#1
K S Sullivan, G F Erf
Phytohemagglutinin (PHA) is commonly used to evaluate cell-mediated immunocompetence. In chickens, PHA is typically injected intra-dermally (i.d.) into the skin (e.g., wing web, wattle, or footpad), and the tissue swelling response is monitored, whereby the extent of tissue swelling positively relates to the individual's cell-mediated immune system capabilities. Although i.d. injected PHA was shown to stimulate mononuclear cell and basophil infiltration to the site of injection, reports on temporal, qualitative, and quantitative aspects of the local cutaneous PHA response are limited...

Significant sex differences exist in the activity of the hypothalamic-pituitary-adrenal (HPA) axis. These differences are thought to contribute to the disparity in the prevalence of various autoimmune and infectious diseases between males and females. We use a mathematical model of the HPA axis to evaluate the hypothesis that differential sensitivity and negative feedback of the HPA axis network are causal factors for the observed sex differences in its activity. In doing so, we implicitly account for the differential influence of gonadal hormones on the HPA axis...

OBJECTIVES: Osteogenic protein-1 (OP-1) has shown osteoinductive activities and is useful for clinical treatments, including bone regeneration. Regenerative procedures using a bioabsorbable collagen membrane (BCM) are well established in periodontal and implant dentistry. We evaluated the subsequent effects of the BCM in combination with OP-1 on bone regeneration in a rat mandibular circular critical-sized bone defect in vivo. DESIGN: We used 8 rats that received surgery in both sides of the mandible, and created the total 16 defects which were divided into 4 groups: Group 1; no treatment, as a control, Group 2; BCM alone, Group 3; BCM containing low dose 0...

REVIEW
Virginia Jones, Marie Crowe
BACKGROUND: The increasing prevalence of diabetes is well-documented along with the findings that some ethnic minorities have a higher prevalence than non-minority individuals. Along with possible biological differences between ethnicities, access to economic, social, cultural and symbolic capital may impact on the success of managing type-2 diabetes. OBJECTIVES: To examine how people from ethnic minorities in Western countries describe their experiences of managing type-2 diabetes mellitus...

BACKGROUND: Pain is a frequently reported symptom by patients approaching the end of life and well-established that patients and carers hold fears relating to opioids, and experience side effects related to their use. The management of medicines is intrinsic to achieving effective pain relief. The concept of self-management support whilst well characterised in the context of chronic illness has not been elaborated with respect to end of life care. AIM: To identify patient, carer and professional views on the concept of self-management support at end of life, specifically in relation to analgesia and related medicines (for side-effect management) in order to describe, characterise and explain self-management support in this context...

Research documents significant gender-based salary inequities among physicians and ongoing inadequacies in recruitment and promotion of physicians from underrepresented minority groups. Given the complexity of the social forces that promote these disparities, their elimination will likely require quantitative and qualitative research to understand the pathways that lead to them and to develop effective solutions. Interventions to combat implicit bias will be required, and structural interventions that hold medical school leadership accountable are needed to achieve and maintain salary equity and racial and gender diversity at all levels...

Biological organisms are complex open dissipative systems whose dynamical stability is sustained due to the exchange of matter, energy and information. Dynamical stability occurs through a number of mechanisms that sustain efficient adaptive dynamics. Such properties of living matter can be the consequence of a self-consistent state of matter and electromagnetic field (EMF). Based on the soliton model of charge transport in redox processes, we describe a possible mechanism of the origin of endogenous EMF and coherence...

Eric Alan Eager, Diana Pilson, Helen M Alexander, Brigitte Tenhumberg
Biological populations are strongly influenced by random variations in their environment, which are often autocorrelated in time. For disturbance specialist plant populations, the frequency and intensity of environmental stochasticity (via disturbances) can drive the qualitative nature of their population dynamics. In this article, we extended our earlier model to explore the effect of temporally autocorrelated disturbances on population persistence. In our earlier work, we only assumed disturbances were independent and identically distributed in time...
