BACKGROUND AND AIMS: Phytosterolemia is a rare genetic disease caused by mutation of the ABCG5/8 gene. Our aim was to elucidate the natural history and homeostasis of phytosterolemia. METHODS: We analyzed a Hutterite kindred consisting of 21 homozygotes with phytosterolemia assembled over a period of two decades, all of whom carried the ABCG8 S107X mutation and were treated with ezetimibe. RESULTS: Most of these subjects were asymptomatic and devoid of clinical stigmata, and this, since they were ascertained primarily by a process of cascade testing, suggests that, relative to its true prevalence, phytosterolemia is a condition of low morbidity...

Psychiatric evaluations of violent political crime were mostly performed on a case-by-case basis in a forensic environment, which made them unduly dependent on categories of presumed dangerousness and legal responsibility, rather than on a clinical definition of their mental status. In referring to such "clinical" definitions, the disorder we have in mind is not limited to the major, agitated psychotic manias or mixed states. The presence of a dominant temperament, or protracted hypomania, is enough by itself to explain an individual's engagement in a wide range of activities, not necessarily sociopathic or violent...

Purpose: Differentiated thyroid cancer (DTC) accounts for approximately 95% of thyroid carcinomas. In the metastatic RAI-refractory disease, chemotherapy has very limited efficacy and is associated with substantial toxicity. With increasing knowledge of the molecular pathogenesis of DTC, novel targeted therapies have been developed. Lenvatinib is a tyrosine kinase inhibitor (TKI) with promising clinical activity based on the randomized phase III SELECT trial. In Switzerland, a Named Patient Program (NPP) was installed to bridge the time gap to Swissmedic approval...

Heat shock factor 1 (HSF1) is a transcriptional factor that determines the efficiency of heat shock responses (HSRs) in the cell. Given its function has been extensively studied in recent years, HSF1 is considered a potential target for the treatment of disorders associated with protein aggregation. The activity of HSF1 is traditionally regulated at the transcriptional level in which the transactivation domain of HSF1 is modified by extensive array of pos-translational modifications, such as phosphorylation, sumoylation, and acetylation...

Chemoresistance is a critical challenge in the clinical treatment of triple-negative breast cancer (TNBC). It has been well documented that inflammatory mediators from tumor microenvironment are involved in the pathogenesis of TNBC and might be related to chemoresistance of cancer cells. In this study, the contribution of interleukin-6 (IL-6), one of the principal oncogenic molecules, in chemoresistance of a TNBC cell line MDA-MB-231 was first investigated. The results showed that IL-6 treatment could induce upregulation of HIF-1α via the activation of STAT3 in MDA-MB-231 cells, which consequently contributed to its effect against chemotherapeutic drug-induced cytotoxicity and cell apoptosis...

A biosimilar is a biologic product that is similar to a reference biopharmaceutical product, the manufacturing process of which hinders the ability to identically replicate the structure of the original product, and therefore, it cannot be described as an absolute equivalent of the original medication. The currently available technology does not allow for an accurate copy of complex molecules, but it does allow the replication of similar molecules with the same activity. As biosimilars are about to be introduced in oncology practice, these must be evaluated through evidence-based medicine...

Hypoxia (ie. oxygen deprivation) activates the hypoxia-signaling pathway, primarily via hypoxia inducible transcription factors (HIF) for numerous target genes, which mediate angiogenesis, metabolism, coagulation, among other processes to try to replenish tissues with blood and oxygen. Hypoxia signaling dysregulation also commonly occurs during chronic inflammation. We sampled gingival tissues from rhesus monkeys (M. mulatta; 3-25 years old) and total RNA was isolated for microarray analysis. HIF1A, HIF1B, and HIF2A were significantly different in healthy aged tissues, and both HIF1A and HIF3A were positively correlated with aging...

"Organ reserve" refers to the ability of an organ to successfully return to its original physiological state following repeated episodes of stress. Clinical evidence shows that organ reserve correlates with the ability of older adults to cope with an added workload or stress, suggesting a role in the process of aging. Although organ reserve is well documented clinically, it is not clearly defined at the molecular level. Interestingly, several metabolic pathways exhibit excess metabolic capacities (e.g., bioenergetics pathway, antioxidants system, plasticity)...

BACKGROUND: The blood-brain barrier (BBB) severely limits the entry of systemically administered drugs including chemotherapy to the brain. In rodents, regadenoson activation of adenosine A2A receptors causes transient BBB disruption and increased drug concentrations in normal brain. This study was conducted to evaluate if activation of A2A receptors would increase intra-tumoral temozolomide concentrations in patients with glioblastoma. METHODS: Patients scheduled for a clinically indicated surgery for recurrent glioblastoma were eligible...

Alzheimer's disease (AD) is a fatal neurodegenerative disorder, having a complex aetiology with numerous possible drug targets. There are targets that have been known for years while more new targets and theories have also emerged. Beta amyloid and cholinesterases are the most significant biological targets for finding curative treatment of AD. The major class of drugs used for AD till now has been the Cholinesterase (ChE) inhibitors. Other prevailing models of molecular pathogenesis in AD include neurofibrillary tangles (NFTs) and amyloid deposition, tryptophan degradation pathway, kinase and phosphatase activity imbalance and neuroinflammation...

Recent studies report that loss and dysfunction of mitochondria and peroxisomes contribute to the myelin and axonal damage in multiple sclerosis (MS). In this study, we investigated the efficacy of lovastatin and AMPK activator (AICAR) combination on the loss and dysfunction of mitochondria and peroxisomes and myelin and axonal damage in the spinal cords, relative to the clinical disease symptoms, using a mouse model of experimental autoimmune encephalomyelitis (EAE, a model for MS). We observed that lovastatin and AICAR treatments individually provided partial protection of mitochondria/peroxisomes, myelin/axons, and thus partial attenuation of clinical disease in EAE mice...

Measurable residual disease (MRD, previously termed minimal residual disease) is an independent, post-diagnosis, prognostic indicator in acute myeloid leukemia (AML) that is important for risk stratification and treatment planning, in conjunction with other well-established clinical, cytogenetic, and molecular data assessed at diagnosis. MRD can be evaluated using a variety of multi-parameter flow cytometry (MFC) and molecular protocols but, to date, these approaches have not been qualitatively or quantitatively standardized, making their use in clinical practice challenging...
