Mitochondria dynamic is regulated by different proteins, maintaining a balance between fission and fusion. An imbalance towards mitochondrial fission has been associated with tumor cell proliferation. The aim of this study was to analyze whether pectin modifies the viability of human colon cancer cells and the expression of proteins involved in mitochondrial fusion and fission. The human colon carcinoma cell line HT29 cells was growth in 10% fetal bovine serum in the absence and presence of pectin. Pectin reduced HT29 cell viability in a concentration-dependent manner, reaching a plateau at 150∼300 μ㏖/L pectin. The presence of 200 μ㏖/L pectin reduced the expression of dynamin-related protein-1 and increased expression of the mitochondrial fusion-associated proteins mitofusin-1 and 2. Expression of cyclin B1, a protein involved in G2/M transition, was found decreased in pectin-incubated HT29 cells. Moreover, expression of p53 protein, the amount of p53 in the nucleous and β-galactosidase activity, which are all biomarkers for cellular senescence, were significantly higher in pectin-incubated HT29 cells than in HT29 cells incubated without pectin. Expression of the protein B-cell lymphoma 2 (Bcl-2) homologous antagonist/killer was increased in response to incubation with pectin. However, incubation with pectin did not affect expression of Bcl-2-associated X protein or Bcl-2, or the caspase-3 activity. Overall, we concluded that pectin reduces the viability of human HT29 colon cancer cells, which is accompanied with a shift in the expression of proteins associated with mitochondrial dynamics towards mitochondrial fusion. Moreover, incubation with pectin favors cellular senescence over apoptosis in HT29 cells.

Pulmonary Embolism from Cement Augmentation of the Vertebral Body
Jose Manuel Fernando Ignacio,Katrina Hannah Dizon Ignacio 대한척추외과학회 2018 Asian Spine Journal Vol.12 No.2
Pulmonary cement embolism (PCE) can follow cement augmentation procedures for spine fractures due to osteoporosis, traumatic injuries, and painful metastatic lesions. PCE is underreported and it is likely that many cases remain undiagnosed. Risk factors for PCE have been identified, which can help alert clinicians to patients likely to develop the condition, and there are recommended techniques to reduce its incidence. Most patients with PCE are asymptomatic or only develop transient symptoms, although a few may exhibit florid cardiorespiratory manifestations which can ultimately be fatal. Diagnosis is mainly by radiographic means, commonly using simple radiographs and computed tomography scans of the chest with ancillary tests that assess the patient’s cardiorespiratory condition. Management depends on the location and size of the emboli as well as the patient’s symptomatology. The aim of this review is to raise awareness of the not uncommon complications of PCE following vertebral cement augmentation and the possibility of serious sequelae. Recommendations for the diagnosis and management of PCE are presented, based on the most recent literature.

While the retrial phenomenon plays an important role in communication networks and should not be ignored, retrial systems do not present an exact analytic solution, so approximate techniques are required. To the best of our knowledge, all the existing techniques are based on computing the steady states probabilities. We propose another approach based on the relative state values which appear in the Howard equations. The results of the numerical evaluation carried out show that this solution outperforms previous approaches in terms of both accuracy and computation time.

One specimen of Pteraclis aesticola was collected off San Jose del Cabo, Baja California Sur, Mexico ($22^{\circ}54'N$, $109^{\circ}45'W$), in March 2007. Present record is the first reported occurrence of the species in the Tropical Eastern Pacific biogeographic region (Gulf of California to southern Ecuadorian waters). Its large fan-like anal and dorsal fins and its counts of fin rays and vertebrae can distinguish the Pacific fanfish from the other species in the genus. This fish may have not yet been recorded in the region because its presence has been overlooked in the past because of rarity and lack of commercial value.

