    2014-09-28

    This review covers water-soluble polymer-drug conjugates and macromolecules that possess biological activity without attached low molecular weight drugs. The main design principles of traditional and backbone degradable polymer-drug conjugates as well as the development of a new paradigm in nanomedicines - (low molecular weight) drug-free macromolecular therapeutics are discussed. To address the biological features of cancer, macromolecular therapeutics directed to stem/progenitor cells and the tumor microenvironment are deliberated. Finally, the future perspectives of the field are briefly debated. Copyright © 2014 Elsevier B.V. All rights reserved.

  2. Therapeutic Nanodevices

    Lee, Stephen; Ruegsegger, Mark; Barnes, Philip; Smith, Bryan; Ferrari, Mauro

    Therapeutic nanotechnology offers minimally invasive therapies with high densities of function concentrated in small volumes, features that may reduce patient morbidity and mortality. Unlike other areas of nanotechnology, novel physical properties associated with nanoscale dimensionality are not the raison d'être of therapeutic nanotechnology, whereas the aggregation of multiple biochemical (or comparably precise) functions into controlled nanoarchitectures is. Multifunctionality is a hallmark of emerging nanotherapeutic devices, and multifunctionality can allow nanotherapeutic devices to perform multistep work processes, with each functional component contributing to one or more nanodevice subroutine such that, in aggregate, subroutines sum to a cogent work process. Cannonical nanotherapeutic subroutines include tethering (targeting) to sites of disease, dispensing measured doses of drug (or bioactive compound), detection of residual disease after therapy and communication with an external clinician/operator. Emerging nanotherapeutics thus blur the boundaries between medical devices and traditional pharmaceuticals. Assembly of therapeutic nanodevices generally exploits either (bio)material self-assembly properties or chemoselective bioconjugation techniques, or both. Given the complexity, composition, and the necessity for their tight chemical and structural definition inherent in the nature of nanotherapeutics, their cost of goods (COGs) might exceed that of (already expensive) biologics. Early therapeutic nanodevices will likely be applied to disease states which exhibit significant unmet patient need (cancer and cardiovascular disease), while application to other disease states well-served by conventional therapy may await perfection of nanotherapeutic design and assembly protocols.

    The use of ultrasound in medicine is now quite commonplace, especially with the recent introduction of small, portable and relatively inexpensive, hand-held diagnostic imaging devices. Moreover, ultrasound has expanded beyond the imaging realm, with methods and applications extending to novel therapeutic and surgical uses. These applications broadly include: tissue ablation, acoustocautery, lipoplasty, site-specific and ultrasound mediated drug activity, extracorporeal lithotripsy, and the enhancement of natural physiological functions such as wound healing and tissue regeneration. A particularly attractive aspect of this technology is that diagnostic and therapeutic systems can be combined to produce totally non-invasive, imageguided therapy. This general lecture will review a number of these exciting new applications of ultrasound and address some of the basic scientific questions and future challenges in developing these methods and technologies for general use in our society. We shall particularly emphasize the use of High Intensity Focused Ultrasound (HIFU) in the treatment of benign and malignant tumors as well as the introduction of acoustic hemostasis, especially in organs which are difficult to treat using conventional medical and surgical techniques.

    Therapeutic vaccines aim to control chronic HIV infection and eliminate the need for lifelong antiretroviral therapy (ART). Therapeutic HIV vaccine is being pursued as part of a functional cure for HIV/AIDS. We have outlined a basic protocol for inducing new T cell immunity during chronic HIV-1...... infection directed to subdominant conserved HIV-1 epitopes restricted to frequent HLA supertypes. The rationale for selecting HIV peptides and adjuvants are provided. Peptide subunit vaccines are regarded as safe due to the simplicity, quality, purity, and low toxicity. The caveat is reduced immunogenicity...

    1987-01-01

    Whether a radiopharmaceutical has diagnostic or therapeutic application depends on both the isotope and pharmaceutical used. For diagnostic applications, the isotope should undergo only γ-decay, since usually only γ-radiation is detected by nuclear medicine cameras. The half-life should be just long enough to allow the procedure to be performed. In contrast, the isotope needed for therapeutic purposes should have particulate radiation, such as a β-particle (electron), since these are locally absorbed an increase the local radiation dose. γ-Radiation, which penetrates the tissues, produces less radiation dose than do Β-particles. Several references dealing with radioactive decay, particulate interactions, and diagnostic and therapeutic applications of radiopharmaceuticals are available. Radiopharmaceuticals can legally be used only by physicians who are qualified by specific training in the safe handling of radionuclides. The experience and training of these physicians must be approved by the Nuclear Regulatory Commission or Agreement State Agency authorized to license the use of radiopharmaceuticals. A list of all byproduct material and procedures is available in the Code of Federal Regulations. Of the many radiopharmaceuticals available for diagnostic and therapeutic use, only those commonly used are discussed in this chapter

  8. PYTHIOSIS: A THERAPEUTIC APPROACH

    2015-10-01

    Full Text Available Pythiosis, a disease caused by the oomycete Pythium insidiosum, often presents inefficient response to chemotherapy. It is a consensus that, in spite the several therapeutic protocols, a combination of surgery, chemotherapy and immunotherapy should be used. Surgical excision requires the removal of the entire affected area, with a wide margin of safety. The use of antifungal drugs has resulted in variable results, both in vitro and in vivo, and presents low therapeutic efficiency due to differences in the agent characteristics, which differ from true fungi. Immunotherapy is a non-invasive alternative for the treatment of pythiosis, which aims at modifying the immune response of the host, thereby producing an effective response to the agent. Photodynamic therapy has emerged as a promising technique, with good activity against P. insidiosum in vitro and in vivo. However, more studies are necessary to increase the efficiency of the current treatment protocols and consequently improve the cure rates. This paper aims to conduct a review covering the conventional and recent therapeutic methods against P. insidiosum infections

    Full Text Available Stroke is significant cause of morbidity and mortality caused by disruption of blood flow. Neural injury occurs with two stage; while primary neural injury occurs with disruption of blood flow, after days and hours with metabolic processes secondary injury develops in tissues which is non injured in the first stage. Therefore it is important to prevent and treat the secondary injury as much as preventing and treating the primary neural injury. In this article developing pathophysiological changes after stroke, mechanisms of therapeutic hypothermia, application methods, the factors that determine the effectiveness, side effects and complications were reviewed.

    Koo, Seok Hwee; Lee, Edmund Jon Deoon

    2006-01-01

    1. Pharmacogenetics refers to the study of genetically controlled variations in drug response. Functional variants caused by single nucleotide polymorphisms (SNPs) in genes encoding drug-metabolising enzymes, transporters, ion channels and drug receptors have been known to be associated with interindividual and interethnic variation in drug response. Genetic variations in these genes play a role in influencing the efficacy and toxicity of medications. 2. Rapid, precise and cost-effective high-throughput technological platforms are essential for performing large-scale mutational analysis of genetic markers involved in the aetiology of variable responses to drug therapy. 3. The application of a pharmacogenetics approach to therapeutics in general clinical practice is still far from being achieved today owing to various constraints, such as limited accessibility of technology, inadequate knowledge, ambiguity of the role of variants and ethical concerns. 4. Drug actions are determined by the interplay of several genes encoding different proteins involved in various biochemical pathways. With rapidly emerging SNP discovery technological platforms and widespread knowledge on the role of SNPs in disease susceptibility and variability in drug response, the pharmacogenetics approach to therapeutics is anticipated to take off in the not-too-distant future. This will present profound clinical, economic and social implications for health care.

    Graves, David

    2015-09-01

    In this talk, I address research directed towards biomedical applications of atmospheric pressure plasma such as sterilization, surgery, wound healing and anti-cancer therapy. The field has seen remarkable growth in the last 3-5 years, but the mechanisms responsible for the biomedical effects have remained mysterious. It is known that plasmas readily create reactive oxygen species (ROS) and reactive nitrogen species (RNS). ROS and RNS (or RONS), in addition to a suite of other radical and non-radical reactive species, are essential actors in an important sub-field of aerobic biology termed ``redox'' (or oxidation-reduction) biology. It is postulated that cold atmospheric plasma (CAP) can trigger a therapeutic shielding response in tissue in part by creating a time- and space-localized, burst-like form of oxy-nitrosative stress on near-surface exposed cells through the flux of plasma-generated RONS. RONS-exposed surface layers of cells communicate to the deeper levels of tissue via a form of the ``bystander effect,'' similar to responses to other forms of cell stress. In this proposed model of CAP therapeutics, the plasma stimulates a cellular survival mechanism through which aerobic organisms shield themselves from infection and other challenges.

    Nuclear transfer and therapeutic cloning have widespread and attractive prospects in animal agriculture and biomedical applications. We reviewed that the quality of oocytes and nuclear reprogramming of somatic donor cells were the main reasons of the common abnormalities in cloned animals and the low efficiency of cloning and showed the problems and outlets in therapeutic cloning, such as some basic problems in nuclear transfer affected clinical applications of therapeutic cloning. Study on isolation and culture of nuclear transfer embryonic stem (ntES) cells and specific differentiation of ntES cells into important functional cells should be emphasized and could enhance the efficiency. Adult stem cells could help to cure some great diseases, but could not replace therapeutic cloning. Ethics also impeded the development of therapeutic cloning. It is necessary to improve many techniques and reinforce the research of some basic theories, then somatic nuclear transfer and therapeutic cloning may apply to agriculture reproduction and benefit to human life better.

    Full text: It is generally agreed that current focus of nuclear medicine development should be on molecular imaging and therapy. Though, the widespread use of the terminology 'molecular imaging' is quite recent, nuclear medicine has used molecular imaging techniques for more than 20 years ago. A variety of radiopharmaceuticals have been introduced for the internal therapy of malignant and inflammatory lesions in nuclear medicine. In the field of bio/medical imaging, nuclear medicine is one of the disciplines which has the privilege of organized and well developed chemistry/ pharmacy section; radio-chemistry/radiopharmacy. Fundamental principles have been developed more than 40 years ago and advanced research is going well into postgenomic era. The genomic revolution and dramatically increased insight in the molecular mechanisms underlying pathology have led to paradigm shift in drug development. Likewise does in the nuclear medicine. Here, the author will present current clinical and pre-clinical therapeutic radiopharmaceuticals based on molecular targets such as membrane-bound receptors, enzymes, nucleic acids, sodium iodide symporter, etc, in correlation with fundamentals of radiopharmacy.

    A brief outline of stem cells, stem cell therapy and therapeutic cloning is given. The position of therapeutic cloning with regard to other embryonic manipulations - IVF-based reproduction, embryonic stem formation from IVF embryos and reproductive cloning - is indicated. The main ethically challenging stages in therapeutic cloning are considered to be the nuclear transfer process including the source of eggs for this and the destruction of an embryo to provide stem cells for therapeutic use. The extremely polarised nature of the debate regarding the status of an early human embryo is noted, and some potential alternative strategies for preparing immunocompatible pluripotent stem cells are indicated

    2003-01-01

    Nuclear transfer technology can be applied to produce autologous differentiated cells for therapeutic purposes, a concept termed therapeutic cloning. Countless articles have been published on the ethics and politics of human therapeutic cloning, reflecting the high expectations from this new opportunity for rejuvenation of the aging or diseased body. Yet the research literature on therapeutic cloning, strictly speaking, is comprised of only four articles, all in the mouse. The efficiency of derivation of embryonic stem cell lines via nuclear transfer is remarkably consistent among these reports. However, the efficiency is so low that, in its present form, the concept is unlikely to become widespread in clinical practice. PMID:12949262

  2. Purinergic Signalling: Therapeutic Developments

    2017-09-01

    Full Text Available Purinergic signalling, i.e., the role of nucleotides as extracellular signalling molecules, was proposed in 1972. However, this concept was not well accepted until the early 1990’s when receptor subtypes for purines and pyrimidines were cloned and characterised, which includes four subtypes of the P1 (adenosine receptor, seven subtypes of P2X ion channel receptors and 8 subtypes of the P2Y G protein-coupled receptor. Early studies were largely concerned with the physiology, pharmacology and biochemistry of purinergic signalling. More recently, the focus has been on the pathophysiology and therapeutic potential. There was early recognition of the use of P1 receptor agonists for the treatment of supraventricular tachycardia and A2A receptor antagonists are promising for the treatment of Parkinson’s disease. Clopidogrel, a P2Y12 antagonist, is widely used for the treatment of thrombosis and stroke, blocking P2Y12 receptor-mediated platelet aggregation. Diquafosol, a long acting P2Y2 receptor agonist, is being used for the treatment of dry eye. P2X3 receptor antagonists have been developed that are orally bioavailable and stable in vivo and are currently in clinical trials for the treatment of chronic cough, bladder incontinence, visceral pain and hypertension. Antagonists to P2X7 receptors are being investigated for the treatment of inflammatory disorders, including neurodegenerative diseases. Other investigations are in progress for the use of purinergic agents for the treatment of osteoporosis, myocardial infarction, irritable bowel syndrome, epilepsy, atherosclerosis, depression, autism, diabetes, and cancer.

    The recognition of periodontal diseases as amenable to local antibiotherapy has resulted in a paradigmatic shift in treatment modalities of dental afflictions. Moreover the presence of antimicrobial resistance, surfacing of untoward reactions owing to systemic consumption of antibiotics has further advocated the use of local delivery of physiologically active substances into the periodontal pocket. While antimicrobials polymerized into acrylic strips, incorporated into biodegradable collagen and hollow permeable cellulose acetate fibers, multiparticulate systems, bio-absorbable dental materials, biodegradable gels/ointments, injectables, mucoadhesive microcapsules and nanospheres will be more amenable for direct placement into the periodontal pockets the lozenges, buccoadhesive tablets, discs or gels could be effectively used to mitigate the overall gingival inflammation. Whilst effecting controlled local delivery of a few milligram of an antibacterial agent within the gingival crevicular fluid for a longer period of time, maintaining therapeutic concentrations such delivery devices will circumvent all adverse effects to non- oral sites. Since the pioneering efforts of Goodson and Lindhe in 1989, delivery at gingival and subgingival sites has witnessed a considerable progress. The interest in locally active systems is evident from the patents being filed and granted. The present article shall dwell in reviewing the recent approaches being proffered in the field. Patents as by Shefer, et al.

    2003-01-01

    Full Text Available Trichomoniasis is frequent, parasitic and sexually transmitted infection of genitourinary tract. It is treated by metronidazole (5-nitroimidazole according to protocol recommended by Center for Disease Control (CDC formerly called: Communicable Disease Center [19]. The resistance of Trichomonas vaginalis (TV strains to metronidazole (MND was described in USA in 1960, and later on in many European countries [8, 9, 10, 11, 12, 13]. In these cases, due to persistent trichomonas infection, it is necessary to repeat MND treatment with moderate modification of dose and/or length of its application. Nevertheless, oncogenic and toxic effects of MND have to be taken into consideration. OBJECT The aim of this study was to investigate and analyze the incidence of TV in STD and lower susceptibility of certain TV strains to MND were analyzed. MATERIAL AND METHODS In three-year period (1999-2001 612 patients (244 females and 368 males suspected of STD were examined clinically and microbiologically at the Institute of Dermatovenereology in Belgrade. The patients detected for TV were treated according to CDC protocol. The affected were considered cured if there was no manifest clinical infection, and no TV verified by microbiological test. Results TV was isolated in 216 patients (35.29 % of all subjects. Trichomonas infection was found in 90 (36.88 % out of 244 tested females and in 126 (32.34 % of 368 males. Clinically manifested infection, with extensive urethral and vaginal secretion, was recorded in 161 patients, while the asymptomatic form was found in 55 subjects. This result indicates the predominance of manifested trichomonas infections (75.54 % of cases. The difference of distribution of clinical forms of trichomoniasis, in relation to sex, was not statistically significant (c2=0.854; p>0.05. The patients with verified trichomonas infection were treated by metronidazole according to CDC protocol. The recommended therapeutical scheme consisted of three

    This review aims to emphasize how therapeutic inertia, the failure of clinicians to intensify treatment when blood pressure rises or remains above therapeutic goals, contributes to suboptimal blood pressure control in hypertensive populations. Studies reveal that the therapeutic inertia is quite common and contributes to suboptimal blood pressure control. Quality improvement programs and standardized approaches to support antihypertensive treatment intensification are ways to combat therapeutic inertia. Furthermore, programs that utilize non-physician medical professionals such as pharmacists and nurses demonstrate promise in mitigating the effects of this important problem. Therapeutic inertia impedes antihypertensive management and requires a broad effort to reduce its effects. There is an ongoing need for renewed focus and research in this area to improve hypertension control.

    Inhale, in colaboration with Pfizer and Aventis Pharma (formerly Hoechst Marion Roussel; HMR), is developing an insulin formulation utilizing its pulmonary delivery technology for macromolecules for the potential treatment of type I and II diabetes. By July 2001, the phase III program had been completed and the companies had begun to assemble data for MAA and NDA filings; however, it was already clear at this time that additional data might be required for filing. By December 2001, it had been decided that the NDA should include an increased level of controlled, long-term pulmonary safety data in diabetic patients and a major study was planned to be completed in 2002, with the NDA filed thereafter (during 2002). US-05997848 was issued to Inhale Therapeutic Systems in December 1999, and corresponds to WO-09524183, filed in February 1995. Equivalent applications have appeared to date in Australia, Brazil, Canada, China, Czech Republic, Europe, Finland, Hungary, Japan, Norway, New Zealand, Poland and South Africa. This family of applications is specific to pulmonary delivery of insulin. In February 1999, Lehman Brothers gave this inhaled insulin a 60% probability of reaching market, with a possible launch date of 2001. The analysts estimated peak sales at $3 billion in 2011. In May 2000, Aventis predicted that estimated peak sales would be in excess of $1 billion. In February 2000, Merrill Lynch expected product launch in 2002 and predicted that it would be a multibillion-dollar product. Analysts Merril Lynch predicted, in September and November 2000, that the product would be launched by 2002, with sales in that year of e75 million, rising to euro 500 million in 2004. In April 2001, Merrill Lynch predicted that filing for this drug would occur in 2001. Following the report of the potential delay in regulatory filing, issued in July 2001, Deutsche Banc Alex Brown predicted a filing would take place in the fourth quarter of 2002 and launch would take place in the first

  7. Human Factor in Therapeutic Relationship

    Directory of Open Access Journals (Sweden)

    Ramazan Akdogan

    2011-03-01

    Full Text Available herapeutic relationship is a professional relationship that has been structured based on theoretical props. This relationship is a complicated, wide and unique relationship which develops between two people, where both sides' personality and attitudes inevitably interfere. Therapist-client relationship experienced through transference and counter transference, especially in psychodynamic approaches, is accepted as the main aspect of therapeutic process. However, the approaches without dynamic/deterministic tendency also take therapist-client relationship into account seriously and stress uniqueness of interaction between two people. Being a person and a human naturally sometimes may negatively influence the relationship between the therapist and client and result in a relationship going out of the theoretical frame at times. As effective components of a therapeutic process, the factors that stem from being human include the unique personalities of the therapist and the client, their values and their attitude either made consciously or subconsciously. Literature has shown that the human-related factors are too effective to be denied in therapeutic relationship process. Ethical and theoretical knowledge can be inefficient to prevent the negative effects of these factors in therapeutic process at which point a deep insight and supervision would have a critical role in continuing an acceptable therapeutic relationship. This review is focused on the reflection of some therapeutic factors resulting from being human and development of counter transference onto the therapeutic process.

    Prevention of COPD requires appropriate patient education, especially of adolescents, as well as the establishment of an effective national health policy. The new GOLD guidelines represent the current standard of knowledge on the management of chronic, progressive, obstructive pulmonary diseases. It points out that COPD is avoidable and treatable,and hence, there is no reason for therapeutic nihilism. Chronic bronchitis preceding a progressive respiratory obstruction cannot be improved with the presently available respiratory therapeutics. For this reason, therapeutic measures concentrate on the avoidance of exacerbations, which are primarily responsible for the severity of the course of COPD.

    Experimental evidence and clinical experience show that hypothermia protects the brain from damage during ischaemia. There is a growing hope that the prevention of fever in stroke will improve outcome and that hypothermia may be a therapeutic option for the treatment of stroke. Body temperature...... obvious therapeutic potential, hypothermia as a form of neuroprotection for stroke has been investigated in only a few very small studies. Therapeutic hypothermia is feasible in acute stroke but owing to serious side-effects--such as hypotension, cardiac arrhythmia, and pneumonia--it is still thought...

    The major challenge in the treatment of patients with advanced lethal prostate cancer is therapeutic resistance to androgen-deprivation therapy (ADT) and chemotherapy. Overriding this resistance requires understanding of the driving mechanisms of the tumor microenvironment, not just the androgen receptor (AR)-signaling cascade, that facilitate therapeutic resistance in order to identify new drug targets. The tumor microenvironment enables key signaling pathways promoting cancer cell survival ...

  14. Potential therapeutic applications of biosurfactants.

    Gudiña, Eduardo J; Rangarajan, Vivek; Sen, Ramkrishna; Rodrigues, Lígia R

    2013-12-01

    Biosurfactants have recently emerged as promising molecules for their structural novelty, versatility, and diverse properties that are potentially useful for many therapeutic applications. Mainly due to their surface activity, these molecules interact with cell membranes of several organisms and/or with the surrounding environments, and thus can be viewed as potential cancer therapeutics or as constituents of drug delivery systems. Some types of microbial surfactants, such as lipopeptides and glycolipids, have been shown to selectively inhibit the proliferation of cancer cells and to disrupt cell membranes causing their lysis through apoptosis pathways. Moreover, biosurfactants as drug delivery vehicles offer commercially attractive and scientifically novel applications. This review covers the current state-of-the-art in biosurfactant research for therapeutic purposes, providing new directions towards the discovery and development of molecules with novel structures and diverse functions for advanced applications.

    2013-03-01

    Full Text Available Since the discovery of RNA interference (RNAi, excitement has grown over its potential therapeutic uses. Targeting RNAi pathways provides a powerful tool to change biological processes post-transcriptionally in various health conditions such as cancer or autoimmune diseases. Optimum design of shRNA, siRNA, and miRNA enhances stability and specificity of RNAi-based approaches whereas it has to reduce or prevent undesirable immune responses or off-target effects. Recent advances in understanding pathogenesis of autoimmune diseases have allowed application of these tools in vitro as well as in vivo with some degree of success. Further research on the design and delivery of effectors of RNAi pathway and underlying molecular basis of RNAi would warrant practical use of RNAi-based therapeutics in human applications. This review will focus on the approaches used for current therapeutics and their applications in autoimmune diseases, including rheumatoid arthritis and Sjögren’s syndrome.

  17. Reactor-produced therapeutic radioisotopes

    International Nuclear Information System (INIS)

    Knapp, F.F. Jr.

    2002-01-01

    The significant worldwide increase in therapeutic radioisotope applications in nuclear medicine, oncology and interventional cardiology requires the dependable production of sufficient levels of radioisotopes for these applications (Reba, 2000; J. Nucl. Med., 1998; Nuclear News, 1999; Adelstein and Manning, 1994). The issues associated with both accelerator- and reactor-production of therapeutic radioisotopes is important. Clinical applications of therapeutic radioisotopes include the use of both sealed sources and unsealed radiopharmaceutical sources. Targeted radiopharmaceutical agents include those for cancer therapy and palliation of bone pain from metastatic disease, ablation of bone marrow prior to stem cell transplantation, treatment modalities for mono and oligo- and polyarthritis, for cancer therapy (including brachytherapy) and for the inhibition of the hyperplastic response following coronary angioplasty and other interventional procedures (For example, see Volkert and Hoffman, 1999). Sealed sources involve the use of radiolabeled devices for cancer therapy (brachytherapy) and also for the inhibition of the hyperplasia which is often encountered after angioplasty, especially with the exponential increase in the use of coronary stents and stents for the peripheral vasculature and other anatomical applications. Since neutron-rich radioisotopes often decay by beta decay or decay to beta-emitting daughter radioisotopes which serve as the basis for radionuclide generator systems, reactors are expected to play an increasingly important role for the production of a large variety of therapeutic radioisotopes required for these and other developing therapeutic applications. Because of the importance of the availability of reactor-produced radioisotopes for these applications, an understanding of the contribution of neutron spectra for radioisotope production and determination of those cross sections which have not yet been established is important.

    Strong, Tom; Busch, Robbie; Couture, Shari

    2008-07-01

    Family therapists' participation in therapeutic dialogue with clients is typically informed by evidence of how such dialogue is developing. In this article, we propose that conversational evidence, the kind that can be empirically analyzed using discourse analyses, be considered a contribution to widening psychotherapy's evidence base. After some preliminaries about what we mean by conversational evidence, we provide a genealogy of evaluative practice in psychotherapy, and examine qualitative evaluation methods for their theoretical compatibilities with social constructionist approaches to family therapy. We then move on to examine the notion of accomplishment in therapeutic dialogue given how such accomplishments can be evaluated using conversation analysis. We conclude by considering a number of research and pedagogical implications we associate with conversational evidence.

    2014-02-01

    The therapeutic use of cannabis has generated a lot of interest in the past years, leading to a better understanding of its mechanisms of action. Countries like the United States and Canada have modified their laws in order to make cannabinoid use legal in the medical context. It's also the case in France now, where a recent decree was issued, authorizing the prescription of medication containing "therapeutic cannabis" (decree no. 2013-473, June 5, 2013). Cannabinoids such as dronabinol, Sativex and nabilone have been tested for the treatment of acute and chronic pain. These agents are most promising to relieve chronic pain associated with cancer, with human immunodeficiency virus infection and with multiple sclerosis. However, longer-term studies are required to determine potential long-term adverse effects and risks of misuse and addiction.

    Full Text Available Therapeutic dancing has been advocated as an effective adjunct to conventional physical therapies for people living with Parkinson's disease (PD. This systematic review evaluates studies on the outcomes of different dance genres on mobility and quality of life in PD. We searched databases including CINHAL (1982–2015, Medline (1922–2015, Scopus (1996–2015, Web of Science (2002–2015, Embase (2007–2015, PEDro (1999–2015 and the Cochrane Library (1996–2015. The key words were: Parkinson's disease, Parkinson*, Parkinsonism, dance, dance therapy, dance genres, safety, feasibility, and quality of life. Two independent investigators reviewed the texts. Only randomized controlled trials, quasirandomized controlled trials, and case series studies were included. There was emerging evidence that therapeutic dance can be safe and feasible for people with mild to moderately severe PD, with beneficial effects on walking, freezing of gait, and health related quality of life.

  5. Therapeutic approaches for celiac disease

    Plugis, Nicholas M.; Khosla, Chaitan

    2015-01-01

    Celiac disease is a common, lifelong autoimmune disorder for which dietary control is the only accepted form of therapy. A strict gluten-free diet is burdensome to patients and can be limited in efficacy, indicating there is an unmet need for novel therapeutic approaches to supplement or supplant dietary therapy. Many molecular events required for disease pathogenesis have been recently characterized and inspire most current and emerging drug-discovery efforts. Genome-wide association studies (GWAS) confirm the importance of human leukocyte antigen genes in our pathogenic model and identify a number of new risk loci in this complex disease. Here, we review the status of both emerging and potential therapeutic strategies in the context of disease pathophysiology. We conclude with a discussion of how genes identified during GWAS and follow-up studies that enhance susceptibility may offer insight into developing novel therapies. PMID:26060114

    Full Text Available Sinigrin (allyl-glucosinolate or 2-propenyl-glucosinolate is a natural aliphatic glucosinolate present in plants of the Brassicaceae family, such as broccoli and brussels sprouts, and the seeds of Brassica nigra (mustard seeds which contain high amounts of sinigrin. Since ancient times, mustard has been used by mankind for its culinary, as well as medicinal, properties. It has been systematically described and evaluated in the classical Ayurvedic texts. Studies conducted on the pharmacological activities of sinigrin have revealed anti-cancer, antibacterial, antifungal, antioxidant, anti-inflammatory, wound healing properties and biofumigation. This current review will bring concise information about the known therapeutic activities of sinigrin. However, the information on known biological activities is very limited and, hence, further studies still need to be conducted and its molecular mechanisms also need to be explored. This review on the therapeutic benefits of sinigrin can summarize current knowledge about this unique phytocompounds.

  7. Potential Therapeutic Effects of Psilocybin.

    2017-07-01

    Psilocybin and other 5-hydroxytryptamine 2A agonist classic psychedelics have been used for centuries as sacraments within indigenous cultures. In the mid-twentieth century they were a focus within psychiatry as both probes of brain function and experimental therapeutics. By the late 1960s and early 1970s these scientific inquires fell out of favor because classic psychedelics were being used outside of medical research and in association with the emerging counter culture. However, in the twenty-first century, scientific interest in classic psychedelics has returned and grown as a result of several promising studies, validating earlier research. Here, we review therapeutic research on psilocybin, the classic psychedelic that has been the focus of most recent research. For mood and anxiety disorders, three controlled trials have suggested that psilocybin may decrease symptoms of depression and anxiety in the context of cancer-related psychiatric distress for at least 6 months following a single acute administration. A small, open-label study in patients with treatment-resistant depression showed reductions in depression and anxiety symptoms 3 months after two acute doses. For addiction, small, open-label pilot studies have shown promising success rates for both tobacco and alcohol addiction. Safety data from these various trials, which involve careful screening, preparation, monitoring, and follow-up, indicate the absence of severe drug-related adverse reactions. Modest drug-related adverse effects at the time of medication administration are readily managed. US federal funding has yet to support therapeutic psilocybin research, although such support will be important to thoroughly investigate efficacy, safety, and therapeutic mechanisms.

    The study shows that cell kinetics effects correlate with the effects of cytostatic drugs in the tumour model investigated here. It should, however, be noted that even genetically related tumour cell types may react differently to the same cytostatic drug, and that the cell kinetics effects, due to the changes in the cell cycle, cannot be predicted but should be followed with a very fast method, e.g. sequential flan fluorescence cytophotometry, for optimal therapeutic results.

    Cone snails produce a distinctive repertoire of venom peptides that are used both as a defense mechanism and also to facilitate the immobilization and digestion of prey. These peptides target a wide variety of voltage- and ligand-gated ion channels, which make them an invaluable resource for studying the properties of these ion channels in normal and diseased states, as well as being a collection of compounds of potential pharmacological use in their own right. Examples include the United States Food and Drug Administration (FDA) approved pharmaceutical drug, Ziconotide (Prialt; Elan Pharmaceuticals, Inc.) that is the synthetic equivalent of the naturally occurring ?-conotoxin MVIIA, whilst several other conotoxins are currently being used as standard research tools and screened as potential therapeutic drugs in pre-clinical or clinical trials. These developments highlight the importance of driving conotoxin-related research. A PubMed query from 1 January 2007 to 31 August 2011 combined with hand-curation of the retrieved articles allowed for the collation of 98 recently identified conotoxins with therapeutic potential which are selectively discussed in this review. Protein sequence similarity analysis tentatively assigned uncharacterized conotoxins to predicted functional classes. Furthermore, conotoxin therapeutic potential for neurodegenerative disorders (NDD) was also inferred. 2012 by the authors; licensee MDPI.

    2012-01-01

    Full Text Available Peroral cholangioscopy (POC provides direct visualization of the bile duct and facilitates diagnostic or therapeutic intervention. The currently available single-operator POC systems are "Mother-baby" scope system, SpyGlass direct visualization system, and direct POC using a regular ultra-slim upper endoscope. Direct POC using an ultra-slim upper endoscope having a larger 2-mm working channel can provide a valuable and economic solution for evaluating bile-duct lesions. Main diagnostic procedures under direct POC are visual characterization and optically guided target biopsy for the indeterminate bile duct lesion. Image-enhanced endoscopy such as narrow-band imaging has shown promise for more detailed evaluation of mucosal abnormality and can be performed under direct POC. Intracorporeal lithotripsy such as electrohydraulic lithotripsy or laser lithotripsy is a main therapeutic intervention of direct POC for patients with bile duct stones that are resistant to conventional endoscopic stone-removal procedures. Besides, tumor ablation therapy, such as photodynamic therapy and argon plasma coagulation may be also performed using direct POC. Further developments of the endoscope and specialized accessories or devices are expected to facilitate diagnostic and therapeutic role of this cholangioscopic procedure.

    A number of infectious agents have the potential of causing significant clinical symptomology and even death, but dispite this, the number of incidence remain below the level that supports producing a vaccine. Therapeutic antibodies provide a viable treatment option for many of these diseases. We proposed that antibodies derived from West Nile Virus (WNV) immunized geese would be able to treat WNV infection in mammals and potential humans. We demonstrated that WNV specific goose antibodies are indeed successful in treating WNV infection both prophylactically and therapeutically in a golden hamster model. We demonstrated that the goose derived antibodies are non-reactogenic, i.e. do not cause an inflammatory response with multiple exposures in mammals. We also developed both a specific pathogen free facility to house the geese during the antibody production phase and a patent-pending purification process to purify the antibodies to greater than 99% purity. Therefore, the success of these study will allow a cost effective rapidly producible therapeutic toward clinical testing with the necessary infrastructure and processes developed and in place.

    2012-03-01

    The limitation of the therapeutic effort (LTE) consists in not applying extraordinary or disproportionate measures for therapeutic purposes that are proposed for a patient with poor life prognosis and/or poor quality of life. There are two types. The first is to not initiate certain measures or to withdraw them when they are established. A decision of the LTE should be based on some rigorous criteria, so that we make the following proposal. First, it is necessary to know the most relevant details of the case to make a decision: the preferences of the patient, the preferences of the family when pertinent, the prognosis (severity), the quality of life and distribution of the limited resources. After, the decision should be made. In this phase, participatory deliberation should be established to clarify the end of the intervention. Finally, if it is decided to perform an LTE, it should be decided how to do it. Special procedures, disproportionate measures, that are useless and vain should not be initiated for the therapeutic objective designed (withdraw them if they have been established). When it has been decided to treat a condition (interim measures), the treatment should be maintained. This complex phase may need stratification of he measures. Finally, the necessary palliative measures should be established. Copyright © 2011 Elsevier España, S.L. All rights reserved.

  15. Acute Organophosphate Poisonings: Therapeutic Dilemmas and New Potential Therapeutic Agents

    2007-01-01

    It has been six decades since synthesis of organophosphates, but this chapter has not yet come to a closure. Toxic effects of organophosphates are well known and the current therapeutic scheme includes supportive therapy and antidotes. There is a dilemma on whether and when to apply gastric lavage and activated charcoal. According to Position Statement (by EAPCCT) it should be applied only if the patient presents within one hour of ingestion, with potentially lethal ingested dose. Atropine, a competitive antagonist of acetylcholine at m-receptors, which antagonizes bronchosecretion and bronchoconstriction, is the corner stone of acute organophosphate poisoning therapy. There were many attempts to find a more efficient drug, including glycopyrrolate which has been used even in clinical trials, but it still can not replace atropine. The only dilemma about atropine usage which still exists, concerns usage of high atropine dose and scheme of application. The most efficient atropinization is achieved with bolus doses of 1-2mg of atropine i.v push, with repeating the dose on each 5 minutes until signs of atropinization are registered. Diazepam, with its GABA stabilizing effect, reduces central nervous system damage and central respiratory weakness. Oximes reactivate phosphorylated acetylcholinesterase, which still has not gone ageing, reducing acetylcholine concentration and cholinergic crisis. These effects are clearly demonstrated in experimental conditions, but the clinical significance of oximes is still unclear and there are still those who question oxime therapy. For those who approve it, oxime dosage, duration of therapy, the choice of oxime for certain OP is still an open issue. We need new, more efficient antidotes, and those that are in use are only the small part of the therapy which could be used. Experimental studies show favorable therapeutic effect of many agents, but none of them has been introduced in standard treatment of OPI poisoning in the last 30

    Shen, Yuqiao; Senzer, Neil; Nemunaitis, John

    2005-11-01

    The analysis of DNA microarray and proteomic data, and the subsequent integration into functional expression sets, provides a circuit map of the hierarchical cellular networks responsible for sustaining the viability and environmental competitiveness of cancer cells, that is, their robust systematics. These technologies can be used to 'snapshot' the unique patterns of molecular derangements and modified interactions in cancer, and allow for strategic selection of therapeutics that best match the individual profile of the tumour. This review highlights technology that can be used to selectively disrupt critical molecular targets and describes possible vehicles to deliver the synthesised molecular therapeutics to the relevant cellular compartments of the malignant cells. RNA interference (RNAi) involves a group of evolutionarily conserved gene silencing mechanisms in which small sequences of double-stranded RNA or intrinsic antisense RNA trigger mRNA cleavage or translational repression, respectively. Although RNAi molecules can be synthesised to 'silence' virtually any gene, even if upregulated, a mechanism for selective delivery of RNAi effectors to sites of malignant disease remains challenging. The authors will discuss gene-modified conditionally replicating viruses as candidate vehicles for the delivery of RNAi.

    1975-09-01

    Diagnostic and therapeutic radiology were studied as possible contaminants in the evaluations of A-bomb survivors in the ABCC-JNIH Adult Health Study for radiation effects. Hiroshima and Nagasaki subjects received X-ray examinations elsewhere within three months of their ABCC visits at rates of 23 and 12%, respectively. Medical X-ray examinations were more frequent among survivors than comparison subjects. Hiroshima and Nagasaki radiologic practice steadily increased since 1948, and differed markedly by city. From 1946-70 the Hiroshima and Nagasaki X-ray bone marrow doses were 2,300 and 1,000 g-rads, respectively. By 1970, cumulated medical X-ray doses approximated A-bomb doses at distances from the hypocenters of 2,000 m in Hiroshima and 2,800 m in Nagasaki. ABCC X-ray examination doses per subject are routinely updated for comparison with A-bomb doses. Each subject's reported fluoroscopy, photofluorography and radiation therapy exposure elsewhere are for future reference. Dental radiography, though increasing, was not currently an important contributor to survivors' overall exposure. Radiation therapy exposures of 137 subjects were confirmed, and doses estimated for most. Two-thirds the treatments were for malignancies; therapy differed markedly by city; and five cancers possibly arose from earlier radiation therapy. This underscores the importance of considering diagnostic and therapeutic radiology when attributing diseases to the atomic bombs.

    2017-01-01

    Aggressiveness criteria proposed in the scientific literature a decade ago provide a quality judgment and are a reference in the care of patients with advanced cancer, but their use is not generalized in the evaluation of Oncology Services. In this paper we analyze the therapeutic aggressiveness, according to standard criteria, in 1.001 patients with advanced cancer who died in our Institution between 2010 and 2013. The results seem to show that aggressiveness at the end of life is present more frequently than experts recommend. About 25% of patients fulfill at least one criterion of aggressiveness. This result could be explained by a liquid Oncology which does not prioritize the patient as a moral subject in the clinical appointment. Medical care is oriented to necessities and must be articulated in a model focused on dignity and communication. Its implementation through Advanced Care Planning, consideration of patient's values and preferences, and Limitation of therapeutic effort are ways to reduce aggressiveness and improve clinical practice at the end of life. We need to encourage synergic and proactive attitudes, adding the best of cancer research with the best clinical care for the benefit of human being, moral subject and main goal of Medicine.

