Biocompatibility of Dental Adhesives

The accomplishment of developing a truly adhesive bond between a restorative material and the natural tooth structures is the goal of adhesive dentistry. Dentine adhesive systems come into close contact with dental and oral tissue, especially the pulp and gingival cells. Due to this close and long-term contact, adhesives should exhibit a high degree of biocompatibility. Biocompatibility is one of the most important properties of dental materials, and adhesives are no exception. It has been long demonstrated that different components of adhesives can be released. Numerous in vitro investigations have shown that released monomers and other components can cause damage to cultured cells. In addition, many in vivo studies have shown that uncured components which reach the pulpal space cause inflammatory response and tissue disorganization. Only a combination of various in vitro and in vivo tests can provide an overview of the interaction of biomaterials with the host. Therefore, it is necessary on a regular basis to carry out and re-verify the biological compatibility of the increasing number of new dental materials. Adhesives should be biofunctional, protective, and preventive, with health-promoting effects that contribute to a better prognosis for restorative treatments and its biocompatibility

Usefulness of Unstimulated and Stimulated Whole Saliva, Accuracy of Minor Labial Salivary Gland Biopsy in the Diagnosis of Primary Sjögren's Disease: A Croatian Single-Center, Cross-Sectional Study

The aim of this cross-sectional study was to determine the accuracy of minor labial salivary gland (MLSG) biopsy in the diagnosis of primary Sjögren' s disease (pSD); to study the correlation between the focus score (FS) and anti-SSA/Ro, anti-SSB/La, anti-SSA and -SSB antibodies, unstimulated whole saliva (UWS) and stimulated whole saliva (SWS); to determine the role of UWS and SWS in the clinical evaluation of pSD patients and patients with sicca symptoms. Methods. A total of 37 subjects were enrolled in the study and divided into two groups: the test group consisted of 15 patients diagnosed with pSD; the control group consisted of 22 patients who had sicca symptoms but did not meet the 2016 American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR) diagnostic criteria. Clinical and laboratory tests, including saliva collection, MLSG biopsy, autoantibody titers, were performed in all patients. Results. The median of the FS was 1.00 [IQR=1.00-1.50] in the test group, whereas in the control group, it was 0.00 [IQR=0.00-0.00] (p< 0.001). The sensitivity, specificity, and accuracy of MLSG biopsy were 86.7%, 100.0%, and 94.6%, respectively. The results showed a correlation between the FS and antinuclear antibodies (ANA) (p=0.002). In addition, Pearson’s correlation showed a weak negative correlation between UWS (r=-0.058, p=0.73) and SWS (r=-0.022, p=0.90) and the FS. In the test group, 73.3% of patients had abnormal UWS values, while 86.7% had abnormal SWS values; among them, values of 0.00 ml/min for UWS and SWS were found in 60.0% and 26.7% of patients, respectively. Conclusions. Although MLSG biopsy has great diagnostic value and accuracy in diagnosing pSD, it is not always definitive. Our study found a statistically significant association between the FS and ANA, and the greater utility of SWS in diagnosing pSS

Specijalizirani arhivi

Danas smo s jedne strane suočeni s proizvodnjom nepreglednog broja informacija, a s druge, u velikoj mjeri upravo pod zastrašujućim pritiskom količine tih informacija, sa sve većom profesionalizacijom arhivske struke i nastojanjem da se pronađu što djelotvorniji načini za upravljanje i odabir ’pravih’ informacija za budućnost. Imajući u vidu ograničenja koja nam nameće sadašnja gospodarska situacija u Hrvatskoj, zatim nestanak društvenoga vlasništva i sve snažniju privatizaciju na svim područjima, bilo bi važno snažnije potaknuti osnivanje ili uređenje specijaliziranih i/ili ’kućnih’ arhiva na onim područjima koja arhivska služba sa svojim sadašnjim prostornim i ljudskim kapacitetima ne uspijeva savladati na zadovoljavajući način. Takve se potrebe javljaju na području gospodarstva, zdravstva, znanosti i obrazovanja, javnih medija. To nikako ne bi trebalo značiti slabljenje arhivske mreže i nadzora nad cjelinom arhivskoga gradiva u nastajanju. Specijalizirane arhive treba učiniti sastavnicom jedinstvene mreže arhiva

