Ovarian cancer, colloquially termed the "king of gynecological cancers," presents significant diagnostic and therapeutic challenges due to its covert nature. It ranks as the deadliest gynecologic malignancy with a disheartening 5-year survival rate below 40%. Standard therapeutic protocols for newly diagnosed patients encompass cytoreductive surgery followed by neoadjuvant or adjuvant platinum-based chemotherapy.

With the development of artificial intelligence technology and the growing demand for minimally invasive surgery, the intelligentization of minimally invasive surgery has become a current research hotspot. Surgical instrument segmentation is a highly promising technology that can enhance the performance of minimally invasive endoscopic imaging systems, surgical video analysis systems, and other related systems. This article summarizes the semantic and instance segmentation methods of minimally invasive surgical instruments based on deep learning, deeply analyzes the supervision methods of training algorithms, network structure improvements, and attention mechanisms, and then discusses the methods based on the Segment Anything Model.

This study aimed to explore the clinical significance and potential mechanisms of long non-coding RNA CRNDE in the development of HS. This study encompassed 71 HS patients, and the expression levels of lncRNA CRNDE were assessed via RT-qPCR.

Four molecular subtypes with different clinical outcomes have been identified: POLE mutation, mismatch repair deficient, p53 abnormal, and no specific molecular profile. However, determining these subtypes typically relies on expensive gene sequencing.

Polysulfides commonly occur in anaerobic, microbial active environments, where they play key roles in sulfur cycling and redox transformations. Anaerobic survival of microorganisms requires the formation of protein disulfide bond (DSB). The relationship between polysulfides and anaerobic DSB formation has not been studied so far.

This study aimed to evaluate the predictive performance of homologous recombination deficiency status at genomic and functional perspective on the efficacy of platinum-based chemotherapy in ovarian cancer.
Methods: Between 2016 and 2019, 134 patients with high-grade ovarian cancer were retrospectively analyzed.
In recent years, circRNAs have garnered increasing attention for their role in cervical cancer. However, the functions of many newly identified circRNAs remain unclear and require further exploration. In this study, we investigated the expression and oncogenic potential of the novel circRNA circSTX6 in cervical cancer.

However, the pathophysiological mechanisms underlying USN remain largely unknown. This study aims to investigate the relationship between the fractional amplitude of low-frequency fluctuations (fALFF) in the right hemisphere of patients with post-stroke USN and the severity of neglect using resting-state functional near-infrared spectroscopy (fNIRS) technology.

There are limited existing studies on the potential health benefits of MNG, and currently there is no evidence to suggest that MNG has any impact on skin-aging. Tumor necrosis factor-alpha (TNF-α) plays a significant role in skin aging by promoting chronic inflammation, damaging skin cells, and impairing the skin's natural repair mechanisms.

Recent guidelines have clarified how homologous recombination deficiency (HRD) may influence treatment decision-making in this setting. As a result, numerous companion diagnostic assays (CDx) have been developed to identify HRD.

Methods: Patients with partially platinum-sensitive, platinum-resistant, or platinum-refractory ovarian cancer were recruited in this prospective, open-label, single-arm, multicenter study. Eligible patients were given 4-6 cycles of PLD (40 mg/m2 on day 1, every 4 weeks).
Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder and metabolic abnormality disease that mainly affects women of reproductive age. LINC00173, a novel long noncoding RNA (lncRNA), has emerged as an important factor in the development of PCOS. However, the role of LINC00173 in PCOS development and its specific upstream and downstream mechanisms remain to be further clarified.
View Article and Find Full Text PDFBreak-induced replication (BIR) is mutagenic, and thus its use requires tight regulation, yet the underlying mechanisms remain elusive. Here we uncover an important role of 53BP1 in suppressing BIR after end resection at double strand breaks (DSBs), distinct from its end protection activity, providing insight into the mechanisms governing BIR regulation and DSB repair pathway selection. We demonstrate that loss of 53BP1 induces BIR-like hyperrecombination, in a manner dependent on Polα-primase-mediated end fill-in DNA synthesis on single-stranded DNA (ssDNA) overhangs at DSBs, leading to PCNA ubiquitination and PIF1 recruitment to activate BIR.
