The objective of this study was to analyze the effects of an 8-week home exercise program with and without Electromyographic biofeedback on the relative activations of vastus medialis obliquus/vastus lateralis using Elec- tromyographic measurement in patients with patellofemoral pain syndrome.2. subjects were randomly allocated into an xercise only?(group 1) and lectromyographic biofeedback+exercise?(group 2..Both groups performed the same exercise program whereas group 2.had incorporated an Electromyographic biofeedback system that provided real time information on the relative acti- vations of vastus medialis obliquus/vastus lateralis during the exercises. The intensity of the knee pain was also recorded on a pain severity scale, *** parameters were measured before and after 8-week of home exercise *** results showed that group 1 had insignificant changes in vastus medialis obliquus/vastus lateralis Electromyographic ratio (p=0.3.5), whereas group 2.had significantly higher vastus medialis obliquus/vastus lateralis Electromyographic ratio (p=0.017) when performing normal activities throughout a 6-hour assessment period,The present result revealed that the incorporation of an Electromyographic biofeedback into a home exercise pro- gram could facilitate the activation of Vastus Medialis Obliquus muscle such that the muscle could be preferentially recruited during daily activities.

A subgroup A of a p-group g is said to be soft in g if Cg(A) = A and |ng(A)/A| = p. In this paper we determined finite p-groups all of whose maximal abelian subgroups are soft; see Theorem A and Proposition 2.4.

The title compound, 4-amino-3.（p-chlorophenyl）-5-（p-methoxybenzyl）-4H-1,2.4- triazole I , C16H15ClN4O）, has been determined using X-ray diffraction techniques and the molecular structure has also been optimized at the B3.YP/6-3. g（d, p） level using density functional theory （DFT）. The triazole ring exhibits dihedral angles of 41.61（15）o and 80.73.11）o with the phenyl rings. The molecules are linked principally by N–H…N hydrogen bonds involving the amino NH2.group and a triazole N atom, forming C（5） chains which are further linked to give a two-dimensional network of molecules. The N–H…N hydrogen bonding is supported by C–H…N hydrogen bond and C–H…π interaction. Intermolecular N–H…N and C–H…N hydrogen bonds produce R2.（9）, R44（10） and R44（2.） rings.

Background: Dietary supplement use(protein/amino acids, weight-loss supplements, performance enhancers) is common among U.S. military members. Reported dietary supplement use in deployed troops is limited and is of concern in settings where troops are exposed to high ambient temperatures, increased physical demands, and dehydration. Our objective was to describe dietary supplement use and adverse events(AEs) among deployed U.S. service members compared with their pre-deployment ***: We conducted an institutional review board(IRB) approved, descriptive study in Afghanistan using a written questionnaire and collected demographic information, dietary supplement use before and during deployment, AEs associated with supplement use, and physical workout routines. Participants were U.S. military personnel of all branches of service deployed to Afghanistan. They were recruited in high-traffic areas in the combat theater. We analyzed the data with descriptive statistics. Paired t-test/Wilcoxon signed-rank test was conducted to examine the before/during deployment changes for continuous data, and Mc Nemar's chi-square test was conducted for categorical data. We constructed separate logistic regression models to determine the best predictors of increases or decreases in dietary supplement use, with demographic information, reasons for using supplements, and education requested/received as covariates in each model. All statistical tests were two-sided at a significance level of 5%(Png deployment. Thirty-five percent of the participants reported no supplement use before or during deployment. The remaining 65% of participants reported increased use and increased frequency of use of supplements(e.g., daily) during deployment compared with predeployment. Additionally, more pe

graphene oxide is a very high capacity adsorbent due to its functional groups and π-π interactions with other compounds. Adsorption capacity of graphene oxide, however, can be further enhanced by having synergistic effects through the use of mixed-matrix composite. In this study, silica-decorated graphene oxide(SgO) was used as a high-efficiency adsorbent to remove Congo red(CR) and Cadmium(Ⅱ) from aqueous solutions. The effects of solution initial concentration(2. to 12. mg/l), solution pH(pH 2.to 7), adsorption duration(0 to 140 min) and temperature(2.8 to 3.0} K) were measured in order to optimize the adsorption conditions using the SgO adsorbent. Morphological analysis indicated that the silica nanoparticles could be dispersed uniformly on the graphene oxide surfaces. The maximum capacities of adsorbent for effective removal of Cd(Ⅱ) and CR were 43.45 and 3.3.3. mg/g based on Freundlich and Langmuir isotherms, respectively. Langmuir and Freundlich isotherms displayed the highest values of Q max for CR and Cd(Ⅱ) adsorption in this study, which indicated monolayer adsorption of CR and multilayer adsorption of Cd(II) onto the SgO, respectively. Thermodynamic study showed that the enthalpy( H) and gibbs free energy( g) values of the adsorption process for both pollutants were negative, suggesting that the process was spontaneous and exothermic in nature. This study showed active sites of SgO( π-π, hydroxyl, carboxyl, ketone, silane-based functional groups) contributed to an enormous enhancement in simultaneous removal of CR and Cd(Ⅱ) from an aqueous solu-tion, Therefore, SgO can be considered as a promising adsorbent for future water pollution control and removal of hazardous materials from aqueous solutions.
