OBJECTIVE: Introduction: Medical researchers, who are non-native English speakers, are facing now the growing need to publish their research results in international journals switching to an English-only policy, to apply for grants and scholarship, but at the same time this puts many authors whose native language is not English at a disadvantage compared to their English-speaking counterparts. The aim: This paper aims at analysing the existing parameters of academic writing proficiency of medical undergraduate and postgraduate students; elucidating current approaches to develop academic writing competency and to promote academic multi-literacy of junior researchers, and outlining the general recommendations to improve the quality and sophistication of their writing by incorporating the principles and achievements of academic writing pedagogy into the system of medical training...

PURPOSE: The Memorial Symptom Assessment Scale Short Form (MSAS-SF) is a widely used symptom assessment instrument. Patients who self-complete the MSAS-SF have difficulty following the two-part response format, resulting in incorrectly completed responses. We describe modifications to the response format to improve useability, and rational scoring rules for incorrectly completed items. METHODS: The modified MSAS-SF was completed by 311 women in our Peer and Nurse support Trial to Assist women in Gynaecological Oncology; the PeNTAGOn study...

Transcriptional changes of genes encoded with phytochelatins synthase (PCS) was investigated in rice seedlings exposed to potassium chromate Cr(VI) or chromium nitrate Cr(III) using qRT-PCR. Our study demonstrates that both Cr variants initiated different responses of phytochelatin content and PCS activities in rice tissues. Six putative PCS genes were expressed differentially in response to both Cr species. Comparing gene expression between root/shoots, only LOC_Os05g34290.1 and LOC_Os06g01260.1 genes were expressed in similar patterns in Cr(VI) treatment, while none of them were expressed equally in Cr(III) treatments...

Brain-derived neurotrophic factor (BDNF) is identified as a potent neuroprotective and neuroregenerative agent for many neurological diseases. Regrettably, its delivery to the brain is hampered by poor serum stability and rapid brain clearance. Here, a novel nanoformulation is reported composed of a bio-compatible polymer, poly(ethylene glycol)- b -poly(L-glutamic acid) (PEG-PLE), that hosts the BDNF molecule in a nanoscale complex, termed here Nano-BDNF. Upon simple mixture, Nano-BDNF spontaneously forms uniform spherical particles with a core-shell structure...

Introduction: Glioma is the most frequent malignancy of the adult central nervous system with high recurrence risk and poor prognosis. Understanding the biological molecular mechanisms involved in glioma progression is critical for studying oncogenic mechanisms and improving prognosis. Lysyl oxidase-like 2 (LOXL2) is a kind of lysyl oxidase catalyzing the formation of peptidyl-lysine residues and promoting intramolecular cross-linking, especially for proteins in extracellular matrix. Our study explored the expression pattern of LOXL2 in glioma for the first time and found that its high expression was associated with larger tumor size and advanced tumor grade ( P <0...

Hematogenous recurrence is a challenging clinical finding that often leads to fatalities of patients with gastric cancer. Therefore, the identification of specific biomarkers and potential therapeutic target molecules for hematogenous recurrence is required to improve the outcomes of these patients. Here, transcriptome and bioinformatics analyses were conducted to uncover candidate molecules differentially expressed in patients with hematogenous recurrence of gastric cancer. One potential candidate identified was asialoglycoprotein receptor 2 (ASGR2) and small interfering RNA (siRNA) experiments were conducted to determine the effect of manipulating ASGR2 expression has on cell phenotypes...

Bhavya B Vendra, Esra Roan, John L Williams
The physis, or growth plate, is a layer of cartilage responsible for long bone growth. It is organized into reserve, proliferative and hypertrophic zones. Unlike the reserve zone where chondrocytes are randomly arranged, either singly or in pairs, the proliferative and hypertrophic chondrocytes are arranged within tubular structures called chondrons. In previous studies, the strain patterns within the compressed growth plate have been reported to be nonuniform and inhomogeneous, with an apparent random pattern in compressive strains and a localized appearance of tensile strains...

Episodic memory formation is considered a genuinely hippocampal function. Its study in rodents has relied on two different task paradigms, i.e. the so called "what-where-when" (WW-When) task and "what-where-which" (WW-Which) task. The WW-When task aims to assess the memory for an episode as an event bound into its context defined by spatial and distinct temporal information, the WW-Which task lacks the temporal component and introduces, instead, an "occasion setter" marking the broader contextual configuration in which the event occurred...

This paper presents a method to utilize the growth properties of anodic alumina possessing self-formation characteristics to fabricate a nano-textured microstructure and also introduces an application technique of the proposed method. The growth rate of anodic alumina, fabricated on aluminum surfaces, has a strong dependence on the intensity of the applied current density or electric field. The uniformity of the thickness of anodic alumina is determined by its electrical distribution characteristics. Accordingly, microscale structures can be fabricated using the growth rate deviation of anodic alumina...

The macrophage inducible C-type lectin (Mincle) is a pattern recognition receptor that recognises trehalose dimycolate (TDM), and trehalose dibehenate (TDB) and related trehalose diesters, and thus represents a promising target for the development of vaccine adjuvants based on the trehalose glycolipid scaffold. To this end, we report on the synthesis of a series of long-chain α-branched, β-modified trehalose monoesters and diesters to explore how glycolipid structure affects signalling through Mincle. Key steps in our synthetic strategy include a Fráter-Seebach α-alkylation to install the C20 aliphatic lipid on a malic acid derivative, and the formation of a β, γ-epoxide as an intermediate from which modifications to the β-position of the lipid can be made...

The hydrogel is considering as functional substrates for three-dimensional (3D) environment mimicking the native tissue in vitro. To get the cell or tissue culture result in different stiffness, researchers are used separate gel at the different time. Sometimes these results are manipulated by surrounding environment. To overcome this, we prepared a single hydrogel with different young modulus using a 3D printed mold and cell culture and tissue culture was performed to check the functional capacity. In this proposed device we successfully produced a multi properties agarose hydrogel on a single platform...

We survey structure and electronic properties of the family of higher trifluoromethylated C70(CF3)n molecules with n=14, 16, 18, and 20. Twenty two available compounds, of which thirteen are newly obtained and characterized, demonstrate broad diversity of π-system topologies, having enabled us to study the interplay between the CF3 addition pattern and the electronic properties. UV-vis spectroscopic and cyclic voltammetric studies demonstrate importance of the exact addition pattern rather than the plain number of addends...

De novo assembly of contractile myofibrils begins with the formation of premyofibrils where filaments of non-muscle myosin (NM II), and actin organize in sarcomeric patterns with Z-Bodies containing muscle-specific alpha-actinin. Interactions of muscle specific myosin (MM II) with NM II occur in a nascent myofibril stage that precedes the assembly of mature myofibrils. By the final stage of myofibrillogenesis, the only myosin II present in the mature myofibrils is MM II. In this current study of myofibril assembly, the three vertebrate isoforms of NM II (A, B, and C) and sarcomeric alpha-actinin, ligated to GFP family proteins, were coexpressed in avian embryonic skeletal and cardiac muscle cells...

Groundbreaking research done in the area of nanolithography makes it a versatile tool to produce nanopatterns for a broad range of chemical surface functionalization or physical modifications. We report for the first time an organocatalytic scanning probe nanolithography (o-cSPL) approach. Covalent binding of an organocatalyst on the apex of an atomic force microscope (AFM) tip gives way to a system that allows the formation of locally defined acylated-alcohol patterns on self-assembled monolayers (SAMs). With resolutions comparable to those of other cSPL methods, this first example of o-cSPL holds promise for future applications of bottom-up nanolithography set-ups employing this novel technique...
