Abstract
INTRODUCTION The epidemiological surveillance of mesothelioma incidence is a crucial key for investigating the occupational and environmental sources of asbestos exposure. The median age at diagnosis is generally high, according to the long latency of the disease. The purposes of this study are to analyse the incidence of mesothelioma in young people and to evaluate the modalities of asbestos exposure. METHODS Incident malignant mesothelioma (MM) cases in the period 1993-2018 were retrieved from Italian national mesothelioma registry and analysed for gender, incidence period, morphology and exposure. Age-standardised rates have been calculated and the multiple correspondence analysis has been performed. The association between age and asbestos exposure has been tested by χ2 test. RESULTS From 1993 to 2018, 30 828 incident MM cases have been collected and 1278 (4.1%) presented diagnosis at early age (≤50 years). There is a substantial association between age at diagnosis and the type of asbestos exposure and a significantly lower frequency of cases with occupational exposure to asbestos (497 cases vs 701 expected) in young people has been documented. Paraoccupational and environmental exposure to asbestos have been found more frequent in young MM cases (85 and 93 observed cases vs 52 and 44 expected cases, respectively). CONCLUSIONS Mesothelioma incidence surveillance at population level and the anamnestic individual research of asbestos exposure is a fundamental tool for monitoring asbestos exposure health effects, supporting the exposure risks prevention policies. Clusters of mesothelioma incident cases in young people are a significant signal of a potential non-occupational exposure to asbestos.

Abstract
The study describes the 466 cases of malignant mesotheliomas (MM) collected by the National Mesothelioma Register (ReNaM) in Italy in the period 1993-2018 relating to subjects with exclusive asbestos exposure in merchant or military navy. The cases among maritime workers represent 1.8% of the total cases with defined exposure registred in the ReNaM, of which 212 cases (45.4%) among merchant maritime workers and 254 cases (54.5%) among navy. The distribution by site of mesothelioma showed 453 (97.2%) MM cases of the pleura, 11 (2.3%) of the peritoneum and 2 (0.4%) of the tunica vaginalis of the testis. With regard to occupational exposure, it was classified as certain in 318 (68.2%) cases, probable in 69 (14.8%) cases and possible in 79 (16.9%) cases. Among the 23 classified jobs, the highest percentages of certain exposures are among naval engineers, motor mechanics, machine captains and sailors. Machine crew accounted for 49.3% of the cases, deck crew for 27.6%. All cases began exposure on board between 1926 and 1988. Seamen were exposed to asbestos while at sea by virtue of living onboard ships and from continual release of asbestos fibers due to the motion of a vessel. Epidemiological surveillance through the ReNaM has allowed us to verify among cases in the maritime, navy and merchant marine sectors, that in the past, subjects were exposed regardless of the ship's department where have provided service therefore all these cases must be considered as occupational diseases.

Abstract
OBJECTIVES Workers in the construction industry have been exposed to asbestos in various occupations. In Italy, a National Mesothelioma Registry has been implemented more than 20 years ago. Using cases selected from this registry and exploiting existing control data sets, we estimated relative risks for pleural mesothelioma (PM) among construction workers. DESIGN Case-control study. SETTING Cases from the National Mesothelioma Registry (2000-2018), controls from three previous case-control studies. METHODS We selected male PM incident cases diagnosed in 2000-2018. Population controls were taken from three studies performed in six Italian regions within two periods (2002-2004 and 2012-2016). Age-adjusted and period-adjusted unconditional logistic regression models were fitted to estimate odds ratios (OR) for occupations in the construction industry. We followed two approaches, one (primary) excluding and the other (secondary) including subjects employed in other non-construction blue collar occupations for >5 years. For both approaches, we performed an overall analysis including all cases and, given the incomplete temporal and geographic overlap of cases and controls, three time or/and space restricted sensitivity analyses. RESULTS The whole data set included 15 592 cases and 2210 controls. With the primary approach (4797 cases and 1085 controls), OR was 3.64 (2181 cases) for subjects ever employed in construction. We found elevated risks for blue-collar occupations (1993 cases, OR 4.52), including bricklayers (988 cases, OR 7.05), general construction workers (320 cases, OR 4.66), plumbers and pipe fitters (305 cases, OR 9.13), painters (104 cases, OR 2.17) and several others. Sensitivity analyses yielded very similar findings. Using the secondary approach, we observed similar patterns, but ORs were remarkably lower. CONCLUSIONS We found markedly increased PM risks for most occupations in the construction industry. These findings are relevant for compensation of subjects affected with mesothelioma in the construction industry.

