14C dates from Tel Rehov: Iron-Age chronology, pharaohs, and Hebrew kings.

Stratified radiocarbon dates provide an independent chronological link between archaeological layers and historical data. The invasion by Pharaoh Shoshenq I (Shishak) is a key historical synchronism, approximately 925 B.C.E., mentioned in both Egyptian inscriptions and the Hebrew Bible. The list of places raided by Shoshenq, mentioned at Karnak (Egypt), includes Rehov (Israel). The site yielded a consistent series of radiocarbon dates from the 12th to 9th century B.C.E. Our results (i) suggest a revised Iron-Age chronology; (ii) date an archaeological stratum to Shoshenq's campaign; (iii) indicate the similarity of "Solomonic" and "Omride" pottery; and (iv) provide correlation with Greece and Cyprus.

Chronology for the Aegean Late Bronze Age 1700-1400 B.C.

Radiocarbon (carbon-14) data from the Aegean Bronze Age 1700-1400 B.C. show that the Santorini (Thera) eruption must have occurred in the late 17th century B.C. By using carbon-14 dates from the surrounding region, cultural phases, and Bayesian statistical analysis, we established a chronology for the initial Aegean Late Bronze Age cultural phases (Late Minoan IA, IB, and II). This chronology contrasts with conventional archaeological dates and cultural synthesis: stretching out the Late Minoan IA, IB, and II phases by approximately 100 years and requiring reassessment of standard interpretations of associations between the Egyptian and Near Eastern historical dates and phases and those in the Aegean and Cyprus in the mid-second millennium B.C.

Membrane adsorption with direct cell culture combined with reverse transcription-PCR as a fast method for identifying enteroviruses from sewage.

We present a new approach for the detection and identification of enteroviruses concentrated and isolated from sewage. Samples were collected from two study sites located at Nicosia and Limassol sewage treatment plants in Cyprus. Viruses were adsorbed to cellulose nitrate membrane filters, cultured directly from the membrane filters by using the VIRADEN method, and identified by reverse transcription-PCR, followed by 5' untranslated region (5'-UTR) restriction fragment length polymorphism (RFLP) analysis and partial sequencing of the VP1 protein coding region. Initial subgrouping based on the HpaII restriction profile showed that all of the isolates except one belonged to the same genetic subcluster. Partial VP1 sequencing revealed that most isolates belonged to serotypes coxsackie B4 (42.5%) and coxsackie Alpha9 (30%), whereas coxsackie B2 (17.5%) and coxsackie B1 (3%) isolates were less frequently observed. One poliovirus type 2 isolate (2.5%) of vaccine origin was also found. The HpaII digests predicted the genetic subcluster for all isolates. They also accurately differentiated the isolates as nonpolio or polio isolates. This approach seems to be very promising for environmental surveillance of enterovirus circulation and epidemiology, with all of the significant effects that this entails for public health. Partial VP1 sequencing is efficient for molecular serotyping of enteroviruses, while 5'-UTR RFLP analysis with HpaII can also be considered an asset for the initial subclassification of enterovirus isolates.

Humoral response in Toscana virus acute neurologic disease investigated by viral-protein-specific immunoassays.

The Toscana virus (family Bunyaviridae, genus Phlebovirus) is the only sandfly-transmitted virus that demonstrates neurotropic activity. Clinical cases ranging from aseptic meningitis to meningoencephalitis caused by Toscana virus are yearly observed in central Italy during the summer, and several cases have been reported among tourists returning from zones of endemicity (Italy, Portugal, Spain, and Cyprus). In Toscana virus patients, immunoglobulin M (IgM) antibodies, usually present at the onset of symptoms, can reveal elevated titers by enzyme-linked immunosorbent assay and can persist for at least 1 year. IgG antibodies can be absent at the onset of symptoms: titers rise in convalescent sera and persist for many years. At least five proteins have been identified in Toscana virus-infected cells: nucleoprotein N, glycoproteins G1 and G2, a large protein (L) assumed to be a component of the polymerase, and two nonstructural proteins, NSm and NSs. We report results of a study on the antibody response to individual viral proteins in patients with Toscana virus-associated acute neurologic disease. Immunoblotting and semiquantitative radioimmunoprecipitation assay (RIPA) allow identification of nucleoprotein N as the major antigen responsible for both IgM and IgG responses. Antibodies to proteins other than nucleoprotein N are detected only by RIPA. Antibodies to glycoproteins are detected in about one-third of patients, and whereas their presence always predicts neutralization, some serum samples with neutralizing activity have undetectable levels of antibodies to G1-G2. Antibodies to nonstructural proteins NSm and NSs are also identified. The results obtained raise some questions about antigenic variability and relevant neutralization epitopes of Toscana virus.

