Gregor Mendel studied traits in pea plants such as color and height. He found that traits are controlled by alleles - dominant alleles will be expressed over recessive alleles in the first generation. Through subsequent generations and self-pollination, he discovered that recessive traits can be expressed according to his laws of inheritance and principles of dominance and segregation. Mendel's experiments laid the foundations for modern genetics.

Biology is the study of life through the science of living things. It examines the characteristics of life including cellular composition, growth, reproduction, movement, adaptation, metabolism, specific organization, homeostasis, and responsiveness. Cells are the basic unit of structure and function, and organisms can be unicellular or multicellular. Reproduction can occur asexually through cell division or sexually through the union of sex cells. Adaptation allows organisms to change to meet environmental needs through behavioral, physiological, and structural modifications. Metabolism converts food to energy through chemical reactions while homeostasis maintains stable internal conditions.
Scientists classify living things into a system of organization. They first divide all living things into two main groups: plants and animals. Animals are then divided into those with backbones (vertebrates) and those without (invertebrates). Vertebrates include mammals, birds, reptiles, amphibians and fish. Plants are divided into flowering and non-flowering. As classification developed over time, more subgroups were identified to place various species.

DIVERSITY IN LIVING WORLD - (CLASS XI, CBSE BIOLOGY)BIOLOGY TEACHER
Biology is the science of life forms and living processes. Early humans could perceive the difference between living and non-living things. All living things share certain characteristics including growth, reproduction, metabolism, response to stimuli, and cellular organization. However, not all characteristics apply to all living things. The systematic classification and naming of organisms is necessary to effectively study the diversity of life on Earth.
This chapter introduces the key concepts of biology. It discusses that life is diverse yet shares common characteristics. It explores the different levels of biological organization from cells to organisms to ecosystems. Key concepts covered include the cell theory, theory of evolution, homeostasis, and the scientific method. The chapter emphasizes that biology studies both the diversity and unity of life.
This document discusses biology and the classification of living organisms. It begins by defining biology as the science of life forms and processes. It then discusses how early humans could distinguish living from non-living things. The development of systematic classification brought identification, nomenclature and categorization of organisms. This recognition of relationships between organisms showed they shared similarities and evolved from common ancestors. The document then outlines the classification of the kingdoms of plants and animals.
This document discusses the classification of organisms. It explains that scientists classify living things to organize and study them more easily. Early systems like Aristotle's grouped animals based on how they moved, but Linnaeus improved on this by classifying organisms according to observable features. His system uses binomial nomenclature, giving each organism a two-part scientific name. Organisms are classified into seven main levels from broadest (kingdom) to most specific (species). The document provides an example of classifying a brown squirrel through these seven levels.
Biology has many branches that study different aspects of living organisms. Some of the main branches described in the document are paleontology, genetics, ecology, zoology, botany, pathology, entomology, phycology, cytology, ornithology, physiology, herpetology, and morphology. Each branch name comes from Greek or Latin roots referring to what it studies, such as "zoion" meaning animal in zoology.
This document provides an overview of the textbook "Integrated Principles of Zoology, 14/e" which examines animal life through the scientific study of zoology. The textbook is authored by Cleveland P. Hickman Jr., Larry S. Roberts, Allan Larson, Helen I'Anson, and David Eisenhour and includes 14 chapters discussing topics such as life and biological principles, cells, genetics, evolution, reproduction, and development. It uses principles of physics, chemistry, and the scientific method to explore different levels of biological organization from macromolecules to populations and evolutionary trends across species.
The document discusses the various branches of biology. It states that biology is the study of life and is concerned with all living things. It then lists and provides brief descriptions of many branches of biology, including zoology (animals), botany (plants), cytology (cells), ecology (relationships between living things and their environment), genetics (passing of features from parents to offspring), anatomy (internal organs), microbiology (microscopic life), taxonomy (classification of organisms), ornithology (birds), entomology (insects), parasitology (parasites), bacteriology (bacteria), mycology (fungi), virology (viruses), physiology (functions of tissues, organs and systems), morphology (appearance
Taxonomy is the science of classifying organisms and involves naming, describing, and arranging species into a classification system. Taxonomists have identified about 1.78 million species but the total number is estimated between 5-30 million. Taxonomy ranks species from most general to specific as domain, kingdom, phylum, class, order, family, genus, and species. The three domains are Bacteria, Archaea, and Eukaryota. Kingdoms include Animalia, Plantae, Fungi, and others. Classification systems continue to be revised as new research emerges.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...Oleg Kshivets
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

