Background: The high prevalence of transfusion-transmitted infections (TTIs) is causing serious harm to human health worldwide. The aim of this research was to assess the prevalence and influencing factors of TTIs in Southwest China. Methods: A retrospective study of blood donor records from January 2008 to December 2015 was conducted. All samples were screened for HBV, HCV, HIV and syphilis. The donor's data was recorded and analyzed statistically using SPSS software...

The record of the Millennium Development Goals broadly reflects the trade-offs of disease-specific financing: substantial progress in particular areas, facilitated by time-bound targets that are easy to measure and communicate, which shifted attention and resources away from other areas, masked inequalities and exacerbated fragmentation. In many ways, the Sustainable Development Goals reflect a profound shift towards a more holistic, system-wide approach. To inform responses to this shift, this article builds upon existing work on aggregate trends in donor financing, bringing together what have largely been disparate analyses of sector-wide and disease-specific financing approaches...

In pulmonary fibrosis (PF), fibroblasts and myofibroblasts proliferate and deposit excessive extracellular matrix in the interstitium, impairing normal lung function. As most forms of PF have a poor prognosis and limited treatment options, PF represents an urgent unmet need for novel, effective therapeutics. While the role of immune cells in lung fibrosis is unclear, recent studies suggest that T lymphocyte (T cell) activation may be impaired in PF patients. Further, we have previously shown that activated T cells can produce prostaglandins with anti-scarring potential...

Application of H2S ('sulfide') elicits a complex contraction in rat pulmonary arteries (PA) comprising a small transient contraction (phase 1; Ph1) followed by relaxation and then a second, larger, and more sustained contraction (phase 2; Ph2). We investigated the mechanisms causing this response using isometric myography in rat second order PA, with Na2S as a sulfide donor. Both phases of contraction to 1000μM Na2S were attenuated by the pan-PKC inhibitor Gö6983 (3μM) and by 50μM ryanodine; the Ca2+ channel blocker nifedipine (1μM) was without effect...

BACKGROUND: Ischemic type biliary lesions arise most frequently after DCD liver transplantation and result in high morbidity and graft loss. Many DCD grafts are discarded out of fear for this complication. In theory, microvascular thrombi deposited during donor warm ischemia might be implicated in ITBL pathogenesis. Herein, we aim to evaluate the effects of the administration of either heparin or the fibrinolytic drug TPA as means to improve DCD liver graft quality and potentially avoid ITBL...

Despite advances in the practice of live donor liver transplantation (LDLT), the optimum surgical approach with respect to the middle hepatic vein (MHV) in right lobe LDLT remains undefined. We designed a randomized trial to compare the early postoperative outcomes in recipients and donors between extended right lobe grafts (ERG: transection plane was maintained to the left of MHV, and division of MHV performed beyond the segment VIII vein) and modified right lobe grafts (MRG: transection plane was maintained to the right of MHV, the segment V and VIII drainage was reconstructed using a conduit of recipient portal vein)...

Hepatic ischemia-reperfusion injury (IRI) represents a major risk factor of early graft dysfunction and acute/chronic rejection as well as a key obstacle to expanding the donor pool in orthotopic liver transplantation (OLT). Although glucocorticoid receptor (GR) signaling may enhance cytoprotective programs, clinical use of glucocorticoid is limited due to adverse effects, while clinical relevance of GR-facilitated cytoprotection in OLT remains unknown. We aimed to evaluate the significance of hepatic GR in clinical OLT and verify the impact of recombinant human relaxin (rhRLX), which may function as GR agonist in tissue/disease-specific manner...

A bis-crown ether-oxoporphyrinogen was newly synthesized and self-assembled concurrently with C60 alkyl ammonium cations at the crown ether sites and F- anions (through hydrogen bonding) at the oxoporphyrinogen core. Ultrafast photoinduced charge transfer processes within the donor-acceptor conjugate were promoted by fluoride ion binding and this was established using various spectroscopic methods and transient absorption studies.

PURPOSE: Saliva is an attractive sample source for the biomarker-based testing of several diseases, especially oral cancer. Here, we sought to apply multiplexed LC-MRM-MS to precisely quantify 90 disease-related proteins and assess their intra- and inter-individual variability in saliva samples from healthy donors. EXPERIMENTAL DESIGN: We developed two multiplexed LC-MRM-MS assays for 122 surrogate peptides representing a set of disease-related proteins. Saliva samples were collected from 10 healthy volunteers at three different time points (Day 1 morning and afternoon, and Day 2 morning)...

BACKGROUND: Emerging transfusion-transmissible pathogens, including arboviruses such as West Nile, Zika, dengue, and Ross River viruses, are potential threats to transfusion safety. The most prevalent arbovirus in humans in Australia is Ross River virus (RRV); however, prevalence varies substantially around the country. Modeling estimated a yearly risk of 8 to 11 potentially RRV-viremic fresh blood components nationwide. This study aimed to measure the occurrence of RRV viremia among donors who donated at Australian collection centers located in areas with significant RRV transmission during one peak season...

Multi-drug delivery systems, which may be promising solution to overcome obstacles, have limited the clinical success of multi-drug combination therapies to treat cancer. To this end, we used three different anticancer agents, Cu(BpT)Br, NAMI-A, and doxorubicin (DOX), to build human serum albumin (HSA)-based multi-drug delivery systems in a breast cancer model to investigate the therapeutic efficacy of overcoming single drug (DOX) resistance to cancer cells in vivo, and to regulate the drugs' release from HSA...

As the need for the organ donation increases, strategies to increase kidney transplantation (KT) through expanded living donation have become essential. These include kidney paired donation (KPD) programs and desensitization in incompatible transplantations. KPD enables kidney transplant candidates with incompatible living donors to join a registry with other incompatible pairs in order to find potentially compatible living donor. Positive cross match and ABO incompatible transplantation has been successfully accomplished in selective cases with several pre-conditionings...

Biofabrication techniques have endeavored to improve the regeneration of the peripheral nervous system (PNS), but nothing has surpassed the performance of current clinical practices. However, these current approaches have intrinsic limitations that compromise patient care. The "gold standard" autograft provides the best outcomes but requires suitable donor material, while implantable hollow nerve guide conduits (NGCs) can only repair small nerve defects. This review places emphasis on approaches that create structural cues within a hollow NGC lumen in order to match or exceed the regenerative performance of the autograft...

REVIEW
Georges Nasrallah, Fouad G Souki
PURPOSE OF REVIEW: Laparoscopic kidney surgery is commonly used for living donor, partial, and total tumor nephrectomy. The successful emergence of laparoscopic technique was justified by the many benefits offered such as reduced blood loss, tissue trauma, pain, and hospital stay. However, this comes at the expense of physiologic changes and complications secondary to pneumoperitoneum, surgical technique, and patient positioning with significant challenges in anesthetic management. RECENT FINDINGS: A variety of laparoscopic approaches (transperitoneal, retroperitoneal, hand-assisted, robotic) are used with some having advantages over others...

Asparagine (Asn) is a powerful turn-inducer residue, with a large propensity to occupy the second position in the central region of β-turns of proteins. The present work aims at investigating the role of a local anchoring between the Asn side chain and the main chain in this remarkable property. For this purpose, the H-bonding patterns of an asparagine residue in an isolated protein chain fragment forming a γ- or a β-turn have been determined using IR/UV double resonance gas phase spectroscopy on laser-desorbed, jet-cooled short models in conjunction with relevant quantum chemistry calculations...