    Therapeutic drug monitoring (TDM) is commonly recommended to optimize drug dosing regimens of various medications. It has been proposed to guide therapy in pregnant women, in whom physiological changes may lead to altered pharmacokinetics resulting in difficulty in predicting the appropriate drug dosage. Ideally, TDM may play a role in enhancing the effectiveness of treatment while minimizing toxicity of both the mother and fetus. Monitoring of drug levels may also be helpful in assessing adherence to prescribed therapy in selected cases. Limitations exist as therapeutic ranges have only been defined for a limited number of drugs and are based on data obtained in nonpregnant patients. TDM has been suggested for anticonvulsants, antidepressants, and antiretroviral drugs, based on pharmacokinetic studies that have shown reduced drug concentrations. However, there is only relatively limited (and sometimes inconsistent) information regarding the clinical impact of these pharmacokinetic changes during pregnancy and the effect of subsequent dose adjustments. Further studies are required to determine whether implementation of TDM during pregnancy improves outcome and is associated with any benefit beyond that achieved by clinical judgment alone. The cost effectiveness of TDM programs during pregnancy also remains to be examined.

    Roche, Eric

    2014-03-01

    The therapeutic relationship is one of the most central and important factors in the treatment of mental health disorders. A better therapeutic relationship is associated with service engagement, medication adherence, and satisfaction with services. This study aimed to compare the demographic and clinical factors associated with the therapeutic relationship in voluntarily and involuntarily admitted psychiatric service users. We found that individuals who had been admitted involuntarily, who had a diagnosis of a psychotic disorder, and who reported higher levels of perceived pressures on admission were more likely to have a poorer therapeutic relationship with their consultant psychiatrist. Greater levels of insight and treatment satisfaction, together with higher levels of procedural justice experienced on admission, were associated with a better therapeutic relationship. We found that the level of perceived coercion on admission was not related to the therapeutic relationship. Targeted interventions to improve the therapeutic relationship, particularly for involuntarily admitted service users, are discussed.

    Chondrosarcoma is a malignant tumor of bones, characterized by the production of cartilage matrix. Due to lack of effective treatment for advanced disease, the clinical management of chondrosarcomas is exceptionally challenging. Current research focuses on elucidating the molecular events underlying the pathogenesis of this rare bone malignancy, with the goal of developing new molecularly targeted therapies. Signaling pathways suggested to have a role in chondrosarcoma include Hedgehog, Src, PI3k-Akt-mTOR and angiogenesis. Mutations in IDH1/2, present in more than 50% of primary conventional chondrosarcomas, make the development of IDH inhibitors a promising treatment option. The present review discusses the preclinical and early clinical data on novel targeted therapeutic approaches in chondrosarcoma.

    Full Text Available Angiogenesis plays critical roles in human physiology that range from reproduction and fetal growth to wound healing and tissue repair. The sophisticated multistep process is tightly regulated in a spatial and temporal manner by “on-off switch signals” between angiogenic factors, extracellular matrix components, and endothelial cells. Uncontrolled angiogenesis may lead to several angiogenic disorders, including vascular insufficiency (myocardial or critical limb ischemia and vascular overgrowth (hemangiomas, vascularized tumors, and retinopathies. Thus, numerous therapeutic opportunities can be envisaged through the successful understanding and subsequent manipulation of angiogenesis. Here, we review the clinical implications of angiogenesis and discuss pro- and antiangiogenic agents that offer potential therapy for cancer and other angiogenic diseases.

    A novel Fasciclin Related Adhesive Protein (FRAP) from Plasmodium and related parasites is provided as a target for therapeutic intervention in diseases caused by the parasites. FRAP has been shown to play a critical role in adhesion to, or invasion into, host cells by the parasite. Furthermore, FRAP catalyzes the neutralization of heme by the parasite, by promoting its polymerization into hemozoin. This invention provides methods and compositions for therapies based on the administration of protein, DNA or cell-based vaccines and/or antibodies based on FRAP, or antigenic epitopes of FRAP, either alone or in combination with other parasite antigens. Methods for the development of compounds that inhibit the catalytic activity of FRAP, and diagnostic and laboratory methods utilizing FRAP are also provided.

    Various therapeutic interventions have been used in the management of children with cerebral palsy. Traditional physiotherapy and occupational therapy are widely used interventions and have been shown to be of benefit in the treatment of cerebral palsy. Evidence in support of the effectiveness of the neurodevelopmental treatment is equivocal at best. There is evidence to support the use and effectiveness of neuromuscular electrical stimulation in children with cerebral palsy. The effectiveness of many other interventions used in the treatment of cerebral palsy has not been clearly established based on well-controlled trials. These include: sensory integration, body-weight support treadmill training, conductive education, constraint-induced therapy, hyperbaric oxygen therapy, and the Vojta method. This article provides an overview of salient aspects of popular interventions used in the management of children with cerebral palsy.

  13. Guidelines for Rational Cancer Therapeutics

    Directory of Open Access Journals (Sweden)

    Byunghee Yoo

    2017-12-01

    Full Text Available Traditionally, cancer therapy has relied on surgery, radiation therapy, and chemotherapy. In recent years, these interventions have become increasingly replaced or complemented by more targeted approaches that are informed by a deeper understanding of the underlying biology. Still, the implementation of fully rational patient-specific drug design appears to be years away. Here, we present a vision of rational drug design for cancer that is defined by two major components: modularity and image guidance. We suggest that modularity can be achieved by combining a nanocarrier and an oligonucleotide component into the therapeutic. Image guidance can be incorporated into the nanocarrier component by labeling with a specific imaging reporter, such as a radionuclide or contrast agent for magnetic resonance imaging. While limited by the need for additional technological advancement in the areas of cancer biology, nanotechnology, and imaging, this vision for the future of cancer therapy can be used as a guide to future research endeavors.

    2007-11-01

    Aesthetic ideals vary with emerging fashion trends and within different cultures. However, over the past few decades, fuller lips have been considered a desirable trait. Many younger patients are presenting for lip augmentation to achieve the sought-after look commonly seen in many fashion magazines. In addition, as individuals age, they lose lip volume, with a thinning of the red lip, some effacement of the vermillion border, and elongation and flattening of the white portion of the lip. Rejuvenation of the lips plays a key role in restoring a more youthful appearance. As a result, lip augmentation appeals to a wide spectrum of patients who present with various different aesthetic goals and expectations. Numerous therapeutic options exist for aesthetic lip augmentation, ranging from temporary and permanent injectable fillers to implants and other surgical techniques.

    2015-01-01

    Translational nanomedicine occurs only through the successful integration of multiple inputs and iterative modifications. The therapeutic window plays a pivotal role in the trajectory of translational nanomedicine. Often defined in terms of the range of dosage for safe and effective therapeutic effect, a second definition of the therapeutic window refers to the often narrow temporal window in which a therapeutic effect can be obtained. Expanding the second definition to explicitly include the spatial dimension, this article explores aspects of the therapeutic spaces created by nanomedicine that shift the traditional dimensions of symptom, sign and pathology. This article analyzes three aspects of the therapeutic window in nanomedicine - temporal, spatial and manner of construction and their impact on the dimensions of modern medicine.

    Cell transplantation with embryonic stem (ES) cell progeny requires immunological compatibility with host tissue. ‘Therapeutic cloning’ is a strategy to overcome this limitation by generating nuclear transfer (nt)ES cells that are genetically matched to an individual. Here we establish the feasibility of treating individual mice via therapeutic cloning. Derivation of 187 ntES cell lines from 24 parkinsonian mice, dopaminergic differentiation, and transplantation into individually matched host mice showed therapeutic efficacy and lack of immunological response.

  20. Therapeutic targets in liver fibrosis.

    Science.gov (United States)

    Fallowfield, Jonathan A

    2011-05-01

    Detailed analysis of the cellular and molecular mechanisms that mediate liver fibrosis has provided a framework for therapeutic approaches to prevent, slow down, or even reverse fibrosis and cirrhosis. A pivotal event in the development of liver fibrosis is the activation of quiescent hepatic stellate cells (HSCs) to scar-forming myofibroblast-like cells. Consequently, HSCs and the factors that regulate HSC activation, proliferation, and function represent important antifibrotic targets. Drugs currently licensed in the US and Europe for other indications target HSC-related components of the fibrotic cascade. Their deployment in the near future looks likely. Ultimately, treatment strategies for liver fibrosis may vary on an individual basis according to etiology, risk of fibrosis progression, and the prevailing pathogenic milieu, meaning that a multiagent approach could be required. The field continues to develop rapidly and starts to identify exciting potential targets in proof-of-concept preclinical studies. Despite this, no antifibrotics are currently licensed for use in humans. With epidemiological predictions for the future prevalence of viral, obesity-related, and alcohol-related cirrhosis painting an increasingly gloomy picture, and a shortfall in donors for liver transplantation, the clinical urgency for new therapies is high. There is growing interest from stakeholders keen to exploit the market potential for antifibrotics. However, the design of future trials for agents in the developmental pipeline will depend on strategies that enable equal patient stratification, techniques to reliably monitor changes in fibrosis over time, and the definition of clinically meaningful end points.

  1. Therapeutic communities, old and new.

    Science.gov (United States)

    Jones, M

    1979-01-01

    The author attempts to clarify two largely different uses of term, Therapeutic Community (TC). By "old" TC he describes a movement which originated in psychiatry in the United Kingdom at the end of World War II. This was an attempt to establish a democratic system in hospitals where the domination of the doctors was replaced by open communication of content and feeling, information sharing, shared decision making, and problem solving shared as far as possible with all patients and staff. Daily meetings of all patients and staff formed the nucleus of this process. In recent years developments in the areas of systems theory, learning theory, and organization development have contributed to a better understanding of social organization and change. The "new" TCs derive from the more recent developments in the treatment of substance abuse. Central to this movement is Synanon and its many modification which use the clients' peer group to solve their own problems, largely eliminating mental health professionals. Linked with these "new" TCs is the development of Asklepieion units in prisons, which use Synanon "games" along with transactional analysis. An attempt is made to distinguish the methodologies used in TCs, "old" and "new".

  2. Therapeutic drug monitoring of antimicrobials

    2012-01-01

    Optimizing the prescription of antimicrobials is required to improve clinical outcome from infections and to reduce the development of antimicrobial resistance. One such method to improve antimicrobial dosing in individual patients is through application of therapeutic drug monitoring (TDM). The aim of this manuscript is to review the place of TDM in the dosing of antimicrobial agents, specifically the importance of pharmacokinetics (PK) and pharmacodynamics (PD) to define the antimicrobial exposures necessary for maximizing killing or inhibition of bacterial growth. In this context, there are robust data for some antimicrobials, including the ratio of a PK parameter (e.g. peak concentration) to the minimal inhibitory concentration of the bacteria associated with maximal antimicrobial effect. Blood sampling of an individual patient can then further define the relevant PK parameter value in that patient and, if necessary, antimicrobial dosing can be adjusted to enable achievement of the target PK/PD ratio. To date, the clinical outcome benefits of a systematic TDM programme for antimicrobials have only been demonstrated for aminoglycosides, although the decreasing susceptibility of bacteria to available antimicrobials and the increasing costs of pharmaceuticals, as well as emerging data on pharmacokinetic variability, suggest that benefits are likely.

    1989-01-01

    The author's purpose was to evaluate the efficacy of therapeutic embolization in pulmonary hemorrage performed with fibrin foam (Spongostan) suspended in sclerosing agents (hidroxy-poliethoxy-dodecano 3%, or natrium morruate 5%), and electrocoagulation (Bitrol, spa) as an alternative to surgery. Twenty patients were embolized: 17 with fibrin foam and sclerosing agents only, 2 with the addition of electrocoagulation and a Gianturco coil respectively, and 1 with electrocoagulation alone. The follow-up ranges from 3 to 42 months (average 22). A patient affected by aspergilloma died a few days after hemoptysis. The patient treated by electrocoagulation alone suffers from periodical hematic expectoration (spitting). The remaining 18 patients have not shown any pathological findings. In 2 cases the arterial occlusion was confirmed by angiography, while in 1 case partial arterial recanalization was observed. Such a finding was due to the vessel dimensions and to hyperflux values. In similar cases, obstruction must be completed different techniques (e.g. Gianturco coils, electrocoagulation, detachable balloons, etc.). The absence of flux resulting from embolization improves electrocoagulation efficiency, which should be considered as the technique of choice. Even though additional trials are needed, the techniques have proven quite reliable and suitable to replace surgery in low-aggression lesions

    2017-07-01

    Mitochondrial dysfunction has been implicated in a multitude of diseases and pathological conditions- the organelles that are essential for life can also be major players in contributing to cell death and disease. Because mitochondria are so well established in our existence, being present in all cell types except for red blood cells and having the responsibility of providing most of our energy needs for survival, then dysfunctional mitochondria can elicit devastating cellular pathologies that can be widespread across the entire organism. As such, the field of "mitochondrial medicine" is emerging in which disease states are being targeted therapeutically at the level of the mitochondrion, including specific antioxidants, bioenergetic substrate additions, and membrane uncoupling agents. New and compelling research investigating novel techniques for mitochondrial transplantation to replace damaged or dysfunctional mitochondria with exogenous healthy mitochondria has shown promising results, including tissue sparing accompanied by increased energy production and decreased oxidative damage. Various experimental techniques have been attempted and each has been challenged to accomplish successful transplantation. The purpose of this review is to present the history of mitochondrial transplantation, the different techniques used for both in vitro and in vivo delivery, along with caveats and pitfalls that have been discovered along the way. Results from such pioneering studies are promising and could be the next big wave of "mitochondrial medicine" once technical hurdles are overcome.

    Full Text Available Today an obesity became the global epidemic striking both children, and adults and represents one of the most important problems of health care worldwide. Excess accumulation of fatty tissue is resulted by insulin resistance and a compensatory hyperinsulinaemia which are the main predictors of development of a diabetes mellitus type 2. Insulin resistance is also one of key links of a pathogenesis of such diseases as cardiovascular pathology, not-alcoholic fatty liver disease, a polycystic ovary syndrome, gestational diabetes and many others. Depression of sensitivity of tissues to insulin can be physiological reaction of an organism to stress factors and pathological process. The endogenic reasons also take part in development of insulin resistance besides factors of the external environment. The role of genetic predisposition, a subclinical inflammation of fatty tissue, thyroid hormones, adipokines and vitamin D in formation of this pathological process is studied. As insulin resistance takes part in a pathogenesis of various diseases, methods of its diagnostics and correction are of great importance in therapeutic practice. At purpose of treatment it is worth giving preference to the drugs which are positively influencing sensitivity of tissues to insulin.

    Full Text Available Claire E Wainwright1,21Royal Children’s Hospital, Brisbane and Queensland, Queensland, Australia; 2Queensland Children’s Medical Research Institute, The University of Queensland, Brisbane, AustraliaThe idea of children as small adults with health care needs that can be managed by extrapolation from adult studies has now largely been abandoned. We now recognize that adult health and disease are closely linked to childhood factors and the critical and ethical importance of clinical research in pediatrics is increasingly being recognized.  While funding and output from pediatric clinical research continues to lag behind health research in adults, particularly in the area of therapeutics, the last decade has thankfully seen a dramatic increase in the number of pediatric studies and particularly randomized controlled clinical trials (RCTs. Since the 1997 Food and Drug Administration (FDA Modernization Act in the United States (US and the subsequent changes in drug registration regulatory systems in the US and Europe, there has been a huge increase in the number of pediatric studies sponsored by pharmaceutical companies. In the United Kingdom, the Medicine for Children’s Research Network was established in 2005 to address the lack of clinical studies in pediatrics. Over the first five years they reported an exciting increase in the number of high quality clinical studies and on their website they have a current portfolio of over 200 pediatric studies, half of which are RCTs and half are sponsored by pharmaceutical companies. Other countries particularly across Europe are also establishing similar programs. 

  7. Therapeutic strategies in pulmonary hypertension

    Leonello eFuso

    2011-04-01

    Full Text Available Pulmonary hypertension (PH is a life-threatening condition characterized by elevated pulmonary arterial pressure. It is clinically classified into five groups: patients in the first group are considered to have pulmonary arterial hypertension (PAH whereas patients of the other groups have PH that is due to cardiopulmonary or other systemic diseases. The management of patients with PH has advanced rapidly over the last decade and the introduction of specific treatments especially for PAH has lead to an improved outcome. However, despite the progress in the treatment, the functional limitation and the survival of these patients remain unsatisfactory and there is no cure for PAH. Therefore the search for an ideal therapy still goes on. At present, two levels of treatment can be identified: primary and specific therapy. Primary therapy is directed at the underlying cause of the PH. It also includes a supportive therapy consisting in oxygen supplementation, diuretics, and anticoagulation which should be considered in all patients with PH. Specific therapy is directed at the PH itself and includes treatment with vasodilatators such as calcium channel blockers and with vasodilatator and pathogenetic drugs such as prostanoids, endothelin receptor antagonists and phosphodiesterase type-5 inhibitors. These drugs act in several pathogenetic mechanisms of the PH and are specific for PAH although they might be used also in the other groups of PH. Finally, atrial septostomy and lung transplantation are reserved for patients refractory to medical therapy. Different therapeutic approaches can be considered in the management of patients with PH. Therapy can be established on the basis of both the clinical classification and the functional class. It is also possible to adopt a goal-oriented therapy in which the timing of treatment escalation is determined by inadequate response to known prognostic indicators.

    Monroe, Carolyn Magdalen

    2009-06-01

    To better understand how Therapeutic Touch can be used in today's health care arena, this integrative literature review will examine current research that will help answer the question, Does Therapeutic Touch reduce pain? An extensive search was conducted of the online databases MEDLINE, CINAHL, Cochrane Library, EMBASE, PsychLIT, and PubMed to retrieve research articles published from 1997 to 2007. Seven studies that were conducted between 1997 and 2004 were found and only five of the seven were included as pertinent evidence to answer the question. All of the research that was reviewed to answer whether Therapeutic Touch could significantly reduce pain revealed a majority of statistically significant positive results for implementing this intervention. Because there are no identified risks to Therapeutic Touch as a pain relief measure, it is safe to recommend despite the limitations of current research. Therapeutic Touch should be considered among the many possible nursing interventions for the treatment of pain.

    The recent progress in human therapeutics has been made possible thanks to molecular biology and its use in producing proteins having the same sequence and structure as that of human proteins. The use of GMOs allows production of proteins with high added value in therapeutics, which are of satisfactory quality. GMOs may also be directly administered to patients as gene therapy vectors. However, the use of GMOs in therapeutics must take into consideration some risks, particularly those of microbiological contamination, of neo-antigenicity as well as environmental risks with regard to the way of use of the GMO. Nevertheless, those risks are taken in due consideration in the development of these new medicinal products; solutions have been found to allow their use in therapeutics with a very positive benefit/risk ratio. Medicinal products from biotechnology have enabled considerable therapeutic progress without compromising health security.

  13. Oncolytic Viruses: Therapeutics With an Identity Crisis

    Directory of Open Access Journals (Sweden)

    Caroline J. Breitbach

    2016-07-01

    Full Text Available Oncolytic viruses (OV are replicating viral therapeutics for the treatment of cancer and have been in laboratory development for about twenty years. Recently, the FDA approved Imlygic, a herpes virus based therapeutic for the treatment of melanoma and thus OVs have entered a new era where they are a weapon in the armament of the oncologist. OVs are unique therapeutics with multiple mechanisms of therapeutic activity. The exact path for their development and eventual uptake by pharmaceutical companies is somewhat clouded by an uncertain identity. Are they vaccines, tumour lysing therapeutics, inducers of innate immunity, gene therapy vectors, anti-vascular agents or all of the above? Should they be developed as stand-alone loco-regional therapeutics, systemically delivered tumour hunters or immune modulators best tested as combination therapeutics? We summarize data here supporting the idea, depending upon the virus, that OVs can be any or all of these things. Pursuing a “one-size fits all” approach is counter-productive to their clinical development and instead as a field we should build on the strengths of individual virus platforms.

    Therapeutic proteins can face substantial challenges to their activity, requiring protein modification or use of a delivery vehicle. Nanoparticles can significantly enhance delivery of encapsulated cargo, but traditional small molecule carriers have some limitations in their use for protein delivery. Nanoparticles made from protein have been proposed as alternative carriers and have benefits specific to therapeutic protein delivery. This review describes protein nanoparticles made by self-assembly, including protein cages, protein polymers, and charged or amphipathic peptides, and by desolvation. It presents particle fabrication and delivery characterization for a variety of therapeutic and model proteins, as well as comparison of the features of different protein nanoparticles.

    The "therapeutic misconception" describes a process whereby research volunteers misinterpret the intentions of researchers and the nature of clinical research. This misinterpretation leads research volunteers to falsely attribute a therapeutic potential to clinical research, and compromises informed decision making, therefore compromising the ethical integrity of a clinical experiment. We review recent evidence from the neurobiology of social cognition to provide a novel framework for thinking about the therapeutic misconception. We argue that the neurobiology of social cognition should be considered in any ethical analysis of how people make decisions about participating in clinical trials. The neurobiology of social cognition also suggests how the complicated dynamics of the doctor-patient relationship may unavoidably interfere with the process of obtaining informed consent. Following this argument we suggest new ways to prevent or at least mitigate the therapeutic misconception.

    Full Text Available Therapeutic platelet reduction is an effective modality for the reduction of platelet count in patients with treatment of extreme thrombocytosis resulting from a variety of primary and secondary causes of thrombocytosis, which may be associated with thrombotic or hemorrhagic complications of varying degrees. These cases when symptomatic fall into the ASFA Category II indication for therapeutic platelet apheresis procedure. Here, we report a case of postsplenectomy secondary thrombocytosis presenting with extremely high platelet counts and subsequent thrombosis in the shunt and successful treatment after therapeutic platelet reduction. The case is being presented to bring forth the fact that therapeutic platelet reduction is an easy procedure that gives quick and good results and also to bring to the attention of transfusion specialists an associated but as yet unreported procedural finding.

    Recently, there has been a resurgence of interest in nuclear medicine therapeutic procedures. Using unsealed sources for therapy is not a new concept; it has been around since the beginnings of nuclear medicine. Treatment of thyroid disorders with radioiodine is a classic example. The availability of radionuclides with suitable therapeutic properties for specific applications, as well as methods for their selective targeting to diseased tissue have, however, remained the main obstacles for therapy to assume a more widespread role in nuclear medicine. Nonetheless, a number of new techniques that have recently emerged, (e.g., tumor therapy with radiolabeled monoclonal antibodies, treatment of metastatic bone pain, etc.) appear to have provided a substantial impetus to research on production of new therapeutic radionuclides. Although there are a number of new therapeutic approaches requiring specific radionuclides, only selected broad areas will be used as examples in this article

    Zuckerman, Jonathan E; Davis, Mark E

    2013-11-01

    Nanoparticles are an enabling technology for the creation of tissue-/cell-specific therapeutics that have been investigated extensively as targeted therapeutics for cancer. The kidney, specifically the glomerulus, is another accessible site for nanoparticle delivery that has been relatively overlooked as a target organ. Given the medical need for the development of more potent, kidney-targeted therapies, the use of nanoparticle-based therapeutics may be one such solution to this problem. Here, we review the literature on nanoparticle targeting of the glomerulus. Specifically, we provide a broad overview of nanoparticle-based therapeutics and how the unique structural characteristics of the glomerulus allow for selective, nanoparticle targeting of this area of the kidney. We then summarize literature examples of nanoparticle delivery to the glomerulus and elaborate on the appropriate nanoparticle design criteria for glomerular targeting. Finally, we discuss the behavior of nanoparticles in animal models of diseased glomeruli and review examples of nanoparticle therapeutic approaches that have shown promise in animal models of glomerulonephritic disease.

  7. Therapeutic Vaccination for HPV Induced Cervical Cancers

    Directory of Open Access Journals (Sweden)

    Joeli A. Brinkman

    2007-01-01

    Full Text Available Cervical Cancer is the second leading cause of cancer–related deaths in women worldwide and is associated with Human Papillomavirus (HPV infection, creating a unique opportunity to treat cervical cancer through anti-viral vaccination. Although a prophylactic vaccine may be available within a year, millions of women, already infected, will continue to suffer from HPV-related disease, emphasizing the need to develop therapeutic vaccination strategies. A majority of clinical trials examining therapeutic vaccination have shown limited efficacy due to examining patients with more advanced-stage cancer who tend to have decreased immune function. Current trends in clinical trials with therapeutic agents examine patients with pre-invasive lesions in order to prevent invasive cervical cancer. However, longer follow-up is necessary to correlate immune responses to lesion regression. Meanwhile, preclinical studies in this field include further exploration of peptide or protein vaccination, and the delivery of HPV antigens in DNA-based vaccines or in viral vectors. As long as pre-clinical studies continue to advance, the prospect of therapeutic vaccination to treat existing lesions seem good in the near future. Positive consequences of therapeutic vaccination would include less disfiguring treatment options and fewer instances of recurrent or progressive lesions leading to a reduction in cervical cancer incidence.

    Long-term care facilities are increasingly incorporating some sort of kitchen, often referred to as a therapeutic kitchen, for resident, staff, and family use through remodeling efforts or new construction. A study, consisting of five site visits and a questionnaire mailed to 631 facilities providing dementia care, was conducted to identify physical features that are typically included in therapeutic kitchen design and to explore how these features support daily use in relation to activities programming and food service systems. Findings indicate that universal design features should be incorporated to a greater extent and certain features are more common, reinforce homelike imagery, or enhance safety. Results also suggest that a higher number of residents participate in more recreational activities, such as baking, than they do in household chores, such as meal set-up, and therapeutic kitchens are not always linked to food service systems.

    2014-01-01

    During the last decade, various functional nanostructured materials with interesting optical, magnetic, mechanical and chemical properties have been extensively applied to biomedical areas including imaging, diagnosis and therapy. In therapeutics, most research has focused on the application of nanoparticles as potential delivery vehicles for drugs and genes, because nanoparticles in the size range of 2-100 nm can interact with biological systems at the molecular level, and allow targeted delivery and passage through biological barriers. Recent investigations have even revealed that several kinds of nanomaterials are intrinsically therapeutic. Not only can they passively interact with cells, but they can also actively mediate molecular processes to regulate cell functions. This can be seen in the treatment of cancer via anti-angiogenic mechanisms as well as the treatment of neurodegenerative diseases by effectively controlling oxidative stress. This review will present recent applications of inorganic nanoparticles as therapeutic agents in the treatment of disease.

  11. Botanical polysaccharides: macrophage immunomodulation and therapeutic potential.

    Science.gov (United States)

    Schepetkin, Igor A; Quinn, Mark T

    2006-03-01

    Botanical polysaccharides exhibit a number of beneficial therapeutic properties, and it is thought that the mechanisms involved in these effects are due to the modulation of innate immunity and, more specifically, macrophage function. In this review, we summarize our current state of understanding of the macrophage modulatory effects of botanical polysaccharides isolated from a wide array of different species of flora, including higher plants, mushrooms, lichens and algae. Overall, the primary effect of botanical polysaccharides is to enhance and/or activate macrophage immune responses, leading to immunomodulation, anti-tumor activity, wound-healing and other therapeutic effects. Furthermore, botanical and microbial polysaccharides bind to common surface receptors and induce similar immunomodulatory responses in macrophages, suggesting that evolutionarily conserved polysaccharide structural features are shared between these organisms. Thus, the evaluation of botanical polysaccharides provides a unique opportunity for the discovery of novel therapeutic agents and adjuvants that exhibit beneficial immunomodulatory properties.

    Rapport is established at the first meeting between the patient and nurse, and is developed throughout the therapeutic relationship. However, challenges can arise during this process. Initially, nurses can establish trust with the patient through the questions they ask, however, as care progresses, the nurse will be required to demonstrate a commitment to maintaining the patient's psychological well-being. When the therapeutic relationship ends, the nurse should assist the patient to assess progress and plan the next stage of recovery. This article provides three reflective exercises using case study examples to demonstrate how rapport is developed and sustained. Evidence is provided to identify why challenges arise in the therapeutic relationship and how the nurse can ensure they provide care that the patient regards as genuine.

    Lin, Ken; Doolan, Kimberley; Hung, Chien-Fu; Wu, T-C

    2010-01-01

    Cervical cancer is the second most common cause of female cancer death worldwide. Persistent infection with `high risk' HPV genotypes is the major etiological factor in cervical cancer and thus effective vaccination against HPV provides an opportunity to reduce the morbidity and mortality associated with HPV. The FDA has approved two preventive vaccines to limit the spread of HPV. However, these are unlikely to impact upon HPV prevalence and cervical cancer rates for many years. Furthermore, preventive vaccines do not exert therapeutic effects on pre-existing HPV infections and HPV-associated lesions. In order to further impact upon the burden of HPV infections worldwide, therapeutic vaccines are being developed. These vaccines aim to generate a cell-mediated immune response to infected cells. This review discusses current preventive and therapeutic HPV vaccines and their future directions. PMID:20123582

    Oligonucleotide-based therapeutics have made rapid progress in the clinic for treatment of a variety of disease indications. Unmodified oligonucleotides are polyanionic macromolecules with poor drug-like properties. Over the past two decades, medicinal chemists have identified a number of chemical modification and conjugation strategies which can improve the nuclease stability, RNA-binding affinity, and pharmacokinetic properties of oligonucleotides for therapeutic applications. In this perspective, we present a summary of the most commonly used nucleobase, sugar and backbone modification, and conjugation strategies used in oligonucleotide medicinal chemistry.

    Graves' disease is the most common cause of hyperthyroidism. Clinical features include thyroid enlargement, eye signs, tachycardia, heat intolerance, emotional lability, weight loss, and hyperkinesis. Three modes of therapy are available. The preferences of the patient and physician are usually prime considerations in devising the therapeutic plan. Radioactive iodine is the most frequently used and safest method of treatment for adults. Antithyroid drugs are preferred for children and pregnant women. Surgery is usually reserved for patients in whom the other forms of treatment are not acceptable. Considerable patient education during the decision-making process enhances the success of the therapeutic plan

    2018-03-01

    Full Text Available Neurosteroids are a group of important endogenous molecules affecting many neural functions in the brain. Increasing evidence suggests a possible role of these neurosteroids in the pathology and symptomatology of schizophrenia (SZ and other mental disorders. The aim of this review is to summarize the current knowledge about the neural functions of neurosteroids in the brain, and to evaluate the role of the key neurosteroids as candidate modulators in the etiology and therapeutics of SZ. The present paper provides a brief introduction of neurosteroid metabolism and distribution, followed by a discussion of the mechanisms underlying neurosteroid actions in the brain. The content regarding the modulation of the GABAA receptor is elaborated, given the considerable knowledge of its interactions with other neurotransmitter and neuroprotective systems, as well as its ameliorating effects on stress that may play a role in the SZ pathophysiology. In addition, several preclinical and clinical studies suggested a therapeutic benefit of neurosteroids in SZ patients, even though the presence of altered neurosteroid pathways in the circulating blood and/or brain remains debatable. Following treatment of antipsychotic drugs in SZ, therapeutic benefits have also been linked to the regulation of neurosteroid signaling. Specifically, the neurosteroids such as pregnenolone and dehydroepiandrosterone affect a broad spectrum of behavioral functions through their unique molecular characteristics and may represent innovative therapeutic targets for SZ. Future investigations in larger cohorts with long-term follow-ups will be required to ascertain the neuropsychopharmacological role of this yet unexploited class of neurosteroid agents.

    The present study had 2 aims: (a) to implement West and Kenny's (2011) Truth-and-Bias model to simultaneously assess the temporal congruence and directional discrepancy between clients' and therapists' ratings of the bond facet of the therapeutic alliance, as they cofluctuate from session to session; and (b) to examine whether symptom severity and a personality disorder (PD) diagnosis moderate congruence and/or discrepancy. Participants included 213 clients treated by 49 therapists. At pretreatment, clients were assessed for a PD diagnosis and completed symptom measures. Symptom severity was also assessed at the beginning of each session, using client self-reports. Both clients and therapists rated the therapeutic bond at the end of each session. Therapists and clients exhibited substantial temporal congruence in their session-by-session bond ratings, but therapists' ratings tended to be lower than their clients' across sessions. Additionally, therapeutic dyads whose session-by-session ratings were more congruent also tended to have a larger directional discrepancy (clients' ratings being higher). Pretreatment symptom severity and PD diagnosis did not moderate either temporal congruence or discrepancy at the dyad level; however, during sessions when clients were more symptomatic, therapist and client ratings were both farther apart and tracked each other less closely. Our findings are consistent with a "better safe than sorry" pattern, which suggests that therapists are motivated to take a vigilant approach that may lead both to underestimation and to attunement to fluctuations in the therapeutic bond.

    Advances in imaging and spectroscopic technologies have enabled the optimization of many therapeutic modalities in cancer and noncancer pathologies either by earlier disease detection or by allowing therapy monitoring. Amongst the therapeutic options benefiting from developments in imaging technologies, photodynamic therapy (PDT) is exceptional. PDT is a photochemistry-based therapeutic approach where a light-sensitive molecule (photosensitizer) is activated with light of appropriate energy (wavelength) to produce reactive molecular species such as free radicals and singlet oxygen. These molecular entities then react with biological targets such as DNA, membranes and other cellular components to impair their function and lead to eventual cell and tissue death. Development of PDT-based imaging also provides a platform for rapid screening of new therapeutics in novel in vitro models prior to expensive and labor-intensive animal studies. In this study we demonstrate how an imaging platform can be used for strategizing a novel combination treatment strategy for multifocal ovarian cancer. Using an in vitro 3D model for micrometastatic ovarian cancer in conjunction with quantitative imaging we examine dose and scheduling strategies for PDT in combination with carboplatin, a chemotherapeutic agent presently in clinical use for management of this deadly form of cancer.

    2017-09-01

    Biologics or therapeutic proteins are becoming increasingly important as treatments for disease. The most common class of biologics are monoclonal antibodies (mAbs). Recently, there has been an increase in the use of physiologically based pharmacokinetic (PBPK) modeling in the pharmaceutical industry in drug development. We review PBPK models for therapeutic proteins with an emphasis on mAbs. Due to their size and similarity to endogenous antibodies, there are distinct differences between PBPK models for small molecules and mAbs. The high-level organization of a typical mAb PBPK model consists of a whole-body PBPK model with organ compartments interconnected by both blood and lymph flows. The whole-body PBPK model is coupled with tissue-level submodels used to describe key mechanisms governing mAb disposition including tissue efflux via the lymphatic system, elimination by catabolism, protection from catabolism binding to the neonatal Fc (FcRn) receptor, and nonlinear binding to specific pharmacological targets of interest. The use of PBPK modeling in the development of therapeutic proteins is still in its infancy. Further application of PBPK modeling for therapeutic proteins will help to define its developing role in drug discovery and development. Copyright © 2017 American Pharmacists Association®.

    2011-11-01

    Recombinant antibodies specific for human targets are often used as therapeutics and represent a major class of drug products. Their therapeutic efficacy depends on the formation of antibody complexes resulting in the elimination of a target molecule or the modulation of specific signalling pathways. The physiological effects of antibody therapeutics are known to depend on the structural characteristics of the antibody molecule, specifically on the glycosylation which is the result of posttranslational modifications. Hence, production of therapeutic antibodies with a defined and consistent glycoform profile is needed which still remains a considerable challenge to the biopharmaceutical industry. To provide an insight into the industries capability to control their manufacturing process and to provide antibodies of highest quality, we conducted a market surveillance study and compared major oligosaccharide profiles of a number of monoclonal antibody pharmaceuticals sampled on the Swiss market. Product lot-to-lot variability was found to be generally low, suggesting that a majority of manufacturers have implemented high quality standards in their production processes. However, proportions of G0, G1 and G2 core-fucosylated chains derived from different products varied considerably and showed a bias towards the immature agalactosidated G0 form. Interestingly, differences in glycosylation caused by the production cell type seem to be of less importance compared with process related parameters such as cell growth.

    Singh, Satish K; Cousens, Leslie P; Alvarez, David; Mahajan, Pramod B

    2012-09-01

    Protein therapeutics occupy a very significant position in the biopharmaceutical market. In addition to the preclinical, clinical and post marketing challenges common to other drugs, unwanted immunogenicity is known to affect efficacy and/or safety of most biotherapeutics. A standard set of immunogenicity risk factors are routinely used to inform monitoring strategies in clinical studies. A number of in-silico, in vivo and in vitro approaches have also been employed to predict immunogenicity of biotherapeutics, but with limited success. Emerging data also indicates the role of immune tolerance mechanisms and impact of several product-related factors on modulating host immune responses. Thus, a comprehensive discussion of the impact of innate and adaptive mechanisms and molecules involved in induction of host immune responses on immunogenicity of protein therapeutics is needed. A detailed understanding of these issues is essential in order to fully exploit the therapeutic potential of this class of drugs. This Roundtable Session was designed to provide a common platform for discussing basic immunobiological and pharmacological issues related to the role of biotherapeutic-associated risk factors, as well as host immune system in immunogenicity against protein therapeutics. The session included overview presentations from three speakers, followed by a panel discussion with audience participation. Copyright © 2012. Published by Elsevier Ltd.. All rights reserved.

    2016-04-01

    Full Text Available This article discusses the issue of unique therapeutic projects within the mental health services built in the Brazilian psychiatric reform process. Starting from the concepts that have gained strength in both the psychiatric reform as in the collective health, this study proposes that current notions of the therapeutic project still are influenced by biological, psychological or social paradigms that simplify the complexity of the experience suffered by the subjects. Despite therapeutic projects are an essential achievement for the qualification of mental health care, it is still necessary to produce an epistemological rupture in the relationship with mental suffering so that they can achieve the greatest potential for transformation. Therefore, the article suggests that the practice of therapeutic projects should hold discussions with the reality of users life of and their relationships in the territories of existence, to transform the relations of power and knowledge that reproduce the subjects annulment. Thus, it is possible to dialogue with the complexity of the mental suffering experience, producing changes in the scenes that produce it.

    The concept of utilizing polymers in drug delivery has been extensively explored for improving the therapeutic index of small molecule drugs. In general, polymers can be used as polymer-drug conjugates or polymeric micelles. Each unique application mandates its own chemistry and controlled release of active drugs. Each polymer exhibits its own intrinsic issues providing the advantage of flexibility. However, none have as yet been approved by the U.S. Food and Drug Administration. General aspects of polymer and nano-particle therapeutics have been reviewed. Here we focus this review on specific clinically relevant anticancer polymer paclitaxel therapeutics. We emphasize their chemistry and formulation, in vitro activity on some human cancer cell lines, plasma pharmacokinetics and tumor accumulation, in vivo efficacy, and clinical outcomes. Furthermore, we include a short review of our recent developments of a novel poly(l-γ-glutamylglutamine)-paclitaxel nano-conjugate (PGG-PTX). PGG-PTX has its own unique property of forming nano-particles. It has also been shown to possess a favorable profile of pharmacokinetics and to exhibit efficacious potency. This review might shed light on designing new and better polymer paclitaxel therapeutics for potential anticancer applications in the clinic.

    2018-06-01

    Recent research on psychedelics and hypnosis demonstrates the value of both methods in the treatment of a range of psychopathologies with overlapping applications and neurophenomenological features. The potential of harnessing the power of suggestion to influence the phenomenological response to psychedelics toward more therapeutic action has remained unexplored in recent research and thereby warrants empirical attention. Here we aim to elucidate the phenomenological and neurophysiological similarities and dissimilarities between psychedelic states and hypnosis in order to revisit how contemporary knowledge may inform their conjunct usage in psychotherapy. We review recent advances in phenomenological and neurophysiological research on psychedelics and hypnosis, and we summarize early investigations on the coupling of psychedelics and hypnosis in scientific and therapeutic contexts. Results/outcomes: We highlight commonalities and differences between psychedelics and hypnosis that point to the potential efficacy of combining the two in psychotherapy. We propose multiple research paths for coupling these two phenomena at different stages in the preparation, acute phase and follow-up of psychedelic-assisted psychotherapy in order to prepare, guide and integrate the psychedelic experience with the aim of enhancing therapeutic outcomes. Harnessing the power of suggestion to modulate response to psychedelics could enhance their therapeutic efficacy by helping to increase the likelihood of positive responses, including mystical-type experiences.

