Effect of Core Stability Exercises on Primary Dysmenorrhea and Muscular Fitness Indices in Teenage Girls

Purpose: The aim of this study was to determine the effect of core stability exercises on physical fitness of core muscles and primary dysmenorrhea inteenage girls. Methods: Participants of the study included 30 teenage girls with primary dysmenorrhea. Participants were assigned into either the exercise group (n=15) or control (n=15) group randomly. All subjects completed the Menstrual Symptom Questionnaire (MSQ) to measure symptoms of dysmenorrhea. Abdominal muscle endurance, balance and trunk flexibility of participants were measured respectively by sit up, one leg stance and Wels tests. Measurements were performed before and after the exercise period. The exercise group performed core muscle exercises for 8 weeks, 3 days a week. During this period control group did not participate in any kind of exercises. Analysis of variance with repeated measures and Pearson correlation tests were used for data analysis. Results: The result showed that core muscle exercises reduced dysmenorrhea symptoms (p=0.001), increased endurance of abdominal muscles (p=0.001), and flexibility (p=0.04) in exercise group. However, core muscle exercises did not change balance significantly (p>0.05). Dysmenorrhea changes were negatively related to physical fitness changes (r=0.55, p=0.002). Conclusion: Core muscle exercises can be used as a treatment to reduce the severity of dysmenorrhea which may be associated with increasing core muscle fitness indices.
Perspectives of Alopecia behind the Regulation of Foxn1 Gene Exposes the Human Nude Phenotype

The hair follicle (HF) is remarkable for its dynamic structure and one of the most promi- nent mini organs of the skin. The most visible end product formed by the hair follicle known as “hair shaft”- a tissue with a highly keratinized protein. Therefore, alopecia or baldness issue largely depends on the equilibrium between keratinocyte growth and differentiation of the HF. However, molecular nature in mice, rats, and humans, loss of transcription factor Foxn1 the keratinization processes is significantly impaired. Hence, this nude gene lack of function makes very similar hair pattern baldness in both human and nude mice (Foxn1nu/Foxn1nu). Thus highlighting the usefulness of mouse mutants and mouse genomics as a research tool for better molecular controls of human hair biology. To enhance research efforts of Foxn1 target gene regulation and the pharmaco logical manipulation of the nude phenotype are important open questions for promising research strategies related with Foxn1 biology. Taken together these issues may open the discovery of the investigative dermatology that promises the controls of epithelial differentiation in mammalian skin.
Face Tells the Truth: How Male Entrepreneur's Facial Masculinity Predicts New Venture Corporate Illegality

Prior research studies how chief executive officers’ (CEOs’) demographic characteristics, such as gender and age, impact firm unethical behaviors. However, the effect of CEOs’ biological traits on corporate illegality is not fully known. Grounded in the approach/inhibition theory of power, this article analyzes whether and how one of male entrepreneurs’ most obvious genetically determined biological traits, facial masculinity, predicts the corporate illegality of new ventures. Biological traits are mainly genetically determined. They not only shape an individual's psychological process, but also impact behaviors. Recently, scholars repeatedly call for incorporating entrepreneurs’ biological traits into entrepreneurship research. Based on a sample of Chinese firms listed in the growth enterprise market from 2010 to 2016, we identify and quantify male entrepreneurs’ facial masculinity with the artificial intelligence facial recognition technology Face++. We find a positive relationship between male entrepreneurs’ facial masculinity and new venture corporate illegality. Moreover, we explore the moderating role of individual differences (personal accountability) and social factors (social instability). These factors decrease the likelihood of male entrepreneurs with more facial masculinity to engage in new ventures corporate illegality. Although the facial masculinity of firm leaders may benefit firms by improving firm performance, our results show that there is a need to consider this stably biological trait when predicting unethical behaviors among new ventures.
Assessing Ethnobiological Use of Spices and Condiment in Prepared Dishes in Bahir Dar City Market, Bahir Dar ,Ethiopia: Ethnobiological Study

