The aim of the present research is to study the effect of pH values on the sperm rheotaxis properties. Semen collected from bulls was diluted with SOF medium (1:10). pH of the medium was adjusted using a digital pH meter to the following pH values: 6.0, 6.2, 6.4, 6.4, 6.8, 7.0. All kinetic parameters of sperm (n = 3,385) were determined through a computer-assisted sperm analysis (CASA) system using microfluidic devices with controlled flow velocity. The following parameters were determined: total motility (TM%), positive rheotaxis (PR%), straightline velocity (VSL, μm/s), average path velocity (VAP, μm/s), linearity (LIN, as VSL/VCL, %), beat cross-frequency (BCF, Hz) and curvilinear velocity (VCL, μm/s)...

PURPOSE: Prostatitis is a very common urogenital disease of the male with prevalence ranging from 2.2 to 9.7% worldwide. Interestingly, some recent evidences have showed a significant association between chronic prostatitis (CP) and male infertility including a detrimental effect on sperm parameters, reduction of zinc concentration on semen sperm and production of anti-semen antibodies (ASAs). The aim of the current meta-analysis was to evaluate the association between CP and alteration of semen parameters...

Background. In most reports on ECMO treatment, advanced age is classified as a contraindication to VA ECMO. We attempted to investigate whether advanced age would be a main risk factor deciding VA ECMO application and performing VA ECMO support. We determined whether advanced age should be regarded as an absolute or relative contraindication to VA ECMO and could affect weaning and survival rates of VA ECMO patients. Methods. VA ECMO was performed on 135 adult patients with primary cardiogenic shock between January 2010 and December 2014...

Most men with hematospermia or hemospermia (HS) are young (<40 years of age), presenting with transient or episodic HS without other signs or symptoms of disease. The condition is self-limiting in most cases and idiopathic in nature. When a cause can be identified, infections of the urogenital tract are the most common. Imaging does not play a role in this patient population. In older men (>40 years of age), clinical screening for prostate cancer is advised. Furthermore, when HS is persistent or has symptoms, causes include obstruction or stricture at the level of the verumontanum, calcifications or calculi in the prostate, ejaculatory ducts or seminal vesicles, and cysts arising within these structures...

Melatonin (MLT) is present in seminal plasma (SP) of mammalian species, including pigs, and it is credited with antioxidant properties. This study aims to identify the sources of variation and the role of boar SP MLT on sperm quality and functionality and in vivo fertilizing ability of liquid-stored semen doses used in AI programs. The SP MLT was measured using an ELISA kit in a total of 219 ejaculates collected from 76 boars, and reproductive records of 5,318 AI sows were recorded. Sperm quality was assessed according to motility (computer-aided sperm analysis) and viability (cytometry evaluation)...

PURPOSE: To provide a benchmark for seminal vesicle (SV) margin selection to account for intrafractional motion and to investigate the effectiveness of 2 motion surrogates in predicting intrafractional SV coverage. METHODS AND MATERIALS: Fifteen prostate patients were studied. Each patient had 5 pairs (1 patient had 4 pairs) of pretreatment and posttreatment cone beam CTs (CBCTs). Each pair of CBCTs was registered on the basis of prostate fiducial markers. All pretreatment SVs were expanded with 1-, 2-, 3-, 4-, 5-, and 8-mm isotropic margins to form a series of planning target volumes, and their intrafractional coverage to the posttreatment SV determined the "ground truth" for exact coverage...

AIM: The main purpose of this study was to evaluate the differences in dose-volume histograms of IMRT treatments for prostate cancer based on the delineation of the main organs at risk (rectum and bladder) as solid organs or by contouring their wall. BACKGROUND: Rectum and bladder have typically been delineated as solid organs, including the waste material, which, in practice, can lead to an erroneous assessment of the risk of adverse effects. MATERIALS AND METHODS: A retrospective study was made on 25 patients treated with IMRT radiotherapy for prostate adenocarcinoma...

The present study was conducted to identify the major proteome of the sperm-rich fraction and prostatic fraction of canine seminal plasma. Three semen samples from four healthy dogs were obtained by digital manipulation. The pre-sperm fraction, sperm-rich fraction and prostatic fraction were separated from each ejaculate. Immediately after sperm analysis, a protease inhibitor was added to the sperm-rich fraction and prostatic fraction, and the fractions were separately centrifuged and frozen at -80 °C. The samples were thawed, re-centrifuged, and the total protein concentration was determined...