  8. Therapeutic enhancement: nursing intervention category for patients diagnosed with Readiness for Therapeutic Regimen Management.

    2008-04-01

    To present a new nursing intervention category called therapeutic enhancement. Fewer than half of North Americans follow their physician's recommendations for diet and exercise, even when such are crucial to their health or recovery. It is imperative that nurses consider new ways to promote healthy behaviours. Therapeutic enhancement is intended to provide such a fresh approach. Traditional intervention techniques focusing on education, contracts, social support and more frequent interaction with physicians appear not to be effective when used alone. Successful strategies have been multidisciplinary; and have included interventions by professional nurses who assist patients to understand their disease and the disease process and that helps them to develop disease-management and self-management skills. Therapeutic enhancement incorporates The Stages of Change Theory, Commitment to Health Theory, Motivational Interviewing techniques and instrumentation specifically designed for process evaluation of health-promoting interventions. This is a critical review of approaches that, heretofore, have not been synthesised in a single published article. Based on the commonly used Stages of Change model, therapeutic enhancement is useful for patients who are at the action stage of change. Using therapeutic enhancement as well as therapeutic strategies identified in Stages of Change Theory, such as contingency management, helping relationships, counterconditioning, stimulus control and Motivational Interviewing techniques, nursing professionals can significantly increase the chances of patients moving from action to the maintenance stage of change for a specific health behaviour. Using the nursing intervention category, therapeutic enhancement can increase caregivers' success in helping patients maintain healthy behaviours.

    Acute pulmonary embolism (PE) is a potentially fatal manifestation of venous thromboembolism. Prompt anticoagulant treatment is crucial for PE patients, which can decrease morbidity and mortality. Risk assessment is the cornerstone of the therapeutic management of PE. It guides physicians to the most appropriate treatment and selects patients for early discharge or home treatment. Areas covered: Here, we review the current treatments of acute PE according to contemporary risk stratification strategies, highlighting each step of PE therapeutic management. Expert commentary: Currently, direct oral anticoagulants (DOACs) represent the first-line therapy of patients presenting with non-high risk PE with a better risk-benefit ratios than vitamin K antagonists (VKAs) due to lower risk of major bleeding. Only high-risk patients with PE who present in shock should be treated with systematic thrombolysis, while surgical thrombectomy or catheter direct thrombolysis (CDT) should only be considered when thrombolysis is contraindicated because of too high bleeding risk.

  10. Therapeutic Oligonucleotides Targeting Liver Disease: TTR Amyloidosis

    Directory of Open Access Journals (Sweden)

    Christoph Niemietz

    2015-09-01

    Full Text Available The liver has become an increasingly interesting target for oligonucleotide therapy. Mutations of the gene encoding transthyretin (TTR, expressed in vast amounts by the liver, result in a complex degenerative disease, termed familial amyloid polyneuropathy (FAP. Misfolded variants of TTR are linked to the establishment of extracellular protein deposition in various tissues, including the heart and the peripheral nervous system. Recent progress in the chemistry and formulation of antisense (ASO and small interfering RNA (siRNA designed for a knockdown of TTR mRNA in the liver has allowed to address the issue of gene-specific molecular therapy in a clinical setting of FAP. The two therapeutic oligonucleotides bind to RNA in a sequence specific manner but exploit different mechanisms. Here we describe major developments that have led to the advent of therapeutic oligonucleotides for treatment of TTR-related disease.

    2003-01-01

    "Dry eye syndrome" is a common disorder of the tear film that results from inadequate tear production, excessive tear evaporation or abnormality in mucin or lipid components of the tear film. A number of 53 patients suffering from dry eye syndrome were followed up for a period of 18 months. The study group was heterogeneous, including a lot of conditions accompanied by dry eye syndrome: Syogren's syndrome, lupus erythematous, ocular rosacea, patients with systemic treatments with antidepressants, betablockers, diuretics, oral contraceptives, glaucomatous patients with topical beta-blockers, postmenopausal women, aging people, computer users and long-term contact lens wearers. The therapeutical options were dictated by the severity of the syndrome: substitution therapy, treatment of the underlying eyelid diseases, modifying of the environmental conditions and treatment of the complications in the most severe cases. The new pathological approach is innovative and it may provide a real therapeutical measure for this condition: topical A Cyclosporine and androgen drops.

    Arthritis represents a family of complex joint pathologies responsible for the majority of musculoskeletal conditions. Nearly all diseases within this family, including osteoarthritis, rheumatoid arthritis, and juvenile idiopathic arthritis, are chronic conditions with few or no disease-modifying therapeutics available. Advances in genome engineering technology, most recently with CRISPR-Cas9, have revolutionized our ability to interrogate and validate genetic and epigenetic elements associated with chronic diseases such as arthritis. These technologies, together with cell reprogramming methods, including the use of induced pluripotent stem cells, provide a platform for human disease modeling. We summarize new evidence from genome-wide association studies and genomics that substantiates a genetic basis for arthritis pathogenesis. We also review the potential contributions of genome engineering in the development of new arthritis therapeutics. Copyright © 2017 Elsevier Ltd. All rights reserved.

    To explore the reasonable therapeutic strategy for different types of epicanthus. Patients with epicanthus were classificated according to the shape, extent and inner canthal distance and treated with different methods appropriately. Modified asymmetric Z plasty with two curve method was used in lower eyelid type epicanthus, inner canthus type epicanthus and severe upper eyelid type epicanthus. Moderate upper epicanthus underwent '-' shape method. Mild Upper epicanthus in two conditions which underwent nasal augumentation and double eyelid formation with normal inner canthal distance need no correction surgery. The other mild epicanthus underwent '-' shape method. A total of 66 cases underwent the classification and the appropriate treatment. All wounds healed well. During 3 to 12 months follow-up period, all epicanthus were corrected completely with natural contour and unconspicuous scars. All patients were satisfied with the results. Classification of epicanthus hosed on the shape, extent and inner canthal distance and correction with appropriate methods is a reasonable therapeutic strategy.

    Cancer markers may be developed to detect diseases characterized by increased expression of apoptosis-suppressing genes, such as aggressive cancers. Genes in the human chromosomal regions, 8q24, 11q13, 20q11-q13, were found to be amplified indicating in vivo drug resistance in diseases such as ovarian cancer. Diagnosis and assessment of amplification levels certain genes shown to be amplified, including PVT1, can be useful in prediction of poor outcome of patient's response and drug resistance in ovarian cancer patients with low survival rates. Certain genes were found to be high priority therapeutic targets by the identification of recurrent aberrations involving genome sequence, copy number and/or gene expression are associated with reduced survival duration in certain diseases and cancers, specifically ovarian cancer. Therapeutics to inhibit amplification and inhibitors of one of these genes, PVT1, target drug resistance in ovarian cancer patients with low survival rates is described.

    1997-01-01

    Graves' disease presents itself clinically mainly as hyperthyroidism and infiltrative ophthalmopathy and to a minimal extent also as dermopathy and acropachy. Autoimmune processes are the basic pathogenesis. Stimulating antibodies against the TSH receptor cause hyperthyroidism. Autoantibodies and autoreactive T lymphocytes against primarily thyroidal antigens cross-react with similar antigens of the eye muscles and orbital connective tissue, thus spreading the disease from the thyroid to the eyes. The therapeutic goal comprises not only the treatment of hyperthyroidism, but also the induction of a steady immuntolerance in order to minimize the irreversible damage to the eye. The therapeutic armamentarium is formed by antithyroid drugs, glucocorticoids, retrobulbar radition and thyroid ablation, either by nearly total thyroidectomy or by radioiodine. The different indications for both ablative procedures are discussed. (orig.) [de

    2013-05-01

    During pregnancy, a progressive increase in serum triglyceride (TG) and cholesterol levels is observed whereas TG levels mostly remain hypertriglyceridemia, pregnancy may cause extremely elevated TG levels leading to potentially life-threatening pancreatitis attacks and chylomicronemia syndrome. The only safe medical treatment option during pregnancy is ω-3 fatty acids, which have moderate TG lowering effects. Therapeutic apheresis could be used as primary treatment approach during pregnancy. We reported the effect of double filtration apheresis in one pregnant women with severe hypertriglyceridemia, therapeutic plasmapheresis and double filtration methods in the other severe hypertriglyceridemic pregnant woman; a 32-year-old pregnant woman (patient 1) with a history of hypertriglyceridemia-induced acute pancreatitis during pregnancy and a 30-year-old pregnant woman with extremely high TG levels (12,000 mg/dl) leading to chylomicronemia syndrome (patient 2). Medical nutrition therapy and ω-3 fatty acids were also provided. Double filtration apheresis (patient 1) and plasmapheresis + double filtration apheresis (patient 2) were used. When we calculated the TG levels before and after therapeutic apheresis, maximum decrease achieved with double filtration apheresis was 46.3 % for patient 1 and 37.3 % for patient 2. However, with plasmapheresis TG level declined by 72 % in patient 2. Plasmapheresis seemed to be more efficient to decrease TG levels. Iron deficiency anemia was the main complication apart from technical difficulties by lipemic obstruction of tubing system. Healthy babies were born. Delivery led to decreases in TG levels. It is concluded that during pregnancy therapeutic apheresis is an effective method to decrease extremely high TG levels and risks of its potentially life-threatening complications.

  8. A therapeutic gain model for brachytherapy

    International Nuclear Information System (INIS)

    Wigg, D.R.

    2003-01-01

    When treating with continuous irradiation the potential therapeutic gain or loss depends on several treatment, normal tissue and tumour variables. There are similarities between equations defining tissue effects with fractionated treatment and brachytherapy. The former is sensitive to dose per fraction (and incomplete repair for short intervals between treatments) and the later is sensitive to dose rate and continuous repair factors. Because of these similarities, for typical tumours and normal tissues, dose per fraction and dose rates generally work in similar directions. As the dose per fraction or dose rate increases the therapeutic gain falls. With continuous irradiation the dose rates effects are determined by Beta cell kill and hence the absolute value of Beta . Minimal sensitivity occurs at very low and very high dose rates. The magnitude of cell kill also depends on the Continuous Repair Factor (g) which is a function of the treatment time and the Repair Half Time (in hours) of the tissues (Repair Half Time T 1/2Ln(2)/h, when h the Repair Constant). An interactive optimising model has been written to predict the therapeutic gain or loss as the parameter values are varied. This model includes the tumour and normal tissue parameters alpha and beta Gy (or individual values), their Repair Half Times, dose rates and overall treatment time. The model is based on the Linear-Quadratic equation and the Total Effect (TE) method of Thames and Hendry although the Extrapolated Response Dose (ERD) method of Barendsen produces the same results. The model is written so that the gain or loss may be seen when treatment is always to normal tissue tolerance doses. The magnitude of the therapeutic loss as the dose rate increases and its sensitivity to changes in normal tissue and tumour parameter values is clearly demonstrated

    Development and progress of cancer is a very complex disease process to comprehend because of the multiple changes in cellular physiology, pathology, and pathophysiology resulting from the numerous genetic changes from which cancer originates. As a result, most common treatments are not directed at the molecular level but rather at the tissue level. While personalized care is becoming an increasingly aim, the most common cancer treatments are restricted to chemotherapy, radiation, and surgery, each of which has a high likelihood of resulting in rather severe adverse side effects. For example, currently used radiation therapy does not discriminate between normal and cancerous cells and greatly relies on the external targeting of the radiation beams to specific cells and organs. Because of this, there is an immediate need for the development of new and innovative technologies that help to differentiate tumor cells and micrometastases from normal cells and facilitate the complete destruction of those cells. Recent advancements in nanoscience and nanotechnology have paved a way for the development of nanoparticles (NPs) as multifunctional carriers to deliver therapeutic radioisotopes for tumor targeted radiation therapy, to monitor their delivery, and improve the therapeutic index of radiation and tumor response to the treatment. The application of NPs in radiation therapy has aimed to improve outcomes in radiation therapy by increasing therapeutic effect in tumors and reducing toxicity on normal tissues. Because NPs possess unique properties, such as preferential accumulation in tumors and minimal uptake in normal tissues, it makes them ideal for the delivery of radiotherapy. This review provides an overview of the recent development of NPs for carrying and delivering therapeutic radioisotopes for systemic radiation treatment for a variety of cancers in radiation oncology.

  11. Use of informed consent with therapeutic paradox.

    Debate persists in the literature and among clinicians about the ethical appropriateness of paradoxical interventions. It has been suggested that informed consent with therapeutic paradox would alleviate ethical concerns of deception, manipulation, harm to the client, and withholding of information from the client in therapy. The purpose of this study was to explore health care consumer reactions to the benefits and risks of therapeutic paradox as stated in a consent for treatment form. The study explored the responses of 32 medical patients to a hypothetical consent for treatment form for therapeutic paradox. Data were collected in a brief semistructured interview after subjects read the hypothetical consent form. Utilizing a case study, the investigator then offered an example of a successful paradoxical intervention and additional subject comments were solicited. Content analysis of the responses was made. Health care consumers had mixed responses to the consent form. While the consent form served as an obstacle for some consumers, many were willing to sign the consent form and accept treatment even though they had internal reservations and questions. Appropriateness of the consent form format is discussed.

  12. Pain and endometriosis: Etiology, impact, and therapeutics

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available The association of pain and endometriosis was recognized with the first definitive published reports of this disorder. Unfortunately, the precise etiologies and pathways leading to nociception and pain symptoms in endometriosis remain poorly understood, and as a result, effective therapeutic interventions are lacking with consequent profound effects on affected women’s quality of life. In this opinion paper we summarize selected proceedings presented at the 28th Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE in Istanbul, Turkey, and review the clinical and translational evidence of chronic pain, neurogenesis, and the pernicious impact of dyspareunia on women with symptomatic endometriosis. The effectiveness of medical treatments is critically assessed and the findings indicate that good therapeutic options are available with extant medications effective in some sub-groups of women with endometriosis, many of which are affordable globally. Nevertheless, new management strategies and drugs need to be developed to increase the options of all afflicted women to minimize and ideally eradicate painful symptoms of endometriosis. However, only by elucidating distinctions among sub-groups with specific symptoms, suggesting different mechanisms, are we likely to derive truly successful therapeutic strategies.

  13. Toxicological perspectives of inhaled therapeutics and nanoparticles.

    The human respiratory system is an important route for the entry of inhaled therapeutics into the body to treat diseases. Inhaled materials may consist of gases, vapours, aerosols and particulates. In all cases, assessing the toxicological effect of inhaled therapeutics has many challenges. This article provides an overview of in vivo and in vitro models for testing the toxicity of inhaled therapeutics and nanoparticles implemented in drug delivery. Traditionally, inhalation toxicity has been performed on test animals to identify the median lethal concentration of airborne materials. Later maximum tolerable concentration denoted by LC0 has been introduced as a more ethically acceptable end point. More recently, in vitro methods have been developed, allowing the direct exposure of airborne material to cultured human target cells on permeable porous membranes at the air-liquid interface. Modifications of current inhalation therapies, new pulmonary medications for respiratory diseases and implementation of the respiratory tract for systemic drug delivery are providing new challenges when conducting well-designed inhalation toxicology studies. In particular, the area of nanoparticles and nanocarriers is of critical toxicological concern. There is a need to develop toxicological test models, which characterise the toxic response and cellular interaction between inhaled particles and the respiratory system.

  14. Therapeutic strategies to improve control of hypertension.

    Armario, Pedro; Waeber, Bernard

    2013-03-01

    Blood pressure is poorly controlled in most European countries and the control rate is even lower in high-risk patients such as patients with chronic kidney disease, diabetic patients or previous coronary heart disease. Several factors have been associated with poor control, some of which involve the characteristic of the patients themselves, such as socioeconomic factors, or unsuitable life-styles, other factors related to hypertension or to associated comorbidity, but there are also factors directly associated with antihypertensive therapy, mainly involving adherence problems, therapeutic inertia and therapeutic strategies unsuited to difficult-to-control hypertensive patients. It is common knowledge that only 30% of hypertensive patients can be controlled using monotherapy; all the rest require a combination of two or more antihypertensive drugs, and this can be a barrier to good adherence and log-term persistence in patients who also often need to use other drugs, such as antidiabetic agents, statins or antiplatelet agents. The fixed combinations of three antihypertensive agents currently available can facilitate long-term control of these patients in clinical practice. If well tolerated, a long-term therapeutic regimen that includes a diuretic, an ACE inhibitor or an angiotensin receptor blocker, and a calcium channel blocker is the recommended optimal triple therapy.

  15. Radiobiological speculations on therapeutic total body irradiation

    International Nuclear Information System (INIS)

    Vriesendorp, H.M.

    1990-01-01

    Unexpected total body irradiation (TBI) of human beings, involved in nuclear warfare or in accidents in nuclear reactors can be lethal. In the 1950s, bone marrow transplantation was discovered as a potentially life saving procedure after TBI in the dose range of 5.0 to 12.0 Gy. Since that time, deliberate or therapeutic TBI has been used to condition patients with a lethal bone marrow disorder for bone marrow replacement. The therapeutic ratio of TBI followed by bone marrow transplantation is small. Many potentially lethal complications can occur, such as acute TBI side effects, late TBI side effects or immunological complications of bone marrow transplantation such as graft versus host disease or graft rejection. The benefits of TBI and bone marrow transplantation are that they offer a chance for cure of previously lethal bone marrow disorders. The optimal parameters for TBI remain to be defined. The review discusses the current clinical and experimental animal data, as they relate to the future definition of less toxic TBI procedures with a better therapeutic ratio. Different TBI procedures are required for patients with malignant vs. non-malignant disorders or for patients with histoincompatible vs. histocompatible bone marrow donors.77 references

  16. Therapeutic Value of the Periodic Health Examination

    Energy Technology Data Exchange (ETDEWEB)

    Lincoln, T. A.; Hurt, H. B.

    1965-09-01

    The Oak Ridge National Laboratory has been conducting periodic health examinations on all of its employees for over 10 years. The original purpose of this program was the early detection of disease to be followed by referral or appropriate counseling. Because of the relatively young age of this group, we expected that this service would be of greatest benefit to only the small percentage who had significant findings. However, over this 10 year period we have been increasingly impressed that those who had no significant findings have expressed almost as much enthusiasm and gratitude as those in whom we found early but potentially serious disease. This response caused us to look more critically at the reasons for this favorable reaction. As a result, we have become convinced that these examinations have an important therapeutic value to the healthy, as well as the sick, and that this fact should be considered in their justification. A health examination can quite properly be considered therapeutic, even though no disease is found or treated, providing it "serves" or meets some of the needs of the person being examined. After all, the literal definition of the word therapeutic is service, since it is derived from the Greek word therapeutikos, which means an attendant or servant.

  17. The therapeutic alliance: a psychoanalytic perspective.

    Science.gov (United States)

    Freebury, D R

    1989-11-01

    Psychoanalysis has long distinguished between the transference neurosis and that part of the communication between therapist and patient which depends upon a relatively intact part of the patient's ego. It has been proposed that it is this capacity of the patient that sustains the difficult work of dealing with communications which are the consequence of transference, and which often threaten the viability of the treatment. This quality has been referred to variously as the unobjectionable positive transference, rational transference, mature transference, therapeutic alliance and working alliance. The ever broadening scope of Psychoanalysis, along with our greater knowledge of early childhood development, has enhanced our understanding of the many influences affecting the treatment alliances. Newer views of the transference, which stress the significance of the therapists' contributions to the therapeutic dyad, make it clear that the therapeutic alliance can no longer be explained as some simple, reality based, conflict free, motivating force. It involves, rather, a complex interaction of several factors, to each of which one must add the therapists' reciprocal reactions. Psychotherapy outcome research will need to take all of these factors into consideration.

  18. Engineering responsive supramolecular biomaterials: Toward smart therapeutics.

    Science.gov (United States)

    Webber, Matthew J

    2016-09-01

    Engineering materials using supramolecular principles enables generalizable and modular platforms that have tunable chemical, mechanical, and biological properties. Applying this bottom-up, molecular engineering-based approach to therapeutic design affords unmatched control of emergent properties and functionalities. In preparing responsive materials for biomedical applications, the dynamic character of typical supramolecular interactions facilitates systems that can more rapidly sense and respond to specific stimuli through a fundamental change in material properties or characteristics, as compared to cases where covalent bonds must be overcome. Several supramolecular motifs have been evaluated toward the preparation of "smart" materials capable of sensing and responding to stimuli. Triggers of interest in designing materials for therapeutic use include applied external fields, environmental changes, biological actuators, applied mechanical loading, and modulation of relative binding affinities. In addition, multistimuli-responsive routes can be realized that capture combinations of triggers for increased functionality. In sum, supramolecular engineering offers a highly functional strategy to prepare responsive materials. Future development and refinement of these approaches will improve precision in material formation and responsiveness, seek dynamic reciprocity in interactions with living biological systems, and improve spatiotemporal sensing of disease for better therapeutic deployment.

  19. Supramolecular Nanoparticles for Molecular Diagnostics and Therapeutics

    Chen, Kuan-Ju

    Over the past decades, significant efforts have been devoted to explore the use of various nanoparticle-based systems in the field of nanomedicine, including molecular imaging and therapy. Supramolecular synthetic approaches have attracted lots of attention due to their flexibility, convenience, and modularity for producing nanoparticles. In this dissertation, the developmental story of our size-controllable supramolecular nanoparticles (SNPs) will be discussed, as well as their use in specific biomedical applications. To achieve the self-assembly of SNPs, the well-characterized molecular recognition system (i.e., cyclodextrin/adamantane recognition) was employed. The resulting SNPs, which were assembled from three molecular building blocks, possess incredible stability in various physiological conditions, reversible size-controllability and dynamic disassembly that were exploited for various in vitro and in vivo applications. An advantage of using the supramolecular approach is that it enables the convenient incorporation of functional ligands onto SNP surface that confers functionality ( e.g., targeting, cell penetration) to SNPs. We utilized SNPs for molecular imaging such as magnetic resonance imaging (MRI) and positron emission tomography (PET) by introducing reporter systems (i.e., radio-isotopes, MR contrast agents, and fluorophores) into SNPs. On the other hand, the incorporation of various payloads, including drugs, genes and proteins, into SNPs showed improved delivery performance and enhanced therapeutic efficacy for these therapeutic agents. Leveraging the powers of (i) a combinatorial synthetic approach based on supramolecular assembly and (ii) a digital microreactor, a rapid developmental pathway was developed that is capable of screening SNP candidates for the ideal structural and functional properties that deliver optimal performance. Moreover, SNP-based theranostic delivery systems that combine reporter systems and therapeutic payloads into a

    Baltazar, M; Conty, L

    2016-12-01

    The perception of a direct gaze - that is, of another individual's gaze directed at the observer that leads to eye contact - is known to influence a wide range of cognitive processes and behaviors. We stress that these effects mainly reflect positive impacts on human cognition and may thus be used as relevant tools for therapeutic purposes. In this review, we aim (1) to provide an exhaustive review of eye contact effects while discussing the limits of the dominant models used to explain these effects, (2) to illustrate the therapeutic potential of eye contact by targeting those pathologies that show both preserved gaze processing and deficits in one or several functions that are targeted by the eye contact effects, and (3) to propose concrete ways in which eye contact could be employed as a therapeutic tool. (1) We regroup the variety of eye contact effects into four categories, including memory effects, activation of prosocial behavior, positive appraisals of self and others and the enhancement of self-awareness. We emphasize that the models proposed to account for these effects have a poor predictive value and that further descriptions of these effects is needed. (2) We then emphasize that people with pathologies that affect memory, social behavior, and self and/or other appraisal, and self-awareness could benefit from eye contact effects. We focus on depression, autism and Alzheimer's disease to illustrate our proposal. To our knowledge, no anomaly of eye contact has been reported in depression. Patients suffering from Alzheimer disease, at the early and moderate stage, have been shown to maintain a normal amount of eye contact with their interlocutor. We take into account that autism is controversial regarding whether gaze processing is preserved or altered. In the first view, individuals are thought to elude or omit gazing at another's eyes while in the second, individuals are considered to not be able to process the gaze of others. We adopt the first stance

  1. Achieving the Promise of Therapeutic Extracellular Vesicles: The Devil is in Details of Therapeutic Loading.

    2017-05-01

    Extracellular vesicles (EVs) represent a class of cell secreted organelles which naturally contain biomolecular cargo such as miRNA, mRNA and proteins. EVs mediate intercellular communication, enabling the transfer of functional nucleic acids from the cell of origin to the recipient cells. In addition, EVs make an attractive delivery vehicle for therapeutics owing to their increased stability in circulation, biocompatibility, low immunogenicity and toxicity profiles. EVs can also be engineered to display targeting moieties on their surfaces which enables targeting to desired tissues, organs or cells. While much has been learned on the role of EVs as cell communicators, the field of therapeutic EV application is currently under development. Critical to the future success of EV delivery system is the description of methods by which therapeutics can be successfully and efficiently loaded within the EVs. Two methods of loading of EVs with therapeutic cargo exist, endogenous and exogenous loading. We have therefore focused this review on describing the various published approaches for loading EVs with therapeutics.

    2013-01-01

    Cancer is the second leading cause of death in the United States. Conventional therapies cause widespread systemic toxicity and lead to serious side effects which prohibit their long term use. Additionally, in many circumstances tumor resistance and recurrence is commonly observed. Therefore, there is an urgent need to identify suitable anticancer therapies that are highly precise with minimal side effects. Curcumin is a natural polyphenol molecule derived from the Curcuma longa plant which exhibits anticancer, chemo-preventive, chemo- and radio-sensitization properties. Curcumin’s widespread availability, safety, low cost and multiple cancer fighting functions justify its development as a drug for cancer treatment. However, various basic and clinical studies elucidate curcumin’s limited efficacy due to its low solubility, high rate of metabolism, poor bioavailability and pharmacokinetics. A growing list of nanomedicine(s) using first line therapeutic drugs have been approved or are under consideration by the Food and Drug Administration (FDA) to improve human health. These nanotechnology strategies may help to overcome challenges and ease the translation of curcumin from bench to clinical application. Prominent research is reviewed which shows that advanced drug delivery of curcumin (curcumin nanoformulations or curcumin nanomedicine) is able to leverage therapeutic benefits by improving bioavailability and pharmacokinetics which in turn improves binding, internalization and targeting of tumor(s). Outcomes using these novel drug delivery systems have been discussed in detail. This review also describes the tumor-specific drug delivery system(s) that can be highly effective in destroying tumors. Such new approaches are expected to lead to clinical trials and to improve cancer therapeutics. PMID:23116309

  4. An Enhanced Understanding of Therapeutic Communities Worldwide.

    Therapeutic communities posit favorable treatment outcomes by relying on the community as the healing agent (Deleon 2000). Active treatment participation and treatment tenure are two domains that are positive predictors of positive treatment outcomes over time. Some of the more important domains that remain to be thoroughly investigated in international research on therapeutic community (TC) treatment outcome studies are the underlying effects of culture on the treatment process. Cultural components play a significant role, as also reported by various TC participants over the years (such as the effects of health literacy on sustaining abstinence from drug use over the long term, Tiburcio 2008). In recent years, health literacy has taken on a significant role in order for individuals to readily understand their needs (Schillinger et al 2002; Jorm et al 1997); or as pertains to feeling shamed in the process (Parikh et al 1996). As these and other studies suggest, the cultural competence of the providers is equally important. To our knowledge the " International TC Study " and findings presented herein constitute one of only a few studies that have conducted investigations comparing therapeutic community treatment modifications internationally, from the perspective of the participants themselves and which consider cultural components of this process. One key advantage of the resulting Qualitative datasets and analyses is that it not only includes residents' perspectives, and staff experiential elements, but importantly, incorporates staff debriefings about their respective interactions at each of the international treatment modalities, presenting well rounded depictions of each of these milieus. To that end, the data examined here presents an enhanced portrait of the provider-patient treatment dynamic, and lends voice to the various aspects of treatment participation in light of these cultural issues, and from the perspective of providers, as well as the participants.

  5. Colorectal cancer: diagnostic and therapeutic strategies

    Vaillant, J.C.

    1996-01-01

    Technical advances that has been achieved during the past two decades have not dramatically improved the 35 % five-year rate observed in patients with colorectal cancer. These tumours remain one of the most challenging problems in public health policies in western countries. Screening applies to some subgroups of high-risk individuals and the general population aged over 50. In order to improve their efficacy, such screening programs imply large-scale information campaigns and a strong cooperation with the general physicians. The diagnosis is strongly suggested by any recent modification of bowel habits ad by rectal bleeding. It has to be confirmed by rectal examination and by colonoscopy which allows sampling to the tumour. Loco-regional and distant metastatic tumour spread must be assessed precisely before any therapeutic strategy is decided. Surgery, which resects the tumour en bloc with the corresponding lymphatic territories, is the only treatment that can achieve long term cure. In localized tumours, surgery alone can provide patients with 5-years survival rates close to 95 %. On the other hand, surgery alone is not sufficient to cure patients with advances cancers. In recent years, several adjuvant therapeutic modalities have been shown to improve the results of surgery in these cases (rectal cancer: pre-operative radiotherapy or post-operative radio-chemotherapy, colon cancer with nodal metastases: post-operative chemotherapy). There is a hope that a better use of our diagnostic and therapeutic armementarium would be able to avoid or to cure up to 75 % of the colorectal cancers we are dealing with. (author)

    2016-12-01

    Full Text Available The ultimate goal of treating rheumatic disease is to achieve rapid suppression of inflammation, while at the same time minimizing the toxicities from rheumatic drugs. Different patients have different individual pharmacokinetics that can affect the drug level. Moreover, different factors, such as renal function, age or even different underlying diseases, can affect the drug level. Therefore, giving the same dosage of drugs to different patients may result in different drug levels. This article will review the usefulness of therapeutic drug monitoring in maximizing drug efficacy, while reducing the risk of toxicities in Hydroxychloroquine, Mycophenolate Mofetil, Tacrolimus and Tumor Necrosis Factor inhibitors (TNF Inhibitors.

    2016-01-04

    In this review, I will consider the dual nature of Cannabis and cannabinoids. The duality arises from the potential and actuality of cannabinoids in the laboratory and clinic and the 'abuse' of Cannabis outside the clinic. The therapeutic areas currently best associated with exploitation of Cannabis-related medicines include pain, epilepsy, feeding disorders, multiple sclerosis and glaucoma. As with every other medicinal drug of course, the 'trick' will be to maximise the benefit and minimise the cost. After millennia of proximity and exploitation of the Cannabis plant, we are still playing catch up with an understanding of its potential influence for medicinal benefit.

    2004-01-01

    This article is a critical examination of the science and ethics of human cloning. It summarises the key scientific milestones in the development of nuclear transplantation, explains the importance of cloning to research into the medical potential of embryonic stem cells, and discusses the well-worn distinction between 'therapeutic' and 'reproductive' cloning. Suggesting that this distinction will be impossible to police, it goes on to consider the ethics of full human cloning. It is concluded that it represents an unacceptable form of parental despotism, and that the genetic engineering and cloning of future human beings will fracture the foundations of modern humanism.

    Models of the psychoanalytic situation can usefully be thought of as fictions. Viewed this way, the models can be understood as narrative structures that shape what we are able to see and how we are able to think about what happens between us and our analysands. Theories of therapeutic action are elements of what can be called a "controlling fiction," mediating between these theories and our very real responsibilities, both to our preferred method and to a suffering patient. This venture into comparative psychoanalysis is illustrated by a discussion of published case material. © 2015 by the American Psychoanalytic Association.

    Acquired deformations of spinal cord (scoliosis, kyphosis, lordosis) represent a frequent pathology in child; their treatment is complex, with variable results which depend on various parameters. Mild scoliosis, with an angle less than 30 degrees, is treated with physiotherapy and regular follow-up. If the angle is higher than 30 degrees, the orthopedic corset is required; the angle over 45 degrees impose surgically correction. The indications of every therapeutic method depend on many factors, the main target of the treatment is to prevent the aggravation of the curvature; concerning the surgery, the goal is to obtain a correction as normal as possible of the spinal axis.

    The invention is a real time sensor for therapeutic radiation. A probe is placed in or near the patient that senses in real time the dose at the location of the probe. The strength of the dose is determined by either an insertion or an exit probe. The location is determined by a series of vertical and horizontal sensing elements that gives the operator a real time read out dose location relative to placement of the patient. The increased accuracy prevents serious tissue damage to the patient by preventing overdose or delivery of a dose to a wrong location within the body. 14 figs

    Recurrent vulvovaginitis is a common problem in clinical practice. Management is often complicated by a long history of inappropriate treatments based on tentative diagnoses after an incomplete diagnostic workup. We review the most common causes of recurrent vulvovaginitis; the appropriate steps with which to establish a diagnosis, from the medical history through to the additional tests needed; and, finally, the best therapeutic options. We will focus on infectious, irritant, allergic, and hormonal causes as the ones of most interest to the dermatologist. Given that infection is the most frequent cause of these processes and also a common reason for inopportune treatment, we will pay particular attention to infectious etiologies and their differential diagnosis.

    2015-01-01

    The rapidly evolving science of epigenetics is transforming our understanding of the nervous system in health and disease and holds great promise for the development of novel diagnostic and therapeutic approaches targeting neurological diseases. Increasing evidence suggests that epigenetic factors and mechanisms serve as important mediators of the pathogenic processes that lead to irrevocable neural injury and of countervailing homeostatic and regenerative responses. Epigenetics is, therefore, of considerable translational significance to the field of neuroprotection. In this brief review, we provide an overview of epigenetic mechanisms and highlight the emerging roles played by epigenetic processes in neural cell dysfunction and death and in resultant neuroprotective responses.

    A recent revolution in RNA biology has led to the identification of new RNA classes with unanticipated functions, new types of RNA modifications, an unexpected multiplicity of alternative transcripts and widespread transcription of extragenic regions. This development in basic RNA biology has spawned a corresponding revolution in RNA-based strategies to generate new types of therapeutics. Here, I review RNA-based drug design and discuss barriers to broader applications and possible ways to overcome them. Because they target nucleic acids rather than proteins, RNA-based drugs promise to greatly extend the domain of 'druggable' targets beyond what can be achieved with small molecules and biologics.

    Growing evidence supporting the effectiveness of Collaborative/Therapeutic Assessment (C/TA) has led clinicians and researchers to apply C/TA to a variety of clinical populations and treatment settings. This case example presents a C/TA inpatient adaptation illustrated with narcissistic personality disorder. After a brief overview of salient concepts, I provide a detailed account of the clinical interview, test interpretation paired with diagnostic considerations specific to narcissism, planned intervention, and discussion of assessment results. Throughout the case study, I attempt to demonstrate defining features of C/TA, inpatient adaptations, and clinical techniques that encourage meaningful engagement with a "hard to reach" personality.

  3. New concepts in therapeutic photomedicine: photochemistry, optical targeting and the therapeutic window

    International Nuclear Information System (INIS)

    Parrish, J.A.

    1981-01-01

    Advances in optics technology, synthetic photochemistry, and the science of photobiology make it possible to think beyond phototherapy and photochemotherapy which is dependent on direct photochemical alteration of metabolites or direct phototoxic insult to cells. This report discusses another gender of photomedicine therapy which includes in vivo photoactivation of medicines, photon-dependent drug delivery, and manipulation of host and exposure source to maximize therapeutic index. These therapeutic manipulations are made possible because the skin is highly overperfused and because non-ionizing electromagnetic radiation that enters skin and blood has adequate photon energy to cause electronic excitation. Radiation of 320-800 nm is not very directly phototoxic, is absorbed by a variety of relatively nontoxic photolabile molecules and has an internal dosimetric depth profile. This radiation can therefore be used to activate, deactivate, bind, release or biotransform medications in vivo in skin or other organs. The photochemist, synthetic chemist and photobiologist can collaborate to significantly increase therapeutic possibilities

    Harnessing nature to promote mental health is increasingly seen as a sustainable solution to healthcare across the industrialised world. The benefits of these approaches to well-being include reduced symptoms of anxiety, depression and improved social functioning. Many studies assume that contact with nature is the main therapeutic component of these interventions yet 'green care' programmes typically include activities not based on 'nature' that may contribute to positive outcomes. This study explored the views of service users participating in a Therapeutic Horticultural programme on what factors promoted their engagement in the project, to identify variables other than 'nature' that may be responsible for successful engagement in these programmes. A secondary aim was to assess the significance 'nature' plays including, for example whether a prior interest in horticultural-related activities, such as gardening, is significant. Two focus groups were held with mental health service users (n = 15) attending a gardening project in south-east England. Findings revealed that the social element of the project was the key facilitator to engagement; the flexible structure of the gardening project was also significant and allowed service users to feel empowered. 'Nature' evoked a sense of calm and provided participants with a non-threatening space that was engaging. © 2017 John Wiley & Sons Ltd.

  10. Hypoxic conditioning as a new therapeutic modality

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Preconditioning refers to a procedure by which a single noxious stimulus below the threshold of damage is applied to the tissue in order to increase resistance to the same or even different noxious stimuli given above the threshold of damage. Hypoxic preconditioning relies on complex and active defenses that organisms have developed to counter the adverse consequences of oxygen deprivation. The protection it confers against ischemic attack for instance as well as the underlying biological mechanisms have been extensively investigated in animal models. Based on these data, hypoxic conditioning (consisting in recurrent exposure to hypoxia has been suggested a potential non-pharmacological therapeutic intervention to enhance some physiological functions in individuals in whom acute or chronic pathological events are anticipated or existing. In addition to healthy subjects, some benefits have been reported in patients with cardiovascular and pulmonary diseases as well as in overweight and obese individuals. Hypoxic conditioning consisting in sessions of intermittent exposure to moderate hypoxia repeated over several weeks may induce hematological, vascular, metabolic and neurological effects. This review addresses the existing evidence regarding the use of hypoxic conditioning as a potential therapeutic modality and emphasizes on many remaining issues to clarify and future researches to be performed in the field.

  11. Novel Therapeutic GPCRs for Psychiatric Disorders

    2015-06-01

    Full Text Available G protein-coupled receptors (GPCRs are the most common targets of the neuropharmacological drugs in the central nervous system (CNS. GPCRs are activated by manifold neurotransmitters, and their activation in turn evokes slow synaptic transmission. They are deeply involved in multiple neurological and psychiatric disorders such as Parkinson’s disease and schizophrenia. In the brain, the striatum is strongly innervated by the ventral tegmental area (VTA and plays a central role in manifestation of psychiatric disorders. Recently, anatomical and comprehensive transcriptome analysis of the non-odorant GPCR superfamily revealed that the orphan GPCRs GPR88, GPR6, and GPR52, as well as dopamine D1 and D2 receptors and the adenosine A2a receptor, are the most highly enriched in the rodent striatum. Genetically engineered animal models and molecular biological studies have suggested that these striatally enriched GPCRs have a potential to be therapeutic psychiatric receptors. This review summarizes the current understanding of the therapeutic GPCR candidates for psychiatric disorders.