Background : Spices and condiments are substances added to foods to enhance aroma and taste.Traditional preparation of spice and condiments increase food flavors and give value for indigenous knowledge. Methods: One houndred sixty nine informants were selected by using random sampling technique. Semistractured interview and prepared questionare were employed to collect pertinent data on the local use of spice and condiments.The data obtained were analyzed by using analytical tools commonly ordered in ethnobiologiacal studies like preference ranking, direct matrix ranking and pairedwise comparestion. Result: Twenty four species of spice were found in the market. Eight condiments were identified in routinely prepared dishes. From the result of Paired comparison Allium sativum scores the highest use value in the preparation of spice and condiments. Preference ranking result also indicated that Red pepper is the most preferred condiment by the inhabitant of local community. This study also indicated that the indigenous knowledge in the preparation of spice vary with age groups with the elder more knowledgeable than youngsters. The indignous knowledge also under threat as the young are not interested in the domestic activities. Conclusion: There is knowledge limitation (deterioration) in the younger generation.The younger generation keep to learn, preserve and maintain their ancestral wisdom with respect to the indigenous use of spice and condiments in the local resident.

Improving Latency Analysis for Flexible Window-Based GCL Scheduling in TSN Networks by Integration of Consecutive Nodes Offsets

Time-sensitive networking (TSN) is an upcoming set of Ethernet standards designed for real-time and safety-critical Internet-of-Things (IoT) applications in automotive, aerospace, and industrial automation domains. With the combination, complexity, and flexibility of flow control mechanisms in TSN connected systems, the performance analysis for mixed-critical messages is becoming a difficult challenge. The flexible window-based gate control list (GCL) scheduling model has been proposed as a relaxation to assumptions on frames-to-window allocation, mutually exclusive gates opening, and scheduled end systems and switches, which offers more flexibility in the configuration of GCLs. In this article, we are interested in providing a reliable verification method based on the network calculus theory to drive GCL configurations for TSN networks. To the best of our knowledge, this is the first performance analysis method suitable for the general flexible window-based GCLs in entire TSN networks, by reflecting the relative positional relationships of windows for same priority queues on consecutive nodes and constructing the window limitations into the shaper curve, in order to reduce the pessimism of the latency bounds. We validate the proposed method through Industrial IoT synthetics test cases and two large realistic cases, showing the significant reduction in pessimism on delay bounds, and the correctness and scalability by comparing with results from the previous work and simulation results.
Effect of Using Soaking, Germination and Cooking for Common Vetch Vicia Sativa Seeds on Growth Performance of Common Carp Cyprinus carpio L.

This investigation was carried out to utilize common vetch Viciasativia in formulating diets for common carp Cyprinuscarpio L. with initial weights 69.28 g/fish had been distributed randomly over nine experimental diets, with three replication for each. The fish have been fed for 56 days on experimental diets which contained 30% and 45% of common vetch of total diets instead of 55% and 80% of soybean meal. Fish fed at diets contain that treated with soaking in water for 24 Hrs. (diet 2 and 3), 48 Hrs. (diet 4 and 5), soaking in water (48Hrs.) then germinated for 72 Hrs. (diet 6 and 7) and the last cooked (diet 8 and 9). The statistical analysis of data showed that there were no significant differences (P>0.05) among fed fish diet at 3rd , 4th and 8th in total weight gain ,weight daily gain ,relative growth rate ,specific growth rate ,and protein efficiency ratio with control diet. Where as the best food conversion ratio was obtained when fish fed at diet 2nd , 3rd and 4th which significantly differ (P> 0.05) for control and other diets.
The spatial ecology of adult Labeobarbus marequensis and their response to flow and habitat variability in the Crocodile River, Kruger National Park

The spatial movement of Labeobarbus marequensis was evaluated by attaching radio transmitters to 16 adult fish and tracking them from August 2009 to July 2012 in the Crocodile River, Kruger National Park, South Africa. Monthly monitoring surveys acquired 1 620 manual and 64 499 remote observations. Results showed adult L. marequensis did not participate in any migrations. Habitat preferences for L. marequensis were deep runs and fast glides, and there was disproportionately high use of submerged boulders as a cover feature. Tagged individuals also made use of rapids and pools, however, avoided shallow sandy slow glides. There was a reduced activity response of tagged individuals to rapid changes in water discharge. Continued changes in flow and instream habitat might threaten the Crocodile River population. Additional investigation into the effect of altered flows and associated habitat availability to the movement of L. marequensis is needed to better understand the effect of anthropogenic water resource use on L. marequensis in the Crocodile River.
SILVER DOPING EFFECT ON ANTIBACTERIAL ACTIVITIES OF CADMIUM OXIDE NANOPARTICLES

