A total of 27 Hong Kong residents who left Morocco on a chartered flight arranged by the Chinese Embassy in the Kingdom of Morocco arrived in Guangzhou today.

Among them, 26 people subsequently took the coaches arranged by the Hong Kong Special Administrative Region Government to return to Hong Kong through the Shenzhen Bay Port and have arrived at AsiaWorld-Expo.

One Hong Kong resident chose to stay in Guangzhou for a 14-day isolation period for medical surveillance in accordance with the relevant requirements.

Banks and financial institutions taking part in providing mortgage loans for the Housing Authority Subsidised Sale Flats Scheme (SSFS) may offer a mortgage principal moratorium plan to the scheme’s mortgagors.

The authority today wrote to these institutions to confirm and agree that such a plan is applicable for SSFS flats.

Principal repayment may be deferred for a maximum 12-month period and the mortgage loan repayment period may be extended correspondingly by a maximum of 12 months.

The principal moratorium period may commence by December 31 this year at the latest.

The arrangement is applicable to the Home Ownership Scheme, the Private Sector Participation Scheme, the Buy or Rent Option Scheme, the Tenants Purchase Scheme and the Green Form Subsidised Home Ownership Scheme in the primary market and under the Secondary Market Scheme.

To encourage participating financial institutions to provide mortgage loans and better mortgage terms for SSFS flat purchasers, the authority provides a mortgage default guarantee for them.

It undertakes to meet the shortfall in repayment in the event of default by the borrowers under specified circumstances during the guarantee period.

Due to the requirements in the guarantee deed on the mortgage loan period and the monthly instalment amount, participating financial institutions may not be able to offer a mortgage principal moratorium plan to SSFS flat owners.

In light of the economic downturn arising from the COVID-19 outbreak, the authority confirmed today that a mortgage principal moratorium plan is applicable for SSFS flats.

The move will encourage participating financial institutions to offer such a plan to SSFS flat owners, reducing their burden of mortgage repayment.

Applications for the $1.3 billion in subsidies earmarked for registered owners of goods vehicles and green minibus operators under the Anti-epidemic Fund opened today, the Transport Department announced.

A one-off non-accountable subsidy of $10,000 will be provided to each registered goods vehicle owner for each goods vehicle.

From today until September 30, registered owners of goods vehicles who have received the department's letters must use the registration PIN provided in the letters for submission of registrations through GovHK.

After successful completion of registration, the subsidy will be disbursed to the designated local bank account provided in the registration through autopay in about two to three weeks.

Cross-boundary goods vehicle drivers who conduct nucleic acid tests in Hong Kong can apply for the subsidy on an accountable basis, with the maximum amount being $350 per test.

A one-off non-accountable subsidy of $30,000 per green minibus will be provided to each holder of a Passenger Service Licence-Public Light Bus (Scheduled) Service who has been approved to operate a relevant green minibus route package.

The department briefed the green minibus trade today on the subsidy arrangement and application details with the distribution of the application forms.

Green minibus operators are required to send the completed application forms to the department by post on or before September 30.

After the department has verified their submissions, the subsidy will be disbursed through autopay in about one month.

To assist the transport trades to cope with operational demands in the prevailing economic environment, the Government has rolled out the fuel subsidy and one-off subsidy measures under the first round of the Anti-epidemic Fund progressively.

As of mid-April, the department has received applications for subsidies from three franchised bus companies, 10 franchised and licensed ferry operators, Hong Kong Tramways Limited, registrations from 1,700 registered owners of non-franchised public buses, school private light buses and hire cars. Over $100 million of the subsidies have been disbursed.

Property management companies and owners’ organisations which have successfully applied for an anti-epidemic support scheme were reminded today to disburse the hardship allowance to frontline workers as soon as practicable upon receiving the subsidies.

The Home Affairs Department said the workers concerned shall acknowledge receipt of the allowance using the prescribed forms.

The property management companies or owners’ organisations shall submit a report on the allowance’s overall payment to the Property Management Services Authority within three months of receiving the subsidies.

The department and/or the authority will conduct a random review and check to ensure that the frontline property management workers have received the allowance.

As of today, more than 8,160 applications have been received for the Anti-epidemic Support Scheme for Property Management Sector under the Anti-epidemic Fund.

About 2,850 applications have been approved, involving more than $100 million in subsidies and benefitting more than 17,500 building blocks and about 25,500 frontline workers.

Call 3696 1156 or 3696 1166 for enquiries.

The Commerce & Economic Development Bureau today announced that the subsidy quota for three mask production lines have been reassigned.

