5, 95% confidence interval 0.8-8.1). Despite having higher rates of insurance coverage (51.2% versus 36.5%), non-Hispanic Black women were more likely to discontinue care (58.3% versus 40.2%) and less likely to achieve a live birth (53.0% versus 68.0%) than non-Hispanic White women.

Identification as non-Hispanic Black, and distance to the clinic, but not insurance coverage or zip code, were associated with increased risk of care discontinuation following an unsuccessful IVF cycle. In women ≤34 years old, HAC may be associated with a higher rate of care discontinuation.

What are the fertility preservation rates of transgender women and transgender men, and what are the factors that affect their decision-making?

This prospective study included 97 transgender women and 91 transgender men referred to the Gender Clinic of the study medical centre's Endocrinology Institute and to the Gan Meir Community Health Care Centre. The responders completed a 28-item questionnaire during 2018.

Most of the transgender women and transgender men wished to parent a child (67.4% and 61.9%, respectively, P = 0.447), but only 40.4% of the transgender women and 5.8% of the transgender men used fertility preservation (P < 0.001). The main reasons for not pursuing fertility preservation were unwillingness to postpone gender-affirming treatment (58.8% and 74.0%, respectively, P = 0.076), preference to adopt a child (58.8% and 60.9%, respectively, P = 0.818) and cost (44.9% and 60.9%, respectively, P = 0.086). Factors related to the fertility preservation process itself were specifically chosen by transgender men compared with transgender women as the reason for not pursuing this treatment, including distress caused by the fertility preservation technique (60.3% versus 29.3%, respectively, P = 0.006), fear of gender dysphoria caused by hormonal treatment (63.5% versus 28.3%, P = 0.002) and concern over the attitude of medical staff (44% versus 19%, P = 0.027).

Fertility preservation rates were considerably lower among transgender men than transgender women, strongly related to the fertility preservation process itself. Finding ways to overcome the obstacles confronted by transgender individuals, especially transgender men, will enhance their future biological parenting.

Does type of LH peak suppression (progesterone-primed ovarian stimulation [PPOS] versus gonadotrophin releasing hormone [GnRH] antagonist) affect oocyte competence, embryo development and live birth rates in recipients of vitrified donated oocytes?

Retrospective cohort study conducted between 2016 and 2018, involving 187 recipient cycles of donated vitrified oocytes. Oocyte donors were stimulated under LH suppression with desogestrel for PPOS (DSG group) or ganirelix GnRH antagonist (ANT group). Recipients younger than 50 years received vitrified oocytes from DSG donation cycles (DSG-R) or ANT donation cycles (ANT-R).

A mean of 10.07 ± 3.54 oocytes per recipient were warmed (survival rate of 80.7%), and 5.90 ± 2.89 were fertilized (fertilization rate 72.6%). Out of 187 recipients, 168 achieved embryo transfers. No significant differences were found in warming survival rates, fertilization rates and embryo development between DSG-R and ANT-R groups. SU11274 order Ninety-four clinical pregnancies and 81 live births were achieved. No statistically significant differences were found in clinical pregnancy rates (47.7% versus 52.5, P = 0.513) and live birth rates (39.5% versus 46.5%, P = 0.336) per recipient cycle between DSG-R and ANT-R, respectively. Multivariable logistic regression was applied to assess the effect of treating oocyte donors. Live birth rate adjusted for associated factors was not statistically different between vitrified oocytes from DSG or ANT (OR 0.74, 95% CI 0.37 to 1.47).

Reproductive outcomes of recipients of vitrified oocytes are not affected by donor PPOS treatment. PPOS is suitable for suppressing LH peak in elective fertility preservation and in freeze-all strategies.

Does revascularization of human ovarian grafts in a mouse model occur with equal efficiency from both sides of the cortex tissue?

Twenty-four frozen-thawed ovarian cortex pieces from 12 women were transplanted to immunodeficient mice, for 8 days to analyse graft revascularization using immunohistochemical detection of murine CD31, or for 8 weeks to evaluate follicle density (follicles/mm
). The CD31-positive vessel area and density were quantified using a custom-designed application. Three regions of interest (ROI) were defined in each tissue section the cortical side, the centre and the medullary side. Vessels were subdivided into three categories according to size microvessels (<300 µm
), small vessels (300-1000 µm
) and large vessels (>1000-3000 µm
).

