“La ministro è incinta”: A twitter account of women's job titles in Italian

We analyze the use of feminine forms indicating professions and roles held by women in Italian. The study is based on Twitter and collects data from 2006 to 2021. This allows us to set up both the quantitative and the qualitative study in a diachronic perspective on a time span of 15 years. We observe the distribution over time of a selection of feminine job titles (i.e., minister, mayor, rector, engineer and lawyer), compared to their masculine counterparts, distinguishing in particular the following cases: use of marked forms and use of semi-marked forms. The analysis shows that the trend of using feminine (i.e. marked) forms is generally growing through time. However, the unbalance between the actual number of women employed in some professions and the use of the correspondent feminine job title is wide

Selective agonists of estrogen receptor isoforms : new perspectives for cardiovascular disease

The cloning of estrogen receptors (ERs) and generation of ER-deficient mice have increased our understanding of the molecular mechanisms underlying the cardiovascular effects of estrogen. It is conceivable that clinical trials of estrogens so far failed to improve cardiovascular health because of the poor ER isoform selectivity and tissue specificity of endogenous hormones as well as incorrect treatment timing and regimens. Tissue-selective ER modulators (SERMs) may be safer agents than endogenous estrogens for cardiovascular disease. Yet, designing isoform-selective ER ligands (I-SERMs) with agonist or antagonist activity is required to pursue improved pharmacological control of ERs, especially taking into account emerging evidence for the beneficial role of vascular ER alpha activation. Ideally, the quest for unique ER ligands targeted to the vascular wall should lead to compounds that merge the pharmacological profiles of SERM and I-SERM agents. This review highlights the current bases for and approaches to selective ER modulation in the cardiovascular system

Antiplatelet and anticoagulant therapy for non-ST-elevation acute coronary syndromes in a general hospital

Aim: To audit compliance with the 2011 European Society of Cardiology (ESC) guidelines for prescribing antiplatelet and anticoagulant therapy in patients diagnosed with non-ST-elevation acute coronary syndromes (NSTE-ACS). Methods: Five-month audit at Cardiac Catheterisation Suite, Mater Dei Hospital, Malta. A data collection form for inpatients diagnosed with NSTE-ACS was developed, psychometrically evaluated and completed for each patient by the investigator. Comparative analysis to assess whether these patients were being managed according to the guidelines was undertaken. Results: 165 patients were recruited; 73% were male, 37% were between 66 and 75 years and 44% were active smokers. The most common risk factors for cardiovascular disease in these patients were hypertension (27%), dyslipidemia and obesity (both 16%). 41% of the patients underwent a percutaneous coronary intervention, either ad hoc (34%) or elective (7%). Compliance to guidelines for prescription of aspirin and clopidogrel 300mg loading dose was 95% and 88% respectively. Compliance to guidelines for prescription of aspirin and clopidogrel 75mg daily maintenance dose was 97% and 96% respectively. Compliance to guidelines for prescription of proton pump inhibitors (PPIs) in patients receiving dual antiplatelet therapy (DAPT) was only 19%; 81% of the patients were prescribed omeprazole against guideline recommendations. Compliance to guidelines for prescription of anticoagulation therapy was 95% with respect to prescription of heparin treatment in combination with DAPT. Compliance to guidelines for prescription of enoxaparin was 81%. Compliance to guidelines for other antiplatelet and anticoagulant drugs recommended in the guidelines, including ticagrelor, prasugrel, glycoprotein IIb/IIIa receptor antagonists, fondaparinux and bivalirudin, was not measured. Conclusions: Prescription of antiplatelet and anticoagulant therapy for NSTE-ACS in Malta is predominantly in accordance with ESC guidelines. Alternative antiplatelet and anticoagulant drugs and PPIs should be included in the Maltese hospital formulary to improve NSTE-ACS management in line with guideline recommendations.peer-reviewe

Mono- and disubstituted-3,8-diazabicyclo[3.2.1]octane derivatives as analgesics structurally related to epibatidine: synthesis, activity, and modeling.

A series of 3,8-diazabicyclo[3.2.1]octanes substituted either at the 3 position compounds 1) or at the 8 position (compounds 2) by a chlorinated heteroaryl ring were synthesized, as potential analogues of the potent natural analgesic epibatidine. When tested in the hot plate assay, the majority of the compounds showed significant effects, the most interesting being the 3-(6-chloro-3-pyridazinyl)-3,8-diazabicyclo[3.2.1]octane (la). At a subcutaneous dose of 1 mg/kg, 1a induced a significant increase in the pain threshold, its action lasting for about 45 min. 1a also demonstrated good protection at a dose of 5 mg/kg in the mouse abdominal constriction test, while at 20 mg/kg it completely prevented the constrictions in the animals. Administration of naloxone (1 mg/kg ip) did not antagonize its antinociception while mecamylamine (2 mg/kg ip) did, thus suggesting the involvement of the nicotinic system in its action. Binding studies confirmed high affinity for the \u3b1\u3b22 nAChR subtype (K(i) = 4.1\ub10.21 nM). nAChR functional activity studies on three different cell lines showed that 1a was devoid of any activity at the neuromuscular junction. Finally, due to the analogy in their pharmacological profile with that of epibatidine, compounds were compared from a structural and conformational point of view through theoretical calculations and high-field 1H NMR spectroscopy. Results indicate that all of them present one conformation similar to that of epibatidine

