The small intestine is the part of the alimentary canal that is continuous with the stomach at the pyloric orifice and leads into the large intestine through the iliocaecal valve. It is the part where the chemical digestion of food is completed and most of the absorption of nutrients take place.
It extends from the ileum to the anus.
It reabsorbs water converting liquid chyme into semi solid stools.
It consists of the following parts: 1)Caecum and vermiformis appendix. 2)Ascending colon and hepatic flexure. 3) Transverse colon and splenic flexure 4)Descending colon 5)Sigmoid colon 6) Rectum and 7) Anal canal.
The proximal half as far as the splenic flexure – reabsorbs water and electrolytes from fluid chyme .
The distal colon beyond the splenic flexure-stores formed faeces until they are excreted.

Couples presenting to the infertility clinic- Do they really have infertility...Sujoy Dasgupta
Dr Sujoy Dasgupta presented the study on "Couples presenting to the infertility clinic- Do they really have infertility? – The unexplored stories of non-consummation" in the 13th Congress of the Asia Pacific Initiative on Reproduction (ASPIRE 2024) at Manila on 24 May, 2024.
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
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!

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

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. large intestine, also known as the large bowel or colon,
is the last part of the gastrointestinal tract and of the
digestive system
1.5 metres (5 ft) long,
1/5 of the whole length of the gastrointestinal tract
Sections of the colon are:
The ascending colon including the cecum and appendix
The transverse colon including the colic flexures and
transverse mesocolon
The descending colon
The sigmoid colon – the s-shaped region of the large
intestine
Rectum
Anal canal
4. Functions of large intestine
3 primary functions:
1. absorbing water and electrolytes,
2. producing and absorbing vitamins,
3. forming and propelling feces toward the
rectum for elimination. Convert the liquid
contents of the ileum into semisolid feces by
absorbing water, salts, and electrolytes. It
also stores and lubricates feces with mucus.
5. By the time indigestible materials have reached the
colon, most nutrients and up to 90% of the water
has been absorbed by the small intestine.
The role of the ascending colon is to absorb the
remaining water and other key nutrients from the
indigestible material, solidifying it to form stool.
The descending colon stores feces that will
eventually be emptied into the rectum.
The sigmoid colon contracts to increase the
pressure inside the colon, causing the stool to move
into the rectum.
The rectum holds the feces awaiting elimination by
defecation.
6.
7.
8. Is characterized by the following:
1. Teniae coli: three narrow bands of the outer
longitudinal muscular coat.
2. Sacculations or haustra: produced by the teniae,
which are slightly shorter than the gut.
3. Epiploic appendages: peritoneum-covered sacs of
fat, attached in rows along the teniae.
The taenia coli run the length of the large intestine.
Because the taenia coli are shorter than the large
bowel itself, the colon becomes sacculated, forming
the haustra of the colon which are the shelf-like
intraluminal projections
9.
10. • The pattern of
haustrations and
the apearance
of mucosa help
in flexible
endoscopy
examination.
• Clinician will be
able to identify
the part of colon.
11. CEACUM
Is the blind pouch of the large intestine. It
lies in the right iliac fossa and is usually
surrounded by peritoneum but has no
mesentery.
Length : 6-7.5cm
Width: 7.5cm
Has two openings
Ileal opening
Appendix opening
(gerlach`s valve)
12.
13. RELATION of CEACUM:
Anteriorly: Coils of small intestine, sometimes
part of the greater omentum, and the anterior
abdominal wall in the right iliac region
Posteriorly: The psoas and the iliacus muscles,
the femoral nerve, and the lateral cutaneous
nerve of the thigh. The appendix is commonly
found behind the cecum.
Medially: The appendix arises from the cecum
on its medial side.
