Profiling the Extent and Location of Pain in Migraine and Cervicogenic Headache: A Cross-sectional Single-Site Observational Study.

OBJECTIVES The primary aim was to quantify and compare the location and extent of pain in people with either episodic migraine, chronic migraine, or cervicogenic headache. A secondary aim was to examine the associations between pain extent and headache features, quality of life, and psychological distress for each headache type. DESIGN A cross-sectional, single-site, observational study. SETTING Headache outpatient clinic. SUBJECTS From a sample of 390 patients, 114 patients with migraine or cervicogenic headache (48 episodic migraine, 30 chronic migraine, 36 cervicogenic headache) were eligible for the study. METHODS Pain location and extent were determined using a novel approach for digital pain drawing acquisition and analysis. Headache features included intensity and history duration. Quality of life was measured using the SF-36 and psychological distress using the Hospital Anxiety and Depression Scale. RESULTS Overall, pain was most frequently reported in the frontal and temporal regions in patients with either episodic or chronic migraine, whereas pain was most frequent in the suboccipital region in patients with cervicogenic headache. A larger pain extent was moderately correlated with higher headache intensity (rs = 0.53, P = 0.003) and poorer quality of life (rs ranged from -0.36 to -0.40, P < 0.05) in patients with chronic migraine, whereas pain extent was associated with longer headache duration in those with cervicogenic headache (rs = 0.35, P = 0.04). No correlation was found between pain extent and psychological features for any headache type (P > 0.05). CONCLUSIONS Despite some differences, there was a large symptomatic overlap between headache types, highlighting the limitations of using pain location in the differential diagnosis of headache.
Cell Synchronization Enhances Nuclear Transformation and Genome Editing via Cas9 Enabling Homologous Recombination in Chlamydomonas reinhardtii

In Chlamydomonas reinhardtii, the model organism for eukaryotic green algae and plants, the processes of nuclear transformation and genome editing in particular are still marked by a low level of efficiency, and so intensive work is required in order to create and identify mutants for the investigation of basic physiological processes, as well as the implementation of biotechnological applications. In this work, we show that cell synchronization during the stages of the cell cycle, obtained from long-term cultivation under specific growth conditions, greatly enhances the efficiency of transformation and allows the identification of DNA repair mechanisms that occur preferentially at different stages of the cell cycle. We demonstrate that the transformation of synchronized cells at different times was differentially associated with nonhomologous end joining (NHEJ) and/or homologous recombination (HR), and makes it possible to knock-in specific foreign DNA at the genomic nuclear location desired by exploiting HR. This optimization greatly reduces the overall complexity of the genome editing procedure and creates new opportunities for altering genes and their products.
Sorafenib reduces steatosis‐induced fibrogenesis in a human 3D co‐culture model of non‐alcoholic fatty liver disease

Non‐alcoholic fatty liver disease (NAFLD) affects around 25% of the worldwide population. Non‐alcoholic steatohepatitis (NASH), the more progressive variant of NAFLD, is characterized by steatosis, cellular ballooning, lobular inflammation, and may culminate on hepatic stellate cell (HSC) activation, thus increasing the risk for fibrosis, cirrhosis, and HCC development. Conversely, the antifibrotic effects of sorafenib, an FDA‐approved drug for HCC treatment, have been demonstrated in 2D cell cultures and animal models, but its mechanisms in a NAFLD‐related microenvironment in vitro requires further investigation. Thus, a human 3D co‐culture model of fatty hepatocytes and HSC was established by culturing hepatoma C3A cells, pre‐treated with 1.32 mM oleic acid, with HSC LX‐2 cells. The fatty C3A/LX‐2 spheroids showed morphological and molecular hallmarks of altered lipid metabolism and steatosis‐induced fibrogenesis, similarly to the human disease. Sorafenib (15 μM) for 72 hours reduced fatty spheroid viability, and upregulated the expression of lipid oxidation‐ and hydrolysis‐related genes, CPT1 and LIPC, respectively. Sorafenib also inhibited steatosis‐induced fibrogenesis by downregulating COL1A1, TGFB1, PDGF, and TIMP1 and by decreasing protein levels of IL‐6, TGF‐β1, and TNF‐α in fatty spheroids. The demonstration of the antifibrotic properties of sorafenib on steatosis‐induced fibrogenesis in a 3D in vitro model of NAFLD supports its clinical use as a therapeutic agent for the treatment of NAFLD/NASH patients.
Dammarane Saponins of Gynostemma pentaphyllum MAKINO and Isolation of Malonylginsenosides-Rb1, -Rd, and Malonylgypenoside V

