Retrospective Reports of Dream Characteristics and Preferences for Organic vs Junk Foods
No full text The authors investigated correlations between retrospective dream characteristics, food preferences, and eating attitudes. Graduate students (7 men, 42 women) at Santa Clara University were administered the MEGA food scale and the KJP Dream Inventory. High intake of organic food was positively correlated with reports of multiple dream factors. Conversely, high scores on preferences for fast food, potato chips, and carbohydrates were negatively correlated with several factors. Findings are discussed in terms of the hypothesis that certain foods may influence dreaming. </jats:p
A Service Model for Home-based Care in Late Stage Dementia: Scope, Scale and Policy Implications
No full textDementia care as it exists today in India is threadbare. Quality of life of dementia sufferers needs much improvement. Considering the resource constraints, care models for chronic conditions like dementia will be sustainable only if they are cost effective. Community-based care, preferably at home with a health worker providing domiciliary support, would be ideal, and evidence in support of such care is accumulating. However, implementing such care in real world settings is a challenge even for the well-resourced health systems of high income countries, and most of the responsibilities will have to be entrusted to a low cost workforce with multidisciplinary skills. The author describes a putative model for home-based dementia care that horizontally integrates two programs which already function in Kerala — District Mental Health Program and Palliative Care Program
Borderline intelligence, disability provisions and fuzzy borders
No full textThe diagnosis and boundaries of borderline intellectual functioning (BIF) lack clarity. The nosological status in DSM 5 and ICD 10 and 11 are also dubious. The provision of 'borderline disability' of 25 % for the category of Intellectual Disability, in the RPWD (Rights of persons with disability) act, falls below the benchmark disability criteria. The Kerala State commissioner for persons with disabilities categorises those with IQ between 70 and 84, as 'borderline intelligent' and provides the benefits of scribe/interpreter to them. Can the psychiatrist certify an entity which does not exist in the current classificatory systems? The author tries to highlight the fallacies in the implementation of disability provisions in Kerala for students with BIF and provides alternative solutions vis a vis the disability plea
Isolation of Acanthamoeba isolates belonging to T2, T3, T4 and T7 genotypes from environmental samples in Ankara, Turkey
No full textAcanthamoeba keratitis is a blinding infection that is becoming increasingly important in human health. Early diagnosis is a prerequisite for successful treatment and requires identification of Acanthamoeba at the genotypic level. The genus Acanthamoeba consists of both pathogenic and non-pathogenic species and has been recently classified into 13 different genotypes, T1-T12 and T14. More importantly, 95% of Acanthamoeba isolates that produce keratitis belong to T4 genotypes. In this study, we attempted to determine whether predominance of T4 isolates in Acanthamoeba keratitis is due to greater virulence or greater prevalence. We isolated 18 Acanthamoeba isolates from environmental samples in Ankara, Turkey and determined their pathogenic potential by means osmotolerance, temperature tolerance and in vitro cytotoxicity assays using corneal epithelial cells. Ribosomal DNA sequencing revealed that 10 isolates belong to T2, 5 belong to T3, 2 belong to T4 and one belongs to T7 genotype. As expected, T3 and T4 isolates exhibited the most pathogenic traits and were osmotolerant, temperature tolerant and exhibited severe corneal epithelial cell cytotoxicity indicating their pathogenic potential. Overall these data indicate that high frequency of T4 isolates in keratitis cases may well be due to their greater virulence. This is the first report presenting environmental distribution of Acanthamoeba in Ankara, Turkey
Oral findings and its association with prenatal and perinatal factors in newborns
