Unapproved stem-cell treatments touted on federal database ClinicalTrials.gov, study says

Stem cell clinics offering unapproved treatments for ailments from hip pains to autism to erectile dysfunction increasingly are using a federal clinical-trials database as a marketing tool — a strategy that confuses patients and exposes them to “unjustifiable” safety risks and high costs, according to a new study. At least 18 purported clinical trials — […]Related:‘How did this happen to a 10-year-old?’: Child dies with heroin and fentanyl in his systemWhy this adorable mouse is to blame for the spread of Lyme diseaseNew NIH report finds low morale, continued patient safety concerns

In the present study, GO films were fabricated on titanium surface by cathode electrophoretic deposition with the help of Mg2+ and Al3+. Responses of rat bone marrow mesenchymal stem cells to GO films with different alkali treatment, including urea hydrothermal treatment and sodium hydroxide hydrothermal treatment, were investigated. The results indicated that GO ...

KempAbstractThe ATR protein kinase is known to protect cells from DNA damage induced during the replicative phase of the cell cycle. Small molecule ATR kinase inhibitors have therefore been developed to improve the effectiveness of DNA damage-based chemotherapy regimens aimed at killing rapidly proliferating tumor cells. However, whether ATR functions in a similar manner in non-replicating cells has not been examined and is important considering the fa...

ElsässerSummaryTo understand the epigenomic foundation of naive pluripotency, we implement a quantitative multiplexed chromatin immunoprecipitation sequencing (ChIP-seq) method comparing mouse embryonic stem cells (ESCs) grown in 2i versus 2i/serum and serum conditions. MINUTE-ChIP has a large linear dynamic range for accurately quantifying relative differences in genome-wide histone modification patterns across multiple pooled samples. We find compelling evidence for a broad H3 lysine 27 trimethylation (H3...

We report a high-content screen for small-molecule regulators of the axonal transport of mitochondria. Six compounds enhanced mitochondrial transport in the sub-micromolar range, acting via three cellular targets: F-actin, Tripeptidyl peptidase 1 (TPP1), or Aurora Kinase B (AurKB). Pharmacological inhibition or small hairpin RNA (shRNA) knockdown of each target promotes mitochondrial axonal transport in rat hippocampal neurons and induced pluripotent stem cell (iPSC)-derived human cortical neurons and enhances mitochondrial transport in iPSC-derived motor neurons from an amyotrophic lateral sclerosis (ALS) patient bearing ...

ConclusionsWe conclude that AATG is a promising and safe modality for the treatment of the painful scar. There is an abundance of low-level evidence to support its use as an alternative treatment but there is a lack of high-level evidence at present to support its standard use. Future long-term randomized controlled trials with analgesic scores as the primary outcome measures are required to assess long-term efficacy.

In conclusion, the current study provides evidence for a neuroprotective effect of LER and/or BM-MSCs in 3-NP-induced neurotoxicity in rats. Interestingly, combined LER/BM-MSC therapy was superior to cell therapy alone in inhibiting 3-NP-induced neurological insults via modulation of the Ca2+/CaN/NFATc4 and Wnt/β-catenin signalling pathways. LER/BM-MSC combined therapy may represent a feasible approach for improving the beneficial effects of stem cell therapy in HD.

Chem Biol Interact. 2019 Sep 25;311:108758 Authors: Mirza R, Sharma B Abstract Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder in children. It is diagnosed by two main behavioral phenotypes i.e. social-communication impairments and repetitive behavior. ASD is complex disorder with unsolved etiology due to multiple genes involvement, epigenetic mechanism and environmental factors. The c...

Localized prostate cancer (PCa) has a high cure rate of 95.5%. PCa patients receive radiation therapy (RT) as a standard of care treatment. However, the major concern is the treatment-related side effects compromising the quality of life (QoL) in PCa patients. Radiation-induced Erectile Dysfunction (RiED) is a common and irreversible late side effect of RT, that develops in more than half of PCa patients. There is no FDA approved drug to treat RiED. Phosphodiesterase type 5 inhibitors (PDE5i) are the most common pharmacological agents being used to treat RiED.
