The increasing global demand for food and the strong effect of climate change have forced animal science to advance regarding new methods of selection in search of more efficient animals in production systems. Feed consumption represents more than 70% of the costs of sheep farms, and more efficient animals can increase the farmers' profitability. One of the main measures of feed efficiency is estimated residual feed intake (RFI), created in 1963 by Robert Koch for estimation in cattle and later adapted for sheep...

OBJECTIVE: To explore the potential role of miR-449a as biomarker for laryngeal squamous cell carcinoma (LSCC), especially in the decision strategy of neck dissection (ND). METHODS: Each patient underwent total laryngectomy and bilateral ND (levels II-IV); during surgery, tissue samples of around 1 × 0.5 cm were extracted from both healthy tissue adjacent to the tumor and the visibly affected tumor tissue. The extraction of total RNA, encompassing miRNA, was performed using a mirVana PARIS kit...

Neonicotinoids are insecticides used worldwide in phytosanitary and biocidal products and veterinary pharmaceuticals. Recently, some restrictions and bans have been imposed due to their adverse effects on nontarget invertebrates, including pollinators. Although they may have direct and indirect effects on wild vertebrates, few studies have assessed exposure to these compounds in wild birds, so our knowledge remains limited. In the present pilot study we have assessed the prevalence of seven neonicotinoid insecticides and some of their metabolites in whole blood samples from 19 European roller (Coracias garrulus) nestlings and five adult common kestrels (Falco tinnunculus) in an area treated with neonicotinoids to control the palm weevil (Rynchophorus ferrugineus) in southeastern Spain...

We report the case of a 26-year-old woman who presented with a profound gait disturbance and total disability following a medial patellofemoral ligament (MPFL) reconstruction for recurrent patellar dislocation. It is common knowledge that patellar instability is associated with multiple risk factors, including but not limited to loss of the MPFL, trochlear dysplasia, patella alta, an abnormally placed tibial tuberosity on the tibia, quadriceps contracture, genu valgum, excess of femoral anteversion, excess of external tibial torsion, and foot pronation...

PURPOSE: Literature reviews outline minimally invasive approaches for abdominal diastasis in patients without skin excess. However, few surgeons are trained in endoscopic rectus sheath plication, and no simulated training programs exist for this method. This study aimed to develop and validate a synthetic simulation model for the training of skills in this approach under the Messick validity framework. METHODS: A cross-sectional study was carried out to assess the participants' previous level of laparoscopic/endoscopic skills by a questionnaire...

Appendicitis stands as the most common surgical emergency in pediatric populations. Despite the existence of numerous diagnostic biomarkers, their utility is constrained by limitations in cost-effectiveness, potentially leading to therapeutic delays. This research aims to determine the diagnostic accuracy of the derived neutrophil-to-lymphocyte ratio (dNLR) in appendicitis. Although its role in this context has been recently described, this is the first study to compare its performance against acute-phase reactants routinely employed in clinical practice...

BACKGROUND: The Essential Tremor Rating Assessment Scale (TETRAS) is a popular scale for essential tremor (ET), but its activities of daily living (ADL) and performance (P) subscales are based on a structured interview and physical exam. No patient-reported outcome (PRO) scale for ET has been developed according to US regulatory guidelines. OBJECTIVE: Develop and validate a TETRAS PRO subscale. METHODS: Fourteen items, rated 0-4, were derived from TETRAS ADL and structured cognitive interviews of 18 ET patients...

Hepatoblastoma is the most common hepatic neoplasm in children. However, its incidence is infrequent beyond age five. We present the case of a 15-year-old female diagnosed with metastatic hepatoblastoma during hospitalization for liver function deterioration. The patient presented with abdominal distension, jaundice, and other symptoms indicative of advanced disease. Imaging and biopsy confirmed stage IV epithelial hepatoblastoma with pulmonary metastases. This case underscores the importance of considering hepatoblastoma in older pediatric patients or young adults presenting with hepatic masses despite lacking traditional risk factors for liver malignancies...

Clostridioides difficile may have a negative impact on gut microbiota composition in terms of diversity and abundance, thereby triggering functional changes supported by the differential presence of genes involved in significant metabolic pathways, such as short-chain fatty acids (SCFA). This work has evaluated shotgun metagenomics data regarding 48 samples from four groups classified according to diarrhea acquisition site (community- and healthcare facility-onset) and positive or negative Clostridioides difficile infection (CDI) result...

BACKGROUND: ILUMIEN IV was the first large-scale, multicenter, randomized trial comparing optical coherence tomography (OCT)-guided versus angiography-guided stent implantation in patients with high-risk clinical characteristics and/or complex angiographic lesions. OBJECTIVE: Here, we aimed to specifically examine outcomes in the complex angiographic lesions subgroup. METHODS: From the original trial population (n=2487), high-risk patients without complex angiographic lesions were excluded (n=514)...

