The velocity of settling particles is an important determinant of distribution in extinct and extant species with passive dispersal mechanisms, such as plants, corals and phytoplankton. Here, we adapted dynamic scaling, borrowed from engineering, to determine settling velocity. Dynamic scaling leverages physical models with relevant dimensionless numbers matched to achieve similar dynamics to the original object. Previous studies have used flumes, wind tunnels or towed models to examine fluid flow around objects with known velocities. Our novel application uses free-falling models to determine the unknown sinking velocity of planktonic Foraminifera - organisms important to our understanding of the Earth's current and historic climate. Using enlarged 3D printed models of microscopic Foraminifera tests, sunk in viscous mineral oil to match their Reynolds numbers and drag coefficients, we predicted sinking velocity of real tests in seawater. This method can be applied to study other settling particles such as plankton, spores or seeds.The natural scale of insect navigation during foraging makes it challenging to study under controlled conditions. Virtual reality and trackball setups have offered experimental control over visual environments while studying tethered insects, but potential limitations and confounds introduced by tethering motivates the development of alternative untethered solutions. In this paper, we validate the use of a motion compensator (or 'treadmill') to study visually driven behaviour of freely moving wood ants (Formica rufa). We show how this setup allows naturalistic walking behaviour and preserves foraging motivation over long time frames. Furthermore, we show that ants are able to transfer associative and navigational memories from classical maze and arena contexts to our treadmill. Thus, we demonstrate the possibility to study navigational behaviour over ecologically relevant durations (and virtual distances) in precisely controlled environments, bridging the gap between natural and highly controlled laboratory experiments.The use of acoustics in predator evasion is a widely reported phenomenon amongst invertebrate taxa, but the study of ultrasonic anti-predator acoustics is often limited to the prey of bats. Here, we describe the acoustic function and morphology of a unique stridulatory structure - the Ander's organ - in the relict orthopteran Cyphoderris monstrosa (Ensifera, Hagloidea). This species is one of just eight remaining members of the family Prophalangopsidae, a group with a fossil record of over 90 extinct species widespread during the Jurassic period. We reveal that the sound produced by this organ has the characteristics of a broadband ultrasonic anti-predator defence, with a peak frequency of 58±15.5 kHz and a bandwidth of 50 kHz (at 10 dB below peak). Evidence from sexual dimorphism, knowledge on hearing capabilities and assessment of local predators, suggests that the signal likely targets ground-dwelling predators. Additionally, we reveal a previously undescribed series of cavities underneath the organ that probably function as a mechanism for ultrasound amplification. Morphological structures homologous in both appearance and anatomical location to the Ander's organ are observed to varying degrees in 4 of the 7 other extant members of this family, with the remaining 3 yet to be assessed. Therefore, we suggest that such structures may either be more widely present in this ancient family than previously assumed, or have evolved to serve a key function in the long-term survival of these few species, allowing them to outlive their extinct counterparts.Exposure to house dust mite (HDM) is highly associated with the development of allergic asthma. The adaptive immune response to HDM is largely Th2 and Th17 dominant, and a number of innate immune receptors have been identified that recognize HDM to initiate these responses. Nucleotide-binding oligomerization domain-containing protein 2 (NOD2) is a cytosolic sensor of peptidoglycan, which is important for Th2 and Th17 polarization. NOD2 mediates its signaling through its downstream effector kinase, receptor-interacting serine/threonine protein kinase 2 (RIP2). R-848 We have previously shown that RIP2 promotes HDM-associated allergic airway inflammation and Th2 and Th17 immunity, acting early in the HDM response and likely within airway epithelial cells. However, the consequences of inhibiting RIP2 during this critical period has not yet been examined. In this study, we pharmacologically inhibited RIP2 activity during the initial exposure to allergen in an acute HDM model of asthma and determined the effect on the subsequent development of allergic airway disease. We show that early inhibition of RIP2 was sufficient to reduce lung histopathology and local airway inflammation while reducing the Th2 immune response. Using a chronic HDM asthma model, we demonstrate that inhibition of RIP2, despite attenuating airway inflammation and airway remodeling, was insufficient to reduce airway hyperresponsiveness. These data demonstrate the potential of pharmacological targeting of this kinase in asthma and support further development and optimization of RIP2-targeted therapies.Lasting immunity following SARS-CoV-2 infection is questioned because serum antibodies decline in convalescence. However, functional immunity is mediated by long-lived memory T and B (Bmem) cells. Therefore, we generated fluorescently-labeled tetramers of the spike receptor binding domain (RBD) and nucleocapsid protein (NCP) to determine the longevity and immunophenotype of SARS-CoV-2-specific Bmem cells in COVID-19 patients. A total of 36 blood samples were obtained from 25 COVID-19 patients between 4 and 242 days post-symptom onset including 11 paired samples. While serum IgG to RBD and NCP was identified in all patients, antibody levels began declining at 20 days post-symptom onset. RBD- and NCP-specific Bmem cells predominantly expressed IgM+ or IgG1+ and continued to rise until 150 days. RBD-specific IgG+ Bmem were predominantly CD27+, and numbers significantly correlated with circulating follicular helper T cell numbers. Thus, the SARS-CoV-2 antibody response contracts in convalescence with persistence of RBD- and NCP-specific Bmem cells. Flow cytometric detection of SARS-CoV-2-specific Bmem cells enables detection of long-term immune memory following infection or vaccination for COVID-19.
This study was designed to reveal the relationship between the use and type of eye protection and the occurrence of work-related corneal and conjunctival foreign body injuries.

