Os cachorros podem empatizar com humanos mais do que qualquer outro animal, incluindo outros humanos.Dogs may empathize with humans more than any other animal, including humans themselves.During one experimental condition, the people hummed in a weird way. For that one, the scientists were trying to see if unusual behavior itself could trigger canine concern. The people also talked and pretended to cry.The majority of the dogs comforted the person, owner or not, when that individual was pretending to cry. The dogs acted submissive as they nuzzled and licked the person, the canine version of “there there.

Cytoplasmic inclusions found in neurons containing the rabies virus. In this picture, there’s only one inclusion seen as a purplish dot in the right part of the neuron. The blue cells around are (probably) lymphocytes.Posted on September 4, 2012 at 4:17 PM
Bullet shaped virion. Rhabdo (Greek) means rod.
The viral RNA and N (= nucleo) protein form the nucleocapsid, which is connected to RNA polimerase (L for large) by phosphoprotein P. RNA polimerase transcribes the viral genes. The virion also has a lipoprotein membrane, with glycoprotein G sticking out, important for binding to cells. There’s also matrix protein M under the lipoprotein membrane.
Rabies virus, from the genus Lyssavirus causes rabies (obviously).Posted on September 4, 2012 at 3:51 PM
Typhoid Mary (Mary Mallon) was a cook in the US in the 20th century. Unfortunately, she was also a carrier of Salmonella typhi, the pathogen that causes typhoid fever. Being an asymptomatic carrier she didn’t show any signs of infection, she was seemingly healthy. However, she continuously shed the bacteria in urine and feces, allowing her to spread the infection by fecal-oral route, i.e. through the food she cooked if she didn’t pay much attention to hygiene. She did manage to spread the infection and some of her ”victims” even died.

Luckily, today we have antibiotics, so scarlet fever can be cured rather successfully. Streptococcus pyogenes can be treated with penicillin and macrolides, and is one of the rare bacteria that are fairly non resistant to them, although there have been reports of strains which are resistant to macrolide antibiotics.Posted on September 3, 2012 at 2:30 PM
is caused by streptococcus pyogenes. Sore throats can also be caused by viruses, but the difference between the two is the production of pus which is seen in the bacterial infection. If this bacterium produces an exotoxin (called erythrogenic toxin) it can cause a skin rash, accompanied by a sore throat and fever, (like the ”usual” strep throat). In that case it’s called scarlet fever.
The red spots on the soft palate in the picture above are called Forchmeimer spots, and are actually petechiae caused by the exotoxin. They can also be seen in measles and rubella.Posted on September 3, 2012 at 2:18 PM
Repair of ventricular septal defect
Henry De’Ath, Royal London Hospital
This photograph shows the repair of a traumatic ventricular septal defect (VSD). A VSD is a hole between the right and left ventricles of the heart, and is usually seen as a congenital condition, known as a ‘hole in the heart’. This picture was taken in theatre to document the unusual injury and its subsequent repair.

Tache noire is one of the important postmortem changes seen in the eye after death.
If the eyes remain open after death, the areas of the sclera exposed to the air dry out, which results in a first yellowish, then brownish-blackish band like discoloration zone called TACHE NOIRE.
It is generally seen 3 to 7 to hours after death and can disappear altogether a day or so later.
