Effects of Chronotype and Social Jet-Lag on Neurocognitive Functioning
The chronotype, which reflects the circadian rhythm preferences of individuals in their daily activities and sleep-wake cycles, can be considered on a dimension of extreme morningism and extreme eveningism. Individuals with extreme morning and extreme evening chronotypes face many physical and psychological dangers due to accumulated sleep debt, short total sleep time and insufficient sleep efficiency. In extreme chronotypes, especially in extreme evening people, the social jet-lag effect due to the mismatch between social and circadian clocks is thought to exacerbate these dangers. More recent studies have suggested that social jet-lag and chronotype have many negative effects on cognitive functioning. The aim of this article is to review the impact of social jet-lag and chronotype on cognitive functioning
Personality Development
Personality is the integration of characteristics acquired or brought by birth which separate the individual from others. Personality involves aspects of the individual's mental, emotional, social, and physical features in continuum. Several theories were suggested to explain developmental processes of personality. Each theory concentrates on one feature of human development as the focal point, then integrates with other areas of development in general. Most theories assume that childhood, especially up to 5-6 years, has essential influence on development of personality. The interaction between genetic and environmental factors reveals a unique personality along growth and developmental process. It could be said that individual who does not have any conflict between his/her basic needs and society's, has well-developed and psychologically healthy personality
Evaluation of inflammatory status in blood in patients with rosacea
Abstract Rosacea is a chronic inflammatory skin disease that is characterized by recurrent episodes of erythema, telangiectasia and papulopustular lesions. Although the pathogenesis is not well established, growing knowledge suggests that multiple etiological factors play a role resulting in inflammation. The aim of the present study is to investigate inflammatory status of patients with rosacea by evaluating CBC parameters and systemic immune inflammation (SII) index and compare these parameters with control group. Thus, it is aimed to understand the role of systemic inflammation in the pathogenesis of the disease. This retrospective, case–control study included 100 patients with rosacea and 58 sex- and age-matched controls. Laboratory examinations including CBC, ESR, CRP, HDL, LDL, and triglyceride levels were recorded and neutrophil–lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR), monocyte-to-high-density lipoprotein ratio (MHR) and SII index were calculated. Monocyte and platelet count, SII index, ESR and CRP were significantly higher in patients with rosacea than in the control group. No statistically significant difference was found in other parameters. There was no significant correlation between disease severity and ESR, CRP, and SII index. The findings of this study suggest that apart from the inflammatory pathways at the level of skin, there is an inflammatory state in the blood of patients. Rosacea is a skin disease, but it may have systemic implications and/or associations that need to be clarified completely
Protein-based complex medium design for recombinant serine alkaline protease production
This work reports on the design of a complex medium based on simple and complex carbon sources, i.e. glucose, sucrose, molasses, and defatted-soybean, and simple and complex nitrogen sources, i.e. (NH4)(2)HPO4, casein, and defatted-soybean, for serine alkaline protease (SAP) production by recombinant Bacillus subtilis carrying pHV1431::subC gene. SAP activity was obtained as 3050 U cm(-3) with the initial defatted-soybean concentration C-soybean(o) = 20 kg m(-3) and initial glucose concentration C-G(o) = 8 kg m(-3); whereas, addition of the inorganic nitrogen source (NH4)(2)HPO4 decreased SAP production considerably. Further increase in SAP production (3850 U cm(-3)) was obtained when sucrose was replaced with glucose at C-sucrose(o) = 15 kg m(-3) and C-soybean(o) = 20 kg m(-3). Nevertheless, when molasses was replaced with sucrose, the maximum activity was obtained with molasses having 10 kg m(-3) initial sucrose concentration and C-soybean(o) = 15 kg m(-3) as soybean 2130 U cm(-3); moreover, when casein was replaced with defatted-soybean SAP production decreased considerably (ca. 250 U cm(-3)). Thereafter. the effects of inorganic ionic compounds were investigated; and except phosphate, inorganic compounds supplied from defatted-soybean were found to be sufficient for the bioprocess. The highest SAP activity was obtained as 5350 U cm(-3) in the medium that contained (kg m(-3)): C-soybean(o) = 20, C-sucrose(o) = 15, C-Na2HPO4(o) = 0.021, and C-NaH2PO4(o) = 2.82 that was 6.5-fold higher than that of the SAP produced in the defined medium. By using the designed complex medium, oxygen transfer characteristics of the bioprocess were investigated; and, Damkohler number that is the oxygen transfer limitation increases with the cultivation time until t = 14 h; and, at t > 20 h both mass transfer and biochemical reaction resistances were effective. Overall oxygen transfer coefficient varied between 0.010 and 0.044 s(-1); volumetric oxygen uptake rate varied between 0.001 and 0.006 mol m(-3) s(-1); and specific oxygen uptake rate varied between 0.0001 and 0.0022 mol kg(-1) DW s(-1) throughout the bioprocess
Nasal Congenital Panfollicular Nevus
Congenital nasal midline lesions are rarely observed pathologies. While relatively frequently encountered lesions are dermoid cyst, glioma, encephalocele, nasal polyp and epidermoid cyst, an other very rare reason is the congenital panfollicular nevus. The treatment of this syndrome appearing with a recurrent discharge in clinic is the surgical excision. We will hereby present the excision of the case of congenital panfollicular nevus with three different fistula openings
Dermatological Findings in Turkish Paediatric Haematology-Oncology Patients.
OBJECTIVE: Diagnoses of skin, mucosae, hair and nail manifestations in malignant diseases are often challenging because of life-threatening drug reactions, opportunistic infections or skin involvement of primary processes. Description of morphology, configuration and distribution of lesions is important in order to differentiate the self-healing eruptions from serious side effects of chemotherapy. There are case reports from Turkey including dermatological manifestations of malignancies and case series in adult patients but there are no published large group studies assessing all manifestations in children. The aim of this study was to evaluate the morphological features of dermatological findings in children with haemato-oncological diseases. MATERIALS AND METHODS: The study was performed at the Erciyes University, Faculty of Medicine Pediatric Hematology-Oncology Clinic, Turkey. Three dermatologists daily consulted all patients admitted to the clinic during a one-year period. RESULTS: The study group comprised of 157 children (79 female/78 male) aged 1–16 years (mean 7.19±4.63). Detailed dermatological examinations were performed, including oral-genital mucosae, hair and nails. Thorough skin examination revealed that 70% of the patients exhibited at least one dermatological finding. Generalized xerosis and hyperpigmentation were the most common findings among patients undergoing chemotherapy (24.19%). Multiple nevi on at least 10 covered areas were very frequent among patients undergoing long-term chemotherapy (18.47%). Three were identified as dysplastic nevus, but malignant transformation was not observed during the one-year study period. CONCLUSION: Regular dermatological consultation may help resolve the diagnostic and therapeutic problems in paediatric haemato-oncology clinics