No full textPurpose This study aimed to determine the frequency of abnormalities in the newborn oral cavity and to evaluate the association with prenatal and perinatal factors. Methods This cross-sectional study evaluated 2,216 newborns. Oral findings were assessed in the first 24 hours of life using visual examination. Sex, weight, length, gestational age, and medical disorders at birth were recorded. Maternal demographic and medical information was also obtained. Results The most common oral findings were Bohn’s nodules, Epstein’s pearls, and dental lamina cysts. Other intraoral findings included odontogenic cysts, ankyloglossia, and natal teeth, among others. In logistic regression analyses, folic acid consumption during pregnancy was significantly associated with Bohn’s nodules (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.23–2.55; P=0.002), Epstein’s pearls (OR, 1.63; 95% CI, 1.14–2.33; P=0.007), and dental lamina cysts (OR, 1.45; 95% CI, 1.02–2.05; P=0.038). Moreover, preterm births were negatively associated with prevalence of Bohn’s nodules (OR, 0.63; 95% CI, 0.50–0.80; P≤0.0001). Comparison between newborns with and without oral inclusion cysts showed that maternal folic acid and iron intake were significantly different (P<0.05). Conclusion Maternal folic acid and iron intake were associated with the prevalence of oral inclusion cysts
Reversible mitochondrial respiratory chain impairment during symptomatic hyperlactatemia associated with antiretroviral therapy
No full textDirect evidence confirming the hypothesis that a dysfunction of the mitochondrial respiratory chain (MRC) underlies the pathogenesis of hyperlactatemia associated with highly active antiretroviral therapy (HAART) is scarce. We studied mitochondrial DNA (mtDNA) content and MRC function in the skeletal muscle of an HIV-infected patient during an episode of symptomatic hyperlactatemia. Skeletal muscle biopsy was performed during the episode when the patient was symptomatic and 3 months later when the patient was clinically recovered. Assessment of mitochondria was performed using histological, polarographic, spectrophotometrical, and Southern blot and real time PCR DNA quantification methods. The histological study disclosed extensive mitochondrial impairment in the form of ragged-red fibers or equivalents on oxidative reactions. These findings were associated with an increase in mitochondrial content and a decrease in both mitochondrial respiratory capacity and MRC enzyme activities. Mitochondrial DNA content declined to 53% of control values. Mitochondrial abnormalities had almost disappeared later when the patient became asymptomatic. Our findings support the hypothesis that MRC dysfunction stands at the basis of HAART-related hyperlactatemia
The Design of a Motorized Palm Portable Harvesting Tool using a Flexible Shaft
No full textDalam dunia industri perkebunan, untuk mendapatkan hasil panen yang maksimal, faktor utama yang perlu diperhatikan adalah cara pemanenannya. Proses pemanenan yang efisien, murah dan efektif menjadi hal utama yang harus dicapai. Indonesia sebagai salah satu Negara penghasil sawit dunia bersama dengan Badan Pengelola Dana Perkebunan Kelapa Sawit (BPDPKS) terus mengembangkan cara untuk mengoptimalkan proses produksi sawitnya. Proses pemanenan saat ini masih banyak menggunakan cara manual menggunakan sabit dan dodos. Beberapa alat panen sawit juga ada yang sudah bermotor akan tetapi alat yang ada mempunyai kelemahan dari segi harga dan getaran pada shaft. Pada artikel ini dengan menggunakan metode Quality Function Deployment (QFD) penulis berhasil merancang alat pemanen sawit bermotor dimana getaran dari motor dapat dikurangi dengan memindahkan posisi motor menggunakan Flexible shaft. Selanjutnya memodifikasi gearbox dari material, bentuk roda gigi, dan beberapa element mesin proses itu membuat gearbox menjadi ringan dan memiliki getaran yang kecil. Penelitian ini bertujuan untuk membuat alat panen sawit bermotor yang dapat digunakan untuk memanen buah sawit secara cepat dan mudah. Hal lain yang dituju adalah mendapatkan mesin panen sawit bermotor yang murah karena semua part yang dirancang dan diproduksi pada