Identification of circulating small non-coding RNAs in relation to male subfertility and reproductive hormones
Male subfertility is often associated with sub-optimal health status and traditional semen and hormone analysis reveal only limited information about the reduced fertility potential. Circulating small non-coding RNAs (sncRNAs) are paracrine and endocrine messengers, with prognostic potential. Here, we utilised small RNA-Seq to identify novel cell-free circulating sncRNAs that could act as potentia
Impact of Di-2-Ethylhexyl Phthalate Metabolites on Male Reproductive Function : a Systematic Review of Human Evidence
PURPOSE OF REVIEW: The purpose of this review is to systematically review the literature linking di-2-ethylhexyl phthalate (DEHP) exposure with effects on reproductive health in adult males. RECENT FINDINGS: Thirty-three papers were included of which 28 were cross-sectional. Twenty-one papers investigated semen samples, 18 investigated reproductive hormones, and three studies investigated time to

Testicular microlithiasis (TM) has been reported in up to 46% of men with testicular cancer. This has given rise to the suspicion that TM is a premalignant condition. In studies of healthy men there is, however, no association between TM and development of cancer. Nonetheless, patients with TM and contralateral testicular cancer, testicular atrophy, inhomogeneous parenchyma, infertility or a histo
Perfluoroalkyl substances and time to pregnancy in couples from Greenland, Poland and Ukraine
Background: Perfluoroalkyl substances (PFAS) are suggested to affect human fecundity through longer time to pregnancy (TTP). We studied the relationship between four abundant PFAS and TTP in pregnant women from Greenland, Poland and Ukraine representing varying PFAS exposures and pregnancy planning behaviors. Methods: We measured serum levels of perfluorooctanoic acid (PFOA), perfluorooctane sulfo
Aging, DNA damage, and reproductive outcome
Due to increasing life expectancy and a number of social factors, at least in the Western world, an increasing proportion of men who are considered to belong to an “older age group” have the wish of becoming fathers. One of the reasons is that many women postpone their first pregnancy, which automatically leads to higher age of the potential fathers. Furthermore, divorce and building new families

Carcinoma-in-situ of the testis - Is ultrasound of the testes useful as a screening method?
Testicular germ cell cancer is preceded by a pre-invasive stage called carcinoma-in-situ (CIS). The majority, if not all cases of CIS will progress into invasive cancer. Today, the only reliable way of diagnosing CIS is by performing open testicular biopsy. There is an ongoing search for non-invasive techniques for diagnosing early testicular neoplasia. The possibility of using ultrasound of the t

Semen quality in relation to xenohormone and dioxin-like serum activity among inuits and three european populations
BACKGROUND: Semen quality in humans may be influenced by exposure to endocrine-disrupting compounds. OBJECTIVES: We analyzed associations between semen characteristics and serum xenoestrogen receptor (XER), xenoandrogen receptor (XAR), and aryl hydrocarbon receptor (AhR) transactivity. XER and XAR activity were measured in serum samples cleared for endogenous steroid hormones and AhR activity in r
Xenoandrogenic activity in serum differs across European and inuit populations
BACKGROUND: Animal and in vitro studies have indicated that human male reproductive disorders can arise as a result of disrupted androgen receptor (AR) signalling by persistent organic pollutants (POPs). Our aim in the present study was to compare serum xenoandrogenic activity between study groups with different POP exposures and to evaluate correlations to the POP proxy markers 2,2',4,4',5,5-hexa

Facing metaphors as the most complex iconic signs: Toward a synthetic analysis of figuration in Greek street art
Cognitive linguistic and semiotic accounts of metaphors have often discussed the complex phenomenon of metaphor in various ways, often addressing factors such as universality and conventionality, context-sensitivity, cross-cultural variation and creativity, deliberateness and “multimodality”. However, in most cases, such factors are investigated in isolation (cf. Gibbs 2017). Therefore, we propose

Brain myoinositol as a potential marker of amyloid-related pathology : A longitudinal study
ObjectiveTo investigate the association between longitudinal changes in proton magnetic resonance spectroscopy (MRS) metabolites and amyloid pathology in individuals without dementia, and to explore the relationship between MRS and cognitive decline.MethodsIn this longitudinal multiple time point study (a subset of the Swedish BioFINDER), we included cognitively healthy participants, individuals w
Renal function after out-of-hospital cardiac arrest; The influence of temperature management and coronary angiography, a post hoc study of the target temperature management trial
Background: To elucidate the incidence of acute kidney injury (AKI) after out-of-hospital cardiac arrest (OHCA) and to examine the impact of target temperature management (TTM) and early coronary angiography on renal function. Methods: Post hoc analysis of the TTM trial, a multinational randomised controlled trial comparing target temperature of 33 °C versus 36 °C in patients with return of sponta

Interaction between smoking and genetic factors in the development of chronic bronchitis
Rationale: Smoking is a primary risk factor for chronic bronchitis, emphysema, and chronic obstructive pulmonary disease, but since not all smokers develop disease, it has been suggested that some individuals may be more susceptible to exogenous factors, such as smoking, and that this susceptibility could be genetically determined. Objectives: The aim of the present study was to assess, in a popul
Minskade utsläpp räcker inte för att rädda mångfalden
Klimatfrågan har under senare år rotat sig in i svenskens medvetande. Om detta vittnar nyord som ”klimatångest” och ”flygskam”. Det är på tiden. Men klimatförändringarna är inte den enda kris vi nu står inför och måste konfrontera.
