Non-vitamin K oral anticoagulants (NOAC) and the risk of myocardial infarction: Differences between factor IIa and factor Xa inhibition?

Guidelines already recommend non-vitamin K oral anticoagulants (NOAC) over vitamin-K antagonists (VKA) for stroke prevention in patients with atrial fibrillation. However, recommendations are lacking with respect to which NOAC to use. At the moment, NOACs may employ two different molecular mechanisms: Factor IIa inhibition (dabigatran) and factor Xa inhibition (apixaban, edoxaban, rivaroxaban). The focus of this review is to compare and contrast potential differences between factor IIa- and factor Xa inhibi...

EGFR L792H and G796R: Two Novel Mutations Mediating Resistance to the Third-Generation Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor Osimertinib.

The third-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI) osimertinib has been approved in many countries to treat advanced non-small cell lung cancer (NSCLC) in patients with the EGFR T790M mutation. As the development of acquired resistance is inevitable, the mechanisms of such resistance must be urgently clarified.

The high-level basis of body adaptation.

Prolonged visual exposure, or 'adaptation', to thin (wide) bodies causes a perceptual aftereffect such that subsequently seen bodies appear wider (thinner) than they actually are. Here, we conducted two experiments investigating the effect of rotating the orientation of the test stimuli by 90° from that of the adaptor. Aftereffects were maximal when adapting and test bodies had the same orientation. When they differed, the axis of the perceived distortion changed with the orientation of the body. Experimen...

The effect of the source and dose of manganese on the performance, digestibility and distribution of selected minerals, redox, and immune status of turkeys.

The aim of this study was to determine the effect of various levels of manganese added to the diet of growing turkeys in the conventional form of MnO or in the form of NP-Mn2O3 nanoparticles on growth performance, absorption, and accumulation of Mn, Zn, and Cu, and antioxidant and immune status. The experiment was conducted on 1080 one-day-old Hybrid Converter turkeys randomly assigned to 6 groups with 10 replications, in a two-factor design with three dosages of manganese - 100, 50, and 10 mg/kg, and two s...

Synergistic effects of tumor necrosis factor-α and insulin-like growth factor-I on survival of human trophoblast-derived BeWo cell line.

Trophoblast survival is regulated by cytokines and growth factors. While the pharmacological levels (10-100 ng/mL) of tumor necrosis factor (TNF)- α affect trophoblasts survival in vitro, the effects of the physiological levels (1-10 pg/mL) of TNF-α remain unknown. We investigated the effects of the physiological levels of TNF-α on proliferation and apoptosis of human trophoblast cells by using BeWo cells. Insulin-like growth factor (IGF)-I is also a potent regulator of trophoblast survival and has b...

Fibroblast growth factor-2, but not the adipose tissue-derived stromal cells secretome, inhibits TGF-β1-induced differentiation of human cardiac fibroblasts into myofibroblasts.

Transforming growth factor-β1 (TGF-β1) is a potent inducer of fibroblast to myofibroblast differentiation and contributes to the pro-fibrotic microenvironment during cardiac remodeling. Fibroblast growth factor-2 (FGF-2) is a growth factor secreted by adipose tissue-derived stromal cells (ASC) which can antagonize TGF-β1 signaling. We hypothesized that TGF-β1-induced cardiac fibroblast to myofibroblast differentiation is abrogated by FGF-2 and ASC conditioned medium (ASC-CMed). Our experiments demonstra...

A Comparative Analysis of Electric and Radiofrequency Microneedling Devices on the Market.

Microneedling was first described in 1995 by Orentreich and Orentreich for the treatment of atrophic scars and wrinkles.1 The local injury induced by dermal penetration of microneedling causes release of growth factors such as transforming growth factor (TGF)-α, TGF-β, and platelet-derived growth factor (PDGF). This stimulates collagen and elastin fiber production as well as capillary formation, ultimately leading to tissue remodeling.2.

Adaptation of soil microbial growth to temperature: using a tropical elevation gradient to predict future changes.

