Eyes as Windows: Unveiling Neuroinflammation in Multiple Sclerosis via Optic Neuritis and Uhthoff's Phenomenon.

: This study investigated the frequency and timing of optic neuritis (ON) episodes in relation to the onset of multiple sclerosis (MS) and examined the occurrence of Uhthoff's phenomenon and Lhermitte's sign to understand their roles in early diagnosis and disease progression. : A longitudinal study was conducted with 127 MS patients. Clinical data, including ophthalmological examinations for ON, were collected and questionnaires assessed the presence of Uhthoff's phenomenon and Lhermitte's sign.

Risk Factors for Positive Resection Margins in Breast-Conserving Surgery for Breast Cancer-Retrospective Analysis.

The primary objective of this study was to identify preoperative factors that could be associated with positive resection margins. We also tried to analyze the local recurrence and overall survival in patients who received conservative treatment for early-stage breast cancer and correlate these parameters with preoperative factors. A retrospective examination was conducted on the medical records and pathological reports of 143 patients who underwent breast-conserving surgery (BCS) for breast cancer in our department from 2009 to 2017.

Mechanism of PCNA loading by Ctf18-RFC for leading-strand DNA synthesis.

The proliferating cell nuclear antigen (PCNA) clamp encircles DNA to hold DNA polymerases (Pols) to DNA for processivity. The Ctf18-RFC PCNA loader, a replication factor C (RFC) variant, is specific to the leading-strand Pol (Polε). We reveal here the underlying mechanism of Ctf18-RFC specificity to Polε using cryo-electron microscopy and biochemical studies.

Combining Molecular and Traditional Prognostic Factors: A Holistic Approach to Breast Cancer Prognostication.

Breast cancer is a heterogeneous disease with various morphologies and molecular features, and it is the second leading cause of cancer death in women in developed countries. According to the literature, we currently lack both prognostic biomarkers and therapeutic targets. The most important prognostic factors are disease stage and Nottingham grade.
