This review explores the progressive domain of network pharmacology and its potential to revolutionize therapeutic approaches for Interstitial Lung Diseases (ILDs), a collective term encompassing Interstitial Pneumonia, Pneumoconiosis, Connective Tissue Disease-related ILDs, and Sarcoidosis. The exploration focuses on the profound legacy of traditional medicines, particularly Ayurveda and Traditional Chinese Medicines (TCM), and their largely unexplored capacity in ILD treatment. These ancient healing systems, characterized by their holistic methodologies and multifaceted treatment modalities, offer a promising foundation for discovering innovative therapeutic strategies.

The secretion rate of albumin is a key indicator of function in liver tissue models used for hepatotoxicity and pharmacokinetic testing. However, it is not generally clear how to determine molecular secretion rates from measurements of the molecular concentration in supernatant media. Here, we develop computational and analytical models of molecular transport in an experimental system that enable determination of albumin secretion rates based on measurements of albumin concentration in supernatant media.

Psychological problems are prevalent in people with inflammatory bowel diseases but are not routinely addressed. To improve recognition, three psychological screening tools were integrated into clinical management software (Crohn Colitis Care). In the first 6 months, completion rates varied between participating sites, and approximately 23-34% of respondents scored in moderate or higher ranges for psychological distress.

Neuromorphic visual systems emulating biological retina functionalities have enormous potential for in-sensor computing, with prospects of making artificial intelligence ubiquitous. Conventionally, visual information is captured by an image sensor, stored by memory units, and eventually processed by the machine learning algorithm. Here, we present an optoelectronic synapse device with multifunctional integration of all the processes required for real time object identification.

Optoelectronic synapses combine the functionalities of a non-volatile memory and photodetection in the same device, paving the path for the realization of artificial retina systems which can capture, pre-process, and identify images on the same platform. Graphene/TaO/graphene phototransistor exhibits synapse characteristics when visible electromagnetic radiation of wavelength 405 nm illuminates the device. The photocurrent is retained after light withdrawal when positive gate voltage is applied to the device.

Brain-inspired computing enabled by memristors has gained prominence over the years due to the nanoscale footprint and reduced complexity for implementing synapses and neurons. The demonstration of complex neuromorphic circuits using conventional materials systems has been limited by high cycle-to-cycle and device-to-device variability. Two-dimensional (2D) materials have been used to realize transparent, flexible, ultra-thin memristive synapses for neuromorphic computing, but with limited knowledge on the statistical variation of devices.

Article Synopsis
  • Higher levels of anti-TNF drugs (infliximab and adalimumab) are linked to better clinical healing of Crohn's perianal fistulas and improved radiologic outcomes.
  • A study analyzed 193 patients with perianal fistulising Crohn's disease, comparing drug levels and MRI results to determine healing status and radiologic remission.
  • Results showed that patients with higher drug levels had significantly better radiologic healing and remission scores, indicating a positive correlation between drug concentration and reduced disease activity.

Purpose: The aim of this study ws to evaluate prognostic factors associated with final visual outcome in patients with congenital cataract associated with congenital rubella syndrome.

Methods: A prospective interventional analysis of preoperative systemic and ocular features of 56 eyes of 28 seropositive infants of less than 12 months presenting to us with bilateral cataract was performed. All infants were surgically treated with cataract extraction, posterior capsulorhexis, and anterior vitrectomy followed by visual rehabilitation.

Optical data sensing, processing and visual memory are fundamental requirements for artificial intelligence and robotics with autonomous navigation. Traditionally, imaging has been kept separate from the pattern recognition circuitry. Optoelectronic synapses hold the special potential of integrating these two fields into a single layer, where a single device can record optical data, convert it into a conductance state and store it for learning and pattern recognition, similar to the optic nerve in human eye.

Two-dimensional (2D) layered materials and their heterostructures have recently been recognized as promising building blocks for futuristic brain-like neuromorphic computing devices. They exhibit unique properties such as near-atomic thickness, dangling-bond-free surfaces, high mechanical robustness, and electrical/optical tunability. Such attributes unattainable with traditional electronic materials are particularly promising for high-performance artificial neurons and synapses, enabling energy-efficient operation, high integration density, and excellent scalability.

Background: Adherence to evidence-based management is variable in inflammatory bowel disease (IBD), which leads to worse patient outcomes and higher healthcare utilization. Solutions include electronic systems to enhance care, but these have often been limited by lack of clinician design input, poor usability, and low perceived value. A cloud-based IBD-specific clinical management software - 'Crohn's Colitis Care' (CCCare) was developed by Australia and New Zealand Inflammatory Bowel Disease Consortium clinicians and software developers to improve this.
