The peafowl died suddenly and unexpectedly. Upon examination, the veterinarian found the peafowl's crop was severely impacted with food material, likely causing it to starve. The cause of death was determined to be crop impaction.

Difference between Apoptosis versus Necrosis and Types of Necrosis.pptxRukhshanda Ramzaan
Apoptosis Versus Nercosis
Apoptosis Necrosis
Predefined cell suicide or programmed cell death. Natural physiological Process. Involve one cell at a time. Cell shrinkage (Dense eosinophilic cytoplasm) Pyknosis (Condensation) and Karyorrhexis (fragmentation) of nuclear material Formation of membrane blebs and apoptotic bodies
Phagocytosis of apoptotic bodies by Macrophages
Caspase dependent pathway
No Inflammation (no immune response) Premature, unprogrammed cell death always pathological. Involve many cells Cell Swelling (Swelling of endoplasmic reticulum and mitochondria) and membrane blebs Pyknosis (condensation), Karyorrhexis (Fragmentation) and Karyolysis (lysis)of the nucleus. Breakdown of the plasma membrane, organelles (enzymatic digestion), leakage of cellular contents
Increased eosinophilia, Accumulation of Myelin figures (whorled precipitated Phospholipids)
Initiate Inflammation (Strong immune response)
Difference between reversible and irreversible cell injury,Mechanism of cell ...Rukhshanda Ramzaan
Cell Injury: Any change resulting in loss of the ability to maintain the normal or adapted homeostatic state.
Agents that cause cell injury
• Hypoxia / Ischemia (loss of blood supply)
• Microbial
• Parasitic
• Chemical
• Physical
• Trauma
• Genetic
• Nutritious
• Environmental
Types of Cell injury
Reversible Cell Injury
Pathologic changes that can be reversed in mild cellular injury when the stimulus is removed. Cell injury is reversible only up to a certain point otherwise it will be irreversible.
Changes in reversible cell injury
Cellular Swelling: Due to accumulation of intracellular water and endoplasmic reticulum & mitochondria.
Clumping of chromatin.
Irreversible Cell injury
Pathologic changes that are permanent and cause cell death, they cannot be reversed to normal state.
Changes in irreversible cell injury
Irreversible injury is marked by severe mitochondrial vacuolization, extensive damage to plasma membranes, detachment of ribosomes from the granular endoplasmic reticulum (ER). Injury to lysosomal bodies leads to leakage of lysosomal enzymes into the cytoplasm and condensation, fragmentation and lysis of nuclei.

Cellular Response to cell Injury and Cellular Adaptations .pptxRukhshanda Ramzaan
Cellular Adaptations
ability of cells to respond to various types of stimuli and adverse environmental changes
Atrophy(decrease in cell size)
Hypertrophy(increase in cell size)
Hyperplasia(increase in cell number)
Metaplasia(change in cell type): Replacement of one differentiated cell type with another mature differentiated cell type that is not normally present in that tissue.
Dysplasia (increase in abnormal cell): Dysplasia is not cancer, but it may sometimes become cancer.
Terminologies used in Disturbances of Cell Growth which are not adaptations
Agenesis refers to the failure of an organ to develop during embryonic growth and development
Hypoplasia is the underdevelopment or incomplete development of a tissue or organ. It is technically not the opposite of hyperplasia (too many cells). Hypoplasia is a congenital condition, while hyperplasia generally refers to excessive cell growth later in life.
Aplasia is a birth defect where an organ or tissue is wholly or largely absent. It is caused by a defect in a developmental process.

Anti ulcer drugs and their Advance pharmacology ||
Anti-ulcer drugs are medications used to prevent and treat ulcers in the stomach and upper part of the small intestine (duodenal ulcers). These ulcers are often caused by an imbalance between stomach acid and the mucosal lining, which protects the stomach lining.
||Scope: Overview of various classes of anti-ulcer drugs, their mechanisms of action, indications, side effects, and clinical considerations.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
