Polymorphism of the Transcription Factor 7-Like 2 Gene (TCF7L2) Interacts with Obesity on Type-2 Diabetes in the PREDIMED Study Emphasizing the Heter…
2016
Nutrigenetic studies analyzing gene-diet interactions of the TCF7L2-rs7903146 C > T polymorphism on type-2 diabetes (T2D) have shown controversial results. A reason contributing to this may be the additional modulation by obesity. Moreover, TCF7L2-rs7903146 is one of the most influential variants in T2D-genetic risk scores (GRS). Therefore, to increase the predictive value (PV) of GRS it is necessary to first see whether the included polymorphisms have heterogeneous effects. We comprehensively investigated gene-obesity interactions between the TCF7L2-rs7903146 C > T polymorphism on T2D (prevalence and incidence) and analyzed other T2D-polymorphisms in a sub-sample. We studied 7018 PREDIMED …
Neoadjuvant Management of Early Breast Cancer: A Clinical and Investigational Position Statement
2019
AbstractBackgroundNeoadjuvant treatment is increasingly one of the preferred therapeutic options for early breast cancer and may have some unique outcomes, such as identifying predictive and prognostic factors of response or increasing the knowledge of individual tumor biology.DesignA panel of experts from different specialties reviewed published clinical studies on the neoadjuvant management of breast cancer. Recommendations were made that emphasized the clinical multidisciplinary management and the investigational leverage in early breast cancer.ResultsNeoadjuvant therapy has equivalent efficacy to adjuvant therapy, and it has some additional benefits that include increasing breast conser…
Systematic review and meta-analysis on targeted therapy in advanced pancreatic cancer
2015
Abstract Aim A systematic review and meta-analysis from literature has been performed to assess the impact of targeted therapy in advanced pancreatic cancer. Methods By searching different literature databases and major cancer meetings proceedings, data from all randomized clinical trials designed to investigate molecular targeted agents in the treatment of advanced pancreatic cancer were collected. The time-frame between January 2007 and March 2015 was selected. Data on predefined end-points, including overall survival, progression-free survival in terms of Hazard Ratio and response-rate were extracted and analyzed by a random effects model. Pooled data analysis was performed according to …
Three-dimensional multiple-particle tracking with nanometric precision over tunable axial ranges
2017
The precise localization of nanometric objects in three dimensions is essential to identify functional diffusion mechanisms in complex systems at the cellular or molecular level. However, most optical methods can achieve high temporal resolution and high localization precision only in two dimensions or over a limited axial (z) range. Here we develop a novel wide-field detection system based on an electrically tunable lens that can track multiple individual nanoscale emitters in three dimensions over a tunable axial range with nanometric localization precision. The optical principle of the technique is based on the simultaneous acquisition of two images with an extended depth of field while …
Multidisciplinary surgical management of Cowden syndrome: Report of a case
2016
Cowden’s Syndrome (CS) is a rare congenital autosomal dominant disorder that affects around 1/200000 patients with an incomplete penetrance and variable expressivity, characterized by alterations in a tumor suppressor gene. A 14-year-old Caucasian male patient came to the attention of the authors complaining of palm nodules, gingival bleeding and painful pedunculated lesions on the lips and on the labial side of anterior sextants. After genetic investigation the final diagnosis of a Cowden Syndrome was made. The lesions were surgically removed under general anesthesia and no clinical signs of recurrence were found three months after surgical excision. Considering the severe symptoms of the …
Substantial fat mass loss reduces low-grade inflammation and induces positive alteration in cardiometabolic factors in normal-weight individuals
2019
AbstractThe accumulation of fat, especially in visceral sites, is a significant risk factor for several chronic diseases with altered cardiometabolic homeostasis. We studied how intensive long-term weight loss and subsequent weight regain affect physiological changes, by longitudinally interrogating the lipid metabolism and white blood cell transcriptomic markers in healthy, normal-weight individuals. The current study examined 42 healthy, young (age: 27.5 ± 4.0 years), normal-weight (body mass index, BMI: 23.4 ± 1.7 kg/m2) female athletes, of which 25 belong to the weight loss and regain group (diet group), and 17 to the control group. Participants were evaluated, and fasting blood samples…
Association of Toll-like receptors 2, 3, and 4 genes polymorphisms with periapical pathosis risk
2016
Background: The aim of this study was to investigate the role of gene variations of Toll-like receptors (TLR) 2, 3, and 4 on genetic susceptibility to periapical pathosis. Material and Methods: One hundred patients were included in the study and divided into two groups as follows; Control Group (n=50) that have root canal treatment and no periapical lesion, Patient Group (n=50) that have root canal treatment and periapical lesion. TLR2 Arg753Gln, TLR3 (c.1377C/T) and TLR4 Asp299Gly and Thr399Ile polymorphisms were genotyped by using PCR-RFLP. Genotypical analysis of control and patient groups were investigated to disclose whether there is any association between periapical lesions and gene …
The role of registries in rare genetic lipid disorders: Review and introduction of the first global registry in lipoprotein lipase deficiency
2017
International audience; A good understanding of the natural history of rare genetic lipid disorders is a pre-requisite for successful patient management. Disease registries have been helpful in this regard. Lipoprotein Lipase Deficiency (LPLD) is a rare, autosomal-recessive lipid disorder characterized by severe hypertriglyceridemia and a very high risk for recurrent acute pancreatitis, however, only limited data are available on its natural course. Alipogene tiparvovec (Glybera (R)) is the first gene therapy to receive Marketing Authorization in the European Union; GENIALL (GENetherapy In the MAnagement of Lipoprotein Lipase Deficiency), a 15-year registry focusing on LPLD was launched in …
Bioactive extracts from persimmon waste: influence of extraction conditions and ripeness
2021
In this work, a bioactive persimmon extract was produced from discarded fruits. A central composite design was used to evaluate the effect of different extraction parameters and ripeness stages of persimmon fruits on the total phenolic content and antioxidant activity of the resulting extracts. Significantly greater phenolic contents were obtained from immature persimmon (IP) fruits. The optimum IP extract with the conditions set by the experimental design was industrially up-scaled and its composition and functional properties were evaluated and compared with those obtained under lab-scale conditions. Both extracts contained significant protein (>20%) and phenolic contents (∼11–27 mg GA/g …
European countries in the race to attract successful biopharma investment: Winners and laggers
2021
The post-coronavirus era will open myriad opportunities for the biopharma industry. However, the extent to which each country will take advantage of this promising new scenario will largely depend on its position in a few key areas. Here, we offer an overview of the European countries that are winning and those that are lagging behind in the race to attract the greatest investment in this industry and to attain the highest rate of successful new ventures. Our results highlight the vital importance of a sound, active funding base, especially in terms of venture capital. Our findings also suggests that general scientific foundations are not enough to secure an advantage in new venture formati…
