BACKGROUND:

Several studies have investigated the association of breastfeeding status with offspring mortality in Africa, but most studies were from one center only or had limited statistical power to draw robust conclusions.

African swine fever (ASF) is a highly contagious hemorrhagic viral disease of domestic and wild pigs that is responsible for serious economic and production losses. It is caused by the African swine fever virus (ASFV), a large and complex icosahedral DNA virus of the Asfarviridae family. Currently, there is no effective treatment or approved vaccine against the ASFV. pS273R, a specific SUMO-1 cysteine protease, catalyzes the maturation of the pp220 and pp62 polyprotein precursors into core-shell proteins. Here, we present the crystal structure of the ASFV pS273R protease at a resolution of 2.3 Å. The overall structure of the pS273R protease is represented by two domains named the "core domain" and the N-terminal "arm domain." The "arm domain" contains the residues from M1 to N83, and the "core domain" contains the residues from N84 to A273. A structure analysis reveals that the "core domain" shares a high degree of structural similarity with chlamydial deubiquitinating enzyme, sentrin-specific protease, and adenovirus protease, while the "arm domain" is unique to ASFV. Further, experiments indicated that the "arm domain" plays an important role in maintaining the enzyme activity of ASFV pS273R. Moreover, based on the structural information of pS273R, we designed and synthesized several peptidomimetic aldehyde compounds at a submolar 50% inhibitory concentration, which paves the way for the design of inhibitors to target this severe pathogen.

IMPORTANCE African swine fever virus, a large and complex icosahedral DNA virus, causes a deadly infection in domestic pigs. In addition to Africa and Europe, countries in Asia, including China, Vietnam, and Mongolia, were negatively affected by the hazards posed by ASFV outbreaks in 2018 and 2019, at which time more than 30 million pigs were culled. Until now, there has been no vaccine for protection against ASFV infection or effective treatments to cure ASF. Here, we solved the high-resolution crystal structure of the ASFV pS273R protease. The pS273R protease has a two-domain structure that distinguishes it from other members of the SUMO protease family, while the unique "arm domain" has been proven to be essential for its hydrolytic activity. Moreover, the peptidomimetic aldehyde compounds designed to target the substrate binding pocket exert prominent inhibitory effects and can thus be used in a potential lead for anti-ASFV drug development.

The development of pastoralism transformed human diets and societies in grasslands worldwide. The long-term success of cattle herding in Africa has been sustained by dynamic food systems, consumption of a broad range of primary and secondary livestock products, and the evolution of lactase persistence (LP), which allows digestion of lactose...

Mole-rats are champions of self-preservation, with increased longevity compared to other rodents their size, strong antioxidant capabilities, and specialized defenses against endogenous oxidative stress. However, how the brains of these subterranean mammals handle acute in vivo hypoxia is poorly understood. This study is the first to examine the molecular response to low oxygen in six different species of hypoxia-tolerant mole-rats from sub-Saharan Africa. Protein carbonylation, a known marker of DNA damage (hydroxy-2’-deoxyguanosine), and antioxidant capacity did not change following hypoxia but HIF-1 protein levels increased significantly in the brains of two species. Nearly 30 miRNAs known to play roles in hypoxia-tolerance were differentially regulated in a species-specific manner. The miRNAs exhibiting the strongest response to low oxygen stress inhibit apoptosis and regulate neuroinflammation, likely providing neuroprotection. A principal component analysis using a subset of the molecular targets assessed herein revealed differences between control and hypoxic groups for two solitary species (Georychus capensis and Bathyergus suillus), which are ecologically adapted to a normoxic environment, suggesting a heightened sensitivity to hypoxia relative to species that may experience hypoxia more regularly in nature. By contrast, all molecular data were included in the PCA to detect a difference between control and hypoxic populations of eusocial Heterocephalus glaber, indicating they may require many lower-fold changes in signaling pathways to adapt to low oxygen settings. Finally, none of the Cryptomys hottentotus subspecies showed a statistical difference between control and hypoxic groups, presumably due to hypoxia-tolerance derived from environmental pressures associated with a subterranean and social lifestyle.