    To determine the long-range psychological effects of therapeutic abortion, 50 women (aged from 13-44 years), who were granted abortions between 1967 and 1968 Because of possible impairment of mental and/or physical health, were analyzed by use of demographic questionnaires, psychological tests, and interviews. Testing revealed that 44 women had psychiatric problems at time of abortion. 43 patients were followed for 3-6 months. The follow-up interviews revealed that 29 patients reacted positively after abortion, 10 reported no significant change and 4 reacted negatively. 37 would definitely repeat the abortion. Women under 21 years of age felt substantially more ambivalent and guilty than older patients. A study of 36 paired pre- and post-abortion profiles showed that 15 initially abnormal tests had become normal. There was a significant increase in contraceptive use among the patients after the abortion, but 4 again became pregnant and 8 were apparently without consistent contraception. It is concluded that the abortions were therapeutic, but physicians are encouraged to be aware of psychological problems in abortion cases. Strong psychological and contraceptive counselling should be exercised.

  13. Thyroid abnormalities after therapeutic external radiation

    1995-01-01

    The thyroid gland is the largest pure endocrine gland in the body and one of the organs most likely to produce clinically significant abnormalities after therapeutic external radiation. Radiation doses to the thyroid that exceed approximately 26 Gy frequently produce hypothyroidism, which may be clinically overt or subclinical, as manifested by increased serum thyrotropin and normal serum-free thyroxine concentrations. Pituitary or hypothalamic hypothyroidism may arise when the pituitary region receives doses exceeding 50 Gy with conventional, 1.8-2 Gy fractionation. Direct irradiation of the thyroid may increase the risk of Graves' disease or euthyroid Graves' opthalmopathy. Silent thyroiditis, cystic degeneration, benign adenoma, and thyroid cancer have been observed after therapeutically relevant doses of external radiation. Direct or incidental thyroid irradiation increases the risk for well-differentiated, papillary, and follicular thyroid cancer from 15- to 53-fold. Thyroid cancer risk is highest following radiation at a young age, decreases with increasing age at treatment, and increases with follow-up duration. The potentially prolonged latent period between radiation exposure and the development of thyroid dysfunction, thyroid nodularity, and thyroid cancer means that individuals who have received neck or pituitary irradiation require careful, periodic clinical and laboratory evaluation to avoid excess morbidity

    Recent progress in understanding the molecular mechanisms of the initiation and progression of melanoma has created new opportunities for developing novel therapeutic modalities to manage this potentially lethal disease. Although at first glance, melanoma carcinogenesis appears to be a chaotic system, it is indeed, arguably, a deterministic multistep process involving sequential alterations of proto-oncogenes, tumour suppressors and miRNA genes. The scope of this article is to discuss the most recent and significant advances in melanoma molecular therapeutics. It is apparent that using single agents targeting solely individual melanoma pathways might be insufficient for long-term survival. However, the outstanding results on melanoma survival observed with novel selective inhibitors of B-RAF, such as PLX4032 give hope that melanoma can be cured. The fact that melanoma develops acquired resistance to PLX4032 emphasises the importance of simultaneously targeting several pathways. Because the most striking feature of melanoma is its unsurpassed ability to metastasise, it is important to implement newer systems for drug delivery adapted from research on stem cells and nanotechnology.

    Previous studies have identified relevant genes and signalling pathways that are hampered in human disorders as potential candidates for therapeutics. Developing nucleic acid-based tools to manipulate gene expression, such as short interfering RNAs 1-3 (siRNAs), opens up opportunities for personalized medicine. Yet, although major progress has been made in developing siRNA targeted delivery carriers, mainly by utilizing monoclonal antibodies (mAbs) for targeting 4-8 , their clinical translation has not occurred. This is in part because of the massive development and production requirements and the high batch-to-batch variability of current technologies, which rely on chemical conjugation. Here we present a self-assembled modular platform that enables the construction of a theoretically unlimited repertoire of siRNA targeted carriers. The self-assembly of the platform is based on a membrane-anchored lipoprotein that is incorporated into siRNA-loaded lipid nanoparticles that interact with the antibody crystallizable fragment (Fc) domain. We show that a simple switch of eight different mAbs redirects the specific uptake of siRNAs by diverse leukocyte subsets in vivo. The therapeutic potential of the platform is demonstrated in an inflammatory bowel disease model by targeting colon macrophages to reduce inflammatory symptoms, and in a Mantle Cell Lymphoma xenograft model by targeting cancer cells to induce cell death and improve survival. This modular delivery platform represents a milestone in the development of precision medicine.

    Cucumber (Cucumis sativus L.) is a member of the Cucurbitaceae family like melon, squash and pumpkins. It is a popular vegetable crop used in Indian traditional medicine since ancient times. This vegetable is very high in water content and very low in calories. It has potential antidiabetic, lipid lowering and antioxidant activity. Cucumber has a cleansing action within the body by removing accumulated pockets of old waste materials and chemical toxins. Fresh fruit juice is used for nourishing the skin. It gives a soothing effect against skin irritations and reduces swelling. Cucumber also has the power to relax and alleviate the sunburn's pain. The fruit is refrigerant, haemostatic, tonic and useful in hyperdipsia, thermoplegia etc. The seeds also have a cooling effect on the body and they are used to prevent constipation. Several bioactive compounds have been isolated from cucumber including cucurbitacins, cucumegastigmanes I and II, cucumerin A and B, vitexin, orientin, isoscoparin 2″-O-(6‴-(E)-p-coumaroyl) glucoside, apigenin 7-O-(6″-O-p-coumaroylglucoside) etc. Despite huge exploration of cucumber in agricultural field, comparatively very few studies have been published about its chemical profile and its therapeutic potential. This article reviews the therapeutic application, pharmacological and phytochemical profile of different parts of C. sativus. In this review we have explored the current phytochemical and pharmacological knowledge available with this well known plant and several promising aspects for research on cucumber.

  18. [Pathogenetic and therapeutic aspects of secondary anorexia].

    Laviano, A; Cascino, A; Muscaritoli, M; Rossi Fanelli, F

    2000-01-01

    Anorexia is an often underrated symptom in the clinical management of patients suffering from chronic diseases. Moreover, the anorexia accompanying chronic diseases (secondary anorexia) is often confused with anorexia nervosa, a typically neuropsychiatric disorder involving completely different pathogenic mechanisms and therapeutic strategies. Secondary anorexia is one of the main factors responsible for the development of malnutrition, which in turn negatively affects patient morbidity and mortality. Different mechanisms have been proposed to explain the pathogenesis of secondary anorexia. However, consistent experimental and clinical evidence seems to point to hypothalamic serotonergic system hyperactivity as a preeminent cause; this hyperactivity appears to be triggered by enhanced brain availability of tryptophan, the aminoacid precursor of serotonin. The hyperactive hypothalamic serotonergic system might also represent the final effector where different regulatory and modulating pathways, including cytokines, converge. The involvement of tryptophan and the hypothalamic serotonergic system is further supported by the effectiveness of a therapeutic strategy, based on the inhibition of tryptophan entry into the brain, in increasing the food intake of anorectic patients. Although these results represent an encouraging approach to the treatment of secondary anorexia, with possible beneficial effects on the nutritional status of patients, they need to be validated in larger trials.

    Full Text Available Stroke represents one of the major causes of death and disability worldwide, for which no effective treatments are available. The thrombolytic drug alteplase (tissue plasminogen activator or tPA is the only treatment for acute ischemic stroke but its use is limited by several factors including short therapeutic window, selective efficacy and subsequent haemorrhagic complications. Numerous preclinical studies have reported very promising results using neuroprotective agents but they have failed at clinical trials because of either safety issues or lack of efficacy. The delivery of many potentially therapeutic neuroprotectants and diagnostic compounds to the brain is restricted by the blood-brain barrier (BBB. Nanoparticles (NPs, which can readily cross the BBB without compromising its integrity, have immense applications in the treatment of ischemic stroke. In this review, potential uses of NPs will be summarized for the treatment of ischemic stroke. Additionally, an overview of targeted NPs will be provided, which could be used in the diagnosis of stroke. Finally, the potential limitations of using NPs in medical applications will be mentioned. Since the use of NPs in stroke therapy is now emerging and is still in development, this review is far from comprehensive or conclusive. Instead, examples of NPs and their current use will be provided, as well as the potentials of NPs in an effort to meet the high demand of new therapies in stroke.

    Lasers have found application in diverse branches of medicine. In ophthalmology, laser technology has various therapeutic and diagnostic applications. The purpose of this article is to review the major therapeutic applications of lasers in different eye disorders. The effects of lasers on biological tissues and different laser techniques as well as the indications for laser therapy in various parts of the eye are discussed. Lasers are used to treat glaucoma and many vascular disorders of the retina. Laser treatment may be useful in preventing the development of neovascularization in diabetic retinopathy, BRVO, or CRVO. Laser techniques are also available for the treatment of the exudative form of age-related macular degeneration (AMD) and some malignant and benign intraocular tumors and in retina abnormalities which predispose to rhegmatogenous retinal detachment. Corneal laser surgery is the most frequently applied laser procedure in ophthalmology. PRK, LASIK, and LASEK are used to correct errors in vision such as myopia, hyperopia, and astigmatism. Laser photocoagulation is also helpful in cataract surgery. Nowadays, lasers have become so universal that it is difficult to imagine ophthalmology without them. We are still witnessing rapid advances in the development of laser techniques, especially in plastic surgery, cataract extraction, and ocular imaging. (authors)

    Huntington's disease (HD) is a degenerative dysfunction of hereditary origin. Up to date there is not, an effective treatment to the disease which having lapsed 15 or 20 years advances inexorably, in a slow form, toward the total inability or death. This paper reviews the clinical and morphological characteristics of Huntington's disease as well as the experimental models more commonly used to study this disease, having as source the articles indexed in Medline data base, published in the last 20 years. Advantages and disadvantages of all experimental models to reproduce the disease as well as the perspectives to therapeutic assay have been also considered. the consent of outline reported about the toxic models, those induced by neurotoxins such as quinolinic acid, appears to be the most appropriate to reproduce the neuropathologic characteristic of the disease, an genetic models contributing with more evidence to the knowledge of the disease etiology. Numerous treatments ameliorate clinical manifestations, but none of them has been able to stop or diminish the affectations derived from neuronal loss. At present time it is possible to reproduce, at least partially, the characteristics of the disease in experimentation animals that allow therapy evaluation in HD. from the treatment view point, the more promissory seems to be transplantation of no neuronal cells, taking into account ethical issues and factibility. On the other hand the new technology of interference RNA emerges as a potential therapeutic tool for treatment in HD, and to respond basic questions on the development of the disease.

    Full Text Available Science always strives to find an improved way of doing things and nanoscience is one such approach. Nanomaterials are suitable for pharmaceutical applications mostly because of their size which facilitates absorption, distribution, metabolism and excretion of the nanoparticles. Whether labile or insoluble nanoparticles, their cytotoxic effect on malignant cells has moved the use of nanomedicine into focus. Since nanomedicine can be described as the science and technology of diagnosing, treating and preventing diseases towards ultimately improving human health, a lot of nanotechnology options have received approval by various regulatory agencies. Nanodrugs also have been discovered to be more precise in targeting the desired site, hence maximizing the therapeutic effects, while minimizing side-effects on the rest of the body. This unique property and more has made nanomedicine popular in therapeutic medicine employing nanotechnology in genetic therapy, drug encapsulation, enzyme manipulation and control, tissue engineering, target drug delivery, pharmacogenomics, stem cell and cloning, and even virus-based hybrids. This review highlights nanoproducts that are in development and have gained approval through one clinical trial stage or the other.

    Full Text Available This study reviews the literature concerning possible therapeutic approaches for spinal cord injury. Spinal cord injury is a disabling and irreversible condition that has high economic and social costs. There are both primary and secondary mechanisms of damage to the spinal cord. The primary lesion is the mechanical injury itself. The secondary lesion results from one or more biochemical and cellular processes that are triggered by the primary lesion. The frustration of health professionals in treating a severe spinal cord injury was described in 1700 BC in an Egyptian surgical papyrus that was translated by Edwin Smith; the papyrus reported spinal fractures as a ''disease that should not be treated.'' Over the last biological or pharmacological treatment method. Science is unraveling the mechanisms of cell protection and neuroregeneration, but clinically, we only provide supportive care for patients with spinal cord injuries. By combining these treatments, researchers attempt to enhance the functional recovery of patients with spinal cord injuries. Advances in the last decade have allowed us to encourage the development of experimental studies in the field of spinal cord regeneration. The combination of several therapeutic strategies should, at minimum, allow for partial functional recoveries for these patients, which could improve their quality of life.

    Botulinum toxins (BoNTs) are produced by several anaerobic species of the genus Clostridium and, although they were originally considered lethal toxins, today they find their usefulness in the treatment of a wide range of pathologies in various medical specialties. Botulinum neurotoxin has been identified in seven different isoforms (BoNT-A, BoNT-B, BoNT-C, BoNT-D, BoNT-E, BoNT-F, and BoNT-G). Neurotoxigenic Clostridia can produce more than 40 different BoNT subtypes and, recently, a new BoNT serotype (BoNT-X) has been reported in some studies. BoNT-X has not been shown to actually be an active neurotoxin despite its catalytically active LC, so it should be described as a putative eighth serotype. The mechanism of action of the serotypes is similar: they inhibit the release of acetylcholine from the nerve endings but their therapeutically potency varies. Botulinum toxin type A (BoNT-A) is the most studied serotype for therapeutic purposes. Regarding the gynecological pathology, a series of studies based on the efficiency of its use in the treatment of refractory myofascial pelvic pain, vaginism, dyspareunia, vulvodynia and overactive bladder or urinary incontinence have been reported. The current study is a review of the literature regarding the efficiency of BoNT-A in the gynecological pathology and on the long and short-term effects of its administration.

    Ondansetron (GR 38032F) is a highly selective 5-HT3 receptor antagonist, one of a new class of compounds which may have several therapeutic applications. Animal and clinical studies show that ondansetron reduces the 24-hour incidence and severity of nausea and vomiting induced by cytotoxic drugs, including cisplatin, and by single exposure, high dose radiation. Ondansetron is more effective than high dose metoclopramide in the 24 hours following chemotherapy, and preliminary clinical evidence suggests that it is equally effective in the following 4 days. It is also more effective than the moderate doses of metoclopramide used to suppress emesis following radiotherapy. The antiemetic efficacy of ondansetron is enhanced by dexamethasone in cisplatin-treated patients. Importantly, extrapyramidal effects have not been reported with ondansetron. Further comparisons are required with standard combination antiemetic therapy to complement the data presently available. Thus, ondansetron is a promising new agent for prophylaxis against nausea and vomiting in chemotherapy and radiotherapy. It may be particularly useful in young and elderly patients who are more susceptible to extrapyramidal symptoms induced by high dose metoclopramide. With its improved tolerability and clinical response profiles, ondansetron represents an important advance in a difficult area of therapeutics. 101 refs.

    A large proportion of biomedical research and the development of therapeutics is focused on a small fraction of the human genome. In a strategic effort to map the knowledge gaps around proteins encoded by the human genome and to promote the exploration of currently understudied, but potentially druggable, proteins, the US National Institutes of Health launched the Illuminating the Druggable Genome (IDG) initiative in 2014. In this article, we discuss how the systematic collection and processing of a wide array of genomic, proteomic, chemical and disease-related resource data by the IDG Knowledge Management Center have enabled the development of evidence-based criteria for tracking the target development level (TDL) of human proteins, which indicates a substantial knowledge deficit for approximately one out of three proteins in the human proteome. We then present spotlights on the TDL categories as well as key drug target classes, including G protein-coupled receptors, protein kinases and ion channels, which illustrate the nature of the unexplored opportunities for biomedical research and therapeutic development.

    Science.gov (United States)

    Gilhus, Nils Erik; Verschuuren, Jan J

    2015-10-01

    Myasthenia gravis is an autoimmune disease that is characterised by muscle weakness and fatigue, is B-cell mediated, and is associated with antibodies directed against the acetylcholine receptor, muscle-specific kinase (MUSK), lipoprotein-related protein 4 (LRP4), or agrin in the postsynaptic membrane at the neuromuscular junction. Patients with myasthenia gravis should be classified into subgroups to help with therapeutic decisions and prognosis. Subgroups based on serum antibodies and clinical features include early-onset, late-onset, thymoma, MUSK, LRP4, antibody-negative, and ocular forms of myasthenia gravis. Agrin-associated myasthenia gravis might emerge as a new entity. The prognosis is good with optimum symptomatic, immunosuppressive, and supportive treatment. Pyridostigmine is the preferred symptomatic treatment, and for patients who do not adequately respond to symptomatic therapy, corticosteroids, azathioprine, and thymectomy are first-line immunosuppressive treatments. Additional immunomodulatory drugs are emerging, but therapeutic decisions are hampered by the scarcity of controlled studies. Long-term drug treatment is essential for most patients and must be tailored to the particular form of myasthenia gravis. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Ayahuasca is the Quechua name for a tea obtained from the vine Banisteriopsis caapi, and used for ritual purposes by the indigenous populations of the Amazon. The use of a variation of the tea that combines B. caapi with the leaves of the shrub Psychotria viridis has experienced unprecedented expansion worldwide for its psychotropic properties. This preparation contains the psychedelic 5-HT 2A receptor agonist N,N-dimethyltryptamine (DMT) from P. viridis, plus β-carboline alkaloids with monoamine-oxidase-inhibiting properties from B. caapi. Acute administration induces a transient modified state of consciousness characterized by introspection, visions, enhanced emotions and recollection of personal memories. A growing body of evidence suggests that ayahuasca may be useful to treat substance use disorders, anxiety and depression. Here we review the pharmacology and neuroscience of ayahuasca, and the potential psychological mechanisms underlying its therapeutic potential. We discuss recent findings indicating that ayahuasca intake increases certain mindfulness facets related to acceptance and to the ability to take a detached view of one's own thoughts and emotions. Based on the available evidence, we conclude that ayahuasca shows promise as a therapeutic tool by enhancing self-acceptance and allowing safe exposure to emotional events. We postulate that ayahuasca could be of use in the treatment of impulse-related, personality and substance use disorders and also in the handling of trauma. More research is needed to assess the full potential of ayahuasca in the treatment of these disorders. Copyright © 2016 Elsevier Inc. All rights reserved.

  10. Therapeutic Uses of Triphala in Ayurvedic Medicine.

    Science.gov (United States)

    Peterson, Christine Tara; Denniston, Kate; Chopra, Deepak

    2017-08-01

    The aim of this article is to review the current literature on the therapeutic uses and efficacy of Triphala. Herbal remedies are among the most ancient medicines used in traditional systems of healthcare such as Ayurveda. Triphala, a well-recognized and highly efficacious polyherbal Ayurvedic medicine consisting of fruits of the plant species Emblica officinalis (Amalaki), Terminalia bellerica (Bibhitaki), and Terminalia chebula (Haritaki), is a cornerstone of gastrointestinal and rejuvenative treatment. A search of the PubMed database was conducted. In addition, numerous additional therapeutic uses described both in the Ayurvedic medical literature and anecdotally are being validated scientifically. In addition to laxative action, Triphala research has found the formula to be potentially effective for several clinical uses such as appetite stimulation, reduction of hyperacidity, antioxidant, anti-inflammatory, immunomodulating, antibacterial, antimutagenic, adaptogenic, hypoglycemic, antineoplastic, chemoprotective, and radioprotective effects, and prevention of dental caries. Polyphenols in Triphala modulate the human gut microbiome and thereby promote the growth of beneficial Bifidobacteria and Lactobacillus while inhibiting the growth of undesirable gut microbes. The bioactivity of Triphala is elicited by gut microbiota to generate a variety of anti-inflammatory compounds. This review summarizes recent data on pharmacological properties and clinical effects of Triphala while highlighting areas in need of additional investigation and clinical development.

  11. Cancer Stem Cell Plasticity Drives Therapeutic Resistance

    Directory of Open Access Journals (Sweden)

    Mary R. Doherty

    2016-01-01

    Full Text Available The connection between epithelial-mesenchymal (E-M plasticity and cancer stem cell (CSC properties has been paradigm-shifting, linking tumor cell invasion and metastasis with therapeutic recurrence. However, despite their importance, the molecular pathways involved in generating invasive, metastatic, and therapy-resistant CSCs remain poorly understood. The enrichment of cells with a mesenchymal/CSC phenotype following therapy has been interpreted in two different ways. The original interpretation posited that therapy kills non-CSCs while sparing pre-existing CSCs. However, evidence is emerging that suggests non-CSCs can be induced into a transient, drug-tolerant, CSC-like state by chemotherapy. The ability to transition between distinct cell states may be as critical for the survival of tumor cells following therapy as it is for metastatic progression. Therefore, inhibition of the pathways that promote E-M and CSC plasticity may suppress tumor recurrence following chemotherapy. Here, we review the emerging appreciation for how plasticity confers therapeutic resistance and tumor recurrence.

    Previous studies have identified relevant genes and signalling pathways that are hampered in human disorders as potential candidates for therapeutics. Developing nucleic acid-based tools to manipulate gene expression, such as short interfering RNAs1-3 (siRNAs), opens up opportunities for personalized medicine. Yet, although major progress has been made in developing siRNA targeted delivery carriers, mainly by utilizing monoclonal antibodies (mAbs) for targeting4-8, their clinical translation has not occurred. This is in part because of the massive development and production requirements and the high batch-to-batch variability of current technologies, which rely on chemical conjugation. Here we present a self-assembled modular platform that enables the construction of a theoretically unlimited repertoire of siRNA targeted carriers. The self-assembly of the platform is based on a membrane-anchored lipoprotein that is incorporated into siRNA-loaded lipid nanoparticles that interact with the antibody crystallizable fragment (Fc) domain. We show that a simple switch of eight different mAbs redirects the specific uptake of siRNAs by diverse leukocyte subsets in vivo. The therapeutic potential of the platform is demonstrated in an inflammatory bowel disease model by targeting colon macrophages to reduce inflammatory symptoms, and in a Mantle Cell Lymphoma xenograft model by targeting cancer cells to induce cell death and improve survival. This modular delivery platform represents a milestone in the development of precision medicine.

    Vaishya, Ravi; Khurana, Varun; Patel, Sulabh; Mitra, Ashim K

    2015-03-01

    Proteins are effective biotherapeutics with applications in diverse ailments. Despite being specific and potent, their full clinical potential has not yet been realized. This can be attributed to short half-lives, complex structures, poor in vivo stability, low permeability, frequent parenteral administrations and poor adherence to treatment in chronic diseases. A sustained release system, providing controlled release of proteins, may overcome many of these limitations. This review focuses on recent development in approaches, especially polymer-based formulations, which can provide therapeutic levels of proteins over extended periods. Advances in particulate, gel-based formulations and novel approaches for extended protein delivery are discussed. Emphasis is placed on dosage form, method of preparation, mechanism of release and stability of biotherapeutics. Substantial advancements have been made in the field of extended protein delivery via various polymer-based formulations over last decade despite the unique delivery-related challenges posed by protein biologics. A number of injectable sustained-release formulations have reached market. However, therapeutic application of proteins is still hampered by delivery-related issues. A large number of protein molecules are under clinical trials, and hence, there is an urgent need to develop new methods to deliver these highly potent biologics.

  14. Ondansetron. Therapeutic use as an antiemetic

    Milne, R.J.; Heel, R.C.

    1991-01-01

    Ondansetron (GR 38032F) is a highly selective 5-HT3 receptor antagonist, one of a new class of compounds which may have several therapeutic applications. Animal and clinical studies show that ondansetron reduces the 24-hour incidence and severity of nausea and vomiting induced by cytotoxic drugs, including cisplatin, and by single exposure, high dose radiation. Ondansetron is more effective than high dose metoclopramide in the 24 hours following chemotherapy, and preliminary clinical evidence suggests that it is equally effective in the following 4 days. It is also more effective than the moderate doses of metoclopramide used to suppress emesis following radiotherapy. The antiemetic efficacy of ondansetron is enhanced by dexamethasone in cisplatin-treated patients. Importantly, extrapyramidal effects have not been reported with ondansetron. Further comparisons are required with standard combination antiemetic therapy to complement the data presently available. Thus, ondansetron is a promising new agent for prophylaxis against nausea and vomiting in chemotherapy and radiotherapy. It may be particularly useful in young and elderly patients who are more susceptible to extrapyramidal symptoms induced by high dose metoclopramide. With its improved tolerability and clinical response profiles, ondansetron represents an important advance in a difficult area of therapeutics. 101 refs

  15. The therapeutic journey of benzimidazoles: a review.

    Bansal, Yogita; Silakari, Om

    2012-11-01

    Presence of benzimidazole nucleus in numerous categories of therapeutic agents such as antimicrobials, antivirals, antiparasites, anticancer, anti-inflammatory, antioxidants, proton pump inhibitors, antihypertensives, anticoagulants, immunomodulators, hormone modulators, CNS stimulants as well as depressants, lipid level modulators, antidiabetics, etc. has made it an indispensable anchor for development of new therapeutic agents. Varied substitutents around the benzimidazole nucleus have provided a wide spectrum of biological activities. Importance of this nucleus in some activities like, Angiotensin I (AT(1)) receptor antagonism and proton-pump inhibition is reviewed separately in literature. Even some very short reviews on biological importance of this nucleus are also known in literature. However, owing to fast development of new drugs possessing benzimidazole nucleus many research reports are generated in short span of time. So, there is a need to couple the latest information with the earlier information to understand the current status of benzimidazole nucleus in medicinal chemistry research. In the present review, various derivatives of benzimidazole with different pharmacological activities are described on the basis of substitution pattern around the nucleus with an aim to help medicinal chemists for developing an SAR on benzimidazole derived compounds for each activity. This discussion will further help in the development of novel benzimidazole compounds. Copyright © 2012 Elsevier Ltd. All rights reserved.

  16. Therapeutic working alliance: From a psychoanalitical to a pantheoretical conception

    Directory of Open Access Journals (Sweden)

    Peter Praper

    2004-05-01

    Full Text Available Although the concept of therapeutic working alliance was rooted in psychoanalysis, today it is more prominent in psychoanalytic psychotherapies than psychoanalysis. It is rather surprising that we cannot find the concept in the Laplanche and Pontalis Dictionary. During the last two decades a growing body of empirical research material on therapeutic working alliance was published, confirming the idea of the alliance as a separate dimension of therapeutic relationship with few recognisable components. The dimension of the therapeutic working alliance was examined in several approaches and proved as one of the most important therapeutic factors, regardless of the approach, and it has finally been accepted as a pantheoretical concept.

    Johnston, Celeste; Campbell-Yeo, Marsha; Rich, Bonnie; Whitley, Julie; Filion, Francoise; Cogan, Jennifer; Walker, Claire-Dominique

    2013-09-01

    Preterm neonates below 30 weeks' gestational age undergo numerous painful procedures. Many management approaches are not appropriate for this population. Therapeutic Touch, an alternative approach based on the theory of energy medicine, has been shown to promote physiological stability in preterm neonates and reduce pain in some adult studies. The objective was to determine whether Therapeutic Touch is efficacious in decreasing pain in preterm neonates. Infants Touch (n = 27) with infant behind curtains, leaving the curtained area for the heel lance, performed by another. In the sham condition (n = 28), the therapist stood by the incubator with hands by her side. The Premature Infant Pain Profile was used for pain response and time for heart rate to return to baseline for recovery. Heart rate variability and stress response were secondary outcomes. There were no group differences in any of the outcomes. Mean Premature Infant Pain Profile scores across 2 minutes of heel lance procedure in 30-second blocks ranged from 7.92 to 8.98 in the Therapeutic Touch group and 7.64 to 8.46 in the sham group. Therapeutic Touch given immediately before and after heel lance has no comforting effect in preterm neonates. Other effective strategies involving actual touch should be considered.

    2012-01-01

    Silk fibroin (SF) is a biopolymer with distinguishing features from many other bio- as well as synthetic polymers. From a biomechanical and drug delivery perspective, SF combines remarkable versatility for scaffolding (solid implants, hydrogels, threads, solutions), with advanced mechanical properties and good stabilization and controlled delivery of entrapped protein and small molecule drugs, respectively. It is this combination of mechanical and pharmaceutical features which render SF so exciting for biomedical applications. his pattern along with the versatility of this biopolymer have been translated into progress for musculoskeletal applications. We review the use and potential of silk fibroin for systemic and localized delivery of therapeutics in diseases affecting the musculoskeletal system. We also present future directions for this biopolymer as well as the necessary research and development steps for their achievement. PMID:22522139

    2014-01-01

    Throughout history, many different cultures have recognized the potential use of garlic for prevention and treatment of different diseases. Recent studies support the effects of garlic and its extracts in a wide range of applications. These studies raised the possibility of revival of garlic therapeutic values in different diseases. Different compounds in garlic are thought to reduce the risk for cardiovascular diseases, have anti-tumor and anti-microbial effects, and show benefit on high blood glucose concentration. However, the exact mechanism of all ingredients and their long-term effects are not fully understood. Further studies are needed to elucidate the pathophysiological mechanisms of action of garlic as well as its efficacy and safety in treatment of various diseases. PMID:25050296

  20. Antimicrobial Peptides for Therapeutic Applications: A Review

    Directory of Open Access Journals (Sweden)

    Tsogbadrakh Mishig-Ochir

    2012-10-01

    Full Text Available Antimicrobial peptides (AMPs have been considered as potential therapeutic sources of future antibiotics because of their broad-spectrum activities and different mechanisms of action compared to conventional antibiotics. Although AMPs possess considerable benefits as new generation antibiotics, their clinical and commercial development still have some limitations, such as potential toxicity, susceptibility to proteases, and high cost of peptide production. In order to overcome those obstacles, extensive efforts have been carried out. For instance, unusual amino acids or peptido-mimetics are introduced to avoid the proteolytic degradation and the design of short peptides retaining antimicrobial activities is proposed as a solution for the cost issue. In this review, we focus on small peptides, especially those with less than twelve amino acids, and provide an overview of the relationships between their three-dimensional structures and antimicrobial activities. The efforts to develop highly active AMPs with shorter sequences are also described.

    Khandelwal, Niraj; Shaw, Joanna; Jain, Mamta K

    2008-04-01

    Parasitic infections of the biliary tract are a common cause of biliary obstruction in endemic areas. This article focuses on primary biliary parasites: Ascaris lumbricoides, Clonorchis sinensis, Opisthorchis viverrini, Opisthorchis felineus, Dicrocoelium dendriticum, Fasciola hepatica, and Fasciola gigantica. Tropical and subtropical countries have the highest incidence and prevalence of these infections. Diagnosis is made primarily through direct microscopic examination of eggs in the stool, duodenal, or bile contents. Radiologic imaging may show intrahepatic ductal dilatation, whereas endoscopic retrograde cholangiopancreatography can be used diagnostically and therapeutically. However, oral treatment is inexpensive and effective for most of these parasites and can prevent untoward consequences. Primary and alternative treatments are available and are reviewed in this article.

    2015-06-01

    To review the pathophysiology and therapeutic modalities availble for Nelson syndrome. We reviewed the current literature including managment for Nelson syndrome. For patients with NS, surgical intervention is often the first-line therapy. With refractory NS or tumors with extrasellar involvement, radiosurgery offers an important alternative or adjuvant option. Pharmacologic interventions have demonstrated limited usefulness, although recent evidence supports the feasibility of a novel somatostatin analog for patients with NS. Modern neuroimaging, improved surgical techniques, and the advent of stereotactic radiotherapy have transformed the management of NS. An up-to-date understanding of the pathophysiology underlying Nelson Syndrome and evidence-based management is imperative. Early detection may allow for more successful therapy in patients with Nelson Syndrome. Improved radiotherapeutic interventions and rapidly evolving pharmacologic therapies offer an opportunity to create targeted, multifocal treatment regiments for patients with Nelson Syndrome.

    2015-12-01

    The central nervous system shows a limited regenerative capacity, and injuries or diseases, such as those in the spinal, brain and retina, are a great problem since current therapies seem to be unable to achieve good results in terms of significant functional recovery. Different promising therapies have been suggested, the aim being to restore at least some of the lost functions. The current review deals with the use of hydrogels in developing advanced devices for central nervous system therapeutic strategies. Several approaches, involving cell-based therapy, delivery of bioactive molecules and nanoparticle-based drug delivery, will be first reviewed. Finally, some examples of injectable hydrogels for the delivery of bioactive molecules in central nervous system will be reported, and the key features as well as the basic principles in designing multifunctional devices will be described. © IMechE 2015.

    Graphene is a multifunctional carbon nanomaterial and could be utilized to develop platform technologies for cancer therapies. Its surface can be covalently and noncovalently functionalized with anticancer drugs and functional groups that target cancer cells and tissue to improve treatment efficacies. Furthermore, its physicochemical properties can be harnessed to facilitate stimulus responsive therapeutics and drug delivery. This review article summarizes the recent literature specifically focused on development of graphene technologies to treat cancer. We will focus on advances at the interface of graphene based drug/gene delivery, photothermal/photodynamic therapy and combinations of these techniques. We also discuss the current understanding in cytocompatibility and biocompatibility issues related to graphene formulations and their implications pertinent to clinical cancer management.

    2006-02-08

    Prementrual dysphoric disorder (PMDD) is considered to be a very severe form of the premenstrual syndrome (PMS) that occurs regularly in the last week of the luteal phase of the cycle and begin to remit after the onset of follicular phase and is absent in the week postmenses. What sets PMDD apart from PMS is its severity and its dominant psychiatric symptoms. PMDD includes depression, anxiety, tension, irritability and moodiness. Moreover, women with PMDD find that it has a very disruptive effect on their everyday lives. Although, many treatments have been used for PMDD over the years, PMDD remains difficult to be cured. Until recently, only few of these treatments were evaluated in carefully designed research studies and even fewer were shown to be effective. Here, we discuss the different therapeutic options for PMDD.

    2018-06-05

    The purpose of this review was to discuss the currently available pharmacologic and non-pharmacologic treatment options for parasomnias. Recent pathophysiological findings about sleep structure in parasomnias helped understanding several drug mechanisms of action. Serotoninergic theory accounts for the effect of serotoninergic drugs. Study about spectral analysis of sleep showed the effect of clonazepam on spectral bands. Cannabinoids proved to be effective in some of parasomnias, as in many other neurological disorders. A series of therapeutic strategies were analyzed and compared. Benzodiazepines, antidepressant drugs, and L-5-hydroxytryptophan may be beneficial in DOA. SSRI and topiramate are effective in SRED. RBD responds to clonazepam, melatonin, and to a lesser extent to dopaminergic and anticholinergic agents. Prazosin and cannabinoids are effective in nightmare disorder. Sleep paralysis may respond to antidepressant agents. Tricyclic antidepressant may be effective in sleep-related hallucinations and exploding head syndrome. Sleep enuresis may be successfully treated with desmopressin, anticholinergic drugs, and imipramine.

  9. Therapeutic strategies in the treatment of periodontitis

    Liljana Bogdanovska

    2012-04-01

    Full Text Available Periodontitis is a chronic inflammatory process which affects the tooth - supporting structures of the teeth. The disease is initiated by subgingival periopathogenic bacteria in susceptible periodontal sites. The host immune response towards periodontal pathogens helps to sustain periodontal disease and eventual alveolar bone loss. Although scaling and root planing is the standard treatment modality for periodontitis, it suffers from several drawbacks such as the inability to reach the base of deep pockets and doesn’t arrest migration of periodontal pathogens from other sites in the oral cavity. In order to overcome the limitations of scaling and root planning, adjunctive chemotherapeutics and host modulatory agents to the treatment are used. These therapeutic agents show substantial beneficial effects when compared to scaling and root planning alone. This review will cover an update on chemotherapeutic and past and future host immune modulatory agents used adjunctively to treat and manage periodontal diseases.

    2014-12-01

    Full Text Available Schizophrenia is a severe psychiatric disorder often associated with cognitive impairment and affective, mainly depressive, symptoms. Antipsychotic medication is the primary intervention for stabilization of acute psychotic episodes and prevention of recurrences and relapses in patients with schizophrenia. Typical antipsychotics, the older class of antipsychotic agents, are currently used much less frequently than newer atypical antipsychotics. Therapeutic drug monitoring (TDM of antipsychotic drugs is the specific method of clinical pharmacology, which involves measurement of drug serum concentrations followed by interpretation and good cooperation with the clinician. TDM is a powerful tool that allows tailor-made treatment for the specific needs of individual patients. It can help in monitoring adherence, dose adjustment, minimizing the risk of toxicity and in cost-effectiveness in the treatment of psychiatric disorders. The review provides complex knowledge indispensable to clinical pharmacologists, pharmacists and clinicians for interpretation of TDM results.

    2010-01-01

    Sickness befallen onto him, man found that plant and animal derivatives invigorated him. Thereafter, he found a therapeutic benefit in using man as a means of self cure and especially, dead man from violent death. The foam of the skull of cadaver was an excellent antiepileptic as well as blood coming out from a freshly decapitated man. By applying on diseased parts of his body, so as to get rid of inflammation or infection, cadaver's hands were used against tumors of all kinds. Dead human skin were processed into belts and used therein for helping delivery of parturition women. The mummy must be blackish, foul smelling and hard. Those who were whitish, odorless and powder-like, were unfit for use. Mummy powder applied to the nose would stop nose bleeding. Ambroise Paré (1510-1590) was an adversary of those practices.

    2007-01-01

    The overall aim of this coordinated research project was to develop in vivo and in vitro laboratory methods to evaluate therapeutic radiopharmaceuticals. Towards this end, the laboratory methods used in this study are described in detail. Two peptides - an 8 amino acid minigastrin analogue and octreotate - were labelled with 177 Lu. Bombesin was labelled with 99 mTc, and its diagnostic utility was proven. For comparison, 99 mTc-TOC was used. The cell lines used in this study were AR42J cells, which overexpress somatostatin receptors found in neuroendocrine cancers, and PC3 cells, which overexpress gastric releasing peptide receptors (GRP-r) found in human prostate and breast cancers. The animal model chosen was athymic mice with implanted dorsal tumours of pathologically confirmed cell cancers. The methodology described for labelling, quality control, and in vitro and in vivo assays can be easily used with other radionuclides and other peptides of interest. (author)

  13. Integrins as Therapeutic Targets: Successes and Cancers

    Directory of Open Access Journals (Sweden)

    Sabine Raab-Westphal

    2017-08-01

    Full Text Available Integrins are transmembrane receptors that are central to the biology of many human pathologies. Classically mediating cell-extracellular matrix and cell-cell interaction, and with an emerging role as local activators of TGFβ, they influence cancer, fibrosis, thrombosis and inflammation. Their ligand binding and some regulatory sites are extracellular and sensitive to pharmacological intervention, as proven by the clinical success of seven drugs targeting them. The six drugs on the market in 2016 generated revenues of some US$3.5 billion, mainly from inhibitors of α4-series integrins. In this review we examine the current developments in integrin therapeutics, especially in cancer, and comment on the health economic implications of these developments.

  14. Is methane a new therapeutic gas?

    Directory of Open Access Journals (Sweden)

    Liu Wenwu

    2012-09-01

    Full Text Available Abstract Background Methane is an attractive fuel. Biologically, methanogens in the colon can use carbon dioxide and hydrogen to produce methane as a by-product. It was previously considered that methane is not utilized by humans. However, in a recent study, results demonstrated that methane could exert anti-inflammatory effects in a dog small intestinal ischemia-reperfusion model. Point of view Actually, the bioactivity of methane has been investigated in gastrointestinal diseases, but the exact mechanism underlying the anti-inflammatory effects is required to be further elucidated. Methane can cross the membrane and is easy to collect due to its abundance in natural gas. Although methane is flammable, saline rich in methane can be prepared for clinical use. These seem to be good news in application of methane as a therapeutic gas. Conclusion Several problems should be resolved before its wide application in clinical practice.

