Mohammad Javad Alemzadeh‐Ansari Ali Sarreshtehdari Seifollah Abdi Jamal Moosavi Omid Shafe Parham Sadeghipour Hamidreza Pouraliakbar Bahram Mohebbi 《Seminars in dialysis》2021,34(1):89-93
A 70‐year‐old man with a history of coronary artery bypass grafting 15 years back and arteriovenous (AV) fistula creation in the left arm 1 month back presented with acute coronary syndrome (ACS). He had not received dialysis before his referral. We felt the most likely etiology for these complaints was increased cardiac oxygen demand from an increased cardiac output related to the newly formed left AV fistula. Coronary angiography was done to detect any significant stenosis in the native or grafted vessels. This revealed that the left subclavian artery was totally occluded in the ostioproximal segment and the coronary arteries did not have occlusions to explain the ACS setting. CT angiography confirmed the angiographic findings of the totally occluded left subclavian artery followed by a well‐developed and patent left internal mammary artery to left anterior descending artery. This led to the consideration of a steal syndrome from the coronary artery by the subclavian artery distal to the occlusion. A successful percutaneous endovascular intervention on the left subclavian artery occlusion was performed. Subsequently, the patient became asymptomatic and experienced a dramatic increase in left ventricular ejection fraction. 相似文献

Combining work and care can be very challenging. If not adequately supported, carers’ employment, well-being and relationships may be at risk. Technologies can be potential solutions. We carried out a scoping review to find out what is already known about technologies used by working carers. The search included academic and grey literature published between January 2000 and June 2020. Sixteen relevant publications were analysed and discussed in the context of the broader discourse on work-care reconciliation. Technologies discussed can be classified as: (a) web-based technologies; (b) technologies for direct communication; (c) monitoring technologies; and (d) task-sharing tools. Technologies can help to make work-care reconciliation more manageable and alleviate psychosocial and emotional stress. General barriers to using technology include limited digital skills, depending on others to use technologies, privacy and data protection, cost, limited technological capabilities, and limited awareness regarding available technologies. Barriers specific to some technologies include work disruptions, limited perceived usefulness, and lacking time and energy to use technologies. More research into technologies that can address the needs of working carers and how they are able to use them at work is needed. 相似文献

The main aim of this study was to assay the testicular H2S levels in the varicocele rat model and then to investigate the protective effects of NaHS on morphometric changes, sperm parameters, oxidative stress and apoptosis markers in rat's testis. D,L-propargylglycine (PAG) was administrated to show the effects of cystathionine γ-lyase enzyme (CSE) inhibition in the varicocele. Rats were assigned to four groups: (a) Sham, (b) varicocele, (c) varicocele + PAG and (d) varicocele + NaHS. Animals in varicocele + NaHS group received 30 µmol/L NaHS in drinking water for 56 days. In the varicocele + PAG group, animals received PAG 19 mg/kg twice a week. Morphometric assessment, oxidative stress markers, testicular H2S levels, sperm parameters, TUNEL assay and expression of Bax/Bcl2 were evaluated at the end of experiment. Testicular H2S levels were significantly decreased in varicocele group. NaHS significantly improved sperm parameters, morphometric characteristics and oxidative stress compared to varicocele group. Oxidative stress status deteriorated in the PAG group compared to the varicocele group. This study showed that a low testicular H2S level might play a critical role in male infertility. Thus, NaHS administration may be a promising treatment strategy for male infertility in varicocele. In addition, CSE may not be the only important enzyme in testicular H2S production. 相似文献

Objective
The use of preparations based on minerals extracts of Calicotome villosa and butter is born from the misuse of drugs without specific microbiological analyzes. Seventeen different preparations were performed. The antibacterial and antifungal activities were determined on five bacteria and two fungi strains respectively.Material and methods
C.villosa ashes are obtained by incineration of roots plant at 498 °C for 4 hours. They are analyzed to determine the shape of the particles and the mineral constituents by scanning electronic microscopy (SEM) and energy dispersive X-ray spectrometry (EDX) techniques respectively. The effectiveness of preparations or tablets is measured in solid medium. It allows to calculating the diameter of the inhibition zone for the antibacterial activity as well as the diameter of mycelia growth and the critical values (MIC, MFC, IC50 and IC90) for the antifungal activity. Finally, the results are compared to the activity of a commercial positive control aiming to give value of the observed activity.Results
SEM observations reveal the presence of nanoparticles agglomerated with size of about 50 nm. The EDX analyzes indicate the presence of Fe, Na, Al, Mg, Si, K, Ca, O2 and C. Among all the results, the preparation (Bs + A) or (Bsd + A) can completely inhibit the growth of two fungal pathogens. The activity of the preparation is faced with the activity of the synthetic fungicide nystatin.Conclusion
The efficacy of the preparation (Bs + A) or (Bsd + A) is larger than that of nystatin against Aspergillus sp. and Fusarium sp. The preparation could serve as natural antifungal for the pharmaceutical industry. 相似文献9.

Ten patients with advanced cancer were treated with weekly intravenous escalating doses of human beta-interferon (HuIFN beta) 4 days each week. The starting dose of HuIFN beta was 3.0 X 10(6) units/m2 and the dose was doubled each week until dose-limiting toxicity was observed. Subjective toxicity included mild fevers and chills, malaise and flu-like symptoms. The lowest dose which caused suppression of the platelet and/or white cell count was 64 X 10(6) units daily, and the maximum dose given was 320 X 10(6) units daily. Both subjective and objective toxicity were not dose-related, easily managed and reversible. Serum interferon levels and the duration of measurable interferon activity on natural killer cells was in general dose-dependent. Two patients had an objective partial response, and two others showed stable disease while receiving HuIFN beta. 相似文献