Rapid identification of Toscana virus by nested PCR during an outbreak in the Siena area of Italy.

The sand fly-transmitted Toscana virus is recognized as an etiologic agent of an aseptic meningitis with a long convalescence. This infection has been reported overall in many tourists or in a seronegative population circulating in endemic Mediterranean areas (Italy, Portugal, Egypt, and Cyprus). We report a cluster of acute Toscana virus infections in the local population during the summer of 1995. Twenty-one clinical cases of meningitis were investigated for the presence of Toscana virus by nested PCR performed on the S segment of the virus RNA extracted from cerebrospinal fluid samples.

Identification of encephalomyocarditis virus in clinical samples by reverse transcription-PCR followed by genetic typing using sequence analysis.

The objective of the present study was to gain a better understanding of the epidemiology of encephalomyocarditis virus (EMCV) infections in pigs by applying molecular techniques. The diagnostic potential of a reverse transcription-PCR (RT-PCR) targeting 286 nucleotides at the 3' end of the gene which encodes the viral polymerase was assessed with experimental and field samples. In addition, the use of the amplified sequences for an epidemiological study was evaluated. The heart was clearly shown to be the most suitable organ. The detection limit was determined to be 1 viral particle in 100 mg of heart tissue. The sensitivity and specificity of the assay on the basis of the results obtained in this study were 94 and 100%, respectively. Phylogenetic analysis of the amplified sequences classified EMCVs in two distinct lineages. Group A consists of the reference strain ATCC 129B, all isolates collected between 1991 and 1994 in Belgium in association with reproductive failure, and all Greek isolates. All Belgian isolates collected since the first isolation of EMCV in relation to myocardial failure in fatteners in Belgium group together with the isolates from Cyprus (1996 and 1997), Italy (1986 to 1996), and France (1995) in group B irrespective of their pathogenicity. The analyzed part of the 3D gene differed by 13.0% between Groups A and B. In contrast to the sequence homogeneity of the Belgian isolates collected between 1991 and 1994, molecular diversity, which ranged between 0 and 2%, was observed among the Belgian isolates collected in 1995 and 1996. Among all Greek isolates the diversity ranged between 1 and 8%. However, this diversity does not seem to reflect geographical links between the outbreaks. A RT-PCR for the rapid and specific diagnosis of EMCV in a variety of clinical samples followed by nucleotide sequence analysis proved to be valuable for molecular epidemiological studies.

Ignorance is bliss? HIV and moral duties and legal duties to forewarn.

In 1997, a court in Cyprus jailed Pavlos Georgiou for fifteen months for knowingly infecting a British woman, Janet Pink, with HIV-1 through unprotected sexual intercourse. Pink met Georgiou in January 1994 whilst on holiday. She discovered that she had contracted the virus from him in October 1994 but continued the relationship until July 1996 when she developed AIDS. She returned to the UK for treatment and reported Georgiou to the Cypriot authorities. There have been a number of legal cases involving deliberate transmission of HIV, but most have involved forced exposure to infected bodily fluids for example, rape or biting, and have been dealt with using the existing legislation for rape or assault. While it is often difficult to prove responsibility for transmission in cases of forced exposure to HIV, it is even more contentious in cases like those of Janet Pink where an individual has consented to sex but claims that he/she was not forewarned of his/her partner's HIV-positive status. At present there is no specific criminal offence of having unprotected sexual intercourse without disclosing one's HIV-positive status but a prosecution could possibly be brought under any one of a number of existing offences. Perhaps a change of policy needs to be considered. The Home Office has issued a consultation document which outlines a proposal that will allow the criminalization of intentional transmission of diseases, like HIV, that are likely to cause serious harm. This revised legislation would cover all other potentially fatal diseases (including salmonella and legionnaire's disease, for instance) but seems primarily to be targeted at HIV transmission. Should transmission of HIV through consensual sex, without the HIV-positive status of the individual being disclosed, be an offence? This question, and that of whether there is a moral obligation to disclose a positive HIV status prior to having a sexual relationship is the subject of this paper.

