Paragraph: Prime Minister Shinzo Abe declared a state of emergency in Tokyo and six other prefectures last week in response to the coronavirus outbreak. While many businesses in Tokyo and elsewhere are now shut, most convenience stores have stayed open as they are considered essential. There are around 58,000 convenience stores throughout Japan. Most are open 24 hours and sell everything from pre-made bento lunches to beer and neckties. They also offer package delivery and bill payment services. “I actually feel safer,” said 53-year-old restaurant owner Isao Otsuka, who was shopping at one of the roughly 150 7-Eleven stores, mainly in Tokyo, that have installed the transparent plastic curtains. 7-Eleven’s owner, Seven & i Holdings, has asked convenience store workers to wear masks, check their temperatures, wash their hands frequently and sterilise surfaces. The new coronavirus spreads from person to person through small droplets from the nose or mouth via coughing or sneezing, according to the World Health Organization. Scientists have also said the virus can remain infectious in droplets in the air for hours and on surfaces for days. Japan had recorded 7,411 cases of infection and 138 deaths from the virus as of Monday, public broadcaster NHK said, with more than 2,000 cases in Tokyo, a sharp rise from late March. Claim: With plastic sheets, Japan's convenience stores target social distancing.
Some of Japan’s ubiquitous convenience stores have taken a novel approach to social distancing by hanging plastic sheets from the ceiling to provide a barrier between customers and staff at the cash register during the coronavirus pandemic.

Paragraph: Authorities have urged South Koreans to stay home and maintain social distancing, as imported cases and new outbreaks around small clusters continued to emerge while an overall tally in new infections has been declining. Restrictions on high-risk events such as religious, sports and entertainment gatherings took effect on Sunday, requiring facilities to ensure space between the attendees and allowing local governments to conduct on-site checks and issue fines. “Our fight against the virus is a three-legged race,” President Moon Jae-in said on Sunday, referring to the need for the community to work in step with the government. “It doesn’t matter even if you are not sick and doing well by yourself.”  Most churches have turned to online services over the past few weeks, but local media said there were several that pushed ahead with physical gatherings on Sunday, prompting scuffles with police and protests by residents calling for disbanding. At the Sarang Jeil Church in Seoul, several attendees tried to force out a dozen police officers, domestic newswire Yonhap reported. A video uploaded by a purported member of the church on YouTube showed a woman lying on the ground while another was heard shouting “Why are you doing this? Is this North Korea?”  Yonhap quoted a city official as saying the church did not follow rules and ensure sufficient space among the attendees. Reuters was not immediately able to reach the police or the Seoul city government for comment and calls to the church for comment were unanswered. Elsewhere, Yonhap news photos showed a group of residents staging a rally in front of the Yonsei Central Baptist Church in Seoul, holding up a sign calling for a halt to services for the safety of neighbors. More than half of South Korea’s cases were traced to a fringe Christian church in the hard-hit southeastern city of Daegu. This week, some 60 members of a Protestant church in Seongnam, south of Seoul, have also tested positive this week. The Korea Centers for Disease Control and Prevention (KCDC) reported 98 new coronavirus cases, bringing national infections to 8,897. The death toll rose by six to 110. The daily tally marked the 11th day in a row the country has posted new infections of around 100, compared with the peak of 909 cases recorded on Feb. 29. The KCDC renewed caution for overseas travelers on Sunday, after the government toughened border checks and imposed a two-week mandatory quarantine for all long-term arrivals from Europe due to a spike in returnee cases. At least 15 travelers tested positive on Saturday, the KCDC said, eight of them from Europe and three from the United States. Most of them were South Koreans. “We’re implementing intensive social distancing over the next 15 days,” KCDC deputy director Kwon Jun-wook said at a briefing. “After that, we will open schools and return to a regular life cycle in the face of the battle on the coronavirus.” Claim: South Korean churchgoers scuffle with police as virus curbs on gatherings kick in.
Members of a South Korean church scuffled with police on Sunday, media reported, as government restrictions on religious services and other gatherings due to the spread of the coronavirus took effect.

Paragraph: The drug fully eradicated medulloblastoma tumors in mice in 2004. But further testing showed it caused permanent bone damage in immature mice, Tom Curran of The Children’s Hospital of Philadelphia and colleagues found. Writing in the journal Cancer Cell, they said the drug, known by its experimental name HhAntag, will need to be developed with caution. And, they said, similar drugs will need careful testing. HhAntag, made by California-based Genentech, affects a gene called Hedgehog, involved in both normal development and in cancer. It is a so-called signal transduction inhibitor, designed to interrupt Hedgehog’s cancer-causing effects. Several such drugs are currently in pediatric clinical trials. “While it is not clear that the bone defects we observed in mice would also occur in children, and while signal transduction inhibitors may still represent a highly promising approach to treating pediatric cancer, it may be important to perform preclinical testing in young animals before moving ahead to clinical trials,” Curran said in a statement. Medulloblastomas account for about one in five childhood brain tumors. “Current therapy, involving a combination of surgery, radiation, and chemotherapy, is relatively successful with a five year survival rate of 78 percent,” Curran’s team wrote. “However, the prognosis is much worse for patients younger than 3 and in older patients with metastatic disease.”    The Hedgehog-inhibiting drugs had been considered a promising new approach for these young patients. But even brief use of the drug in 10- to 14-day-old mice caused permanent damage, Curran found. “We already knew that the same biological pathway involved in the growth of tumors was also involved in bone development but we did not expect temporary inhibition to cause an irreversible change in bone growth,” Curran said. It may be possible to find a way to protect the growing bones of children and still use the drug, Curran said. “Thus, although the impact of a brief suppression of Hedgehog pathway on bone development in mice is quite striking, this should not preclude attempts to develop a highly promising anti-cancer treatment for pediatric medulloblastoma,” his team concluded. Claim: Promising Cancer Drug May Endanger Child's Bones.

A compound that looked promising for treating a brain tumor found mostly in children may damage growing bone — possibly making it too dangerous to use in young patients, researchers reported on Monday.
