TORONTO – With cases of flu continuing to rise in Canada, there’s likely a whole lot of “achooing” going on across the country. But ear, nose and throat doctors advise against trying to stifle those sneezes, as such suppression can in rare cases lead to injuries.One of the most serious is detailed in the journal BMJ Case Reports, published online Monday, in which a 34-year-old man from the United Kingdom ruptured his throat after pinching his nose and clamping his mouth shut to contain a forceful sneeze.The post-sneeze trauma left the man in pain and barely able to speak or swallow.When emergency care doctors examined the patient, they heard popping and crackling sounds extending from his neck to his rib cage — a sign that air bubbles had found their way into the tissue and muscles of his chest, the authors at the University Hospitals of Leicester NHS Trust write.The unidentified man, who was treated in hospital for a week, was advised against repeating such a “dangerous manoeuvre” in the future.“This tear in the throat is incredibly unusual,” said Dr. Douglas Chepeha, an ear, nose and throat (ENT) specialist at University Health Network in Toronto. “In my career, I’ve never seen anything like that.”However, he said there are a number of other injuries that could occur from trying to block a sneeze, though they, too, are relatively rare.Impeding the release of air from the nose and mouth during a sneeze could rapidly increase the pressure in the lungs, forcing the air out and trapping it in the chest between the lungs — a condition known as pseudomediastinum.A suppressed sneeze could also build up pressure in the middle ear, though Chepeha said bursting an eardrum that way is very rare. (To understand the effect, think of popping one’s ears in a descending airplane by breathing out against pinched nostrils to restore hearing.)In the BMJ case report, authors point out that thwarting a sneeze — the body’s attempt to eliminate such irritants as mucus or allergens in the nose — could conceivably rupture an undetected aneurysm, or ballooning blood vessel, in the brain.And it could also cause small surface blood vessels in the eyes and other areas of the head and neck to burst due to built-up pressure, Chepeha said.“In your nose itself, you can burst a blood vessel and get a bleeding nose.”Even without being impeded, sneezing has been known to cause injuries, said Dr. Eric Monteiro, an ENT at Mount Sinai Hospital in Toronto.“There have been reports of elderly women who develop brittle bones in osteoporosis, developing vertebral compression fractures as a result of sneezing,” he said Monday in an interview.Some Major League Baseball players have hurt themselves by sneezing, including Toronto Blue Jay Kevin Pillar, who ended up on the 10-day disabled list when a sneeze led to an oblique muscle strain during the 2015 pre-season.So is there a right way to sneeze?Not really, said Monteiro, explaining that sneezing is an involuntary protective reflex that can’t necessarily be controlled.“But I think there is a wrong way, which is trying to plug your nose and close your mouth, which is just generally not recommended because you inhibit the natural process,” he said.“And if you do that, you’re potentially setting yourself up for an injury, notwithstanding the fact that they’re rare.”While doctors may discourage people from stifling a sneeze — whether it’s a dainty achoo or a big honk — Chepeha said people should deliver it into their inner elbows to prevent spreading the flu virus or other air-borne bugs.“Of course you have to cover your mouth, and the absolute best way is to cough or sneeze into your sleeve.”– Follow @SherylUbelacker on Twitter.
20 Photos Some people are still trying to predict when the trailer will arrive, despite our previous failures for the Super Bowl and Oscars. Film and TV editor Emmy Griffiths crunched the numbers and thinks we’ll get the trailer before the end of this week. “I have no means been obsessively checking old correlations between GoT trailers and premiere dates to reach this conclusion,” she jokes. Game of Thrones HBO 0 Cookies are coming. pic.twitter.com/aTPjU4l4gS— Oreo Cookie (@Oreo) February 23, 2019 Enlarge ImageCan we get a trailer already? Helen Sloane/HBO We could hear it, like dragon wings pounding the air. It was time. First we hoped the Super Bowl would bring the trailer. Then Oscars night came and went. Now it’s Feb. 26 and there’s still no real trailer for the final season of HBO’s Game of Thrones. Fans of ice and fire aren’t taking this well.Game of Thrones returns for season 8 on April 14, which is why fans are getting antsy. It’s so close. One Twitter use compared the number of trailers we get for Marvel products with those we get for Game of Thrones. There’s a bit of a disparity. The official Game of Thrones account responded with “House Oreo.” Now that sounds like a house worth belonging to.HBO could get away with never releasing a trailer for the final season. Nobody is going to boycott the show because they didn’t get enough advance footage of angry dragons, frozen dead people and sword fights. So pour yourself a Bud Light and twist open an Oreo while you wait. HBO must be sending the trailer out by raven and it got lost somewhere over Westeros. Twitter user Gotmemesworld meme-ified our plight by highlighting the meager teases we’ve gotten so far. It also reminds us of the collective sigh of exacerbation we all spewed when HBO and Bud Light dropped a weird Super Bowl commercial featuring a beer knight and no real season 8 information.