  15. Cyclic peptide therapeutics: past, present and future.

    Zorzi, Alessandro; Deyle, Kaycie; Heinis, Christian

    2017-06-01

    Cyclic peptides combine several favorable properties such as good binding affinity, target selectivity and low toxicity that make them an attractive modality for the development of therapeutics. Over 40 cyclic peptide drugs are currently in clinical use and around one new cyclic peptide drug enters the market every year on average. The vast majority of clinically approved cyclic peptides are derived from natural products, such as antimicrobials or human peptide hormones. New powerful techniques based on rational design and in vitro evolution have enabled the de novo development of cyclic peptide ligands to targets for which nature does not offer solutions. A look at the cyclic peptides currently under clinical evaluation shows that several have been developed using such techniques. This new source for cyclic peptide ligands introduces a freshness to the field, and it is likely that de novo developed cyclic peptides will be in clinical use in the near future.

    Neis, Vivian B; Rosa, Priscila B; Olescowicz, Gislaine; Rodrigues, Ana Lúcia S

    2017-09-01

    Agmatine is a neuromodulator that regulates multiple neurotransmitters and signaling pathways. Several studies have focused on elucidating the mechanisms underlying the neuroprotective effects of this molecule, which seems to be mediated by a reduction in oxidative damage, neuroinflammation, and proapoptotic signaling. Since these events are implicated in acute and chronic excitotoxicity-related disorders (ischemia, epilepsy, traumatic brain injury, spinal cord injury, neurodegenerative, and psychiatric disorders) as well as in nociception, agmatine has been proposed as a therapeutic strategy for the treatment of central nervous system (CNS) disorders. Agmatine also stimulates the expression of trophic factors and adult neurogenesis, contributing to its ability to induce endogenous repair mechanisms. Therefore, considering its wide range of biological effects, this review summarizes the current knowledge about its protective and regenerative properties in the CNS. Copyright © 2017 Elsevier Ltd.

    Historically, therapeutic hypnosis has been met with skepticism within some fields, although acceptance has expanded in recent decades. Development and application of ethical standards and principles has contributed to increased acceptance of hypnosis with children. The Ethics Code of the American Psychological Association (APA, 2002) and the Code of Conduct of the American Society of Clinical Hypnosis (ASCH, 2000) serve as guides to ethical considerations when treating children. From a developmental and practical perspective, children have limited decision-making capacities, therefore special attention should be paid to their rights and welfare. Important ethical considerations relevant to children and hypnosis have emerged, including competence, supervision, informed consent, confidentiality, and boundaries. Considerations are reviewed from a normal and abnormal child development perspective.

    Fetal and neonatal hyperthyroidism may occur in mothers with Graves’ disease. Fetal thyrotoxicosis manifestation is observed with the transition of TSH receptor stimulating antibodies to the fetus from the 17th–20th weeks of pregnancy and with the fetal TSH receptors becoming responsive after 20 weeks. The diagnosis is confirmed by fetal tachycardia, goiter and bone age advancement in pregnancy and maternal treatment is conducted in accordance. The probability of neonatal hyperthyroidism is high in the babies of mothers that have ongoing antithyroid requirement and higher antibody levels in the last months of pregnancy. Clinical manifestation may be delayed by 7–17 days because of the antithyroid drugs taken by the mother. Neonatal hyperthyroidism symptoms can be confused with sepsis and congenital viral infections. Herein, the diagnosis and therapeutic approach are reviewed in cases of fetal neonatal hyperthyroidism. PMID:28439194

    Novel strategies are being researched to discover vaccines to prevent and treat HIV-1. Nonefficacious preventative vaccine approaches include bivalent recombinant gp120 alone, HIV gene insertion into an Adenovirus 5 (Ad5) virus vector and the DNA prime/Ad5 boost vaccine regimen. However, the ALVAC-HIV prime/AIDSVAX® B/E gp120 boost regimen showed 31.2% efficacy at 3.5 years, and is being investigated as clade C constructs with an additional boost. Likewise, although multiple therapeutic vaccines have failed in the past, in a non-placebo controlled trial, a Tat vaccine demonstrated immune cell restoration, reduction of immune activation, and reduced HIV-1 DNA viral load. Monoclonal antibodies for passive immunization or treatment show promise, with VRC01 entering advanced clinical trials. PMID:26985884

    Amyotrophic lateral sclerosis (ALS) is a fatal chronic neurodegenerative disease whose hallmark is proteinaceous, ubiquitinated, cytoplasmic inclusions in motor neurons and surrounding cells. Multiple mechanisms proposed as responsible for ALS pathogenesis include dysfunction of protein degradation, glutamate excitotoxicity, mitochondrial dysfunction, apoptosis, oxidative stress, and inflammation. It is therefore essential to gain a better understanding of the underlying disease etiology and search for neuroprotective agents that might delay disease onset, slow progression, prolong survival, and ultimately reduce the burden of disease. Because riluzole, the only Food and Drug Administration (FDA)-approved treatment, prolongs the ALS patient’s life by only 3 months, new therapeutic agents are urgently needed. In this review, we focus on studies of various small pharmacological compounds targeting the proposed pathogenic mechanisms of ALS and discuss their impact on disease progression. PMID:23864030

    transplantation or spontaneous liver regeneration follows in short order. To buy time, the induction of therapeutic hypothermia (core temperature 32 degrees C-35 degrees C) has been shown to effectively bridge patients to transplant. Similar to the experience in patients with cerebral edema after other neurologic...... insults, hypothermia reduces cerebral edema and intracranial hypertension in patients with acute liver failure by decreasing splanchnic ammonia production, restoring normal regulation of cerebral hemodynamics, and lowering oxidative metabolism within the brain. Hypothermia may also ameliorate the degree...... of liver injury. Hypothermia has not been adequately studied for its safety and theoretically may increase the risk of infection, cardiac dysrhythmias, and bleeding, all complications independently associated with acute liver failure. Therefore, although an ample body of experimental and human data...

    Actinic keratosis (AK) is a common reason for consultation in both Primary Care and Specialised Care. It is the third or fourth most common reason for consultation in dermatology, accounting for up to 5-6% of patients attended. It has also been observed that its prevalence has been increasing in the last 10years, compared to other dermatoses. This is also expected to continue to increase due to longer life expectancy, and by the changes in sun exposure habits since the middle of the last century. The aim of this article is to update the concepts of AK, cancerisation field and to present the currently available therapeutic tools. Copyright © 2017. Publicado por Elsevier España, S.L.U.

    Present studies were aimed to research the possible application of a radiosensitizer, nicotinamide, to increase the therapeutical effect of radioiodine. There were used goitrous and normal rats with growing dose of Iodine 131, with and without simultaneous treatment with nicotinamide. The obtained results show that the nicotinamide treatment importantly increases the thyroid radio destructive effect induced by radioiodine. Under these experimental conditions, nicotinamide induces to a significant increase of thyroid vascularisation, without changes in the proteins ADP-ribosylation activity. These results show, for the first time, the radiosensitizer effect of nicotinamide in front of Iodine 131 and give the possibility of using it in the treatment of hyperthyroid or thyroid difference cancer patients.

    On a total of 105 persons with normal iron stores, iron depletion, and iron deficiency the intestinal absorption from therapeutic iron doses (100 mg Fe and 50 mg Fe as ferrous glycocoll sulphate) of a special galenic form was measured. The measurements were performed by means of a whole-body counter and preparations labelled with radio iron ( 59 Fe). Mean values of absorption rates from 100 mg Fe in healthy males were 5.0% and in healthy females 5.6% whereas in latent iron deficiency and in iron deficiency anemia mean values of 10% and 13% were obtained, respectively. The maximum absorption rate of 20 to 25% is reached already in the late stage of latent iron deficiency. Advancing severeness of iron deficiency is not followed by an increase of iron absorption. Investigations an 21 persons showed no significant difference between absorption rates of the galenic preparations used when administered orally before or after breakfast, respectively. (orig.) [de

    Understanding and exploiting molecular mechanisms in biology is central to chemical biology. In 20 years, chemical biology research has advanced from simple mechanistic studies using isolated biological macromolecules to molecular-level and nanomolecular-level mechanistic studies involving whole organisms. This review documents the best of my personal and collaborative academic research work that has made use of a solid organic chemistry and chemical biology approach toward nanomedicine, in which my focus has been on the design, creation and use of synthetic, self-assembly lipid-based nanoparticle technologies for the functional delivery of active pharmaceutical ingredients to target cells in vivo. This research is now leading to precision therapeutics approaches (PTAs) for the treatment of diseases that may define the future of nanomedicine.

    2016-01-01

    The text " Vaidyavallabha " is an authoritative work on Ayurvedic therapeutics written by Hastiruci , a Jain scholar. It belongs to the time period of 1673-1726 CE. Different physical and mental ailments with their treatments are addressed in the 274 verses spanned over eight chapters in this work. In this text many unique, special and simple medicinal preparations for different diseases are given. Many drugs which were easily available in the local area are given much more importance in the treatment. Added to this, method and uniqueness of naming the diseases in the text stand differently when compared to other texts. Even though the text seems to be small, the contribution to the field of Ayurveda practice is priceless.

  8. Cell-Specific Aptamers as Emerging Therapeutics

    Directory of Open Access Journals (Sweden)

    Cindy Meyer

    2011-01-01

    Full Text Available Aptamers are short nucleic acids that bind to defined targets with high affinity and specificity. The first aptamers have been selected about two decades ago by an in vitro process named SELEX (systematic evolution of ligands by exponential enrichment. Since then, numerous aptamers with specificities for a variety of targets from small molecules to proteins or even whole cells have been selected. Their applications range from biosensing and diagnostics to therapy and target-oriented drug delivery. More recently, selections using complex targets such as live cells have become feasible. This paper summarizes progress in cell-SELEX techniques and highlights recent developments, particularly in the field of medically relevant aptamers with a focus on therapeutic and drug-delivery applications.

    is the necessity to be able to identify, select, expand and manipulate cells outside the body. Recent advances in adult stem cell technologies and basic biology have accelerated therapeutic opportunities aimed at eventual clinical applications. Adult stem cells with the ability to differentiate down multiple...... lineages are an attractive alternative to human embryonic stem cells (hES) in regenerative medicine. In many countries, present legislation surrounding hES cells makes their use problematic, and indeed the origin of hES cells may represent a controversial issue for many communities. However, adult stem...... cells are not subject to these issues. This review will therefore focus on adult stem cells. Based on their extensive differentiation potential and, in some cases, the relative ease of their isolation, adult stem cells are appropriate for clinical development. Recently, several observations suggest...

    Brain is one of the most complex organs in human. The current brain research is mainly based on the animal models and traditional cell culture. However, the inherent species differences between humans and animals as well as the gap between organ level and cell level make it difficult to study human brain development and associated disorders through traditional technologies. Recently, the brain organoids derived from pluripotent stem cells have been reported to recapitulate many key features of human brain in vivo, for example recapitulating the zone of putative outer radial glia cells. Brain organoids offer a new platform for scientists to study brain development, neurological diseases, drug discovery and personalized medicine, regenerative medicine, and so on. Here, we discuss the progress, applications, advantages, limitations, and prospects of brain organoid technology in neurosciences and related therapeutics. © 2017 John Wiley & Sons Ltd.

  11. Harnessing the Helminth Secretome for Therapeutic Immunomodulators

    Directory of Open Access Journals (Sweden)

    Dana Ditgen

    2014-01-01

    Full Text Available Helminths are the largest and most complex pathogens to invade and live within the human body. Since they are not able to outpace the immune system by rapid antigen variation or faster cell division or retreat into protective niches not accessible to immune effector mechanisms, their long-term survival depends on influencing and regulating the immune responses away from the mode of action most damaging to them. Immunologists have focused on the excretory and secretory products that are released by the helminths, since they can change the host environment by modulating the immune system. Here we give a brief overview of the helminth-associated immune response and the currently available helminth secretome data. We introduce some major secretome-derived immunomodulatory molecules and describe their potential mode of action. Finally, the applicability of helminth-derived therapeutic proteins in the treatment of allergic and autoimmune inflammatory disease is discussed.

    With the debut of antibiotic drug therapy, and as a result of its ease of use and general success in treating infection, drugs have become the treatment of choice for most bacterial infections. However, the advent of multiple, very aggressive drug-resistant bacteria, an increasing population which cannot tolerate drugs, and the high cost of drug therapy suggest that a new modality for treating infections is needed. The complex interplay of clonal spread, persistence, transfer of resistance elements and cell-to-cell interaction all contribute to the difficulty in developing drugs to treat new antibiotic-resistant bacterial strains. A dynamic non-drug system, using extant pulsed ultraviolet lightwave technology to kill infection, is being developed to destroy pathogens. This paper theorizes that the shock effect of pulsed xenon's high energy ultraviolet pulses at wavelengths between 250-270nm separates the bacteria's DNA bands, and, subsequently, destroys them. Preliminary laboratory tests have demonstrated the ability of the technology to destroy Staphylococcus aureus, Pseudomonas aeruginosa Escherichia coli, Helicobacter pylori, Acinetobacter baumannii, Klebsiella punemonia, Bacillus subtillis, and Aspergillus fumigates at penetration depths of greater than 3mm in fluids with 100% effectiveness in less than five seconds of exposure to pulsed xenon lightwaves. Micro Invasive Technology, Inc is developing .pulsed xenon therapeutic catheters and endoscopic instruments for internal antimicrobial eradication and topographical devices for prophylactic wound, burn and surgical entrance/exit site sterilization. Pulsed Xenon light sources have a broad optical spectrum (190-1200nm), and can generate light pulses with sufficient energy for combined imaging and therapeutic intervention by multiplexing a fiber optic pathway into the body. In addition, Pulsed Xenon has proven ability to activate photo reactive dyes; share endoscopic lightguides with lasers while, simultaneously

  13. Therapeutic effects of low radiation doses

    1994-01-01

    This editorial explores the scientific basis of radiotherapy with doses of < 1 Gy for various non-malignant conditions, in particular dose-effect relationships, risk-benefit considerations and biological mechanisms. A review of the literature, particularly clinical and experimental reports published more than 50 years ago was conducted to clarify the following problems. 1. The dose-response relationships for the therapeutic effects on three groups of conditions: non-malignant skin disease, arthrosis and other painful degenerative joint disorders and anti-inflammatory radiotherapy; 2. risks after radiotherapy and after the best alternative treatments; 3. the biological mechanisms of the different therapeutic effects. Radiotherapy is very effective in all three groups of disease. Few dose-finding studies have been performed, all demonstrating that the optimal doses are considerable lower than the generally recommended doses. In different conditions, risk-benefit analysis of radiotherapy versus the best alternative treatment yields very different results: whereas radiotherapy for acute postpartum mastitis may not be justified any more, the risk-benefit ratio of radiotherapy of other conditions and particularly so in dermatology and some anti-inflammatory radiotherapy appears to be more favourable than the risk-benefit ratio of the best alternative treatments. Radiotherapy can be very effective treatment for various non-malignant conditions such as eczema, psoriasis, periarthritis humeroscapularis, epicondylitis, knee arthrosis, hydradenitis, parotitis and panaritium and probably be associated with less acute and long-term side effects than similarly effective other treatments. Randomized clinical studies are required to find the optimal dosage which, at present, may be unnecessarily high.

  14. Advancements in therapeutically-targeting orphan GPCRs

    Directory of Open Access Journals (Sweden)

    Jennifer eStockert

    2015-05-01

    Full Text Available G-protein coupled receptors (GPCRs are popular biological targets for drug discovery and development. To date there are more than 140 orphan GPCRs, i.e. receptors whose endogenous ligands are unknown. Traditionally orphan GPCRs have been difficult to study and the development of therapeutic compounds targeting these receptors has been extremely slow although these GPCRs are considered important targets based on their distribution and behavioral phenotype revealed by animals lacking the receptor. Recent advances in several methods used to study orphan receptors, including protein crystallography and homology modeling are likely to be useful in the identification of therapeutics targeting these receptors. In the past 13 years, over a dozen different Class A GPCRs have been crystallized; this trend is exciting, since homology modeling of GPCRs has previously been limited by the availability of solved structures. As the number of solved GPCR structures continues to grow so does the number of templates that can be used to generate increasingly accurate models of phylogenetically-related orphan GPCRs. The availability of solved structures along with the advances in using multiple templates to build models (in combination with molecular dynamics simulations that reveal structural information not provided by crystallographic data and methods for modeling hard-to-predict flexible loop regions have improved the quality of GPCR homology models. This, in turn, has improved the success rates of virtual ligand screens that use homology models to identify potential receptor binding compounds. Experimental testing of the predicted hits and validation using traditional GPCR pharmacological approaches can be used to drive ligand-based efforts to probe orphan receptor biology as well as to define the chemotypes and chemical scaffolds important for binding. As a result of these advances, orphan GPCRs are emerging from relative obscurity as a new class of drug

    2015-01-01

    According to literature, therapeutic hypothermia has been applied for treating conditions that causes an interruption in the delivery of oxygen to the brain, giving the patient better chances of survival with a neurological recovery and without any irreversible damage to the brain. Hypothermia is also used during surgeries and circulatory arrest. In this article, the objective temperature of hypothermia is 32 °C, which is considered mild: 32–35 °C. Three techniques of hypothermia induction were considered: external blood cooling, endovascular cooling with a catheter insertion and water bath. Energy and exergy analyses were performed to determine the clinical effectiveness of these techniques and to evaluate the best test parameters, from which it was possible to calculate the body internal temperature, destroyed exergy and exergy efficiency. Moreover, it was proposed an exergy performance index, which takes into account the ability of a given technique to change the exergy of the body. Results indicate that therapeutic hypothermia takes the subject to a state of lower destroyed exergy and higher body exergy efficiency. The exergy performance index shows that lower rates of cooling lead to a better transformation of the exergy removed from the body into variation of the body exergy. - Highlights: • Thermodynamic study of the human body under mild hypothermia. • Energy and Exergy analysis were applied to the human thermal model. • Calculation of destroyed exergy, exergy efficiency. • Hypothermia led the body to a state of lower destroyed exergy. • EBC achieved higher values of destroyed exergy and exergy efficiency

    The therapeutic management of severe hypertriglyceridaemia represents a clinical challenge. The objectives of this study were 1) to identify the clinical characteristics of patients with severe hypertriglyceridaemia, and 2) to analyse the treatment established by the physicians in each case. A cross-sectional study was carried out using the computerised medical records of all patients>18 years of age with a blood triglyceride level≥1,000mg/dL between 1 January 2011 and 31 December 2016. Clinical and laboratory variables were collected. The behaviour of the physicians in the 6 months after the lipid finding was analysed. A total of 420 patients were included (mean age 49.1±11.4 years, males 78.8%). The median of triglycerides was 1,329mg/dL (interquartile range 1,174-1,658). No secondary causes were found in 34.1% of the patients. The most frequent secondary causes were obesity (38.6%) and diabetes (28.1%). Physical activity was recommended and a nutritionist was referred to in 49.1% and 44.2% of the patients, respectively. Secondary causes were identified and attempts were made to correct them in 40.7% of cases. The most indicated pharmacological treatments were fenofibrate 200mg/day (26.5%) and gemfibrozil 900mg/day (19.3%). Few patients received the indication of omega 3 fatty acids or niacin. This study showed, for the first time in our country, the characteristics of a population with severe hypertriglyceridaemia. The therapeutic measures instituted by the physicians were insufficient. Knowing the characteristics in this particular clinical scenario could improve the current approach of these patients. Copyright © 2018 Sociedad Española de Arteriosclerosis.

    2007-01-01

    The purpose of this study was to evaluate the therapeutic efficacy of the cooking group from the burn survivors' perspective. By incorporating concepts of kitchen skills, energy conservation, and desensitization techniques, the cooking group can assist patients with the functional use of their hands, standing tolerance, return to former vocational activities, and socialization with other patients. A questionnaire was developed based on commonly expressed benefits of cooking group. Areas of interest included decreasing anxiety in the kitchen, distraction from their burns, socializing with other burn survivors, and the physical benefits of participating in the group. The results of this study indicate that participants regard the therapeutic cooking group as a valuable treatment modality that effectively combines functional activities with socialization to decrease burn related anxiety and increase motion in a supportive environment for patients with burns.

    2014-12-16

    CONSPECTUS: Chemical programming of macromolecular structures to instill a set of defined chemical properties designed to behave in a sequential and precise manner is a characteristic vision for creating next generation nanomaterials. In this context, biopolymers such as proteins and nucleic acids provide an attractive platform for the integration of complex chemical design due to their sequence specificity and geometric definition, which allows accurate translation of chemical functionalities to biological activity. Coupled with the advent of amino acid specific modification techniques, "programmable" areas of a protein chain become exclusively available for any synthetic customization. We envision that chemically reprogrammed hybrid proteins will bridge the vital link to overcome the limitations of synthetic and biological materials, providing a unique strategy for tailoring precision therapeutics. In this Account, we present our work toward the chemical design of protein- derived hybrid polymers and their supramolecular responsiveness, while summarizing their impact and the advancement in biomedicine. Proteins, in their native form, represent the central framework of all biological processes and are an unrivaled class of macromolecular drugs with immense specificity. Nonetheless, the route of administration of protein therapeutics is often vastly different from Nature's biosynthesis. Therefore, it is imperative to chemically reprogram these biopolymers to direct their entry and activity toward the designated target. As a consequence of the innate structural regularity of proteins, we show that supramolecular interactions facilitated by stimulus responsive chemistry can be intricately designed as a powerful tool to customize their functions, stability, activity profiles, and transportation capabilities. From another perspective, a protein in its denatured, unfolded form serves as a monodispersed, biodegradable polymer scaffold decorated with functional side

    2003-10-01

    By its definition and its etymology, aesthetic surgery is as much a surgery for the soul as for the body. Aesthetic surgery is a true "armed" therapy that essentially targets the psychology of the patient. This therapeutic "arsenal" preserves and/or restores the health of the patient according to its different aspects as defined by the World Health Organization. The plastic surgeon is always concerned about his patient as a whole, and as a human being, of whom he takes charge. Indeed there lies his specificity: He is as well a surgeon and a physician. We identify and analyze, in this chapter, the particular quality of patient-surgeon relationship on a surgical, psychological and juridical level. It is interesting to note that this collaboration results from a spontaneous convergence. The surgeon, the main interested figure, asserts himself mainly as a physician that is totally involved in a dialogue with his patient. He multiplies the interviews and he sharpens his clinical approach, and his own reactions, with regard to the demand for plastic surgery. The psychiatrist establishes the theoretical and practical aspects of the patient demand. The jurist, far from the barren dissertation of the law, reconsiders the environment of the demand and legitimates the generating wish: he insists on the necessary information but also on assuming responsibility. The therapeutic function of the plastic surgery appears essentially related to the success of a psychic repair solicited by the patient but that is scarcely specified by him as such, and of which he is, most probably, rarely fully aware. The process is to listen and to gather the information that guarantees mutual understanding. Plastic surgery is considered irreplaceable by many of our patients, and indisputable by us. It brings incomparable social and human fertility. It is, however, an ambitious and difficult project that is highly demanding. It is far from the impression of facility reflected by the media.

    GOAL OF TREATMENT: Prevention of diabetic micro and macroangiopathy is the goal of treatment in type 2 diabetes mellitus. A well-controlled glucose level is the key to prevention of microangiopathy; there is no threshold level. Antihypertensive treatment, with the goal of blood pressure below 130/80 mmHg is also beneficial in preventing aggravation of microangiopathy. For macroangiopathy, prevention is based in priority on treatment of other risk factors for cardiovascular disease; the threshold level for drug treatment and the therapeutic objective are those defined for secondary prevention in non-diabetic patients, i.e. blood pressure below 140/80 mmHg and LDL cholesterol under 1.30 g/l. The beneficial effect of lower glucose levels on preventing macrovascular risk was not formally demonstrated by the UKPDS, probably because the difference between the control and the treatment group HbA1c levels was minimal, 0.9 points. REVISITING STRATEGY: It is thus time to revisit the preventive strategy for type 2 diabetes mellitus, i.e. step-by-step increments, as currently proposed for worsening glucose levels. Metformine should be prescribed if the HbA1c is above normal in order to achieve the demonstrated benefit in prevention of microangiopathy and in the hope, motivated by pathophysiology data, of preventing insulin failure. Slow-release insulin at bedtime should be added to the oral hypoglycemiants if fasting glucose exceeds 1.60 or 1.80 g/l, even if the HbA1c remains below 8%. NEW HYPOGLYCEMIANTS: The role of these new agents in this more "aggressive" strategy remains to be defined. Glinides will have to demonstrate their superiority over sulfamides (fewer episodes of hypoglycemia with comparable efficacy) to justify their high cost. Glitazones will have to demonstrate a beneficial effect in second intention combination with metformine on cardiovascular morbidity mortality in type 2 diabetes patients with a metabolic insulin-resistance syndrome and visceral obesity

    This study aims to analyze the variables on which depends therapeutic discharge, in patients with a severe dual diagnosis admitted to a professional therapeutic community where their pathology is treated. 325 patients admitted between June 2000 and June 2009 to the therapeutic community. This is a retrospective, cross-sectional study with no control group, based on the detailed analysis of the information collected in a model of semi-structured clinical interview designed in the therapeutic community. The 29.5% of the individuals included in the sample were therapeutically discharged. Of all the variables introduced in this analysis the most significant ones were gender, age at the beginning of treatment, education level, opiate dependence, polidrug abuse, and the presence of psychotic disorders and borderline personality disorder. In our study, gender determines the type of discharge, being therapeutic discharge more frequent among women. A higher educational also increases a better prognosis with a higher rate of therapeutic discharge among individuals with higher education level. A later age at the beginning of the treatment reduces the likelihood of therapeutic discharge. Likewise, polidrug abuse, diagnosis of psychotic disorders and borderline personality disorder are associated to a lower rate of therapeutic discharge. Recognizing these characteristics will allow the early identification of those patients more at risk of dropping treatment hastily, while trying to prevent it by increasing the therapeutic intensity.

    Full Text Available Cardiac glycosides have been used for congestive heart failure and certain cardiac arrhythmias for more than 200 years. Despite the introduction of a variety of new classes of drugs for the management of heart failure, specifically angiotensin-converting enzyme (ACE inhibitors, b-adrenergic antagonists (bblockers, and the aldosterone antagonist spironolactone, digoxin continues to have an important role in long-term outpatient management. However, a narrow margin exists between therapeutic and toxic doses of digoxin, resulting in a high incidence of digoxin toxicity in clinical practice.A wide variety of placebo-controlled clinical trials have unequivocally shown that treatment with digoxin can improve symptoms, quality of life, and exercise tolerance in patients with mild, moderate, or severe heart failure. The clinical relevance of digoxin therapeutic monitoring is also proved but the SDC (Serum Digoxin Conentrations required for optimal clinical efficacy and acceptable toxicity remains controversial. In the last years, international guidelines recommend 1.2 ng/mL as acceptable high level.In this bibliographic synthesis, we aim to collect pertinent informations from MedLine database about exposure-effect relationship in order to assess the evidence level scientific of new digoxin therapeutic monitoring.

    Therapeutic antibodies (IgG-type) contain several post-translational modifications (PTMs) whereby introducing a large heterogeneity, both structural and functional, into this class of therapeutics. Of these modifications, glycosylation in the fragment crystallizable (Fc) region is the most heterogeneous PTM, which can affect the stability of the molecule and interactions with Fc-receptors in vivo. Hence, the glycoform distribution can affect the mode of action and have implications for bioactivity, safety and efficacy of the drug. Main topics of the manuscript include: What factors influence the (Fc) glycan pattern in therapeutic antibodies and how can these glycans be characterized? How does structure of the Fc-glycan relate to function and what methods are available to characterize those functions? Although heterogeneous in their scope, the different sections are intended to combine current knowledge on structure-function correlations of IgG glycan structures with regard to Fc (effector) functions, as well as basic aspects and methodologies for their assessment.

    Video games have been used in a variety of therapeutic and rehabilitative contexts. However, there are health risks associated with playing video games, including the risk of epileptic seizure. Additionally, video games have been criticised for reasons including their portrayal of women and minorities. For games to be accepted as an ethically valid therapeutic tool, these concerns must be addressed. The authors believe that video games can be used as therapeutic tools when used responsibly

    Simple heating of pyroelectric crystals has been used as the basis for compact sources of X rays, electrons, ions and neutrons. We report on the evaluation of the feasibility of using a portable pyroelectric electron accelerator to deliver a therapeutic dose to tissue. Such a device could be mass produced as a handheld, battery-powered instrument. Experiments were conducted with several crystal sizes in which the crystal was heated inside a vacuum chamber and the emitted electrons were allowed to penetrate a thin beryllium window into the surrounding air. A Faraday cup was used to count the number of electrons that exited the window. The energy of these electrons was determined by measuring the energy spectrum of the X rays that resulted from the electron interactions with the Faraday cup. Based on these measurements, the dose that this source could deliver to tissue was calculated using Monte Carlo calculations. It was found that 10(13) electrons with a peak energy of the order of 100 keV were emitted from the beryllium window and could deliver a dose of 1664 Gy to a 2-cm-diameter, 110-microm-deep region of tissue located 1.5 cm from the window with air between the window and the tissue. This dose level is high enough to consider this technology for medical applications in which shallow energy deposition is beneficial.

    Abstract Pain is a hallmark of almost all bodily ailments and can be modulated by agents, including analgesics and anesthetics that suppress pain signals in the central nervous system. Defects in the modulatory systems, including the endogenous pain‐inhibitory pathways, are a major factor in the initiation and chronicity of pain. Thus, pain modulation is particularly applicable to the practice of medicine. This review summarizes the existing literature on pain modulation. Here, we critically reviewed the literature from PubMed on pain modulation published primarily within the past 5 years in high impact journals. Specifically, we have discussed important anatomical landmarks of pain modulation and outlined the endogenous networks and underlying mechanisms of clinically relevant pain modulatory methods. The Gate Control Theory is briefly presented with discussion on the capacity of pain modulation to cause both hyper‐ and hypoalgesia. An emphasis has been given to highlight key areas in pain research that, because of unanswered questions or therapeutic potential, merit additional scientific scrutiny. The information presented in this paper would be helpful in developing novel therapies, metrics, and interventions for improved patient management. PMID:25962969

  8. Phytotherapy: emerging therapeutic option in urologic disease

    Science.gov (United States)

    2012-01-01

    Phytotherapy belongs to the area of complementary and alternative medicine (CAM) and the definition of phytotherapy is the use of plants or plant extracts for medicinal uses. Interest in phytotherapy is growing in both Asian and western countries for its use in the prevention and management of disease, improvement of general health and anti-aging. And also, there are several studies about the efficacy of phytotherapy in urologic diseases like benign prostatic hyperplasia (BPH), erectile dysfunction (ED), late-onset hypogonadism (LOH) and infertility in males. Phytotherapy for BPH including saw palmetto, pygeum, and nettles, is under vigorous research for the therapeutic effect. No solid evidence showing better effective treatment modality for ED than placebo has been found yet for phytotherapy. Recently, a potent NO donor, L-arginine is under research with promising results. Phytotherapy is used by a number of patients with urological disease, and urologists need to have accurate knowledge about phytotherapy as well as keep a cautious approach. The possible effects and side effects should be defined and related to urologic patients by urologists. PMID:26816707

    2015-01-01

    Hepatocellular carcinoma (HCC) is an increasing health problem, representing the second cause of cancer-related mortality worldwide. The major risk factor for HCC is cirrhosis. In developing countries, viral hepatitis represent the major risk factor, whereas in developed countries, the epidemic of obesity, diabetes and nonalcoholic steatohepatitis contribute to the observed increase in HCC incidence. Cirrhotic patients are recommended to undergo HCC surveillance by abdominal ultrasounds at 6-mo intervals. The current diagnostic algorithms for HCC rely on typical radiological hallmarks in dynamic contrast-enhanced imaging, while the use of α-fetoprotein as an independent tool for HCC surveillance is not recommended by current guidelines due to its low sensitivity and specificity. Early diagnosis is crucial for curative treatments. Surgical resection, radiofrequency ablation and liver transplantation are considered the cornerstones of curative therapy, while for patients with more advanced HCC recommended options include sorafenib and trans-arterial chemo-embolization. A multidisciplinary team, consisting of hepatologists, surgeons, radiologists, oncologists and pathologists, is fundamental for a correct management. In this paper, we review the diagnostic and therapeutic management of HCC, with a focus on the most recent evidences and recommendations from guidelines. PMID:26576088

    Recently, it has been reported that video-assisted thoracoscopic chest drainage is a useful treatment for acute empyema, but its indication has not been clarified. We retrospectively reviewed acute empyema patients by dividing them into 3 groups: operation group (7 patients), drainage group (6 patients), and antibiotic treatment group (9 patients), and then we evaluated the therapeutic strategy by examining the radiological findings, drainage period, and hospital stay. In the antibiotic treatment group, the ratio of pleural effusion on chest radiograph was under 1/4 in all patients. There were 5 patients who showed multilocular findings on chest CT, and all patients underwent an operation. Regarding the drainage period, the operation group showed a significantly shorter period than the drainage group. Concerning the hospital stay, the drainage group showed a significantly longer stay than the other 2 groups. The ratio of pleural effusion on chest radiograph was under 1/4, giving an indication for antibiotic treatment. With multilocular findings on CT, an indication for surgery is needed. Patients requiring drainage, which necessitates a long hospital stay, should be advised to consider surgery. (author)

  11. Polymer therapeutics and the EPR effect.

    Science.gov (United States)

    Maeda, Hiroshi

    History of the EPR (enhanced permeability and retention) effect is discussed, which goes back to the analyses of molecular pathology in bacterial infection and edema (extravasation) formation. The first mediator we found for extravasation was bradykinin. Later on, were found nitric oxide and superoxide, then formation of peroxynitrite, that activates procollagenase. In this inflammatory setting many other vascular mediators are involved that are also common to cancer vasculature. Obviously cancer vasculature is defective architechtally, and this makes macromolecular drugs more permeable through the vascular wall. The importance of this pathophysiological event of EPR effect can be applied to macromolecular drug-delivery, or tumor selective delivery, which takes hours to achieve in the primary as well as metastatic tumors, not to mention of the inflamed tissues. The retention of the EPR means that such drugs will be retained in tumor tissues more than days to weeks. This was demonstrated initially, and most dramatically, using SMANCS, a protein-polymer conjugated-drug dissolved in lipid contrast medium (Lipiodol) by administering intraarterially. For disseminating the EPR concept globally, or in the scientific community, Professor Ruth Duncan played a key role at the early stage, as she worked extensively on polymer- therapeutics, and knew its importance.

    2017-01-01

    SUMMARY The three main oral diseases of humans, that is caries, periodontal diseases and oral candidiasis, are associated with microbiome shifts initiated by changes in the oral environment and/or decreased effectiveness of mucosal immune surveillance. In this review we discuss the role that microbial-based therapies may have in the control of these conditions. Most investigations on the use of microorganisms for management of oral disease have been conducted with probiotic strains with some positive but very discrete clinical outcomes. Other strategies such as whole oral microbiome transplantation or modification of community function by enrichment with health-promoting indigenous oral strains may offer more promise but research in this field is still in its infancy. Any microbial-based therapeutics for oral conditions, however, are likely to be only one component within a holistic preventive strategy that should also aim at modification of the environmental influences responsible for the initiation and perpetuation of microbiome shifts associated with oral dysbiosis.

    2018-06-22

    Progranulin (PGRN) is an acrosomal glycoprotein that is synthesized during spermatogenesis. It is overexpressed in tumors and has anti-inflammatory properties. The protein may be cleaved into granulins which display pro-inflammatory properties. In 2006, mutations in progranulin gene (GRN) that cause haploinsufficiency were found in familial cases of frontotemporal dementia (FTD). Patients with null mutations in GRN display very low-plasma PGRN levels; this analysis is useful for identifying mutation carriers, independent of the clinical presentation, and in those before the appearance of symptoms. Areas covered: Here, we review the current knowledge of PGRN physiological functions and GRN mutations associated with FTD; we also summarize state of the art clinical trials and those compounds able to replace PGRN loss in preclinical models. Expert opinion: PGRN represents a promising therapeutic target for FTD. Cohorts suitable for treatment, ideally at the preclinical stage, where pathogenic mechanisms ongoing in the brain are targeted, are available. However, PGRN may have side effects, such as the risk of tumorigenesis, and the risk/benefit ratio of any intervention cannot be predicted. Furthermore, at present, the situation is complicated by the absence of adequate outcome measures.

    2017-01-01

    Dengue is an important global threat caused by dengue virus (DENV) that records an estimated 390 million infections annually. Despite the availability of CYD-TDV as a commercial vaccine, its long-term efficacy against all four dengue virus serotypes remains unsatisfactory. There is therefore an urgent need for the development of antiviral drugs for the treatment of dengue. Peptide was once a neglected choice of medical treatment but it has lately regained interest from the pharmaceutical industry following pioneering advancements in technology. In this review, the design of peptide drugs, antiviral activities and mechanisms of peptides and peptidomimetics (modified peptides) action against dengue virus are discussed. The development of peptides as inhibitors for viral entry, replication and translation is also described, with a focus on the three main targets, namely, the host cell receptors, viral structural proteins and viral non-structural proteins. The antiviral peptides designed based on these approaches may lead to the discovery of novel anti-DENV therapeutics that can treat dengue patients.

    Clinical research regarding the therapeutic benefits of cannabis ("marijuana") has been almost non-existent in the United States since cannabis was given Schedule I status in the Controlled Substances Act of 1970. In order to discover the benefits and adverse effects perceived by medical cannabis patients, especially with regards to chronic pain, we hand-delivered surveys to one hundred consecutive patients who were returning for yearly re-certification for medical cannabis use in Hawai'i. The response rate was 94%. Mean and median ages were 49.3 and 51 years respectively. Ninety-seven per cent of respondents used cannabis primarily for chronic pain. Average pain improvement on a 0-10 pain scale was 5.0 (from 7.8 to 2.8), which translates to a 64% relative decrease in average pain. Half of all respondents also noted relief from stress/anxiety, and nearly half (45%) reported relief from insomnia. Most patients (71%) reported no adverse effects, while 6% reported a cough or throat irritation and 5% feared arrest even though medical cannabis is legal in Hawai'i. No serious adverse effects were reported. These results suggest that Cannabis is an extremely safe and effective medication for many chronic pain patients. Cannabis appears to alleviate pain, insomnia, and may be helpful in relieving anxiety. Cannabis has shown extreme promise in the treatment of numerous medical problems and deserves to be released from the current Schedule I federal prohibition against research and prescription.

    Cannabis-based medications have been a topic of intense study since the endogenous cannabinoid system was discovered two decades ago. In 2011, for the first time, a cannabis extract was approved for clinical use in Germany. Selective literature review. Cannabis-based medications exert their effects mainly through the activation of cannabinoid receptors (CB1 and CB2). More than 100 controlled clinical trials of cannabinoids or whole-plant preparations for various indications have been conducted since 1975. The findings of these trials have led to the approval of cannabis-based medicines (dronabinol, nabilone, and a cannabis extract [THC:CBD=1:1]) in several countries. In Germany, a cannabis extract was approved in 2011 for the treatment of moderate to severe refractory spasticity in multiple sclerosis. It is commonly used off label for the treatment of anorexia, nausea, and neuropathic pain. Patients can also apply for government permission to buy medicinal cannabis flowers for self-treatment under medical supervision. The most common side effects of cannabinoids are tiredness and dizziness (in more than 10% of patients), psychological effects, and dry mouth. Tolerance to these side effects nearly always develops within a short time. Withdrawal symptoms are hardly ever a problem in the therapeutic setting. There is now clear evidence that cannabinoids are useful for the treatment of various medical conditions.

