A Case of Pediatric Internal Hernia Heralded by Constipation.

Meckel's diverticulum (MD) is the most common gastrointestinal congenital anomaly of the small intestine. A small subset of patients with MD develops a mesodiverticular band (MDB), creating a snare-like opening and the potential for internal hernias (IHs). IHs are a known possible cause of small bowel obstructions and are most common in adults post bariatric surgery.

A dataset to train intrusion detection systems based on machine learning models for electrical substations.

The growing integration of Information and Communication Technology into Operational Technology environments in electrical substations exposes them to new cybersecurity threats. This paper presents a comprehensive dataset of substation traffic, aimed at improving the training and benchmarking of Intrusion Detection Systems (IDS) installed in these facilities that are based on machine learning techniques. The dataset includes raw network captures and flows from real substations, filtered and anonymized to ensure privacy.

These 11-vertex -rhodathiaborane chelates result from PPh ligand substitution at the rhodium center and a -to- structural cluster transformation driven by H loss. Treating compounds and with triflic acid (TfOH) leads to the formation of cationic clusters and .

Chirality at Metal in a Linear [Ag(NHC)] Complex: Stereogenic C-Ag-C Axis, Atropisomerism and Role of π-π Interactions.

Chirality at the metal center is a well-established concept, exemplified by numerous four- and six-coordinated complexes. Here, a pioneering example of linear chirality-at-metal is described: [Ag(NHC)] (NHC=N-heterocyclic carbene). In solution, stabilizing π-π interactions preserve the chiral information of the solid state.

Stereocontrol of Metal-Centred Chirality in Rhodium(III) and Ruthenium(II) Complexes with NN'P Ligand.

Rh(III) and Ru(II) complexes, [RhCl(κ-NN'P-L)][SbF] (1) and [RuCl(κ-NN'P-L)] (2), were synthesised using the tetradentate ligand L (L=N,N-bis[(pyridin-2-yl)methyl]-[2-(diphenylphosphino)phenyl]methanamine). In each case only one diastereomer is detected, featuring cis-disposed pyridine groups. The chloride ligand trans to pyridine can be selectively abstracted by AgSbF, with the ruthenium complex (2) reacting more readily at room temperature compared to the rhodium complex (1) which requires elevated temperatures.

Methods: A randomized trial was carried out at a Mexican hospital. GCs were isolated from 18 women with infertility undergoing assisted reproductive techniques (ART).

Dynamic Configuration on a Chiral-at-Rhodium Catalyst Featuring a Flexible Tetradentate Ligand.

The unique dynamic configuration of an enantioselective chiral-at-metal catalyst based on Rh(III) and a non-chiral tetradentate ligand is described and resolved. At room temperature, the catalyst undergoes a dynamic configuration process leading to the formation of two interconvertible metal-stereoisomers, remarkably without racemization. Density functional theory (DFT) calculations indicate that this metal-isomerization proceeds via a concerted transition state, which features a trigonal bipyramidal geometry stabilized by the tetradentate ligand.

The Synthesis, Characterization, and Fluxional Behavior of a Hydridorhodatetraborane.

The octahydridotriborate anion plays a crucial role in the field of polyhedral boron chemistry, facilitating the synthesis of higher boranes and the preparation of diverse transition metal complexes. Among the stable forms of this anion, CsBH (or (n-CH)N)[BH] have been identified. These salts serve as valuable precursors for the synthesis of metallaboranes, wherein the triborate anion acts as a ligand coordinating to the metal center.

External and gastrointestinal parasites of the black-faced ibis Theristicus melanopis (Pelecaniformes: Threskiornithidae) in the Los Ríos region, southern Chile.

The black-faced ibis, Theristicus melanopis, is considered a useful bird species for agricultural activity because it preys upon various invertebrate and vertebrate pests. Although it is a common species in Chile, limited information is available regarding its parasites. The main objective of this study was to recover the diversity of ectoparasites and gastrointestinal helminths in black-faced ibises living in the communes of Valdivia and Panguipulli, Los Ríos region.

Determinants of COVID-19 vaccine hesitancy among pregnant persons.

Background: Vaccines reduce the risk of contracting and developing complications from coronavirus disease 2019 (COVID-19). Pregnant people are at increased risk of disease-related complications but have a higher prevalence of vaccine hesitancy (VH) than their nonpregnant counterparts.

Objective: This study aimed to describe risk factors and COVID-19- and vaccine-related perspectives that lead to VH among pregnant people in Mexico to target strategies to increase vaccine acceptance in this population.

suPAR links a dysregulated immune response to tissue inflammation and sepsis-induced acute kidney injury.

Acute kidney injury (AKI) secondary to sepsis results in poor outcomes and conventional kidney function indicators lack diagnostic value. Soluble urokinase plasminogen activator receptor (suPAR) is an innate immune-derived molecule implicated in inflammatory organ damage. We characterized the diagnostic ability of longitudinal serum suPAR levels to discriminate severity and course of sepsis-induced AKI (SI-AKI) in 200 critically ill patients meeting Sepsis-3 criteria.

A Clinical Overview of Anorexia Nervosa and Overcoming Treatment Resistance.

Anorexia nervosa (AN) is a type of eating disorder that has been increasing in incidence and has been encountered more commonly by physicians in their daily practice. Both environmental and genetic risk factors paired along with a more susceptible neurobiology are at play in the emerging resistance to treatment in AN. Preoccupations with intense fear of weight gain, dietary restrictions, excessive exercise, and how the individual is perceived by society mixed with underlying psychopathology all further add to the issue.

Their derived solvate complexes [Rh(κ ,,',-L1)(Solv)][SbF] (Solv = NCMe, 2; HO, 3) are resolved into their two enantiomers. Complexes 2 and 3 catalyze the Diels-Alder (DA) reaction between methacrolein and cyclopentadiene and the 1,3-dipolar cycloaddition reaction between methacrolein and the nitrone -benzylidenphenylamine--oxide.

Scalable Query Answering Under Uncertainty to Neuroscientific Ontological Knowledge: The NeuroLang Approach.

Researchers in neuroscience have a growing number of datasets available to study the brain, which is made possible by recent technological advances. Given the extent to which the brain has been studied, there is also available ontological knowledge encoding the current state of the art regarding its different areas, activation patterns, keywords associated with studies, etc. Furthermore, there is inherent uncertainty associated with brain scans arising from the mapping between voxels-3D pixels-and actual points in different individual brains.
