Forty different sample preparation methods were tested to obtain the most informative MALDI-TOF MS protein profiles of pork meat. Extraction by 25% formic acid with the assistance of zirconia-silica beads followed by defatting by methanol:chloroform mixture (1:1, v/v) and deposition by using the layer-by-layer method was determined as the optimum sample preparation protocol. The discriminatory power of the method was then examined on samples of pork meat and meat products. The method was able to discriminate between selected salami based on the production method and brand and was able to monitor the ripening process in salami...

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) has become the most frequent liver disease, closely related with metabolic risk factors such as obesity, insulin resistance, dyslipidemia, diabetes mellitus, and metabolic syndrome. In this context, γ-Glutamyl transpeptidase (GGT) and high-density lipoprotein cholesterol (HDL-C) have shown correlations with steatosis severity and metabolic syndrome, respectively. This positions the GGT/HDL-C ratio as a potential diagnostic indicator for NAFLD...

OBJECTIVE: The highly infiltrative growth of glioblastoma (GBM) makes distinction between the tumor and normal brain tissue challenging. Therefore, fluorescence-guided surgery is often used to improve visual identification of radiological tumor margins. The aim of this study was to evaluate the ability of recently developed molecularly targeted near-infrared (NIR) protease-activated probes to visualize GBM tissue and to compare the most promising candidate with the gold standard, 5-aminolevulinic acid (5-ALA)...

De novo variants in the NaV 1.2 voltage-gated sodium channel gene SCN2A are among the major causes of developmental and epileptic encephalopathies (DEE). Based on their biophysical impact on channel conductance and gating, SCN2A DEE variants can be classified into gain-of-function (GoF) or loss-of-function (LoF). Clinical and functional data have linked early seizure onset DEE to the GoF SCN2A variants, whereas late seizure onset DEE is associated with the loss of SCN2A function. This study aims to assess the impact of GoF and LoF SCN2A variants on cultured neuronal network activity and explore their modulation by selected antiseizure medications (ASM)...

Genetic selection has remarkably helped U.S. dairy farms to decrease their carbon footprint by more than doubling milk production per cow over time. Despite the environmental and economic benefits of improved feed and milk production efficiency, there is a critical need to explore phenotypical variance for feed utilization to advance the long-term sustainability of dairy farms. Feed is a major expense in dairy operations, and their enteric fermentation is a major source of greenhouse gases in agriculture. The challenges to expanding the phenotypic database, especially for feed efficiency predictions, and the lack of understanding of its drivers limit its utilization...

Small noncoding RNAs play an important role in various disease states, including cancer. PIWI proteins, a subfamily of Argonaute proteins, and PIWI-interacting RNAs (piRNAs) were originally described as germline-specific molecules that inhibit the deleterious activity of transposable elements. However, several studies have suggested a role for the piRNA-PIWI axis in somatic cells, including somatic stem cells. Dysregulated expression of piRNAs and PIWI proteins in human tumors implies that, analogously to their roles in undifferentiated cells under physiological conditions, these molecules may be important for cancer stem cells and thus contribute to cancer progression...

Nose reconstruction is challenging given the three-dimensional structure and free edge, and various methods have been reported. In general, local flaps provide cosmetic outcomes that are better than those following skin grafts, but there are no published comparative studies on Asians. To determine whether local flaps or skin grafts may optimally be used to reconstruct external nasal defects among Asians. We retrospectively collected data on patients who underwent external nasal tumour resection and reconstruction by 14 plastic surgeons in eight Japanese institutes from 2009 to 2021...

This closed cohort study aimed to identify the associations between dairy calf management practices and herd-level perinatal calf mortality risk. From February 2020 to June 2021, predominantly Holstein dairy farms in Québec (n = 1832) and New Brunswick (n = 52), Canada, registered in the dairy herd improvement program, were visited once. A questionnaire covering all aspects of precalving, calving, and colostrum management was administered. Data regarding perinatal mortality were retrieved from the dairy herd improvement program database for each farm for 2021...

The Rezūm system has emerged as a promising treatment option for benign prostatic hyperplasia (BPH) by employing endoscopic removal of prostate tissue. This meta-analysis aimed to evaluate the benefits and drawbacks of Rezūm therapy in recent studies. A systematic literature search was conducted in EMBASE, PubMed, and the Cochrane Library databases until December 2021, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The search utilized keywords such as water vapor thermal therapy, Rezūm, convective water vapor thermal therapy, and convective radiofrequency water vapor thermal therapy...

