An homologous series of ω-naphthyl, aliphatic acids from the acetic to the hexoic has been presented to the author by Dr. R. H. Manske, and the physiological activity of these has been determined by the rooting response of plant cuttings treated with solutions of each. Statistically significant positive effects have been noted on the number of cuttings that rooted, the number and length of roots per rooted cutting, and the mean root length. The results with several plant species indicate that activity exists up to and including naphthyl hexoic acid, the highest member of the series tested. A noteworthy feature of the results is the activity of the acids with an even number of carbon atoms in the side chain; those with an odd number have activity of a lower order.

The physiological activity of a series of indolyl acids, from the acetic to the valeric, including 5-methyl-indolylpropionic, has been determined by the rooting responses of Lonicera tartarica cuttings treated with solutions of each. Indolylbutyric acid was the most active chemical, affecting the number and length of roots per rooted cutting, the mean root length, the green weight of leaves, and the fresh root weights. Indolylacetic acid had significant effects on the number and length of roots per rooted cutting. Slight activity was shown by indolylpropionic acid, but neither indolylvaleric acid nor 5-methyl-indolylpropionic showed any significant treatment effects. None of the acids affected the number of cuttings rooted.

Norway spruce cuttings were treated with phytohormone dusts, and nutrient solution was added to the sand in which some of the cuttings were planted. The nutrient treatment greatly increased the number of rooted cuttings and the number that developed new growth, and reduced the number that died. Although talc alone increased top growth, indolylacetic acid, present in three concentrations in talc, had no significant effect on the number of cuttings rooted or dead. However, the hormone dust treatment effected a significant reduction in the length of root per rooted cutting and the mean root length. The results indicate that nutrient salts may, under certain conditions, have a marked influence on the rooting and growth of Norway spruce cuttings.

Plant stem cuttings were treated in a factorial series with talc dusts containing naphthylbutyric acid, nutrient salts, an organic mercurial disinfectant, finely divided silver metal, thiamin, and nicotinic acid. Naphthylbutyric acid treatment increased the number of roots for cuttings of Physocarpus and Iresine and reduced the mean root length of Lonicera. Nutrient salt treatment increased the number of roots on Iresine cuttings and the mean root length of Lonicera. Differential effects were found for treatments with naphthylbutyric acid and each of organic mercury, metallic silver, and nutrient salts. Organic mercury at 50 p.p.m. and metallic silver at 5000 p.p.m. were similar in their effects. Thiamin and nicotinic acid had no significant effect on the rooting responses.Naphthylacetic acid was prepared in talc at concentrations of 4000, 2000, 1000, and 500 p.p.m. and indolylbutyric, naphthylbutyric acids, and potassium naphthylhexoate at molecularly equivalent concentrations. When applied in a talc carrier dust to cuttings of seven species naphthylacetic and indolylbutyric acids were substantially similar in their effects while naphthylbutyric acid and potassium naphthylhexoate showed a lower order of physiological activity. Effects of chemicals judged by the rooting responses of cuttings tended to be similar over the concentration range. On the average, the 4000 p.p.m. dosage was injurious, while the two lowest dosages failed to differ in effects between themselves.

Indolylbutyric acid and oestrone, separately and in combination in a series of talc dusts, were applied to dormant cuttings of Lonicera tartarica. Indolylbutyric acid treatment, averaged over all oestrone treatments, increased the number of cuttings rooted, the number and length of roots per rooted cutting, the mean root length, and the green weight of leaf produced by the dormant cuttings. The average effect of oestrone on these responses was depressive throughout. Oestrone tended to offset the beneficial effects of the plant growth stimulating chemical, excepting the combination of 100 p.p.m. of each which increased root length. Oestrone alone did not reduce either the number or lengths of root per rooted cutting.The results indicated that the number and length of roots and the green weight of leaf produced are more sensitive responses for demonstrating differences due to indolylbutyric acid concentration in talc than is the percentage of cuttings rooted.

