Importance of Guidelines in Regulatory Toxicity studies
Guidelines are the consensus document accepted by a regulatory body
Prevent duplication of clinical trials in humans
Ensure SAFETY, EFFICACY and QUALITY of medicines
Minimize the use of animal testing without compromising safety and effectiveness
Safety pharmacology is a branch of pharmacology with its aim to predict the potential clinical risk profile of new chemical entities (NCEs).
It has the ability to predict the potential off-target drug effects on major organ systems which are associated with exposure in the therapeutic range and above.
As an essential part of the spectrum of drug discovery and development, safety pharmacology studies are generally conducted to determine the relative drug effect on main organs, including respiratory system, central nervous system, and cardiovascular system.Safety pharmacology is an essential part of the drug development process that aims to identify and predict adverse effects prior to clinical trials.
SP studies are described in the international conference on harmonization (ICH) S7A and S7B Guidelines.

ICH is the “International Conference on Harmonization of
Technical Requirements for Registration of Pharmaceuticals for
Human Use”
ICH is a joint initiative involving both regulators and research based industry representatives of the EU, Japan and the US in
scientific and technical discussions of the testing procedures required
to assess and ensure the safety, quality and efficacy of medicines
This presentation enlists all the studies which are required before submission of IND. It include IND introduction , time period of study ,flowchart showing preclinical studies...
Alternative methods to animals testing are the development and implementation of test method that avoid use of live animals or use of less animals in method.
The council directive on protection of animals used for experiments and scientific purpose in article 23
“The commission and member states should encourage
research into development and validation of alternative methods which could provide the same level of information as that obtained in experiment using animals but which involves less animal”.
Alternative methods able to do:
Reduce Refine Replace
collectively called as “The 3Rs Principle”.
Needs for alternative methods
Because in laboratory animals may be:
Poisoned.
Deprived of food water and sleep.
Applied with skin and eye irritants.
Subjected to psychological stress.
Deliberately infected with the infected disease.
The MTT assay and the MTS assay are colorimetric assays for measuring the activity of enzymes that reduce MTT or close dyes (XTT, MTS, WSTs) to formazan dyes, giving a purple color The main application allows to assess the viability (cell counting) and the proliferation of cells (cell culture assays)
It can also be used to determine cytotoxicity of potential medicinal agents and toxic materials, since those agents would stimulate or inhibit cell viability and growth

UNDERSTANDING OF CHEMICAL CARCINOGENESIS:CURRENT AND FUTURE PERSPECTIVES
Carcinogenesis refers to the process by which a normal cell is transformed into a malignant cell and repeatedly divides to become a cancer
Chemicals which initiate this process is called chemical carcinogens
Chemicals which increase the effectiveness of carcinogens is called co-carcinogens
CLASSIFICATION OF CHEMICAL CARCINOGENS
MECHANISM OF ACTION
STAGES OF CARCINOGENESIS
ROLE OF PROTO-ONCOGENES AND TUMOR SUPPRESSOR GENES
ACTIVATION OF PROTO ONCOGENES
INACTIVATION OF TUMOR SUPPRESSOR GENE
OXIDATIVE STRESS IN CARCINOGENESIS
ROS can be produced from both endogenous and exogenous sources
Attack both purine and pyrimidine bases, as well as the deoxyribose backbone
Induces DNA damage which includes single or double-strand breakage, deoxyribose modification, and DNA cross-link
If DNA damage is not properly repaired it may result in mutation which leads to cancer

Drug induced hepatotoxicity and its regulatory implicationsChander K Negi
Drug induced hepatotoxicity
Hepatotoxicity implies chemical-driven liver damage. Liver injury may be produced by a large variety of chemical substances The liver plays a central role in transforming and clearing chemicals and is susceptible to the toxicity from these agents Certain medicinal agents, when taken in overdoses & sometimes even when introduced within therapeutic ranges may injure the liver It might not be the drug that cause hepatotoxicity but its metabolite might The herbal drugs and agents can also cause the liver injury

