Organic mood disorder associated with the HAIR-AN syndrome.

The HAIR-AN syndrome is characterized by hyperandrogenism, insulin resistance, and acanthosis nigricans. The authors report the first case of an organic mood disorder associated with this condition that improved markedly in response to ovarian suppression with oral contraceptives. The proposed pathophysiology of this syndrome is also discussed.

The changing nationality composition of the Central Asian and Transcaucasian states.

Patterns and levels of migration in eight states located in the southern region of the former Soviet Union are analyzed for the period from 1989 to the beginning of 1996. "The focus of the paper is on the composition of migration streams by nationality and the impact that migration has had on the changing population of the newly independent states formed after the dissolution of the former Soviet Union. Recent data are tabulated and estimates discussed in detail disclosing the exodus of Russians and movement of other nationalities in each of the Transcaucasian (Armenia, Azerbaijan, and Georgia) and Central Asian (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan) countries."

Tropilaelaps mercedesae: an emerging global threat to apiculture - a comprehensive review.

Honey bees (Apis spp.) are key pollinators in agricultural and natural ecosystems; however, their populations are declining due to multiple interacting stressors and their synergistic effects, including parasitic mites. While Varroa destructor is widely recognized as the primary global driver of colony losses, mites of the genus Tropilaelaps, particularly Tropilaelaps mercedesae, are emerging as a serious and still underestimated threat. Native to Asia and naturally associated with wild hosts such as Apis dorsata, T. mercedesae has successfully transitioned to managed Apis mellifera colonies and is now widespread across much of Asia. Recent reports from Central Asia and the Caucasus and western Eurasian regions (including Georgia and Russia) indicate that this species is undergoing an ongoing westward expansion toward Europe. Its biological traits-including an extremely short reproductive cycle, obligate dependence on sealed brood, high dispersal capacity, and the potential to transmit viruses such as deformed wing virus (DWV)-facilitate rapid population growth and severe colony-level damage, particularly in A. mellifera, which lacks effective behavioral defenses against this mite. This review synthesizes current knowledge on the taxonomy, morphology, life cycle, host-parasite interactions, geographic distribution, and spread of Tropilaelaps mites, with emphasis on T. mercedesae. It also evaluates available diagnostic approaches, including brood-based methods, adult bee-based methods, and natural mite-fall techniques. Furthermore, evidence on chemical and biotechnical control strategies is summarized, and their strengths, limitations, and integration within an Integrated Pest Management (IPM) framework are discussed. Overall, current findings highlight the urgent need to strengthen surveillance, standardize diagnostic protocols, and develop sustainable control strategies to prevent the global spread of Tropilaelaps mites.

[Genetics of Caucasian population: distribution of various immunological and biochemical markers in western Georgia].

The distribution of genetic markers of blood groups (ABO, Rhesus, MNSs, P, Duffy, Kell-Cellano), plasma proteins (Hp, Gc, Tf, C'3) and red-cell enzymes (AcP, EstD, GLO-1), and also ABH secretion among 10 populations of Western Georgia has been studied. The common characteristic of distribution of gene frequencies for the markers studied was obtained as a whole in Georgia. The Georgians were compared for these markers with some populations of the Caucasus, Europe and West Asia. Among Caucasian populations, Georgians are most similar to Abkhasians. According to some systems, Georgians are close to European groups (ABO, Dubby, GLO-1, EstD), while they are similar to West-Asian groups, as judged by other systems (ABH secretion, AcP). According to Rhesus and MNSs systems, Georgians differ both from populations of Europe and from populations of West Asia.

Earliest Pleistocene hominid cranial remains from Dmanisi, Republic of Georgia: taxonomy, geological setting, and age.