mesin panen sawit ini dibuat secara mandiri dan memiliki getaran yang rendah. Percobaan yang dilakukan di Koperasi Jasa Profesi (KJP) Cipta Prima Sejahtera Banjarmasin mendapatkan mesin panen sawit yang sudah dirancang memiliki nilai percepatan getaran yang rendah, memiliki perawatan mudah., lebih ringan dibandingkan alat potong sawit bermotor yang sudah ada, dan kecepatan pemotongan dahan yang banyak dan cepat dibandingkan alat potong manual dodos.In the world of the plantation industry, to get a maximum harvest, the main factor that needs to be considered is the way of harvesting. An efficient, inexpensive, and effective harvesting process is the main thing that must be achieved. Indonesia as one of the world's palm oil-producing countries together with the Palm Oil Plantation Fund Management Agency (BPDPKS) continues to develop ways to optimize its palm oil production process. The harvesting process today still uses many manual methods using sickles and dodos. Some palm oil harvesting tools are already motorized, however, existing tools still have disadvantages in terms of price and vibration in the shaft. In this article, the author successfully applied the Quality Function Deployment (QFD) method and designed a motorized palm harvester where vibrations from the motor can be reduced by moving the motor's position using a Flexible shaft. Further modifying the gearbox from the material, gear shape, and some elements of the process engine makes the gearbox lightweight and have a small vibration. This study aims to make a motorized palm harvesting tool that can be used to harvest palm fruit quickly and easily. Another thing to aim for is to get a cheap motorized palm oil harvesting machine because all the parts are designed and produced independently and have low vibration. Experiments conducted at the Professional Services Cooperative (KJP) Cipta Prima Sejahtera Banjarmasin obtained a palm oil harvesting machine that had been designed to have a low vibration acceleration value, has easy maintenance, is lighter than existing motorized palm cutting tools, and the speed of cutting branches is many and fast compared to manual dodos cutting tools
Rapid recycling of coral mass-spawning products in permeable reef sediments.
No full textDuring the annual synchronous release of gametes by corals, a large amount of energy-rich organic material is released to the reef environment. In November 2001, we studied a minor spawning event at Heron Island in the Great Barrier Reef (GBR), Australia. Laboratory experiments showed that egg release by the staghorn coral Acropora millepora amounted to 19 ± 15 g dry mass (mean ± SE, n = 8) per m2 coral surface. Carbon content reached 60.1 ± 4.0% and nitrogen content 3.6 ± 0.4% of the egg dry mass. During this minor spawning period, Acropora corals from the reef crest released 7 g C and 0.4 g N as eggs m-2 reef. In situ experiments (n = 11) using stirred benthic chamber measurements revealed that the sedimentary O2 consumption (SOC) of the lagoon sediments increased sharply immediately after the coral spawning. Extreme SOC rates of 230 mmol O2 m-2 d-1 were reached 2 d after the event, exceeding the pre-spawning rate by a factor of 2.5. This maximum was followed by a steep decrease in SOC rates that gradually levelled off and reached pre-spawning values 11 d after the event. The immediate and strong response of SOC shows that the coral spawning event provides a strong food impulse to the benthic food chain. Our results demonstrate high decomposition efficiency of permeable carbonate reef sands and underline the role of these sediments as a biocatalytical recycling system in the oligotrophic reef environment

Evaluación de la contaminación atmosférica exterior por pm, o3 y co sobre la concentración de pigmentos fotosintéticos en Mangifera indica L. Y Tabebuia rosea
