Authors: Nurmutiazifah A , Yuniasih Aisyah Fitri
Published: January 2021

Pendidikan menjadi faktor penting dalam pembentukan modal manusia. Pendidikan yang berkualitas dan merata akan meningkatkan modal manusia, memperluas kesempatan kerja dan meningkatkan kesejahteraan masyarakat. Salah satu indikator yang dapat digunakan untuk menilai kualitas pendidikan yakni rata-rata lama sekolah (RLS). Indonesia dalam Human Development Report 2019 berada di peringkat terendah di antara negara anggota ASEAN 5 untuk RLS. Jika dikaji lebih lanjut berdasarkan kawasan maka KTI memiliki RLS yang lebih rendah dari RLS KBI dan RLS nasional. Jika masalah kualitas pendidikan dan tidak meratanya pendidikan di Indonesia khususnya di KTI tidak segera diatasi, maka 90 persen masyarakat miskin yang bertempat tinggal di Indonesia (bersama Filipina) khususnya di KTI akan terus terjerat dalam lingkaran kemiskinan karena tidak mampu meningkatkan kesejahteraan hidupnya.Metode yang digunakan dalam penelitian ini adalah analisis regresi panel untuk menjelaskan determinan ketimpangan capaian pendidikan di KTI. Jenis data yang digunakan berupa data panel dengan cross-section sebanyak 17 provinsi dari tahun 2015-2019. Berdasarkan hasil regresi dengan metode estimasi FGLS/SUR diperoleh bahwa investasi, distribusi guru dan akses pendidikan berpengaruh negatif signifikan, sedangkan remaja menikah muda dan ketimpangan distribusi pendapatan berpengaruh positif signifikan terhadap ketimpangan capaian pendidikan.

Introduction: The detrimental effects of cigarette smoking include impairment of optic nerve head perfusion and elevation of oxidative stress levels, which are believed to be part of the pathogenesis of glaucoma. However, there is no evidence on the effect of cigarette smoking as a risk for primary angle-closure glaucoma (PACG).
Purpose: To determine the association between cigarette smoking and PACG in Malay patients.
Study design: Case control study.
Materials and methods: Two-hundred Malay PACG patients and 250 controls from  three tertiary hospitals in Malaysia were involved in this study. PACG patients were diagnosed based on the World Glaucoma Association consensus. The smoking status was documented using validated questionnaire adopted from Singapore Malays Eye Study through face-to-face interview. Smoking status was divided into active smokers, ex-smokers, passive smokers, and non-smokers. The association of smoking and PACG was analysed with multiple logistic regression. Confounders such as age, gender, education status, and body mass index (BMI) were considered in the analysis.
Results: There was female preponderance in PACG with 3:1 ratio. Active smokers (p = 0.656) and ex-smokers (0.073) were not significantly associated with PACG in Malays. Passive smoking significantly increased the risk of PACG by 6.8-fold (95% CI 2.49,18.67; p < 0.001). Number of cigarettes/day (p = 0.144) and duration of smoking (p = 0.176) were also not significantly associated with PACG (p = 0.144). No formal education, primary and secondary education level increased the risk of PACG (p < 0.001). Each unit increment of BMI increased the risk of PACG by 1.14-fold (95% CI 1.03, 1.27; p = 0.014). A year increased in age increased the risk by 1.05 times (95% CI 1.00, 1.09; p = 0.026).
Conclusions: There is no significant association between active smoking and PACG. Passive smoking is a potential risk factor for PACG. The preponderance of women may contribute to this result. However, quantification of exposure to passive smoking is not possible in this study.
Ocular biometry and refractive changes post sutureless vitrectomy surgery
Authors: Raja othman Raja nor farahiyah
Published: January 2021