Three production lines, previously approved under the Local Mask Production Subsidy Scheme, have withdrawn from the scheme, the Government said.

The subsidy quota concerned has been allocated to SDL Skin (Asia), Safeguard HK and SwissTech.

SDL Skin (Asia) has been approved for obtaining a subsidy for a second production line and is expected to supply an average of 1.6 million masks every month to the Government. The production line may receive a subsidy of up to $1 million.

Safeguard HK has been approved for obtaining a subsidy for one production line and is expected to supply an average of 500,000 masks to the Government every month. The production line may receive up to $2 million.

SwissTech has been approved for obtaining a subsidy for one production line and is expected to supply an average of 2 million masks every month to the Government and produce a further 1 million masks on average monthly for the local market.

The production line may receive up to $3 million.

It is estimated that when all 20 subsidised lines under the scheme are in full production, they will collectively supply 33.85 million masks to the Government and a further 7.15 million to the local market monthly.

The companies which withdrew from the scheme were CareHK and Shang Manufactory.

The Government did not sign agreements with or make disbursements to these firms.

The Food & Environmental Hygiene Department announced that applications for the Catering Business (Social Distancing) Subsidy Scheme, under the second round of the Anti-epidemic Fund, will start from May 5.

The department said the scheme, which is estimated to benefit 16,000 catering outlets and their employees, will provide financial relief measures to the catering businesses which have been hard hit by the COVID-19 epidemic and social distancing measures.

It will provide subsidies ranging from $250,000 to $2,200,000 to eligible licence holders of general restaurants, light refreshment restaurants, marine restaurants and factory canteens in operation according to the floor area of the premises as specified on the licence.

The primary goal of the scheme is to support the payment of employees' salaries during a six-month period following application approval.

To provide immediate relief to the catering sector, the subsidy will be dished out upfront, in two tranches.

To avoid abuse, applicants should undertake that there will be no redundancy of staff for three months on receipt of the first tranche of subsidy and another three months on receipt of the second tranche.

They should also undertake that not less than 80% of the subsidies for respective months would be used to pay salaries of staff working at the premises.

Applicants should submit within a specified period a certificate issued by a Certified Public Accountant (practising) on its total staff salaries and total number of salaried staff for each of the months covered by the subsidy.

They should also submit a certificate issued by a CPA on its total staff salaries and total number of staff working at the premises for the month of March this year.

To avoid double benefits, applicants should declare that they have not and will not submit any application under the Employment Support Scheme.

Each catering outlet directed to close its licensed premises under the Prevention & Control of Disease (Requirements & Directions) (Business & Premises) Regulation, including karaoke establishments, nightclubs and bars or pubs, is eligible for a further one-off subsidy of $50,000.

Applications should be submitted to the department's District Environmental Hygiene Offices in person or by mail. Food licence holders can also submit their applications through the website.

The deadline for application is June 5.

Upon receipt of the completed application form and supporting documents and after verification, the disbursement of the first tranche of subsidies can generally be made in two to three weeks by crossed cheques to the corresponding licensed food premises.

β-Glucocerebrosidase (GBA) hydrolyzes glucosylceramide (GlcCer) to generate ceramide. Previously, we demonstrated that lysosomal GBA1 and nonlysosomal GBA2 possess not only GlcCer hydrolase activity, but also transglucosylation activity to transfer the glucose residue from GlcCer to cholesterol to form β-cholesterylglucoside (β-GlcChol) in vitro. β-GlcChol is a member of sterylglycosides present in diverse species. How GBA1 and GBA2 mediate β-GlcChol metabolism in the brain is unknown. Here, we purified and characterized sterylglycosides from rodent and fish brains. Although glucose is thought to be the sole carbohydrate component of sterylglycosides in vertebrates, structural analysis of rat brain sterylglycosides revealed the presence of galactosylated cholesterol (β-GalChol), in addition to β-GlcChol. Analyses of brain tissues from GBA2-deficient mice and GBA1- and/or GBA2-deficient Japanese rice fish (Oryzias latipes) revealed that GBA1 and GBA2 are responsible for β-GlcChol degradation and formation, respectively, and that both GBA1 and GBA2 are responsible for β-GalChol formation. Liquid chromatography–tandem MS revealed that β-GlcChol and β-GalChol are present throughout development from embryo to adult in the mouse brain. We found that β-GalChol expression depends on galactosylceramide (GalCer), and developmental onset of β-GalChol biosynthesis appeared to be during myelination. We also found that β-GlcChol and β-GalChol are secreted from neurons and glial cells in association with exosomes. In vitro enzyme assays confirmed that GBA1 and GBA2 have transgalactosylation activity to transfer the galactose residue from GalCer to cholesterol to form β-GalChol. This is the first report of the existence of β-GalChol in vertebrates and how β-GlcChol and β-GalChol are formed in the brain.