Anti-müllerian hormone is not associated with cardiometabolic risk factors in adolescent females

<p>Objectives: Epidemiological evidence for associations of Anti-Müllerian hormone (AMH) with cardiometabolic risk factors is lacking. Existing evidence comes from small studies in select adult populations, and findings are conflicting. We aimed to assess whether AMH is associated with cardiometabolic risk factors in a general population of adolescent females.</p> <p>Methods: AMH, fasting insulin, glucose, HDLc, LDLc, triglycerides and C-reactive protein (CRP) were measured at a mean age 15.5 years in 1,308 female participants in the Avon Longitudinal Study of Parents and Children (ALSPAC). Multivariable linear regression was used to examine associations of AMH with these cardiometabolic outcomes.</p> <p>Results: AMH values ranged from 0.16–35.84 ng/ml and median AMH was 3.57 ng/ml (IQR: 2.41, 5.49). For females classified as post-pubertal (n = 848) at the time of assessment median (IQR) AMH was 3.81 ng/ml (2.55, 5.82) compared with 3.25 ng/ml (2.23, 5.05) in those classed as early pubertal (n = 460, P≤0.001). After adjusting for birth weight, gestational age, pubertal stage, age, ethnicity, socioeconomic position, adiposity and use of hormonal contraceptives, there were no associations with any of the cardiometabolic outcomes. For example fasting insulin changed by 0% per doubling of AMH (95%CI: −3%,+2%) p = 0.70, with identical results if HOMA-IR was used. Results were similar after additional adjustment for smoking, physical activity and age at menarche, after exclusion of 3% of females with the highest AMH values, after excluding those that had not started menarche and after excluding those using hormonal contraceptives.</p> <p>Conclusion: Our results suggest that in healthy adolescent females, AMH is not associated with cardiometabolic risk factors.</p&gt

TREM2 activation on microglia promotes myelin debris clearance and remyelination in a model of multiple sclerosis

Multiple sclerosis (MS) is an inflammatory, demyelinating, and neurodegenerative disease of the central nervous system (CNS) triggered by autoimmune mechanisms. Microglia are critical for the clearance of myelin debris in areas of demyelination, a key step to allow remyelination. TREM2 is expressed by microglia and promotes microglial survival, proliferation, and phagocytic activity. Herein we demonstrate that TREM2 was highly expressed on myelin-laden phagocytes in active demyelinating lesions in the CNS of subjects with MS. In gene expression studies, macrophages from subjects with TREM2 genetic deficiency displayed a defect in phagocytic pathways. Treatment with a new TREM2 agonistic antibody promoted the clearance of myelin debris in the cuprizone model of CNS demyelination. Effects included enhancement of myelin uptake and degradation, resulting in accelerated myelin debris removal by microglia. Most importantly, antibody-dependent TREM2 activation on microglia increased density of oligodendrocyte precursors in areas of demyelination, as well as the formation of mature oligodendrocytes thus enhancing remyelination and axonal integrity. These results are relevant as they propose TREM2 on microglia as a potential new target to promote remyelination

Reduced Estradiol-Induced Vasodilation and Poly-(ADP-Ribose) Polymerase (PARP) Activity in the Aortas of Rats with Experimental Polycystic Ovary Syndrome (PCOS)

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder characterized by hyperandrogenism and insulin resistance, both of which have been connected to atherosclerosis. Indeed, an increased risk of clinical manifestations of arterial vascular diseases has been described in PCOS. On the other hand endothelial dysfunction can be detected early on, before atherosclerosis develops. Thus we assumed that vascular dysfunction is also related directly to the hormonal imbalance rather than to its metabolic consequences. To detect early functional changes, we applied a novel rodent model of PCOS: rats were either sham operated or hyperandrogenism was achieved by implanting subcutaneous pellets of dihydrotestosterone (DHT). After ten weeks, myograph measurements were performed on isolated aortic rings. Previously we described an increased contractility to norepinephrine (NE). Here we found a reduced immediate relaxation to estradiol treatment in pre-contracted aortic rings from hyperandrogenic rats. Although the administration of vitamin D3 along with DHT reduced responsiveness to NE, it did not restore relaxation to estradiol. Poly-(ADP-ribose) polymerase (PARP) activity was assessed by poly-ADP-ribose immunostaining. Increased PAR staining in ovaries and circulating leukocytes from DHT rats showed enhanced DNA damage, which was reduced by concomitant vitamin D3 treatment. Surprisingly, PAR staining was reduced in both the endothelium and vascular smooth muscle cells of the aorta rings from hyperandrogenic rats. Thus in the early phase of PCOS, vascular tone is already shifted towards vasoconstriction, characterized by reduced vasorelaxation and vascular dysfunction is concomitant with altered PARP activity. Based on our findings, PARP inhibitors might have a future perspective in restoring metabolic disorders in PCOS