Abstract
BACKGROUND An increased risk of mesothelioma has been reported in various countries for construction workers. The Italian National Mesothelioma Registry, from 1993 to 2018, reported exposure exclusively in the construction sector in 2310 cases. We describe the characteristics of these cases according to job title. METHODS We converted into 18 groups the original jobs (N=338) as reported by ISTAT codes ('ATECO 91'). The exposure level was attributed at certain, probable and possible in accordance with the qualitative classification of exposure as reported in the Registry guidelines. Descriptive analysis by jobs highlights the total number of subjects for each single job and certain exposure, in descending order, insulator, plumbing, carpenter, mechanic, bricklayer, electrician, machine operator, plasterer, building contractor, painter and labourer. RESULTS The cases grow for plumbing in the incidence periods 1993-2018, while, as expected, it decreases for insulator. Within each period considered the most numerous cases are always among bricklayers and labourers, these data confirm the prevalence of non-specialised "interchangeable" jobs in Italian construction sector in the past. CONCLUSIONS Despite the 1992 ban, the construction sector still presents an occupational health prevention challenge, circumstances of exposure to asbestos may still occur due to incomplete compliance with prevention and protection measures.

Abstract
Notwithstanding the ban in 1992, asbestos exposure for workers in the construction sector in Italy remains a concern. The purpose of this study is to describe the characteristics of malignant mesothelioma (MM) cases recorded by the Italian registry (ReNaM) among construction workers. Incident mesothelioma cases with a definite asbestos exposure have been analyzed. Characteristics of cases and territorial clusters of crude rates of MM in construction workers have been described, as well as the relation between asbestos use before the ban and the historical trend of workforce in the construction sector in Italy. ReNaM has collected 31,572 incident MM cases in the period from 1993 to 2018 and asbestos exposure has been assessed for 24,864 (78.2%) cases. An occupational exposure has been reported for 17,191 MM cases (69.1% of subjects with a definite asbestos exposure). Among them, 3574 had worked in the construction sector, with an increasing trend from 15.8% in the 1993–98 period to 23.9% in 2014–2018 and a ubiquitous territorial distribution. The large use of asbestos in construction sector before the ban makes probability of exposure for workers a real concern still today, particularly for those working in maintenance and removal of old buildings. There is a clear need to assess, inform, and prevent asbestos exposure in this sector.

Abstract
The composition of final submaxillary saliva and of whole gland homogenates were compared in rats treated with 14 daily doses of guanethidine (20 mg/kg body weight) and in untreated controls after stimulation with pilocarpine (10 mg/kg) or carbamylcholine (50-100 mg/kg). A 44% reduction in the volume of saliva and elevations in the salivary concentrations of K+, Ca2+ and protein were found in the treated animals after pilocarpine stimulation. Similarly, a 25% reduction in salivary volume and elevations in salivary Ca2+ and protein concentrations were observed following stimulation with carbamylcholine. A less significant elevation in salivary K+ was seen after this secretagogue. The Na+ and protein contents, but not the K+ and Ca2+ contents, were found to be elevated in the glands of the treated animals in the resting (unstimulated) state. After stimulation with the two secretagogues, however, similar changes in glandular Na+ and K+ contents were found in the glands of control and treated animals. The glandular water content was also similar in both types of glands in the resting and stimulated states. It is concluded that a reduced salivary secretion, rather than supersensitivity, is observed in the rat submaxillary gland following chronic guanethidine administration. The drug treatment does not impair the glandular electrolyte changes that occur upon stimulation, but most likely impairs the release of protein from the gland and also transductal K+ transport. Both these effects may result from the depletion of sympathetic neurotransmitter caused by the guanethidine administration.

