Skin fibroblasts were collected from a 44-year-old patient with sporadic case of Parkinson's disease (PD). The non-integrating Sendai virus vector encoding OCT3/4, SOX2, c-MYC and KLF4 was used to reprogram fibroblasts into induced pluripotent stem cells (iPSCs). Generated iPSCs had normal karyotypes, expressed common stem cell markers, and were capable of differentiating into all three germ layers. Generated line could be used for PD modeling to understand the mechanisms that influence the disorder.

BACKGROUND: The current study used recombinant herpes simplex virus type I to increase expression of µ-opiate receptors and the opioid ligand preproenkephalin in peripheral nerve fibers in a mouse model of neuropathic pain. It was predicted that viral vector delivery of a combination of genes encoding the µ-opioid receptor and preproenkephalin would attenuate neuropathic pain and enhance opioid analgesia. The behavioral effects would be paralleled by changes in response properties of primary afferent neurons...

Despite widespread use of the bacille Calmette-Guérin (BCG) vaccine, tuberculosis (TB) remains a leading cause of global mortality from a single infectious agent (Mycobacterium tuberculosis or Mtb). Here, over two independent Mtb challenge studies, we demonstrate that subcutaneous vaccination of rhesus macaques (RMs) with rhesus cytomegalovirus vectors encoding Mtb antigen inserts (hereafter referred to as RhCMV/TB)-which elicit and maintain highly effector-differentiated, circulating and tissue-resident Mtb-specific CD4+ and CD8+ memory T cell responses-can reduce the overall (pulmonary and extrapulmonary) extent of Mtb infection and disease by 68%, as compared to that in unvaccinated controls, after intrabronchial challenge with the Erdman strain of Mtb at ∼1 year after the first vaccination...

Lymphatic filariasis is a debilitating vector borne parasitic disease that infects human lymphatic system by nematode Brugia malayi. Currently available anti-filarial drugs are effective only on the larval stages of parasite. So far, no effective drugs are available for humans to treat filarial infections. In this regard, aspartate semialdehyde dehydrogenase (ASDase) in lysine biosynthetic pathway from Wolbachia endosymbiont Brugia malayi represents an attractive therapeutic target for the development of novel anti-filarial agents...

Cyclometalated (C^N^C)Au(III) complexes bearing functionalized N-heterocyclic carbene (NHC) ligands provide a high-yielding, modular route to bioconjugated and binuclear complexes. That methodology has been applied to the synthesis of bioconjugated complexes presenting biotin and 17α-ethynylestradiol vectors, as well as to the synthesis of bimetallic Au(III)/Au(I) complexes. The in vitro antiproliferative activities of these compounds against various cancer cells lines depend on the linker length, with the longer linker being the most potent...

Wild birds have repeatedly been highlighted as vectors in the dissemination of livestock and human pathogens. Here, the occurrence, serotypes and antimicrobial resistance of Salmonella were assessed in adult Egyptian vultures (Neophron percnopterus), to test the hypothesis that infection is associated with the consumption of swine carcasses provided at supplementary feeding stations (SFSs). Faeces of year-round resident griffon vultures (Gyps fulvus) were also tested to assess whether infection was acquired in the breeding grounds of both species or in the African wintering quarters of Egyptian vultures...

The prefrontal cortex (PFC) is divided into subregions, including the medial and orbital prefrontal cortices. Dopamine connectivity in the medial PFC (mPFC) continues to be established throughout adolescence as the result of the continuous growth of axons that innervated the nucleus accumbens (NAcc) prior to adolescence. During this period, dopamine axons remain vulnerable to environmental influences, such as drugs used recreationally by humans. The developmental trajectory of the orbital prefrontal dopamine innervation remains almost completely unstudied...

Rett syndrome (RTT) is a severe neurodevelopmental disorder caused by loss-of-function mutations in the gene encoding methyl-CpG-binding protein 2 (MeCP2; Amir et al., 1999), a transcriptional regulatory protein (Klose et al., 2005). Mouse models of RTT (Mecp2 mutants) exhibit excitatory hypoconnectivity in the medial prefrontal cortex (mPFC; Sceniak et al., 2015), a region critical for functions that are abnormal in RTT patients, ranging from learning and memory to regulation of visceral homeostasis (Riga et al...

Projection and backprojection operations are essential in a variety of image reconstruction and physical correction algorithms in CT. The distance-driven (DD) projection and backprojection are widely used for their highly sequential memory access pattern and low arithmetic cost. However, a typical DD implementation has an inner loop that adjusts the calculation depending on the relative position between voxel and detector cell boundaries. The irregularity of the branch behavior makes it inefficient to be implemented on massively parallel computing devices such as graphics processing units (GPUs)...

Timothy J Lang
The seasonal and diurnal cycles of ocean vector winds in the domain of the South China Sea are characterized and compared using RapidScat and the Cross-Calibrated Multi-Platform (CCMP) data sets. Broad agreement in seasonal flow patterns exists between these data sets during the year 2015. Both observe the dramatic reversal from wintertime trade winds (November-April) to westerly flow associated with the summer monsoon (May-October). These seasonal changes have strong but not equivalent effects on mean wind divergence patterns in both data sets...

PURPOSE: One of the major challenges in delivering cytokines for the treatment of hepatocellular carcinoma (HCC) is the mode of delivery. This study hypothesized that genetically engineered bone marrow derived mesenchymal stem cells (BMSCs) co-expressing IFN-γ and IL-10 can serve as a potential therapeutic strategy in the treatment of HCC by inhibiting cell proliferation. METHODS: Male Sprague-Dawley rats (n=5, 200-250 g) for BMSCs isolation and Nude/SCID mice (n=35,12-20g) to develop liver cancer xenograft model were used...

The first report presenting successful and efficient carrot genome editing using CRISPR/Cas9 system. Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR-associated (Cas9) is a powerful genome editing tool that has been widely adopted in model organisms recently, but has not been used in carrot-a model species for in vitro culture studies and an important health-promoting crop grown worldwide. In this study, for the first time, we report application of the CRISPR/Cas9 system for efficient targeted mutagenesis of the carrot genome...

Gene therapy is a clinical tool that may eventually provide therapeutic benefit to patients suffering from movement disorders through a few potential mechanisms: direct correction of the pathogenic mechanism, neuroprotection, neurorestoration or symptom control. The therapeutic mechanism is therefore dependent on knowledge of disease pathogenesis and the required temporal and spatial specificities of gene expression. An additional critical challenge is achieving the most complete transduction of the target structure while avoiding leakage into neighboring regions or perivascular spaces...

Babesia and Theileria are intraerythrocytic protozoans of the phylum Apicomplexa. These species are capable of infecting wild and domestic animals and have historically caused great economic loss in the agricultural industry. In recent years human babesiosis has been deemed an emerging zoonosis in North America, Europe and Asia. The first locally acquired case of babesiosis in Australia, caused by Babesia microti, was reported in March 2012. A number of native Babesia and Theileria species have been identified in Australian marsupials, however their associated tick vectors and threat to human health is unknown...
