Studio antropologico dei resti rinvenuti in una tomba del sito di Vico III Lanusei a Cagliari

The archaeological excavations in Vico III Lanusei, within the urban area of Cagliari, were carried out between 1996 and 1997. The work was supervised by Donatella Mureddu of the Archaeological Authorities for the Provinces of Cagliari and Oristano. The stratigraphic excavation of the site has brought to light various inhabited and funerary areas, testifying to their use from the late republican period through to the Middle Ages. Differing types of burial have been discovered in the area. In particular, one was dug directly into the rock, three were in coffins and two were Capuchin type burials. In this paper a description is provided of the results of the anthropological study of the human skeletal remains found in the burial dug directly into the rock. In the grave there were four infants in a supine position, placed on a later dates

C- Line Polymorphism in Human Populations

Data on C- line terminations as established by Plato [1] are reported for various populations with reference to the radial terminations/ulnar terminations ratio. The examined populations are heterogeneous and can be divided between those with a Radial type/Ulnar type ratio less than 1 and those with a ratio greater than 1

Bioseparation of Four Proteins from Euphorbia characias Latex: Amine Oxidase, Peroxidase, Nucleotide Pyrophosphatase/Phosphodiesterase, and Purple Acid Phosphatase

This paper deals with the purification of four proteins from Euphorbia characias latex, a copper amine oxidase, a nucleotide pyrophosphatase/phosphodiesterase, a peroxidase, and a purple acid phosphatase. These proteins, very different in molecular weight, in primary structure, and in the catalyzed reaction, are purified using identical preliminary steps of purification and by chromatographic methods. In particular, the DEAE-cellulose chromatography is used as a useful purification step for all the four enzymes. The purification methods here reported allow to obtain a high purification of all the four proteins with a good yield. This paper will give some thorough suggestions for researchers busy in separation of macromolecules from different sources

Does the longevity of the Sardinian population date back to Roman times? A comprehensive review of the available evidence

The discovery early in this century of the exceptional longevity of the Sardinian population has given new impetus to demographic studies of this phenomenon during the classical period. In the 1970s, it was hypothesised that the average mortality rate in Roman Sardinia was lower than in metropolitan Rome itself, postulating an ancient precedent for the remarkable longevity observable nowadays in the island's population. In the present study, the available evidence was examined in order to test this hypothesis. Literary, juridical, epigraphic, papyrological, anthropological and archaeological sources regarding the population of the Roman Empire, including Sardinia, were retrieved by accessing Science Direct, PubMed, Scopus and Google Scholar databases, as well as regional libraries, regardless of time limitation, and were independently reviewed by the authors. For Roman Sardinia, only funerary epitaphs were retrieved, in contrast with the numerous sources available for the whole Roman Empire. Inscriptions revealing the existence of three alleged nonagenarians, two centenarians, two ultracentenarians and one supercentenarian were found, corresponding to 2% in a total of 381 inscriptions. The majority were located in a highly Romanised rural area of central-western Sardinia. However, the ages reported in the epitaphs may be inaccurate because of the influence of confounders such as age rounding, approximations and/or amplifications, and are unrelated to the total number of inhabitants. In conclusion, the funerary evidence, the only available data from Roman Sardinia, is too weak to estimate the life expectancy of the local ancient population and cannot offer valuable arguments to support the hypothesis that exceptional longevity has been a Sardinian trait since Roman times

Does Vitamin E or Vitamin E plus Selenium improve reproductive performance of rams during hot weather

