Therapeutic Benefits

Therapeutic effects of Mesenchymal Stem/Stromal Cells (MSCs) transplantation have been observed in various disease models. However, it is thought that MSCs-mediated effects largely depend on the paracrine manner of secreting cytokines, growth factors, and Extracellular Vesicles (EVs). Similarly, MSCs-derived EVs also showed therapeutic benefits in various liver diseases through alleviating fibrosis, improving regeneration of hepatocytes, and regulating immune activity. This review provides an overview of the MSCs, their EVs, and their therapeutic potential in treating various liver diseases including liver fibrosis, acute and chronic liver injury, and Hepatocellular Carcinoma (HCC). More specifically, the mechanisms by which MSC-EVs induce therapeutic benefits in liver diseases will be covered. In addition, comparisons between MSCs and their EVs were also evaluated as regenerative medicine against liver diseases. While the mechanisms of action and clinical efficacy must continue to be evaluated and verified, MSCs-derived EVs currently show tremendous potential and promise as a regenerative medicine treatment for liver disease in the future.

: Nowadays, heterocyclic compounds act as a scaffold and are the backbone of medicinal chemistry. Among all of the heterocyclic scaffolds, 1,4-Dihydropyridine (1,4-DHP) is one of the most important heterocyclic rings that possess prominent therapeutic effects in a very versatile manner and plays an important role in synthetic, medicinal, and bioorganic chemistry. The main aim of the study is to review and encompass relevant studies related to 1,4-DHP and excellent therapeutic benefits of its derivatives. An extensive review of Pubmed-Medline, Embase and Lancet’s published articles was done to find all relevant studies on the activity of 1,4-DHP and its derivatives. 1,4-DHP is a potent Voltage-Gated Calcium Channel (VGCC) antagonist derivative which acts as an anti-hypertensive, anti- anginal, anti-tumor, anti-inflammatory, anti-tubercular, anti-cancer, anti-hyperplasia, anti-mutagenic, anti-dyslipidemic, and anti-ulcer agent. From the inferences of the study, it can be concluded that the basic nucleus, 1,4-DHP which is a voltage-gated calcium ion channel blocker, acts as a base for its derivatives that possess different important therapeutic effects. There is a need of further research of this basic nucleus as it is a multifunctional moiety, on which addition of different groups can yield a better drug for its other activities such as anti-convulsant, anti-oxidant, anti-mutagenic, and anti-microbial. This review would be significant for further researches in the development of several kinds of drugs by representing successful matrix for the medicinal agents.

Significant Health

Diseases of the central nervous system (CNS) remain a significant health, social and economic problem around the globe. The development of therapeutic strategies for CNS conditions has suffered due to a poor understanding of the underlying pathologies that manifest them. Understanding common etiological origins at the cellular and molecular level is essential to enhance the development of efficacious and targeted treatment options. Over the years, neuroinflammation has been posited as a common link between multiple neurological, neurodegenerative and neuropsychiatric disorders. Processes that precipitate neuroinflammatory conditions including genetics, infections, physical injury and psychosocial factors, like stress and trauma, closely link dysregulation in kynurenine pathway (KP) of tryptophan metabolism as a possible pathophysiological factor that ‘fuel the fire’ in CNS diseases. In this study, we aim to review emerging evidence that provide mechanistic insights between different CNS disorders, neuroinflammation and the KP. We provide a thorough overview of the different branches of the KP pertinent to CNS disease pathology that have therapeutic implications for the development of selected and efficacious treatment strategies.

Design Chronic plantar fasciitis (PF) is a common cause of chronic heel pain, with different conventional treatment options. In this randomized clinical trial, the effect of ultrasound-guided injection of dextrose versus corticosteroid in chronic PF was evaluated and compared. Methods A total of 44 patients suffering from chronic PF who visited the physical medicine and rehabilitation clinic were enrolled in the study. Two table-randomized groups were formed. They received an ultrasonography-guided, single injection of either 40 mg methylprednisolone or 20% dextrose. Numeric Rating Scale (NRS), Foot and Ankle Ability Measure questionnaire with 2 subscales, Activities of Daily Living (FAAM-A) and Sports (FAAM-S), along with ultrasonographic parameters were evaluated before and at 2 and 12 weeks after the injection. Results. A total of 40 participants completed the study. Both interventions significantly improved pain and function at 2 and 12 weeks postinjection. After 2 weeks, compared with the dextrose prolotherapy, the corticosteroid group had significantly lower daytime and morning NRS scores (2.55 vs 4.1, P = .012, and 2.75 vs 4.65, P = .004), higher FAAM-S (66.84 vs 54.19; P = .047), and lower plantar fascia thickness at insertion and 1 cm distal to the insertion zone (3.89 vs 4.29 mm, P = .004, and 3.13 vs 3.48 mm, P = .002), whereas FAAM-A was similar in both groups ( P = .219). After 12 weeks, all study variables were statistically similar between corticosteroid and dextrose prolotherapy groups. No injection-related side effects were recorded in either group. Conclusion Both methods are effective. Compared with dextrose prolotherapy, our results show that corticosteroid injection may have superior therapeutic effects early after injection, accompanied by a similar outcome at 12 weeks postinjection.

