Generating thermal energy for temperatures more than 100 degrees centigrade, especially for high capacities, is not easy nor cost efficient. Absorbing chillers with liquid absorber could be used for this application yet there is a limitation for the thermal source which should be in a high temperature. Thus, the desired situation is to use absorbing chillers with least limitations so that the cost for cooling systems would significantly decrease. To this end, we substituted "solid absorbers" instead of liquid absorbers in the absorbing chillers. Beside the advantages of the proposed chillers, e.g. the required temperature for this chiller is low hence the costs would be less, there are some draw backs in implementing the solid absorbers. Hence, the Scientific Air conditioning institute of Iran Technical ＆ Vocation University – Mohajer center, started to work on reducing the absorbing cycle problems. The results of five years researches in this institute came to devising new absorbing chiller using ‘solid absorber’. Main novelties of this system could be mentioned as: the type of the used absorber, the increase of controlling accuracy, efficiency coefficient, the life time, and also the decrease in running time of cycle. In this paper we discuss absorbing chillers with solid absorbers thoroughly. Moreover, the mechanical cycle, thermodynamic cycles and thermodynamic processes are numerically analyzed. We compared our results with the commonly used chillers. The design method, advantages and disadvantages of cycle are illustrated briefly.

Open Journal of Ophthalmology 2014年第3期4卷 100-105页

Yiu Department of Ophthalmology Keck School of Medicine of the Uni-versity of Southern California Los Angeles CA USA Department of Ophthalmology The Wilmer Eye Institute The John Hopkins University Baltimore Maryland USA Doheny Eye Institute Los Angeles CA USA

Purpose: To report a novel Y-suture transfixation technique to improve success rate of high-risk Descemets stripping automated endothelial keratoplasties (DSAEK). Design: Retrospective non-comparative case series. Participants: Twenty five high-risk patients undergoing DSAEK at one tertiary care institution. Methods: A retrospective evaluation of consecutively enrolled high-risk DSAEK cases performed by three surgeons at one institution during a 3-year period (2007-2010). Main outcome measures were graft adherence and suture-related complications. Results: Highrisk factors were defined as followed: prior incisional glaucoma surgery (58%), presence of vitreous in the anterior chamber (15%), anterior chamber intraocular lens (8%), graft dislocation (8%), previous DSAEK (8%), and iris trauma/aphakia (3%). Twenty-five high-risk patients underwent DSAEK with Y-suture transfixation. Postoperative follow-up ranged from 3 to 27 months. One patient had dislocation due to hypotony from prior trabeculectomy (4%), requiring repeat DSAEK. Neither primary graft failure nor suture-related complication was observed. Conclusion: The Y-suture transfixation technique is associated with improved success rate of high-risk DSAEK transplant.

Internal Jugular Vein Graft after Inadvertent Severing of the Internal Carotid Artery during Carotid Endarterectomy and an Urgent Re-Exploration for Immediate Post-Operative Wound Site Bleeding: A Case Report

Open Journal of Modern Neurosurgery 2023年第2期13卷 94-104页

Carotid endarterectomy is a well-established treatment for preventing stroke in selected patients. Although there is debate over whether patch angioplasty or primary closure should be used to reconstruct the bifurcation after carotid endarterectomy, there is growing evidence in the literature in favor of patch angioplasty. When compared to primary closure, patch angioplasty during conventional carotid endarterectomy is suggested to lower the incidence of restenosis and recurrent ipsilateral stroke. Various materials have been used as a patch in this procedure, including the saphenous vein, synthetic patches, or less frequently, an internal jugular vein patch where extensive narrowing of the internal carotid artery is evident. In our case, we used an internal jugular vein graft after inadvertent severing the internal carotid artery (ICA) during carotid endarterectomy after the failure of reconstruction with a saphenous vein patch. We also encountered immediate postoperative reactionary hemorrhage following anesthetic reversal, necessitating an urgent re-exploration. The purpose of this case report is neither an attempt to suggest all patients need angioplasty nor to state that an internal jugular vein patch or graft is superior to synthetic material or saphenous veins;rather, it is an attempt to emphasize a potentially effective rescue way to reconstruct inadvertent extensive vascular injury during carotid endarterectomy.

The prevalence of coronary artery disease (CAD) is increasing in Iran. Patients with depression who have a myocardial infarction are more likely to die and patients who have depressive symptoms during hospitalization may have increased cardiovascular events. This study aimed to determine the relationship between anxiety, depression and coronary artery disease among patients undergoing angiography in Ghaem Hospital, Mashhad. This was a case-control study conducted between September 2011 and August 2012 among patients undergoing coronary angiography in Ghaem Hospital, Mashhad, Iran. There were 486 cases that were found to have one or more coronary stenoses, with a stenosis of equal or more than 50% of the diameter of at least one major coronary artery. The other patient group consisted of the patients in whom the coronary artery stenosis was less than 50% in diameter which was classified as angiography negative, and a control group that consisted of 440 healthy adults aged 18 years old and above who were selected among people who attended for routine medical checkup and medical examination of employment. The dependent variables were Beck Anxiety and Depression Inventory scores and the independent factors were coronary artery disease, and socioeconomic profiles. Validated and reliability-tested questionnaires were used for data collection. The mean age of patients was 55.75 ± 10.64 years and in the healthy group was 55.83 ± 8.55 years;there was no significant difference in age between subject groups (p = 0.897) nor a significant difference in the gender frequency distribution of subjects (p = 0.610). There was a significant difference in anxiety score between the Angio positive and Angio negative patients and healthy control subjects

AIM: To describe our experience using a low-acceleratingdose regimen(LADR) with pegylated interferon alpha-2a and ribavirin in treatment of hepatitis C virus(HCV) recurrence. METHODS: From 2003, a protocolized LADR strategy was employed to treat liver transplant(LT) recipients with recurrent HCV at our institution. Medical records of 182 adult patients with recurrent HCV treated with LADR between 1/2003 and 1/2011 were reviewed. Histopathology from all post-LT liver biopsies were reviewed in a blinded fashion. Paired recipient and donor IL28 B status were assessed. A novel technique was employed to ascertain recipient and donor IL28B(rs12979860) Gt data using DNA extracted from archival FFPE tissue from explanted native livers and donor gallbladders respectively. The primary endpoint was SVR; secondary endpoints examined include(1) patient and graft survival;(2) effect of anti-viral therapy on liver histology(fibrosis and inflammation);(3) incidence of on-treatment development of ACR, CDR, or PCH;(4) association of recipient and donor IL28 B genotype with SVR; and(5) incidence of antiviral therapy-associated adverse events(anemia, leukopenia, thrombocytopenia, depression) and hepatic ***: The overall SVR rate was 38%(29% Gt1, 67% Gt2, 86% Gt3 and 58% Gt4). HCV Gt(P nor age(P = 0.003), cytomegalovirus mismatch(P = 0.001), baseline serum bilirubin(P = 0.002), and baseline viral load(P = 0.04) were independent predictors for SVR. SVR rates were significantly higher in the recipient-CC/donor-non CC pairs(P = 0.007). Neither baseline fibrosis nor change in fibrosis stage after anti-viral therapy were associated with SVR. Fibrosis progressed in 72% of patients despite SVR. Median graft survival was 91 mo. Five-year patient survival was superior in patients who achieved SVR(97% vs 82%, P = 0.001). Pre-treatment ALP ≥ 150 U/L(P = 0.01), total bilirubin ≥ 1.5 mg/d L(P = 0.001) and creatinine ≥ 2 mg/d L(P = 0.001) were independently associated