Introduction: Pars plana vitrectomy (PPV) without endotamponade should not induce significant change to the refractive status of the eye. However, several studies have reported minor refractive changes after plain vitrectomy. Purpose: To compare the changes in refraction following PPV and to examine the biometry parameters that may affect the refractive change.Materials and methods: In this prospective cohort study, patients who were listed for 23-gauge 3-port PPV without buckling or silicone oil tamponade were enrolled between December 2015 and September 2017. Autorefraction, keratometry, anterior chamber depth (ACD), and axial length (AL) were measured preoperatively and three months postoperatively.Results: This study involved 41 eyes from 38 patients. The mean spherical equivalent (SE) before PPV was -1.08 dioptres (D), (standard deviation (SD) 2.18), which changed to a mean of -1.88 D (SD 2.20) postoperatively. The mean SE change was -0.80 D (SD 1.61, 95% confidence interval (CI) -1.31 to 0.30 D, P = 0.003). The median astigmatism before PPV was 0.69 D (Interquartile range (IQR) 0.69 D) reduced to 0.66 D (IQR 0.60 D) after PPV (P = 0.882). Median ACD preoperatively was 3.55 mm (IQR 0.76 mm) and reduced postoperatively to 3.44 mm (IQR 0.67 mm), (P = 0.028). The median AL was 23.36 mm (IQR 1.42 mm) and 23.48 mm (IQR 1.56 mm) before and after PPV, respectively, (P = 0.029). No significant SE change was found between phakic and pseudophakic groups (P = 0.155).Conclusion: Patients experience myopic shift post plain PPV, possibly due to the reduction of ACD. The ACD tended to be shorter in the pseudophakic group, suggesting that the myopic shift in the phakic group may be a result of the development of nuclear sclerosis cataract.

Published: January 2021

Introduction: Corneal arcus and eyelid xanthelasma are the common ocular findings but not exclusively found in familial hypercholesterolaemia (FH) patients. Low density lipoprotein receptor (LDLR) gene is the one of the most common genes investigated in FH. There is no study predicting ocular manifestations with genetic variations of the LDLR gene.Purpose: To associate common ocular manifestations of FH and LDLR gene in Malays.Material and methods: A cross-sectional study involving 50 unrelated Malay patients with FH were recruited. FH was diagnosed based on Dutch Lipid Clinic Network diagnostic criteria. The right eye was examined for eyelid xanthelasma and corneal arcus, while mean retinal nerve fibre layer thickness (RNFL) was assessed using Heidelberg retinal tomography II. Venepuncture was performed and genomic deoxyribonucleotide acid (DNA) was extracted. LDLR gene variations were screened using denaturing high-performance liquid chromatography and confirmed through DNA sequencing.Results: Corneal arcus was detected in 86.0% of patients, while eyelid xanthelasma was detected in 2.0% of patients. Mean RNFL thickness was 254.16 μm (SD: 60.67 μm). LDLR gene variations were identified in 32 patients (64.0%), including 5 mutations and 9 single nucleotide polymorphisms (SNPs). Two novel mutations were detected: c.1705+117T>G and p.Asp139His. There was significant association between genotype frequency of LDLR variations c.940+36G>A, p.Glu201Lys and p.Asp304Asn with FH, p.Glu201Lys with corneal arcus, and p.Cys255Ser and c.1705+117T>G with mean RNFL thickness.Conclusion: LDLR gene variations were not uncommon in Malay patients with FH. Two novel variations, c.1705+117T>G and p.Asp139His, were identified. LDLR gene is a potential predictor genetic marker for corneal arcus in Malay patients with FH. c.1705+117T>G is associated with thinner mean RNFL thickness.

Published: January 2021

A retrospective case series highlights two cases of postoperative endophthalmitis, in which similar improper technique of puncturing the antibiotic bottle with a nonsterile needle was noted.

Patient A, a 65-year-old man with three weeks’ history of uneventful combined cataract and pars plana vitrectomy (PPV) presented with acute painful right eye and vision blurring from 6/12 to 1/60 for two days. Examination showed severe anterior chamber activity and hazy fundal view. B-scan showed dense vitritis. Vitreous sampling revealed gram positive cocci, but no culture growth. Patient B, a 69-year-old man presented with three days’ history of right painful red eye and vision dropped to light perception following an uneventful cataract surgery. Examination showed severe anterior chamber activity with hypopyon, raised intraocular pressure, and no fundal view. B-scan detected dense vitritis with loculation. Vitreous sampling cultured Pseudomonas aeruginosa in Patient B. In both cases, the patients reported piercing the generic topical ciprofloxacin 0.3% bottle tip with a nonsterile needle instead of the prescribed method of using the sterile, inner aspect of the bottle cap. However, the cultures of the bottle contents were negative in both cases. Both patients received intravitreal, topical, and systemic antibiotics and subsequently underwent PPV. Patient A recovered vision to baseline, while Patient B recovered to counting finger vision.