Etravirine (ETR) is a nonnucleoside reverse transcriptase inhibitor (NNRTI) used in treatment-experienced individuals. Genotypic resistance test-interpretation systems can predict ETR resistance; however, genotype-based algorithms are derived primarily from HIV-1 subtype B and may not accurately predict resistance in non-B subtypes. The frequency of ETR resistance among recombinant subtype C HIV-1 and the accuracy of genotypic interpretation systems were investigated. HIV-1_LAI containing full-length RT from HIV-1 subtype C-positive individuals experiencing virologic failure (>10,000 copies/ml and >1 NNRTI resistance-associated mutation) were phenotyped for ETR susceptibility. Fold change (FC) was calculated against a composite 50% effective concentration (EC₅₀) from treatment-naive individuals and three classifications were assigned: (i) <2.9-FC, susceptible; (ii) ≥2.9- to 10-FC, partially resistant; and (iii) >10-FC, fully resistant. The Stanford HIVdb-v8.4 was used for genotype predictions merging the susceptible/potential low-level and low-level/intermediate groups for 3 x 3 comparison. Fifty-four of a hundred samples had reduced ETR susceptibility (≥2.9-FC). The FC correlated with HIVdb-v8.4 (Spearman’s rho = 0.62; P < 0.0001); however, 44% of samples were partially (1 resistance classification difference) and 4% completely discordant (2 resistance classification differences). Of the 34 samples with an FC of >10, 26 were HIVdb-v8.4 classified as low-intermediate resistant. Mutations L100I, Y181C, or M230L were present in 27/34 (79%) of samples with an FC of >10 but only in 2/46 (4%) of samples with an FC of <2.9. No other mutations were associated with ETR resistance. Viruses containing the mutation K65R were associated with reduced ETR susceptibility, but 65R reversions did not increase ETR susceptibility. Therefore, genotypic interpretation systems were found to misclassify ETR susceptibility in HIV-1 subtype C samples. Modifications to genotypic algorithms are needed to improve the prediction of ETR resistance for the HIV-1 subtype C.

