Authors: Rivera Esteban Jesus M. , Valverde Alva Miguel A. , Aldama Reyna Claver W. 
Published: July 2019

Coloides con nanopartículas esféricas de plata fueron obtenidos por la técnica de ablación con láser pulsado en líquidos. Los parámetros del láser para la síntesis fueron: longitud de onda de 1064 nm, duración de pulso láser de 10 ns, energía por pulso de 15.7 mJ, 2400, 3600 y 4800 pulsos láser. La radiación láser infrarroja fue enfocada por una lente convergente sobre la superficie de un blanco de plata sumergido en agua desionizada. Para la síntesis de los coloides se utilizó el modo de disparo manual de láser. Cada coloide sintetizado (muestra referencia) fue post irradiado con el mismo láser considerado para la síntesis, pero con energía incidente de 8.3 mJ. Para la post irradiación se consideró una razón de repetición de 10 Hz y diferentes números de pulsos. Durante la post irradiación, el rompimiento óptico del coloide se produjo a mitad de altura del mismo. La caracterización de los coloides se realizó con las técnicas de espectroscopia ultravioleta-visible y microscopia electrónica de barrido. Las curvas para el máximo de absorción y la integral del espectro de absorción en el intervalo correspondiente al infrarrojo cercano (desde 600 nm a 800 nm) sugieren que conforme se incrementó el número de pulsos láser considerados para la post irradiación de una muestra referencia, se presentó: ablación y fragmentación denanopartículas hasta un tamaño crítico, agregación, aglomeración y sedimentación de nanopartículas. Se encontró una dependencia entre las propiedades ópticas de nanopartículas de plata con las condiciones de síntesis y post irradiación de coloides con láser pulsado y enfocado.

Published: July 2019

Tulisan ini membahas tentang masjid yang berfungsi juga sebagai museum. Hal ini disandarkan pada pemiikiran bahwa pendidikan Islam moden akan menjadi lebih berkesan apabila digunakan melalui mekanisme muzium. Pengkaji moden telah mengakui hal ini sehingga mereka menekankan peri pentingnya diterapkan pedagogi pendidikan berasaskan muzium. Keberkesanan ini berpunca daripada kelebihan pendidikan berasaskan muzium yang memungkinkan pengunjung memahami sesuatu fakta melalui pembuktian objek/artifak dan bukannya secara teori absrak sepertimana dipelajari di sekolah. Jadi, berasaskan pada latarbelakang ini, kajian ini akan melihat sumbangan MMSAPP (Muzium Masjid Sultan Abdullah Pekan Pahang) yang dianggap sebagai semi institusi pendidikan dalam memperkasakan pemikiran Islam. Sifatnya agak unik memandangkan MMSAPP adalah satu-satunya institusi muzium Islam yang membawa konsep muzium–masjid.

Published: July 2019

Objective: The mean incidence of back pain in pregnant women
very often as compared to non-pregnant women of the same ages. In this study,
we aimed to investigate the frequency of low back pain during pregnancy in
newly delivered mothers who had no predisposing factors for low back pain.

Methods:
83 newly delivered women were included fort he study who are having a normal pregnancy, no history of back/low
back/hip pain requiring hospital admission or medication, no history of
hospital admission during pregnancy except for the last delivery, being a
housewife, and delivering a single baby at term.A questionnaire
including demographic and clinical characteristics were applied to
participants.

Results:
51.8% of all mothers
declared experiencing pain in at least one of the anatomical regions including
back, low back, hip, and posterior pelvic area during the last pregnancy. No
significant difference was determined
between pain an no pain group in term of age, pre-pregnancy and prenatal body
weights/body mass index, weight gain during pregnancy, number of
pregnancy, age of marriage/first live birth, delivery mode. Neonatal height was significantly greater in the mothers with pain
compared to the mothers with no pain, although no significant difference was
found with regard to neonatal weight and gender. A very significant
relationship was found between the presence of pain during a previous pregnancy
and during the last pregnancy

