Advances in the understanding and therapeutic manipulation of cancer immune responsiveness: a Society for Immunotherapy of Cancer (SITC) review.

Cancer immunotherapy-including immune checkpoint inhibition (ICI) and adoptive cell therapy (ACT)-has become a standard, potentially curative treatment for a subset of advanced solid and liquid tumors. However, most patients with cancer do not benefit from the rapidly evolving improvements in the understanding of principal mechanisms determining cancer immune responsiveness (CIR); including patient-specific genetically determined and acquired factors, as well as intrinsic cancer cell biology. Though CIR is multifactorial, fundamental concepts are emerging that should be considered for the design of novel therapeutic strategies and related clinical studies.

International Symposium on Ruminant Physiology: Maternal nutrient supply: Impacts on physiological and whole animal outcomes in offspring.

Demands for animal products are projected to increase in the future, and animal production is key to agricultural sustainability and food security; consequently, enhancing ruminant livestock production efficiencies in sustainable ways is a major goal for the livestock industry. Developmental programming is the concept that various stressors, including compromised maternal nutrition during critical developmental windows will result in both short- and long-term changes in the offspring. Ruminant models of developmental programming indicate that compromised maternal nutrition, including global under and over-nutrition, macronutrients, and specific micronutrients, including amino acids (Met and Arg), vitamins (folate, B, and choline), and minerals (sulfur, cobalt, and selenium) can alter offspring outcomes.

Parents Plus: A Parent-Implemented Intervention for Preschool Children With Developmental Language Disorders.

Purpose: Parent engagement is a critical component of optimizing services for young children with disabilities, including those with language disorders. Without training, however, many parents may lack the knowledge and skills to effectively facilitate their children's language development during the essential early childhood years. The Parents Plus intervention was designed to support parents, through online training and coaching, in using focused stimulation, an evidence-based strategy for fostering early language development.

A One Health approach to pastoral (im)mobility, health, and disease: A qualitative participatory study in Plateau State, Nigeria.

In Plateau State, pastoralism has historically been a cost effective and resilient economic system well-suited to the ecological context. However, changes in land use and conflict have increasingly changed patterns of mobility. Pastoralist movement is now often associated with zoonotic disease transmission, environmental degradation and conflict, increasingly resulting in forced sedentarisation.

Emergency infection prevention and control training in fragile, conflict-affected or vulnerable settings: a scoping review.

Background: It is uncertain what could be the best training methods for infection prevention and control when an infectious disease threat is active or imminent in especially vulnerable or resource-scarce settings.

Methods: A scoping review was undertaken to find and summarise relevant information about training modalities, replicability and effectiveness of IPC training programmes for clinical staff as reported in multiple study designs. Eligible settings were conflict-affected or in countries classified as low-income or lower-middle income (World Bank 2022 classifications).

Dynamics of Endothelial Cell Diversity and Plasticity in Health and Disease.

Endothelial cells (ECs) are vital structural units of the cardiovascular system possessing two principal distinctive properties: heterogeneity and plasticity. Endothelial heterogeneity is defined by differences in tissue-specific endothelial phenotypes and their high predisposition to modification along the length of the vascular bed. This aspect of heterogeneity is closely associated with plasticity, the ability of ECs to adapt to environmental cues through the mobilization of genetic, molecular, and structural alterations.

Identifying the immunoglobulin G transporter in equine tissues: A look at the neonatal Fc receptor.

The neonatal Fc receptor (FcRn) is the receptor responsible for bidirectional transport of immunoglobulin G (IgG) across cells, maintenance of IgG levels in serum, and assisting with antigen presentation. Unfortunately, little is known about FcRn in horses. Therefore, the objective of this study was to provide fundamental information regarding the location of FcRn in equine tissues.

Unifying considerations and evidence of macrophage activation mosaicism through human CSF1R and M1/M2 genes.

Addressing the mononuclear phagocyte system (MPS) and macrophage M1/M2 activation is important in diagnosing hematological disorders and inflammatory pathologies and designing therapeutic tools. CSF1R is a reliable marker to identify all circulating MPS cells and tissue macrophages in humans using a single surface protein. CSF1R permits the quantification and isolation of monocyte and dendritic cell (DC) subsets in conjunction with CD14, CD16, and CD1c and is stable across the lifespan and sexes in the absence of overt pathology.

Thermoluminescent dosimeters (TLD-100) for absorbed dose measurements in alpha-emitting radionuclides.

Early works that used thermoluminescent dosimeters (TLDs) to measure absorbed dose from alpha particles reported relatively high variation (10%) between TLDs, which is undesirable for modern dosimetry applications. This work outlines a method to increase precision for absorbed dose measured using TLDs with alpha-emitting radionuclides by applying an alpha-specific chip factor (CF) that individually characterizes the TLD sensitivity to alpha particles. Variation between TLDs was reduced from 21.

A marine cryptochrome with an inverse photo-oligomerization mechanism.

Cryptochromes (CRYs) are a structurally conserved but functionally diverse family of proteins that can confer unique sensory properties to organisms. In the marine bristle worm Platynereis dumerilii, its light receptive cryptochrome L-CRY (PdLCry) allows the animal to discriminate between sunlight and moonlight, an important requirement for synchronizing its lunar cycle-dependent mass spawning. Using cryo-electron microscopy, we show that in the dark, PdLCry adopts a dimer arrangement observed neither in plant nor insect CRYs.

Systematic discovery of neoepitope-HLA pairs for neoantigens shared among patients and tumor types.

The broad application of precision cancer immunotherapies is limited by the number of validated neoepitopes that are common among patients or tumor types. To expand the known repertoire of shared neoantigen-human leukocyte antigen (HLA) complexes, we developed a high-throughput platform that coupled an in vitro peptide-HLA binding assay with engineered cellular models expressing individual HLA alleles in combination with a concatenated transgene harboring 47 common cancer neoantigens. From more than 24,000 possible neoepitope-HLA combinations, biochemical and computational assessment yielded 844 unique candidates, of which 86 were verified after immunoprecipitation mass spectrometry analyses of engineered, monoallelic cell lines.

Pathogenesis and Diagnosis of Proximal Hamstring Tendinopathies.

The proximal hamstring complex is a highly vulnerable area that is especially prone to injury. Proximal hamstring tendinopathies (PHTs) remain challenging in diagnosis, treatment, rehabilitation, and prevention due to a large variety of different injuries, slow healing response, persistent symptoms, and functional impairments. PHTs are often misdiagnosed or underdiagnosed, leading to delayed treatment and therapy failure.

Building on cultural and linguistic strengths and recognizing life challenges - a commentary on Paradis' "Sources of individual differences in the dual language development of heritage bilinguals".

Children growing up bilingually are often treated as a monolithic group; however, heritage language (HL) bilinguals constitute an extremely heterogenous group that vary due to a wide variety of factors. In her keynote, Paradis provides a thought-provoking analysis of the research literature and identifies key internal and external factors that lead to individual differences. Specifically, she identifies age of second language (L2) acquisition, cognitive abilities, and social-emotional wellbeing as important internal factors.

Creation of waterproof, TLD probes for dose measurements to validate image-based radiopharmaceutical therapy dosimetry workflow.

Voxel-level dosimetry based on nuclear medicine images offers patient-specific personalization of radiopharmaceutical therapy (RPT) treatments. Clinical evidence is emerging demonstrating improvements in treatment precision in patients when voxel-level dosimetry is used compared to MIRD. Voxel-level dosimetry requires absolute quantification of activity concentrations in the patient, but images from SPECT/CT scanners are not quantitative and require calibration using nuclear medicine phantoms.
