Denture Adhesives are commonly used by denture wearers to enhance the retentive ability of their dentures however, little is known about the efficacy of these materials. To compare the retentive ability of three different commercially available denture adhesives. To find out the best available denture adhesive material. An in vitro investigation to evaluate the retentive ability of three commercially available denture adhesive powders and two adhesive pastes was conducted. The adhesion and cohesion that developed between the glass surface and acrylic resin samples when the various materials were interposed between them was evaluated by means of a testing apparatus. Denture adhesives increase the adhesion of resin samples to the glass surface. Fixon powder showed the highest resistance to dislodgement. The paste forms were found to be more retentive. Denture adhesives when used in combination with synthetic saliva showed the maximum value.

Tree bark is an important natural polymer for sound absorption. The main components in the bark of different tree species are polymers with high molecular weight such as cellulose, hemicellulose, and lignin. The aim of this study is to determine the noise reduction coefficient (NRC), lignin, alcohol-benzene solubility (ABS), carbon (C), and nitrogen (N) contents in samples taken from the bark of different tree species-black locust (Robinia pseudoacacia), narrow-leaved ash (Fraxinus angustifolia), stone pine (Pinus pinea), silver lime (Tilia tomentosa), sweet chestnut (Castanea sativa), sessile oak (Quercus petraea), and maritime pine (Pinus pinaster) and to investigate the relationship between these chemical properties and sound absorption measurements.

Background: The simplicity of synthesis methods has facilitated the illegal manufacture of various fentanyl analogs, leading to numerous fatal overdoses worldwide, particularly in North America. Fentanyl analogs with similar structures are difficult to distinguish due to their fragmentation patterns, making separation using chromatography essential. Additionally, because fentanyl analogs are lethal even in trace amounts, they are easily smuggled, and commonly used fentanyl test strips often fail to detect them due to their low sensitivity.

Malt protein Z (PZ), the main albumin in malt endosperm, exhibits trypsin inhibitory activity and has the ability to bind fat-soluble active molecules. However, its potential utilization as a food ingredient necessitates an evaluation of its allergenicity. Lycopene has many functional activities, such as antioxidant and treatment or alleviation of various diseases, but its tendency to degrade easily hinders its effective utilization.

JNK3, a brain-specific stress-activated protein kinase, plays a critical role in Alzheimer's disease pathogenesis through phosphorylation of Tau and APP. This study aimed to develop selective JNK3 inhibitors based on a pyrazole scaffold, focusing on (E)-1-(2-aminopyrimidin-4-yl)-4-styryl-1H-pyrazole-3-carboxamide derivatives. Through systematic structural modifications and extensive SAR analysis, we identified compounds 24a and 26a as highly potent JNK3 inhibitors, with IC values of 12 and 19 nM, respectively.