TMPAThe effect of substitutions in the ring and in the side chain on the crystal structure of N- (2,4,6-trimethylphenyl)-methyl/chloro-acetamides of the configuration 2,4,6-(CH3)3C6H2NH-COCH3− yXy (X = CH3 or Cl and y = 0,1, 2) has been studied by determining the crystal structures of N-(2,4,6-trimethylphenyl)-acetamide, 2,4,6-(CH3)3C6H2NH-CO-CH3 (); N-(2,4,6- trimethylphenyl)-2-methylacetamide, 2,4,6-(CH3)3C6H2NH-CO-CH2-CH3 (TMPMA); N-(2,4,6- trimethylphenyl)-2,2-dimethylacetamide, 2,4,6-(CH3)3C6H2NH-CO-CH(CH3)2 (TMPDMA) and N-(2,4,6-trimethylphenyl)-2,2-dichloroacetamide, 2,4,6-(CH3)3C6H2NH-CO-CHCl2 (TMPDCA). The crystallographic system, space group, formula units and lattice constants in Å are: TMPA: monoclinic, Pn, Z = 2, a = 8.142(3), b = 8.469(3), c = 8.223(3), β = 113.61(2)◦; TMPMA: monoclinic, P21/n, Z = 8, a = 9.103(1), b = 15.812(2), c = 16.4787(19), α = 89.974(10)◦, β = 96.951(10)◦, γ =89.967(10)◦; TMPDMA: monoclinic, P21/c, Z = 4, a =4.757(1), b= 24.644(4), c =10.785(2), β = 99.647(17)◦; TMPDCA: triclinic, P¯1, Z = 2, a = 4.652(1), b = 11.006(1), c = 12.369(1), α = 82.521(7)◦, β = 83.09(1)◦, γ = 79.84(1)◦. The results are analyzed along with the structural data of N-phenylacetamide, C6H5NH-CO-CH3; N-(2,4,6-trimethylphenyl)-2-chloroacetamide, 2,4,6-(CH3)3C6H2NH-CO-CH2Cl; N-(2,4,6-trichlorophenyl)-acetamide, 2,4,6-Cl3C6H2NH-COCH3; N-(2,4,6-trichlorophenyl)-2-chloroacetamide, 2,4,6-Cl3C6H2NH-CO-CH2Cl; N-(2,4,6-trichlorophenyl)- 2,2-dichloroacetamide, 2,4,6-Cl3C6H2NH-CO-CHCl2 and N-(2,4,6-trichlorophenyl)- 2,2,2-trichloroacetamide, 2,4,6-Cl3C6H2NH-CO-CCl3. TMPA, TMPMA and TMPDCA have one molecule each in their asymmetric units, while TMPDMA has two molecules in its asymmetric unit. Changes in the mean ring distances are smaller on substitution as the effect has to be transmitted through the peptide linkage. The comparison of the other bond parameters reveal that there are significant changes in them on substitution.

Background: Common clinical problems after surgery include nausea, vomiting and ileus that many patients complain of after their surgery. These complications can delay the patient's discharge from hospital. Nowadays, to reduce drug side effects, the use of complementary medicine, including reflexology, has received a great deal of attention. Aim: To compare the effect of hand and foot reflexology massages on the severity of nausea, vomiting and ileus in patients after abdominal surgery. Methods: This is a clinical trial study that was conducted between 2013 and 2015 in the emergency surgical departments of Imam Reza (AS) and Ghaem (AS) hospitals in Mashhad. The samples of this study included 90 women with cholecystitis and appendicitis who met the inclusion criteria. In this study, patients were randomly divided into 3 groups of hand reflexology massage, foot reflexology massage and control. To check the digestive status, gastrointestinal sounds were checked every hour using a clinical stethoscope. Also, information on gas and feces elimination was collected and recorded every hour. The intervention was performed 1 and 12 hours after the surgery. In both groups of hands and foot reflexology massages, after general massage of the hands and feet, the areas related to the abdominal distension and removal of the ileus were pressed. It should be noted that, the duration of massage for each person was 10 minutes (20 minutes in total). Data were analyzed by SPSS software version 16 using Chi-square, Fisher’s exact test, two-way ANOVA, Kruskal-Wallis test and repeated measures ANOVA. Results: There was no statistically significant difference in the mean score of severity of nausea before the intervention between the three groups (p = 0.90), but after the intervention a significant difference was observed in the mean score of severity of nausea between the three groups (p=0.002). Also, the result of ANOVA test with repeated measure showed a statistically significant difference in the mean score of nausea by group and stage (p<0.001). There was also no statistically significant difference in the frequency of vomiting severity between the three groups after the intervention. However, at 4 and 24 hours after the intervention, a statistically significant difference was observed between the three groups in that regard. Conclusion: The results showed that both types of hand and foot reflexology massage has positive effects on nausea and return of gastrointestinal movements, so nurses can use reflexology as a non-pharmacological and complementary method to reduce the severity of nausea and return gastrointestinal movements in postoperative patients. Since the reflexology had little or no effect on the severity of vomiting and the acceleration of gastrointestinal movements in patients, further studies in this area are recommended.

