AIM: National and international healthcare agencies and organizations typically attribute slow or haphazard growth in hospice and palliative care in developing countries to various resource constraints. This study provides evidence of the substantial and widening gap between policy advocacy and individual decision-making concerning end-of-life care. It does so by establishing the incentives and risks that underlie choices of patients and providers against the relative scarcity of hospices in these countries...

Sexuality is presumptively and observably a powerful core element of the human pair-bond relationship. Technological advances of the last half-century have made media a dominant cultural and developmental presence, including scripting sexual relationship attitudes and behavior. Theoretically and empirically, we examine loneliness as it relates to pornography use in terms of pornography's relational scripting and its addictive potential. Empirically, we examine the associative nature between pornography use and loneliness using a measurement model and two structural equation models where pornography use and loneliness are regressed on each other, respectively...

Periodontal ligament fibroblasts (PDLFs) are important cells, which are involved in maintaining tooth integrity. Diabetes has been found to be associated with periodontal disease in a bidirectional manner. The aim of the present study was to investigate the stemness properties of human PDLFs (HPDLFs) in high glucose conditions. HPDLFs were analyzed for their osteogenic differentiation capacity by inducing the cells with osteogenic medium in various glucose concentrations. The gene expression was then examined using reverse transcription‑quantitative polymerase chain reaction analysis, and examinations of alkaline phosphatase activity and nodule formation were performed...

Fifteen D. hansenii strains from different food origins were genetically characterised and tested on a culture medium resembling the composition of fermented sausages but different concentrations of nitrifying preservatives. Genetic typing of the D. hansenii strains revealed two levels of discrimination, isolation source or strain specific. Different ability to proliferate on culture media containing different concentrations of nitrate and nitrite, as sole nitrogen sources and in presence of amino acids, was observed within D...

Okara is a nutritionally valuable by-product produced in large quantities as result of soymilk elaboration. This work proposes its use as both culture and dehydration medium during freeze-drying, spray-drying, and storage of Lactobacillus plantarum CIDCA 83114. Whole and defatted okara were employed as culture media for L. plantarum CIDCA 83114. The growth kinetics were followed by plate counting and compared with those of bacteria grown in MRS broth (control). No significant differences in plate counting were observed in the three media...

Livestock, having close resemblance to humans, could be a better source of primary hepatocytes than rodents. Herein, we successfully developed three-dimensional (3D) culturing system for primary sheep and buffalo hepatocytes. The 3D-structures of sheep hepatocytes were formed on the fifth-day and maintained until the tenth-day on polyHEMA-coated plates and in hanging drops with William's E media (HDW). Between the cultured and fresh cells, we observed a similar expression of GAPDH, HNF4α, ALB, CYP1A1, CK8 and CK18...

BACKGROUND: Cell-assisted lipotransfer has been promisingly applied to restore soft-tissue defects in plastic surgery; however, the harvesting of stromal vascular fraction increases morbidity and poses potential safety hazards. The authors investigated whether adding indomethacin, an antiinflammatory proadipogenic drug, to the fat graft at the time of transplantation would enhance the final graft volume compared with cell-assisted lipotransfer. METHODS: In vitro, human adipose-derived stem cells were cultured in conditioned growth media supplemented with various doses of indomethacin to investigate adipogenesis and the expression of the adipogenic genes...

An efficient regeneration system through somatic embryogenesis was developed for date palm cv. Najda. Adventitious bud and proximal leaf segments cultured on Murashige and Skoog (MS) medium supplemented with various combinations of auxins and cytokinins induced embryogenesis after at least 6 months of culture. Somatic embryogenesis induction seemed correlated with the type of the explant, the induction period and the auxin used. The highest rate of somatic embryogenesis (86.0%) was obtained on bud explants cultured on MS medium supplemented with 45...

"The Methods of Clinical Laboratory" was the first comprehensive Romanian book in the medical laboratory field, having utility in clinical practice. It was written by Prof. Ioan Manta (1900-1979) and Alexandru Ciplea (1912-1988), both from the Cluj Faculty of Medicine. The volume was published for the first time in 1944, during the refuge of this Faculty in Sibiu, and for the second time in 1947, in Cluj. Our aim is to make a brief analysis of its structure and to put into evidence the importance of this book for the Romanian laboratory medicine, some techniques (e...

