Intersecting Jones projections
Let M be a von Neumann algebra on a Hilbert space H with a cyclic and
separating unit vector \Omega and let \omega be the faithful normal state on M
given by \omega(\cdot)=(\Omega,\cdot\Omega). Moreover, let {N_i :i\in I} be a
family of von Neumann subalgebras of M with faithful normal conditional
expectations E_i of M onto N_i satisfying \omega=\omega\circ E_i for all i\in I
and let N=\bigcap_{i\in I} N_i. We show that the projections e_i, e of H onto
the closed subspaces \bar{N_i\Omega} and \bar{N\Omega} respectively satisfy
e=\bigwedge_{i\in I}e_i.This proves a conjecture of V.F.R. Jones and F. Xu in
\cite{JonesXu04}

Услуги здравоохранения, дружественные к молодежи через призму стандартов качества
IMSP Institutul Mamei şi CopiluluiBackground: The Youth Friendly Health Services in Moldova (YFHS) are focused on real needs and age peculiarities particularities of adolescents and teenagers in their health and development priority interest, from medical and
psycho-social positions. YFHS are contribute significantly to solve the priority health issues of young people: STI/HIV/
AIDS, unwanted pregnancy, mental health problems as a result of substance abuse, psychological and emotional disturbances of personality, health problems as a result of violence, disturbances of nutrition, particularly malnutrition,
developmental disorders during puberty.
Records provided by the WHO shows that access to quality health services for young people with a holistic approach offered according to the standards of youthfriendly health services, is one of the major factors for the protection
of young people across health issues, including sexual and reproductive health.
Aim of the study: Evaluation of quality of the youth-friendly health services according to the quality standards of
YFHS in Moldova at the beginning of their implementation.
Materials and methods. Following instruments were used for the study: 1-questionnaire for young beneficiaries
of YFHC, 2-questionnaire for young people in the community (service coverage tool), 3 - questionnaire for manager of
YFHC, 4- questionnaire for providers of YFHS, 5 - observation sheet of providing YFHS.
Result. The beneficiary of YFHS is most commonly a teenager aged 15-19 years, who is a school boy/girl or a
student, most commonly a girl, a boy rarely, mostly unmarried; the beneficiary of reproductive health offers (RHO)
is in absolute majority of cases is a girl aged between 19 and 24 years, more often married or divorced. About 37% of
the specialists included in the study did not receive training in YFHS, adolescent health and development. At the initial
stage of implementation of quality standards, the evaluated institutions meet these standards in about 57%, ranging
from 49% to60% in YFHS and RHO.
Conclusions: The study showed the portraits of the beneficiaries from the institutions that provide YFHS.To increase
the quality of services provided to the beneficiaries in the evaluated institutions, it is necessary to strengthen human
potential through training specialists of YFHS in adolescent health and development. To ensure sustainability of education is necessary to introduce topics related to adolescent health and development in undergraduate and postgraduate
curricula. At the initial stage of implementation of quality standards, the evaluated institutions meet these standards in
about 57%, ranging from 49% to 60% in YFHS and in reproductive health offices.Введение. Услуги здравоохранения дружественные к молодежи, в Молдове основаны на реальных потребностях здоровья и развития подростков и молодежи, учитывая их возрастные особенности, как с медицинской,
так и с психо-социальной позиции.

Trends in air temperature and atmospheric precipitation in Botoşani between 1961 and 2017
Air temperature and precipitations are major factors affecting the climate of a certain place. They define the basic matrix of the climate, and their evolution are of interest for the whole of both human and scientific community. The purpose of the present study is to highlight the sign and the magnitude of the trend in the air temperature at Botoşani city weather station for the whole period 1961-2017, and for both its major subdivisions (1961-1990 and 1991-2017, respectively) throughout different temporal subsets (from the level of an average year to the level of a month). Besides air temperature, we determined the evolutive trend in the amount of rainfall using a similar methodology (based mainly on the Mann- Kendall and t tests).Following our approach, we showcased the thermal and pluviometric reality at Botoşani, which is in a continuous change (as for the temperature values) or in a relatively dynamic balance (with respect to the amount of precipitations). More precisely, at Botoşani, against an annual average temperature of 9.4°C and an annual average of precipitations of 569.0 mm, after the year 1961 and mostly after 1990, the tendency was positive, which indicates an increase in air temperature. From a thermal point of view, considered annualy, seasonally and by warm and cold seasons (excepting autumn, with an insignificant increase), air temperature displayed a representative increase in value over the assessed period (1961-2017). On the whole, the annual temperature values increased by 0.32°C / decade, which presents a maximum statistical significance. Annual amount of rainfall increased over the period 1961 – 2017 by 4.46--5.35 mm/ decade, but this was not statistically significant.</p
Aplicarea metodelor invazive în diagnosticul prenatal: retrospectiva rezultatelor pe anii 2009-2011
Indentifi carea precoce a posibilelor riscuri în ceea ce privesc malformaţiile congenitale ale fătului, astăzi, a devenit un obicei comun în societăţile dezvoltate, iar necesitatea unui diagnostic prenatal veridic, creşte odată cu apariţia tendinţei de a avea copil la vârsta după 35 de ani. Din 1298 gravide incluse în studiu, care pe parcursul anilor 2009-2011 au fost supuse diagnosticului prenatal invaziv, în 28 cazuri au fost depistate aberaţii cromozomiale la făt. Totodată, în perioada respectivă, au fost depistaţi 202 nounăscuţi cu malformaţii congenitale, iar circa 70% copii cu sindromul Down s-au născut de la mame cu vârsta după 35 de ani. Respectarea cu stricteţe a prevederilor Ghidului Naţional de Perinatologie, unde este specificat că gravida după 35 de ani face parte din grupul de risc, ar reduce substanţial de numărul malformaţiilor congenitale depistate postnatal, cu toate că în curs de trei ani s-a atestat o creştere succesivă a solicitării diagnosticului prenatal invaziv
Пренатальная диагностика мышечной дистрофии и спинальной мышечной атрофии за последние 4 года и эффективности существующей методологии пренатальной диагностики в Республике Молдова
IMSP Institutul Mamei şi Copilului Centrul de Sănătate a Reproducerii şi Genetică MedicalăIntroduction. The severity of hereditary diseases is already well known throughout the world. The monitoring and
prevention of hereditary diseases are the current tasks of medical genetics and health. Prenatal diagnosis (PD) is one
of the methods proposed to prevent the birth of children with congenital malformations incorrigible, monogenic and
chromosomal pathologies. Muscular dystrophy Duchenne / Becker and spinal muscular atrophies are neuromuscular
hereditary X-linked and respectively autosomal recessive disorders and that are frequently encountered in Moldova and
can be detected through prenatal diagnosis.
