is an invasive hydrozoan found globally in freshwater habitats. has a complex life cycle that includes benthic, pelagic, dispersal and dormant stages. The distribution of the medusa (jellyfish) stage has been well documented, but little is known about the other life cycle stages, which are suggested to be more widespread.

Demonstrating multi-benefits of green infrastructure to schools through collaborative approach.

Green infrastructure (GI) is known to reduce road air pollution exposure, but their implementation in schools and associated benefits remain under-researched. In this study, two GI solutions, green screen and green gate, were co-designed and installed at a primary school in Guildford using collaborative and participatory methods. By assessing changes in air pollution levels, noise, and public perception before and after GI installation, we aimed to understand their impact on reducing children's exposure and evaluate other co-benefits.

Genitourinary cancer and family: The reverberating psychological and cardiovascular effects of a genitourinary cancer diagnosis on first-degree relatives and spouses.

Background: The psychological and cardiovascular health impacts on family members of patients who have been diagnosed with cancer have not been well characterized. The purpose of this study is to determine whether a family member's cancer diagnosis influences the risk of psychological illness and cardiovascular disease in first-degree relatives and spouses of patients affected by cancer.

Methods: This retrospective cohort analysis evaluated the risk of psychological illness and cardiovascular disease in first-degree relatives and spouses of patients diagnosed with a genitourinary cancer between 1990 and 2015 compared to relatives of those not diagnosed with a genitourinary cancer.

The genome of the colonial hydroid reveals that their stem cells use a toolkit of evolutionarily shared genes with all animals.

is a colonial marine hydroid that shows remarkable biological properties, including the capacity to regenerate its entire body throughout its lifetime, a process made possible by its adult migratory stem cells, known as i-cells. Here, we provide an in-depth characterization of the genomic structure and gene content of two species, and , placing them in a comparative evolutionary framework with other cnidarian genomes. We also generated and annotated a single-cell transcriptomic atlas for adult male and identified cell-type markers for all major cell types, including key i-cell markers.

Cnidofest 2022: hot topics in cnidarian research.

The second annual Cnidarian Model Systems Meeting, aka "Cnidofest", took place in Davis, California from 7 to 10th of September, 2022. The meeting brought together scientists using cnidarians to study molecular and cellular biology, development and regeneration, evo-devo, neurobiology, symbiosis, physiology, and comparative genomics. The diversity of topics and species represented in presentations highlighted the importance and versatility of cnidarians in addressing a wide variety of biological questions.

Coevolution of the Tlx homeobox gene with medusa development (Cnidaria: Medusozoa).

Cnidarians display a wide diversity of life cycles. Among the main cnidarian clades, only Medusozoa possesses a swimming life cycle stage called the medusa, alternating with a benthic polyp stage. The medusa stage was repeatedly lost during medusozoan evolution, notably in the most diverse medusozoan class, Hydrozoa.

Chromosome-level genome assembly of Hydractinia symbiolongicarpus.

Hydractinia symbiolongicarpus is a pioneering model organism for stem cell biology, being one of only a few animals with adult pluripotent stem cells (known as i-cells). However, the unavailability of a chromosome-level genome assembly has hindered a comprehensive understanding of global gene regulatory mechanisms underlying the function and evolution of i-cells. Here, we report the first chromosome-level genome assembly of H.

Internal hernia with volvulus after major abdominal reconstructions in pediatric urology - An infrequently reported and potentially devastating complication.

Introduction: Enterocystoplasty (EC), appendico- or ileovesicostomy (APV), and appendicocecostomy (APC) can facilitate continence and prevent renal damage for patients with congenital urologic or bowel disease. Bowel obstruction is a well-documented complication of these procedures, and the etiology of obstruction is variable. The aim of this study is to determine the incidence and describe the presentation, surgical findings, and outcomes of bowel obstruction from internal herniation due to these reconstructions.

Localization of Multiple Jellyfish Toxins Shows Specificity for Functionally Distinct Polyps and Nematocyst Types in a Colonial Hydrozoan.

is a colonial hydrozoan that displays a division of labor through morphologically distinct and functionally specialized polyp types. As with all cnidarians, their venoms are housed in nematocysts, which are scattered across an individual. Here, we investigate the spatial distribution of a specific protein family, jellyfish toxins, in which multiple paralogs are differentially expressed across the functionally specialized polyps.

The Phylogenetic Position of the Enigmatic, Polypodium hydriforme (Cnidaria, Polypodiozoa): Insights from Mitochondrial Genomes.

Polypodium hydriforme is an enigmatic parasite that belongs to the phylum Cnidaria. Its taxonomic position has been debated: whereas it was previously suggested to be part of Medusozoa, recent phylogenomic analyses based on nuclear genes support the view that P. hydriforme and Myxozoa form a clade called Endocnidozoa.

Venom system variation and the division of labor in the colonial hydrozoan .

Cnidarians (jellyfish, hydroids, sea anemones, and corals) possess a unique method for venom production, maintenance, and deployment through a decentralized system composed of different types of venom-filled stinging structures called nematocysts. In many species, nematocyst types are distributed heterogeneously across functionally distinct tissues. This has led to a prediction that different nematocyst types contain specific venom components.

Encrusters maintain stable carbonate production despite temperature anomalies among two inshore island reefs of the Pilbara, Western Australia.

