Cotton fabrics were treated with cosmetic substances based on α-tocopherol and cyclodextrine. Isolation of α-tocopherol from cotton cosmetotextiles was performed using three different techniques: ...stirring, Soxhlet and microwave extraction. High performance liquid chromatography (HPLC) was optimised and applied for the quantification of α-tocopherols in the isolates. The results revealed that all techniques are applicable for the isolation of α-tocopherol from cotton cosmetotextiles. The HPLC method proved to be the most convenient for the quantification of α-tocopherol from cotton fabrics.

U suvremenom svijetu ideja održivog razvoja postaje sve popularnijom, a razlog tome je intenzivan razvoj koji nije vodio računa o zaštiti okoliša i prirodnih resursa te sve veća svjesnost ljudi da ...današnji stil života sve više ugrožava okoliš. Svakodnevno se spominje održivi razvoj, održivo gospodarstvo, održivo društvo, ali i postavlja pitanje koliko i kako pojedinac ili interesna skupina razumije i percipira značenje pojmova održivi razvoj i održivost. Definicije održivog razvoja su različite, a jedna od najprihvatljivijih definicija je ona koju je dala Svjetska komisija za okoliš i razvoj u svom izvješću u kojem se održivi razvoj definira kao razvoj koji zadovoljava potrebe sadašnjih generacija bez ugrožavanja mogućnosti budućih generacija da zadovolje svoje potrebe. Održivi razvoj može se smatrati otvorenim procesom koji neprekidno vodi do promjena ciljeva i prioriteta, a ima za cilj postizanje održivosti u svim aspektima ljudskog života. Kako se u kontekstu održivog razvoja pozicionira tekstil i percipira tekstilna industrija dovoljno govori činjenica da se globalno, tekstilna industrija još uvijek smatra jednim od najvećih zagađivača okoliša, a sam tekstil kao sve veća i rastuća ekološka prijetnja. Da bi se postigla sukladnost tekstila i tekstilne industrije s konceptom održivog razvoja potrebno je principe održivosti ugraditi u sve segmente proizvodnje tekstila, počevši od dizajna (eko-dizajna, zelenog dizajna ili održivog dizajna), korištenja održivih sirovina i održivih načina proizvodnje pa sve do krajnjeg zbrinjavanja ili odlaganja otpadnih tekstilija na kraju njihova životnog ciklusa.
Zahtjevi današnjice nameću sve veću potražnju za inovativnim i viskoučinkovitim tekstilijama koje mogu olakšati i poboljšati stil života. Iz razloga što su kozmetički proizvodi široko dostupni te ...dodatno što njihova primjena ponekad zahtijeva izdvajanje puno vremena, proizašla je ideja o jednostavnoj aplikaciji kozmetičkih proizvoda na tekstil. Način vezanja tekstila i kozmetičkog sredstva omogućava kontrolirano otpuštanje kozmetičkog sredstva s tekstila. Svrha ove obrade je otpuštanje aktivnih tvari u željenom trenutku ili određenom vremenskom razdoblju uz istovremeno postizanje zadovoljavajuće postojanosti na pranje. Pritom je kemizam otpuštanja problematika kojoj treba posvetiti posebnu pažnju. U ovom radu je detaljnije opisan pojam kozmetičkog tekstila ili kozmetotekstilija, prikazana je njihova podjela, namjena, a dodatno je obrađena i problematika otpuštanja aktivnih tvari i postojanosti obrade. Na kraju je dan osvrt na moguće smjerove razvoja ove sve popularnije završne obrade tekstilnih materijala kojima tekstil dobiva dodatna svojstva i postaje proizvod visoke vrijednosti.

Falls are the most common cause of spinal cord injuries (SCIs) in patients older than 65. The worldwide annual incidence of SCIs is reported to be
around 15 – 40/ 1000000.
The aim of this study was to assess pregnant women's knowledge and attitudes regarding maternal COVID-19 immunization during pregnancy.
A cross-sectional study was performed in two teaching hospitals ...between May and October 2021 in Zagreb, Croatia. During antenatal clinic visit pregnant women were approached and asked to fill out a predesigned questionnaire about their knowledge and attitudes towards COVID-19 vaccination. Collected data was later analyzed.
A total of 430 women participated in the study. Only 16% of women expressed their willingness to be vaccinated against COVID-19 if offered, despite that 71% of them believe that COVID-19 might be a serious illness in pregnant women. The most important obstacle in having better acceptance of the vaccines is in the assumption that the vaccines are not safe for pregnant women (73%) or the fetus (75%), or that the vaccines are not effective (41%). The relationship exists between acceptance of vaccination in general and willingness to get other vaccines in pregnancy and readiness to be vaccinated against COVID-19 in pregnancy. Only one out of 55 women who were not adherent to the current vaccination recommendations in Croatia would accept the COVID-19 vaccine during pregnancy if offered. 21 (5%) women stated that vaccination against influenza and pertussis during pregnancy is necessary and 13 (62%) of them would get vaccinated against COVID-19 if offered.
This study showed that the crucial reasons for refusing vaccination against COVID-19 among pregnant women in Croatia are the concerns about the vaccines' effectiveness and safety. All healthcare providers should put more effort into education of pregnant women on risks of COVID-19, as well as on the benefits and safety of the vaccines.
