This article recounts my graduate research at Yale University (1954-1958) on unbalanced growth in during thymine deprivation or following ultraviolet (UV) irradiation, with early evidence for the repair of UV-induced DNA damage. Follow-up studies in Copenhagen (1958-1960) in the laboratory of Ole Maaløe led to my discovery that the DNA replication cycle can be synchronized by inhibiting protein and RNA syntheses and that an RNA synthesis step is essential for initiation of the cycle, but not for its completion. This work set the stage for my subsequent research at Stanford University, where the repair replication of damaged DNA was documented, to provide compelling evidence for an excision-repair pathway. That universal pathway validates the requirement for the redundant information in the complementary strands of duplex DNA to ensure genomic stability.

A patient with borderline left ventricle successfully underwent biventricular repair following a staged surgical approach to promote left ventricular growth. Despite initial concerns about left ventricle size, apex formation and adequate size of atrioventricular valve indicated potential for future growth. The patient demonstrated significant left ventricular growth, resulting in stable biventricular circulation and a favourable outcome over a three-year postoperative follow-up period.

Pampus argenteus, a species distributed throughout the Indo-West Pacific, plays a significant role in the yield of aquaculture species. However, cultured P. argenteus has always been characterised by unbalanced growth synchronisation among individuals, slow growth rate, and lack of excellent germplasm resources.

To address the challenges of unbalanced class labels with varying maturity levels of tomato fruits and low recognition accuracy for both fruits and stems in intelligent harvesting, we propose the YOLOX-SE-GIoU model for identifying tomato fruit maturity and stems. The SE focus module was incorporated into YOLOX to improve the identification accuracy, addressing the imbalance in the number of tomato fruits and stems. Additionally, we optimized the loss function to GIoU loss to minimize discrepancies across different scales of fruits and stems.

A 56-day culture experiment was conducted to assess the effects of lysophospholipid added to a low-fishmeal diet on growth performance, hepatopancreas health, and intestinal microbiome of . Three experimental diets were set up in this study: normal fishmeal positive control diet (20% fishmeal, P), low fishmeal negative control diet (12% fishmeal, N), and low fishmeal + lysophospholipid diet (12% fishmeal with 0.1% lysophospholipid, L).
