Traditional Chinese medical clinic system

The Chinese Medical Clinic System is designed to help acupuncturists and assistants record and store information. This system can maintain and schedule appointments and view patient diagnoses effectively. The system will be implemented on a desktop PC connected to the internet to facilitate the acupuncturists record of information

The long noncoding RNA, treRNA, decreases DNA damage and is associated with poor response to chemotherapy in chronic lymphocytic leukemia.

The study of long noncoding RNAs (lncRNAs) is an emerging area of cancer research, in part due to their ability to serve as disease biomarkers. However, few studies have investigated lncRNAs in chronic lymphocytic leukemia (CLL). We have identified one particular lncRNA, treRNA, which is overexpressed in CLL B-cells. We measured transcript expression in 144 CLL patient samples and separated samples into high or low expression of treRNA relative to the overall median. We found that high expression of treRNA is significantly associated with shorter time to treatment. High treRNA also correlates with poor prognostic indicators such as unmutated IGHV and high ZAP70 protein expression. We validated these initial findings in samples collected in a clinical trial comparing the nucleoside analog fludarabine alone or in combination with the alkylating agent cyclophosphamide in untreated CLL samples collected prior to starting therapy (E2997). High expression of treRNA was independently prognostic for shorter progression free survival in patients receiving fludarabine plus cyclophosphamide. Given these results, in order to study the role of treRNA in DNA damage response we generated a model cell line system where treRNA was over-expressed in the human B-CLL cell line OSU-CLL. Relative to the vector control line, there was less cell death in OSU-CLL over-expressing treRNA after exposure to fludarabine and mafosfamide, due in part to a reduction in DNA damage. Therefore, we suggest that treRNA is a novel biomarker in CLL associated with aggressive disease and poor response to chemotherapy through enhanced protection against cytotoxic mediated DNA damage

Keragaman Genetik Dan Pendugaan Jumlah Gen Ketahanan Kacang Panjang (Vigna Sinensis L.) Terhadap Penyakit Kuning

Penyakit kuning pada kacang panjang berdampak pada penurunan produksi. Gejala serangan diawali dari gejala daun keriting serta mengakibatkan polong berwarna kuning. Penelitian ini bertujuan mengetahui nilai heritabilitas dan ragam genetik serta menduga jumlah gen pengendali ketahanan kacang panjang terhadap penyakit kuning. Penelitian dilaksanakan di Kabupaten Kediri pada bulan April sampai Juli 2013. Bahan penelitian adalah populasi UB 715 A (P1), Hitam Putih (P2), populasi F1 dan populasi F2. Berdasarkan hasil penelitian, populasi UB 715 A (P1 ) menunjukkan respon tahan terhadap penyakit kuning, populasi Hitam Putih (P2) menunjukkan respon rentan, dan populasi F1 dan F2 menunjukkan respon sedang. Karakter jumlah polong dan jumlah biji per tanaman memiliki keragaman yang sempit sedangkan karakter panjang polong, bobot segar polong, umur berbunga, dan umur panen memiliki keragaman yang luas. Karakter panjang polong dan jumlah biji per polong memiliki nilai heritabilitas rendah, sedangkan karakter jumlah polong, bobot segar polong, umur berbunga, dan umur panen memiliki nilai heritabilitas tinggi. Rasio sifat ketahanan terhadap penyakit kuning pada populasi F2 adalah 9 tahan : 3 sedang : 4 rentan yang berarti ketahanan terhadap penyakit kuning dikendalikan oleh dua gen dengan aksi gen epistasis resesif

Cell-Autonomous Requirement for Rx Function in the Mammalian Retina and Posterior Pituitary

Rx is a paired-like homeobox gene that is required for vertebrate eye formation. Mice lacking Rx function do not develop eyes or the posterior pituitary. To determine whether Rx is required cell autonomously in these tissues, we generated embryonic chimeras consisting of wild type and Rx−/− cells. We found that in the eye, Rx-deficient cells cannot participate in the formation of the neuroretina, retina pigment epithelium and the distal part of the optic stalk. In addition, in the ventral forebrain, Rx function is required cell autonomously for the formation of the posterior pituitary. Interestingly, Rx−/− and wild type cells segregate before the morphogenesis of these two tissues begins. Our observations suggest that Rx function is not only required for the morphogenesis of the retina and posterior pituitary, but also prior to morphogenesis, for the sorting out of cells to form distinct fields of retinal/pituitary cells

Product and Commutativity of k

The commutativity of kth-order slant Toeplitz operators with harmonic polynomial symbols, analytic symbols, and coanalytic symbols is discussed. We show that, on the Lebesgue space and Bergman space, necessary and sufficient conditions for the commutativity of kth-order slant Toeplitz operators are that their symbol functions are linearly dependent. Also, we study the product of two kth-order slant Toeplitz operators and give some necessary and sufficient conditions

Ethanol Extract of the Infructescence of Platycarya strobilacea Sieb. et Zucc. Induces Methuosis of Human Nasopharyngeal Carcinoma Cells

The infructescence of Platycarya strobilacea Sieb. et Zucc. (PS) has been used in the treatment of rhinitis and sinusitis in clinical practice. Our preliminary study showed that an ethanol extract of the infructescence of PS (EPS) had significant antinasopharyngeal carcinoma (NPC) effects in vitro. However, the mechanism underlying the NPS cell death induced by EPS remains unclear. The aim of the present study was to investigate the inhibitory effects of EPS on NPC cells and to elucidate the underlying mechanism. The effects of EPS on NPC cells were investigated in CNE1 and CNE2 cells in vitro. In EPS-treated cells, the cell morphological changes were evaluated through fluorescence microscope, transmission electron microscopy, and flow cytometry. The underlying mechanism was analyzed via network pharmacology and further verified by western blot analysis. The anticancer effects of EPS were associated with the generation of CNE1 and CNE2 cell fusion and vacuoles, the perturbation of lysosomal vesicle transportation, and the induction of methuosis. The network pharmacology and western blot results indicated that the effect of EPS in NPC cells might be achieved via regulation of the Ras proto-oncogene (RAS)/mitogen-activated protein kinase (MAPK) signaling pathway and the transcription factor c-Fos proto-oncogene (c-FOS) and its downstream genes. EPS induces NPC cell death through methuosis. The mechanism might be related to regulation of the transcription factor c-FOS and its downstream genes
