Sustainable Synthesis of MXenes
MXenes provide a major drawback involving environmentally harmful and toxic substances for its general fabrication in large-scale production and employing a high-temperature solid-state reaction followed by selective etching. Meanwhile, how MXenes are synthesized is essential in directing their end uses. Therefore, making strategic approaches to synthesize greener, safer, more sustainable, and more environmentally friendly MXenes is imperative to commercialize at a competitive price.

Benefit of Soybean-Derived Bioactive Peptides
Peptides present in foods have a wide range of physiological functions, including as anticancer agents and in lowering blood pressure and serum cholesterol levels, enhancing immunity, and promoting calcium absorption. Soy protein can be partially hydrolyzed enzymatically to physiologically active soy (or soybean) peptides (SPs), which not only exert physiological functions but also help amino acid absorption in the body and reduce bitterness by hydrolyzing hydrophobic amino acids from the C- or N-terminus of soy proteins. They also possess significant gel-forming, emulsifying, and foaming abilities. SPs are expected to be able to prevent and treat atherosclerosis by inhibiting the reabsorption of bile acids in the digestive system, thereby reducing blood cholesterol, low-density lipoprotein, and fat levels.

Soil Constraints in an Arid Environment
Arid environments are characterized by a higher evaporation than precipitation, as well as persistent water shortages, frequent droughts, high climate variability, and high wind velocity. These soil constraints can be ameliorated and the crop yields increased through case-specific optimization of irrigation and drainage management, enhancing the native beneficial soil microbes, and combinations of soil amendments, conditioners, and residue management.

Microbial and Commercial Enzymes in Beverage Production Process
Enzymes are highly effective biocatalysts used in various industrial processes, playing a key role in winemaking and in other fermented beverages. Many of the enzymes used in fermentation processes have their origin in fruits, in the indigenous microbiota of the fruit, and in the microorganisms present during beverage processing. Besides naturally occurring enzymes, commercial preparations that usually blend different activities are used (glucosidases, glucanases, pectinases, and proteases, among others).

Artemisia absinthium L.
Artemisia absinthium – wormwood (Asteraceae) – is a very important species in the history of medicine, formerly described in medieval Europe as “the most important master against all exhaustions”. It is a species known as a medicinal plant in Europe and also in West Asia and North America. The raw material obtained from this species is Artemisiae herba and Artemisiae absinthium aetheroleum. The main substances responsible for the biological activity of the herb are: the essential oil, bitter sesquiterpenoid lactones, flavonoids, another bitterness-imparting compounds, azulenes, phenolic acids, tannins and lignans. In the official European medicine, the species is used in both allopathy and homeopathy. In the traditional Asian and European medicine, it has been used as an effective agent in gastrointestinal ailments and also in the treatment of helminthiasis, anaemia, insomnia, bladder diseases, difficult-to-heal wounds, and fever. Today, numerous other directions of biological activity of the components of this species have been demonstrated and confirmed by scientific research, antiprotozoal, antibacterial, antifungal, anti-ulcer, hepatoprotective, anti-inflammatory, immunostimulatory, cytotoxic, analgesic, neuroprotective, antidepressant, procognitive, neurotrophic, and cell membrane stabilizing activities. A. absinthium is also making a successful career as a cosmetic plant. In addition, the importance of this species as a spice plant and valuable additive in the alcohol industry (famous absinthe and vermouth-type wines) has not decreased. The species has also become an object of biotechnological research.

Gastric Pentadecapeptide BPC 157 in Brain–Gut Axis/Gut–Brain Axis
BPC 157 therapy by rapidly activated collateral pathways counteracted the vascular and multiorgan failure concomitant to major vessel occlusion and, similar to noxious procedures, reversed initiated multicausal noxious circuit of the occlusion/occlusion-like syndrome. Severe intracranial (superior sagittal sinus) hypertension, portal and caval hypertensions, and aortal hypotension were attenuated/eliminated. Counteracted were the severe lesions in the brain, lungs, liver, kidney, and gastrointestinal tract. In particular, progressing thrombosis, both peripherally and centrally, and heart arrhythmias and infarction that would consistently occur were fully counteracted and/or almost annihilated.

RAS/RAF/MAPK/ERK Signaling Pathways of Vascular Anomalies
Vascular anomalies (VAs) are morphogenesis defects of the vascular system (arteries, capillaries, veins, lymphatic vessels) singularly or in complex combinations, sometimes with a severe impact on the quality of life. The main function of the RAS/RAF/MAPK/ERK signaling pathway, also called the “proliferation pathway”, is to transduce signals from the extracellular milieu to the cell nucleus where specific genes are activated for cell cycle regulation, proliferation, and cell migration.