6"-Malonylginsenosides-Rb1, (6), -Rd (7) and 6"-malonylgypenoside V (8) were isolated from the fresh leaves of Gynostemma pentaphyllum selected from wild plants. It was found that the saponin content of dry leaves was markedly reduced because of decomposition of saponins, by intracellular glycosidases.
Habitat preference of the striped legless lizard: Implications of grazing by native herbivores and livestock for conservation of grassland biota

Across the globe, many species of reptile are threatened with extinction, with changes in grazing pressure as a significant factor in their decline. Few studies have investigated the role of native herbivores, yet studying natural grazers may provide insight into natural grazing regimes, not apparent in studies of domestic livestock. In this study, we investigate the habitat requirements of a threatened Australian grassland reptile, the striped legless lizard, Delma impar, in grasslands grazed by a native herbivore, the eastern grey kangaroo Macropus giganteus. Delma impar appears sensitive to habitat change resulting from altered grazing intensity, but a lack of information hinders implementation of appropriate grazing regimes. To address this gap, we investigated habitat preferences of D. impar at multiple spatial scales across a grazing gradient. We found that the occurrence of D. impar was not affected by the size of grassland remnants, but was negatively related to the density of native grazers. This result was likely a consequence of the negative effect of high grazing intensity on grass structural complexity, as the probability of encountering a D. impar was positively related to grass structural complexity at the fine scale (1 m2). We recommend that conservation efforts should avoid high intensity grazing (equivalent to > 1.3 kangaroos/ha), yet ensure enough grazing disturbance is maintained to promote the formation of complex grass structures. We also recommend that small floristically degraded and fragmented grassland habitat should be included in conservation efforts. These recommendations will likely benefit a number of faunal species in grasslands grazed by domestic and native grazers. Importantly, our data highlight the need for managing grazing regimes, even in environments dominated by native herbivores.
Automatic point cloud registration algorithm based on the feature histogram of local surface

In this paper, we present an efficient algorithm for point cloud registration in presence of low overlap rate and high noise. The proposed registration method mainly includes four parts: the loop voxel filtering, the curvature-based key point selection, the robust geometric descriptor, and the determining and optimization of correspondences based on key point spatial relationship. The loop voxel filtering filters point clouds to a specified resolution. We propose a key point selection algorithm which has a better anti-noise and fast ability. The feature descriptor of key points is highly exclusive which is based on the geometric relationship between the neighborhood points and the center of gravity of the neighborhood. The correspondences in the pair of two point clouds are determined according to the combined features of key points. Finally, the singular value decomposition and ICP algorithm are applied to align two point clouds. The proposed registration method can accurately and quickly register point clouds of different resolutions in noisy situations. We validate our proposal by presenting a quantitative experimental comparison with state-of-the-art methods. Experimental results show that the proposed point cloud registration algorithm has faster calculation speed, higher registration accuracy, and better anti-noise performance.
Salivary endocrine response following a maximal incremental cycling protocol with local vibration

