Carbon Inks-Based Screen-Printed Electrodes for Qualitative Analysis of Amino Acids.

Due to the great significance of amino acids, a substantial number of research studies has been directed toward the development of effective and reliable platforms for their evaluation, detection, and identification. In order to support these studies, a new electrochemical platform based on PANI/ZnO nanowires' modified carbon inks screen-printed electrodes was developed for qualitative analysis of electroactive amino acids, with emphasis on tyrosine (Tyr) and tryptophan (Trp). A comparative investigation of the carbon ink before and after modification with the PANI/ZnO was performed by scanning electron microscopy and by Raman spectroscopy, confirming the presence of PANI and ZnO nanowires.

[Evaluation of COVID-19 emergency and state of alarm impact on Neonatal Screening Programs in Madrid: endocrine and metabolic disorders program and hearing program review.].

Objective: Under the declaration of the state of alarm (SA) in efforts to control COVID-19, normal development of health programs was threatened. The aim of the study was the evaluation of COVID 19 emergency and SA approval impact on neonatal Endocrine and Metabolic Disorders Program (EMDP) and Neonatal Hearing Program (HP) in Madrid.

Methods: Qualitative and quantitative descriptive study was conducted.

Absence of α-calcitonin gene-related peptide modulates bone remodeling properties of murine osteoblasts and osteoclasts in an age-dependent way.

Mice with an overall deletion of the sensory neuropeptide α-calcitonin gene-related peptide (α-CGRP) develop an age-dependent osteopenic bone phenotype. Underlying molecular mechanisms of how αCGRP affects bone cell metabolism are not well understood. This study aims to characterize differences in metabolic parameters of osteoblast-like cells (OB) and differentiated bone marrow-derived macrophages (BMM)/osteoclast (OC) cultures isolated from 3 month (3 m) and 9 month old (9 m) α-CGRP-deficient mice (-/-) and age-matched WT controls.

Corticotropin-releasing factor 1 receptor mediates the activity of the reward system evoked by morphine-induced conditioned place preference.

Different neurotransmitter systems are involved in behavioural and molecular responses to morphine. The brain stress system is activated by acute administration of drugs of abuse, being CRF the main neuropeptide of this circuitry. In this study we have studied the role of CRF1R in the rewarding effects of morphine using the CPP paradigm.

Hypothalamic orexin--a neurons are involved in the response of the brain stress system to morphine withdrawal.

Both the hypothalamus-pituitary-adrenal (HPA) axis and the extrahypothalamic brain stress system are key elements of the neural circuitry that regulates the negative states during abstinence from chronic drug exposure. Orexins have recently been hypothesized to modulate the extended amygdala and to contribute to the negative emotional state associated with dependence. This study examined the impact of chronic morphine and withdrawal on the lateral hypothalamic (LH) orexin A (OXA) gene expression and activity as well as OXA involvement in the brain stress response to morphine abstinence.

[Detection of a rotavirus G9P[8] outbreak causing gastroenteritis in a geriatric nursing home].

Introduction: The aim of this study was to describe an outbreak of gastroenteritis due to rotavirus in a geriatric nursing home.

Method: Stool samples from 8 patients were studied. Antigen detection was carried out by ELISA, and molecular typing was performed by RT-PCR.

Specific aspects of erectile dysfunction in psychiatry.

The participation of the psychiatrist in the management of erectile dysfunction (ED) is focused on three types of patients based on the origin of the dysfunction: (1) patients with functional or psychogenic ED, (2) patients with mixed, organic psychogenic ED, and (3) patients with ED and active psychopathology. The second group is influenced by three psychological factors: perpetuating factors, aggravating factors, and accompanying factors. The main psychopathological disorders that interfere directly with the erectile mechanism are depressive disorders (18-35%), anxiety disorders (37%), obsessive-compulsive disorder, psychotic disorders (46-47%), and the antipsychotic medications used to treat these disorders.