No significant difference in the mean percentage of the CD31-positive vessel area was found between the three ROI (cortical side 3.9% ± 0.2%; centre 3.5% ± 0.2%; medullary side 4.0% ± 0.3%; P = 0.17), but a significantly lower density of vessels was found in the centre of the human ovarian grafts compared with the cortical and medullary sides (cortical side 323 ± 14 vessels/mm
; centre 240 ± 12 vessels/mm
; medullary side 301 ± 18 vessels/mm
; P < 0.001). Microvessels comprised 89-91% of all vessels in the three ROI. Follicle density in ungrafted cortex pieces was 51.8 ± 17.3 and 14.7 ± 3.7 follicles/mm
after 8 weeks of xenografting, resulting in a follicle survival rate of 28%.

Host revascularization was established equally efficiently from both sides of transplanted human ovarian cortex, suggesting that transplantation techniques ensuring revascularization from both sides of the ovarian graft could potentially facilitate faster graft revascularization.

Most plant organs are highly opaque to light, and their study under optical sectioning microscopes is therefore difficult. In animals, many protocols have been developed to make organs transparent to light using clearing protocols (CPs). By contrast, clearing plant tissues is challenging because of the presence of fibers and pigments. We describe progress in the development of plant CPs over the past 20 years through a modified taxonomy of CPs based on their physical and optical parameters that affect tissue properties. We also discuss successful approaches that combine CPs with new microscopy methods and their future applications in plant science research.The extracellular matrix (ECM) is a dynamic structure that surrounds and anchors cellular components in tissues. In addition to functioning as a structural scaffold for cellular components, ECMs also regulate diverse biological functions, including cell adhesion, proliferation, differentiation, migration, cell-cell interactions, and intracellular signaling events. Dermal fibroblasts (dFBs), the major cellular source of skin ECM, develop from a common embryonic precursor to the highly heterogeneous subpopulations during development and adulthood. Upon injury, dFBs migrate into wound granulation tissue and transdifferentiate into myofibroblasts, which play a critical role in wound contraction and dermal ECM regeneration and deposition. In this review, we describe the plasticity of dFBs during development and wound healing and how various dFB-derived ECM molecules, including collagen, proteoglycans, glycosaminoglycans, fibrillins and matricellular proteins are expressed and regulated, and in turn how these ECM molecules play a role in regulating the function of dFBs and immune cells. Finally, we describe how dysregulation of ECM matrix is associated the pathogenesis of wound healing related skin diseases, including chronic wounds and keloid.Advances in the field of human stem cells are often a source of public and ethical controversy. Researchers must frequently balance diverse societal perspectives on questions of morality with the pursuit of medical therapeutics and innovation. Recent developments in brain organoids make this challenge even more acute. Brain organoids are a new class of brain surrogate generated from human pluripotent stem cells (hPSCs). They have gained traction as a model for studying the intricacies of the human brain by using advancements in stem cell biology to recapitulate aspects of the developing human brain in vitro. However, recent observation of neural oscillations spontaneously emerging from these organoids raises the question of whether brain organoids are or could become conscious. At the same time, brain organoids offer a potentially unique opportunity to scientifically understand consciousness. To address these issues, experimental biologists, philosophers, and ethicists united to discuss the possibility of consciousness in human brain organoids and the consequent ethical and moral implications.Extremophiles have always garnered great interest because of their exotic lifestyles and ability to thrive at the physical limits of life. In hot springs environments, the Cyanidiophyceae red algae are the only photosynthetic eukaryotes able to live under extremely low pH (0-5) and relatively high temperature (35ºC to 63ºC). These extremophiles live as biofilms in the springs, inhabit acid soils near the hot springs, and form endolithic populations in the surrounding rocks. Cyanidiophyceae represent a remarkable source of knowledge about the evolution of extremophilic lifestyles and their genomes encode specialized enzymes that have applied uses. Here we review the evolutionary origin, taxonomy, genome biology, industrial applications, and use of Cyanidiophyceae as genetic models. Currently, Cyanidiophyceae comprise a single order (Cyanidiales), three families, four genera, and nine species, including the well-known Cyanidioschyzon merolae and Galdieria sulphuraria. These algae have small, gene-rich genomes that are analogous to those of prokaryotes they live and compete with. There are few spliceosomal introns and evidence exists for horizontal gene transfer as a driver of local adaptation to gain access to external fixed carbon and to extrude toxic metals. Cyanidiophyceae offer a variety of commercial opportunities such as phytoremediation to detoxify contaminated soils or waters and exploitation of their mixotrophic lifestyles to support the efficient production of bioproducts such as phycocyanin and floridosides. In terms of exobiology, Cyanidiophyceae are an ideal model system for understanding the evolutionary effects of foreign gene acquisition and the interactions between different organisms inhabiting the same harsh environment on the early Earth. Finally, we describe ongoing research with C. merolae genetics and summarize the unique insights they offer to the understanding of algal biology and evolution.