No full textLa contaminación atmosférica exterior es una problemática ambiental que afecta la salud humana y el medio ambiente, especialmente en áreas urbanas. Este estudio evaluó el efecto de la contaminación en las concentraciones de pigmentos fotosintéticos en las especies Tabebuia rosea y Mangifera indica L en un área con alto tráfico vehicular (Escuela de Policía Antonio Nariño) y otra con bajo tráfico (Parque Las Tres Ave Marías), durante las épocas lluviosa (septiembre-noviembre de 2019) y seca (diciembre de 2019 - febrero de 2020). Los datos meteorológicos y las concentraciones de material particulado (PM10 y PM2.5), ozono troposférico (O3) y monóxido de carbono (CO), fueron proporcionados por EPA Barranquilla Verde. La concentración de pigmentos fotosintéticos clorofila a, clorofila b y carotenoides fue determinada por espectrometría a longitudes de onda de 664, 649 y 470 nm, respectivamente. Los resultados mostraron que el CO tuvo picos en época lluviosa en áreas de mayor tráfico, mientras que el PM alcanzó concentraciones más altas en época seca. El O₃ presentó poca variabilidad entre las estaciones. La clorofila a presentó mayores concentraciones en Tabebuia rosea en la época lluviosa, mientras que los carotenoides se mantuvieron estables en ambas especies. Las correlaciones revelaron que altos niveles de O₃ afectan negativamente la fotosíntesis en Tabebuia rosea. Estos hallazgos sugieren que Tabebuia rosea y Mangifera indica pueden utilizarse como biomonitores de calidad del aire, proporcionando una base para futuros estudios y estrategias de reforestación que promuevan la conservación y mejoren la calidad del aire en el área de estudio.Outdoor air pollution is an environmental problem that affects human health and the environment, especially in urban areas. This study evaluated the effect of pollution on the concentrations of photosynthetic pigments in the species Tabebuia rosea and Mangifera indica L. in an area with high vehicular traffic (Antonio Nariño Police School) and another with low traffic (Las Tres Ave Marías Park), during the rainy (September-November 2019) and dry seasons (December 2019 - February 2020). Meteorological data and concentrations of particulate matter (PM10 and PM2.5), tropospheric ozone (O3), and carbon monoxide (CO) were provided by EPA Barranquilla Verde. The concentration of photosynthetic pigments chlorophyll a, chlorophyll b, and carotenoids was determined by spectrometry at wavelengths of 664, 649, and 470 nm, respectively. The results showed that CO peaked during the rainy season in areas with high traffic, while PM reached higher concentrations during the dry season. O₃ showed little variability between seasons. Chlorophyll showed a higher concentration in Tabebuia rosea during the rainy season, while carotenoids remained stable in both species. Correlations revealed that high levels of O₃ negatively affect photosynthesis in Tabebuia rosea. These findings suggest that Tabebuia rosea and Mangifera indica can be used as air quality biomonitors, providing a basis for future studies and reforestation strategies that promote conservation and improve air quality in the study area.Lista de tablas 8--Resumen 6--Introducción 14--Planteamiento del problema 17--Justificación 20--Objetivos 23--Marco teórico 24--Contaminación del aire 24--Contaminantes atmosféricos 25--Biomonitoreo de calidad de aire 34--Pigmentos fotosintéticos 36--Clorofila 37--Carotenoides 39--Estado del arte 41--Metodología 47--Área de estudio 47--Diseño de muestreo 49--Periodo y frecuencia de muestreo 49--Especies seleccionadas 49--Elección y ubicación de los puntos de muestreo 52--Fase de campo 53--Identificación y selección de las hojas 53--Toma de muestras 54--Fase de laboratorio 55--Extracción de los pigmentos fotosintéticos 55--Lectura por método de espectrofotometría 55--Lector de microplacas Berthold multimodo TriStar² S LB 942 56--Cálculo de las concentraciones de los pigmentos fotosintéticos 57--Información de contaminantes atmosféricos y parámetros meteorológicos 58--Fuente de datos 58--Validación de datos 58--Análisis estadístico 59--Estadística descriptiva 59--Correlación de Spearman 60--Resultados y discusión 61--Reporte de variables estudiadas 61--Parámetros meteorológicos 62--Contaminantes atmosféricos 73--Pigmentos fotosintéticos 89--Correlación de pigmentos fotosintéticos con contaminantes atmosféricos 97--Las especies evaluadas como biomonitores de calidad de aire 108--Conclusiones 109--Recomendaciones 112--Referencias 114Ingeniero(a) CivilPregrad