Prevalence of multiple sclerosis in the region of Osona, Catalonia, northern Spain.

To ascertain the prevalence of multiple sclerosis in the region of Osona in Catalonia, northern Spain, an intensive study was undertaken in a small population of 72,000 people over a period of five years, using many sources of information. Patients were classified according to the Poser criteria. Most of the patients presented with mild symptoms only and many had not seen a neurologist or attended a large hospital. The prevalence of definite and probable multiple sclerosis was 58 per 100,000. This is nine to 10 times higher than had been found previously in Catalonia and is a similar prevalence to that found in southern Spain, in Sicily, and in Greek speaking Cyprus.

Selective isolation and distribution of the genus Planomonospora in soils.

For the screening of bioactive compounds and study of global distribution, a selective isolation method for Planomonospora strains by centrifugation from soil is examined. Planomonospora strains produced characteristic sporangia on the humic acid-trace salts gellan gum medium (pH 9.0) so that this genus was readily recognized on the isolation plate. High yields of motile spores were obtained by using a flooding solution containing 0.1% skim milk in 5 mM N-cyclohexyl-2-amino-ethanesulfonic acid (pH 9.0) followed by incubating the preparation at 32 degreesC for 90 min, centrifuging it at 1000 x g for 10 min, and further incubation at 32 degreesC for 60 min after centrifugation. By combining the techniques described above, we isolated 246 Planomonospora strains from 137 of the 1200 soil samples examined. Ninety-four percent of these strains were recovered from neutral to slightly alkaline soils (pH 7.0 to 9.0). Strains of P. venezuelensis group were obtained from 13 soil samples (1.1%), which were collected in Bolivia, Cyprus, Egypt, Greece, India, Japan, New Caledonia, and Turkey. Strains of this group appear widely distributed in the soil of tropical to temperate regions. To our knowledge, this is the first record that strains of this group have been isolated from a location other than Venezuela.

Impact of thalassemia major on patients and their families.

OBJECTIVE: To describe the burden of thalassemia major and its treatment, in terms of prevalence of iron-overload-related complications, direct and indirect costs, and the patient's physical and social well-being. METHODS: From October 1999 to May 2000 a survey of patients with thalassemia major was conducted in ten countries: Cyprus, Egypt, Greece, Hong Kong, India, Iran, Italy, Jordan, Taiwan, and the United States. RESULTS: 1,888 questionnaires (65%) were returned. The responses suggest that nowadays patients begin blood transfusions, and most use desferrioxamine (84.8%), but iron-related complications, including life-threatening ones such as heart disease, are still common. CONCLUSIONS: There remains a need to improve the management of thalassemia, as many patients with iron-related complications experience physical and social limitations.

Gathered Mediterranean food plants--ethnobotanical investigations and historical development.

The diversity of local Mediterranean food elements is not known in detail, but offers itself to search for new vegetables, salads, fruits and spices which could be used in to enrich diets outside their region of origin. Most amid those interesting local elements are edible wild plants and weeds. Ethnobotanical research has identified ca. 2,300 different plant and fungi taxa, which are gathered and consumed in the Mediterranean. Among these, >1,000 are only consumed in one single zone, therefore are strictly local. The percentage of local gathered food plant (GFP) taxa (present in <5 samples), is higher in the main centers of diversity at the periphery of the Mediterranean (Sahara, Alps, Caucasus, Canary Islands, the Levant). Islands (Sicily, Sardinia, Crete, Cyprus) also show a high proportion. Endemism of GFP taxa only accounts for a limited number of these 'ethnobotanical endemics' (only ca. 350 are endemic/ endangered species). On the other hand, only a few taxa--30 occurring in >20 samples--are consumed in most of the Mediterranean. Most have been analyzed in the Local Food- Nutraceuticals project. The ca. 800 GFP taxa that occur in more than the 5% of localities show a geographical pattern that permits one to recognize seven geographical groups. These groups show relationships with types of Mediterranean diet and could also be related with human genetic polymorphism through long-term co-evolution in a geographical mosaic pattern.

