Juan Rulfo : Su vida, su tiempo y su obra

Sergio Lopez Mena 서울대학교 스페인중남미연구소 2005 이베로아메리카硏究 Vol.16 No.-

En la narrativa mexicana del siglo XX, en la que destacan Mariano Azuela, Martín Luis Guzmán, José Revueltas, Agustín Yáñez, Juan José Arreola y Juan Rulfo, este último sobresale por la autenticidad de su lenguaje y el carácter renovador de sus propuestas literarias. La vida de Rulfo abarca una etapa crucial de la historia contemporánea de México, la de la institucionalización de la Revolución Mexicana, época en que florece culturalmente el nacionalismo. En sus cuentos, expresión de una mentalidad de los hombres del campo, Rulfo construyó con intensidad seres en situación límite, con la violencia como signo más evidente. En su novela Pedro Páramo, está la idiosincrasia de un amplio grupo social, pero además la profundización en los misterios del hombre universal, particularmente en la veta de la pasión amorosa. Novela dialógica, desprovista del tradicional punto de vista moralizante, es Pedro Páramo una obra auténtica, de fina poesía. Por otra parte, la obra fotográfica de Rulfo, que lo muestra como un experto en ese arte, da testimonio del México de todos los tiempos, con la pobreza de su gente, la aridez de sus campos, la ternura de sus indígenas.

Efficacy of topical interventions for temporomandibular disorders compared to placebo or control therapy: a systematic review with meta-analysis

Mena, Mariam,Dalbah, Lana,Levi, Lauren,Padilla, Mariela,Enciso, Reyes The Korean Dental Society of Anesthsiology 2020 Journal of Dental Anesthesia and Pain Medicine Vol.20 No.6

This systematic review focused on the efficacy of topical products in reducing temporomandibular joint disorder (TMD)-associated pain, in comparison to placebo or control interventions. The EMBASE, Web of Science, Cochrane Library, and MEDLINE via PubMed databases were searched for randomized controlled trials (RCTs) using topical interventions in adults diagnosed with TMD. The pain intensity was the primary outcome, and other clinical findings were the secondary outcomes. The risk of bias was evaluated according to the Cochrane's handbook. The search up to February 7, 2020 identified a total of 496 unduplicated references. Nine RCTs with 355 adult patients diagnosed with TMD were included. The meta-analysis did not show a significant reduction in baseline pain intensity in the nonsteroidal anti-inflammatory drug (NSAIDs) group, when compared to the placebo group (P = 0.288). One study demonstrated a statistically significant pain score decrease for Theraflex-TMJ compared to placebo after 10 d of treatment (P = 0.003) and follow-up, 5 d after the last application (P = 0.027). Ping On reduced pain at 4 weeks of application (P < 0.001) but not after 7 d of application (P = 0.136). In one study, cannabidiol (CBD) significantly improved the pain intensity compared to placebo (P < 0.001). However, no differences were found with capsaicin in the two studies (P = 0.465). Evidence was of low quality because the studies were considered as having an unclear or a high risk of bias and a small number of studies were analyzed. The evidence is not sufficient to support the use of topical NSAIDs and capsaicin, and limited evidence was found for Threraflex-TMJ, bee venom, Ping On, and CBD, with only one study reporting for each. Additional studies are recommended to validate these results.

The quantum universe: philosophical foundations and oriental medicine

Menas Kafatos,Keun-Hang Yang 한국한의학연구원 2016 Integrative Medicine Research Vol.5 No.4

The existence of universal principles in both science and medicine implies that one can explore their common applicability. Here we explore what we have learned from quantum mechanics, phenomena such as entanglement and nonlocality, the role of participation of the observer, and how these may apply to oriental medicine. The universal principles of integrated polarity, recursion, and creative interactivity apply to all levels of existence and all human activities, including healing and medicine. This review examines the possibility that what we have learned from quantum mechanics may provide clues to better understand the operational principles of oriental medicine in an integrated way. Common to both is the assertion that Consciousness is at the foundation of the universe and the inner core of all human beings. This view goes beyond both science and medicine and has strong philosophical foundations in Western philosophy as well as monistic systems of the East.

A Detection Method of Ectocervical Cell Nuclei for Pap test Images, Based on Adaptive Thresholds and Local Derivatives

Julio Oscanoa,Marcelo Mena,Guillermo Kemper 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.2

Cervical cancer is one of the main causes of death by disease worldwide. In Peru, it holds the first place in frequency and represents 8% of deaths caused by sickness. To detect the disease in the early stages, one of the most used screening tests is the cervix Papanicolaou test. Currently, digital images are increasingly being used to improve Pap test efficiency. This work develops an algorithm based on adaptive thresholds, which will be used in Pap smear assisted quality control software. The first stage of the method is a pre-processing step, in which noise and background removal is done. Next, a block is segmented for each one of the points selected as not background, and a local threshold per block is calculated to search for cell nuclei. If a nucleus is detected, an artifact rejection follows, where only cell nuclei and inflammatory cells are left for the doctors to interpret. The method was validated with a set of 55 images containing 2317 cells. The algorithm successfully recognized 92.3% of the total nuclei in all images collected.

