Nanotechnology ("nanotech") is manipulation of matter on an atomic, molecular, and supramolecular scale. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter which occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size.

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
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.
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

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

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.

3. Nanotechnology is a field which deals with materials and systems having at
least one dimension in the range of 1-100 nanometer(1nm=10-9
).
•Study of control of matter on an atomic and molecular scale.
•The prefix “nano” is a Greek word for “dwarf”
•One nanometer (nm) is equal to one-billionth of a meter

7. Two main approaches are used in
nanotechnology:
1.Bottom up approach (simple to complex)
•Materials and devices are built from molecular
components which assemble themselves
chemically by principles of molecular recognition.
• Arrangement is favored due to non-covalent
intermolecular forces.
•DNA nanotechnology utilizes the specificity of
Watson Crick base pairing to construct well defined
structures out of DNA and other nucleic acids
8. 2.Top-down approach
• Nano-objects are constructed from larger entities
without atomic-level control .
•A number of physical phenomena become
pronounced as the size of the system decreases
•Include statistical mechanical effects, as well as
quantum mechanical effects.
•Solid state techniques can also be used to create
devices known as NEMS
9. Nanotechnology categorized as:
Bionanotechnology - deals with interfacing functional biomolecules with available
devices for development of devices with higher performance in terms of selectivity,
sensitivity and economics.
Nanoelectronics - deals with miniaturization of present submicron semiconductor
technology with feature size below 10nm.
Nanomaterials - take advantage of entirely different chemical, physical, optical
and electronic properties of nanoparticles than bulk material.
10.
11. Medical Nanotechnology
Nanomedicine - application of nanotechnology in medicine, including to cure
diseases and repair damaged tissues such as bone, muscle, and nerve
Key goals for nanomedicine
•To develop cure for traditionally incurable diseases (e.g. Cancer) through the
utilisation of nanotechnology
•To provide more effective cure with fewer side effects by means of targeted
drug delivery systems
13. Therapeutic
•Delivering medication to the exact location
•Killing of bacteria, viruses & cancer cells
•Repair of damaged tissues
•Oxygen transport
•Skin and dental care
•Augmentation of immune system
•Treatment of Atherosclerosis
14. Diagnostic nanotechnology
Nanoparticles possess certain size-dependent properties,
particularly with respect to optical and magnetic parameters,
that can be manipulated to achieve a detectable signal .
The primary event in most nanoparticle-based assays is the
binding of a nanoparticle label or probe to the target
biomolecule that will produce a measurable signal
characteristic of the target biomolecules.
A variety of probes have been used for this
purpose, including QDs, nanoshells,
and metal nanoparticles
15. Quantum Dots
QDs are semiconductor nanocrystals (2–8 nm) , characterized
by strong light absorbance, that can be used as fluorescent
labels for biomolecules.
Structure
Semiconductor nanocrystals typically composed of a core
semiconductor enclosed in a shell of another semiconductor
with a larger spectral band-gap; a third silica shell can be
added for water solubility
Applications
Multiplexed diagnostics; immunoassays; immunohistochemical
assays; neurotransmitter detection; cellular imaging
Toxicity
Risk of leakage of toxic core semiconductor materials into host
system or into environment on disposal
16. Schematic diagram of a multiplex QD-based assay.
•Multiple antigens (Ag) can be labeled by use of primary antibodies
(Ab)conjugated to QDs with different sizes.
•One antibody may be biotinylated and detected with a streptavidin-coated
QD.
•On excitation, QDs will have different emission maxima based on their sizes.
17. Cantilevers
.
Typical AFM setup
A micro fabricated cantilever with a sharp tip is
deflected by features on a sample surface, much
like in a phonograph but on a much smaller scale.
A laser beam reflects off the backside of the
cantilever into a set of photo detectors, allowing the
deflection to be measured and assembled into an
image of the surface
Cantilevers
Small beams –function by means of
nanomechanical deflections
cantilever arrays can detect
molecular targets without the targets
being labeled.
Structure
Micro machined silicon cantilevers
similar to those used in atomic force
microscope.
18. •DNA detection by hybridization
•PSA detection
•Salmonella enterica
Cardiac troponins
Toxicity
No particular toxicity concerns
Applications
•Protein and DNA detection and
quantification
19. Gold Nanoparticles
-are associated colloids (3 to 100 nm)
- rather stable and whose properties can be easily tailored
by chemically modifying their surfaces.
Structure
Gold nanoshells consist of concenteric sphere nanoparticles
with a dielectric core (gold sulphide or silica) surrounded with
a thin gold shell
Applications
Immunoassays;detection of infectious agents by dna
hybridisation
Toxicity
No particular
20.
21.
22. Magnetic nanoparticles
•Label choice is made so that its interaction with the
analyte gives a magnetic signal.
•Detection of label is done by magnetometer
•High sensitivity - detect subtle modifications in
magnetic character.
• Ability to detect circulating cancer cells and
microorganisms
23. Nano Barcodes
•Sequential electrochemical deposition of metal ions to give
submicrometer metallic barcodes whose differential reflectivity
can lead to identification of the unique striping patterns by light
microscopy
•Used for multiplexed protein assays and single-nucleotide
variation (SNP)mapping;
• Does not interfere with use of fluorescence labeling
24. Nanowires and nanotubes
•Similar to other nanoparticles, e.g., gold and QDs, but are
characterized by having different shapes, thus allowing for
different interactions with different entities and more
unique signals
•Can be associated with almost any chemical or biological
recognition system;
• allow real-time detection;
•analyte-independent;
•suitable for the use; in vivo diagnostics
Applications in nanodevices
•Nanoscale sensors
•Solar cells
•Transistors,diodes,lasers
25. Nanochip
• employs the power of an electronic current that
separates DNA probes to specific sites on the array
based on charge and size.
• Once these probes are on specific sites of the nanochip,
the test sample (blood) can then be analyzed for target
DNA sequences by hybridization with these probes.
•DNA molecules that hybridize with target DNA
sequences fluoresce,
detected and relayed back to an onboard system through
platinum wiring that is present within the chip.
•Detects within minutes(E.coli-4mins)
26. Microfluidics(lab on a chip)
•Composed of microfabricated fluidic channels, heaters, temperature sensors,
electrophoretic chambers, and fluorescence detectors to analyze nanoliter-size
DNA samples.
•DNA sample is completely unknown
• Combination of numerous processes of DNA analysis are combined on a
single chip( single glass and silicon substrate.)
27. •Capable of measuring aqueous reagent and DNA-containing solutions,
mixing the solutions together,
• Amplifying or digesting the DNA to form discrete products,
• And then separating and detecting those products
Example of an
integrated nanoliter
device. The fluid
substrate moves from
one chamber to the
next for processing by
delicate air pressure
controls.
28. MEMS-microelectromechanical systems
•Allow both electronic circuits and mechanical devices to be manufactured
on a silicon chip,
•MEMS do not require reagents or a fluidity based substrate to react upon.
•Primarily used in drug-delivery systems
•Swallowed capsule technology pills that allow
doctors to visualize GI bleeding
A camera the size of a pill
that contains metal oxide

29. Nanorobots
•Future nanodevices for maintaining and protecting human
body against pathogens
•Diameter of 0.5-3 microns
•Will be constructed out of parts with dimensions in range
of 1-100nm
•Powering of nanorobots can be done by metabolising
local glucose and oxygen for energy
•Will have simple onboard computers capable of
performing around 1000 or fewer computations per
second
•Will distinguish between different cell types by checking
their surface antigens
