In this research, CdO-ZnO nano-photocatalysts were synthesized in various compositions by ultrasound assisted co-precipitation method. The samples were investigated via analyses of XRD, FESEM, BET, DRS, FTIR and EDX dot mapping to determine the physical, chemical and optical properties of the nanocomposites. Successful synthesis of CdO-ZnO photocatalyst in crystalline form was confirmed by XRD analysis resulting lower crystallite sizes for ZnO compared to CdO in the composites. The FESEM analysis demonstrated a nanostructured catalyst with a distinct decrease in particle size by addition of CdO to ZnO photocatalyst...

p16÷Ki-67 dual-stained cytology, either alone or combined with human papillomavirus (HPV) 16÷18 genotyping, could be a useful tool for triage for colposcopy of HPV-positive patients. Based on this background, we aimed at comparing the diagnostic performance of the p16÷Ki-67 dual staining test, and high-risk HPV test for the detection of high-risk cervical intraepithelial neoplasia (CIN2÷3) in patients diagnosed with low-grade squamous intraepithelial lesion (LSIL) on Pap smear. We performed a retrospective study including 184 patients with LSIL cytology on Pap smear, of which 64 were referred for biopsy after colposcopy...

Normal human breast tissue consists of epithelial and nonepithelial cells with different molecular profiles and differentiation grades. This molecular heterogeneity is known to yield abnormal clones that may contribute to the development of breast carcinomas. Stem cells that are found in developing and mature breast tissue are either positive or negative for cytokeratin 19 depending on their subtype. These cells are able to generate carcinogenesis along with mature cells. However, scientific data remains controversial regarding the monoclonal or polyclonal origin of breast carcinomas...

At the beginning of the 1980-ies, HIV infection and AIDS were described for the first time, this among the population of men who have sex with other men. Nearly thirty years later, the MSM population is still a population under heightened risk for acquiring HIV infection and other sexually transmitted diseases. This study investigates sexually transmitted diseases as a risk for HIV infection. A total of 296 men who have sex with men (MSM) were included in this case control study. Differences among the frequencies of sexually transmitted diseases among the MSM of HIV positive and HIV negative status were tested...

A 54-year-old man, with a history of Cushing's disease diagnosed 32 years earlier, presented with edema, asthenia and general malaise. Abnormal laboratory studies depicted hypokalemia and metabolic alkalosis. A CT scan of the chest revealed a 3×3 cm tumor in the anterior mediastinum. The pathology was consistent with a thymic carcinoid. These findings led to a diagnosis of biochemical Cushing's syndrome secondary to ectopic secretion of ACTH. Thus, this patient suffered twice of Cushing's syndrome. The first instance was the consequence of an ACTH--secreting pituitary adenoma and the second of an ectopic secretion of ACTH...

Guillain-Barré syndrome is an acute demyelinating disease which presents in a classic form with muscular weakness and the lack of reflexes. There are multiple variations and atypical forms of the disease, being facial diplegia with paresthesia one of them. Also, the absence of reflexes in this syndrome is typical but not constant, since 10% of patients present reflexes. We describe a case of atypical presentation with bilateral facial palsy, paresthesia, brisk reflexes and weakness in the lower limbs in a 33 year old woman...

BACKGROUND/AIM: E-Cadherin is a marker with a controversial function. Its role is often interpreted in the context of the epithelial-mesenchymal transition. In ambiguous cases, it is used as a phenotypic marker of lobular subtype of breast carcinoma. It has been well-studied in primary cancer, but its expression after metastasis is not well-described. The aim of this study was to determine the evolution of E-cadherin expression in no special type (NST) primary breast carcinoma and to correlate this with that in distant, paired nodal metastases (LNM) and molecular classification...

This is a retrospective study using the test-negative case-control method to estimate seasonal 2010-2011 influenza vaccine effectiveness (VE) in Croatia. Of patients consulting a physician for influenza-like illness (ILI) and for whom a swab was taken, we compared RT-PCR influenza-positive and RT-PCR influenza-negative patients. We used a structured questionnaire and physicians' records to obtain information on vaccination status and potential confounders. We conducted a complete case analysis using logistic regression to measure adjusted VE overall, against A(H1N1)pdm09 and in age groups...

Understanding the country-specific epidemiology of disease, which may vary greatly among countries, is crucial for identifying the most appropriate preventive and control measures. An overview of the local epidemiology of viral hepatitis in Croatia is given in this paper. The overall prevalence of hepatitis B in Croatia is low (less than 2% HBsAg carriers in the general population). Hepatitis B incidence and prevalence began to decline significantly following the introduction of universal hepatitis B vaccination in 1999...

Between September 6 and 21, 2012, seven human cases of West Nile virus (WNV) neuroinvasive infection were laboratory confirmed in Croatia. The median patient age was 62 years (range 48-77). Five patients presented with meningoencephalitis and two patients with meningoencephalitis followed by acute flaccid paralysis. Four of them had an underlying disease (hypertension). Using enzyme-linked immunosorbent assay (ELISA), WNV-specific immunoglobulin M (IgM) and IgG antibodies of low avidity were detected in six patients, whereas one showed only IgM antibodies...

West Nile virus (WNV) is a small, enveloped, spherical virus that belongs to the family Flaviviridae, genus Flavivirus, Japanese encephalitis serocomplex. Natural reservoirs of WNV are birds, and the main vectors are mosquitoes of the genus Culex. There are seven genetic lineages of WNV. Lineages 1 and 2 are the most widely distributed (Africa, North and South America, Europe, Asia and Australia). About 80% of infections are asymptomatic. In 20% of patients nonspecific febrile disease occurs (West Nile fever)...

We report the first serological evidence of Usutu virus (USUV) infection in horses in Croatia. During 2011, 1380 horse serum samples from healthy animals were collected from six northern Croatian counties. All samples were first screened for West Nile virus (WNV) immunoglobulin G (IgG) antibodies using an enzyme-linked immunosorbent assay (ELISA). Sixty-nine WNV ELISA-reactive samples were further tested for WNV antibodies by a virus neutralization assay (VN assay) and plaque reduction neutralization test (PRNT), and USUV by a VN assay and tick-borne encephalitis virus (TBEV) antibodies by PRNT...

BACKGROUND: Mycobacterium tuberculosis (Mtb) infection may cause overt disease or remain latent. Interferon gamma release assays (IGRAs) detect Mtb infection, both latent infection and infection manifesting as overt disease, by measuring whole-blood interferon gamma (IFN-γ) responses to Mtb antigens such as early secreted antigenic target-6 (ESAT-6), culture filtrate protein 10 (CFP-10), and TB7.7. Due to a lack of adequate diagnostic standards for confirming latent Mtb infection, IGRA sensitivity for detecting Mtb infection has been estimated using patients with culture-confirmed tuberculosis (CCTB) for whom recovery of Mtb confirms the infection...

The last comprehensive publication on tuberculosis in Croatia and the earliest impact of war, besides the yearly routine reports, was done in 1996 in Croatian. We were, therefore, interested to explore incidence trends and to highlight the early post-war tuberculosis epidemiological patterns in the next ten years period (1996-2005). A retrospective analysis of epidemiological data on all registered tuberculosis cases in Croatia searching the databases of 21 Croatian Public Health Institutes and the National Tuberculosis Registry was made...
