Fiber is essential for rumen health, microbial fermentation, and the energy supply of herbivores. Even though the study of fecal fiber contents (neutral detergent fiber NDF, acid detergent fiber ADF, and acid detergent lignin ADL) using near-infrared reflectance spectroscopy (NIRS) has allowed investigating nutritional ecology of different herbivore species, NIRS calibrations are species-specific and require a large number of samples for predictions. A multispecies calibration would be an advantage since samples from different herbivores could be used to calibrate a model capable of predicting the fecal fiber content of other herbivores.

The regulator of the canonical Wnt pathway, leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5), is expressed in the stem cell compartment of several tissues and overexpressed in different human carcinomas. The isoform of the stem cell marker LGR5, named LGR5Δ5 and first described by our group, is associated with prognosis and metastasis in oral squamous cell carcinoma (OSCC) and soft tissue sarcoma (STS). In a proof-of-principle analysis, the function of LGR5Δ5 was investigated in HEK293T cells, a model cell line of the Wnt pathway, compared to full-length LGR5 (FL) expression.

Background: Ampullary adenocarcinoma (AAC) typically presents at an early stage due to biliary obstruction and therefore might be specifically suitable for minimally invasive pancreatoduodenectomy (MIPD). However, studies assessing MIPD specifically for AAC, including the robotic and laparoscopic approach, are limited. The aim of this study is to compare short- and long-term oncological resection and perioperative outcomes of robotic (RPD), laparoscopic (LPD) and open pancreatoduodenectomy (OPD) performed specifically for AAC.

Dormancy: Metabolite pools prime the cyanobacterial dormancy-resuscitation switch.

Curr Biol

January 2025

Institute for Microbiology, Martin Luther University Halle-Wittenberg, 06120 Halle (Saale), Germany. Electronic address:

Non-N-fixing cyanobacteria enter a state of dormancy when fixed nitrogen becomes limiting. Resuscitation from this state involves a complex program of events. A new study reveals how the dormancy-resuscitation switch is governed by metabolite-level control of glucose-6-phosphate dehydrogenase activity.

Accurate diagnosis and monitoring of neurodegenerative diseases require reliable biomarkers. Cerebrospinal fluid (CSF) proteins are promising candidates for reflecting brain pathology; however, their diagnostic utility may be compromised by natural variability between individuals, weakening their association with disease. Here, we measured the levels of 69 pre-selected proteins in cerebrospinal fluid using antibody-based suspension bead array technology in a multi-disease cohort of 499 individuals with neurodegenerative disorders including Alzheimer's disease (AD), behavioral variant frontotemporal dementia, primary progressive aphasias, amyotrophic lateral sclerosis (ALS), corticobasal syndrome, primary supranuclear palsy, along with healthy controls.
