Surgery for erectile dysfunction. Implantable devices, known as prostheses, can cause erections in many men with impotence. Malleable implants usually consist of paired rods, which are inserted surgically into the corpora cavernosa, the twin chambers running the length of the penis. The user manually adjusts the position of the penis and, therefore, the rods. Adjustment does not affect the width or length of the penis. cialis online scams cheap cialis online cialis online bestellen schweiz cialis online When there is angina or heart failure, the doctor may need to determine whether the heart has enough reserve to safely carry out the work necessary for sexual activity by performing cardiac treadmill stress testing. The Latin term impotentia coeundi describes simple inability to insert the penis into the vagina. It is now mostly replaced by more precise terms. The study of erectile dysfunction within medicine is covered by andrology, a sub-field within urology. Besides treating the underlying causes such as potassium deficiency or arsenic contamination of drinking water, the first line treatment of erectile dysfunction consists of a trial of PDE5 inhibitor drugs (the first of which was sildenafil or Viagra). In some cases, treatment can involve prostaglandin tablets in the urethra, injections into the penis, a penile prosthesis, a penis pump or vascular reconstructive surgery. Drug therapy for erectile dysfunction: In a small number of cases, people who have taken sildenafil have complained of headaches, flushing and stomach-ache. It can also cause some visual problems, including an increased sensitivity to light, blurred vision or an inability to tell the difference between blue and green. Men who are already taking medicines that contain nitrates, such as nitro-glycerine (usually for angina or heart disease), are strongly advised not to use Viagra as this is dangerous and may result in a heart attack. Other similar drugs are tadalafil (‘Cialis’)and vardenafil (‘Levitra’).

Espeleóloga do NEUA descobre novo troglóbio no carso Algarvio

Um novo género e uma nova espécie de tisanuro (Arthropoda: Insecta: Zygentoma: Nicoletiidae) de nome científico Squamatinia algharbica. Vulgarmente conhecidos como ‘peixinhos-de-prata’ou ‘traças-dos-livros’, este é o maior tisanuro cavernícola da Europa e o segundo maior do mundo, apenas ultrapassado por uma espécie cavernícola de Cuba.

Este animal é endémico do meio subterrâneo do Algarve e foi encontrado em grutas pela bióloga e espeleóloga Ana Sofia Reboleira (DBio, CESAM/NEUA), no âmbito do seu doutoramento sobre fauna cavernícola de Portugal.

Trata-se de um troglóbio típico, sem estruturas oculares, despigmentado, com o corpo estilizado e os apêndices extremamente desenvolvidos e que não sobrevive à superfície. É uma relíquia biogeográfica, que terá sobrevivido a vários episódios de alterações climáticas, refugiado no meio subterrâneo do maciço algarvio. Este animal partilha habitat com o pseudoescorpião gigante Titanobochica magna e o dipluro Litocampa mendesi, ambos descritos em 2010.


O NEUA apoiou os trabalhos bioespeleológicos que originaram esta descoberta.
