Aim Shigella species has varying levels of virulence gene expression with respect to different sites of infection. In this study, the differential gene expression of S. dysenteriae in response to its site of infection was analyzed by transcriptomics. Methods This study includes four clinical Shigella isolates. Transcriptomics was done for the stool and blood samples of a single patient. Isolates were screened for the presence of antimicrobial resistance genes. Results The majority of genes involved in invasion were highly expressed in the strain isolated from the primary site of infection. Additionally, antimicrobial resistance (dhfr1A, sulII, bla OXA. bla CTX-M-1 and qnrS) genes were identified. Conclusion This study provides a concise view of the transcriptional expression of clinical strains and provides a basis for future functional studies on Shigella spp. © 2020 Balaji Veeraraghavan.The prevalence of oncogenic rat sarcoma virus (RAS) mutations has made RAS a popular target for cancer therapies. Significant discoveries have been reported regarding cancer molecular biology following the study of RAS mutations. These discoveries are integral in shaping the era of targeted cancer therapy, with direct targeting of RAS or downstream RAS effectors, such as Grb2 and MAPK a possibility. Novel agents such as farnesyltransferase directly bind and sequester RAS. While these new agents and approaches have shown promise in preclinical and clinical studies, the complexity of RAS signaling and the potential for robust adaptive feedback continue to present substantial challenges. Therefore, the development of targeted therapies will require a detailed understanding of the properties and dependencies of specific cancers to a RAS mutation. This review provides an overview of RAS mutations and their relationship with cancer and discusses their potential as therapeutic targets. © 2020 Sanjana Murdande.Over the last two decades, the pig population in Africa has grown rapidly, reflecting the increased adoption of pig production as an important economic activity. Of all species, pigs are likely to constitute a greater share of the growth in the livestock subsector. However, constraints such as respiratory infectious diseases cause significant economic losses to the pig industry worldwide. Compared to industrialized countries, the occurrence and impacts of respiratory diseases on pig production in Africa is under-documented. Hence, knowledge on prevalence and incidence of economically important swine respiratory pathogens in pigs in Africa is necessary to guide interventions for prevention and control. The purpose of this review was to document the current status of research on five important respiratory pathogens of swine in Africa to inform future research and interventions. The pathogens included were porcine reproductive and respiratory syndrome virus (PPRSv), porcine circovirus 2 (PCV2), Mycoplasma hyopneine in Africa, which calls for further studies.

Digital technology may serve as a cost-effective and scalable platform to deliver such an intervention. This study describes the iterative development of a theory-based, digital behaviour change intervention to reduce occupational SB. Methods The behaviour change wheel and The Behaviour Change Technique Taxonomy were used to guide the intervention design process and form a basis for selecting the intervention components. The development process consisted of four phases phase 1 - preliminary research, phase 2 - consensus workshops, phase 3 - white boarding and phase 4 - usability testing. Results The process led to the development and refinement of a smartphone application - Worktivity. The core component was self-monitoring and feedback of SB at work, complemented by additional features focusing on goal setting, prompts and reminders to break up prolonged periods of sitting, and educational facts and tips. Key features of the app included simple data entry and personalisation based on each individual's self-reported sitting time. Results from the 'think-aloud' interviews (n=5) suggest Worktivity was well accepted and that users were positive about its features. Conclusion This study led to the development of Worktivity, a theory-based and user-informed mobile app intervention to reduce occupational SB. It is the first app of its kind developed with the primary aim of reducing occupational SB using digital self-monitoring. This paper provides a template to guide others in the development and evaluation of technology-supported behaviour change interventions. © The Author(s) 2020.Background Because cisplatin (CDDP) decreases upon light exposure, it is necessary to prevent such exposure during administration. However, the shielding conditions employed are not uniform. Therefore, in this study, we examined the shielding effects of four shading covers, which are commonly used to ensure the stability of CDDP in clinical settings. Methods Four shielding conditions, along with a control, were tested under a 1000-Lux white fluorescent lamp at room temperature aluminum foil (Al), brown shading cover (BSC), yellow shading cover (YSC), milky-white anti-exposure cover (MAC), and no shading cover (NSC). Under each shielding condition, the relationship between the wavelength and transmittance was monitored in the range of 200-800 nm. CDDP was diluted to three concentration levels 50, 100, and 250 μg/mL. Furthermore, the amount of remaining CDDP and the pH in the solutions were measured for 120 h. Results We found that BSC, YSC, and MAC conditions allowed various levels of transmittance; however, Ats