Cadmium oxide nanoparticles were synthesized with cadmium chloride and sodium hydroxide as starting materials using the co-precipitation method. This study analyses the enhancement of antibacterial activities of cadmium oxide on the addition of silver. The antibacterial activity was carried out in-vitro against two kinds of bacteria: grampositive bacteria, Micrococcus Luteus and gram-negative bacteria, Escherichia Coli using the well diffusion method. The tested concentration range of cadmium oxide nanoparticles was 100m/mL, 150m/mL, 200m/mL. The results showed that cadmium nanoparticles had an inhibitory effect against both pathogenic bacteria with a zone of inhibition (18, 20, 24 mm) for Micrococcus Luteus and (14, 16, 18 mm) for Escherichia Coli. The antibacterial effect was more prominent against the high concentration of nanoparticles. Cadmium oxide nanoparticles with silver as a dopant excel in different potential applications.
Acquirer’s Absorptive Capacity and Firm Performance: The Perspectives of Strategic Behavior and Knowledge Assets

In this study, we underline the importance of the relationship between absorptive capacity and an acquiring firm’s post-merger performance following the acquisition of a target firm’s knowledge through cross-border mergers and acquisitions (CBMAs). We analyzed CBMAs between developed countries to highlight how realized absorptive capacity plays a crucial part in a firm’s achievement of CBMA sustainability. Using United States CBMA transactions with other developed countries during 2000–2014, our findings suggest that an acquiring firm’s greater absorptive capacity leads to better post-merger performance. More interestingly, compared to for domestic M&As, the direct effect between absorptive capacity and post-merger performance was found to be more positively related in CBMA transactions, even when we applied propensity-score matching (PSM) and Heckman’s selection model to the same estimation. In addition, we introduce four moderating variables that could either intensify or lessen a firm’s effort to seek external knowledge for organizational growth. In terms of an acquiring firm’s strategic behavior, we find that paying in cash and past CBMA experiences positively influence a firm’s post-merger performance. For a target firm’s knowledge assets, we show that when a target firm possesses more strategic assets, they reinforce the acquiring firm’s post-merger performance, and when the target firm is in a high-tech industry, the acquiring firm’s post-merger performance is weakened. Our study contributes to the CBMA literature by incorporating the concept of a knowledge-based view and by empirically testing the different effects of absorptive capacity between domestic M&A and CBMA and how both strategic behavior and a target firm’s knowledge assets affect a firm’s post-merger performance related to CBMA sustainability.
When Does Board Diversity Benefit Shareholders? Strategic Deadlock as a Commitment to Monitor

We ask when and how a diverse board can benefit shareholders. Board diversity may be value-increasing even if some directors have agendas that are not perfectly aligned with shareholders' interests. Diversity commits the board to a high information standard because directors with opposing agendas are deadlocked unless they have persuasive information in support of the optimal course of action. Since deadlock is costly, diversity strengthens directors' incentives to gather information ex ante, which raises expected firm value. Diversity is more likely desirable if the firm's information environment is poor and if directors' opposing agendas are accompanied by sufficiently strong incentives for value maximization. However, if directors cannot credibly communicate their information, a homogeneous board dominates a diverse board.
Functional network dynamics in a neurodevelopmental disorder of known genetic origin

Cognitive processing depends on the temporal co-ordination of functional brain networks. This fundamental aspect of neurophysiology potentially bridges the genetic regulation of neuronal activity and developmental cognitive impairments. We investigated brain network dynamics in a neurodevelopmental disorder of known genetic origin, by comparing individuals with ZDHHC9-associated intellectual disability to individuals with no known impairment. We used Hidden Markov Modelling on magnetoencephalography (MEG) data, at rest and during auditory oddball stimulation, to characterise transient network dynamics. At rest, network dynamics distinguished the groups, with ZDHHC9 participants showing longer state activation. Crucially, ZDHHC9 gene expression levels predicted the group differences across networks, supporting an association between molecular pathology and neurophysiology. In contrast, network dynamics during auditory oddball stimulation did not show this association. We demonstrate a link between brain network dynamics and regional gene expression, and present a valuable method for understanding the real-time neural mechanisms linking genetic variation to cognitive difficulties.

