Cardio and muscle endurance
Aerobic exercise (also known as cardio) is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. Aerobic literally means "relating to, involving, or requiring free oxygen", and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism. Generally, light-to-moderate intensity activities that are sufficiently supported by aerobic metabolism can be performed for extended periods of time

Types and structure of muscles
Muscle groups
Alterations in disease
Applications and implications in nursing
Muscle:
Muscle is a soft tissue and it is one of the 4 basic tissues, along with nervous tissue, epithelium, and connective tissue.
Muscles helps in movement, support and protection of internal organs.
Muscles can perform variety of functions
Muscles tissue is made up of cells called “MYOCYTES” or muscle fibers.
There are more than 600 muscles in the human body. A kind of elastic tissue makes up each muscle, which consists of thousands, or tens of thousands, of small muscle fibers.
Types of Muscles: There are 3 main types of muscles
Skeletal muscle
Cardiac muscle
Smooth muscle
Skeletal muscle:
These are having close relationship to the bone or skeleton, so called Skeletal muscles
It present in limbs and related body parts & It form about 40% of body weight.
Under microscope the skeletal muscles fibers shows prominent striations, so called “Striated Muscles” & It is also known as “Voluntary Muscles” (movements are under our control)
Structure of Skeletal muscle:
Muscle fibers shows transverse striations under light microscope so it is called “striated muscles”
The nucleus is located peripherally.
Each skeletal muscle is an organ that consists of numerous cells called muscle fibers.
Each muscle fibers surrounded by “ Endomysium”
Inside each skeletal muscle, muscle fibers are organized into bundles, called fascicles, each fascicle surrounded by perimysium.
The whole muscle is covered by “epimysium”
Each skeletal muscle has three layers: endomysium, perimysium and epimysium
Muscle fibers:
Muscle is composed of many long cylindrical-shaped elongated fibres called muscle fibers
Length varies according to the size and shape of the muscles.
The actual arrangement of the fibres depending on the function of the muscle.
Each muscle fibers covered by a membrane is called the sarcolemma.
The cytoplasm of a muscle fiber is called Sarcoplasm
In sarcoplasm there are many mitochondria and bundles of fine longitudinal thread like part is called “myofibrils”
Microscopic structure of myofibrils:
A myofibril (also known as a muscle fibril or sarcostyle) is a basic rod-like part of a muscle cell.
Muscles are composed of tubular cells called myocytes, known as muscle fibres in striated muscle, and these cells in turn contain many chains of myofibrils.
They are created during embryonic development in a process known as myogenesis.
Under light microscope each myofibril consist of 2 bands:
Light band or “I” Band and Dark band or “A” Band
The alternating pattern of these bands results in the striated appearance of skeletal muscle.
Light band or “I” Band:
The I-bands (isotropic in polarized light) appear light in color.
I band divided into 2 portions by a narrow dark line called “Z” line or “Z” Disc.
This “Z” line is formed by protein which does not permit the light.
The part in between 2 “Z” lines called “sarc
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.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

Pulmonary Thromboembolism - etilogy, types, medical- Surgical and nursing man...VarunMahajani
Disruption of blood supply to lung alveoli due to blockage of one or more pulmonary blood vessels is called as Pulmonary thromboembolism. In this presentation we will discuss its causes, types and its management in depth.
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.
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

• Each myofibril is 1-2µm in diameter and lies parallel to one another.
• Fibrils are divisible into filaments made up of contractile proteins :
myosin, actin, tropomyosin and troponin.
• Cytoplasm in the muscle fibers called sarcoplasm contains numerous
mitochondria (sarcosomes), smooth surface endoplasmic reticulum
(sarcoplasmic reticulum) and rich in glycogen.
6. ANATOMY & PHYSIOLOGY OF MUSCLES
• SARCOMERES are the smallest functional unit of skeletal muscle
and are composed of two protein filaments ; actin and myosin. Actin
is a thin filament and myosin is a thick filament, as shown on the
following diagram, and it is the interaction between these two
filaments that causes a muscle to contract and shorten.
