Low-grade endometrial stromal sarcoma (LGESS) is a rare disease, accounting for less than 1% of all uterine malignancies. Standard treatment is total hysterectomy and bilateral tubal oophorectomy, although fertility preservation may be desirable because of the young age of onset. We document a case of fertility preservation in a 27-year-old nulligravida diagnosed with LGESS, which not only enabled the successful birth of two live infants but also underscores the efficacy of a multidisciplinary approach to patient treatment through the Hyogo Oncofertility Network (HOF-net).

Article Synopsis
  • Researchers fused inactive Cas13 proteins with a modified human ADAR2 deaminase to create a new method for precise RNA editing without causing permanent changes in the genome.
  • The new platform, called xPERT, was engineered to improve the balance between effective on-target editing and reduced off-target activity, addressing a major concern in existing RNA-editing technologies.
  • Compared to previous systems (REPAIRv1 and REPAIRv2), xPERT demonstrates strong on-target editing while minimizing unintended alterations, making it a potentially safer option for customizing RNA and protein functions.

This study presents a dataset of audio-visual soundscape recordings at 62 different locations in Singapore, initially made as full-length recordings over spans of 9-38 min. For consistency and reduction in listener fatigue in future subjective studies, one-minute excerpts were cropped from the full-length recordings. An automated method using pre-trained models for Pleasantness and Eventfulness (according to ISO 12913) in a modified partitioning around medoids algorithm was employed to generate the set of excerpts by balancing the need to encompass the perceptual space with uniformity in distribution.

Article Synopsis
  • 5-Fluorouracil (5-FU) causes pigmentation in patients, negatively affecting their quality of life, but the underlying mechanism is not fully understood.
  • During a study using male HRM-2 hairless mice, researchers observed increased melanin accumulation and blood vessel activity in the skin after 8 weeks of 5-FU treatment.
  • Unlike other chemotherapy drugs like cytarabine and irinotecan, 5-FU specifically leads to hyperpigmentation, suggesting a link between 5-FU, tyrosinase activity, and blood vessel enhancement.

Article Synopsis
  • A bronchogenic cyst is a type of abnormal growth that happens from the trachea and bronchi, which are the tubes that help you breathe.
  • It's not common for these cysts to be found in the neck area, but a girl had a painless bump there.
  • Doctors thought it was a different kind of cyst at first, but later checks showed it was actually a bronchogenic cyst, so doctors need to remember this when looking at neck lumps in kids.

The quantification and characterization of aggregated α-synuclein in clinical samples offer immense potential toward diagnosing, treating, and better understanding neurodegenerative synucleinopathies. Here, we developed digital seed amplification assays to detect single α-synuclein aggregates by partitioning the reaction into microcompartments. Using pre-formed α-synuclein fibrils as reaction seeds, we measured aggregate concentrations as low as 4 pg/mL.

Microalgae's exceptional photosynthetic prowess, CO adaptation, and high-value bioproduct accumulation make them prime candidates for microorganism-based biorefineries. However, most microalgae research emphasizes downstream processes and applications rather than fundamental biomass and biochemical balances and kinetic under the influence of greenhouse gases such as CO. Therefore, three distinctly different microalgae species were cultivated under 0% to 20% CO treatments to examine their biochemical responses, biomass production and metabolite accumulations.

Article Synopsis
  • Anticancer drugs, including 5-fluorouracil (5-FU), often cause skin pigmentation as a side effect, negatively impacting patients' quality of life (QOL).
  • This study aimed to uncover the mechanism behind 5-FU-induced skin pigmentation using specific mice models that were treated with the drug for 8 weeks.
  • The findings revealed that the pigmentation process involves an oxidative stress/NF-κB/ACTH/cAMP/tyrosinase pathway, which can be inhibited to reduce pigmentation in 5-FU-treated mice.
