The potential of ethylene absorbent (EA) to delay softening of 'Lanfeng' blueberry (Vaccinium spp.) fruit in conjunction with cold storage was evaluated. The fruit quality was evaluated after 60 days of storage at 0 °C again kept at 20 °C, with or without EA. Changes in quality attributes and ethylene biosynthesis and fruit softening indicators were assessed. The results indicated that EA treatment inhibited fruit softening, reduced weight loss and decay, and prevented the loss of total phenolic content. It also decreased the fruit ethylene production by inhibiting 1-aminocyclopropane-1-carboxylic acid oxidase and 1-aminocyclopropane-1- carboxylic acid synthase activities, whilst maintaining firmness by hampering cell wall-degrading enzyme activities, especially after more than 30 days of cold storage. In conclusion, EA treatment can inhibit the softening of harvested blueberry fruit during storage at 0 °C and shelf life after cold storage. After being refrigerated for more than 30 days at 0 °C, the EA has a good effect on blueberries storage.

Fecal microbiota transplantation to prevent acute graft-versus-host disease: pre-planned interim analysis of donor effect.

Gut microbiota disruptions after allogeneic hematopoietic cell transplantation (alloHCT) are associated with increased risk of acute graft-versus-host disease (aGVHD). We designed a randomized, double-blind placebo-controlled trial to test whether healthy-donor fecal microbiota transplantation (FMT) early after alloHCT reduces the incidence of severe aGVHD. Here, we report the results from the single-arm run-in phase which identified the best of 3 stool donors for the randomized phase.

The neuromuscular junction (NMJ) is essential for transmitting signals from motor neurons (MNs) to skeletal muscles (SKMs), and its dysfunction can lead to severe motor disorders. However, our understanding of the NMJ is limited by the absence of accurate human models. Although human induced pluripotent stem cell (iPSC)-derived models have advanced NMJ research, their application is constrained by challenges such as limited differentiation efficiency, lengthy generation times, and cryopreservation difficulties.

Complement functional assays are essential first-tier tests for a gamut of disorders spanning from inborn errors of the immune system which lead to recurrent severe infections, to angioedema attacks, presentation of autoimmune disease, thrombotic microangiopathies and rare kidney disorders. These assays evaluate the activity of the three complement pathways and specific complement components, which helps in differential diagnosis and monitoring disease progression. The rising use of complement inhibitors for treating complement-mediated thrombotic microangiopathies has heightened the demand for personalized treatment plans and laboratory assessment of complement blockage.

The application of spermatogonial stem cells (SSC) will be more effective and feasible following the successful cryopreservation and transfer of SSCs in livestock. Like other cells, SSCs are also sensitive to cryoinjury; hence composition of the cryomedia and freezing protocols need to be optimized. The present study aims to optimising the best freezing rates by minimising the ice crystallization and dehydration effect in order to maximize the post-thaw SSCs survivability and stemness characteristics.

Introduction: Cold static storage (CSS) and normothermic ex-situ preservation are the most widely used donor heart preservation techniques worldwide. The current study compares both CSS and normothermic ex-situ preservation methods in terms of graft performance, morphologic changes, and acute immune response in an experimental model.
Method And Materials: Twenty rats underwent heterotopic abdominal heart transplantation after 2 h of CSS (group 1; n = 10) or normothermic ex-situ perfusion (group 2; n = 10).
