As 1 in 6 UK adults struggle with their mental health, is the rise in remote working making employees happier or creating a workforce racked by loneliness?

The violence and vandalism in recent months sparked a crisis of confidence of our rule of law. The so-called justice lawbreaking or civil disobedience is never justified under the law. I urge all of you not to engage in any illegal activities.

The Court of Final Appeal in its judgment (FACC8-10/2017) pointed out that: (1) unlawful assemblies involving violence, even a relatively low degree, will not be condoned and may justifiably attract sentences of immediate imprisonment in the future; and (2) little weight will be given to the mitigation that the offending act was committed in the exercise of constitutional rights or acts of civil disobedience because the fact of a conviction will necessarily mean the offender has crossed the line separating the lawful exercise of his constitutional rights from unlawful activity subject to sanctions and constraints.

There are suggestions that deliberate lawbreaking might be considered to achieve objectives, however, this would bring a wrong concept of the rule of law. The escalated violence and vandalism in the last few months have also undermined the perception of the rule of law among the public. My colleagues and I would promote and publicise the correct concept of the rule of law to the citizens through different channels. In analysing the current situation, I hope that we all could remain reasonable and objective by keeping an open mind, being informed and considering all relevant facts before coming to a conclusion.

Our rule of law has been highly regarded, and such an achievement was not easy to come by. We should all join hands to cherish and safeguard our rule of law. Abiding by the law is one of the many obligations that ought to be observed by the public. Law exists in practice but it should not only be practised by lawyers, judges and governments. More importantly, the rule of law should be observed and respected by the community as a whole. The Government would continue to be strongly committed to upholding the rule of law.

Secretary for Justice Teresa Cheng wrote this article and posted it on her blog on December 22.

To counter our adverse economic conditions, I have unveiled four sets of relief measures since last August. Totalling some $25 billion, the funds are focused on supporting businesses and lightening the burden weighing on the people of Hong Kong.

Meanwhile, we will continue to reach out to the community. Through wide-ranging dialogue communication and the pursuit of policies that address the deep-seated issues at the heart of our divide, I am hopeful that together we will find a path to peace and prosperity.

From an economic perspective, there is reason for optimism. I am heartened by the confidence private equity investors have shown in us. In the third quarter of 2019, some 560 private equity companies here managed US$153 billion.

We have nearly 50 more private equity (PE) firms based here when compared with the previous quarter. Among the world's top 10 PE fund managers, nine have a presence here in Hong Kong. That, ladies and gentlemen, underlines Hong Kong's formidable strengths in the Asian PE market. In that we trail only Mainland.

By channelling capital into corporations and startups in the innovation and technology field, PE and VC (venture capital) funds may well become as important as banks and IPO markets one day.

This Government is determined to help unlock the vast potential of the asset and wealth management business, because we believe you are critical to ensuring Hong Kong's status as one of the world's leading financial centres.

Fund-service centre 

That is why we have been stepping up efforts to sharpen Hong Kong's competitive edge on asset and wealth management through a multi-pronged approach including: (a) diversifying our fund structures and streamlining the licensing process to encourage fund formation; (b) adopting a more user-friendly approach to attract family offices; (c) providing a more facilitative tax environment for funds; and (d) expanding our fund distribution network through deepening our mutual access arrangements with other major financial markets.

On fund structure, the long-awaited, limited-partnership fund regime is close to reality, thanks in part to your favourable feedback. Indeed, we are now developing the necessary legislation. Because of the current filibustering at the Legislative Council, the tabling of the legislation got a little delayed, but it remains our top policy priority for the rest of this year to put this forward.

We are confident that the new regime will attract PE and VC funds, and we count on your support for that. With the new regime in place, we aim to bring in as many offshore funds as possible onshore to Hong Kong. We are well positioned to capture the opportunity arising from what happened on the international front over tax base erosion. This is mutually beneficial to Hong Kong as a fund hub and also the PE industry at large as you search for a new home for the funds you manage.

PE and VC funds, whether onshore or offshore, have enjoyed a profits tax exemption since last April. A tax-exempt fund can invest in local and overseas private companies. Hong Kong, by now, has a tax regime at fund level that is competitive and caters to the needs of the PE industry. I fully understand that resolving the tax issues at fund level is not enough in itself. It is of even greater importance to tackle head-on the tax arrangement for investment managers. This is a hard nut to crack, but one that I am determined to look into and come up with solutions that will strengthen Hong Kong's position as a leading fund hub with one of the most competitive tax arrangements for investment managers in the PE industry.