Microbially-Induced Desaturation and Carbonate Precipitation
Microbially induced carbonate precipitation (MICP) has been proposed as a sustainable approach to solve various environmental, structural, geotechnical and architectural issues. In the last decade, a ubiquitous microbial metabolism, nitrate reduction (also known as denitrification) got attention in MICP research due to its unique added benefits such as simultaneous corrosion inhibition in concrete and desaturation of porous media. The latter even upgraded MICP into a more advanced concept called microbially induced desaturation and precipitation (MIDP) which is being investigated for liquefaction mitigation.

Flexible Working Arrangements and Turnover Intentions
The problem of employee turnover has been investigated in recent years because more and more countries and organizations are faced with the lack of an adequate labor force. The new generation of employees (Y and Z generations), contemporary political, social, and economic challenges, and the COVID-19 pandemic have raised new issues in human resource management (HRM), especially concerning turnover intentions. In such situations, companies need to create working conditions that will attract, motivate, and retain employees. One possible response is the usage of flexible working arrangements (FWAs) as a more flexible way of organizing traditional jobs and working positions; these arrangements allow employees more possibilities to maintain work–life balance.

Sound Trap
A sound trap, also known as a duct silencer, sound attenuator, or muffler, is a special acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces. In its simplest form, a sound trap consists of an baffle within the ductwork. These baffles often contain sound-absorbing materials. The physical dimensions and baffle configuration of sound traps are selected to attenuate a specific range of frequencies. Unlike conventional internally-lined ductwork, which is only effective at attenuating mid- and high-frequency noise, sound traps can achieve broader band attenuation in relatively short lengths. Certain types of sound traps are essentially a Helmholtz resonator used as a passive noise-control device.

Microbial Fuel Cells in Treatment  from Wastewater
The treatment of wastewater is an expensive and energy-extensive practice that not only ensures the power generation requirements to sustain the current energy demands of an increasing human population but also aids in the subsequent removal of enormous quantities of wastewater that need to be treated within the environment. Thus, renewable energy source-based wastewater treatment is one of the recently developing techniques to overcome power generation and environmental contamination issues. In wastewater treatment, microbial fuel cell (MFC) technology has demonstrated a promising potential to evolve as a sustainable approach, with the simultaneous recovery of energy and nutrients to produce bioelectricity that harnesses the ability of electrogenic microbes to oxidize organic contaminants present in wastewater.

Physicochemical Properties and Composition of Different Honey
Honey is considered to be a functional food with health-promoting properties. However, its potential health benefits can be affected by individual composition that varies between honey types. Although studies describing the health benefits of Tualang honey (TH), Kelulut honey (KH), and Sidr honey (SH) are scarce, these honey types showed a comparable therapeutic efficacy to Manuka honey (MH). Findings showed that these honeys have antibacterial, antifungal, antiviral, antioxidant, antidiabetic, antiobesity, anticancer, anti-inflammatory and wound-healing properties and effects on the cardiovascular system, nervous system, and respiratory system.

Use of Oncept Melanoma Vaccine in Veterinary Patients
The Oncept melanoma vaccine is xenogeneic DNA vaccine targeting tyrosinase. It is USDA approved for treatment of stage II to III canine oral melanoma and is also used off-label for melanomas arising in other locations and in other species. While the vaccine appears safe, the published data is mixed as to whether it provides a survival benefit, and the use of the vaccine is somewhat controversial in the veterinary oncology community.While the vaccine appears to be safe, there does not appear to be evidence that it improves outcome when used. Further studies to better evaluate its use in patients, and exploration of other treatment options for melanoma, need to be performed.

Functions of Circular RNAs
Circular RNAs (circRNAs) are a distinctive class of regulatory non-coding RNAs characterised by the presence of covalently closed ends. They are evolutionary conserved molecules, and although detected in different tissues, circRNAs resulted specifically enriched in the nervous system, where they might play an important role in neuronal specification and activity.  Notably, deregulation of circRNAs expression has been linked with various neurological disorders. Little is known about circRNA mode of action, the few species characterized have been shown to act as molecular decoy for microRNAs (miRNAs) or RNA binding proteins (RBPs), to control transcription of their host genes and, although classify as ncRNAs, some of them hold the capacity to direct synthesis of short peptides/proteins.