Terrestrial biogeochemical feedbacks to the climate are strongly modulated by the temperature response of soil microorganisms. Tropical forests, in particular, exert a major influence on global climate because they are the most productive terrestrial ecosystem. We used an elevation gradient across tropical forest in the Andes (a gradient of 20°C mean annual temperature, MAT), to test whether soil bacterial and fungal community growth responses are adapted to long-term temperature differences. We evaluated ...

Fast Morphological Gallbladder Changes Triggered by a Hypercholesterolemic Diet.

Obesity is a worldwide epidemic problem, described as a risk factor for hepatic diseases, such as non-alcoholic fatty liver disease and other pathologies related to development of cholesterol crystals and cholesterol gallbladder stones. It has been reported that cholesterol overload may cause hepatic damage; however, little is known about the effects of an acute hypercholesterolemic diet on the gallbladder. The aim of this manuscript was to evaluate the impact of a cholesterol-rich diet on the gallbladder.

Wound fluid of rats fed protein-free diets delays wound healing through the suppression of the IGF-1/ERK(1/2) signaling pathway.

Adequate nutrition is required to maintain healthy skin integrity, and malnourished patients with poor protein diet often experience delayed wound healing. Understanding the cellular mechanisms of protein malnutrition will justify the importance of optimal protein diets in health and disease defense. Therefore in the present study, we examined the effects of changes in wound fluid composition and its function caused by protein malnutrition on wound healing. Rats were fed a control (CO; 20% protein) diet or ...

Pharmacodynamic modelling of resistance to epidermal growth factor receptor inhibition in brain metastasis mouse models.

Epidermal growth factor receptor (EGFR) is thought to play a role in the regulation of cell proliferation; with its activation stimulating tumour growth. EGFR inhibitors have shown promise in the treatment of cancer, particularly in non-small cell lung cancer, however, resistance is observed in the majority of patients. A tumour growth model was developed aiming to explain this resistance.

Effect of deoxynivalenol on growth performance, histological morphology, anti-oxidative ability and immune response of juvenile Pacific white shrimp, Litopenaeus vannamei.

A 5-weeks experiment was conducted to evaluate the effect of deoxynivalenol on growth performance, histological morphology, anti-oxidative ability and immune capacity of Litopenaeus vannamei. White shrimp (mean initial weight 1.02 g) were fed seven isonitrogenous diets, Diet 1 as the control, Diet 2-4 was supplemented with grade levels (250, 500 and 1000 μg kg) of deoxynivalenol (DON), Diet 5-7 were formulated to contain graded levels of contaminated wheat flour. Each diet was assigned to four tanks ...

Controlled release of dextrin-conjugated growth factors to support growth and differentiation of neural stem cells.

An essential aspect of stem cell in vitro culture and in vivo therapy is achieving sustained levels of growth factors to support stem cell survival and expansion, while maintaining their multipotency and differentiation potential. This study investigated the ability of dextrin (~74,000 g/mol; 27.8 mol% succinoylation) conjugated to epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF; or FGF-2) (3.9 and 6.7% w/w protein loading, respectively) to support the expansion and differentiatio...

Modelling the role of microbial p-cresol in colorectal genotoxicity.

A greater understanding of mechanisms explaining the interactions between diet and the gut microbiota in colorectal cancer is desirable. Genotoxic microbial metabolites present in the colon may be implicated in carcinogenesis and potentially influenced by diet.

In Exp. 1, a total of 448 male broiler chickens were used in a randomized complete block design with body weight as a blocking factor. Seven dietary treatments were prepared in a 3 × 2 + 1 factorial arrangement with inclusion of sand, diatomaceous e...

Effects of dietary yeast culture on growth performance, immune response and disease resistance of gibel carp (Carassius auratus gibelio CAS Ⅲ).

A 50-day feeding trial was carried out to evaluate the partial replacement of fishmeal by yeast culture (YC) on growth performance, immune response and resistance against Aeromonas hydrophila in gibel carp CAS Ⅲ (Carassius auratus gibelio). Four isonitrogenous and isoenergetic practical diets including a basal diet (the control diet containing 10% fish meal, D0) and three yeast culture diets (substituting 20%, 40%, 60% of the fishmeal in the basal diet, D20, D40 and D60, respectively) were formulated. Eac...

