BACKGROUND: For prostate cancer treatment, treatment options with minimal side effects are desired. External beam radiation therapy (EBRT) is non-invasive, standard of care and delivered in either conventional fractionation over 8 weeks or with moderate hypo-fractionation over about 5 weeks. Recent advances in radiotherapy technology have made extreme hypo-fractionated stereotactic body radiation therapy (SBRT) of prostate cancer feasible, which has not yet been introduced as a standard treatment method in Germany...

This randomized controlled trial was conducted to examine the effects of 24 weeks of combined aerobic and resistance exercise training on seminal markers of inflammation and oxidative stress as well as markers of male reproductive function and reproductive performance in infertile patients. Of a total of 1296 infertile patients (aged 25-40 years) who were screened, 556 were randomly assigned to exercise (EX, n = 278) and non-exercise (NON-EX, n = 278) groups. Semen samples were taken before, 12 and 24 weeks as well as 7 and 30 days post intervention...

Ebola virus (EBOV) was discovered for the first time in 1976. It belongs to the family Filoviridae, which causes hemorrhagic fever that could lead to death in a few days. West Africa faced a major outbreak where symptoms appeared in the form of chills, myalgia, fever, diarrhea, and vomiting, and the disease finally reached a severe state as a result of hemorrhagic complications and failure of multiple organs. EBOV spreads by contact with body fluids of an infected person such as blood, saliva, urine, and seminal fluid, and also spreads by a contact with contaminated surfaces...

Equine arteritis virus (EAV) has the ability to establish persistent infection in the reproductive tract of the stallion (carrier) and is continuously shed in its semen. We have recently demonstrated that EAV persists within stromal cells and a subset of lymphocytes in the stallion accessory sex glands in the presence of a significant local inflammatory response. In the present study, we demonstrated that EAV elicits a mucosal antibody response in the reproductive tract during persistent infection with homing of plasma cells into accessory sex glands...

INTRODUCTION AND AIM: Surgical vasectomy remains the gold standard for fertility control in men. Endoluminal occlusion of the seminal ducts, thus avoiding an external incision, may become an appealing alternative to this approach. As our group has shown, nontraumatic endoscopic inspection of the seminal ducts is feasible in the human cadaver. We investigated the feasibility and reliability of occlusion using several commercially available medical sealing agents in the porcine vas deferens (VD)...

BACKGROUND: Whether spontaneous low levels of HIV-1 RNA in blood plasma correlate with low levels of HIV-1 RNA in seminal plasma has never been investigated in HIV controller (HIC) men so far. METHODS: HIC men enrolled in the ANRS CODEX cohort were eligible for the present study if they had no symptoms of sexually transmitted infections (STI). Two paired samples of blood and semen were collected four weeks apart. HIV-RNA was quantified in blood plasma (bpVL) and in seminal plasma (spVL), and cell-associated HIV-DNA was quantified in peripheral blood mononuclear cells (PBMC) and in non-sperm cells (NSC)...

REVIEW
Ashley K Randall, Guy Bodenmann
Stress is an all too common experience for people around the world. In the past 30 years, researchers have built upon traditional models of stress, which have focused on the individual, to explore stress' systemic effects. As such, the once thought individual experience of stress can now be conceptualized as a dyadic construct that affects both individuals within an interdependent dyad. Reviewing a selection of the literature published after Randall and Bodenmann's [1] seminal review on the impact of stress on close relationships, this review conceptualizes the associations between different types of stressors-particularly those that originate outside (external) and inside (internal) the relationship-and relationship satisfaction within romantic relationships...

BACKGROUND: Though the vast majority of seminal trials for locally advanced esophageal cancer (EC) utilized three-dimensional conformal radiotherapy (3DCRT), the advanced and highly conformal technology known as intensity-modulated radiotherapy (IMRT) can decrease doses to critical cardiopulmonary organs. To date, there have been no studies comparing both modalities as part of definitive chemoradiation (dCRT) for EC. Herein, we investigated local control and survival and evaluated clinical factors associated with these endpoints between cohorts...

Amyloids refer to a class of protein or peptide aggregates that are heterogeneous in size, morphology, and composition, and are implicated to play a central role in many neurodegenerative and systemic diseases. The strong correlation between biological activity and extent of aggregation of amyloidogenic proteins and peptides has led to an explosion of research efforts to target these materials with synthetic molecules or engineered antibodies to try to attenuate their function in disease pathology. Although many of these efforts to attenuate amyloid function have shown great promise in laboratory settings, the vast majority of work has been focused on targeting amyloids associated with neurologic diseases, which has been met with significant additional challenges that preclude clinical evaluation...

For two decades, the Pain & Policy Studies Group (PPSG), a global research program at the University of Wisconsin Carbone Cancer Center, has worked passionately to fulfil its mission of improving pain relief by achieving balanced access to opioids worldwide. PPSG's early work highlighted the conceptual framework of balance leading to the development of the seminal guidelines and criteria for evaluating opioid policy. It has collaborated at the global level with UN agencies to promote access to opioids and has developed a unique model of technical assistance to help national governments assess regulatory barriers to essential medicines for pain relief and amend existing or develop new legislation that facilitates appropriate and adequate opioid prescribing according to international standards...

The trauma of birth is an international concern for all childbearing women globally. Since changes in 1994 to the Diagnostic Statistical Manual (DSM) which included childbirth as a potentially traumatic event, several clusters of researchers, particularly representing the Scandinavian countries, the United Kingdom, and Australia, have emerged. Their research findings appear in numerous publications; yet, what is known from these studies is based on a variety of methodological designs and differing measurement tools making it difficult to draw many firm conclusions (Ayers, 2004 ; Ayers, Joseph, Mc-Kenzie-McHarg, Slade, & Wijma, 2008 )...

INTRODUCTION: We aimed to report on multiparametric MRI (mpMRI) characteristics of post-primary focal cryosurgery (PFC) patients suspected of biochemical recurrence (BCR) by the Phoenix criteria. METHODS: We retrospectively reviewed all patients at our institution who had undergone PFC. Prostate-specific antigen nadir was determined using 2 or more post-PFC values. Suspicion of BCR was determined using the Phoenix criteria (nadir + 2 ng/ml). At the discretion of the physician, pre-and post-PFC 3-T mpMRIs were obtained and in a few cases biopsies were performed...

Sexual fate of the sawfly, Athalia rosae (Hymenoptera: Tenthredinidae) is determined by the complementary sex determination (CSD) mechanism as is the case in honeybees. However, to date, genes involved in sex determination have not been identified in this species. In this study, we attempted to identify orthologs of complementary sex-determiner (csd), feminizer (fem), and doublesex (dsx) from the A. rosae genome, all of which are crucial components of the sex determination cascade in the honeybee. As a result, we identified a sawfly ortholog of dsx (designated as Ardsx)...
