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!

Tom Selleck Health: A Comprehensive Look at the Iconic Actor’s Wellness Journeygreendigital
Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
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
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. 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
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
Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

3. ABRASION AND POLISHING AGENTS
I. INTRODUCTION
The finishing and polishing of restorative dental
materials are important steps in the fabrication of
clinically successful restorations.
The techniques employed for these procedures are
meant not only for removal of excess material but also
to smoothen rough surface.
Th e finishing of dental restorations prior to their
placement in the oral cavity has therefore three
benefits viz
4.
5. A) To promote oral hygiene – by resisting the accumulation of food
debris and pathogenic bacteria
B) Enhance oral function – a well polished surface aids in gliding
movement of the feed over occlusal surfaces and between
embrassure spaces (smooth restoration contacts minimise wear
rates on opposing and adjacent teeth. E.g.
materials like ceramics which contain phases harder than the teeth
enamel and dentine).
C) To improve esthetics.
The materials employed for finishing and polishing of dental
restorations are generally termed as Abrasives.
Thus an understanding of the characteristics / features with their
properties of these materials and the process of abrasion would aid
in improved clinical usage of these materials and techniques.
6. II. INDIVIDUAL CONSIDERATIONS
1. Abrasion
Craig has defined abrasion as :
“A process of wear whereby a hard rough surface (like a
sand paper disk) or hard irregular shaped particles (like
those in a abrasive slurry) plough grooves in a softer
material and cause materials from these grooves to be
removed from the surface”.
It has been stated by Skinner’s that abrasive wear could be a
“two body” or a “three body” process.
To understand this more specifically the terms viz. Wear,
Abrasive wear and Erosive wear need more understanding
7. Wear
– is a material removal process that can occur
whenever surfaces slide against each other. In dentistry
the outermost particle or the surface material of an
abrading instrument is referred to as Abrasive. The
material being
finished is termed as a SUBSTRATE.
8. II) Abrasive wear
: This could be of two types :
i. Two body wear – occurs when abrasive particles are
firmly bonded to the surface of the abrasive instrument
and no other and abrasive particles are used eg, a
diamond bur abrading a teeth.
ii. Three body wear – when the abrasive particles are free
to translate and rotate between two surfaces Eg, dental
prophylaxis pastes (between tooth and rubber cup)
9.
10. . Erosive wear
This is caused by hard particles impacting a substrate
surface, carried by either a stream of air or a stream of
liquid. Erosive wear should be differentiated from
chemical erosion more commonly known as acid
etching which involves acid and alkalis instead of the
hand particles to remove the substrate material.
Chemical erosion is employed to prepare teeth
surfaces for bonding purposes and not for finishing of
materials.
11. DESIGN OF ABRASIVE INSTRUMENTS
The abrasives employed could be one of the three
types, viz:
A. Abrasive Grits.
B. Bonded Abrasives.
C. Coated Abrasive Disks and Strips.
12. A. Abrasive Grits
Abrasive grits are derived from (abrasive) materials
that have been crushed and passed through series of
mesh screens to obtain different particle size ranges.
The grits are classified as –
1.COARSE,
3.MEDIUM FINE and
3.SUPER FINE according to
particle size ranges.
13.
14. B. Bonded Abrasives
These consists of abrasive particles incorporated
through a binder to form grinding tools.
The abrasive particles are bonded by 4 general
methods :
1. Sintering.
2. Vitreous bonding (Glass/Ceramic).
3. Resin bonding (usually phenolic resin.
4. Rubber bonding (usually silicone rubber).
15. 1. Sintering – Sintered abrasives are the
strongest variety since the abrasive particles
are fused together.
2. Vitreous Bonded – Are mixed with a
glassy or ceramic matrix material, cold
pressed to the instrument shape and fired to
fuse with the binder.
3. Resin Bonded – are cold or hot pressed
and then heated to cure the resin.
4. Rubber Bonded – made in a manner
which is similar to resin bonded.
16. C. Coated Abrasive Disks and Strips
These abrasives are supplied as disks and finishing
strips.
They are fabricated by securing abrasive particles to a
flexible backing material (heavy weight paper or
Mylar).
The disks are available in different diameters with thin
and very thin backings.
Moisture – resistant backings are advantageous as the
abrasive stiffness is not reduced by water degradation
17.
18.
19.
20.
21. ABRASIVE ACTION
Each fine abrasive particle thus presents as a sharp
edge which cuts through the surface similar to a
pointed chisel.
During this cutting process the shaving thus formed is
powdered and usually clogs the abrasive which thus
makes periodic cleaning of the abrasive necessary.
22. Abrasive Action On Metals
On abrading metallic restorations, the metallic grain
structure usually gets disoriented.
The more the abrasion the greater is the associated
disorientation.
Strain hardening of the abraded metal usually
accompanies the grain disorientation. (
23. Abrasive Action on Resins
The heat generated during this abrasion
partially relieves the stresses. If this heat
generated is excessive it may even relieve
stresses created during processing which leads
to warpage of the resin along with melting of
the surface of the resin.
The heat generated is directly proportional to
the efficiency of the abrasives.
24. TYPES OF ABRASIVES
I. According to Craig : The abrasives used can be classified
grouped as and :
A. Finishing Abrasives.
B. Polishing Abrasives.
C. Cleaning Abrasives.
A. Finishing Abrasives These are hard, coarse abrasives used
initially to develop desired contours and remove off gross
irregularities.
B. Polishing Abrasives These have a smaller particle size and
are less hard than abrasives used for finishing. They are used
for smoothening surfaces that are typically roughened by
finishing abrasives.
Cleansing Abrasives :These are soft abrasives with small
particle size and are intended to remove softer materials that
adhere to enamel or a restoration.
25. Skinner’s
Secondly Skinner’s has grouped the abrasives
employed in dentistry as follows:
A. Natural Abrasives.
B. Manufactured Abrasives.
26. Skinner’s classification
A. Natural Abrasive
1. Arkansas Stone
2. Chalk
3. Corundum
4. Diamond
5. Emery
6. Garnet
7. Pumice
8. Quartz
9. Sand
10.Tripoli 11.Zirconium silicate
12.Cuttle
13.Kleselguhr
Are generally preferred because of their more predictable physical properties.
B. Manufactured Abrasives
1. Silicon carbide
2. Aluminium oxide
3. Synthetic diamond
4. Rouge
5. Tin oxide

55. Superfinishing by the Magnetic Abrasive
Finishing Process
. Magnetic Abrasive Finishing (MAF) is a non-
conventional superfinishing process in which
magnetic abrasive particles interact with a magnetic
field in the finishing zone to remove materials to
achieve very high surface finishing and deburring
simultaneously.
56. SUMMARY & CONCLUSION
• Though a varied range of abrasive and polishing
agents have been described with relation to individual
dental materials, an ideal abrasive or a polishing agent
which would satisfy all polishing needs of the dental
materials, one would say is yet to be developed.