Randomized evaluation of the single-use SoftSeal and the re-useable LMA Classic laryngeal mask.

A number of laryngeal masks are available, including both re-usable and single-use masks. Single-use laryngeal masks may decrease the risk of transmitting prion infections. We performed a single-blind randomized trial in 200 spontaneously breathing female patients under general anaesthesia with nitrous oxide, to compare a new single-use laryngeal mask, the SoftSeal (Portex Ltd, U.K.), with a re-usable laryngeal mask, the LMA Classic (Laryngeal Mask Company Ltd., Cyprus). The primary outcome was successful insertion at the first attempt. Size 4 single-use (n = 99) or re-usable (n = 100) laryngeal masks, inserted by experienced anaesthetists, were equivalent for successful placement at the first attempt (90% versus 91% respectively). The single-use mask was less easy to insert (47% difficult versus 9%, P < 0.001). Clinical and anatomical tests of position and function were similar. The cuff pressure of the re-usable mask increased significantly compared with the single-use mask (median +10 cm versus -2 cm H2O, P < 0.001). Forty per cent of patients allocated the single-use mask and 20% of those allocated the re-usable mask experienced sore throat at 24 hours postoperatively (P < 0.05). An estimation of cost per patient use was greater for the re-usable mask. We conclude that the SoftSeal single-use laryngeal mask and the LMA Classic re-usable laryngeal mask airway are of similar clinical utility in terms of successful insertion and airway maintenance. The re-usable laryngeal mask was easier to insert and associated with less postoperative sore throat, but costs were higher.

An international survey of patients with thalassemia major and their views about sustaining life-long desferrioxamine use.

BACKGROUND: Management of thalassemia major requires patients to have life-long access to a treatment regimen of regular blood transfusions coupled with iron chelation therapy. The objective of this study was to investigate patients' reasons for missing iron chelation therapy with desferrioxamine, and the support to sustain life-long adherence to treatment. METHODS: From October 1999 to May 2000 a survey of patients with thalassemia major was conducted in ten countries: Cyprus, Egypt, Greece, Hong Kong, India, Iran, Italy, Jordan, Taiwan, and the United States. RESULTS: 1,888 questionnaires (65%) were returned. Most patients (1,573) used desferrioxamine, and 79% administered a dose at least 4 days a week. Inaccessibility of the drug was a common reason for missing a dose in India (51%), and in Iran (25%), whereas, in any other country, it was a reason for less than 17% of patients. Overall, 58% reported reasons for missing a dose related to their beliefs or feelings about the medication, and 42% drug-related side effects. CONCLUSION: Many patients miss doses of desferrioxamine and an opportunity remains to develop interventions that provide more support to sustain use of desferrioxamine.

Circum-Mediterranean cultural heritage and medicinal plant uses in traditional animal healthcare: a field survey in eight selected areas within the RUBIA project.

During the years 2003-2005, a comparative ethnobotanical field survey was conducted on remedies used in traditional animal healthcare in eight Mediterranean areas. The study sites were selected within the EU-funded RUBIA project, and were as follows: the upper Kelmend Province of Albania; the Capannori area in Eastern Tuscany and the Bagnocavallo area of Romagna, Italy; Cercle de Ouezanne, Morocco; Sierra de Aracena y Picos de Aroche Natural Park in the province of Huelva, Spain; the St. Catherine area of the Sinai Peninsula, Egypt; Eastern and Western Crete, Greece; the Paphos and Larnaca areas of Cyprus; and the Mitidja area of Algeria.One hundred and thirty-six veterinary preparations and 110 plant taxa were recorded in the survey, with Asteraceae and Lamiaceae being the most quoted botanical families. For certain plant species the survey uncovered veterinary phytotherapeutical indications that were very uncommon, and to our knowledge never recorded before. These include Anabasis articulata (Chenopodiaceae), Cardopatium corymbosum (Asteraceae), Lilium martagon (Liliaceae), Dorycnium rectum (Fabaceae), Oenanthe pimpinelloides (Apiaceae), Origanum floribundum (Lamiaceae), Tuberaria lignosa (Cistaceae), and Dittrichia graveolens (Asteraceae). These phytotherapeutical indications are briefly discussed in this report, taking into account modern phytopharmacology and phytochemistry.The percentage of overall botanical veterinary taxa recorded in all the study areas was extremely low (8%), however when all taxa belonging to the same botanical genus are considered, this portion increases to 17%. Nevertheless, very few plant uses were found to be part of a presumed "Mediterranean" cultural heritage in veterinary practices, which raises critical questions about the concept of Mediterraneanism in ethnobotany and suggests that further discussion is required.Nearly the half of the recorded veterinary plant uses for mammals uncovered in this survey have also been recorded in the same areas in human folk medicine, suggesting a strong link between human and veterinary medical practices, and perhaps also suggesting the adaptive origins of a few medical practices. Since most of the recorded data concern remedies for treating cattle, sheep, goats, and camels, it would be interesting to test a few of the recorded phytotherapeuticals in the future, to see if they are indeed able to improve animal healthcare in breeding environments, or to raise the quality of dairy and meat products in the absence of classical, industrial, veterinary pharmaceuticals.