The cap-puncturing mechanism for eye drop bottles is designed to maintain the sterility of the contents. However, this may backfire when patients do not understand the prescribed technique. We postulate that this improper technique predisposed the two cases to endophthalmitis.
An atypical presentation of ANCA-associated retinal vasculitis in a young Malay woman
Authors: Yap Jin Yi , Ibrahim Mohtar , Embong Zunaina
Published: January 2021

We describe a case of antineutrophil cytoplasmic antibody (ANCA)-associated retinal vasculitis in a 21-year-old previously healthy Malay woman, who presented to us with complaints of sudden painless loss of vision in her left eye. Her vision upon presentation was counting fingers and her fundus examination showed retinal vasculitis and ischemic changes. Fundus fluorescein angiography showed leakage from the vasculitic retinal vessels, resulting in macular oedema. All investigations were normal, except that a full blood test showed eosinophilia and an autoimmune screening revealed positive perinuclear staining-ANCA, which led us to diagnose ANCA-associated retinal vasculitis. The patient was comanaged with the rheumatology team. She was started on a high-dose intravenous steroid followed by a tapering dose of an oral steroid. Improvement was noted from the resolution of macular oedema evident on optical coherence tomography of the macula. However, vision remained poor and unchanged.

Published: January 2021

Mycobacterium tuberculosis is transmitted through aerosolization, hence commonly infects the lungs. The occurrence of extrapulmonary tuberculosis is rare. We report a case of eyelid tuberculosis in a 45-year-old gentleman with a history of treated testicular tuberculosis three years ago. He had insidious onset of painless swelling in the right upper eyelid associated with erythema for one month. He did not have other constitutional symptoms. Initially, he was treated as chalazion and given topical antibiotics. However, the swelling worsened despite medication. His best corrected visual acuity was 6/9 in both eyes. Examination showed an elevated ulcerative growth with broad base which bled easily upon touch. The clinical presentation varies from an eyelid infection as an eyelid tumour can be a diagnostic challenge. A slow response to oral and topical antibiotic warrants an excision biopsy. The results showed chronic granulomatous infection in acid-fast bacilli. An antituberculosis (anti-TB) therapy was started and the patient showed a positive clinical response.

Althrough rare, tuberculosis of eyelid should be considered as differential diagnosis of chalazion. Any suspicious case should be confirmed by biopsy followed by anti-TB if indicated.
Complication of foldable single-piece intraocular lens sulcus implantation in a child under two years old
Authors: Barliana Julie Dewi
Published: January 2021

A two-and-a-half-year-old boy presented to Cipto Mangunkusumo Hospital, Jakarta, Indonesia with a white spot on his left eye. He had cataract surgery one year prior at another hospital. On examination, corectopia, anterior synechiae, white plaque between the iris and corneal endothelium, a shallow anterior chamber, and an intraocular lens (IOL) in the posterior chamber were found. As a result, anterior chamber reformation and IOL explantation was performed.

Intraoperatively, a foldable single-piece IOL was found in the ciliary sulcus. Hence, extreme inflammatory process after the operation was unavoidable. One month after the procedure, the cornea was opaque without an increase in intraocular pressure. It is recommended to perform IOL implantation only in children over two years of age with a corneal diameter more than 9 mm. A three-piece IOL might be implanted in the area of the ciliary sulcus only if the child needs an immediate IOL implant.

Authors: Patrick Sylves , Hui Tze Chan , Abdul Rashid Rasdi , Ahmad Tajudin Liza Sharmini
Published: January 2021

Introduction: Spontaneous retinal venous pulsation (SRVP) is a rhythmic variation in the calibre of one or more retinal veins. The incidence of SRVP was reduced in glaucoma patients. It was also reduced in people with raised intracranial pressure compared to a healthy population.

