Spatial transcriptomic technologies have been developed rapidly in recent years. The addition of spatial context to expression data holds the potential to revolutionize many fields in biology. However, the lack of computational tools remains a bottleneck that is preventing the broader utilization of these technologies. Recently, we have developed Giotto as a comprehensive, generally applicable, and user-friendly toolbox for spatial transcriptomic data analysis and visualization. Giotto implements a rich set of algorithms to enable robust spatial data analysis. To help users get familiar with the Giotto environment and apply it effectively in analyzing new datasets, we will describe the detailed protocols for applying Giotto without any advanced programming skills. © 2022 Wiley Periodicals LLC. Basic Protocol 1: Getting Giotto set up for use Basic Protocol 2: Pre-processing Basic Protocol 3: Clustering and cell-type identification Basic Protocol 4: Cell-type enrichment and deconvolution analyses Basic Protocol 5: Spatial structure analysis tools Basic Protocol 6: Spatial domain detection by using a hidden Markov random field model Support Protocol 1: Spatial proximity-associated cell-cell interactions Support Protocol 2: Assembly of a registered 3D Giotto object from 2D slices.

Mesothelioma is a lethal cancer of the serosal lining of the body cavities. Risk factors include environmental and genetic factors. Asbestos exposure is considered the principal environmental risk factor, but other carcinogenic mineral fibers, such as erionite, also have a causal role.

In vivo calcium imaging in freely moving rats using miniscopes provides valuable information about the neural mechanisms of behavior in real time. A gradient index (GRIN) lens can be implanted in deep brain structures to relay activity from single neurons. While such procedures have been successful in mice, few reports provide detailed procedures for successful surgery and long-term imaging in rats, which are better suited for studying complex human behaviors.

Background: Although physical activity (PA) has been linked to cognitive health, the nuanced relationships between different dimensions of PA and cognitive impairment remain inconclusive. This study investigated associations between late-life PA levels, midlife-to-late-life activity patterns, and cognitive impairment in Chinese older adults, considering potential moderation by apolipoprotein E (APOE) ε4 genotype.
Methods: We analyzed baseline data from 6,899 participants (median age 68 years, 55.

The circadian clock genes are known important for kidney development, maturation and physiological functions. However, whether and how they play a role in renal regeneration remain elusive. Here, by using the single cell RNA-sequencing (scRNA-seq) technology, we investigated the dynamic gene expression profiles and cell states after acute kidney injury (AKI) by gentamicin treatment in zebrafish.

Introduction: Type 2 diabetes mellitus (T2DM) is a major burden on public health worldwide. To reduce adverse events and complications, effective T2DM self-management is required. Self-management and glycaemic control are generally poorer in lower educated people compared with higher educated people.
