An investigation of relationships between body compassion, social physique anxiety and physical appearance perfectionism in young people from Iran.

BACKGROUND: Previous studies have shown that physical appearance perfectionism could play an important role in social physique anxiety; however, the moderating role of body compassion has not been studied. The current study aims to explore the moderating role of body compassion in the relationship between physical appearance perfectionism and social physique anxiety in undergraduate students. METHODS: A sample of 418 undergraduates (n = 418; 217 female and 201 males) from three universities in Tehran, Iran completed online questionnaires measuring physical appearance perfectionism, body compassion and social physique anxiety. RESULTS: The results of structural equation modeling showed that physical appearance perfectionism (ß = 0.68, p < 0.001) positively predicted the social physique anxiety and body compassion negatively predicted (ß = - .56, p < 0.001) the social physique anxiety in undergraduate students. A multi-group analysis showed that body compassion acted as a moderator between physical appearance perfectionism and social physique anxiety. CONCLUSIONS: The results suggested that individuals with greater levels of physical appearance perfectionism are more likely to experience social physique anxiety. Also, the results suggested that individuals who were at a high level of the body-compassion group experienced lower levels of social physical anxiety if they also had high levels of physical appearance perfectionism. Therefore, body-compassion acted as a protective role in the relationship between physical appearance perfectionism and social physique anxiety.

Anxiety over one's physical appearance in social situations is known as social physique anxiety. One of the variables that plays an important role social physique anxiety is physical appearance perfectionism. General perfectionism, body dissatisfaction, the symptoms of eating disorders and muscle dysmorphia and obsessive exercise are all linked to physical appearance perfectionism. The results of the current study showed individuals with high levels of physical appearance perfectionism are more likely to experience social physique anxiety. In the current study, we tested the moderating role of self-compassion in the relationship between physical appearance perfectionism and social physique anxiety. Body compassion is characterized by diffusion, common humanity, and acceptance of one's own body as opposed to being judgmental, critical, isolated, and over-identifying with unpleasant experiences and emotions. The findings showed in the group with high body- compassion, the relationship between physical appearance perfectionism and social physique anxiety was not significant, which means that body-compassion played a buffering role in this relationship.

The association between prenatal exposure to polycyclic aromatic hydrocarbons and childhood intelligence: a systematic review of observational studies.

Exposure to polycyclic aromatic hydrocarbons (PAHs) during pregnancy has been associated with many adverse child health. However, the evidence on such associations with child brain development was not reviewed systemically. Therefore, in this study, we systemically reviewed the observational studies on prenatal exposure to PAHs and childhood intelligence quotient (IQ). The Meta-analyses Of Observational Studies in Epidemiology (MOOSE) guidelines were applied to perform this review. We systematically searched Scopus, PubMed, and Web of Science for all relevant articles published in English until 15 October 2022. The quality of retrieved studies was evaluated based on the Gascon et al. method. We retrieved a total of 351 citations through the initial search, of which an overall of six articles ([Formula: see text] participants) were included in our final review. The quality assessment indicated that four studies had excellent and two studies had good quality. Three reviewed studies reported a significant negative association between prenatal exposure to PAHs and children's IQ. One study reported that exposure to PAHs combined with material hardship was associated with lower child IQ and one study indicated lower child IQ through lower LINE1 DNA methylation-related maternal exposure to PAHs. However, another study did not observe a significant association between prenatal PAH exposure and child IQ. Overall, our review indicated that exposure to PAHs during pregnancy has an adverse impact on childhood IQ.

Moderating Role of Self-Compassion in the Relationships Between the Three Forms of Perfectionism with Anger, Aggression, and Hostility.

The prevalence of aggression in adolescents is on the rise, and it could be a serious public health concern. Studies have found positive relationships between perfectionism with anger, aggression, and hostility. However, the moderating role of self-compassion in the links between perfectionism with anger, aggression, and hostility has not been studied. To better understand the relationships between the three forms of perfectionism with anger, aggression, and hostility, this study aimed to explore the moderating role of self-compassion. Participants were 380 undergraduates selected using a multi-stage cluster sampling technique from three universities in Iran. Participants completed the Self-Compassion Scale, the Multidimensional Perfectionism Scale, and the Aggression Questionnaire Scale. The results from structural equation modelling analysis showed that other-oriented perfectionism and socially prescribed perfectionism positively predicted anger, aggression, and hostility. The results showed that self-oriented perfectionism significantly and positively predicted anger and hostility; but there were no observed statistically significant relationships of self-oriented perfectionism with verbal aggression and physical aggression. The findings showed that self-compassion played a moderating role in the relationships between other-oriented perfectionism and socially prescribed perfectionism with anger, aggression, and hostility; however, it did not play a moderating effect on self-oriented perfectionism with anger, aggression, and hostility. The findings provide a deeper understanding of the moderating role of self-compassion in the links between other-oriented perfectionism and socially prescribed perfectionism with anger, aggression, and hostility among undergraduates. The findings of this study could be applicable for psychologists and counselors who deal with aggressive behavior, anger, and hostility in undergraduate students to assess the three forms of perfectionism and self-compassion.

Optical and Electrochemical Aptasensors Developed for the Detection of Alpha-Fetoprotein.

