Therefore renal protective therapy is very important in these severely ill patients. AIM Several renal protective strategies have been postulated during recent decades, which came from pathophysiologic concepts and have been contradicted or changed during the last few years. So lessons had to be learned in AKI, leading to new, in many cases completely reversed preventive and therapeutic concepts which may also be important for protection in other organs. RECENT FINDINGS Most important for renal protection is the early identification of patients at risk for AKI or with acute kidney damage before renal function further deteriorates. A stage-based management of AKI comprises more general measures like discontinuation of the nephrotoxic agent but most importantly early hemodynamic stabilization. Recent research has contradicted that AKI is for AKI prevention and therapy in the future.

These pathogens can attach to enterocytes and lead to the formation of a pedestal-like structure. Invasins and intimins belong to type Ve secretion systems, and the N-terminal β-barrel domain acts as a translocation pore to secrete the C-terminal passenger domain. However, the relationship between invasins/intimins and type III secretion system (T3SS) has been poorly studied. Based on the transposon insertion mutant library of Edwardsiella piscicida, we got a transposon insertion mutant with significant T3SS defect and identified the mutated gene ETAE_0323 (named inV later). This gene encoded a protein with 2359 amino acid residues and was predicted to be an invasin. To study the relationship between InV and T3SS, strains with N-terminus or C-terminus deleted InV fragments were made. However, none of them was able to copy the phenotype of the transposon insertion mutant previously identified. The localization of InV in ΔT3SS strain was not significantly different from WT, suggesting that the T3SS defect in the transposon insertion mutant was likely to be caused by polar effect. Nevertheless, depletion of inV still showed dramatic internalization and virulence defect in HeLa cell and zebrafish model, respectively, suggesting InV as a virulence related protein.L-asparaginase (E.C.3.5.1.1) is an important enzyme that has been purified and characterized for over decades to study and evaluate its anti-carcinogenic activity against different lymphoproliferative disorders such as acute lymphoblastic leukemia (ALL) and Hodgkin's lymphoma. The ability of the enzyme to convert L-asparagine into aspartic acid and ammonia is the reason behind its anti-cancerous activity. Apart from its medicinal uses, it is widely used in food industry to tackle acrylamide, a probable human carcinogen and, production in carbohydrate-rich foods cooked at high temperatures. There are variety of organisms including microorganisms such as bacteria, fungi, algae, and plants that produce L-asparaginase. The enzyme obtained from different microbial and plant sources have different physiochemical properties and kinetic parameters. L-asparaginases have an optimum pH range between 6 and 10 and an optimum temperature between 37 and 85 °C. This article has reviewed the lowest molecular mass for L-asparaginase in Yersinia pseudotuberculosis Q66CJ2 which is 36.27 kDa, while the highest for Pseudomonas otitidis which has a molecular mass of 205 ± 3 kDa. This review is an attempt to summarize most of the available sources, their phylogenetic relationships, purification methods, data regarding different physiochemical and kinetic properties of L-asparaginase.OBJECTIVES To assess the safety and efficacy of percutaneous microwave ablation (MWA) of histologically proven T1 renal cell carcinoma (RCC). METHODS We analysed patients with a histologically proven RCC (≤ 7 cm) treated by MWA from April 2012-April 2018. Primary and secondary efficacy, local tumour recurrence (LTR), morbidity and mortality were reported. Efficacy was defined as no residual tumour enhancement on follow-up imaging 1 month after the first ablation (primary efficacy) and after re-ablation(s) for residual disease (secondary efficacy). Adverse events (AE) were registered by the Clavien-Dindo classification and the common terminology criteria for AE. Univariable and multivariable logistic regression analyses were performed to investigate a relation among pre-treatment factors incomplete ablation and complications. RESULTS In 100 patients, a total of 108 RCCs (85 T1a and 23 T1b) were treated by MWA. Median size was 3.2 cm (IQR 2.4-4.0). Primary efficacy was 89% (95%CI 0.81-0.94) for T1a lesions and 52% (95%CI 0.31-0.73) for T1b lesions (p  3-5 were observed (2 T1a, 4 T1b, p = 0.045). Multivariable analysis showed that mR.E.N.A.L. nephrometry was independently associated with incomplete ablation (p = 0.012). CONCLUSION Microwave ablation is safe and effective for T1a and T1b RCC lesions with a significantly lower primary efficacy for T1b lesions.Protein phosphorylation is the most frequent post-translational modification by which the properties of eukaryotic proteins can be reversibly modified. In humans, over 500 protein kinases generate a huge phosphoproteome including more than 200,000 individual phosphosites, a figure which is still continuously increasing. The in vivo selectivity of protein kinases is the outcome of a multifaceted and finely tuned process where numerous factors play an integrated role. To gain information about the actual contribution to this process of