Evolutionary interests of males and females are usually not the same, leading to different reproductive roles of the sexes. This results in sexual conflict, where a trait that is beneficial for one sex is detrimental to the other (Parker, 1979). Sexual conflict may take one of two forms. Intralocus sexual conflict is expressed when the direction of selection on a shared trait changes depending on the sex (Chippindale & Rice, 2001; Bonduriansky & Chenoweth, 2009).

Signals and cues are fundamental to social interactions. A well-established concept in the study of animal communication is an amplifier, defined as a trait that does not add extra information to that already present in the original cue or signal, but rather enhances the fidelity with which variation in the original cue or signal is correctly perceived. Attenuators as the logical compliment of amplifiers: attenuators act to reduce the fidelity with which variation in a signal or cue can be reliably evaluated by the perceivers...

STUDY QUESTION: What happens to the gut microbiota during development of murine endometriosis? SUMMARY ANSWER: Mice with the persistence of endometrial lesions for 42 days develop a distinct composition of gut microbiota. WHAT IS KNOWN ALREADY: Disorders in the immune system play fundamental roles in changing the intestinal microbiota. No study has used high-throughput DNA sequencing to show how endometriosis changes the gut microbiota, although endometriosis is accompanied by abnormal cytokine expression and immune cell dysfunction...

STUDY QUESTION: Are fetal fraction, test failure rate and positive predictive value (PPV) of cell-free fetal DNA (cffDNA) testing different in singleton IVF conceptions compared to spontaneous conceptions? SUMMARY ANSWER: Fetal fraction is significantly lower; test failure rate is higher and PPV of cffDNA testing is lower in singleton pregnancies conceived by IVF than those conceived spontaneously. WHAT IS ALREADY KNOWN: cffDNA testing, which analyses circulating cffDNA in maternal blood, has very high accuracy for detection of trisomy 21 in the general obstetric population...

PURPOSE OF REVIEW: The current article reviews recent data on treatment of acute headache patients in the acute care setting. RECENT FINDINGS: Intravenous fluid hydration, a common component of emergency department (ED) migraine therapy, does not improve pain outcomes and leads to longer ED lengths of stay. Therefore, intravenous fluids should be administered only to migraine patients with clinical evidence of dehydration. Similarly, intravenous ketamine has garnered interest as a treatment for acute pain but does not provide substantial relief to migraine patients...

PURPOSE OF REVIEW: Metabolic syndrome (MS) describes the co-occurrence of conditions that increase one's risk for heart disease and other disorders such as diabetes and stroke. The worldwide increase in the prevalence of MS cannot be fully explained by lifestyle factors such as sedentary behavior and caloric intake alone. Environmental exposures, such as heavy metals, have been implicated, but results are conflicting and possible mechanisms remain unclear. To assess recent progress in determining a possible role between heavy metal exposure and MS, we reviewed epidemiological and model system data for cadmium (Cd), lead (Pb), and mercury (Hg) from the last decade...

REVIEW
D Carrieri, F A Peccatori, G Boniolo
'Right To Try' (RTT) laws originated in the USA to allow terminally ill patients to request access to early stage experimental medical products directly from the producer, removing the oversight and approval of the Food and Drug Administration. These laws have received significant media attention and almost equally unanimous criticism by the bioethics, clinical and scientific communities. They touch indeed on complex issues such as the conflict between individual and public interest, and the public understanding of medical research and its regulation...

By their nature, the most vexing social problems reflect collisions between social and economic interests of parties with highly divergent views and perspectives on the cause and character of what is at issue and the consequences that flow from it. Conflicts around biotechnology applications are good examples of these problems. When considering the potential consequences of proposed biotechnology applications, an enormous range of perspectives arise reflecting the breadth of different and often competing interests with a stake in life's future...

The vacuolar cysteine protease legumain can cleave and selectively rebuild peptide bonds, thereby vastly expanding the sequential repertoire of biomolecules. In this context, plant legumains have recently at-tracted particular interest. Furthermore, legumains have important roles in many physiological pro-cesses, including programmed cell death. Their efficient peptide bond ligase activity has gained tremen-dous interest in the design of cyclic peptides for drug design. However, the mechanistic understanding of these dual activities is incomplete and partly conflicting...

STUDY QUESTION: Is telomere length related to parity among a nationally representative sample of US reproductive age women? SUMMARY ANSWER: History of live birth was associated with shorter telomere length. WHAT IS KNOWN ALREADY: Shorter telomeres have been linked with a range of chronic health conditions and mortality and parity has been associated with health indicators. However, there is a lack of research on how parity relates to telomere length...

OBJECTIVE: To develop a clinical practice guideline for a simplified approach to medical cannabinoid use in primary care; the focus was on primary care application, with a strong emphasis on best available evidence and a promotion of shared, informed decision making. METHODS: The Evidence Review Group performed a detailed systematic review of 4 clinical areas with the best evidence around cannabinoids: pain, nausea and vomiting, spasticity, and adverse events. Nine health professionals (2 generalist family physicians, 2 pain management-focused family physicians, 1 inner-city family physician, 1 neurologist, 1 oncologist, 1 nurse practitioner, and 1 pharmacist) and a patient representative comprised the Prescribing Guideline Committee (PGC), along with 2 nonvoting members (pharmacist project managers)...

Joshua L Golubovsky, Haariss Ilyas, Jinxiao Chen, Joseph E Tanenbaum, Thomas E Mroz, Michael P Steinmetz
BACKGROUND CONTEXT: Postoperative Urinary Retention (POUR) is a very common post-operative complication of all surgeries (5 - 70%) that may lead to complications such as urinary tract infection (UTI), bladder over-distention, autonomic dysregulation, and increased postoperative length of stay (LOS). Within the field of spine surgery, the reported incidence of POUR is highly variable (5.6 - 38%). Lack of clear stratification of surgical level, spinal pathology, and inadequate sample size is a major limitation of available studies concerning POUR following spine surgery that may lead to inconsistency in the incidence of POUR and the ability to model its occurrence and consequences...

STUDY QUESTION: Is the natural killer (NK) cell receptor repertoire of endometrial NK (eNK) cells tissue-specific? SUMMARY ANSWER: The NK cell receptor (NKR) expression profile in pre-pregnancy endometrium appears to have a unique tissue-specific phenotype, different from that found in NK cells in peripheral blood, suggesting that these cells are finely tuned towards the reception of an allogeneic fetus. WHAT IS KNOWN ALREADY: NK cells are important for successful pregnancy...

Small animal veterinarians' opinions were investigated regarding the frequency and nature of ethical dilemmas encountered, beliefs regarding euthanasia and balancing client and animal interests, prevalence and value of ethics training and proposals to mitigate the stressful effects of ethical dilemmas. The majority (52 per cent) of 484 respondents in the USA indicated via an online survey experiencing an ethical dilemma regarding the interests of clients and those of their patients at least weekly. Scenarios involving client financial concerns were commonly reported causes of ethical conflicts...
