Objective The objective of this study was to evaluate the root canal morphology of third molars in the Bosnia-Herzegovina population. Materials and methods A total of 241 extracted third molars (105 maxillary and 136 mandibular) were subjected to a clearing procedure. The specimens were categorized into ten groups based on the Alavi classification for maxillary third molars (MaxTMs), and six groups were based on the Gulabivala classification for mandibular third molars (ManTMs). Root canal type according to the Vertucci classification, the presence and position of lateral canals, and intercanal communication were analyzed using a stereomicroscope x15. Results MaxTMs had three roots in 77.13% of the samples. Among MaxTMs, the most common morphology was three fused roots (33.33%) and Vertucci’s type VIII (54. 28% of samples in Alavi’s Group IV). 60.29% of ManTMs have two separate roots (Gulabivala's Groups II and III). The most prevalent types in mesial roots were type I (41.46% in Group II) and type IV (48.78% in Group III), although type I predominated in distal roots (91.24% and 100% in Groups II and III, respectively). Conclusion Single-rooted third molars usually have a root canal morphology that is more favorable for endodontic treatment. In contrast, third molars with fused roots often have more complex root canal morphology.

In the last ten years, the development and research of advanced technologies, as well as their application in all segments of society, have led to major changes and reshaping of the new world. New innovations are occurring on a daily basis, but their application is not going fast enough due to the rigid infrastructure. However, in order to secure an optimal future, we all have to adapt to the changes that are coming. The developed countries have adopted the strict implementation of advanced technologies of Industry 4.0, some of which include: Internet of Things (IoT), Big Data, Cloud Computing, smart sensors, Radio Frequency Identification (RFID), 3D printing, advanced security systems, Virtual and Augmented Reality (VAR), etc. Robotics is the basic and first technology that has been implemented since the 60s of the last century, with artificial intelligence coming in the spotlight in the last ten years. Artificial intelligence is becoming a key to the development of advanced robots, as it enables them to adapt to unpredictable situations, to learn from experience and make intelligent decisions.Robots use AI to process sensor data, navigate, recognize objects, plan paths and interact with the environment. In short, artificial intelligence enables robots to be smart, whereas robotics uses AI to create autonomous and useful devices. This symbiosis contributes to progress in many industries, including healthcare, manufacturing and transportation. Artificial intelligence (AI) and robotics are two key fields that complement each other. The paper presents the trend of applied and approved patents in artificial intelligence and robotics, as well as an example of the use of artificial intelligence in advanced robots to perform certain tasks. Artificial intelligence (AI) is having an increasing impact on robotics, opening up many possibilities.

U radu je predstavljen postupak izbora najpogodnijeg numeričkog modela za utvrđivanje indeksa staništa (SI – site index) kao apsolutne mjere proizvodnog potencijala (boniteta) staništa jednodobnih nenjegovanih sastojina bijelog bora na karbonatnim supstratima u BiH. Objekat istraživanja su predstavljale jednodobne nenjegovane sastojine bijelog bora različitih taksacionih i stanišnih karakteristika. Metodom privremenih oglednih parcela prikupljeno je više općih i taksacionih podataka, a zatim su njihovom obradom i analizom utvrđeni najvažniji strukturni i proizvodni parametri sastojina odvojeno po relativnim visinskim bonitetnim klasama staništa (RB). Za utvrđivanje numeričkog modela za procjenu indeksa staništa (SI) primijenjene su metode korelacione i regresione analize, a za predstavljanje veličina osnovnih taksacionih elemenata prema veličinama SI grafička metoda. U cilju predstavljanja veličina osnovnih taksacionih elemenata po utvrđenim SI klasama uspostavljena je korelaciona veza između SI50 (pri starosti od 50 godina)i postojećih relativnih bonitetnih klasa (RB) jednodobnih sastojina bijelog bora. Ova veza je poslužila za izradu proizvodne diferencijacije staništa jednodobnih sastojina bijelog bora na karbonatnim susptratima u BiH koja omogućava prikaz veličina osnovnih taksacionih elemenata ovih sastojina zavisno od starosti i SI50. Poređenjem utvrđenih rezultata istraživanja s odgovarajućim rezultatima drugih autora zaključeno je da su jednodobne sastojine bijelog bora u BiH srednje produktivne.