Kwabena O Duedu, Christopher E French
Estimation of bacterial growth by rapid traditional methods such as spectrophometric measurements at 600 nm (OD600) is not applicable for cultures containing insoluble particles in the growth media. Colony counts are the only suitable alternative but these are laborious and not high-throughput. The data presented in this article is related to the research article entitled "Two-colour fluorescence fluorimetric analysis for direct quantification of bacteria and its application in monitoring bacterial growth in cellulose degradation systems" (Duedu and French, 2017) [1]...

REVIEW
Yvan Caspar, Max Maurin
The antibiotic classes that are recommended for tularaemia treatment are the aminoglycosides, the fluoroquinolones and the tetracyclines. However, cure rates vary between 60 and 100% depending on the antibiotic used, the time to appropriate antibiotic therapy setup and its duration, and the presence of complications, such as lymph node suppuration. Thus, antibiotic susceptibility testing (AST) of F. tularensis strains remains of primary importance for detection of the emergence of antibiotic resistances to first-line drugs, and to test new therapeutic alternatives...

Lignocellulosic biomass is a vast and underutilized resource for the production of sugars and biofuels. However, the structural complexity of lignocellulosic biomass and the need for multiple pretreatment and enzymatic steps for sugar release renders this process economically challenging. Here, we report a novel approach for direct, single container, exogenous enzyme-free conversion of lignocellulosic biomass to sugars and biofuels using the anaerobic fungal isolate strain C1A. This approach utilizes simple physiological manipulations for timely inhibition and uncoupling of saccharolytic and fermentative capabilities of strain C1A, leading to the accumulation of sugar monomers (glucose and xylose) in the culture medium...

Background: An appropriate intake of omega-3 (n-3) fatty acids (FAs) such as eicosapentaenoic and docosahexaenoic acid (EPA/DHA) from marine sources is known to have anti-inflammatory effects. However, molecular mechanisms underlying their beneficial effects on health are not fully understood. The aim of the present study was to characterize gene expression profiles of THP-1 macrophages, incubated in either EPA or DHA and stimulated with lipopolysaccharide (LPS), a pro-inflammatory agent. Methods: THP-1 macrophages were incubated into 10, 50 and 75 µM of EPA or DHA for 24 h, and 100 nM of LPS was added to the culture media for 18 h...

Melanoma, an extremely aggressive cancer, causes the most skin cancer-related deaths, due to metastasis to other areas of the body, such as lymph nodes, lungs, liver, brain or bone. It is characterized by high levels of matrix metalloproteinase (MMP)-2 and -9 secretions that degrade the extracellular matrix and basement membrane, allowing cancer cells to spread to distal organs. Various cytokines, mitogens, growth factors, inducers and inhibitors control MMP activities. We investigated the roles of these in regulation of MMP-2 and -9 in human melanoma A-2058 cells...

This commentary expands on Anderson, Bushman, Donnerstein, Hummer, and Warburton's agenda for minimizing the impacts of violent media exposure (VME) on youth aggression. We argue that in order to effectively intervene in the development of aggression and other maladaptive traits, researchers and policymakers should take an ecological, developmental psychopathology approach to understanding children's exposure to VME within developmental, relational, environmental, and cultural contexts. Such a framework holds the most promise for identifying at-risk groups, establishing targets of intervention, and testing mechanisms of change...

Piscirickettsia salmonis is the etiological agent of piscirickettsiosis, which, as the main systemic disease in the Chilean salmon industry, causes significant economic losses. This bacterium can produce biofilm as a persistence and survival strategy in adverse conditions. In other bacteria, cheA is a key gene for modulating the onset of bacterial chemotaxis, as well as having a secondary role in biofilm production. Notwithstanding this association, the potential relationships between biofilm formation and genes involved in P...

DNA methylation is a biochemical process that modifies gene expression without changing the underlying DNA sequence, and this represents the molecular basis for imprinting and epigenetics. Recent reports have revealed alterations in DNA methylation profiles in the placenta of babies born from assisted reproductive technologies (ART). This supports several previous observations that suggested an increase in the prevalence of imprinting diseases following ART treatment, and also fits our observations regarding the metabolism and requirements of early human embryos...
