Carbon-carbon bond formation and cleavage at redox active bis(pyridylimino)isoindole (BPI) germylene compounds.

Redox-active ligands provide alternative reaction pathways by facilitating redox events. Among these, tridentate bis(piridylimino)isoindole (BPI) fragments offer great potential, though their redox-active behaviour remains largely underdeveloped. We describe herein a family of BPI germanium(II) complexes and the study of their redox properties.

In the current study, we investigate the association of spp.

PHARMACOKINETICS OF CEFTAZIDIME IN SIGNAL CRAYFISH () FOLLOWING A SINGLE DOSE.

Crustaceans are housed in zoos and aquariums and have also gained importance in the private sector and food industry. Shell lesions are common and often attributed to bacterial infections. However, few controlled studies have been performed evaluating antibiotics in crustaceans.

Human airway epithelium controls infection via inducible nitric oxide synthase.

Introduction: Airway epithelial cells play a central role in the innate immune response to invading bacteria, yet adequate human infection models are lacking.

Methods: We utilized mucociliary-differentiated human airway organoids with direct access to the apical side of epithelial cells to model the initial phase of respiratory tract infection.

Results: Immunofluorescence of infected organoids revealed that invades the epithelial barrier and subsequently proliferates within the epithelial space.

Enhancement of Crystal Growth in Molten Salts by a Cocrystallization Agent: Synthesis and Luminescent Properties of Ce- and Eu-Doped La(SiS)I.

In this study, we present the growth of large (SiS)I ( = La, Ce) crystals, both undoped and doped with Ce and Eu. The synthesis process involves the utilization of an arc-melted precursor in conjunction with sulfur and KI. We investigate the role of Zr, Nb, Mo, and Ir as cocrystallization agents, facilitating the growth of relatively large (up to 6-7 mm) crystals.

Genetic barcodes for species identification and phylogenetic estimation in ghost spiders (Araneae: Anyphaenidae: Amaurobioidinae).

The identification of spider species presents many challenges, since in most cases the characters used are from genital structures that are only fully developed in the adult stage, hence the identification of immatures is most often not possible. Additionally, these structures usually also present some intra-specific variability, which in some cases makes the identification of closely related species difficult. The genetic barcode technique (DNA barcodes), based on sequencing of the mitochondrial marker cytochrome c oxidase subunit I (COI ), has proven a useful, complementary tool to overcome these limitations.

A low-coordinate platinum(0)-germylene for E-H bond activation and catalytic hydrodehalogenation.

Pairing transition metals and heavier tetrylenes (Si, Ge, Sn, Pb) holds great potential for cooperative bond activation and catalysis. In this work, we investigate the reactivity of a low-coordinate Pt(0)/Ge(II) system that emerges from the reaction between the monoligated platinum(0) precursor [(PMeAr)Pt(olefin)] with germylene dimer [ArGeCl] (where Ar = CH-2,6-(CH-2,6-Pr)). The resulting complex reveals ability for cooperative bond activation.

Is hyperactivity in children with attention deficit/hyperactivity disorder (ADHD) a functional response to demands on specific executive functions or cognitive demands in general?

Objective: Hyperactivity is a core and impairing deficit in the clinical model of attention-deficit/hyperactivity disorder (ADHD). However, the extent to which hyperactivity in ADHD is evoked by cognitively challenging tasks in general or by demands on specific executive functions remains unclear.

Method: A clinically evaluated and carefully phenotyped community-referred sample of 184 children ages 8-13 (M = 10.

Executive function deficits in attention-deficit/hyperactivity disorder and autism spectrum disorder.

Executive function deficits have been reported in both autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). However, little is known regarding which, if any, of these impairments are unique vs. shared in children with ADHD versus ASD.

The Effects of the COVID-19 Mask Mandate on Complication Rates in Postmastectomy Tissue Expansion.

Introduction: Tissue expansion is a commonly used breast reconstructive strategy. Although the procedure is regarded as safe, tissue expander to implant-based breast reconstruction is reported to have the highest rates of postoperative infection among plastic surgery operations. During the COVID-19 pandemic, face masks were required at all hospital facilities at our institution.

Temperature-dependent alterations in the proteome of the emergent fish pathogen Edwardsiella piscicida.

Edwardsiella piscicida is an emerging bacterial pathogen and the aetiological agent of edwardsiellosis among cultured and wild fish species globally. The increased frequency of outbreaks of this Gram-negative, facultative intracellular pathogen pose not only a threat to the aquaculture industry but also a possible foodborne/waterborne public health risk due to the ill-defined zoonotic potential. Thus, understanding the role of temperature on the virulence of this emerging pathogen is essential for comprehending the pathogenesis of piscine edwardsiellosis in the context of current warming trends associated with climate change, as well as providing insight into its zoonotic potential.

A review of latency in the Alloherpesviridae family.

The ability to impact the immune response of the host has been recognized as essential for the success of a virus during infection. A few groups of viruses can combine these immunomodulatory mechanisms with specific patterns of their own transcriptional and replication regulation to achieve persistence within the host long term. The Herpesvirales order is one of those groups and the resultant state is known as latency.

Comparative morphology of the rhinarium and upper lip in sigmodontine rodents: Refined nomenclature, intertribal variation in a phylogenetic framework, and functional inferences.

Rodents have received substantial attention in the study of olfaction. However, the rhinarium, the naked part of the nose, which plays an important role in chemical, tactile, and thermal perception, has been relatively overlooked. This study presents a comprehensive analysis of the rhinarium morphology and spatially associated structures (i.

Yeast Particle Encapsulation of Azole Fungicides for Enhanced Treatment of Azole-Resistant .

Addressing the growing problem of antifungal resistance in medicine and agriculture requires the development of new drugs and strategies to preserve the efficacy of existing fungicides. One approach is to utilize delivery technologies. Yeast particles (YPs) are 3-5 µm porous, hollow microspheres, a byproduct of food-grade yeast extract manufacturing processes and an efficient and flexible drug delivery platform.

Prophages carrying Zot toxins on different Vibrio genomes: A comprehensive assessment using multilayer networks.

Vibrios, a group of bacteria that are among the most abundant in marine environments, include several species such as Vibrio cholerae and Vibrio parahaemolyticus, which can be pathogenic to humans. Some species of Vibrio contain prophages within their genomes. These prophages can carry genes that code for toxins, such as the zonula occludens toxin (Zot), which contribute to bacterial virulence.

Frugal and Translatable [O]O Production for Human Inhalation with Direct Delivery from the Cyclotron to a Hybrid PET/MR.

Autism and sexual and gender minority identity in college students: Examination of self-reported rates, functional outcomes, and treatment engagement.

Autistic individuals and those who identify with a sexual and/or gender minority are both at risk for various mental health concerns and related impairments. However, the connection between autism and sexual and/or gender minorities and mental health and functional outcomes is not clear. Here, we provide evidence of these connections by analyzing data from a large nationally representative dataset from the American College Health Association-National College Health Assessment III.
