The security and privacy provided by Visible Light Communication (VLC) technologies is an area that has been slightly addressed due to the misconception that, since light does not go through solid objects like walls, VLC-based communications cannot be eavesdropped on by outside observers. As an upcoming technology, VLC is expected to be used in multiple environments were, due to radio frequency RF overuse or limitations, RF solutions cannot or should not be employed. In this work, we study the eavesdropping characteristics of a VLC-based communication...

Leptin is now considered an important signalling molecule of the reproductive system, as it regulates the production of gonadotrophins, the blastocyst formation and implantation, the normal placentation, as well as the foeto-placental communication. Leptin is a peptide hormone secreted mainly by adipose tissue, and the placenta is the second leptin-producing tissue in humans. Placental leptin is an important cytokine which regulates placental functions in an autocrine or paracrine manner. Leptin seems to play a crucial role during the first stages of pregnancy as it modulates critical processes such as proliferation, protein synthesis, invasion and apoptosis in placental cells...

BACKGROUND AND AIMS: Krüppel Like Factors (KLF) refers to a family of seventeen members of transcription factors. Involved in several cellular processes. As other cancer types, Cervical Cancer (CC) presents molecular deregulations in transcription factors, but especially Human Papilloma Virus (HPV) sequences. Here in this work we analyzed the mRNA expression of all KLF family members in CC-derived cell lines and CC tissues. METHODS: The cell lines used were HeLa, INBL, RoVa, C4-I, Ms751, ViPa, CaLo, SiHa, CaSki, C33a and ViBo and the non-tumorigenic HaCaT...

We report here the complete genome sequence of Rhizobium sp. strain ACO-34A, isolated from Agave americana L. rhizosphere. No common nod genes were found, but there were nif genes for nitrogen fixing. A low average nucleotide identity to reported species supports its designation as a novel Rhizobium species that has a complete ribosomal operon in a plasmid.

INTRODUCTION AND OBJECTIVES: X-linked cardiac valvular dysplasia is a rare form of male-specific congenital heart defect mainly characterized by myxomatous degeneration of the atrioventricular valves with variable hemodynamic consequences. It is caused by genetic defects in FLNA-encoded filamin A, a widely expressed actin-binding protein that regulates cytoskeleton organization. Filamin A loss of function has also been associated with often concurring neurologic and connective tissue manifestations, with mutations in the first half of the Rod 1 domain apparently expressing the full cardiac phenotype...

Agriculture first reached the Iberian Peninsula around 5700 BCE. However, little is known about the genetic structure and changes of prehistoric populations in different geographic areas of Iberia. In our study, we focus on the maternal genetic makeup of the Neolithic (~ 5500-3000 BCE), Chalcolithic (~ 3000-2200 BCE) and Early Bronze Age (~ 2200-1500 BCE). We report ancient mitochondrial DNA results of 213 individuals (151 HVS-I sequences) from the northeast, central, southeast and southwest regions and thus on the largest archaeogenetic dataset from the Peninsula to date...

BACKGROUND: The influence of dietary habits on the development of gastric adenocarcinoma is not clear. The objective of the present study was to explore the association of three previously identified dietary patterns with gastric adenocarcinoma by sex, age, cancer site, and morphology. METHODS: MCC-Spain is a multicase-control study that included 295 incident cases of gastric adenocarcinoma and 3040 controls. The association of the Western, Prudent, and Mediterranean dietary patterns-derived in another Spanish case-control study-with gastric adenocarcinoma was assessed using multivariable logistic regression models with random province-specific intercepts and considering a possible interaction with sex and age...

Photocatalytic bond activations are generally limited by the photon energy and the efficiency of energy and electron transfer processes. Direct two-photon processes provide sufficient energy but the ultra-short lifetimes of the excited states prohibit chemical reactions. The commercial dye 9,10-dicyanoanthracene enabled photocatalytic aromatic substitutions of non-activated aryl halides. This reaction operates under VIS irradiation via sequential photonic, electronic, and photonic activation of the simple organic dye...