The significance of the limited partnership fund regime in completing Hong Kong's fund manufacturing infrastructure is underpinned by its precursor - the open-ended fund company regime. Since its operation in July 2018, a number of open-ended fund companies have sprouted. The SFC (Securities & Futures Commission) is also looking into how to make the regime more business-friendly to facilitate the take-up.

In short, the Government and our regulators are committed to developing Hong Kong into a full-fledged fund-service centre.

We are equally intent on expanding our fund-distribution network. We continue to expand our Mutual Recognition of Funds arrangements. Last year, Luxembourg and the Netherlands joined existing partners, the Mainland, Switzerland, France and the United Kingdom. More international partnerships will follow.

Family offices
Hong Kong is also an ideal location for the establishment of family offices, and we are boosting our promotional efforts in this regard.

The Hong Kong Monetary Authority and InvestHK will provide comprehensive services to attract family offices to Hong Kong. The SFC has also recently issued licensing guidance for PE firms and family offices. This will enhance clarity and would help address the industry's concerns.

Without a steady flow of talented professionals, of course, we will not be able to cash in on all the opportunities there for us. That is why the Government's Pilot Programme to Enhance Talent Training for the Asset & Wealth Management Sector has been supporting the industry since 2016.

I encourage you to offer exposure, opportunity and jobs for our youth. To give them a stake in the society through the programme.

Business bridge 

Zooming out a bit, the Government will continue to boost Hong Kong's singular advantage as the business and financial bridge between international markets and investors and their counterparts on the Mainland.

To that end, we continue to emphasise the established channels - our Stock Connects, Bond Connect and the Mutual Recognition of Funds arrangements. We will also strengthen our position as the global offshore Renminbi business hub.

Then there is the Guangdong-Hong Kong-Macao Greater Bay Area Development, and the extraordinary opportunity that it presents to Hong Kong.

With a GDP in excess of US$1.6 trillion and more than 70 million prosperous consumers, the Greater Bay Area presents vast potential for the asset and wealth management sector. For each and every one of you. The establishment of a Greater Bay Area wealth-management connect scheme, which was, as you know, recently announced, will go a long way towards realising that promise.

Our regulators are working out the details with their counterparts on the Mainland, and we will keep you posted and we are determined to push that forward as soon as possible.

Case Studies

Following its evoked release, dopamine (DA) signaling is rapidly terminated by presynaptic reuptake, mediated by the cocaine-sensitive DA transporter (DAT). DAT surface availability is dynamically regulated by endocytic trafficking, and direct protein kinase C (PKC) activation acutely diminishes DAT surface expression by accelerating DAT internalization. Previous cell line studies demonstrated that PKC-stimulated DAT endocytosis requires both Ack1 inactivation, which releases a DAT-specific endocytic brake, and the neuronal GTPase, Rit2, which binds DAT. However, it is unknown whether Rit2 is required for PKC-stimulated DAT endocytosis in DAergic terminals or whether there are region- and/or sex-dependent differences in PKC-stimulated DAT trafficking. Moreover, the mechanisms by which Rit2 controls PKC-stimulated DAT endocytosis are unknown. Here, we directly examined these important questions. Ex vivo studies revealed that PKC activation acutely decreased DAT surface expression selectively in ventral, but not dorsal, striatum. AAV-mediated, conditional Rit2 knockdown in DAergic neurons impacted baseline DAT surface:intracellular distribution in DAergic terminals from female ventral, but not dorsal, striatum. Further, Rit2 was required for PKC-stimulated DAT internalization in both male and female ventral striatum. FRET and surface pulldown studies in cell lines revealed that PKC activation drives DAT-Rit2 surface dissociation and that the DAT N terminus is required for both PKC-mediated DAT-Rit2 dissociation and DAT internalization. Finally, we found that Rit2 and Ack1 independently converge on DAT to facilitate PKC-stimulated DAT endocytosis. Together, our data provide greater insight into mechanisms that mediate PKC-regulated DAT internalization and reveal unexpected region-specific differences in PKC-stimulated DAT trafficking in bona fide DAergic terminals.