The aim of this study was to compare the effects of vibration (Vib versus noVib) during a maximal graded cycling exercise on hormonal response, precisely on cortisol (C) and testosterone (T). Twelve active males (25 ± 5yrs; 181 ± 5cm; 80.7 ± 11.1kg) randomly performed two maximal incremental cycling tests on two separate days and at the same time of the day (09:00). The protocol consisted of incremental steps of 3 min duration performed on a PowerBIKETM that induces vibration cycling. The study was a repeated measures design and participants performed the test with and without vibration. Gas exchange and heart rate (HR) were continuously assessed and blood lactate (Bla) was recorded at the end of each incremental stage. Saliva samples were collected before and immediately after the test, and analysed for (C) and (T). The results show that C and T increased in both cycling conditions; however, the C’s magnitude of change was significantly higher by 83% after Vib cycling in comparison to the no Vib (p = 0.014), whereas the T’s magnitude of change were not statistically different between trials (p = 0.715). Vibration induced a decrease of the T/C ratio (p = 0.046) but no significant changes were observed following noVib (p = 0.476). As a conclusion, the investigation suggests that adding mechanical vibration to cycling may potentiate a catabolic exercise-induced state, which could have potential clinical implications in rehabilitation and injury treatment. Sport experts should take this message home to carefully plan the recovery process and time during training and competitions.
Advances in Antibody Preparation Techniques for Immunoassays of Total Aflatoxin in Food

Aflatoxin (AF) contamination is a major concern in the food and feed industry because of its prevalence and toxicity. Improved aflatoxin detection methods are still needed. Immunoassays are an important method for total aflatoxin (TAF) analysis in food due to its technical advantages such as high specificity, sensitivity, and simplicity, but require high-quality antibodies. Here, we first review the three ways to prepare high-quality antibodies for TAF immunoassay, second, compare the advantages and disadvantages of antigen synthesis methods for B-group and G-group aflatoxins, and third, describe the status of novel genetic engineering antibodies. This review can provide new methods and ideas for the development of TAF immunoassays.
Family Influences on Caries in Grenada

If high-conflict family environments are cariogenic across cultures, and can be studied in cultures where both these environments and cariogenic dental practices are particularly prevalent, this would afford the opportunity to examine how these two pathways of risk might interact, laying the stage for culturally competent, integrated prevention efforts. The first investigation involved qualitative data about perceptions of oral health and family stressors in Grenadian families with school-aged children. The second study used a questionnaire and observational data to assess relations among oral health behaviors, relationship satisfaction, parenting, and child behavior; it also included a pilot study of Motivational Interviewing. Most of the themes discussed in focus groups suggested overlap between U.S. and Grenadian parents; possible culture-specific issues were high prevalence of single-parent homes, normativity of physical discipline, less preventive dental care, and more fatalistic view of oral health outcomes. Significant associations were found between parent and child oral health behaviors, between child externalizing and internalizing behaviors, and between family variables (e.g., relationship satisfaction, child behavior) and oral health behaviors (e.g., parent flossing, child brush time). The results strongly support the need for research on the relations between family functioning and oral health to be embedded within culture.
Detection of Wx-mq Gene for Low-amylose Content by Tetra-primer Amplification Refractory Mutation System PCR in Rice

To improve the efficiency of selection for Wx-mq gene in breeding,we designed specific primers by tetraprimer Amplification Refractory Mutation System PCR(ARMS-PCR) method,according to the single nucleotide mutation in Wx-mq gene to analyze 12 rice varieties(or lines) and the F2 segregation population derived from the cross of low-amylose content variety Kanto 194(with Wx-mq gene) and normal variety Wuyujing 3(without Wx-mq gene). The results of PCR detection indicated that three genotypes including the homozygous genotype with Wx-mq,the homozygous genotype without Wx-mq and the heterozygous genotype could be clearly distinguished according to band types,and it was completely consistent with the result of phenotypic analysis.Therefore,as a simple and low-cost technique,the tetra-primer ARMS-PCR could be widely used to identify rice resources with Wx-mq gene and applied in molecular marker-assisted breeding.
CHAPTER 10:Magnetic Decoration and Labeling of Prokaryotic and Eukaryotic Cells

The majority of prokaryotic and eukaryotic cells can interact with a wide range of magnetic nano- and microparticles, molecular labels or paramagnetic cations. The magnetically modified cells usually maintain their viability and the presence of magnetic (nano)materials on their surfaces, in protoplasm or in intracellular organelles can provide additional functionalities. Magnetically responsive cells can be easily separated from complex samples using magnetic separators, can be monitored using magnetic resonance imaging or heated during magnetic-fluid hyperthermia. Available magnetization procedures are summarized in this chapter, as well as possible efficient applications of magnetically modified cells in cell biology, medicine, bioanalaysis, biotechnology and environmental technology, for example as whole-cell biocatalysts, parts of biosensor systems or adsorbents of organic and inorganic xenobiotics removal.
Choroid structure analysis following initiation of hemodialysis by using swept-source optical coherence tomography in patients with and without diabetes

