Genitourethral infections caused by D–K serotypes ofChlamydia trachomatis
Authors: Holló Péter , Jókai Hajnalka , Herszényi Krisztina , Kárpáti Sarolta
Published: December 2014

Sexually transmitted infections of the urogenital tract are most commonly caused by the intracellular bacteria Chlamydia trachomatis worldwide, resulting the clinical picture of acute urethritis in men as well as urethritis and endocervicitis in women. As women often present with few symptoms only or a completely symptom-free disease course, one of the most important long-term complications is chronic pelvic inflammatory disease often followed by the development of infertility caused by chronic scar formation. Well-organized screening programs are considered to have a leading role in the prevention of disease spreading and long lasting unwanted complications. Antibiotic treatment options are often influenced by special circumstances, such as pregnancy and several complicated clinical forms. The aims of the authors are to give a concise review on the current knowledge regarding Chlamydia trachomatis infections and summarize typical clinical signs, modern diagnostic techniques as well as accepted treatment protocols and basic aspects of screening.

Authors: Wikonkál Norbert , Nagy Patrícia , Tóth Béla , Marschalkó Márta , Tislér András , Kárpáti Sarolta
Published: December 2014

The authors report the history of a patient with syphilitic glomerulonephritis, a rare complication of syphilis. The patient was admitted to the hospital with clinical symptoms of neurosyphilis. During his hospital stay urine analysis revealed an extremely high proteinuria, that had not been known before. Intravenous penicillin treatment improved the renal protein loss, but it took a total of six months until complete resolution was achieved. The serology that confirmed the syphilis, the concomitant nephrotic syndrome and the improvement after penicillin therapy met the criteria of syphilitic glomerulonephritis. This case prompted the authors to review the literature about this rare complication of syphilis that has a great clinical significance. Orv. Hetil., 2015, 156(1), 32–35.

Published: December 2014

Lymphogranuloma venereum is a sexually transmitted infection caused by the Chlamydia trachomatis serovars L1–3. It has been found to be endemic in tropical countries. In the last decades several cases have been reported in Western Europe, particularly in men who have sex with men population infected with human immunodeficiency virus. The authors present three cases of lymphogranuloma venereum infections, observed at their department in 2013 and 2014. The three human immunodeficiency virus infected patients who belonged to men who have sex with men population had casual sexual contacts in Western Europe. The symptoms included urethral discharge, discomfort and inguinal lymphadenomegaly in two patients, and rectal pain, discharge and perianal ulceration in one patient. The diagnosis was confirmed by nucleic acid amplification test performed in samples obtained from urethral discharge and exudate of perianal ulcer; lymphogranuloma venereum 2b serovars were demonstrated in two patients and serovar 2 in one patient. Doxycyclin (daily dose of two times 100 mg for 21 days) resolved the symptoms in all cases. The authors conclude that lymphogranuloma venereum is a diagnostic challenge in Hungary, too. It is important to be aware of the altered clinical features of this disease to prevent complications and spreading. Orv. Hetil., 2015, 156(1), 36–40.
Ocena stopnia zgodności wybranego modelu równowagi ogólnej z danymi empirycznymi
Authors: Wróbel-Rotter Renata
Published: December 2014

The paper presents the derivation of structural equations of an estimated general equilibrium model, illustrates techniques of its connection with the data observed and discusses a method of assessing the degree of acceptance by the data. The results suggest that the model is not confirmed by the data. Logarithms of the marginal data density tend to systematically decrease when the weight of the structural model is being increased in hybrid vector autoregression. This defines an econometric tool which can capture a general equilibrium model on the one hand and almost unrestricted vector autoregression on the other. As a consequence of high structural model misspecification, economic conclusions it leads one to draw may be highly inaccurate.

