Therefore, it is possible to postulate that inhibiting its function may not cause serious side effects. In addition, eEF2K is a peculiar kinase molecularly different from most of other mammalian kinases and new compounds that inhibit eEF2K should not necessarily interfere with other important protein kinases. In this review we will critically summarize the evidence supporting the role of the altered eEF2K/eEF2 pathway in defined neurological diseases and its implications in curing these diseases in animal models, and possibly in humans, by targeting eEF2K activity. PURPOSE Synchrotron microbeam radiation therapy (MRT) is based on the spatial fractionation of the incident, highly collimated synchrotron beam into arrays of parallel microbeams depositing several hundred grays. It appears relevant to combine MRT with a conventional treatment course, preparing a treatment scheme for future patients in clinical trials. The efficiency of MRT delivered after several broad beam (BB) fractions to palliate of F98 brain tumors in rats in comparison with BB fractions alone was evaluated in this study. MATERIALS/METHODS Rats bearing 106 F98 cells implanted in the caudate nucleus were irradiated by 5 fractions in broad beam (BB) mode (3x6Gy + 2x8Gy BB) or by 2 boost fractions in MRT mode, of a total of 5 fractions (3x6Gy BB + MRT 2x8Gy valley dose; peak dose 181Gy (50/200μm)). Tumor growth was evaluated in vivo by MRI follow up at T-1, T7, T12 T15, T20, T25 days, after radiotherapy, and by histology and FACS studies. RESULTS MRT-boosted tumors displayed lower cell density and cell proliferation compared with BB-irradiated tumors. The MRT boost completely stopped tumor growth during ∼4 weeks and led to a significant increase in MST, while tumors treated with BB alone recurred within few days after the last radiation fraction. CONCLUSIONS The first evidence is presented that MRT, delivered as a boost of a conventional fractionated irradiation by orthovoltage broad X-ray beams, is feasible and more efficient than a conventional radiotherapy alone. Segmentation of brain tissue in diffusion MRI image space has some unique advantages. A novel segmentation method using the direction-averaged diffusion weighted imaging (DWI) signal is proposed. Two images can be obtained from the fitting of the direction-averaged DWI signal as a function of b-value one with superior contrast between the gray matter and white matter; one with prominent CSF contrast. A pseudo T1 weighted image can be constructed and standard segmentation tools can be applied. The method was tested on the HCP dataset using SPM12, and showed good agreement with segmentation using the T1 weighted image with the same resolution. The Dice score was all greater than 0.88 for GM or WM with full DWI data and very stable against subsampling of the DWI data in number of diffusion directions, number of shells, and spatial resolution. BACKGROUND Obstructive sleep apnea (OSA) is associated with increased risk of postoperative complications in non-cardiac surgery, with limited literature on cardiac surgical patients. We compared perioperative outcomes of patients with OSA to those without OSA undergoing cardiac surgery. METHODS This was a retrospective single center cohort study of adult patients who underwent cardiac surgery from January 2010 to April 2017. Our aim was to compare outcomes of patients with OSA to those without OSA including length of stay, readmissions, hospital mortality, and short-term outcomes. RESULTS 8612 patients during the study period included 2636 (30.6%) with OSA. Patients with OSA had a higher median length-of-stay (6 vs 5 days, P 75 years odd ratio 4.10, 95% confidence interval 3.39-4.96). CONCLUSIONS OSA patients had a higher mean length-of-stay, were more likely to have a prolonged length-of-stay, more likely to discharge to location other than home, and had a higher 30-day readmission rate. This suggests higher resource utilization is required to care for OSA patients following cardiac surgery. BACKGROUND Left atrioventricular valvar regurgitation (LAVVR) following atrioventricular canal (AVC) repair remains a significant cause of morbidity. Papillary muscle arrangement may be important. The implications of left mural leaflet morphology have not been investigated. We examined anatomic characteristics of the LAVV to determine possible associations with postoperative LAVVR. METHODS All patients with biventricular AVC repair at our institution between 1/1/11 and 12/31/16 with necessary imaging were retrospectively reviewed. KY 12420 chemical structure Papillary muscle structure and novel measures of the left mural leaflet were assessed from preoperative echocardiograms, and degree of LAVVR from the first and last available follow-up echocardiograms. Associations with degree of early and late postoperative LAVVR were assessed with t-tests, ANOVA or Chi-square/Fisher's exact tests, and multivariable logistic regression. RESULTS Fifty-eight patients (37% of 156) had significant (moderate or severe) early postoperative LAVVR. link2 Thirty (32% of 93) had significant LAVVR after 6 or more months. Fewer patients with closely-spaced or asymmetric papillary muscles had moderate or severe late LAVVR versus those with widely-spaced papillary muscles (17% versus 40%, P=0.019). Controlling for weight at surgery, genetic syndromes and bypass time, widely-spaced papillary muscles increased the odds ratio for late LAVVR to 3.6 (P=0.026). Larger mural leaflet area was also associated with late LAVVR on univariable and multivariable analyses (P=0.019; P=0.023). A third of patients with significant late LAVVR had no significant early postoperative regurgitation. CONCLUSIONS Mural leaflet and papillary muscle anatomy are associated with late LAVVR after AVC repair. Late regurgitation can develop in the absence of early LAVVR, suggesting different mechanisms. Gastric tube reconstruction is now the method most frequently used for digestive