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.

It is already well established that the percentage of normal sperm and specific sperm abnormalities has diagnostic value in vivo. The spermocytogram is an important part of the analysis of human semen, this kind of analysis, simple at first sight, brings real difficulties because the results from one laboratory to another are very relatively reliable. When analyzing abnormal sperm morphology, the observer has to estimate the respective size of the different spermatozoa or their components, the length of all the spermatozoa (too small or too big) and to identify the shape (sperm with a coiled flagellum, or no flagellum as an example). The objective of our work is first of all to make a comparative study of the results of the morphological evaluation of 50 semen samples between the manual technique versus the automated one (SCA) in order to find a possible correlation between these two techniques. According to the analytical stage of the manual and automatic results, the two latter led us to obtain significantly different percentages.

Abstract Study question Are circulating profiles of metabolic-related hormones also associated with the missed abortion (MA) in humans? Summary answer Serum levels of fatty acid-binding protein–4 (FABP4) and fibroblast growth factor 21 (FGF21) are positively associated with MA. What is known already A cluster of endocrine hormones, including FABP4, FGF21, adiponectin, lipocalin–2 (LCN2), exhibit pleiotropic effects on regulating systematic metabolism. Serum levels of them are associated with gestational obesity and diabetes and affect pregnancy outcomes, however, the relationship between their circulating profiles and MA is under-investigated. Study design, size, duration 78 patients with MA and 86 healthy pregnant subjects matching on maternal age and body mass index (BMI) were nested from a prospective cohort in the Chinese population. Participants/materials, setting, methods Fasting serum samples from all participants were collected to test their serum levels of FGF21, FABP4, adiponectin, and LCN2 by enzyme-linked immunosorbent assay method (ELISA). Main results and the role of chance There were no significant differences in circulating profiles of adiponectin and LCN2 between MA patients and healthy pregnant subjects. By contrast, circulating levels of FGF21 and FABP4 were significantly and independently elevated in patients with MA relative to control cases even after adjusting confounding factors (for FGF21: MA: 28.96 ± 2.17 ng/ml; HP: 19.18 ± 1.12 ng/ml, P &lt; 0.001, for FABP4: MA: 152.50 ± 9.31 pg/ml; HP: 90.86 ± 4.14 pg/ml, P &lt; 0.001). Linear regression analysis showed, FGF21 raised every 10 pg/ml contributed to a 24% (95% CI: 15% - 34%) increase in the risk of MA, whereas the OR of FABP4 for the risk of MA was 1.052 (95% CI: 1.022 –1.088). Furthermore, using serum FGF21 level or FABP4 levels discriminated MA from healthy controls with an area under the operating characteristic’s curve (AUROC) of 0.81 (95% CI 0.76–0.92) and 0.70 (95% CI 0.62 - 0.78), respectively. Limitations, reasons for caution The study is limited by the sample size. In addition, our results were based-on Chinese population, whether it could be observed in other ethics group remain to be investigated. Meanwhile, the cause-effect relationship between increased serum FGF21 level and MA remains to be explored. Wider implications of the findings: Our data would suggest that serum levels of FGF21 and FABP4 are associated with MA. Moreover, circulating FGF21 levels may serve as a potential diagnostic biomarker for the recognition of M. Trial registration number IRB Ref. No.: KY201913

The objective of this study was to determine the correlation between spermatozoa morphometry and testosterone concentration in the epididymal caput, corpus, and cauda of aceh cattle. The epididymal sperm swab slides were stained using Williams's staining to examined the morphology and morphometry of spermatozoa whereas the level of testosterone from epididymal caput, corpus, and cauda extract was measured using enzyme-linked immunosorbent assay (ELISA). The data of sperm morphology were presented descriptively whereas the data of sperm morphometry and testosterone concentration were analyzed using one way ANOVA. Pearson correlation test was conducted to know the correlation between the total length of spermatozoa (TLS) and testosterone concentration in three parts of epididymis. The result showed that the sperm morphology in caput, corpus, and cauda of epididymis was not different statistically. The TLS of aceh cattle at caput, corpus, and cauda epididymis were 69,70±0,8 µm, 70,90±0.39 µm, and 72,98±0.74 µm respectively and statistically different (p<0.05). In addition, the concentration of testosterone in caput, corpus, and cauda epididymis were 9,92±3,76 ng/g, 16.96±13,22 ng/g, and 15,63±11.80 ng/g respectively and also not different among three parts of epididymis (p>0.05). The positive correlation (r= 0.413, p= 0.416) was found between TLS and testosterone concentration at caput whereas in corpus and cauda those correlation were negative and not different (corpus: r= -0.638, p= 0.172 and cauda: r= -0.719, p= 0,108). In conclusion, the longest-sized spermatozoa found in the cauda epididymis are mature spermatozoa where the maturation process optimally takes place in caput epididymis. Testosterone found in the epididymis of aceh cow can be used as an alternative source of testosterone.

