Abstract Postural balance plays an important role in high performance sports. The line between success and failure may be decided at such a small scale. In handball, postural balance may affect the accuracy of every technique that a played use, especially the throwing of the ball towards the goal. Our study aimed to identify the degree of influence that izometric effort has over the balance stance during a handball throw. Subjects: 210 1st year students from the Faculty of Physical Education and Sport, Babeș-Bolyai University from Cluj-Napoca, were involved in this study. The subjects were both male and female, with the ages between 18 and 21 years old, with and without former performance athlete background. Materials: We’ve conducted the balance test using the AMTI NETforce BP 400600 force platform and the actual isometric exercises were completed in the same laboratory. Two types of planks and a half-squat were used as the isometric exercises. Results: There was no significant statistical difference between the balance variables before and after isometric exercises while holding the ball in hand. There was a significant statistical difference between the displacement before and after for the position without the ball. Conclusion: There is no impact of the isometric effort over the balance stance while holding the handball ball in the throwing position. We’ve identified a strong relation between the isometric effort and the balance stance without the ball in hand.

Objectives: The aim of this study was to determine the influence of the sex of the therapist and of the athlete on the athlete’s current emotional state after a sports massage. The assumption was that the effect of a massage on the current mood was independent of the sex of the therapists or athletes. Background: Sports massages are an integral part of the support given to athletes during training or competition and are a commonly used method for promoting athletes’ physical and mental recovery. Few studies have measured the mental characteristics or even the nonspecific effects of sports massages. Sexual attraction or dislike are among the nonspecific effects of a treatment. Materials and methods: One hundred and sixty-eight high-performance male and female amateur athletes received a sports massage from 15 male and female trained therapists. The current emotional state of the athletes was measured before and after intervention using the BSKE-EA17 adjective scale, whose items can be assigned to five categories of the current emotional state. ANOVAs (analysis of covariances) were carried out to calculate the interactions between the sexes. Cohen’s d for similar group sizes and similar group variances were determined. Results: Neither the sex of the therapist nor the sex of the athlete had any influence on the mental effect of a sports massage. The only exception was when male athletes were treated by female therapists, where an increase in “elevated mood” was observed. Sports massages resulted in an increase in the responses in the categories “elevated mood” (d = 1.1) and “level of activation” (d = 0.3) and a decrease in the responses for “low mood” (d = 0.3), “level of deactivation” (d = 0.6) and “level of excitation” after the massage compared to before the massage (d = 0.9). Conclusions: Sports massages appear to increase the positive dimensions of the athletes’ current emotional state and reduce the negative dimensions. The self-reported mood changes from before the massage to after the massage were not influenced by other prognostic variables, including wait time, age of the athlete or the duration of the run. The results suggest that the specific effects of sports massages on the mental status are supported. Disregarding the aspect of the therapists’ sex, sports officials, trainers and athletes therefore can be more independent in the personnel planning of sports therapists.

