MicroRNAs (miRNAs) are small (about 22 nucleotides) noncoding RNAs, which were highly conserved among mammals. They have ushered in a new era in molecular biology over twenty years. They can negatively regulate gene expression at the posttranscriptional level through the principle of complementary base pairing with the 3' untranslated region (UTR) of their target mRNAs and induce their degradation. They involve in tissue morphogenesis, cellular processes like apoptosis, and major signaling pathways. Previous studies have promoted our understanding that miRNAs play an important role in myogenesis and have a big impact on muscle mass, muscle fiber type and muscle diseases...

Plant cytoplasmic male sterility (CMS) is an important phenomenon and is widely utilized in hybrid crop breeding. The Wild Abortive CMS (CMS-WA), a well-known CMS type, has been successfully applied in the commercial production of hybrid rice seeds for more than 40 years. The CMS-WA causal gene WA352 encodes a novel transmenbrane protein and the interacts with the mitochondrial copper chaperone COX11, triggering reactive oxygen species production and resulting in male sterility in CMS-WA lines. However, the structure of WA352 is currently unknown, and the structural mechanism whereby WA352 perturbs COX11 function to cause CMS remains largely unknown...

AIM: The purpose of this study was to explore the evolution of cultural competence in Taiwanese paediatric nurses. BACKGROUND: Because transnational marriage has become a social phenomenon in Taiwan, the proportion of newborns of new immigrant mothers accounts for 8-10% of total births every year. Since family-centered care is the core value of paediatric nursing, it is necessary to teach caregivers how to take care of hospitalized children and perform related nursing care as well as to determine what difficulties nurses will encounter when they care for patients from diverse cultures and to find solutions for these problems...

The opening of the gravitational wave window by ground-based laser interferometers has made possible many new tests of gravity, including the first constraints on polarization. It is hoped that, within the next decade, pulsar timing will extend the window by making the first detections in the nanohertz frequency regime. Pulsar timing offers several advantages over ground-based interferometers for constraining the polarization of gravitational waves due to the many projections of the polarization pattern provided by the different lines of sight to the pulsars, and the enhanced response to longitudinal polarizations...

In recent years, intriguing hints for the violation of lepton flavor universality (LFU) have been accumulated in semileptonic B decays, both in the charged-current transitions b→cℓ^{-}ν[over ¯]_{ℓ} (i.e., R_{D}, R_{D^{*}}, and R_{J/ψ}) and the neutral-current transitions b→sℓ^{+}ℓ^{-} (i.e., R_{K} and R_{K^{*}}). Hints for LFU violation in R_{D^{(*)}} and R_{J/ψ} point at large deviations from the standard model (SM) in processes involving tau leptons. Moreover, LHCb has reported deviations from the SM expectations in b→sμ^{+}μ^{-} processes as well as in the ratios R_{K} and R_{K^{*}}, which together point at new physics (NP) affecting muons with a high significance...

While synthetic methods for the grafting of nanoparticles or photoactive molecules onto carbon nanotubes (CNTs) have been developed in the last years, a very limited number of reports have appeared on the grafting of single-molecule magnets (SMMs) onto CNTs. There are many potential causes, mainly focused on the fact that the attachment of molecules on surfaces remains not trivial and their magnetic properties are significantly affected upon attachment. Nevertheless, implementation of this particular type of hybrid material in demanding fields such as spintronic devices makes of utmost importance the investigation of new synthetic protocols for effective grafting...

OBJECTIVE Rathke's cleft cysts (RCCs) are benign epithelial lesions of the sellar region typically treated via a transsphenoidal approach with cyst fenestration and drainage. At present, there is limited evidence to guide patient selection for operative treatment. Furthermore, there is minimal literature describing factors contributing to cyst recurrence. METHODS The authors conducted a retrospective analysis of 109 consecutive cases of pathology-confirmed RCCs treated via a transsphenoidal approach at a single center from 1995 to 2016...

OBJECTIVE The overall risk of ischemic stroke from a chronically occluded internal carotid artery (COICA) is around 5%-7% per year despite receiving the best available medical therapy. Here, authors propose a radiographic classification of COICA that can be used as a guide to determine the technical success and safety of endovascular recanalization for symptomatic COICA and to assess the changes in systemic blood pressure following successful revascularization. METHODS The radiographic images of 100 consecutive subjects with COICA were analyzed...

REVIEW

Neurofeedback therapy is a fast-growing field of tinnitus treatment, which is a new type of biofeedback therapy. In the past, the "muscle tone" and "blood flow" were used as feedback signals in biofeedback therapy to treat tinnitus, however there was no long-term follow-up report. Instead, neurofeedback therapy utilizes EEG (electroencephalogram) as the feedback signal, which is also called EEG biofeedback therapy. At present, most treatments of tinnitus only record subjective measures of patients as evaluation indicators, whereas neurofeedback therapy is more convincing for using comprehensive evaluation including changes of brain wave as objective indicators and subjective measures of patients...

Zhidong Gao, Kewei Jiang, Yingjiang Ye, Shan Wang
Gastric stump cancer(GSC) is defined as newly developed remnant stomach cancer following gastrectomy. This definition initially referred to carcinoma detected in the remnant stomach more than 5 years after the primary surgery for a benign disease. Subsequently, this timeframe was extended to 10 years after the primary surgery for a malignant disease. Recently, the concept of "carcinoma in the remnant stomach(CRS)" proposed by the Japanese Gastric Cancer Association was introduced in China. The new definition encompasses all carcinomas arising in the remnant stomach following gastrectomy, irrespective of the histology of the primary lesion, extent of resection, or reconstruction method...

Phosphorus containing molecules have seen widespread applications in the development of innovative metal-ligand catalysts and materials. In recent years, the implementation of late-stage modifications of phosphorus derivatives via ortho-regioselective C-H bond functionalisation has led to faster and better ways for the synthesis of complex ligands by creating new reactions with low impact on the environment. This Feature article highlights transition-metal catalysed regioselective C-H bond functionalisation of phosphorus-containing molecules, in which the phosphorus containing unit plays the role of a directing group for C-H bond activation and the synthesis of new functional phosphorus derivatives...
