Предложен механизм блокировки и последующей аннигиляции эндогенных микротрещин за счёт их внутриструктурной самокоррекции. Установлено, что при трибомеханических процессах фрикционного взаимодействия в условиях аддитивного влияния температурных флуктуаций и удельных нагрузок в контактной зоне имеет место одновременное действие всех возможных с точки зрения физико-химии аномальных превращений в твёрдой фазе. Результатом которых является термическое разложение карбидов и образование структурно свободного α-графита. Результаты, полученные при испытаниях, позволяют предположить, что антифрикционный поверхностный слой, содержащий графит, образуется в режиме приработки и его состав, как и равновесная шероховатость, воспроизводятся и поддерживаются, образуя целостную систему динамически устойчивых износостойких структур, во всём диапазоне нормального износа.

El analfabetismo es un problema que impide el desarrollo social y económico de las personas, afectando la calidad de vida y la salud. En este artículo se resume una experiencia de aplicación del método cubano “Yo sí Puedo”, para ayudar a reducir el analfabetismo en la Parroquia de Cusubamba, ubicada en Cotopaxi, Ecuador. Este método consiste en la asociación de las letras del alfabeto a un número, que forman palabras y grafemas, facilitando la memorización, combinando el uso de medios audiovisuales con el análisis y síntesis de los contenidos. El objetivo general fue aumentar el número de adultos alfabetizados, sin exclusiones de ningún tipo. Para ello se promovió la lectura con mediana fluidez y la redacción de oraciones, párrafos cortos y cartas. Esta experiencia vinculó los aprendizajes de lectura y escritura con eventos o situaciones significativas para los participantes, con lo cual se facilitó su motivación, comprensión y estudio. Entre los resultados obtenidos, se logró alfabetizar a 380 personas, muchos de las cuales lograron realizar trámites cotidianos que posibilitarán en el futuro otros logros personales a los cuales estaban limitados por el analfabetismo. Asimismo, mejoraron sus expectativas laborales y relaciones mediante el uso de celulares. Con ello se fortalece una de las metas de la Organización de las Naciones Unidas para la Educación, la Ciencia y la Cultura, al concebir la alfabetización como un incremento continuo de niveles de competencias, comenzando por conocimientos funcionales de lectura y escritura, equivalente al nivel que se obtiene con la enseñanza básica.

Published: December 2017

Objective: The study aims to evaluate the surgical closure of Atrial Septal Defect (ASD) and concomitant surgical procedures needed at Cardiac Care Centre. Introduction: An ASD is a hole of variable size in the atrial septum. A patent foramen ovale that is functionally closed by overlapping of limbic tissue superiorly and the valve of the fossa oval inferiorly (in response to the normal left-to-right atrial pressure gradient) is excluded. ASDs generally permit left-to-right shunting at the atrial level. Partial anomalous pulmonary venous connection (PAPVC) is a condition in which some but not all pulmonary veins connect to the right atrium or its tributaries, rather than to the left atrium. Methodology: A prospective cohort study was done at Tabba heart institute. 115 consecutive patients were reviewed and investigated. All the patients with surgical closure of ASD and concomitant surgical procedures who returned for follow-up from June 2011 to May 2016 in the study were included as population sample. Results: Total ASD repair only patients were 80 and patients who needed concomitant procedures too were 35. The size of the defect ranged from 3mm to 58mm, with a mean of 26.96±11.02mm. The relative frequencies of different ASDs were secundum 57 (80.2%), primum 4 (5.6%), and sinus venosus 10 (14.08%). Major post-operative complications by Age group and by procedure were evaluated and presented. Conclusion: It was concluded from our results that surgical repair of atrial septal defects and its variants is associated with very low morbidity in different age groups due to its excellent results.

