Multiple ways of reporting organ weights are sources of confusion in literature. This study was designed to determine if there is a linear relationship between body weights and selected organ and tissue weights in groups of rats after different liquid feeding options. A randomized 2 x 2 x 2 factorial, randomized block design was used with 40 postpubescent male rats with two levels of feeding schedules, kilocalorie levels, and fiber contents. In addition to a skeletal muscle, 13 abdominal and thoracic organs or tissues were weighed. Pearson product-moment correlation coefficients and regression analyses were completed to determine the relationship between these weights and the final body weights. Findings support the need to use different approaches in order to accurately report various organ and tissue weights.

Cryptococcal disease is the third most common invasive fungal infection in solid organ transplant recipients and is associated with high-morbidity and -mortality rates. Donor-derived Cryptococcus spp. infection typically manifests within the first month post-procedure and has historically been caused by C.

Background And Aims: It is assumed that trees should adapt their above and belowground organs as they age. However, most studies to date have quantified these trait adjustments in homogeneous forest stands, confounding the effect of stand aging on soil properties and the intrinsic response of trees to aging.
Methods: Here, we examined 11 morphological, architectural, anatomical and mycorrhizal fine root traits of each of the first five orders for 66 Pinus koraiensis individuals of 16 to 285 years old in northeast China, while accounting for soil characteristics (pH and total C, N and P concentrations).
Organ-specific microenvironments drive divergent T cell evolution in acute graft-versus-host disease.

Tissue-specific T cell immune responses play a critical role in maintaining organ health but can also drive immune pathology during both autoimmunity and alloimmunity. The mechanisms controlling intratissue T cell programming remain unclear. Here, we leveraged a nonhuman primate model of acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation to probe the biological underpinnings of tissue-specific alloimmune disease using a comprehensive systems immunology approach including multiparameter flow cytometry, population-based transcriptional profiling, and multiplexed single-cell RNA sequencing and TCR sequencing.

Tissue-specific endothelial cells (ECs) are critical for the homeostasis of pancreatic islets and most other tissues. In vitro recapitulation of islet biology and therapeutic islet transplantation both require adequate vascularization, which remains a challenge. Using human reprogrammed vascular ECs (R-VECs), human islets were functionally vascularized in vitro, demonstrating responsive, dynamic glucose-stimulated insulin secretion and Ca influx.

Heart development involves the complex structural remodelling of a linear heart tube into an asymmetrically looped and ballooned organ. Previous studies have associated regional expansion of extracellular matrix (ECM) space with tissue morphogenesis during development. We have developed morphoHeart, a 3D tissue segmentation and morphometry software with a user-friendly graphical interface (GUI) that delivers the first integrated 3D visualisation and multiparametric analysis of both heart and ECM morphology in live embryos.
