OHP-041 Formulary Decision-Making For Biosimilars: Considerations For Hospital Pharmacists
2013
Background It has been 6 years since the first biosimilar was approved for use in the European Union (EU). Given the likelihood that biosimilar monoclonal antibodies will be approved in Europe in the near future, it is timely to review the formulary selection criteria for biologicals and biosimilars. The European Medicines Agency (EMA) has issued guidelines that define the regulation of biosimilars in Europe and recommend approaches to establish biosimilarity. However, several questions regarding the assessment of biosimilars for formulary inclusion remain unanswered, including those related to manufacturing and drug supply. Purpose To aid hospital pharmacists in developing evaluation crite…
Psychological State after an Acute Coronary Syndrome: Impact of Physical Limitations
2021
The aim of this study was to investigate how physical limitations after ACS influence patients’ quality of life and health perception. This was a longitudinal clinical study. We recruited 146 patients diagnosed with ACS. The patients performed a stress test (Bruce’s protocol) for the evaluation of physical limitations and were classified according to the test result: without physical limitations (more than 10 METS), with some physical limitations (7 to 9 METS), and with high physical limitations (less than 6 METS). Significant differences were found between the three groups immediately after the diagnosis of ACS and after a period of three months, regarding health perception, anxiety, depre…
Want to Impact Physical, Technical, and Tactical Performance during Basketball Small-Sided Games in Youth Athletes? Try Differential Learning Beforeh…
2020
This study aimed to analyze the acute effect of small-sided games, based on differential learning, on the physical, technical, and positioning performance of young basketball players. Eight basketball players under 13 (U13) participated in this study. A total of eight sessions involving half-court small-sided games (4 sets ×
Resistance Training Acutely Impairs Agility and Spike-Specific Performance Measures in Collegiate Female Volleyball Players Returning from the Off-Se…
2020
This study examined the acute effects of resistance training (RT) on volleyball-specific performance. Sixteen female volleyball players undertook their initial, pre-season RT bout. Countermovement jump (CMJ), delayed onset of muscle soreness (DOMS), and sport-specific performances (i.e., run-up jump, agility, and spiking speed and accuracy) were measured before, 24 (T24), and 48 (T48) hours after RT. A significant increase in DOMS was observed at T24 and T48 (~207.6% ±
Targeting Acute Leukemia and Cancer by High-Affinity T-Cell-Receptor Transfer
2003
Accumulation and subsequent overexpression of human mdm2 (hdm2) and altered p53 protein is associated with high-level presentation of hdm2 and wild-type (wt) p53 derived peptides by major histocompatibility complex (MHC) class I molecules on a wide range of malignant cells. A major barrier to the design of broad-spectrum hdm2 and p53 specific immunotherapeutics for leukemia and cancer, however, has been the observation that low-level expression of hdm2 and wt p53 peptides by non-transformed tissues and cells results in self-tolerance of T-lymphocytes with high avidity for self-class I MHC / self-peptide complexes. Although the peripheral T-cell repertoire is mostly devoid of such high-avidi…
Biology and management of therapy-related acute promyelocytic leukemia.
2013
Therapy-related acute promyelocytic leukemia (t-APL) has been increasingly reported after exposure to cytotoxic and/or immunosuppressive agents given for prior malignancies or autoimmune diseases. t-APL represents both a model for better understanding human leukemogenesis and an interesting therapeutic subset which requires specific adaptations for optimal management.We discuss here potential risk factors for t-APL development and the main biologic and clinical characteristics of t-APL as compared to de-novo APL.In addition, we review therapeutic results obtained in patients with t-APL receiving conventional retinoic acid and chemotherapy and discuss new treatment opportunities with minimal…
Effects ofBacillus thuringiensisCry1Ab and Cry3Aa endotoxins on predatory Coleoptera tested through artificial diet-incorporation bioassays
2009
AbstractTraditional approaches to studying the effects of genetically modified (GM) crops on beneficial insects involve either field assays, comparing insect population levels between control and GM crops or tritrophic bioassays with contaminated insects – usually larvae or eggs of Lepidoptera – as preys. Here, we report the results of a bioassay using an artificial diet, suitable for predatory Coleoptera, to supplyBacillus thuringiensis(Bt) solubilized Cry1Ab and Cry3Aa as well as trypsin-activated Cry1Ab toAtheta coriariaandCryptolaemus montrouzieriadults and young larvae ofAdalia bipunctata. Water, solubilization buffer and trypsin-treated solubilization buffer were used as controls. In …
Production of Adenosine by Ectonucleotidases: A Key Factor in Tumor Immunoescape
2012
It is now well known that tumor immunosurveillance contributes to the control of cancer growth. Many mechanisms can be used by cancer cells to avoid the antitumor immune response. One such mechanism relies on the capacity of cancer cells or more generally of the tumor microenvironment to generate adenosine, a major molecule involved in antitumor T cell response suppression. Adenosine is generated by the dephosphorylation of extracellular ATP released by dying tumor cells. The conversion of ATP into adenosine is mediated by ectonucleotidase molecules, namely, CD73 and CD39. These molecules are frequently expressed in the tumor bed by a wide range of cells including tumor cells, regulatory T …
Psychiatric comorbidity in compulsive sexual behavior disorder (CSBD)
2020
This is a post-print version of the paper. To cite this article: Ballester-Arnal, R., Castro-Calvo, J., Giménez-García, C., Gil-Juliá, B. & Gil-Llario, M.D (2020). Psychiatric comorbidity in Compulsive Sexual Behavior Disorder (CSBD). Addictive Behaviors, 107, 106384. https://doi.org/10.1016/j.addbeh.2020.106384 Compulsive Sexual Behavior Disorder (CSBD) is characterized by a persistent failure to control intense and recurrent sexual impulses, urges, and/or thoughts, resulting in repetitive sexual behavior that causes a marked impairment in important areas of functioning. Data collected from clinical populations suggest that CSBD frequently co-occurs with other Axis I and II psychiatric dis…
The transcription factor NFATc2 controls IL-6–dependent T cell activation in experimental colitis
2008
The nuclear factor of activated T cells (NFAT) family of transcription factors controls calcium signaling in T lymphocytes. In this study, we have identified a crucial regulatory role of the transcription factor NFATc2 in T cell–dependent experimental colitis. Similar to ulcerative colitis in humans, the expression of NFATc2 was up-regulated in oxazolone-induced chronic intestinal inflammation. Furthermore, NFATc2 deficiency suppressed colitis induced by oxazolone administration. This finding was associated with enhanced T cell apoptosis in the lamina propria and strikingly reduced production of IL-6, -13, and -17 by mucosal T lymphocytes. Further studies using knockout mice showed that IL-…
