Understanding Despair: The Role of Physical Pain
In the United States, mortality due to alcohol, opioid overdose, and suicide has increased dramatically in the last decades. These deaths of despair have been the focus of recent and fast-growing literature. Yet little is known about the factors that are involved in despair. This article moves this area of research forward by highlighting the role that physical pain plays in the deaths of despair. This piece critically analyses the link between physical pain, the psychological states that precede pain, and the premature mortality that follows physical pain as well as the bidirectional relationships among these aspects

Having less than others is painful: Income rank and pain around the world
Physical pain is a pressing issue for scientists and policymakers. Yet evidence on the psychosocial factors of pain is limited. Using data from 146 countries (N = 1.3 million individuals), this article documents the role of income comparisons on physical pain. Specifically, this study shows that income rank (i.e., the ordinal position of a person’s income within a comparison group) is linked to physical pain above and beyond absolute income. This effect is identical in rich and poor nations. The negative emotions that result from a disadvantaged relative standing in the income hierarchy may explain these findings. This article documents a new kind of evidence on the power of income comparisons and highlights the role that psychosocial factors may play in physical pain
Interleukin-2 promoter activation in T-cells expressing activated Ha-ras.
Antigen triggering of the T-cell receptor results in an accumulation of activated GTP-bound p21ras protein. To assess the role of ras protein in T-cell activation we have cotransfected the murine thymoma line EL4 with a construct capable of expressing a constitutively active, oncogenic form of Ha-ras and a reporter construct containing the human interleukin-2 promoter fused upstream of the bacterial gene for chloramphenicol acetyltransferase. We show that the ras oncoprotein contributes to interleukin-2 promoter activation. Its pattern of synergism with a calcium ionophore or the lymphokine interleukin-1 indicates that it replaces a signal mediated by protein kinase C. Interleukin-2 promoter activity in the presence of ras oncoprotein was inhibited by H7, a potent inhibitor of protein kinase C, but not by HA1004, an inhibitor of cyclic nucleotide-dependent kinase, suggesting that protein kinase C mediates the ras effect. In addition, we show that in these cells, expression of activated ras results in activation of a synthetic promoter containing several copies of an NF kappa B binding site
Multianalytical non-invasive characterization of ‘Mater Boni Consilii’ iconography oil painting
This paper presents the results of non-invasive diagnostic investigations performed on the canvas oil painting depicting the Marian iconography “Mater Boni Consilii”. The painting, whose author and origin are unknown, was found in an old shop in Florence following the overflowing of the Arno River in 1966. In order to define the importance of the artwork, a multianalytical analysis was performed on the painting, using multispectral imaging, X-ray fluorescence (XRF), and Fourier Transform Infrared Spectroscopy (FTIR-ATR) for the definition of materials, with a particular focus on the identification of pigments. The results allowed for the drawing up of a color palette, composed mainly of ochre and earth pigments, cinnabar, lithopone, lead white, and ultramarine pigments. After cross-referencing the acquired information with other findings, it was possible to place the painting in the period between the end of the XIXth and the beginning of the XXth centuries
Effects of treatment modalities for Graves' hyperthyroidism on Graves' orbitopathy: a 2015 Italian Society of Endocrinology Consensus Statement.
Effectiveness of Lactobacillus-containing vaginal tablets in the treatment of symptomatic bacterial vaginosis
AbstractThe purpose of this study was to determine the effectiveness of Lactobacillus-containing vaginal tablets in the treatment of bacterial vaginosis (BV) and in the restoration of a healthy vaginal flora. Thirty-nine women with BV were enrolled in a double-blind, placebo-controlled clinical trial. Patients received either one Lactobacillus-containing tablet or placebo daily for 7 days. Clinical criteria, vaginal Gram stain scores and symptoms were compared with those at the initial visit and those at completion of therapy and 2 weeks later. After completion of therapy, all of the patients in the Lactobacillus-treated group (n = 18) were free of BV, showing a normal (83%) or intermediate (17%) vaginal flora, as compared with only two patients free of BV with intermediate flora (12%) from among the 16 placebo-treated women (p <0.001). Two weeks after completion of therapy, treatment was successful (score <7) in 61% of Lactobacillus-treated patients as compared with 19% of those in the placebo group (p <0.05). In the treatment group, the total number of symptomatic patients and the intensity of their symptoms, in particular vaginal malodour, were significantly reduced at both follow-up visits. The data indicate that intravaginal administration of exogenous selected strains of lactobacilli can restore a normal vaginal microbiota and be used in treating bacterial vaginosis

