life in comparison to normative data. Future clinical studies on non-unions should focus on patient-related outcome measures. Newly emerging treatment strategies and interdisciplinary approaches should be implemented to improve the overall quality of life of non-union patients.
The use of proximal femoral replacements (PFR) has been recently described for catastrophic internal fixation failures. PFR is an attractive treatment option because it is technically straightforward and allows for immediate mobilization of the patient. The aim of the study was to determine the survivorship, functional outcome and complications' rate in a group of elderly patients who underwent proximal femoral replacement as a salvage treatment after femur cephalomedullary nails' mechanical failures.

We evaluated 21 patients who underwent salvage of a failed cephalomedullary nail by using a single design PFR at our institution between 2014-2017. A cemented stem was used in all cases. Radiographs were assessed for fractures, sign of loosening, presence of heterotopic ossification and leg length discrepancy. Functional evaluation was performed through Harris Hip Score (HHS), FIM™ and Time Up and Go test (TUG). Kaplan-Meier estimator was used to determine the overall implants' survival.

The average age atation is the most common complication to bear in mind within the first six months after surgery.
The aim of this manuscript is to compare characteristics, management, and outcomes of patients with severe Traumatic Brain Injury (TBI) between Australia, the United Kingdom (UK) and Europe.

We enrolled patients with severe TBI in Victoria, Australia (OzENTER-TBI), in the UK and Europe (CENTER-TBI) from 2015 to 2017. Main outcome measures were mortality and unfavourable outcome (Glasgow Outcome Scale Extended <5) 6 months after injury. Expected outcomes were compared according to the IMPACT-CT prognostic model, with observed to expected (O/E) ratios and 95% confidence intervals.

