Absence of laws regarding sperm and oocyte donation in Japan and the impacts on donors, parents, and the people born as a result

An absence of any statutory law in Japan regarding donor conception creates uncertainty about the status of donors in relation to the child(ren) born as a result. Laws that provide for certainty regarding the status of the donor are called for, as are laws that address donor anonymity. It would be pragmatic to introduce a prospective system that requires open donation, allowing information to be recorded and released to donor-conceived people upon request. For past donations, a voluntary register should be established, which would allow those people who are seeking information to register this

Real-time 3D Tracking of Articulated Tools for Robotic Surgery

In robotic surgery, tool tracking is important for providing safe tool-tissue interaction and facilitating surgical skills assessment. Despite recent advances in tool tracking, existing approaches are faced with major difficulties in real-time tracking of articulated tools. Most algorithms are tailored for offline processing with pre-recorded videos. In this paper, we propose a real-time 3D tracking method for articulated tools in robotic surgery. The proposed method is based on the CAD model of the tools as well as robot kinematics to generate online part-based templates for efficient 2D matching and 3D pose estimation. A robust verification approach is incorporated to reject outliers in 2D detections, which is then followed by fusing inliers with robot kinematic readings for 3D pose estimation of the tool. The proposed method has been validated with phantom data, as well as ex vivo and in vivo experiments. The results derived clearly demonstrate the performance advantage of the proposed method when compared to the state-of-the-art.Comment: This paper was presented in MICCAI 2016 conference, and a DOI was linked to the publisher's versio

Survival and Growth of American Alligator (Alligator mississippiensis) hatchlings after artificial incubation and repatriation

Hatchling American Alligators (Alligator mississippiensis) produced from artificially incubated wild eggs were returned to their natal areas (repatriated). We compared artificially incubated and repatriated hatchlings released within and outside the maternal alligator’s home range with naturally incubated hatchlings captured and released within the maternal alligator’s home range on Lake Apopka, Lake Griffin, and Orange Lake in Florida. We used probability of recapture and total length at approximately nine months after hatching as indices of survival and growth rates. Artificially incubated hatchlings released outside of the maternal alligator’s home range had lower recapture probabilities than either naturally incubated hatchlings or artificially incubated hatchlings released near the original nest site. Recapture probabilities of other treatments did not differ significantly. Artificially incubated hatchlings were approximately 6% shorter than naturally incubated hatchlings at approximately nine months after hatching. We concluded that repatriation of hatchlings probably would not have long-term effects on populations because of the resiliency of alligator populations to alterations of early age-class survival and growth rates of the magnitude that we observed. Repatriation of hatchlings may be an economical alternative to repatriation of older juveniles for population restoration. However, the location of release may affect subsequent survival and growth

Application of integrated fluid-thermal-structural analysis methods

Hypersonic vehicles operate in a hostile aerothermal environment which has a significant impact on their aerothermostructural performance. Significant coupling occurs between the aerodynamic flow field, structural heat transfer, and structural response creating a multidisciplinary interaction. Interfacing state-of-the-art disciplinary analysis methods is not efficient, hence interdisciplinary analysis methods integrated into a single aerothermostructural analyzer are needed. The NASA Langley Research Center is developing such methods in an analyzer called LIFTS (Langley Integrated Fluid-Thermal-Structural) analyzer. The evolution and status of LIFTS is reviewed and illustrated through applications

Trying for a second chance: Iranian infertile couples’ experiences after failed ART

Introduction: Despite significant advances, only 35% infertile couples conceive after ART. If IVF is unsuccessful, couples will need to decide whether to proceed again with assisted conception. The aim of this study was to explore Iranian infertile couples’ experiences after failed ART to continue treatment. Methods: In this qualitative study participants were selected using purposeful sampling method. Data were collected using 29 semi-structured face-to-face in-depth interviews at a regional Infertility Center from April 2016 to June 2017. All interviews were recorded, transcribed verbatim, and analyzed with conventional content analysis method using MAXQDA software. Results: Our findings suggest that couples’ decisions to continue treatment after unsuccessful ART is shaped by their social, emotional and financial circumstances. We have constructed two themes to describe their experiences: support to continue and trying for a second chance. Conclusion: Our findings suggest that good marital and family support networks can support infertile couples during this period of decision making. Considering the depression and anxiety caused by failed ARTs, which itself could affect the success rate of any further ARTs, the clinical team should effectively assess psychological readiness of couples who decide to continue with another ART after unsuccessful treatment

A qualitative study of the experiences of Iranian infertile couples after unsuccessful assisted reproductive technologies

Objectives: Assisted reproductive technologies (ARTs) give hope to some infertile couples; however, in vitro fertilization (IVF) is expensive and not subsidized by the Iranian state. More than 75% of IVF cycles in Iranian couples are unsuccessful. The aim of this paper is to describe the experiences of Iranian infertile couples after unsuccessful treatment. Materials and Methods: In this descriptive qualitative study, 36 participants including 29 Iranian infertile couples recruited after unsuccessful ART treatments, five infertility treatment team members and 2 relatives of infertile couples were interviewed at an Infertility Center in Northeastern Iran from April 2016 to June 2017. Data were collected using semi-structured, face-to-face interviews. Data analysis was carried out following Sandelowski. Results: Iranian infertile couples’ experiences following failed ART cycles are described. The findings presented here show that Iranian infertile couples experience stressors during treatment cycles and systemic challenges which may be unique to the Iranian cultural context. Conclusions: Iranian infertile couples face particular challenges related to the cultural context in which ARTs are delivered. Further exploration of the effects of culture on the experiences of failed ARTs needs to be considered by infertility clinics in Ira
