Environmental DNA metabarcoding can be used to affordably, efficiently, and accurately census biodiversity factors in marine systems. Although taxonomic assignments are still limited by species coverage in genetic reference databases, use of MOTUs highlights the potential of eDNA metabarcoding once reference databases have expanded.

Rabies postexposure prophylaxis (PEP), including both rabies immunoglobulin (RIG) and vaccination, is administered to 55,000 patients annually in the United States. With a nearly 100% case fatality rate, the optimal administration of rabies PEP cannot be understated. Updated rabies PEP guidelines issued by the World Health Organization (WHO) in 2018 recognized that local wound infiltration of RIG is the primary mechanism of protection, and the WHO now recommends only infiltration of wounds without distal intramuscular injection. We highlight potential points of failure involving wound infiltration of RIG, small-volume doses, and large-volume doses that may lead to suboptimal care and discuss implications of recent shifts toward evidence-based guidelines using wound type and RIG volumes.Treatment de-escalation is sought in the management of precursor lesions of early stage breast cancer, driving the appeal of adjuvant modalities to lumpectomy that reduce toxicity and minimally detract from patient quality of life. We investigate photodynamic therapy (PDT), with the photosensitizing prodrug, 5-aminolevulinic acid (ALA), as adjuvant therapy to complete resection of murine mammary tumor (propagated from TUBO cells). ALA was delivered either systemically (oral, 250 mg kg-1 ) at 5 h before 632 nm illumination or topically (20% solution) to the resection site at 10 min before light delivery to 135 J cm-2 . Treatment with either oral-ALA-PDT (oALA-PDT) or topical-ALA-PDT (tALA-PDT) to the mammary fat pad after TUBO complete resection (CR) produced long-term tumor control with 90-day complete response rates of 21% and 32%, respectively, compared to control rates of 0-5% in mice receiving only CR. Thus, CR/tALA-PDT was equipotent to CR/oALA-PDT despite ~10-fold lower levels of ALA-induced protoporphyrin XI as photosensitizer after topical versus oral-ALA administration. CR/oALA-PDT produced more vascular damage, greater proportion of tissue-resident neutrophils and stronger inflammation when compared to CR/tALA-PDT. Collectively, these data provide rationale for ongoing investigation of ALA-PDT as adjuvant therapy after lumpectomy for increased probability of local control in the treatment of breast cancer.Accurate and comprehensive testing is crucial for practitioners to portray the pandemic. Without testing there is no data; yet, the exact number of infected people cannot be determined due to the lack of comprehensive testing. The number of seropositive for SARS-CoV-2 infection is obviously relative to the extent of testing. However, the true number of infections might be still far higher than the reported values. To compare the countries based on the number of seropositive for SARS-CoV-2 infection is misleading, as there may not be enough tests being carried out to properly monitor the outbreak. In this paper, we closely look through the COVID-19 testing results. Herein, we try to draw conclusions based on the reported data first, the presence of a possible relationship between COVID-19 transition and patients’ age will be assessed. Then, the COVID-19 case fatality rate (CFR) is compared with the age-demographic data for different countries. Based on the results, a method for estimating a lower bound (minimum) for the number of actual positive cases will be developed and validated. Results of this study have shown that CFR is a metric reflecting the spread of the virus, but is a factor of the extent of testing and does not necessarily show the real size of the outbreak. Moreover, no large difference in susceptibility by age has been found. The results suggest the similarity between the age distribution of COVID-19 and the population age-demographic is improving over the course of the pandemic. In addition, countries with lower CFRs have a more similar COVID-19 age distribution, which is a result of more comprehensive testing. Finally, a method for estimation of the real number of infected people based on the age distributions, reported CFRs, and the extent of testing will be developed and validated.How can we imagine someone’s experience of illness-even extreme cases, like, for example, psychosis-to the extent that we begin to empathize as if the experience were nearly our own? Based on 5 years of archival research and anthropological fieldwork, I investigate how different forms of understanding and empathy have emerged through the work of people living with dementia (dementia tōjishas), some of who have advocated for the cause in Japan. I show how those with dementia used to be regarded as incommensurable beings, who were sometimes romanticized as having a transcendental power, and how those who care for them have changed their perspectives as they began to see dementia tōjisha as possible versions of their future selves. I also describe the rise of the tōjisha movement and the ways in which it has raised questions about the limits of empathy and instead asserted rights as a basis of understanding. In doing so, dementia tōjisha may be questioning the very foundation of Japanese society, highly invested as it is in the virtue of empathy for maintaining social relations.