Villa Muć eiusque districtus in historia Croatorum

Le XIe Centenaire de Branimir (879—1979) rappelle aux Croates: a) l’arrivée de ce prince à la suprême autorité de l’Etat, au début de 879, et b) la lettre du pape Jean VIII, datée du 10 juin 879, p ar laquelle il re connaît les droits souverains de Branimir, c’est-à-dire proclame l’indépendance de la Croatie d’alors. Ce Centenaire nous offre l’occasion pour parler, ici, de la région de Mué, anc1. Zmina, où le prince Branimir possédait une propriété à comparer avec la ’villa’ classique des Romains. Dans son domaine, Branimir avait fait ériger, ou embellir, une église qui se trouvait à l\u27emplacement de l’actuelle église paroissiale St.-Pierre, à Gornji Muć. Cepedant, les fouilles de la partie non couverte par la nouvelle église sont toujours visibles. Cette étude est composée de trois parties: I. Tout d ’abord, on explique le nom actuel de Mué, en le faisant dériver du mot latin monticellus, probablement p a r l’intermédiaire du vénitien- -dalmate *montiellus. La première syllabe mont- était prononcée comme mont nasal des Slaves-Croates (VIIe — VIIIe s.) pour devenir, après la dénasalisation (IXe—Xe s.), un mut- du parle r croate (méridional). Ensuiite, il est question de l’histoire de Mué: origine, destruction par les Tatares (XIIIe s.) et par les Turcs (XVIe s.), repeuplement par les Croates (XVIe s.) et par les Vénitiens (XVIIe—XVIIIe s.), dominations étrangères (turque, vénitienne, française-napoléonienne et autrichienne), réformes agraires et cosiales avant et après la Seconde guerre mondiale, etc. II. La deuxième partie de cette étude concerne les fouilles effectuées à Gonnji Muć et la découverte de l’insoription de Branimir. Les fondements de l’ancienne église ont été découverts, en 1871, p ar le curé de Meuć, Granić, de même que les trois fragments de Pencedmte (lat.: saeptum) qui sépairait le choeur, ou le presbyteriium, de la nef. Ces fragments réunis porten t fume inscription avec le nom de Branimir et avec la date de 888. Cette inscription, difficile à déchiffrer, a été, après Granić et Ljubié, examinée par Fr. Rački. Celui-ci en a proposé une assez bonne lecture que les autres historiens ont adoptée: [Tempore ducisi BRANIMIRI. ANNOR (um) XPI SACRA DE VIRG(ine) CARNE V T SV(m)PS(it)). S(eu) DCCCLXXX ET V ili. VI Q(ue) INDIC(tione). Au S(eu) de Fr. Rački, M. Barada a substitué S(unt). En 1964, le sacristain de l’église de Muć, Joseph Palinić, a trouvé un quatrième fragment. On peut y lire quelques lettres, en latin, qui appartiennent à la même inscription: NTI SALV(atio) NI TIBIQ(ve). . . Etant donné que le tex te complet de l’inscripition en question n ’est pas encore établi, il n ’est pas possible de préciser le niotm du saint Patron à qui l’église a été consacrée. III. Dans la dernière partie du présent travail, nous montrons que l’a c tu el Mućko polje n ’est pas autre chose que l’ancienne joupa (župa) croate Zmina (lat.: Smina, Zimina, Cimina), plus ta rd Zmino(-vo) ou Zminje polje (Turcs). Cette région est mentionnée plusieurs fois dans les annales de l\u27Église de Spliit: 1083, 1103, 1207, 1315, 1397, 1398, 1441, 1682, 1687, 1700 et au temps de D. Farlati (t 1773), historien des Églises illyriennes (Dalmatie, Croatie, Bosnie, Herzégovine, Diodée, Albanie, Serbie, Macédoine et Bulgarie). Après de nombreuses vicissitudes, Muć et Mućko polje sont, de nos jours, partie intégrante du territoire national croate.Saecula iam numerantur undecim a tempore quo Branimirus, inclutus dux Chroatorum, regni habenas, summo pontifice Johanne VIII plaudente, intrepidus assumpsit: 879—1979. Hoc A. D. 1979 volvente Branimirus in medio est studiorum ad qtiae viri historiam chroaticam oolentes inoumbunt. Simili modo etiam nobis, qui in eadem disciplina tantum amorem collocamus, perpauca dicenda sunt de territorio Sminae (postea: Simino, Smino, Sminovo, Zmino, Zmi nje polje; hodie: Mućko polje) in quo Branimirus villam vel possessionem suam tenebat, et de inscriptione eiusdem prinoipis quam fossores antdquae ruderibus extraxerunt ecclesiae in loco hodiemi S. Petri in Gomji Muć sitae. Inscriptio lapidea, in qua tarn nomen praefati principis quam annus Domini facile leguntur, inventa est A. D. 1871 in loco dicto Mué, qui Andetrio Illyriorum primo et Romanorum postea se substituit. Disserta lo nostra historiam districtus villaeque Muć spectans atque elucubrans tribus contexta capitibus exhibetur: I. In capite primo nomen hodiemum Muć a voce latina monticellus >*montiellus derivare p u tatu r; cuius vocalis -on, siouti Slavis mords est, saeculo IX nasalis -on eventa sed post saeculum X formarci -u communis nacta est. Porro autem historia villae Muć, ratione fontium habita, illustratur insuperque vitae publicae non minus quam privatae conditio exponitur ita ut res incolarum usque ad novissima tempora gestae veloci calamo conscribantur. II. In capite secundo de repertione fundamentorum ecclesiae, quam A. D. 888 Branimirus dux aedificare aut saltern adomare iussit, disseritur, nec non lapidariae saepto inscriptae litterae latinae accurate leguntur et, sit venia verbo, paullulum castigantur: [Tempore ducis] BRA NlMlRl. ANNOR(um) XP1 SACRA DE VIRG(ine) CARNE VT SV(m)PS(it). S(ev) DCCCLXXX ET V ili. V I Q(ve) INDIC(tione). Mentio quidem fit, qui monumentum A. D. 1871 invenit, parochi Granić, dmmo vero etiam de viris clarissimis, qui inscriptioni supradictae operam navarunt, commemoratur. A. D. 1964 vir probus Joseph Palinić, officio 72 sacristani fungens, cum cameram coemeterdi mortuariam restaurare voluisset, quartum eiusdem inscriptionis reperit f ragmen turn in quo vel plures litterae, nondum satis scrutatae, exstant: NTI SALV(atio)NI TIBIQ(ve). . . Attamen inscriptio ad nos mutila pervenit, qua de causa titulus ecclesiae primitivus, proh dolor, definiri nequit. III. In capito tertio Campus Muć (croatice: Mučko polje), uti nostra aetate nuncupatur, idem esse asseritur ac illa jupa Smina (župa Zmina, Zminovo, etc.) de qua in fontibus historiae chroaticae ab A. D. 1083 usque ad finem seaculi XVIII pluries sermo fit. Nomen quippe Zmina (lat.: Smina) a zmija (lat. : serpens), zmijina, zminja, zmina slavicae gentis originem ducit, quia omnis alia interpretatio plus minusve claudicai