Introduction: Analgesics are substances which work in various ways to relieve different types of pain experienced in the body. Non-prescription over-the-counter (OTC) drugs are widely used by patients to control pain and fever. Study Objective: To evaluate of knowledge, attitudes and practices about analgesic and their side effects. Methods: A cross-sectional study conducted during a period of three months from September to December 2017 in Rafha and Riyadh - Saudi Arabia on a random sample of 237 Saudi people, the data was collected by using a self-administered questionnaire in the Arabic language. Statistical analysis was done by using MS EXCEL using descriptive statistics and chi-square test. Results: A total of 237 participants out of 260 consented to be interviewed and completed the questionnaire with a response rate (91%). Their ages ranged between 18 years and 54 years with a mean (28) and standard deviation (7.9). Majority of participants were females (92%) and about two thirds (66%) were highly educated. A quarter of study participants (25%) do not read leaflet of analgesic before use. About one-fifth of respondents (20%) reported that they cannot stop taking analgesic even if the pain is mild. 12% and 36% of respondents always and sometimes, respectively, use more than one type of analgesic for pain relief. 10% of respondents reported the occurrence of side effects from analgesic. The respondents use analgesic mainly for headache (43%) and toothache (25%). The chronic disease for which participants take analgesic were mainly arthritis (39%) and migraine (30%). About three-quarters of respondents (74%) were aware that the use of analgesic is accompanied by side effects. The respondents believed that the reasons for analgesic misuse are that analgesic easily obtained without a medical prescription (40%) and there is no educational or awareness program regarding analgesic use (33%). Majority of participants believed that there is no sufficient awareness about analgesic. The source of information about analgesic for participants is physician (24%). Panadol analgesic is the most commonly used analgesic (48%) reported by participants. Results showed that there is a significant statistical difference between male and female regard analgesic use (P=0.048) and between different level of educations and analgesic use (P=0.334). Also, there is a highly significant statistical difference between male and female regard reading the leaflet before taking analgesic (P=0.0001) and between the educational level of participants regarding reading the leaflet before analgesic use (P=0.0008). Conclusion: The over-the-counter (OTC) analgesic drugs are commonly used and many patients are unaware of their side effects. The findings of this study showed that people's knowledge, attitudes and practices regarding analgesic use is poor. Also, it is important to improve people's knowledge, attitudes and practices regarding analgesic use to reduce the misconceptions and misguided expectations contributing to inappropriate analgesic use. Therefore, health professional practice should play a major role in people's awareness of the appropriate use of OTC analgesic drugs.

Phosgene still plays an important role as a toxic substance in the chemical industry. Thiess (1968) recently reported observations on numerous cases of phosgene poisoning. A serious difficulty in the clinical handling of phosgene poisoning cases is a relatively long latent period, up to 12 hours, with no obvious signs of severity. At about 12 hours heavy lung edema appears suddenly, however changes can be seen in routine X-rays taken after only a few hours' exposure (Diller et al., 1969). This study was undertaken to correlate these early changes seen by the roengenologist with morphological alterations in the lungs seen in the'light and electron microscopes.Forty-two adult male and female Beagle dogs were selected for these exposure experiments. Treated animals were exposed to 94.5-107-5 ppm phosgene for 10 min. in a 15 m3 chamber. Roentgenograms were made of the thorax of each animal before and after exposure, up to 24 hrs.

The prevention of Diabetic Mellitus (DM) and its complications is the main aim of this study, in addition to the training of lotion foot care application and the development of small scale industry. The research team delivered knowledge in the form of training on Diabetic Mellitus, healthy food, treatment and prevention of complications, and small-scale production of cosmetic products. The aim of this study was to determine the correlation between training on diabetic and lotion foot care application as preventive measures against diabetic complications on the patient's blood glucose levels in the community of residents in Banyuurip Jaya, Surabaya. It was expected from this training that the knowledge of the residents increases and people living with diabetic undergo lifestyle changes and therefore blood sugar levels can be controlled. The parameters measured in this research were blood glucose levels, the anti diabetic drug types consumed, and compliance on diabetics. This study used the data taken from 60 patients with DM over a period of one month. Questionnaires and log books was used to retrieve data and changes in blood glucose levels in diabetic patients. The results showed the demographic data of patients with type 2 diabetic of 85% female and 15% male, with the range of patients aged of 61-70 years of 46.67% and had history of diabetic (90%). The history of drugs consumed by respondents was anti diabetic drugs such as metformin (40%), glimepiride (33.37%) and insulin (6.67%). In addition, the increased knowledge of DM patients after being given the training compared to before training was shown in several questions in the questionnaire. A statistical analysis using t-test analyzed a correlation between training provided in order to enhance understanding of the patient, as well as correlation with blood glucose levels. A paired T-test showed that there was a relationship between the knowledge of trainees before and after training (p less than 0.05). An interesting result was that there was no relationship between blood glucose levels before and after training provided (p> 0.05).