We included 107 patients from Australia, 171 from UK, and 596 from Europe. Compared to the UK and Europe, patients in Australia were younger (median 32 vs 44 vs 44 years), a larger proportion had secondary brain insults including hypotension (30% vs 17% vs 21%) and a larger proportion received ICP monitoring (75% vs 74% vs 58%). Hospital length of stay was shorter in Australia than in the UK (median 17 vs 23 vs 16 days), and K, and Europe; Australian patients are younger and have a higher rate of secondary brain insults. Despite some differences in management and discharge policies, mortality was less than expected overall, and did not differ between regions. Functional outcomes were similar between regions, but worse than expected, emphasizing the need to improve treatment for patients with severe TBI.Sialidases (neuraminidases, EC 3.2.1.18) are widely distributed in biological systems but there are only scarce data on its production by filamentous fungi. The aim of this study was to obtain information about sialidase distribution in filamentous fungi from non-clinical isolates, to determine availability of sialidase gene, and to select a perspective producer. A total of 113 fungal strains belonging to Ascomycota and Zygomycota compassing 21 genera and 51 species were screened. Among them, 77 strains (11 orders, 14 families and 16 genera) were able to synthesize sialidase. click here Present data showed a habitat-dependent variation of sialidase activity between species and within species, depending on location. Sialidase gene was identified in sialidase-positive and sialidase-negative strains. . Among three perspective strains, the best producer was chosen based on their sialidase production depending on type of cultivation, medium composition, and growth temperature. The selected P. griseofulvum Р29 was cultivated in 3L bioreactor at 20 °C on medium supplemented with 0.5% milk whey. The results demonstrated better growth and 2.3-fold higher maximum enzyme activity compared to the shaken flask cultures. Moreover, the early occurring maximum (48 h) is an important prerequisite for future up scaling of the process.Diseases caused by rust fungi pose a significant threat to global plant production. Although carotenoid pigments are produced in spores of nearly all rust species, the corresponding biosynthesis pathway(s) have not been investigated. Here, candidate genes for carotenoid biosynthesis in Puccinia graminis f. sp. tritici (Pgt) were identified, cloned and functionally complemented using specifically engineered strains of Escherichia coli. A part of the carotenoid biosynthesis pathway in rust fungi was elucidated, with only two genes, CrtYB and CrtI, catalysing the reactions from geranyl-geranyl diphosphate (GGPP) to γ-carotene. The CrtYB gene encodes a bi-functional lycopene cyclase/phytoene synthase, which catalyses the condensation of two GGPP into phytoene, as well as the cyclisation of the ψ-end of lycopene to form γ-carotene. The CrtI gene encodes a phytoene desaturase that carries out four successive desaturations of phytoene, through the intermediates phytofluene and neurosporene to lycopene. The evolution of carotenoid pigmentation in rust fungi, including Pgt, P. graminis avenae, P. graminis secalis (Pgs), P. graminis lolli, P. striiformis f. sp. tritici, P. striiformis f. sp. pseudohordei, P. striiformis f. sp. hordei, the "scabrum" rust (putative hybrids between Pgt and Pgs), P. triticina, and P. hordei, was investigated by phylogenetic analysis. Both CrtYB and CrtI were found to be closely related among rust fungi, other pathogenic fungi, and some aphids. Our results provide a springboard to increase the understanding of the physiological role(s) of carotenoid pigments in rust fungi, to better understand evolution within the Pucciniales, and to develop robust molecular diagnostics for rust fungi.Small RNAs (sRNAs) are key factors in the regulation of gene expression. Recently, a new class of regulatory sRNAs derived from tRNAs was described, the tRNA-derived RNA fragments (tRFs). Such RNAs range in length from 14 to 30 nucleotides and are produced from both mature and primary tRNA transcripts, with very specific cleavage sites along the tRNA sequence. Although several mechanisms have been proposed for how tRFs mediate regulation of gene expression, the exact mechanism of tRF biogenesis and its dependency upon the RNAi pathway remain unclear. Cryptococcus gattii and Cryptococcus neoformans are basidiomycetous yeasts and important human pathogens. While C. neoformans is RNAi proficient, C. gattii VGII has lost essential RNAi genes. Here, we sought to identify the tRF production profile in C. gattii VGII and C. neoformans in order to assess the RNAi-dependency of tRF production in these fungal species. We developed a RNA-sequencing-based tRF prediction workflow designed to improve the currently available prediction tools. Using this methodology, we were able to identify tRFs in both organisms. Despite the loss of the RNAi pathway, C. gattii VGII displayed a number of identified tRFs that did not differ significantly from those observed in C. neoformans. The analysis of predicted tRF targets revealed that a higher number of targets was found for C. gattii VGII tRFs compared to C. neoformans tRFs. These results support the idea that tRFs are at least partially independent of the canonical RNAi machinery, raising questions about possible compensatory roles of alternative regulatory RNAs in the absence of a functional RNAi pathway.Candida haemulonii species complex (C. haemulonii, C. haemulonii var. vulnera and Candida duobushaemulonii) is composed by emerging and multidrug-resistant (MDR) yeasts. Candidiasis, the disease caused by these species, is difficult to treat and culminates in clinical failures and patient death. It is well-known that Candida peptidases play important roles in the fungus-host interactions, and hence these enzymes are promising targets for developing new antifungal drugs. Recently, serine-type peptidases were described in clinical isolates of C. haemulonii complex with the ability to cleave relevant key host proteins. Herein, the effects of serine peptidase inhibitors (SPIs) on the cell biology of this fungal complex were evaluated. Initially, eight distinct SPIs (phenylmethylsulfonyl fluoride - PMSF, 4-(2-aminoethyl) benzenesulfonyl fluoride hydrochloride - AEBSF, N-α-tosyl-l-lysine chloromethyl ketone hydrochloride - TLCK, N-p-tosyl-l-phenylalanine chloromethyl ketone - TPCK, simeprevir, boceprevir, danoprevir and telaprevir) were tested on the fungal growth. TPCK showed the best efficacy in controlling cell proliferation, being selected for the following experiments. This SPI induced changes in the architecture of yeast cells, as observed by scanning electron microscopy, besides injuries at the plasma membrane and reduction in the ergosterol content. TPCK also diminished the ability of yeasts to adhere to abiotic (polystyrene and glass) and biotic (murine macrophages) surfaces in a typically concentration-dependent manner. In addition, the 24 h-treatment of the mature biofilm promoted a decrease in biomass, viability and extracellular matrix. Altogether, our results highlight that SPIs may be promising new therapeutic agents in the treatment of candidiasis caused by emergent, opportunistic and MDR species forming the C. haemulonii complex.Intracellular metabolites were evaluated during the continuous growth of Trichoderma harzianum P49P11 under carbon-limited conditions. Four different conditions in duplicate were investigated (10 and 20 g/L of glucose, 5.26/5.26 g/L of fructose/glucose and 10 g/L of sucrose in the feed). Differences in the values of some specific concentrations of intracellular metabolites were observed at steady-state for the duplicates. The presence of extracellular polysaccharide was confirmed in the supernatant of all conditions based on FT-IR and proton NMR. Fragments of polysaccharides from the cell wall could be released due to the shear stress and since the cells can consume them under carbon-limited conditions, this could create an unpredictable carbon flow rate into the cells. According to the values of the metabolite concentrations, it was considered that the consumption of those fragments was interfering with the analysis.TPPP-like proteins, exhibiting microtubule stabilizing function, constitute a eukaryotic superfamily, characterized by the presence of the p25alpha domain. TPPPs in the strict sense are present in animals except Trichoplax adhaerens, which instead contains apicortin where a part of the p25alpha domain is combined with a DCX domain. Apicortin is absent in other animals and occurs mostly in the protozoan phylum, Apicomplexa. A strong correlation between the occurrence of p25alpha domain and that of the eukaryotic cilium/flagellum was suggested. Species of the deeper branching clades of Fungi possess flagellum but others lost it thus investigation of fungal genomes can help testing of this suggestion. Indeed, these proteins are present in early branching Fungi. Both TPPP and apicortin are present in Rozellomycota (Cryptomycota) and Chytridiomycota, TPPP in Blastocladiomycota, apicortin in Neocallimastigomycota, Monoblepharomycota and the non-flagellated Mucoromycota. Beside the "normal" TPPP occurring in animals, a special, fungal-type TPPP is also present in Fungi, in which a part of the p25alpha domain is duplicated.