Early diagnosis of hepatocellular carcinoma (HCC), a leading cause of cancer mortality, is decisive for successful treatment of this type of cancer and increasing the patients' survival rate. Alpha-fetoprotein (AFP) is a glycoprotein that has been currently employed as a potential serological biomarker for determination of HCC and several other cancers. Achieving highly sensitive and specific detection of this biomarker is an effective strategy to inhibit developing issues caused by the cancer. Though, traditional procedures cannot meet the requirements due to the technical drawbacks. Recently, growing number of aptamer-based biosensors (aptasensors) attracted important attention as superior diagnostic tools because of their unique properties such as high stability, target versatility and remarkable affinity and selectivity. Nanomaterials, which broadly employed in the structure of these aptasensors, can considerably enhance the detection limit and sensitivity of analytes determination. Therefore, this review selectively investigated the recent progresses in several different optical and electrochemical aptasensors and nano-aptasensors designed for AFP assay.

Survey of ground beetles inhabiting agricultural crops in south-east Kazakhstan.

Ground beetles (Carabid beetles) may be found in virtually all of the world's habitats. They are one of the three most diverse families of extant beetles, with 34,275 species documented, and they serve as vital ecological markers in all environments. Edaphic living beetles catch and eat a wide variety of arthropods that live in the soil. In the case of weeds, most of the ground beetles eat their seeds and help regulate their populations. The findings of a field study in agrocenoses in South-East Kazakhstan from 2019 to 2020 are presented in this article. Twenty-seven ground beetle species from 9 genera were discovered as a consequence of the study. 670 soil traps yielded a total of 1012 beetles. Polytopic mesophilic beetles provide the foundation of the agrocenoses fauna. Hygrophils, mesophiles, and eurybionts are among the beetles found in irrigated areas, as are mixed and herbivorous species. The Carabidae family of beetles is the most numerous in fields and steppe settings. As a result, mixed-diet beetles can be found depending on the habitat and air temperature. The species of beetles in all fields in the investigation area are in accordance with the insects' complex. During the growth season, the diet of beetles shifts: predatory beetles take precedence initially, followed by mixed-diet beetles.

Autophagy-related chemoradiotherapy sensitivity in non-small cell lung cancer (NSCLC).

Lung cancer is one of the leading causes of tumor-related mortalities worldwide. NSCLC is the most common type of lung cancer. In recent years, advancements in chemoradiotherapy and immunotherapy have led to unprecedented survival benefits in some patients. However, conventional therapies such as radiation and chemotherapy are not effective in all patients due to the chemo or radioresistance mechanisms; as a result, there is an urgent need for understanding the resistant mechanism. Given that malignancies are caused by changes in cell homeostasis, autophagy may help chemo/radiosensitization by removing damaged compartments and enhancing tumor clearance. Autophagy, on the other hand, may help cancer cells survive by increasing the breakdown of cell cycle regulators. Considering these inconsistencies, this study aimed to overview the intricacy of autophagy in response to chemoradiotherapy in lung cancer.

Effects of Dietary Pectin and Lactobacillus salivarius ATCC 11741 on Growth Performance, Immunocompetence, Gut Microbiota, Antioxidant Capacity, and Disease Resistance in Narrow-Clawed Crayfish, Postantacus leptodactylus.

The present study was conducted to clarify the effects of Lactobacillus salivarius (LS) ATCC 11741 and pectin (PE) on growth performance, digestive enzymes activity, gut microbiota composition, immune parameters, antioxidant defense as well as disease resistance against Aeromonas hydrophila in narrow-clawed crayfish, Postantacus leptodactylus. During 18 weeks trial feeding, 525 narrow-clawed crayfish juvenile (8.07 ± 0.1 g) fed with seven experimental diets including control (basal diet), LS1 (1 × 107 CFU/g), LS2 (1 × 109 CFU/g), PE1 (5 g/kg), PE2 (10 g/kg), LS1PE1 (1 × 107 CFU/g +5 g/kg), and LS2PE2 (1 × 109 CFU/g +10 g/kg). After 18 weeks, growth parameters (final weight, weight gain, and specific growth rate) and feed conversion rate were significantly improved in all treatments (P < 0.05). Besides, diets incorporated with LS1PE1 and LS2PE2 significantly increased the activity of amylase and protease enzymes compared to LS1, LS2, and control groups (P < 0.05). Microbiological analyses revealed that the total heterotrophic bacteria count (TVC) and lactic acid bacteria (LAB) of narrow-clawed crayfish fed diets containing LS1, LS2, LS1PE1, and LS2PE2 were higher than control group. The highest total haemocyte count (THC), large-granular (LGC) and semigranular cells (SGC) count, and hyaline count (HC) was obtained in LS1PE1 (P < 0.05). Similarly, higher immunity activity (lysozyme (LYZ), phenoloxidase (PO), nitroxidesynthetase (NOs), and alkaline phosphatase (AKP)) observed in the LS1PE1 treatment compared to the control group (P < 0.05). The glutathione peroxidase (GPx) and superoxide dismutase (SOD) activity remarkably enhanced in LS1PE1 and LS2PE2, while malondialdehyde (MDA) content reduced in these two treatments. In addition, specimens belonging to LS1, LS2, PE2, LS1PE1, and LS2PE2 groups presented higher resistance against A. hydrophila compared to the control group. In conclusion, feeding narrow-clawed crayfish with synbiotic had higher efficiency on growth parameters, immunocompetence, and disease resistance compared to single consumption of prebiotics and probiotics.
