The aim of the present study was to provide an inclusive and realistic account of the offense processes of naturally occurring, sexually exploitative interactions between offenders and victims that took place via Internet communication platforms, and develop an offense process diagram of online sexual grooming and abuse. Five case series, comprising 29 transcripts of 22 interactions, were analyzed using the qualitative approach of thematic analysis. Police reports were reviewed for descriptive and case-specific information...

The mechanism of pollinator attraction is predicted to strongly influence both plant diversification and the extent of pollinator sharing between species. Sexually deceptive orchids rely on mimicry of species-specific sex pheromones to attract their insect pollinators. Given that sex pheromones tend to be conserved among related species, we predicted that in sexually deceptive orchids, (i) pollinator sharing is rare, (ii) closely related orchids use closely related pollinators and (iii) there is strong bias in the wasp lineages exploited by orchids...

DIP-STRs are compound markers formed by a deletion/insertion polymorphism linked to a microsatellite. They enable the deconvolution of unbalanced DNA mixtures from two individuals, up to 1000 fold excess of one contributor. In practice, this novel tool allows to test for the presence of a DNA of interest in traces appearing not useful because of the masking effect of the major DNA contributor. Thus far two sets of DIP-STRs have been published: the first set was described as proof-of-principle, while the second set was specifically developed for forensic applications...

It is estimated that 21 million people are trafficked worldwide, including 11.4 million women and girls. Approximately 4.5 million are forced to do sexual labor. The exact prevalence of human trafficking is difficult to ascertain, however, given the limitations of data collection in an illegal industry. Obstetrician-gynecologists should not only be aware of the widespread nature of human trafficking, but also have the tools to assess patients for trafficking and respond to victim identifications. Patients may present with signs of physical abuse, depression, anxiety, posttraumatic stress disorder, substance use, sexually transmitted infections, pregnancy, and nonspecific somatic complaints...

Commercially sexually exploited children and adolescents ("commercially exploited youth")present numerous clinical challenges that have led some mental health providers to question whether current evidence-based treatments are adequate to address the needs of this population. This paper 1) addresses commonalities between the trauma experiences, responses and treatment challenges of commercially exploited youth and those of youth with complex trauma; 2) highlights the importance of careful assessment to guide case conceptualization and treatment planning for commercially exploited youth; and 3) describes strategies for implementing Trauma-Focused Cognitive Behavioral Therapy for complex trauma specific to these youth...

Chalcone synthase constitutes a functionally diverse gene family producing wide range of flavonoids by catalyzing the initial step of the phenylpropanoid pathway. There is a pivotal role of flavonoids in pollen function as they are imperative for pollen maturation and pollen tube growth during sexual reproduction in flowering plants. Here we focused on medicinally important fruit-bearing shrub Grewia asiatica. It is a rich repository of flavonoids. The fruits are highly acclaimed for various putative health benefits...

Commercial sexual exploitation of children has emerged as a critical issue within child welfare, but little is currently known about this population or effective treatment approaches to address their unique needs. Children in foster care and runaways are reported to be vulnerable to exploitation because they frequently have unmet needs for family relationships, and they have had inadequate supervision and histories of trauma of which traffickers take advantage. The current article presents data on the demographic characteristics, trauma history, mental and behavioral health needs, physical health needs, and strengths collected on a sample of 87 commercially sexually exploited youth...

The sexual behavioral system evolved to motivate reproductive acts by arousing sexual desire. Building on the idea that this system has also been "exploited" by evolutionary processes to promote enduring bonds between romantic partners, the present article introduces an integrative model that delineates the functional significance of sexual desire in relationship formation and maintenance. This model explains why individuals' sexual reaction to their partner is context-dependent, clarifying how changes in the nature of interdependence over the course of relationships alter the ways in which specific predictors of sexual desire tend to promote (or inhibit) desire and thereby affect relationship depth and stability...

BACKGROUND: Human trafficking is a form of modern slavery that involves the forced movement of people internally within countries, or externally across borders. Victims who are trafficked for sexual exploitation are subject to repeated, multiple trauma, and high rates of mental health problems including posttraumatic stress disorder (PTSD) have been found. Narrative exposure therapy (NET) is an evidence-based treatment for PTSD. METHODS: In this retrospective audit, we record the results of NET to treat 10 women who had been trafficked for sexual exploitation who were diagnosed with PTSD...

AIM: To analyse the accounts of staff, family and residents in order to advance ethical insights into intimacy and sexuality in residential care. BACKGROUND: Discourses of ageing readily construct people in residential aged care as post-sexual, vulnerable and at risk of sexual exploitation and therefore expressions of intimacy and sexuality may be responded to as deviant and inherently risky. Staff may manage decision-making tacitly, without recourse to policies and education...

