Pregnancy and postpartum periods are known as sensitive periods in women’s life and COVID-19 pandemic seems to be worsening their mental health with major impacts on exclusive breastfeeding duration. Therefore, the present study aims to fill the gap in the literature by assessing the links between postpartum anxiety and depression symptoms and breastfeeding duration as well as the associated factors during the COVID-19 pandemic. A longitudinal prospective observational study was conducted between November and [...]

In conventional wireline and LWD/MWD formation testing, downhole predictions for rock and fluid properties are based on simplified Darcy flow models, but only for mathematical expediency. These require initially constant pressures that are uniform throughout the reservoir. This limitation precludes common applications in overbalanced drilling, so that supercharge or near-well invasion effects - associated with rapidly decreasing pressures at the sandface where pressures are measured - are completely ignored. Such 1 [...]

Transplantation is a widely accepted and successful life-saving treatment for hundreds of thousands of patients. However, transplant medicine still faces a number of obstacles. One of the most significant is the large disparity between the number of donors and recipients and the growing need for re-transplantation. In the last two decades, the improvement and organization of the national transplantation program in Croatia have resulted in a steadily increasing donor rate and therefore the transplantation numbers. A [...]

Cancer continues to be one of the leading causes of global death, and conventional therapies have limited efficacy because of their toxicity, drug resistance, and off-target effects. Plant-derived nanoparticles (PDNPs) have emerged as suitable alternatives as they have biocompatibility, biodegradability, and multifunctional therapy. In this review, we discussed the recent advancements in PDNPs for cancer therapy, including the green synthesis of PDNPs using phytochemical (flavonoids, terpenoids) reducing and cappin [...]

Vitamin D, a fat-soluble secosteroid, plays a pivotal role beyond its functions in calcium and bone homeostasis. Emerging evidence suggests its involvement in glucose metabolism and insulin sensitivity, thus influencing the pathophysiology of Type 2 Diabetes Mellitus (T2DM). For the current review, a search was conducted across four major databases: PubMed, Embase, Google Scholar, and Web of Science. The aim was to identify relevant studies and clinical trials, published in English, reporting the mechanistic insigh [...]

Fluid management intra- and post-operatively for kidney transplant recipients (KTR) is essential to maintain adequate perfusion to the kidney. 0.9% normal saline (NS) is commonly used, but it can cause hyperchloremic metabolic acidosis, which may result in hyperkalemia and lead to delayed graft function (DGF). Plasma-Lyte A (PA) is an alternative option that has a lower amount of chloride and a neutral pH, which may offset the risk of hyperkalemia. The aim of this study is to determine the incidence of DGF in KTRs [...]

The modern globalized civilization is sustained by interactions, trade, the transportation of goods, and energy. Energy self-sufficiency is crucial in rural and disaster-prone areas like North Euboea because dependence on external energy supplies can leave regions vulnerable to supply chain disruptions, price volatility, and geopolitical risks. In such isolated regions, energy independence ensures resilience in natural disasters and economic instability. The alternative to self-sufficiency often involves reliance o [...]

The thermal cracking of methane (TMC) is a significant reaction occurring above 850°C, which proceeds in two stages: non-isothermally and isothermally. However, most existing studies have focused on obtaining reaction rates under isothermal conditions [1], limiting their applicability to practical industrial reactor conditions. This novel research aims to determine the overall thermal decomposition rate of methane to hydrogen and carbon in adiabatic conditions, covering the range of unstable industrial reactor temp [...]

The study aims to reveal autism vectors that are inherent in 3-4-year-olds with ASD. Three hundred eighty-three children with ASD took part in the research. An online questionnaire developed earlier by our research group was used. In the first stage, with the repeated use of exploratory factor analysis, the task of identifying the simplest factor structure was solved. As a result, a 7-factor system was obtained, including from 9 to 14 items in each factor (78 items in total): 1) "Persistence on sameness" (Sam); 2) [...]