Analysis of the distribution of weekly rest

U jednom industrijskom poduzeću izvršena je analiza distribucije periodiciteta tjednih odmora u tri periode vremena. Grupa radnika, prema kojoj smo uzimali podatke, radi u sve tri smjene i nema tjedni odmor u nedjelju nego u bilo koji dan u tjednu. Kod te grupe radnika utvrđeno je neperiodska distribucija tjednih odmora i produženi radni tjedan. Ta pojava utjecala je na povišenje drugih oblika apsentizma i vjerojatno na pogoršanje kvalitete proizvodnje pa i na druge pojave.The distribution of periodicity of weekly rest and its consequences have been studied in a factory operating in three shifts, where the weekly rests do not take place on Sundays, hut are spread all over the week including Sunday. This analysis has shown as follows: 1. The weekly rests are usually granted either successively or after a longer period of time, i. e. the weekly rests are not granted periodically and the distribution of periodicity of weekly rests is rather large (δ = 5,97). 2. The weekly rests are not granted as they ought to be, so that the average labour week is longer than it is justified or permitted. The average weekly rest takes place every 9,02 day. 3. The weekly rests are not planned equally, so that the number of workers having weekly rest varies greatly from day to day. i. e. there is a huge daily variation Ln the total number of workers having weekly rest. 4. Variations of the total amount of weekly rests on different days are not caused by any other form of absenteeism. 5. Variations in the number of weekly rests represent the major part of the total of variations of all forms of absenteeism. 6. The weekly rests take place on the days when the other forms of absenteeism are most frequent. 7. The above mentioned distribution of weekly rests \u27increases the number of accidents at work. On an average, the accidents at work take place 6.31 days after the previous weekly rests (M = 6,31). 8. The above mentioned distribution of weekly rests is likely to cause a lower quality of production and considerable financial losses. 9. This distribution of weekly rests probably influences the increase of other forms of absenteeism and exerts a negative influence on working morale. In order to improve the existing state, the following measures are recommended: 1. To introduce an efficient recording of all the forms of absenteeism and other relating data. 2. To schedule the weekly rests so as to distribute them equally, in equal periods of time. 3. To inform the workers about the scheduled days of weekly rests. 4. To schedule the distribution of annual vacation in order to make the equal distribution of weekly rests possible