Despite being discovered almost 50years ago little is known regarding the genetic profile of ductal adenocarcinoma of the prostate (DAC). In recent years, progress has been made in the understanding of the genetics of acinar adenocarcinomas and at least seven genetically different subtypes have been identified. DAC is known to present at an advanced stage with a high rate of extraprostatic extension and seminal vesicle invasion, and a decreased interval to biochemical recurrence and the development of metastatic disease, when compared to acinar adenocarcinoma...

Introduction: There is increasing interest in PET/CT with PSMA tracers for imaging of prostate cancer due to higher detection rates of prostate cancer lesions as compared to PET/CT with choline. For (68)Ga-PSMA-11 tracers, late imaging at 180 min post injection (p.i.) instead of imaging at 45-60 min p.i. improves detection of prostate cancer lesions. For (18)F-DCFPyL improved detection rates has recently been reported in a small pilot study. In this study, we report the effects of PET/CT imaging at 120 minutes p...

DNA methylation patterns have the ability to reveal the activities of genes within a certain tissue at a particular time point. Tissue-specific DNA methylation patterns have been previously investigated for their applicability in the identification of forensically relevant body fluids, however there is still a lack in robust markers. While following a genome-wide scale investigation has a great potential to reveal useful tissue-specific changes, a gene-targeted approach can also lead to significant outcomes, especially in genomic locations not included in the genome-wide experiments...

Pycnogenol (PYC), an extract of pine bark, is known to have photoprotective, antimicrobial, antioxidant, and anti-inflammatory properties. An in vivo study was conducted to evaluate the effects of PYC treatment on wound healing in 48 adult male Sprague-Dawley rats, of which 24 were injected with a single dose of alloxan to induce diabetes. Three (3) excisional skin wounds (1.3 cm x 1.3 cm x 2 mm) were created in each healthy and diabetic animal. One (1) wound in each animal was left untreated, 1 was treated daily with a cleanser (ethacridine lactate) and covered with silver sulfadiazine (SSD), and 1 was treated with PYC powder (30 mg)...

BACKGROUND: Oxidative stress affects negatively the sperm quality. For maintaining the pro/antioxidative balance, some metal ions (e.g. copper, zinc, iron, selenium), which are co-factors of the antioxidant enzymes, are essential. However, iron and copper could act as prooxidants inducing oxidative damage of spermatozoa. AIMS: This study aims to reveal a possible correlation between the concentrations of some metal ions (iron, copper, zinc, and selenium) in human seminal plasma, oxidative stress, assessed by malondialdehyde (MDA) and total glutathione (tGSH) levels, and semen quality, assessed by the parameters count, motility, and morphology...

In 1952, W. E. Hick published an article in the Quarterly Journal of Experimental Psychology, "On the Rate of Gain of Information." It played a seminal role in the cognitive revolution and established one of the few widely acknowledged laws in psychology, relating choice reaction time to the number of stimulus-response alternatives (or amount of uncertainty) in a task. We review the historical context in which Hick conducted his study and describe his experiments and theoretical analyses. We discuss the article's immediate impact on researchers, as well as challenges to and shortcomings of Hick's law and his analysis, including effects of stimulus-response compatibility, practice, very large set sizes, and sequential dependencies...

STUDY QUESTION: Can 1H Magnetic Resonance Spectroscopy (MRS) be used to obtain information about the molecules and metabolites in live human spermatozoa? SUMMARY ANSWER: Percoll-based density gradient centrifugation (DGC) followed by a further two washing steps, yielded enough sperm with minimal contamination (<0.01%) from seminal fluid to permit effective MRS which detected significant differences (p < 0.05) in the choline/glycerophosphocholine, lipid and lactate regions of the 1H MRS spectrum between sperm in the pellet and those from the 40/80% interface...

Chlamydia trachomatis is considered as the bacterium that is more sexually transmitted as cause of male urethritis, epididymitis, orchitis and infertility. A total of 116 semen samples of men whose couples are infertile women were analysed. The quality of the semen was measured by standard procedures recommended by WHO while C. trachomatis was detected by the PCR assay. Thirty-seven semen samples were positive for C. trachomatis (31.9%). Regarding semen analysis, no different values were observed between positive and negative samples to C...
