Objective

To determine the contributions of apraxia of speech (AOS) and anomia to conversational dysfluency.

Methods

In this observational study of 52 patients with chronic aphasia, 47 with concomitant AOS, fluency was quantified using correct information units per minute (CIUs/min) from propositional speech tasks. Videos of patients performing conversational, how-to and picture-description tasks, word and sentence repetition, and diadochokinetic tasks were used to diagnose AOS using the Apraxia of Speech Rating Scale (ASRS). Anomia was quantified by patients' scores on the 30 even-numbered items from the Boston Naming Test (BNT).

Results

Together, ASRS and BNT scores accounted for 51.4% of the total variance in CIUs/min; the ASRS score accounted for the majority of that variance. The BNT score was associated with lesions in the left superior temporal gyrus, left inferior frontal gyrus, and large parts of the insula. The global ASRS score was associated with lesions in the left dorsal arcuate fasciculus (AF), pre- and post-central gyri, and both banks of the central sulcus of the insula. The ASRS score for the primary distinguishing features of AOS (no overlap with features of aphasia) was associated with less AF and more insular involvement. Only ~27% of this apraxia-specific lesion overlapped with lesions associated with the BNT score. Lesions associated with AOS had minimal overlap with the frontal aslant tract (FAT) (<1%) or the extreme capsule fiber tract (1.4%). Finally, ASRS scores correlated significantly with damage to the insula but not to the AF, extreme capsule, or FAT.

Conclusions

Results are consistent with previous findings identifying lesions of the insula and AF in patients with AOS, damage to both of which may create dysfluency in patients with aphasia.

Objective

To investigate the frequency of levodopa-induced dyskinesia in dementia with Lewy bodies (DLBs) and Parkinson disease with dementia (PDD) and compare these frequencies with patients with incident Parkinson disease (PD) through a population-based cohort study.

Methods

We identified all patients with DLB, PDD, and PD without dementia in a 1991–2010 population-based parkinsonism-incident cohort, in Olmsted County, Minnesota. We abstracted information about levodopa-induced dyskinesia. We compared patients with DLB and PDD with dyskinesia with patients with PD from the same cohort.

Results

Levodopa use and dyskinesia data were available for 141/143 (98.6%) patients with a diagnosis of either DLB or PDD; 87 (61.7%), treated with levodopa. Dyskinesia was documented in 12.6% (8 DLB and 3 PDD) of levodopa-treated patients. Among these patients, median parkinsonism diagnosis age was 74 years (range: 64–80 years); 63.6%, male. The median interval from levodopa initiation to dyskinesia onset was 2 years (range: 3 months–4 years); the median daily levodopa dosage was 600 mg (range: 50–1,600 mg). Dyskinesia severity led to levodopa adjustments in 5 patients, and all improved. Patients with dyskinesia were diagnosed with parkinsonism at a significantly younger age compared with patients without dyskinesia (p < 0.001). Levodopa dosage was unrelated to increased risk of dyskinesias among DLB and PDD. In contrast, 30.1% of levodopa-treated patients with PD developed dyskinesia. In age-, sex-, and levodopa dosage–adjusted models, Patients with DLB and PDD each had lower odds of developing dyskinesia than patients with PD (odds ratio = 0.42, 95% CI 0.21–0.88; p = 0.02).

Conclusions

The dyskinesia risk for levodopa-treated patients with DLB or PDD was substantially less than for levodopa-treated patients with PD.