Pengaruh Suplai Nitrogen pada Media Kultur dan Intensitas Cahaya Terhadap Proses Fotosintesis Chlamydomonas reinhardtiiOrganisms use nitrogen to produce, among others, amino acids, proteins, and nucleic acids. In this study, the effects of various concentrations of ammonium in culture media on the photosynthetic performance of Chlamydomonas reinhardtii were done under two light conditions: low and high intensity. The microbes were grown at low (75% NH4Cl dosage), normal (100% NH4Cl dosage, which was 2 M NH4Cl), and high (125% NH4Cl dosage) nitrogen content. Cells density and chlorophyll content were quantitatively determined. Immunoblotting technique was used to separate proteins based on molecular mass. In both low and high light intensity, cells grown in 75% NH4Cl dosage culture medium showed lower cell density and chlorophyll concentration than those grown in 100% and 125% NH4Cl dosage media. The later two media produced almost the same amount of cell density and chlorophyll concentration. In conclusion, 75% NH4Cl dosage was insufficient for C. reinhardtii cells to grow well. The results also showed that accumulation of photosystem I (PsaA and PsaD/F) and light harvesting complex II (LHCII) were higher in low light than in high light intensity.AbstrakOrganisme menggunakan nitrogen diantaranya untuk memproduksi asam amino, protein, dan asam nukleat. Dalam percobaan ini pengaruh berbagai konsentrasi amonium dalam media pada fotosintesis Chlamydomonas reinhardtii dilakukan di bawah dua kondisi cahaya: intensitas rendah dan tinggi. C. reinhardtii ditumbuhkan dalam medium dengan dosis nitrogen (N) rendah (75% dosis NH4Cl), normal (100% dosis NH4Cl, yakni NH4Cl 2 M), dan tinggi (125% dosis NH4Cl). Parameter yang diukur adalah kepadatan sel dan konsentrasi klorofil. Analisis protein dilakukan dengan imunobloting untuk memisahkan protein berdasarkan massa molekul. Pada intensitas cahaya rendah dan tinggi, sel-sel pada medium dengan 75% NH4Cl menunjukkan kepadatan sel dan konsentrasi klorofil lebih rendah dibandingkan dengan 100% NH4Cl dan 125% NH4Cl, di mana kedua media ini menghasilkan kepadatan sel maupun konsentrasi klorofil yang hampir sama. Dengan demikian dapat disimpulkan bahwa 75% NH4Cl tidak cukup bagi C. reinhardtii untuk tumbuh dengan baik. Selain itu, akumulasi fotosistem I (PsaA dan PsaD/F) dan kompleks pemanenan cahaya II (LHCII) lebih tinggi pada sistem fotosintesis dengan intensitas cahaya rendah dibandingkan cahaya tinggi.Kata kunci: Chlamydomonas reinhardtii, fotosintesis, intensitas cahaya, klorofil, nitrogen

Effectiveness of Mercury Chloride (HgCl2) in Sterilization of Teak (Tectona grandis L.f.) In VitroThe main obstacle in obtaining sterile materials in in vitro cultures derived from meristems is high level of surface contamination caused by fungi and bacteria, which often results in explant death. The objective of this study was to obtain an appropriate mercury chloride (HgCl2) concentration for the sterilization of Tectona grandis nodes in in vitro culture. One cm long-sized nodes with 0.2 mm diameter were immersed in HgCl2at concentrations of 0, 100, 200 and 300 mg/L for 3 minutes. The results showed that the higher concentration of HgCl2was able to suppress the growth of fungi and bacteria and increased the percentage of aseptic explants. The best HgCl2concentration was 300 mg/L since it suppressed the growth of fungi and bacteria up to 100% and 75%, respectively, and produced the highest aseptic explants of 85% at 9 days after treatment. The small sized explants supported the sterilization process and reduced browning levels.Keywords: Browning, HgCl2, in vitro, sterilization, T. grandisABSTRAKKendala utama dalam mendapatkan material steril pada kultur in vitro yang berasal dari meristem adalah tingginya tingkat kontaminasi permukaan yang disebabkan oleh jamur dan bakteri, dan sering menyebabkan kematian eksplan. Tujuan penelitian ini adalah untuk memperoleh konsentrasi merkuri klorida (HgCl2) yang tepat untuk sterilisasi eksplan tunas samping tanaman jati (Tectona grandis) pada kultur in vitro. Tunas samping berukuran 1 cm dan diameter 0,2 mm direndam dalam HgCl2 pada konsentrasi 0, 100, 200 dan 300 mg/L selama 3 menit. Hasil penelitian menunjukkan bahwa penambahan konsentrasi HgCl2 yang semakin tinggi mampu menekan pertumbuhan jamur dan bakteri pada eksplan serta meningkatkan persentase eksplan aseptik. HgCl2 dengan konsentrasi 300 mg/L merupakan konsentrasi terbaik karena dapat menekan pertumbuhan jamur hingga 100% dan bakteri mencapai 75%, serta menghasilkan tingkat eksplan aseptik dan hidup tertinggi yaitu sebesar 85% pada 9 hari setelah perlakuan. Ukuran eksplan yang kecil mendukung proses sterilisasi dan mengurangi tingkat browning.

