New DXA Diagnostic Indexes of Abdominal Obesity.

: Cushing's syndrome (CS) is associated with weight gain and extreme central, visceral, abdominal obesity which is confirmed with dual-energy X-rays absorptiometric (DXA) diagnostic cut-off point (CP) values of central obesity indexes (COI), determined as an android to gynoid tissue and fat mass ratios. These best differentiate CS from non-CS obese women matched with CS according to their age and BMI. The aim of this study was to determine the CP values of new DXA indexes of central, abdominal obesity as a ratio of android and trunk to legs as well as trunk and legs to total tissue and fat mass that best differentiate CS and matched non-CS obese women in order to confirm central abdominal obesity, and to determine their normal CP values that best differentiate healthy non-obese women from CS and non-CS obese women, and to exclude abdominal obesity completely.

Genetic polymorphism of blood groups and erythrocytes enzymes in population groups of the Republic of Macedonia.

This study presents the results of an examination of 3 blood-group systems (ABO, Rhesus, and P1) and erythrocyte enzymes (ADA, AK, ALADH, PGD, SAHH, PGM1, PGM3, GPT, GOT, ACP, UMPK, ESD and GLO) in populations that reside in R. Macedonia. Four population samples from the Republic of Macedonia (129 Macedonians from Skopje, 98 Albanians from Skopje, 95 Aromanians from Krusevo, 102 Aromanians from Stip) were included in the study.

Population genetics of 15 AmpflSTR Identifiler loci in Macedonians and Macedonian Romani (Gypsy).

Allele frequencies of 15 AmpFlSTR Identifiler STR loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA) were analysed in a sample of 100 unrelated autochthonous Macedonian and 102 Macedonian Romani individuals, representing different ethnic groups residing within the same country of Former Yugoslav Republic of Macedonia. The interpopulation comparisons between Macedonians and Macedonian Romani with four south eastern European populations, Kosovo Albanians, Serbians from Vojvodina Province, western Romanians and northern Greeks were performed as well as comparison between Macedonian Romani and Assam population from Asia (India). Reported data point that Macedonian Romani, as an example of an endogamous population of Asian (Indian) origin, show significant allelic differences when compared to neighbouring south eastern European populations.

Paternal and maternal lineages in the Balkans show a homogeneous landscape over linguistic barriers, except for the isolated Aromuns.

The Balkan Peninsula is a complex cultural mosaic comprising populations speaking languages from several branches of the Indo-European family and Altaic, as well as culturally-defined minorities such as the Aromuns who speak a Romance language. The current cultural and linguistic landscape is a palimpsest in which different peoples have contributed their cultures in a historical succession. We have sought to find any evidence of genetic stratification related to those cultural layers by typing both mtDNA and Y chromosomes, in Albanians, Romanians, Macedonians, Greeks, and five Aromun populations.

Dermatoglyphic studies in eastern and south-eastern Europe.

In nine population samples from Bulgaria, Croatia, Greece, Hungary, Republic of Macedonia (Skopje and Aromuns from Stip region), Romania, Serbia and Slovakia 12 dermatoglyphic variables have been studied. There are distinct differences between the populations and between males and females. The Macedonian Aromuns are clearly separated from the other populations.

Population genetics of 8 Y chromosome STR loci in Macedonians and Macedonian Romani (Gypsy).

Eight Y chromosome short tandem repeat (STR) polymorphisms (DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393) were analyzed in Macedonians (n = 84) and Macedonian Romani ethnic group (n = 68). Observed allelic frequency distribution and locus diversity values in Macedonians correspond closer to neighboring southeastern European populations than (mostly) western European populations, whereas observed allelic frequency distribution and locus diversity values in Macedonian Romani, as expected based on their Asian (Indian) origin, differ from both neighboring southeastern and (mostly) western European populations. Sixty-six (78.

Allele frequencies of D21S11, FGA, TH01, and VWA in populations of the Balkans.

This study is part of an extensive investigation of the genetic relationship between Balkan populations, especially the Aromuns. Allele frequencies of four STRs (D21S11, FGA, TH01, VWA) from Macedonians (Skopje), Gramostian Aromuns from the Stip region (Macedonia), Moskopolian Aromuns from Krusevo (Macedonia), and Musequiar Aromuns from Dukasi (Albania) are presented.

High-resolution phylogenetic analysis of southeastern Europe traces major episodes of paternal gene flow among Slavic populations.