Purpose: The main objective was to report the frequency and rate of SRVP in primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG) patients and to associate these with the severity of glaucoma in Malay patients.

Design of study: A comparative cross-sectional study.

Materials and methods: A comparative cross-sectional study involving primary glaucoma patients attending the eye clinic at Hospital Universiti Sains Malaysia (HUSM), Kelantan, Malaysia, was performed between December 2015 and June 2017. The main outcomes measured were the presence and rate of SRVP using a confocalscanning laser ophthalmoscope (Spectralis High-Resolution Optical Coherence Tomography Angiography, Heidelberg Engineering GmbH, Heidelberg, Germany). In the presence of SRVP, the rate of SRVP in one minute was counted manually based on the real-time fundus movie recorded using the confocal scanning laser ophthalmoscope.

Results: Thirty-eight POAG, 14 PACG, and 51 control group subjects were included. There was a significantly lower incidence of SRVP in primary glaucoma patients than in the control group (p = 0.003). The presence of SRVP was significantly lower in POAG than PACG (p = 0.04). There was no significant difference in the rate ofSRVP between primary glaucoma patients and the control group (p = 0.873) or between the POAG group and PACG group (p = 0.511). There was no association of incidence (p = 0.574) and rate (p = 0.167) of SRVP according to the severity of glaucoma. Systolic blood pressure (95% CI: 0.95–1.00, p = 0.038) and retinal nervefibre layer thickness (95% CI: 1.01–1.09, p = 0.008) showed a significant association with the presence of SRVP.

Conclusions: SRVP is a potential predictive factor for detection of primary glaucoma. The role of SRVP in the severity of glaucoma is still unclear. The role of SRVP in PACG patients warrants further studies in the future.

Authors: Teh Swee Sew , Ong Poh Yan
Published: January 2021

Purpose: To study the intraocular pressure (IOP)-lowering effects of selective laser trabeculoplasty (SLT) at six months and to determine factors that can predict the success of SLT.

Study design: Prospective cohort study with convenience sampling.

Material and methods: The patients were seen at the Glaucoma Clinic, Selayang Hospital from October 2017 to September 2018. Patients with primary open-angle glaucoma (POAG), normal-tension glaucoma (NTG), and ocular hypertension (OHT) of mild to moderate severity that needed further IOP reduction were recruited. Baseline characteristics were documented followed by water drinking test (WDT) and SLT. Follow-up was scheduled at one week, six weeks, three months, and six months. WDT was repeated at six months.

Results: Eighteen eyes of 18 patients were recruited. IOP at baseline, 1 week, 6 weeks, 3 months, and 6 months was 19.3 ± 3.7,16.7 ± 3.8,16.5 ± 2.7,16.6 ± 3.2 and 15.3 ± 3.8 mmHg, respectively (P < 0.05). The reduction of baseline IOP, peak IOP, and IOP fluctuation were 20.7%, 26.7%, and 31.4%, respectively (P < 0.05). The cumulative success at six months was 44%. The significant success predictors were mean deviation on Humphrey visual field and IOP one week post-SLT.

Conclusions: SLT can be used to treat mild to moderate POAG, NTG, and OHT patients, either as first-line treatment or as an adjunct to medical therapy.

Published: January 2021

Neonatal retinoblastoma is more widely reported in developed countries than in developing countries. We have conducted a retrospective case series to understand the nature of neonatal retinoblastoma in Malaysia due to lack of data from developing countries.

A retrospective record review of 295 patients was conducted from the Retinoblastoma Registry on the National Eye Database (NED) between January 2005 and December 2019. Six out of 295 patients (2.03%) were identified as neonatal retinoblastoma in Malaysia from 2005 until 2019 compared to developed countries, in which the detection rate were 3.5 to 10 times higher.

Lack of awareness among survivor parents about the risk of their newborns developing retinoblastoma in may be a contributing factor. Neonatal retinoblastoma is difficult to manage, thus close and continuous monitoring is needed in centres dedicated to retinoblastoma management.

