Root Development of Tomato Plants Infected by the Cacao Pathogen Moniliophthora perniciosa Is Affected by Limited Sugar Availability.

Moniliophthora perniciosa is the causal agent of the witches' broom disease of cacao (Theobroma cacao), and it can infect the tomato (Solanum lycopersicum) 'Micro-Tom' (MT) cultivar. Typical symptoms of infection are stem swelling and axillary shoot outgrowth, whereas reduction in root biomass is another side effect. Using infected MT, we investigated whether impaired root growth derives from hormonal imbalance or sink competition.

Rectal synovial sarcoma case report - An unexpected cause of acute lower gastrointestinal bleeding.

Introduction And Importance: Acute lower gastrointestinal bleeding is one of the most common causes of hospital admission. However, massive bleeding is uncommon and is mainly due to hemorrhoidal bleeding in elderly patients receiving anticoagulant therapy. We present a rare case of a massive rectal haemorrhage with an uncommon cause.

Level of Necrosis in Feline Mammary Tumors: How to Quantify, Why and for What Purpose?

Necrosis is a common finding in human and animal neoplasms. The percentage of tumor necrosis is included in tumor grading schemes in veterinary oncology; however, evaluation methods are often overlooked. Different studies have assessed the prognostic value of tumor necrosis in feline mammary tumors with contradictory results, which could be related to methodologic variability.

Cross-Interactions of Aβ Peptides Implicated in Alzheimer's Disease Shape Amyloid Oligomer Structures and Aggregation.

A defining hallmark of Alzheimer's disease (AD) is the synaptic aggregation of the amyloid β (Aβ) peptide. , Aβ production results in a diverse mixture of variants, of which Aβ40, Aβ42, and Aβ43 are profusely present in the AD brain, and their relative abundance is recognized to play a role in disease onset and progression. Nonetheless, the occurrence of Aβ40, Aβ42, and Aβ43 hetero-oligomerization and the subsequent effects on Aβ aggregation remain elusive and were investigated here.

How do rest-pause and sarcoplasma stimulating training models affect metabolic and psychoaffective responses in bodybuilding athletes compared to traditional training?

Introduction: Strength training (ST) is a strategy to enhance quality of life through increased strength, muscle hypertrophy, and functional capacity. Training systems are associated with manipulation of volume and intensity, generating different stimuli, such as Rest-Pause (RP) and Sarcoplasmic Stimulating Training (SST). These systems induce greater mechanical and physiological stress, leading to increased strength and muscle hypertrophy.
