Nonpyrogenic charring of Late Pleistocene large mammal remains in northeastern Russia

Boreas, Volume 51, Issue 2, Page 481-495, April 2022., 2022
Mammal remains preserved in the permafrost zone often bear traces of postmortem transformations, reflecting aspects of the palaeoenvironment and the processes that took place during the accumulation of host sediments. Multidisciplinary studies including radiocarbon dating, infrared spectroscopy, and microfossil analyses and grain size of infilling ...

Ecological interactions in glacier environments: a review of studies on a model Alpine glacier. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Glaciers host a variety of cold‐adapted taxa, many of which have not yet been described. Interactions among glacier organisms are even less clear. Understanding ecological interactions is crucial to unravelling the functioning of glacier ecosystems, particularly in light of current glacier retreat.

C‐reactive protein : albumin ratio in patients with resectable intrahepatic cholangiocarcinoma

BJS Open, Volume 4, Issue 6, Page 1146-1152, December 2020., 2020
This study showed that a high C‐reactive protein : albumin ratio (CAR) is an independent predictor of poor recurrence‐free survival in patients with intrahepatic cholangiocarcinoma (ICC). The results also suggest that patients with ICC with a high CAR had a more aggressive tumour behaviour, including a larger tumour size, higher frequency of ...

Ki67 expression at Kasai portoenterostomy as a prognostic factor in patients with biliary atresia

BJS Open, Volume 4, Issue 5, Page 873-883, October 2020., 2020
No consensus exists for predicting outcomes after Kasai portoenterostomy (KP) using liver histological findings. Ki67 (clone, MIB‐1) expression in liver parenchyma was measured by means of immunohistochemical staining of samples from five living donors and 35 patients with biliary atresia to assess its value in predicting KP outcomes.

Simulated model of RAPID concept: highlighting innate inflammation and liver regeneration

BJS Open, Volume 4, Issue 5, Page 893-903, October 2020., 2020
The mechanism of RAPID‐associated liver regeneration and its regulation remains unclear. A RAPID model in rats was developed involving cold ischaemia and reperfusion of the selected future liver remnant, portal vein ligation of the remaining segments during step I, and resection of the deportalized lobes during step II.

Preoperative imaging for colorectal liver metastases: a nationwide population‐based study

BJS Open, Volume 4, Issue 4, Page 605-621, August 2020., 2020
A nationwide population‐based overview from 2014 to 2018 in the Netherlands showed an increased use of contrast‐enhanced MRI and decreased use of PET–CT. There was significant hospital variation in the use of both MRI and PET–CT. Wide variation in the use of preoperative MRI and FDG‐PET‐CT Background In patients with colorectal liver metastases (CRLM ...

Bryo-Activities: A Review on How Bryophytes Are Contributing to the Arsenal of Natural Bioactive Compounds against Fungi

Plants, 2021
Usually regarded as less evolved than their more recently diverged vascular sisters, which currently dominate vegetation landscape, bryophytes seem having nothing to envy to the defensive arsenal of other plants, since they had acquired a suite of ...

Outcomes for high‐risk hepatoblastoma in a resource‐challenged setting

BJS Open, Volume 4, Issue 4, Page 630-636, August 2020., 2020
The outcomes of children with high‐risk hepatoblastoma were assessed in the setting of a resource‐challenged nation, where access to organized chemotherapy and liver transplantation remains limited for the underprivileged. Excellent results were demonstrated.