14. ILEOCAECAL JUNCTION
Presents as transverse slit bounded by
upper and lower lips (projection of ileum
into cecum)
At the edge the lips fuses with each other
and become continuous with folds of
mucous membrane called FRENULA.
It act as physiological sphincter.
15. ASCENDING COLON
is the first of four sections of the large
intestine.
It is connected to the cecum below. The
ascending colon runs upwards through the
abdominal cavity toward the transverse
colon for approximately eight inches (15-
20 cm).
Covered anteriorly, on either side by
peritoneum.
16. RELATIONS:
ANTERIOR: anterior abdominal wall, hepatic
flexure of
colon, upper aspect of liver, gall
bladder and
Duodenum
POSTERIOR:
Muscles: iliacus, quadratus lumborum (medially)
and transversus abdominis (laterally).
Nerves: lateral cutaneous nerve of thigh, ilio
inguinal nerve, ilio hypogastric nerve
Artery: iliac branch of iliolumbar artery
19. Taking into account all ages and sexes, colon cancer occurs
here most often (41%).
20. TRANSVERSE COLON
The transverse colon is the part of the colon
from the hepatic flexure to the splenic flexure.
Is the longest subdivision.
The transverse colon hangs off the stomach,
attached to it by a large fold of peritoneum
called the greater omentum.
On the posterior side, the transverse colon is
connected to the posterior abdominal wall by a
mesentery known as the transverse
mesocolon.
21. The transverse colon is enclosed in
peritoneum, and is therefore mobile
RELATIONS:
Anteriorly: The greater omentum and the
anterior abdominal wall (umbilical and
hypogastric regions)
Posteriorly: The second part of the
duodenum, the head of the pancreas, and
the coils of the jejunum and the ileum
22.
23. DESCENDING COLON
The distal gut is the part of the colon from the
splenic flexure to the beginning of the sigmoid
colon.
Upper end of splenic flexure is anchored to
diaphragm by phrenico-colic ligament.
One function of the descending colon in the
digestive system is to store feces that will be
emptied into the rectum. It is retroperitoneal in
two-thirds of humans. In the other third, it has a
(usually short) mesentery.
Gut flora are very dense in this region.
Covered by peritoneum anteriorly, and on either
side.
24. RELATIONS:
POSTERIOR: left kidney, left transverses
abdominis, left quadratus lumborum, left
iliacus, psoas major muscles.
And similar nerves and vessels in other side.
In male: lower part of descending colon lies
over external iliac artery, femoral nerve,
genitofemoral nerve and testicular vessels.
ANTERIOR: Greater omentum, anterior
abdominal wall, coils of jejunum.
25. SIGMOID COLON
The sigmoid colon is the part of the
large intestine after the descending
colon and before the rectum.
It has its own mesentery. Which is v
shaped.
Completely enclose in peritoneum.
26. The name sigmoid means S-shaped. The
walls of the sigmoid colon are muscular, and
contract to increase the pressure inside the
colon, causing the stool to move into the
rectum.
Sigmoidoscopy is a common diagnostic
technique used to examine the sigmoid
colon.
32. Abdominal angina is abdominal pain after eating that occurs
in individuals with ongoing poor blood supply to their small
intestines known as chronic mesenteric ischemia.
when blood flow to the colon cannot increase enough to meet
visceral demands. This is similar to intermittent claudication in
peripheral vascular disease or angina pectoris in coronary
artery disease.
Atherosclerotic disease is the most common cause of
abdominal angina. In most people, it is occlusion of the
superior mesenteric artery that is responsible for the
abdominal symptoms.
Risk factors for superior mesenteric artery atherosclerosis
include smoking and hyperlipidemia
33.
34.
35. LYPHATIC DRAINAGE
from the ascending colon and proximal
two-thirds of the transverse colon is to the
colic lymph nodes and the superior
mesenteric lymph nodes, which drain into
the cisterna chyli.
The lymph from the distal one-third of the
transverse colon, the descending colon,
the sigmoid colon, and the upper rectum
drain into the inferior mesenteric and colic
lymph nodes.
