st there are no current PROMs that are suitable pain-specific instruments for women with POP or SUI. This knowledge may inform and assist in the development of a new PROM to be implemented into the APFPR.The cellular defense mechanisms against cumulative endo-lysosomal stress remain incompletely understood. Here, we identify Ubr1 as a protein quality control (QC) E3 ubiquitin-ligase that counteracts proteostasis stresses by facilitating endosomal cargo-selective autophagy for lysosomal degradation. Astrocyte regulatory cluster membrane protein MLC1 mutations cause endosomal compartment stress by fusion and enlargement. Partial lysosomal clearance of mutant endosomal MLC1 is accomplished by the endosomal QC ubiquitin ligases, CHIP and Ubr1 via ESCRT-dependent route. As a consequence of the endosomal stress, a supportive QC mechanism, dependent on both Ubr1 and SQSTM1/p62 activities, targets ubiquitinated and arginylated MLC1 mutants for selective endosomal autophagy (endophagy). This QC pathway is also activated for arginylated Ubr1-SQSTM1/p62 autophagy cargoes during cytosolic Ca2+-assault. Conversely, the loss of Ubr1 and/or arginylation elicited endosomal compartment stress. These findings underscore the critical housekeeping role of Ubr1 and arginylation-dependent endophagy/autophagy during endo-lysosomal proteostasis perturbations and suggest a link of Ubr1 to Ca2+ homeostasis and proteins implicated in various diseases including cancers and brain disorders.<br /><br /> Perfluorodecanoic acid (PFDA) is a type of perfluoroalkyl acid (PFAA). PFDA has toxicity similar to dioxin; its effect on the body is not through a single target or a single pathway. However, the mechanism at the global level is still unclear.<br /><br /> We treated mice with PFDA and characterized the global changes in gene expression in the liver using microarray analyses. The enriched KEGG pathways and GO analyses revealed that PFDA greatly affected the immune response, which was different from the response of gastric cells previously studied. As a proof of principle, the expressions of IL-1β and IL-18 were both decreased after PFDA treatment, and qRT-PCR and ELISAs verified the reduction of IL-1β and IL-18 in liver tissues. Mechanistic investigations indicated that PFDA inhibited caspase-1 activation, and decreased the mRNA levels of NLRP1, NLRP3, and NLRC4; thus, suggesting that inflammasome assemblies were suppressed. Further microarray data revealed that cIAP2 and its binding proteins, which are critical for regulating inflammasome assembly, were also repressed by PFDA. In addition, flow cytometry results revealed a significant inhibition of Th1 cell differentiation in the livers of PFDA-treated mice.<br /><br /> The results of this study suggested that one of the main toxic effects of PFDA on livers was the inhibition of immune response.<br /><br />The results of this study suggested that one of the main toxic effects of PFDA on livers was the inhibition of immune response.An important but understudied modality for eavesdropping between predators and prey is olfaction, especially between non-mammalian vertebrate predators and their prey. Here we test three olfactory eavesdropping predictions involving an apex reptilian predator, the sand goanna Varanus gouldii, and several species of its small mammalian prey in arid central Australia 1) small mammals will recognize and avoid the odour of V. gouldii; 2) V. gouldii will be attracted to the odour of small mammals, especially of species that maximize its energetic returns; and 3) small mammals will be less mobile and will show higher burrow fidelity where V. gouldii is absent compared with where it is present. As expected, we found that small mammals recognized and avoided faecal odour of this goanna, feeding less intensively at food patches where the odour of V. gouldii was present than at patches with no odour or a pungency control odour. Varanus gouldii also was attracted to the odour of small mammals in artificial burrows and dug more frequently at burrows containing the odour of species that were energetically profitable than at those of species likely to yield diminishing returns. Our third prediction received mixed support. Rates of movement of three species of small mammals were no different where V. gouldii was present or absent, but burrow fidelity in two of these species increased as expected where V. gouldii had been removed. We conclude that olfaction plays a key role in the dynamic interaction between V. gouldii and its mammalian prey, with the interactants using olfaction to balance their respective costs of foraging and reducing predation risk. We speculate that the risk of predation from this apex reptilian predator drives the highly unusual burrow-shifting behaviour that characterizes many of Australia's small desert mammals.Similar to hemophagocytic lymphohistiocytosis (HLH), some patients with SARS-CoV-2 have cytokine storm. Serum soluble interleukin-2 receptor (sCD25) and soluble CD163 (sCD163) are potential diagnostic biomarkers for HLH that help in guiding its treatment. This study was the first to investigate serum sCD25 and sCD163 levels in SARS-CoV-2. Serum sCD25 and sCD163 were measured by ELISA in 29 patients with SARS-CoV-2, aged between 2 months and 16 years (13 had COVID-19 and 16 had multisystem inflammatory syndrome in children (MIS-C)), in comparison to 30 age- and sex-matched healthy control children and 10 patients with HLH. Levels of these markers were re-measured in 21 patients with SARS-CoV-2 who were followed up 3 months after recovery. Patients with SARS-CoV-2 had significantly higher serum sCD25 and sCD163 than healthy control children (P  less then  0.001). SARS-CoV-2 patients had significantly higher sCD25 than patients with HLH (P  less then  0.05). Serum sCD25 was a good differentiating marker between s can also help in guiding the treatment.