Abstract The use of memory arrays to drive yield enhancement has driven the development of many technologies. The uniformity of the arrays allows for easy testing and defect location. Unfortunately, the complexities of the logic circuitry are not represented well in the memory arrays. As technologies push to smaller geometries and the layout and timing of the logic circuitry become more problematic the ability to address yield issue is becoming critical. This paper presents the added yield enhancement capabilities of using e600 core Scan Chain and Scan Pattern testing for logic debug, ways to interpret the fail data, and test methodologies to balance test time and acquiring data. Selecting a specific test methodology and using today's advanced tools like Freescale's DFT/FA has been proven to find more yield issues, earlier, enabling quicker issue resolution.

This experiment examined changes in body sway after Wingate test (WAnT) in 19 adolescents practicing alpine skiing, subjected to the same type of training load for 4–5 years (10 girls and nine boys). The postural examinations were performed with eyes open (EO), eyes closed (EC), and sway reverenced vision (SRV) in the medial-lateral (ML) and anterior-posterior (AP) planes. The displacement of center of foot pressure (CoP), range of sway (RS), mean sway velocity (MV), way length, and surface area were measured in bipedal upright stance before and after the WAnT to assess the influence of fatigue on postural balance. There were no significant differences in WAnT parameters between girls and boys. Relative peak power (RPP), relative total work (RWtot) were (girls vs. boys) 8.89 ± 0.70 vs. 9.57 ± 1.22 W/kg, p < 0.05 and 227.91 ± 14.98 vs. 243.22 ± 30.24 W/kg, p < 0.05 respectively. The fatigue index (FI) was also on similar level in both genders; however, blood lactate concentration (BLa) was significantly higher in boys (10.35 ± 1.16 mM) than in girls (8.67 ± 1.35 mM) p = 0.007. In the EO examination, statistically significant differences between resting and fatigue conditions in the whole group and after the division into girls and boys were found. In fatigue conditions, significant gender differences were noted for measurements in the ML plane (sway path and RS) and RS in the AP plane. Comparison of the three conditions shows differences between EO vs. EC and SRV in AP plane measured parameters, and for RS in ML plane in rest condition in girls. The strong correlations between FI and CoP parameters mainly in ML plane in the whole group for all examination conditions were noted. By genders, mainly RS in ML plane strongly correlates with FI (r > 0.7). No correlation was found between BLa and CoP parameters (p > 0.06). The presented results indicate that subjecting adolescents of both genders to the same training may reduce gender differences in the postural balance ability at rest but not in fatigue conditions and that girls are significantly superior in postural balance in the ML plane than boys. It was also shown that too little or too much information may be destructive to postural balance in young adolescents.

Mushrooms produce a variety of bioactive compounds that are known to have anti-pathogenic properties with safer and effective therapeutic effects in human disease prognosis. The antibacterial activity of ethanol and methanol extracts of Pleurotus opuntiae were checked against pathogenic microorganisms viz. Pseudomonas aeruginosa ATCC 27853, Proteus mirabilis NCIM 2300, Proteus vulgaris NCIM 5266, Serratia marcescens NCIM 2078, Shigella flexeneri NCIM 5265, Moraxella sp. NCIM 2795, Staphylococcus aureus ATCC 25923 by agar well diffusion method at different concentrations of the extracts. Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of the extracts was determined by INT (Iodonitrotetrazolium chloride) colorimetric assay. Extracts were standardized by thin layer chromatography (TLC) in different solvent systems. The Retention factors (Rf) of different compounds were calculated by high performance TLC (HPTLC) fingerprinting at UV 254, 366, and 540 nm before and after derivatization. The ethanol and methanol extracts of P. opuntiae showed bactericidal activity against all the test pathogens at MIC values of 15.6 to 52.08 mg/mL and 20.81 to 52.08 mg/mL respectively. Whereas the MBC values for ethanol and methanol extract of P. opuntiae against all pathogens were recorded as 26.03 to 62.5 mg/mL and 125 mg/mL respectively. Preliminary mycochemical screening of both the extracts revealed high contents of bioactive compounds. Amongst all the solvent systems used in TLC, the best result was given by chloroform + hexane (8:2) which eluted out 5 different compounds (spots). HPTLC results revealed spots with different Rf values for all the 24 compounds present. Thus, it can be inferred from the present investigation that the mycoconstituents could be an alternative medication regimen and could play a role in new drug discoveries against different infections. Further, the antimicrobial components of these mushrooms can be transformed to bioengineered antimicrobial coatings for surfaces, drug and other hybrid systems for public health implications in combating persistent infections.

