With an increasing aging population, there will be a greater need for cancer evaluation and treatment in older patients. Age alone is not a good predictor of postoperative morbidity, and a multidisciplinary approach is crucial for managing comorbidities. Preoperative optimisation, such as prehabilitation, may in some cases reduce postoperative complications, and minimal invasive techniques should be preferred whenever possible.

Fecal microbiota transplantation in hepatic encephalopathy: a systematic review.

Hepatic encephalopathy (HE) is a reversible neurocognitive dysfunction that ranges in severity from subclinical alterations to coma. Patients with chronic liver disease are predisposed to HE due to metabolic failure and portosystemic shunting of toxins, of which ammonia is believed to be the main toxic chemical. Fecal microbiota transplantation (FMT) may reduce ammonia synthesis by altering the gut microbiota composition to a taxon low in urease, diminish uptake of ammonia by reestablishing the integrity of the intestinal barrier and increase ammonia clearance by improving liver function.

The Dat Project, an open and decentralized research data tool.

Today's scientific data are primarily stored and accessed via centralized Web-based infrastructure. Centralization has advantages but also carries risks such as link rot and content drift, which can hinder scientific progress. It is time to ask whether traditional, centralized Web architecture aligns with scholarly priorities and values, and to collaboratively move towards new approaches that do.

Cognitive Metaphor Theory and the Metaphysics of Immediacy.

One of the core tenets of cognitive metaphor theory is the claim that metaphors ground abstract knowledge in concrete, first-hand experience. In this paper, I argue that this grounding hypothesis contains some problematic conceptual ambiguities and, under many reasonable interpretations, empirical difficulties. I present evidence that there are foundational obstacles to defining a coherent and cognitively valid concept of "metaphor" and "concrete meaning," and some general problems with singling out certain domains of experience as more immediate than others.

Ecosystem properties of semiarid savanna grassland in West Africa and its relationship with environmental variability.

The Dahra field site in Senegal, West Africa, was established in 2002 to monitor ecosystem properties of semiarid savanna grassland and their responses to climatic and environmental change. This article describes the environment and the ecosystem properties of the site using a unique set of in situ data. The studied variables include hydroclimatic variables, species composition, albedo, normalized difference vegetation index (NDVI), hyperspectral characteristics (350-1800 nm), surface reflectance anisotropy, brightness temperature, fraction of absorbed photosynthetic active radiation (FAPAR), biomass, vegetation water content, and land-atmosphere exchanges of carbon (NEE) and energy.

Lu AA21004, a novel multimodal antidepressant, produces regionally selective increases of multiple neurotransmitters--a rat microdialysis and electrophysiology study.

The monoaminergic network, including serotonin (5-HT), norepinephrine (NE), and dopamine (DA) pathways, is highly interconnected and has a well-established role in mood disorders. Preclinical research suggests that 5-HT receptor subtypes, including 5-HT1A, 5-HT1B, 5-HT3, and 5-HT7 receptors as well as the 5-HT transporter (SERT), may have important roles in treating depression. This study evaluated the neuropharmacological profile of Lu AA21004, a novel multimodal antidepressant combining 5-HT3 and 5-HT7 receptor antagonism, 5-HT1B receptor partial agonism, 5-HT1A receptor agonism, and SERT inhibition in recombinant cell lines.
