In vitro and in vivo evaluation of two combined β-lactamase inhibitors against carbapenem-resistant Acinetobacter baumannii.

The objective of this study was to evaluate the in vitro and in vivo efficacy of clavulanic acid (C/A) in combination with tazobactam against clinical strains of carbapenem-resistant Acinetobacter baumannii. The MIC of 24 clinical strains of A. baumannii was determined, and a checkerboard assay and time-kill curve analysis were performed in selected strains to determine the synergy between C/A and tazobactam.

Reveals an Additional Level of Flowering Regulation in the Shoot Apical Meristem in Response to Light and Increased Temperature in Arabidopsis.

Light and photoperiod are environmental signals that regulate flowering transition. In plants like , this regulation relies on CONSTANS, a transcription factor that is negatively posttranslational regulated by phytochrome B during the morning, while it is stabilized by PHYA and cryptochromes 1/2 at the end of daylight hours. CO induces the expression of , whose protein travels from the leaves to the apical meristem, where it binds to FD to regulate some flowering genes.

Randomized phase II clinical trial of ruxolitinib plus simvastatin in COVID19 clinical outcome and cytokine evolution.

Background: Managing the inflammatory response to SARS-Cov-2 could prevent respiratory insufficiency. Cytokine profiles could identify cases at risk of severe disease.

Methods: We designed a randomized phase II clinical trial to determine whether the combination of ruxolitinib (5 mg twice a day for 7 days followed by 10 mg BID for 7 days) plus simvastatin (40 mg once a day for 14 days), could reduce the incidence of respiratory insufficiency in COVID-19.

In Vitro and In Vivo Virulence Study of Isolated from the Andalusian Outbreak in 2019.

In 2019, the biggest listeriosis outbreak by (Lm) in the South of Spain was reported, resulting in the death of three patients from 207 confirmed cases. One strain, belonging to clonal complex 388 (Lm CC388), has been isolated. We aimed to determine the Lm CC388 virulence in comparison with other highly virulent clones such as Lm CC1 and Lm CC4, in vitro and in vivo.

A surge in obsidian exploitation more than 1.2 million years ago at Simbiro III (Melka Kunture, Upper Awash, Ethiopia).

Pleistocene archaeology records the changing behaviour and capacities of early hominins. These behavioural changes, for example, to stone tools, are commonly linked to environmental constraints. It has been argued that, in earlier times, multiple activities of everyday life were all uniformly conducted at the same spot.

Interactions of Comorbidity and Five Simple Environmental Unhealthy Habits Concerning Physical and Mental Quality of Life in the Clinical Setting.

The objective of this study was to examine the interactions between comorbidity and five lifestyle single habits concerning different subscales of quality of life (QoL). For the study, 302 patients were consecutively recruited at the internal medicine department of a tertiary teaching hospital. Lifestyle habits, comorbidities and QoL were recorded according to validated questionnaires.

Social Science Pedagogy as a Way of Integrating Sustainable Education and Global Citizenship into the Initial Training of Pre-Primary Teachers.

The main objective of this research was to demonstrate the integration of international and national strategies in education for sustainable development and global citizenship into initial teacher training. The researchers analyzed the outcomes of a feminist teaching strategy based on family trees, focusing on the usefulness of social science pedagogy in developing critical thinking among pupils. They also attempted to enhance teachers' digital literacy and make progress in reflecting on its functioning and use.

Corrigendum: CXCL17 Is a Specific Diagnostic Biomarker for Severe Pandemic Influenza A(H1N1) That Predicts Poor Clinical Outcome.

Clinical and Immunological Factors That Distinguish COVID-19 From Pandemic Influenza A(H1N1).

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), is a global health threat with the potential to cause severe disease manifestations in the lungs. Although COVID-19 has been extensively characterized clinically, the factors distinguishing SARS-CoV-2 from other respiratory viruses are unknown. Here, we compared the clinical, histopathological, and immunological characteristics of patients with COVID-19 and pandemic influenza A(H1N1).

CXCL17 Is a Specific Diagnostic Biomarker for Severe Pandemic Influenza A(H1N1) That Predicts Poor Clinical Outcome.

The C-X-C motif chemokine ligand 17 (CXCL17) is chemotactic for myeloid cells, exhibits bactericidal activity, and exerts anti-viral functions. This chemokine is constitutively expressed in the respiratory tract, suggesting a role in lung defenses. However, little is known about the participation of CXCL17 against relevant respiratory pathogens in humans.

Cross-sectional evaluation of the interaction between activity relative-time expenditure and comorbidity concerning physical quality of life.

Quality of life (QoL) is a matter of concern in both healthy and diseased individuals. Lifestyle factors such as physical activity and sleep have a direct impact on QoL. In this context, interactions between activity time expenditure and QoL might be different in comorbid and non comorbid patients.

Munc18-2, but not Munc18-1 or Munc18-3, controls compound and single-vesicle-regulated exocytosis in mast cells.

Mast cells (MCs) play pivotal roles in many inflammatory conditions including infections, anaphylaxis, and asthma. MCs store immunoregulatory compounds in their large cytoplasmic granules and, upon stimulation, secrete them via regulated exocytosis. Exocytosis in many cells requires the participation of Munc18 proteins (also known as syntaxin-binding proteins), and we found that mature MCs express all three mammalian isoforms: Munc18-1, -2, and -3.

Clinical outcomes of trochanteric syndrome endoscopically treated.

Background: Greater trochanteric pain syndrome (GTPS) is clinically defined as greater trochanter pain with mechanical characteristics. Most cases of GTPS are resolved with conservative treatment. Surgical techniques are reserved for those who had unsatisfactory results with conservative treatment.

Evaluation of the presence and severity of menopausal symptoms among postmenopausal women screened for the metabolic syndrome.

Background: The prevalence of the metabolic syndrome (METS) increases after the menopause. Reports indicate that the METS and its components, especially obesity, enhance the intensity of menopausal symptoms.

Objective: Assess the frequency and severity of menopausal symptoms in postmenopausal women.

The metabolic syndrome and its components in postmenopausal women.

Background: Prevalence of the metabolic syndrome (METS) increases significantly after the menopause.

Objective: To assess the prevalence of the METS and its components in postmenopausal women. Factors relating to each of the composing items of the METS were also analyzed.

Assessment of insomnia and related risk factors in postmenopausal women screened for the metabolic syndrome.

Background: Sleep disturbances are common during female mid-life. Nevertheless, there is limited available information linking sleep characteristics to the menopause and the metabolic syndrome (METS).

Objective: To assess insomnia prevalence and related risk factors in postmenopausal women screened for the METS.
