Liver organoids: modelling complexity in homeostasis and disease
FEBS Letters, EarlyView.Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

A Novel LSB Steganography Technique Using Image Segmentation [PDF]
Journal of Universal Computer ScienceSteganography is a process to hide data inside a cover file mostly used in media files like image, video, and audio files. Least significant bit (LSB) steganography is a technique where the least significant bits of pixels are used for information hiding.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network
FEBS Letters, EarlyView.Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Approaches to obtaining fingerprints of steganography tools which embed message in fixed positions
Forensic Science International: Reports, 2019 Recently, more and more steganography tools are exploited to embed malicious code into images by attackers, which bring harm to society. Thus, it has been a tricky problem, for which needs to detect the stego-images correctly.

A Hybrid Image Steganography Method
International Journal of Recent Technology and Engineering (IJRTE), 2019 This is age of fast communication and data revolution. Huge amount of data is transmitted and received in every second utilizing the current infrastructure. Providing the security and maintaining integrity of the data while it is being transferred through the public channels is a challenging task. Steganography can be used in this purpose by concealing

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