Clinical Efficacy of Subgingival Debridement With Adjunctive Erbium:Yttrium‐Aluminum‐Garnet Laser Treatment in Patients With Chronic Periodontitis: A Randomized Clinical Trial
Authors: Sanz‐Sánchez Ignacio , Ortiz‐Vigón Alberto , Matos Rita , Herrera David , Sanz Mariano
Published: December 2014

Background: The efficacy of erbium:yttrium‐aluminum‐garnet (Er:YAG) laser application as an adjunct to subgingival debridement in the treatment of chronic periodontitis (CP) is controversial. This study assesses the efficacy of combining full‐mouth subgingival debridement with Er:YAG laser application in the treatment of patients with CP.

Methods: In this 12‐month, single‐masked, parallel‐group clinical trial, 40 patients with moderate CP were selected and randomly assigned to a test group (one session of full‐mouth ultrasonic subgingival debridement followed 1 week later by Er:YAG application in sites with initial probing depths [PDs] of ≥4.5 mm) and a control group (two sessions of ultrasonic debridement within 1 week). The main outcome variable was change in PD; the secondary outcomes were change in clinical attachment level and proportion of sites with bleeding on probing. Outcomes were assessed at baseline and after 3, 6, and 12 months. Data were analyzed as intention to treat using analysis of variance to assess intergroup differences.

Results: Both treatments resulted in significant clinical improvements. The test group achieved, in comparison with the control, a significantly lower percentage of sites with PD ≥4.5 mm (17.44% versus 22.83%, respectively; P = 0.004) and a tendency for a lower percentage of sites with PD ≥4.5 mm and bleeding on probing (9.78% versus 12.69%; P = 0.052).

Conclusion: This limited added clinical effect may justify the use of a protocol combining full‐mouth ultrasonic debridement with laser therapy in the treatment of initial moderate CP.

Authors: Takai Hirokazu , Takahashi Tomoki , Takai Seiko , Nakane Nobutake
Published: December 2014

Case:

A sixty-five-year-old man with diabetes mellitus had bilateral calcaneal avulsion fracture without a history of trauma. Both fractures were treated surgically with modified tension-band wiring, cerclage wiring, and screws. Six months after the surgery on the left side, the patient had a left Achilles tendon rupture proximal to its insertion into the calcaneus.

Conclusion:

Calcaneal avulsion fractures are rare but often have complications. Even if these fractures are managed by well-established treatment methods, an unanticipated complication, namely a delayed Achilles tendon rupture, can occur in patients with diabetes.

Case:

After a fall, a seventy-seven-year-old woman had been treated at an outside institution with a right total elbow arthroplasty (TEA), which was complicated by subsequent infection and a periprosthetic fracture. After referral to our institution for definitive management, we confirmed chronic periprosthetic infection. The patient underwent a two-stage revision with interval use of a hinged antibiotic-loaded cement spacer created with Ilizarov rods. One year postrevision, she had no pain, no signs of infection, and an elbow active range of motion of 10° to 110°.

Conclusion:

A two-stage revision of an infected TEA with a periprosthetic fracture can be managed successfully with our novel hinged antibiotic-loaded cement spacer.
Ethiopathogenesis of Depressive Disorders
Authors: Pasquini M , Berardelli I , Biondi M
Published: December 2014

Etiology of depressive disorders is still unknown. Several factors are involved in its pathophysiology such as neurotransmitters and neuroendocrine alterations, genetics, life events and their appraisal. Some of these components are strictly linked. Subjects with a family member affected by mood disorders are more prone to suffer from depressive disorders. It is also true that receiving feedbacks of indifference or neglect during childhood from one parent who suffer from depression may represent a factor of vulnerability. Indeed, reaction to a specific negative event may determine an increased allostasis which lead to a depressive episode. Thus, a psychological cause does not exclude a neurobiological cascade. Whereas in other cases recurrent depressive episodes appear in absence of any negative life event. This review provides a set of data regarding the current etiopathogenesis models of depression, with a particular attention to the neurobiological correlates and vulnerability factors.