Rheumatoid arthritis occurs two to three times more often in women than in men and it has been less studied in men. The results of gender influence on clinical course of the disease are ...contradictory. The aim of this study is to determine the difference in handgrip strength between female and male RA patients in comparison to healthy individuals. The study included 100 RA patients and 100 healthy individuals (50% were male in both groups). Handgrip strength was measured in both hands using a dynamometer. A two-way ANCOVA was used to analyse the data and age was included in the study as covariate. The results show that both male and female RA patients have lower handgrip strength compared to healthy individuals. The analysis of gender and disease interaction has shown that male RA patients have lower handgrip strength than female RA patients in comparison with the healthy group, age adjusted. This interaction is evident and statistically significant in both right hand (
F
1, 195) = 14.62;
p
< 0.01) and left hand (
F
1, 195) = 20.54;
p
< 0.01). The common-language effect size has shown that there is 92% (right hand) and 93% (left hand) chance that male individual will have stronger handgrip than his female counterpart. In RA patients, there is 77% chance for both hands that male will have stronger handgrip. Men and women with RA have significantly lower handgrip strength compared to healthy individuals and the difference is more pronounced in men which was not previously observed in the literature.
Background: The prognosis of rectal cancer has improved with neoadjuvant treatment for locally advanced disease. Twenty percent of patients respond to treatment with complete pathological regression, ...which is clinically estimated with magnetic resonance imaging. Aim: describe the properties of the pathological complete response group of patients at our institution Materials and methods: All selected patients received LCCRT at the University Hospital for Tumors Sestre milosrdnice University Hospital Center, Zagreb, between January 2014 and December 2019 and were later surgically treated at the same facility. Results: We identified 23 patients with complete pathological responses, of which, despite surgery, seven progressed. We recorded a higher proportion of female patients in that group and younger age of onset. MRI preoperatively was not yet predictive of a complete pathological response. Conclusion: The proportion of patients with a complete pathological response is 16% in this cohort. All patients underwent surgery but did not receive consolidating therapy. About 30% progressed during the observed period.
BACKGROUNDThe main benefits of cryotherapy in rheumatoid arthritis (RA) are in reducing inflammation and swelling and in relieving joint pain. This study aimed to compare the short-term effects of ...cold air therapy vs. ice massage, on pain and handgrip strength (HGS) in patients with RA. SUBJECTS AND METHODSThe study is a non-randomized clinical trial. Patients were recruited if they had disease activity score (DAS28) ≥3.2 with at least 2 swollen joints on the dominant hand and were consecutively divided into two groups of 15 patients. There was no statistically significant difference in DAS28 score between groups. The first group received cold air therapy at -30°C and the second ice massage of the hands. The pain (visual analogue scale, 0-10), and HGS (kg) were measured immediately prior and after cryotherapy, and 30 and 60 minutes after cryotherapy. Descriptive statistics, Independent Samples T-test, and Paired Samples T-test were used for statistical analysis. RESULTSPain intensities for cold air therapy were as follows: 5.33 (±2.44), 3.13 (±2.67), 2.87 (±2.56), 2.80 (±2.73), and for ice massage were: 5.20 (±2.37), 2.87 (±2.42), 2.60 (±2.23), 2.67 (±2.28). In both groups pain was significantly lower immediately after, 30 and 60 minutes after the treatment compared to the baseline (p=0.001). There was no significant difference in pain alleviation between the groups regarding the used method of cryotherapy on all three measured time points. Nonsignificant improvement in HGS occurred after both methods of cryotherapy. There was no significant correlation between pain intensity and HGS. CONCLUSIONSA single application of cold air therapy and ice massage equally provides immediate and significant pain alleviation in patients with active RA, which is maintained for one hour. There is scientific evidence that HGS is influenced greatly by the disease activity. A single application of cryotherapy could not reduce disease activity explaining recorded nonsignificant effect on HGS.
Abstract Among various nano-scaled materials composed from a spectrum of chemical compounds, inorganic nanoparticles are very attractive due to their physico-chemical properties, as well as their ...availability, simplicity, possibility of modifications, stability and biocompatibility. They are, on the one hand, an useful tool in advanced analytical chemistry, in particular for studying of biologically-relevant processes, but also important as functional parts of the systems designed for controlled and targeted delivery of medicaments for treatment of a variety of diseases and for imaging. So far, thousands of compounds and systems have been developed for the above-mentioned purposes, but there are only a few reviews dealing with these topics. The aim of this review is, thus, to summarize recent applications of nano-structured inorganic materials in the field of drug delivery, bioimaging and bioanalytics, and to give a prospective from the standpoint of biology-related applications.
Uvod: Prognoza raka rektuma poboljšana je neoadjuvantnim liječenjem lokalno uznapredovale bolesti. Dvadeset posto pacijenata reagira na liječenje potpunom patološkom regresijom, što se klinički ...procjenjuje magnetskom rezonancijom(MR).
Cilj: opisati svojstva skupine pacijenata s patološkim potpunim odgovorom u našoj ustanovi
Materijali i metode: Svi odabrani pacijenti primili su LCCRT u KBC-u Sestre milosrdnice, Zagreb, između siječnja 2014. i prosinca 2019. te su kasnije kirurški liječeni u istoj ustanovi.
Rezultati: Identificirali smo 23 pacijenta s potpunim patološkim odgovorom, od kojih je, unatoč operaciji, sedam imalo progresiju bolesti. U toj skupini bilježimo veći udio bolesnica i mlađu dob pri dijagnozi. Magnetska rezonanca prije operacije nije bila pouzdan pokazatelj potpunog patološkog odgovora.
Zaključak: Udio pacijenata s potpunim patološkim odgovorom je 16% u ovoj kohorti. Svi pacijenti su operirani, ali nisu primili konsolidirajuću kemoterapiju. Oko 30% je imalo progresiju bolesti tijekom promatranog razdoblja.
