This document discusses different types of frequency distributions including relative frequency distribution, cumulative frequency distribution, and how to produce histograms and frequency polygons. It also covers key concepts like class intervals, class width, and calculating cumulative frequency and cumulative relative frequency.
This document discusses pancreatic enzymes and their assays from duodenal contents. It begins by describing the pancreas and its endocrine and exocrine functions. It then discusses the main pancreatic enzymes - lipase, protease, and amylase - and their roles in digestion. Normal levels of the enzymes are provided. Several methods for assaying pancreatic enzymes are described, including measuring levels in plasma, feces, and through stimulation and tubeless tests. Pancreatic disorders like acute pancreatitis, chronic pancreatitis, and pancreatic cancer are overviewed. The document concludes by emphasizing the importance of pancreatic enzyme assays for monitoring pancreatic function.
This document provides information about frequency distributions and constructing frequency distribution tables. It defines a frequency distribution as a representation of data in a tabular format showing the number of observations within intervals. It then outlines the general process for constructing a frequency table which includes determining the range, number of classes, class width, and recording the frequencies in a table. An example is provided of constructing a frequency table from data on the ages of 50 men who died from gunfire using 7 classes. Guidelines for constructing frequency tables are also listed.
The document describes the reflex arc, which is an automatic response to a stimulus that does not involve brain processing. A reflex arc involves a stimulus being detected by a receptor which sends a signal through a sensory neuron to the spinal cord. In the spinal cord, the sensory neuron connects with an interneuron which then connects to a motor neuron. The motor neuron carries the signal to an effector such as a muscle to produce a response without conscious thought, as an example of withdrawing a hand from a hot stimulus. Complex reflexes like swallowing and blinking also follow this basic reflex arc process in the spinal cord and brainstem.
The document discusses different approaches to environmental ethics and attitudes. It describes the ecosystem approach which considers interrelationships between ecosystems. It then outlines three schools of environmental ethics: anthropocentrism prioritizing human well-being, biocentrism focusing on inherent rights of all life, and ecocentrism maintaining respect for the Earth. Three environmental attitudes are also defined: development promoting human control, preservation calling for resource preservation, and conservation balancing human and environmental needs through sustainable practices.
This chapter discusses different environmental worldviews and approaches to environmental ethics. It presents several philosophies for determining what is right and wrong from an environmental perspective, such as utilitarianism which evaluates based on the greatest good, and biocentrism which views all life as intrinsically valuable. It also outlines various worldviews including viewing humans as stewards of the planet versus being in charge of managing Earth. The chapter concludes by discussing the need for environmentally literate citizens to build a more sustainable society through understanding our interactions with nature and effective problem solving approaches.
This document discusses several key concepts in environmental ethics and management:
- Environmental ethics examines the moral relationship between humans and the environment and defines human obligations toward the non-human world.
- Anthropocentrism views nature as existing for human benefit while biocentrism argues all life has an inherent right to exist.
- Ecocentrism maintains the Earth itself has moral value and humans should treat it with respect.
- Environmental management aims to control human impact on resources to ensure ecosystem services for future generations through approaches like conservation and sustainability.
The document discusses different environmental worldviews and ethics related to humanity's relationship with the natural world. It outlines three main worldviews: planetary management, which views humans as apart from nature and able to manage resources for unlimited growth; stewardship, which sees humans as responsible managers of the Earth; and environmental wisdom, which views humans as dependent on and part of nature. It also discusses trends toward more sustainable worldviews and values, as well as strategies for developing more environmentally and socially just societies such as reducing consumption, pollution and waste.

