Alopecia is a common disease affecting more than half of the world total number of people. Alopecia exists in different types, but one of the most common of these types is the Androgenic Alopecia which has affected approximately 51% of the total number of males ranging between the age bracket of 40 years and 75 years. This type of alopecia is more common in females who are above the age of 65 years and above. Despite this widespread effect, much has not been done regarding identifying the possible drugs for treating this disease...

Steel ball surface-defect inspection was performed by using a new saddle-type eddy current sensor (SECS), which included a saddle coil and a signal conditioning circuit. The saddle coil was directly wound on the steel ball's outer bracket in a semi-circumferential direction. Driven by a friction wheel, the test steel ball rotated in a one-dimensional direction, such that the steel ball surface was fully scanned by the SECS. There were two purposes for using the SECS in the steel ball inspection system: one was to reduce the complexity of the unfolding wheel of the surface deployment mechanism, and the other was to reduce the difficulty of sensor processing and installation...

This study aimed to evaluate the antifungal, antioxidative, and genoprotective potentials of various extracts of Daedaleopsis confragosa fruiting bodies and mycelia. The extracts exhibited weak fungistatic and an absence of any fungicidal activities against 7 important animal and human pathogens. Although mycelial extracts, especially the hot water extract, were more effective antifungal agents than basidiocarp extracts, they were significantly weaker than the commercial antimycotic ketoconazole. The tested extracts reduced DPPH radicals to various extents, depending on the material used for extraction and the solvent...

Complexation with methyl groups produces the most toxic form of mercury, especially because of its capacity to bioconcentrate in living tissues. Understanding and integrating methylation and demethylation processes is of the utmost interest in providing geochemical models relevant for environmental assessment. In a first step, we investigated methylation at equilibrium, by selecting the thermodynamic properties of different complexes that form in the chemical system Hg-SO3-S-Cl-C-H2O. The selection included temperature dependencies of the equilibrium constants when available...

This study examines the effect of employment on elderly men's health. A typical OLS analysis yields a positive relationship between employment and health for individuals in their sixties. Causality, however, is difficult to infer because healthier individuals are more capable of working than others. To overcome this endogeneity problem, this paper exploits the increase in the full retirement age for men in Israel from sixty-five to sixty-seven in 2004. After this change, the employment rate of men in this age bracket jumped significantly compared to the last cohort that was able to retire at sixty-five...

Photoisomerization of 2,2'-, 3,3'- and 4,4'-difluorostilbene (F2, F3, F4, respectively) in n-hexane, perfluoro-n-hexane and acetonitrile is studied with broadband transient absorption (TA) and femtosecond stimulated Raman (FSR) spectroscopy, and by DFT/TDDFT calculations. F2 and F3 possess three rotamers (rotational isomers) each, while F4 has one single conformation only. These differences are reflected in TA and FSR spectra. Thus, F4 reveals a mono-exponential decay of TA with τ1 =172 ps in n-hexane, as expected for a single species...