Archaeological excavations at the site of Dmanisi in the Republic of Georgia have uncovered two partial early Pleistocene hominid crania. The new fossils consist of a relatively complete cranium and a second relatively complete calvaria from the same site and stratigraphic unit that yielded a hominid mandible in 1991. In contrast with the uncertain taxonomic affinity of the mandible, the new fossils are comparable in size and morphology with Homo ergaster from Koobi Fora, Kenya. Paleontological, archaeological, geochronological, and paleomagnetic data from Dmanisi all indicate an earliest Pleistocene age of about 1.7 million years ago, supporting correlation of the new specimens with the Koobi Fora fossils. The Dmanisi fossils, in contrast with Pleistocene hominids from Western Europe and Eastern Asia, show clear African affinity and may represent the species that first migrated out of Africa.

A more diversified America: state and local population changes, 1990-1997.

Recently, the U.S. Bureau of the Census released state and county population estimates with age, gender, race and Hispanic origin detail for 1990-1997. These estimates illustrate the changing demographics of the United States. The 1997 state population estimates show that both Texas and Georgia experienced notable population growth since 1990. Texas replaced New York as the second largest state; Georgia bumped North Carolina from the list of top 10 most populous states to become the state with the 10th largest population. In both Texas and Georgia, migration flows have contributed to the population change. Texas is one of the most popular "intended states of residence" for international migrants, many coming from Latin American countries. On the other hand, Georgia's growth has largely been influenced by "rustbelt" to "sunbelt" domestic migration. At the county level, the largest total population increases again occurred in western and southern states. Population estimates for Asian and Pacific Islanders show that this population remained concentrated in the West in 1997. Similarly, the Hispanic population is primarily concentrated in southwestern states. However, as the Asian and Pacific Islander and Hispanic populations continue to grow, there is spillover into other regions, primarily the larger metropolitan areas in the South, including Washington, DC, and Atlanta, GA. The population projections produced by the Census Bureau indicate that racial and ethnic diversity will continue to increase in the United States well into the next century.

Primate T-lymphotropic virus type I LTR sequence variation and its phylogenetic analysis: compatibility with an African origin of PTLV-I.

Due to the low evolutionary rate and the limited horizontal transmission of human T-lymphotrophic virus type I (HTLV-I), its phylogenetic analysis reveals the movements and contacts of ancient populations. Since simian strains cannot be distinguished from human strains by phylogenetic criteria, this virus has appropriately been called primate T-lymphotropic virus type I (PTLV-I). We sequenced the LTR of six PTLV-I strains: three HTLV-I strains from African patients with tropical spastic paraparesis (TSP) (Equateur, Zaire), two laboratory HTLV-I strains of Japanese origin, MT-2 and MT-4, and one STLV-I from a baboon of the primate center in Sukhumi, Georgia. We applied four phylogenetic inference methods: neighbor-joining (NJ), unweighted pair group method using arithmetic averages (UPGMA), Fitch and Wagner parsimony (pars), and maximum likelihood (ML), to these 6 LTR sequences and 18 published LTR sequences (cosmopolitan, African, and Melanesian HTLV-I strains and African and Asian STLV-I strains). Three major HTLV-I subtypes can be identified with all four methods: the cosmopolitan HTLV-Ia, the central African HTLV-Ib, clearly descendant from a STLV-I CH-like African ancestral simian strain, and the Melanesian HTLV-Ic, probably descendant from an Asian STLV-I strain. We observe a segregation of PTLV-I sequences according to their geographical origin and not according to host species. The Zairean strains form a cluster closely related to an STLV-I strain isolated from a chimpanzee (STLV-I CH) and distinct from western African strains, which belong to the cosmopolitan subtype of HTLV-I. The Sukhumi STLV-I strain found in a captive-born baboon was of Asian descent. We experienced rooting problems with UPGMA when using HTLV-II as an outgroup. Concordant results with all four methods were obtained by eliminating HTLV-II LTR sequence fragments with bad alignment to HTLV-I. This resulted in a HTLV-II root node on the African STLV-I TAN90 terminal branch (with bootstrap values above 92% for the NJ and pars methods) and not on the Asian STLV-I PtM3 branch, as has been derived by others based on their use of UPGMA. The results of the analyses also support a higher evolutionary rate of PTLV-I in Asia, implying that the trees obtained with the NJ and ML methods have a higher reliability. These results are more compatible with an ancient African origin of PTLV-I than with an Asian origin.
