REVIEW
M Reza Razeghinejad, Jonathan S Myers
Primary angle closure disease spectrum varies from a narrow angle to advanced glaucoma. A variety of imaging technologies may assist the clinician in determining the pathophysiology and diagnosis of primary angle closure, but gonioscopy remains a mainstay of clinical evaluation. Laser iridotomy effectively eliminates the pupillary block component of angle closure; however, studies show that in many patients the iridocorneal angle remains narrow from underlying anatomic issues, and increasing lens size often leads to further narrowing over time...

INTRODUCTION: Assisted Reproductive Technologies (ART) is increasingly used to help infertile couples to have children around the world. A number of studies have been published reporting an increased risk of major malformations in children born following ART, especially an increased incidence of epigenetic diseases (ED). This study aimed to assess the incidence of epigenetic diseases with affected imprinting genes in infants or children from pregnancies obtained through IVF/ICSI compared to infants or children from pregnancies obtained spontaneously...

We present a theory to address the photoluminescence (PL) intensity and valley polarization (VP) dynamics in monolayer WSe$_2$, under the impact of excitonic dark states of both excitons and biexcitons. We find that the PL intensity of all excitonic channels including intravalley exciton (X$_{\rm b}$), intravalley biexciton (XX$_{\rm k,k}$) and intervalley biexciton (XX$_{\rm k,k^\prime}$) in particular for the {XX$_{\rm k,k}$} PL is enhanced by laser excitation fluence. In addition, our results indicate the anomalous temperature dependence of PL, i...

Historically, the gold standard for management of ureteropelvic junction obstruction (UPJO) has been open pyeloplasty. However, continued technological and surgical advances have ultimately led to the robotic approach. Continued advances in minimally invasive surgery have led to shorter hospital stays and hastened recovery. Here we present our step by step guide and video to robotic-assisted laparoscopic pyeloplasty.

The envelope is constantly being pushed to minimize the invasiveness of prostate cancer surgery without compromising oncologic or functional outcomes. Transperitoneal robot-assisted radical prostatectomy has certainly accomplished these goals. However, it is our intent to push the envelope even further, that is, to minimize the invasiveness of already minimally invasive surgery. To accomplish this lofty goal, we borrowed the transperineal approach from open surgery and fused it with the latest robotic technology to innovate an extraperitoneal robotic prostatectomy technique that is less invasive than the traditional robotic technique...

During the last decade, the synthesis and application of metal-organic framework (MOF) nanosheets has received growing interest, showing unique performances for different technological applications. Despite the potential of this type of nanolamellar materials, the synthetic routes developed so far are restricted to MOFs possessing layered structures, limiting further development in this field. Here, a bottom-up surfactant-assisted synthetic approach is presented for the fabrication of nanosheets of various nonlayered MOFs, broadening the scope of MOF nanosheets application...

This study presents an economic assessment of controlled ovarian stimulation in assisted reproductive technology procedures in Spain, comparing the use of corifollitropin alfa and various forms of recombinant follicle-stimulating hormone (rFSH) in women of advanced maternal age. A cost-minimization analysis (CMA) was performed to assess the cost per cycle of controlled controlled ovarian stimulation, including only direct costs associated with the stimulation phase. The CMA was based on the population characteristics, the protocol, and the results obtained from the PURSUE study, taking into account 9 days of controlled controlled ovarian stimulation and 300 IU rFSH/day...

Many patients who might benefit from treatment using assisted reproductive technology (ART) do not receive it, raising critical questions of why, and how best to overcome existing barriers. In-depth interviews of approximately 1 h each were conducted with 27 ART providers (17 physicians and 10 other healthcare providers). These interviewees suggest that non-ART providers may serve as gatekeepers in a complex system, involving not only individual-level, but also dyadic and institutional, processes and factors related to provider-patient relationships...

In a nationwide population-based birth cohort study in Japan, pregnant women and their partners were evaluated for psychological distress as part of the first and second/third trimester health checks. Participants were divided into three groups: an infertility group receiving assisted reproductive technology (ART) treatment (239 mothers and 151 fathers); an infertility group receiving non-ART treatment (350 mothers and 215 fathers); and a spontaneous pregnancy group (8514 mothers and 5110 fathers). Data on maternal and child health as well as basic characteristics were collected via medical records and self-administered questionnaires...

Gestational surrogacy policy in the USA varies by state, but information on state differences is lacking. This study used data from the National Assisted Reproductive Technology Surveillance System from 2010 to 2014 to calculate state differences in gestational carrier cycle characteristics. Of the 662,165 in-vitro fertilization cycles in the USA between 2010 and 2014, 16,148 (2.4%) used gestational carriers. Non-USA residents accounted for 18.3% of gestational carrier cycles, and 29.1% of gestational carrier cycles by USA residents were performed in a state other than the state of residence of the intended parent...

This article compares the use of assisted reproductive technology (ART) and resultant kinship formations in four Middle Eastern settings: the Sunni Muslim Arab world, the Sunni Muslim but officially 'secular' country of Turkey, Shia Muslim Iran and Jewish Israel. This four-way comparison reveals considerable similarities, as well as stark differences, in matters of Middle Eastern kinship and assisted reproduction. The permissions and restrictions on ART, often determined by religious decrees, may lead to counter-intuitive outcomes, many of which defy prevailing stereotypes about which parts of the Middle East are more 'progressive' or 'conservative'...

Exosomes are a potential source of cancer biomarkers. Probing tumor-derived exosomes can offer a potential non-invasive way to diagnose cancer, assess cancer progression, and monitor treatment responses. Novel molecular methods would facilitate exosome analysis and accelerate basic and clinical exosome research. Methods: A standard gold-coated glass microscopy slide was used to develop a miniaturized affinity-based device to capture exosomes in a target-specific manner with the assistance of low-cost 3-D printing technology...

POU5F1 is a transcription factor and master regulator of cell pluripotency with indispensable roles in early embryo development and cell lineage specification. The role of embryonic POU5F1 in blastocyst formation and cell lineage specification differs between mammalian species but remains completely unknown in cattle. The CRISPR/Cas9 system was utilized for targeted disruption of the POU5F1 gene by direct injection into zygotes. Disruption of the bovine POU5F1 locus prevented blastocyst formation and was associated with embryonic arrest at the morula stage...

The area of assistive technology has a long history of technological ingenuity and innovation. In order to ensure that the benefits of assistive technology are equitably distributed across the population and life course, it is necessary to adopt a systemic approach to the area. We describe examples of systems thinking and non-systems thinking across 10 Ps. These Ps are People (or users, as the primary beneficiaries of assistive technology), Policy, Products, Personnel, Provision (as key strategic drivers at systems level); and Procurement, Place, Pace, Promotion and Partnership (as key situational factors for systems)...

This work evaluated the effectiveness of rice straw pretreatment using a TiO₂/UV system in the presence of oxidants. The effects of TiO₂ concentrations, pH and photocatalysis time were investigated. Inorganic oxidants including H₂O2, K₂S₂O₈, and KIO₄ were added to further enhance the effect on enzymatic hydrolysis of rice straw. The TiO₂/UV/ H₂O₂ pretreatment showed a higher amount of released reducing sugar (8.88 ± 0.10 mg/mL, compared to 5.47 ± 0.03 mg/mL in untreated sample). Composition analyses of rice straw after the TiO₂/UV/H₂O₂ pretreatment showed partial lignin and hemicellulose removal...