Published: December 2014

Attention-deficit/hyperactivity disorder (ADHD) is frequently associated with negative psychological outcomes. This study explores the relationship between self-esteem, ADHD symptoms and parental stress. It compares children with ADHD, children with epilepsy (E) and typical developmental controls (TD). Participants included 65 children (aged 9-12 yrs) and their parents. The assessment was conducted by Multidimensional Self-Concept Scale (MSCS), Parent Stress Index (PSI) and Conners' Parent Rating Scales–Revised. Significant differences were found in Social, Competence and Academic areas of self-esteem between children with ADHD, with E and TD. Moreover, parents of children with ADHD showed a higher overall stress than both other groups. In conclusion, it seems important to evaluate the psychological aspects of ADHD con-dition, both in children and in parents, in order to suggest an individual multimodal treatment.
Study on the Combined Performance of Fiber Reinforce Concrete Material
Authors: Siyi Zeng , Guoping Jiang , Sanxia Xiao
Published: December 2014

As concrete is a heterogeneous material. There is a combination of weak interface – interface in the concrete.
From the point of view of mechanics analysis, the interface exists in the combination of materials within the boundary [1].
For ordinary concrete, damage often occurs from the junction interface. The analysis of concrete materials and its stress
distribution near the interface has vital significance. In fact, the boundary condition on the interface, and mutual constraint
represent the deformation of the fiber and concrete. The constraints cause stress concentration of interface and nearby
interface geometry mutations where stress concentration is very serious. In the elastic range, the stress point at some point
tends to infinity, called a singularity. At the same time, due to material composition by multiphase materials, there are a
lot of micro cracks at the interfaces. The study of the interface crack model and the materials of the singularity has an
important means for the material’s performance.
A Study on the Effect of Elastic Deformation on the Performance of
Dynamic Pressure Oil Film Bearing of the Ships
Authors: Liu Chao , Li Fan-Chun
Published: December 2014

Dynamic pressure oil film bearing is an important mechanical component of the ship. With the development of
large-sized ships, their dynamic pressure oil films often run at high speed and under heavy load generating high oil film
pressure. In addition, due to the increased use of thin walled bearing shell with materials of low elastic modulus, the
elastic deformation of the bearing shell which is in dynamic pressure oil film bearing cannot be ignored. During
computation, if the effect of elastic deformation on the performance of dynamic pressure oil film bearing is ignored as is
usually the practice, the difference between the theoretical and the actual results will be enormous. Therefore, this article
has taken the effect of bearing shell's elastic deformation on bearing performance as the research target. A coupling
algorithm program in Matlab is written to simulate and solve the oil film bearing dynamic pressure lubrication theory,
considering elastic deformation of bearing shell in a way that is more aligned with the actual working conditions. A
comparison is conducted between the above results and the results with no consideration of elastic deformation and the
process and regularity of the effect of elastic deformation and other factors on the performance of oil film bearing shell in
operation under dynamic lubrication are analyzed. Therefore, more accurate theoretical basis can be provided for the
design and fault diagnosis of dynamic pressure oil film bearing of the ships.

Rub-Impact Rotor System
Authors: Luo Yuegang , Zhang Songhe , Wu Bin , Wang Wanlei
Published: December 2014

Based on the coupling model of nonlinear oil-film force and nonlinear seal fluid force, a nonlinear dynamic
model of rotor system with rub-impact fault is set up. The dynamic characteristics of the system were studied with
numerical simulation and the effects of airflow excited force, rubbing gap and stiffness parameters on movement
characteristics of the rotor were analyzed. The results indicate that the airflow excited force can significantly restrain the
stability and amplitude of rubbing rotor. The less rubbing gap and larger rubbing stiffness are in favor of the stability of
the system.