Embolization of an Exophytic Posterior Neck Mass Secondary to a Cutaneous Renal Cell Carcinoma Metastasis

Kramer Dallas E.,Kerolus Mena G.,Tan Lee A.,Patel Smita,Reddy Vijaya,Chen Michael 대한신경중재치료의학회 2020 Neurointervention Vol.15 No.3

Renal cell carcinoma (RCC) commonly metastasizes to the lung, liver, bones, and brain; however, cutaneous metastases remain rare with few reported cases. Since RCCs have the propensity to metastasize to highly vascular areas, the scalp and skin of the head and neck region are likely locations for cutaneous metastases. We report a rare case of a large, exophytic, cauliflower-like, hemorrhagic, metastatic mass of the posterior neck. This is the first reported case of a head and neck cutaneous RCC metastasis treated with endovascular embolization prior to surgical resection. Due to the increased vascularity of RCCs and risk of excessive hemorrhage during resection, adjunctive embolization of cutaneous head and neck metastasis may have a role. Essential characteristics to our treatment strategy are discussed with a review of pertinent literature.

The Magnesium-Rich Formula for Functional Constipation in Infants: a Randomized Comparator-Controlled Study

Marc A. Benninga,MENA Infant Constipation Study Group,Yvan Vandenplas 대한소아소화기영양학회 2019 Pediatric gastroenterology, hepatology & nutrition Vol.22 No.3

Purpose: To compare the effectiveness of the magnesium (Mg)-enriched formula vs. control formula in constipated infants. Methods: An open-label, interventional, and the comparator-controlled study was conducted to evaluate the effectiveness of the Mg-enriched formula in formula-fed infants ≤6 months old presenting with functional constipation according to modified Rome IV criteria. Infants were randomized 1:1 to intervention or control formula for 30 days. Parents recorded stool consistency (hard, normal, or watery) and frequency on days 1–7 and 23–29. Physicians recorded patient baseline characteristics and performed the clinical examination at the time of three patient visits (baseline, day 8, and 30). Results: Of the 286 recruited infants, 143 received the Mg-rich formula and 142 received the control formula. After 7 days, significantly more infants had stools with normal consistency with the Mg-rich formula compared to the infants fed with the control formula (81.8% vs. 41.1%; p <0.001). The number of infants passing one or more stools per day was increased at day 7 in the Mg-rich formula group (86.7% vs. 68.2%; p <0.001). At days 7 and 29, >25% of infants responded completely to the Mg-rich formula compared to <5% of infants fed with the control formula ( p <0.001). Parents of infants in the Mg-rich formula group were very satisfied with the treatment (80.8% vs. 10.2%), with the majority willing to continue treatment after 30 days (97.9% vs. 52.6%; p <0.001). Conclusion: The Mg-rich formula significantly improved stool consistency and frequency compared to the control formula in constipated infants.

The influence of the negative wake on the deformation and breakup of viscoelastic droplets

Fernando Carril-Naranjo,Baltsar Mena,Didier Samayoa,Antonio Guerrero,Bernardo Figueroa-Espinoza 한국유변학회 2021 Korea-Australia rheology journal Vol.33 No.3

Experiments were performed using visual and PIV techniques in order to study the appearance of a negative wake as well as its influence upon the deformation and breakup of droplets rising in viscoelastic fluids. In this report, Newtonian and viscoelastic drops were injected through different viscoelastic fluids; the deformation of the droplets was then followed and analyzed. In the case of Newtonian drops traveling through a viscoelastic fluid, a tail appears which later breaks into satellite droplets; a negative wake is present on the sides of the tail. The viscoelastic drops also exhibit a tail which is more resistant to rupture and the negative wake appears after the tail; additionally, a bump appears at the tip of the tail which enhances its elongation and determines the onset of breakup.

Hesham Mohamed Gharieb,Mo’mena Ahmad A Awad-Allah,Anas Adel Ahmed,Ihab Saad Othman 대한안과학회 2021 Korean Journal of Ophthalmology Vol.35 No.2

Purpose: To compare single-step transepithelial photorefractive keratectomy (TPRK) to conventional alcohol assisted epithelialremoval then photorefractive keratectomy (AAPRK) regarding pain, epithelial healing, visual acuity, corneal haze measuredsubjectively and objectively, higher order aberrations changes, contrast sensitivity and vector analysis of astigmatic correctionwith one year follow-up. Methods: A prospective double-blind randomized study of 29 subjects (58 eyes) who underwent myopic aberration-freelaser correction by smart pulse technology using Schwind Amaris 1050 Hz with 1-year follow-up. Right eye was randomlytreated by AAPRK or TPRK. Postoperative assessment was performed on day 1 and 3, at 1st week, and 1st, 3rd, 6th, and 12thmonths. Patients were assessed for pain, epithelial healing, visual acuity, corneal haze, astigmatic correction, higher order aberrationsand contrast sensitivity. Results: Epithelial healing was complete by the 3rd day in 62.1% of AAPRK eyes and in 89.7% of TPRK eyes. First day postoperativepain was higher in TPRK group (p = 0.0134). The decimal uncorrected visual acuity at 12 months was 1.47 ± 0.39 and1.57 ± 0.38 in the AAPRK and TPRK groups respectively (p = 0.3719). Post-photorefractive keratectomy haze reached a finallevel of 0.04 ± 0.14 and 0.02 ± 0.1 in AAPRK and TPRK groups respectively (p = 0.5607). Contrast sensitivity was comparable inlow and high frequency cycles per degree. Vector analysis of astigmatic correction showed correction index at one year of 0.99and 1.05 for AAPRK and TPRK groups respectively. Conclusions: Alcohol assisted and transepithelial photorefractive keratectomy have comparable results regarding safety andefficacy.