local features that reflect the interaction of the protein targets with the catalytic site of the kinases, the prevalence of the commonest motifs determining the consensus sequence of Ser/Thr-specific kinases has been examined in the whole human phosphoproteome and in the phosphoproteomes generated by a panel of the 47 most pleiotropic protein kinases. Our analysis shows that (1) most phosphosites do conform to at least one of the motifs considered, with a substantial proportion conforming to two or more of them; (2) some motifs, with special reference to the one recognized by protein kinase CK2 (pS/pT-x-x-E/D) are very promiscuous, being abundantly represented also at the phosphosites of all the other protein kinases considered; (3) by contrast, other phosphorylated motifs, notably pS/pT-P, pS/pT-Q and pS-x-E, are more discriminatory and selective, being nearly absent in the phosphosites that are not attributable to certain categories of kinases. The information provided will prove helpful to make reliable inferences based on the manual inspection of individual phosphosites.Intramembrane proteolysis describes the cleavage of substrate proteins within their hydrophobic transmembrane segments. Several families of intramembrane proteases have been identified including the aspartyl proteases Signal peptide peptidase (SPP) and its homologues, the SPP-like (SPPL) proteases SPPL2a, SPPL2b, SPPL2c and SPPL3. As presenilin homologues, they employ a similar catalytic mechanism as the well-studied γ-secretase. selleck inhibitor However, SPP/SPPL proteases cleave transmembrane proteins with a type II topology. The characterisation of SPP/SPPL-deficient mouse models has highlighted a still growing spectrum of biological functions and also promoted the substrate discovery of these proteases. In this review, we will summarise the current hypotheses how phenotypes of these mouse models are linked to the molecular function of the enzymes. At the cellular level, SPP/SPPL-mediated cleavage events rather provide specific regulatory switches than unspecific bulk proteolysis. By this means, a plethora of different cell biological pathways is influenced including signal transduction, membrane trafficking and protein glycosylation.Faithful chromosome segregation during mitosis in eukaryotes requires attachment of the kinetochore, a large protein complex assembled on the centromere of each chromosome, to the spindle microtubules. The kinetochore is a structural interface for the microtubule attachment and provides molecular surveillance mechanisms that monitor and ensure the precise microtubule attachment as well, including error correction and spindle assembly checkpoint. During mitotic progression, the kinetochore undergoes dynamic morphological changes that are observable through electron microscopy as well as through fluorescence microscopy. These structural changes might be associated with the kinetochore function. In this review, we summarize how the dynamics of kinetochore morphology are associated with its functions and discuss recent findings on the switching of protein interaction networks in the kinetochore during cell cycle progression.OBJECTIVES The Central African Republic (CAR), a site of recurrent disease emergence, developed a noteworthy epidemiological surveillance system from the colonial period, but its health measures have remained among the world's lowest. To understand this disparity between surveillance and public health, we examined selected moments in its history of surveillance and changing relations with public health structures. METHODS We conducted archival research in CAR and French archives and 18 semi-structured interviews with key researchers working in CAR. RESULTS We find long-term continuities in privileging surveillance over the health system and population health, making the CAR a "hotspot" for emerging diseases and a "blind spot" of primary health care. From the colonial period, the country attracted considerable support for surveillance, without concomitant investment in public health system. Political disputes and financial constraints have obscured real primary care needs on the ground. CONCLUSIONS As both a hotspot and a blind spot for global health, the CAR signals the need to reorient health interventions to address the long-term health of Central African people.OBJECTIVES To explore the longitudinal association between food groups and memory loss and comorbid heart disease and diabetes (both Type 1 and 2) for people living in New South Wales, Australia. METHODS We assessed 139,096 adults (aged 45 years and over) from the 45 and Up Study who completed both baseline (2006-2009) and follow-up (2012-2015) surveys. Mixed linear and generalized estimating equation models were used to examine the longitudinal associations. RESULTS High consumption of fruit, vegetable and protein-rich food associated with lower odds of memory loss. High consumption of fruit and vegetables also associated with lower odds of comorbid heart disease (p ≤ 0.001). People who aged ≥ 80 years with low consumption of cereals had the highest odds of memory loss and comorbid heart disease than people in other age groups (p  less then  0.01). CONCLUSIONS The results highlighted the longitudinal association of fruit and vegetable in relation to memory loss and comorbid heart disease. Age effects on cereals consumption which have an influence on memory loss and comorbid heart disease.