The production of plant-based dairy alternatives has been majorly focused on the improvement of sensorial, technological and nutritional properties, to be able to mimic and replace milk-based fermented products. The presence of off-flavours and antinutrients, the lack of production of dairy-like flavours or the metabolic inaccessibility of plant proteins are some of the challenges to overcome to generate plant-based dairy alternatives. However, in the present study, it is demonstrated how the synergistic effect of two LAB strains, when cocultured, can simultaneously solve those challenges when fermenting in four different plant-based raw materials: soy, pea, oat, and potato drinks (SPOP)...

Pentamethinium indolium salts are promising fluorescence probes and anticancer agents with high mitochondrial selectivity. We synthesized two indolium pentamethinium salts: a cyclic form with quinoxaline directly incorporated in the pentamethinium chain (cPMS) and an open form with quinoxaline substitution in the γ-position (oPMS). To better understand their properties, we studied their interaction with mitochondrial phospholipids (cardiolipin and phosphatidylcholine) by spectroscopic methods (UV-Vis, fluorescence, and NMR spectroscopy)...

Novel species of coagulase-negative staphylococci, which could serve as reservoirs of virulence and antimicrobial resistance factors for opportunistic pathogens from the genus Staphylococcus , are recognized in human and animal specimens due to advances in diagnostic techniques. Here, we used whole-genome sequencing, extensive biotyping, MALDI-TOF mass spectrometry, and chemotaxonomy to characterize five coagulase-negative strains from the Staphylococcus haemolyticus phylogenetic clade obtained from human ear swabs, wounds, and bile...

Salmonella Dublin (S. Dublin) is an emerging pathogen on dairy farms in Canada. In Ontario, S. Dublin has been increasingly isolated from diagnostic laboratory samples. The objective of this observational cross-sectional study was to identify management practices associated with herd positivity for S. Dublin. A convenience sample of 100 dairy farms was visited in Ontario, Canada from April to August 2022. Farms were visited once to collect blood samples from 20 heifers between 4 and 24 mo old, sample bulk tank milk, and administer an in-person questionnaire on management practices...

BACKGROUND: Cardiovascular diseases are responsible for the majority of deaths resulting from non-alcoholic fatty liver disease (NAFLD). NAFLD is associated with hypertension and this is a key predictor of severe liver outcomes and an indicator of nonspecific portal fibrosis. AIM: To assess the association between hypertension and NAFLD severity. METHODS: We conducted a secondary analysis of data from Peruvian adults with obesity and NAFLD who attended a Peruvian bariatric center...

BACKGROUND: Among the most recent methods to diagnose liver fibrosis is 2D shear wave elastography (2D-SWE). However, the evidence in the Latin population is limited, and there is no consensus on the cutoff points for each stage of fibrosis. AIM: To evaluate the diagnostic performance of 2D-SWE for liver fibrosis in adults with obesity who underwent bariatric surgery (BS). METHODS: We conducted a cross-sectional study on patients with obesity who underwent BS between 2020 and 2021...

Brain metastases are a very common and serious complication of oncological diseases. Despite the vast progress in multimodality treatment, brain metastases significantly decrease the quality of life and prognosis of patients. Therefore, identifying new targets in the microenvironment of brain metastases is desirable. Fibroblast activation protein (FAP) is a transmembrane serine protease typically expressed in tumour-associated stromal cells. Due to its characteristic presence in the tumour microenvironment, FAP represents an attractive theranostic target in oncology...

BACKGROUND: A growing body of literature shows that psychological distress is not only a major threat to psychological well-being but can also have a significant impact on physical health. In cancer patients, it can negatively affect prognosis and posttreatment recovery processes. Since face-to-face psychological interventions are often inaccessible to cancer patients, researchers have recently been focusing on the effectiveness of eHealth adaptations of well-established approaches. In this context, there has been a call for high-quality randomised controlled trials that would allow for a direct comparison of different approaches, potentially addressing different needs and preferences of patients, and also for more systematic research focusing on how psychological interventions affect not only psychological but also biological markers of stress...

Calf mortality can be used as an indicator of animal health and welfare in dairy farms. However, there are several challenges surrounding the estimation and reporting of this metric, specifically: (1) lack of records or reliable data, (2) how data are collected, and (3) inconsistencies in calculation and definition used. Therefore, despite its importance, the lack of consensus on a definition of calf mortality makes it difficult to compare mortality rates between dairy farms or studies. Monitoring factors associated with calf mortality is vital to create preventative strategies...
