Percutaneous versus Transcutaneous Electrical Stimulation of the Posterior Tibial Nerve in Idiopathic Overactive Bladder Syndrome with Urinary Incontinence in Adults: A Systematic Review

Background: Percutaneous electrical stimulation and transcutaneous electrical stimulation (PTNS and TTNS) of the posterior tibial nerve are internationally recognized treatment methods that offer advantages in terms of treating patients with overactive bladder (OAB) who present with urinary incontinence (UI). This article aims to analyze the scientific evidence for the treatment of OAB with UI in adults using PTNS versus TTNS procedures in the posterior tibial nerve. Methods: A systematic review was conducted, between February and May 2021 in the Web of Science and Scopus databases, in accordance with the PRISMA recommendations. Results: The research identified 259 studies, 130 of which were selected and analyzed, with only 19 used according to the inclusion requirements established. The greatest effectiveness, in reducing UI and in other parameters of daily voiding and quality of life, was obtained by combining both techniques with other treatments, pharmacological treatments, or exercise. Conclusions: TTNS has advantages over PTNS as it is more comfortable for the patient even though there is equality of both therapies in the outcome variables. More research studies are necessary in order to obtain clear scientific evidenc

Eating Disorders as New Forms of Addiction

Eating disorders (ED) seem to share many characteristics with substance-related disorders (SRD). As very often the two conditions run together, it has been proposed that eating dysfunctions could be understood as behavioral forms of addiction. This has lead to the concept of “food addiction,” a proposed new form of addiction. This chapter reviews recent research focusing on the relationship between ED and SRD. Three specific areas are addressed: (a) animal models that suggest the association between substance dependence and compulsive overeating; (b) epidemiological studies that confirm the comorbidity between ED and SRD; and (c) neuroimaging studies that reveal the existence of modifications in the reward circuits following binge eating and other eating dysfunctions. The data from the different studies can be integrated into a model based on the consideration of “food addiction” as a specific form of behavioral addiction that could be applied at least to a group of patients suffering from eating disorders

Analysis and comparison of monofocal, extended depth of focus and trifocal intraocular lens profiles

To test the feasibility of using profilometers to extract information about IOL surfaces design. A standard monofocal IOL (Tecnis 1), a monofocal IOL that provided some depth of focus (Eyhance), an extended depth of focus IOL based on refractive optics (Mini Well) and a trifocal IOL based on diffractive optics were used in this study (Tecnis Synergy). The surface topography of the IOLs was measured by using a multimode optical profilometer. Posterior surface of Tecnis 1 IOL was spherical and the anterior surface aspherical. In the Eyhance IOL, posterior surface was spherical and anterior surface did not fit to any of our reference surfaces, indicating a higher order aspheric surface design. In the Mini Well Ready IOL, a best-fit sphere surface was obtained for the second surface and a high order aspherical surface design was deduced for the first surface. The anterior surface of the Synergy IOL was aspherical and the base curve of the diffractive structure fitted very well to a spherical surface. To consider an aspheric surface as possible best-fit surface provided more information than if only best-fit spherical surface was considered. The high order aspheric surface designs employed in the IOLs studied presented differences, regarding best-fit asphere surface, higher than 1 micron. These differences were correlated with the generation of spherical aberration complex profiles (with Zernike terms higher than 4th order) and with the production of distinct amounts of depth of focus. This method was also useful to deduce the base curve of diffractive surfaces.This work was supported by the “Generalitat Valenciana” of Spain (project AICO/2021/130)

ALC1/eIF4A1-mediated regulation of CtIP mRNA stability controls DNA end resection

During repair of DNA double-strand breaks, resection of DNA ends influences how these lesions will be repaired. If resection is activated, the break will be channeled through homologous recombination; if not, it will be simply ligated using the non-homologous end-joining machinery. Regulation of resection relies greatly on modulating CtIP, which can be done by modifying: i) its interaction partners, ii) its post-translational modifications, or iii) its cellular levels, by regulating transcription, splicing and/or protein stability/degradation. Here, we have analyzed the role of ALC1, a chromatin remodeler previously described as an integral part of the DNA damage response, in resection. Strikingly, we found that ALC1 affects resection independently of chromatin remodeling activity or its ability to bind damaged chromatin. In fact, it cooperates with the RNA-helicase eIF4A1 to help stabilize the most abundant splicing form of CtIP mRNA. This function relies on the presence of a specific RNA sequence in the 5' UTR of CtIP. Therefore, we describe an additional layer of regulation of CtIP-at the level of mRNA stability through ALC1 and eIF4A1

Synthesis of 3-alkoxypropan-1,2-diols from glycidol: experimental and theoretical studies for the optimization of the synthesis of glycerol derived solvents

A straightforward synthetic methodology has been derived for the synthesis of glycerol monoethers from glycidol and alcohols. Several homogeneous and heterogeneous basic catalysts have been tested, the best results being obtained with readily available and inexpensive alkaline metal hydroxides. In the best case, good yield of the desired monoether is obtained under smooth reaction conditions, always with total conversion of glycidol. The selectivity of the reactions mainly depends on the alcohol used, due to the concurrence of undesired side reactions. A mechanistic study carried out through computational DFT calculations, in which solvent effects are taken into account, also complemented the experiments, has allowed to identify the main reaction paths taking place under reaction conditions, giving insights into the main causes affecting the reaction selectivity and also into how it could be improved

Using Flipped classroom at University to improve the chemistry learning.

The main objective of this paper was to improve the learning of Chemistry subject using Flipped classroom, because it makes class time more engaging. The lecture portion of General Chemistry courses in engineers degrees have been pushed outside the classroom using pre recording technology and steaming delivery of content, to make classes more interactive and participative. The Flipped classroom model has become one of the main topics in the higher education space in recent years thanks to improvements in technology. This year, the Flipped classroom model with the chemistry students at Malaga State University has been begun experimenting with. Statistical significance of the data has shown, and proved with, that implementing the Flipped classroom model could not only benefit professors, but it could also help us adapt the classes to the various learning styles that exist among the students. The study shows the results of surveys about student attitudes towards aspects of flipping the classroom.I Plan Propio Integral de Docencia, Universidad de Málaga.

Implicaciones funcionales de los linfocitos B en el desarrollo de la artritis reumatoide

ResumenLos linfocitos B tienen un papel importante en la regulación del sistema inmune, pues además de producir anticuerpos, son células presentadoras de antígenos que interactúan con otras células mo- nonucleares y contribuyen directameníe en las vías inflamatorias. Existe evidencia acerca de una disrupción en la regulación de estos procesos en la patogénesis de las enfermedades autoinmunes, tales como la artritis reumatoide (AR). Esta enfermedad se caracíeriza por una inflamación crónica de las articulaciones afectadas en las que es característico el desarrollo de centrosgerminales ectópicos en la membrana sinovial. Este microambiente facilita la diferenciación y activación de las células B, las cuales, al transformarse en células plasmáticas, secretan directamente en la membrana sinovial anticuerpos de alta afinidad. en consecuencia. la formación de complejos inmunes con la posterior activación de la cascada del complemento y el estímulo de macrófagos, contribuyen en la destrucción de la articulación. Las células B también tienen un papel relevante en la activación de las células T sinoviales y en la inducción de la síntesis de citoquinas.cinalmeníe, la eficacia terapéutica obtenida con la depleción de linfocitos B por medio del uso de anticuerpos monoclonales contra CD20, enfatiza su importancia en la patogénesis de la AR.[Páez M-C, Gómez LM, Anaya J-M.
