AI Article Synopsis
- A study investigated three introgression lines (ILs) of tomato chromosome 7, incorporating DNA from Lycopersicon pennellii, through AFLP screening using specific primer combinations.
- Numerous genetic markers were discovered that corresponded to distinct regions on chromosome 7, with many being consistent with previously established tomato reference maps.
- Notably, these ILs contained an unexplored section of chromosome 10 with a cluster of six AFLP markers, which had not been identified via traditional RFLP methods, raising questions about the significance of these findings.
Article Abstract
A set of three tomato chromosome 7 introgression lines (ILs) containing overlapping segments of Lycopersicon pennellii DNA was screened with a set of 10 EcoRI-MseI and 10 PstI-MseI AFLP primer combinations. A large number of markers were identified that mapped to one of the four regions of chromosome 7 defined by the set of three ILs. Because many of the identified markers have known map positions in three tomato reference maps, their location on the tomato genome could be verified. It was demonstrated that the three chromosome 7 ILs carried a chromosome 10 region harbouring a cluster of six AFLP markers that had not been detected before using RFLPs. The causes and implications of this observation are discussed.

Spinal cord injury (SCI) is a significant cause of lifelong disability, with no available disease-modifying treatments to promote neuroprotection and axon regeneration after injury. Photobiomodulation (PBM) is a promising therapy which has proven effective at restoring lost function after SCI in pre-clinical models. However, the precise mechanism of action is yet to be determined.

Direct printed aligners (DPAs) offer benefits like the ability to vary layer thickness within a single DPA and to 3D print custom-made removable orthodontic appliances. The biocompatibility of appliances made from Tera Harz TA-28 (Graphy Inc., Seoul, South Korea) depends on strict adherence to a standardized production and post-production protocol, including UV curing.

Osteoporosis is the most common bone metabolic unbalance, leading to fragility fractures, which are known to be associated with structural changes in the bone. Cortical bone accounts for 80 % of the skeleton mass and undergoes remodeling throughout life, leading to changes in its thickness and microstructure. Although many studies quantified the different cortical bone structures using CT techniques (3D), they are often realised on a small number of samples.

Introduction: More extensive and cohesive studies on quadriceps tendon rupture (QTR) repair surgery are required to guide effective treatment strategies. Therefore, in this study, we aimed to identify predictors of subjective functional recovery following QTR repair surgery.
Materials And Methods: This multicentre retrospective cohort study enrolled 191 adults (age ≥ 18 years) who underwent surgical unilateral QTR repair (2010-2022) and had ≥ 1-year postoperative follow-up at three trauma centres in Germany.

Post-acute sequelae of COVID-19 (PASC) are a diverse set of symptoms and syndromes driven by dysfunction of multiple organ systems that can persist for years and negatively impact the quality of life for millions of individuals. We currently lack specific therapeutics for patients with PASC, due in part to an incomplete understanding of its pathogenesis, especially for non-pulmonary sequelae. Here, we discuss three animal models that have been utilized to investigate PASC: non-human primates (NHPs), hamsters, and mice.