The pathogenic infectious pancreatic necrosis virus (IPNV) causes high economic losses in fish farming. This virus can modulate several cellular processes during infection, but little is known about the infection mechanism. To investigate gene activation in response to IPNV, CHSE/F and SHK-1 cell line were infected with a cytopathic Sp field isolate of IPNV, and the expression profiles of proinflammatory, antiviral cytokine, and extracellular matrix markers were analyzed. IPNV induced the production of perlecan, fibulin-1, matrix metalloproteinase-2, 14-3-3β, interleukin-1β, Mx1, and interferon regulatory factors-1, -3, and -9...

Auxin and polar auxin transport have been implicated in controlling zygotic embryo development, but less is known about their role in the development of somatic embryos. The aim of this study was to determine if indole-3-acetic acid (IAA) and the PIN1 transporter participate in the induction of somatic embryogenesis (SE) and the development of somatic embryos. The results show that IAA levels gradually increase during pre-treatment and accumulate in the chloroplast. During pre-treatment and the globular stage of SE in C...

This study assessed 24 adult patients, suffering from severe chronic unilateral pain diagnosed as temporomandibular joint (TMJ) disorder (TMD). The full dentate patients had normal occlusion and had never received an occlusal therapy, i.e., were with natural dental evolution/maturation. The following functional and dynamic factors were assessed: (1) chewing function; (2) TMJ remodeling or the condylar path (CP); and (3) lateral jaw motion or lateral guidance (LG). CPs were assessed using conventional axiography, and LG was assessed by K7 jaw tracking...

BACKGROUND: There is a lack of clinical information regarding the usefulness of plasma Epstein-Barr virus (EBV) DNA load kinetics analyses in the management of EBV infections in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients. Namely, it remains unknown whether this type of analysis can help physicians to anticipate the development of high-level EBV DNAemia episodes requiring rituximab treatment or predict the risk of recurrent EBV DNAemia or post-transplant lymphoproliferative disorders (PTLDs)...

The involvement of GALNT12 in colorectal carcinogenesis has been demonstrated but it is not clear to what extent it is implicated in familial CRC susceptibility. Partially inactivating variant, NM_024642.4:c.907G>A, p.(D303N), has been previously detected in familial CRC and proposed as the causative risk allele. Since phenotypes of the described carrier families showed not only CRC but also a polyp history, we hypothesized that GALNT12 could be involved in adenoma predisposition and consequently, in hereditary polyposis CRC syndromes...

Sarcopenia has been evaluated as a separate condition in cancer patients and as an important indicator of adverse outcomes. Muscle mass and phase angle are usually quantified by bioelectrical impedance analysis, due to its lower cost, and availability. The aim of this study was to assess the impact of sarcopenia, phase angle, and other characteristics on overall survival (OS) in palliative cancer patients at the National Cancer Institute of Mexico. We enrolled 628 patients (female, 59%). The most frequent disease was gastric cancer (39...

INTRODUCTION: The use of second-generation antipsychotics (SGA) has been associated with metabolic changes. However, there are differences in the metabolic profile between SGAs. We have previously observed that ziprasidone had a more benign early metabolic profile compared to aripiprazole and quetiapine. However, a long-term follow-up is preferred to detect clinically relevant impairment in metabolic parameters. We aimed to compare the effect of aripiprazole, ziprasidone, and quetiapine on metabolic measures in first-episode non-affective psychosis patients after 1 year of treatment...

BACKGROUND: The weaning pig is used as an experimental model to assess the impact of diet on intestinal health. Blood parameters (BP) are considered a useful tool in humans, but there is very scarce information of such indicators in the weaning pig. The objective of the present study is to evaluate the use of different BP as indicators in an experimental model of salmonellosis. METHODOLOGY: Seventy-two 28-day-old piglets were divided into four groups in a 2x2 factorial arrangement, with animals receiving or not a probiotic combination based on B...

Background: Post-traumatic stress disorder (PTSD) can occur in both adults and children/adolescents. Untreated PTSD can lead to negative long-term mental health conditions such as depression, anxiety, low self-concept, disruptive behaviors, and/or substance use disorders. To prevent these adverse effects, treatment of PTSD is essential, especially in young population due to their greater vulnerability. The principal aim of this meta-analysis was to examine the efficacy of eye movement desensitization and reprocessing (EMDR) therapy for PTSD symptoms in children and adolescents...