Purpose To confirm the relationship between plasma osteopontin (OPN) levels and treatment outcomes in head and neck squamous cell carcinoma (HNSCC) patients in an expanded study. Patients and Methods One hundred forty patients with newly diagnosed HNSCC were enrolled onto this study, 54 previously reported and 86 new patients. Pretreatment plasma OPN levels were assessed in all patients by an enzyme-linked immunosorbent assay method. OPN levels were correlated to treatment outcomes in the new group of patients. Detailed analyses were also performed on the relationship between OPN and tumor control rate, event-free survival (EFS), and postrelapse survival for the entire group. Results Using a previously defined cut off point of 450 ng/mL, there was a significant correlation between OPN and freedom-from-relapse (P = .047), overall survival (P = .019), and EFS (P = .023) in the new, independent patient cohort (n = 86). Sequence of event analyses using the entire group (N = 140) revealed that OPN was an independent prognostic factor for initial tumor control, EFS in those who have achieved tumor control, and postrelapse survival. Conclusion In this expanded study, we were able to replicate the prognostic significance of OPN using a predefined cut off point in an independent patient group and demonstrated that plasma OPN is an independent prognostic marker for HNSCC.

This study was conducted to examine testosterone concentrations its relationship with the scrotal circumference and physical characteristics of semen in aceh bulls. Semen samples were collected weekly from jugular vein of three aceh bulls aged 4-5 years old for 10 weeks. Testosterone concentration was measured by enzyme-linked immunosorbent assay (ELISA) method. Semens were collected by using artificial vagina and evaluated for physical characteristics namely ejaculatory volume, pH, and sperm motility, concentration, and abnormalities. Data were analyzed using correlation-regresion test. Testosterone concentrations showed a positive correlation with scrotal circumference (r = 0.799), number of sperm (r = 0.703), sperm motility (r = 0.857) and sperm abnormalities (r = -0,877). No correlation, however, was found between testosterone concentrations with semen volume (r = 0.038) and pH (r = 0.418). It can be concluded that testosterone concentrations correlated positively with scrotal circumference, numbers of sperm, sperm of motility and sperm of abnormality.

Atrial fibrillation (AF) is prevalent in nearly 27% of patients with stage 5 chronic kidney disease on hemodialysis (CKD5-HD), suggesting a strong association between these 2 pathologies. It is hypothesized that the relationship between these 2 diseases may be mediated by inflammation. Angiopoietin-2 (Ang-2), a pro-inflammatory biomarker of endothelial instability, inflammation, and vascular remodeling, is elevated in CKD5-HD and AF, yet has not been evaluated in patients with concomitant AF and CKD5-HD. The aim of this study is to analyze circulating levels of inflammatory and thrombotic biomarkers in patients with concomitant AF and CKD5-HD. Plasma levels of Ang-2 were measured via sandwich enzyme-linked immunosorbent assay method in CKD5-HD patients (n = 96), patients with AF (n = 38), and controls (n = 50). Angiopoietin-2 was markedly elevated in CKD5-HD with comorbid AF as compared to CKD5-HD alone, and AF alone, respectively (13.05 ± 1.56 vs 9.57 ± 0.71 ng/mL; P = .00169; vs 2.48 ± 0.57 ng/mL; P < .0001). The results of this study suggest an additive effect of Ang-2 with coexistence of AF and CKD5-HD, which may be useful in the detection of AF within this patient population.

Summary Pesticides are one of the most potent environmental contaminants, which accumulate in biotic and abiotic components of ecosystems. Acetamiprid (Acm), a neonicotinoid insecticide, and Propineb (Pro), a dithiocarbamate fungicide, are widely used to control sucking insects and fungal infections on crops, respectively. The present study was undertaken to investigate the genotoxic effects of these compounds, individually and in mixtures, in mouse germ cells by using the sperm morphology assay. Mice were injected intraperitoneally with 0.625, 1.25, and 2.50 μg mL-1 of Acm, 12.5, 25, and 50 μg mL-1 of Pro, and their mixture at the same concentrations over 24 and 48 h. Acm did not significantly increase the percentage of abnormal sperm at any concentration. The frequency of abnormal sperm significantly increased after 24 and 48 h of exposure to 50 μg mL-1 of Pro. The mixtures of 2.50 μg mL-1 of Acm and 50 μg mL-1 of Pro induced sperm abnormalities antagonistically both after 24 and 48 h of exposure. Results suggest that Acm was non-genotoxic for mouse germ cells, while Pro may have been a germ cell mutagen due to the observed increase in the frequency of sperm abnormalities. However, to gain better insight into the mutagenicity and DNA damaging potential of both of these pesticides, further studies at molecular level should be done.