This study is derived from qualitative research during the period 2007-2009 in an urban marginalized sector at the periphery of the Guadalajara Metropolitan Area (GMA). The poverty conditions for women and their households make the work one of the main resources to confront and cover the most basic needs. The impact of global processes of crisis and economic restructuration, as well as labor flexibility trends over the operation of labor markets (Garcia y Oliveira 1994, 1998; Oliveira y Ariza 1998, 2000, 2001) have been highlighted in its precariousness, situations that have affected the conditions of work for women. From a multidimensional perspective, it is analyzed the diverse types and forms of precarious work for women, as well as the social vulnerability in which they inhabit; this framework proposed by Caroline(1996) allows to visualize the three levels in which it increases or decreases when the units of analysis are based on the individual, the household and the community. The leads to a holistic comprehension of the scenarios in which vulnerability acquires relevant overtones in order to deepen on the different dynamics and processes in which feminine work is immerse. In this sense, with an approximation of the social actors situated in this precarious stage, it is considered from the standpoint of Rocio(2003, 150), that “the study of subjectivity cannot be ignored when seeking to understand changing and dynamic processes of the phenomena of social vulnerability and the roll that plays the access of work in the struggle for survival”. Hence that the deep interviews with a biographical approach realized to women of urban sector contribute to the construction of the meanings the practices around feminine work.

Myofibrillar protein are the principally responsibleof gelling properties in fishery resource, hence, during proteinconcentrate or isolated proteins preparation, sarcoplasmicprotein are discarded; however, myofibrillar protein cansupport low levels of sarcoplasmic proteins without affectingthe gelling property. Therefore, the aim of this study was togradually remove sarcoplasmic proteins from giant squidmantle by means of different ionic strengths (I). Solutionsof NaCl with different ionic strengths (I=0.0, 0.1, and 0.3)were used to obtain 3 protein concentrates. The electrophoreticprofile in SDS-PAGE showed differences in protein removalwith a high solubility of mantle proteins. The texture profileanalysis showed that hardness increased in mantle proteinwashed with higher I. The total reactive sulfhydryls showedsignificant changes (p<0.05) detecting major formation ofS-S bonds with protein removal at an I of 0.3. Differentialscanning calorimetry showed a minor denaturation temperatureof the actomyosin complex when protein removal wasperformed with an I of 0.3. The present study indicates thatremoval of sarcoplasmic protein as a function of I results inbetter quality gels.

Efforts aimed at reduction of fishing waste generated during the evisceration and filleting are scarce. The fishing waste is used in the production of low value-added products, such as flours or silages. It is important to visualize an alternative and profitable use of this waste, as it constitutes a serious environmental problem. This research determined the antioxidant properties of collagenous extracts of skin and galls of Oreochromis sp. The raw materials were characterized by proximal chemical analysis. Three treatments were applied to extract the collagen: salt-soluble collagen, acid-soluble collagen (ASC), and pepsin-hydrolyzed collagen (PHC). The collagenous fractions were hydrolyzed (0.1% pepsin). The recovered collagen yield and antioxidant activity were determined to hydrolyzed collagen (HC) and nonhydrolyzed collagen (NHC). The ASC skin showed the highest extraction yield (3.02%). For galls, only the PHC extraction was feasible (0.16%). Antioxidant analysis of NHC did not reveal radical scavenging activities. HC displayed a 2,2-diphenyl-1-picrylhydrazyl %RSA of 22.58 (ASC skin) and 10.34% (PHC galls), and a 2,2′-azino-bis[3-ethylbenzothiazoline-6-sulfonic acid] %RSA of 30.40% (PHC skin) and 29.43% (PHC galls), respectively. The ASC skin and PHC gall extracts exhibited 94.40% and 81.54% in ferric-reducing antioxidant power, and 43.63 and 38.08 μg ascorbic acid equivalents per milli liter for total antioxidant capacity, respectively. The collagen extracts showed %RSA and chelation of pro-oxidant metal ions. Different mechanism of antioxidant action was identified for the extracts: radical scavengers for HC and metal ion chelators for NHC. In conclusion, red tilapia skin collagen is recommended as an active ingredient of nutraceuticals, pharmaceuticals, or functional foods, for the identified bioactive properties.
