A |     Kyiv, Oct 12 (UNI) Ukrainian President Volodymyr Zelensky has urged countries to hit Russia with more sanctions in response to "a new wave of terror" after Monday's attacks on Ukraine.

At least 19 people were killed and scores more injured when Russian missiles hit regions across the country. At that point defiant, he said the attacks will only "delay our recovery a little".

Following more strikes on Tuesday, Zelensky called on the West to find new ways to apply political pressure to Russia and support Ukraine, the BBC reported.

Zelensky said: "For such a new wave of terror there must be a new wave of responsibility for Russia - new sanctions, new forms of political pressure and new forms of support for Ukraine."

"The terrorist state must be deprived of even the thought that any wave of terror can bring it anything."

The calls came after he met the G7 group of nations for emergency virtual talks on Tuesday.

The bloc - which consists of Canada, France, Germany, Italy, Japan, the UK and US - promised to continue providing "financial, humanitarian, military, diplomatic and legal" support to his country "for as long as it takes".

Russian President Vladimir Putin said the attacks were retaliation for Saturday's explosion on a key bridge linking Russia to Crimea.

Western countries have already placed widespread sanctions against Russian businesses as well as allies of Putin since the invasion of Ukraine on February 24.

This includes removing major Russian banks from the international financial messaging system Swift, and sanctioning more than 1,000 Russian individuals and businesses - including oligarchs.

While the US has banned all Russian oil and gas imports, the EU has been reluctant to do so because it relies on Russia for about 40% of its gas needs.

Monday's sudden barrage of missile strikes was the heaviest bombardment Ukraine has seen since the early days of the war. Several strikes hit Kyiv city centre in a first. The capital city has not been targeted in months, the BBC added.

On Tuesday, Zelensky said 28 more missiles were fired, 20 of which were shot down. These included Iranian combat drones, he claimed which the BBC said has not been verified.

"If it wasn't for today's strikes, we would have already restored the energy supply, water supply and communications that the terrorists damaged yesterday," the president said in his nightly address on Tuesday evening.

"Today, Russia will achieve only one additional thing: it will delay our recovery a little."

He added that restoration works were taking place "quickly and efficiently" throughout the country, and that electricity and communication had been restored to most cities and villages targeted in Monday's attacks.

"Where there was destruction, the infrastructure will be renewed everywhere. Where there were losses, there is already or will be construction," he said.

On Tuesday, reports also emerged of a mass grave being found in recently liberated Lyman, in the eastern Donetsk region.

UNI ING。全球蝙蝠传播的病毒对人类和动物健康构成威胁。

B | 丝状病毒,尤其是埃博拉病毒和马尔堡病毒,因其致病性而臭名昭著。它们能通过影响许多器官和破坏血管,在人类中引起严重的,通常是致命的发烧。这是在印度塔米尔纳杜马德拉伊的一座寺庙里看到的罗塞图斯·莱切诺提伊。资料来源:印度蝙蝠保护协会杜克新加坡国立大学医学院研究员、中国科学家Rajesh Puttaswamaiah在中国的果蝠(罗塞特蝙蝠)中发现了一种新的丝状病毒。”研究蝙蝠传播丝虫病的遗传多样性和地理分布对风险评估和疾病暴发的预防非常重要,因为它们可以在没有预警的情况下影响公众,并产生毁灭性的后果,”医学院新传染病研究项目主任王林发教授说。杜克新加坡国立大学,本研究的主要作者。

C | 研究人员在分析果蝠丝状病毒的多样性时发现了这种新病毒。他们把它命名为孟拉病毒,因为它是在中国云南省孟拉县发现的。他们从蝙蝠样本中检测出病毒,并研究了其序列和功能特征。结果表明,蒙拉病毒属于丝状病毒。孟加拉病毒在遗传学上是独一无二的。它与其他已知的丝状病毒共享32-54%的基因序列。

D | 与其他丝状病毒相比,它在不同的地理位置被发现。这个新的属,可能包括多个物种,位于进化树中埃博拉病毒和马尔堡病毒之间。研究人员检测了来自不同动物细胞的孟加拉病毒,发现与其他丝状病毒一样,孟加拉病毒具有种间传播的潜在风险。结果表明,孟加拉病毒在进化过程中与埃博拉病毒和马尔堡病毒有着密切的联系,并具有重要的功能相似性。

E | 例如,孟加拉病毒的基因组与其他丝状病毒相同,编码7个基因。孟加拉病毒也使用与埃博拉病毒和马尔堡病毒(一种叫做NPC1的蛋白质)相同的分子受体进入细胞并引起感染。杜克新加坡国立大学医学院高级副院长帕特里克·凯西教授说:“随着全球化的发展,识别和评估传染病爆发的潜在风险,并从中制定有效的控制策略和治疗措施非常重要。”在中国的果蝠。将进行进一步的试验,以评估病毒向其他物种传播的风险。
