Melanoma is a highly aggressive skin cancer with high incidence worldwide. There is growing evidence that aberrantly expressed non-coding RNAs (ncRNAs) play a role in the development, progression and dissemination of melanoma tumor cells. Among the many types of ncRNAs described in this review, the functions of micro- and long non-coding RNAs are described and related to the six hallmarks of cancer. Recently, ncRNAs discovered in body fluids have become known as one of the most promising groups of oncological bioma [...]

It is important to understand the band offsets between semiconductors, which are crucial to determine the direction of electron transfer at the interfaces. Two methods are normally used to determine the direction from the first principles: alternating slabs put in contact (without empty spaces between them) and separate calculations for each material surface in the presence of vacuum spaces. The first method may introduce distortions due to insufficient epitaxial match, which may lead to bandgap changes, and the se [...]

Studies have shown that decrease in time intubated is associated with better prognosis. Delirium is associated with increased duration of mechanical ventilation and Intensive Care Unit (ICU) length of stay. However, there is limited report on delirium in intubated seizure patients. As per report, low Glasgow Coma Scale (GCS) increased the risk of delirium and thus increasing ICU length of stay. Information on delirium and outcome in intubated seizure patients receiving lacosamide versus phenytoin is limited. Our re [...]

One way to increase solar photovoltaic penetration in the grid is the management of voltage fluctuations. This is because a photovoltaic plant cannot be interconnected to the grid if it causes voltage violations. Voltage violation is where voltage exceeds the acceptable range. Often, grid operators request photovoltaic plant owners to regulate voltage sufficiently with expensive and space-consuming static Var compensators. Unfortunately, this sometimes makes the project less feasible. This paper argues that there a [...]

The modified Jade Wind-Barrier formula (MJWB) may prevent the common cold in the elderly with a Qi-deficiency Constitution. Previously, no controlled trial evidence existed to illuminate the concept of “preventive treatment of disease” as outlined in the constitution theory of Traditional Chinese Medicine. This theory distinctly suggests that enhancing the Qi-deficiency Constitution and modulating its functional state can prevent the occurrence of the common cold. This controlled trial (ClinicalTrials.gov identifie [...]

Pancreatic islet transplantation holds promise for patients with insulin-dependent diabetes, but is severely limited by a shortage of cadaveric donor islets, and more so because of stringent inclusion criteria for organ donation including donor metabolic function, age, and comorbidities. The impact of these diverse factors on islet health has led to a broad investigation of global influences on islet biology, not least of all, characterization of mature, functional cellular identity and maintenance of appropriate e [...]

Background: Small supernumerary marker chromosomes (sSMC) are rare cytogenetic findings in general, but especially in Turner syndrome so called sSMCT in a karyotype 46, X, +mar are even more scarce. According to the literature, sSMCT are derived from one of the Y-chromosomes in ~70% of the cases. Thus, to identify the presence of Y-chromosomal material is imperative, since these cases have an increased risk of gonadoblastoma deriving from the streak gonads. Methods: A 24-year-old short statured male presented with [...]

Cardiac allograft vasculopathy is one of the leading causes of death following the first 5 years after orthotopic heart transplantation along with late graft failure, likely secondary to undiagnosed CAV. Currently there is no single medical treatment available for this condition except modification of risk factors and immunosuppression. Retrasplantation remains the hope for this entity with some limitations.