Positron emission tomography (PET) imaging with various tracers is increasingly used in Alzheimer’s disease (AD) studies. However, access to PET scans using new or less-available tracers with sophisticated synthesis and short half-life isotopes may be very limited. Therefore, it is of great significance and interest in AD research to assess the feasibility of generating synthetic PET images of less-available tracers from the PET image of another common tracer, in particular

F-FDG.

We implemented advanced deep learning methods using the U-Net model to predict

C-UCB-J PET images of synaptic vesicle protein 2A (SV2A), a surrogate of synaptic density, from

F-FDG PET data. Dynamic

F-FDG and

C-UCB-J scans were performed in 21 participants with normal cognition (CN) and 33 participants with Alzheimer’s disease (AD). Cerebellum was used as the reference region for both tracers. For

C-UCB-J image prediction, four network models were trained and tested, which included 1)

F-FDG SUV ratio (SUVR) ging information is needed.

The study aimed to assess job satisfaction and stress among dental faculty members. It was also planned to explore their experiences and probable solutions through a mixed-method approach.

Sequential explanatory mixed-method approach was employed. In the quantitative phase, a cross-sectional web-based questionnaire survey was conducted among dental faculty members in Tamil Nadu, India using the „Google Forms application” link. Based on Dentist Satisfaction Survey, a questionnaire was framed, validated, and used. It included 25 items under four domains (PICS) personal, institutional, cofaculty, and students. Mann-Whitney test was used to compare the differences between two independent groups. Kruskal-Wallis test and Friedman test were used for multiple group comparisons. In the qualitative phase one-on-one, semistructured telephone interviews were conducted among 27 dental faculties from various sectors.

A total of 408 participants took part in the quantitative survey. The students-related domain was found to be the most dissatisfied or stressful domain (2.05±0.3) among dental faculties followed by the institutional domain (1.92±0.4) and cofaculty-related domain (1.81±0.6). Based on qualitative interviews, four themes were derived namely (1) academia as a profession, (2) potential stressors, (3) sequelae of stress, and (4) stress-free job.

The present study provided deep insight into the stress among dental faculty members and emphasized the need for student-faculty mentor programs. It also stressed the importance of organized monetary structures or pay scales in private dental institutions in India.

However, its importance in muscle and physical exercise is currently unknown. We observed that following acute high-intensity exercise („Gran Sasso d’Italia” vertical run), LCN2 serum levels were increased. The Wnt pathway antagonist, DKK1, was also increased after the run, positively correlating with LCN2, and the same was found for the cytokine Interleukin 6. We, therefore, investigated the involvement of LCN2 in muscle physiology employing an Lcn2 global knockout (Lcn2-/- ) mouse model. Lcn2-/- mice presented with smaller muscle fibres but normal muscle performance (grip strength metre) and muscle weight. At variance with wild type (WT) mice, the inflammatory cytokine Interleukin 6 was undetectable in Lcn2-/- mice at all ages. Intriguingly, Lcn2-/- mice did not lose gastrocnemius and quadriceps muscle mass and muscle performance following hindlimb suspension, while at variance with WT, they lose soleus muscle mass. In vitro, LCN2 treatment reduced the myogenic differentiation of C2C12 and primary mouse myoblasts and influenced their gene expression. Treating myoblasts with LCN2 reduced myogenesis, suggesting that LCN2 may negatively affect muscle physiology when upregulated following high-intensity exercise.

To reduce the exposed area by the multileaf collimator between lesions for single-isocenter dynamic conformal arc (DCA) therapy for stereotactic radiosurgery treatment of multiple brain metastases by optimizing the collimator angle orientation. In particular, this is achieved by the avoidance of collimator angles where multiple lesions are exposed by the same leaf pairs.

An algorithm that estimates the quality of an arc by considering the target projections onto the plane perpendicular to the central axis of the arc beam. A penalty proportional to the exposure of healthy tissue between metastases is assigned to each control point and each feasible collimator angle from a discretized set of angles. The algorithm can generate two outputs the fixed optimal collimator angle over all the control points, or the optimal collimator angle trajectory through all the control points considering the rotation speed of the collimator. The first output is based on explicit enumeration of all collimator angles, and the sejectories are capable of limiting the island blocking problem more than optimal fixed trajectories by exploiting the extra degree of freedom of rotating the multileaf collimator. The algorithm can also lead to time saving during the treatment planning process.

Collimator angle optimization has the potential to reduce the magnitude of the exposed area between lesions in an efficient way for non-isocentric treatments where multiple lesions are treated simultaneously. Dynamic trajectories are capable of limiting the island blocking problem more than optimal fixed trajectories by exploiting the extra degree of freedom of rotating the multileaf collimator. The algorithm can also lead to time saving during the treatment planning process.