JOHANNESBURG -- The dealer had a stash, but the young woman wasn't getting through the door without an introduction. That's where her friend, already a trusted customer, came in. And even then there were complications.The woman wanted Stuyvesants. The dealer had Courtleighs. But in a South Africa where the sale of cigarettes is newly illegal, quibblers risk nicotine fits.She took the Courtleighs and high-tailed it out of there."I feel like I'm buying cocaine," said the woman, 29, who asked not to be named for fear of being fined or arrested.In late March, in the midst of the coronavirus outbreak, the South African government banned the sale of tobacco and alcohol as part of a broad lockdown -- one of the strictest anywhere. But even as the government has begun rolling back the lockdown, the bans remain in effect.A government minister, Nkosazana Dlamini-Zuma, cited "COVID-19 reasons" for maintaining the ban.Dlamini-Zuma, a doctor who served as health minister in the 1990s and is now cooperative governance minister, said that "besides the effects itself on the person's lungs," there were concerns that smoking could promote coronavirus infection."The way sometimes tobacco is shared does not allow for social distancing," she said, "but actually encourages the spread of the virus."Defending the ban of alcohol sales amid cries of protest from the liquor industry, President Cyril Ramaphosa said alcohol was "a hindrance to the fight against coronavirus.""There are proven links between the sale and consumption of alcohol and violent crime, motor vehicle accidents and other medical emergencies at a time when all public and private resources should be preparing to receive and treat vast numbers of COVID-19 patients," the president said in a statement.The government has also cited the risk of domestic violence in households where families are isolated at home.Perhaps not surprisingly, an underground market in both cigarettes and alcohol quickly sprung up.Like bootleg markets everywhere, it relies on word-of-mouth, as the 29-year-old woman who settled for the Courtleighs soon learned.She made her purchase in a suburb of Vereeniging, a city south of Johannesburg, where dealers are said to sell only to buyers referred by someone they know. And they sell only from their homes to avoid driving around with large quantities of cigarettes, since if they were to be caught at one of the dozens of police roadblocks set up around the country, they could be arrested on the spot.Instead, the smoker carries the risk -- and the cost. A pack of 20 cigarettes now goes for upward of 150 rand (about $8), three times the old legal price. Underground alcohol prices have also skyrocketed. A bottle of low-end vodka that usually sells for 120 rand ($6) now sells for at least 400 rand ($21).South Africa lifted its nationwide lockdown on May 1 but is continuing to implement strict social distancing and face mask rules. Already under siege from HIV, the country has around 8,200 confirmed cases of the coronavirus and has reported about 160 deaths.The country had implemented one of the world's most stringent lockdowns after recording its first coronavirus-related death in March. In addition to banning the sale of cigarettes and alcohol, the regulations banned jogging and dog-walking, and shuttered parks.Before the lockdown, with a ban looming, some smokers stocked up on cartons of cigarettes. But when the ban on cigarettes was extended beyond May 1, things for smokers began to grow tense.Now it's a matter of who you know. The cafe owner willing to slip a box under a container of milk, perhaps, or a supermarket cashier willing to steal and resell cigarettes languishing in the storeroom.In one Pretoria township where everyone knows everyone -- including the police -- few dare sell cigarettes from their homes. Instead, dealers hide among young men milling around on the neighborhood corner.A 23-year-old smoker said that when he saw a group of four men sharing a cigarette, he approached them to find out where they had found the contraband. They just so happened to be selling, they told him.Desperate after a failed attempt to quit smoking, he said, he paid 160 rand for his favorite brand and "ran home," where he took a photograph of the sealed pack, planning to share it on WhatsApp with envious fellow smokers.But when he opened the pack, a cloud of sawdust choked him. There was not a cigarette to be found.Smokers say they are finding fake cigarettes in sealed boxes that look exactly like legitimate brands. And those who are desperate enough are buying unknown brands that have appeared during the lockdown, with names like Pineapple and Chestel, and are notorious for inducing immediate coughing.The tobacco industry has not taken kindly to the government's new policy.The ban has fueled an underground cigarette trade that was thriving even before the lockdown. By some estimates, it made up more than 30% of the market, depriving the above-ground tobacco industry of profit and the government of tax revenue.Now both industry and government are losing even more.The country's largest cigarette manufacturer, British American Tobacco South Africa, at one point threatened legal action if the government did not drop its ban, but Wednesday changed course. "We have taken the decision not to pursue legal action at this stage," it said in a statement, "but, instead, to pursue further discussions with government."The company said, "We are convinced that by working together we can find a better solution that works for all South Africans and removes the threat of criminal sanction from 11 million tobacco consumers in the country."The ban on cigarettes and alcohol has set off a debate on civil liberties in a country with one of the world's most liberal constitutions. While South Africa was an early adopter of public smoking regulations, many see the bans as a symbol of government overreach.Though its coronavirus policies may have succeeded in keeping the outbreak in check, some are calling the government hypocritical. Junk food remains readily available. And officials strictly limited outdoor exercise during the lockdown.In a country increasingly struggling with diabetes and obesity, such inconsistencies undercut the government's argument that it is guarding the public's health, said one South African constitutional law expert, Pierre De Vos."In the long term, if the government overreaches and it wants to continue imposing these limits when the threat has subsided, I think the courts will invalidate this," he said.Still, the ban may have yielded at least one former smoker: the man who bought the box of sawdust."I cannot just go around losing money like that," he said. "I just said to myself, 'Nah, man, it's not worth it. I'll stay home and eat sweets, as that's what's legal now.'"This article originally appeared in The New York Times.(C) 2020 The New York Times Company

We called Greg Carr the other day to talk about the spread of the coronavirus in Africa. Carr, who has been featured in Nautilus, is the founder of the Gorongosa Restoration Project, a partnership with the Mozambique government to revive Gorongosa National Park, that environmental treasure trove at the southern end of the Rift Valley. The 1,500 square-mile park, about the size of Rhode Island, was first given animal refuge status in the 1920s by the Portuguese, and for years was a favorite of European tourists. But in 1983 civil war broke out and the park became a no-man’s land. The place was poached to death, closed up and didn’t reopen until 1992.

Renewal began in 2004 and in 2008 the government signed a restoration agreement with Carr’s foundation. The agreement, which lasts through 2043, envisions a “human rights park” that will restore both ecosystems and economic vitality. After 11 years of rebuilding infrastructure, reintroducing animals, including hippos and wildebeests, and working with local communities, Gorongosa is thriving again. The park now serves as a model for future conservation. Today some 200,000 people live around the park in a “sustainable development zone” that includes education, employment opportunities, and health service. About 700 people have full time jobs in the park; another 300, part time. Naturalist E.O. Wilson calls Gorongosa “a window on eternity.”

“If there’s one thing the rest of the world can learn from Africans, it would be their resilience.”