Spinal muscular atrophy (SMA) is a genetically heterogeneous group of rare neuromuscular diseases and was until recently the most common genetic cause of death in children. The effects of 2-month nusinersen therapy on urine, serum, and liquor 1H-NMR metabolomes in SMA males and females were not explored yet, especially not in comparison to the urine 1H-NMR metabolomes of matching male and female cohorts. In this prospective, single-centered study, urine, serum, and liquor samples were collected from 25 male and female pediatric patients with SMA before and after 2 months of nusinersen therapy and urine samples from a matching healthy cohort (n = 125). Nusinersen intrathecal application was the first therapy for the treatment of SMA by the Food and Drug Administration (FDA) and the European Medicines Agency (EMA). Metabolomes were analyzed using targeted metabolomics utilizing 600 MHz 1H-NMR, parametric and nonparametric multivariate statistical analyses, machine learning, and modeling. Medical assessment before and after nusinersen therapy showed significant improvements of movement, posture, and strength according to various medical tests. No significant differences were found in metabolomes before and after nusinersen therapy in urine, serum, and liquor samples using an ensemble of statistical and machine learning approaches. In comparison to a healthy cohort, 1H-NMR metabolomes of SMA patients contained a reduced number and concentration of urine metabolites and differed significantly between males and females as well. Significantly larger data scatter was observed for SMA patients in comparison to matched healthy controls. Machine learning confirmed urinary creatinine as the most significant, distinguishing SMA patients from the healthy cohort. The positive effects of nusinersen therapy clearly preceded or took place devoid of significant rearrangements in the 1H-NMR metabolomic makeup of serum, urine, and liquor. Urine creatinine was successful at distinguishing SMA patients from the matched healthy cohort, which is a simple systemic novelty linking creatinine and SMA to the physiology of inactivity and diabetes, and it facilitates the monitoring of SMA disease in pediatric patients through non-invasive urine collection.

Background: Dexmedetomidine is a highly selective α2-adrenoreceptor agonist that produces dose-dependent sedation, anxiolysis, and analgesia without respiratory depression. Due to these ideal sedative properties, there has been increased interest in utilizing dexmedetomidine as a first-line sedative for critically ill patients requiring light sedation. Objective: To evaluate the ability to achieve goal intensive care unit (ICU) sedation before and after an institutional change of dosing from actual (ABW) to adjusted (AdjBW) body weight in obese patients on dexmedetomidine. Methods: This study included patients ≥ 18 years old, admitted to a surgical or medical ICU, required dexmedetomidine for at least 8 hours as a single continuous infusion sedative, and weighed ≥ 120% of ideal body weight. Percentage of RASS measurements within goal range (−1 to +1) during the first 48 hours after initiation of dexmedetomidine as the sole sedative agent or until discontinuation dosed on ABW compared to AdjBW was evaluated. Results: 100 patients were included in the ABW cohort and 100 in the AdjBW cohort. The median dosing weight was significantly higher in the ABW group (95.9 [78.9-119.5] vs 82.2 [72.1-89.8] kg; p = 0.001). There was no statistical difference in percent of RASS measurements in goal range (61.5% vs 69.6%, p = 0.267) in patients that received dexmedetomidine dosed based on ABW versus AdjBW. Conclusion: Dosing dexmedetomidine using AdjBW in obese critically ill patients for ongoing ICU sedation resulted in no statistical difference in the percent of RASS measurements within goal when compared to ABW dosing. Further studies are warranted.