Published: December 2014

A kind of new hot strip steel temperature measuring device has been designed. The mathematical model and
the geometric model of the nozzle flow field have been established based on computational fluid dynamics theory. The
impact of equalizing groove and nozzle structure on the nozzle system characteristics is researched in detail using fluid
dynamics software FLUENT. The research results show that: the nozzle pressure groove can improve the gas flow
properties of the nozzle and the nozzle can meet the design requirements. The nozzle gap, the inlet pressure of nozzle, the
lower edge diameter of the nozzle, nozzle diameter and chamfer structure have different effects on flow field
characteristics and nozzle flow. The study provides a theoretical basis for designing hot strip steel temperature
measurement devices and the nozzle of purge.

Activity of acetate kinase in cell-free extracts and individual fractions and the kinetic properties of the enzyme obtained from theDesulfovibrio pigerVib-7 andDesulfomicrobiumsp. Rod-9 intestinal bacterial strains were presented at the first time. The highest activity of the enzyme was measured in the cell-free extracts (1.52 ± 0.163 and 0.46 ± 0.044 U × mg-1 protein forD. pigerVib-7 andDesulfomicrobiumsp. Rod-9, respectively) compared to other fractions. The specific activity of acetate kinase in the extracts of both bacterial strains was determined at different temperature and pH. Analysis of the kinetic properties of the purified acetate kinase was carried out. The acetate kinase activity, initial (instantaneous) reaction rate (V0) and maximum rate of the acetate kinase reaction (Vmax) inD. pigerVib-7 andDesulfomicrobiumsp. Rod-9 intestinal bacterial strains were defined. Michaelis constants (KmAcetyl phosphate and KmADP) of the enzyme reaction (2.54 ± 0.26 and 2.39 ± 0.24 mM forD. pigerVib-7 as well as 2.68 ± 0.25 and 2.47 ± 0.27 mM forDesulfomicrobiumsp. Rod-9, respectively) were calculated. The described results of acetate kinase, an important enzyme in the process of organic compounds oxidation and dissimilatory sulfate reduction would be perspective and useful for clarification of the etiological role of these bacteria in the development of inflammatory bowel diseases in humans and animals.

Authors: F.E Abourazzak , N Kadi , H Azzouzi , F Lazrak , A Najdi , C Nejjari , T Harzy
Published: December 2014

Objectives :

To compare foot posture in people with and without medial compartment knee osteoarthritis (OA), and to assess association between its abnormalities and medial compartment knee OA.

Methods :

We compared the foot posture of patients with clinically and radiographically-confirmed medial compartment knee OA and asymptomatic healthy controls using the foot posture index (FPI), navicular height, and the medial arch.

Results :

We included 100 patients and 80 asymptomatic controls. The mean age of patients was 59 ± 7 (44-76) years and 48 ± 9 (28-60) years in the control (p=0.06). Patients group have more pronated foot for FPI (1.50 ± 2.68 vs 0.72 ± 2.63; p=0.05), more flat foot (42% vs 22%; p=0.03), and less pes cavus than the control group (58% vs 77%; p=0.004). However, there was no significant difference between the groups in the navicular height (3.90 ± 0.85 cm vs 4.00 ± 0.76 cm; p=0.41).

In multivariate statistical analysis, after adjusting for age and body mass index, pronated foot in FPI (OR=1.22, 95%IC= [1.06-1.40], p=0.005), and pes cavus (OR=0.32, 95%IC= [0.11-0.93], p=0.03) had a significant correlation with the knee osteoarthritis.

Conclusion :

Pronated foot posture and flat foot are significantly associated with medial compartment knee osteoarthritis.

Authors: Wergifosse Isabelle de , Westhovens Rene
Published: December 2014

A young woman presents with severe polyarticular osteoarthritis with relevant family history potentially suggesting a hereditary disease. Previously, the patient’s mother had been diagnosed with rheumatoid arthritis and reported to have suffered from some locomotor problems. Careful clinical evaluation with an extensive personal and familial history pointed towards a diagnosis of Stickler syndrome, an autosomal dominant condition with progressive arthro-ophthalmopathy, (early osteoarthritis and myopia). Following this timely diagnosis, genetic counselling was offered.
Sjögren’s, Renal Tubular Acidosis And Osteomalacia - An Asian Indian Series
Authors: Sandhya Pulukool , Danda Debashish , Rajaratnam Simon , Thomas Nihal
Published: December 2014

Objective:

To study the profile of Renal Tubular Acidosis (RTA) in Asian Indian patients with Primary Sjögren's Syndrome (pSS).