A preliminary investigation of the entomofauna composition of forensically important necrophagous insects in Al-Madinah Al-Munawwarah region, Kingdom of Saudi Arabia

ABSTRACT The key role in forensic entomology is the study of entomofauna composition through species identification, succession, colonization, and developmental rate. In this study, rabbit carcasses were used as a model to identify the forensic insect species in Al-Madinah Al-Munawwarah, Saudi Arabia. The appearance and succession of these insects can help in the estimation of the minimum postmortem interval (mPMI) and in many other applications in this region. During the decomposition process, the most important forensic insects observed were from the orders Diptera and Coleoptera. Seven species in five families of Diptera and four families of Coleoptera were identified. The most abundant species in the area that colonized the carcasses were Chrysomya albiceps Widemann (Diptera: Calliphoridae) and Dermestes maculatus De Geer, which can be used for mPMI estimations. This study was the first conducted in Al-Madinah Region to provide a qualitative assessment of forensically important necrophagous species in this region.
The Collateral Damage of Sodium Nitrates and Alleviating Properties of Vitamin C on Thyroid Gland of Adult Male Albino Rats: Toxicological, Histological and Ultrastructural study

Introduction: In the recent years, a considerable attention has been paid to the problem of nitrates due to their intensive use as agricultural fertilizers which reach to humans and animals by different routes. Purpose: To validate the toxic effects of nitrates in a short-term experiment (60 days) on thyroid gland and the possible ameliorative effect(s) of vitamin C. Materials and methods: Thirty two adult male albino rats were divided into four groups: group I (control) received distilled water, group II received 500mg⁄kg vitamin C, group III received 130mg/kg sodium nitrates (NaNO3) and group IV received 130mg/kg NaNO3 plus 500mg⁄kg vitamin C. All supplementations were taken as oral single dose daily for 60 days. At the end of experiment, blood samples were subjected to hormonal assay (T3, T4 and TSH serum levels). Also, thyroid glands' specimens were prepared for the optical and electron microscopic examination. Results: IThe biochemical analyses showed a significant decrease in serum T3 and T4 and a significant increase in TSH. II-Light microscopic examination of nitrates treated group revealed disturbed thyroid architecture in the form of heterogeneous poorly developed follicles. Enlarged deformed follicles with scanty vacuolated colloid, degenerative empty follicles and some fused follicles with exfoliated cells filled their lumen were observed. III-Electron microscopic examination showed stratification of follicular epithelial cells. Most of the follicular cells appeared with irregular nuclei, dilation of rER, many vacuoles and an apparent number of lysosomes. Also hypertrophy and hyperplasia of parafollicular-C cells were observed. An improvement of thyroid gland’s structure, ultrastructure and function was observed in vitamin C added group. In conclusion: This study concluded that nitrate is a thyroid gland disruptor via a mutual interdependence between the follicular, parafollicular and intra-thyroidal mast cells. The supplementation of vitamin C showed beneficial effects upon biochemical and patho-morphological alterations, developed in thyroid gland following exposure to toxic doses of nitrates. So, the recommendations are limitation of sodium nitrates uses, encourage dietary intake of vitamin C and routine analysis of thyroid function in the most nitrates' contaminated areas.
Comparison of choroidal thickness in normal eyes and different ocular pathologies
 in a Brazilian population