Conclusions:
Pregnancy-related low back
pain is a common health problem among pregnant women, even in women with no
history of predisposing factors for low back pain.
The sporophytic type of fertility restoration in the A3 CMS-inducing cytoplasm of sorghum and its modification by plant water availability conditions
Authors: Elkonin L. A. , Kozhemyakin V. V. , Tsvetova M. I. 
Published: July 2019

The A3 type of CMS in sorghum is one of the most difficult to restore fertility because of the low frequency of fertilityrestoring genes among sorghum accessions, the complex mechanism of fertility restoration that occurs with the complementary interaction of two gametophytic genes Rf3 and Rf4, and the sensitivity of their expression to air and soil drought. In order to test the hypothesis of the sporophytic type of fertility restoration in CMS lines with A3 type cytoplasm developed in our laboratory, we analyzed segregation in the self-pollinated progeny of fertile F1hybrids grown under different water availability conditions (in a dryland plot, in plots with additional irrigation, in a growth chamber, and in an experimental field with a natural precipitation regime) and in their backcrosses to the maternal CMS-line. The presence of sterile plants in the F2 and BC1 families with the maternal CMS line grown in all tested water availability conditions argues for the sporophytic mechanism of fertility restoration. Cytological analysis of fertile F1 hybrids revealed a significant amount of degenerating pollen grains (PGs) with impaired starch accumulation and detachment of the PG contents from the cell wall. It is assumed that the expression of the fertility-restoring genes Rf3 and Rf4 in the hybrids with studied CMS lines starts already in the sporophyte tissues, normalizing the development of a certain part of the PGs carrying the recessive alleles of these genes (rf3 and rf4), which are involved in fertilization and give rise to sterile genotypes found in F2 and BC1 families. For the first time, the transgenerational effect of water availability conditions of growing a fertility-restoring line on male fertility of the F2 generation was detected: a pollinator grown in a plot with additional irrigation produced more fertile and less sterile individuals compared to the same pollinator grown under a rainfall shelter (p < 0.01), and the segregation pattern changed from digenic to monogenic, indicating heritable inhibition of the expression of one of the fertility-restoring genes (kind of “grandfather effect”). The possibility of selection for the stability of the fertility restoration system of the A3 cytoplasm to functioning under conditions of high vapor pressure deficit during the flowering period was shown. These data may contribute to the creation of effective fertility restoring lines for this type of CMS in sorghum.

Published: July 2019

Antecedentes: poco se ha escrito acerca de los efectos de la expansión del Seguro Popular (SP), el programa de salud universal —según afirma el gobierno mexicano—, sobre los recursos humanos y materiales requeridos para satisfacer la nueva demanda. En este artículo analizamos esta pieza clave en la búsqueda de un sistema universal de atención a la salud.Metodología: a diferencia de las evaluaciones previas, en este trabajo utilizamos las jurisdicciones sanitarias como unidades de análisis y operacionalizamos la intervención del SP como un tratamiento continuo (relativo al número de beneficiarios potenciales).Resultados: según lo sugieren las estimaciones, realizadas con base en una variedad de aplicaciones del método de pareamiento por puntaje de propensión, el SP ha tenido un impacto promedio efectivamente positivo sobre los recursos de salud de México. Sin embargo, los efectos de tratamiento cuantil y de interacción revelan resultados inesperados del programa sobre la distribución de recursos sanitarios.Conclusiones: en general, nuestros resultados sugieren la posibilidad de que el programa no esté cubriendo suficientemente algunas de las zonas geográficas más vulnerables del país.
Effect of Bottom Ash and Cow Manure Compost on Chemical Properties of Soil at New-Established Rice Field

