Abstract

Background: Circadian preference refers to individual differences for mental and physical activity in the morning and evening. We hypothesized, that inadvertent use of electronic media can cause circadian misalignment that influences sleeping habits and sleep quality of young adults. Aims and Objectives: The aim of the study was to investigate the effect of circadian preferences on sleeping habits and the association of electronic media use with sleep quality and sleep disturbances. Materials and Methods: A total of 188 subjects were enrolled and divided into three groups: Evening, intermediate, and morning chronotype based on the Morningness-Eveningness score. Electronic media use at bedtime and duration of use were assessed subjectively. Sleep quality and subjective sleep disturbances, daytime sleepiness, and chronotype were assessed by the Pittsburgh Sleep Quality Index, Epworth Sleepiness Score, and Morningness-Eveningness Questionnaire Self-assessment version, respectively. Results: The majority of subjects with the evening chronotypes suffered from poor sleep quality compared to other chronotypes and the difference was statistically significant. In evening-type subjects, electronic media use at bedtime, long sleep latency, short sleep duration, and daytime sleepiness were significantly associated with poor sleep quality with odds ratios of 2.34 (1.08-5.08), 11.42 (4.98-26.19), 8.54 (1.01-68.24), and 1.68 (1.03-2.73), respectively. Conclusion: The majority of evening-type subjects had poor sleep quality, altered sleeping habits, and electronic media use at bedtime is significantly associated with poor sleep quality. Hence, history regarding sleep habits and lifestyle, especially electronic media use, should be taken from young adults, who are coming to the outpatient department for other than sleep disorders, to prevent the development of health-related problems.

Abstract

The application of scaffolding materials is believed to hold enormous potential for tissue regeneration. Biological scaffolds can also be decellularised using herbal agents which have emerged as promising protocol for replacing defective tissues. Residual cytotoxicity is one of the major disadvantages of non-herbal biological detergents. The aim of this study is to modify the protocol for decellularization and its evaluation using hematoxylin-eosin staining, diamidino-2-phenylindol (DAPI) staining and DNA quantification. In this research work, we decellularized caprine urinary bladder tissues by the using Sapindus mukorossi fruit pericarp extract (SPE) by completely removing the urinary bladder cellular components with no cytotoxicity. Efficiency of decellularization and preserved three dimensional structure of scaffold were confirmed by histological analysis (hematoxylin and eosin stained tissue samples). Non-immunogenicity of scaffold was confirmed complete removal of nuclear components and DNA content measurement which was verified by DAPI stained micrograph. It was concluded that Sapindus mukorossie 10% aqueous extract (SPE) is an ideal for preparation of decellularized caprine urinary bladder scaffold. [ABSTRACT FROM AUTHOR]

Abstract

Purpose: The commonly used decellularization agent such as sodium dodecyl sulfate, Triton X-100, and sodium deoxycholate has the potential to cause residual cytotoxic effects in the extracellular matrix. The present study was conducted to establish a protocol for decellularization of caprine gall bladder using aqueous soap nut (Sapindus mukorossi) pericarp extract. Methods: The gall bladder tissues were decellularized using 5% aqueous extract of Sapindus mukorossifruit pericarp under continuous agitation on the magnetic stirrer and crosslinked with glutaraldehyde. The efficacy of the decellularization process was verified with the help of histology, scanning electron microscopy, DAPI staining, and DNA content estimation. The physico-chemical properties of crosslinked scaffolds were evaluated by enzymatic and non-enzymatic degradation, free protein, free amino group, fixation index, hydroxyproline, and moisture content. Results: The gall bladder tissue was completely decellularized at 72-h interval. The weight loss of decellularized glutaraldehyde crosslinked scaffolds following non-enzymatic, and collagenase digestion significantly increased with the digestion time interval. The free protein and free amino acid group concentration of acellular gall bladder matrix was significantly (P< 0.05) higher than crosslinked tissues collected at different crosslinking time intervals. The fixation index was highest in tissues crosslinked for 72 h. The moisture content at the 72 h crosslinking interval was significantly lower (P< 0.05). The free hydroxyproline content in the crosslinked acellular matrices was nil and did not show any band pattern in SDS-PAGE gel. Conclusion: The findings from this study indicate that soap nut pericarp extract is a viable option for decellularizing caprine gall bladder without any toxicity. Lay Summary and Future Work: The commonly used decellularization agent such as sodium dodecyl sulfate, Triton X-100, and sodium deoxycholate has the potential to cause residual cytotoxic effects in the extracellular matrix. So, we used aqueous soap nut (Sapindus mukorossi) pericarp extract for decellularization of caprine gall bladder. The efficacy of the decellularization process was verified with the help of histology, scanning electron microscopy, DAPI staining, and DNA content estimation. The physico-chemical properties were evaluated by enzymatic and non-enzymatic degradation, free protein, free amino group, fixation index, hydroxyproline, and moisture content. The gall bladder tissue was completely decellularized at 72-h interval. The findings from this study indicate that Sapindus mukorossifruit pericarp extract is a viable option for decellularizing caprine gall bladder without any toxicity.

