BACKGROUND: Hypothyroidism may complicate allogeneic hematopoietic stem cell transplantation (allo-HSCT); we therefore analyzed risk factors in this study. PATIENTS AND METHODS: We studied 229 patients with acute myeloid leukemia (AML) who underwent an allo-HSCT between 2003 and 2013 with different conditioning regimens (myeloablative, reduced-intensity, chemotherapy-based, or total body irradiation-based). Thyroid-stimulating hormone (TSH) and free thyroxine levels (fT4) were available in 104 patients before and after allo-HSCT...

Exercise represents an energetic challenge to whole-body homeostasis. In skeletal muscle, exercise activates a variety of signaling pathways that culminate in the nucleus to regulate genes involved in metabolism and contractility; however, much remains to be learned about the transcriptional effectors of exercise. Mediator is a multiprotein complex that links signal-dependent transcription factors and other transcriptional regulators with the basal transcriptional machinery, thereby serving as a transcriptional "hub...

First discovered in unicellular eukaryotes, centrins play crucial roles in basal body duplication and anchoring mechanisms. While the evolutionary status of the founding members of the family, Centrin2/Vfl2 and Centrin3/cdc31 has long been investigated, the evolutionary origin of other members of the family has received less attention. Using a phylogeny of ciliate centrins, we identify two other centrin families, the ciliary centrins and the centrins present in the contractile filaments (ICL centrins). In this paper, we carry on the functional analysis of still not well known centrins, the ICL1e subfamily identified in Paramecium, and show their requirement for correct basal body anchoring through interactions with Centrin2 and Centrin3...

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are part of the armamentarium for the treatment of type 2 diabetes (T2D), although recent guidelines have mainly recommended their use on top of oral treatments when a single or combination of two or three oral hypoglycaemic agents has failed to lower HbA1c levels below the individualized target range. In such situations, the decision to use GLP-1RAs is mostly driven by their high level of efficacy, their effect on body weight balance and their safety considerations, such as low hypoglycaemic risk...

The patient was a 79-year-old woman who had received enucleation of right pulmonary papilloma 7 years earlier. She experienced bloody sputum and was therefore referred to our hospital. Chest computed tomography revealed a mass shadow(21 mm) in the right upper lobe (S2). By bronchoscopy, there was no bulging lesion in the visible range. SCC and CEA increased to 6.4 ng/ml and 6.42 ng/ml, respectively. Whole-body 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) showed increased FDG uptake in the region of the right-lung mass shadow (maximum standardized uptake value 12...

Proteins localized to the basal body and the centrosome play crucial roles in ciliary assembly and functions. Although RABL2 and CEP19 are conserved in ciliated organisms and have been implicated in ciliary/flagellar functions, their roles were poorly understood. We here showed that RABL2 interacts with CEP19 and is recruited to the mother centriole and basal body in a CEP19-dependent manner, and that CEP19 is recruited to the centriole probably via its binding to the centrosomal protein FGFR1OP. Disruption of the RABL2 gene in Chlamydomonas reinhardtii resulted in the non-flagellated phenotype, suggesting a crucial role of RABL2 in ciliary/flagellar assembly...

Background Interleukin-23 is thought to be critical to the pathogenesis of psoriasis. We compared risankizumab (BI 655066), a humanized IgG1 monoclonal antibody that inhibits interleukin-23 by specifically targeting the p19 subunit and thus prevents interleukin-23 signaling, and ustekinumab, an interleukin-12 and interleukin-23 inhibitor, in patients with moderate-to-severe plaque psoriasis. Methods We randomly assigned a total of 166 patients to receive subcutaneous injections of risankizumab (a single 18-mg dose at week 0 or 90-mg or 180-mg doses at weeks 0, 4, and 16) or ustekinumab (45 or 90 mg, according to body weight, at weeks 0, 4, and 16)...

Basal insulin peglispro (BIL) consists of insulin lispro with a 20-kDa polyethylene glycol (PEG) moiety covalently attached to lysine B28. Because chronic parenteral administration of PEGylated proteins to animals has sometimes resulted in PEG vacuolation of tissue macrophages, renal tubular cells, and choroid plexus ependymal cells, we investigated whether chronic subcutaneous (sc) injection of BIL in rats (52 weeks) and dogs (39 weeks) was associated with systemic toxicities or other changes, including vacuolation of tissue macrophages, renal tubular cells, and ependymal cells...

The objective of this study was to investigate the effects of Bacillus subtilis-based probiotic supplementation in broiler chicken diets on growth performance, feed efficiency, intestinal cytokine, and tight junction (TJ) protein mRNA expression. Zero-day-old broiler chicks (n = 140) were randomly assigned to one of five dietary treatments: basal diet (CON); basal diet supplemented with either antibiotic bacitracin methylene disalicylate (BMD); or probiotics, namely, B. subtilis strain 1781 (PB1), a combination of B...

