A new species of Rhadinoloricaria (Siluriformes: Loricariinae) from Colombia.

During 2009, photos of three specimens in poor conditions from the Caquetá River system in Colombia generated suspicions about the existence of a new species of Rhadinoloricaria. In 2022, additional specimens were obtained from the same aquatic system allowing confirm the new species presence. The new species has a projected, spatula-shaped snout, and a pattern of buccal ornamentation similar to that observed in R.

Establishment and inheritance of minichromosomes from Arabidopsis haploid induction.

Minichromosomes are small, sometimes circular, rearranged chromosomes consisting of one centromere and short chromosomal arms formed by treatments that break DNA, including plant transformation. Minichromosomes have the potential to serve as vectors to quickly move valuable genes across a wide range of germplasm, including into adapted crop varieties. To realize this potential, minichromosomes must be reliably generated, easily manipulated, and stably inherited.

Validation of a predictive model for bacteraemia (MPB5-Toledo) in the patients seen in emergency departments due to infections.

Objective: To validate a simple risk score to predict bacteremia (MPB5-Toledo) in patients seen in the emergency departments (ED) due to infections.

Methods: Prospective and multicenter observational cohort study of the blood cultures (BC) ordered in 74 Spanish ED for adults (aged 18 or older) seen from October 1, 2019, to February 29, 2020. The predictive ability of the model was analyzed with the area under the Receiver Operating Characteristic curve (AUC-ROC).

LD-CNV: rapid and simple discovery of chromosomal translocations using linkage disequilibrium between copy number variable loci.

Large-scale structural variations, such as chromosomal translocations, can have profound effects on fitness and phenotype, but are difficult to identify and characterize. Here, we describe a simple and effective method aimed at identifying translocations using only the dosage of sequence reads mapped on the reference genome. We binned reads on genomic segments sized according to sequencing coverage and identified instances when copy number segregated in populations.

Rare instances of haploid inducer DNA in potato dihaploids and ploidy-dependent genome instability.

In cultivated tetraploid potato (Solanum tuberosum), reduction to diploidy (dihaploidy) allows for hybridization to diploids and introgression breeding and may facilitate the production of inbreds. Pollination with haploid inducers (HIs) yields maternal dihaploids, as well as triploid and tetraploid hybrids. Dihaploids may result from parthenogenesis, entailing the development of embryos from unfertilized eggs, or genome elimination, entailing missegregation and the loss of paternal chromosomes.

Epigenetics dysfunction in morbid obesity with or without obstructive sleep apnoea: the EPIMOOSA study.

Background: Obstructive sleep apnoea (OSA) and morbid obesity (MO), defined by a body mass index ≥35 kg/m, are two closely related conditions. Recent studies suggest that circulating microRNA (miRNA) plays a potential role in the physiopathology of both conditions. To date, circulating miRNA expression has been studied separately in both conditions, but never jointly.

Fine-Scale Analysis of the Energy-Land-Water Nexus: Nitrate Leaching Implications of Biomass Cofiring in the Midwestern United States.

As scientists seek to better understand the linkages between energy, water, and land systems, they confront a critical question of scale for their analysis. Many studies exploring this nexus restrict themselves to a small area in order to capture fine-scale processes, whereas other studies focus on interactions between energy, water, and land over broader domains but apply coarse resolution methods. Detailed studies of a narrow domain can be misleading if the policy intervention considered is broad-based and has impacts on energy, land, and agricultural markets.

Genomic Outcomes of Haploid Induction Crosses in Potato ( L.).

The challenges of breeding autotetraploid potato () have motivated the development of alternative breeding strategies. A common approach is to obtain uniparental dihaploids from a tetraploid of interest through pollination with Andigenum Group (formerly ) cultivars. The mechanism underlying haploid formation of these crosses is unclear, and questions regarding the frequency of paternal DNA transmission remain.

Extra-pulmonary small cell carcinoma in the head and neck setting: the role of prophylactic cranial irradiation.

Head-and-neck small cell carcinoma (HN-SmCC) is a rare entity and there is limited data to support management decisions. The role of prophylactic cranial irradiation (PCI) remains controversial. A retrospective review of 21 consecutive HN-SmCCs was performed.

Progressive tumefactive fibroinflammatory lesion of the infratemporal fossa treated by radiation therapy.

Tumefactive fibroinflammatory lesion (TFIL) is a rare benign tumor in the head and neck region. We present a case of a 40-year-old female with a benign but progressive lesion of the infratemporal fossa, which was diagnosed as TFIL. Patient responded briefly to a course of steroid treatment but eventually showed progression and was unresponsive to further steroids.

Metabolic syndrome and coronary heart disease among Spanish male workers: a case-control study of MESYAS.

Background And Aims: In Spain, the incidence of coronary heart disease is below that expected based on the burden of classic cardiovascular risk factors present in the population. Whether the risk associated with metabolic syndrome is lower in Spain deserves to be investigated. This study evaluates the association of incident clinical coronary heart disease with metabolic syndrome and each of its individual defining components in a sample of Spanish working males.

Survival disparities in newborns with congenital diaphragmatic hernia: a national perspective.

Purpose: The aim of the study was to examine national outcomes for congenital diaphragmatic hernia (CDH).

Methods: We analyzed the Kids' Inpatient Database for patients admitted at less than 8 days of age.

Results: Overall, 2774 hospitalizations were identified.

Primary frozen section diagnosis by robotic microscopy and virtual slide telepathology: the University Health Network experience.

Although telepathology (TP) has not been widely implemented for primary frozen section diagnoses, interest in its use is growing as we move into an age of increasing sub-specialization and centralization of pathology services. University Health Network (UHN) is a 3-site academic institution in downtown Toronto. The pathology department is consolidated at its Toronto General Hospital (TGH) site.

Usefulness of triglycerides-to-high-density lipoprotein cholesterol ratio for predicting the first coronary event in men.

Overweight and obesity potentiate the development of cardiovascular risk factors but many doubts have arisen recently regarding their role in coronary events. We evaluated the predictive value of a surrogate maker of insulin resistance, the ratio of triglyceride (TG) to high-density lipoprotein (HDL), for the incidence of a first coronary event in men workers according to body mass index (BMI). We designed a case-control study of active subjects collected from a single factory through their annual health examination and medical reports.

Gender differences in obesity related cardiovascular risk factors in Spain.

Background: Obesity and overweight are increasing progressively leading to an increase in cardiovascular risk factors and cardiovascular events.

Methods: The MESYAS Registry (Metabolic Syndrome in Active Subjects) recruited active workers from their annual health examinations in Spain through 2003. Body mass index was used to diagnose overweight and obesity.

Comparison of serum lipid values in subjects with and without the metabolic syndrome.

Insulin resistance is supposed to be the basis of metabolic syndrome (MS), although it is difficult to measure. The ratio of triglyceride (TG) to high-density lipoprotein (HDL) has been proposed as a surrogate marker of insulin resistance in overweight subjects. The aim of the present study was to assess the accuracy of the TG/HDL ratio for the diagnosis of MS.

Cervical facet dislocation: techniques for ventral reduction and stabilization.

Object: To demonstrate the safety and utility of one surgical approach, the authors reviewed their experience with the ventral surgical approach for decompression, reduction, and stabilization in 10 patients with either unilateral or bilateral cervical facet dislocation.

Methods: Six patients presented with unilateral cervical facet dislocation and four patients with bilateral cervical facet dislocation. There were six male and four female patients who ranged in age from 17 to 72 years (average 37.