Ectopia lentis or crystalline lens subluxation is one of the major criteria to diagnose Marfan syndrome. It may vary from mild lens subluxation to lens dislocation. Herewith is a case report of a 4-year-old autistic boy who had never been diagnosed with Marfan syndrome. He presented to the clinic after his parents noticed he had difficulty focusing on near objects. His bilateral best-corrected visual acuity was 6/60. On examination, there was bilateral lens subluxation superotemporally and lens equator blocking his visual axis. He was sent to the paediatric team and further Marfan workout showed dilated aortic root. He was then diagnosed with Marfan syndrome. He underwent bilateral lens aspiration, anterior vitrectomy, and iris-claw lens implantation. His postoperative bilateral visual acuity on day 1 was 6/30 and his best-corrected visual acuity 3 months after surgery was 6/9 for both eyes. In conclusion, ophthalmologists play an important role in diagnosing and managing Marfan syndrome. Early diagnosis is important to help preserve vision and improve quality of life.

This case report aims to discuss a case of tobacco-alcohol optic neuropathy secondary to alcohol abuse and chronic cigarette smoking in a 43-year-old man. Possible causes including vitamin B12 deficiency, methanol poisoning, and cyanide in tobacco were discussed. Clinical examination and blood investigation supported the diagnosis of vitamin B12 deficiency, possibly precipitated by methanol and cyanide. The patient was treated with vitamin B12 and folinic acid and asked to abstain from smoking and alcohol consumption. His left eye vision had improved to premorbid vision but there no improvement on the right eye. As a conclusion, tobacco-alcohol optic neuropathy is a diagnosis of exclusion and treatment shows variable response.
Repeatability and comparability of simulated K values between a grid projection-based device and a Placido/dual Scheimpflug device
Authors: Tagal Julian Matius
Published: January 2021

Purpose: To evaluate the repeatability and comparability of simulated K values obtained by the Galilei G4 Corneal Tomographer and the iDesign Wavefront Abberometer.

Methods: The right eyes of 100 consecutive pre-laser-assisted in situ keratomileusis (LASIK) patients were included in this study. Patients with a history or signs of previous corneal or ocular trauma and infection were excluded. Paired corneal measurements for flat (K1) and steep (K2) meridians were obtained with both the Galilei and the iDesign. Repeatability was evaluated by calculating the coefficient of variation (CV) of the paired measurements. The comparability between platforms was evaluated by calculation of the mean differences followed by the construction of Bland-Altman plots and calculation of limits of agreement (LOA).

Results: While the mean CV for both devices was low (0.17% versus 0.57% for the Galilei and iDesign, respectively), a large proportion of eyes measured by the iDesign (22%) showed an absolute difference of > 0.5 D between paired readings, compared to 1% as measured by the Galilei. The Galilei consistently measured higher than the iDesign. Although the mean difference did not exceed 0.17 D, the LOAs were unacceptablywide at -0.52 D to 0.85 D and -0.69 D to 0.89 D for K1 and K2, respectively.

Conclusion: As regards keratometry, the iDesign demonstrated clinically unacceptable repeatability. Both platforms demonstrated sufficiently wide LOA that we could not recommend that they are used interchangeably.

Forests are biological natural resources that have provided development benefits in Indonesia during their specific “Orde Baru” government of the timber forest product sector, but the impact of high exploitation has had considerable damage. Therefore it is necessary to find alternative efforts in forest utilization. One such effort is to utilize plants that can be used as medicinal plants. Medicinal plants are an alternative use of forest products from the non-timber sector. One of the places that need to know the existence of medicinal plants is Taman Wisata Alam Gunung Tampomas. Lack of data from the types of medicinal plants in this area feared damaged and extinction.The results of this research found 21 species of medicinal plants consisting of 19  types of non-tree vegetation and 2 types of tree vegetation. Non-tree vegetation is dominated by the type of Eupatorium riparium with Relative Frequency of 8.60%. While the tree vegetation was dominated by Melia azedarach species with INP value in each strata of seedlings, piles, poles, and trees respectively 9.02%, 11.97%, 18.14% and 20.43%. Most of the medicinal plants have the benefit of fever, abdominal pain, urine, malaria, bleeding such as Imperata cyindrica, Melia azedarach, Ageratum conyzoides, Quassia amara, Angioptris evecta and Eupatorium ripariumBenefit from this research about existence of medicinal plants in the area of Blok Paseban and Blok Pasir Sabeulah TWA Gunung Tampomas, the community can make this area as a source of germplasm so that the existence of medicinal plants can be preserved sustainability.

