State appearance comparison significantly mediated the effect of TikTok videos on body dissatisfaction and mood, however, there was no moderating effect of trait fit ideal internalisation. These findings highlight the importance of state appearance comparison in relation to viewing fitspiration content on TikTok.
Alzheimer's disease (AD) is the most progressive form of neurodegenerative disease resulting in cognitive and non-cognitive deficits. Aluminum is recognized as a risk factor for the etiology, pathogenesis, and progression of AD. The present study was designed to determine the effects of p-coumaric acid (p-CA), a phenolic compound, on spatial cognitive ability and non-cognitive functions and to identify the role of oxidative stress and inflammation in an AD rat model induced by aluminum chloride (AlCl
).
Both AlCl
(100mg/kg/day; P.O.) and p-CA (100mg/kg/day; P.O.) treatments were given for six consecutive weeks. During the fifth and sixth weeks of the treatment period, the cognitive and non-cognitive functions of the rats were assessed using standard behavioral tests. Additionally, oxidative-antioxidative status, inflammatory markers, and histological changes were evaluated in the cerebral cortex and hippocampal regions of the rats.
The results of this study showed that AlCl
exposure enhanced anxiety-/depression-like behaviors, reduced locomotor/exploratory activities, and impaired spatial learning and memory. These cognitive and non-cognitive disturbances were accompanied by increasing oxidative stress, enhancing inflammatory response, and neuronal loss in the studied brain regions. Interestingly, treatment with p-CA alleviated all the above-mentioned neuropathological changes in the AlCl
-induced AD rat model.
The findings suggest that both anti-oxidative and anti-inflammatory properties of p-CA may be the underlying mechanisms behind its beneficial effect in preventing neuronal loss and improving cognitive and non-cognitive deficits associated with AD.

Circular RNAs (circRNAs) have been identified to play roles in cartilage homeostasis and chondrocyte development, and be associated with osteoarthritis (OA) pathophysiology. Chk2 Inhibitor II in vivo Here, we aimed to investigate the role and mechanism of circ_0022383 on OA progression.
Chondrocytes in functional groups were treated with interleukin (IL)-1β. The levels of genes and proteins were assayed by qRT-PCR and western blotting. Cell proliferation and apoptosis were evaluated by cell counting kit-8 assay, 5-Ethynyl-2'-deoxyuridine (Edu) assay, and flow cytometry, respectively. The inflammation and extracellular matrix (ECM) degeneration were determined by assessing the activity of IL-6, tumor necrosis factor (TNF-α), Aggrecan (ACAN), collagen type II α 1 chain (COL2A1) and ADAMTS5 proteins. The binding between miR-3619-5p and circ_0022383 or silent information regulator 1 (SIRT1) was confirmed by dual-luciferase reporter, RIP and RNA pull-down assays.
Circ_0022383 expression was lower in the cartilages of OA patients and ent for OA prevention.
The use of cyclophosphamide (CP) as a chemotherapeutic agent is limited by its major complication haemorrhagic cystitis (HC). Finding preventive, safe, and efficient treatments for such problems is extensively ongoing.
This research aims to assess the uroprotective effect of pramipexole (PPX) and/or lactoferrin (LF) against CP-induced HC, in addition to shedding light on their possible molecular targets.
Adult male Sprague-Dawley rats were orally administered PPX (3mg/kg) and/or LF (300mg/kg) for seven consecutive days, followed by a single intraperitoneal injection of CP (150mg/kg).
Pretreatment of CP-intoxicated rats with either PPX or LF mitigated oxidative urinary bladder damage via upregulation of the Nrf2/HO-1 signalling pathway, resulting in a significant reduction in bladder MDA and 8-OHdG levels with concomitant elevations in SOD activity and GSH content. Simultaneously, both drugs markedly halted inflammation in bladder tissue through inhibition of the TLR4/NF-κB signalling pathway, followedism underlying this protective effect may involve targeting the crosstalk among Sphk1/S1P/MAPK/NF-κB, TLR-4/NF-κB, and NLRP3/caspase-1/IL-1β signalling pathways and modulating the Nrf2/HO-1 signalling pathway.
The submandibular salivary glands (SMG) represent a suitable model for studying epithelial cell growth and differentiation. Bisphenol A (BPA) is a xenoestrogen, synthesized to produce polymers such as polycarbonates and epoxy resins. There are concerns about the occurrence of BPA in food, water as well as its appearance in human tissues and body fluids. Lycopene (LYC) is a carotenoid compound that exerts antioxidant and anti-inflammatory properties. This work was performed to study possible protective effect of LYC against BPA toxicity in SMG.
40 albino rats were divided into 4 groups; Group I served as controls. Group II rats received LYC (4mg/kg, p.o), Group III rats received BPA (10mg/kg, p.o) and Group IV rats received LYC (4mg/kg, p.o) and BPA (10mg/kg, p.o). All drugs were administered for 45days then under anesthesia, rats were sacrificed. The SMG specimens were taken for histological and biochemical studies.