    2012-09-01

    Full Text Available Abstract Despite the combinations of chemotherapy with monoclonal antibodies have further improved response rates, chronic lymphocytic leukemia (CLL remains an incurable disease with an extremely variable course. This article reviews the ongoing clinical advances in the treatment of CLL in both previously untreated and relapsed disease and focuses on the benefit of different therapeutic strategies, the most effective therapy combinations and the potential activity of novel agents. Novel agents and combination therapies have been investigated by several studies in both the upfront and relapsed setting, particularly for patients with 17p deletion, TP53 mutation and fludarabine-refractory CLL. While these agents and combination therapies have improved initial response rates, ongoing studies are continued to determine and improve the efficacy and safety. Despite advancements in the treatment of CLL have led to high response rates, allogeneic hematopoietic stem cell transplantation (allo-HSCT remains the only curative option and reduced-intensity conditioning (RIC allo-HSCT must be strongly considered whenever feasible. As such, ongoing studies of these agents and other novel approaches in clinical development are needed to expand and improve treatment options for CLL patients.

    Sarcoidosis is a granulomatous disorder of unknown cause characterized by non-caseating granuloma in young adults. Cardiac involvement is rare and range from 2 to 75% depending on diagnostic criteria. Cardiac involvement in sarcoidosis may be asymptomatic or may manifest as rhythm/conduction troubles or congestive heart failure. The diagnosis and treatment of cardiac sarcoidosis may be challenging. However, advances have come in recent years from the use of cardiac MRI and 18 FDG-TEP scanner, as well as from the stratification of the risk of ventricular tachycardia/fibrillation. Due to the rarity of the disease, there is no reliable prospective large study to guide therapeutic strategy for cardiac sarcoidosis. Corticosteroids are probably efficacious, in particular in case of atrio-ventricular block or moderate heart failure. Immunosuppressive drugs have not been largely studied but methotrexate could be helpful. In refractory forms, TNF-α antagonists have been used with success.

    2014-01-01

    Present review paper highlights role of BBB in endothelial transport of various substances into the brain. More specifically, permeability functions of BBB in transendothelial transport of various substances such as metabolic fuels, ethanol, amino acids, proteins, peptides, lipids, vitamins, neurotransmitters, monocarbxylic acids, gases, water, and minerals in the peripheral circulation and into the brain have been widely explained. In addition, roles of various receptors, ATP powered pumps, channels, and transporters in transport of vital molecules in maintenance of homeostasis and normal body functions have been described in detail. Major role of integral membrane proteins, carriers, or transporters in drug transport is highlighted. Both diffusion and carrier mediated transport mechanisms which facilitate molecular trafficking through transcellular route to maintain influx and outflux of important nutrients and metabolic substances are elucidated. Present review paper aims to emphasize role of important transport systems with their recent advancements in CNS protection mainly for providing a rapid clinical aid to patients. This review also suggests requirement of new well-designed therapeutic strategies mainly potential techniques, appropriate drug formulations, and new transport systems for quick, easy, and safe delivery of drugs across blood brain barrier to save the life of tumor and virus infected patients.

    2010-01-01

    Full Text Available Due to the prominent angiogenesis that occurs in malignant glioma, antiangiogenic therapy has been attempted. There have been several molecular targets that are specific to malignant gliomas, as well as more broadly in systemic cancers. In this review, I will focus on some topics related to molecular therapeutic targets for glioma angiogenesis. First, important angiogenic factors that could be considered molecular targets are VEGF, VEGF-induced proteins on endothelial cells, tissue factor, osteopontin, v3 integrin, and thymidine phosphorylase as well as endogenous inhibitors, soluble Flt1, and thrombospondin 1. Second, hypoxic areas are also decreased by metronomic CPT11 treatment as well as temozolomide. Third, glioma-derived endothelial cells that are genetically and functionally distinct from normal endothelial cells should be targeted, for example, with SDF-1 and CXCR7 chemokine. Fourth, endothelial progenitor cells (EPCs likely contribute towards glioma angiogenesis in the brain and could be useful as a drug delivery tool. Finally, blockade of delta-like 4 (Dll4 results in a nonfunctioning vasculature and could be another important target distinct from VEGF.

    Cancerous transformation comprises different events that are both genetic and epigenetic. The ultimate goal for such events is to maintain cell survival and proliferation. This transformation occurs as a consequence of different features such as environmental and genetic factors, as well as some types of infection. Many viral infections are considered to be causative agents of a number of different malignancies. To convert normal cells into cancerous cells, oncogenic viruses must function at the epigenetic level to communicate with their host cells. Oncogenic viruses encode certain epigenetic factors that lead to the immortality and proliferation of infected cells. The epigenetic effectors produced by oncogenic viruses constitute appealing targets to prevent and treat malignant diseases caused by these viruses. In this review, we highlight the importance of epigenetic reprogramming for virus-induced oncogenesis, with special emphasis on viral epigenetic oncoproteins as therapeutic targets. The discovery of molecular components that target epigenetic pathways, especially viral factors, is also discussed. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    To review mycotic aneurysms, their radiological diagnosis and therapeutic alternatives. Five men and a woman between 69 and 84 years old were diagnosed during the last 4 years with mycotic aneurysms. Three were in the aorta, one in the thoracic and two in the abdominal region; one was affecting the left primitive iliac artery, another the left popliteal artery and, in the last case, the medial cerebral artery. Hemo cultures were done on all patients. The surgical specimen was cultivated in 4. CAT was done on 5 patients, angiography on another five and Doppler ultrasound scan on two. Five patients showed positive hemo cultures and in two the surgical specimen culture was positive. The findings of the CAT were decisive in being able to suspect that the lesions were mycotic in nature. Three patients had to undergo emergency, expiring either in surgery or in postoperative care. One case was treated by means of aortic endo prosthesis, and one year later the patient remains asymptomatic. The cerebral aneurysm was embolized with metal coils and the patient remains asymptomatic three years later. The popliteal aneurysm underwent surgical intervention using an established protocol with good results. CAT is decisive in the diagnosis of mycotic aneurysms. Once detected, they must be treated without delay as their natural evolution is one of rapid expansion and rupture. Angiographies help in planning the treatment. Radiological intervention plays an important role in the treatment. (Author) 13 refs

    2012-01-01

    Soft tissue sarcomas are an uncommon and diverse group of more than 50 mesenchymal malignancies. The pathogenesis of many of these is poorly understood, but others have begun to reveal the secrets of their inner workings. With considerable effort over recent years, soft tissue sarcomas have increasingly been classified on the basis of underlying molecular alterations. In turn, this has allowed the development and application of targeted agents in several specific, molecularly defined, sarcoma subtypes. This review will focus the rationale for targeted therapy in sarcoma, with emphasis on the relevance of specific molecular factors and pathways in both translocation-associated sarcomas and in genetically complex tumors. In addition, we will address some of the early successes in sarcoma targeted therapy as well as a few challenges and disappointments in this field. Finally we will discuss several possible opportunities represented by poorly understood, but potentially promising new therapeutic targets, as well as several novel biologic agents currently in preclinical and early phase I/II trials. This will provide the reader with context for understanding the current state this field and a sense of where it may be headed in the coming years. PMID:22498582

  4. Therapeutic Use of Native and Recombinant Enteroviruses

    Directory of Open Access Journals (Sweden)

    Jani Ylä-Pelto

    2016-02-01

    Full Text Available Research on human enteroviruses has resulted in the identification of more than 100 enterovirus types, which use more than 10 protein receptors and/or attachment factors required in cell binding and initiation of the replication cycle. Many of these “viral” receptors are overexpressed in cancer cells. Receptor binding and the ability to replicate in specific target cells define the tropism and pathogenesis of enterovirus types, because cellular infection often results in cytolytic response, i.e., disruption of the cells. Viral tropism and cytolytic properties thus make native enteroviruses prime candidates for oncolytic virotherapy. Copy DNA cloning and modification of enterovirus genomes have resulted in the generation of enterovirus vectors with properties that are useful in therapy or in vaccine trials where foreign antigenic epitopes are expressed from or on the surface of the vector virus. The small genome size and compact particle structure, however, set limits to enterovirus genome modifications. This review focuses on the therapeutic use of native and recombinant enteroviruses and the methods that have been applied to modify enterovirus genomes for therapy.

    Rhenium-186 and rhenium-188 represent two important radioisotopes which are of interest for a variety of therapeutic applications in oncology, nuclear medicine and interventional cardiology. Rhenium-186 is directly produced in a nuclear reactor and the 90 hour half-life allows distribution to distant sites. The relatively low specific activity of rhenium-186 produced in most reactors, however, permits use of phosphonates, but limits use for labelled peptides and antibodies. Rhenium-188 has a much shorter 16.9 hour half-life which makes distribution from direct reactor production difficult. However, rhenium-188 can be obtained carrier-free from a tungsten-188/rhenium-188 generator, which has a long useful shelf-life of several months which is cost-effective, especially for developing regions. In this paper we discuss the issues associated with the production of rhenium-186- and rhenium-188 and the development and use of various radiopharmaceuticals and devices labelled with these radioisotopes for bone pain palliation, endoradiotherapy of tumours by selective catheterization and tumour therapy using radiolabelled peptides and antibodies, radionuclide synovectomy and the new field of vascular radiation therapy.

    Within less than a year after its epidemic started (in December 2013) in Guinea, Ebola virus (EBOV), a member of the filoviridae, has spread over a number of West-African countries (Guinea, Sierra Leone and Liberia) and gained allures that have been unprecedented except by human immunodeficiency virus (HIV). Although EBOV is highly contagious and transmitted by direct contact with body fluids, it could be counteracted by the adequate chemoprophylactic and -therapeutic interventions: vaccines, antibodies, siRNAs (small interfering RNAs), interferons and chemical substances, i.e. neplanocin A derivatives (i.e. 3-deazaneplanocin A), BCX4430, favipiravir (T-705), endoplasmic reticulum (ER) α-glucosidase inhibitors and a variety of compounds that have been found to inhibit EBOV infection blocking viral entry or by a mode of action that still has to be resolved. Much has to be learned from the mechanism of action of the compounds active against VSV (vesicular stomatitis virus), a virus belonging to the rhabdoviridae, that in its mode of replication could be exemplary for the replication of filoviridae.

  7. Neutrophils: potential therapeutic targets in tularemia?

    Directory of Open Access Journals (Sweden)

    Lee-Ann H Allen

    2013-12-01

    Full Text Available The central role of neutrophils in innate immunity and host defense has long been recognized, and the ability of these cells to efficiently engulf and kill invading bacteria has been extensively studied, as has the role of neutrophil apoptosis in resolution of the inflammatory response. In the past few years additional immunoregulatory properties of neutrophils were discovered, and it is now clear that these cells play a much greater role in control of the immune response than was previously appreciated. In this regard, it is noteworthy that Francisella tularensis is one of relatively few pathogens that can successfully parasitize neutrophils as well as macrophages, DC and epithelial cells. Herein we will review the mechanisms used by F. tularensis to evade elimination by neutrophils. We will also reprise effects of this pathogen on neutrophil migration and lifespan as compared with other infectious and inflammatory disease states. In addition, we will discuss the evidence which suggests that neutrophils contribute to disease progression rather than effective defense during tularemia, and consider whether manipulation of neutrophil migration or turnover may be suitable adjunctive therapeutic strategies.

    Human α-lactalbumin made lethal to tumor cells (HAMLET) is the first member in a new family of protein-lipid complexes that kills tumor cells with high selectivity. The protein component of HAMLET is α-lactalbumin, which in its native state acts as a substrate specifier in the lactose synthase complex, thereby defining a function essential for the survival of lactating mammals. In addition, α-lactalbumin acquires tumoricidal activity after partial unfolding and binding to oleic acid. The lipid cofactor serves the dual role as a stabilizer of the altered fold of the protein and a coactivator of specific steps in tumor cell death. HAMLET is broadly tumoricidal, suggesting that the complex identifies conserved death pathways suitable for targeting by novel therapies. Sensitivity to HAMLET is defined by oncogene expression including Ras and c-Myc and by glycolytic enzymes. Cellular targets are located in the cytoplasmic membrane, cytoskeleton, mitochondria, proteasomes, lysosomes and nuclei, and specific signaling pathways are rapidly activated, first by interactions of HAMLET with the cell membrane and subsequently after HAMLET internalization. Therapeutic effects of HAMLET have been demonstrated in human skin papillomas and bladder cancers, and HAMLET limits the progression of human glioblastomas, with no evidence of toxicity for normal brain or bladder tissue. These findings open up new avenues for cancer therapy and the understanding of conserved death responses in tumor cells.

    Thiamine, known as vitamin B(1), plays an essential role in energy metabolism. Benfotiamine (S-benzoylthiamine O-monophoshate) is a synthetic S-acyl derivative of thiamine. Once absorbed, benfotiamine is dephosphorylated by ecto-alkaline phosphatase to lipid-soluble S-benzoylthiamine. Transketolase is an enzyme that directs the precursors of advanced glycation end products (AGEs) to pentose phosphate pathway. Benfotiamine administration increases the levels of intracellular thiamine diphosphate, a cofactor necessary for the activation transketolase, resulting in the reduction of tissue level of AGEs. The elevated level of AGEs has been implicated in the induction and progression of diabetes-associated complications. Chronic hyperglycemia accelerates the reaction between glucose and proteins leading to the formation of AGEs, which form irreversible cross-links with many macromolecules such as collagen. In diabetes, AGEs accumulate in tissues at an accelerated rate. Experimental studies have elucidated that binding of AGEs to their specific receptors (RAGE) activates mainly monocytes and endothelial cells and consequently induces various inflammatory events. Moreover, AGEs exaggerate the status of oxidative stress in diabetes that may additionally contribute to functional changes in vascular tone control observed in diabetes. The anti-AGE property of benfotiamine certainly makes it effective for the treatment of diabetic neuropathy, nephropathy and retinopathy. Interestingly, few recent studies demonstrated additional non-AGE-dependent pharmacological actions of benfotiamine. The present review critically analyzed the multifaceted therapeutic potential of benfotiamine. (c) 2010 Elsevier Ltd. All rights reserved.

    The gastrointestinal tract plays a vital role in nutrient supply, digestion, and absorption, and has a crucial impact on the entire organism. Much attention is being paid to utilize animal models to study the pathogenesis of gastrointestinal diseases in response to intestinal development and health. The piglet has a body size similar to that of the human and is an omnivorous animal with comparable anatomy, nutritional requirements, and digestive and associated inflammatory processes, and displays similarities to the human intestinal microbial ecosystem, which make piglets more appropriate as an animal model for human than other non-primate animals. Therefore, the objective of this review is to summarize key attributes of the piglet model with which to study human intestinal development and intestinal health through probing into the etiology of several gastrointestinal diseases, thus providing a theoretical and hopefully practical, basis for further studies on mammalian nutrition, health, and disease, and therapeutics. Given the comparable nutritional requirements and strikingly similar brain developmental patterns between young piglets and humans, the piglet has been used as an important translational model for studying neurodevelopmental outcomes influenced by pediatric nutrition. Because of similarities in anatomy and physiology between pigs and mankind, more emphasises are put on how to use the piglet model for human organ transplantation research.

    Experimental microdosimetry of high LET therapeutic beams were presented. The cyclotron produced fast neutron beams at IMS, TAMVEC and NRL, a reactor fast neutron at YAYOI, a proctor beam at Harvard and a pion beam at TRIUMF are included. Measurements were performed with a conventional tissue equivalent spherical proportional counter with a logarithmic amplifier which made the recording and analysis quite simple. All the energy deposition spectra were analysed in the conventional manner and anti y F, anti y D as well as anti y D* were calculated. The spectra and their mean lineal energies showed wide variations, depending on the particle type, energy, position in phantom. Fractional contribution of elemental particles ( electron, muon, pion, proton, alpha and so on) to the total dose were analysed. For fast neutron beams, the y spectra stayed almost constant at any depth along the central axis in the phantom. The y spectra of proton beam changed slightly along the depth. On the other side, the y spectra of pion beam change drastically in the phantom between plateau and dose peak region. A novel technique of time-of-flight microdosimetry was employed, which made it possible to separate the fractional contribution of contaminant electrons and muons out of pions. Finally, a map of the radiation quality for all the beams is presented and its significances are discussed. (author)

    Full Text Available Abstract An understanding of how the brain changes in chronic pain or responds to pharmacological or other therapeutic interventions has been significantly changed as a result of developments in neuroimaging of the CNS. These developments have occurred in 3 domains : (1 Anatomical Imaging which has demonstrated changes in brain volume in chronic pain; (2 Functional Imaging (fMRI that has demonstrated an altered state in the brain in chronic pain conditions including back pain, neuropathic pain, and complex regional pain syndromes. In addition the response of the brain to drugs has provided new insights into how these may modify normal and abnormal circuits (phMRI or pharmacological MRI; (3 Chemical Imaging (Magnetic Resonance Spectroscopy or MRS has helped our understanding of measures of chemical changes in chronic pain. Taken together these three domains have already changed the way in which we think of pain – it should now be considered an altered brain state in which there may be altered functional connections or systems and a state that has components of degenerative aspects of the CNS.

    Hypothalamic amenorrhea (HA) is a secondary amenorrhea with no evidence of endocrine/systemic causal factors, mainly related to various stressors affecting neuroendocrine control of the reproductive axis. In clinical practice, HA is mainly associated with metabolic, physical, or psychological stress. Stress is the adaptive response of our body through all its homeostatic systems, to external and/or internal stimuli that activate specific and nonspecific physiological pathways. HA occurs generally after severe stress conditions/situations such as dieting, heavy training, or intense emotional events, all situations that can induce amenorrhea with or without body weight loss and HA is a secondary amenorrhea with a diagnosis of exclusion. In fact, the diagnosis is essentially based on a good anamnestic investigation. It has to be investigated using the clinical history of the patient: occurrence of menarche, menstrual cyclicity, time and modality of amenorrhea, and it has to be exclude any endocrine disease or any metabolic (i.e., diabetes) and systemic disorders. It is necessary to identify any stress situation induced by loss, family or working problems, weight loss or eating disorders, or physical training or agonist activity. Peculiar, though not specific, endocrine investigations might be proposed but no absolute parameter can be proposed since HA is greatly dependent from individual response to stressors and/or the adaptive response to stress. This article tries to give insights into diagnosis and putative therapeutic strategies.

    2003-06-01

    To discuss current therapeutic modalities for cow's milk allergy and its prevention. The sources of data include original clinical studies carried out at Ste. Justine Hospital, as well as a systematic search of the published English and French language scientific literature restricted to human subjects using computerized searches (National Public Library of Medicine, Cochrane Database Systems Review) from 1997 to 2002. Search terms for article retrieval included food allergy, milk allergy, therapy, and prevention. The therapy of food allergies depends upon an accurate diagnosis, which remains a challenge in non--IgE-mediated cases. Dietary exclusion remains the mainstay of therapy, with medications reserved for exceptional patients. Preliminary evidence suggests that pancreatic enzyme supplementation may be of benefit for cases with multiple food allergies and severe eczema. Hydrolysate formula use is currently recommended for dietary allergy prevention in infants at an increased risk when maternal milk is insufficient or unavailable. The use of partially hydrolyzed formulas to prevent allergic disorders, including atopic dermatitis, is supported by clinical studies, but cannot be used in the already sensitized, milk-allergic child. Probiotics show enormous potential in preventing food allergic disorders as well.

  18. TRAIL death receptors and cancer therapeutics

    Tumor necrosis factor-related apoptosis inducing ligand (TRAIL) also known as Apo2L is an apoptotic molecule that belongs to the tumor necrosis factor superfamily of cytokines. It mediates its apoptotic effects via its cognate death receptors including DR4 and DR5. Agonistic monoclonal antibodies have also been developed that selectively activate TRAIL death receptors to mediate apoptosis. Multiple clinically relevant agents also upregulate the expression of TRAIL death receptors, and cooperate with TRAIL as well as DR4 and DR5-specific agonistic antibodies to exhibit tumor cell killing. TRAIL is currently in phase I clinical trials, whereas DR4 and DR5-specific agonistic antibodies have been tested in phase I and II studies. Thus, TRAIL has clearly distinguished itself from the other family members including TNF-alpha and FasL both of which could not make it to the clinic due to their toxic nature. It is therefore, evident that the future of TRAIL-based therapeutic approaches looks brighter

    2013-09-01

    Intellectual disability is common and is associated with significant morbidity. Until the latter half of the 20th century, there were no efficacious treatments. Following initial breakthroughs associated with newborn screening and metabolic corrections, little progress was made until recently. With improved understanding of genetic and cellular mechanisms, novel treatment options are beginning to appear for a number of specific conditions. Fragile X and tuberous sclerosis offer paradigms for the development of targeted therapeutics, but advances in understanding of other disorders such as Down syndrome and Rett syndrome, for example, are also resulting in promising treatment directions. In addition, better understanding of the underlying neurobiology is leading to novel developments in enzyme replacement for storage disorders and adjunctive therapies for metabolic disorders, as well as potentially more generalizable approaches that target dysfunctional cell regulation via RNA and chromatin. Physiologic therapies, including deep brain stimulation and transcranial magnetic stimulation, offer yet another direction to enhance cognitive functioning. Current options and evolving opportunities for the intellectually disabled are reviewed and exemplified. Copyright © 2013 American Neurological Association.

  20. Reciprocity in therapeutic relationships: A conceptual review.

    Reciprocity has generally been understood as a process of giving and taking, within an exchange of emotions or services, and has long been recognized as a central part of human life. However, an understanding of reciprocity in professional helping relationships has seldom received attention, despite movements in mental health care towards more collaborative approaches between service users and professionals. In this review, a systematic search of the published papers was conducted in order to explore how reciprocity is conceptualized and understood as part of the dyadic therapeutic relationship between professionals and service users. Eleven papers met our inclusion criteria and a narrative synthesis was used to synthesize the key concepts of reciprocity. The concepts of: 'dynamic equilibrium', 'shared affect', 'asymmetric alliance', and 'recognition as a fellow human being' were recurrent in understandings of reciprocity in professional contexts. These conceptualizations of reciprocity were also linked to specific behavioural and psychological processes. The findings suggest that reciprocity may be conceptualized and incorporated as a component of mental health care, with recurrent and observable processes which may be harnessed to promote positive outcomes for service users. To this end, we make recommendations for further research to progress and develop reciprocal processes in mental health care. © 2015 Australian College of Mental Health Nurses Inc.

    2007-03-01

    Tourette's syndrome is a neuropsychiatric disorder characterised by both involuntary movements, tics, and psychiatric symptoms, attentional deficit disorder, hyperactivity, obsessive compulsive symptoms..., and can be the cause of major disability. Over the past 30 years, several types of treatment have been proposed for the treatment of tics in Tourette's Syndrome, ranging from psychotherapeutic approaches to neurosurgery. The education of the patient and his entourage is fundamental and must be offered to all patients. Psychotherapy does not directly improve the tics but contributes to a better adjustment of both patient and carers to his disability. The decision to start a course of drug therapy depends largely on the impact of the patient's tics on his personal life. Drug treatment relies on neuromodulators acting on a variety of neural systems and whose efficacy has been rarely demonstrated. The literature shows that the latest generation of dopaminergic antagonists have the highest benefit/risk ratio. Recently, deep brain stimulation, by modulating neuronal activity in structures involved in the pathophysiology of the disease, has become a promising therapeutical approach, producing a marked decrease in the severity of tics over that obtained with other treatments.

  2. Site-Specific PEGylation of Therapeutic Proteins

    Jonathan K. Dozier

    2015-10-01

    Full Text Available The use of proteins as therapeutics has a long history and is becoming ever more common in modern medicine. While the number of protein-based drugs is growing every year, significant problems still remain with their use. Among these problems are rapid degradation and excretion from patients, thus requiring frequent dosing, which in turn increases the chances for an immunological response as well as increasing the cost of therapy. One of the main strategies to alleviate these problems is to link a polyethylene glycol (PEG group to the protein of interest. This process, called PEGylation, has grown dramatically in recent years resulting in several approved drugs. Installing a single PEG chain at a defined site in a protein is challenging. Recently, there is has been considerable research into various methods for the site-specific PEGylation of proteins. This review seeks to summarize that work and provide background and context for how site-specific PEGylation is performed. After introducing the topic of site-specific PEGylation, recent developments using chemical methods are described. That is followed by a more extensive discussion of bioorthogonal reactions and enzymatic labeling.

    This repeated-session design sought to answer questions about the effectiveness of therapeutic touch in reduction of stress for 23 individuals following a natural disaster. In addition, methodological issues related to the average length of time for a therapeutic-touch treatment and a method of documenting the nonverbal interaction between subject and toucher were investigated. Findings indicate that stressed people report themselves to be less stressed following therapeutic touch (p = .05). Time of therapeutic-touch intervention varied significantly between the touchers, with a range of 6.8 to 20 minutes. Qualitative data examining the interaction of toucher and subject raised a number of questions that require further study.

    To evaluate the therapeutic effects of probiotics on neonatal jaundice and the safety. Sixty-eight neonates with jaundice were divided into a control group and a treatment group (n=34) randomly, and treated by blue light phototherapy and that in combination with probiotics. The serum bilirubin levels were detected before and 1, 4, 7 days after treatment. The time when therapy showed effects and jaundice faded, clinical outcomes as well as adverse reactions were recorded. The categorical data were expressed as (±s) and compared by t test. The numerical data were expressed as (case, %) and compared by χ² test. P0.05). The levels significantly decreased 1, 4 and 7 days after treatment (P0.05). The treatment group underwent more significant decreases on the 4th and 7th days than the control group did (P=0.002, 0.001). In the treatment group, the therapy exerted effects on (1.0±0.5) d and jaundice faded on (3.8±1.7) d, which were (2.6±0.6) d and (5.3±2.1) d respectively in the control group (P=0.001, 0.002). The effective rate of the treatment group significantly exceeded that of the control group (P=0.002). There were no obvious adverse reactions in either group. Probiotics lowered the serum bilirubin levels of neonates with jaundice rapidly, safely and significantly, and accelerated jaundice fading as well. This method is worthy of application in clinical practice.

    2015-01-01

    To review the diagnostic and therapeutic challenges associated with treating isolated primary breast tuberculosis through discussion of our series of seven cases. Although breast is an uncommon site of occurrence of tuberculosis and isolated primary breast tuberculosis is an even rarer entity, its importance lies in distinguishing it from more common pathologies like abscesses or malignancy and avoiding unnecessary erroneous surgical intervention. The spectrum and presentation is wide and varied and we present our experience in managing seven such cases. A retrospective analysis of all the cases of histopathologically proven primary breast tuberculosis in the last three years at M.S. Ramaiah Hospital (2012-2014) was done. Analysis was in terms of mode of presentation, clinical features, diagnostic modalities used for evaluation and confirmation of the diagnosis, medical treatment and surgical intervention, if any. Special emphasis was placed on dilemmas in diagnosis and difficulties encountered during treatment. All cases were followed up till cure. Patients most commonly presented with a breast abscess, painful breast lumps and recurrent abscesses. Other foci of tuberculosis were ruled out in all of these patients. Majority were treated exclusively with anti-tubercular therapy (although regimens varied), but those with abscesses underwent incision and drainage. All cases were treated and followed up till cure. The challenges associated with primary breast tuberculosis are multiple, including which anti-tubercular therapy regimen to use, when to surgically intervene (as the breast is a cosmetically important area) and treating atypical mycobacteria. We provide a detailed discussion of the challenges we faced and review of literature.

  6. Hedgehog signaling and therapeutics in pancreatic cancer.

    LENUS (Irish Health Repository)

    Kelleher, Fergal C

    2012-02-01

    OBJECTIVE: To conduct a systematic review of the role that the hedgehog signaling pathway has in pancreatic cancer tumorigenesis. METHOD: PubMed search (2000-2010) and literature based references. RESULTS: Firstly, in 2009 a genetic analysis of pancreatic cancers found that a core set of 12 cellular signaling pathways including hedgehog were genetically altered in 67-100% of cases. Secondly, in vitro and in vivo studies of treatment with cyclopamine (a naturally occurring antagonist of the hedgehog signaling pathway component; Smoothened) has shown that inhibition of hedgehog can abrogate pancreatic cancer metastasis. Thirdly, experimental evidence has demonstrated that sonic hedgehog (Shh) is correlated with desmoplasia in pancreatic cancer. This is important because targeting the Shh pathway potentially may facilitate chemotherapeutic drug delivery as pancreatic cancers tend to have a dense fibrotic stroma that extrinsically compresses the tumor vasculature leading to a hypoperfusing intratumoral circulation. It is probable that patients with locally advanced pancreatic cancer will derive the greatest benefit from treatment with Smoothened antagonists. Fourthly, it has been found that ligand dependent activation by hedgehog occurs in the tumor stromal microenvironment in pancreatic cancer, a paracrine effect on tumorigenesis. Finally, in pancreatic cancer, cells with the CD44+CD24+ESA+ immunophenotype select a population enriched for cancer initiating stem cells. Shh is increased 46-fold in CD44+CD24+ESA+ cells compared with normal pancreatic epithelial cells. Medications that destruct pancreatic cancer initiating stem cells are a potentially novel strategy in cancer treatment. CONCLUSIONS: Aberrant hedgehog signaling occurs in pancreatic cancer tumorigenesis and therapeutics that target the transmembrane receptor Smoothened abrogate hedgehog signaling and may improve the outcomes of patients with pancreatic cancer.

    2014-03-01

    Full Text Available The paper deals with creation of optical deflector for management of laser radiation in physiotherapeutic devices. Design features and operation principles of electro-optical, optical-acoustic and mechanical deflectors, giving the possibility to carry out continuous or discrete scanning of a laser beam are shown. Operation mechanism of the mechanical type deflector on the example of domestic laser therapeutic scanners is described in detail. Application possibility in clinical practice for heating technique of the acupuncture points by volumetric scanning of tissues by the radiation of semiconductor lasers on wave lengths equal to 0,67 and 0,85 μm is investigated. Creation justification of the new type deflector is given. Comparison between stable and labile techniques of radiation is carried out. It is shown that more intensive warming up of a skin surface in acupuncture point projection is observed at volumetric scanning, rather than at planar scanning by laser beams. Temperature increase on a skin surface in projection of acupuncture points is detected at radiation in both the visible spectrum range (0,67 μm and the infrared range (0,85 μm. It gives the possibility to apply this scanning method to thermal photo-activation of the point and to extend an existing arsenal of laser reflexology methods. The optical deflector is offered for medical industry, making it possible to carry out volumetric scanning of a laser beam and to facilitate the medical personnel’s work in laser therapy and reflexology consulting rooms.

    The emerging approach to cancer treatment known as targeted therapies offers hope in improving the treatment of therapy-resistant cancers. Recent understanding of the molecular pathogenesis of cancer has led to the development of targeted novel drugs such as monoclonal antibodies, small molecule inhibitors, mimetics, antisense and small interference RNA-based strategies, among others. These compounds act on specific targets that are believed to contribute to the development and progression of cancers and resistance of tumors to conventional therapies. Delivered individually or combined with chemo- and/or radiotherapy, such novel drugs have produced significant responses in certain types of cancer. Among the most successful novel compounds are those which target tyrosine kinases (imatinib, trastuzumab, sinutinib, cetuximab). However, these compounds can cause severe side-effects as they inhibit pathways such as epidermal growth factor receptor (EGFR) or platelet-derived growth factor receptor, which are also important for normal functions in non-transformed cells. Recently, a number of proteins have been identified which show a remarkable tumor-specific cytotoxic activity. This toxicity is independent of tumor type or specific genetic changes such as p53, pRB or EGFR aberrations. These tumor-specific killer proteins are either derived from common human and animal viruses such as E1A, E4ORF4 and VP3 (apoptin) or of cellular origin, such as TRAIL (tumor necrosis factor-related apoptosis-inducing ligand) and MDA-7 (melanoma differentiation associated-7). This review aims to present a current overview of a selection of these proteins with preferential toxicity among cancer cells and will provide an insight into the possible mechanism of action, tumor specificity and their potential as novel tumor-specific cancer therapeutics.

    Despite availability of international evidence-based guidelines for osteoarthritis (OA) management, agreement on the different treatment modalities is lacking. A symposium of European and US OA experts was held within the framework of the Annual European Congress of Rheumatology to discuss and compare guidelines and recommendations for the treatment of knee OA and to reach a consensus for management, particularly for areas in which there is no clear consensus: non-pharmacological therapy; efficacy and safety of analgesics and non-steroidal anti-inflammatory drugs (NSAIDs); intra-articular (i.a.) hyaluronates (HA); and the role of chondroitin sulfate (CS) and/or glucosamine sulfate (GS). All guidelines reviewed agree that knee OA is a progressive disease of the joint whose management requires non-pharmacological and pharmacological approaches. Discrepancies between guidelines are few and mostly reflect heterogeneity of expert panels involved, geographical differences in the availability of pharmacotherapies, and heterogeneity of the studies included. Panels chosen for guideline development should include experts with real clinical experience in drug use and patient management. Implementation of agreed guidelines can be thwarted by drug availability and reimbursement plans, resulting in optimal OA treatment being jeopardized, HA and symptomatic slow-acting drugs for osteoarthritis (SySADOAs) being clear examples of drugs whose availability and prescription can greatly vary geographically. In addition, primary care providers, often responsible for OA management (at least in early disease), may not adhere to clinical care guidelines, particularly for non-pharmacological OA treatment. Harmonization of the recommendations for knee OA treatment is challenging but feasible, as shown by the step-by-step therapeutic algorithm developed by the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO).

    2010-01-01

    The aim of this review is to identify, critically evaluate, and summarize the laughter literature across a number of fields related to medicine and health care to assess to what extent laughter health-related benefits are currently supported by empirical evidence. A comprehensive laughter literature search was performed. A thorough search of the gray literature was also undertaken. A list of inclusion and exclusion criteria was identified. It was necessary to distinguish between humor and laughter to assess health-related outcomes elicited by laughter only. Thematic analysis was applied to summarize laughter health-related outcomes, relationships, and general robustness. Laughter has shown physiological, psychological, social, spiritual, and quality-of-life benefits. Adverse effects are very limited, and laughter is practically lacking in contraindications. Therapeutic efficacy of laughter is mainly derived from spontaneous laughter (triggered by external stimuli or positive emotions) and self-induced laughter (triggered by oneself at will), both occurring with or without humor. The brain is not able to distinguish between these types; therefore, it is assumed that similar benefits may be achieved with one or the other. Although there is not enough data to demonstrate that laughter is an all-around healing agent, this review concludes that there exists sufficient evidence to suggest that laughter has some positive, quantifiable effects on certain aspects of health. In this era of evidence-based medicine, it would be appropriate for laughter to be used as a complementary/alternative medicine in the prevention and treatment of illnesses, although further well-designed research is warranted.

    Diabetic retinopathy (DR) develops in patients with both type 1 and type 2 diabetes and is the major cause of vision loss and blindness in the working population. The main risk factor of DR is hyperglycemia accompanied by enhanced mitochondrial production of reactive oxygen species and oxidative stress, formation of advanced glycation end products (AGE) and hexosamines, increase in polyol metabolism of glucose. The severity of vascular injury depends on the individual genetic background and is modified by other epigenetic, metabolic and haemodynamic factors, including hypertension, dyslipidemia and oxidative stress. In diabetes, damage to the retina occurs in the vasculature (endothelial cells and pericytes), neurons and glia, pigment epithelial cells and infiltrating immunocompetent cells: monocytes, granulocytes, lymfocytes. These activated cells change the production pattern of a number of mediators such as growth factors, proinflammatory cytokines, vasoactive molecules, coagulation factors and adhesion molecules resulting in increased blood flow, increased capillary permeability, proliferation of extracellular matrix and thickening of basal membranes, altered cell turnover (apoptosis, proliferation, hypertrophy), procoagulant and proaggregant pattern, and finally in angiogenesis and tissue remodelling. Brain, liver, adipose tissue, GUT, skeletal muscle and other tissues could be another source of mediators. Therapeutic approaches used for patients with or at risk for diabetic retinopathy include drug therapy to reduce modifiable risk factors, laser photocoagulation, intravitreous administration of anti-VEGF agents/steroids and intraocular surgery. Screening plays an important role in early detection and intervention to prevent the progression of diabetic retinopathy. Described insights into pathophysiological mechanisms responsible for DR, could help in the development of more targeted approach for prevention and treatment of diabetic retinopathy. anti

    Full Text Available Psychological assessment has long been reported as a key component of clinical psychology. This paper examines the complexities surrounding the clinical significance of therapeutic approach to treatment planning. To achieve this objective, the paper searched and used the PsycINFO and PubMed databases and the reference sections of chapters and journal articles to analysed, 1 a strong basis for the usage of therapeutic approach to psychological assessment in treatment plans, 2 explained the conceptual meaning of clinical significant change in therapeutic assessment, 3 answered some of the questions regarding practicability and the clinical significance of therapeutic approach to treatment plans, particularly during or before treatment, 4 linked therapeutic assessment to change in clients’ clinical impression, functioning and therapeutic needs 5 analysed the empirically documenting clinically significant change in therapeutic assessment. Finally, the study suggested that though therapeutic assessment is not sufficient for the systematic study of psychotherapy outcome and process, it is still consistent with both the layman and professional expectations regarding treatment outcome and also provides a precise method for classifying clients as ‘changed’ or ‘unchanged’ on the basis of clinical significance criteria.

    As the therapeutic options in the management of type 2 diabetes increase, there is an increase confusion among health care professionals, thus leading to the phenomenon of therapeutic inertia. This is the failure to escalate or de-escalate treatment when the clinical need for this is required. It has been studied extensively in various settings, however, it has never been reported in any studies focusing solely on primary care physicians with an interest in diabetes. This group is increasingly becoming the focus of managing complex diabetes care in the community, albeit with the support from specialists. In this retrospective audit, we assessed the prevalence of the phenomenon of therapeutic inertia amongst primary care physicians with an interest in diabetes in UK. We also assessed the predictive abilities of various patient level characteristics on therapeutic inertia amongst this group of clinicians. Out of the 240 patients reported on, therapeutic inertia was judged to have occurred in 53 (22.1%) of patients. The full model containing all the selected variables was not statistically significant, p=0.59. So the model was not able to distinguish between situations in which therapeutic inertia occurred and when it did not occur. None of the patient level characteristics on its own was predictive of therapeutic inertia. Therapeutic inertia was present only in about a fifth of patient patients with diabetes being managed by primary care physicians with an interest in diabetes.

    2001-04-01

    The therapeutic relationship is a concept held by many to be fundamental to the identity of mental health nurses. While the therapeutic relationship was given formal expression in nursing theory in the middle of the last century, its origins can be traced to attendants' interpersonal practices in the asylum era. The dominance of medical understandings of mental distress, and the working-class status of asylum attendants, prevented the development of an account of mental health nursing based on attendants' relationships with asylum inmates. It was left to Peplau and other nursing theorists to describe mental health nursing as a therapeutic relationship in the 1940s and later. Some distinctive features of colonial life in New Zealand suggest that the ideal of the attendant as the embodiment of bourgeoisie values seems particularly unlikely to have been realized in the New Zealand context. However, New Zealand literature from the 20th century shows that the therapeutic relationship, as part of a general development of a therapeutic discourse, came to assume a central place in conceptualizations of mental health nursing. While the therapeutic relationship is not by itself a sufficient basis for professional continuity, it continues to play a fundamental role in mental health nurses' professional identity. The way in which the therapeutic relationship is articulated in the future will determine the meaning of the therapeutic relationship for future generations of mental health nurses.

