The InP(100) Surface Phase Diagram: From the Gas Phase to the Electrochemical Environment.

The versatile optoelectronic properties of the material class of III-V semiconductors enable the highest performance in photovoltaic and photoelectrochemical solar cells. While a high level of control and understanding with respect to different surface reconstructions of these compounds in gas-phase ambient has been reached, the situation in an electrochemical environment still poses challenges. Here, we therefore have undertaken a computational study of the InP(100) surface in the presence of hydrogen and chlorine, mimicking the contact with a hydrochloric acid-containing electrolyte, aiming at an understanding of ion adsorption and dominant surface reconstructions with respect to applied potential and electrolyte concentration.

Challenges in estimating species' age from phylogenetic trees.

Aim: Species age, the elapsed time since origination, can give insight into how species longevity might influence eco-evolutionary dynamics, which has been hypothesized to influence extinction risk. Traditionally, species' ages have been estimated from fossil records. However, numerous studies have recently used the branch lengths of time-calibrated phylogenies as estimates of the ages of extant species.

Intranasal delivery of a ghrelin mimetic engages the brain ghrelin signalling system in mice.

Ghrelin, the endogenous ligand of the growth hormone secretagogue receptor (GHSR), promotes food intake, other feeding behaviours and stimulates growth hormone (GH) release from the pituitary. Growth hormone secretagogues (GHS), such as GHRP-6 and MK-0677, are synthetic GHSR ligands that activate orexigenic Neuropeptide Y neurons that co-express Agouti-Related Peptide (AgRP) in the arcuate nucleus of the hypothalamus when administered systemically. Systemic GHRP-6 also stimulates GH release in humans and rats.

Low Bacterial Biomass in Human Pancreatic Cancer and Adjacent Normal Tissue.

The gut microbiome plays an important role in the carcinogenesis of luminal gastrointestinal malignancies and response to antineoplastic therapy. Preclinical studies have suggested a role of intratumoral gammaproteobacteria in mediating response to gemcitabine-based chemotherapy in pancreatic ductal adenocarcinoma (PDAC). To our knowledge, this is the first study to evaluate the impact of the PDAC microbiome on chemotherapy response using samples from human pancreatic tumor resections.

The Effect of Resistance and/or Aerobic Training on Quality of Life, Fitness, and Body Composition in Prostate Cancer Patients-A Systematic Review and Meta-Analysis.

: Prostate cancer (PC) and its treatment are often associated with side effects such as fatigue, muscle loss, and diminished quality of life (QoL). Physical exercise, particularly resistance training (RT) and aerobic training (AT), has been suggested as a strategy to mitigate these effects. However, the comparative efficacy of RT, AT, and combined RT/AT on QoL, body composition, physical fitness, and laboratory markers in PC patients is still insufficiently understood.
