Surface Plasmon Resonance-Based Biosensors for Advanced Bioprocess Monitoring
Biomanufacturers are being incited by regulatory agencies to transition from a quality by testing framework, where they extensively test their product after their production, to more of a quality by design or even quality by control framework. This requires powerful analytical tools and sensors enabling measurements of key process variables and/or product quality attributes during production, preferably in an online manner. As such, the demand for monitoring technologies is rapidly growing. In this context, researchers believe surface plasmon resonance (SPR)-based biosensors can play a role in enabling the development of improved bioprocess monitoring and control strategies.

Two-Dimensional Quantum Billiards
Two-dimensional quantum billiards are one of the most important paradigms for exploring the connection between quantum and classical worlds. Researchers are mainly focused on nonintegrable and irregular shapes to understand the quantum characteristics of chaotic billiards. The emergence of the scarred modes relevant to unstable periodic orbits (POs) is one intriguing finding in nonintegrable quantum billiards. On the other hand, stable POs are abundant in integrable billiards. The quantum wavefunctions associated with stable POs have been shown to play a key role in ballistic transport.

Three Corpses
The sanshi 三尸 "Three Corpses" or sanchong 三蟲 "Three Worms" are a Daoist physiological belief that demonic creatures live inside the human body, and they seek to hasten the death of their host. These three supernatural parasites allegedly enter the person at birth, and reside in the three dantian "energy centers", respectively located within the head, chest, and abdomen. After their human host dies, they are freed from the body and become malevolent ghosts. The pernicious Three Corpses/Worms work to harm their host's health and fate by initiating sicknesses, inviting other disease-causing agents into the body, and reporting their host's transgressions to the gods. The Three Corpses are supposed to keep records of their host's misdeeds, ascend to tian "heaven" bimonthly on the night of Chinese sexagenary gengshen 庚申 "57th of the 60-day cycle" while the host is sleeping, and file reports to the Siming 司命 "Director of Destinies" who deducts a certain number of days from the person's life for each misdeed. One way of avoiding this bureaucratic snitching is to stay awake for the entire gengshen day and night, thus preventing the Three Corpses from leaving one's body (a belief later assimilated into the Japanese Kōshin 庚申 tradition). For a Daoist adept to achieve the longevity of a xian "transcendent; immortal", it was necessary to expel the Three Corpses from the body. Since these evil spirits feed upon decaying matter produced by grains being digested in the intestines, the practice of bigu "abstinence from grains and cereals" is the first step towards expelling them. Bigu alone will not eliminate the Three Corpses, but weakens them to the point where they can be killed with waidan alchemical drugs such as cinnabar, and ultimately eliminated through neidan meditation techniques.

Angiotensin II
Cardiovascular disease is the leading cause of morbidity and mortality in the western and developing world, and the incidence of cardiovascular disease is increasing with the longer lifespan afforded by our modern lifestyle.  Vascular diseases including coronary heart disease, high blood pressure, and stroke comprise the majority of cardiovascular disease and therefore represent a significant medical and socioeconomic burden on our society.  It is not be surprising that these conditions overlap and potentiate each other when we consider the many cellular and molecular similarities between them. At the molecular level, the vascular smooth muscle cell (VSMC) is the target, integrator, and effector cell of both atherogenic and the major effector protein of the hypertensive signal, Angiotensin II (Ang II).  Together, these signals can potentiate each other and prime the artery and exacerbate hypertension and atherosclerosis. Therefore, VSMC are the fulcrum in progression of these diseases and therefore, understanding the effects of atherogenic stimuli and Ang II on VSMC is  key to understanding and treating  atherosclerosis and hypertension.  In this review, we will examine studies in which hypertension and atherosclerosis intersect on the VSMC, and illustrate common pathways between these two diseases and vascular aging.