Abstract

In the present study fibroblasts seeded matrices prepared from bovine pericardium was evaluated in the repair of full thickness skin defects in rats. The pericardium tissue from buffalo was treated with 1% sodium dodecyl sulphate (SDS) for 48 hours showed complete acellularity with normal thickness and arrangements of collagen fibres. In vitro primary mouse embryonic fibroblasts (p-MEF) cells were cultured and seeded on the acellular pericardium matrix (APM) using static seeding technique. Forty eight (48) rats of either sex were randomly divided into 4 groups of 12 animals each. Under general anaesthesia a 20x20 mm2 full thickness skin defect was created on dorsal thoracic area. The defect in group A (control) was repaired with standard dressing material whereas, groups B, C and D animals were repaired with autograft, APM and p-MEF seeded APM, respectively. Wound healing was evaluated on the basis of clinical, gross, immunological and histopathological observations. On the basis of different observations recorded it can be said that APM have wound healing potency however, seeding with p-MEF increases the wound healing potency. APM seeded p-MEF was found to be a novel biomaterial which has amphipathic character in full thickness skin repair and enhances wound healing. [ABSTRACT FROM AUTHOR]

Abstract

Animal tissues are extensively used as scaffolds for tissue engineering and regenerative therapies. They are typically subjected to decellularization process to obtain a cell-free extracellular matrix (ECM) scaffolds. It is important to identify chemical structure of the ECM scaffolds and Fourier transform infrared (FTIR) appears to be a technique of choice. In this chapter, FTIR spectra of native and decellularized buffalo aortae, buffalo diaphragms, goat skin, and native bovine cortical bone are presented. The transmittance peaks are that of organic collagen amide A, amide B, amide I, amide II and amide III chemical functional groups in both native and decellularized aortae, diaphragms and skin. In bone, the transmittance peaks are that of inorganic ν1, ν3 PO43−, OH− in addition to organic collagen amide A, amide B, amide I, amide II and amide III chemical functional groups. These important transmittance peaks of the tissue samples will help researchers in defining the chemical structure of these animal tissues.

Abstract

Background: Studies have shown that alterations in the sleep cycle can predispose to several disorders. Most of the previous studies were done on the adults. Hence, the aim of the study was to see the effect of circadian disruption on the health of adolescent population., Materials and Methods: In this cross-sectional study, 203 subjects were enrolled. Study subjects were divided into three groups: definite evening chronotype, intermediate chronotype, and definite morning chronotype. Sleep quality was measured by Pittsburgh Sleep Quality Index (PSQI). Daytime sleepiness and chronotype were measured by Epworth Sleepiness Score and Morningness-Eveningness Questionnaire Self-Assessment version, respectively. Two hours postprandial glucose was measured after oral glucose tolerance test. Fasting blood glucose and fasting insulin were measured. Homeostasis model of assessment for insulin resistance (HOMA-IR) was calculated. Data were summarized as mean ± standard deviation. Crude odds ratios and Karl Pearson's correlation coefficient of metabolic parameters with poor sleep were calculated., Results: Statistically significant difference was found in the mean value of poor sleep quality, 2 h postprandial blood glucose level, and insulin resistance among subjects of three groups. Subjects of evening chronotype have more significant positive correlation of 2 h postprandial blood glucose level and HOMA-IR value with poor sleep quality when compared with subjects of intermediate and morning chronotypes., Conclusion: Subjects with evening chronotype are more prone for development of metabolic syndrome compared with subjects of intermediate and morning chronotypes if proper health policies are not adopted for adolescents., Competing Interests: There are no conflicts of interest.

Abstract

Alzheimer's disease is the most common form of age related cognitive impairment. Aim of the present study was to see the effect of vitamin D on cognitive function in elderly. The study was conducted in Department of Physiology, King George's Medical University (KGMU). A total of 80 subjects were enrolled based on Mini Mental State Examination (MMSE) score < 24 and vitamin D deficiency. They were divided into two groups as Group A (case) and Group B (control), each group having 40 subjects. Intervention (Vitamin D supplementation) was given in Group A. The assessment of dementia was done by Mini Mental State Examination (MMSE) score. Every subject was clinically evaluated and estimation of vitamin D was done by direct ELISA kit. Gender, weight, height, BMI, residence and education were also similar between two groups. A significant (p=0.0001) change in MMSE score was observed in both Group A and Group B from baseline to 3 & 6 months and from 3 to 6 months, however, mean change was higher in Group A than Group B. In conclusion, vitamin D supplementation caused significant improvement in the cognitive performance in subjects with senile dementia.
