Treatment Needs and Service Delivery for Patients with Dual Disorders During the COVID-19 Pandemic: Findings From the WADD Survey
2021
Objective: The COVID-19 pandemic has posed a great challenge for the existing health systems. The restrictions imposed across countries on the movement of people and the realignment of health care services in response to the pandemic are likely to negatively affect the health status and delivery of mental health services to persons with dual disorders (PWDD). Methods: An online survey was conducted among mental health professionals involved in providing care to PWDD to better understand the problems encountered and identify potential solutions in providing continued treatment for PWDD during the COVID-19 pandemic. Results: The findings confirmed significant disruption in the delivery of tre…
State of Training, Clinical Services, and Research on Dual Disorders Across France, India, Israel, and Spain.
2016
This article overviews training, clinical services, and research on dual disorders across four countries: France, India, Israel, and Spain.The current dual disorders systems in each of the four countries were reviewed, with a focus on strengths and limitations of each.In France, psychiatric care occurs within the public health care system and involves little training of medical graduates for managing dual disorders. Special courses and forums for specialists have recently started to meet the growing interest of physicians in learning how to manage dual disorders. The Indian health care system grapples with a large treatment gap for mental disorders, and while some treatment services for dua…
Low RNA translation activity limits the efficacy of hydrodynamic gene transfer to pig liver “in vivo”
2014
Background Hydrodynamic gene delivery has proved an efficient strategy for nonviral gene therapy in the murine liver but it has been less efficient in pigs. The reason for such inefficiency remains unclear. The present study used a surgical strategy to seal the whole pig liver in vivo. Methods A solution of enhanced green fluorescent protein (eGFP) DNA was injected under two different venous injection conditions (anterograde and retrograde), employing flow rates of 10 and 20 ml/s in each case, with the aim of identifying the best gene transfer conditions. The gene delivery and information decoding steps were evaluated by measuring the eGFP DNA, mRNA and protein copy number 24 h after transf…

Candida and Candidiasis: The Cell Wall as a Potential Molecular Target for Antifungal Therapy
2004
The fungal species Candida albicans is an opportunistic pathogen, which causes serious infections in humans, particularly in immunocompromised patients. Depending on the underlying host defect, C. albicans causes a variety of infections, ranging from superficial mucocutaneous candidiasis to life-threatening disseminated infections. Both the limited spectrum of antifungal drugs currently in clinical use and the emergence of resistances make necessary the development of new effective antifungal drugs with minimal side effects; however, such a research is limited by the small number of specific target sites identified to date. The cell wall is a fungal specific dynamic structure essential to a…
New methods of delivery of amphotericin B.
1993
Fungal infections continue to be a major problem in the management of immunocompromised patients. Despite its formidable toxicity and treatment failures, amphotericin B is still the drug of choice for most of these infections. One strategy for reducing the toxicity of amphotericin B and thus permitting administration of higher doses is that of using less toxic formulations. Entrapping amphotericin B into liposomes or binding it to other substances reduces its toxicity to host cells, whereas the selective binding of amphotericin B to ergosterol preserves its toxicity to fungal cells. Adding fungus-specific antibodies to such liposomes may further increase the efficiency of drug targeting. Th…
Comparison of Delivery Methods in Phage Therapy against Flavobacterium columnare Infections in Rainbow Trout
2021
Viruses of bacteria, bacteriophages, specifically infect their bacterial hosts with minimal effects on the surrounding microbiota. They have the potential to be used in the prevention and treatment of bacterial infections, including in the field of food production. In aquaculture settings, disease-causing bacteria are often transmitted through the water body, providing several applications for phage-based targeting of pathogens, in the rearing environment, and in the fish. We tested delivery of phages by different methods (via baths, in phage-coated material, and via oral delivery in feed) to prevent and treat Flavobacterium columnare infections in rainbow trout fry using three phages (FCOV…
EMPLOYMENT OF CATIONIC SOLID-LIPID NANOPARTICLES AS RNA CARRIERS
2007
Gene transfer represents an important advance in the treatment of both genetic and acquired diseases. In this article, the suitability of cationically modified solid-lipid nanoparticles (SLN) as a nonviral vector for gene delivery was investigated, in order to obtain stable materials able to condense RNA. Cationic SLN were produced by microemulsion using Compritol ATO 888 as matrix lipid, Pluronic F68 as tenside, and dimethyldioctadecylammonium bromide (DDAB) as cationic lipid. The resulting particles were approximately 100 nm in size and showed a highly positive surface charge (+41 mV) in water. Size and shape were further characterized by scanning electron microscopy (SEM) measurements. M…
Dual-capillary electroencapsulation of mesoporous silicon drug carrier particles for controlled oral drug delivery
2012
Abstract The feasibility of electroencapsulation of mesoporous silicon (PSi) micro- and nanoparticles as a method to seal the PSi particles in mechanically processable solid units, and to facilitate time and site specific drug release from the pores of PSi particles, is of interest in the present work. Suitable microcapsules and micromatrix particles were produced in a single-step process using a setup with two electrospraying nozzles kept at high electric potentials of opposite polarities. The structures of the produced particles were analyzed by microscope and X-ray micro- and nanotomography imaging, and optimization of the electroencapsulation process production efficiency is discussed.
