Brief exposure of the heart to hypoxia results in less cellular damage after subsequent hypoxia, an effect known as preconditioning (PC). PC has been widely studied but is still not fully understood. Adenosine (Ado), adenosine receptors, and protein kinase C (PKC) have been implicated as integral components of PC. Adenosine (nucleoside) transporters (NTs) facilitate flux of Ado across cell membranes, but their role in PC is unknown. Therefore, we used the murine cardiomyocyte cell line, HL-1, and asked if there was feedback regulation of NTs by Ado, Ado receptors, and PKC following either hypoxic or pharmacological PC. Activation (by specific agonists) of A1 or A3 Ado receptors or PKC resulted in PC in HL-1. The A1 (but not A3) receptor is coupled to PKCepsilon, and activation of PKCepsilon (by specific peptide agonist) resulted in PC. Moreover, PKCepsilon stimulates Ado uptake via the predominant NT in HL-1, mouse equilibrative nucleoside transporter 1 (mENT1). Studies in primary neonatal mouse cardiomyocytes confirmed our observations in HL-1 cells. Hypoxic challenge led to a rapid increase in, and efflux of, intracellular Ado from cells, which was blocked by NT inhibitors (dipyridamole/nitrobenzylthioinosine). Moreover, NT inhibition during hypoxia or PC was highly protective, suggesting that Ado loss contributes to decreased cell viability. Our data suggest that hypoxic challenge causes an efflux of Ado via ENTs, activation of A1 and/or A3 receptors, signaling through PKCepsilon, and activation of ENT1. Since Ado is required for ATP synthesis on reperfusion, this feedback regulation of mENT1 would promote reuptake of Ado. 相似文献

To determine the growth pattern and in vitro susceptibility of Blastocystis hominis to metronidazole (MTZ), garlic, ginger, white cumin, and black pepper. Stool specimens were collected from 16 irritable bowel
syndrome (IBS) and 10 controls between July–November 2010. Stool microscopy and culture for B. hominis was performed. Drug susceptibility assays was done using 0.01 and 0.1 mg/ml of MTZ, garlic, ginger, white cumin, and black
pepper. Effect was assessed on B. hominis culture after 48 h. Stool DNA was extracted using stool DNA extraction kit (Qiagen) and polymerase chain reaction (PCR) done
using subtype-specific sequence-tagged-site primers. B. hominis genotype 3 and coinfection of 1 and 3 tended to grow well in culture compared to isolated type 1 infection. Exposed to MTZ
at a concentration of 0.01 mg/ml, 38% (6/16) B. hominis from IBS did not grow in culture compared to 100% (10/10) of B. hominis from control (p = 0.001). When they were exposed to MTZ at 0.1 mg/ml, 56% (9/16) B. hominis from IBS did not grow in cultures compared to 100% (10/10) from control (p = 0.01). Forty-four percent (7/16) B. hominis from IBS did not grow in culture compared to 100% (10/10) B. hominis from control when exposed to garlic at a concentration of 0.01 mg/ml (p = 0.003) and following exposure to garlic at 0.1 mg/ml, 38% (6/16) B. hominis from IBS did not grow in cultures compared to 100% (10/10) from control (p = 0.001). B. hominis isolates from IBS had a cell count of 6,625 at a MTZ concentration of 0.01 mg/ml that reduced to 1,250 as MTZ concentration
was increased to 0.1 mg/ml (p = 0.08). B. hominis from IBS with a mean cell count of 3 × 105 at baseline decreased to 1 × 104 when exposed to garlic at 0.01 mg/ml (p < 0.001) and to 1 × 103 (p < 0.001) when garlic was 0.1 mg/ml. B. hominis from IBS cell count decreased to 1 × 105 when exposed to white cumin at 0.01 mg/ml (p = 0.01) and to 1 × 105 (p < 0.001) when white cumin was 0.1 mg/ml. Exposed to black pepper at 0.1 mg/ml, cell count of B. hominis from IBS decreased to 1 × 105 (p = 0.01). B. hominis from IBS decreased to 1.3 × 105 exposed to ginger at 0.01 mg/ml (p = 0.001). B. hominis isolates were mostly genotypes 3, type 1 and 3 coinfection, and non-typeable B. hominis isolates. B. hominis isolates from IBS mostly genotype 1 demonstrated an increased sensitivity to garlic at 0.01 mg/ml with a B. hominis cell count of 3,714 compared to 6,142 when exposed to 0.01 mg/ml of MTZ. However, this sensitivity did not increase as garlic
concentration was increased to 0.1 mg/ml, for B. hominis cell count was 6,000 compared to 1,428 as MTZ was increased to 0.1 mg/ml. 相似文献