We aimed to evaluate choroid structural changes using swept-source optical coherence tomography (SS-OCT) following hemodialysis initiation in diabetic and nondiabetic patients with end-stage kidney disease (ESKD). In this multicenter, prospective, cross-sectional study, diabetic (DM group; 30 eyes; 16 patients) and nondiabetic patients (NDM group; 30 eyes; 15 patients) with ESKD were evaluated after hemodialysis initiation. SS-OCT findings were analyzed using a manual delineation technique and binarization method before the first and last hemodialysis sessions, conducted approximately 2 weeks apart. Subfoveal choroidal thickness changes and mean large choroidal vessel layer thickness were significantly greater in the DM group (−13.3% ± 2.5% and −14.5% ± 5.2%, respectively) than the NDM group (−9.5% ± 3.1% and −9.2% ± 3.4%, respectively; p = 0.049 and p = 0.02, respectively). Binarized SS-OCT analysis revealed that the mean subfoveal choroidal area was significantly larger in the DM group (−21.9% ± 6.5%) than the NDM group (−17.2% ± 5.9%; p = 0.032). The change ratio in mean luminal area values was significantly greater in the DM group (−27.7% ± 8.7%) than the NDM group (−17.7% ± 5.8%; p = 0.007). The DM group exhibited substantial changes in the choroidal layer, possibly reflecting choroidal vascular disorders caused by diabetes.
Food Intake REstriction for Health OUtcome Support and Education (FIREHOUSE) Protocol: A Randomized Clinical Trial

Fire Department of New York (FDNY) rescue and recovery workers exposed to World Trade Center (WTC) particulates suffered loss of forced expiratory volume in 1 s (FEV1). Metabolic Syndrome increased the risk of developing WTC-lung injury (WTC-LI). We aim to attenuate the deleterious effects of WTC exposure through a dietary intervention targeting these clinically relevant disease modifiers. We hypothesize that a calorie-restricted Mediterranean dietary intervention will improve metabolic risk, subclinical indicators of cardiopulmonary disease, quality of life, and lung function in firefighters with WTC-LI. To assess our hypothesis, we developed the Food Intake REstriction for Health OUtcome Support and Education (FIREHOUSE), a randomized controlled clinical trial (RCT). Male firefighters with WTC-LI and a BMI > 27 kg/m2 will be included. We will randomize subjects (1:1) to either: (1) Low Calorie Mediterranean (LoCalMed)—an integrative multifactorial, technology-supported approach focused on behavioral modification, nutritional education that will include a self-monitored diet with feedback, physical activity recommendations, and social cognitive theory-based group counseling sessions; or (2) Usual Care. Outcomes include reduction in body mass index (BMI) (primary), improvement in FEV1, fractional exhaled nitric oxide, pulse wave velocity, lipid profiles, targeted metabolic/clinical biomarkers, and quality of life measures (secondary). By implementing a technology-supported LoCalMed diet our FIREHOUSE RCT may help further the treatment of WTC associated pulmonary disease.
Podravka and Slavonka Varieties of Pepper Seeds (Capsicum annuum L.) as a New Source of Highly Nutritional Edible Oil

The aim of this study was to evaluate Croatian pepper seed varieties (Podravka and Slavonka) as a new source of added value ingredients. Pepper seed is mostly considered a by-product. For the first time, the pepper (Capsicum annuum L.) seeds of the Slavonka and Podravka varieties were examined as the source material for oil production by the two methods of extraction: cold pressing (CP) and supercritical CO2 extraction (SC-CO2). Further, fatty acid profile, tocopherols, and sensory analysis of the oils were examined, as well as the chemical characteristics and antioxidant potential of seed flour. The antioxidant potential of pepper seed flour was different between varieties (Podravka 107 antioxidant unit (AU); Slavonka 70 antioxidant unit (AU)). The Podravka variety pepper seed oil has shown higher γ-tocopherol content (CP 80.1 mg/100 g; SC-CO2 extraction 65.3 mg/100 g) than the Slavonka variety (CP 65.3 mg/100 g; SC-CO2 extraction 16.0 mg/100 g). According to the obtained results, cold pressing (CP) would be a more favourable method for pepper seed oil extraction, taking into account sensory evaluation and nutritional quality. The pepper seed oil has potential for culinary application with a nutritional quality comparable to vegetable oils of a higher price class.
COVID‐19, smoking, vaping and quitting: a representative population survey in England