The document discusses the nervous system and different types of neurons and reflexes. It describes sensory neurons that carry signals from receptors, motor neurons that carry signals to muscles and glands, and interneurons that connect sensory and motor neurons in the central nervous system. It also explains that a reflex arc is a direct connection between a sensory neuron, interneuron and motor neuron that allows for rapid involuntary responses. Several examples of somatic and autonomic reflexes are provided.
The document discusses issues related to human development, sustainable development, environmental ethics, resource consumption patterns, and equity disparities. It notes that Western countries consume far greater resources and energy per capita than Eastern countries. Urban areas rely heavily on rural resources, while rural communities suffer. The document provides suggestions for more equitable and sustainable resource use, such as conserving energy, using public transit, and reducing waste.
The document discusses environmental ethics and various principles related to it, such as respecting all life forms and nature, taking responsibility for human impacts, and considering long-term consequences of actions. It also mentions statistics about environmental problems like global warming, pollution, and loss of forests and species. Specific data is provided on air pollution deaths, waterborne diseases, and economic losses from climate change disasters. The document outlines some Indian environmental legislation and acts aimed at controlling degradation and improving quality of life.
The document discusses different approaches to environmental ethics, including anthropocentric, biocentric, ecocentric, and stewardship views. It provides examples of prominent thinkers who developed each approach, such as Aldo Leopold's land ethic and Arne Naess' deep ecology philosophy which argues that all life has intrinsic worth. The document also examines perspectives on humanity's relationship to the environment from frontier ethics, Judeo-Christian traditions, ecofeminism, and environmentalist Christianity.
This document discusses ethical issues and challenges in corporate environments. It outlines the key stakeholders of corporations, including shareholders, employees, customers, suppliers, creditors, governmental agencies, communities, and special interest groups. It then discusses several common ethical issues corporations face, such as developing an ethical culture, eliminating conflicts of interest, enhancing cross-cultural ethics, and promoting gender equality. It also examines causes of unethical practices, like greed, lack of experience, and poor organizational culture. Finally, it provides an overview of approaches to handling ethical dilemmas, including utilitarianism, communal acceptance, religiosity, and deontology.
There are 12 pairs of cranial nerves that originate from the brain. They are the olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, accessory, and hypoglossal nerves. Each nerve has specific functions, such as carrying sensory information for smell, vision, and taste, or controlling eye and facial muscle movement. Damage to certain cranial nerves can cause issues like Bell's palsy or an inability to speak or swallow.
This document provides an overview of medical ethics and its principles. It begins with introducing the concept of medical ethics, its importance and branches. It then discusses in detail the key principles of medical ethics - autonomy, beneficence, confidentiality, non-maleficence, and justice. It also outlines various ethical codes and regulations that guide medical practice, including the Hippocratic Oath, Declaration of Geneva, and ICMR guidelines. The document concludes by discussing public health ethics, research ethics, and punishment for misconduct.
This document summarizes the 12 cranial nerves, including their component (motor, sensory, mixed), function, origin point in the brain, and opening through the skull. It describes that cranial nerves I, II, and VIII are sensory nerves involved in smell, vision, and hearing respectively. Cranial nerves III, IV, VI control eye movement and pupil constriction. The trigeminal nerve (V) is mixed and innervates face sensation and muscles of mastication. The facial nerve (VII) is also mixed and controls face muscles and taste. The vagus nerve (X) is the longest and most complex, controlling heart rate, digestion and more.
The document discusses the main components and functions of the human nervous system. It explains that the nervous system is comprised of the brain, spinal cord, and nerves. The brain contains three main parts - the cerebrum, cerebellum, and brain stem. The cerebrum controls voluntary actions and stores data. The cerebellum coordinates movements and controls balance. The brain stem connects the brain to the spinal cord and controls neurological functions. The spinal cord and nerves transmit signals between the brain, spinal cord, and organs throughout the body.
The document summarizes the structure and function of the nervous system. It has two principal parts: the central nervous system (CNS), comprising the brain and spinal cord, and the peripheral nervous system (PNS) comprising nerves. The CNS integrates sensory input and dictates motor responses, while the PNS carries signals between the CNS and sensory receptors and effector organs. Neurons are the basic functional units and transmit signals via electrical impulses. Neuroglia provide support and insulation for neurons.
The nervous system is the master controlling and communicating system of the body. It has two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord and controls sensory input, integration of information, and motor output. The PNS connects the CNS to the rest of the body through nerves and allows for voluntary control of muscles and glands as well as involuntary reflexes. The nervous system monitors both internal and external changes through sensory receptors and responds through integration and motor functions to control the body.
The document discusses the blood supply of the brain. It begins by describing the two pairs of arteries that supply the brain - the vertebral and internal carotid arteries. These arteries are interconnected to form the circle of Willis at the base of the brain. The vertebrobasilar system arises from the vertebral arteries and forms the basilar artery, which divides into the posterior cerebral arteries. The internal carotid system gives rise to the anterior and middle cerebral arteries. These arteries and their branches supply different regions of the brain. The circle of Willis provides an important anastomosis between the two systems to ensure adequate blood flow to the brain.