UFM1
Post-translational modification with Ubiquitin-like proteins represents a complex signaling language regulating virtually every cellular process. Among these post-translational modifiers is Ubiquitin-fold modifier (UFM1), which is covalently attached to its substrates through the orchestrated action of a dedicated enzymatic cascade. Originally identified to be involved embryonic development, its biological function remains enigmatic. Recent research reveals that UFM1 regulates a variety of cellular events ranging from DNA repair to autophagy and ER stress response implicating its involvement in a variety of diseases. Given the contribution of UFM1 to numerous pathologies, the enzymes of the UFM1 cascade represent attractive targets for pharmacological inhibition.

Syndecans and Pancreatic Ductal Adenocarcinoma
Pancreatic Ductal Adenocarcinoma (PDAC) is a fatal disease with poor prognosis because pa-tients rarely express symptoms in initial stages, which prevents early detection and diagnosis. Syndecans, a subfamily of proteoglycans, are involved in many physiological processes includ-ing cell proliferation, adhesion, and migration. Syndecans are physiologically found in many cell types and their interactions with other macromolecules enhance many pathways. In particu-lar, extracellular matrix components, growth factors, and integrins collect the majority of syndecans associations acting as biochemical, physical, and mechanical transducers. Syndecans are transmembrane glycoproteins, but occasionally their extracellular domain can be released from the cell surface by the action of matrix metalloproteinases, converting them into soluble molecules that are capable of binding distant molecules such as extracellular matrix (ECM) components, growth factor receptors, and integrins from other cells.

Arabidopsis MLO4 Interacts with CaM/CML
Here, we report the functional characterization of the MLO4 protein in Arabidopsis roots. The MLO4 was identified as interacting with CML12 in a screening for the interaction between the proteins from Arabidopsis MLO and calmodulin/calmodulin-like (CaM/CML) families using yeast two hybrid (Y2H) assays. Then, the interaction between MLO4 and CML12 was further verified by Luciferase Complementation Imaging (LCI) and Bimolecular Fluorescence Complementation (BiFC) assays. Genetic analysis showed that the mlo4, cml12, and mlo4 cml12 mutants displayed similar defects in root gravity response. These results imply that the MLO4 might play an important role in root gravity response through interaction with CML12. Moreover, our results also demonstrated that the interaction between the MLO and CaM/CML families might be conservative.

A Framework for Developing Environmental Justice Indicators
Environmental justice (EJ) is a broad discipline that attempts to understand and redress unfair exposure to unhealthy environmental conditions. EJ is often made measurable with indicators, however the capabilities and the limitations of EJ indicators can be difficult for policy makers to understand. Useful EJ indicators are invariably made up of at least two measures from a combination of the environment, demography, epidemiology or procedures elements. Furthermore, the way that measures are combined determines the type of EJ indicator that is created, enabling different facets of an issue to be understood.

Role of Short-Chain Fatty Acids in COPD
Chronic obstructive pulmonary disease (COPD) is a widespread socially significant disease. The development of COPD involves the innate immune system. The regulation of the innate lung immune system is related to the gut microbiota. This connection is due to the production by gut microorganisms of short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate. Nutritional disturbances and changes in the structure of the intestinal microbiota lead to a decrease in SCFAs production and their effect on pulmonary immunity. The presence of a metabolic and immune axis linking the lungs and gut plays an important role in the pathogenesis of COPD.

Synergies between Shallow Geothermal Energy and DHC Networks
According to the EU Directive 2018/2001, “geothermal energy” means strictly “energy stored in the form of heat beneath the surface of solid earth”. Shallow geothermal energy (SGE) is a specific case where the temperature of the resources is generally under 30 °C (also known as “very-low enthalpy geothermal energy”). The heat exchange with surface-water bodies (sea, lakes, or rivers), ambient air, and sewage water is considered as “ambient energy” in the same document.

Application of Waste Powder in Pervious Concrete
According to the literature, the annual global consumption of concrete had reached 25 billion tons in 2009. Cement is an important component of concrete, and the global cement production is approximately 4.1 billion tons per year. However, the production of 1 ton of Portland cement can emit between 730–850 kg of CO2. Waste powder is mainly derived from the waste of industrial production or volcanic activities. If not reutilized, such waste powder will cause serious environmental problems.
