Finally, those who played card games (e.g. Kings) while prepartying also consumed more preparty drinks than those who do not typically play card games. Implications for prevention and intervention as well as future research directions are briefly discussed.Public support to firm-level investments in innovation is one of the main mechanisms through which the European Union promotes socioeconomic convergence among regions and the creation of quality jobs is considered a necessary condition for the convergence of disadvantaged regional economies. This paper exploits the availability of natural experiment conditions and linked employer-employee microdata in Portugal to offer empirical evidence on the impact on relevant job-quality outcomes of a large EU-cohesion-policy program to support SMEs' innovation investments. The analysis is implemented by means of stratification/coarsened exact matching model, combined with a difference in difference scheme, suitable to the specific impact identification conditions. Our results indicate that the policy intervention in Portugal had a positive impact on job-quality outcomes, with each supported firm generating an average of 4.9 additional standard-working-time jobs, +2.9 skilled jobs, and +2.0 permanent-contract jobs, compared to a counterfactual scenario of no public support. These impacts were at a cost of about 16,100€, 27,100€ and 39,400€ in public subsidies per additional job, respectively. We also estimate that the program impact was responsible for a 2.20€ (+17.8%) increase of the per-hour remuneration. These findings are robust to sensitivity analysis, in terms of alternative matching procedures and comparison groups, and they highlight the fact that increasing job-quality is a policy goal that can be pursued, at a reasonable cost, also by means of cohesion-policy support to innovation aimed at enhancing the competitiveness of SMEs.JEL classificationO1; R5; C23.Cerebral small vessel disease (cSVD) is a major cause of stroke and dementia. This review summarizes recent developments in advanced neuroimaging of cSVD with a focus on clinical and research applications. In the first section, we highlight how advanced structural imaging techniques, including diffusion magnetic resonance imaging (MRI), enable improved detection of tissue damage, including characterization of tissue appearing normal on conventional MRI. These techniques enable progression to be monitored and may be useful as surrogate endpoint in clinical trials. Quantitative MRI, including iron and myelin imaging, provides insights into tissue composition on the molecular level. In the second section, we cover how advanced MRI techniques can demonstrate functional or dynamic abnormalities of the blood vessels, which could be targeted in mechanistic research and early-stage intervention trials. Such techniques include the use of dynamic contrast enhanced MRI to measure blood-brain barrier permeability, and MRI methods to assess cerebrovascular reactivity. In the third section, we discuss how the increased spatial resolution provided by ultrahigh field MRI at 7 T allows imaging of perforating arteries, and flow velocity and pulsatility within them. The advanced MRI techniques we describe are providing novel pathophysiological insights in cSVD and allow improved quantification of disease burden and progression. They have application in clinical trials, both in assessing novel therapeutic mechanisms, and as a sensitive endpoint to assess efficacy of interventions on parenchymal tissue damage. We also discuss challenges of these advanced techniques and suggest future directions for research.Antigen-specific immune tolerance, which possesses great potential in preventing or curing type 1 diabetes mellitus (T1DM), can be induced by oral vaccination with T1DM-related autoantigens. However, direct administration of autoantigens via oral route exhibits a low tolerance-inducing effect as a result of the digestion of protein antigens in the gastrointestinal tract (GIT) and therefore, a large dosage of autoantigens may be needed. In this study, bacterium-like particles (BLPs) made from food-grade lactic acid bacteria were used to deliver the intracellular domain of the insulinoma-associated protein 2 (IA-2ic). For this purpose, BLPs-IA-2ic vaccine in which IA-2ic bound to the surface of BLPs was constructed. BLPs enhanced the stability of the delivered IA-2ic based on the stability analysis in vitro. Oral administration of BLPs-IA-2ic significantly reduced T1DM incidence in NOD mice. The mice fed BLPs-IA-2ic exhibited a significant reduction in insulitis and preserved the ability to secrete insulin. Immunologic analysis showed that oral vaccination with BLPs-IA-2ic induced antigen-specific T cell tolerance. The results revealed that the successful induction of immune tolerance was dependent on the immune deviation (in favor of T helper 2 responses) and CD4+CD25+FoxP3+ regulatory T cells. Hence, oral vaccination with BLPs-IA-2ic shows potential for application in preventing T1DM.
1. To describe what exercises and intervention variables are used in resistance training interventions in randomised controlled trials for lower limb tendinopathy 2. To assess completeness of reporting as assessed by the Consensus on Exercise Reporting Template (CERT) and the Toigo and Boutellier framework. 3. To assess the implementation of scientific resistance training principles. 4. To assess therapeutic quality of exercise interventions with the i-CONTENT tool.
We searched MEDLINE, CINAHL, AMED, EMBase, SPORTDiscus, and the Cochrane library databases.
Systematic review of randomised controlled trials that reported using resistance exercises for lower limb tendinopathies.
We included 109 RCTs. Eccentric heel drops were the most common exercise (43 studies), followed by isotonic heel raises (21), and single leg eccentric decline squats (18). Reporting of exercise descriptor items from the Toigo and Boutellier framework ranged from 0-13, with an average score of 9/13, and only 7 studies achieved a frting for some tendinopathies and content items such as adherence was poor, limiting optimal translation to clinical practice.
