As multigene panel testing is becoming routine in clinical care, there are recommendations at national and international level, as to which genes should be analyzed in the context of a hereditary breast and ovarian cancer (HBOC). However, the individual composition of gene panels offered by testing laboratories vary, resulting in a different variant diagnostic rate. Therefore, we performed a retrospective NGS dataset analysis of suspected HBOC patients who had been tested at different German diagnostic laboratories that are part of the NASGE network.

Pathogenic variants in the leucine zipper-like transcriptional regulator 1 gene () have been identified in schwannomatosis and Noonan syndrome. Here, we expand the phenotype spectrum of variants. We identified four loss-of-function heterozygous variants in five children with multiple café au lait macules and one adult with multiple café au lait macules and axillar freckling, by applying gene panel analysis in four families.

Timely identification of fetal conditions enables comprehensive evaluation, counseling, postnatal planning, and prenatal treatments. This study assessed the existing evidence on how social determinants of health (SDOH) influence diagnosis timing of fetal conditions appropriate for care in fetal care centers (FCCs). Eligible studies were conducted in the U.

Background: Epilepsy is one of the most common and disabling neurological disorders. It is highly prevalent in children with neurodevelopmental delay and syndromic diseases. However, epilepsy can also be the only disease-determining symptom.

With the rapid growth of specialized fetal care centers (FCCs) across the United States, a new area of nursing practice has emerged. Fetal care nurses provide care in FCCs to pregnant persons experiencing complex fetal conditions. This article describes the unique practice of fetal care nurses necessitated by the complexity of perinatal care and the provision of maternal-fetal surgery in FCCs.

Background: A diet high in parent's own milk (parental milk) is a lifesaving intervention for critically ill infants. Lactating parents whose infants are born with birth defects that require surgical repair (surgical infants) shortly after birth often struggle to initiate and maintain a milk supply that meets their infant's nutritional needs. Antenatal milk expression has been identified as a safe, feasible, and potentially effective strategy that promotes parents' direct chest/breastfeeding or milk expression (lactation) confidence and helps parents attain their lactation goals.

Background/purpose: Although maternal-fetal surgery to treat fetal anomalies such as spina bifida continues to grow more common, potential health disparities in the field remain relatively unexamined. To address this gap, we identified maternal-fetal surgery studies with the highest level of evidence and analyzed the reporting of participant sociodemographic characteristics and representation of racial and ethnic groups.

Methods: We conducted a systematic review of the scientific literature using biomedical databases.

The increased risk of chemical warfare agent usage around the world has intensified the search for high-surface-area materials that can strongly adsorb and actively decompose chemical warfare agents. Dimethyl methylphosphonate (DMMP) is a widely used simulant molecule in laboratory studies for the investigation of the adsorption and decomposition behavior of sarin (GB) gas. In this paper, we explore how DMMP interacts with the as-synthesized mesoporous CeO.

[Nb(η-CHMe)] reacts with ethylenediamine (en) solutions of KGe in the presence of 18-crown-6 to give [(η-CHMe)NbHGe] () and [(η-CHMe)NbGeNb(η-CHMe)] () as their corresponding [K(18-crown-6)] salts. The crystalline solids are dark brown, air-sensitive, and sparingly soluble or insoluble in most solvents. The [K(18-crown-6)] salts of cluster ions and have been characterized by energy-dispersive X-ray (EDX) analysis, NMR studies, single-crystal X-ray diffraction, and electrospray ionization time-of-flight (ESI-TOF) mass spectrometry studies.

Cluster anions [Cp*RuPb] (1) and [Cu@Cp*RuPb] (2) represent the first vertex-substituted zintl icosahedra and 1 is the first non-centered zintl icosahedron isolated in the condensed phase. Complexes 1 and 2 are both 12-vertex, 26-electron closo-clusters with C point symmetry and are static on the Pb NMR time scale in solution.

Cerium oxide (ceria, CeO) is a technologically important material for energy conversion applications. Its activities strongly depend on redox states and oxygen vacancy concentration. Understanding the functionality of chemical active species and behavior of oxygen vacancy during operation, especially in high-temperature solid-state electrochemical cells, is the key to advance future material design.

Shear-wave elastography may produce misleadingly high values if too much pressure is applied during the imaging process. However, in clinical routine there is presently no way to monitor the pressure applied during the measurements. In this work we introduce a novel measurement setup which can directly be attached to an ultrasonic imaging transducer and allows observation of the applied pressure in real time.

Cohen syndrome (CS) is a rare, autosomal recessive disorder characterized by intellectual disability, postnatal microcephaly, facial abnormalities, abnormal truncal fat distribution, myopia, and pigmentary retinopathy. It is often considered an underdiagnosed condition, especially in children with developmental delay and intellectual disability. Here we report on four individuals from a large Jordanian family clinically diagnosed with CS.

A stable solid electrolyte interphase (SEI) has been proven to be a key enabler to most advanced battery chemistries, where the reactivity between the electrolyte and the anode operating beyond the electrolyte stability limits must be kinetically suppressed by such SEIs. The graphite anode used in state-of-the-art Li-ion batteries presents the most representative SEI example. Because of similar operation potentials between graphite and silicon (Si), a similar passivation mechanism has been thought to apply on the Si anode when using the same carbonate-based electrolytes.

Article Synopsis
  • The icosahedral clusters [M@Pb] (M=Co, Rh, Ir) were synthesized using specific precursors and characterized using X-ray crystallography, confirming their isostructural and isoelectronic relationships.
  • The clusters exhibit a unique 26-electron configuration with near-perfect icosahedral symmetry, resulting in significant downfield Pb NMR chemical shifts attributed to σ-aromaticity.
  • Computational DFT analysis indicates that the observed chemical shifts and J-couplings of Pb with M (Co, Rh, Ir) correlate well, with variations primarily driven by the chemical shift anisotropy tensor's orientation.

The importance of the solid-electrolyte interphase (SEI) for reversible operation of Li-ion batteries has been well established, but the understanding of its chemistry remains incomplete. The current consensus on the identity of the major organic SEI component is that it consists of lithium ethylene di-carbonate (LEDC), which is thought to have high Li-ion conductivity, but low electronic conductivity (to protect the Li/C electrode). Here, we report on the synthesis and structural and spectroscopic characterizations of authentic LEDC and lithium ethylene mono-carbonate (LEMC).

Molybdenum(VI) oxide (MoO) is used in a number of technical processes such as gas filtration and heterogeneous catalysis. In these applications, the adsorption and dissociation of water on the surface can influence the chemistry of MoO and thus the course of heterogeneous reactions. We use ambient pressure X-ray photoelectron spectroscopy to study the interaction of water with a stoichiometric MoO surface and a MoO surface that features oxygen defects and hydroxyl groups.

Reactions of KSi with the low-valent transition-metal complex Mo(CO)(CH) in ethylenediamine/toluene solutions in the presence of 2,2,2-cryptand yield the {Si(NHCHCHNH)[Mo(CO)]} dianion, which contains an octahedral Si(NHCHCHNH) subunit. The SiN core comprises a rare example of a doubly deprotonated ethylenediame ligand in a coordination complex and is also the first structurally characterized example of a homoleptic Si(N∩N) trischelate. Its structure and spectroscopic properties are described.

Performance of proton-solid oxide fuel cells (H-SOFC) is governed by ion transport through solid/gas interfaces. Major breakthroughs are then intrinsically linked to a detailed understanding of how parameters tailoring bulk proton conductivity affect surface chemistry in situ, at an early stage. In this work, we studied proton and oxygen transport at the interface between H-SOFC electrolyte BaCe ZrYO ( x = 0; 0.
