New cures

Diffuse large B cell lymphoma (DLBCL), the most frequent subtype of lymphoid malignancy, remains a significant clinical challenge, as approximately 30% of patients are not cured. Over the past decade, remarkable progress has been made in the understanding of the pathogenesis of this disease, spurred by the implementation of powerful genomic technologies that enabled the definition of its genetic and epigenetic landscape. These studies have uncovered a multitude of genomic alterations that contribute to the initiation and maintenance of the tumor clone by disrupting biological functions known to be critical for the normal biology of its cells of origin, germinal center B cells...

Background & objectives: The existing antileishmanial drugs for complete cure of visceral leishmaniasis (kala-azar) are limited. The available drugs are either toxic or less effective leading to disease relapse or conversion to post-kala-azar dermal leishmaniasis. Several herbal extracts have been shown to have antileishmanial activity, but a herbal drug may not always be safe. In the present study, the extract of Cedrus deodara leaves has been standardized and tested for immunomodulatory antileishmanial activities...

Experimental Bis-EFMA-based resin (Bis-EFMA/TEGDMA=50/50, wt./wt.) and composite were prepared. Critical properties were investigated according to standard or referenced methods Bis-GMA/TEGDMA (50/50, wt...

Purpose: The first line treatment of diffuse large B-cell lymphoma (DLBCL) is the combination of rituximab with CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy, curing approximately 60% of patients. Many clinical trials have been performed over the last 10 years trying to improve the results of this treatment, but the appropriateness of their planning strategies could be rediscussed. Patients and Methods: Reports of phase 3 trials evaluating the addition of molecularly targeted agents (MTA) or new monoclonal antibodies to the classic R-CHOP backbone in first-line induction or maintenance treatment were reviewed...

Background: Research in chlamydial genetics is challenging because of its obligate intracellular developmental cycle. In vivo systems exist that allow studies of different aspects of basic biology of chlamydiae, the murine Chlamydia muridarum model is one of great importance and thus an essential research tool. C. muridarum carries a plasmid that has a role in virulence.  Our aim was to compare and contrast the C. muridarum plasmid-free phenotype with that of a chromosomally isogenic plasmid-bearing strain, through the inclusion phase of the developmental cycle...

Aim: The aim of this study was to investigate the effects of using a commercially-available polyvalent mastitis vaccine on the bacteriological cure rate of existing subclinical mastitis in Awassi sheep. Materials and Methods: A total of 164 lactating ewes were divided into two main groups according to udder health and milk somatic cell count (SCC): Group 1=normal (N; n=80) and Group 2=subclinical mastitis (SC; n=84). Each group was then subdivided randomly into two treatment groups: N vaccinated (Nvax ; n=38), N non-vaccinated (Nnvax ; n=42), SC vaccinated (SCvax ; n=42), and SC non-vaccinated (SCnvax ; n=42)...

A key goal in the control of canine visceral leishmaniosis (CVL) has been the development of vaccines with a highly protective capability to interrupt the parasite transmission cycle. However, in addition to promising vaccine searches, researchers have sought to develop new drugs capable of eliminating parasites in humans and dogs. With that in mind, this study analyzed an immunotherapeutic approach in dogs naturally infected with Leishmania infantum. Fourteen dogs were divided into two groups and received a protocol of immunotherapeutic treatment with five doses of total antigens of Leishmania amazonensis or total antigens of L...

This study investigated the effect of different electrolyzed water (EO) solutions, including acidic electrolyzed water (AEW) and neutral electrolyzed water (NEW), alone and in combination with mild thermal processing (50, 55, 60, 65 °C) at different exposure times (2, 6, 10 min) on the reduction of Listeria monocytogenes on Atlantic salmon fillets. The effects of the EO water solutions on cell wall structures of L. monocytogenes and on the secondary structure of salmon protein were studied using Fourier Transform Infra-Red (FTIR) spectroscopy...

Cryptococcus neoformans is one of the most lethal fungi causing mortality across the globe with the highest incidences in immuno-compromised person. Patients taking immuno-suppressive medications and immuno-competent hosts are extremely susceptible to its infection. Thus, new forms of therapy are urgently required for effective cure to the fungal burden. So, in the present study we have tried to explore the potential effects of amphotericin B (AMB) and fluconazole (FLC) in combination antifungal drug therapy...

