Background: Phylogenetic analysis shows that Pneumocystis have coevolved with their mammalian hosts for millions of years. As a result, infection by Pneumocystis is species specific (i.e. a given Pneumocystis species can infect only a single species of host). This specificity suggests the existence of a Red-Queen dynamic between Pneumocystis and its host. Evidence of this dynamic is provided by the molecular diversity and the elevated rate of non-synonymous versus synonymous (dN/dS) codon substitutions among Pneumo [...]

Elevated levels of psychological distress in university students is a growing area of concern as it is associated with a variety of consequences including mental illness symptoms, absenteeism, and poor academic performance. A growing body of research has indicated that resilience in university students is associated with reduced psychological distress and perceived stress. The construct of resilience and the factors that contribute to its development are not well understood, hampering the development of effective i [...]

Objectives: The purpose of this systematic literature review is to investigate the impact of case management on the link between HIV/AIDS patients (HIV-infected persons) and HIV treatment, and to investigate the impact of case management on their morbidity and mortality. Methods: We searched PubMed, Current Contents, Scopus, EMBASE, MEDLINE, the Effect Review Summary Database and the ACP Journal Club until May 2018. A randomized clinical trial examined the impact of case management on the association of PLHA with c [...]

Hybrid composites based on inorganic nanomaterials embedded into a polymer matrix have were synthesized and characterized. Oxide semiconductor nanoparticles (SnO, SnO2, TiO2, Ga2O3, and NiO) and Si nanoparticles were employed as inorganic counterparts in the hybrid composite, while a conductive polymer (PEDOT:PSS) with diverse additives was used as the organic matrix. The composites were spin-coated on Si or glass substrates. The potential use of these materials in photovoltaic devices to improve Si surface passiva [...]

Gene-engineered animals created using gene-targeting technology have long been recognized as beneficial, valid, and valuable tools for exploring the function of a gene of interest, at least in early 2013. This approach, however, suffers from laborious and time-consuming tasks, such as the production of successfully targeted embryonic stem (ES) cells, their characterization, production of chimeric blastocysts carrying these gene-modified ES cells, and transplantation of those manipulated blastocysts to the recipient [...]

Due to recent global warming and climate change events, about 127 countries have declared themselves carbon neutral since the Paris Agreement was signed. Furthermore, agriculture is directly or indirectly affected by climate change. In particular, the importance of carbon neutrality is very high due to the high carbon absorption potential of forestry biomass. In the global beverage market, green tea is the second most consumed beverage after water, and the potential of tea tree biomass to absorb carbon during culti [...]

Relationships between nature connection, mindfulness and wellbeing have been observed through nature based therapeutic interventions, where mindfulness and nature appear to reciprocally influence each other in relation to wellbeing and is potentially consistent with attention restoration theory. However, previous studies have relied on examining nature based interventions rather than the role of nature connection in everyday lives. This investigation explored the relationship between nature connection, mindfulness, [...]

The study aimed to evaluate the efficacy of various bioremediation approaches on microbial diversity in crude oil-contaminated soil over three to six months in Port Harcourt, Nigeria. The objective was to assess the impact of different bioremediation strategies on microbial populations, particularly focusing on hydrocarbon-utilizing bacteria and fungi. Microbial populations were quantified using serial dilution and microbial count techniques. The vapor phase transfer mechanism was employed to estimate hydrocarbon-u [...]

Background: Sport-related concussion is a growing public health concern. Defined as a injury that disturbs neurological functions, concussion is characterised by a constellation of signs and symptoms. However, clinical imaging methods do not reveal any structural damage. Recently, neurophysiological techniques such as single and paired-pulse transcranial magnetic stimulation (TMS) are being applied to quantify neurophysiological changes (specifically corticospinal and intracortical excitation and intracortical inhi [...]
