Cinnamon has a history of use for medicinal purposes and its major benefits have been linked to cinnamaldehyde. The present study aimed to investigate the hypoglycemic action of cinnamaldehyde against fatty-sucrosed diet/streptozotocin (FSD/STZ)-rat model of gestational diabetes. Female albino rats were divided into three groups. Group I fed with normal diet (ND) while group II and III were fed with FSD for eight weeks (five weeks pre-gestational and three weeks gestational). Rats of group III were administered with a daily oral dose of 20mg/kg cinnamaldehyde one week before mating onward...

The cardiotoxicity of arsenic trioxide (ATO) limits its clinical application in cancer treatment. Evidences suggest that sorbus has antioxidant activity and its consumption has been linked with improved cardioprotection. In this study, we investigated the cardio-protective effect and mechanisms of Sorbus pohuashanensis (Hante) Hedl. flavonoids (SPF) against ATO in BALB/c mice and H9c2 cells. Eleven major flavonoids were confirmed by ultra-performance liquid chromatography electrospray ionization quadrupole time of flight mass spectrometry (UPLC-ESI-Q-TOF-MS)...

The periosteum plays a critical role in bone homeostasis and regeneration. It contains a vascular component that provides vital blood supply to the cortical bone and an osteogenic niche that acts as a source of bone-forming cells. Periosteal grafts have shown promise in the regeneration of critical size defects, however their limited availability restricts their widespread clinical application. Only a small number of tissue-engineered periosteum constructs (TEPCs) have been reported in the literature. A current challenge in the development of appropriate TEPCs is a lack of pre-clinical models in which they can reliably be evaluated...

In this study, the industrial textile wastewater was treated using a chemical-based technique (coagulation-flocculation, C-F) sequential with an advanced oxidation process (AOP: Fenton or Photo-Fenton). During the C-F, Al2(SO4)3 was used as coagulant and its optimal dose was determined using the jar test. The following operational conditions of C-F, maximizing the organic matter removal, were determined: 700 mg/L of Al2(SO4)3 at pH = 9.96. Thus, the C-F allowed to remove 98% of turbidity, 48% of Chemical Oxygen Demand (COD), and let to increase in the BOD5/COD ratio from 0...

In this paper I propose to reflect upon modern configuration of technique, i.e., technoscience, and our responsibility towards environmental management. I show that the technological products of our world imply a certain attitude of aggression towards nature, contrasting with the attitude of protection from her, which was peculiar of the pre-technological world. Finally I suggest recovering the classical notion of politics as a possible alternative for controlling techno-scientific imperatives.

Deadenylases are best known for degrading the poly(A) tail during mRNA decay. The deadenylase family has expanded throughout evolution and, in mammals, consists of 12 Mg(2+)-dependent 3'-end RNases with substrate specificity that is mostly unknown. Pontocerebellar hypoplasia type 7 (PCH7) is a unique recessive syndrome characterized by neurodegeneration and ambiguous genitalia. We studied 12 human families with PCH7, uncovering biallelic, loss-of-function mutations in TOE1, which encodes an unconventional deadenylase...

Multidrug-resistant tuberculosis (MDR-TB), caused by drug-resistant strains of Mycobacterium tuberculosis, is an increasingly serious problem worldwide. Here we examined a data set of whole-genome sequences from 5,310 M. tuberculosis isolates from five continents. Despite the great diversity of these isolates with respect to geographical point of isolation, genetic background and drug resistance, the patterns for the emergence of drug resistance were conserved globally. We have identified harbinger mutations that often precede multidrug resistance...

The tumour suppressor p53 is a transcription factor that controls cellular stress responses. Here, we dissected the transcriptional programmes triggered upon restoration of p53 in Myc-driven lymphomas, based on the integrated analysis of p53 genomic occupancy and gene regulation. p53 binding sites were identified at promoters and enhancers, both characterized by the pre-existence of active chromatin marks. Only a small fraction of these sites showed the 20 base-pair p53 consensus motif, suggesting that p53 recruitment to genomic DNA was primarily mediated through protein-protein interactions in a chromatin context...

