We examined the swimming abilities of tadpoles exposed to the organophosphate chlorpyrifos for 24 h (at concentrations of 0, 1, 5 and 10 µg L-1). Scinax x - signatus, Physalaemus cf cuvieri, and Leptodactylus latrans tadpoles were used as biological models. Our findings evidenced decreased swimming speeds in all tadpole species exposed to chlorpyrifos as compared to the control group, although with significant statistical differences only with P. cuvieri and L. latrans. Changes in swimming ability may indirectly lead to death or alter important growth and development parameters, as the reduced ability to swim can result in increased vulnerability to predators and impacts on feeding, thus altering their fitness.

Изучены рост и развитие бычков — помесей красной степной с казахской белоголовой породой в равнинной провинции Дагестана. Установлено, что помесный молодняк, по сравнению с чистопородным скотом красной степной породы, имеет более высокую живую массу при рождении на 1,8 кг, или 7,3%. При отъеме в 8-месячном возрасте помеси имели живую массу 210 кг против 187,6 кг у красного степного молодняка, что на 22,4 кг, или 11,9% выше. В 12-, 15- и 18-месячном возрасте живая масса помесных бычков равнялась 291,8 кг, 359,7 и 436,6 кг, соответственно, или на 28 кг, 36 и 45,8 кг больше по сравнению с красным степным скотом. Среднесуточные приросты помесных бычков за период выращивания и откорма составили 760 г, что выше на 12,1% по сравнению с чистопородным красным степным молодняком. После заключительного откорма и убоя помесные бычки дали тяжеловесные туши с хорошим поливом. По массе парной туши они превосходили чистопородных аналогов на 31,3 кг, или 15,6% с преимуществом выхода туши на 2,4%. Убойный выход у бычков опытной группы составил 58,7%, контрольной — 55,8%. От помесных бычков были получены тяжеловесные шкуры массой 27,1 кг, от чистопородных — 21,6 кг, преимущество по этому показателю имели помесные животные 5,5 кг, или 25,4%. Для увеличения производства говядины в равнинной провинции Дагестана рекомендуем скрещивание коров красной степной породы с быками казахской белоголовой породы. The growth and development of bulls of red steppe crossbreeds with the Kazakh white-headed breed in the flat province of Dagestan were studied. It was found that young crossbreed animals in comparison with purebred red steppe cattle have a higher live weight at birth by 1,8 kg or 7,3%. When weaning at 8 months of age, cross-bred bulls had a live weight of 210 kg against 187,6 kg in red steppe young, which is 22,4 kg, or 11,9% higher. At 12, 15 and 18 months of age, the live weight of crossbred bulls was 291,8 kg, 359,7 and 436,6 kg, respectively, or 28 kg, 36 and 45,8 kg more than the red steppe cattle. The average daily growth of cross-bred bulls during the growing and fattening period was 760 g compared to 678 g, that is, they were 12,1% higher compared to purebred red steppe young. After the final fattening and slaughter, the cross-bred bulls gave heavy carcasses with good watering. By weight of the paired carcass, they were superior to purebred counterparts by 31,3 kg or 15,6% with an advantage of 2,4% carcass yield. The slaughter yield of bulls in the experimental group was 58,7%, 55,8% in the control group, respectively, with an advantage in favor of crossbreeds of 2,9%. Heavy skins weighing 27,1 kg were obtained from crossbreed bulls, 21,6 kg from purebred ones, and crossbreed animals of 5,5 kg or 25,4% had an advantage in this indicator. Studies have shown that in order to increase beef production in the lowland province of Dagestan, it is necessary to use crossbreeding of the breeding stock of the red steppe breed with bulls of the Kazakh white-headed breed.

Newborn with low birth weight (LBW) in Indonesia is relatively high even up to 16,9 %. The role of the neonatal nurse is highly expected to provide care for newborn babies with LBW by giving supportive environment. Neonatal Developmental Care (NDC) is one of intervention that aims to implement modifications to the nursery environment and care practices to promote growth and development of newborn with LBW. Most of nurses still have no information related NDC and its implementation in neonatal room. This study aimed to explore the influence of NDC information exposure toward nurse’s attitude. A quasi-experimental with before-and-after design was applied. This study recruited 21 nurses to participate as intervention and control group. The Paired T-Test was performed to analyze the data. The results showed there is an influence of NDC information exposure toward nurse’s attitude in caring for newborn with low birth weight by P-value 0,00. This study recommend that NDC can be one of nursing intervention for caring newborn baby with LBW in order to optimize caring for infant along caring for growth and development during their treatment in hospital.

Objective: This study aimed to investigate the application of MEIR (Massage, Exercises, Intelligence training, and Rehabilitation training) in Chinese VLBW infants and to observe its effects on infants’ growth and development. Methods: Clinical data of 92 VLBW infants who were treated at the neonatal intensive care unit (NICU) of Loudi Central Hospital were retrospectively analyzed. The patients were grouped as the MEIR group (n=47) and controls (n=45). Physical and neurodevelopment development were compared between the two groups. Results: There were differences in height and weight and head circumference between the two groups at all corrected ages (all P<0.05). Abnormal motions, reflexes, muscular tension, audio-visual reactions, and posture, and the total numbers of abnormalities of 3-, 6-, 9- and 12-corrected month-old infants in the MEIR group were lower than in the control group (all P<0.05). The mental development index and psychomotor development index of 6- and 12- corrected month infants in the MEIR group were higher than in the control group (all P<0.05). Conclusion: MEIR could improve the physical and neurological developments of VLBW infants, reduce the incidence of adverse events, and improve their growth and development.