Abstract
At the end of this survey, several conclusions can be drawn. The relatively small strength losses of the cord in the tire, even after very long road running times, and the corresponding good strength of the individual fibers make it possible to regard as untenable any explanation of fatigue failures by hypotheses relative to molecular structures, molecular forces, or crystallization phenomena. Observations on individual fiber breaks have likewise not contributed much to a better understanding of the causes of the tears. Certain “splitters” (aspects of filament breaks) might perhaps be ascribed to the strongly oriented structure of the fiber itself. Other breaks can very easily be explained by mutual abrasion of fibers; in this manner one can also explain the higher density of broken fibers in the zones of greatest flexing and the concentration of failure in the same zones in separated cords tested on the dynamometer. The fact that cord adhesion shows lower strength in the same zones in the “strip out” tests, requires assuming participation of other causes, e.g., it is necessary to assume the occurrence of separations even of limited extension or widespread tears in the rubber. These kinds of damage occur in tires even when they have sustained markedly different road service. It would doubtless be very interesting to carry out a test with progressively longer road service. In any case, it is quite certain that such damage is present when the mechanical properties of the cord are still very good. It seems therefore, that all observations previously made can be correlated with each other. Fatigue occurs in rubber which, upon cyclic loading, tears between the plies, the cords, and the yarns which form the cord. In addition, it is possible that rubber and adhesive separations set in, since the contact surface is likewise stressed cyclically in a way which can be regarded as chiefly in shear stress. Mutual friction between fibers in the yarns forming the cord is not to be excluded; however, if this should occur independently of other causes, when the adhesion is good and the rubber perfect, then one cannot understand why this process should suddenly lose its intensity, or come to a halt, as is shown by the residual strength in relation to the running time. If this internal process in the cord is excluded, it is possible to point to another mechanism already indicated in the course of the survey. Separations between adhesive and rubber and the tears within the rubber— apart from the fact that they develop heat because of friction—are flaws which continue to grow, and where they contact the fabric, there begins a damaging process due to friction and abrasion because of abnormal movements between yarns and fibers.

Abstract
Abstract
The phenomenon of birefringence, discovered in 1669 by Erasmus Bartholin and later studied by Christian Huygens, is well known for its appearance in transparent crystalline solids. It is to be traced essentially to internal anisotropy of crystals for light propagation, so that under certain conditions a single wave front may give rise to multiple coherent waves which can cause double refraction or other phenomena such as the appearance of fringes varying in brightness and color due to interference of emerging wave fronts. Birefringence may be expressed as the difference of the velocities of propagation in various directions in the birefringent medium and particularly as the difference between the maximum and the minimum velocity or, alternatively, between the maximum and the minimum refractive index or even as the phase difference between emerging waves, given frequently as a number of wavelengths. While true double refraction phenomena may be observed with ordinary light when the difference n1−n2 between the refractive indexes is very high, the interference phenomena may be obtained only with polarized light, but may be observed even with very small differences between indexes. This is not the place to treat extensively general concepts like polarizer, analyzer, ordinary wave, extraordinary wave, uniaxial crystal, biaxial crystal, etc. which can be found in any good optics treatise. Birefringence is not in any way limited to crystalline media, possessing inherent structural anisotropy. It may also appear in bodies which are normally isotropic, when structural anisotropy is caused by external forces. Then birefringence is quantitatively dependent on force intensities, even if not always in an easily detectable way. This is called “accidental birefringence” or “stress-birefringence”. It was observed by Seebeck in 1813, and later studied in 1816 by Brewster for glass. It is observable in many transparent materials. Stress-birefringence is particularly conspicuous in macromolecular substances, including elastomers, vulcanized or not, where it is determined by the orientation of molecular links. This, of course, may not be ascribed altogether to stress, but sometimes also to partial crystallinity. Other phenomena of accidental birefringence may be observed in liquids or in solutions, especially of elastomers, when they are subjected to a velocity gradient, as when flowing through a capillary tube or, more commonly, when sheared between two coaxial cylinders.