Published: July 2019

<p class="Default">The conversion of dryland to rice field at Sumatra Island, Indonesia was generally developed on marginal lands with Ultisols and Oxisols soil types. Those soil types contained high iron (Fe) and aluminum (Al), but low phosphorus (P) and potassium (K). That is because the changes in the process resulted from submerging the soil. For example, the decrease of redox potential, ion reduction from Fe<sup>3+</sup> to Fe<sup>2+</sup>, and Mn<sup>4+</sup> into Mn<sup>2+</sup>. Those compounds will be dissolved and can be absorbed by plants thus causing toxicity. The objective of the study was to assess the effects of bottom ash and cow manure compost at the various doses on soil chemical properties and rice yield on the new-established rice field. This research used factorial design with two factors in Completely Randomized Design. The factors were a dose of bottom ash and cow manure compost, with three replications. The results showed. The addition of bottom ash and cow manure compost at the dosage in this study was not able to reduce the levels of FeDTPA and MnDTPA at newly established rice fields. However, the application of cow manure compost significantly increased soil pH, exchangeable cation (K, Na, Ca), base saturation and decreased exchangeable-H. The addition of bottom ash does not affect paddy yield, while cow manure compost up to 10 tons ha-1 increased panicle and straw dry weight.</p>

Stimulation of Calcite-Rich Shales Using Nanoparticle-Microencapsulated Acids
Authors: Singh Robin , Tong Songyang , Panthi Krishna , Mohanty Kishore K. 
Published: July 2019

Summary
Acid treatment is a common stimulation technique to increase the conductivity of calcite–rich reservoirs. Retarded acid systems such as acid–in–oil emulsions are typically used to minimize wellbore damage and long–distance propagation of acids from the wellbore. However, the stability of these emulsions under harsh reservoir conditions is still a challenge. This study investigates a novel, robust acid carrier system using silica nanoparticles (NPs) for acid treatment of calcite–rich shales. First, highly hydrophobic silica NPs were blended with concentrated acid solutions (0.5–15 wt%) to form acid–in–air powder or microencapsulated acid (MEA). The MEA was then placed in an unpropped fractured core system, and fracture closure was simulated by increasing the overburden pressure. It resulted in the mechanical crushing of the MEA and release of the acid. The conductivity of the cores before and after the MEA treatment was measured. Finally, the surface etching on the fracture face caused by acid was quantified by measuring the surface roughness using an optical profilometer. The qualitative characterization was performed using optical microscopy. The mixing of highly hydrophobic silica NPs with acids under high shear rates resulted in the formation of MEA by self–assembly of the NPs at the water/air interface. These MEA particles were found to be robust encapsulating agents for acids where the release could be triggered by means of mechanical crushing. The fracture–conductivity experiments showed that the MEA could dramatically improve (up to 40 times) the permeability of the unpropped fractures by creating concentration–dependent, nonuniform localized surface etching.
Day centres for older people: attender characteristics, access routes and outcomes of regular attendance. Finding of exploratory mixed methods case study research.
Authors: Orellana Katharine , Manthorpe Jill , Tinker Anthea 
Published: July 2019

Abstract
BACKGROUND
Social prescribing is encouraged to promote well-being, reduce isolation and loneliness. Traditional, generalist day centres for older people could be suggested by social prescribing, but little is known about their clientele or their outcomes. As part of a larger study of the role, outcomes and commissioning of generalist English day centres for older people, the characteristics of attenders at four day centres, their reasons for attendance and outcomes were explored.
METHODS
This mixed-methods study used qualitative interviews and standardised tools within an embedded multiple-case study design. Semi-structured interviews with older day centre attenders (n=23, 62% of eligible attenders) of four day centres in south-east England, recruited purposively to reflect organisational differences, were analysed.
RESULTS
Participants reported non-elective withdrawal from socialisation following health or mobility decline, or losses. Apart from living arrangements and marital status, attenders’ profiles differed between centres. Access had been mostly facilitated by others. Day centre attendance enhanced quality of life for this group of socially isolated people with mobility restrictions and at risk of declining independence and wellbeing. The positive impact on attenders' social participation and involvement and on meaningful occupation was significant (p-value <0.001, 99% CI), with an average ASCOT gain score of 0.18. Nine outcome themes were identified, with a further theme of process outcomes.
CONCLUSIONS
Outcomes of day centre attendance are those targeted by social care and health policy. Centres were communities that ‘enabled’ and offset loss or isolation, thus supporting ageing in place through wellbeing and contributed something unique to their attenders’ lives. By monitoring attenders’ health and wellbeing and providing practical support, information and facilitating access to other services, centres offered added value. Attendance needs to be set in the context of other social engagement and care provision which may not overlap or duplicate centre support. Professionals may wish to explore the benefits of social prescriptions to day centres but should map local centres’ provision, engage with their organisers, and seek information on attenders, who may differ from those in this study.

