Measurement of the cross-sectional area (CSA) of peripheral nerves using ultrasound is useful in the evaluation of focal lesions like entrapment syndromes and inflammatory polyneuropathies. Here, a systematic review and meta-analysis of published CSA reference values for upper extremity nerves was performed.

Available to date nerve ultrasound studies on healthy adults were included and a meta-analysis for CSA was provided of the following nerves median nerve at the wrist, forearm, upper arm; ulnar nerve at the Guyon's canal, forearm, elbow, upper arm; radial nerve at the upper arm. Regression and correlation analyses for age, gender, height, weight, geographic continents and publication year are reported.

Seventy-four studies with 4186 healthy volunteers (mean age 42.7years) and 18,226 examined nerve sites were included. The calculated mean pooled CSA of the median nerve at the wrist was 8.3mm
(95% confidence interval [95% CI] 7.9-8.7, n=4071), at the forearm 6.4mm
(95% CI 5.9-6.9, n=3021), at the unal standardized evaluation protocol.In fission yeast, siRNA generated by RNA interference (RNAi) factors plays critical roles in establishment and maintenance of heterochromatin. To achieve efficient siRNA synthesis, RNAi factors assemble on heterochromatin via association with Swi6, a homologue of heterochromatin protein 1 (HP1), and heterochromatic noncoding RNA (hncRNA) retained on chromatin. In addition, spliceosomes formed on hncRNA introns recruit RNAi factors to hncRNA and heterochromatin. Small nuclear RNAs, components of the spliceosome, have a trimethylguanosine (TMG) cap that is generated by Tgs1-dependent hypermethylation of the normal m7G cap; this cap is required for efficient splicing of some mRNAs in budding yeast and Drosophila. In this study, we found that loss of Tgs1 in fission yeast destabilizes centromeric heterochromatin. Tgs1 was required for Swi6-independent siRNA synthesis, as well as for the establishment of centromeric heterochromatin. Loss of Tgs1 affected the splicing efficiency of hncRNA introns in the absence of Swi6. Furthermore, some hncRNAs have a TMG cap, and we found that loss of Tgs1 diminished the chromatin binding of these hncRNAs. Together, these results suggest that the Tgs1-dependent TMG cap plays critical roles in establishment of heterochromatin by ensuring spliceosome-dependent recruitment of RNAi factors and regulating the binding between chromatin and hncRNA.Granulosa cell tumour, an ovarian neoplasm of stromal origin, is an important tumour related to oestrogenic dominance syndrome and cystic endometrial hyperplasia-pyometra complex. In order to analyse ovarian tumour´s malignant potential, immunohistochemical markers can be used, such as anti-HER2 and anti-Ki-67. The aim of this study was to evaluate the expression of immunohistochemical markers HER-2 and Ki-67 in granulosa cell tumour from bitches´ ovaries. In HER-2 immunomarker analysis using the HercepTest® method, most tumours were classified as 2+ (moderate labelling). Concerning Ki-67 immunomarker, only one case was described as having a high proliferative index. An association was found between immunostained cell percentage by anti-HER-2 antibodies and high pleomorphism, represented by the pattern of follicular/trabecular tumour arrangement. There was no correlation between anti-Ki-67 and anti-HER-2 antibody immunostaining intensities, probably due to only one case with a high Ki-67 index. With an effective protocol for HER-2 and Ki-67 immunohistochemical identification in granulosa cell tumours in bitches, it was possible to characterize this neoplasm proliferation profile.Renal cell carcinoma (RCC) is not a single disease but is made up of several different histologically defined subtypes that are associated with distinct genetic alterations which require subtype specific management and treatment. Papillary renal cell carcinoma (pRCC) is the second most common subtype after conventional/clear cell RCC (ccRCC), representing ~20% of cases, and is subcategorized into type 1 and type 2 pRCC. It is important for preclinical studies to have cell lines that accurately represent each specific RCC subtype. This study characterizes seven cell lines derived from both primary and metastatic sites of type 1 pRCC, including the first cell line derived from a hereditary papillary renal carcinoma (HPRC)-associated tumor. Complete or partial gain of chromosome 7 was observed in all cell lines and other common gains of chromosomes 16, 17, or 20 were seen in several cell lines. Activating mutations of MET were present in three cell lines that all demonstrated increased MET phosphorylation in response to HGF and abrogation of MET phosphorylation in response to MET inhibitors. CDKN2A loss due to mutation or gene deletion, associated with poor outcomes in type 1 pRCC patients, was observed in all cell line models. find more Six cell lines formed tumor xenografts in athymic nude mice and thus provide in vivo models of type 1 pRCC. These type 1 pRCC cell lines provide a comprehensive representation of the genetic alterations associated with pRCC that will give insight into the biology of this disease and be ideal preclinical models for therapeutic studies.The current article aims to summarize all possible spectrum of protein-protein interactions for thromboxane A synthase (CYP5A1) and prostacyclin synthase (CYP8A1). These enzymes metabolize the same substrate (prostaglandin H2 ) and can participate in cardiovascular, inflammatory, immune processes, and apoptosis modulation, as well as significantly influence the risk of cancers. Binary protein-protein and multiprotein complexes are of great importance in enzyme-regulating and signal-transduction pathways. However, protein partners of CYP5A1 and CYP8A1 are not yet fully identified, although both synthases are considered as prospective drug targets. At least 36 novel protein partners of CYP5A1 and CYP8A1 were revealed from different tissue types using an approach based on affinity isolation and mass spectrometry. Enrichment analysis showed that these proteins have different molecular functions folding (refolding), unfolded protein and chaperon binding, protein transport (export/import), posttranslational modification, protein domain-specific binding, antioxidant activity, and glutathione homeostasis.