Many complex human traits exhibit differences between sexes. While numerous factors likely contribute to this phenomenon, growing evidence from genome-wide studies suggest a partial explanation: that males and females from the same population possess differing genetic architectures. Despite this, mapping gene-by-sex (GxS) interactions remains a challenge likely because the magnitude of such an interaction is typically and exceedingly small; traditional genome-wide association techniques may be underpowered to detect such events, due partly to the burden of multiple test correction. Here, we developed a local Bayesian regression (LBR) method to estimate sex-specific SNP marker effects after fully accounting for local linkage-disequilibrium (LD) patterns. This enabled us to infer sex-specific effects and GxS interactions either at the single SNP level, or by aggregating the effects of multiple SNPs to make inferences at the level of small LD-based regions. Using simulations in which there was imperfect LD between SNPs and causal variants, we showed that aggregating sex-specific marker effects with LBR provides improved power and resolution to detect GxS interactions over traditional single-SNP-based tests. When using LBR to analyze traits from the UK Biobank, we detected a relatively large GxS interaction impacting bone mineral density within ABO, and replicated many previously detected large-magnitude GxS interactions impacting waist-to-hip ratio. We also discovered many new GxS interactions impacting such traits as height and body mass index (BMI) within regions of the genome where both male- and female-specific effects explain a small proportion of phenotypic variance (R² < 1 x 10^–4), but are enriched in known expression quantitative trait loci.

During meiotic prophase, concurrent transcription, recombination, and chromosome synapsis place substantial topological strain on chromosomal DNA, but the role of topoisomerases in this context remains poorly defined. Here, we analyzed the roles of topoisomerases I and II (Top1 and Top2) during meiotic prophase in Saccharomyces cerevisiae. We show that both topoisomerases accumulate primarily in promoter-containing intergenic regions of actively transcribing genes, including many meiotic double-strand break (DSB) hotspots. Despite the comparable binding patterns, top1 and top2 mutations have different effects on meiotic recombination. TOP1 disruption delays DSB induction and shortens the window of DSB accumulation by an unknown mechanism. By contrast, temperature-sensitive top2-1 mutants exhibit a marked delay in meiotic chromosome remodeling and elevated DSB signals on synapsed chromosomes. The problems in chromosome remodeling were linked to altered Top2 binding patterns rather than a loss of Top2 catalytic activity, and stemmed from a defect in recruiting the chromosome remodeler Pch2/TRIP13 to synapsed chromosomes. No chromosomal defects were observed in the absence of TOP1. Our results imply independent roles for Top1 and Top2 in modulating meiotic chromosome structure and recombination.

Synesthesia is a neurologic trait in which specific inducers, such as sounds, automatically elicit additional idiosyncratic percepts, such as color (thus “colored hearing”). One explanation for this trait—and the one tested here—is that synesthesia results from unusually weak pruning of cortical synaptic hyperconnectivity during early perceptual development. We tested the...

As yet, very few vaccine candidates with activity in animals against Mycobacterium tuberculosis infection have been tested as therapeutic postexposure vaccines. We recently described two pools of mycobacterial proteins with this activity, and here we describe further studies in which four of these proteins (Rv1738, Rv2032, Rv3130, and Rv3841) were generated as a fusion polypeptide and then delivered in a novel yeast-based platform (Tarmogen) which itself has immunostimulatory properties, including activation of Toll-like receptors. This platform can deliver antigens into both the class I and class II antigen presentation pathways and stimulate strong Th1 and Th17 responses. In mice this fusion vaccine, designated GI-19007, was immunogenic and elicited strong gamma interferon (IFN-) and interleukin-17 (IL-17) responses; despite this, they displayed minimal prophylactic activity in mice that were subsequently infected with a virulent clinical strain. In contrast, in a therapeutic model in the guinea pig, GI-19007 significantly reduced the lung bacterial load and reduced lung pathology, particularly in terms of secondary lesion development, while significantly improving survival in one-third of these animals. In further studies in which guinea pigs were vaccinated with BCG before challenge, therapeutic vaccination with GI-19007 initially improved survival versus that of animals given BCG alone, although this protective effect was gradually lost at around 400 days after challenge. Given its apparent ability to substantially limit bacterial dissemination within and from the lungs, GI-19007 potentially can be used to limit lung damage as well as facilitating chemotherapeutic regimens in infected individuals.