In order to select a suitable rat model for studying polycystic ovary syndrome (PCOS).
Post-pubertal Sprague Dawley (SD) rats were allocated to four groups, abbreviated as the control 1 group, DHEA subcutaneous injection (DHEA) group, control 2 group, letrozole intragastric injection (letrozole) group. Body weight and the estrous cycle were monitored during the modeling. Serum stress hormones and reproductive hormones were evaluated by ELISA. The uterus and ovaries were weighed, ovarian follicle counts were calculated, and AR, LHR, FSHR, and AMH expression were assessed by immunohistochemistry.
In both model group subjected to the 30-day protocol of DHEA or letrozole, the mean body weights were significantly increased. Rats from both model group exhibited a significant increase of the mean length of the diestrous phase of the estrous cycle, the DHEA group had a longer diestrous phase. There was also a significant increase of serum T, E2, LH, insulin, and a significant decrease of AMH in both model group. There was a significant decrease of ovarian weight, P, and serum FSH, and a significant increase of uterus weight, serum LH/FSH in DHEA model group. There was no significant difference in serum P, FSH, and LH/FSH in letrozole model group. Both two model groups showed significantly higher AR, LHR, and AMH protein expression in rats' ovaries. FSHR protein expression in DHEA group was lower, and in letrozole model group was not different.
Compared with letrozole intragastric injection group, the pathological characteristics of DHEA subcutaneous injection group rats were closer to the characteristics of PCOS.
Compared with letrozole intragastric injection group, the pathological characteristics of DHEA subcutaneous injection group rats were closer to the characteristics of PCOS.
Stereotypes are oversimplified beliefs about groups of people. Social psychology concepts and theories describing ethnicity-related stereotypes are well reported in non-medical educational settings. In contrast, the full impact of stereotyping on medical students, and the extent to which they were represented in health professions education (HPE) is less well-described. Using the lens of social psychological theory, this review aimed to describe ethnicity-related stereotypes about medical students portrayed in HPE literature and the impacts of those stereotypes.
A critical narrative approach was undertaken. Social psychology concepts and theories were used as a framework through which to review the impacts of ethnicity-related stereotypes on medical students as described in HPE literature. A database search of Ovid MEDLINE, JSTOR, Project Muse, and PsychINFO was conducted to identify both theoretical and empirical articles relating to this topic in the HPE literature. Data was synthesised using thematic ase the impact of stereotyping and bias to create more inclusive learning environments.
Social psychology concepts and theories can be used to describe the experience and impact of ethnicity-related stereotypes in HPE. Educators can better support learners from minority ethnic groups by self-reflecting over assumptions about individuals from minority ethnic groups, as well as minimise the impact of stereotyping and bias to create more inclusive learning environments.Immune checkpoint blocking based on the PD-1/PD-L1 pathway has shown exciting results in various types of cancer. read more However, due to the off-target effect of PD-1/PD-L1 blocker, low tumour immunogenicity and tumour immunosuppressive microenvironment, a significant proportion of patients do not benefit from this treatment. Here, we constructed a novel multifunctional metal complex Fe/PEI-Tn by the coordination of polyethyleneimine (PEI) with Fe3+ and the modification of bifunctional peptides Tn containing the cell penetrating peptide (TAT) and nuclear localisation signal peptide (NLS), which was coated with hyaluronic acid (HA) to prolong the circulation time in vivo. Fe/PEI-Tn can condensate PD-L1 trap plasmid (pPD-L1 trap) and mediate PD-L1 trap protein expression in tumour tissues in situ, thus blocking the PD-1/PD-L1 pathway. Besides, Fe/PEI-Tn metal complex itself can act as an immune adjuvant to activate macrophages, reverse the phenotype of pro-tumour M2-type macrophages, and promote anti-tumour immunity. Meanwhile, Fe/PEI-Tn treatment can induce damage in tumour cells and release tumour-specific antigens into tumour microenvironment, thus stimulating anti-tumour immune response. Studies showed that HA/Fe/PEI-Tn/pPD-L1 trap complexes could promote the immune activation of tumour tissues and effectively delay tumour growth. This strategy provides a new direction for tumour combination therapy based on PD-1/PD-L1 blockade.To prepare ecdysterone (ES)/hydroxypropyl-β-cyclodextrin (HP-β-CD) inclusion complex, thus improving the water solubility and bioavailability of ES. Phase-solubility study was performed to study the mass ratio of ES and HP-β-CD. Then, the ES/HP-β-CD inclusion complex was prepared by the solvent evaporation method, and its physicochemical properties were characterised using the SEM, DSC, XRD, 1HNMR and FT-IR. In addition, in vitro dissolution and bioavailability (oral and transdermal) experiments were also conducted. The inclusion complex was formed with ES and HP-β-CD at the mass ratio of 11. ES existed in an amorphous form in the inclusion complex. The equilibrium solubility of ES/HP-β-CD inclusion complex in SGF (simulated gastric fluid) and SIF (simulated intestinal fluid) was 50.6 ± 0.11 mg/mL and 75.9 ± 0.38 mg/mL in SGF and SIF, which was 5.93 and 9.96 times higher than that of free ES, respectively. The ES/HP-β-CD inclusion complex had better dissolution ability and transdermal permeability than the free ES.
