BACKGROUND The polycomb group (PcG) protein BMI1 is an important regulator of development. Additionally, aberrant expression of BMI1 has been linked to cancer stem cell phenotype and oncogenesis. In particular, its overexpression has been found in several human malignancies including breast cancer. Despite its established role in stem cell maintenance,(More)
Glioblastoma is one of the most aggressive forms of primary brain tumors of glial cells, including aberrant regulation of glycogen synthase kinase 3 β (GSK3 β ) and splicing factors deregulation. Here, we investigate the role of small molecule AR-A014418 and Manzamine A against GSK3 kinase with factual control on splicing regulators. AR-A 014418, 48 hrs(More)
BACKGROUND Mineral Pitch (MP) is a dark brown coloured humic matter originating from high altitude rocks. It is an Ayurvedic medicinal food, commonly used by the people of the Himalayan regions of Nepal and India for various body ailments. METHODS The Huh-7 cells were treated with different concentrations of MP for 24 h, and both apoptosis and(More)
Single-crystalline thin films of complex oxides show a rich variety of functional properties such as ferroelectricity, piezoelectricity, ferro and antiferromagnetism and so on that have the potential for completely new electronic applications. Direct synthesis of such oxides on silicon remains challenging because of the fundamental crystal chemistry and(More)
Hepatitis B Virus (HBV) utilizes several mechanisms to survive in the host cells and one of the main pathways being autophagosome formation. Humic acid (HA), one of the major components of Mineral pitch, is an Ayurvedic medicinal food, commonly used by the people of the Himalayan regions of Nepal and India for various body ailments. We hypothesized that HA(More)
Foreign body ingestion is seen quite frequently in clinical practice, intestinal perforation due to this is rare. The foreign body often mimics another cause of acute abdomen and requires an emergency surgical intervention. The majority of patients do not recall ingesting sharp foreign bodies. We report an interesting case of a fifty five year-old man who(More)
BACKGROUND While diarrhoea is the second major killer among the under-five children in the world with an estimation of 760,000 deaths annually, it stands as a major killer in Nepal with an annual incidence of 500 per 1000 under-five children with diarrhoea. Diarrhoea is responsible for a wide range of morbidity and mortality among children in Nepal. The(More)
Of several subtypes of breast cancer, triple negative breast cancer (TNBC) is a highly aggressive tumor that lacks expression of hormone receptors for estrogen, progesterone and human epidermal growth factor receptor 2 and shows a worst prognosis. The small noncoding RNAs (miRNAs) considered as master regulator of gene expression play a key role in cancer(More)
Resistance to drugs, which is aggravated by hypoxia, is a well-known feature of tumors. The combination of drug exposure and hypoxia can give rise to several survival strategies in the exposed cells. Glioblastoma multiforme (GBM) is among the most hypoxic of solid tumors, and we have used glial cells to identify a drug combination that would be(More)
The main purpose of this pictorial review is to highlight the important MR imaging findings of various conditions involving the cavernous sinus in addition to brief description of normal anatomy. The pathological conditions that can involve the cavernous sinus can be categorized into infective, inflammatory, granulomatous, vascular and neoplastic causes.(More)