Objective : To evaluate the choroidal thickness (CT) in healthy Brazilian subjects using spectral-domain optical coherence tomography (SD-OCT) and to compare with choroidal thickness measured in Brazilian patients with diabetic macular edema (DME), neovascular age-related macular degeneration (AMD) and high myopia. Methods : A retrospective analysis of spectral domain optical coherence tomography (SD-OCT) images of 181 Brazilian subjects. A total of 74 eyes were included in the normal control group, 50 eyes in the nvAMD group, 44 eyes in the DME group and 13 eyes in the high myopia group. CT was measured from the posterior edge of the retinal pigment epithelium (RPE) to the choroid/sclera junction at the fovea and at 500 μm intervals temporal and nasal to the fovea. All measurements were performed by two independent observers and were averaged for analysis. The statistical analysis and comparison were performed using Mann Whitney (unpaired t-test). Results : Seventy-four eyes from 74 patients with a mean age of 51.4 years were analyzed in the normal group with a mean nasal, subfoveal and temporal choroidal thickness measurements were 301.30 ± 12.86 μm, 311.61 ± 12.62 μm and 309.28 ± 12.28 μm respectively. All groups with disease demonstrated a statistically significant choroidal thinning when compared with matched-aged normal eyes. The mean reduction in the nvAMD group compared to normal were 60.65 μm nasally, 59.77 μm temporally and 56.59 μm at subfoveal position. In the DME group, the subfoveal reduction was 51.10 μm, 63.03 μm and 46.30 μm, nasally and temporally. The patients with high myopia presented the greatest reduction in CT compared to normal eyes, with a mean reduction of 159.9 nasal, 159.98 subfoveal and 154.65 at temporal. Conclusions : The present study evaluated choroidal thickness in Brazilian subjects, with intense miscegenation. The results demonstrated a statistically significant decrease of the choroidal thickness in all subtypes of chorioretinal disease. The small sample size in this study was a limitation. Additional research with a larger study population to better understand these findings. laser therapy and previous pars plana vitrectomy.
The lichen family Teloschistaceae in the Altai-Sayan region (Central Asia)

Within the Altai-Sayan region, we identified 103 species of Teloschistaceae from 1193 field records supported by herbarium vouchers. The recorded species belong to the subfamilies Xanthorioideae (46 species in 14 genera) and Caloplacoideae (57 species in 17 genera); Teloschistoideae is absent. We divided the 194 surveyed localities into four categories: arid alpine, arid non-alpine, humid alpine, humid non-alpine. Each category has a specific lichen composition and a typical combination of traits. Humid non-alpine localities are mostly inhabited by broadly distributed boreal-montane species; humid alpine sites by arctic-alpine lichens; arid non-alpine habitats are preferred by xerophilous Eurasian species and arid alpine sites by xerophilous Central Asian species with (presumably) large geographic ranges in dry continental Asia. Some arid alpine species have a thick crustose thallus with a very thick medulla and cortex; this morphological trait is confined to the Central Asian group of lichens and is absent from other climatic regions, such as arctic, boreal or oceanic Eurasia. We compared species diversity in the Altai-Sayan region with the Alps. Both regions differ in species and generic composition and the richness is higher in the latter. Taxonomy: Caloplaca fluviatilis is newly described. New combinations are Pachypeltis insularis, P. pachythallina, P. phoenicopta and Variospora sororicida. Two of Magnusson’s names are newly synonymized: Caloplaca infestans with Pachypeltis intrudens and Caloplaca kansuensis with C. bicolor. In addition to 22 known genera, we define, provisionally, 9 groups of species that may merit recognition as genera. Caloplaca epithallina is provisionally placed in Shackletonia, but we do not formally publish a new combination. Lichenicolous Pachypeltis phoenicopta and Variospora sororicida are less host-specific than originally thought. Floristics: Caloplaca pratensis is new to Eurasia, Caloplaca helygeoides (= C. diphyodes auct.), C. monacensis and C. soralifera are new to Asia. 12 species are new to Russia, 9 new to Siberia, 9 new to China, 2 new to Kazakhstan, and 2 new to Xinjiang. Outside the studied region Pachypeltis phoenicopta is new to Europe (Spain, Sierra Nevada) and we report the first reliable record of Pachypeltis insularis from Greece (Mt Olympus).
