POSTMEAL OPTOGENETIC INHIBITION OF DORSAL HIPPOCAMPAL PRINCIPAL NEURONS INCREASES FUTURE INTAKE IN A TIME-DEPENDENT MANNER.

Neurobiol Learn Mem 2021 Jun 8:107478. Epub 2021 Jun 8.

Neuroscience Institute; Department of Psychology, Georgia State University, Atlanta, GA, 30303, USA.

Research involving human participants indicates that memories of recently eaten meals limit how much is eaten during subsequent eating episodes; yet, the brain regions that mediate the inhibitory effects of ingestion-related memory on future intake are largely unknown. We hypothesize that dorsal hippocampal (dHC) neurons, which are critical for episodic memories of personal experiences, mediate the inhibitory effects of ingestion-related memory on future intake. Our research program aimed at testing this hypothesis has been influenced in large part by our mentor James McGaugh and his research on posttraining manipulations. Read More

High-grade Papillary Early Gastric Carcinoma With High Risk for Lymph Node Metastasis and Poor Prognosis: A Clinicopathologic Study of 96 Cases Among 1136 Consecutive Radical Gastrectomies.

Am J Surg Pathol 2021 Jun 10. Epub 2021 Jun 10.

Departments of Pathology Oncology Gastroenterology of the Affiliated Changzhou Second People's Hospital of Nanjing Medical University, Changzhou Department of Pathology of the First Affiliated Hospital of Soochow University, Suzhou, China Department of Pathology and Laboratory Medicine of Veterans Affairs Boston Healthcare System, Harvard Medical School and Brigham and Women's Hospital, MA.

Papillary early gastric carcinoma (EGC) is believed to have a low risk of lymph node metastasis (LNM) and thus can be resected endoscopically. We observed anecdotally that some papillary EGC tumors showed conspicuous high-grade dysplastic features, but the significance of these observations is unknown. In this bicenter study we investigated papillary EGCs that were divided into high-grade (n=96) and low-grade (n=118) groups among 1136 consecutive EGC radical resection cases. Read More

Expert Rev Clin Pharmacol 2021 Jun 11. Epub 2021 Jun 11.

Department of Oncology, San Bortolo General Hospital, AULSS8 Berica, Vicenza, Italy.

Introduction: Although standard doublet chemotherapy represents the upfront gold standard to increase survival and improve quality of life of gastric cancer patients, overall improvements in long-term outcomes are modest and novel treatments are urgently needed. Among these, immunotherapy is an increasingly attractive option.

Areas Covered: A number of clinical trials have shown that checkpoint inhibitors may be of value, but many unclear issues remain controversial and should be promptly untangled. Read More

Data on the in-vitro digestibility of acid gels prepared from brewers' spent grain protein isolates.

Data Brief 2021 Aug 21;37:107160. Epub 2021 May 21.

Environmental Research and Innovation (ERIN) Department, Luxembourg Institute of Science and Technology (LIST), 5 avenue des Hauts Fourneaux, L-4362, Esch-sur-Alzette, LUXEMBOURG.

Brewers' Spent Grain (BSG) is the primary waste of the beer brewing process, which comprises a plethora of nutritionally appealing ingredients such as proteins, dietary fibres, essential lipids and micronutrients. In our previous study [1], the acid-induced gelation capacity of BSG protein isolate as influenced by the thermal pre-treatment severity was systematically investigated. In the present work, we aimed at providing a dataset outlining the gastrointestinal fate of the acid gels under simulating pre-absorptive digestion conditions adopting the INFOGEST static in-vitro digestion protocol.
