Under natural conditions, plants are regularly exposed to combinations of stress factors. A common example is the conjunction between nitrogen (N) deficiency and excess light. The combined effect of stress factors is often ignored in studies using controlled conditions, possibly resulting in misleading conclusions. To address this issue, the current study examined the physiological behavior of Arabidopsis thaliana under the effect of varying nitrogen levels and light intensities. The joint influence of low N and excess light had an adverse effect on plant growth, chlorophyll and anthocyanin concentrations, photochemical capacity, and the abundance of proteins involved in carbon assimilation and anti-oxidative metabolism...

The aim of this research was to simultaneously study the effect of meat type (chicken breast and leg meat), animal fatty acid composition (selected pork backfats having a low and high degree of saturation, respectively), and isothermal temperature (50, 60, 70, and 80 °C) on the viscoelastic properties of meat batters during and after application of different time-temperature profiles. Gelation of meat proteins contributed most to the viscoelastic properties of meat batters during heating, whereas crystallization of the lipids especially contributed to the viscoelastic properties during the cooling phase...

TMPRSS2/ERG is the most common type of gene fusions found in human prostate cancer. There are two important features of TMPRSS2/ERG fusions. One is that these gene fusions lead to ectopic expression of ERG, an ETS family transcription factor, in prostate epithelial cells from the 5' control region of an androgen/estrogen dual-responsive gene, TMPRSS2; the other is that ~60% of these fusions are generated via intrachromosomal deletion of the interstitial region between TMPRSS2 and ERG. To recapitulate these important aspects of TMPRSS2/ERG fusions, we generated several TMPRSS2/ERG knockin mouse models based on the endogenous Tmprss2 locus...

Luteolin, a common dietary flavonoid, induces the apoptosis of cells in several types of cancer. However, its role in myelodysplastic syndrome (MDS) and the potential underlying mechanisms remain to be elucidated. To evaluate the potential benefit and underlying mechanisms of luteolin in MDS cells, the viability of SKM‑1 cells and primary bone marrow (PBM) mononuclear cells from patients with intermediate‑ or high‑risk MDS were assessed using a Cell Counting Kit‑8 assay. The apoptotic features of cell morphology were assessed using Wright‑Giemsa staining, DNA fragmentation was analyzed by agarose gel electrophoresis, and the extent of apoptosis was quantified by flow cytometry (FCM)...

Clostridium perfringens uses its large arsenal of protein toxins to produce histotoxic, neurologic and intestinal infections in humans and animals. The major toxins involved in diseases are alpha (CPA), beta (CPB), epsilon (ETX), iota (ITX), enterotoxin (CPE), and necrotic B-like (NetB) toxins. CPA is the main virulence factor involved in gas gangrene in humans, whereas its role in animal diseases is limited and controversial. CPB is responsible for necrotizing enteritis and enterotoxemia, mostly in neonatal individuals of many animal species, including humans...

Stroke is one of the most devastating complications of bone fracture, occurring in up to 4% of patients after surgical repair for hip fracture. Bone fracture and ischemic stroke have many common risk factors. The impact of bone fracture on stroke recovery has not drawn much attention in the research field. Bone fracture could occur in stroke patients at different times during the recovery phase, which steepens the trajectory of cognitive decline, greatly affects the quality of life, and causes a heavy burden on healthcare resources...

After the birth various physical, hormonal and psychological changes affect women's emotional status. These significantly impact their family life including the quality of sexual relationships. Among these factors the method of birth, hormonal changes, breast feeding and incidence of postpartal depression are considered to affect relations with the partner. Unfortunately the sexuality in this special time in women's life is commonly avoided or underestimated both by woman and doctors.

Helminths are common pathogens of ruminants. These are controlled by anthelmintics; however, resistance is a major issue. More sustainable practices need to be deployed to protect anthelmintic efficacy. There is no published information on how farmer/prescriber interactions at anthelmintic purchase shape application of best practice on-farm. To determine experiences of UK ruminant farmers as they relate to anthelmintic purchasing/provision of best practice advice at the point-of-sale, an online survey was distributed...

Glioblastoma (GBM), the most severe and common brain tumor in adults, is characterized by multiple somatic mutations and aberrant activation of inflammatory responses. Immune cell infiltration and subsequent inflammation cause tumor growth and resistance to therapy. Somatic loss-of-function mutations in the gene encoding tumor suppressor protein p53 (TP53) are frequently observed in various cancers. However, numerous studies suggest that TP53 regulates malignant phenotypes by gain-of-function (GOF) mutations...

Carotid arterial diameter enlargement is a manifestation of arterial remodeling and may be a risk factor for cardiovascular disease (CVD). We evaluated the association between carotid artery diameter and risk of stroke, coronary heart disease, CVD, and all-cause mortality and explored whether the associations could be explained by processes involved in arterial remodeling, that is, blood pressure-related media thickening, arterial stiffness, arterial wall stress, and atherosclerosis. We included 4887 participants (mean age 67±9 years; 54% women) from 4 cohort studies: Rotterdam Study, NEPHROTEST, Hoorn Study, and a study by Blacher et al...

Renal cancer is a common urologic malignancy. However, the therapeutic options for metastatic renal cancer patients are limited. Hypoxia (low oxygen) is a fundamental microenvironmental determinant of solid tumor pathophysiology. Recent data from molecular and clinical studies indicate that hypoxia-inducible factors (HIFs) play critical roles in the development and progress of renal cell carcinoma (RCC). The HIF transcription factor family is a type of heterodimeric transcription factor consisting of HIF-α and HIF-β subunits and can transcriptionally activate genes that mediate the hypoxic response...

Inflammation of the mammary gland following bacterial infection, commonly known as mastitis, affects all mammalian species. Although the aetiology and epidemiology of mastitis in the dairy cow are well described, the genetic factors mediating resistance to mammary gland infection are not well known, due in part to the difficulty in obtaining robust phenotypic information from sufficiently large numbers of individuals. To address this problem, an experimental mammary gland infection experiment was undertaken, using a Friesian-Jersey cross breed F2 herd...

Despite the continuous improvement of pediatric palliative care, medical professionals still face various barriers regarding its implementation; our aim was to investigate this question in Hungarian pediatric oncology practice. Structured interviews were carried out in person with physicians from the Hungarian Pediatric Oncology Group (n = 22). Codes were generated inductively with the aid of Atlas.ti 6.0 software. Most physicians placed the palliative care discussion at the end of curative treatment (n = 21) and preferred to conduct it in a team setting (n = 18), mainly in the presence of a psychologist...
