The article is focused on finding the possibility of the controlled orientation of fibres in fibre reinforced concrete constructions. This is because the controlled orientation of the fibres can contribute to the improvement of some properties of fibre reinforced concrete. The research is based on the experimental investigation of orientation control-rotation of fibres in a transparent matrix representing concrete replacement. From the conceptual model, the article continues with experimentation, data analysis and comparison of conclusions...

Oral-nasal mucosal immunity plays a crucial role in protecting the body against bacterial and viral invasion. Safe probiotic products have been used to enhance human immunity and oral health. In this study, we verified the beneficial effects of mixed viable probiotic tablets, consisting of Lactobacillus salivarius subsp. salicinius AP-32, Bifidobacterium animalis subsp. lactis CP-9, and Lactobacillus paracasei ET-66, and heat-killed probiotic tablets, consisting of L. salivarius subsp. salicinius AP-32 and L...

Wheat plants showing yellowing and mosaic in leaves and stunting were collected from wheat fields in Henan Province, China. Analysis of these plants by transmission electron microscopy showed that they contained two types of filamentous virus-like particles with a length of 200-500 nm and 1000-1300 nm, respectively. RNA-seq revealed a coinfection with wheat yellow mosaic virus (WYMV) and an unknown wheat-infecting virus. The genome of the unknown virus is 8,410 nucleotides long, excluding its 3' poly(A) tail...

To identify the viruses in tree peony plants associated with the symptoms of yellowing, leaf rolling, stunted growth, and decline, high-throughput sequencing of small RNA and mRNA was conducted from a single symptomatic plant. Bioinformatic analyses and reconstruction of viral genomes indicated mixed viral infections involving cycas necrotic stunt virus (CNSV), apple stem grooving virus (ASGV), lychnis mottle virus (LycMoV), grapevine line pattern virus (GLPV), and three new viruses designated as peony yellowing-associated citrivirus (PYaCV, Citrivirus in Betaflexiviridae), peony betaflexivirus 1 (PeV1, unclassified in Betaflexiviridae), and peony leafroll-associated virus (PLRaV, Ampelovirus in Closteroviridae)...

BACKGROUND: Tuberculosis is a chronic infection caused by Mycobacterium tuberculosis (M.tb), which needs proper macrophage activation for control. It has been debated whether the co-infection with helminth will affect the immune response to mycobacterial infection. OBJECTIVE: To determine the effect of sequential co-infection of Heligmosomoides polygyrus (H.pg) nematodes and M.tb on T cell responses, macrophages polarization and lung histopathological changes. METHOD: This study used 49 mice divided into 7 treatment groups, with different sequence of infection of M...

Twist grain boundary (TGB) phases exhibiting highly frustrated and complex liquid crystal structures have aroused enormous interest because of their close resemblance to superconductors. The remarkable experimental demonstration of their occurrence by Goodby and co-workers paved the way for developing new research endeavors. However, of the several genuine concerns associated with these intriguing structures, their temperature range has been challenging. In this communication, we report the occurrence of the TGB phase with smectic C* blocks (TGBC*) over a vast, unprecedented thermal range of ∼170 °C in a newly synthesized chiral dimer derived from cholesterol...

BACKGROUND: It is known that serum thyroglobulin (TG) can increase after fine-needle biopsy of thyroid nodules. We aimed to determine whether TG is increased after ultrasonography (US)-guided fine needle capillary biopsy (FNC) of suspicious cervical lymph nodes (LNs) in thyroidectomised patients and investigate the possible association between change in TG and cytology results. MATERIAL AND METHODS: Data of 188 patients who underwent FNC of suspicious cervical LNs were retrospectively evaluated...

Obtaining homochirality from biased symmetry-breaking of self-assembly in achiral molecules remains a great challenge due to the lack of ingenious strategies and controlling their handedness. Here, we report the first case of biased symmetry breaking from achiral platinum (II) liquid crystals which self-organize into an enantiomerically enriched single domain without selection of handedness in twist grain boundary TGB [ *] phase. Most importantly, the chiral control of self-organization can be achieved by using above the homochiral liquid crystal films with determined handedness (P or M) as a template...

BACKGROUND: Before the deposition of amyloid-beta plaques and the onset of learning memory deficits, patients with Alzheimer's disease (AD) experience olfactory dysfunction, typified by a reduced ability to detect, discriminate, and identify odors. Rodent models of AD, such as the Tg2576 and APP/PS1 mice, also display impaired olfaction, accompanied by aberrant in vivo or in vitro gamma rhythms in the olfactory pathway. However, the mechanistic relationships between the electrophysiological, biochemical and behavioral phenomena remain unclear...

We conducted a systematic review of anti-seizure medications (ASMs) and their efficacy for the control of focal to bilateral tonic-clonic seizures (FBTCS). FBTCS, especially when nocturnal, are recognized as one of the major risk factors for Sudden Unexpected Death in Epilepsy (SUDEP). We searched different online databases for all the randomized, double-blinded, and placebo-controlled clinical trials of ASMs that were FDA-approved after 1990 and that reported specifically on the reduction in FBTCS; when possible, this was compared to reduction in focal impaired awareness (FIA) seizures...