The Government today said the first batch of subsidies amounting to $5.6 million under two relief measures for recyclers has been disbursed, while $5.6 million in subsidies had been approved under a management sector support scheme.

The two Recycling Fund measures aim to help the recycling industry cope with the current economic situation and recent operational difficulties arising from the COVID-19 epidemic.

The Advisory Committee on Recycling Fund announced in mid-March to reserve $100 million to launch the One-off Recycling Industry Anti-epidemic Scheme.

The scheme provides timely financial support to help with recyclers’ operational costs for six months. The funding limit for each recycler is $20,000 per month from January 1 to June 30, or $120,000 in total maximum subsidy.

The committee has also allocated additional funds to extend the earlier-launched One-off Rental Support Scheme for another six months, providing a total funding of $200 million to fight the virus and help the recycling industry ride out the difficult times.

The rental support scheme, which benefits street-corner recycling shops and recycling sites, originally ran from October to March. It has been extended for six months until September this year, totalling 12 months.

The monthly rental subsidy for each recycler is capped at $25,000, setting the maximum total rental subsidy at $300,000.

Separately, the Anti-epidemic Support Scheme for Property Management Sector has approved 205 applications involving around $5.6 million in subsidies to benefit more than 1,500 building blocks.

The relevant property management companies and owners’ organisations will receive notifications for subsidy disbursement shortly.

The list of properties for which applications have been approved is available online.

Briefing sessions were held earlier to introduce the scheme to the property management sector and owners’ organisations.

The Government today announced that the Environment Bureau has disbursed about $6.5 million in subsidies to 809 private municipal solid waste collectors by cheque.

Under the Government's latest round of anti-epidemic measures, the bureau launched the Subsidy Scheme for the Refuse Transfer Station Account Holders for Transporting Municipal Solid Waste to provide a one-off relief subsidy of $8,000 to each eligible private municipal solid waste collector.

To provide financial support to the industry as soon as possible, the Environmental Protection Department, following funding approval by the Legislative Council Finance Committee, expedited the subsidy disbursement arrangement by waiving the application procedures.

The cheques have been issued and posted to all eligible private collectors.

Eligible collectors are refuse transfer station account holders who transported municipal solid waste to refuse transfer stations or landfills in the first quarter of the year.

The subsidy will assist them in increasing resources to enhance workers' personal protective equipment and strengthen the disinfection of refuse transport vehicles to curb the risk of virus transmission and maintain environmental hygiene.

(Carnegie Mellon University) A new study developed a model of regulation in which the probability of a stricter standard being enacted increased with the proportion of firms in an industry that could meet the standard. The study found that regulations that consider the proportion of firms that can meet the new standard can motivate the development of a new green technology more effectively than regulations that do not consider this factor.

(University of Massachusetts Amherst) As physicians and families know too well, though Alzheimer's disease has been intensely studied for decades, too much is still not known about molecular processes in the brain that cause it. Now researchers at the University of Massachusetts Amherst say new insights from analytic theory and molecular simulation techniques offer a better understanding of amyloid fibril growth and brain pathology.

Bacteria secrete siderophores to access iron, a key nutrient poorly bioavailable and the source of strong competition between microorganisms in most biotopes. Many bacteria also use siderophores produced by other microorganisms (exosiderophores) in a piracy strategy. Pseudomonas aeruginosa, an opportunistic pathogen, produces two siderophores, pyoverdine and pyochelin, and is also able to use a panel of exosiderophores. We first investigated expression of the various iron-uptake pathways of P. aeruginosa in three different growth media using proteomic and RT-qPCR approaches and observed three different phenotypic patterns, indicating complex phenotypic plasticity in the expression of the various iron-uptake pathways. We then investigated the phenotypic plasticity of iron-uptake pathway expression in the presence of various exosiderophores (present individually or as a mixture) under planktonic growth conditions, as well as in an epithelial cell infection assay. In all growth conditions tested, catechol-type exosiderophores were clearly more efficient in inducing the expression of their corresponding transporters than the others, showing that bacteria opt for the use of catechol siderophores to access iron when they are present in the environment. In parallel, expression of the proteins of the pyochelin pathway was significantly repressed under most conditions tested, as well as that of proteins of the pyoverdine pathway, but to a lesser extent. There was no effect on the expression of the heme and ferrous uptake pathways. Overall, these data provide precise insights on how P. aeruginosa adjusts the expression of its various iron-uptake pathways (phenotypic plasticity and switching) to match varying levels of iron and competition.