Wooden carpets are one of the products made of woody materials glued on the textiles. The wooden part can be in the form of plywood or solid wood, while the textiles as a carpet backing serves as a link between the pieces of woody material that make up the carpet. Compared to fabric carpets, wood carpets have several advantages in terms of health and maintenance. Wood carpet generally include woody material, fabrics, glue and finishing materials. The glue serves as an adhesive between woody material and fabric. The shear strength of glue adhesives has an important role in wood carpet products. In the local market there are several types of glue such as white glue (Polyvinyl Acetate) and yellow glue (Synthetic Rubber). The purpose of this study was to compare the shear strength of white and yellow glue. It is expected that people can choose the type of glue that is more suitable for wood carpets. The research data was tabulated and analysed by paired t-test. The results showed that the shear strength of  white and yellow glue using manual clamps were 27.95 kg cm-2 and 13.78 kg cm-2 respectively. The shear strength of white glue strongly differ with those of yellow glue, and greather two times than the yellow one.   In making or producing wooden carpets, it is recommanded to use white glue instead of yellow one and can apply manual clamps. However, for better results, it is recommended to apply a press machine.

Despues, en la etapa de multiplicación los brotes se sometieron a estrés osmótico en medio líquido con PEG (0, 10, 15 y 20 %) durante tres ciclos de selección de 15 d cada uno. En el primer experimento se cuantificaron características morfo-fisiológicas de los brotes de los ciclos de selección 1 y 3, y se observó efecto significativo de la interacción genotipo x PEG sobre la altura y número de hojas por brote, de genotipo x ciclo sobre número de hojas y biomasa fresca, y de PEG x ciclo sobre el peso fresco. En el segundo experimento se midieron características de los brotes del tercer ciclo de selección, y se encontró efecto significativo del genotipo sobre el peso fresco y seco por brote, así como efecto de PEG sobre el peso fresco y el contenido de agua. La interacción genotipo x PEG fue significativa sobre el potencial hídrico, potencial osmótico y ajuste osmótico total. Las mejores líneas fueron L-14 y L-16 porque tuvieron mayor ajuste osmótico y mejores características morfo-fisiológicas, lo cual muestra que la selección in vitro es viable para elegir genotipos tolerantes.

En México hay amplia diversidad genética y fenotípica del maíz (Zea mays L.) para color de grano debido a la presencia de antocianinas y otros pigmentos. En este estudio se estimaron los efectos maternos (EM) y la aptitud combinatoria general (ACG) que inciden sobre el tamaño del pericarpio y de la capa de aleurona, así como sobre su capacidad para acumular antocianinas, en semilla de la generación F1 de las cruzas posibles entre seis poblaciones criollas de maíz de colores de grano: púrpura (Rojo-1), azul (Azul-1), morado (Azul-2), rojo (Rojo-2), Amarillo y Blanco. Se observó una relación entre el color del grano y el contenido de antocianinas. El progenitor Rojo-1 presentó el mayor contenido de antocianinas (1269 mg kg-1 de grano), del cual 90.2 % se acumuló en el pericarpio; este progenitor superó a los demás progenitores en por lo menos 70.7 %. Hubo diferencias (P ≤ 0.05) entre las 30 cruzas y los seis progenitores en el peso de pericarpio y del grano; en los contenidos de antocianinas en el pericarpio, en la aleurona y en el grano; y en el grosor del pericarpio y de la aleurona. Los EM y la ACG tuvieron la mayor importancia sobre las características estudiadas, y Rojo-1 y Azul-1 fueron los progenitores sobresalientes.

