Precision targeting of genetic variations in mixed bacterial cultures using CRISPR-Cas12a-programmed λ phages

open access: yesFrontiers in Microbiology
The CRISPR-Cas system, an adaptive immune mechanism in prokaryotes against bacteriophages, has been developed into a versatile tool for recognizing and cleaving target nucleic acid sequences.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Morphometry of Superior Sagittal Sinus and Its Clinical Significance

open access: yesIndian Journal of Neurosurgery
The position of the superior sagittal sinus (SSS) in the midline along the sagittal suture is still a debate among neurosurgeons. The aim of the study is to evaluate the diameter and deviation of the SSS at various landmarks in the midline.

Estimating present‐day European seasonal mean rainfall by combining historical data and climate model simulations, for risk assessment

open access: yesMeteorological Applications, 2021
Building risk models for present‐day climate requires an understanding of recent climate trends. To estimate the climate change driven component of recent rainfall trends in Europe, we introduce a novel methodology for combining trend estimates from ...

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

open access: yesMolecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Spectral Gaps of Almost Mathieu Operator in Exponential Regime [PDF]

open access: yes, 2013
For almost Mathieu operator $(H_{\lambda,\alpha,\theta}u)_n=u_{n+1}+u_{n-1}+2\lambda \cos2\pi(\theta+n\alpha)u_n$, the dry version of Ten Martini problem predicts that the spectrum $\Sigma_{\lambda,\alpha}$ of $ H_{\lambda,\alpha,\theta}$ has all gaps ...

Tumor mutational burden as a determinant of metastatic dissemination patterns

open access: yesMolecular Oncology, EarlyView.
This study performed a comprehensive analysis of genomic data to elucidate whether metastasis in certain organs share genetic characteristics regardless of cancer type. No robust mutational patterns were identified across different metastatic locations and cancer types.