Published: July 2019

Abstract
Background: Higher C-reactive protein (CRP) levels have been proposed as a predictor of all-cause mortality in many existing studies from multiple populations, but the association for the oldest old adults (aged 80 and older) remains unclear.
Objective: To examine the association between CRP and all-cause mortality among the oldest old Chinese adults.
Design: This is a prospective, community-based longitudinal cohort study with 2206 adults aged 80 years old and older with available CRP test results. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) with 95% confidential intervals (95% CIs) for all-cause mortality according to CRP quartiles, adjusting for potential confounders.
Results: The median age of the participants was 93 years old, and the median CRP concentration was 1.13 mg/L at baseline. During a median follow-up period of 36.7 months, 1106 deaths were verified. After full adjustment for potential confounders, a high CRP concentration was positively associated with an increased risk of all-cause mortality. Compared with the lowest quartile, the fully adjusted HRs of the second, third, and fourth quartiles were 1.17 (95% CI: 0.94, 1.46), 1.28 (95% CI: 1.01, 1.61), and 1.50 (95% CI: 1.20, 1.87), respectively. The association of CRP with all-cause mortality was likely modified by smoking status (P = 0.011).
Conclusions: Our study indicated that a high CRP concentration was likely to be a prospective factor predicting death among the oldest old adults. Future studies investigating additional factors of disease and aging processes are needed to obtain a better understanding of the mechanisms.

Published: July 2019

Abstract
Background

Considering the lack of specific measurement tools to study elders' perceptions in outdoor spaces, the study objectives were to derive and validate a questionnaire that assesses the essential features of elderly-friendly urban spaces.

Methods

We used closed-ended questions in two phases. In the first qualitative phase, a preliminary questionnaire was defined using grounded theory. In the second phase, the psychometric properties of the elderly-friendly urban spaces were examined through validity and reliability indices.

Results

The findings of the first phase led to a preliminary item extraction and questionnaire with 15 major domains based on three dimensions: place function, place preferences, and process. In the second phase, a 48-item questionnaire, based on three dimensions, in addition to personal characteristics, was introduced.

Conclusions

The Elderly-Friendly Urban Spaces Questionnaire (EFUSQ) can be adopted in various communities in understanding of how to create elder-friendly urban spaces to promote active aging.
Utility of conventional aortic root shot angiography for SAPIEN 3 prosthesis sizing in TAVI – feasibility and inter-reader variability
Authors: Gansera Laura , Ulm Bernhard , Bramlage Peter , Krapf Stephan , Oertel Frank , Mueller-Honold Tobias , von Scheidt Wolfgang , Thilo Christian 
Published: July 2019

Abstract
Objectives

We aimed to investigate whether conventional aortic root angiography (CA) alone can reliably facilitate valve selection, and to describe its inter-reader variability.

Background

The gold standard approach to prosthesis sizing before transcatheter aortic valve implantation (TAVI) is multi-slice computed tomography (MSCT).

Methods

Five TAVI specialists (three interventional cardiologists and two cardiac surgeons) independently reviewed pre-procedural CAs for 50 patients implanted with the Edwards SAPIEN 3 valve.

Results

The prosthesis size selected based on visual CA appraisal matched that based on MSCT in 60% of cases (range: 50–68%), with undersizing in 11% (4–33%) and oversizing in 29% (10–46%; p=0.187 for equality of proportions test). Agreement between CA-based and MSCT-based valve selection was moderate (K=0.41; Kw=0.61). Reassessment of choice following awareness of the annulus long-axis diameter did not significantly improve this agreement (0.40 and 0.63, respectively), though more undersizing (14%) and less oversizing (25%) occurred. Correct valve selection was more common in interventional cardiologists than cardiac surgeons (66% vs. 53%; p=0.0391), who made more oversizing errors.

Conclusions

There is modest agreement between CA-based and MSCT-based SAPIEN 3 selection. While the former should not be performed routinely, it may be informative in settings where MSCT and transesophageal echocardiography are unavailable.