SummaryA relapsing clinical syndrome of skin lesions and disseminated intravascular coagulation (DIC) that showed remission with the infusion of fresh frozen plasma is described in a newborn infant with homozygous deficiency of protein C antigen.This patient presented since birth a recurrent clinical picture of DIC and ecchymotic skin lesions that resembled typical ecchymosis except for the fact that they showed immediate improvement with the administration of fresh frozen plasma. Using an enzyme linked immunosorbent assay method, the determination of protein C antigen levels in the patient, without ingestion of coumarin drugs, showed very low values (<1%).No other deficiencies in the vitamin-K-dependent factors or in anti thrombin III, antiplasmin, and plasminogen were found. Seven relatives of the infant had heterozygous deficiency in protein C antigen (values between 40-55%), without clinical history of venous thrombosis. The pedigree analysis of this family suggests an autosomal recessive pattern of inheritance for the clinical phenotype, although an autosomal dominant pattern has been postulated until now in other reported families.We conclude that our patient has a homozygous deficiency in protein C and this homozygous state may be compatible with survival beyond the neonatal period.

Background: MicroRNAs (miRNA) are known to play a key role in the etiology and treatment of epilepsy through controlling the expression of gene. However, miR-125a-5p in the epilepsy is little known. Epilepsy in rat models was induced by Pentylenetetrazol (PTZ) and miR- 125a-5p profiles in the hippocampus were investigated in our experiment. Also, the relationship between miR-125a-5p and calmodulin-dependent protein kinase IV (CAMK4) was identified and the related mechanism was also illustrated. Methods: The miR-125a-5p mRNA expression levels were evaluated by quantitative real time polymerase chain reaction (qRT-PCR). Western Blot (WB) was used to analyze the CAMK4 protein expression levels. Seizure score, latency and duration were determined based on a Racine scale. The enzyme-linked immunosorbent assay (ELISA) was used to analyze the inflammatory factor expression. The relationship between miR-125a-5p and CAMK4 was detected through dual luciferase assay. Results: Downregulation of miR-125a-5p was observed in the hippocampus of PTZ-induced epilepsy rats. The overexpression of miR-125a-5p attenuated seizure and decreased inflammatory factor level in the hippocampus of PTZ-induced rats. The miR-125a-5p alleviated epileptic seizure and inflammation in PTZ-induced rats by suppressing its target gene, CAMK4. Conclusion: miR-125a-5p may represent a novel therapeutic treatment for PTZ-induced epilepsy by preventing the activation of CAMK4.

Abstract Background Elevated angiopoietin-2 (Angpt-2) concentrations are associated with worse overall neurocognitive function in severe malaria survivors, but the specific domains affected have not been elucidated. Methods Ugandan children with severe malaria underwent neurocognitive evaluation a week after hospital discharge and at 6, 12 and 24 months follow-up. The relationship between Angpt-2 concentrations and age-adjusted, cognitive sub-scale z-scores over time were evaluated using linear mixed effects models, adjusting for disease severity (coma, acute kidney injury, number of seizures in hospital) and sociodemographic factors (age, gender, height-for-age z-score, socio-economic status, enrichment in the home environment, parental education, and any preschool education of the child). The Mullen Scales of Early Learning was used in children < 5 years and the Kaufman Assessment Battery for Children 2nd edition was used in children ≥ 5 years of age. Angpt-2 levels were measured on admission plasma samples by enzyme-linked immunosorbent assay. Adjustment for multiple comparisons was conducted using the Benjamini–Hochberg Procedure of False Discovery Rate. Results Increased admission Angpt-2 concentration was associated with worse outcomes in all domains (fine and gross motor, visual reception, receptive and expressive language) in children < 5 years of age at the time of severe malaria episode, and worse simultaneous processing and learning in children < 5 years of age at the time of severe malaria who were tested when ≥ 5 years of age. No association was seen between Angpt-2 levels and cognitive outcomes in children ≥ 5 years at the time of severe malaria episode, but numbers of children and testing time points were lower for children ≥ 5 years at the time of severe malaria episode. Conclusion Elevated Angpt-2 concentration in children with severe malaria is associated with worse outcomes in multiple neurocognitive domains. The relationship between Angpt-2 and worse cognition is evident in children < 5 years of age at the time of severe malaria presentation and in selected domains in older years.
