Rheological and Mechanical Properties and Spinning Behavior of a Starch-Based Biodegradable Polymer.

Over the last few years, the interest in biodegradable polymers has been increasing for several reasons, mainly because of the concerns about environmental protection and the reduction of emissions, especially those related to non-renewable fossil-based resources. Therefore, special attention has increased for the development of environment-friendly polymers such as biodegradable/compostable polymers, especially when they come from renewable resources, since this would help in further reducing energy consumption during their life cycle, as well as the overall environmental impact. Thus, every biopolymer should be accurately investigated in terms of its processability and main technological properties in order to find the most suitable applications.

An experimental laboratory-scale apparatus (bench and pilot scale) was set up for the simulation of a soil flushing intervention.

Mechanism of Hot-Carrier Photoluminescence in Sn-Based Perovskites.

Metal halide perovskites have shown exceptionally slow hot-carrier cooling, which has been attributed to various physical mechanisms without reaching a consensus. Here, experiment and theory are combined to unveil the carrier cooling process in formamidinium (FA) and caesium (Cs) tin triiodide thin films. Through impulsive vibrational spectroscopy and molecular dynamics, much shorter phonon dephasing times of the hybrid perovskite, which accounts for the larger blueshift in the photoluminescence seen at high excitation density for FASnI compared to CsSnI is reported.

CFD study on the effect of the baffles geometry in sedimentation efficiency in wastewater treatments through Large Eddy Simulations.

Sedimentation tanks represent one of the most important components of any water and wastewater treatment plants. The lack of knowledge of hydraulics in sedimentation tank leads to unnecessary capital and operating costs as well as water pollution in the form of excessive sludge. Improper and inadequate design cause overloading of filters, and lead to frequent backwashing, which in turn waste a significant percentage of treated water.

Fear appeals, individuals' cognitive-behavioral responses, and willingness to pay for safe water in fluoride-contaminated regions.

In rural areas with high fluoride concentrations in groundwater, affordable and effective de-fluoridation technologies can significantly reduce the likelihood of being affected by fluorosis-related illnesses, such as skeletal fluorosis. This is particularly significant in areas where groundwater is the primary or sole drinking water source, such as the Rift Valley of Tanzania. Despite the availability of technologies, people's use of de-fluoridation devices still needs to be improved.

New Structural Features of Isatin Dihydrothiazole Hybrids for Selective Carbonic Anhydrase Inhibitors.

Chemotherapeutic agents have remained the first-line treatment option for advanced-stage cancers when surgery or radiation therapy is not viable.

Ion Mobility QTOF-MS Untargeted Lipidomics of Human Serum Reveals a Metabolic Fingerprint for GNE Myopathy.

GNE myopathy, also known as hereditary inclusion body myopathy (HIBM), is a rare genetic muscle disorder marked by a gradual onset of muscle weakness in young adults. GNE myopathy (GNEM) is caused by bi-allelic variants in the UDP--acetylglucosamine 2-epimerase (UDP-GlcNAc 2-epimerase)/-acetylmannosamine kinase (ManNAc kinase) gene (), clinically resulting in the loss of ambulation within 10-20 years from the onset of the initial symptoms. The disease's mechanism is poorly understood and non-invasive biomarkers are lacking, hindering effective therapy development.

Biological Potential of Extracts: α-Glucosidase and Antibiofilm Activities In Vitro.

Type 2 diabetes (T2D), characterized by insulin resistance and β-cell dysfunction, requires continuous advancements in management strategies, particularly in controlling postprandial hyperglycemia to prevent complications. Current antidiabetics, which have α-amylase and α-glucosidase inhibitory activities, have side effects, prompting the search for better alternatives. In addition, diabetes patients are particularly vulnerable to yeast infections because an unusual sugar concentration promotes the growth of spp.

Dynamic overrepresentation of accumbal cues in food- and opioid-seeking rats after prenatal THC exposure.

The increasing prevalence of cannabis use during pregnancy has raised medical concerns, primarily related to Δ9-tetrahydrocannabinol (THC), which readily crosses the placenta and affects fetal brain development. Previous research has identified dopaminergic alterations related to maternal THC consumption. However, the consequences that prenatal cannabis exposure (PCE) has on striatum-based processing during reward pursuit have not been determined.

Functional Adaptation in the Brain Habenulo-Mesencephalic Pathway During Cannabinoid Withdrawal.

The mesolimbic reward system originating from dopamine neurons in the ventral tegmental area (VTA) of the midbrain shows a profound reduction in function during cannabinoid withdrawal. This condition may underlie aversive states that lead to compulsive drug seeking and relapse. The lateral habenula (LHb) exerts negative control over the VTA via the GABA rostromedial tegmental nucleus (RMTg), representing a potential convergence point for drug-induced opponent processes.

A water playground for peptide re-assembly from fibrils to plates.

Short-peptide amyloid assembly and disassembly play crucial roles in various research fields, which range from addressing pathologies that lack therapeutic solutions to the development of innovative soft (bio)materials. Hydrogels from short peptides typically show thermo-reversible gel-to-sol transition, whereby fibrils disassemble upon heating, and re-assemble upon cooling down to room temperature (rt). Despite ongoing intense research studies in this area, the majority focus on peptide-peptide interaction and neglect the structuring role of water in peptide supramolecular behavior.

Acute stress induces different changes on the expression of CB1 receptors in the hippocampus of two lines of male rats differing in their response to stressors.

The stress-induced alterations in cognitive processes and psychiatric disorders can be accelerated when acute stressors challenge the hippocampal functions. To address this issue, we used Western Blot (WB) and immunohistochemistry assays to investigate the impact of acute forced swimming (FS) on the expression of the CB1 cannabinoid receptors (CB1R) in the hippocampus (HC) of the male outbred Roman High- (RHA) and Low-Avoidance (RLA) rat lines, one of the most validated genetic models for the study of behavior related to fear/anxiety and stress-induced depression. The distinct responses to FS confirmed the different behavioral strategies displayed by the two phenotypes when exposed to stressors, with RLA and RHA rats displaying reactive vs.

Effect of 5-alpha reductase inhibitors in animal models of Parkinson's disease.

Parkinson's disease (PD) is characterized by motor symptoms due to loss of brain dopamine and non-motor symptoms, including gastrointestinal disorders. Although there is no cure for PD, symptomatic treatments are available. L-Dopa is the gold standard PD therapy, but most patients develop dyskinesias (LID), which are challenging to manage.

Receptor and metabolic insights on the ability of caffeine to prevent alcohol-induced stimulation of mesolimbic dopamine transmission.

The consumption of alcohol and caffeine affects the lives of billions of individuals worldwide. Although recent evidence indicates that caffeine impairs the reinforcing properties of alcohol, a characterization of its effects on alcohol-stimulated mesolimbic dopamine (DA) function was lacking. Acting as the pro-drug of salsolinol, alcohol excites DA neurons in the posterior ventral tegmental area (pVTA) and increases DA release in the nucleus accumbens shell (AcbSh).
