At its most basic, biochemistry is the study of the chemical processes occurring in living matter. However, this simple definition encompasses an incredibly diverse field of research that touches nearly all aspects of our lives.
the branch of science concerned with the chemical and physico-chemical processes and substances that occur within living organisms.
the processes and substances with which the science of biochemistry is concerned.
Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms.[1] Biochemical processes give rise to the complexity of life.
What is biochemistry?
Biochemistry explores chemical processes related to living organisms. It is a laboratory-based science combining biology and chemistry.
Biochemists study the structure, composition, and chemical reactions of substances in living systems and, in turn, their functions and ways to control them. Biochemistry emerged as a separate discipline when scientists combined biology with organic, inorganic, and physical chemistry. They began to study areas such as:
How living things get energy from food
The chemical basis of heredity
What fundamental changes occur in disease
Biochemistry includes the sciences of molecular biology, immunochemistry, and neurochemistry, as well as bioinorganic, bioorganic, and biophysical chemistry.
What do biochemists do?
Biochemists interact with scientists from a wide variety of other disciplines, usually on problems that are a very small piece of a very large and complex system.
Biochemists in industry are interested in specific applications that will lead to marketable products
Biochemists in academia or government labs conduct more basic and less applied research
Where is biochemistry used?
Biochemistry has obvious applications in medicine, dentistry, and veterinary medicine. Other applications include:
Food Science
Biochemists determine the chemical composition of foods, research ways to develop abundant and inexpensive sources of nutritious foods, develop methods to extract nutrients from waste products, and/or invent ways to prolong the shelf life of food products.
Agriculture
Biochemists study the interaction of herbicides/insecticides with plants and pests. They examine the structure–activity relationships of compounds, determine their ability to inhibit growth, and evaluate the toxicological effects on surrounding life.
Pharmacology, Physiology, Microbiology, Toxicology, and Clinical Chemistry
Biochemists investigate the mechanisms of drug actions; engage in viral research; conduct research pertaining to organ function; or use chemical concepts, procedures, and techniques to study the diagnosis and therapy of disease and the assessment of health.

Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility

Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

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

Biochemistry an overview
1. Biochemistry ‒ An Overview
R. C. Gupta
M.D. (Biochemistry)
Jaipur, India
2. Living organisms are made up of chemical
elements organized into bio-molecules
Important bio-molecules include nucleic
acids, proteins, carbohydrates, lipids etc
These are made up of C, H, O and N with
small amounts of some other elements
3. Several inorganic elements are also
present in living organisms
By themselves, the bio-molecules and
the inorganic elements are non-living
But when they come together in a cell,
they confer the property of ‘life’ to the cell
4.
5. Cell is the structural and functional unit of
all living organisms
It obtains raw materials required for
sustaining itself from its environment
From raw materials, it produces the
biological catalysts (enzymes) that
catalyse biochemical reactions in the cell
6. With the help of enzymes, the cell oxidizes
the bio-molecules to extract energy
It can convert raw materials into complex
molecules and supra-molecular assemblies
7. Chemical events occurring in the cell
keep it in a dynamic steady state, even in
a continually changing environment
And finally, the cell has the remarkable
ability to reproduce itself
8. Biochemistry encompasses
the study of:
Bio-molecules and elements
essential for life
The chemical reactions they
undergo to subserve various
functions of the organism
9. Unicellular organisms, e.g. bacteria, are
made up of a single cell having a simple
architecture
Multicellular organisms have a highly
organized cellular architecture
11. An adult human being has nearly 1014
cells
These cells are of different types having
different shapes, sizes and functions
12. The cells are organized into tissues and
tissues into organs
This differentiation gives us the advantage
of division of labour
But it also poses the problem of cell-cell