    Shah, Dhaval K

    2015-10-01

    Increasingly sophisticated protein engineering efforts have been undertaken lately to generate protein therapeutics with desired properties. This has resulted in the discovery of the next generation of protein therapeutics, which include: engineered antibodies, immunoconjugates, bi/multi-specific proteins, antibody mimetic novel scaffolds, and engineered ligands/receptors. These novel protein therapeutics possess unique physicochemical properties and act via a unique mechanism-of-action, which collectively makes their pharmacokinetics (PK) and pharmacodynamics (PD) different than other established biological molecules. Consequently, in order to support the discovery and development of these next generation molecules, it becomes important to understand the determinants controlling their PK/PD. This review discusses the determinants that a PK/PD scientist should consider during the design and development of next generation protein therapeutics. In addition, the role of systems PK/PD models in enabling rational development of the next generation protein therapeutics is emphasized.

    2011-10-01

    Immunogenicity of therapeutic proteins lowers patient well-being and drastically increases therapeutic costs. Preventing immunogenicity is an important issue to consider when developing novel therapeutic proteins and applying them in the clinic. Animal models are increasingly used to study immunogenicity of therapeutic proteins. They are employed as predictive tools to assess different aspects of immunogenicity during drug development and have become vital in studying the mechanisms underlying immunogenicity of therapeutic proteins. However, the use of animal models needs critical evaluation. Because of species differences, predictive value of such models is limited, and mechanistic studies can be restricted. This review addresses the suitability of animal models for immunogenicity prediction and summarizes the insights in immunogenicity that they have given so far.

  4. RNA Interference and its therapeutic applications

    2011-10-01

    Full Text Available RNAi is a potent method, requiring only a few molecules of dsRNA per cell to silence the expression. Long molecules of double stranded RNA (dsRNA trigger the process. The dsRNA comes from virus and transposon activity in natural RNAi process, while it can be injected in the cells in experimental processes. The strand of the dsRNA that is identical in sequence to a region in target mRNA molecule is called the sense strand, and the other strand which is complimentary is termed the antisense strand. An enzyme complex called DICER thought to be similar to RNAase III then recognizes dsRNA, and cuts it into roughly 22- nucleotide long fragments. These fragments termed siRNAs for “small interfering RNAs” remain in double stranded duplexes with very short 3' overhangs. However, only one of the two strands, known as the guide strand or antisense strand binds the argonaute protein of RNA-induced silencing complex (RISC and target the complementary mRNA resulting gene silencing. The other anti-guide strand or passenger strand is degraded as a RISC substrate during the process of RISC activation. This form of RNAi is termed as post transcriptional gene silencing (PTGS; other forms are also thought to operate at the genomic or transcriptional level in some organisms. In mammals dsRNA longer than 30 base pairs induces a nonspecific antiviral response. This so-called interferon response results in a nonspecific arrest in translation and induction of apoptosis. This cascade induces a global non-specific suppression of translation, which in turn triggers apoptosis. Interestingly, dsRNAs less than 30 nt in length do not activate the antiviral response and specifically switched off genes in human cells without initiating the acute phase response. Thus these siRNAs are suitable for gene target validation and therapeutic applications in many species, including humans. [Vet. World 2011; 4(5.000: 225-229

    meet the criteria for robust, generic drug discovery technology and open new horizons for the development of future radiopharmaceuticals. We have shown that aptamers directed against the MUC1 antigen, a tumour marker previously extensively used in tumour imaging and therapy, demonstrated high specificity and uniform penetration in tumour xenografts. The future strategy will be to manipulate the molecular weight of the molecules to achieve an optimum balance between the low immunogenicity and excellent tumour penetration for diagnostic imaging and targeted therapy. In this way, a balance can be achieved between the rapid renal clearance and adequate tumour uptake required for diagnostic imaging and targeted therapy. The current work and future prospects for aptamer therapeutics will be described. (author)

    patients affected by RP. Gene therapies hold promises of treatment for patients affected by some of these diseases for the next decade. In a not too far future, the use of pharmacological drugs increasing a better intracellular oxygen availability, without triggering any harmful production of free radical oxygen species (ROS), while exerting an anti-apoptotic effect within photoreceptor cells, appears to be a therapeutical strategy deserving to be tested in an appropriately designed clinical trial. For the present time, optical and electronical devices as well as night-vision glasses are the only possible tools allowing to improve the quality of life of some patients.

    Purpose Prior research has identified unrealistic optimism as a bias that might impair informed consent among patient-subjects in early phase oncology trials. Optimism, however, is not a unitary construct – it can also be defined as a general disposition, or what is called dispositional optimism. We assessed whether dispositional optimism would be related to high expectations for personal therapeutic benefit reported by patient-subjects in these trials but not to the therapeutic misconception. We also assessed how dispositional optimism related to unrealistic optimism. Methods Patient-subjects completed questionnaires designed to measure expectations for therapeutic benefit, dispositional optimism, unrealistic optimism, and the therapeutic misconception. Results Dispositional optimism was significantly associated with higher expectations for personal therapeutic benefit (Spearman r=0.333, poptimism was weakly associated with unrealistic optimism (Spearman r=0.215, p=0.005). In multivariate analysis, both dispositional optimism (p=0.02) and unrealistic optimism (poptimism (p=.0001), but not dispositional optimism, was independently associated with the therapeutic misconception. Conclusion High expectations for therapeutic benefit among patient-subjects in early phase oncology trials should not be assumed to result from misunderstanding of specific information about the trials. Our data reveal that these expectations are associated with either a dispositionally positive outlook on life or biased expectations about specific aspects of trial participation. Not all manifestations of optimism are the same, and different types of optimism likely have different consequences for informed consent in early phase oncology research. PMID:26882017

    To characterize the clinical indications, procedural safety, and outcome of critically ill children requiring therapeutic plasma exchange. Retrospective observational study based on a prospective registry. Tertiary and quaternary referral 30-bed PICU. Forty-eight critically ill children who received therapeutic plasma exchange during an 8-year period (2007-2014) were included in the study. Therapeutic plasma exchange. A total of 48 patients underwent 244 therapeutic plasma exchange sessions. Of those, therapeutic plasma exchange was performed as sole procedure in 193 (79%), in combination with continuous renal replacement therapy in 40 (16.4%) and additional extracorporeal membrane oxygenation in 11 (4.6%) sessions. The most common admission diagnoses were hematologic disorders (30%), solid organ transplantation (20%), neurologic disorders (20%), and rheumatologic disorders (15%). Complications associated with the procedure occurred in 50 (21.2%) therapeutic plasma exchange sessions. Overall, patient survival from ICU was 82%. Although patients requiring therapeutic plasma exchange alone (n = 31; 64%) had a survival rate of 97%, those with additional continuous renal replacement therapy (n = 13; 27%) and extracorporeal membrane oxygenation (n = 4; 8%) had survival rates of 69% and 50%, respectively. Factors associated with increased mortality were lower Pediatric Index of Mortality 2 score, need for mechanical ventilation, higher number of failed organs, and longer ICU stay. Our results indicate that, in specialized centers, therapeutic plasma exchange can be performed relatively safely in critically ill children, alone or in combination with continuous renal replacement therapy and extracorporeal membrane oxygenation. Outcome in children requiring therapeutic plasma exchange alone is excellent. However, survival decreases with the number of failed organs and the need for continuous renal replacement therapy and extracorporeal membrane oxygenation.

    2002-07-01

    To present the frequency resonance hypothesis, a possible mechanical mechanism by which treatment with non-thermal levels of ultrasound stimulates therapeutic effects. The review encompasses a 4-decade history but focuses on recent reports describing the effects of nonthermal therapeutic levels of ultrasound at the cellular and molecular levels. A search of MEDLINE from 1965 through 2000 using the terms ultrasound and therapeutic ultrasound. The literature provides a number of examples in which exposure of cells to therapeutic ultrasound under nonthermal conditions modified cellular functions. Nonthermal levels of ultrasound are reported to modulate membrane properties, alter cellular proliferation, and produce increases in proteins associated with inflammation and injury repair. Combined, these data suggest that nonthermal effects of therapeutic ultrasound can modify the inflammatory response. The concept of the absorption of ultrasonic energy by enzymatic proteins leading to changes in the enzymes activity is not novel. However, recent reports demonstrating that ultrasound affects enzyme activity and possibly gene regulation provide sufficient data to present a probable molecular mechanism of ultrasound's nonthermal therapeutic action. The frequency resonance hypothesis describes 2 possible biological mechanisms that may alter protein function as a result of the absorption of ultrasonic energy. First, absorption of mechanical energy by a protein may produce a transient conformational shift (modifying the 3-dimensional structure) and alter the protein's functional activity. Second, the resonance or shearing properties of the wave (or both) may dissociate a multimolecular complex, thereby disrupting the complex's function. This review focuses on recent studies that have reported cellular and molecular effects of therapeutic ultrasound and presents a mechanical mechanism that may lead to a better understanding of how the nonthermal effects of ultrasound may be

    Pitt, Hannah

    2014-05-01

    This paper develops the concept of therapeutic place experiences by considering the role of activity. Research of community gardening finds that particular tasks are therapeutic and exhibit the characteristics of flow, but those who lack influence over their community gardening are less likely to benefit from flow as their sense of control is reduced. The notion of emplaced flow is proposed to locate individual experiences amongst socio-spatial factors which limit self-determinacy and therefore affect wellbeing. Emplacing flow prompts critical reflection on who is excluded from therapeutic place experiences, and whether sites offering momentary escape have an enduring impact on wellbeing.

    Nanoparticle-based therapeutics with local delivery and external electromagnetic field modulation holds extraordinary promise for soft-tissue cancers such as breast cancer; however, knowledge of the distribution and fate of nanoparticles in vivo is crucial for clinical translation. Here we demonstrate that multiple diagnostic capabilities can be introduced in photothermal therapeutic nanocomplexes by simultaneously enhancing both near-infrared fluorescence and magnetic resonance imaging (MRI). We track nanocomplexes in vivo, examining the influence of HER2 antibody targeting on nanocomplex distribution over 72 h. This approach provides valuable, detailed information regarding the distribution and fate of complex nanoparticles designed for specific diagnostic and therapeutic functions.

    2016-02-01

    Extracellular matrix is composed of a complex array of molecules that together provide structural and functional support to cells. These properties are mainly mediated by the activity of collagenous and elastic fibers, proteoglycans, and proteins such as fibronectin and laminin. ECM composition is tissue-specific and could include matricellular proteins whose primary role is to modulate cell-matrix interactions. In adults, matricellular proteins are primarily expressed during injury, inflammation and disease. Particularly, they are closely associated with the progression and prognosis of cardiovascular and fibrotic diseases, and cancer. This review aims to provide an overview of the potential use of matricellular proteins in drug delivery including the generation of therapeutic agents based on the properties and structures of these proteins as well as their utility as biomarkers for specific diseases.

    Limited effective strategies exist to alleviate or treat disruptive behaviors in people with Alzheimer's disease. Fifty-one residents of a long-term care facility with Alzheimer's disease were randomly assigned to one of three intervention groups. A multiple time series, blinded, experimental design was used to compare the effectiveness of therapeutic touch, simulated therapeutic touch, and usual care on disruptive behavior. Three forms of disruptive behavior comprised the dependent variables: physical aggression, physical nonaggression, and verbal agitation. Physical nonaggressive behaviors decreased significantly in those residents who received therapeutic touch compared with those who received the simulated version and the usual care. No significant differences in physically aggressive and verbally agitated behaviors were observed across the three study groups. The study provided preliminary evidence for the potential for therapeutic touch in dealing with agitated behaviors by people with dementia. Researchers and practitioners must consider a broad array of strategies to deal with these behaviors.

    Directory of Open Access Journals (Sweden)

    Anthony J. Berdis

    2017-11-01

    Full Text Available Inhibiting DNA synthesis is an important therapeutic strategy that is widely used to treat a number of hyperproliferative diseases including viral infections, autoimmune disorders, and cancer. This chapter describes two major categories of therapeutic agents used to inhibit DNA synthesis. The first category includes purine and pyrmidine nucleoside analogs that directly inhibit DNA polymerase activity. The second category includes DNA damaging agents including cisplatin and chlorambucil that modify the composition and structure of the nucleic acid substrate to indirectly inhibit DNA synthesis. Special emphasis is placed on describing the molecular mechanisms of these inhibitory effects against chromosomal and mitochondrial DNA polymerases. Discussions are also provided on the mechanisms associated with resistance to these therapeutic agents. A primary focus is toward understanding the roles of specialized DNA polymerases that by-pass DNA lesions produced by DNA damaging agents. Finally, a section is provided that describes emerging areas in developing new therapeutic strategies targeting specialized DNA polymerases.

  1. Mild Epicureanism: notes toward the definition of a therapeutic attitude.

    Science.gov (United States)

    Strenger, Carlo

    2008-01-01

    Psychotherapists generally feel uncomfortable addressing patients' beliefs, particularly religious beliefs, because of the desire to respect client subjectivity and to avoid the abuse of therapeutic authority. This paper's first contention is that at some junctures, investigation of the client's belief structure can be an important catalyst for change, as exemplified by an extended case example. This stance assumes that much of the individual and collective damage rigid belief systems inflict derives from their function as a defense against death awareness, as described by terror management theory. The paper develops the concept of a therapeutic meta-attitude towards belief mild Epicureanism, related to the classical Greek philosopher Epicurus (341-270 BC). Mild Epicureanism means to soften attachments to all belief systems, even therapeutic theories, to lower their potential inhibition of personal growth. The paper presents the argument that mild Epicureanism is consistent with most therapeutic approaches, and allows addressing clients' belief without interfering with their right to make up their own minds.

  2. [The place of a new drug in the therapeutic strategy].

    Science.gov (United States)

    Castaigne, A; Goehrs, J M; Ravoire, S

    A therapeutic strategy is a hierarchical set of appropriate measures to provide an answer to a pathological state. A drug is a part of this set (together with the diagnosis, the environment and the other medicinal interventions or not). A new drug's place in a therapeutic strategy can be evaluated according to one or several referential(s) when it (or they) exist, referentials which express the state of knowledge before launch of the new drug. The drug's profile (indication or contraindication, etc.), at the point when the marketing authorization is given, is purely theoretical. One must evaluate the real place of the drug under its real conditions of use (pragmatic trials, observable surveys). A new drugs' place in a therapeutic strategy can only be evaluated in the course of time unless a therapeutic revolution occurs.

  3. Dendrimer Advances for the Central Nervous System Delivery of Therapeutics

    2013-01-01

    The effectiveness of noninvasive treatment for central nervous system (CNS) diseases is generally limited by the poor access of therapeutic agents into the CNS. Most CNS drugs cannot permeate into the brain parenchyma because of the blood-brain barrier (BBB), and overcoming this has become one of the most significant challenges in the development of CNS therapeutics. Rapid advances in nanotechnology have provided promising solutions to this challenge. This review discusses the latest applications of dendrimers in the treatment of CNS diseases with an emphasis on brain tumors. Dendrimer-mediated drug delivery, imaging, and diagnosis are also reviewed. The toxicity, biodistribution, and transport mechanisms in dendrimer-mediated delivery of CNS therapeutic agents bypassing or crossing the BBB are also discussed.

    As unique biopolymers, proteins can be employed for therapeutic delivery. They bear important features such as bioavailability, biocompatibility, and biodegradability with low toxicity serving as a platform for delivery of various small molecule therapeutics, gene therapies, protein biologics and cells. Depending on size and characteristic of the therapeutic, a variety of natural and engineered proteins or peptides have been developed. This, coupled to recent advances in synthetic and chemical biology, has led to the creation of tailor-made protein materials for delivery. This review highlights strategies employing proteins to facilitate the delivery of therapeutic matter, addressing the challenges for small molecule, gene, protein and cell transport.

    2015-06-01

    This study examined the temporal relation between therapeutic alliance and outcome in two treatments for bulimia nervosa (BN). Eighty adults with BN symptoms were randomized to 21 sessions of integrative cognitive-affective therapy (ICAT) or enhanced cognitive-behavioral therapy (CBT-E). Bulimic symptoms (i.e., frequency of binge eating and purging) were assessed at each session and posttreatment. Therapeutic alliance (Working Alliance Inventory) was assessed at Sessions 2, 8, 14, and posttreatment. Repeated-measures analyses using linear mixed models with random intercepts were conducted to determine differences in alliance growth by treatment and patient characteristics. Mixed-effects models examined the relation between alliance and symptom improvement. Overall, patients in both treatments reported strong therapeutic alliances. Regardless of treatment, greater therapeutic alliance between (but not within) subjects predicted greater reductions in bulimic behavior; reductions in bulimic behavior also predicted improved alliance. Patients with higher depression, anxiety, or emotion dysregulation had a stronger therapeutic alliance in CBT-E than ICAT, while those with more intimacy problems had greater improvement in therapeutic alliance in ICAT compared to CBT-E. Therapeutic alliance has a unique impact on outcome, independent of the impact of symptom improvement on alliance. Within- and between-subjects effects revealed that changes in alliance over time did not predict symptom improvement, but rather that individuals who had a stronger alliance overall had better bulimic symptom outcomes. These findings indicate that therapeutic alliance is an important predictor of outcome in the treatment of BN. (c) 2015 APA, all rights reserved).

    Kimura, Kiminori; Kohara, Michinori

    2012-10-01

    Chronic hepatitis C caused by infection with the hepatitis C virus(HCV)is a global health problem. HCV causes persistent infection that can lead to chronic liver diseases such as chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. The therapeutic efficacy of antiviral drugs is not optimal in patients with chronic infection; furthermore, an effective vaccine has not yet been developed. To design an effective HCV vaccine, generation of a convenient animal model of HCV infection is necessary. Recently, we used the Cre/loxP switching system to generate an immunocompetent mouse model of HCV expression, thereby enabling the study of host immune responses against HCV proteins. At present vaccine has not yet been shown to be therapeutically effective against chronic HCV infection. We examined the therapeutic effects of a recombinant vaccinia virus(rVV)encoding HCV protein in a mouse model. we generated rVVs for 3 different HCV proteins and found that one of the recombinant viruses encoding a nonstructural protein(rVV-N25)resolved pathological chronic hepatitis C symptoms in the liver. We propose the possibility that rVV-N25 immunization has the potential for development of an effective therapeutic vaccine for HCV induced chronic hepatitis. The utilization of the therapeutic vaccine can protect progress to chronic hepatitis, and as a consequence, leads to eradication of hepatocellular carcinoma. In this paper, we summarized our current study for HCV therapeutic vaccine and review the vaccine development to date.

  11. The intercultural and interracial therapeutic relationship: challenges and recommendations.

    Qureshi, Adil; Collazos, Francisco

    2011-01-01

    Although research has demonstrated that mental health services function with patients from different cultural backgrounds, a variety of culture- and race-related factors can result in services being of lower quality than that which occurs when the clinician and patient are from the same culture. The provision of culturally competent care requires many institutional and organizational adaptations that lie beyond the control of most mental health professionals. The therapeutic relationship, however, remains a key factor of mental healthcare that can be attended to by individual therapists. The therapeutic relationship plays an important role in almost every therapeutic approach, and has been increasingly recognized as representing a means to the provision of quality intercultural and interracial treatment. At the same time, a host of cultural and racial factors relating to both the patient and clinician can compromise the development of the therapeutic relationship. This paper will explore some of the key issues that complicate therapeutic contact and communication, and will outline means by which to strengthen key components of the therapeutic relationship.

    [Purpose] The intensity of therapeutic physical exercise is complex and sometimes controversial in patients with neural injuries. This review assessed whether therapeutic physical exercise is beneficial according to the intensity of the physical exercise. [Methods] The authors identified clinically or scientifically relevant articles from PubMed that met the inclusion criteria. [Results] Exercise training can improve body strength and lead to the physiological adaptation of skeletal muscles and the nervous system after neural injuries. Furthermore, neurophysiological and neuropathological studies show differences in the beneficial effects of forced therapeutic exercise in patients with severe or mild neural injuries. Forced exercise alters the distribution of muscle fiber types in patients with neural injuries. Based on several animal studies, forced exercise may promote functional recovery following cerebral ischemia via signaling molecules in ischemic brain regions. [Conclusions] This review describes several types of therapeutic forced exercise and the controversy regarding the therapeutic effects in experimental animals versus humans with neural injuries. This review also provides a therapeutic strategy for physical therapists that grades the intensity of forced exercise according to the level of neural injury.

  13. Allogenic banking of dental pulp stem cells for innovative therapeutics.

    Medical research in regenerative medicine and cell-based therapy has brought encouraging perspectives for the use of stem cells in clinical trials. Multiple types of stem cells, from progenitors to pluripotent stem cells, have been investigated. Among these, dental pulp stem cells (DPSCs) are mesenchymal multipotent cells coming from the dental pulp, which is the soft tissue within teeth. They represent an interesting adult stem cell source because they are recovered in large amount in dental pulps with non-invasive techniques compared to other adult stem cell sources. DPSCs can be obtained from discarded teeth, especially wisdom teeth extracted for orthodontic reasons. To shift from promising preclinical results to therapeutic applications to human, DPSCs must be prepared in clinical grade lots and transformed into advanced therapy medicinal products (ATMP). As the production of patient-specific stem cells is costly and time-consuming, allogenic biobanking of clinical grade human leukocyte antigen (HLA)-typed DPSC lines provides efficient innovative therapeutic products. DPSC biobanks represent industrial and therapeutic innovations by using discarded biological tissues (dental pulps) as a source of mesenchymal stem cells to produce and store, in good manufacturing practice (GMP) conditions, DPSC therapeutic batches. In this review, we discuss about the challenges to transfer biological samples from a donor to HLA-typed DPSC therapeutic lots, following regulations, GMP guidelines and ethical principles. We also present some clinical applications, for which there is no efficient therapeutics so far, but that DPSCs-based ATMP could potentially treat.

  14. Cell mediated therapeutics for cancer treatment: Tumor homing cells as therapeutic delivery vehicles

    Science.gov (United States)

    Balivada, Sivasai

    Many cell types were known to have migratory properties towards tumors and different research groups have shown reliable results regarding cells as delivery vehicles of therapeutics for targeted cancer treatment. Present report discusses proof of concept for 1. Cell mediated delivery of Magnetic nanoparticles (MNPs) and targeted Magnetic hyperthermia (MHT) as a cancer treatment by using in vivo mouse cancer models, 2. Cells surface engineering with chimeric proteins for targeted cancer treatment by using in vitro models. 1. Tumor homing cells can carry MNPs specifically to the tumor site and tumor burden will decrease after alternating magnetic field (AMF) exposure. To test this hypothesis, first we loaded Fe/Fe3O4 bi-magnetic NPs into neural progenitor cells (NPCs), which were previously shown to migrate towards melanoma tumors. We observed that NPCs loaded with MNPs travel to subcutaneous melanoma tumors. After alternating magnetic field (AMF) exposure, the targeted delivery of MNPs by the NPCs resulted in a mild decrease in tumor size (Chapter-2). Monocytes/macrophages (Mo/Ma) are known to infiltrate tumor sites, and also have phagocytic activity which can increase their uptake of MNPs. To test Mo/Ma-mediated MHT we transplanted Mo/Ma loaded with MNPs into a mouse model of pancreatic peritoneal carcinomatosis. We observed that MNP-loaded Mo/Ma infiltrated pancreatic tumors and, after AMF treatment, significantly prolonged the lives of mice bearing disseminated intraperitoneal pancreatic tumors (Chapter-3). 2. Targeted cancer treatment could be achieved by engineering tumor homing cell surfaces with tumor proteases cleavable, cancer cell specific recombinant therapeutic proteins. To test this, Urokinase and Calpain (tumor specific proteases) cleavable; prostate cancer cell (CaP) specific (CaP1 targeting peptide); apoptosis inducible (Caspase3 V266ED3)- rCasp3V266ED3 chimeric protein was designed in silico.

    Patterson, Amy S

    2016-10-01

    This article explores the reasons for therapeutic pacifism among people living with HIV (PLHIVs) in urban Zambia. It contributes to a growing ethnography on global health, biosociality, and patient-provider dynamics. Therapeutic citizenship is a biopolitical citizenship that includes claims and ethical projects that emerge from techniques to control and manage bodies. In some contexts, therapeutic citizenship has included activism and claims-making against local, national, and international power brokers. This article investigates therapeutic citizenship in the specific context of impoverished urban Zambian compounds, sites of food insecurity, unemployment, and political exclusion, as well as targets for donor, NGO, and faith-based organisation projects and PLHIV support group proliferation. The article utilises data from participant observations at two Lusaka AIDS clinics, interviews, and focused discussions with support groups of PLHIVs. It argues that PLHIVs continuously negotiate subjectivities related to kinship, clientship, religious belief, and political citizenship in processes that complicate therapeutic citizenship. Rather than fostering participation in PLHIV support groups or challenging 'politics as usual' through activist claims-making to institutions of biopower, these processes lead to therapeutic pacifism.

    Therapeutic protein products (TPPs) are of considerable value in the treatment of a variety of diseases, including cancer, hemophilia, and autoimmune diseases. The success of TPP mainly results from prolonged half-life, increased target specificity and decreased intrinsic toxicity compared with small molecule drugs. However, unwanted immune responses against TPP, such as generation of anti-drug antibody, can impact both drug efficacy and patient safety, which has led to requirements for increased monitoring in regulatory studies and clinical practice, termination of drug development, or even withdrawal of marketed products. We present an overview of current knowledge on immunogenicity of TPP and its impact on efficacy and safety. We also discuss methods for measurement and prediction of immunogenicity and review both product-related and patient-related risk factors that affect its development, and efforts that may be taken to mitigate it. Lastly, we discuss gaps in knowledge and technology and what is needed to fill these. Copyright © 2015 Elsevier Inc. All rights reserved.

    2017-01-01

    Background and aim Therapeutic communication, the fundamental component of nursing, is a complex concept. Furthermore, the poor encounters between nursing student and patient demonstrate the necessity of instruction regarding therapeutic communication. The aim of this study was to define and clarify this important concept for including this subject in the nursing curriculum with more emphasis. Methods A literature search was conducted using keywords such as “nursing student”, “patient” and “therapeutic communication” and Persian-equivalent words in Persian databases (including Magiran and Medlib) and English databases (including PubMed, ScienceDirect, Scopus and ProQuest) without time limitation. After extracting concept definitions and determining characteristic features, therapeutic communication in nursing students was defined. Then, sample cases, antecedents, consequences and empirical referents of concept were determined. Results After assessing 30 articles, therapeutic communication defining attributes were as follows: “an important means in building interpersonal relationships”, “a process of information transmission”, “an important clinical competency”, “a structure with two different sections” and “a significant tool in patient centered care”. Furthermore, theoretical and clinical education and receiving educators’ feedback regarding therapeutic communication were considered as antecedents of the concept. Improving physical and psychological health status of patient as well as professional development of nursing students were identified as consequences of the concept. Conclusion Nursing instructors can use these results in order to teach and evaluate therapeutic communication in nursing students and train qualified nurses. Also, nursing students may apply the results to improve the quality of their interactions with patients, perform their various duties and meet patients’ diverse needs. PMID:28979730

    2013-01-01

    ABSTRACT Objective>: To compare vital signs before and after the therapeutic touch observed in hospitalized newborns in neonatal intensive care unit. Methods: This was a quasi-experimental study performed at a neonatal intensive care unit of a municipal hospital, in the city of São Paulo (SP), Brazil. The sample included 40 newborns submitted to the therapeutic touch after a painful procedure. We evaluated the vital signs, such as heart and respiratory rates, temperature and pain intensity, before and after the therapeutic touch. Results: The majority of newborns were male (n=28; 70%), pre-term (n=19; 52%) and born from vaginal delivery (n=27; 67%). Respiratory distress was the main reason for hospital admission (n=16; 40%). There was a drop in all vital signs after therapeutic touch, particularly in pain score, which had a considerable reduction in the mean values, from 3.37 (SD=1.31) to 0 (SD=0.0). All differences found were statistically significant by the Wilcoxon test (p<0.05). Conclusion: The results showed that therapeutic touch promotes relaxation of the baby, favoring reduction in vital signs and, consequently in the basal metabolism rate. PMID:24488378

    Today, we see the Internet as more than just an information infrastructure, but a socializing place and a safe outlet of inner feelings. Many personalities develop aside from real world life due to its anonymous environment. Virtual world interactions are bringing about new psychological illnesses ranging from netaddiction to technostress, as well as online personality disorders and conflicts in multiple identities that exist in the virtual world. Presently, there are no standard therapy models for the virtual environment. There are very few therapeutic environments, or tools especially made for virtual therapeutic environments. The goal of our research is to provide the therapy model and middleware tools for psychologists to use in virtual therapeutic environments. We propose the Cyber Therapy Model, and Projective Agents, a tool used in the therapeutic environment. To evaluate the effectiveness of the tool, we created a prototype system, called the Virtual Group Counseling System, which is a therapeutic environment that allows the user to participate in group counseling through the eyes of their Projective Agent. Projective Agents inherit the user's personality traits. During the virtual group counseling, the user's Projective Agent interacts and collaborates to recover and increase their psychological growth. The prototype system provides a simulation environment where psychologists can adjust the parameters and customize their own simulation environment. The model and tool is a first attempt toward simulating online personalities that may exist only online, and provide data for observation.

    Heart failure is a leading cause of death and the development of effective and safe therapeutic agents for heart failure has been proven challenging. In this study, taking advantage of larval zebrafish, we developed a zebrafish heart failure model for drug screening and efficacy assessment. Zebrafish at 2 dpf (days postfertilization) were treated with verapamil at a concentration of 200 μM for 30 min, which were determined as optimum conditions for model development. Tested drugs were administered into zebrafish either by direct soaking or circulation microinjection. After treatment, zebrafish were randomly selected and subjected to either visual observation and image acquisition or record videos under a Zebralab Blood Flow System. The therapeutic effects of drugs on zebrafish heart failure were quantified by calculating the efficiency of heart dilatation, venous congestion, cardiac output, and blood flow dynamics. All 8 human heart failure therapeutic drugs (LCZ696, digoxin, irbesartan, metoprolol, qiliqiangxin capsule, enalapril, shenmai injection, and hydrochlorothiazide) showed significant preventive and therapeutic effects on zebrafish heart failure (p failure model developed and validated in this study could be used for in vivo heart failure studies and for rapid screening and efficacy assessment of preventive and therapeutic drugs.

    To assess the effect and importance of the therapeutic class of a drug as a determinant for verbal counseling by community pharmacists. Direct external observations (n = 1431) of pharmacist-customer interactions at the point of delivery of prescription medicines were conducted in 7 community pharmacies in Finland. Trained observers noted whether the pharmacist provided information on directions for use, mode of action, and adverse effects. To examine factors associated with counseling, a multiple logistic regression analysis was constructed, with the dependent variable being counseling of any of the 3 observed topics. In addition to therapeutic class, other independent variables were the pharmacy; pharmacist's age, gender, and degree; and the customer's age, gender, previous use of medicine, and question asking. Provision of counseling differed significantly according to therapeutic classes. Counseling on any of the 3 observed topics was most likely to be provided for customers with antibiotics (80%) and least likely for customers with gynecologic preparations (18%). Differences between therapeutic classes remained statistically significant when the effects of the other variables were controlled for. Other significant predictors for any verbal counseling were the pharmacy, customer's previous use of the medicine, and question asking. Therapeutic class is an important variable that should be included in further studies and considered when comparing studies on patient counseling in community pharmacies.

Subjects (n = 19; 16 women and 3 men; mean age 48.6 years, standard deviation (SD) 6.6) with chronic non-specific neck pain were recruited from two inpatient neck rehabilitation courses. Intensity and volume of therapeutic exercises and physical activity were measured in metabolic equivalents (METs) with an objective measurement device and all-time recall questionnaire. Maximum oxygen uptake was determined in METs (METc) by direct maximal cycle ergometer. Subjects' mean METc was 7.2 METs (SD 1.4) or 25.3 ml/kg/min (SD 4.8). Intensity of all therapeutic exercises was 1.9 METs or 27 %METc (SD 5.1) and volume 7.7 MET-hours/week. Intensity of specific neck and shoulder exercises was 2.0 METs or 28 %METc (SD 5.4) and volume 2.5 MET-hours/week. In addition, subjects were more active in everyday life than in inpatient rehabilitation. The therapeutic exercise dose failed to reach previously reported target values for pain relief. The dose of therapeutic exercises and confounding physical activity should be carefully controlled in pain rehabilitation programmes.

    Full Text Available This article describes a qualitative study of helpful aspects of the therapeutic relationship in Integrative Psychotherapy. Participants of the study were sixteen clients who were in the process of Integrative Psychotherapy for at least a year. Participants were interviewed with the adapted version of the Change Interview (Elliott, 1999, which involves a semi-structured empathic exploration of the client's experience in therapy. The analysis of the clients’ experience of Integrative Psychotherapy revealed six categories of helpful aspects of therapeutic relationship: the therapist’s empathic attunement, the therapist’s acceptance, the match between the client and the therapist, feelings of trust and safety, feeling of connection, and experience of a new relational experience. Based on results of the research, we developed a model of the healing relationship in integrative psychotherapy. This model describes the interrelatedness of these six helpful aspects of the therapeutic relationship. The categories of empathic attunement and acceptance proved to be the most important categories relating to the therapist’s contribution to the healing therapeutic relationship. Clients described that the therapist’s empathic attunement and acceptance influenced the development of safety and trust, feelings of connection and promotion of new relational experiences. The results of this study are discussed in relation to the theories of Integrative Psychotherapy and research regarding the therapeutic relationship in psychotherapy.

    Barry, Stephen E

    2008-09-01

    Certain iron-based particle formulations have useful magnetic properties that, when combined with low toxicity and desirable pharmacokinetics, encourage their development for therapeutic applications. This mini-review begins with background information on magnetic particle use as MRI contrast agents and the influence of material size on pharmacokinetics and tissue penetration. Therapeutic investigations, including (1) the loading of bioactive materials, (2) the use of stationary, high-gradient (HG) magnetic fields to concentrate magnetic particles in tissues or to separate material bound to the particles from the body, and (3) the application of high power alternating magnetic fields (AMF) to generate heat in magnetic particles for hyperthermic therapeutic applications are then surveyed. Attention is directed mainly to cancer treatment, as selective distribution to tumors is well-suited to particulate approaches and has been a focus of most development efforts. While magnetic particles have been explored for several decades, their use in therapeutic products remains minimal; a discussion of future directions and potential ways to better leverage magnetic properties and to integrate their use into therapeutic regimens is discussed.

    Breviscapine injection is a Chinese herbal medicine standardized product extracted from Erigeron breviscapus (Vant.) Hand.-Mazz. It has been widely used for treating cardiovascular and cerebrovascular diseases. However, the therapeutic time window and the action mechanism of breviscapine are still unclear. The present study was designed to investigate the therapeutic time window and underlying therapeutic mechanism of breviscapine injection against cerebral ischemic/reperfusion injury. Sprague-Dawley rats were subjected to middle cerebral artery occlusion for 2h followed by 24h of reperfusion. Experiment part 1 was used to investigate the therapeutic time window of breviscapine. Rats were injected intravenously with 50mg/kg breviscapine at different time-points of reperfusion. After 24h of reperfusion, neurologic score, infarct volume, brain water content and serum level of neuron specific enolase (NSE) were measured in a masked fashion. Part 2 was used to explore the therapeutic mechanism of breviscapine. 4-Hydroxy-2-nonenal (4-HNE), 8-hydroxyl-2'- deoxyguanosine (8-OHdG) and the antioxidant capacity of ischemia cortex were measured by ELISA and ferric-reducing antioxidant power (FRAP) assay, respectively. Immunofluorescence and western blot analysis were used to analyze the expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1). Part 1: breviscapine injection significantly ameliorated neurologic deficit, reduced infarct volume and water content, and suppressed the levels of NSE in a time-dependent manner. Part 2: breviscapine inhibited the increased levels of 4-HNE and 8-OHdG, and enhanced the antioxidant capacity of cortex tissue. Moreover, breviscapine obviously raised the expression of Nrf2 and HO-1 proteins after 24h of reperfusion. The therapeutic time window of breviscapine injection for cerebral ischemia/reperfusion injury seemed to be within 5h after reperfusion. By up-regulating the expression of Nrf2/HO-1 pathway

    1971-01-01

    It is noted that as abortion becomes an accepted medical practice, more nurses will be involved in the treatment and counseling of the therapeutic abortion patient. The authors, psychiatric nurses in a Colorado comprehensive urban mental health center, became involved in the treatment of the therapeutic abortion patient with the passing of the State's liberalized 1967 abortion law. As they became involved with all aspects of therapeutic abortion patients' care, they identified 3 specific roles for the psychiatric nurse: 1) providing direct They treatment, 2) providing liaison service and promoting continuity of care for the patient, and 3) providing consultation service to the staff involved with the patient. As the psychiatric nurses shared their own mixed feelings about abortion with the obstetrical staff, the staff began to feel less guilty and less alone with their feelings. The became more involved with the patients and benefited them more.

  11. Challenges to oligonucleotides-based therapeutics for Duchenne muscular dystrophy

    Directory of Open Access Journals (Sweden)

    Goyenvalle Aurélie

    2011-02-01

    Full Text Available Abstract Antisense oligonucleotides are short nucleic acids designed to bind to specific messenger RNAs in order to modulate splicing patterns or inhibit protein translation. As such, they represent promising therapeutic tools for many disorders and have been actively developed for more than 20 years as a form of molecular medicine. Although significant progress has been made in developing these agents as drugs, they are yet not recognized as effective therapeutics and several hurdles remain to be overcome. Within the last few years, however, the prospect of successful oligonucleotides-based therapies has moved a step closer, in particular for Duchenne muscular dystrophy. Clinical trials have recently been conducted for this myopathy, where exon skipping is being used to achieve therapeutic outcomes. In this review, the recent developments and clinical trials using antisense oligonucleotides for Duchenne muscular dystrophy are discussed, with emphasis on the challenges ahead for this type of therapy, especially with regards to delivery and regulatory issues.

  12. Biosynthesis of therapeutic natural products using synthetic biology.

    Awan, Ali R; Shaw, William M; Ellis, Tom

    2016-10-01

    Natural products are a group of bioactive structurally diverse chemicals produced by microorganisms and plants. These molecules and their derivatives have contributed to over a third of the therapeutic drugs produced in the last century. However, over the last few decades traditional drug discovery pipelines from natural products have become far less productive and far more expensive. One recent development with promise to combat this trend is the application of synthetic biology to therapeutic natural product biosynthesis. Synthetic biology is a young discipline with roots in systems biology, genetic engineering, and metabolic engineering. In this review, we discuss the use of synthetic biology to engineer improved yields of existing therapeutic natural products. We further describe the use of synthetic biology to combine and express natural product biosynthetic genes in unprecedented ways, and how this holds promise for opening up completely new avenues for drug discovery and production.

    Current United States Food and Drug Administration (FDA)-approved lithium salts are plagued with a narrow therapeutic window. Recent attempts to find alternative drugs have identified new chemical entities, but lithium's polypharmacological mechanisms for treating neuropsychiatric disorders are highly debated and are not yet matched. Thus, re-engineering current lithium solid forms in order to optimize performance represents a low cost and low risk approach to the desired therapeutic outcome. In this contribution, we employed a crystal engineering strategy to synthesize the first ionic cocrystals (ICCs) of lithium salts with organic anions. We are unaware of any previous studies that have assessed the biological efficacy of any ICCs, and encouragingly we found that the new speciation did not negatively affect established bioactivities of lithium. We also observed that lithium ICCs exhibit modulated pharmacokinetics compared to lithium carbonate. Indeed, the studies detailed herein represent an important advancement in a crystal engineering approach to a new generation of lithium therapeutics.