In this study, mints were regenerated from calluses irradiated by γ - rays (Co-60) at doses from 0 to 70 Gy. After 4 times of propagation, the M1V4 mints were transferred in a greenhouse for assessments of growth, development and essential oil content. Mint regenerated from calluses irradiated at low doses (0, 3, 4, 6, 8 and 10 Gy) showed no morphological difference compared to the control plants. However, low-dose irradiated mints showed better effect on growth and development, and mints regenerated from 6Gy-irradiated sample had essential oil content with 1.3 times higher than that of control group. In case of plants irradiated at higher dose (30, 40, 50, 60 and 70 Gy), there were morphological variations such as stem become bigger and color of stem become purple. Especially, samples irradiated at 60 Gy showed better in growth, development and essential oil content (1.34 times higher than the control plants) and these characters were stable in M1V4. Among the irradiated mints, purple stem variations had the highest essential oil yield with 1.7 times higher than that of the original plants.

<p style="text-align: justify;">Many physiological processes related to plant growth and development are under the influence of growth regulators, which also have an impact on pollen germination. In this study, the effects of two brassinosteroid compounds, epibrassinolide and 22S,23S-homobrassinolide, and gibberellic acid (GA<sub>3</sub>) on <em>in vitro</em> pollen germination of two table grape cultivars, ‘Italia’ and ‘Cardinal’ (<em>Vitis vinifera</em> L.), were determined. A total of 28 treatments, alone and in combination, were applied to freshly collected pollens which were sown on a basic medium with 1% agar and 20% sucrose. Petri dishes were kept at 26±1°C for 24 hours. Counting of the germinated pollens revealed that the effects of these plant hormones were cultivar- and substance-specific. The cultivar ‘Italia’ was not influenced by the treatments (the highest germination ratio being 44.4% from 0.001 mg L<sup>-1</sup> epibrassinolide) as opposed to the cultivar ‘Cardinal’. The highest germination ratio in ‘Cardinal’ was about 50% in pollens treated with 25 mg L<sup>-1</sup> GA<sub>3</sub> + 0.01 mg L<sup>-1</sup> epibrassinolide. The control group resulted in 32.38% germination. Combining GA<sub>3</sub> with epibrassinolide provided slightly higher germination ratios compared to combining GA<sub>3</sub> with 22S,23S-homobrassinolide. </p>

Background: Adequate nutrition is required for growth and development in children. This study tested the effectiveness of nutrition education on knowledge and BMI-for-age (BFA) of school-aged children in the Kumasi Metropolis. Methods: Children, aged 9-13 years old were recruited from ten randomly selected primary schools in the Metropolis. The schools were randomly allocated into 3 groups: nutrition education (3 schools), physical activity (PA) education (3 schools), both interventions (2 schools), or control (2 schools). Following a baseline nutrition and PA knowledge and status assess- ment in 433 children, twice-monthly nutrition and PA education and demonstrations were carried out for 6 months, followed by a post-intervention assessment. Results: PA and nutrition knowledge improved in all groups (P<0.001); the highest improvement was among those who received both interventions (31.0%), followed by the nutrition education group (29.8%), and the least, the control group (19.1%). Overall, BFA improved by +0.36, from baseline (-0.26) to end of the intervention (+0.10, P<0.001). Within the groups, the nutrition group (+0.65, P<.001) had the highest improvement, then, both the intervention group (+0.27, P<0.001), the PA group (+0.23, P<0.001) and lastly, the control group (+0.18, P=0.001). Conclusion: Nutrition education could improve knowledge and BMI-for-age in school-aged children in Ghana.

The purpose of this project was to undertake a long-term follow-up of participants in the Trois-Rivières Growth and Development Study. Some 20 years after their initial involvement in the program, two groups were compared: experimental subjects (n =150) who had received 5 one-hour sessions of specialized physical education per week throughout their 6 years of primary school, and the original control group (n = 103). All subjects completed a questionnaire regarding current patterns of physical activity (PA), attitudes and beliefs about PA, and perceived barriers to PA. Principal results indicate: (a) More experimental than control women exercise 3 times or more per week, (b) experimental subjects more commonly perceived their health to be very good to excellent, (c) control subjects in general felt less psychological dependency on exercise, and (d) women in the experimental group had a lower relative risk of back problems.

Our previous studies have suggested that Staphylococcus aureus L-forms are able to pass through the placental barrier of mice from the maternal side to the fetal body and affect fetal growth and development, but little is known about the direct influence of S. aureus L-forms on embryos during the critical period of organogenesis. Mouse embryos at gestational day 8.5 were cultured in vitro for 48 h with 0, 50, 100, 200 or 400 c.f.u. S. aureus L-forms ml−1. At the end of the culture period, the mouse embryos were assessed morphologically for viability, growth and development. Bacteriological and immunohistochemical staining were used to determine the existence of S. aureus L-forms in embryonic tissues. We found that both crown–rump length and head length of mouse embryos exposed to S. aureus L-forms at a concentration of 50 c.f.u. ml−1 were reduced. When the mouse embryos were exposed to 100, 200 or 400 c.f.u. S. aureus L-forms ml−1, the total morphological score, number of somites, dry embryo weight, yolk sac diameter, crown–rump length and head length were significantly lower than those of the control group. With the increased concentration of S. aureus L-forms in the culture medium, there were fewer normally developed embryos and more embryos with abnormalities or retardation in growth. S. aureus L-forms detected by Gram-staining and immunohistochemical detection of antigen were found in the tissues of embryos infected by S. aureus L-forms. These data suggest that S. aureus L-forms exert a direct teratogenic effect on cultured mouse embryos in vitro.
