Viagra gives plants a lift

Nitric oxide, the chemical at the heart of the drug's success, could work wonders on the food and flower industries, writes Paul SimonsHe had a hunch that Viagra might work the same magic on plants so he put some into a vase of cut flowers and found they stayed fresh and perky for up to a week longer than usual. Just 2% of the dose needed to treat a bout of male impotence brought a new lease of life to roses, carnations and African daisies."The flowers looked much fresher, their colour remained longer, and they were also much more turgid," reported Leshem. No one is suggesting spraying Viagra over plants to stave off wilt: there could be embarrassing side-effects and the cost would be prohibitive, but there might be cheaper and safer alternatives.Continue reading...

Conclusion In 1919 George A. Soper1 wrote that the deadly Spanish Flu pandemic that swept around the earth was without any precedents, and that there had been no such catastrophe ‘so sudden, so devastating and so universal’. He remarked that, “The most astonishing thing about the pandemic was the complete mystery which surrounded it. Nobody seemed to know what the disease was, where it came from or how to stop it. Anxious minds are inquiring today whether another wave of it will come again”. With close to 3 million positive cases and around 0.2 million deaths worldwide, the coronavirus has compelle...

Erectile dysfunction recognition dates back to Ancient Greece, praying to Aphrodite. Even the Bible mentions retribution for adultery by punishing Abimelech with impotence.1 Hippocrates described erectile dysfunction as an imbalance of humors. Still, it was Leonardo Da Vinci (1452 –1519) who first clarified these classical descriptions by observing the requirement of blood flow from executed men's resulting erections after hanging.2 However, the teachings of Hippocrates pervaded Western medical thought until well into the Renaissance.

PasquiniROME, Apr 9 2020 (IPS-Partners) Behind the Tiburtina Station, in the East of Rome, with just a small covered area protecting from the inclemency of the weather, sleeping close to each other is the only way to stay warm. A boy of Ivorian origin is alone, far from everyone, in the centre of the sidewalk, exposed to a freezing wind. ‘He told me he preferred to die of cold than to get infected, because he was very scared and he knew that it was not safe for him to be close to the others’, Dr. Antonella Torchiaro told Degrees of Latitude. She is a physician o...

Gram -ve bacteria have recently been found to induce O-antigen-specific IgG2 and IgA ‘inhibitory’ antibodies (iAb) in the host which are not only impotent but block complement-mediated killing. Our group has demonstrated the clinical benefit of plasmapheresis in patients infected with Pseudomonas aeruginosa (Psa) strains which have deployed this virulence factor. Here we assesse d the prevalence and clinical impact of iAb in a large lung transplant cohort.

ABSTRACT Introduction: Androgen deprivation therapy (ADT) is the mainstay of therapy for advanced prostate cancer. Studies addressing the efficacy of different depot formulations of long acting luteinizing hormone releasing hormone agonists in the Brazilian population are lacking. We aimed to compare the efficacy of three schedules of leuprolide acetate in lowering PSA in a real world population. Materials and Methods: We reviewed the medical records of patients with prostate cancer seen at our institution between January 2007 and July 2018. We analyzed patients treated with long-acting leuprolide acetate and grouped these...

Stress caused by uncertainty can be paralyzing. The information we are getting about the coronavirus seems to be changing by the hour — creating unprecedented uncertainty. There is a good reason your nerves are jangle, or you are feeling unsettled or anxious. Uncertainty is perceived as unsafe and potentially painful. Whether the situation is predictably positive or predictably negative, your brain prefers something familiar to something unfamiliar. Under stress, our brains depend on instinct rather than rational thought because the part of the brain responsible for critical thinking is busy dealing with the psycholo...

By ANISH KOKA, MD As the globe faces a novel, highly transmissible, lethal virus, I am most struck by a medicine cabinet that is embarrassingly empty for doctors in this battle.  This means much of the debate centers on mitigation of spread of the virus.  Tempers flare over discussions on travel bans, social distancing, and self quarantines, yet the inescapable fact remains that the medical community can do little more than support the varying fractions of patients who progress from mild to severe and life threatening disease.  This isn’t meant to minimize the massive efforts brought to bear to keep...

Reggie Dye went 15 years without seeing a physician, in part because he had always been incredibly healthy. He regularly does high-intensity worksouts, enjoys hiking, golf, and can't remember the last time he even had a cold. But a preventative health evaluation incentive program his company offered in 2016 taught him that even the healthiest individuals are not immune to prostate cancer. After two prostate-specific antigen (PSA) screening tests, followed by additional testing, Dye was diagnosed with localized prostate cancer. At first, he was given the choice of active surveillance, als...
