Ultra‐Fine 3D Bioprinting of Dynamic Hyaluronic Acid Hydrogel for in Vitro Modeling
Advanced Materials, EarlyView.3D bioprinting merges tissue engineering and additive manufacturing to create biological structures. A bioink is developed by modifying hyaluronic acid, a natural extracellular matrix polymer, with cysteine. Potassium iodide is later added to tune gelation kinetics, enabling fine printing with a 32G needle.

A Study of Quantitative Correlations Between Crucial Bio-markers and the Optimal Drug Regimen of Type-I Lepra Reaction [PDF]
arXivLeprosy (Hansen's) is a disease caused by Mycobacterium leprae. This disease slowly leads to occurrence of leprae reactions which mainly damage peripheral nervous system which cause loss of organs. We can prevent occurring leprae reactions by monitoring the bio-markers involved in it.

Assessing the Level of Autonomic Nervous Activity for Effective Biofeedback Training [PDF]
arXiv, 2019 This paper proposes a prototype of a new biofeedback training based on mathematical models of cardiovascular control. For this purpose we develop a low-cost device that is able to record and process arterial pulse wave via photoplethysmograph and skin temperature on the peripheral part of the arm. A benchmark analysis of our device against a registered

Kazan medical journal, 1935 Various etiological factors infection, trauma, exposure to cold cause diseases of the peripheral nervous system. A pathogenic agent, acting on a particular site, activates a certain mechanism that passes through certain phases and creates a disease syndrome. Is there a local specificity of this mechanism, uniformity in the reactions arising under the