This study aimed to explore how Dab1 functional silencing influences the expression patterns of different connexins in the developing yotari (yot) mice eyes as potential determinants of retinogenesis. Using immunofluorescence staining, the protein expression of Dab1, Reelin, and connexin 37, 40, 43, and 45 (Cx37, Cx40, Cx43, and Cx45) in the wild-type (wt) and yot eyes at embryonic days 13.5 and 15.5 (E13.5 and E15.5) were analyzed. Different expression patterns of Cx37 were seen between the wt and yot groups. The highest fluorescence intensity of Cx37 was observed in the yot animals at E15.5. Cx40 had higher expression at the E13.5 when differentiation of retinal layers was still beginning, whereas it decreased at the E15.5 when differentiation was at the advanced stage. Higher expression of Cx43 was found in the yot group at both time points. Cx45 was predominantly expressed at E13.5 in both groups. Our results reveal the altered expression of connexins during retinogenesis in yot mice and their potential involvement in retinal pathology, where they might serve as prospective therapeutic targets.

In hip fracture patients, who are mostly elderly, preexisting anemia can be worsened when combined with trauma and surgery. To this date, there is no unequivocal approach about transfusion thresholds. We analyzed hemoglobin (Hb) and hematocrit (Hct) levels at three time points in surgical patients with proximal femoral fractures (PFF) to see which levels were triggers for transfusions and whether transfusions were related to mortality after hospital discharge. A total of 956 patients were operated on from 1 January 2021 to 31 December 2022 at the University Hospital of Split and included in the study. There were more women (74%); 47% patients had admission Hb < 120 g/L. Transfusion was given preoperatively to 88, intraoperatively to 74 and postoperatively to 309 patients. Transfusion thresholds were as follows: Hb 84 g/L preoperatively, 99 intraoperatively and 83 postoperatively. After hospital discharge, 10.79% of patients died within the 1st month and 23% within 6 months. In the group of non-survivors, 60% of patients had admission Hb ≤ 117 g/L and the proportion of patients transfused preoperatively was two times higher. Preoperative transfusion thresholds could be set to higher levels for patients with surgically treated PFF. However, that could increase mortality even more. Further investigation is necessary.

Abstract Introduction The aim of this research was to examine the existence of broncho-obstruction of the airways in patients suffering from chronic obstructive pulmonary disease, as well as changes in resistance values in this part of the bronchial tree after inhalation of salbutamol. Methods This study was designed as a prospective, interventional clinical trial that included a sample of 147 patients suffering from COPD. Patients were stratified into four groups of thirty patients each based on the severity of airflow limitation (based on the post-bronchodilator FEV1 value), according to the GOLD grade. The test was conducted at the University Clinical Center Sarajevo, Clinic for Lung Diseases and Tuberculosis “Podhrastovi” Results The results of our research showed that the average values of FEV1 compared to the predicted values of this parameter in subjects in the GOLD 4 group before the administration of salbutamol were statistically significantly lower than the average values of FEV1 in other subjects of the GOLD group. After the administration of salbutamol, a statistically significant increase in the value of FEV1 was registered in all tested groups. When the response to salbutamol was compared among the GOLD groups, it was assessed that the difference in the percentage increase in predicted FEV1 values after the administration of salbutamol among the tested groups was not statistically significant. Conclusion Bronchodilation with salbutamol and additional ipratropium had a significant effect on both mentioned parameters, especially in the COPD group, which speak in favor of the presence of increased peripheral resistance in all groups of patients. A statistically significant bronchodilator response was obtained in GOLD 1 and GOLD 2 groups, i.e. in groups of patients with milder forms of the disease.