communication and co-ordination
13. A simple event like removing our hand
on touching a hot object involves a
series of reactions
14. These reactions occur in different types
of cells involving a number of ions and
molecules
Biochemistry seeks to explain such
complex biological phenomena at the
molecular level
15. The structural organization of cells
differs from organism to organism
But there is a remarkable degree of
unity in this diversity
The bio-molecules present in different
types of cells are similar
16. The information molecules, ribonucleic acid
and deoxyribonucleic acid, are similar
They are made up of the same nucleotides
The genetic code is the same
17. The proteins are made up of the same
twenty amino acids
The biological catalysts are similar
The currency of energy is the same
The metabolic pathways are similar
18. Due to this similarity, information
obtained in one organism can be
extrapolated to others
Much of the information about human
biochemistry has been obtained from
experiments in simple organisms like
bacteria
19. The scope of biochemistry is very wide
It covers plants, animals, microbes,
industry etc
Human biochemistry concerns the bio-
chemistry of human health and disease
20. Study of human biochemistry covers:
• Chemistry of amino acids and proteins
• Enzymes
• Chemistry of carbohydrates and lipids
• Metabolism of carbohydrates, lipids,
amino acids and proteins
• Bio-energetics and oxidative
phosphorylation
• Molecular biology
Continued …
21. • Vitamins and minerals
• Hormones
• Nutrition and dietetics
• Maintenance of pH, water and
electrolyte balance
• Cancer
• Immunochemistry
• Xenobiotics
22. Amino acids are the building blocks for
synthesis of proteins
Proteins form the structural framework
of tissues and perform a variety of
other functions in the form of enzymes,
hormones, receptors, antibodies etc
Chemistry of amino acids and proteins
23. Enzymes are the universal catalysts of
the living world
No reaction in living organisms can occur
at a significant rate without enzymes
Enzymes
24. With a few exceptions, all enzymes are
proteins
They have unique three-dimensional
structures suited to their catalytic
functions
25. Enzymes also play a crucial role in
metabolic regulation
One (or a few) key enzyme(s) regulate
a metabolic pathway
Rates of reactions are regulated by
altering the concentration or catalytic
activity of the key enzyme(s)
26. Many diseases can be diagnosed by
measuring the levels of some enzymes
in biological fluids e.g. plasma
Many inhibitors of enzymes are used as
drugs
Some enzymes themselves are used as
drugs
27. Carbohydrates and lipids are used
mainly as sources of energy
Carbohydrates constitute the largest
component of our daily diet
Chemistry of carbohydrates and lipids
28. Lipids constitute the major storage form
of energy
Some carbohydrates and lipids perform
structural roles as well
29. The chemical reactions the biomolecules
undergo in the body constitute metabolism
The process begins with the digestion of
complex biomolecules
This is followed by absorption of the
products of digestion
Metabolism of carbohydrates, lipids,
amino acids and proteins
31. Anabolism and catabolism occur by a
series of reactions
Each reaction series constitutes a
metabolic pathway
There are a number of pathways for
metabolism of carbohydrates, lipids and
amino acids
32. While studying metabolic pathways,
we should look at their:
• Tissue distribution
• Intracellular location
• Reactions
• Energetics
• Regulation
• Importance
• Disorders
33. Metabolic disorders occur due to a
block in some reaction of the pathway
The block occurs owing to a mutated,
dysfunctional enzyme
34. Energy is released during oxidation of
carbohydrates, lipids and amino acids
It is captured by oxidative phosphorylation
It is utilized in anabolic pathways and for
muscle contraction, active transport etc
Bio-energetics and oxidative
phosphorylation
35. Adenosine triphosphate (ATP) is the
universal currency of energy
ATP is formed during energy-yielding
(exergonic) reactions
ATP is utilized in energy-consuming
(endergonic) activities
36. Molecular biology is the study of nucleic
acids and their building blocks
Nucleic acids are deoxyribonucleic acid
(DNA) and ribonucleic acid (RNA)
Their building blocks are nucleotides
Molecular biology
37. DNA and RNA are known as information
molecules
Genetic information is present in DNA in
the form of genes
A gene possesses coded information
about amino acid sequence of a protein
38. An RNA transcript of gene carries
information from DNA to the ribosomes
Using this information, the protein is
synthesized on the ribosome
39. During cell division, DNA of the cell is
exactly replicated
