The HPG axis can be suppressed by the activation of the hypothalamo-pituitary-adrenal (HPA) axis. The physiological role of kisspeptin in the interaction of the HPG axis and the HPA axis is not fully understood yet. The purpose of the current study was to investigate the possible effects of peripheral injection (intraperitoneally) of kisspeptin on HPG axis and HPA axis activity as well. Adult male Wistar rats were randomly divided into seven groups as sham (control), kisspeptin (10 nmol), p234 (10 nmol), kisspeptin + p234, kisspeptin + antalarmin (10 mg/kg), kisspeptin + astressin2b (100 μg/kg), and kisspeptin + atosiban (0.250 mg/kg) (n = 10 each group). At the end of the experiment, the hypothalamus, pituitary gland, and serum samples of the rats were collected. Serum follicle-stimulating hormone and luteinizing hormone levels of the kisspeptin, kisspeptin + antalarmin and kisspeptin + astressin2b groups were significantly higher than the control group. Serum testosterone levels were significantly higher in the kisspeptin, kisspeptin + antalarmin, kisspeptin + astressin2b, and kisspeptin + atosiban groups that compared to the control group. There was no a significant difference in corticotropic releasing hormone immunoreactivity in the paraventricular nucleus of the hypothalamus, serum adrenocorticotropic hormone and corticosterone concentrations among all groups. Moreover, no significant difference was found in the concentration of pituitary oxytocin. Our results suggest that peripheral kisspeptin injection induces an activation in the HPG axis, but not in the HPA axis in male rats.","PeriodicalId":8853,"journal":{"name":"Biologia futura","volume":" ","pages":"477-486"},"PeriodicalIF":1.8,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142153097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sandalwood grown alone and with five selected hosts (Alternanthera sp., Neem, Shisham, Dek and Agarwood) on the basis of prior study under water deficit, salinity stress and combined water deficit and salinity stress. Sandalwood plants were harvested after 180 days of imposing stress treatments. Morphological traits (plant height, collar diameter, shoot fresh and dry biomass) showed significant reduction under water deficit and salinity stress, which were further aggravated under combined water deficit and salinity stress. Studied plant water traits, ionic balance and gas exchange attributes were also reduced by these stresses. While among studied host, Shisham and Dek identified as the best host species under water deficit, salinity and interactive stress by maintaining ion homeostasis, osmotic adjustments and plant water regulation. Results depicted that sandalwood plants cultivated alone were not able to survive under salinity and combined stress conditions and showed poor growth under water deficit and control conditions. Different indices were also calculated based on morpho-physiological and ionic traits and also indicated that sandalwood grown with Dalbergia sissoo and Melia dubia showed higher drought, salt and stress tolerance potential, which made sandalwood adaptable under these stresses. Therefore, the present study signifies the importance of host especially D. sissoo and M. dubia which might be excellent long-term host species for sandalwood cultivation under sub-tropical conditions to thrive under changing environments.","PeriodicalId":8853,"journal":{"name":"Biologia futura","volume":" ","pages":"497-506"},"PeriodicalIF":1.8,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140911789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the psychological meaning of a left or right-sided EDA dominance is still not clear. We explored EDA lateral asymmetry as a psychophysiological marker of optimistic and pessimistic attributional style regarding success and failure in a darts competition. Bilateral EDA pattern of 230 throws of a competing pair was measured by Obimon EDA including accelerometer measurements of movements. First, we confirmed that lateral asymmetry can be measured reliably based on EDA data from both wrists. Second, we assessed attributional styles related to lateral asymmetry based on 80 individual throws. We recorded participants' expectations regarding their upcoming performance, and their attribution of success and failure based on Seligman's definition as optimist (internal cause attributed to success, or external cause ascribed to failure) or pessimist. The ratio of optimist and pessimist attributions was significantly different for throws with right or left-sided EDA dominance (p = 0.001). Optimistic attribution characterized 84% of right dominant, while pessimist 63% of left-dominant EDA during throws. We replicated these findings on 50 throws from 10 more individuals (p = 0.034). All individuals were right-handed. We conclude that wrist EDA can be reliably measured during physical movements, such as in a darts game. Lateral EDA asymmetry is a consistent psychophysiological marker of the attitude toward success and failure in a competitive setting, suggesting that lateral asymmetry of emotional arousal may serve as a novel psychophysiological biomarker for attribution style. Results underlie the psychophysiological relevance of bilateral arousal assessment and provide evidence-based verification for the Multiple Arousal Theory.","PeriodicalId":8853,"journal":{"name":"Biologia futura","volume":" ","pages":"379-390"},"PeriodicalIF":1.8,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141074571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the date of flowering in photoperiod sensitive (PPS) rice cultivars is characteristically determined by the day length, especially during the short-day season (September-December), the response of the flower opening time (FOT) to photoperiod remains hitherto unexplored. This paper examines whether day length restrains year-to-year variation in FOT in PPS cultivars. We examined 105 PPS and 173 photoperiod insensitive (PPI) cultivars grown in different years and estimated their year-to-year FOT difference (or FOTD) and the year-to-year difference of sunrise to anthesis duration (or SADD). Wilcoxon signed rank test and bootstrap test were then performed to test whether these descriptors significantly differed between PPS and PPI groups of cultivars. The means of FOTD and SADD were detected to be significantly less in the PPS group than in the PPI group of cultivars, indicating significantly lesser variability of FOT in PPS than in PPI cultivars. This is the first report of a strong restraining influence of photoperiod on FOT variability in PPS cultivars.","PeriodicalId":8853,"journal":{"name":"Biologia futura","volume":" ","pages":"453-458"},"PeriodicalIF":1.8,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140921061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study aimed to examine the chemical characteristics of Hordeum vulgare methanolic and aqueous extracts and assess their antioxidant activity using the DDPH and ORAC. Furthermore, the inhibitory effect of xanthine oxidase was screened. TLC bioautography was employed to determine the polarity of the compounds present in the extracts that exhibited the most potent free radical scavenging activity. Total flavonoid content of the methanolic and aqueous extracts was 0.14 mg QE/g and 0.012 mg QE/g, respectively. The antioxidant activity of the methanolic extract was found to be more potent, with a value of 0.97 ± 0.13 mmol TE/g than the aqueous extract which had no activity. This study presents novel findings on the xanthine inhibitory activity of H. vulgare. The methanolic extract demonstrated moderate inhibition of xanthine oxidase with a value of 23.24%. The results of our study were compared with the phytochemical and pharmacological analysis of Triticum aestivum, and further comparison was made with the data reported in the literature. Inconsistencies were observed in the chemical and pharmacological properties of H. vulgare, which could be a result of using herbal material harvested in different vegetative phases and various methods used for extraction. The findings of our study indicate that the timing of the harvest and extraction method may play crucial role in attaining the optimal phytochemical composition of H. vulgare, hence enhancing its pharmacological activity.","PeriodicalId":8853,"journal":{"name":"Biologia futura","volume":" ","pages":"391-399"},"PeriodicalIF":1.8,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141533522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