Materials and methods. The research was held in the scientific department of the Centre for Reproductive Health and
Medical Genetics, Laboratory of Human Molecular Genetics. After medico-genetic consultation pregnant women who
are at risk of having a pregnancy affected by a hereditary disease, namely Duchenne and Becker muscular dystrophy
(DMD/B) and spinal muscular atrophy (SMA) undergo prenatal diagnosis (PD), which Moldova is achieved by methods
such as multiplex PCR, PCR / RFLP, the primer sets specific and polymorphic sites.
Purpose. The purpose of the work is to present data of prenatal diagnosis of neuromuscular disorders with high frequency
in Moldova during the last four years.
Results. In total were performed 14 prenatal diagnoses: 9 - DMD/B and 5 for SMA during 2011-2014. Making the
prenatal diagnosis of DMD/B and SMA has allowed the direct analysis of deletions or RFLP test and were detected 4
affected fetuses, 3 of them were with DMD / B and 1 with SMA. Have been analyzed the strategies for prenatal diagnosis
of these diseases in different countries and their methods.
Conclusions. Prenatal diagnosis is an important strategy and an effective way to prevent the birth of children with
hereditary monogenic diseases in families at risk. This strategy applies to all populations, but with different methodologies.
The methods of modern molecular genetic prenatal diagnosis raise the efficiency and precision to 98%. The efficiency of
prenatal diagnosis in Moldova is 71,4%. Analyzing different diagnostic methods used in the world was proposed as the
method which will be better implemented in Moldova.Введение. Тяжесть наследственных заболеваний хорошо известна во всем мире. Лечебно-диагностические
стратегии и методы анализируются и затем ставятся акценты в их развитии. Ключевой особенностью
является неравномерного их распределение. Мониторинг и предотвращение наследственных заболеваний
являются текущими задачами медицинской генетики. Пренатальная диагностика (ПД) является главным
методом предотвращения рождения детей с моногенной и хромосомной патологии. Миодистрофия Дюшенна
/ Беккера и спинальная мышечная атрофия являются наследственными нервно-мышечными болезнями,
которые часто встречаются в Р. Молдова и проведение ПД этих заболеваний возможно в нашей стране.
Материалы и методы. Исследования проводились в научном отделе Центра Репродуктивного Здоровья
и Медицинской Генетики, в лаборатории молекулярной генетики человека. После медико-генетического
консультирования беременных женщин с высоким риском наследственных болезней, а именно МДД/Б и СМА
проводится ПД. Мультиплексная ПЦР и анализ сцепления (ПЦР- ПДРФ) используются в Республике Молдова.
Цель. Анализ результатов пренатальной диагностики, проведенных за последние четыре года в Лаборатории
молекулярной генетики человека и оценка эффективности ПД в РМ.
Результаты. В течение 2011-2014г. было сделано 14 пренатальных диагностических тестов: 9ПД на
МДД/Б и 5 на СМА. Используя прямой поиск протяженных делеций методом МПЦР и анализ сцепления
(ПЦР- ПДРФ) позволило выявить 4 плода с наследственными болезнями: 3 плода с МДД/Б и одного c СМА.
Проанализировано стратегии и методы ПД, использующиеся в разных странах в настоящее время и проведен
анализ эффективности применения существующих методов ПД в РМ. Эффективность составляет 71,4%.
Выводы. Пренатальная диагностика является важной стратегией и эффективным способом предотвратить
рождение детей с наследственными моногенными заболеваниями. Стратегия ПД применяется во многих
популяциях, но с использованием различных методов. Применение молекулярно-генетических методов при
современной ПД повышает эффективность и точность до 98% по данным литературы, но эффективность
ПД в РМ составляет 71,4%. Предложены современные молекулярно-генетические методы ПД, которые