1. The Characteristics of Life - life exists almost everywhere on earth earth possesses a great
variety of diverse life forms all living things have certain characteristics in common are
organized reproduce and develop respond to stimuli are homeostatic grow and develop have
capacity to adapt organism (a living thing) - You must have all the characteristics of life in order
to be considered an _____________ Levels of Biological Organization - Atom, molecule, cell,
tissue, organ, organ system, organism, population, community, ecosystem, biosphere Cell -
Smallest unit of life tissue - a group of similar cells that perform a particular function organ -
several tissues join together to form an ___________ organ system - organs work together to
form an ______________ complex - each level has a characteristic added that makes it more
_________ than the level below it Energy - ability to do work Metabolism - all chemical
reactions to sastain life breaking down and building up (muscle, brain cell, etc) ALL chemical
reactions Reproduction - process of producing a new individual of the same kind (make more of
itself) development - change over time Genes - units of information within an individual's DNA
Deoxyribonucleic Acid - what does DNA stand for? avoiding injury, acquiring food, or mating -
behavior is directed towards: Homeostasis - "staying the same" refers to the requirement that
organisms maintain a relatively constant internal environment ex: human body temperature
Growth - increase in size or number of cells Development - changes that take place from
conceptions to death Adaptations - are features that make individuals organisms better suited
to the new environment pH blood range - 7.35-7.45 Natural selection - how evolution happens
(mechanism of evolution) results in change over time Evolution - Change over time (small
changes over lots of time) last characteristic of life Taxonomy - sorting things (branch of biology
concerned with identifying, naming organisms, and describing) Systematics - whole groups
(study of the diversity of life for the purpose of understanding the evolutionary relationships
between species) 8 organism classifications - domain, kingdom, phylum, class, order, family,
genus, species domain - largest classification category Domain Archaea, Domain Bacteria,
Eukarya - based upon biochemical and genetic evidence scientists have identified 3 domains:
prokaryotes - both domain archaea and domain bacteria contain single-celled
___________________ (unicellular) prokaryotes - organisms that lack a nucleus and the
membrane bound organelles that are typically found in eukaryotes eukaryotic cells (a true
nucleus) - domain eukarya include: Domain Archaea - Live in extreme environments
extremeophiles (love extreme environments) -too little 02, too salty, too hot, or too acidic for
most other organisms Domain Bacteria - bacteria found almost everywhere on the planet earth
some are present within humans some bacteria cause disease but many are beneficial Domain
Eukarya - (Eukaryotes) are further categorized into 4 kingdoms: Kingdom Protista, Kingdom
Fungi, Kingdom Plantae, Kingdom Animalia Categories of Classification (most inclusive to least) -
Domain, Kingdom, Phylum, Class, Order, Family, Genes, Species Domain Eukarya - cells with
nuclei Kingdom Animalia - multicellular, motile, ingestion of food Phylum Chordata - dorsal
supporting rod and nerve cord Class mammalia Order Primates - hair, mammary glands adapted
to climb trees Family hominidae - adapted to walk erect genes homo - large brain, tool use
species homo sapiens - body characteristics similar to modern humans binomial means - two
names biology - study of life bio-life ology-study goal of science - to know, gain new knowledge
2. observation - seeing with eyes, using senses scientific names - Homo sapiens Pisum sativum
Felis domesticus *must be Capital then lowercase and italicized scientific method - biologist and
all scientists generally test hypotheses using ____________________ scientific method - a
standard series of steps used in gaining new knowledge hypothesis - educated guess
Observation - natural phenomena may be better understood by observing and studying them
only questions about natural phenomena can be answered with science scientists use their
senses to make observations they can extend their abilities by using instruments inductive
reasoning - make observation to general statement using scientific observations and the
process of logic and reasoning to arrive at general scientific principles 1. testable 2. falsifiable
(verifiable)-prove that hypothesis is false (right or wrong) - a hypothesis must always be two
things: deductive reasoning - to determine how to test a hypothesis involves "if/then" logic
Prediction - step of the scientific process that follows the formulation of a hypothesis and
assists in creating the experimental design experimental design - is the manner in which a
scientists intends to conduct an experiment Experimental variable (independent variable) -
factor of the experiment being tested (normally in the "if/then" logic comes after the if. is the
variable that is changed to create the "then" Response variable (dependent variable) - what i
expect to happen result or change that to occur (usually comes after the "then" in a hypothesis
statement" the outcome of the change in the experiment control group - sample that goes
through all the steps of an experiment but does not contain the variable being tested model - a
representation of an actual subject for example: computer modeling to study climate changes
mice to perform cancer research conclusion - is the analysis of the data to determine if the
hypothesis can be supported or not
