Role of Tumor-Infiltrating Lymphocytes and the Tumor Microenvironment in the Survival of Malignant Parotid Gland Tumors: A Two-Centre Retrospective Analysis of 107 Patients.

This study aims to retrospectively investigate the prognostic significance of the tumor microenvironment, with a focus on TILs (tumor-infiltrating lymphocytes), in relation to survival in a large cohort of patients with parotid gland cancer, and it uses the method proposed by the International TILs Working Group in breast cancer. We included a cohort of consecutive patients with biopsy-proven parotid cancer who underwent surgery between January 2010 and September 2023. A retrospective review of medical records, including surgical, pathological and follow-up reports, was performed.

Event segmentation protects emotional memories from competing experiences encoded close in time.

Fear memories are characterized by their permanence and a fierce resistance to unlearning by new experiences. We considered whether this durability involves a process of memory segmentation that separates competing experiences. To address this question, we used an emotional learning task designed to measure recognition memory for category exemplars encoded during competing experiences of fear-conditioning and extinction.

Fetal macrosomia and management of delivery.

During the period 1988-1966, 737 pregnancies, in which the infant birth weight was > or = 4000 grams were studied. During the same period there were 11,631 newborns, and 6.3% of them were infants with a birth weight > or = 4000 grams.

[Fetal macrosomia and mode of delivery].

During the period 1988-1993 the route of delivery in 482 infants with birth weight > or = 4000 grams was studied. Normal vaginal delivery occurred in 396 (82.1%) cases, vacuum extractor in 8 (1.

Characterization and cloning of two Rhizobium leguminosarum genes coding for glutamine synthetase activities.

We have demonstrated that Rhizobium leguminosarum strain LPR1105 contains a heat stable and a heat labile glutamine synthetase (EC 6.3.1.