Methods:

The Electronic medical records of patients with a diagnosis of pSS seen between 2003 and 2010 at our tertiary care teaching hospital were screened for RTA. Clinical features, immunological profile, acid-base balance and electrolyte status, 25-hydroxyvitamin D (25(OH) D3) levels, histopathological changes in minor salivary gland biopsy samples and radiological findings were retrieved. RTA was diagnosed in cases of hyperchloremic metabolic acidosis with urinary pH values higher than 5.5. Those with known features suggestive of RTA including hypokalemic paralysis, hyperchloremia and nephrocalcinosis without acidosis were defined as incomplete RTA.

Results:

Of the 380 patients with clinically suspected pSS, 25 had RTA. The median age was 32 (18-60) years. Nineteen patients had complete RTA. Six had incomplete RTA. Only 10 patients (40%) had symptoms related to RTA at presentation. Sixteen patients (64%) had present or past history of hypokalemic paralysis. Pseudofractures were seen in 7 patients and an additional 2 had subclinical radiological osteomalacia. Majority of the patients (61.2%) had a normal 25(OH) D3 level. Those with osteomalacia had significantly lower serum phosphate, blood ph and higher alkaline phosphatase. Serum calcium and 25(OH) D3 levels were not significantly different between patients with osteomalacia and those without.

Conclusion:

Most patients were asymptomatic for RTA inspite of clinically overt and elicitable features. Skeletal manifestation was a common finding in patients with Sjögren and RTA, despite normal levels of 25 (OH) D3 in a majority.
Monitoring Complete Blood Counts and Haemoglobin Levels in Osteoarthritis Patients: Results from a European Survey Investigating Primary Care Physician Behaviours and Understanding
Authors: Walker Chris , Faustino Augusto , Lanas Angel
Published: December 2014

Background:

Chronic use of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with an increased risk of gastrointestinal (GI) toxicity, including occult blood loss and the development of clinically significant anaemia.

Methods:

700 primary care physicians who routinely used NSAIDs to manage their patients were questioned to probe their understanding of the potential importance of blood loss in the OA populations they commonly treated with NSAIDs in a chronic fashion.

Results:

Approximately 50% of doctors surveyed measured their osteoarthritis patients’ haemoglobin routinely as part of a complete blood count (CBC). The remaining cohort of physicians only considered conducting CBCs if they believed there was cause for concern, with the most common reasons cited being anaemia/blood loss (90/80% of physicians respectively) or the patient showing signs of weakness and fatigue (78% of physicians).
When all doctors were queried on their understanding of normal range of haemoglobin (Hb) values, as defined by the WHO, significant variation in the absolute figures were reported with approximately 40% of physicians citing a low end range for normal that would actually place the patient below the threshold for anaemia.

Conclusion:

Physician practice in relation to carrying out blood tests in OA patients and their understanding of the potential significance of specific results obtained, namely haemoglobin values, varies substantially across the countries surveyed. As NSAIDs form a pivotal part in the chronic treatment of osteoarthritis and are well recognised agents that can precipitate blood loss, guidelines may be needed to advise physicians as to when monitoring a patient’s haemoglobin levels may be appropriate.