Lens proteins become increasingly cross-linked through nondisulfide linkages during aging and cataract formation. One mechanism that has been implicated in this cross-linking is glycation through formation of advanced glycation end products (AGEs). Here, we found an age-associated increase in stiffness in human lenses that was directly correlated with levels of protein–cross-linking AGEs. α-Crystallin in the lens binds to other proteins and prevents their denaturation and aggregation through its chaperone-like activity. Using a FRET-based assay, we examined the stability of the αA-crystallin–γD-crystallin complex for up to 12 days and observed that this complex is stable in PBS and upon incubation with human lens–epithelial cell lysate or lens homogenate. Addition of 2 mm ATP to the lysate or homogenate did not decrease the stability of the complex. We also generated complexes of human αA-crystallin or αB-crystallin with alcohol dehydrogenase or citrate synthase by applying thermal stress. Upon glycation under physiological conditions, the chaperone–client complexes underwent greater extents of cross-linking than did uncomplexed protein mixtures. LC-MS/MS analyses revealed that the levels of cross-linking AGEs were significantly higher in the glycated chaperone–client complexes than in glycated but uncomplexed protein mixtures. Mouse lenses subjected to thermal stress followed by glycation lost resilience more extensively than lenses subjected to thermal stress or glycation alone, and this loss was accompanied by higher protein cross-linking and higher cross-linking AGE levels. These results uncover a protein cross-linking mechanism in the lens and suggest that AGE-mediated cross-linking of α-crystallin–client complexes could contribute to lens aging and presbyopia.

Cas12a (Cpf1) is an RNA-guided endonuclease in the bacterial type V-A CRISPR-Cas anti-phage immune system that can be repurposed for genome editing. Cas12a can bind and cut dsDNA targets with high specificity in vivo, making it an ideal candidate for expanding the arsenal of enzymes used in precise genome editing. However, this reported high specificity contradicts Cas12a's natural role as an immune effector against rapidly evolving phages. Here, we employed high-throughput in vitro cleavage assays to determine and compare the native cleavage specificities and activities of three different natural Cas12a orthologs (FnCas12a, LbCas12a, and AsCas12a). Surprisingly, we observed pervasive sequence-specific nicking of randomized target libraries, with strong nicking of DNA sequences containing up to four mismatches in the Cas12a-targeted DNA-RNA hybrid sequences. We also found that these nicking and cleavage activities depend on mismatch type and position and vary with Cas12a ortholog and CRISPR RNA sequence. Our analysis further revealed robust nonspecific nicking of dsDNA when Cas12a is activated by binding to a target DNA. Together, our findings reveal that Cas12a has multiple nicking activities against dsDNA substrates and that these activities vary among different Cas12a orthologs.

Prominins (proms) are transmembrane glycoproteins conserved throughout the animal kingdom. They are associated with plasma membrane protrusions, such as primary cilia, as well as extracellular vesicles derived thereof. Primary cilia host numerous signaling pathways affected in diseases known as ciliopathies. Human PROM1 (CD133) is detected in both somatic and cancer stem cells and is also expressed in terminally differentiated epithelial and photoreceptor cells. Genetic mutations in the PROM1 gene result in retinal degeneration by impairing the proper formation of the outer segment of photoreceptors, a modified cilium. Here, we investigated the impact of proms on two distinct examples of ciliogenesis. First, we demonstrate that the overexpression of a dominant-negative mutant variant of human PROM1 (i.e. mutation Y819F/Y828F) significantly decreases ciliary length in Madin–Darby canine kidney cells. These results contrast strongly to the previously observed enhancing effect of WT PROM1 on ciliary length. Mechanistically, the mutation impeded the interaction of PROM1 with ADP-ribosylation factor–like protein 13B, a key regulator of ciliary length. Second, we observed that in vivo knockdown of prom3 in zebrafish alters the number and length of monocilia in the Kupffer's vesicle, resulting in molecular and anatomical defects in the left-right asymmetry. These distinct loss-of-function approaches in two biological systems reveal that prom proteins are critical for the integrity and function of cilia. Our data provide new insights into ciliogenesis and might be of particular interest for investigations of the etiologies of ciliopathies.

(Columbia University's Mailman School of Public Health) Researchers found that 92 percent of employers who responded to a survey on climate change and public health reported need for public health professionals with training in climate change will very likely increase in the next 5 to 10 years. While graduates of public health programs who focus on climate change are in demand in the current job market, these positions appear to be just a small proportion of the total number of jobs available in public health.

Chief Justice Patience Roggensack faced backlash for her comment, with some people calling it "elitist" to separate meatpackers from "regular folks."