La riqueza hídrica de la zona centro-oriente de Morelos ha permitido el aprovechamiento de los manantiales y del río Cuautla para el establecimiento del cultivo de berro (Nasturtium officinale R. Br.) en el municipio de Cuautla, donde la siembra de esta hortaliza tiene más de 70 años. Sin embargo, es escasa la información sobre el sistema de producción y el impacto económico en la región. El objetivo de esta investigación fue describir aspectos sociales, técnicos y de comercialización sobre el cultivo de berro producido en el municipio de Cuautla, Morelos. La investigación se realizó en el año 2018. Se entrevistó a productores y se realizaron visitas a sus unidades de producción. Lo anterior permitió obtener información sobre aspectos relacionados con la producción, comercialización y beneficios económicos. Los ejidos productores de berro son Cuautla, Cuautlixco y Santa Inés. Existen dos asociaciones y algunos productores independientes, quienes han dispersado esta hortaliza en toda la zona productora, así como su manejo agronómico y centros de venta. La producción de berro en la región no figura en las estadísticas estatales, pero esta actividad agrícola genera beneficios económicos y empleos. La información recabada permitió conocer mejor el sistema de produccción de berro, con lo que se podrán proponer alternativas para un mejor manejo.

Campeche es unos de los principales estados productores de soya (Glycine max L. Merr.) en México, con un rendimiento promedio de 2.6 t ha-1; sin embargo, en éste se tiene una variación significativa en los rendimientos anuales. Algunos autores han asociado estas variaciones a los genotipos, a las fechas de siembra y a su interacción. Por considerar que en este tema existe poca información se realizó este trabajo con el objetivo de estudiar los efectos de cuatro fechas de siembra (19 junio, 10 julio, 2 de agosto y 20 de agosto) durante 2017 y 2018 en el rendimiento de nueve variedades de soya (H100, H200, H300, H400, H600, Tamesí, Vernal, Luziania y Mariana). El experimento se estableció con un arreglo de parcelas divididas en un diseño experimental de bloques completos al azar. Los análisis estadísticos fueron análisis de varianza, pruebas de medias, análisis de componentes principales y de regresión en los sitios (SREG) para las para las interacciones genotipo x ambiente. Las fechas del 19 de junio y 10 de julio tuvieron el rendimiento más alto (3 t ha-1), el cual estuvo asociado con el peso de grano, el número de ramas por planta y el número de semillas por planta. Al retrasar la fecha de siembra se redujo el rendimiento por planta entre 5.7 y 10 g día-1, asociado a una disminución en el peso de grano, número de vainas, semillas y ramas por planta. En las siembras del 19 de junio sobresalió en rendimiento H100 y en la del 10 de julio destacó H200. Las variedades con menores rendimientos fueron Mariana (2.3 t ha-1) y Luziania (2.4 t ha-1). Los resultados de este estudio sugieren que no es recomendable sembrar soya en fechas tardías de agosto en Campeche.

En el cultivo de fresa (Fragaria × ananassa Duch.) la desinfección al suelo es principalmente por métodos químicos. Debido a los potenciales efectos negativos de los desinfectantes químicos hacia el ambiente, actualmente se estudian productos menos agresivos o sistemas alternativos como los cultivos en sustratos; sin embargo, no se cuenta con suficiente información del efecto que estas alternativas tienen sobre el rendimiento de la planta. El objetivo del presente estudio fue evaluar el efecto del sustrato tratado antes de plantación con metam sodio (MS) o mediante inoculación con micorrizas sobre el rendimiento y materia seca acumulada de los cultivares de fresa Zamorana y Festival. Plantas crecidas en sustratos preparados con peat-moss y perlita, con o sin composta y tratados o no con MS o micorrizas se distribuyeron completamente al azar en arreglo factorial 3 × 2 × 2 (tratamiento de sustrato, mezcla de materiales y cultivares) en un invernadero de vidrio. Ni el MS ni las micorrizas afectaron significativamente los componentes de rendimiento ni la distribución de materia seca en los órganos de la planta. La adición de composta al sustrato tampoco afectó el rendimiento ni el número de frutos por planta, pero resultó en menor peso del fruto (11.3 g) en comparación con sustratos sin composta (12.1 g, P < 0.03). También se observó una reducción de 46.0 % (P < 0.0001), 15.2 % (P < 0.00189) y 12.4 % (P < 0.0195) en materia seca acumulada en raíz, hoja y total, respectivamente, en plantas cultivadas con composta. Zamorana tuvo mayor rendimiento y peso de fruto que Festival, con 410.2 vs. 345.5 g/planta (P < 0.006) y 12.8 vs. 10.6 g/fruto (P < 0.0001), respectivamente. La producción de fresa en los sustratos estudiados no requiere tratamiento previo del material y Zamorana muestra mejor potencial que Festival para producción en sustrato por su mayor rendimiento y peso de fruto.