Weight gain is a well-known and unwanted complication of adjuvant chemotherapy in breast cancer. We observed that the female
Turkish cancer patients frequently gain weight with adjuvant treatment of breast cancer and planned to examine the magnitude
of this problem in early breast cancer patients treated at our hospital. A total of 176 early breast cancer patients who received
their adjuvant systemic therapy in Marmara University Hospital between 2003 and 2007 are included in the study. We recorded
their weight before and after chemotherapy and also a year after chemotherapy to find out whether the change with weight is
transitory. We have also recorded demographic information, including the educational level, menopausal status, the type of
chemotherapy or hormonal treatment administered stage of disease, marital status, occupation and the underlying diseases to
analyze the relationship between change in weight and these parameters. Median age of patients was 53 and 72% of patients
were postmenopausal. Educational level was equally distributed for primary education (27%), high school (40%), and university
(33%). The majority of the patients (76%) was married, had two children (69%) and was housewife (60%). Family history of any
cancer was high (32%). Most of the patients had stage II cancer (56%), received anthracyclines+/− taxane based chemotherapy
(98%) and had no underlying disease (68%). The majority also did not smoke (73%) or drink alcohol (93%). A total of 67% and
72% patients gained weight upon completion and one year after completion of chemotherapy. Mean weight before the chemotherapy,
upon completion of chemotherapy and one year after completion of chemotherapy were 68.9 kg, 70.6 kg (P = 0.000) and 71.9 kg (P = 0.000) respectively. Mean body mass index was 27.1 at baseline, 27.8 upon completion of chemotherapy (P = 0.000) and 28.3 one year after completion of chemotherapy (P = 0.000). Age, menopausal status, multiparity and presence of comorbid diseases had statistically significant impact on weight
gain following adjuvant therapy in breast cancer patients (P = 0.000, P = 0.008, P = 0.015 and P = 0.017 respectively). This study shows that Turkish women with early breast cancer gain weight after adjuvant systemic therapy,
in line with European and American counterparts. This increase in weight is maintained at least one year after adjuvant therapy.
Given the adverse consequences of weight gain in terms of both breast cancer prognosis and general health, it is necessary
to inform patients about this change and to develop strategies for weight maintenance during and after systemic therapy. 相似文献

Efficient homologous recombination permits the directed introduction of specific mutations into the yeast genome. Here we describe a cloning-free, PCR-based allele replacement method that simplifies allele transfer between yeast strains. The desired allele from one strain is amplified by PCR, along with a selectable/counterselectable marker. After transformation, the resident allele in the target strain is replaced by creating a duplication of the new allele. Selection for direct repeat recombinants results in a single copy of the new allele in the target strain. Specifically, the desired allele is amplified by PCR with a pair of adaptamers, which are chimeric oligonucleotides that are used to amplify the allele and differentially tag its 5′ and 3′ ends. These tags allow the directed fusion to two different, but overlapping, regions of an appropriately tagged selectable/counterselectable marker after a second round of PCR amplification. Following cotransformation of the two fusion fragments into yeast, homologous recombination efficiently generates a duplication of the amplified allele flanking the intact selectable marker in the genome. After counterselection, only the desired allele is retained as a result of direct repeat recombination. A simple modification of this method allows the creation of de novo mutations in the genome. 相似文献

2,6-Bis(benzimidazol-2-yl)pyridine (L) ligand and complexes [M(L)Cl(2)] and [Fe(L)(2)](ClO(4))(2) (M=Zn, Cd, Hg) have been synthesized. The geometries of the [M(L)Cl(2)] complexes were derived from theoretical calculation in DGauss/DFT level (DZVP basis set) on CACHE. The central M(II) ion is penta-coordinated and surrounded by N(3)Cl(2) environment, adopting a distorted trigonal bipyramidal geometry. The ligand is tridentate, via three nitrogen atoms to metal centre and two chloride ions lie on each side of the distorted benzimidazole ring. In the [Fe(L)(2)](ClO(4))(2) complex, the central Fe(II) ion is surrounded by two (3N) units, adopting a octahedral geometry. The elemental analysis, molecular conductivity, FT-Raman, FT-IR (mid-, far-IR), (1)H, and (13)C NMR were reported. The antimicrobial activities of the free ligand, its hydrochloride salt, and the complexes were evaluated using the disk diffusion method in dimethyl sulfoxide (DMSO) as well as the minimal inhibitory concentration (MIC) dilution method, against 10 bacteria and the results compared with that for gentamycin. Antifungal activities were reported for Candida albicans, Kluyveromyces fragilis, Rhodotorula rubra, Debaryomyces hansenii, Hanseniaspora guilliermondii, and the results were referenced against nystatin, ketaconazole, and clotrimazole antifungal agents. In most cases, the compounds tested showed broad-spectrum (Gram positive and Gram negative bacteria) activities that were either more effective than or as potent as the references. The binding of two most biologically effective compounds of zinc and mercury to calf thymus DNA has also been investigated by absorption spectra. 相似文献