Published: December 2014

This study describes the investigation of degradation products of donepezil
(DP) using stability indicating RP-HPLC method for determination of
donepezil, which is a centrally acting reversible acetylcholinesterase
inhibitor. In order to investigate the stability of drug and formed
degradation products, a forced degradation study of drug sample and finished
product under different forced degradation conditions has been conducted.
Donepezil hydrochloride and donepezil tablets were subjected to stress
degradation conditions recommended by International Conference on
Harmonization (ICH). Donepezil hydrochloride solutions were subjected to acid
and alkali hydrolysis, chemical oxidation and thermal degradation.
Significant degradation was observed under alkali hydrolysis and oxidative
degradation conditions. Additional degradation products were observed under
the conditions of oxidative degradation. The degradation products observed
during forced degradation studies were monitored using the high performance
liquid chromatography (HPLC) method developed. The parent method was modified
in order to obtain LC-MS compatible method which was used to identify the
degradation products from forced degradation samples using high resolution
mass spectrometry. The mass spectrum provided the precise mass from which
derived molecular formula of drug substance and degradation products formed
and proved the specificity of the method unambiguously.
Analytical modeling of multi-layered printed circuit board using multi-stacked via clusters as component heat spreader

Published: December 2014

In order to help the electronic designer to early determine the limits of the
power dissipation of electronic component, an analytical model was
established to allow a fast insight of relevant design parameters of a
multi-layered electronic board constitution. The proposed steady-state
approach based on Fourier series method promotes a practical solution to
quickly investigate the potential gain of multi-layered thermal via clusters.
Generally, it has been shown a good agreement between the results obtained by
the proposed analytical model and those given by electronics cooling software
widely used in industry. Some results highlight the fact that the
conventional practices for Printed Circuit Board modeling can be dramatically
underestimate source temperatures, in particular with smaller sources.
Moreover, the analytic solution could be applied to optimize the heat
spreading in the board structure with a local modification of the effective
thermal conductivity layers.
Rising public awareness of energy efficiency of buildings enhanced by “smart” controls of the in-door environment
Authors: Pantovic Vladan , Petrovic-Becirovic Sanja
Published: December 2014

Buildings consume a significant amount of energy today and are expected to
consume even more in the future. This consumption necessitates the use of
fossil fuels such as coal and natural gas, both of which have significant
environmental impacts. While renewable energy sources remain promising, the
most of the energy supply will still use conventional fuels in the near term.
Therefore, improving the energy efficiency in buildings is critical, and one
of the central visions of ?smart buildings? is to reduce their energy use
while maintaining the same level of service and comfort. However, to make the
buildings meaningfully ?smart?, their envelopes must first be made compliant
with the current energy efficiency standards. In this paper we first examine
how the public awareness of energy efficiency was risen in Serbia through
different demonstration projects, funded by the state budget and through
implementation of the energy efficiency measures in public buildings, funded
by municipal funds and soft loans from the banks. Then, we describe how the
energy efficiency in buildings might further be increased by the use of new
technologies and smart networks for control of the energy consumption. We
finally argue that these controls should take into account the personal
variables (activity, clothing) along with environmental variables (air
temperature, velocity, and humidity) for an optimum thermal comfort to be
achieved in public and residential buildings.
Effects of piston speed, compression ratio and cylinder geometry on system performance of a liquid piston
Authors: Mutlu Mustafa , Kiliç Muhsin
Published: December 2014

Energy storage systems are being more important to compensate irregularities
of renewable energy sources and yields more profitable to invest. Compressed
air energy storage (CAES) systems provide sufficient of system usability,
then large scale plants are found around the world. The compression process
is the most critical part of these systems and different designs must be
developed to improve efficiency such as liquid piston. In this study, a
liquid piston is analyzed with CFD tools to look into the effect of piston
speed, compression ratio and cylinder geometry on compression efficiency and
required work. It is found that, increasing piston speeds do not affect the
piston work but efficiency decreases. Piston work remains constant at higher
than 0.05 m/s piston speeds but the efficiency decreases from 90.9 % to 74.6
%. Using variable piston speeds has not a significant improvement on the
system performance. It is seen that, the effect of compression ratio is
increasing with high piston speeds. The required power, when the compression
ratio is 80, is 2.39 times greater than the power when the compression ratio
is 5 at 0.01 m/s piston speed and 2.87 times greater at 0.15 m/s. Cylinder
geometry is also very important because, efficiency, power and work alter by
L/D, D and cylinder volume respectively.