The prevalence of multiple sclerosis in the Sanitary District of Vélez-Málaga, southern Spain.

Since little is known about the prevalence of multiple sclerosis (MS) in Spain, we undertook an epidemiologic study to ascertain the prevalence of MS in the Sanitary District of Vélez-Málaga, close to the city of Málaga, in southern Spain. The crude prevalence rate of MS in Vélez-Málaga was 53 per 100,000, twice as high as the prevalence previously reported in both the city and province of Málaga. The MS prevalence in the Sanitary District of Vélez-Málaga is similar to that in Sicily and in Cyprus.

Standardized visual evoked potentials for telematic electrodiagnosis from five laboratories in three European countries.

The pattern-reversal visual evoked potential (PR VEP) is an electrodiagnostic test which uses an alternating checkerboard pattern as the visual stimulus. To validate the performance of an automated testing system, the equipment was installed in five locations in three countries (the UK, Greece and Cyprus). PR VEPs require accurate control of stimulus size, luminance, contrast, timing, multichannel recordings and various modes of signal processing. Recordings were obtained from 70 subjects, 18-34 years old (seven male and seven female in each laboratory). The data were transmitted by telephone line to the central station in Bristol. Only in Bristol were the operators experienced. There were no significant differences between laboratories in latency or amplitude of the N70 and P100 components. There were no significant differences between eyes. There were significant differences between the sexes but this was related to head size. Decreased square size used in stimulation produced an increased latency in both components. The amplitude of the N70 component increased while that of the P100 decreased with reduced square size. The results confirmed the ability of the automated system to produce standardized PR VEP recordings comparable to those obtainable in advanced laboratories. The system performed well in different locations using inexperienced operators. The system is suitable for multicentre research studies and telemedicine.

Alcohol culture, family structure and adolescent alcohol use: multilevel modeling of frequency of heavy drinking among 15-16 year old students in 11 European countries.

OBJECTIVE: Frequency of heavy alcohol use among adolescents is examined by family structure and propensity toward heavy alcohol use on the individual level, and by alcohol availability and drinking patterns among adolescents on the societal level. The analysis includes direct effects and moderating effects of societal-level indicators on individual-level associations between family structure and frequency of heavy alcohol use. METHOD: The study drew upon self-reports from 34,001 students in Cyprus, France, Hungary, Iceland, Ireland, Lithuania, Malta, the Slovak Republic, Slovenia, Sweden and the United Kingdom participating in the 1999 European School Survey Project on Alcohol and Other Drugs study. Distinctions were drawn between adolescents living with both parents, a single mother, a single father, a mother and stepfather, a father and stepmother, and neither biological parent. The multilevel analysis estimated the effects of societal-level factors on the intercepts and slopes of individual-level regression models. RESULTS: Adolescents living with both biological parents engaged less frequently in heavy alcohol use than those living in any other arrangements. Living with a single mother was associated with less heavy drinking than living with a single father or with neither biological parent. National beer sales figures and societal patterns of heavy adolescent alcohol use predicted more frequent heavy drinking and greater effects of living in nonintact families. CONCLUSIONS: Adolescent heavy drinking is more common in all types of nonintact families. The adverse effect of living in nonintact families is greater in societies where alcohol availability is greater and where adolescents drink more heavily.
