Autori u radu pišu o političkoj situaciji u Banja Luci od 1990. do kraja 1992. godine. To je period od održavanja prvih višestranačkih izbora do perioda intenzivne kampanje protjerivanja i masovnih zločina u Banja Luci. Osim osvrta na rezultate izbora 1990., demografska slika opštine prema popisu stanovništva u Bosni i Hercegovini 1991. godine imala je veoma važnu ulogu u odnosu prema brojčano manjinskim narodima. U Banja Luci i cijeloj Bosanskoj krajini već su 1991. godine bile vidljive refleksije agresije Jugoslovenske narodne armije (JNA) na Hrvatsku, što je dovelo do zaoštravanja međunacionalnih odnosa. Izbijanjem agresije na Republiku Bosnu i Hercegovinu 1992. godine počinjeni su masovni zločini nad banjalučkim civilima bošnjačke i hrvatske nacionalnosti od strane Vojske Srpske Republike BiH (VSrRBiH) / Vojske Republike Srpske (VRS) i pripadnika policijskih struktura pri Ministarstvu unutrašnjih poslova (MUP) SrRBiH/RS. Terorisanje, zločini, prisilno odvođenje u logore i druga mjesta zatočenja te progon nad pripadnicima ova dva naroda nastavljeni su i nakon 1992. godine o čemu govore relevantni dokumenti i svjedočenja očevidaca.

Abstract Congenital intrinsic obstruction at or near the duodenojejunal junction is exceptionally rare and most commonly results from incomplete embryonic recanalization, leading to the formation of a mucosal web. We report a 7-day-old term male neonate (birth weight 3350 g) who presented with persistent feeding intolerance and intermittent bilious vomiting since birth. Abdominal radiography showed marked dilation of the stomach and duodenum with distal bowel gas. An upper gastrointestinal contrast study revealed a conical narrowing at the duodenojejunal junction. Surgical exploration revealed a mucosal web located immediately distal to the duodenojejunal junction. Given the marked luminal disparity, simple web excision was deemed inadequate, and segmental resection with primary end-to-end jejunojejunal anastomosis was performed. Postoperative recovery was uneventful. Proximal jejunal webs near the duodenojejunal junction are rare but surgically correctable causes of neonatal bilious vomiting and should be considered in the differential diagnosis.

Introduction Sepsis is a global health priority with nearly 50 million cases annually. Cardiovascular dysfunction is common, frequently manifesting as hypotension that persists despite fluid resuscitation. Most affected patients require the use of intravenous (IV) vasoactive agents, typically necessitating intensive care unit (ICU)-level monitoring, invasive interventions and contributing substantially to healthcare costs. Midodrine, an oral alpha-1 agonist approved for orthostatic hypotension, has increasingly been used off-label as a vasopressor-sparing (reducing IV vasopressor use) strategy in sepsis, despite limited and inconsistent evidence. This pragmatic, randomised, open-label trial evaluates the efficacy and safety of midodrine in patients with sepsis-associated hypotension. We hypothesise that, compared with standard care, midodrine administration will reduce the duration of IV vasopressor use. Methods and analysis A total of 308 adult patients with sepsis-associated hypotension will be enrolled (154 per arm). The intervention group will, in addition to standard of care, receive enteral midodrine 10 mg three times daily. Outcomes will be ascertained pragmatically via electronic health record-based data retrieval and adjudicated by research coordinators blinded to treatment assignment. The primary outcome is time alive and off IV vasopressors in the first 28 days (in hours) after randomisation. Secondary outcomes include cumulative vasopressor exposure; use and duration of central venous access; cumulative fluid balance over the first 48 hours and up to 7 days of ICU stay; ICU and hospital length of stay; and ICU-, hospital-, and organ support-free days through day 28. Safety outcomes include adverse events potentially attributable to midodrine during hospitalisation including acute kidney injury. Primary analyses will follow an intention-to-treat framework, including all randomised participants according to their assigned treatment groups. Primary and secondary outcomes will be compared using a van Elteren test stratified by randomisation factors. A predefined secondary Bayesian analysis of the primary outcome will provide complementary estimates of treatment effect. Safety outcomes will be summarised descriptively without formal between-arm hypothesis testing. Ethics and dissemination The Mayo Clinic Institutional Review Board approved this protocol and required written informed consent from all participants (IRB# 24–0 00 121). Findings will be disseminated through peer-reviewed publications and international conference presentations. Trial registration number NCT06319248.