Intraflagellar transport (IFT) is required for ciliogenesis by ferrying ciliary components using IFT complexes as cargo adaptors. IFT54 is a component of the IFT-B complex and is also associated with cytoplasmic microtubules (MTs). Loss of IFT54 impairs cilia assembly as well as cytoplasmic MT dynamics. The N-terminal calponin homology (CH) domain of IFT54 interacts with tubulins/MTs and has been proposed to transport tubulin during ciliogenesis, whereas the C-terminal coiled-coil (CC) domain binds IFT20. However, the precise function of these domains in vivo is not well understood...

Identifying the location of the dermal epidermal junction (DEJ) in skin images is essential in several clinical applications of dermatology such as epidermal thickness determination in healthy versus unhealthy skins, such as basal cell carcinoma. Optical coherence tomography (OCT) facilitates the visual detection of DEJ in vivo. However, due to the granular texture of speckle and a low contrast between dermis and epidermis, a skin border detection method is required for DEJ localization. Current DEJ algorithms work well for skins with a visible differentiable epidermal layer but not for the skins of different body sites...

INTRODUCTION: Oral contraceptives could induce mood changes. As far as our knowledge, there are no studies in literature that have examined the role of vaginal contraception in self-perceived body image. AIM: To evaluate the effects of intravaginal contraception on weight gain and perceived body image in relation with the Beck's Depression Inventory questionnaire (BDI) and the McCoy Female Sexuality Questionnaire (MFSQ). METHODS: Twenty-one adult (18-35 years old) eumenorrheic (menstrual cycle of 25-35 days), lean (body mass index - BMI - of 19-25 kg/m(2)) women who were referred for hormonal contraception were administered the Stunkard Figure Rating Scale (FRS), BDI and MFSQ...

The primary cilium is nucleated by the mother centriole-derived basal body (BB) via as yet poorly characterized mechanisms. BBs have been reported to degenerate following ciliogenesis in the C. elegans embryo, although neither BB architecture nor early ciliogenesis steps have been described in this organism. In a previous study (Doroquez et al., 2014), we described the three-dimensional morphologies of sensory neuron cilia in adult C. elegans hermaphrodites at high resolution. Here, we use serial section electron microscopy and tomography of staged C...

Cilia are cellular projections that assemble on centriole-derived basal bodies. While cilia assembly is absolutely dependent on centrioles, it is not known to what extent they contribute to downstream events. The nematode C. elegans provides a unique opportunity to address this question, as centrioles do not persist at the base of mature cilia. Using fluorescence microscopy and electron tomography, we find that centrioles degenerate early during ciliogenesis. The transition zone and axoneme are not completely formed at this time, indicating that cilia maturation does not depend on intact centrioles...

Silver nanoparticles (AgNPs) have been increasingly used as antimicrobial and disinfectant. However, intestinal model studies have shown that AgNPs induce oxidative stress. Hence, this study aims to investigate the effects of dietary supplemental zinc (Zn) and vitamin E (VE; α-tocopherol acetate) on attenuating AgNP-induced intestinal oxidative stress in broiler chickens. The chickens were divided into two groups as follows: (1) control group fed with a corn-soybean meal basal diet and (2) nano group, received drinking water containing 1000 mg/kg AgNPs...

The organic anion transporting polypeptide (OATP) 2B1 which is ubiquitously expressed in the human body is assumed to play an important role in the cellular uptake of many drugs. While the expression and function of this SLC transporter is well characterized in the human liver, little is known about its localization and functional relevance in the intestine. Thus, it was the aim of this study to investigate its localization and function in the human jejunum and in the frequently used intestinal Caco-2 cell line...

BACKGROUND: Worsening renal function, indicated by increased serum creatinine (SCr), is a common complication of percutaneous coronary procedures. Risk factors for increased SCr overlap with coronary risk factors involved in endothelial dysfunction. We hypothesized that endothelial dysfunction, measured using the reactive hyperemia peripheral arterial tonometry index (RHI), can predict periprocedure-increased SCr. METHODS: RHI was assessed before elective coronary procedures in 316 consecutive stable patients with a preserved estimated glomerular filtration rate (eGFR, >60mL/min/1...

Acute dilation brought about by the dietary flavonoid quercetin in coronary arterioles has been described earlier, but no information is available on its chronic effects. Male Wistar rats (body weight about 190 g) were divided to two groups: the quercetin-treated group (n=22) had quercetin supplementation of approximately 30 mg/kg/day, whereas the control group (n=20) had none. After eight weeks of treatment, intramural coronary arterioles with identical passive diameters (178+/-14 and 171+/-9 microm) were prepared and their biomechanics and pharmacological reactivities were tested using pressure arteriography ex vivo...
