Molecular insights and novel approaches for targeting tumor metastasis
2020
In recent years, due to the effective drug delivery and preciseness of tumor sites or microenvironment, the targeted drug delivery approaches have gained ample attention for tumor metastasis therapy. The conventional treatment approaches for metastasis therapy have reported with immense adverse effects because they exhibited maximum probability of killing the carcinogenic cells along with healthy cells. The tumor vasculature, comprising of vasculogenic impressions and angiogenesis, greatly depends upon the growth and metastasis in the tumors. Therefore, various nanocarriers-based delivery approaches for targeting to tumor vasculature have been attempted as efficient and potential approaches…
A Case of Cardiomyopathy Due to Premature Ductus Arteriosus Closure: The Flip Side of Paracetamol.
2017
Paracetamol (acetaminophen or N-acetyl-p-aminophenol) is considered a safe analgesic and antipyretic nonsteroidal antiinflammatory drug commonly used during pediatric ages and during pregnancy. We report on a term neonate with closed ductus arteriosus, severe cardiomyopathy, right ventricular dysfunction, and functional stenosis of pulmonary arteries at birth after maternal self-medication with paracetamol and consumption of polyphenol-rich foods in late pregnancy. This drug, especially when associated with other vasoconstrictors (such as polyphenols), interferes with prostaglandin metabolism, which seriously accentuates the intrauterine ductus arteriosus constriction and leads to pharmacol…
The type of GnRH analogue used during controlled ovarian stimulation influences early embryo developmental kinetics: a time-lapse study
2013
OBJECTIVE: To explore if the GnRH analogue used for controlled ovarian stimulation (COS) and the ovulation triggering factor (GnRH agonist + hCG triggering versus GnRH antagonist + GnRH agonist triggering) affect embryo development and kinetics.STUDY DESIGN: In a retrospective cohort study in the Instituto Valenciano de Infertilidad (IVI) Alicante and the Instituto Universitario-IVI Valencia, Spain, 2817 embryos deriving from 400 couples undergoing oocyte donation were analysed. After controlled ovarian stimulation and IVF/intracytoplamic sperm injection, the timing of embryonic cleavages was assessed by a video time-lapse system. The results were analysed using Student's t test for compari…
Maternal nutrition and fetal growth: the role of iron status and intake during pregnancy
2012
Correspondence: Clara L RodriguezBernal Centro Superior de Investigacion en Salud Publica, Avenida Cataluna 21, Valencia 46020, Spain Tel +34 961 925 909 Fax +34 961 925 703 Email rodriguez_claber@gva.es Abstract: Fetal growth restriction is an important predictor of infant mortality and morbidity. Maternal iron status and iron supplementation during pregnancy have been related to fetal growth with contrasting results. Therefore, indication of iron supplementation, doses, and timing is still controversial. Current literature was reviewed in PubMed/MEDLINE using the following terms: “iron” or “iron deficiency” or “anemia” or “iron intake” or “iron supplementation” and “pregnancy” or “materna…
Syntaxin13 expression is regulated by mammalian target of rapamycin (mTOR) in injured neurons to promote axon regeneration.
2014
Injured peripheral neurons successfully activate intrinsic signaling pathways to enable axon regeneration. We have previously shown that dorsal root ganglia (DRG) neurons activate the mammalian target of rapamycin (mTOR) pathway following injury and that this activity enhances their axon growth capacity. mTOR plays a critical role in protein synthesis, but the mTOR-dependent proteins enhancing the regenerative capacity of DRG neurons remain unknown. To identify proteins whose expression is regulated by injury in an mTOR-dependent manner, we analyzed the protein composition of DRGs from mice in which we genetically activated mTOR and from mice with or without a prior nerve injury. Quantitati…
Intralipotherapy, the State of the Art.
2016
Background: Reconstruction intralipotherapy is a term commonly used in the field of aesthetic medicine, above all in Europe, which defines a specific injection technique developed for the treatment of localized fat with substances that provoke the lysis of adipocytes by means of an injection directly into the adipose tissue with a long needle. The aim of this study is to define the technique in detail and everything that is associated with it, on the basis of years of multicenter experience by doctors who perform it. Materials and Methods: From January 2010 to December 2014, 3,080 European physicians were trained in intralipotherapy technique, and approximately 152,500 patients were treated…
Fractional exhaled nitric oxide as a predictor of response to inhaled corticosteroids in patients with non-specific respiratory symptoms and insignif…
2017
Chronic non-specific respiratory symptoms are difficult to manage. This trial aimed to evaluate the association between baseline fractional exhaled nitric oxide (FeNO) and the response to inhaled corticosteroids in patients with non-specific respiratory symptoms.In this double-blind randomised placebo-controlled trial, we enrolled undiagnosed patients, aged 18-80 years, with cough, wheeze, or dyspnoea and less than 20% bronchodilator reversibility across 26 primary care centres and hospitals in the UK and Singapore. Patients were assessed for 2 weeks before being randomly assigned (1:1) to 4 weeks of treatment with extrafine inhaled corticosteroids (QVAR 80 μg, two puffs twice per day, equi…
Anti-muscarinic drugs as preventive treatment of exercise-induced bronchoconstriction (EIB) in children and adults.
2020
Regular physical activity is strongly recommended to prevent chronic respiratory diseases, including asthma. On the other hand, vigorous physical training may trigger airway symptoms and bronchoconstriction. The transient airway narrowing occurring because of exercise is named exercise-induced bronchoconstriction (EIB). Despite management according to guidelines, a significant proportion of patients experiences uncontrolled EIB, which thus represents a relevant unmet medical need. In particular, although prevention and treatment of EIB are effectively based on the use of beta-2 bronchodilator drugs, high heterogeneity in individual responses has been reported. Furthermore, even though beta-…
Effectiveness of omalizumab in patients 50 years and older with severe persistent allergic asthma.
2010
Omalizumab is approved for the treatment of severe allergic asthma.To compare the efficacy of omalizumab therapy in patients 50 years or older with patients younger than 50 years.Between November 2005 and November 2007 a total of 174 asthma patients 50 years or older (40.7% male, 51.1% taking oral corticosteroids, and mean [SD] serum IgE level of 315 [353] U/L) and 297 asthma patients younger than 50 years (40.0% male, 50.5% taking oral corticosteroids, and mean [SD] serum IgE level of 363 [431] U/L) who met the European Union criteria for add-on therapy with anti-IgE were treated prospectively with omalizumab for 4 months as part of 2 postmarketing surveillance trials.Compared with the pre…
Omalizumab provides long-term control in patients with moderate-to-severe allergic asthma.
2002
The ability of omalizumab, an anti-immnoglobulin-E agent, to maintain long-term disease control in patients with moderate-to-severe allergic asthma was investigated in a 24-week double-blind extension to a 28-week core trial. During the extension, 483 of the initial 546 patients were maintained on randomised treatment and the lowest sustainable dose of beclomethasone dipropionate (BDP) as established during the steroid-reduction phase of the core trial. The use of concomitant asthma medication was permitted and investigators were allowed to adjust the BDP dose or switch patients from BDP to other asthma medications if deemed necessary. More omalizumab-treated patients (33.5%) than placebo-t…
