Biography:

For 25 years, he has been developing gene and cell therapy using non-human primates, immune-tolerant mice and rats to protect against the side effects of radiation. He collaborates with clinicians to develop  strategies for treatment of patients after radiotherapy overexposures. He has participated in the first establishment of proof of concept of the therapeutic efficacy of Mesenchymal stem cells (MSCs) for the treatment of hematopoietic deficit, radiodermatitis and over dosages of radiotherapy. He has contributed to the first reported correction of deficient hematopoiesis in patients (graft failure and aplastic anemia) thanks to intravenous injection of MSCs restoring the bone marrow microenvironment, mandatory to sustain hematopoiesis after total body irradiation. He is scientific investigator of Clinical phase II trial evaluating the efficacy of systemic MSC injections for the treatment of severe and chronic radiotherapy-induced abdomino-pelvic complications refractory to standard therapy (NCT02814864Hirsch Index 26.

Abstract:

The late adverse effects of pelvic radiotherapy concern 5 to 10% of them, which could be life threatening. However, a clear medical consensus concerning the clinical management of such healthy tissue sequelae does not exist. Our group has demonstrated in preclinical animal models that systemic MSC injection is a promise approach for the medical management of gastrointestinal disorder after irradiation. We have shown that MSC migrate to damaged tissues and restore gut functions after irradiation.

The clinical status of four first patients suffering from severe pelvic side effects resulting from an over-dosage was improved following MSC injection in a compassional situation. A quantity of 2x106 - 6x106 MSC /kg were infused intravenously to the patients. Pain, hemorrhage, frequency of diarrheas and fistulisation as well as the lymphocyte subsets in peripheral blood were evaluated before MSC therapy and during the follow-up. Two patients revealed a substantiated clinical response for pain and hemorrhage after MSC therapy. In one patient pain reappeared after 6 months and again substantially responded on a second MSC infusion. A beginning fistulisation process could be stopped in one patient resulting in a stable remission for more than 3 years of follow-up. The frequency of painful diarrhea diminished from an average of 6/d to 3/d after the first and 2/d after the 2nd MSC injection in one patient. In all patients, prostate cancer remained in stable complete remission. A modulation of the lymphocyte subsets towards a regulatory pattern and diminution of activated T cells accompanies the clinical response in refractory irradiation-induced colitis. No toxicity occurred.

MSC therapy was safe and effective on pain, diarrhea, haemorrhage, inflammation, fibrosis and limited fistulisation. For patients with refractory chronic inflammatory and fistulising bowel diseases, systemic MSC injections represent a safe option for salvage therapy. A clinical phase  II trial will start in 2018

She is working to research drug delivery system using graphene quantum dots. She is also leading a project to develop drug delivery vehicles to treat specific breast cancer.

Abstract:

Graphene Quantum Dots (GQD) have been widely used for theragnosis for cancer disease. However, one of the current challenges is considerably difficult to release therapeutic agent to target site. In this study, we modified GQD that introduced herceptin through polyethylene glycol (PEG) and disulfide bond to induce active targeting for specific cells and control the drug release. The resulting of UV spectroscopy, Fluorescence, Fourier Transform Infrared showed that GQD-complex (GQD-comp) was conjugated successfully. The cell viability was presented that GQD-comp had a substantial effect on HER2-overexpressing breast cancer cells. In endosomal condition of low pH and high glutathione, doxorubicin was rapidly released from Doxorubicin loaded GQD-comp. Besides, this optical imaging by confocal laser scanning microscopy indicated to certainly confirm intracellular trafficking. In conclusion, GQD-comp had potential theragnostic agents to HER2-positive breast cancer cells.

Abstract:

Poly(lactide-co-glycolide) (PLGA) is a biocompatible and biodegradable polymer that has been widely used in devices for tissue engineering and drug delivery applications. Gold nanoparticles (GNPs) have also been used as biomaterials and have been found to have a positive effect on bone formation. In this study, we synthesized thiol end-capped PLGA (PLGA-SH) and used it for binding GNPs. This PLGA was processed into a sheet form via electrospinning. GNPs with an approximate size of 30 nm were attached onto the PLGA-SH sheet surfaces (PLGA-GNPs). This membrane was characterized by thermogravimetric analysis, ultraviolet/visible spectrophotometry, field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and confocal laser scanning microscopy. Characterization results show that the GNPs are well attached on the PLGA-SH sheet and it is possible to control the GNPs load. Additionally, in-vitro results showed that PLGA-GNPs have good biocompatibility. They were also found to enhance osteogenic differentiation of human adipose derived stem cells. From these results, we have determined that the PLGA-GNP fibers can be useful as materials for bone regeneration and can also potentially serve as drug carriers.

Abstract:

The purpose of study is to explore the efficacy and safety of platelet rich plasma (PRP) in the non-operative management of shoulder tendinopathy amongst individuals with spinal cord injury.

In this case in road traffic accidents that cause spinal injuries to the central nervous system, which increased morbidity and motility. The complications in patients were developed, resulting to a challenging problem for medicine. Platelet is naturally involved in haemostasis and tissue healing processes due to their content in growth factor and other bioactive molecules. Basic science and preclinical evidence supports the use of platelet derived growth factors as well as of PRP for enhancing reparatory processes in spinal cord injury.