Abstract Background: In order to prevent oral diseases, the use of appropriate educational methods at childhood is one of the most important determinants of the public health. Therefore, the aim of this study was to investigate the effect of training through animations and games on oral health self-efficacy and self-care behaviors in students aged 6-12 years old. Methods: In this interventional study, 82 students were selected using cluster random sampling (38 subjects in the case group and 44 in the control group). The case group received 4 sessions of blended learning per week including animations and games while the control group received routine school education. Data were collected in six domains, including demographics, self-care, knowledge, attitude, behavior and self-efficacy before and 5 months after the intervention using a questionnaire. SPSS version 20 was used for data analysis. Results: Five months after the intervention, the mean score of self-care increased from 3.8 to 4.8 of 5, the mean score of self-efficacy increased from 36.8 to 48.9 of 70, and the mean score of behavior increased from 17.07 to 18.29 of 32, indicating significant changes (p < 0.05). There were no significant changes in these variables in the control group (p >0.05) Conclusion: Use of combined methods for oral health self-care education has positive effects on the students' performance and self-efficacy.

Promoting the coordinated development of industrialization and the environment is a goal pursued by all of the countries of the world. Strengthening environmental regulation (ER) and improving green total factor productivity (GTFP) are important means to achieving this goal. However, the relationship between ER and GTFP has been debated in the academic circles, which reflects the complexity of this issue. This paper empirically tested the relationship between ER and GTFP in China by using panel data and a systematic Gaussian Mixed Model (GMM) of 177 cities at the prefecture level. The research shows that the relationship between ER and GTFP is complex, which is reflected in the differences and nonlinearity between cities with different monitoring levels and different economic development levels. (1) The relationship between ER and GTFP is linear and non-linear in different urban groups. A positive linear relationship was found in the urban group with high economic development level, while a U-shaped nonlinear relationship was found in other urban groups. (2) There are differences in the inflection point value and the variable mean of ER in different urban groups, which have different promoting effects on GTFP. In key monitoring cities and low economic development level cities, the mean value of ER had not passed the inflection point, and ER was negatively correlated with GTFP. The mean values of ER variables in the whole sample, the non-key monitoring and the middle economic development level cities had all passed the inflection point, which gradually promoted the improvement of GTFP. (3) Among the control variables of the different city groups, science and technology input and the financial development level mainly had positive effects on GTFP, while foreign direct investment (FDI) and fixed asset investment variables mainly had negative effects.

Norway spruce cuttings collected in November from the upper part of the tree were treated with a series of talc dusts containing indolylacetic and naphthylacetic acids, each at 0, 1000, and 5000 p.p.m., combined with cane sugar at 0 and 10%, and ethyl mercuric phosphate at 0 and 50 p.p.m., and propagated in a greenhouse. Indolylacetic acid at 1000 p.p.m. increased rooting by about 10% to 42.5%, three months after planting, but at 5000 p.p.m. reduced it significantly. Naphthylacetic acid reduced rooting at both concentrations. Indolylacetic acid increased the length of root per rooted cutting. Sugar in combination with indolylacetic acid inhibited the increase in root length caused by the hormone alone; organic mercury alone or in combination with indolylacetic acid reduced root length, but sugar and mercury in combination exerted no greater inhibition than either alone.Mean root length was affected only by indolylacetic acid, which increased it.