    2012-01-01

    Full Text Available Class IIa bacteriocins have been primarily explored as natural food preservatives, but there is much interest in exploring the application of these peptides as therapeutic antimicrobial agents. Bacteriocins of this class possess antimicrobial activity against several important human pathogens. Therefore, the therapeutic development of these bacteriocins will be reviewed. Biological and chemical modifications to both stabilize and increase the potency of bacteriocins are discussed, as well as the optimization of their production and purification. The suitability of bacteriocins as pharmaceuticals is explored through determinations of cytotoxicity, effects on the natural microbiota, and in vivo efficacy in mouse models. Recent results suggest that class IIa bacteriocins show promise as a class of therapeutic agents.

    Japan has made 'innovation in science and technology' as one of its central pillars to ensure high growth in its next stage of economic development and its life sciences market which hosts regenerative medicine was proclaimed to be 'the best market in the world right now.' Although life science therapeutic inventions are patentable subject matter under Japanese patent law, there are nuanced obviousness and enablement challenges under Japanese patent law that can be surmounted in view of some encouraging Japanese court developments in fostering a pro-patent applicant environment in the life sciences therapeutic patent field. Nevertheless, great care must be taken when drafting and prosecuting such patent applications in the world's second most important life sciences therapeutic market.

    Blatt, S J; Behrends, R S

    Based on the assumption that the mutative factors that facilitate growth in psychoanalysis involve the same fundamental mechanisms that lead to psychological growth in normal development, this paper considers the constant oscillation between gratification and deprivation leading to internalization as the central therapeutic mechanism of the psychoanalytic process. Patients experience the analytic process as a series of gratifying involvements and experienced incompatibilities that facilitate internalization, whereby the patient recovers lost or disrupted regulatory, gratifying interactions with the analyst, which are real or fantasied, by appropriating these interactions, transforming them into their own, enduring, self-generated functions and characteristics. Patients internalize not only the analyst's interpretive activity, but also the analyst's sensitivity, compassion and acceptance, and, in addition, their own activity in relation to the analyst such as free association. Both interpretation and the therapeutic relationship can contain elements of gratifying involvement and experienced incompatibility that lead to internalization and therefore both can be mutative factors in the therapeutic process.

  20. Endogenous and Synthetic Cannabinoids as Therapeutics in Retinal Disease

    Directory of Open Access Journals (Sweden)

    Despina Kokona

    2016-01-01

    Full Text Available The functional significance of cannabinoids in ocular physiology and disease has been reported some decades ago. In the early 1970s, subjects who smoked Cannabis sativa developed lower intraocular pressure (IOP. This led to the isolation of phytocannabinoids from this plant and the study of their therapeutic effects in glaucoma. The main treatment of this disease to date involves the administration of drugs mediating either the decrease of aqueous humour synthesis or the increase of its outflow and thus reduces IOP. However, the reduction of IOP is not sufficient to prevent visual field loss. Retinal diseases, such as glaucoma and diabetic retinopathy, have been defined as neurodegenerative diseases and characterized by ischemia-induced excitotoxicity and loss of retinal neurons. Therefore, new therapeutic strategies must be applied in order to target retinal cell death, reduction of visual acuity, and blindness. The aim of the present review is to address the neuroprotective and therapeutic potential of cannabinoids in retinal disease.

    Extensive efforts have been devoted to the construction of functional supramolecular nanosystems for applications in catalysis, energy conversion, sensing and biomedicine. The applications of supramolecular nanosystems such as liposomes, micelles, inorganic nanoparticles, carbon materials for cancer diagnostics and therapeutics have been reviewed by other groups. Here, we will focus on the recent momentous advances in the implementation of typical supramolecular hosts (i.e., cyclodextrins, calixarenes, cucurbiturils and metallo-hosts) and their nanosystems in cancer diagnostics and therapeutics. We discuss the evolutive process of supramolecular nanosystems from the structural control and characterization to their diagnostic and therapeutic function exploitation and even the future potentials for clinical translation.

  2. Current issues of RNAi therapeutics delivery and development.

    Science.gov (United States)

    Haussecker, D

    2014-12-10

    12 years following the discovery of the RNAi mechanism in Man, a number of RNAi therapeutics development candidates have emerged with profiles suggesting that they could become drugs of significant medical importance for diseases like TTR amyloidosis, HBV, solid cancers, and hemophilia. Despite this robust progress, the perception of RNAi therapeutics has been on a roller-coaster ride driven not only by science, but also regulatory trends, the stock markets, and Big Pharma business development decisions [1]. This presentation provides an update on the current state of RNAi therapeutics development with a particular focus on what RNAi delivery can achieve today and key challenges to be overcome to expand therapeutic opportunities. The delivery of RNAi triggers to disease-relevant cell types clearly represents the rate-limiting factor in broadly expanding the applicability of RNAi therapeutics. Today, with at least 3 delivery options (lipid nanoparticles/LNPs, GalNAc-siRNA conjugates, Dynamic PolyConjugates/DPCs) for which profound gene knockdowns have been demonstrated in non-human primates and in the clinic, RNAi therapeutics should in principle be able to address most diseases related to gene expression in the liver. Given the central importance of the liver in systemic physiology, this already represents a significant therapeutic and commercial opportunity rivaling that of e.g. monoclonal antibodies. Beyond the liver, there is a reason to believe that current RNAi therapeutics technologies can address a number of solid tumors (e.g. LNPs), diseases of the eye (e.g. self-delivering RNAi triggers) as well as diseases involving the respiratory epithelium (e.g. aerosolized LNPs), certain phagocytic cells (LNPs), hematopoietic stem cells and their progeny (lentiviral DNA-directed RNAi), vascular endothelial cells (cationic lipoplexes), and certain cell types in the kidney (self-delivering RNAi triggers, DPCs; Table 1). Despite this success, there has been a sense that

    Molecular and histopathological profiling have classified breast cancer into multiple sub-types empowering precision treatment. Although estrogen receptor (ER) and human epidermal growth factor receptor (HER2) are the mainstay therapeutic targets in breast cancer, the androgen receptor (AR) is evolving as a molecular target for cancers that have developed resistance to conventional treatments. The high expression of AR in breast cancer and recent discovery and development of new nonsteroidal drugs targeting the AR provide a strong rationale for exploring it again as a therapeutic target in this disease. Ironically, both nonsteroidal agonists and antagonists for the AR are undergoing clinical trials, making AR a complicated target to understand in breast cancer. This review provides a detailed account of AR’s therapeutic role in breast cancer. PMID:27918430

    Recombinant therapeutic proteins have gained enormous importance for clinical applications. The first recombinant products have been produced in E. coli more than 20 years ago. Although with the advent of antibody-based therapeutics mammalian expression systems have experienced a major boost, microbial expression systems continue to be widely used in industry. Their intrinsic advantages, such as rapid growth, high yields and ease of manipulation, make them the premier choice for expression of non-glycosylated peptides and proteins. Innovative product classes such as antibody fragments or alternative binding molecules will further expand the use of microbial systems. Even more, novel, engineered production hosts and integrated technology platforms hold enormous potential for future applications. This review summarizes current applications and trends for development, production and analytical characterization of recombinant therapeutic proteins in microbial systems.

    2014-01-01

    During the last decade, various functional nanostructured materials with interesting optical, magnetic, mechanical and chemical properties have been extensively applied to biomedical areas including imaging, diagnosis and therapy. In therapeutics, most research has focused on the application of nanoparticles as potential delivery vehicles for drugs and genes, because nanoparticles in the size range of 2–100 nm can interact with biological systems at the molecular level, and allow targeted delivery and passage through biological barriers. Recent investigations have even revealed that several kinds of nanomaterials are intrinsically therapeutic. Not only can they passively interact with cells, but they can also actively mediate molecular processes to regulate cell functions. This can be seen in the treatment of cancer via anti-angiogenic mechanisms as well as the treatment of neurodegenerative diseases by effectively controlling oxidative stress. This review will present recent applications of inorganic nanoparticles as therapeutic agents in the treatment of disease. (topical review)

    In terms of immune regulating functions, analysis of the microbiome has led the development of therapeutic strategies that may be applicable to asthma management. This review summarizes the current literature on the gut and lung microbiota in asthma pathogenesis with a focus on the roles of innate molecules and new microbiome-mediated therapeutics. Recent clinical and basic studies to date have identified several possible therapeutics that can target innate immunity and the microbiota in asthma. Some of these drugs have shown beneficial effects in the treatment of certain asthma phenotypes and for protection against asthma during early life. Current clinical evidence does not support the use of these therapies for effective treatment of asthma. The integration of the data regarding microbiota with technologic advances, such as next generation sequencing and omics offers promise. Combining comprehensive bioinformatics, new molecules and approaches may shape future asthma treatment.

    The field of pharmaceutical and medical nanotechnology has grown rapidly in recent decades and offers much promise for therapeutic advances. This review is intended to serve as a quick summary of the major areas in the therapeutic application of nanotechnology. Nanotechnology for therapeutic application falls into two broad categories of particulate systems and nanoengineered devices. Recent studies appear to focus on the development of multifunctional particles for drug delivery and imaging and the development of nanotechnology-based biosensors for diagnostic applications. Cancer treatment and diagnosis appears to be the principal focus of many of these applications, but nanotechnology is also finding application in tissue engineering and surface engineering of medical implants. Particulate drug delivery systems in general appear to be poised for increased use in the clinic, whereas nanoengineered implants and diagnostic sensors might well be the next major wave in the medical use of nanotechnology.

Multiple actions aimed at preparing teachers to conduct the teaching of therapeutic physical culture are developed from the methodological work. In it offered theoretical, methodological and experiential tools for therapeutic exercises generate a developer student learning. Nevertheless, there are still limitations that reveal the need to give continuity to these intentions. One is the traditional approach of the exercises for therapeutic purposes. If we consider that today's society demands the formation of a subject becomes heir and transmitter of a culture of physical activity that achieves deal with their conditions, increasing growing life expectancy, then more than rehabilitation the physical must achieve a comprehensive educational impact.

    The development of solid phase peptide synthesis has released tremendous opportunities for using synthetic peptides in medicinal applications. In the last decades, peptide therapeutics became an emerging market in pharmaceutical industry. The need for synthetic strategies in order to improve peptidic properties, such as longer half-life, higher bioavailability, increased potency and efficiency is accordingly rising. In this mini-review, we present a toolbox of modifications in peptide chemistry for overcoming the main drawbacks during the transition from natural peptides to peptide therapeutics. Modifications at the level of the peptide backbone, amino acid side chains and higher orders of structures are described. Furthermore, we are discussing the future of peptide therapeutics development and their impact on the pharmaceutical market. Copyright © 2018 Elsevier Ltd. All rights reserved.

    1985-01-01

    Methods for the measurement of therapeutic drugs have covered every aspect of analysis from extraction to derivatization. In general, published methods were modified to shorten drug extractions and overall analysis time. The use of different standards, as well as the frequent omission of internal standards, often produced large and clinically unacceptable analytical variations. As a result, physicians would adjust drug dosages according to the physiological response to a standard dose. The introduction of radioimmunoassay techniques for the quantitation of therapeutic drugs have made a significant impact on the clinical chemistry laboratory. The similarities of the various assay methods and the technologists' familiarity with the assay protocols have produced clinically relevant results. Clinical laboratories are now able to frequently analyze a large number of samples with acceptable accuracy and precision. The esoteric test once performed infrequently is today a routine analytical assay often performed STAT. Therapeutic drug monitoring has become a major activity in many clinical laboratories

    Since Wil Gesler's earliest articulation (Gesler, 1992; Gesler, 1996) key thinkers in the field of therapeutic landscapes have sought to emphasise the embodied, contextual and wholly relational nature of the relationship that exists between people and place. However, the extant research has tended to focus on the relational healing experience as this occurs 'in the moment' and with reference to a specific location or site of healing, with less attention being paid to what happens to people when they return to their ordinary or everyday places. In this paper, we reflect on findings from visual ethnographic work (including photography and film) that explored the therapeutic landscape experiences of people with intellectual disabilities engaged in care farming interventions for health and wellbeing. The study also recruited farm staff and family members or carers to take part, and comprised 20 participants in total. Having identified a gap in our understanding, consideration is given to wider impact that engaging in these sorts of activities had on the everyday lives of the participants in this study. We argue that this study has identified two types of therapeutic journey that broadly fit the experiences of study participants. The first type of journey denotes landscape experiences that are transformative. Here the therapeutic power of the care farm landscape resides in the ability of activities conducted on care farms to influence other aspects of participants' lives in ways that promote wellbeing. By contrast, there is another type of journey where the therapeutic power of the care farm resides in its ability to ameliorate challenging or harmful life situations, thus offering people a temporary site of respite or refuge. We conclude that these findings denote an important development for this sub-field of health geography, not only because they draw attention to the transformative power of the therapeutic encounter, but also the broader socio-spatial environments

    Ghrelin is a novel growth hormone-releasing peptide with potential endogenous anti-inflammatory activities ameliorating some pathologic inflammatory conditions. Crohn's disease is a chronic debilitating disease characterized by severe T helper cell (Th)1-driven inflammation of the colon. The aim of this study was to investigate the therapeutic effect of ghrelin in a murine model of colitis. We examined the anti-inflammatory action of ghrelin in the colitis induced by intracolonic administration of trinitrobenzene sulfonic acid. Diverse clinical signs of the disease were evaluated, including weight loss, diarrhea, colitis, and histopathology. We also investigated the mechanisms involved in the potential therapeutic effect of ghrelin, such as inflammatory cytokines and chemokines, Th1-type response, and regulatory factors. Ghrelin ameliorated significantly the clinical and histopathologic severity of the trinitrobenzene sulfonic acid-induced colitis; abrogating body weight loss, diarrhea, and inflammation; and increasing survival. The therapeutic effect was associated with down-regulation of both inflammatory and Th1-driven autoimmune response through the regulation of a wide spectrum of inflammatory mediators. In addition, a partial involvement of interluekin-10/transforming growth factor-beta1-secreting regulatory T cells in this therapeutic effect was demonstrated. Importantly, the ghrelin treatment was therapeutically effective in established colitis and avoided the recurrence of the disease. Our data demonstrate novel anti-inflammatory actions for ghrelin in the gastrointestinal tract, ie, the capacity to deactivate the intestinal inflammatory response and to restore mucosal immune tolerance at multiple levels. Consequently, ghrelin administration represents a novel possible therapeutic approach for the treatment of Crohn's disease and other Th1-mediated inflammatory diseases, such as rheumatoid arthritis and multiple sclerosis.

  14. "Therapeutic" bed rest in pregnancy: unethical and unsupported by data.

    2013-06-01

    "Therapeutic" bed rest continues to be used widely, despite evidence of no benefit and known harms. In this commentary, we summarize the Cochrane reviews of bed rest and propose an ethical argument for discontinuing this practice. Cochrane systematic reviews do not support "therapeutic" bed rest for threatened abortion, hypertension, preeclampsia, preterm birth, multiple gestations, or impaired fetal growth. This assessment has been echoed in other comprehensive reviews. Prescribing bed rest is inconsistent with the ethical principles of autonomy, beneficence, and justice. Hence, if bed rest is to be used, it should be only within a formal clinical trial.

    For modern medicine central venous catheters play an important role for diagnostic and therapeutic options. Catheter implantation, complication detection and therapy of catheter complications are an increasing demand for the radiologist. The review article provides an overview of different catheter types, their indications, advantages and disadvantages. Catheter malpositions are usually detectable in conventional X-ray. Most malpositions are correctable using interventional-radiological techniques. In addition therapeutical options for thrombotic complications (venous thrombosis, catheter occlusion, fibrin sheath) are discussed. In case of an infectious catheter complication, usually a catheter extraction and re-implantation is necessary

    The present study aimed to examine the therapeutic effects of Islamic intercessory prayer on warts. Forty-five participants who are mostly Muslims and infected with warts were randomized into three groups: Group-1 (uncertain, with intercessory prayer), Group-2 (uncertain, no intercessory prayer), and control group (informed, no intervention). Stress symptoms were also measured before and after prayer sessions for these three groups. The results revealed that there were no significant differences between the groups in terms of healing. Although participants believed in the therapeutic effects of prayer, when participants did not trust the intercessor, prayer had no effect on warts.

    Full Text Available Tumor consists of heterogeneous cancer cells including cancer stem cells (CSCs that can terminally differentiate into tumor bulk. Normal stem cells in normal organs regulate self-renewal within a stem cell niche. Likewise, accumulating evidence has also suggested that CSCs are maintained extrinsically within the tumor microenvironment, which includes both cellular and physical factors. Here, we review the significance of stromal cells, immune cells, extracellular matrix, tumor stiffness, and hypoxia in regulation of CSC plasticity and therapeutic resistance. With a better understanding of how CSC interacts with its niche, we are able to identify potential therapeutic targets for the development of more effective treatments against cancer.

    Graves' disease is the most common cause of hyperthyroidism. Clinical features include thyroid enlargement, eye signs, tachycardia, heat intolerance, emotional lability, weight loss, and hyperkinesis. Three modes of therapy are available. The preferences of the patient and physician are usually prime considerations in devising the therapeutic plan. Radioactive iodine is the most frequently used and safest method of treatment for adults. Antithyroid drugs are preferred for children and pregnant women. Surgery is usually reserved for patients in whom the other forms of treatment are not acceptable. Considerable patient education during the decision-making process enhances the success of the therapeutic plan.

    2017-06-01

    Significance: More than 2 million eye injuries and infections occur each year in the United States that leave civilians and military members with reduced or complete vision loss due to the lack of effective therapeutics. Severe ocular injuries and infections occur in varied settings including the home, workplace, and battlefields. In this review, we discuss the potential of developing antimicrobial peptides (AMPs) as therapeutics for the treatment of corneal wounds and infections for which the current treatment options are inadequate. Recent Advances: Standard-of-care employs the use of fluorescein dye for the diagnosis of ocular defects and is followed by the use of antibiotics and/or steroids to treat the infection and reduce inflammation. Recent advances for treating corneal wounds include the development of amniotic membrane therapies, wound chambers, and drug-loaded hydrogels. In this review, we will discuss an innovative approach using AMPs with the dual effect of promoting corneal wound healing and clearing infections. Critical Issues: An important aspect of treating ocular injuries is that treatments need to be effective and administered expeditiously. This is especially important for injuries that occur during combat and in individuals who demonstrate delayed wound healing. To overcome gaps in current treatment modalities, bioactive peptides based on naturally occurring cationic antimicrobial proteins are being investigated as new therapeutics. Future Directions: The development of new therapeutics that can treat ocular infections and promote corneal wound healing, including the healing of persistent corneal epithelial defects, would be of great clinical benefit.

    2013-10-01

    Full Text Available INTRODUCTION: Temporomandibular disorder (TMD is a multifactorial disease. For this reason, it is difficult to obtain an accurate and correct diagnosis. In this context, conservative treatments, including therapeutic exercises classified as stretching, relaxation, coordination, strengthening and endurance, are oftentimes prescribed. OBJECTIVE: Thus, the aim of the present article was to conduct a literature review concerning the types of exercises available and the efficacy for the treatment of muscular TMD. METHODS: The review included researches carried out between 2000 and 2010, indexed on Web of Science, PubMed, LILACS and BBO. Moreover, the following keywords were used: Exercise, physical therapy, facial pain, myofascial pain syndrome, and temporomandibular joint dysfunction syndrome. Studies that did not consider the subject "TMD and exercises", used post-surgery exercises and did not use validated criteria for the diagnosis of TMD (RDC/TMD were not included. RESULTS: The results comprised seven articles which proved therapeutic exercises to be effective for the treatment of muscular TMD. However, these studies are seen as limited, since therapeutic exercises were not applied alone, but in association with other conservative procedures. In addition, they present some drawbacks such as: Small samples, lack of control group and no detailed exercise description which should have included intensity, repetition, frequency and duration. CONCLUSION: Although therapeutic exercises are considered effective in the management of muscular TMD, the development of randomized clinical trials is necessary, since many existing studies are still based on the clinical experience of professionals.

    To compare vital signs before and after the therapeutic touch observed in hospitalized newborns in neonatal intensive care unit. This was a quasi-experimental study performed at a neonatal intensive care unit of a municipal hospital, in the city of São Paulo (SP), Brazil. The sample included 40 newborns submitted to the therapeutic touch after a painful procedure. We evaluated the vital signs, such as heart and respiratory rates, temperature and pain intensity, before and after the therapeutic touch. The majority of newborns were male (n=28; 70%), pre-term (n=19; 52%) and born from vaginal delivery (n=27; 67%). Respiratory distress was the main reason for hospital admission (n=16; 40%). There was a drop in all vital signs after therapeutic touch, particularly in pain score, which had a considerable reduction in the mean values, from 3.37 (SD=1.31) to 0 (SD=0.0). All differences found were statistically significant by the Wilcoxon test (ptouch promotes relaxation of the baby, favoring reduction in vital signs and, consequently in the basal metabolism rate.

    Nanotechnology-based drug delivery systems can resolve the poor bioavailability issue allied with curcumin. The therapeutic potential of curcumin can be enhanced by making nanocomposite preparation of curcumin with metal oxide nanoparticles, poly lactic-co-glycolic acid (PLGA) nanoparticles and solid lipid nanoparticles that increases its bioavailability in the tissue. Curcumin has manifold therapeutic effects which include antidiabetic, antihypertensive, anticancer, anti-inflammatory and antimicrobial properties. Curcumin can inhibit diabetes, heavy metal and stress-induced hypertension with its antioxidant, chelating and inhibitory effects on the pathways that lead to hypertension. Curcumin is an anticancer agent that can prevent abnormal cell proliferation. Nanocurcumin is an improved form of curcumin with enhanced therapeutic properties due to improved delivery to the diseased tissue, better internalization and reduced systemic elimination. Curcumin has multiple pharmacologic effects, but its poor bioavailability reduces its therapeutic effects. By conjugating curcumin to metal oxide nanoparticles or encapsulation in lipid nanoparticles, dendrimers, nanogels and polymeric nanoparticles, the water solubility and bioavailability of curcumin can be improved and thus increase its pharmacological effectiveness. © 2016 Royal Pharmaceutical Society.

    Matsuki, Kunihiro

    2012-01-01

    The factors necessary to create a reliable therapeutic relationship are presented in this paper. They include a demeanor and calmness of temperament as a psychiatric professional, a feeling of respect for the patient that is based on our common sense as human beings, an attitude of listening attentively to what the patient is revealing, maintaining an attitude of receptive neutrality, the ability to withstand the emotional burdens imposed on one by the patient, patience with any difficulty on one's own part to understand the patient, the ability to communicate clearly, including on the patient's negative aspects, and the ability to end psychiatric consultation sessions in a friendly and intimate manner. Creating a beneficial therapeutic relationship is about the building of a trusting relationship, in which the patient can constructively endure being questioned by us, or cope with the tough burdens we may place on them. However, a reliable relationship such as this contains paradoxes. Patients are able to talk to us about their suspicions, anxieties, dissatisfactions or anger only if the therapeutic relationship is good or based on trust. In other words, just like our patients, psychiatrists, too, must deal with what that the patient brings and directs toward us. It is at this point that what we call a true therapeutic relationship starts.

  19. Tools for predicting the PK/PD of therapeutic proteins.

    Science.gov (United States)

    Diao, Lei; Meibohm, Bernd

    2015-07-01

    Assessments of the pharmacokinetic/pharmacodynamic (PK/PD) characteristics are an integral part in the development of novel therapeutic agents. Compared with traditional small molecule drugs, therapeutic proteins possess many distinct PK/PD features that necessitate the application of modified or separate approaches for assessing their PK/PD relationships. In this review, the authors discuss tools that are utilized to describe and predict the PK/PD features of therapeutic proteins and that are valuable additions in the armamentarium of drug development approaches to facilitate and accelerate their successful preclinical and clinical development. A variety of state-of-the-art PK/PD tools is currently being applied and has been adjusted to support the development of proteins as therapeutics, including allometric scaling approaches, target-mediated disposition models, first-in-man dose calculations, physiologically based PK models and empirical and semi-mechanistic PK/PD modeling. With the advent of the next generation of biologics including bioengineered antibody constructs being developed, these tools will need to be further refined and adapted to ensure their applicability and successful facilitation of the drug development process for these novel scaffolds.

    2012-01-01

    Significant progress has been made in understanding pharmacokinetics (PK), pharmacodynamics (PD), as well as toxicity profiles of therapeutic proteins in animals and humans, which have been in commercial development for more than three decades. However, in the PK arena, many fundamental questions remain to be resolved. Investigative and bioanalytical tools need to be established to improve the translation of PK data from animals to humans, and from in vitro assays to in vivo readouts, which would ultimately lead to a higher success rate in drug development. In toxicology, it is known, in general, what studies are needed to safely develop therapeutic proteins, and what studies do not provide relevant information. One of the major complicating factors in nonclinical and clinical programs for therapeutic proteins is the impact of immunogenicity. In this review, we will highlight the emerging science and technology, as well as the challenges around the pharmacokinetic- and safety-related issues in drug development of mAbs and other therapeutic proteins.

    2010-01-01

    There is an increasing understanding of the role of peptides in normal skin function and skin disease. With this knowledge, there is significant interest in the application of peptides as therapeutics in skin disease or as cosmeceuticals to enhance skin appearance. In particular, antimicrobial peptides and those involved in inflammatory processes provide options for the development of new therapeutic directions in chronic skin conditions such as psoriasis and dermatitis. To exploit their potential, it is essential that these peptides are delivered to their site of action in active form and in sufficient quantity to provide the desired effect. Many polymers permeate the skin poorly and are vulnerable to enzymatic degradation. Synthesis of cyclic peptide derivatives can substantially alter the physicochemical characteristics of the peptide with the potential to improve its skin permeation. In addition, cyclization can stabilize the peptide structure and thereby increase its stability. This review describes the role of cyclic peptides in the skin, examples of current cyclic peptide therapeutic products, and the potential for cyclic peptides as dermatological therapeutics and cosmeceuticals.

    2017-02-01

    Lung cancer is one of the leading causes of cancer-related mortality worldwide. MicroRNAs (miRNAs) are endogenous non-coding small RNAs that repress the expression of a broad array of target genes. Many efforts have been made to therapeutically target miRNAs in cancer treatments using miRNA mimics and miRNA antagonists. Areas covered: This article summarizes the recent findings with the role of miRNAs in lung cancer, and discusses the potential and challenges of developing miRNA-targeted therapeutics in this dreadful disease. Expert opinion: The development of miRNA-targeted therapeutics has become an important anti-cancer strategy. Results from both preclinical and clinical trials of microRNA replacement therapy have shown some promise in cancer treatment. However, some obstacles, including drug delivery, specificity, off-target effect, toxicity mediation, immunological activation and dosage determination should be addressed. Several delivery strategies have been employed, including naked oligonucleotides, liposomes, aptamer-conjugates, nanoparticles and viral vectors. However, delivery remains a main challenge in miRNA-targeting therapeutics. Furthermore, immune-related serious adverse events are also a concern, which indicates the complexity of miRNA-based therapy in clinical settings.

    All therapeutic proteins are potentially immunogenic. Antibodies formed against these drugs can decrease efficacy, leading to drastically increased therapeutic costs and in rare cases to serious and sometimes life threatening side-effects. Many efforts are therefore undertaken to develop therapeutic proteins with minimal immunogenicity. For this, immunogenicity prediction of candidate drugs during early drug development is essential. Several in silico, in vitro and in vivo models are used to predict immunogenicity of drug leads, to modify potentially immunogenic properties and to continue development of drug candidates with expected low immunogenicity. Despite the extensive use of these predictive models, their actual predictive value varies. Important reasons for this uncertainty are the limited/insufficient knowledge on the immune mechanisms underlying immunogenicity of therapeutic proteins, the fact that different predictive models explore different components of the immune system and the lack of an integrated clinical validation. In this review, we discuss the predictive models in use, summarize aspects of immunogenicity that these models predict and explore the merits and the limitations of each of the models.

    Dengue fever is the most prevalent mosquito-borne viral disease globally with about 100 million cases of acute dengue annually. Severe dengue infection can result in a life-threatening illness. In the absence of either a licensed vaccine or antiviral drug against dengue, therapeutic antibodies that neutralize dengue virus (DENV) may serve as an effective medical countermeasure against severe dengue. However, therapeutic antibodies would need to effectively neutralize all four DENV serotypes. It must not induce antibody-dependent enhancement of DENV infection in monocytes/macrophages through Fc gamma receptor (FcγR)-mediated phagocytosis, which is hypothesized to increase the risk of severe dengue. Here, we review the strategies and technologies that can be adopted to develop antibodies for therapeutic applications. We also discuss the mechanism of antibody neutralization in the cells targeted by DENV that express Fc gamma receptor. These studies have provided significant insight toward the use of therapeutic antibodies as a potentially promising bulwark against dengue.

  10. The Epigenome as a therapeutic target for Parkinson's disease

    Full Text Available Parkinson's disease (PD is a common, progressive neurodegenerative disease characterised by degeneration of nigrostriatal dopaminergic neurons, aggregation of α-synuclein and motor symptoms. Current dopamine-replacement strategies provide symptomatic relief, however their effectiveness wear off over time and their prolonged use leads to disabling side-effects in PD patients. There is therefore a critical need to develop new drugs and drug targets to protect dopaminergic neurons and their axons from degeneration in PD. Over recent years, there has been robust evidence generated showing that epigenetic dysregulation occurs in PD patients, and that epigenetic modulation is a promising therapeutic approach for PD. This article first discusses the present evidence implicating global, and dopaminergic neuron-specific, alterations in the methylome in PD, and the therapeutic potential of pharmacologically targeting the methylome. It then focuses on another mechanism of epigenetic regulation, histone acetylation, and describes how the histone acetyltransferase (HAT and histone deacetylase (HDAC enzymes that mediate this process are attractive therapeutic targets for PD. It discusses the use of activators and/or inhibitors of HDACs and HATs in models of PD, and how these approaches for the selective modulation of histone acetylation elicit neuroprotective effects. Finally, it outlines the potential of employing small molecule epigenetic modulators as neuroprotective therapies for PD, and the future research that will be required to determine and realise this therapeutic potential.

    Ethylene oxide (EtO) is widely used in sterilization of drug product primary containers and medical devices. The impact of residual EtO on protein therapeutics is of significant interest in the biopharmaceutical industry. The potential for EtO to modify individual amino acids in proteins has been previously reported. However, specific identification of EtO adducts in proteins and the effect of residual EtO on the stability of therapeutic proteins has not been reported to date. This paper describes studies of residual EtO with two therapeutic proteins, a PEGylated form of the recombinant human granulocyte colony-stimulating factor (Peg-GCSF) and recombinant human erythropoietin (EPO) formulated with human serum albumin (HSA). Peg-GCSF was filled in an EtO sterilized delivery device and incubated at accelerated stress conditions. Glu-C peptide mapping and LC-MS analyses revealed residual EtO reacted with Peg-GCSF and resulted in EtO modifications at two methionine residues (Met-127 and Met-138). In addition, tryptic peptide mapping and LC-MS analyses revealed residual EtO in plastic vials reacted with HSA in EPO formulation at Met-328 and Cys-34. This paper details the work conducted to understand the effects of residual EtO on the chemical stability of protein therapeutics. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association.

  13. Heterogeneity of publicly accessible online critical values for therapeutic drugs

    Directory of Open Access Journals (Sweden)

    Colt M McClain

    2011-01-01

    Full Text Available Introduction: Critical values are reported to clinicians when laboratory values are life threatening and require immediate attention. To date no definitive critical value limit recommendations have been produced regarding therapeutic drug monitoring. Some laboratories choose to publish critical value lists online. These publicly available values may be accessed and potentially utilized by laboratory staff, patient care providers, and patients. Materials and Methods: A web-based search of laboratories associated with the Accreditation Council for Graduate Medical Education pathology residency programs was initiated to determine which therapeutic drugs had critical values and to examine the degree of variation in published critical values for these institutions. Results: Of the 107 institutions with university-based pathology training programs, 36 had published critical values online for review. Thirteen therapeutic drugs were investigated and the number of institutions reporting critical value limits for the drug, as well as the median, range, standard deviation, and the coefficient of variation of critical value concentration limits for each drug were determined. A number of the online critical value limits were deemed to be erroneous, most likely due to incorrectly listed units of measurement. Conclusions: There was a large degree of heterogeneity with regard to the chosen critical value limits for therapeutic drugs. This wide variance in critical values appears to be greater than that observed in interassay proficiency testing. Institutions should reexamine the rationale for their current critical value parameters and ensure that critical value limits and associated units are accurately published online.

    2017-01-01

    Nearly fifty monoclonal antibodies have been approved to date, and the market for monoclonal antibodies is expected to continue to grow. Since global competition in the field of antibody therapeutics is intense, we need to establish novel antibody engineering technologies to provide true benefit for patients, with differentiated product values. Bispecific antibodies are among the next generation of antibody therapeutics that can bind to two different target antigens by the two arms of immunoglobulin G (IgG) molecule, and are thus believed to be applicable to various therapeutic needs. Until recently, large scale manufacturing of human IgG bispecific antibody was impossible. We have established a technology, named asymmetric re-engineering technology (ART)-Ig, to enable large scale manufacturing of bispecific antibodies. Three examples of next generation antibody therapeutics using ART-Ig technology are described. Recent updates on bispecific antibodies against factor IXa and factor X for the treatment of hemophilia A, bispecific antibodies against a tumor specific antigen and T cell surface marker CD3 for cancer immunotherapy, and bispecific antibodies against two different epitopes of soluble antigen with pH-dependent binding property for the elimination of soluble antigen from plasma are also described.

    Full Text Available Abstract Most Spanish prisons provide specialised treatment for incarcerated sex offenders, both rapists and child molesters. This treatment is a cognitive-behavioural intervention that has shown relative effectiveness in previous research. With regard to offenders’ rehabilitation, recidivism assessments are necessary as a final measure of treatment effectiveness. However, the evaluation of recidivism by itself does not provide sufficient information on the treatment process and the specific effects that treated subjects could undergo. This paper aims to analyse the therapeutic effectiveness of psychological treatment provided to rapists (in general, males sentenced for committing a sexual offence against women. To this aim, a group of treated rapists (N=153 serving a sentence in prison was analysed. Using a specially designed scale (PASSO, the global therapeutic change and ten specific variables (including assertiveness, readiness to change, cognitive distortions, impulsivity, etc. were assessed. The within-subjects comparison showed that treated sex offenders improved, in therapeutic terms, globally as well as in most of the specific variables assessed (improvements not experimented by the control group. Also, different therapeutic subscales showed relevant associations between them. The findings regarding treatment effectiveness are discussed.

    Full Text Available In nanomedicine, targeted therapeutic nanoparticle (NP is a virtual outcome of nanotechnology taking the advantage of cancer propagation pattern. Tying up all elements such as therapeutic or imaging agent, targeting ligand, and cross-linking agent with the NPs is the key concept to deliver the payload selectively where it intends to reach. The microenvironment of tumor tissues in lymphatic vessels can also help targeted NPs to achieve their anticipated accumulation depending on the formulation objectives. This review accumulates the application of poly(lactic-co-glycolic acid (PLGA and polyethylene glycol (PEG based NP systems, with a specific perspective in cancer. Nowadays, PLGA, PEG, or their combinations are the mostly used polymers to serve the purpose of targeted therapeutic NPs. Their unique physicochemical properties along with their biological activities are also discussed. Depending on the biological effects from parameters associated with existing NPs, several advantages and limitations have been explored in teaming up all the essential facts to give birth to targeted therapeutic NPs. Therefore, the current article will provide a comprehensive review of various approaches to fabricate a targeted system to achieve appropriate physicochemical properties. Based on such findings, researchers can realize the benefits and challenges for the next generation of delivery systems.

    2004-01-01

    Inpatient psychotherapy includes the patient's manifold contacts with different therapists, nurses and fellow patients. The present study investigated the association between these multiple relationships and therapy outcome. Pre-post measures of symptom load (Brief Symptom Inventory), interpersonal problems (IIP) and self-efficacy (SEB) were used to define three groups with positive (N=129), unchanged (N=44) or negative (N=40) outcome. These groups were compared 1) by their alliance with an individual therapist, their relationship to the therapeutic team, their experience of cohesion and climate concerning fellow patients in the ward (measured weekly by the "Stationserfahrungsbogen" SEB), and 2) by their differences in mean correlations between the courses of relationship experiences and symptom load. Cohesion and relationship to the therapeutic team were not associated with therapy outcome. Therapeutic alliance with the individual therapist and climate among fellow patients turned out to be moderate indicators of the therapeutic outcome. It is recommended to include these process parameters systematically into the process diagnostics of inpatient psychotherapy.

    Sladojevic, Nikola; Yu, Brian; Liao, James K

    2017-12-01

    Stroke is a major cause of disability and the fifth leading cause of death. Currently, the only approved acute medical treatment of ischemic stroke is tissue plasminogen activator (tPA), but its effectiveness is greatly predicated upon early administration of the drug. There is, therefore, an urgent need to find new therapeutic options for acute stroke. Areas covered: In this review, we summarize the role of Rho-associated coiled-coil containing kinase (ROCK) and its potential as a therapeutic target in stroke pathophysiology. ROCK is a major regulator of cell contractility, motility, and proliferation. Many of these ROCK-mediated processes in endothelial cells, vascular smooth muscle cells, pericytes, astrocytes, glia, neurons, leukocytes, and platelets are important in stroke pathophysiology, and the inhibition of such processes could improve stroke outcome. Expert commentary: ROCK is a potential therapeutic target for cardiovascular disease and ROCK inhibitors have already been approved for human use in Japan and China for the treatment of acute stroke. Further studies are needed to determine the role of ROCK isoforms in the pathophysiology of cerebral ischemia and whether there are further therapeutic benefits with selective ROCK inhibitors.

  11. Penicillin: the medicine with the greatest impact on therapeutic outcomes.

    Science.gov (United States)

    Kardos, Nelson; Demain, Arnold L

    2011-11-01

    The principal point of this paper is that the discovery of penicillin and the development of the supporting technologies in microbiology and chemical engineering leading to its commercial scale production represent it as the medicine with the greatest impact on therapeutic outcomes. Our nomination of penicillin for the top therapeutic molecule rests on two lines of evidence concerning the impact of this event: (1) the magnitude of the therapeutic outcomes resulting from the clinical application of penicillin and the subsequent widespread use of antibiotics and (2) the technologies developed for production of penicillin, including both microbial strain selection and improvement plus chemical engineering methods responsible for successful submerged fermentation production. These became the basis for production of all subsequent antibiotics in use today. These same technologies became the model for the development and production of new types of bioproducts (i.e., anticancer agents, monoclonal antibodies, and industrial enzymes). The clinical impact of penicillin was large and immediate. By ushering in the widespread clinical use of antibiotics, penicillin was responsible for enabling the control of many infectious diseases that had previously burdened mankind, with subsequent impact on global population demographics. Moreover, the large cumulative public effect of the many new antibiotics and new bioproducts that were developed and commercialized on the basis of the science and technology after penicillin demonstrates that penicillin had the greatest therapeutic impact event of all times. © Springer-Verlag 2011
