[EX Q]: Charcot-Marie-Tooth (CMT) disease is a group of inherited peripheral neuropathies associated with mutations or copy number variations in over 70 genes encoding proteins with fundamental roles in the development and function of Schwann cells and peripheral axons. Here, we used iPSC-derived cells to identify common pathophysiological mechanisms in axonal CMT.', 'iPSC lines from patients with two distinct forms of axonal CMT (CMT2A and CMT2E) were differentiated into spinal cord motor neurons and used to study axonal structure and function and electrophysiological properties in vitro.', 'iPSC-derived motor neurons exhibited gene and protein expression, ultrastructural and electrophysiological features of mature primary spinal cord motor neurons. Cytoskeletal abnormalities were found in neurons from a CMT2E (NEFL) patient and corroborated by a mouse model of the same NEFL point mutation. Abnormalities in mitochondrial trafficking were found in neurons derived from this patient, but were only mildly present in neurons from a CMT2A (MFN2) patient. Novel electrophysiological abnormalities, including reduced action potential threshold and abnormal channel current properties were observed in motor neurons derived from both of these patients.

[EX Q]: To become a parent is an emotionally life-changing experience. Paternal depression during the postnatal period has been associated with emotional and behavioral problems in children. The condition has predominantly been related to mothers, and the recognition of paternal postnatal depression (PND) has been paid less attention to. PND in fathers may be difficult to detect. However, nurses in pediatric services meet a lot of fathers and are in a position to detect a father who is suffering from PND. Therefore, the aim of this study was (a) to explore Child Health Center nurses' experiences of observing depression in fathers during the postnatal period; and (b) to explore hindrances of observing these fathers.", 'A qualitative descriptive study was conducted. Ten nurses were interviewed in 2014. A thematic data analysis was performed and data were analyzed for meaning.', 'Paternal PND was experienced as being vague and difficult to detect. Experiences of fathers with such problems were limited, and it was hard to grasp the health status of the fathers, something which was further complicated when routines were lacking or when gender attitudes influenced the daily work of the nurses.

[EX Q]: Although Kupffer cells (KCs) are capable of producing important growth-stimulating cytokines, their role in liver regeneration following partial hepatectomy (PH) remains poorly understood.', 'In the present study liver regeneration was studied after KC-depletion by intravenous administration of liposome-encapsulated dichloromethylene-diphosphonate (C12MDP), a method known to physically eliminate KCs. Furthermore, splenectomy was performed one week prior to PH to exclude the effect of C12MDP-liposomes on macrophage populations in the spleen.', 'KC-depletion was confirmed in cryostat liver sections stained with the monoclonal antibody ED2, a marker for resident tissue macrophages. Forty-eight hours after PH, the cumulative hepatocyte DNA synthesis, as determined in liver sections by the hepatocyte bromodeoxyuridine labeling index, was significantly decreased in KC-depleted rats when compared to control-rats. The weight of the remnant liver, expressed as a percentage of the initial liver weight, was significantly less at 96 h after PH in KC-depleted rats. KC-depletion abolished the hepatic interleukin-6 (IL-6) and interleukin-10 (IL-10) mRNA synthesis and decreased hepatic expression of tumor necrosis factor-alpha (TNF-alpha), hepatocyte growth factor (HGF) and transforming growth factor-beta1(TGF-beta1) mRNA after PH, as was assessed by reverse-transcriptase polymerase chain reaction (RT-PCR). Moreover, at 4 h after PH the systemic release of IL-6 was significantly decreased in KC-depleted rats.
