. This guide has provided a comprehensive overview of these concepts, empowering graduate students and researchers to articulate their research approaches confidently and contribute meaningfully to their fields of study.

What is Anemia of Chronic Disease?

Anemia of Chronic Disease (ACD), also known as anemia of inflammation or anemia of inflammation and chronic disease, is a prevalent condition often associated with chronic illnesses that last longer than three months and cause sustained inflammation. This form of anemia is particularly challenging because it not only stems from the chronic disease itself but also exacerbates the overall health burden on affected individuals.

Pathophysiology 

The pathophysiology of ACD is closely linked to the body’s inflammatory response. Chronic inflammation, which is a hallmark of many autoimmune diseases and long-term illnesses, significantly alters iron metabolism. Normally, iron is recycled from old red blood cells and used in the production of new ones. However, in ACD, inflammatory cytokines, particularly interleukin-6 (IL-6), stimulate the production of hepcidin, a hormone that regulates iron homeostasis. Hepcidin inhibits iron absorption in the gut and traps iron in macrophages, making it unavailable for red blood cell production, leading to a functional iron deficiency. Additionally, chronic inflammation can suppress erythropoiesis (the production of red blood cells) and reduce the lifespan of existing red blood cells, compounding the severity of anemia.

Epidemiology and Affected Populations

ACD is the second most common type of anemia after iron-deficiency anemia, particularly in populations over the age of 65. It is often seen in individuals with chronic conditions such as cancer, chronic kidney disease (CKD), heart failure, and a range of autoimmune diseases including rheumatoid arthritis, systemic lupus erythematosus (SLE), and inflammatory bowel diseases like Crohn’s disease and ulcerative colitis. The prevalence of ACD in these populations highlights the importance of understanding and managing this condition effectively to improve overall patient outcomes.

Clinical Presentation

The clinical symptoms of ACD are often subtle and can overlap with those of the underlying chronic disease. Common symptoms include fatigue, weakness, pallor, shortness of breath, and dizziness. These symptoms may be exacerbated during physical activity. However, the mild nature of ACD symptoms means that the condition is often underdiagnosed or attributed solely to the chronic disease without recognizing the contribution of anemia.

Diagnosis and Laboratory Findings

Diagnosing ACD involves a combination of clinical evaluation and laboratory testing. Blood tests are crucial for identifying the characteristic features of ACD, including low hemoglobin levels, normal or elevated serum ferritin (reflecting adequate iron stores), low serum iron, and low transferrin saturation. The reticulocyte count is typically low, indicating reduced erythropoiesis. In some cases, a bone marrow biopsy may be conducted to assess iron stores directly and rule out other causes of anemia.

Management and Treatment Strategies

The primary approach to managing ACD is to address the underlying chronic condition. Effective treatment of the chronic disease often leads to an improvement in anemia. However, in cases where the anemia is severe or the chronic disease is difficult to control, additional interventions may be necessary. These can include:

Erythropoiesis-Stimulating Agents (ESAs): Synthetic forms of erythropoietin (EPO) can be administered to stimulate red blood cell production. This is particularly useful in patients with chronic kidney disease or cancer, where endogenous EPO production is impaired.

2 .Iron Therapy: Although oral iron supplementation is typically less effective in ACD due to hepcidin-induced iron sequestration, intravenous iron therapy may be beneficial, particularly when combined with ESAs.

3 .Blood Transfusions: In cases of severe anemia, blood transfusions may be required to rapidly increase hemoglobin levels. However, this is generally considered a short-term solution due to the potential risks of iron overload and transfusion-related complications.

Prevention and Lifestyle Modifications

While ACD itself may not be preventable due to its association with chronic diseases, patients can take steps to support overall health and potentially mitigate the severity of anemia. A balanced diet rich in iron (from sources such as lean meats and dark leafy greens), folate, vitamin B12, and vitamin C can support healthy red blood cell production. Regular monitoring of iron levels and timely medical intervention are essential in managing ACD effectively.

In conclusion, Anemia of Chronic Disease is a complex condition that requires a broad approach to diagnosis and management. Understanding the interplay between chronic inflammation and iron metabolism is key to effectively treating this form of anemia. Through careful management of the underlying disease and appropriate use of adjunct therapies, healthcare providers can significantly improve patient outcomes and reduce the burden of this condition.
