Establishment and biological characterization of radioresistant colorectal cancer cell lines
Under ionizing radiation exposure, radiation‐sensitive cancer cells exhibit oxidative stress and DNA damage, while radiation‐resistant cancer cells exhibit strong antioxidant properties and DNA damage repair. Radiotherapy resistance is a major cause of recurrence and metastasis in colorectal cancer (CRC).

Carrier providers or carrier killers: the case of Cu defects in CdTe solar cells [PDF]
Defects play important roles in semiconductors for optoelectronic applications. Common intuition is that defects with shallow levels act as carrier providers and defects with deep levels are carrier killers. Here, taking the Cu defects in CdTe as an example, we show that shallow defects can play both roles.

The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

This review discusses the use of Surface‐Enhanced Raman Spectroscopy (SERS) combined with Artificial Intelligence (AI) for detecting antimicrobial resistance (AMR). Various SERS studies used with AI techniques, including machine learning and deep learning, are analyzed for their advantages and limitations.

Comparative study of adenosine 3′‐pyrophosphokinase domains of MuF polymorphic toxins
With the ultimate goal of understanding the association of toxin‐immunity modules to temperate phages, we characterized toxins from three prophages and examined cross‐protection from immunity proteins. The toxins exhibit adenosine 3′‐pyrophosphokinase activity and are toxic in Escherichia coli.

The role of natural killer cells in chronic myeloid leukemia
Chronic myeloid leukemia is a neoplasia resulting from a translocation between chromosomes 9 and 22 producing the BCR-ABL hybrid known as the Philadelphia chromosome (Ph).

FEM1B enhances TRAIL‐induced apoptosis in T lymphocytes and monocytes
FEM1B facilitates TRAIL‐induced apoptosis through distinct mechanisms in T lymphocytes and monocytes. In T lymphocytes, FEM1B engages with TRAF2, leading to a reduction in TRAF2 expression, which subsequently lessens TRAF2's inhibitory influence on caspase‐8.

Natural killer cells as an initial defense against pathogens. [PDF]
Natural killer (NK) cells serve as a crucial first line of defense against tumors and a diverse range of pathogens. Recognition of infection by NK cells is accomplished by the activation of receptors on the NK cell surface, which initiate NK cell ...