This review article elucidates the differential diagnostics of malignant and benign joint tumors, pseudotumors of the joints and the peri-implant tissue, which are rare but important entities in rheumatology and orthopedic rheumatology. The tissue of origin includes the synovium, peri-implant tissue, peri-articular fibrous tissue and peri-articular osseous tissue. Pseudotumors can be viewed as independent but heterogeneous entities. These are essentially manifested as tumor-like depositions of crystals, calcareous deposits, vascular malformations, ectasia of the synovia and joint capsule tissue and pseudocysts...

Most plant viruses code for movement proteins (MPs) targeting plasmodesmata to enable cell-to-cell and systemic spread in infected plants. Small membrane-embedded MPs have been first identified in two viral transport gene modules, triple gene block (TGB) coding for an RNA-binding helicase TGB1 and two small hydrophobic proteins TGB2 and TGB3 and double gene block (DGB) encoding two small polypeptides representing an RNA-binding protein and a membrane protein. These findings indicated that movement gene modules composed of two or more cistrons may encode the nucleic acid-binding protein and at least one membrane-bound movement protein...

Background: Older people with chronic musculoskeletal pain are at risk of falls. This study aimed to investigate the effects of exergaming on pain and postural control in older people with chronic musculoskeletal pain. Secondary outcomes were technology acceptance, flow experience, perceived physical exertion, expended mental effort and heart rate. Methods: Fifty four older adults (age: 71 ± 5 years) with chronic musculoskeletal pain were randomised into 2 groups...

Plant virus transport complementation is classically observed as a helper virus allowing another virus to regain cell-to-cell or systemic movement through a restrictive host plant (Malyshenko et al., 1989). The complementation effect is usually studied by observing virus infection after co-infection or super-inoculation of the helper virus. We herein demonstrate the utility of functionally deficient viral vectors as tools to determine the contribution of individual viral genes to plant viral transport complementation...

In this study, a set of duplex reverse transcription (RT)-PCR-mediated high resolution DNA melting (HRM) analyses for simultaneous detection of potato mop-virus (PMTV) and its protist vector, Spongospora subterranea f.sp. subterranea (Sss), was developed. The infestation of soil by PMTV was detected by using a tobacco-based baiting system. Total RNA extracted from the soil led to successful RT-PCR gel-electrophoresis detection of both PMTV and Sss. To facilitate more efficient detection, newly designed primer pairs for PMTV RNA species (i...

Nine genera of viruses in five different families use triple gene block (TGB) proteins for virus movement. The TGB modules fall into two classes: hordei-like and potex-like. Although TGB-mediated viral movement has been extensively studied, determination of the constituents of the viral ribonucleoprotein (vRNP) movement complexes and the mechanisms underlying their involvement in vRNP-mediated movement are far from complete. In the current study, immunoprecipitation of TGB1 protein complexes formed during Barley stripe mosaic virus (BSMV) infection revealed the presence of the γb protein in the products...

The aim of the present study was to investigate various aspects of tiagabine (TGB) effectiveness in Bulgarian patients with drug-resistant epilepsy. This open, prospective study recruited the patients with epilepsy attending the Clinic of Neurology at the University Hospital of Plovdiv, Bulgaria. The patients completed diaries about the seizure frequency, severity, and adverse events. There were regular documented visits at 3 or 6 months during the first year of treatment with TGB and at 6 months or 1 year afterwards, with dynamic assessment of seizure frequency, severity, adverse events, and EEG recordings...

Tiagabine hydrochloride (TGB) is a clinically frequently-used drug for anti-convulsion and reducing epileptic frequency. Over administration of TGB could bring about adverse effects, such as speech disorder, depression and even suicidal tendencies. Therefore, accessible and sensitive assay for analysis of TGB becomes an urgent front-burner towards guiding clinical medication. Here, we present the first report on fluorescence turn-on detection of TGB in urine testing. In this protocol, a fluorescent dye, perylene tetracarboxylic acid imide derivative (PTAI), is found specifically occupies the sudlow site II of human serum albumin (HSA) and displays a new phenomenon of binding-induced quenching (BIQ)...

Approximately 30-40% of patients with drug-resistant epilepsy (DRE) who underwent vagus nerve stimulator (VNS) implantation achieve above 50% reduction in seizure frequency. VNS proves effective in reducing frequency of seizures in DRE patients, when combined with antiepileptic drugs (AEDs). This raises a question whether improvement of clinical parameters is achieved with VNS only or relies on combined therapy with AEDs. The aim of the study was the analysis of impact of VNS on clinical recovery of patients with DRE and the analysis of pharmacotherapy costs and drug regimen following VNS implantation in DRE patients...