tract reconstruction after the resection of esophageal carcinoma. In our institute, a "flexible" gastric tube designed to supply a sufficient amount of blood to the tip of the gastric tube (the same as a subtotal gastric tube) and simultaneously provide sufficient length for tension-free anastomosis in the cervical surgical field (the same as a narrow gastric tube) was introduced. This gastric tube formation method has contributed to improving the rate of anastomotic leakage. Nitric oxide (NO) is an important signaling molecule implicated in numerous physiological and pathological conditions. NO homeostasis is crucial to its proper functions and misregulation of NO production is implicated in a large number of pathologies. The effect of NO depends on the cell microenvironment as well as its concentration, spatial, and temporal constraints. Thus, the visualization and monitoring of NO in living systems would be valuable for understanding the origin, activities, and biological effects of NO. This review focuses on organic small-molecule fluorescent probes for selective detection and imaging of endogenous NO in vitro and in vivo. The progress suggests that fluorescence imaging is a vital and rapidly technology for real-time detection of NO in biological system. Infectious diseases are adversely affecting aquaculture practices throughout world and Asian countries are no exception. Indian aquaculture practices are facing serious setback due to a variety of infectious agent's which are responsible for severe mortality and morbidity of all the cultured freshwater fish species leading to severe economic losses. The emergence of antibiotic resistant pattern, residual effect and environmental degradation due to indiscriminate use of antibiotics has necessitates the development of suitable alternate prophylaxis measures for better protection. In this regard, vaccine(s) has proved to be an effective strategy against pathogens to improve the fish production. Over the years numerous studies have been conducted to develop vaccine(s) against different pathogens. While most of the efforts are made to develop vaccine against bacterial pathogens especially against Aeromoniasis and Edwardsiellosis, few attempts have also been made against certain other bacterial, parasitic and fungal pathogens as well. Despite various successful experimental attempts, till date no vaccines against any of the pathogens are commercially available for Indian aquaculture practices. This review principally focuses on the current state of art in the development of vaccine against different pathogens in general and Aeromonas hydrophila in particular since the bacterium is a major pathogen which is involved in a number of disease conditions in all the cultured fish species in India. Herein in this review, details of various approaches made to find out a potential vaccine candidate which in turn can induce protective immune responses in host alongwith the constraints associated with it in developing a suitable vaccine against this bacterium and its market potential have been illustrated from an Indian perspective. Up to now, many previous reports have emphasized that Annexins (ANX) family played an important role in immune responses. Aeromonas hydrophila (A. hydrophila), the most common zoonotic pathogenic bacteria of yellow catfish (Pelteobagrus fulvidraco), can cause serious economic loss, especially to yellow catfish with high economic value. In our previous work, we demonstrated that synthetic oligodeoxynucleotides containing CpG motifs (CpG ODN) owned powerful immunostimulatory activity. However, the relationship among Pelteobagrus fulvidraco Annexins (Pf_ANX), CpG ODN and A. hydrophila is unknown. Therefore, we cloned Pf_ANX1-6 genes and analyzed its sequences, structures, genetic evolution, post-translation modifications (PTMs), Ca2+ ion binding sites and tissue distribution to reveal the relevance. In addition, we investigated the responses of ANXA1-6 and cytokines in intestine and spleen as well as morbidity/survival rate of fish post CpG ODN immunization and/or A. hydrophila infection. The results showed that compared with challenge alone (challenge-CK) group, the CpG immunization following challenge (CpG-challenge) group displayed relatively flat IL-1β level throughout in both organs. Meanwhile, the expression of IFN-γ and morbidity/survival rate of fish in CpG-challenge group showed a great improvement compared with the challenge-CK group. Our results indicated that CpG ODN could improve morbidity/survival by up-regulating Pf_ANXA 1, 2 and 5 in the intestine and spleen to ameliorate inflammatory responses and promote anti-infective responses. link3 Our findings offer some important insights into ANX related to the immunity of fish infection and lay a theoretical basis for the prevention and treatment of fish infections. Fish NK-lysin (NKL), an orthologous to human granulysin, exerts a dual role as an antimicrobial peptide (AMP) and as a direct executor of T cytotoxic and natural killer cells during the cell-mediated cytotoxic (CMC) response. Although its best-known function is as AMP against bacteria, recent studies point to a special role of NKL in antiviral responses. Nodavirus (NNV) is a spreading threat in Mediterranean aquaculture. In this study, we have identified and compared the expression pattern of European sea bass and gilthead seabream NKL and evaluated its transcription in different tissues and its regulation in head-kidney leucocyte (HKLs) stimulated in vitro with different immunostimulants, under CMC response and upon an in vivo infection with NNV. Our results showed that nkl transcription is highly expressed in spleen, thymus and skin with species-specific differences. Interestingly, the expression pattern in both species was very different upon treatment. While sea bass nkl transcription was increased in HKLs by the T mitogen phytohemagglutinin all the stimulators inhibited it in seabream HKLs.
