We conducted this study to analyze the sperm DNA fragmentation index, conventional semen parameters, blood microelements and seminal plasma reactive oxygen species (ROS) in patients with male infertility to determine the association between each of the above male physiological parameters and DNA fragmentation index and infertility. Eighty cases of infertile males and 20 cases of normal males with children were divided into the infertility and control groups, respectively. Sperm DNA fragmentation index, conventional semen parameters, serum microelement content and seminal plasma ROS levels were detected, and the existing correlation between sperm DNA fragmentation index and the various physiological parameters were studied...

REVIEW
Gerrit Glas
This paper gives an analysis of some conceptual issues in the neuroscientific study of empathy. The focus will almost exclusively be on a seminal paper by Decety and Jackson (2004) on the functional architecture of empathy. The authors withstand reductionistic tendencies in the exposition of what their findings might mean for the psychology of social cognition. They are aware of the thorny conceptual issues that arise when attempting to bridge intuitive folk psychological conceptions of empathy with explanations offered by social psychology, developmental science, and, most of all, neuroscience...

Characterization of intratumoral heterogeneity is critical to cancer therapy, as presence of phenotypically diverse cell populations commonly fuels relapse and resistance to treatment. Although genetic variation is a well-studied source of intratumoral heterogeneity, the functional impact of most genetic alterations remains unclear. Even less understood is the relative importance of other factors influencing heterogeneity, such as epigenetic state or tumor microenvironment. To investigate the relationship between genetic and transcriptional heterogeneity in a context of cancer progression, we devised a computational approach called HoneyBADGER to identify copy number variation and loss-of-heterozygosity in individual cells from single-cell RNA-sequencing data...

Relatively spared during most of the timeline of normal aging, semantic memory shows a subtle yet measurable decline even during the pre-clinical stage of Alzheimer's disease. This decline is thought to reflect early neurofibrillary changes and impairment is detectable using tests of language relying on lexical-semantic abilities. A promising approach is the characterization of semantic parameters such as typicality and age of acquisition of words, and propositional density from verbal output. Seminal research like the Nun Study or the analysis of the linguistic decline of famous writers and politicians later diagnosed with Alzheimer's disease supports the early diagnostic value of semantic processing and semantic memory...

Varicocele has a common association with male infertility, but its exact role is still debated. Apoptosis has been suggested as one of the mechanisms of varicocele-associated infertility. Granulysin is a molecule that plays a role in apoptosis with no previous study about its role in male infertility. This case-controlled study aimed to assess seminal plasma granulysin level in infertile patients with varicocele. This study involved 90 men that were allocated into fertile normozoospermic men (n = 20), infertile men without varicocele (n = 30) and infertile men with varicocele (n = 40)...

Obesity is characterized by mild chronic inflammation that is linked with impaired iron homeostasis. Studies in human and murine show that there is a transgenerational epigenetic inheritance via the gametes in obesity; however, there is little information on changes in the expression of microRNAs related to inflammation and iron homeostasis in spermatozoa from obese subjects. The present study investigated the expression of microRNAs related to inflammation (miR-21 y miR-155) and iron nutrition (miR-122 and miR-200b) in plasma, peripheral blood mononuclear cells (PBMC) and spermatozoa from normozoospermic controls (Cn; n = 17; BMI: 24...

The objective of the present study was to describe the proteins from the seminal plasma of buffalo and correlate these proteins with sperm motility. Ejaculates from sixteen Murrah buffalo were used. Semen collection was performed by electroejaculation, and the ejaculate was evaluated by macroscopic (volume) and microscopic analysis (subjective motility and vigor, as well as sperm concentration). After the analysis, the samples were centrifuged (800g for 10 min and 10,000 for 30 min at 4 °C), and the supernatant (seminal plasma) was used to determine total protein concentration by the Bradford method...

Although semen analysis is routinely used to evaluate the male reproductive potential in the canine species, only a few authors have attempted to relate semen characteristics to donor traits, such as age or weight, and fertility. This study evaluated the effects of dogs' age (young: 0-24 months, adult: 25-84 months, old: >84 months), size (small: <15 kg, medium: 16-40 kg, large: >40 kg) and reason for semen collection (evaluation, artificial insemination, cryopreservation or research purposes) on the seminal characteristics and related the main seminal characteristics with fresh AI results...

Background: Murine models of atherosclerosis have been invaluable to gain mechanistic understanding of this chronic disease. Induction of atherosclerosis with relative ease in ApoE-/- and Ldlr-/- mice fed a Western-type diet to cause hyperlipidaemia has provided researchers with popular tools to manipulate and characterise the action of genes that affect atherogenesis. Seminal studies and reviews have discussed key phenotypic differences between different models and "target levels of hyperlipidaemia" have also been published...