Medically Assisted Dying in (MAiD) Ireland - Mapping the Ethical Terrain (May...Dr Ghaiath Hussein
This document outlines a presentation on mapping the ethical terrain of medically assisted dying (MAiD) in Ireland. It does not take a stance but provides a framework to guide conceptual discussion. It focuses on the decision, decision makers, and outcomes using Canada as an example country that has legalized MAiD. Key ethical questions are raised about patients' autonomy and consent, physicians' conflicting duties, and impacts on public perception and resource allocation. Data from Canada on MAiD providers and annual reported deaths is presented. The conclusion emphasizes the need for evidence from all stakeholders and learning from other jurisdictions' experiences before a decision is made.
Research or Not Research? This Is Not the Question for Public Health Emergencies

Speaker:
Ghaiath Hussein, Assistant Professor, Medical Ethics and Law, Trinity College Dublin, Ireland
About this Seminar:
Public health emergencies, whether natural or man-made, local or global, in peacetime or during armed conflicts are always associated with the need to collect data (and sometimes biological samples) about and from those affected by these emergencies. One of the central questions in the relevant literature is whether the activities that involve the collection of data and/or biological samples are considered ‘research’, with the subsequent endeavour to define what ‘research’ is and whether they should be submitted for ethical approval or not. In this seminar, I will argue that this is not the central question when it comes to research/public health/humanitarian ethics. Using the findings of a systematic review on the research conducted in Darfur and findings from a qualitative project that aimed at defining what constitutes ‘research’ in public health emergencies I will, alternatively, present what I refer to as the ‘ethical characterization’ of these research-like activities and how they can be ethically guided.
Medically assisted dying in (MAiD) Ireland - mapping the ethical terrainDr Ghaiath Hussein
This document provides an outline for a presentation on medically assisted dying (MAiD) in Ireland. It aims to establish an ethical framework for conceptual discussion of MAiD by considering: the decision, the decision makers, and the outcome. It does not endorse any viewpoint. The presentation raises several ethical questions around patient autonomy and consent, concepts of life and death, the role of healthcare providers, and impacts on community and public trust. Examples are provided from Canada, where MAiD is legal, to illustrate challenges in practice. The document stresses the need for evidence from all stakeholders and learning from other jurisdictions' experiences before legalizing MAiD in Ireland.

Breast cancer: Post menopausal endocrine therapyDr. Sumit KUMAR
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.
PGx Analysis in VarSeq: A User’s PerspectiveGolden Helix
Since our release of the PGx capabilities in VarSeq, we’ve had a few months to gather some insights from various use cases. Some users approach PGx workflows by means of array genotyping or what seems to be a growing trend of adding the star allele calling to the existing NGS pipeline for whole genome data. Luckily, both approaches are supported with the VarSeq software platform. The genotyping method being used will also dictate what the scope of the tertiary analysis will be. For example, are your PGx reports a standalone pipeline or would your lab’s goal be to handle a dual-purpose workflow and report on PGx + Diagnostic findings.
The purpose of this webcast is to:
Discuss and demonstrate the approaches with array and NGS genotyping methods for star allele calling to prep for downstream analysis.
Following genotyping, explore alternative tertiary workflow concepts in VarSeq to handle PGx reporting.
Moreover, we will include insights users will need to consider when validating their PGx workflow for all possible star alleles and options you have for automating your PGx analysis for large number of samples. Please join us for a session dedicated to the application of star allele genotyping and subsequent PGx workflows in our VarSeq software.