Now Swain, 40, spends her evenings having dinner with her girls, age 5 and 8, and studying for her real-estate license, which she hopes will provide more long-term stability for her family after the coronavirus crisis upended her livelihood. "I can't be put in a position like this again," said Swain, a bartender for 20 years. American women are taking an outsized hit from the early wave of unemployment caused by the pandemic, due to the nature of the jobs that were lost in the business shutdowns to control the spread of the coronavirus.

Acute myocardial infarction (MI) triggers a local and systemic inflammatory response. We recently showed microglia involvement using TSPO imaging. Here, we evaluate whether ¹¹C-methionine provides further insights into heart-brain inflammation networking. Methods: Male Bl6N mice underwent permanent coronary artery ligation followed by ¹¹C-methionine PET at 3 and 7 days (n = 3). In subgroups, leukocyte homing was blocked by integrin antibodies (n = 5). The cellular substrate for PET signal was identified using brain section immunostaining. Results: ¹¹C-methionine uptake peaked in the MI region at d3 (5.9±0.9vs 2.4±0.5 %ID/cc), decreasing to control level by d7 (4.3±0.6 %ID/cc). Brain uptake was proportional to cardiac uptake (r=0.47,p<0.05), peaking also at d3 (2.9±0.4vs 2.4±0.3 %ID/cc) and returning to baseline at d7 (2.3±0.4 %ID/cc). Integrin blockade reduced uptake at every time point. Immunostaining at d3 revealed co-localization of the L-type amino acid transporter with GFAP-positive astrocytes but not CD68-positive microglia. Conclusion: PET imaging with ¹¹C-methionine specifically identifies an astrocyte component, enabling further dissection of the heart-brain axis in post MI inflammation.

Rationale: The effects of tobacco smoking on the brain’s immune system are not well elucidated. While nicotine is immunosuppressive, other constituents in tobacco smoke have inflammatory effects. Positron Emission Tomography (PET) imaging of the 18-kDa translocator protein (TSPO) provide a biomarker for microglia, the brain’s primary immunocompetent cells. This work compared brain TSPO levels in 20 tobacco smokers (abstinent for at least 2 hours) and 20 nonsmokers using a fully quantitative modeling approach for the first time. Methods: [¹¹C]PBR28 PET scans were acquired with arterial blood sampling to estimate the metabolite-corrected input function. [¹¹C]PBR28 volumes of distribution (V_T) were estimated throughout the brain with multilinear analysis. Results: Statistical analyses revealed no evidence for significant differences in regional [¹¹C]PBR28 V_T between smokers and non-smokers (whole-brain Cohen’s d=0.09) despite adequate power to detect medium effect sizes. Conclusion: These findings inform previous PET studies reporting lower TSPO radiotracer concentrations in brain (measured as standardized uptake value, SUV) of tobacco smokers compared to nonsmokers by demonstrating the importance of accounting for radiotracer concentrations in plasma. These findings suggest that compared to nonsmokers, smokers have comparable TSPO levels in brain. Additional work with other biomarkers is needed to fully characterize effects of tobacco smoking on the brain’s immune system.

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 respiratory epithelium comprises polarized cells at the interface between the environment and airway tissues. Polarized apical and basolateral protein secretions are a feature of airway epithelium homeostasis. Human respiratory syncytial virus (hRSV) is a major human pathogen that primarily targets the respiratory epithelium. However, the consequences of hRSV infection on epithelium secretome polarity and content remain poorly understood. To investigate the hRSV-associated apical and basolateral secretomes, a proteomics approach was combined with an ex vivo pediatric human airway epithelial (HAE) model of hRSV infection (data are available via ProteomeXchange and can be accessed at https://www.ebi.ac.uk/pride/ with identifier PXD013661). Following infection, a skewing of apical/basolateral abundance ratios was identified for several individual proteins. Novel modulators of neutrophil and lymphocyte activation (CXCL6, CSF3, SECTM1 or CXCL16), and antiviral proteins (BST2 or CEACAM1) were detected in infected, but not in uninfected cultures. Importantly, CXCL6, CXCL16, CSF3 were also detected in nasopharyngeal aspirates (NPA) from hRSV-infected infants but not healthy controls. Furthermore, the antiviral activity of CEACAM1 against RSV was confirmed in vitro using BEAS-2B cells. hRSV infection disrupted the polarity of the pediatric respiratory epithelial secretome and was associated with immune modulating proteins (CXCL6, CXCL16, CSF3) never linked with this virus before. In addition, the antiviral activity of CEACAM1 against hRSV had also never been previously characterized. This study, therefore, provides novel insights into RSV pathogenesis and endogenous antiviral responses in pediatric airway epithelium.