Many high-throughput experimental technologies have been developed to assess the effects of large numbers of mutations (variation) on phenotypes. However, designing functional assays for these methods is challenging, and systematic testing of all combinations is impossible, so robust methods to predict the effects of genetic variation are needed. Most prediction methods exploit evolutionary sequence conservation but do not consider the interdependencies of residues or bases. We present EVmutation, an unsupervised statistical method for predicting the effects of mutations that explicitly captures residue dependencies between positions...

The cytoplasmic polyadenylation element-binding (CPEB) proteins regulate pre-mRNA processing and translation of CPE-containing mRNAs in early embryonic development and synaptic activity. However, specific functions in adult organisms are poorly understood. Here we show that CPEB4 is required for adaptation to high-fat-diet- and ageing-induced endoplasmic reticulum (ER) stress, and subsequent hepatosteatosis. Stress-activated liver CPEB4 expression is dual-mode regulated. First, Cpeb4 mRNA transcription is controlled by the circadian clock, and then its translation is regulated by the unfolded protein response (UPR) through upstream open reading frames within the 5'UTR...

Electroencephalography (EEG) has been reported as an objective, non-invasive and stress free technique for nociceptive studies. Electrical stimuli can be used to evaluate the efficacy of centrally acting agents. Peripheral nerve stimulator can be a good and cheap source of electric stimulus for studies of nociception, and studies evaluating analgesic effect of drugs under EEG. In this study suitability of peripheral nerve stimulator, and milliamperage for nociceptive studies under electroencephalography were evaluated...

Modern commercial pig farming systems inflict increased stress in animals, which often leads to various negative changes in the gastro-intestinal tract, especially in the case of piglets. Ban of antibiotics, used as growth promoters, has caused a need for alternatives to conventional antimicrobials in swine diets. Use of pre-/or probiotics, organic acids and plant extracts is often recommended, but it seems that zinc oxide and cooper salts, which were traditionally included in high doses to piglets diet, possess the highest efficacy...

Objective quality assessment of stereoscopic 3D video is challenging but highly desirable, especially in the application of stereoscopic video compression and transmission, where useful quality models are missing that can guide the critical decision making steps in the selection of mixed-resolution coding, asymmetric quantization, and pre- and post-processing schemes. Here we first carry out subjective quality assessment experiments on two databases that contain various asymmetrically compressed stereoscopic 3D videos obtained from mixed-resolution coding, asymmetric transform-domain quantization coding, their combinations, and multiple choices of postprocessing techniques...

Deriving from the gradient vector of a generative model of local features, Fisher vector coding (FVC) has been identified as an effective coding method for image classification. Most, if not all, FVC implementations employ the Gaussian mixture model (GMM) as the generative model for local features. However, the representative power of a GMM can be limited because it essentially assumes that local features can be characterized by a fixed number of feature prototypes, and the number of prototypes is usually small in FVC...

BACKGROUND: Enhanced recovery pathways (ERPs) have been shown to aid in patient recovery and improve outcomes in many surgical settings. At present, there is limited data available regarding the use and feasibility of ERPs for patients undergoing microsurgical breast reconstruction. We sought to assess patient outcomes before and after the introduction of an ERP that was adopted by multiple surgeons at a single cancer center. METHODS: A multidisciplinary ERP was developed for patients undergoing deep inferior epigastric perforator (DIEP) or muscle-sparing free transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction...

Pre-participation screening is vital to exclude inherited cardiac conditions which have the potential to cause sudden cardiac death in seemingly healthy athletes. Recent research has questioned traditional theories of load-induced, dichotomous cardiac adaptation. We therefore considered whether a "one-size-fits-all" approach to screening can account for inter-individual differences brought about by sporting discipline, training volume, ethnicity, body size, sex and age.