Are you looking for a long-lasting solution to your missing tooth?
Dental implants are the most common type of method for replacing the missing tooth. Unlike dentures or bridges, implants are surgically placed in the jawbone. In layman’s terms, a dental implant is similar to the natural root of the tooth. It offers a stable foundation for the artificial tooth giving it the look, feel, and function similar to the natural tooth.

5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

•As a child-bearer Restricted personal rights (vs. rights of the fetus
&/or the father?)
5. Conceptual Challenges
• Lack of guidance (moral status of fetus,
surrogacy, new RH technologies)
• Contradicting guidance (national vs. int’l)
• Different interpretations of notions in
guidance (int’l declarations)
• De-alignment of legal and ethical guidance
• Dominance of community values over
religious guidance (female circumcision)
• Abuse of variation in religious interpretations
▫ catholic church and pro-life groups
▫ irrational jurisprudence rulings (Fawtas)
6. Practical challenges in care provision
• Lack of gender-sensitive healthcare
▫ Waiting areas
▫ Privacy
▫ Confidentiality (e.g. husband access to the wife’s
medical information)
• Gender insensitive policies (e.g. consent)
• Male-led management
• Gender insensitive (discriminative) practices
(e.g. C-sections)
7. Examples of gender imbalanced care
• Men’s interference (marital authorization) in the women’s RH
decisions (contraception, abortion, protected sex);
• Diminished freedom of consent (in non-RH issues)
• Woman’s right to know (her spouse’s STD status, treatment
alternatives, etc.)
• STDs protection (and contraception) is more woman-dependant
(pills, IUCDs, hormonal therapy, etc.)
• Women with HIV/AIDS: right to treatment, stigmatization,
confidentiality, counseling strategies on pregnancy continuation/
termination, future child bearing, and use of contraception
• Breach of woman’s confidentiality by male family members
• Women get tested in ANC visits, while men are discovered only
on voluntary basis (except for visa purposes?)
• Women’s dependence on men to get access to care
• Undue denial of safe abortion, even when religiously allowed

9. Challenges related to research
Research Research
Research topics
methodologies oversight
•Clinically-focused • Inclusion/exclusion • Women’s issues
topics biases (risks) are not well
•Lack of gender- • Facility-based acknowledged
related studies on studies (access) • Ethical guidelines
determinants of • Consent are developed
• ‘don’t get pregnant mostly by ‘white
health
during trial’ men’
•Lack of studies on
• Inadequate • Gender-
vulnerable groups Imbalanced REC
among women (age, Compensation
memberships
sexual-orientation,
disability)
10. How our network can help in
resolving conceptual and
practical challenges to women’s
health & research?
11. Approach to ethical challenges in healthcare
• Individual level
▫ Raise awareness about patients right, in general, and women’s
right in particular
▫ Positive involvement of men in advocacy for women
▫ Assist in minimizing the women’s illiteracy and financial
dependence
• Organizational/Institutional level
▫ Provide gender-sensitive care (waiting areas, examination
rooms ,etc.)
▫ Train providers on ethics (FAB)
▫ Balanced gender management
• Policy-making level
▫ Develop gender-sensitive policies
▫ Encourage women involvement in policy-setting
▫ Continuous communication with Ulama (scholars) regarding
women health
▫ Advocate for women’s health issues among politicians and
policy makers
12. Approach to ethical challenges in
research
• Train researchers in research ethics, especially vulnerability
• Improve gender balance in REC structures
• Educate ethics committees members on women’s health
research, gender analysis, and participatory action
methodologies, and to ensure gender issues and analysis are
part of funding criteria
• Train more female researchers on research methods and
ethics
• Encourage/Adopt community-based methodologies
• Review the current guidelines to makes them more gender-
sensitive
• Funding agencies should encourage research with members
reflecting the diversity of the population;
• North-South exchange of experience and head for sustainable
development, guided by the MDGs related to maternal health