the decrease in CDDP under fluorescent lighting, potentially contributing to achieving its full therapeutic effect. © The Author(s) 2020.Background Vitamin B12 deficiency causes a number of neurological features including cognitive and psychiatric disturbances, gait instability, neuropathy, and autonomic dysfunction. Clinical recognition of B12 deficiency in neurodegenerative disorders is more challenging because it causes defects that overlap with expected disease progression. We sought to determine whether B12 levels at the time of diagnosis in patients with Parkinson's disease (PD) differed from those in patients with other neurodegenerative disorders. Methods We performed a cross-sectional analysis of B12 levels obtained around the time of diagnosis in patients with PD, Multiple System Atrophy (MSA), Dementia with Lewy Bodies (DLB), Alzheimer's disease (AD), Progressive Supranuclear Palsy (PSP), Frontotemporal Dementia (FTD), or Mild Cognitive Impairment (MCI). We also evaluated the rate of B12 decline in PD, AD, and MCI. Results In multivariable analysis adjusted for age, sex, and B12 supplementation, we found that B12 levels were significantly lower at time of diagnosis in patients with PD than in patients with PSP, FTD, and DLB. In PD, AD, and MCI, the rate of B12 decline ranged from - 17 to - 47 pg/ml/year, much greater than that reported for the elderly population. Conclusions Further studies are needed to determine whether comorbid B12 deficiency affects progression of these disorders. © The Author(s) 2020.Little is actually known about the nature and characteristics of the cognitive dissonance state. In this paper, we review the actual knowledge and the main limitations of past studies. Then, we present two studies that investigate the characteristics of the cognitive dissonance state from the perspective the Pleasure Arousal Dominance model of emotion. Study 1 (N = 102) used the hypocrisy paradigm and Study 2 (N = 130) used a counterattitudinal essay. In Study 1, participants in the Dissonance condition reported less Pleasure with each inconsistent behaviour remembered. In Study 2, participants in the Dissonance condition reported less Pleasure than participants in the Control Condition. In both studies, no significant difference was found on the Arousal and Dominance indexes. These results are among the first to link cognitive dissonance to a general model of emotions, an approach that should be pursued further.

The aim is not just to obtain a surface which has a desired intrinsic Riemannian metric, but to get the desired embedding in R 3 up to translations and rotations. In this paper, we demonstrate three generic methods of moulding a flat sheet of thermo-responsive plastic by selective contraction induced by targeted heating. These methods do not involve any cutting and gluing, which is a property they share with origami. The first method is inspired by tailoring, which is the usual method for making garments out of plain pieces of cloth. Unlike usual tailoring, this method produces the desired embedding in R 3 . The second method just aims to bring about the desired new Riemannian metric via an appropriate pattern of local contractions, without directly controlling the embedding. The third method is based on triangulation, and seeks to induce the desired local distances. This results in getting the desired embedding in R 3 . The second and the third methods, and also the first method for the special case of surfaces of revolution, are algorithmic in nature. We explain these methods and show examples. © 2020 The Authors.Synergistic and antagonistic interactions in multi-species populations-such as resource sharing and competition-result in remarkably diverse behaviours in populations of interacting cells, such as in soil or human microbiomes, or clonal competition in cancer. The degree of inter- and intra-specific interaction can often be quantified through the notion of an ecological 'niche'. Typically, weakly interacting species that occupy largely distinct niches result in stable mixed populations, while strong interactions and competition for the same niche result in rapid extinctions of some species and fixations of others. We investigate the transition of a deterministically stable mixed population to a stochasticity-induced fixation as a function of the niche overlap between the two species. We also investigate the effect of the niche overlap on the population stability with respect to external invasions. Our results have important implications for a number of experimental systems. © 2020 The Authors.Sexual reproduction is not always synonymous with the existence of two morphologically different sexes; isogamous species produce sex cells of equal size, typically falling into multiple distinct self-incompatible classes, termed mating types. A long-standing open question in evolutionary biology is what governs the number of these mating types across species? Simple theoretical arguments imply an advantage to rare types, suggesting the number of types should grow consistently; however, empirical observations are very different. While some isogamous species exhibit thousands of mating types, such species are exceedingly rare, and most have fewer than 10. In this paper, we present a mathematical analysis to quantify the role of fitness variation-characterized by different mortality rates-in determining the number of mating types emerging in simple evolutionary models. We predict that the number of mating types decreases as the variance of mortality increases. © 2020 The Authors.