The objective of this study was to determine the effect of Vitamin E (Vit E) and Selenium (Se) on semen quality, sexual activity, packed cell volume (PCV), and white blood cell counts (WBC) of Awassi rams during the hot season. Twelve Awassi rams were subdivided into three groups and treated for 90 days. Rams in the 1st group (T1) were treated twice weekly with 175 mg/ram vitamin E at intervals of 12h; rams in the 2nd group (T2) were treated on the same schedule with 70 mg/ram vitamin E plus 2800 mg selenium; and rams in 3rd group (T3) served as controls. Sperm quality (percentage of motile cells and percentage of morphologically normal cells) and quantity (sperm volume, and concentration) were recorded weekly. Sexual activity was tested by using the pen libido test at monthly intervals. Blood samples were taken before treatment and after the 1st, 2nd, and 3rd months. Semen quality was significantly affected by treatments: the ejaculate volume increased in T2 vs T1, and T3; mass activity and individual motility were increased in T1 and T2 vs T3. Sperm concentration was increased in T2 and T1 vs T3, and the percentage of dead and abnormal spermatozoa was reduced in T1 and T2 vs T3, though the differences were not statistically significant. Pen libido test showed reduced reaction time for the first mount in the 1st month in T2 and T1 vs T3. The number of serves was increased in groups T1 and T2 vs T3. There were no significant differences in PCV among groups. After 3 months from the beginning of treatments, the percentage of lymphocytes increased in T1 and T2 vs. T3, while the percentage of neutrophils was reduced in T2 vs T3 in the 2nd and 3rd months. The results of this experiment indicate that treatments with vitamin E alone or in combination with selenium improved semen characteristics and reproductive performance of Awassi rams during the hot season

Body Composition Variations in Ageing

Age-related physiological variations of body composition concern both the fat-free mass (FFM) and the fat mass (FM). These variations expose the elderly person to the risk of malnutrition and could lead to conditions of disability. This paper aims to review the current state of knowledge on body composition in the aged population. The pattern of qualitative variations in body composition in old age is fairly well defined. In adulthood, the physiological variation of body mass involves a first increasing phase followed by a decreasing trend. The reduction is due mainly to the loss of fat-free mass, especially muscle mass. Total body water and bone mass also decrease. Fat mass tends to decrease and the reduction seems to be due mainly to the loss of subcutaneous fat. The quantitative aspects of the age of onset, rate and intensity of the physiological variations are still not completely clear. This poor quantitative definition is due to the variable and multifactorial phenomenology of ageing, the heterogeneity of assessment techniques and sampling models, and the limited number of empirical observations in oldest-old individuals

Patterns of Hand Variation – New Data on a Sardinian Sample

This study is an analysis of the patterns of variation of the human hand, particularly the metric characters of palm, fingers and distal phalanges. Anthropometric measurements were performed on 146 Sardinian men and women, aged 21 to 31 years. The data were analyzed by inferential statistics (paired Student’s t test, analysis of variance), and Principal Components Analysis. The results indicate that size factors are the principal source of variation. A residual adimensional component of variability is related to diversification between the fingers as a whole and the distal phalanges, and between the thumb and the other fingers. Sexual dimorphism is evident. Men present greater dimensions and greater relative length of the thumb with respect to the other fingers than women

Somatotype in Elderly Type 2 Diabetes Patients

Somatotyping is a practical technique for the description of physique. Individuals with Type 2 diabetes are characterized by physical peculiarities, such as overweight, obesity and a central pattern of body fat distribution. Somatotype applications to diabetes are limited. The objective of this study is to describe the somatotype of elderly type 2 diabetes patients. The sample consisted of 110 patients with type 2 diabetes (45 men, mean age 69.4±7.0 years; 65 women, mean age 72.9±7.1 years). The pathological subjects were compared with a control group consisting of 280 healthy individuals (134 men, mean age 74.2±7.3 years; 146 women, mean age 74.9±7.4 years). The Heath-Carter somatotype was applied. Diabetic men and women (mean somatotype, respectively: 6.8–5.6–0.6 and 8.6–6.4–0.2) presented significantly higher values of endomorphy than the controls (p=0.043 in men, p=0.003 in women); men also had a lower mesomorphic component (p=0.000). The somatotype method revealed physical peculiarities in type 2 diabetes patients. The marked endomorphy in the pathological individuals can be related to general fatness, which is a well known disease risk factor. The somatotype appears to be a suitable technique for the assessment of physique in type 2 diabetes patients