Abstract Aims To estimate (1) associations between self‐reported COVID‐19, hand‐washing, smoking status, e‐cigarette use and nicotine replacement therapy (NRT) use and (2) the extent to which COVID‐19 has prompted smoking and vaping quit attempts and more smoking inside the home. Design Cross‐sectional household surveys. Setting and participants A representative sample of the population in England from April to May 2020. The sample included 3179 adults aged ≥ 18 years. Measurements Participants who reported that they definitely or thought they had coronavirus were classified as having self‐reported COVID‐19. Participants were asked how often they wash their hands after returning home, before preparing foods, before eating or before touching their face. They were also asked whether, due to COVID‐19, they had (i) attempted to quit smoking, (ii) attempted to quit vaping and (iii) changed the amount they smoke inside the home. Findings Odds of self‐reported COVID‐19 were significantly greater among current smokers [20.9%, adjusted odds ratio (aOR) = 1.34, 95% confidence interval (CI) = 1.04–1.73] and long‐term (> 1‐year) ex‐smokers (16.1%, aOR = 1.33, 95% CI = 1.05–1.68) compared with never smokers (14.5%). Recent (< 1‐year) ex‐smokers had non‐significantly greater odds of self‐reported COVID‐19 (22.2%, aOR = 1.50, 95% CI = 0.85–2.53). Bayes factors indicated there was sufficient evidence to rule out large differences in self‐reported COVID‐19 by NRT use and medium differences by e‐cigarette use. With the exception of hand‐washing before face‐touching, engagement in hand‐washing behaviours was high (> 85%), regardless of nicotine use. A minority (12.2%) of quit attempts in the past 3 months were reportedly triggered by COVID‐19, and approximately one in 10 current e‐cigarette users reported attempting to quit vaping because of COVID‐19. Conclusions In England, current smokers and long‐term ex‐smokers appear to have higher odds of self‐reported COVID‐19 compared with never smokers in adjusted analyses, but there were no large differences between people who used nicotine replacement therapy or e‐cigarettes. Engagement in hand‐washing appears to be high, regardless of nicotine or tobacco use. A minority of past‐year smokers and current e‐cigarette users, respectively, report attempting to quit smoking/vaping due to COVID‐19.
Enhanced Antiproliferative Effect of Combined Treatment with Calcitriol and All-Trans Retinoic Acid in Relation to Vitamin D Receptor and Retinoic Acid Receptor α Expression in Osteosarcoma Cell Lines

The main objective of this study was to analyze changes in the antiproliferative effect of vitamin D3, in the form of calcitriol and calcidiol, via its combined application with all-trans retinoic acid (ATRA) in osteosarcoma cell lines. The response to treatment with calcitriol and calcidiol alone was specific for each cell line. Nevertheless, we observed an enhanced effect of combined treatment with ATRA and calcitriol in the majority of the cell lines. Although the levels of respective nuclear receptors did not correlate with the sensitivity of cells to these drugs, vitamin D receptor (VDR) upregulation induced by ATRA was found in cell lines that were the most sensitive to the combined treatment. In addition, all these cell lines showed high endogenous levels of retinoic acid receptor α (RARα). Our study confirmed that the combination of calcitriol and ATRA can achieve enhanced antiproliferative effects in human osteosarcoma cell lines in vitro. Moreover, we provide the first evidence that ATRA is able to upregulate VDR expression in human osteosarcoma cells. According to our results, the endogenous levels of RARα and VDR could be used as a predictor of possible synergy between ATRA and calcitriol in osteosarcoma cells.