We investigated whether cycloheximide (CHX) would induce amnesia for the stress-induced impairment of extinction retrieval. First, a single restraint stress session was demonstrated to impair extinction retrieval, but not fear conditioning. A second experiment showed that when CHX was administered immediately after restraint, rats exhibited significant extinction retrieval at test (i.e., retrograde amnesia for the stress). In a third experiment, the stress session impaired various amounts of extinction durations, suggesting that the stress inhibited extinction retrieval rather than enhancing the original fear learning. These results suggest memories for acute stress are susceptible to disruption, which could have clinical implications.

The ESCRT-III protein complex executes reverse-topology membrane scission. The scission mechanism is unclear but is linked to remodeling of ESCRT-III complexes at the membrane surface. At endosomes, ESCRT-III mediates the budding of intralumenal vesicles (ILVs). In Saccharomyces cerevisiae, ESCRT-III activity at endosomes is regulated through an unknown mechanism by Doa4, an ubiquitin hydrolase that deubiquitylates transmembrane proteins sorted into ILVs. We report that the non-catalytic N-terminus of Doa4 binds Snf7, the predominant ESCRT-III subunit. Through this interaction, Doa4 overexpression alters Snf7 assembly status and inhibits ILV membrane scission. In vitro, the Doa4 N-terminus inhibits association of Snf7 with Vps2, which functions with Vps24 to arrest Snf7 polymerization and remodel Snf7 polymer structure. In vivo, Doa4 overexpression inhibits Snf7 interaction with Vps2 and also with the ATPase Vps4, which is recruited by Vps2 and Vps24 to remodel ESCRT-III complexes by catalyzing subunit turnover. Our data suggest a mechanism by which the deubiquitylation machinery regulates ILV biogenesis by interfering with ESCRT-III remodeling.

Previously, we have shown that bulk microtubule (MT) movement correlates with neurite elongation, and blocking either dynein activity or MT assembly inhibits both processes. However, whether the contributions of MT dynamics and dynein activity to neurite elongation are separate or interdependent is unclear. Here, we investigated the underlying mechanism by testing the roles of dynein and MT assembly in neurite elongation of Aplysia and chick neurites using time-lapse imaging, fluorescent speckle microscopy, super-resolution imaging and biophysical analysis. Pharmacologically inhibiting either dynein activity or MT assembly reduced neurite elongation rates as well as bulk and individual MT anterograde translocation. Simultaneously suppressing both processes did not have additive effects, suggesting a shared mechanism of action. Single-molecule switching nanoscopy revealed that inhibition of MT assembly decreased the association of dynein with MTs. Finally, inhibiting MT assembly prevented the rise in tension induced by dynein inhibition. Taken together, our results suggest that MT assembly is required for dynein-driven MT translocation and neurite outgrowth.

A new larger benthic porcelaneous foraminifer of soritid affinity is described as Tarburina zagrosiana n. gen., n. sp. from the late Maastrichtian of the Tarbur Formation, Zagros Zone, SW Iran. It occurs in foraminiferal–dasycladalean wackestones and packstones, in association with Loftusia ssp., dicyclinids/cuneolinids, Neobalkhania bignoti Cherchi & Schroeder, Gyroconulina columellifera Schroeder & Darmoian, Spirolina? farsiana Schlagintweit & Rashidi, Broeckina cf. dufrenoyi (d'Archiac), other benthic foraminifers, and dasycladalean algae. Due to its elongate test and marginal chamber subdivision by aligned vertical partitions, Tarburina n. gen. can be compared with representatives of the Praerhapydionininae. The interio-marginal slit-like foramina/aperture of Tarburina represents an outstanding feature in complex porcelaneous taxa. The monospecific genus Tarburina is considered a Maastrichtian newcomer within the Late Cretaceous Global Community Maturation cycle of larger benthic foraminifera. A biostratigraphic and palaeobiogeographical restriction seems possible, as reported for many other Late Cretaceous larger benthic foraminifera.

Background:

Asian Americans are at higher risk for noncardia gastric cancers (NCGC) relative to non-Hispanic Whites (NHW). Asian Americans are genetically, linguistically, and culturally heterogeneous, yet have mostly been treated as a single population in prior studies. This aggregation may obscure important subgroup-specific cancer patterns.

