Impact of extended endocrine therapy for patients with risk factors for late recurrence in estrogen receptor-positive, human epidermal growth factor receptor 2-negative breast cancer after 5 years of endocrine therapy.

Purpose: Extended endocrine therapy shows promise for reducing the recurrence of estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer. However, its benefits in patients with high-risk factors for late recurrence remain unclear, particularly in premenopausal patients. In this study, we aimed to explore the impact of extended endocrine therapy in patients with risk factors for late recurrence of postmenopausal and premenopausal ER-positive, HER2-negative breast cancer.

Development of an ultrasound-guided radiofrequency ablation technique in the equine cadaveric distal limb: histological findings and potential for treating chronic lameness.

Introduction: Radiofrequency (RF) relieves chronic pain in humans, but it is unexplored in horses affected by chronic lameness. This study aims to describe the technique and the histological effects of ultrasound (US)-guided radiofrequency ablation (RFA) of palmar digital nerves (PDNs) in horse's fetlock and pastern, .

Methods: After assessing the US anatomy of lateral and medial PDNs in fetlock and pastern ( = 10 horses; 20 forelimbs), US-guided RFA was performed on these sites in cadaveric forelimbs ( = 10) applying four different settings with increasing invasiveness ( = 40 total treatments): 60°C, 6 min (GROUP LOW); 70°C, 4 min (GROUP MEDIUM); 90°C, 2 min (GROUP HIGH); 80°C, 8 min (GROUP VERY HIGH).

Positive effect of a diggable substrate on the behaviour of a captive naked mole rat colony.

Naked mole rats (Heterocephalus galber) are eusocial mammals from East Africa. Their extraordinary social organisation is accompanied by remarkable adaptations to an underground lifestyle, extreme longevity and resistance to many diseases, making naked mole rats a highly relevant model for biological research. However, their living conditions in controlled environments do not allow them to express fundamental behaviours: digging galleries and exploring.

High levels of plasma neurofilament light chain correlated with brainstem and peripheral nerve damage.

Background And Objectives: Blood neurofilament light chain (NfL) is a minimally invasive, but highly sensitive biomarker of neurological diseases. However, diseases and neurological damage associated with increased NfL remain unclear. Therefore, the present study investigated factors associated with increased plasma NfL levels in various neurological diseases, focal lesions and pathological processes.
