Can non-human primates extract the linear trend from a noisy scatterplot?

iScience

January 2025

Cognitive Neuroimaging Unit, CEA, INSERM, Université Paris-Saclay, NeuroSpin Center, 91191 Gif/Yvette, France.

Recent studies showed that humans, regardless of age, education, and culture, can extract the linear trend of a noisy scatterplot. Although this capacity looks sophisticated, it may simply reflect the extraction of the principal trend of the graph, as if the cloud of dots was processed as an oriented object. To test this idea, we trained Guinea baboons to associate arbitrary shapes with the increasing or decreasing trends of noiseless and noisy scatterplots, while varying the number of points, the noise level, and the regression slope.

Background: Locoregional therapy (LRT) in patients with hepatocellular carcinoma (HCC) before liver transplantation (LT) has a role in improving the tumor biology and post-LT survival outcome apart from downstaging and bridging. We retrospectively analyzed our database of adult living donor liver transplants (LDLT) for HCC, to compare the survival outcomes in Group-1 (upfront-LT, HCC within Milan/UCSF/AFP<1000 ng/ml) and Group-2 (LT post-LRT, HCC beyond UCSF/irrespective of tumor burden with AFP>1000 ng/ml). We also explored the risk factors for recurrence on follow-up.

Study based on bibliometric analysis: potential research trends in fluid management for sepsis.

Front Med (Lausanne)

January 2025

Department of Critical Care Medicine, Qilu Hospital, Shandong University, Qingdao, China.

Objective: To investigate the potential and evolving trends in fluid management for patients with sepsis, utilizing a bibliometric approach.

Methods: Scholarly articles pertaining to fluid therapy for sepsis patients were extracted from the Web of Science (WoS) database as of June 1, 2024. The R software package, "Bibliometrix," was utilized to scrutinize the primary bibliometric attributes and to construct a three-field plot to illustrate the relationships among institutions, nations, and keywords.

A bibliometric and visualization analysis of electrochemical biosensors for early diagnosis of eye diseases.

Front Med (Lausanne)

January 2025

Department of Anatomy and Neurobiology, School of Basic Medical Sciences, Central South University, Changsha, China.

Electrochemical biosensors can provide an economical, accurate and rapid method for early screening of disease biomarkers in clinical medicine due to their high sensitivity, selectivity, portability, low cost and easy manufacturing, and multiplexing capability. Tear, a fluid naturally secreted by the human body, is not only easily accessible but also contains a great deal of biological information. However, no bibliometric studies focus on applying electrochemical sensors in tear/eye diseases.

The strong correlation between reproductive life cycle type and chromosome numbers in green plants has been a long-standing mystery in evolutionary biology. Within green plants, the derived condition of heterosporous reproduction has emerged from the ancestral condition of homospory in disparate locations on the phylogenetic tree at least 11 times, of which three lineages are extant. In all green plant lineages where heterospory has emerged, there has been a significant downsizing in chromosome numbers.
