AIMTo evaluate the intra-operator repeatability in healthy subjects using the WAM-5500 auto-kerato/refractometer and the iTrace aberrometer, to compare the refractive values and the subjective refraction obtained with both devices and to determine which of these three spherocylindrical corrections allows the subject to achieve the best visual ***-two non-presbyopic healthy eyes of 42 subjects were enrolled in this prospective study. Refractive values were compared, evaluating the repeatability, the relationship between the methods and the best visual comfort ***, cylinder and axis results showed good intraclass correlation coefficients (ICC); the highest ICC was obtained using the spherical refraction with the autorefractometer and the aberrometer, achieving levels of 0.999 and 0.998, respectively. The power vector (PV) was calculated for each refraction method, and the results indicated that there were no statistically significant differences between them (P>0.05). Direct comparison of PV measurements using the three methods showed that aberrometer refraction gave the highest values, followed by the subjective values; the autorefractometer gave the lowest values. The subjective method correction was most frequently chosen as the first selection. Equal values were found for the autorefractometer and the aberrometer as the second *** iTrace aberrometer and the WAM-5500 auto-kerato/refractometer showed high levels of repeatability in healthy eyes. Refractive corrections with the aberrometer, the autorefractometer and subjective methods presented similar results, but spherocylindrical subjective correction was the most frequently selected option. These technologies can be used as complements in refractive evaluation, but they should not replace subjective refraction.

Laparoscopic approach in gastrointestinal emergencies

引用

World Journal of Gastroenterology 2016年第9期22卷 2701-2710页

作者： Rosa M Jimenez Rodriguez Juan José segura-Sampedro Mercedes Flores-Cortés francisco López-Bernal Cristobalina Martín Verónica Pino Diaz Felipe Pareja Ciuro Javier Padillo Ruiz Department of Surgery Hospital Universitario Virgen del Rocio 41013 Sevilla Spain Hospital Universitario Son Espases 07010 Palma de Mallorca Spain

This review focuses on the laparoscopic approach to gastrointestinal emergencies and its more recent indications. Laparoscopic surgery has a specific place in elective procedures, but that does not apply in emergency situations. In specific emergencies, there is a huge range of indications and different techniques to apply, and not all of them are equally settle. We consider that the most controversial points in minimally invasive procedures are indications in emergency situations due to technical difficulties. Some pathologies, such as oesophageal emergencies, obstruction due to colon cancer, abdominal hernias or incarcerated postsurgical hernias, are nearly always resolved by conventional surgery, that is, an open approach due to limited intraabdominal cavity space or due to the vulnerability of the bowel. These technical problems have been solved in many diseases, such as for perforated peptic ulcer or acute appendectomy for which a laparoscopic approach has become a wellknown and globally supported procedure. On the other hand, endoscopic procedures have acquired further indications, relegating surgical solutions to a second place; this happens in cholangitis or pancreatic abscess drainage. This endoluminal approach avoids the need for laparoscopic development in these diseases. Nevertheless, new instruments and new technologies could extend the laparoscopic approach to a broader array of potentials procedures. There remains, however, a long way to go.

The quest for selective Cs^(+) transport in plants

Nuclear accidents have led to the release to the environment of radioactive isotopes,mainly radioactive cesium(Cs^(+)),contaminating large areas of soil for very long periods of time(Burger and Lichtscheidl,2018).These contaminated soils contain^(134)Cs^(+)and^(137)Cs^(+)radioisotopes that are readily accumulated into plants and that,through the food chain,are transferred to animals and humans,causing important health problems(Burger and Lichtscheidl,2018).

The Social Determinants of Health in Relation to Sexually Transmitted Infections in Maricopa County Arizona

Advances in Infectious Diseases 2022年第2期12卷 328-336页

作者： Benjamin Picciano Andrea Vizcaino Rosa Angelica Hernandez francisco Javier Vizcaino Carla segura Coutino Alonso Trevino IV Javier Paz International University of the Health Sciences Basseterre Saint Kitts and Nevis School of Medicine Universidad Autónoma de Guadalajara Guadalajara Mexico

Based on the information that was collected on the County Health Rankings website [1], one of the top health concerns for Maricopa County was sexually transmitted infections or STIs. A big concern with STIs is this is not a common subject explored in educational settings or addressed socially. There are many organizations, including the CDC, that have access to materials, there is limited distribution of the educational content. Therefore, the public is not well informed and lacks the information to make educated decisions. The areas with insufficiencies are knowledge of the disease processes, prevention, and treatment.

The Arabidopsis thaliana HAK5 K＋ Transporter Is Required for Plant Growth and K＋ Acquisition from Low K＋ Solutions under Saline Conditions

引用

Molecular Plant 2010年第2期3卷 326-333页

作者： Manuel Nieves-Cordones Fernando Aleman Vicente Martinez francisco Rubio Departamento de Nutricion Vegetal Centro de Edafologia y Biologia Aplicada del Segura CSlC Campus de Espinardo 30100 Murcia Spain

K＋ uptake in the high-affinity range of concentrations and its components have been widely studied. In Arabidposis thaliana, the AtHAK5 transporter and the AtAKT1 channel have been shown to be the main transport proteins involved in this process. Here, we study the role of these two systems under two important stress conditions： low K＋ supply or the presence of salinity. T-DNA insertion lines disrupting AtHAK5 and A tAKT1 are employed for long-term experi- ments that allow physiological characterization of the mutant lines. We found that AtHAK5 is required for K＋ absorption necessary to sustain plant growth at low K＋ in the absence as well as in the presence of salinity. Salinity greatly reduced AtHAK5 transcript levels and promoted AtAKTl-mediated K＋ efflux, resulting in an important impairment of K＋ nutrition. Although having a limited capacity, AtHAK5 plays a major role for K＋ acquisition from low K＋ concentrations in the presence of salinity.