Informal artisanal and small-scale mining (ASM) continues to grow globally, raising both challenges and opportunities in terms of economic, social, and environmental impacts. The ASM literature explores the formalization and transfer of corporate social responsibility (CSR) practices from larger firms as the pathway to minimize negative impacts and maximize benefits. But we know very little about environmental and social responsibilities of informal mining operations (and informal economy actors in general, who are often portrayed as devoid of these responsibilities)...

GATA3 plays critical roles in the development and function of various tissues and organs throughout the body. Likewise, TGF-β signaling is critical for placental development and can interact with GATA3. We aimed to investigate the involvement of the multifunctional cytokine and transcription factor in trophoblast development. By using immunohistochemistry, we evaluated the localization and expression level of GATA3 and TGF-β in placentas at term of normal pregnancy and with pre-eclampsia. Up-regulation of both GATA3 and TGF-β was observed in pathological placentas, with localization in the villus epithelium (syncytiotrophoblast) stroma and decidua...

While the ecological role that Trichodesmium sp. play in nitrogen fixation has been widely studied, little information is available on potential specialized metabolites that are associated with blooms and standing stock Trichodesmium colonies. While a collection of biological material from a T. thiebautii bloom event from North Padre Island, Texas, in 2014 indicated that this species was a prolific producer of chlorinated specialized metabolites, additional spatial and temporal resolution was needed. We have completed these metabolite comparison studies, detailed in the current report, utilizing LC-MS/MS-based molecular networking to visualize and annotate the specialized metabolite composition of these Trichodesmium blooms and colonies in the Gulf of Mexico (GoM) and other waters...

INTRODUCTION: Limited data exist on long-term follow-up of severe aortic stenosis (SAS) patients who have undergone transcatheter aortic valve implantation (TAVI) with a new generation, balloon expandable Myval transcatheter heart valve (THV). Thus, we sought to investigate the performance and 2-year clinical outcome of the Myval THV system based on Valve Academic Research Consortium-3 (VARC-3) criteria. MATERIAL AND METHODS: A multi-centre, registry-based, observational study was conducted, which included 207 consecutive degenerative SAS patients, from Turkey ( n = 128), Italy ( n = 58), and Greece ( n = 21) (mean [standard deviation] 81 (7) years, 94 [45%] men; 73% NYHA III or IV; EuroSCORE II 5...

Canine leishmaniosis, caused by the protozoan parasite Leishmania infantum , is a cosmopolitan vector-borne zoonosis, transmitted principally by Phlebotomus perniciosus in Spain and Portugal, where it is considered an endemic disease. Ecoinformatics tools such as ecological niche models (ENM) have been successfully tested to model the distribution of the risk of infection of different parasitosis as they take into account environmental variables vital for their survival. The risk map proposed in this study combines the potential distribution of Ph...

UNLABELLED: This study investigated the effect of polyols erythritol, d-mannitol, and maltitol on the volatility of aroma compounds γ-butyrolactone, 3-methyl-1-butanol, and 2-phenylethanol in aqueous solution. Headspace solid-phase microextraction/gas chromatography and diffusion-ordered nuclear magnetic resonance techniques were used to obtain information on aroma-food matrix interaction. Results demonstrated that adding polyols at final low concentrations of 5% or 10% ( w /w) to an aqueous solution of 2-phenylethanol reduced the release of vapor-phase aromas, except in the case of 3-methyl-1-butanol, which was not affected by the presence of polyols in the liquid matrix...

OBJECTIVE: Pancreatic ductal adenocarcinoma (PDAC) has limited therapeutic options, particularly with immune checkpoint inhibitors. Highly chemoresistant 'stem-like' cells, known as cancer stem cells (CSCs), are implicated in PDAC aggressiveness. Thus, comprehending how this subset of cells evades the immune system is crucial for advancing novel therapies. DESIGN: We used the KPC mouse model ( LSL-KrasG12D/+ ; LSL-Trp53R172H/+ ; Pdx-1-Cre ) and primary tumour cell lines to investigate putative CSC populations...

INTRODUCTION: In light of the burden of traumatic brain injury (TBI) in children and the excessive number of unnecessary CT scans still being performed, new strategies are needed to limit their use while minimising the risk of delayed diagnosis of intracranial lesions (ICLs). Identifying children at higher risk of poor outcomes would enable them to be better monitored. The use of the blood-based brain biomarkers glial fibrillar acidic protein (GFAP) and ubiquitin carboxy-terminal hydrolase-L1 (UCH-L1) could help clinicians in this decision...

Human visual experience of objects comprises a combination of visual features, such as color, position, and shape. Spatial attention is thought to play a role in creating a coherent perceptual experience, integrating visual information coming from a given location, but the mechanisms underlying this process are not fully understood. Deficits of spatial attention in which this integration process does not occur normally, such as neglect, can provide insights regarding the mechanisms of spatial attention in visual object recognition...