Tumor Bioenergetics

Resident cancer cells with stem cell-like features induce drug tolerance, facilitating survival of glioblastoma (GBM). We previously showed that strategies targeting tumor bioenergetics present a novel emerging avenue for treatment of GBM. The objective of this study was to enhance the therapeutic effects of dual inhibition of tumor bioenergetics by combination of gossypol, an aldehyde dehydrogenase inhibitor, and phenformin, a biguanide compound that depletes oxidative phosphorylation, with the chemotherapeutic drug, temozolomide (TMZ), to block proliferation, stemness, and invasiveness of GBM tumorspheres (TSs). Combination therapy with gossypol, phenformin, and TMZ induced a significant reduction in ATP levels, cell viability, stemness, and invasiveness compared to TMZ monotherapy and dual therapy with gossypol and phenformin. Analysis of differentially expressed genes revealed up-regulation of genes involved in programmed cell death, autophagy, and protein metabolism and down-regulation of those associated with cell metabolism, cycle, and adhesion. Combination of TMZ with dual inhibitors of tumor bioenergetics may, therefore, present an effective strategy against GBM by enhancing therapeutic effects through multiple mechanisms of action.

Abstract Background Management of triple-negative breast cancer (TNBC) is still challenging because of its aggressive clinical behavior and limited targeted treatment options. Cisplatin represents a promising chemotherapeutic compound in neoadjuvant approaches and in the metastatic setting, but its use is limited by scarce bioavailability, severe systemic side effects and drug resistance. Novel site-directed aptamer-based nanotherapeutics have the potential to overcome obstacles of chemotherapy. In this study we investigated the tumor targeting and the anti-tumorigenic effectiveness of novel cisplatin-loaded and aptamer-decorated nanosystems in TNBC. Methods Nanotechnological procedures were applied to entrap cisplatin at high efficacy into polymeric nanoparticles (PNPs) that were conjugated on their surface with the epidermal growth factor receptor (EGFR) selective and cell-internalizing CL4 aptamer to improve targeted therapy. Internalization into TNBC MDA-MB-231 and BT-549 cells of aptamer-decorated PNPs, loaded with BODIPY505-515, was monitored by confocal microscopy using EGFR-depleted cells as negative control. Tumor targeting and biodistribution was evaluated by fluorescence reflectance imaging upon intravenously injection of Cyanine7-labeled nanovectors in nude mice bearing subcutaneous MDA-MB-231 tumors. Cytotoxicity of cisplatin-loaded PNPs toward TNBC cells was evaluated by MTT assay and the antitumor effect was assessed by tumor growth experiments in vivo and ex vivo analyses. Results We demonstrate specific, high and rapid uptake into EGFR-positive TNBC cells of CL4-conjugated fluorescent PNPs which, when loaded with cisplatin, resulted considerably more cytotoxic than the free drug and nanovectors either unconjugated or conjugated with a scrambled aptamer. Importantly, animal studies showed that the CL4-equipped PNPs achieve significantly higher tumor targeting efficiency and enhanced therapeutic effects, without any signs of systemic toxicity, compared with free cisplatin and untargeted PNPs. Conclusions Our study proposes novel and safe drug-loaded targeted nanosystems for EGFR-positive TNBC with excellent potential for the application in cancer diagnosis and therapy.

: Efficacious treatment for breast cancer is still a challenge despite the presence of various treatment options. Aromatase enzyme present in the breast tissue is responsible for estrogen formation from androgens. Aromatase inhibitors manifest remarkably ameliorated therapeutic efficacy as compared to the current therapeutic options available and exhibit a better safety profile as compared to the other drugs. Clinical resistance to aromatase inhibitors is perceived as a lack of growth inhibition by aromatase inhibitors treatment and cancer therapy becomes ineffective in causing a decrease in the size of the tumor. Naturally extracted aromatase inhibitors have a huge positive impact on vitality and living standards. This review article highlights the particulars about the currently approved steroidal and non-steroidal aromatase inhibitors for clinical use, adverse effects associated with their use and approach to tackling the problem, various strategies to overcome aromatase inhibitors resistance, information on the synthesis of various peculiar aromatase inhibitors which can prove as highly efficient and potent drugs in the near future and the drugs of natural and semi-synthetic origin which can demonstrate to be more efficient, potent and less-toxic than conventional therapy.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Chronic hepatitis B virus (HBV) infection leads to liver disease, cirrhosis, and hepatocellular carcinoma. Globally, an estimated 50% of all hepatocellular carcinoma cases are linked to chronic HBV infection. More than 240 million people are chronically infected, and there are 0.5-1 million deaths per year due to HBVrelated liver conditions. HBV treatment options rarely cure infections and are associated with adverse side effects that often outweigh the potential benefits of treatment. New treatments, therefore, are highly desired for HBV therapy. Towards this goal, we have developed novel compounds targeting two viral targets and assessed the mechanisms of action by which these compounds act. We have developed systems for the discovery and evaluation of compounds that inhibit 2 distinct steps in the HBV life cycle. Using these systems, we have developed potent inhibitors of HBV replication that have potential to become clinically used HBV drugs. Furthermore, we have used our methods to evaluate which properties of these compounds are likely to result in better viral inhibition. The work described in this thesis has led to at least 2 new compound groups for potential use as HBV antivirals and provides insight into mechanisms by which potent antivirals can be achieved.

First Time

AbstractRecently the Norwegian Health Minister ordered the creation of medication-free treatment wards as a result of the lobbying by patients’ groups and activists. The idea behind this is that patients should have the right to choose their treatment, but for the first time, with this arrangement, the user/patient does not choose between treatment options; he literally determines by himself what efficacious treatment is. In our opinion this is another step towards a ‘reverse stigma’ which denies patients the right to be considered as such and eventually kicks them out of the health care system, deprives them of the right for proper treatment and care and instead puts them at the jurisdiction of the much cheaper and ineffective social services.