In recent advancement in the field of regenerative medicine it was thought that this would grant a new approach to this problem, as it had proven beneficial in the repair of peripheral nerve injuries and their regeneration. This study was done to evaluate the effect of Platelet Rich Plasma (PRP) and its effect on the spinal cord post trauma. Subsequently, it was seen that PRP proved beneficial with marked positive effects in both muscle tone and muscle control and marked clinical improvement, although it can still be said that further research must be done in this field.

Clinical results about the use of PRP for bone, tendon, cartilage or spinal cord healing are encouraging and continue to accumulate in the recent years. Proteomic profiling and biomarker based PRP characterization have the potential of advancing the field of PRP application. High quality studies are awaited in order to enable clear cut therapeutic indications.

Abstract:

Three series of N-alkylammonium salts (7a-c, 8a-b, 9a-b) based on quaternary ammonium compounds with a different length and type of carbon chain (C₁₂, C₁₄, C₁₆) were synthesized, characterized (EA, HRMS, NMR) and tested in vitro for antimicrobial (antibacterial, antifungal and antialgal) activity. Furthermore, the critical micelle concentration (CMC), capacity factors k and cytotoxicity were likewise measured to elucidate possible structure-activity relationships. The antimicrobial activity of the prepared compounds has been evaluated and compared. All compounds being tested proved high efficacy against both Gram-positive and Gram-negative bacterial strains, excluding the activity against multi-resistant Pseudomonas aeruginosa. Antifungal testing showed high activity of most compounds against fungal strains (yeasts and filamentous fungi) except of Aspergillus niger. The relationship between length of carbon chain and the efficiency has been observed. Series 7a-c proved high antialgal efficacy. Cell viability assay confirmed an expected trend that increasing carbon chain length results in higher cytotoxicity.

Abstract:

Electron microscopy used to investigate the detailed structure and configuration of the mycobacteria which may lead to an understanding the role of  infections  and in transmitting the diseases. In the natural world more than 99% of bacteria exist as biofilms and according to NIH report more then 68% of all human infections are associated with  biofilms formation. Biofilms are slimy, glue-like substance that excreted by bacteria and aggregate on living surface. Biofilms are formed to protect the bacteria from host defences, antibiotics and from harsh environmental conditions. Biofilms are found almost everywhere in nature, including soil, water pipes, and even inside the human body. Many Mycobacteria  can develop biofilm, a multicellular structure largely combining bacteria and their extracellular polymeric substances (EPS). The formation of biofilm results in an alternative existence in which microbes ensure their survival in adverse environments. Bacterial biofilms are often associated with  infections specially with medical implants such as catheters and other medical devices. Attachment of mycobacteria involved in biofilm formation in the liquid air interface is a complex process, with many variables such as pH, nutrient levels, iron, oxygen, ionic strength and temperature, affecting the outcome.

We had taken two mycobacterial species for study of Mycobacterial biofilm. The isolates were subcultured and characterized biochemically and molecularly. M.avium developed strong amount of biofilm at 30^oC and 42^oC  as compared to 37⁰C. M tuberculosis (H37Rv) developed strong biofilm at 37⁰C  and no biofilm at 30⁰C and 42⁰C in MB 7H9 media and Sauton’s media. The selected non tuberculosis mycobacteria  and  H37Rv developed strong biofilm in the presence of OADC enrichment in MB7H9   as well as Sauton’s medium. Isoniazid showed strong inhibited  biofilm in fast grower and sensitive isolates. However, Pyrazinamide and Isoniazid  inhibited  biofilm of M.tuberculosis (H37Rv) and in MDR isolates Ethionamide and Moxifloxacin inhibited biofilm in slow grower and fast grower Mycobacteria. However, many  mycobacterial species are known to form biofilms, little is known about either  the genetic requirements, patterns of gene expression. In micro array hybridisation we have found that six genes were  expressed in M.avium.  In M. tuberculosis MDR isolates seven genes were expressed and two genes Rv0359 and Rv3526 were homologus as earlier reported in  P. areuginosa and M. avium  which might be responsible for biofilm formation.

Abstract:

Enterococcus faecalis is Gram-positive, catalase-negative, non-spore-forming, facultative anaerobic bacteria, which usually inhabit the alimentary tract of humans in addition to being isolated from environmental and animal sources. They are able to survive hostile environments, such as in extreme temperature (5-65⁰C), pH (4.5-10.0) and high NaCl concentration, enabling them to colonize a wide range of niches. Depending on the site of infection this organism colonizes, invades the host tissue using their surface adhensin causing pathological changes in the host.  Enterococcus faecalis is the leading causative agent of serious nosocomial infections such as urinary tract infection (UTIs), endocarditis, bacteremia, intra-abdominal and intra-pelvic abscesses. This organism may frequently be acquired by cross-infection from other patients and through contaminated medical equipments. Diseases cause by this organism can be treated with antibiotics such as gentamycin, vancomycin and daptomycin. Cautious use of antibiotics and implementation of infection control measures are ways of preventing this infection. Understanding the pathogenicity and antibiotics resistance of this organism will help in preventing it from causing nosocomial infection