BACKGROUND: The presence of low complexity and repeated regions in genomes often results in difficulties to assemble sequencing data into full chromosomes. However, the availability of full genome scaffolds is essential to several investigations, regarding for instance the evolution of entire clades, the analysis of chromosome rearrangements, and is pivotal to sexual crossing studies. In non-conventional but industrially relevant model organisms, such as the ascomycete Trichoderma reesei, a complete genome assembly is seldom available...

Approximately 20% of species in the fungal kingdom are only known to reproduce by asexual means despite the many supposed advantages of sexual reproduction. However, in recent years, sexual cycles have been induced in a series of emblematic "asexual" species. We describe how these discoveries were made, building on observations of evidence for sexual potential or "cryptic sexuality" from population genetic analyses; the presence, distribution, and functionality of mating-type genes; genome analyses revealing the presence of genes linked to sexuality; the functionality of sex-related genes; and formation of sex-related developmental structures...

In ants, dispersal strategies and morphology of female sexuals are generally linked to the mode of colony founding. In species using long-range dispersal tactics, queen/worker dimorphism is generally high and young queens are able to initiate new colonies by themselves, using their metabolic reserves. By contrast, in species using short-range dispersal strategies, queen/worker dimorphism is generally low and, due to their limited metabolic reserves, queens have lost the capacity to raise their brood alone and to found their colony independently...

Neisseria gonorrhoeae causes the sexually transmitted infection gonorrhea, which is highly prevalent worldwide and has a major impact on reproductive and neonatal health. The "superbug" status of N. gonorrhoeae necessitates development of drugs with different mechanisms of action. Here, we focused on targeting the nitrite reductase AniA, which is a pivotal component of N. gonorrhoeae anaerobic respiration and biofilm formation. Our studies showed that gonococci expressing AniA containing altered catalytic residues, D137A and H280A, failed to grow under anaerobic conditions demonstrating that the nitrite reductase function is essential...

Background: Elder abuse (EA) is a global public health issue. However, no prior longitudinal research has quantified the incidence of EA, which is critical to understand risk factors and future prevention strategies. Methods: The study is based on a longitudinal cohort design. We followed 2,713 U.S. Chinese older adults who agreed to participate in the study within 2011 to 2015. A structured questionnaire was used to collect data regarding the 2-year incidence of EA and its subtypes...

Sexual segregation in foraging occurs in many animal species, resulting in the partitioning of resources and reduction of competition between males and females, yet the patterns and drivers of such segregation are still poorly understood. We studied the foraging movements (GPS-tracking), habitat use (habitat modelling) and trophic ecology (stable isotope analysis) of female and male Cory's shearwaters Calonectris borealis during the mid chick-rearing period of six consecutive breeding seasons (2010-2015). We found a clear sexual segregation in foraging in years of greater environmental stochasticity, likely years of lower food availability...

The commercial sexual exploitation of children is a public health problem and a serious violation of the rights of children and adolescents. The response to this problem has been affected by the meanings and practices of the actors involved. In order to contribute to a better understanding of the problem, a qualitative social study using a grounded theory approach was carried out between 2014 and 2015. The aim was to understand the meanings and practices regarding this issue of people who spend time in an area of the city center with a high presence of commercial sexual exploitation of children and adolescents...

The expansion of primordial germ cells (PGCs), the precursors for the oocytes and spermatozoa, is a key challenge in reproductive biology/medicine. Using a chemical screening exploiting PGC-like cells (PGCLCs) induced from mouse embryonic stem cells (ESCs), we here identify key signaling pathways critical for PGCLC proliferation. We show that the combinatorial application of Forskolin and Rolipram, which stimulate cAMP signaling via different mechanisms, expands PGCLCs up to ~50-fold in culture. The expanded PGCLCs maintain robust capacity for spermatogenesis, rescuing the fertility of infertile mice...

The reproductive biology of three commercially significant seabream species (family: Sparidae) Acanthopagrus schlegelii, Evynnis cardinalis and Pagrus major, taken from Hong Kong and adjacent northern South China Sea (SCS) waters, were investigated for their sexual patterns, spawning seasons, length at maturity and exploitation in relation to their conservation and management status. Histological analysis showed E. cardinalis and P. major to be functionally gonochoristic, the latter having a bisexual juvenile stage and being a rudimentary hermaphrodite...

There are currently 1.5 million undocumented Asians and Pacific Islanders (APIs) in the US. Undocumented API young adults, in particular, come of age in a challenging political and social climate, but little is known about their health outcomes. To our knowledge, this is the first study to assess the psychosocial needs and health status of API undocumented young adults. Guided by social capital theory, this qualitative study describes the social context of API undocumented young adults (ages 18-31), including community and government perceptions, and how social relationships influence health...