Suspended DIG Mizanur Rahman in the court. Photo: AsaduzzamanSuspended deputy inspector general (DIG) of police Mizanur Rahman was shown arrested in a case over bribing an official of the Anti-Corruption Commission (ACC), reports UNB.Dhaka senior special judge AKM Emrul Kayesh passed the order after accepting a petition filed by the ACC.On 16 July, ACC director Sheikh Mohammad Fanafillah submitted a petition for showing DIG Mizan arrested in the case.Lawyer Ehsanul Haque Samaji stood for DIG Mizan while Mosharraf Hossain Kajal and Tapash Kumar Pal represented the ACC and the state respectively.ACC director Sheikh Mohammad Fanafillah filed a case against suspended DIG Mizanur Rahman and ACC director Khandaker Enamul Basir with Dhaka-1 coordinated district office under the Anti-Corruption Commission, over Tk 4 million bribery scandal on 16 July.A private TV channel reported recently that Mizan gave Tk 4 million to Anti-Corruption Commission (ACC) director Khandaker Enamul Basir to get clean chit in a corruption case.DIG Mizan was an additional commissioner of Dhaka Metropolitan Police (DMP). He was withdrawn on 9 January last year following the allegation of threatening a female news presenter of a private television channel.He had also reportedly married a woman forcibly and tortured her. Mizan allegedly picked the 25-year-old woman up in July, 2017 and then forcibly married her.He had also implicated her in a false case whereby she was arrested and remained in jail for three weeks.The ACC on 24 June filed a case against four people, including DIG Mizanur Rahman, for amassing illegal wealth and concealing information.According to the case statement, the ACC found that DIG Mizan accumulated wealth worth Tk 32.8 million while he concealed information of wealth worth Tk 3.7 million in his wealth statement.
(Phys.org)—A team of researchers with the National Center for Nanoscience and Technology and Beihang University, both in China, has developed a biodegradable triboelectric nanogenerator for use as a life-time designed implantable power source in an animal body. In their paper published in the journal Science Advances the team describes their nanogenerator, its possible uses and the ways it can be tweaked for use in different applications.

Scientists have been working on developing internal devices for many years and several have been created and are now in use inside human patients—the pacemaker is the most well known. But to date, all such devices suffer from the same deficit—none run using an internal power source, which means they must rely on batteries. While batteries are convenient, they tend to run out of power, which means a patient must undergo a surgical procedure to have them replaced and surgical procedures by their very nature are risky because they open the body to possible infection. A better way, as the researchers with this new effort point out, would be to have implantable devices running off a power source that is generated inside the body, such as capturing heat or making use of the movement of blood. The new device they have created generates electricity via triboelectricity—where electricity is generated when two materials touch each other and then separate, one of the common ways that static electricity comes about.The new device consists of two strips of multi-layered material. One of the strips has a flat film outer layer, the other strip has nanometer sized protruding rods on its exterior—when the two strips meet and then pull away, a tiny amount of electricity is created. The layers are kept apart by blocks of a biodegradable polymer; electricity is generated as parts of the body moves in a way that causes the two strips to come into contact and then to pull apart—over and over.Testing of the device showed it was capable of producing a power density of 32.6 milliwatts per square meter, which they found was enough to power a neuron-stimulation device used to steer the way neurons grow. The team claims their device has paved the way for a new generation of internal devices, noting that not only is it biodegradable, but it can be tuned to self-destruct over days, months or even years. Similar devices, they note, could be made to work by utilizing the power from a person breathing or from their heart beating. Photographs from BD-TENG at various stages of the degradation time line suggest that devices encapsulated in PLGA were initially resistant to mass degradation. However, after 40 days, significant mass loss and structure disintegration was initiated. Near-total mass loss was observed at 90 days. Credit: Science Advances (2016).

Zheng et al. Biodegradable triboelectric nanogenerator as a life-time designed implantable power source, Science Advances (2016). DOI: 10.1126/sciadv.1501478AbstractTransient electronics built with degradable organic and inorganic materials is an emerging area and has shown great potential for in vivo sensors and therapeutic devices. However, most of these devices require external power sources to function, which may limit their applications for in vivo cases. We report a biodegradable triboelectric nanogenerator (BD-TENG) for in vivo biomechanical energy harvesting, which can be degraded and resorbed in an animal body after completing its work cycle without any adverse long-term effects. Tunable electrical output capabilities and degradation features were achieved by fabricated BD-TENG using different materials. When applying BD-TENG to power two complementary micrograting electrodes, a DC-pulsed electrical field was generated, and the nerve cell growth was successfully orientated, showing its feasibility for neuron-repairing process. Our work demonstrates the potential of BD-TENG as a power source for transient medical devices. © 2016 Phys.org Team builds implantable piezoelectric nanoribbon devices strong enough to power pacemaker (w/ Video)