La miel de abeja se ha utilizado desde la antigüedad por sus buenas propiedades nutricionales y terapéuticas. Se produce en todo el mundo y juega un papel importante como agente antioxidante, antiinflamatorio y antibacteriano; también aumenta la adherencia de los injertos de piel y el proceso de curación de heridas. La relación entre el consumo de ciertos alimentos y la salud deriva de la presencia en éstos de una serie de sustancias nutritivas y otras no nutritivas, pero con un papel clave en la prevención de determinadas enfermedades. Los polifenoles son compuestos bioactivos que se encuentran en los alimentos, contribuyen a mejorar diversas actividades fisiológicas, desempeñando un papel antimicrobiano, con propiedades antinflamatorias, antitumorales y anticancerígenas. El objetivo de esta investigación fue determinar la actividad antioxidante y el contenido fenólico total de miel de abeja producida en Zacatecas. Se analizaron cuatro variedades de miel de abeja [multiflora, mezquite (Prosopis laevigata), flor de gatuño (Mimosa spp.) y flor de gatuño cremosa (Mimosa spp.)] en términos de capacidad antioxidante (métodos ABTS•+, DPPH y FRAP) y el contenido fenólico total (método Folin-Ciocalteau) por dos procedimientos de extracción (extracción metanólica y acuosa). Los datos se sometieron a análisis de varianza de una vía. Se encontraron diferencias estadísticamente significativas (P ≤ 0.05) entre las muestras en términos de contenido fenólico total, pH, °Brix y humedad, así como en la capacidad antioxidante por los métodos ABTS•+ y FRAP. La extracción metanólica mostró el contenido fenólico más alto (144 mg of GAE 100 g-1), mientras que la extracción acuosa presentó la mayor capacidad antioxidante cuando fue analizada con el método DPPH (1118.3 μmol equivalentes de Trolox 100 g-1).

En México y a nivel mundial, la demanda de variedades mejoradas de nochebuena (Euphorbia pulcherrima Willd. ex Klotzsch) es dinámica, y por ello se genera gran número de variantes para ofertar 500 millones de plantas al año (Islam y Joyce, 2015). Cada año se comercializan, aproximadamente, 20 millones de plantas de nochebuena en México durante la temporada de navidad. En varias entidades mexicanas se produce nochebuena, entre las que sobresale el estado de Morelos como el principal productor con aproximadamente 6.4 millones de plantas (SIAP, 2019). Las plantas de nochebuena se ofertan en macetas que van de 7.62 a 30.48 cm de diámetro, la más común es la de 17.78 cm (Canul-Ku et al., 2017).

Columbus: aportes de la teledetección y análisis de coste anisotrópico a un debate histórico
Authors: Felicísimo Ángel M.
Published: January 2021

La ruta seguida por la primera expedición de Cristóbal Colón es incierta debido a la ausencia o poca fiabilidad de esta información en el diario del almirante. Los actuales datos procedentes de teledetección y su análisis mediante SIG pueden aportar nueva información mediante análisis de los campos de viento estacionales en la zona. Los resultados del análisis de seis años muestran que el régimen de vientos es homogéneo y que configura dos corredores o pasillos de bajo coste relativo para la navegación a vela con las condiciones de los barcos del siglo XV. De estos dos corredores uno conduce con exactitud al destino al que se cree que llegó Colón el 12 de octubre de 1492 y se presenta como la ruta más probable, algo más al Sur que la propuesta hasta el presente en la bibliografía. Los SIG se muestran como una herramienta capaz de aportar información inédita a partir de datos globales, tomados en este caso por el escaterómetro QuikSCAT, aplicando métodos de análisis espacial poco usados en la literatura científica.