The effect of adverse employment circumstances on physical pain: Evidence from Australian panel data
Physical pain is a common health problem with great public health implications. Yet evidence on whether adverse employment circumstances shape physical pain is limited. Using longitudinal data from 20 waves (2001−2020) from the Household, Income and Labour Dynamics of Australia Survey (HILDA; N = 23,748), a lagged design, Ordinary Least Squares (OLS) regressions as well as multilevel mixed effect linear regressions, we investigated the association between past accumulated unemployment and recent employment circumstances with physical pain. We found that adults who spent more years unemployed and looking for work subsequently reported greater physical (b = 0.034, 95% CI = 0.023, 0.044) and pain interference (b = 0.031, 95% CI = 0.022, 0.038) than those who spent fewer years unemployed. We also found that those experiencing overemployment (working full-time while wanting to work fewer hours) and underemployment (working part-time while wanting to work more hours) reported greater subsequent physical pain (overemployment: b = 0.024, 95% CI = 0.009, 0.039; underemployment: b = 0.036, 95% CI = 0.014, 0.057) and pain interference (overemployment: b = 0.017, 95% CI = 0.005, 0.028; underemployment: b = 0.026, 95% CI = 0.009, 0.043) than those content with their working hours. These results held after controlling for socio-demographic characteristics, occupation, and other health-related factors. These findings are consistent with recent work that suggested that psychological distress can influence physical pain. Understanding how adverse employment circumstances impact physical pain is crucial to the design of health promotion policies

Global pain levels before and during the COVID-19 pandemic
Physical pain has trended upward globally over the last decade. Here, we explore whether the COVID-19 pandemic modified this alarming trend. We used data from 146 countries worldwide (510,247 respondents) to examine whether pain levels changed during the COVID-19 pandemic. Adjusted regressions across countries revealed that 33.3% of people were in pain in 2019, 32.8% in 2020, 32.5% in 2021, and 34.1% in 2022. The change in pain from 2019 to each of the pandemic years was not statistically significant. This suggests that, on average, there was no significant change in pain during the pandemic. However, from 2019 to 2020 there was a significant decline in pain among individuals over 55 years of age, those who were widowed, and those without children in the household. On a global scale, the COVID-19 pandemic was not associated with a significant change in pain levels. The concerning pre-pandemic elevation in global pain continued during this challenging period
Natural based products for cleaning copper and copper alloys artefacts
Copper alloys objects can deteriorate their conservation state through irreversible corrosion. Since in the cultural heritage field every artefact is unique and any loss irreplaceable, solutions for conservation are needed. Hence, there is the necessity to stop the corrosion process with a suitable cleaning and conservation process to avoid further degradation processes without changing its morphological aspect. Chelating solutions are commonly used in chemical cleaning, mainly sodium salts of ethylenediaminetetraacetic acid (EDTA). However, it is resistant to water purification procedures and is not biodegradable. The goal of this study was to see if applying an ecologically friendly chelating agent as an alternative to EDTA cleaning procedures for cultural heritage was suitable. In this study were chosen six natural-based chelators that could be a new green non-toxic alternative to EDTA in corrosion-inhibiting properties. They were tested for cleaning copper artefacts exposed to atmospheric environment in polluted areas. The study considered four amino acids, a glucoheptonate (CSA) and an industrial green chelator (GLDA). The effectiveness was tested on corrosion copper compounds and on laboratory corroded copper sheets. Finally, the cleaning efficacy was tested on four Roman coins and a modern copper painting. To define the cleaning efficacy, surface analytical investigations have been carried out by means ICP-OES, UV-VIS, µ-Raman, spectro-colorimetry, XRD and FTIR. Among the amino acids, alanine was the most effective, showing an unaltered noble patina and a good effective copper recovery from corrosion patinas
Surface plasmon resonance assay for label-free and selective detection of hiv-1 p24 protein
The early detection of the human immunodeficiency virus (HIV) is of paramount importance to achieve efficient therapeutic treatment and limit the disease spreading. In this perspective, the assessment of biosensing assay for the HIV-1 p24 capsid protein plays a pivotal role in the timely and selective detection of HIV infections. In this study, multi-parameter-SPR has been used to develop a reliable and label-free detection method for HIV-1 p24 protein. Remarkably, both physical and chemical immobilization of mouse monoclonal antibodies against HIV-1 p24 on the SPR gold detecting surface have been characterized for the first time. The two immobilization techniques returned a capturing antibody surface coverage as high as (7.5 ± 0.3) × 1011 molecule/cm2 and (2.4 ± 0.6) × 1011 molecule/cm2, respectively. However, the covalent binding of the capturing antibodies through a mixed self-assembled monolayer (SAM) of alkanethiols led to a doubling of the p24 binding signal. Moreover, from the modeling of the dose-response curve, an equilibrium dissociation constant KD of 5.30 × 10−9 M was computed for the assay performed on the SAM modified surface compared to a much larger KD of 7.46 × 10−5 M extracted for the physisorbed antibodies. The chemically modified system was also characterized in terms of sensitivity and selectivity, reaching a limit of detection of (4.1 ± 0.5) nM and an unprecedented selectivity ratio of 0.02