In this paper, the dynamic analysis of a vibro-impact system with ideal excitation and various friction models is performed. A physical model of an oscillating mechanical system with possible impact occurrence is presented and the corresponding mathematical model is derived by using Lagrange’s equations of motion. To describe interaction between impact element and environment, three different friction models are considered: Coulomb, viscous and Coulomb-Stribeck model. Newton’s impact law with a coefficient of restitution is employed to describe relationship between pre-impact and post-impact velocities. The dynamic behavior of the vibro-impact system under the ideal excitation, where the system does not influence the excitation source, is investigated for each friction model by numerically solving the governing equations. The results of numerical analysis are presented through amplitude-frequency diagrams, displacement-time responses and phase portraits. The main objective is to determine the influence of different friction models on amplitude-frequency diagrams, particularly on the regions exhibiting impact and non-impact behavior. For parameter regions with multiple coexisting solutions, basins of attraction are constructed to illustrate the dependence of the system regime on initial conditions.

ABSTRACT Indoor spaces contain diverse microbial communities that shape human health. These microorganisms are particularly relevant to respiratory diseases, including asthma and allergies. Despite growing recognition of the importance of indoor microbial exposures, research in this field is slowed by differences in methods. These inconsistencies make it difficult to compare results and draw conclusions. This systematic review analyses 106 studies published between 2000 and 2025 that investigated indoor microbiomes in dust, air, and other matrices across homes, schools, and other built environments. We assessed sampling strategies, DNA extraction protocols, sequencing technologies, and bioinformatic pipelines, identifying trends, inconsistencies, and areas requiring harmonisation. Passive sampling, particularly dust collection, was the most common approach, while Illumina‐based 16S rRNA and ITS amplicon sequencing dominated molecular analyses. However, variations in targeted gene regions, extraction kits, and analytical tools limited cross‐study comparability. Ecological findings revealed consistent detection of bacterial taxa such as Staphylococcus, Streptococcus, and Corynebacterium, and fungal taxa including Cladosporium, Aspergillus, and Penicillium, with diversity shaped by building characteristics, ventilation, humidity, occupancy, and presence of pets. This review highlights the need for standardised protocols in indoor microbiome research to facilitate reproducibility, enable meta‐analyses, and inform health‐related guidelines for indoor environments.

BACKGROUND Schizophrenia (SCH) is a severe neuropsychiatric disorder associated with complex neurobiological alterations and suboptimal therapeutic outcomes. Increasing evidence indicates that mitochondrial dysfunction may contribute to SCH pathophysiology through impaired energy metabolism, oxidative stress, altered calcium homeostasis, and dysregulation of neuronal function. This review aims to summarize current knowledge regarding mitochondrial abnormalities in schizophrenia and to explore their potential involvement in the mechanisms of action of antipsychotic drugs. SUBJECTS AND METHODS A comprehensive review of the current literature was performed, focusing on human studies, cellular and animal models investigating mitochondrial alterations in schizophrenia, as well as studies evaluating the effects of antipsychotic medications on mitochondrial structure and function. RESULTS Available evidence demonstrates structural, molecular, and functional mitochondrial abnormalities in schizophrenia, including alterations in mitochondrial density, respiratory chain activity, oxidative phosphorylation, ATP production, and redox regulation. Antipsychotic drugs influence mitochondrial pathways in a complex and drug-specific manner. Some antipsychotics may impair mitochondrial respiration and increase oxidative stress, whereas others may exert compensatory or protective effects. Mitochondrial alterations may also contribute to cognitive impairment, negative symptoms, treatment response variability, and metabolic adverse effects associated with antipsychotic therapy. CONCLUSIONS Mitochondrial dysfunction represents an important component of schizophrenia pathophysiology and a potential therapeutic target. The interaction between mitochondrial pathways and antipsychotic drug effects highlights mitochondria as a possible pharmacodynamic interface for personalized treatment strategies. Further in vivo studies and biomarker-based approaches are required to clarify drug-mitochondria interactions and improve therapeutic outcomes in schizophrenia.

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by debilitating pain and progressive joint destruction. Tumor necrosis factor-alpha (TNF-α), a key pro-inflammatory cytokine, has been implicated in modulating both peripheral and central pain pathways. TNF-α inhibitors, initially developed to halt structural damage in RA, have demonstrated substantial efficacy in pain relief, independent of their anti-inflammatory properties. This narrative review explores the mechanistic pathways through which TNF-α contributes to pain sensitization and highlights the role of TNF-α inhibitors in disrupting these pathways. Evidence suggests that these biologics not only reduce synovial inflammation but also modulate neuroinflammatory circuits, altering pain perception at the spinal and supraspinal levels. Despite their clinical success, variability in patient response and concerns regarding long-term safety necessitate further research into personalized therapeutic strategies. Identifying biomarkers predictive of pain relief could enhance treatment precision. Ultimately, the integration of TNF-α inhibitors into multidisciplinary pain management approaches holds promise for improving clinical outcomes and quality of life in RA.

