[EX Q]: Paragraph: Daily oscillations of pulmonary function depend on the rhythmic activity of the circadian timing system. Environmental tobacco/cigarette smoke (CS) disrupts circadian clock leading to enhanced inflammatory responses. Infection with influenza A virus (IAV) increases hospitalization rates and death in susceptible individuals, including patients with Chronic Obstructive Pulmonary Disease (COPD). We hypothesized that molecular clock disruption is enhanced by IAV infection, altering cellular and lung function, leading to severity in airway disease phenotypes. C57BL/6J mice exposed to chronic CS, BMAL1 knockout (KO) mice and wild-type littermates were infected with IAV. Following infection, we measured diurnal rhythms of clock gene expression in the lung, locomotor activity, pulmonary function, inflammatory, pro-fibrotic and emphysematous responses. Chronic CS exposure combined with IAV infection altered the timing of clock gene expression and reduced locomotor activity in parallel with increased lung inflammation, disrupted rhythms of pulmonary function, and emphysema. BMAL1 KO mice infected with IAV showed pronounced detriments in behavior and survival, and increased lung inflammatory and pro-fibrotic responses. This suggests that remodeling of lung clock function following IAV infection alters clock-dependent gene expression and normal rhythms of lung function, enhanced emphysematous and injurious responses. This may have implications for the pathobiology of respiratory virus-induced airway disease severity and exacerbations. I nfluenza virus, rhinovirus, coronavirus, respiratory syncytial virus, parainfluenza, adenovirus and metapeumovirus are among the respiratory viruses known to cause exacerbations in Chronic Obstructive Pulmonary Disease (COPD) and asthma 1-4 . In fact, respiratory viral infections account for about 50-70% of acute exacerbations in patients with COPD 5 . COPD exacerbations are often followed by subsequent clinical pulmonary deterioration, including significant declines in forced expiratory volume at 1 second (FEV 1 ) and increased hospitalization or mortality 6 . This is associated with worsening of COPD phenotypes, such as cough, fever and mucus production; the timing of which depends on the activity of the biological clock. Circadian rhythms are biological oscillations that occur with a near-24-h period and are synchronized or entrained to environmental cues, such as the day-night cycle 7 . These rhythms are the manifestation of an autoregulatory molecular oscillator of interlocked positive and negative transcription factors collectively referred to as clock genes 8 . In mammals, the central pacemaker, localized to the suprachiasmatic nucleus (SCN) of the anterior hypothalamus, drives rhythms of physiology and behavior, and synchronizes internal timing with the external environment 7 . Apart from the central clock, peripheral tissues such as the liver, heart and the lung also contain autonomous circadian oscillators that coordinate tissue specific cellular functions and responses to environmental stimuli 7-12 . As an example, circadian rhythms in pulmonary function have been demonstrated in animal models and healthy individuals (highest at noon time and low during the early morning hours) [13] [14] [15] . The coordinated and synchronized activity of central and peripheral oscillators is referred to as the circadian timing system 9,12 . It has been shown that recruitment of leukocytes to tissues following infection is also regulated by the circadian timing system 16, 17 . For example, macrophages and mast cells exhibit robust rhythms of circadian clock and proinflammatory cytokine gene expression 18, 19 . The magnitude of immune and inflammatory parameters varies with time of day, and disruption of circadian rhythms (chronodisruption) has been implicated in cellular dysfunction, and in the pathogenesis of chronic metabolic disease, infection, and inflammatory diseases 20-22 .

[EX Q]: Paragraph: Perinatal death (PD) is a devastating obstetric complication. Determination of cause of death helps in understanding why and how it occurs, and it is an indispensable aid to parents wanting to understand why their baby died and to determine the recurrence risk and management in subsequent pregnancy. Consequently, a perinatal death requires adequate diagnostic investigation. An important first step in the analysis of PD is to identify the case circumstances, including relevant details regarding maternal history, obstetric history and current pregnancy (complications are evaluated and recorded). In the next step, placental examination is suggested in all cases, together with molecular cytogenetic evaluation and fetal autopsy. Investigation for fetalematernal hemorrhage by Kleihauer is also recommended as standard. In cases where parents do not consent to autopsy, alternative approaches such as minimally invasive postmortem examination, postmortem magnetic resonance imaging, and fetal photographs are good alternatives. After all investigations have been performed it is important to combine findings from the clinical review and investigations together, to identify the most probable cause of death and counsel the parents regarding their loss.

[EX Q]: Paragraph: Macrophage colony-stimulating factor (CSF1) is an essential growth and differentiation factor for cells of the macrophage lineage. To explore the role of CSF1 in steady-state control of monocyte production and differentiation and tissue repair, we previously developed a bioactive protein with a longer half-life in circulation by fusing pig CSF1 with the Fc region of pig IgG1a. CSF1-Fc administration to pigs expanded progenitor pools in the marrow and selectively increased monocyte numbers and their expression of the maturation marker CD163. There was a rapid increase in the size of the liver, and extensive proliferation of hepatocytes associated with increased macrophage infiltration. Despite the large influx of macrophages, there was no evidence of liver injury and no increase in circulating liver enzymes. Microarray expression profiling of livers identified increased expression of macrophage markers, i.e., cytokines such as TNF, IL1, and IL6 known to influence hepatocyte proliferation, alongside cell cycle genes. The analysis also revealed selective enrichment of genes associated with portal, as opposed to centrilobular regions, as seen in hepatic regeneration. Combined with earlier data from the mouse, this study supports the existence of a CSF1-dependent feedback loop, linking macrophages of the liver with bone marrow and blood monocytes, to mediate homeostatic control of the size of the liver. The results also provide evidence of safety and efficacy for possible clinical applications of CSF1-Fc. hepatosplenomegaly; CD163; macrophages; hepatostat; M-CSF This study is based on extensive studies in the mouse of the role of CSF1 in monocyte-macrophage production and differentiation and the function of macrophages in the control of hepatocyte proliferation. We use a novel form of CSF1, an Fc fusion protein, to demonstrate that the findings in mice can be extended to large animals. We discuss the possible role for CSF1 in homeostatic control of the size of the liver. MACROPHAGE COLONY-STIMULATING FACTOR (CSF1) is an essential growth and differentiation factor for cells of the macrophage lineage (23). Subsequent to the original isolation of human CSF1 cDNA in the 1980s and demonstration that injection of the recombinant CSF1 protein can expand macrophage popu-* K. A. Sauter and L. A.
