探访曲江新区恢复餐饮堂食首日:餐厅提示隔桌用餐 鲜有顾客店内就餐******

  

\

  3月21日,西安曲江新区恢复餐饮堂食,要求严控同一时间段就餐人数,原则上不得超过座位数的50%。记者走访曲江新区部分餐饮门店看到,门店基本通过隔桌就餐的方式对顾客进行限流,不过由于是恢复堂食的首日,在店内就餐的顾客并不多。

  在金地广场曲江店3层的绿茶餐厅,记者看到餐厅公共区域内,一些桌子摆放着餐具,而其相邻的桌面上则放置着“隔桌用餐,感谢配合”的提示牌,并撤掉了配套的座椅。

  餐厅负责人岳女士说,尽管已经恢复了堂食,但第一天上门用餐的顾客并不多,“中午总共就来了五六桌吧,这段时间主要靠线上,外卖每天差不多有100多单。上周完全禁止堂食之前,也有一段时间限流50%,实际上大家都很自觉,不用我们限制,每天同一时间的顾客都远远到不了50%。”

  记者了解到,为防范化解食品安全风险,守牢食品安全底线,曲江新区恢复餐饮堂食第一天,西安市市场监管局曲江分局便以此为契机,对辖区餐饮单位食品安全“守底线,查隐患,保安全”专项行动开展督导检查。

  “餐饮堂食因疫情暂停了一周,一些餐厅食材可能出现库存积压。此次我们主要对餐饮单位食材保质期、后厨环境卫生、工作人员健康证等方面进行检查。”西安市市场监管局曲江分局南湖市场监督管理所所长赵继峰介绍,他们将认真落实好属地监管责任,及时消除食品安全隐患,用心护航“舌尖上的安全”。

'Historic': US surgeons successfully implant pig heart in human******

AFP。

This handout photo released by the University of Maryland School of Medicine on Monday shows surgeons performing a transplant of a heart from a genetically modified pig to patient David Bennett, in Baltimore, Maryland, last Friday.。

Surgeons in the United States have successfully implanted a heart from a genetically modified pig in a 57-year-old man, a medical first that could one day help solve the chronic shortage of organ donations.。

The "historic" procedure took place last Friday, the University of Maryland Medical School said in a statement on Monday. While the patient's prognosis is far from certain, it represents a major milestone for animal to human transplantation.。

The patient, David Bennett, had been deemed ineligible for human transplant – a decision that is often taken when the recipient has very poor underlying health.。

He is now recovering and being carefully monitored to determine how the new organ performs.。

"It was either die or do this transplant. I want to live. I know it's a shot in the dark, but it's my last choice," the Maryland resident said a day before the surgery.。

Bennett, who has spent the last several months bedridden on a heart-lung bypass machine, added: "I look forward to getting out of bed after I recover."

The Food and Drug Administration granted emergency authorization for the surgery on New Year's Eve, as a last-ditch effort for a patient who was unsuitable for conventional transplant. "This was a breakthrough surgery and brings us one step closer to solving the organ shortage crisis," said Bartley Griffith, who surgically transplanted the pig heart.。

"We are proceeding cautiously, but we are also optimistic that this first-in-the-world surgery will provide an important new option for patients in the future."

Muhammad Mohiuddin, who co-founded the university's cardiac xenotransplantation program, added the surgery was the culmination of years of research, involving pig-to-baboon transplants, with survival times that exceeded nine months.。

"The successful procedure provided valuable information to help the medical community improve this potentially life-saving method in future patients," he said.。

Bennett's donor pig belonged to a herd that had undergone genetic editing procedures.。

Three genes that would have led to rejection of pig organs by humans were "knocked out," as was a gene that would have led to excessive growth of pig heart tissue. Six human genes responsible for human acceptance were inserted into the genome, for a total of 10 unique gene edits.。

The editing was performed by Virginia-based biotech firm Revivicor, which also supplied the pig used in a breakthrough kidney transplant on a brain dead patient in New York in October.。

But while that surgery was purely a proof-of-concept experiment, and the kidney was connected outside the patient's body, the new surgery is intended to save a person's life.。

The donated organ was kept in an organ-preservation machine ahead of the surgery, and the team also used an experimental new drug made by Kiniksa Pharmaceuticals along with conventional anti-rejection drugs to suppress the immune system.。

About 110,000 Americans are currently waiting for an organ transplant, and more than 6,000 patients die each year before getting one, according to official figures.。

To meet demand, doctors have long been interested in so-called xenotransplantation, or cross-species organ donation, with experiments tracing back to the 17th century.。

Dortmund hoping for Haaland return to fight against Bayern******

BERLIN, Oct. 31 (Xinhua) -- Borussia Dortmund hope their star striker Erling Haaland would be right back from injury to face Bayern Munich in early December.。

As one of the world's best strikers, Haaland is currently sidelined with a hip flexor injury and is expected to be out at least until December.。

Dortmund's Sports Director Sebastian Kehl said in an interview on Sunday that they will "do everything so that Erling is there for this game."

Kehl emphasized that they know how important the duels between Borussia Dortmund and Bayern Munich will be and what difference Haaland can make, adding "to have him there would be unbelievably important for us."

Although Haaland wants to be back quickly, Kehl believed that it is their responsibility to take care of his career. "We carry a responsibility for his career," said Kehl. Enditem。
