“…The non-significant associations between average HDL and average own or partner future expectations may be because HDL is mainly a product of metabolic cascades that are strongly governed by genetics (Vitali, Khetarpal, & Rader, 2017) and health behaviours (Vincent, Allen, Palacios, Haber, & Maki, 2019). Therefore, the direct contribution of future expectations may be rather small, especially in older age when metabolic problems increase (Yu, Yuan, Yang, & Qi, 2019).…”

Objective. Studies have demonstrated the importance of optimism in predicting perceived general health. However, the handful of studies focusing on cardiovascular biomarkers show inconsistent effects. Additionally, no study examined whether spousal levels of optimism and pessimism affect an individual's biological markers of cardiovascular health. Thus, our objectives were to examine whether partners' optimism and pessimism affect individual biological markers, differentiating between between-dyad associations and within-dyad predictive processes. Methods. Three waves of the Health and Retirement Study collected in 2006, 2010, and 2014 were used to test actor and partner effects of optimism and pessimism on C-reactive protein (CRP) and high-density lipoprotein. Multilevel longitudinal actor-partner models were used to examine the contribution of a partner's optimism and pessimism to each biomarker, adjusting for respondent's age, sex, depression, body mass index, daily activity levels, and a summary score of respondent's doctor-diagnosed chronic conditions. Results. Partners' pessimism and optimism levels were moderately associated. Results for within-person effects were all non-significant, both within and across waves. Associations at the between-person level were also non-significant, with the exception of a positive association between husbands' pessimism and their own CRP, and husbands' optimism and their wives' CRP. Conclusions. Results suggest that optimism and pessimism may not play a pertinent role in within variability of biomarkers of cardiovascular diseases and have a minor role in predicting to between-person variability of biomarkers of cardiovascular diseases.

“…In contrast, Pearson (2015) found higher adiponectin concentrations in colts compared with stallions, with no significant difference (P> 0.05). As animals age, adipose tissue undergoes hypertrophy, resulting in increased adiponectin concentration in the blood and increased insulin sensitivity in adipose tissue (Cawthorn et al 2012;Yu et al 2019). In comparison, Cnop et al (2003) and Ayina et al (2016) report that adiponectin concentration changes are determined by adipose tissue insulin resistance factors, intra-abdominal fat, and lipoprotein profile.…”

Abstract. Hafizuddin, Karja NWK, Praharani L, Setiadi MA. 2021. Breed and age effects on concentration of adiponectin and reproductive performance in Anglo Nubian, Etawah grade and its crossbred bucks. Biodiversitas 22: 1112-1119. The purpose of this study was to evaluate the effect of differences in breed and age on reproductive performance and adiponectin and testosterone production in Anglo Nubian, Etawah grade, and crossbred (Anpera) bucks. A total of 12 bucks with four individuals of each breed were used. This study collected five data points from each buck regarding adiponectin, testosterone, and reproductive performance (libido and semen characteristics). Data were analyzed with factorial analysis of variance and Duncan's test. The result shows that adiponectin concentration between breeds was significantly different (P <0.01). There were also significant differences (P<0.05) in adiponectin concentrations based on buck age. There were also significant interactions with adiponectin concentrations (P <0.01). Furthermore, testosterone concentrations showed significant differences based on breed (P <0.05) and age (P <0.05). There were also significant age-breed interactions affecting testosterone concentrations (P <0.01). Libido and semen characteristics had no significant differences based on breed and age group, and no significant age-breed interactions (P> 0.05). The heterosis effect on adiponectin concentration (48.05%), testosterone concentration (27.68%), libido (-0.61%), semen volume (-1.93%), sperm motility (0.49%), sperm normal morphology (0.18%), and sperm concentration (0.00%) was measured. In conclusion, there is a significant effect of breed, age, and age-breed interactions on the concentration of adiponectin and testosterone in bucks, and both of these variables have a high heterosis effect on crossbred bucks.

“…As stated by Heinz et al [25], the older the bulls, the higher the adiponectin concentration. In other words, as an animal grows older, adipose tissue is more prone to hypertrophy which leads to an increase in both adiponectin concentrations in the blood and insulin sensitivity within the tissue [26]. Increases and decreases in concentrations of adiponectin depend on adipose tissue insulin resistance factors, intra-abdominal fat, and the lipoprotein profile [27].…”

Background and Aim: Capacity for sperm production is affected by age, which is related to the morphology of sperm abnormalities and can affect fertility. The aim of this study was to evaluate the relationship between age and concentrations of testosterone and adiponectin with sperm abnormalities in Simmental bulls. Materials and Methods: The study used 11 bulls, separated into three groups. The first group consisted of five bulls aged 4-5 years, and the second and third groups each consisted of three bulls, aged 6-7 and 8-10 years, respectively. The average sperm motility of the animals ranged from 57.66±2.60% to 70.17±0.22%. Blood samples were obtained from the coccygeal region of the animals. Testosterone and adiponectin analysis was performed using the enzyme-linked immunosorbent assay method. Sperm morphology was evaluated using carbol fuchsin-eosin staining according to the Williams method. Finally, correlations between testosterone and adiponectin concentrations, age, and sperm abnormalities were analyzed using Pearson's correlation analysis. Results: The findings revealed a significant correlation (p<0.01) between the concentrations of testosterone and adiponectin (–0.538), age (–0.588), and abnormal sperm morphology (–0.912). Moreover, they revealed that the concentration of testosterone in the bulls aged 8-10 years was lower, at 21.89±4.56 ng/mL, compared to that in the bulls aged 4-5 years, at 36.15±1.29 ng/mL, and 6-7 years, at 35.16±5.39 ng/mL. The findings also revealed a positive correlation between adiponectin concentration and age (0.529) and sperm abnormalities (0.506). The increase in testosterone concentration was inversely related to the adiponectin concentration (–0.538). Moreover, the mean amount of abnormal sperm increased with increasing age: 3.82±0.33% in the group aged 4-5 years, and 4.40±0.72% and 10.20±1.97% in the groups aged 6-7 years and 8-10 years, respectively. Conclusion: The study data indicate that there is a decrease in testosterone concentration, a high adiponectin concentration, and an increase in abnormal sperm with increasing age in bulls.