Review Article: PROCESS ANALYTICAL TECHNOLOGY- Innovative pharmaceutical deve...Vignan University
Process Analytical Technology in pharmaceutical production checks the quality of the raw material attributes
both physically and chemically, that too off-line, in-line or on-line. Process analytical technologies have been
applied to manufacturing processes for decades. PAT is a system for design, analysis, and control of
manufacturing processes, 1
based on continuous monitoring/rapid measurements of critical quality and
performance attributes of raw material, intermediates and products. PAT involves measurement science by
using conventional process sensors such as pressure, temperature and probes. The PAT initiative was initially
intended for traditional pharmaceutical manufacturers, but the FDA.s, PAT guidance now clearly states that it
applies to all manufacturers of human and veterinary drug products. PAT involves shift from testing the quality
to building quality into products by testing at several intermediate steps. It specifically requires that
quantifiable, causal, and predictive relationships be established among the raw materials. There by decreasing
the chances of contamination and cross contamination. It also saves a huge amount of time and money required
for sampling and analysis of the products. Overall PAT paves a way for producing a quality product thus
satisfying the customer needs and creating a good brand image for the organization. PAT that will encourage
the voluntary development and implementation of innovative pharmaceutical development, manufacturing, and
quality assurance as well as novel analyzer technologies.

The International Classification of Diseases (ICD) is a globally recognized system for classifying and coding diseases, health conditions, and related factors. It is maintained and updated by the World Health Organization (WHO) and serves several critical functions in healthcare and epidemiology. To describe the ICD comprehensively within 3000 characters, we'll cover its history, purpose, structure, and significance.
**History:**
The roots of the ICD can be traced back to the mid-19th century when various countries began documenting statistics on causes of death. The need for a standardized classification system became evident as different nations used their own systems, hindering international comparisons. The ICD was officially established in its modern form in 1948, with subsequent revisions and updates.
**Purpose:**
The primary purposes of the ICD are as follows:
1. **Disease Classification:** The ICD provides a systematic way to categorize diseases and health conditions. Each condition is assigned a unique code, which simplifies data collection and reporting.
2. **Clinical Diagnosis:** Healthcare professionals use the ICD to document and communicate diagnoses. This aids in patient care, medical billing, and insurance claims processing.
3. **Epidemiology:** The ICD is crucial for monitoring and analyzing disease patterns on a global scale. It helps identify emerging health threats, allocate resources, and develop public health policies.
4. **Health Statistics:** Governments and health organizations use the ICD to compile health statistics, such as causes of death and disease prevalence. This information guides healthcare planning and resource allocation.
**Structure:**
The ICD is organized into chapters, sections, and codes. The current version, ICD-10, is divided into 22 chapters, covering a wide range of health-related topics. Here's an overview of some key chapters:
- **Chapter I:** Certain infectious and parasitic diseases
- **Chapter II:** Neoplasms (cancers)
- **Chapter III:** Diseases of the blood and blood-forming organs
- **Chapter IV:** Endocrine, nutritional, and metabolic diseases
- **Chapter V:** Mental and behavioral disorders
- **Chapter VI:** Diseases of the nervous system
- **Chapter VII:** Diseases of the eye and adnexa
- **Chapter VIII:** Diseases of the ear and mastoid process
- **Chapter IX:** Diseases of the circulatory system
- **Chapter X:** Diseases of the respiratory system
- **Chapter XI:** Diseases of the digestive system
- **Chapter XII:** Diseases of the skin and subcutaneous tissue
- **Chapter XIII:** Diseases of the musculoskeletal system and connective tissue
- **Chapter XIV:** Diseases of the genitourinary system
- **Chapter XV:** Pregnancy, childbirth, and the puerperium
- **Chapter XVI:** Certain conditions originating in the perinatal period
- **Chapter XVII:** Congenital malformations, deformations, and chromosomal abnormalities
- **Chapter XVIII:** Symptoms, signs, and abnormal clinical and labor

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