Methods:

We utilized data from 13 regional United States cancer registries from 1990 to 2014 to determine secular trends in incidence and survivorship from NCGC. Data were analyzed for NHWs and the six largest Asian American subgroups: Chinese, Japanese, Filipino, Korean, Vietnamese, and South Asian (Indian/Pakistani).

Results:

There exists substantial heterogeneity in NCGC incidence between Asian subgroups, with Koreans (48.6 per 100,000 person-years) having seven-fold higher age-adjusted incidence than South Asians (7.4 per 100,000 person-years). Asians had generally earlier stages of diagnosis and higher rates of surgical resection compared with NHWs. All Asian subgroups also demonstrated higher 5-year observed survival compared with NHWs, with Koreans (41.3%) and South Asians (42.8%) having survival double that of NHWs (20.1%, P < 0.001). In multivariable regression, differences in stage of diagnosis and rates of resection partially explained the difference in survivorship between Asian subgroups.

Conclusions:

We find substantial differences in incidence, staging, histology, treatment, and survivorship from NCGC between Asian subgroups, data which challenge our traditional perceptions about gastric cancer in Asians. Both biological heterogeneity and cultural/environmental differences may underlie these findings.

Impact:

These data are relevant to the national discourse regarding the appropriate role of gastric cancer screening, and identifies high-risk racial/ethnic subgroups who many benefit from customized risk attenuation programs.

GAZIANTEP, Turkey—After five years fighting to preserve Bashar al-Assad’s regime in Syria, Russia now appears inclined to dispose of its infamous client. Assad’s persistent brutality and corruption, and his inability to establish even the semblance of a functioning state, has grown to be a burden Moscow would prefer not to bear.

And then there’s the problem of Iran. Assad, members of his family, and his Alawite clansmen enjoy close, perhaps unbreakable, bonds to the regime in Tehran and to Iranian-backed militias in Syria. All of which undermines Moscow’s primary mission there: to rehabilitate the Assad regime as a symbol of stability capable of attracting hundreds of billions of dollars of foreign investment for reconstruction, which Russian firms would then be poised to receive. 

As long as Assad’s relatives continue to function as a mafia and give free rein to Iranian troops using Syria as base of operations to threaten Israel and plan attacks against U.S. troops in Iraq, those countries likely to foot the bill for Syrian reconstruction—the nations of Europe and the Gulf—are unlikely to come up with the cash.

Alan Yang’s film about the lack of understanding between generations strikes a chord, and is so relevant as coronavirus racism spreads

Inflamed by President Trump’s casual phrase “Chinese virus”, anti-Asian sentiment is erupting all over the world. As a British-Vietnamese person who has been spat on because of the colour of her skin, the film Tigertail is a glimmer of hope – a way of showing the truth, and connecting Asian communities at a time when panic and misinformation serve to break us apart. Alan Yang’s multi-generational love story Tigertail weaves in Yang’s cultural self-discovery and features memories of Taiwan, as experienced by the protagonist Pin-Jui. Weighted against the present tide of anti-Asian bigotry, this tender story about honesty and lost love is more relevant than ever.

“American culture has been negligent in portraying Asian-American people as fully realised human beings,” Yang told the Deadline podcast. Yang, who worked on Parks and Recreation before co-creating Master of None, recalled the trepidation he felt in the early days of his career, in a cultural landscape where east Asians were rarely represented, or stereotyped as hardworking automatons. Yang said he had felt restricted to using only white characters in his early pilots, fearing that all-Asian or Asian-American scripts would never be accepted. But this was before the film successes of Crazy Rich Asians, The Farewell and Parasite brought real Asian faces to mainstream culture.