Despite great advances in understanding of molecular pathogenesis and achievement of a high cure rate in medulloblastoma, recurrent medulloblastomas are still dismal. Additionally, misidentification of secondary malignancies due to histological ambiguity leads to misdiagnosis and eventually to inappropriate treatment. Nevertheless, the genomic characteristics of recurrent medulloblastomas are poorly understood, largely due to a lack of matched primary and recurrent tumor tissues. We performed a genomic analysis of recurrent tumors from 17 pediatric medulloblastoma patients...

BACKGROUND: Bonding of orthodontic brackets to teeth is important to enable effective and efficient treatment with fixed appliances. The problem is bracket failure during treatment which increases operator chairside time and lengthens treatment time. A prolonged treatment is likely to increase the oral health risks of orthodontic treatment with fixed appliances one of which is irreversible enamel decalcification. This is an update of the Cochrane Review first published in 2003. A new full search was conducted on 26 September 2017 but no new studies were identified...

Purpose: The purpose of this study is to compare the physical, mechanical, and biocompatibility properties of a new dual-cure white mineral trioxide aggregate (D-W-MTA) and a commercial W-MTA. Materials and Methods: Diametral tensile strength (DTS), water sorption (WSp), and water solubility (WSl) tests were performed. Cytotoxicity was observed in primary culture of human pulp fibroblasts (HPFs) and mouse 3T3/NIH fibroblast lineage. Specimens of both materials were embedded in 1 mL of Dulbecco's modified essential medium for 24 h...

BACKGROUND: Replacement therapy for hemophilia remains a lifelong treatment. Only gene therapy can cure hemophilia at a fundamental level. The clustered regularly interspaced short palindromic repeats-CRISPR associated nuclease 9 (CRISPR-Cas9) system is a versatile and convenient genome editing tool which can be applied to gene therapy for hemophilia. METHODS: A patient's induced pluripotent stem cells (iPSCs) were generated from their peripheral blood mononuclear cells (PBMNCs) using episomal vectors...

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive fibrotic lung disease for which there is no cure. Current therapeutics are only able to slow disease progression, therefore there is a need to explore alternative, novel treatment options. There is increasing evidence that the 3', 5' cyclic adenosine monophosphate (cAMP) pathway is an important modulator in the development of fibrosis, with increasing levels of cAMP able to inhibit cellular processes associated with IPF...

New drugs for treating hepatitis C have considerably increased the probability of being cured. Treatment uptake, however, is still low. The objectives of this study were to analyse the impact of initiatives that may increase the proportion of infected people on treatment and interventions aimed at reducing the incidence of new infection among people who inject drugs. A compartmental model for Norway was used to simulate hepatitis C and related complications. We analysed two different screening initiatives aimed to increase the proportion of infected people on treatment...

Patients receiving hemodialysis are at increased risk of hepatitis C virus (HCV) infection, and routine screening is recommended. Highly effective HCV treatments for dialysis patients are newly available and cure >90% of patients in 12 weeks. Dialysis facilities should screen individuals for HCV, confirm infections, and treat or link patients to care and treatment. The New York City (NYC) Department of Health and Mental Hygiene electronically receives all positive HCV antibody and all positive and negative HCV RNA tests for NYC residents...

Gene therapy for severe hemophilia is on the cusp of entering clinical practice. However, there is limited clinical experience in this area given that gene transfer is a relatively recent technology. Therefore, this clinical perspective article will review the evidence supporting gene therapy in this field, examine ways to open a dialogue about gene therapy with patients in the clinic setting, and present a case of a participant in a recent clinical trial of gene therapy for hemophilia. Clinical trials in hemophilia using adeno-associated virus (AAV) vectors to transfer functional factor IX (FIX) have reported increases in FIX activity to functional levels, reduced bleed frequency, and a lessening or abrogation of the need for costly FIX replacement...

Colorectal cancer (CRC) is the third most incident cancer worldwide. Most of CRC patients will develop distant metastases, mainly to the liver, and liver resection is the only potential chance for cure. On the other hand, only a small proportion of patients with hepatic CRC metastasis are candidates for upfront liver resection. Liver transplantation (LT) is an attractive option for patients with nonresectable CRC liver metastases (NRCLM) without extrahepatic involvement. Initial experiences with LT for NRCLM achieved very poor outcomes, with a 5-year overall survival (OS) lower than 20%...

In this study, an injectable, photo-curable gelatin system, consisting of acrylated gelatin and thiolated gelatin, with tunable mechanical, biodegradation and biological properties was used as a potential cell supportive scaffold for the repair of focal corneal wounds. The mechanical property of hydrogels can be readily modified (post-cure shear modulus of between 0.3 and 22 kPa) by varying the ratio of acrylate to thiol groups, photo intensity and solids content, and the biodegradation times also varied with change of solids content...
