BACKGROUND: Intrathecal drug delivery is an attractive option to circumvent the blood-brain barrier for pain management through its increased efficacy of pain relief, reduction in adverse side effects, and cost-effectiveness. Unfortunately, there are limited guidelines for physicians to choose infusion or drug pump settings to administer therapeutic doses to specific regions of the spine or the brain. Although empiric trialing of intrathecal drugs is critical to determine the sustained side effects, currently there is no inexpensive in vitro method to guide the selection of spinal drug delivery parameters...

Mutations in SOX10 cause neurocristopathies which display varying degrees of hypopigmentation. Using a sensitized mutagenesis screen, we identified Smarca4 as a modifier gene that exacerbates the phenotypic severity of Sox10 haplo-insufficient mice. Conditional deletion of Smarca4 in SOX10 expressing cells resulted in reduced numbers of cranial and ventral trunk melanoblasts. To define the requirement for the Smarca4 -encoded BRG1 subunit of the SWI/SNF chromatin remodeling complex, we employed in vitro models of melanocyte differentiation in which induction of melanocyte-specific gene expression is closely linked to chromatin alterations...

Rapid eye movement sleep (REMS) plays important role in maintenance of normal brain functions. Neurons containing various neurotransmitters in different brain regions interact to regulate this complex phenomenon in health and diseases. The number of neuronal projections, their firing rates and neurotransmitter levels vary in different brain regions under various conditions leading to normal or altered patho-physio-behavioral states. In this study using high performance liquid chromatography (HPLC) we quantified noradrenaline (NA) and gamma-amino butyric acid (GABA) levels in locus coeruleus (LC), dorsal raphe (DR), pedunculo-pontine tegmentum (PPT), frontal lobe (FL), cortex and hippocampus (Hippo) in control and after 96h REMS deprivation (REMSD) rats...

BACKGROUND: Practice guidelines have been developed for early-stage and locally advanced non-small cell lung cancer (NSCLC). However, many common clinical scenarios still require individualized decision making. This is true for locoregional relapse after initial stereotactic radiotherapy (stereotactic body radiation therapy or stereotactic ablative radiotherapy; SBRT or SABR), an increasingly utilized curative treatment option for stage I NSCLC. METHODS: A consortium of expert radiation oncologists was established with the aim of providing treatment recommendations...

Penile squamous cell carcinoma (PSCC) is an orphan malignancy with poorly understood biology and suboptimal systemic therapy. Given that kinases may be drivers and readily actionable, we performed comprehensive multiplatform analysis of kinases in PSCC tumor and normal tissue. Fresh frozen tumors were collected from 11 patients with PSCC. After macrodissection to demarcate tumor from normal tissue, the samples underwent multiplatform analysis of kinases. Next Generation Sequencing (NGS) of 517 kinase genes was performed using Agilent Kinome capture and run on the Illumina MiSeq at PE150bp...

Residual host cell proteins (HCPs) are process-related impurities present in biotherapeutics that can pose safety health risks to patients. An adequate control of HCP levels in the final product, and demonstration of HCP clearance throughout a product manufacturing process is critical for all biotherapeutic products. Developing effective downstream purification processes can be challenging as HCPs and product proteins may possess an affinity for each other or have similar physicochemical properties, resulting in co-purification...

Polymorphonuclear myeloid-derived suppressor cells (PMN-MDSC) are important regulators of immune responses in cancer and have been directly implicated in promotion of tumor progression. However, the heterogeneity of these cells and lack of distinct markers hampers the progress in understanding of the biology and clinical importance of these cells. Using partial enrichment of PMN-MDSC with gradient centrifugation we determined that low density PMN-MDSC and high density neutrophils from the same cancer patients had a distinct gene profile...

The brachial plexus innervates the upper extremities. While variations in the formation of the brachial plexus and its terminal branches are quite common, it is uncommon for the median nerve to innervate the muscles of the arm. During the dissection of an elderly male cadaver at the Department of Anatomy, All India Institute of Medical Sciences, New Delhi, India, in 2016, the coracobrachialis muscle was found to be supplied by a direct branch from the lateral root of the median nerve and the musculocutaneous nerve was absent...