The US believes Russia is working with Syrian President, Bashar al-Assad, to send militia fighters and equipment to Libya, according to senior officials. Speaking to reporters on Thursday, US special envoy for Syria, Jim Jeffrey, said Libya’s increasingly shadowy battlefield could get even more complicated. “We know that, certainly, the Russians are working with Assad to transfer militia fighters, possibly third country, possibly Syrian, to Libya, as well as equipment,” he said. His comments came a day after a leaked UN report confirmed the presence of Russian and Syrian mercenaries operating in Libya in support of renegade military commander, Khalifa Haftar. The report revealed that Russian private military contractor, Wagner Group, has up to 1,200 mercenaries operating in Libya in support of General Haftar’s forces, which are already backed by the UAE, Russia and Egypt. The report, seen by Reuters, is one of the first indications of the scale of Wagner’s military operation in Libya’s messy battlefield, as well as the first time the UN has confirmed the presence of the shadowy Russian mercenaries. Since 2014, the oil-rich North African country has been split between areas controlled by the internationally recognised Government of National Accord in Tripoli and the northwest, and territory held by Gen Haftar’s eastern-based forces in Benghazi. For almost six years Gen Haftar’s forces have been at war with a coalition of militias from the west of the country who support the government in Tripoli. Turkey is the only military backer of the Tripoli government that is currently trying to stave off Haftar’s year-long offensive on the capital. The UAE and Egypt have long strengthened Haftar’s forces with military equipment, including aircraft and helicopters, while Moscow provided private contractor forces. As the conflict has drawn on and involvement has increasingly become the stage for a struggle for power in the region, diplomats say both Turkey and the UAE have deployed drones and the use of mercenaries has increased, now seemingly including forces from Russia and Syria. Libya has been mired in chaos since a 2011 NATO intervention helped topple Colonel Muammar Gaddafi, and its battlefields increasingly populated with foreign fighters in a shadow-war. Russian mercenaries were first reported fighting alongside General Haftar’s forces in Libya in 2018. Vladimir Putin, the Russian president, however, insisted that those mercenaries do not represent the Russian government. Yet when General Haftar visited Moscow in 2018, Yevgeny Prigozhin, a businessman with long-standing ties to Mr Putin and suspected owner of Wagner, was seen in the footage of the meeting, sitting near the Russian defence minister. Russia, which also backs Assad’s government in Syria, has maintained a delicate balancing act in Libya, forging ties with both the UN-recognised government and with the rebel commander. But Moscow’s patience with General Haftar began to run out earlier this year when he and his entourage in January abruptly left the much-anticipated cease-fire talks in Moscow mediated by Russia and Turkey without signing the deal. Henry Wooster, deputy assistant secretary at State Department’s Bureau of Near Eastern Affairs also expressed increasing concern over the ties between the Libyan commander and Syria’s president, who are both bitter enemies of Turkey and fighting Turkish-backed militant groups on their soil. “Haftar’s establishment of so-called diplomatic relations with the Assad regime...is very much a part of the piece of the question of Syrian mercenaries, at least on his side of the equation,” he said. While the leaked report also confirmed the presence of Syrian mercenaries in Libya fighting alongside Haftar’s forces, Pro-Turkish Syrians are also known to be fighting with the Tripoli government, against General Haftar.

Russian President Vladimir Putin marked Victory Day, the anniversary of the defeat of Nazi Germany in World War II, in a ceremony shorn of its usual military parade and pomp by the coronavirus pandemic. In neighboring Belarus, however, the ceremonies went ahead in full, with tens of thousands of people in the sort of proximity that has been almost unseen in the world for months. Victory Day is Russia’s most important secular holiday and this year’s observance had been expected to be especially large because it is the 75th anniversary, but the Red Square military parade and a mass procession called The Immortal Regiment were postponed as part of measures to stifle the spread of the virus.

President Vladimir Putin told Russians they are "invincible" when they stand together as the country on Saturday marked the 75th anniversary of the end of World War II in lockdown from the coronavirus. With cases surging and authorities urging Russians to stay in their homes, celebrations of this year's Victory Day were muted after the Kremlin grudgingly postponed plans for a grand parade with world leaders. Instead of columns of military hardware and thousands of troops marching through Red Square as planned, Putin walked alone to lay flowers at the Eternal Flame outside the red brick walls of the Kremlin.

Cancellation of the ceremony was the second blow to Putin, who was forced to call off a referendum extending his time in power.
