Why are married women working so much?
We study the large observed changes in labor supply by married women in the United States over 1950-1990, a period when labor supply by single women has hardly changed at all. We investigate the effects of changes in the gender wage gap, technological improvements in the production of nonmarket goods and potential inferiority of these goods on understanding this change. We find that small decreases in the gender wage gap can explain simultaneously the significant increases in the average hours worked by married women and the relative constancy in the hours worked by single women, and single and married men. We also find that technological improvements in the household have-for realistic values-too small an impact on married female hours and the relative wage of females to males. Some specifications of the inferiority of home goods match the hours patterns, but have counterfactual predictions for wages and expenditure patterns.Labor supply ; Women - Employment

Pediatric Obesity-Related Asthma: The Role of Nutrition and Nutrients in Prevention and Treatment.
Childhood obesity rates have dramatically risen in numerous countries worldwide. Obesity is likely a factor in increased asthma risk, which is already one of the most widespread chronic respiratory pathologies. The pathogenic mechanism of asthma risk has still not yet been fully elucidated. Moreover, the role of obesity-related inflammation and pulmonary overreaction to environmental triggers, which ultimately result in asthma-like symptoms, and the importance of dietary characteristics is well recognized. Diet is an important adjustable element in the asthma development. Food-specific composition of the diet, in particular fat, sugar, and low-quality nutrients, is likely to promote the chronic inflammatory state seen in asthmatic patients with obesity. An unbalanced diet or supplementation as a way to control asthma more efficiently has been described. A personalized dietary intervention may improve respiratory symptoms and signs and therapeutic response. In this narrative review, we presented and discussed more recent literature on asthma associated with obesity among children, focusing on the risk of asthma among children with obesity, asthma as a result of obesity focusing on the role of adipose tissue as a mediator of systemic and local airway inflammation implicated in asthma regulation, and the impact of nutrition and nutrients in the development and treatment of asthma. Appropriate early nutritional intervention could possibly be critical in preventing and managing asthma associated with obesity among children
Financing COVID-19 Deficits in Fiscally Dominant Economies: Is The Monetarist Arithmetic Unpleasant?
Noninvasive monitoring of cancer therapy induced activated T cells using [F-18]FB-IL-2 PET imaging
Cancer immunotherapy urgently calls for methods to monitor immune responses at the site of the cancer. Since activated T lymphocytes may serve as a hallmark for anticancer responses, we targeted these cells using the radiotracer N-(4-[F-18] fluorobenzoyl)-interleukin-2 ([F-18] FB-IL-2) for positron emission tomography (PET) imaging. Thus, we noninvasively monitored the effects of local tumor irradiation and/or immunization on tumor-infiltrating and systemic activated lymphocytes in tumor-bearing mice. A 10- and 27-fold higher [F-18] FB-IL-2 uptake was observed in tumors of mice receiving tumor irradiation alone or in combination with immunization, respectively. This increased uptake was extended to several non-target tissues. Administration of the CXCR4 antagonist AMD3100 reduced tracer uptake by 2.8-fold, indicating a CXCR4-dependent infiltration of activated T lymphocytes upon cancer treatment. In conclusion, [F-18] FB-IL-2 PET can serve as a clinical biomarker to monitor treatment-induced infiltration of activated T lymphocytes and, on that basis, may guide cancer immunotherapies