Sacred and profane topography in a medieval Serbian parish - an outline
Authors: Bojanin Stanoje
Published: December 2014

This article presents a basic research scope of the social importance of
microtoponyms and topographical features of villages and their precincts,
which in the Middle Ages were organized as parish communities. The social
space of the rural environment is segmented by different entities important
for the social and religious life of the local community, such as a parish
church with its yard, a cemetery, other churches and chapels in the fields
and groves, freestanding crosses, certain bodies of water or some marked
trees, typically the oak. The issue of the methods of analysing medieval
sources of different provenience and fragmented data is of major importance.
In order to understand the sources properly, we have to be aware of the
social segmentation of a medieval society, from which diverse interpretation
and functions of the cultural artefacts and performances (rituals,
festivities) originated.
St Sava and the cloud-chasers
Authors: Loma Aleksandar
Published: December 2014

A gloss in the Nomocanon of St Sava condemns folk superstitions related to
magically provoking hailstorms and eclipses. St Sava?s miracle with the king
of Hungary as described in his Vitae seems to go back to the same complex of
popular beliefs. Its acceptance by the hagiography was probably due to the
influence of the figure of prince magician as common to the Serbian and the
Russian oral epics.

la celebre imperatrice bulgara di origine serba. Si ? ribadito sulle sue
attivit? e le relazioni con vari personaggi dell?epoca a partire dal
matrimonio con Michail III Sisman Asen, despota di Vidin, fino alla morte di
lei, probabilmente avvenuta nel 1346 a Dubrovnik. Parole chiave: Impero

L’impératrice byzantine et la cour (XIIIe-XVe siècle)
Authors: Malamut Élisabeth
Published: December 2014

The article focuses on the Byzantine empress and the court in the empire of
the Lascarides and under the Palaiologoi. It studies the arrival of the
Byzantine imperial princess, the ceremonial of her marriage and her
coronation. All sources emphasize the prokypsis of the newly crowned bride
and the role of the mother-in-law. Orthodox ceremony remains in force and the
latitude granted to the early fifteenth century Latin princesses to dispense
appears not to be respected. Then the author examines clothing and insignia
of the Empress of the time of the Palaiologoi, then questions the role of the
Empress in the march of the empire: receiving the women at the court,
assistance at the counseling, at last in her presence in urban life. Finally
it seems that the empresses from the West kept with them the retinue that had
accompanied them from their country of origin and practiced a way of life
freer than the princesses that came from the Orthodox world. The author
concludes with the ?noise of the Gynekeion?.
Chartes portant sur les adelphata contribution à la diplomatique Byzantino-Serbe
Authors: Zivojinovic Mirjana
Published: December 2014

The study of the formulas of the Byznatine adelphortorika acts enables us to
conclude that the Serbian charters (1317/1318, ca 1321 and 1332) concerning
the establishment of the adeplphata, are authentic copies. Those documents,
created in Chilandar, each consist of two individual acts - request of the
future adelphatarios and the decision by the Assembly of Brotherhood, which
were most likely created at the request of hegoumenos Gervasios.
The lost traces of the frescoes on the western frontage of the ascension Church in Zica
Authors: Vojvodic Dragan
Published: December 2014

On the lower layer of the fa?ade mortar that once covered the western
frontage of the Zica katholikon, traces were registered of the figure of an
archangel (the western face of the tower) and parts of ornamental friezes
(southern wing of the narthex fa?ade and the northern oculus). Consideration
of the data provided in earlier documentation leads one to conclude that this
referred to traces of painting done during the renewal of the Ascension
Church in the time of Archbishop Danilo II.