BPA resulted in a significant rise of malondialdehyde, tumor necrosis factor-α and interleukine-1β. In contrast, the tissue levels of glutathione and PPAR-γ were significantly decreased. BPA activated Wnt/β-catenin pathway evidenced by upregulating WNT3a, β-catenin and c-myc expression. Moreover, SMG of BPA showed degenerative changes that affected the parenchymal and stromal elements of the glands. The immunohistochemical localization of cytokeratin 5,6 and 18 of BPA rats revealed weak immunostaining of the serous secretory cells, myoepithelial cells and ductal cells. Upon treatment with LYC, glutathione and PPAR-γ were restored.
LYC acted as a protective agent against BPA-induced pathological changes in SMG.

A total of 32 sampling sites was chosen in proximity to deciduous (Acer, Castanea, Fagus, Tilia, Platanus, Quercus) and coniferous (Fraxinus, Picea, Pinus, Tsuga) trees. Meadows and creeks were also sampled. The overall taxonomic record comprises 76 species and sub-species. High species numbers of >20 per sample were found in meadows and below Fagus, Tilia, and Quercus trees. The species richness per park ranges from 33 to 46 taxa. Most species belong to the eurybiontic ecological group, although litter-inhabiting and hygrophilic and hydrophilic species were also present. Common species found in more than 50% of all samples (superdominants) belong to the genera Centropyxis, Cyclopyxis, Euglypha, and Trinema. Interestingly, the rare Frenopyxis stierlitzi which inhabits tree hollows was found as a recently described species in a new genus FrenopyxisBobrov&Mazei2020 in the Babelsberg Park. The studied testate amoebae are characterized by a high degree of morphological and morphometric plasticity. Therefore, the study of testate amoebae in urban settings will reveal new insights into their ecology and enhance the definition of morphometric variability for single species.Sex identification of faces without any cultural or conventional sex cue is primarily based on two independent components a) shape or facial structure, and b) surface reflectance (skin texture and color). The present work studied the relative contribution of each component by means of two experiments based on 3D face models created with different degrees of masculinity-femininity within a sex continuum. The first experiment utilized totally artificial faces created ex novo by computer. The second employed face models created from photographs of real people. The results of both experiments were consistent. As expected, when both components were present in a face, sex was correctly classified in almost all the cases. More interestingly, the contribution of the "pure" facial structure to the sex perception (with no surface reflectance) was about 80%, whereas 20% of the total information was provided by the surface reflectance. Furthermore, examination of the psychometric curves suggests that the information provided by surface reflectance contributes to a categorical perception of facial sex, since when it is removed the sex is perceived in a more continuous / less categorical way. On the other hand, our stimuli presented a certain "male" bias, repeatedly found in the literature on facial sex perception.Projecting future air pollution and related health burdens remains challenging because of the complex interactions among future emissions, population, and climate change. In this study, we estimated the premature deaths attributed to ambient fine particulate matter (PM2.5) and ozone (O3) from 2015 to 2100 under four socioeconomic climate scenarios based on an age-stratified assessment method. We found that PM2.5 will decrease in all shared socioeconomic pathway (SSP) scenarios and O3 will decrease in the SSP1-2.6 and SSP2-4.5 scenarios, contributing to a decrease in premature mortality together with the declining total population in China. However, the benefits of a decline in population size and PM2.5 and O3 concentrations over time will be largely offset by population aging, and premature death caused by PM2.5 and O3 will continue to rise till 2060-2080. This impact was greater for the O3-related deaths than those for PM2.5. Our study highlights the importance of future prevention strategies that must jointly improve air quality and susceptibility to aging.
ECIGs differ in their ability to deliver nicotine to the user and, consequently, they may differ in their ability to produce dependence. This study examined individual device characteristics, device type, and user behaviors as predictors of ECIG dependence in a sample of never-smoking ECIG users.
Participants (N=134) completed an online survey that assessed demographics, ECIG use behavior, and ECIG dependence as measured via the Penn State Electronic Nicotine Dependence Index (PSECDI) and E-cigarette Dependence Scale (EDS-4). Participants uploaded a picture of their personal ECIG device/liquid, which was coded by raters to identify product features. Multivariable linear regressions examined device characteristics (e.g., adjustable power, nicotine concentration) and device type (e.g., vape pen, mod, pod, modern disposable) as predictors of dependence controlling for demographics and user behaviors (e.g., ECIG use duration and frequency, other tobacco use).
Longer durations of ECIG use and more use days/week were associated significantly with higher PSECDI (β's=0.91 and 1.90, respectively; p's<0.01) and EDS-4 scores (β's=0.16 and 0.28, respectively; p's<0.01). Higher nicotine concentrations were associated with higher PSECDI scores only (β=0.07, p=.011). Dependence scores did not differ as a function of ECIG device types after controlling for covariates.
ECIG dependence was observed among the never-smoking ECIG users in this sample, regardless of their ECIG device/liquid features. Findings suggest that regulatory efforts aimed at reducing the dependence potential of ECIGs in never smokers should focus on overall nicotine emissions rather than product features.