Carr is a 60-year-old entrepreneur and philanthropist who grew up in Idaho and in his mid twenties co-founded Boston Technology, a voice mail company. By the time he turned 40 he had amassed his fortune and couldn’t see the fun in doing it all over again, and so turned to philanthropy. These days he’s in Idaho Falls, on the phone six hours a day, getting the latest reports from his staff in the park, now closed until further notice.

The coronavirus news from Mozambique is mixed, as it is in much of sub-Saharan Africa. With the exception of South Africa, with over 7,500 confirmed cases of COVID-19 and 148 deaths, some countries below the Equator have fewer than 100 cases. As of May 6, there were just 81 cases in Mozambique and no deaths. If these numbers don’t blow up, the quick explanation might hold that the median age in Sub Saharan Africa is under 20, just 17.6 in Mozambique; population density is low (103 people per square mile); and there’s relatively limited direct contact with heavily infected countries in other parts of the world. 

Still, many experts fear chaos is inevitable. Underlying conditions in Mozambique include implacable poverty and a 60-year history of colonial and civil wars. On another front, in early April, in northern Mozambique, an Isis group shot or beheaded 52 young people because they refused to be recruited. Add a 48 percent literacy rate for women, 60 percent for men. The country also suffers the world’s eighth-highest incidence of HIV; 1.5 million people have contracted the virus and nearly 40,000 people have died. Finally, a large number of Mozambicans go to South Africa for work and then return. Testing is rare in the entire country.

In March, CDC Africa sent out a national directive requiring social distancing. “People are going to pay more attention to that in the cities than they are in rural Mozambique, at least until the virus really comes,” Carr said the other day. “Now, if you live in rural Mozambique, you don’t have the luxury of saying, ‘I’m isolating at home.’ People have to go out every day, to get food and water, from 40 to 60 liters a day, they have to tend to their farms. The idea of social distancing is a bit impossible for these folks.” He added, “Schools are closed and we are making our own masks for people. We all know there’s no treatment per se or certainly vaccine. If this hits, we’ll only be able to offer people Tylenol and soup.”

Cases in Mozambique could shoot up as mine workers continue to return home from their jobs in South Africa. “In my opinion,” said Carr, “Mozambique does not have the capacity to deal with this type of pandemic, as there are few qualified health personnel and the high level of poverty leads people to resist isolating themselves, as they look for alternatives to take care of their families. Our Gorongosa teams are in the field, spreading prevention messages, distributing masks and water purification.” 

Berta Barros, head nurse at Gorongosa, told Carr recently she has three main worries: lack of COVID-19 test kits, lack of healthcare professionals to respond to sick patients, and shortage of medications for treatment. “Mozambique has a population close to 30 million and we only have 34 ventilators,” Barros said. “It’s beyond impossible to work and choose who to save.”

Carr often talks about Mozambique as though he was Mozambican. “We’re very practical people,” he’ll say. “We’re not really theoretical. We’re just going to work our way through this.” He shies away from broad, open-ended questions about Africa, much less cultural comparisons and grand conclusions. “Africa is more than 1 billion people in 54 countries with, what, 2,500 languages? To make a statement like, ‘Africa is this…’ Frankly, I just think a lot of it is complete baloney.”

At the same time, says Carr, “If there’s one thing the rest of the world can learn from Africans, it would be their resilience. We’ve had five years of war in Mozambique and then last year we had a cyclone that killed nearly 1,000 people. I didn’t even mention the two droughts we had in the last seven years and the armyworm that came through and ate everybody’s maize. These people had their homes washed away in a flood last year, lost everything. So they rebuild their homes and then someone says, ‘Hey, there might be a virus coming through.’ It’s just one thing after another.”

What impact might the pandemic have on animals in the park? What effect will it have on just recovered antelope populations, for example, and the inevitable increase in poaching as tourism subsides? How many resources will need to be taken away from the war on other diseases to fight this? Impossible to say. But an anecdote came to Carr’s mind that suggests the vagaries of death in Southern Africa. “I got a call from a dear friend of mine yesterday, a Mozambique good friend, who said her aunt had just died. I said, ‘Wow, do you think it was COVID?’ She goes, ‘No, she’d been suffering for a while with a bad kidney.’ Life is tough in Africa. Do we know for sure this woman didn’t also have COVID and that contributed? Maybe. The truth about Africa is that disaster is hardly news. Malaria is the most prolific killer. And when they turn 50, people die and often no one knows exactly what the cause was. It’s just the way life is.”