Prolactin-inducible protein (PIP) is a glycoprotein found in body secretions from exocrine glands like saliva and seminal plasma. Important biological functions of PIP concentrations have been demonstrated, e.g. in tumor diagnosis and progression. PIP quantity has been also found useful to determine the success of chemotherapy of mammary carcinoma. Here, we present the analysis of the N-glycosylation of PIP isolated from different sources by LC-MS(/MS) and 1 H-NMR. We found a very uncommon N-type glycosylation of PIP in healthy individuals from both, seminal fluid and saliva...

Objectives: We conducted a systematic review and meta-analysis of observational case-control studies to evaluate markers of oxidative stress in seminal plasma of patients with male infertility. Background: Current evidence links oxidative stress to male infertility, in which multiple markers of oxidative stress have been widely detected, publishing inconsistent results with regard to the role of oxidative stress markers in the evaluation of male infertility. Therefore, a systematic review and meta-analysis on this issue is necessary...

BACKGROUND: Along with sperm, in many taxa ejaculates also contain large numbers of seminal fluid proteins (SFPs). SFPs and sperm are transferred to the mating partner, where they are thought to play key roles in mediating post-mating sexual selection. They modulate the partner's behavior and physiology in ways that influence the reproductive success of both partners, thus potentially leading to sexual conflict. Despite the presumed general functional and evolutionary significance of SFPs, their identification and characterization has to date focused on just a few animal groups, predominantly insects and mammals...

Humans act goal-oriented, and this idea is at the core of ideomotor theory (IT), which claims that actions are selected by mentally anticipating the sensory consequences brought about by the respective bodily movement (i.e., their action effects). Evidence for this effect anticipation mainly derives from the response-effect (R-E) compatibility (REC) paradigm: In the spatial domain, for example, a left response is produced faster (and sometimes less error-prone) if followed by a compatible left rather than an incompatible right action effect...

Growth hormone (GH) and insulin-like growth factor 1 (IGF-1) have been proposed to play a pivotal role in male infertility due to their anabolic effects. The aim of this study was to investigate possible associations between seminal plasma levels of GH and IGF-1 and sperm parameters. Fifty men participated in this study. Semen analysis was performed, while cell-free seminal plasma was collected following sperm centrifugation. Seminal plasma concentrations of IGF-1 and GH were determined by enzyme-linked immunosorbent assay (ELISA)...

The tolerance of sperm DNA structure to seminal plasma and freezing conditions has both clinical and basic biologic relevance. In this study, fresh (FS) or flash-frozen (FZ) stallion epididymal sperm were exposed (SP+ ) or unexposed (SP- ) to seminal plasma. Sperm were then evaluated to monitor the degree of change in DNA structure following challenge with chemical (dithiothreitol-DTT), oxidative (iron sulfate; FeSO4 ) or enzymatic (DNase I) potentiators of DNA damage. For sperm not treated with potentiators (controls), there was no effect of SP treatment (SP- vs...

Cimetidine is widely used for the treatment of digestive tract ulcers, but it induces testis injury. To explore the mechanisms underlying cimetidine-induced toxicity towards the testis, the effects of oral cimetidine on the reproductive system of male rats were assessed. Cimetidine was orally administered to male rats at 20, 40 or 120 mg/kg/day for 9 weeks. The rats were then euthanized, and serum, testis, epididymis, prostate gland, seminal vesicle, preputial gland, levator ani muscle and sphincter ani samples were collected...

OBJECTIVES: To determine if the presence of adverse pathologic features in patients eligible for active surveillance are prognostic of poor oncologic outcomes, independent of pretreatment risk. PATIENTS & METHODS: A retrospective analysis was performed on patients who underwent radical prostatectomy at two institutions (CCF, MSKCC) between 1987-2008 and who had subsequent follow-up. Rates of biochemical recurrence, metastasis and death from prostate cancer were compared among patients with adverse pathologic features (Gleason ≥7, ≥pT3, or lymph node invasion) based on D'Amico clinical risk (low vs...

Schwannomas rarely occur in seminal vesicles. Here, we report a schwannoma of the left seminal vesicle. A 55-year-old man presented no clinical symptoms, and a mass in the left region of the seminal vesicle was found incidentally in a medical examination. A computed tomography and magnetic resonance imaging of pelvic were obtained and revealed a 5.17 × 2.59 × 3.5 cm mass on the left seminal vesicle. Transrectal ultrasound-guided seminal biopsy revealed a diagnosis of seminal vesical schwannoma. Laparoscopic resection of the tumour was performed...