Published: December 2017

Hygromycin B was extracted with ethyl acetate, which separates organic phase from aqueous phase in the broth culture filtrate, only the aqueous phase showed significant antimicrobial activity by using agar well diffusion technique. At a concentration of 25mg/ml (as crude extract), this phase excreted its activity against the test microorganisms which include; one G(+) bacteria (Staphylococcus aureus), five G(–) bacteria (Pseudomonas aeruginosa , Proteus mirabilis, Escherichia coli , Klebsiella pneumoniae, Salmonella typhi) and one yeast (Saccharomyces cerevisiae).
After detecting the aminoglycoside hygromycin B by the Thin Layer Chromatography (TLC) method to ensure presence of the antibiotic, same flow rate (Rf) value (0.357) as that of the standard hygromycin B was obtained.
Results of the optimization conditions showed that the highest antimicrobial activity of hygromycin B was obtained at a medium pH of 8 and incubation temperature of 35°C for 10 days. When the toxicity of hygromycin B crude extract under such conditions was examined on mice liver, a mild effects were appeared

Published: December 2017

OBJECTIVE: To determine the effects of kicking leg preference on the bilateral leg strength asymmetries of amateur football players. METHODS : Thirty-four right-dominant (RD) and twenty-three left-dominant (LD) amateur football players volunteered to participate in the study. Squat and countermovement jump, standing long jump, and isokinetic knee strength (at 60, 180 and 300[Formula: see text]/s) were tested with respect to inter-limb asymmetry index (ASI). RESULTS: There were significant differences in horizontal jump and H/Q ratio at 60[Formula: see text]/s between DL and NDL in all football players. There were also significant differences in standing long jump, hamstring peak torque at 180[Formula: see text]/s and H/Q ratio at 60[Formula: see text]/s in the LD football players ([Formula: see text] 0.05). Moreover, the LD group had greater percentage of subjects with ASI [Formula: see text] 15% for standing long jump, hamstring peak torque at 180[Formula: see text]/s. Furthermore the percentage of subjects with H/Q Ratio [Formula: see text] 0.60 for 60[Formula: see text]/s was greater in the LD players’ DL. CONCLUSION: Bilateral leg strength asymmetries may be affected by a single leg predominantly in the mobilization workouts. Having higher inter-limb asymmetry index, LD players may be screened and trained to minimize leg strength asymmetries.

Published: December 2017

OBJECTIVE: Lipid supplementation improves developmental outcomes in preterm infants. Carnitine is essential for lipid metabolism; however, despite high risk for carnitine deficiency, there are no standards for carnitine supplementation in preterm infants receiving total parenteral nutrition (TPN). Our objective was to assess knowledge, beliefs and practices regarding preterm carnitine deficiency and supplementation among neonatal practitioners. METHODS: Cross-sectional electronic survey administered via a nationally representative listserv of neonatal practitioners. RESULTS: 492 respondents participated in the survey. Only 21% of respondents were aware that carnitine is secreted by the placenta. 72% believed that carnitine deficiency was common, and 60% believed deficiency could have serious consequences. Five percent routinely screened for deficiency, and 40% routinely provided carnitine supplementation. Respondents with >5 years’ experience were more likely to report using carnitine supplementation (50% vs. 38%). CONCLUSIONS: Although most respondents believed that carnitine deficiency is common and could have serious consequences, few screened for deficiency and fewer than half routinely supplemented. Thus, many preterm infants remain at risk for carnitine deficiency. Further research is needed to elucidate the risks of carnitine deficiency in these vulnerable infants.

Published: December 2017

BACKGROUND: In preterm infants fortification of human milk with human milk fortifiers (HMF) to optimize nutrition and growth is standard practice. We compared clinical, nutrition and growth outcomes in infants receiving two types of liquid HMF (LHMF). METHODS: Clinical, nutrition and growth outcomes were compared between infants admitted to a level IV NICU, and born with birth weight less than or equal to 1800 grams, between 10/1/2014-12/31/2014 and received human milk with acidified LHMF (ALHMF) and between 1/1/2015-4/31/2015 and received human milk with heat treated LHMF (HTLHMF). RESULTS: Of the 85 qualifying infants, 67 received human milk and LHMF. ALHMF group had significantly higher incidence of metabolic acidosis and lower bicarbonate and base excess levels relative to infants receiving HTLHMF ( P < 0.001). There were no significant differences by LHMF status in other clinical outcomes and nutrition and growth outcomes. In multivariate analyses, ALHMF use was associated with metabolic acidosis, and lower base excess and bicarbonate levels. CONCLUSION: In our study, the clinical, nutrition and growth outcomes between the two LHMF groups were similar. However, use of ALHMF in preterm infants was associated with increased incidence of metabolic acidosis in our cohort. Further randomized control trials are warranted to evaluate these findings.
