Enhancing prostate cancer segmentation on multiparametric magnetic resonance imaging with background information and gland masks.

Background: The landscape of prostate cancer (PCa) segmentation within multiparametric magnetic resonance imaging (MP-MRI) was fragmented, with a noticeable lack of consensus on incorporating background details, culminating in inconsistent segmentation outputs. Given the complex and heterogeneous nature of PCa, conventional imaging segmentation algorithms frequently fell short, prompting the need for specialized research and refinement.

Purpose: This study sought to dissect and compare various segmentation methods, emphasizing the role of background information and gland masks in achieving superior PCa segmentation.

Structural basis of microRNA processing by Dicer-like 1.

MicroRNAs (miRNAs) are short non-coding RNAs that inhibit the expression of target genes by directly binding to their mRNAs. In animals, pri-miRNAs are cleaved by Drosha to generate pre-miRNAs, which are subsequently cleaved by Dicer to generate mature miRNAs. Instead of being cleaved by two different enzymes, both cleavages in plants are performed by Dicer-like 1 (DCL1).

Influence of Water Content on Mechanical Strength and Microstructure of Alkali-Activated Fly Ash/GGBFS Mortars Cured at Cold and Polar Regions.

Negative temperature curing is a very harmful factor for geopolymer mortar or concrete, which will decrease the strength and durability. The water in the geopolymer mixture may be frozen into ice, and the water content is a crucial factor. The purpose of this paper is to explore the influence of water content on the properties of alkali-activated binders mortar cured at -5 °C.

Estimation of hydraulic conductivity of saturated frozen soil from the soil freezing characteristic curve.

Knowledge of hydraulic conductivity is crucial for determining water movement in frozen soil, and the objective of this study is to introduce the soil freezing characteristic curve to estimate the hydraulic conductivity of saturated frozen soil. Based on the non-uniform tortuous capillary bundle model and the assumption that the ice was first formed in the pores with largest size, a physical infiltration model of saturated frozen soil was developed. On the basis of this physical infiltration model, a new approach for estimating the hydraulic conductivity of saturated frozen soil was developed by using the Hagen-Poiseuille equation and Darcy's law.

Structural analysis reveals a "molecular calipers" mechanism for a LATERAL ORGAN BOUNDARIES DOMAIN transcription factor protein from wheat.

LATERAL ORGAN BOUNDARIES DOMAIN (LBD) proteins, a family of plant-specific transcription factors harboring a conserved Lateral Organ Boundaries (LOB) domain, are regulators of plant organ development. Recent studies have unraveled additional pivotal roles of the LBD protein family beyond defining lateral organ boundaries, such as pollen development and nitrogen metabolism. The structural basis for the molecular network of LBD-dependent processes remains to be deciphered.

The Potential Roles and Advantages of Single Cell Sequencing in the Diagnosis and Treatment of Hematological Malignancies.

Hematological malignancies (HM) are a heterogeneous group of life-threatening hematological diseases. The heterogeneity and clonal evolution of HM subpopulations are the main obstacles for precise diagnoses, risk stratification, and even targeted therapies. Standard bulk-sample genomic examinations average total mutations from multiple subpopulations and conceal the clonal diversity that may play a significant role in HM progression.

A 3'-5' exonuclease activity embedded in the helicase core domain of Candida albicans Pif1 helicase.

3'-5' exonucleases are frequently found to be associated to polymerases or helicases domains in the same enzyme or could function as autonomous entities. Here we uncovered that Candida albicans Pif1 (CaPif1) displays a 3'-5' exonuclease activity besides its main helicase activity. These two latter activities appear to reside on the same polypeptide and the new exonuclease activity could be mapped to the helicase core domain.