Cancer therapy remains challenged by limited treatment efficacy, cancer-related malnutrition and substantial toxicity, underscoring the need for novel strategies to improve therapeutic responses. Omega-3 fatty acids, particularly docosahexaenoic acid (DHA), exhibit both nutritional and bioactive properties, including anti-inflammatory effects and the ability to enhance tumor cell susceptibility to oxidative stress and ferroptosis. To improve stability and delivery, omega-3 fatty acids can be formulated into nanoemulsions that facilitate cellular uptake and may potentiate anticancer therapies. Therefore, we developed a panel of nanoemulsions with defined omega-3 and 9 fatty acid profiles derived from algae, fish and olive oils. All formulations exhibited high physicochemical stability, nanoscale droplet sizes and compendial quality. While pure oil showed minimal biological activity, nanoemulsification markedly increased cytotoxicity, and the novel DHA-rich algae oil emulsion displayed strong and selective antitumor effects without affecting normal fibroblasts. Combination studies indicated tumor type-dependent enhancement of chemotherapeutic efficacy. RNA sequencing indicated activation of ferroptosis-associated pathways and suppression of DNA replication and cell-cycle progression by the novel DHA-rich algae oil emulsion. To expand translational relevance for tumor specific target therapies, a HER2⁺/ER⁻ patient-derived breast cancer cell line and matched cancer-associated fibroblasts were established and characterized. In conclusion, these findings identify the new formulation prototype as a selective and biologically active nanocarrier for DHA which is capable of enhancing tumor type specific therapies, selective chemotherapeutic efficacy and potentially inducing ferroptosis-driven antiproliferative programs. These results highlight the promising potential of DHA as lipid component in a nanoscale droplet size formulation for future combination cancer therapies.

ABSTRACT Introduction: Repaired TOF (rTOF) is a common condition in adult congenital heart disease care. The aim of this article is to investigate how inflammatory markers and volume overload affect rTOF, and how these factors correlate with echocardiographic findings in the right heart cavities. Methods: This study included 32 adult patients (mean age, 27.44 ± 6.22 years) who had undergone surgical correction of TOF during infancy. All participants underwent transthoracic echocardiography, and laboratory assessments included measurements of N-terminal pro-B-type natriuretic peptide (NT-proBNP; reference range ≤125 pg/mL) and high-sensitivity C-reactive protein (hs-CRP; reference range ≤2.0 mg/L). Results: Significant correlations were found between NT-proBNP levels and right ventricular (RV) fractional area change (FAC) (r = −0.55, P = 0.001), tricuspid annular plane systolic excursion (TAPSE) (r = −0.35, P = 0.04), RV basal diameter (r = 0.47, P = 0.006), and right atrium (RA) area (r = 0.50, P = 0.003). Similarly, hs-CRP levels showed strong associations with RV FAC (r = −0.58, P < 0.001), TAPSE (r = −0.45, P = 0.009), RV basal diameter (r = 0.43, P = 0.01), and RA area (r = 0.43, P = 0.01). NT-proBNP had a significant impact (P = 0.017; EXP B = 0.982) on RV FAC. A decrease of 10 units in NT-proBNP was associated with a 17% reduction likelihood of having RV FAC <35%. Conclusion: The proinflammatory response (hs-CRP) and volume load (NT-proBNP) are directly correlated with echocardiographic parameters of the right heart cavities in patients with rTOF, suggesting that patients may benefit from treatment with anti-inflammatory drugs, as well as medications targeting diastolic dysfunction.

Hydrophobic eutectic solvent systems (ESSs) were prepared and characterized using temperature-dependent thermophysical and transport property measurements, supported by thermal analysis. The investigated systems comprise terpene-based mixtures, menthol:octanoic acid (1:2) and menthol:decanoic acid (1:1), and thymol-based mixtures, thymol:butanol (1:1), thymol:hexanol (1:1), thymol:octanoic acid (1:1), and thymol:oleic acid (1:1), as well as salt-containing ESSs based on tetrabutylphosphonium bromide (TBPBr), TBPBr:octanoic acid (1:1), and TBPBr:lauric acid (1:1). Density, dynamic viscosity, and electrical conductivity were measured at atmospheric pressure (p = 0.1 MPa) over 293.15–313.15 K. From density data, molar volumes and isobaric thermal expansion coefficients were calculated. The temperature dependence of viscosity was correlated with both Arrhenius and Vogel–Fulcher–Tammann equations. Conductivity results were used to compute molar conductivities, and the coupled conductivity–viscosity behavior was assessed via Walden analysis to quantify deviations from ideal electrolyte behavior and estimate ionicity. Thermal behavior and stability were evaluated by differential scanning calorimetry (DSC) and simultaneous thermogravimetric analysis (TG/DSC). The resulting dataset enables a consistent comparison of volumetric, flow, and ion transport descriptors across fully molecular terpene-based mixtures and TBPBr-containing systems. Overall, the combined transport descriptors, including Walden analysis, provide a practical framework for distinguishing molecular from salt-containing hydrophobic ESS families and support formulation selection for temperature-dependent applications, particularly in biphasic extraction processes.