: Bijeli bor (Pinus sylvestris L.) jedna je od najvažnijih i najistraženijih vrsta drveća u evropskim šumama. Cilj istraživanja je utvrditi mogućnosti povećanja proizvodnih mogućnosti i kvaliteta bijelog bora kroz ranu selekciju u testu provenijencija u Bosni i Hercegovini, a rezultati će se koristiti u svrhu što boljeg korištenja staništa pogodnih za bijeli bor. Za potrebe ovog istraživanja 2021. godine mjerene su visine i prečnici u prsnoj visini bijelog bora u testu provenijencije u Žepču, te brojane grane u pršljenu. Test je uspostavljen 2012. godine sadnjom dvogodišnjih sadnica iz 14 evropskih provenijencija (po tri iz Austrije i Italije i po jedna iz Bosne i Hercegovine, Njemačke, Poljske, Rumunije, Slovačke, Norveške, Škotske i Ukrajine). Izračunate su i zapremine, a zatim provedena analiza varijanse i deskriptivna analiza podataka po provenijencijama. Zatim je selekcionirano pet provenijencija sa najvećim prosječnim vrijednostima istraživanih svojstava i izračunate su razlike između prosječnih vrijednosti za selekcionirane provenijencije i ukupnog prosjeka, kao i razlike između prosječnih vrijednosti za provenijenciju sa najvećim prosječnim vrijednostima i ukupnog prosjeka za sva istraživana svojstva. Podaci su obrađeni pomoću Excel 2013 i SPSS 20.0. Analiza varijanse pokazala je statistički značajne razlike između provenijencija po svim istraživanim svojstvima. Najveći prosječan prečnik stabala starih 11 godina imala je provenijencija iz Ukrajine, a najveću prosječnu visinu i zapreminu jedna od provenijencija iz Austrije. Razlika između prosjeka pet provenijencija sa najvećim prosječnim vrijednostima i ukupnog prosjeka po svojstvu zapremine iznosila je 17,4% od ukupnog prosjeka, a razlika između provenijencije sa najvećom prosječnom zapreminom i ukupnog prosjeka iznosila je 41% od ukupnog prosjeka. Rezultati će biti korišteni u procesima selekcije provenijencija bijelog bora sa dobrim visinskim i debljinskim prirastom.

Crna joha (Alnus glutinosa [L.] Gaertn.) listopadno je drvo iz porodice brezovki (Betulaceae) koje se uglavnom javlja u nizijskim područjima u blizini vodnih tijela različitog režima plavljenja, često prateći riječne i manje vodene tokove, formirajući zajednice azonalnog karaktera u Bosni i Hercegovini. Cilj istraživanja je razvijanje predikcijskog modela rasprostranjenosti staništa crne johe u Bosni i Hercegovini na osnovu poznatih i utvrđenih lokacija staništa crne johe i podataka WorldClim baze. Kao osnovni materijal istraživanja korišteni su podaci sa vlastitih terenskih snimanja i iz drugih relevantnih dostupnih izvora. Klimatski podaci su preuzeti sa WorldClim baze podataka u obliku rasterskih slojeva za 19 bioklimatskih varijabli. Modeliranje je provedeno koristeći metod maksimalne entropije integrisan u MaxEnt računarski program. Izbor modela se zasnivao na predikcijskoj tačnosti modela i koherentnosti sa distribucijom staništa crne johe trenutnog i prethodnih istraživanja. Dobiveni rezultati su potvrdili model veoma dobre predikcijske tačnosti na temelju kalibracije i validacije podataka subseta (AUC > 0,85). Varijable BIO6 (minimalna temperatura najhladnijeg mjeseca) i BIO14 (oborine mjeseca s najmanje padavina) imaju statistički najveći značaj i uticaj za model prostorne rasprostranjenosti ekološke niše crne johe. S obzirom na važne funkcije zajednica crne johe u prevenciji erozije, zaštiti od poplava i očuvanju biološke raznolikosti, dobiveni rezultati mogu doprinijeti upravljanju staništima crne johe. Rezultati predikcije staništa mogli bi se koristiti za daljnja istraživanja vezana za klimatske promjene i praćenje stabilnosti ekosistema.