In this study, a total of 604 fecal samples were collected from pet dogs in Xinjiang, China to detect the presence of Cryptosporidium spp. and G. duodenalis by PCR amplification of the small subunit (SSU) rRNA gene. The incidence rate of Cryptosporidium spp. or G. duodenalis was 5.3% (32/604). Among the collection sites, a higher number of Cryptosporidium spp. or G. duodenalis positive dogs were detected in Hotan (9.9%, 21/213) and Shihezi (9.8%, 4/41) were higher than those in Aksu (4.5%, 1/22), Urumqi (2.1%, 4/191), and Korla (1.5%, 2/137). Among the sources, dogs in pet shops (7.4%, 19/256) showed a significantly higher incidence rate than those in pet hospitals (3.0%, 4/134) and pet kennels (2.3%, 5/214). When the data were examined by age, dogs  less then  1 year of age (6.1%, 28/459) were more likely to be infected by Cryptosporidium spp. or G. duodenalis than older (≥ 1 year) dogs (2.8%, 4/145). No significant differences were observed when animals were grouped by sex (5.0%, 14/278 for males; 5.5%, 18/326 for females). Sequence analysis revealed that the Cryptosporidium spp. (n = 10) in dogs were identified as C. canis. The G. duodenalis detected belonged to assemblages A (n = 1), C (n = 14), and D (n = 7). Among the identified 22 G. duodenalis isolates, eight samples were subtyped according to β-giardin (bg) and the results were consistent with the identified assemblages. To our knowledge, this is the first report of Cryptosporidium spp. and G. duodenalis infections in domesticated canines in Xinjiang, China. The C. canis and G. duodenalis assemblage A identified in pet dogs in the present study were previously associated with infections in humans, indicating the potential for zoonotic transmission.To reduce environmental pollution, it is essential to use green processes in dyeing and meet its requirements. Most natural dyes have a low affinity to be used in the dyeing process. To refine this limitation, the mordanting flow is necessary for many dyeing cases. Pumpkin extract as a natural, metal-rich source can be used as a bio-mordant in green dyeing of natural yarns such as wool. Two natural dyes native to Iran, Reseda luteola and madder, were employed in this study. The effectiveness of bio-mordant presence on yarns was evaluated by FTIR-ATR test from mordanted and mordanted-dyed wool samples. The study of K/S (color strength) content of dyed samples showed that increasing the dye concentration increases the amount of K/S. Fastness performance of wool dyed with pumpkin alternated from good to excellent depending on natural dye type and concentration, due to the formation of complex structures.Bioactive compounds refer to secondary metabolites extracted from plants, fungi, microbes, or animals. Besides having pharmacological or toxicological effects on organisms leading to utilization in food and pharmaceutical industries, the discovery of novel properties of such compounds has led to the diversification of their applications, ranging from cosmetics and functionalized biomaterials to bioremediation and alternate fuels. Conventional time-consuming and solvent-intensive methods of extraction are increasingly being replaced by green solvents such as ionic liquids, supercritical fluids, and deep eutectic solvents, as well as non-conventional methods of extraction assisted by microwaves, pulse electric fields, enzymes, ultrasound, or pressure. These methods, along with advances in characterization and optimization strategies, have boosted the commercial viability of extraction especially from agrowastes and organic residues, promoting a sustainable circular economy. Further development of microfluidics, optimization models, nanoencapsulation, and metabolic engineering are expected to overcome certain limitations that restrict the growth of this field, in the context of improving screening, extraction, and economy of processes, as well as retaining biodiversity and enhancing the stability and functionality of such compounds. This review is a compilation of the various extraction and characterization methods employed for bioactive compounds and covers major applications in food, pharmacy, chemicals, energy, and bioremediation. Major limitations and scope of improvement are also discussed.The massive rise in the world's average temperature has created major economic and environmental issues that must be addressed by strict environmental legislation. Carbon pricing is seen as a sustainable instrument capable of assisting in the reduction of negative environmental externalities associated with global carbon emissions. The race-to-the-bottom (RTB) hypothesis describes a competitive environment in which economies sacrifice environmental quality standards to undercut competitors, thus undermining the ecological sustainability objective. The study contributed to the evaluation of the RTB hypothesis by examining the role of emissions cap trading instruments in conjunction with inbound foreign direct investment, economic growth, renewable energy demand, and trade openness in reducing carbon emissions, using aggregated data from high-income countries from 1975 to 2019. The linear and non-linear ARDL estimator is used for empirical analysis. The results show that emissions cap trading lowers carbon emissions in the long run while increasing in the short run.
