The non-coding displacement (D) loop of the human mitochondrial (mt) genome contains two hypervariable regions known as HVR1 and HVR2 that are most often analyzed by forensic DNA laboratories. The massively parallel sequencing (MPS) protocol from Illumina (Human mtDNA D-Loop Hypervariable Region protocol) utilizes four sets of established PCR primer pairs for the initial amplification (enrichment) step that span the hypervariable regions. Transposase adapted (TA) sequences are attached to the 5'-end of each primer, allowing for effective library preparation prior to analysis on the MiSeq, and AmpliTaq Gold DNA polymerase is the enzyme recommended for amplification...

OBJECTIVE: Mitochondrial dysfunction plays a key role in the pathophysiology of neurodegenerative disorders such as ataxia and Parkinson's disease. We describe an extended Belgian pedigree where seven individuals presented with adult-onset cerebellar ataxia, axonal peripheral ataxic neuropathy, and tremor, in variable combination with parkinsonism, seizures, cognitive decline, and ophthalmoplegia. We sought to identify the underlying molecular etiology and characterize the mitochondrial pathophysiology of this neurological syndrome...

Aircrew members can be exposed to higher annual doses of natural ionizing radiation than members of the general population in most parts of the world. The principal ionizing radiation to which they are exposed is galactic cosmic radiation (GCR). Among the particles present in the primary spectrum are heavy ions: relativistic nuclei of lithium and heavier elements. These ions have very high radiation weighting factors and can contribute significantly to the effective dose at altitudes above the Pfotzer maximum...

Precise duplication of the genome is a prerequisite for the health and longevity of multicellular organisms. The temporal regulation of origin specification, replication licensing, and firing at replication origins is mediated by the cyclin-dependent kinases. Here the role of Cip1 interacting Zinc finger protein 1 (Ciz1) in regulation of cell cycle progression is discussed. Ciz1 contributes to regulation of the G1/S transition in mammalian cells. Ciz1 contacts the pre-replication complex (pre-RC) through cell division cycle 6 (Cdc6) interactions and aids localization of cyclin A- cyclin-dependent kinase 2 (CDK2) activity to chromatin and the nuclear matrix during initiation of DNA replication...

: Chronic use (>90 Days) of opioid analgesics significantly increases the risk of development of new depression episodes (NDE). It is unclear whether depression that develops in this manner is similar to or different from NDE in persons not exposed to opioid analgesic use (OAU). METHODS: VA patients were classified into two groups, those who did not receive an opioid and developed depression (non-OAU+NDE, n=4314) and those that had >90 days OAU and developed NDE (OAU+NDE, n=444)...

BACKGROUND: Donor specific antibodies (DSAs) after lung transplantation correlate with poor outcomes. The ideal treatment strategy for antibody mediated rejection AMR is not defined. Our institution implemented an aggressive multi-modality protocol for the treatment of suspected AMR. METHODS: Lung transplant recipients with suspected AMR were treated with a standardized protocol of plasma exchange, steroids, bortezomib, rituximab, and intravenous immune globulin...

Sima del Elefante, Atapuerca, Spain contains one of the earliest hominin fragments yet known in Europe, dating to 1.2 Ma. Dental calculus from a hominin molar was removed, degraded and analysed to recover entrapped remains. Evidence for plant use at this time is very limited and this study has revealed the earliest direct evidence for foods consumed in the genus Homo. This comprises starchy carbohydrates from two plants, including a species of grass from the Triticeae or Bromideae tribe, meat and plant fibres...

To evaluate social development of pediatric heart transplant (tx) recipients who have lived 15 or more years after transplantation. Among 498 pediatric patients, age less than 18 years, who underwent heart transplantation, at a single institution, 337 were performed between 1985 and 1998. We identified all who survived more than 15 years and engaged them in a survey regarding employment, education, marital, and social status. One hundred and eighty-three recipients (54.3%; 183/337) have survived greater than 15 years; of these, 150 (81...

BACKGROUND: Low serum testosterone (low T) has been repeatedly linked to worse outcomes in men with newly diagnosed prostate cancer (PC). How low T contributes to these outcomes is unknown. Here we demonstrate that exposure to low T causes significant changes in the mouse prostate and prostate stem cells. METHODS: Mice were castrated and implanted with capsules to achieve castrate, normal, or sub-physiological levels of T. After 6 weeks of treatment, LC-MS/MS was used to quantify the levels of T and dihydrotestosterone (DHT) in serum and prostate tissue...

Caveolin-1 (Cav1) drives the formation of flask-shaped membrane invaginations known as caveolae that participate in signaling, clathrin-independent endocytosis and mechanotransduction. Overexpression or mutations of Cav1 can lead to its mistrafficking, including its accumulation in a perinuclear compartment previously identified as the Golgi complex. Here, we show that in the case of overexpressed Cav1-GFP, this perinuclear compartment consists of cytoplasmic inclusion bodies generated in response to the accumulation of aggregates of misfolded proteins, known as aggresomes...

We describe a symmetron model in which the screening of fifth forces arises at the one-loop level through the Coleman-Weinberg mechanism of spontaneous symmetry breaking. We show that such a theory can avoid current constraints on the existence of fifth forces but still has the potential to give rise to observable deviations from general relativity, which could be seen in cold atom experiments.

BACKGROUND: Colorectal cancer (CRC) remains the most commonly diagnosed cancer among Korean Americans (KAs) in part due to low screening rates. Recent studies suggest that some KA patients engage in medical tourism and receive medical care in their home country. The impact of medical tourism on CRC screening is unknown. The purpose of this paper was to 1) investigate the frequency of medical tourism, 2) examine the association between medical tourism and CRC screening, and 3) characterize KA patients who engage in medical tourism...

BACKGROUND: Physical activity (PA) levels are lower among some UK Black and minority ethnic (BME) groups than the majority White British population and a variety of tailored interventions have emerged. This study documents the characteristics and logic of local adaptations, a vital first step in evaluating such innovations. METHODS: An English PA data set was examined to identify and characterize PA programmes focussed on BME populations. Three case studies were conducted, employing documentary analysis and qualitative interviews...

OBJECTIVE: To define clinical features of surgical patients in whom postoperative blood cultures are likely to identify pathogens. BACKGROUND: Bacteremia is a worrisome postoperative complication and blood cultures (BCx) are routinely used for evaluation of postoperative bacteremia, but are costly and not always diagnostic. Better methods are needed to select patients in whom BCx identify pathogens. METHODS: We reviewed records of patients ≥18 years old with BCx drawn ≤10 days after surgery in 2013 seeking independent predictors of positive cultures by simple and multiple logistic regression models with statistical significance at α = 0...