AIM To investigate the risk for falls in elderly patients treated in the Primary Health Care Centre Gradiška, Bosnia and Herzegovina. METHODS This study included 500 patients aged 65 and older. They were chosen randomly by 10 family physicians. Data collection took place every Wednesday and Friday, between January 2022 and July 2022. The patients' gait and balance assessment were performed using the Tinetti Gait and Balance Tool to assess the risk of falls. A supplementary questionnaire was created to record data about the patients' age, sex, chronic diseases, and drugs they take. RESULTS Among the included patients there were 266 females (53.2%) and 234 (46.8%) males, with the mean age of 75.25 years. The Tinetti test showed that the risk of falls was high for patients older than 75 years, 111 patients (69.8%), and 48 patients (30.2%) aged 65 to 74 (p=0.000). The risk of falling was higher for female, 93 (35%), than male patients, 66 (28.2%) (p=0.018). Considering chronic diseases, a high risk of falls was found in 32 (2.1%) patients with heart failure (p=0.029) and 19 (11.9%) patients with osteoporosis (p=0.000). Patients who used antihypertensive drugs had the highest risk for falls, 124 (78.0%) (p=0.757). CONCLUSION About two-thirds of the examinees over the age of 75 had a high risk of falls, which indicates that family doctors should be more involved in fall prevention of elderly patients and constantly educate older patients and their families about it.

Simple Summary Patients with chronic lymphocytic leukemia (CLL) are more susceptible to infections, which are also the most common cause of death in these patients. Previous studies in patients with CLL described elevated levels of FOXP3+ regulatory T cells (Tregs), which also correlated with decreased T cell responses to microbial antigens. As the activation of the STAT5 transcription factor induces the expression of FOXP3 and human CD4+FOXP3+ T cells that also contain nonsuppressive T cells, we analyzed STAT5 phosphorylation (pSTAT5) and suppressive subpopulations, including activated Tregs (aTregs). We found a significantly increased frequency of aTregs in patients with advanced stages, which significantly correlated with the total tumor mass score. aTreg expansion in vitro was associated with significantly higher aTreg pSTAT5 responses to SARS-CoV-2 antigen-specific stimulation in vitro. Finally, a subgroup of patients characterised by an increased aTreg percentage among CD4+FOXP3+ T cells experienced a more severe disease course with serious grade ≥3 infections during follow-up. Abstract Introduction: Advanced chronic lymphocytic leukemia (CLL) is accompanied by increased circulating regulatory T cells (Tregs) and increased susceptibility to severe infections, which were also shown to entail a striking induction of FOXP3 expression in Tregs. As homeostasis of the most suppressive CD45RA−FOXP3high activated Treg (aTreg) subset differs, it is critical to analyse homeostatic signalling in Treg subsets. Materials and Methods: In this study, by using conventional and imaging flow cytometry, we monitored STAT5 signalling/phosphorylation (pSTAT5) and investigated Treg subsets in relation to the Binet stage, the total tumor mass score (TTM) and the disease course during a follow-up of 37 patients with CLL. Results: The aTreg percentage was significantly increased among CD4+ T cells from patients with advanced disease and significantly correlated with the TTM. A subgroup of patients with higher aTreg percentages among CD4+FOXP3+ T cells at the start of therapy was characterised by more frequent episodes of severe infections during follow-up. Conclusions: The results suggesting that an aTreg fraction could represent a possible marker of a severe disease course with infectious complications. Augmented homeostatic STAT5 signalling could support aTreg expansion, as higher pSTAT5 levels were significantly correlated with an increased aTreg frequency among CD4+FOXP3+ T cells during the follow-up of patients on therapy, as well as following SARS-CoV-2 antigen-specific stimulation in vitro.