This is a retrospective cohort study of patients with work-related corneal and/or conjunctival foreign body injuries between 1 August 2017 and 31 July 2018. They were all diagnosed and treated at Jia Ding Hospital affiliated to the Shanghai University of Medicine and Health Sciences in Shanghai, China. All patients received a comprehensive eye examination and a face-to-face interview using a structured questionnaire by ophthalmologists.

A total of 426 consecutive patients were included in the study. The majority of work-related eye injuries occurred in men (94.17%). Summer was the season that had the highest incidence of eye injuries, especially in July and August (38.03%). There were 290 patients (68.08%) that were injured more than once. The ratio of eye protection use to non-protection was 17 at the first time of eye injury. The ratio improved to 13 on subsequent injury. A majority of employers (79.11%) provided eye protection to employees. However, 19.95% of the workers were injured despite wearing a pair of protective spectacles. The causes of work-related eye injury were as follows no eye protections provided (20.89%); unawareness of work safety (30.99%); defect of spectacles (47.18%).

Protection use at work effectively prevents work-related eye injuries. Both employers and employees require improved awareness of workplace hazards and personal protection. Eye protection should be selected appropriately according to the work environment.

The Stopping Elderly Accidents, Deaths and Injuries (STEADI) screening algorithm aligns with current fall prevention guidelines and is easy to administer within clinical practice. However, the stratification into low, moderate and high risk categories limits the meaningful interpretation of the fall-related risk factors.

Baseline measures from a modified STEADI were used to predict self-reported falls over 4 years in 3170 respondents who participated in the 2011-2015 National Health and Aging Trends Study. A point method was then applied to find coefficient-based integers and 4-year fall risk estimates from the predictive model. Sensitivity and specificity estimates from the point method and the combined moderate and high fall risk STEADI categories were compared.

There were 886 (27.95%) and 387 (12.21%) respondents who were classified as moderate and high risk, respectively, when applying the stratification method. Falls in the past year (OR 2.16; 95% CI 1.61 to 2.89), multiple falls (OR 2.94; 95% CI 1.89 to 4.55) and a fear of falling (OR 1.77; 95% CI 1.45 to 2.16) were among the significant predictors of 4-year falls in older adults. The point method revealed integers that ranged from 0 (risk 27.21%) to 44 (risk 99.71%) and a score of 10 points had comparable discriminatory capacity to the combined moderate and high STEADI categories.

Coefficient-based integers and their risk estimates can provide an alternative interpretation of a predictive model that may be useful in determining fall risk within a clinical setting, tracking changes longitudinally and defining the effectiveness of an intervention.

Identifying mutation-carrying relatives of patients with hereditary cancer syndromes via cascade testing is an underused first step in primary cancer prevention. A feasibility study of facilitated genetic testing of at-risk relatives of patients with a known pathogenic mutation demonstrated encouraging uptake of cascade testing.

Our primary objective is to compare the proportion of genetic testing of identified first-degree relatives of probands with a confirmed
mutation randomized to a facilitated cascade testing strategy versus standard of care, proband-mediated, information sharing.

We hypothesize that facilitated cascade testing will drive significantly higher uptake of genetic testing than the standard of care.

The FaCT (Facilitated Cascade Testing) trial is a prospective multi-institutional randomized study comparing the efficacy of a multicomponent facilitated cascade testing intervention with the standard of care. Patients with a known
mutation (probands) cared for at participating sites will be randomized.