A minireview of E4BP4/NFIL3 in heart failure.

Heart failure (HF) remains a major cause of morbidity and mortality worldwide. The primary cause identified for HF is impaired left ventricular myocardial function, and clinical manifestations may lead to severe conditions like pulmonary congestion, splanchnic congestion, and peripheral edema. Development of new therapeutic strategies remains the need of the hour for controlling the problem of HF worldwide. Deeper insights into the molecular mechanisms involved in etiopathology of HF indicate the significan...

Effects of antibiotic (bacitracin), anticoccidial (narasin), and alternative (Bacillus subtilis and zinc) feed additives on growth performance, internal organ development, and intestinal morphology of commercial broilers with or without subclinical coccidia challenge were determined. A total of 1,344 1-day-old male Ross × Ross 708 broilers were randomly distributed into 12 treatments (6 diets × 2 challenge treatments, 8 replication pens/treatment) in 96 floor pens. The 6 dietary treatments were as follows...

Fibroblast Growth Factor 9 Suppresses Striatal Cell Death Dominantly Through ERK Signaling in Huntington's Disease.

Huntington's disease (HD) is a heritable neurodegenerative disorder, and there is no cure for HD to date. A type of fibroblast growth factor (FGF), FGF9, has been reported to play prosurvival roles in other neurodegenerative diseases, such as Parkinson's disease and Alzheimer's disease. However, the effects of FGF9 on HD is still unknown. With many similarities in the cellular and pathological mechanisms that eventually cause cell death in neurodegenerative diseases, we hypothesize that FGF9 might provide n...

Overexpression of transforming growth factor β induced factor homeobox 1 represses NPC1L1 and lowers markers of intestinal cholesterol absorption.

Transforming growth factor β induced factor homeobox 1 (TGIF1) is a transcriptional repressor that limits the response to transforming growth factor ß signaling and also represses transcription independent of this pathway. Recently, we found higher serum cholesterol levels and more hepatic lipid accumulation in mice lacking Tgif1, and showed that TGIF1 can repress the expression of Soat2, the gene encoding the cholesterol esterifying enzyme acyl-Coenzyme A:cholesterol acyltransferase 2. Although there is ...

High-fat diet disrupts bone remodeling by inducing local and systemic alterations.

A high-fat (HF) diet leads to detrimental effects on alveolar bone (AB); however, the mechanisms linking adiposity to bone loss are poorly understood. This study investigated if AB resorption induced by an HF diet is associated with the regulation of inflammatory gene expression and if adipocytes can directly interfere with osteoclastogenesis. We also evaluated the effects of diet restriction (DR) on bone phenotype. C57BL6/J mice were fed normal chow or an HF diet for 12 weeks. Samples of maxillae, femur, b...

High-fat diet exacerbates postoperative pain and inflammation in a sex-dependent manner.

Obesity is often associated with increased pain, but little is known about the effects of obesity and diet on postoperative pain. In this study, effects of diet and obesity were examined in the paw incision model, a preclinical model of postoperative pain. Long-Evans rats were fed high-fat diet (40% calories from butter fat) or low-fat normal chow. Male rats fed high-fat diet starting 6 weeks prior to incision (a diet previously shown to induce markers of obesity) had prolonged mechanical hypersensitivity a...

The Effect of Creep Feed intake and Starter Diet allowance on Piglets' Gut Structure and Growth Performance after Weaning.

Diets offered to lactating and weaned piglets are the most expensive diets within pig production; however, the effect of these diets on lifetime pig performance is inconsistent. The objective of the current study was to investigate the impact of creep feed consumption during lactation and different starter diet allowances on piglets' gut structure and lifetime growth performance. In total, 320 pigs and 80 pigs (Landrace × Large white) were used after weaning in a 2 × 2 factorial arrangement to study growt...