The daughter cells acquire the genetic
information present in the parent cell
40. Study of molecular biology
includes processes like:
Replication (synthesis of DNA)
Transcription (synthesis of RNA)
Translation (synthesis of proteins)
Recombinant DNA technology
41. Recombinant DNA technology has led to
a revolution in molecular biology
Its study comprises the study of its tools,
techniques and applications
Recombinant DNA technology is finding
applications in all life sciences
42. Vitamins are a group of chemically
diverse organic compounds required in
minute quantities but essential for life
Many vitamins act as coenzymes,
essential for the activity of a number of
enzymes
Vitamins
43. Some vitamins are required for growth,
differentiation, vision etc
Deficient intake of most, and excessive
intake of some, vitamins produces
specific diseases
44. Study of vitamins covers their:
• Chemistry
• Functions
• Requirements
• Dietary sources
• Diseases resulting from deficient or
excessive intake
45. A number of minerals are essential for
human beings
Some are required in relatively large
quantities (macronutrients)
Others are required in minute quantities
(micronutrients)
Minerals
46. Minerals are required for:
• Formation of bones (Ca and P)
• Nerve conduction (Na and K)
• Formation of haemoglobin (Fe)
• Activity of enzymes (Cu, Zn, Se etc)
47. Study of minerals covers their:
• Functions
• Requirements
• Dietary sources
• Diseases resulting from deficient or
excessive intake
48. Hormones are mobile signal molecules
They carry signals from one organ,
tissue or cell to another
They are required for intercellular
communication and co-ordination
Hormones
49. Hormones help the organism to respond
to any change in internal or external
environment in a coordinated manner
Small changes in the concentrations of
hormones produce profound physio-
logical and biochemical effects
50. Under- or over-production of hormones
produces serious disorders
Diagnosis of these disorders usually
requires biochemical measurement of
hormone concentrations in blood
51. Water constitutes nearly two-thirds of
the body weight in an adult man
Water is the universal solvent of the
living world
It is the medium in which all biochemical
reactions occur
Maintenance of pH, water and
electrolyte balance
52. Small changes in water content, distri-
bution of electrolytes and pH of body
fluids can derange normal functioning
Such changes can occur in a variety of
diseases
Correction of the imbalance requires a
sound understanding of normal regulatory
mechanisms
53. We obtain all the nutrients we require,
viz. carbohydrates, lipids, proteins,
vitamins and minerals, from food
Malnutrition (under- and over-nutrition)
is common all over the world
Nutrition and dietetics
54. Diseases resulting from under-nutrition
afflict large sections of poor
Over-nutrition is the bane of the rich
Ignorance contributes significantly to
both
55. Correction of under-nutrition and over-
nutrition requires a sound knowledge of
principles of nutrition and dietetics
Dietary advice is required in some non-
nutritional diseases also
56. Cancer (malignancy) has emerged as a
leading cause of death worldwide
A number of physical, chemical and bio-
logical agents are known to cause cancer
Cancer
57. Molecular mechanisms that transform a
healthy cell into a cancer cell have eluded
us for a long time
Advances in molecular biology are now
revealing the interplay of anti-oncogenes,
proto-oncogenes and onco-genes
This complex interplay can transform a
normal cell into a cancer cell
58. We are exposed to a vast range of foreign
antigens that can cause disease
To protect us against these antigens, we
have a very competent immune system
The immune system comprises innate
immunity and adaptive immunity
Immunochemistry
59. A number of molecules are involved in
recognition and inactivation of antigens
Immunochemistry is the study of mole-
cules of immune recognition and the
mechanisms by which the foreign
antigens are dealt with
60. Apart from antigens, we are exposed to a
variety of foreign chemicals, known as
xenobiotics, that can cause toxicity
Through biochemistry, we understand the
mechanisms by which the xenobiotics are
detoxified and excreted
Xenobiotics
61. Study of human biochemistry, thus,
gives us insights into the molecular
basis of complex biological phenomena
Biochemistry is, therefore, described as
the chemical language of life
62. This chemical language helps us:
• In understanding the normal functioning
of the body at molecular level
• In unraveling the molecular basis of
diseases
• In diagnosing diseases by laboratory
investigations
• In treatment by providing enzymes,
enzyme inhibitors and gene therapy
