The aim was to investigate the potential effect of functional milk fat (FMF), naturally enriched in conjugated linoleic acid, on the prevention of liver lipid accumulation and some biochemical mechanisms involved in the liver triacylglycerol (TAG) regulation in high-fat (HF) fed rats. Male Wistar rats were fed (60 days) with S7 (soybean oil, 7%) or HF diets S30 (soybean oil, 30%), MF30 (soybean oil, 3% + milk fat -MF-, 27%) or FMF30 (soybean oil, 3% + FMF, 27%). Nutritional parameters, hepatic fatty acid (FA) composition, liver and serum TAG levels, hepatic TAG secretion rate (TAG-SR), lipoprotein lipase (LPL) activity in adipose tissue and muscle, activities and/or mRNA levels of lipogenic and β-oxidative enzymes, and mRNA levels of transcription factors and FA transport proteins were assessed. The hepatic lipid accumulation induced by the S30 diet was associated with increased mRNA levels of FA transporters; and it was prevented by FMF through an increase in the hepatic TAG-SR, carnitine palmitoyltransferase-1a activity and peroxisome proliferator-activated receptor alpha mRNA levels, as well as by a reduction of the mRNA levels of FA transporters. The hypotriacylglyceridaemia observed in S30 was related with an increased LPL activity in adipose tissue and it was reverted by FMF through the increased hepatic TAG-SR. In brief, FMF prevented the liver lipid accumulation induced by HF diets by increasing the hepatic TAG-SR and β-oxidation, and reducing the hepatic FA uptake. The increased hepatic TAG-SR induced by FMF could be responsible for the attenuation of serum TAG alterations.The concept of Eshelby untwisting, the effect of an axial screw dislocation driving an intrinsically twisted nanocrystal towards a straighter configuration more consistent with long-range translational symmetry, is introduced here. Force-field simulations of nanorods built from the enantiomorphous (space groups, P3121 and P3221) crystal structures of benzil (C6H5-C(O)-C(O)-C6H5) were previously shown to twist in opposite directions, even in the absence of dislocations. ACY-738 ic50 Here, both right- and left-handed screw dislocations were introduced into benzil nanorods in silico. For rods built from the P3221 enantiomorph, dislocations with negative Burgers vectors increased the right-handed twisting already present in the intrinsically twisted structures without dislocations, whereas dislocations with positive Burgers vectors drove the twisted structure back towards a straight configuration, untwisting. In the dynamic simulations, the P3221 helicoid endowed with a positive Burgers vector ultimately twisted back through the straight configuration, until a helicoid of opposite sense from that of the starting structure, was obtained. The bearing of these observations on the propensity of small crystals to adopt non-polyhedral morphologies is discussed.Phototreatment is at the leading edge of a research hot topic as a driving force for structural transformation, spectral and electromagnetism improvements, and the functional performance of nanomaterials. Light irradiation can excite surface plasmons in noble metal nanoparticles, create electron-hole pairs, and produce charge transfer in semiconductor substrates, which have led to it being widely used in surface-enhanced Raman spectroscopy (SERS) for life sciences, environmental protection, and biological analysis. Photo-induced enhanced Raman spectroscopy (PIERS) is a new technology developed on the basis of traditional SERS and has proven to be an efficient way to resolve several critical challenges thanks to its incomparable superiority for incontiguous operation, efficient charge separation and enrichment, and a large signal enhancement for a wide range of biomolecules at the trace level. This makes PIERS a powerful technique with very appealing and promising applications in various branches of analytical science. In this review, the enhancement mechanisms of PIERS are analyzed in comparison with SERS. Afterward, the parameters influencing the enhancement of PIERS, including the substrate, light irradiation, and relaxation are discussed in detail. Finally, some perspectives on further developments of PIERS are exemplified. The PIERS technique will continue to evolve and grow with new developments and its successful application in bioanalysis and life sciences.Thickness-modulated lateral MoS2 diodes with an extracted benchmark cutoff frequency (fc) of up to 126 GHz are implemented and fully characterised. Fabricated diodes demonstrate an on-off current ratio of more than 600 and a short circuit current responsivity at zero-bias of 7 A/W. The excellent performance achieved in our device is attributed to reduced contact resistance from using In/Au contacts and low junction capacitance due to the lateral device structure. In addition, the use of multilayer MoS2 crystals enabled relatively high current flow. Small- and large-signal models are extracted from DC and RF characterisation of the fabricated diode prototype. Extracted compact models are compared to the measured DC and S-parameters of the diode, demonstrating excellent matching between models and measurements. The presented diode is suitable for switching circuits and high frequency applications.Banana is one of the most nutritious fruits, as it is rich in carbohydrates, proteins, fatty acids, and minerals. Banana has been used in traditional medicines for managing coughs and colds, ulcers, burns, and diarrhea. Banana contains various bioactive compounds, such as alkaloids, phenols, flavonoids, tannins, and saponins, with reported therapeutic benefits, including antioxidant, anti-diabetic, anti-cancer, anti-inflammatory, and anti-microbial activities. The present review focuses on a comprehensive overview of the nutritional and biological properties and phytochemicals of different species of banana and its different parts. Although detailed characterization of the compounds that are present in many parts of the plant has been carried out, chemical profiling of the seed, pseudostem, and leaves of banana is lacking and requires further exploration. Moreover, the functions of the reported compounds were elucidated using computational tools, supporting their potential role in managing life-threatening diseases and physiological complications.
