Actinomyces israelii

CGD is characterized by recurrent life-threatening infections and excessive granuloma formation, involving the lungs, skin, soft tissues, and reticuloendothelial system. Recurrent deep-seated infections with catalase-positive organisms such as Staphylococcus aureus or Aspergillus fumigatus are typical.

However, catalase-dependent virulence is not the complete story, because most pathogens in general are catalase-positive, but only a small subset is encountered in CGD patients: Staphylococcus aureus, Serratia marcescens, Burkholderia cepacia, Nocardiaspp., and Aspergillus species. The frequency of infection with catalase negative organisms in CGD is extremely low. CGD, 5% of abscesses yielded streptococci but the number that were in pure culture is unknown.

Nocardia infections are almost exclusively seen in immunocompromised patients and are important causes of infection in patients with CGD. Nocardia species have been implicated as the causes of pulmonary, cutaneous, ocular, and dissemi…

Dark War of Actium

On the Ionian Seas, just off of the shores of Greece, the navies of the fledgeling empire that Rome was becoming and the kingdom of Egypt met to decide the outcome of a political dispute. That dispute had its seeds planted first during the campaigns in Asia Minor. They were then cultivated with the assassination and began to sprout in Asia Minor. The ultimate prize for the victor at Actium would be dominion of the Roman Empire.

While in Asia Minor, He led an army of the Roman Republic to track down the Roman general. Rome was in the midst of a civil war for power of the Roman legions. After his victories in Europe, The general was forced to flee towards the edges of the Republic. Upon arrival in Egypt, which was in the middle of its own civil war between the brothers, The general was killed by agents of the empress as she sought Roman aid in her battles. Her stratagem almost worked. While he was appreciative of her dispatching the general, it was not until she had seduced him that he c…

Actaeon's Tragic End

Deep in the woods, Actaeon is hunting deer with a group of his friends and a large pack of dogs. By noon, the sun is beating down on them, and the group is getting tired from hunting all morning. Actaeon decides to give everyone a break and tells his bros to that they'll resume hunting tomorrow morning. Meanwhile, the goddess Artemis is also hot and exhausted from hunting. She decides to take a spa day (although she'd probably kill us for saying that) and goes to her secret grove to wash up. Artemis undresses and takes a refreshing bath with the help of her wood nymph handmaidens. They brush her hair, pour water over her, and generally desweatify her.

Looking for a place to cool off, Actaeon wanders deep into the woods and stumbles upon the bathing goddess. Oops. Or not so oops. While some versions of the story say that he came across Artemis by mistake, others say that it was totally intentional—and that he even suggested that they sleep together.
Either way, when they see Acta…

An Act Of War

When bombers unleashed a devastating surprise attack on a naval base in, killing 2,402 and wounding 1,282 more. President called it “a date which will live in infamy” as he asked for a declaration of war.

Fifty years later, another surprise attack killed almost 3,000 people when terrorists flew two jetliners into the twin towers.

We all know what an act of war looks like on land or sea, and by evoking two of the most searing attacks in our modern history, He was trying to raise a sense of urgency about the threat in a new domain made of bits and bytes zinging between servers around the world.

But what does an act of war look like in cyberspace?

And perhaps more important, what does the government do when cyberattacks fall short of that — assuming it can identify the perpetrators in the first place?

What about something like a virus that wiped data from 30,000 computers, affecting business operations for two weeks? He called that assault, along with a similar strike, “probably the most des…

Living With Acromegaly

WHEN retired dental nurse Alexia met an old friend recently, all she got was: “Why do you look so different now?”

If you’re meeting Alexia for the first time, nothing about her will strike you as out of the ordinary. It is only after she shows you a picture of her old self, that you might be inclined to think she’s someone else altogether.

As compared to the attractive woman staring back from the photo, Alexia's nose is wider; her jaw, enlarged. “Initially, I wasn’t very comfortable about being seen in public. I stopped taking photographs, because I could not bear to see the ‘changed’ me,” she says.

She was diagnosed with acromegaly – after years of consulting the wrong specialists. “I was having problems with my occlusion (contact between the upper and lower teeth) – I couldn’t bite properly. I saw a few dental specialists and even an orthodontist. I said to them: ‘I think something is wrong with my jaw’, but none of them knew what was happening to me. I was referred to many differe…

Father of Acarology

In Acarology, Latreille was interested by classification and higher taxa categories. He described a lot of Hydrachnellae, genera and species of all Eylais. He Devoted himself to natural history, specialised on terrestrial arthropods and discovered and described a lot of New Species, especially mites. In Acarology, his contribution was modest as he described only a species species of Ixodes. Because it was difficult to identify Because it was difficult to identify flies especially the flies especially the Cyclorrhapha Cyclorrhapha – – Calyptratae Calyptratae, the existing descriptions , the existing descriptions of which were poor, and because he of which were poor, and because he had only very few contacts many of had only very few contacts many of the new species of the new species of Diptera Diptera he described were already named. Very many of his generic generic and species species names survive, especially in the names survive, especially in the Cyclorrhapha Cyclorrhapha, his myo…

Acrolein Poisoning Shorten His Life

Acrolein enters the air from the burning of fossil fuels and tobacco smoke. It forms when animal and vegetable fats are heated. It is also a by-product of fires and can be toxic to firefighters. Acrolein is mostly used to make acrylic acid. It is also used to control plant and algae growth in irrigation canals. Acrolein kills or controls microorganisms and bacteria in oil wells, liquid hydrocarbon fuels, cooling-water towers and water treatment ponds. In papermaking, acrolein is used to control slime.

Breathing low levels of acrolein can irritate the nose, nasal cavity, windpipe and voice box. Fluid build up in the lungs can also occur from breathing acrolein. In cases of severe breathing exposure, death could occur from damage to the lungs and respiratory system. Eating or drinking acrolein can cause burns to the lips, mouth, throat, esophagus and stomach. You could throw up or have diarrhea. If acrolein gets in the eyes, it can cause severe irritation or burns. Exposure to acrolein v…
