Amorous Sharks “Breaching” in the West Coast Waters of Scotland

by Ihor Cap

Some 21 shark species are known to swim the British coastal waters. However, when it comes to amorous basking sharks, recent studies have shown they tend to swim the shores of Scotland four times more than the UK waters. They slowly surf the west coast shores in search of food and a mate, especially around the outer Firth of Clyde. Other recently confirmed hotspots are located in Gunna Sound, between Coll and Tiree, and nearby the islet of Hyskeir, southwest of Canna. Come summer time and sharks as long as 33 feet (10 meters) ‘bask’ the surface of the warm waters feeding on plankton with their mouths wide open. A single ‘basker’ filter’s as much as 1.5 million litres (330,000 gallons) of water through its gills. This dark slaty grey to black fish is sometimes mistaken for a second fish following the other since both the dorsal and tail fins stick out of the water at the same time.

Jet-skiers, speedboats and other boaters must be especially careful this time of year not just because the sharks are feeding along the surface but also because this is their mating season. Basking sharks are loners, but come courting season and a hundred of them can appear in these plentiful waters. What makes basking sharks unusual around this time is their courtship behavior. The nose of one love struck shark follows the tail of the other shark or they may swim next to each other. Sometimes, they lunge vertically out of the water also known as “breaching.” Being the second largest fish in the world, it is easy to see why they are often mistaken for whales.

Little is known about these creatures and their behavior. Recent evidence shows that one shark can give birth to as many as six young live ones. Also, they take a long time to mature so the Scottish government has taken measures to protect them, especially around the identified hotspot areas.

Wealth and Health of 200 Countries Over Last 200 Years in 4 Minutes Flat

by Ihor Cap
What you will see is here is one amazing video that is a must see for everyone who likes or hates statistics. However, this story is not about statistics or numbers per se. Rather, it is a video story about the health and wealth of 200 countries in the world over the last 200 years and beyond in just 4 minutes flat. How is it done? A Swedish professor and super star of sorts with the locals, Hans Rosling, teaches global health and uses visualization as part of his work to communicate the wealth and health of countries by plotting 120,000 numbers and displaying them on an animated correlation chart which appears before him like a hologram.
He is the only individual that I know that communicates this historical progression of life expectancy against wealth for every country since 1810 in the most enjoyable way anyone can think of. In short, Professor Hans illustrates a world far different from what most of us imagine. The facts speak for themselves in this spectacular video of human evolution, but Professor Hans communicates this information in a way everyone understands. Now, sit back and enjoy the show.

QUICK PSA REFERENCE RANGE CHART FOR OBTAINED BLOODTEST VALUES

By Ihor Cap


Digital Rectal Exam

Sooner or later, men over 50 will or should regularly receive annual Prostate Specific Antigen (PSA) screening tests for prostate cancer.   Depending on your ethnic and racial backgrounds or family history these tests may even begin earlier. In any case, these screening tests may include but are not limited to a PSA test, a rectal examination, a urinalysis with micro to assess the kidney and urine for urinary tract infection or Uroflowmetry (aka Uroflow test) for assessing related voiding dysfunction.  It’s a humbling experience at least for a minute or so, but most of all PSA test receivers just want to know what the PSA results mean. This article addresses just that. It assembles a range of references from the health and medical literature on this topic and constructs a ready to use quick reference chart for that purpose. Test screening scores received from your Doctor’s office can be compared against the range of indices provided in this chart when you get home. The reading list at the end of this article also provides the corresponding hypertext link for the obtained indices. The hypertext links in and of themselves also make for a useful reading list to individuals who know nothing about this topic but need to satisfy their appetites for more information in this area.  As such, it is hoped that future scheduled visits and discussions with your Doctor will be more fruitful than the previous ones.
PSA Reference Range and Cancer Probability Chart for Blood Test

CHEMISTRY	LOWER LIMIT NORMAL REFERENCE RANGE	HIGHER LIMIT NORMAL REFERENCE RANGE	SUSPISCIOUS REFERENCE RANGE	HIGHLY SUSPISCIOUS REFERENCE RANGE	UNIT
PSA (Total)	< 2.6	2.6 to 4	4  to 10	>10	ng/mL
CANCER PROBABILITY RANGE	0% to 19% chance	20% chance	25% to 45% chance	>67% chance

NOTE: PSA Total values that fall below 4.0 nanograms per mililiter of blood (ng/ml) are generally considered “normal” although some physicians propose even stricter ng/ml values of 2.5 or less.  This latter value may be particularly relevant to people that tend to be more predisposed to these conditions. While the debate in the literature continues about setting even more stringent lower limit values for the safe or normal zones, there is little or no argument about the seriousness of the negative meaning of ng/ml values of 10.0 and more. However, as one of the articles in the reading list below tells us, there is more to all of this than just interpreting the PSA scores. One has to also consider many other interrelated factors to make a conclusive determination. A Free PSA score, a Free/Total PSA  value, PSA velocity, PSA density, age of the person, race, nutrition, and even sexual relations prior to blood test amongst them.