The short comments aim at (a) a better understanding of the so-called Zealots
Movement in Thessaloniki in the frame of the moral destitution and the
elements of decline of the Empire during the years of the civil wars of the
14th century and (b) the analysis of the first sermon Gregory Palamas
delivered upon entering in Thessaloniki as its archbishop which reflects his
opinion concerning the movement.
A prolusion on the history of the text of Dusan’s Code
Authors: Bubalo Djordje
Published: December 2014

Based on the analysis of the manuscript tradition behind Dusan?s legislation,
this prolusion offers arguments in favor of including legal texts copied with
Dusan?s Code into a textological examination which aims to reconstruct the
history of the Code?s text (the genealogy of its manuscripts) and its
original recension. The analysis also includes manuscripts belonging to the
so-called incomplete Dusan?s legislation, which contains copies of the
accompanying texts without Dusan?s Code itself.

A small poem of six political verses published by Alexander Turyn from a
Greek manuscript in Venice compiled in 1321 classifies six ethnic groups:
gypsies, Albanians, Cretans, Germans, Goths in Crimea and Trapezuntinians.
The article examines firstly the manuscript and the copists and than the role
of the six groups in politics and society of the Late Byzantine Empire. The
poem have, as it seemed, its origins in merchant circles in Constantinople
and describes the public meaning in the streets and places of the Capital.

capital of the Serbian Medieval state, are among the most impressive remnants
of Late Medieval architecture in the Balkans. Despite the attention given to
the complex in scholarship, many of its visible and invisible aspects still
remain unresolved and deserve further investigation.

Costantino Continuato. Ideologia e iconografia del carisma imperiale bizantino agli albori dell’ età moderna
Authors: Ronchey Silvia
Published: December 2014

In the second half of the 16th century, after the definitive Turkish conquest
of Constantinople, the titulus of Constantine came to be perceived in a
fundamentally new way within the design to reaffirm papal authority,
culminating in the pontificate of Aeneas Sylvius Piccolomini. Diplomatic
wrangling and the strategic plan to save Byzantium in the West in the two
decades after the fall of Constantinople had and would have had the precise
aim of reinstating the hereditary title of the Byzantine Caesars, transferred
to the East by Constantine and never extinguished, within the orbit of papal
influence. The seat of Peter and the sceptre of Eastern Christianity should
have been symbolically reunited in the ?New Byzantium,? which would have had
its base at Rome and its bridgehead at Mystras. The project failed also
because its main supporters died one after the other within a short period of
time. But during the decades when it was pursued, we witness a true revival
of the figure of Constantine and an accentuation of the symbolic primacy and
legal significance of his title in the deliberations and political actions of
humanist intellectuals, and their reflection in the artistic commissions of
the period.
Despot Lazar Brankovic
Authors: Spremic Momcilo
Published: December 2014

Despot Lazar Brankovic was a son of despot Djuradj Brankovic and despoina
Jerina (Irina), born Cantacuzenus. He was in exile with his parents in
1439-1444, in Hungary, Italy, Ragusa, Zeta. He married Helen, the daughter of
Thomas Paleologus, despot of Morea in 1446. At that occasion he was crowned
with the crown of despots, because his older brothers, Grgur and Stephen, had
been blinded. Thus he became the heir to the Serbian throne and his father?s
co-ruler. When despot Djuradj died, on December 24th, 1456, he became a Serbian
ruler. In the extremely difficult political conditions, he maneuvered between
Turkey and Hungary. He entered a hard dispute with his mother, who was
supporting the blind Grgur in his attempts to seize the power. He was
poisoned by the nobility, which blamed him for alleged matricide.
Saint Sisoes above the grave of Alexander the Great. A monastic theme of post-Byzantine art and its examples from the 17th century Serbian painting
Authors: Zivkovic Milos
Published: December 2014

The depiction of St. Sisoes above the grave of Alexander the Great was
formulated at the end of the 15th century. The image in question is a visual
interpretation of a short song (?I see you, grave?), and it was often painted
in the churches throughout the Balkans during the next two centuries. With
references to the textual basis of this iconographic theme, as well as its
meaning, the article is devoted to insufficiently studied Serbian examples of
frescoes of St. Sisoes above Alexander?s tomb, preserved on the walls of
several churches painted in the first half of the 17th century.