The extent and nature of southeastern Europe (SEE) paternal genetic contribution to the European genetic landscape were explored based on a high-resolution Y chromosome analysis involving 681 males from seven populations in the region. Paternal lineages present in SEE were compared with previously published data from 81 western Eurasian populations and 5,017 Y chromosome samples. The finding that five major haplogroups (E3b1, I1b* (xM26), J2, R1a, and R1b) comprise more than 70% of SEE total genetic variation is consistent with the typical European Y chromosome gene pool.

Phenotype and allele frequencies of some serum protein polymorphisms in populations of the Balkans.

Within a study of the genetics of Southeastern European populations seven serum protein polymorphisms (AMY2, BF, C3, CP, GC, HPA, TF) were examined in two samples of Aromuns and one reference sample (Musequiar-Aromuns from Dukasi in Albania, Moskopolian-Aromuns from Krusevo, Republic of Macedonia, and Macedonians from Skopje). The neighbor joining tree as well as the principal component analysis show results which do not correspond well to the geographic and historic background. This indicates that in the present case the serum protein polymorphisms give no clearly defined information about the relationships between the Balkan populations and to the origin of Aromuns.

Frequencies of mtDNA haplogroups in southeastern Europe--Croatians, Bosnians and Herzegovinians, Serbians, Macedonians and Macedonian Romani.

Mitochondrial DNA polymorphisms were analyzed in of 1,610 randomly chosen adult men from 11 different regions from southeastern Europe (Croatians, Bosnians and Herzegovinians, Serbians, Macedonians and Macedonian Romani). MtDNA HVS-I region together with RFLP sites diagnostic for main Euroasian and African mtDNA haplogroups were typed to determine haplogroup frequency distribution. The most frequent haplogroup in studied populations was H with the exception of Macedonian Romani among whom the most frequent were South Asian (Indian) specific variants of haplogroup M.

Alu insertion polymorphisms in the Balkans and the origins of the Aromuns.

We have analysed 11 human-specific Alu insertion polymorphisms in the Balkans to elucidate the origins of the Aromuns, a linguistic isolate inhabiting scattered areas in the Balkan Peninsula. Four Aromun samples (two from the Republic of Macedonia, one from Albania, and one from Romania) and five neighbouring populations (Macedonians, Albanians, Romanians, Greeks, and Turks) were analysed by means of genetic distances, principal components and analyses of the molecular variance (AMOVA). Three hypotheses were tested: Aromuns are Romanophonic Greeks; the result of a Romanian southward migration; or local descendants of the Thracians.

Genetic studies in south Balkan populations.

Within a study of the genetics of Balkan populations, four DNA-STR systems and 19 classical markers were examined in seven samples: Romanians (two groups), Albanians, Greeks and Aromuns (three groups). The results for the DNA-STR systems have been compared with data from the literature. The results show four clear separated groups: sub-Saharan black populations, North-African, Japanese and European populations.

Population genetic studies in the Balkans. II. DNA-STR-systems.

Within a study of the genetics of Southeastern European populations four DNA-STR-systems (D21S11, FGA, TH01, VWA) were examined in seven samples (samples of three Aromuns and four other Balkan populations). The results have been compared to data from four samples from literature (Austrians, Germans, Hungarians, Slovenians). The results show three clusters: a) the Aromuns from Albania (Andon Poci) and Macedonia (Stip region), b) the Romanian Aromuns (Kogalniceanu), Romanians (Constanta, Ploiesti) and Albanians (Tirana) und c) the data from literature.

Population genetic studies in the Balkans. I. Serum proteins.

Within a study of the genetics of Southeastern European populations seven serum protein polymorphisms (AMY2, BF, C3, CP, GC, HPA, TF) were examined in three samples of Aromuns (Albania: the village of Andon Poci, province Gjirocaster, Republic of Macedonia: Stip region, Romania: the village Kogalniceanu, province Dobruja) and four reference samples (Albanians: Tirana, Romanians: Constanta and Ploiesti as well as Greeks (Northeastern Greece)). The Aromun samples from Albania and Romania form one separate cluster and the reference samples together with the Aromuns from Macedonia (Stip region) form a second one.

Isonymy, consanguinity and repeated pairs of surnames in Aromun populations.

The Aromuns represent a small and almost unknown people that live scattered over the Balkan Peninsula. Due to their language, that is very similar to classical Latin, they are in a special position. The Aromuns settled only in more recent times.