The yeast protein Mpo1 belongs to a protein family that is widely conserved in bacteria, fungi, protozoa, and plants, and is the only protein of this family whose function has so far been elucidated. Mpo1 is an Fe²⁺-dependent dioxygenase that catalyzes the α-oxidation reaction of 2-hydroxy (2-OH) long-chain FAs produced in the degradation pathway of the long-chain base phytosphingosine. However, several biochemical characteristics of Mpo1, such as its catalytic residues, membrane topology, and substrate specificity, remain unclear. Here, we report that yeast Mpo1 contains two transmembrane domains and that both its N- and C-terminal regions are exposed to the cytosol. Mutational analyses revealed that three histidine residues conserved in the Mpo1 family are especially important for Mpo1 activity, suggesting that they may be responsible for the formation of coordinate bonds with Fe²⁺. We found that, in addition to activity toward 2-OH long-chain FAs, Mpo1 also exhibits activity toward 2-OH very-long-chain FAs derived from the FA moiety of sphingolipids. These results indicate that Mpo1 is involved in the metabolism of long-chain to very-long-chain 2-OH FAs produced in different pathways. We noted that the growth of mpo1 cells is delayed upon carbon deprivation, suggesting that the Mpo1-mediated conversion of 2-OH FAs to non-hydroxy FAs is important for utilizing 2-OH FAs as a carbon source under carbon starvation. Our findings help to elucidate the as-yet-unknown functions and activities of other Mpo1 family members.

The new American president will not be inaugurated until January 20. He will certainly face the most difficult economic conditions since Franklin Roosevelt entered the White House in March 1933. The politics of presidential transition – in this year, as seventy-six years ago – seem likely only to exacerbate the global crisis.

The race is on to ensure that relations between the United States and its European allies are set on the right track from the outset of Barack Obama’s presidency. Although they may not like it, the main responsibility for ensuring that the transatlantic relationship does not stumble into a series of disappointed expectations in its first critical year lies more in European capitals than in Washington.

HLA-DQA1 and -DQB1 are strongly associated with type 1 diabetes (T1D), and DQ8.1 and DQ2.5 are major risk haplotypes. Next generation targeted sequencing of HLA-DQA1 and -DQB1 in Swedish newly diagnosed 1-18 year-old patients (n=962) and controls (n=636) was used to construct abbreviated DQ haplotypes, converted into amino acid (AA) residues, and assessed for their associations with T1D. A hierarchically-organized haplotype (HOH) association analysis, allowed 45 unique DQ haplotypes to be categorized into seven clusters. The DQ8/9 cluster included two DQ8.1 risk and the DQ9 resistant haplotypes, and the DQ2 cluster, included the DQ2.5 risk and DQ2.2 resistant haplotypes. Within each cluster, HOH found residues α44Q (OR 3.29, p=2.38*10^-85 ) and β57A (OR 3.44, p=3.80*10^-84) to be associated with T1D in the DQ8/9 cluster representing all ten residues (α22, α23, α44, α49, α51, α53, α54, α73, α184, β57) due to complete linkage-disequilibrium (LD) of α44 with eight such residues. Within the DQ2 cluster and due to LD, HOH analysis found α44C and β135D to share the risk for T1D (OR 2.10, p=1.96*10^-20). The motif "QAD" of α44, β57, and β135 captured the T1D risk association of DQ8.1 (OR 3.44, p=3.80*10^-84), the corresponding motif "CAD" captured the risk association of DQ2.5 (OR 2.10, p=1.96*10^-20). Two risk associations were related to GADA and IA-2A, but in opposite directions. "CAD" was positively associated with GADA (OR 1.56; p=6.35*10^-8) but negatively with IA-2A (OR 0.59, p= 6.55*10^-11). "QAD" was negatively associated with GADA (OR 0.88; p= 3.70*10^-3) but positively with IA-2A (OR 1.64; p= 2.40*10^-14), despite a single difference at α44. The residues are found in and around anchor pockets 1 and 9, as potential TCR contacts, in the areas for CD4 binding and putative homodimer formation. The identification of three HLA-DQ AA (α44, β57, β135) conferring T1D risk should sharpen functional and translational studies.