Encrusting reef organisms such as crustose coralline algae (CCA), serpulid worms, bivalves, bryozoans, and foraminifera (collectively termed encrusters) provide essential ecosystem services and are a critical part of the reef framework. Globally, research into in situ growth and carbonate production of encrusters has focused on clear water fore-reef settings in the Pacific and Caribbean, with limited studies being conducted on marginal reef systems or within the Indian Ocean. Here we examined spatial and temporal variation in CCA coverage (%) and total encruster carbonate production rates (g cm yr) across two inshore turbid island reefs of northern Western Australia.

Phylogenetic and Selection Analysis of an Expanded Family of Putatively Pore-Forming Jellyfish Toxins (Cnidaria: Medusozoa).

Many jellyfish species are known to cause a painful sting, but box jellyfish (class Cubozoa) are a well-known danger to humans due to exceptionally potent venoms. Cubozoan toxicity has been attributed to the presence and abundance of cnidarian-specific pore-forming toxins called jellyfish toxins (JFTs), which are highly hemolytic and cardiotoxic. However, JFTs have also been found in other cnidarians outside of Cubozoa, and no comprehensive analysis of their phylogenetic distribution has been conducted to date.

Post-hypospadias urethrocutaneous fistulae: no difference in repair success between proximal and distal fistulae.

Unlabelled: INTRODUCTION Urethrocutaneous fistulae are the most common complication after hypospadias repair. We sought to compare outcomes of proximal versus distal urethrocutaneous fistula repair and hypothesized that patients with proximal fistulae would have lower rates of success than those with distal fistulae. We also aimed to evaluate factors that affected these outcomes.

Quality improvement education in surgical specialty training: A comparison of Vascular Surgery resident and Urology Resident experiences and attitudes.

Background: Academic institutions have increasingly focused on educating physicians and surgeons in concepts of value-based care, including quality improvement (QI). The extent to which QI curricular competencies are addressed in specialty surgical residency training is unclear.

Utilization of Radiographic Imaging for Infant Hydronephrosis over the First 12 Months of Life.

Purpose: The workup and surveillance strategies for infant hydronephrosis (HN) vary, although this could be due to grade-dependent differences in imaging intensity. We aimed to describe the frequency of imaging studies for HN within the first year of life, stratified by initial HN grade, within a large regional healthcare system. .

The evolution and development of coloniality in hydrozoans.

Hydrozoan colonies display a variety of shapes and sizes including encrusting, upright, and pelagic forms. Phylogenetic patterns reveal a complex evolutionary history of these distinct colony forms, as well as colony loss. Within a species, phenotypic variation in colonies as a response to changing environmental cues and resources has been documented.

Continence outcomes following a modification of the Mitchell bladder neck reconstruction in myelomeningocele: A single institution experience.

Background: Many surgical procedures have been developed to improve continence in myelomeningocele patients. Our modification of the Mitchell bladder neck reconstruction involves removal of a diamond-shaped wedge of the anterior bladder neck, tubularization of the bladder neck and urethra to increase outlet resistance, and addition of a bladder neck autologous fascial sling.

Objective: We aimed to evaluate rates of continence and re-operation in children with myelomeningocele undergoing this Modified Mitchell bladder neck reconstruction.

Experiences With Quality Improvement in Training: A National Survey of Urology Residents.

Objective: To determine the quality improvement (QI) experiences of urology residents in the United States.

Materials And Methods: An Institutional Review Board approved national survey of Urology residents was administered in June 2019. The survey instrument sought to understand QI curricular methods and experiences of urology residents as well as their knowledge of QI fundamentals.

Frizzled3 expression and colony development in hydractiniid hydrozoans.

Hydractiniid hydrozoan colonies are comprised of individual polyps connected by tube-like stolons or a sheet-like mat. Mat and stolons function to integrate the colony through continuous epithelia and shared gastrovascular cavity. Although mechanisms of hydrozoan polyp development have been well studied, little is known about the signaling processes governing the patterning of colonies.

CTL Clonotypes with Higher TCR Affinity Have Better Ability to Reduce the HIV Latent Reservoir.

The success of the shock and kill strategy for the HIV cure depends both on the reactivation of the latent reservoir and on the ability of the immune system to eliminate infected cells. As latency reversal alone has not shown any impact in the size of the latent reservoir, ensuring that effector CTLs are able to recognize and kill HIV-infected cells could contribute to reservoir reduction. In this study, we investigated which functional aspects of human CTLs are associated with a better capacity to kill HIV-infected CD4 T cells.

The effect of 1-day multidisciplinary clinic on breast cancer treatment.

Purpose: A delay in breast cancer treatment is associated with inferior survival outcomes; however, no clear guidelines exist defining the appropriate time frame from diagnosis to definitive treatment of breast cancer. A multidisciplinary approach for breast cancer treatment can minimize the time from diagnosis to first treatment. We hypothesized single-day multidisciplinary clinic (MDC) may accelerate the time to first treatment on complex breast cancer cases at our institution.

A cnidarian parasite of salmon (Myxozoa: ) lacks a mitochondrial genome.

Although aerobic respiration is a hallmark of eukaryotes, a few unicellular lineages, growing in hypoxic environments, have secondarily lost this ability. In the absence of oxygen, the mitochondria of these organisms have lost all or parts of their genomes and evolved into mitochondria-related organelles (MROs). There has been debate regarding the presence of MROs in animals.
