No – this is not an acronym for “Gentlemen Only, Ladies Forbidden” as some internet postings would like you to believe.
Golf, as we know it today, was invented in Scotland in 1552 at the famous St. Andrews course.
The medieval Dutch word “kolf” or “kolve” meant “club.” It is believed that word passed to the Scots, whose old Scots dialect transformed the word into “golve,” “gowl” or “gouf.”
This morphed into another Scottish word “golph”, and now the English word, “golf.”

New research reveals how…
Leprosy bacterium creates stem cells
The bacterium that causes leprosy spreads through the body by converting nerve cells into stem cells with migratory properties, according to research published in the journal
(red) taken from a leprosy skin lesion.
In a recent article by Toshihiro Masaki et al., the ability of
to transform mature Schwann cells into progenitor stem-like cells was discovered.
This bacterium, responsible for leprosy, is able to infect adult Schwann cells and reprogram them into a precursor state. Because
is an intracellular pathogen, it utilizes the plasticity of Schwann cells to spread. Once reprogrammed, these cells can disseminate through the body differentiating into other cell types while also recruiting macrophages, further spreading infection.
Research into the mechanisms behind this pathogen’s cellular hijacking technique could lead to a better understanding of cellular plasticity as well as provide a means of creating stable stem cells for disease research.
The Bacteriophage Comeback?
ould the use o
f bacteriophage be the next big thing in antimicrobial therapy?
Due to increasing resistance to antibiotics, there is an increasing demand to take a second look at novel therapies, such as using the bacteriophage against bacterial diseases. Bacteriophage therapy began in the 1930s in Eastern Europe and still continues today in Georgia.
The word bacteriophage literally means “to eat bacteria.”
It is a virus that exclusively attacks bacteria. Once the phage has entered the body, it attaches itself to the bacteria causing the infection, and shoots in its own DNA to make the bacteria start producing new bacteriophage. Within 30 minutes, up to 200 new phage are created, and in the process the bacteria die. Once the job is done, the phage automatically start to disappear.
What has long made antibiotics so appealing is the fact that they eliminate so many types of bacteria in one go. Phage are more complicated and specific: a certain type has to be found to combat each infection.
“But it’s this specificity which makes them so attractive,” says Ron Dixon, Head of the Department of Forensic and Biomedical Sciences at Lincoln University. “It will only kill the bacteria you want it to.”
And if the bacteria become resistant to the phage, as they have done to antibiotics, a new phage matched to the new bacteria can be developed. In order to inhibit resistance, a cocktail of phage would most likely be used in treatment.
There are no known side-effects, researchers stress, although there were significant numbers of deaths in the 1930s and 1940s mainly
due to a failure to understand the biology of phage, inaccurate diagnoses of patients in the first place and poor manufacturing procedures.
Nonetheless, few Western companies have ventured into the field of bacteriophage therapy. Nick Housby of
Limited in the UK – one firm which has – says this is because of the intellectual property rights surrounding the therapy, which has so long been used elsewhere. Phage are notoriously hard to patent, the process by which drug companies secure future profits.
Novolytics is currently working on a cream which they say could combat MRSA. Inserted into the nose, where MRSA bacteria frequently linger, it is hoped the cream could combat more than 15 strains of the condition.
This new therapy still needs to be subjected to two phases of clinical testing, and even if these are proved to be successful, it may take as many as five years for the cream to hit the market.
Teflaro – A New drug for MRSA
eftaroline is a unique broad-spectrum cephalosporin with novel
activity against a variety of community- and hospital-acquired pathogens, including methicillin-resistant
(MDRSP), and common (non-Extended-Spectrum Beta-Lactamase-producing) gram-negative bacteria. Ceftaroline was cleared for clinical use by the United States Food and Drug Administration in October 2010. The brand name is Teflaro, made by Forest Pharmaceuticals.
In December of 2010, Hardy Diagnostics became the first U.S. medical device manufacturer to offer
for susceptibility testing under the HardyDisk line. Moreover, since its FDA clearance, ceftaroline has yet to be offered for use on any commercial susceptibility test platform; thereby requiring clinical microbiology laboratories to perform traditional agar diffusion methods (Kirby-Bauer) to test clinical isolates for ceftaroline susceptibility.
Ceftaroline works by binding penicillin binding proteins (PBPs). In
, there are four naturally occurring PBPs (PBP1-4) and ceftaroline binds to all, with the highest affinity for PBP2a. PBP2a is a principal factor of broad-spectrum
-lactam resistance in MRSA isolates. PBP2a has a low affinity for
-lactams and, thus, provides transpeptid
ase activity to allow cell wall synthesis at
-lactam concentrations that inhibit the
-lactam-sensitive PBPs normally produced by
. Consequently, binding of ceftaroline to the PBP2a protein in S. aureus results in ceftaroline activity against MRS
A. Interpretive criteria and quality control ranges for ceftaroline can be found in the current edition of the CLSI M100: Performance Standards for Antimicrobial Susceptibility Testing document.

Should clinical labs
hire more MLT’s?
Currently the management of clinical laboratories find that they must continually cut costs and increase efficiency.
Some labs do this by utilizing more and more the services of Medical Laboratory Technicians (MLT), rather than hiring the more highly paid and extensively trained Clinical Laboratory Scientists (CLS). Is this a trend that should continue?
Should the post office have discontinued Saturday delivery service?
he Postal Service posted a $16 billion loss in 2012, that’s $40 million per day. The agency claims eliminating Saturday delivery will save $2 billion annually.
Therefore, the Postal Service announced that they would cease Saturday deliveries by August, after providing this service for 150 years. Packages, Express, and Priority mail will still be delivered on Saturdays.
The Postmaster General reminded everyone that the USPS takes no taxpayer dollars, and that the Post Office used to deliver mail twice a day during the week, and we all survived the end of that.
Was this a good thing?
