Objective: This study aimed to evaluate the replacement of degummed soybean oil (DSO) by acid soybean oil (ASO) in diets with or without the inclusion of emulsifier on broiler performance, relative organ weight, lipase activity, intestinal morphometry, and nutrient digestibility. Methods: A total of 704 1-day-old male broiler chicks were allotted to a 2×2 completely randomized factorial design (with or without emulsifier × two lipid sources [ASO and DSO]), with eight replicates and 22 birds each. The metabolizable energy level in diets with emulsifier was reduced by 40 kcal/kg from 1 to 21 d and 50 kcal/kg from 22 to 49 d. Results: Broilers fed diets containing ASO without emulsifier had higher (p = 0.005) weight gain than DSO-fed animals and with the inclusion of emulsifier had worse (p = 0.018) feed conversion ratio (FCR). Birds fed diets with emulsifier worsened FCR regardless of lipid source from 1 to 21 days (p = 0.006) and from 1 to 49 days (p = 0.0002). There was an increase (p = 0.026) in the relative pancreas weight, at 14 days, in birds fed diets containing ASO. Lipase activity and morphometry of the duodenum and jejunum, at 14 and 21 days, were not affected (p>0.05). The dietary inclusion of emulsifier improved the digestible energy (p = 0.053) in the presence of ASO. For the digestibility coefficients (gross energy, crude protein, and mineral matter), no interference was observed (p>0.05). Conclusion: The inclusion of emulsifier to energy-restricted diet with ASO maintained broiler performance in the first week, but worsened FCR in subsequent phases. The ASO can be considered as an alternative lipid source to DSO and does not interfere with the morphophysiological characteristics and performance of broilers. The combination of ASO and emulsifier increased the digestible energy content by 6.2%.

Z-R relationships were developed for the Eastern Coast of Northeastern Brazil (NEB) using rainfall raindrop size distribution (RSD)data collected with a disdrometer RD-69 in the Campus of the Universidade Federal de Alagoas (UFAL: The Federal University of Alagoas) in Maceió in 2001. The RSD was stratified by rainfall rate classes. It is found that the RSD are clearly dependent on the parameters of the analytical distribution functions are, and show a marked monthly variability. The parameters of the frequency distributions are dependent on the rain rate (R). The forms of RSDs are similar to previous studies but the amount of droplets is not in each one very strongly. This may be possible due to the short period of data collection or to the intraseasonal rainfall variability. The general relationship for the Eastern Coast of NEB was found to be Z = 176.5 R1.29, with correlation coefficient equal to 0.83. This equation is in accordance with the ones for stratiform rain reported in the literature. We found that the convective rain observed is produced by convective cells imbedded into stratiform cloud layers. However, when separating stratiform and convective rainfall we found that the linear coefficient of the Z-R relation is significantly smaller for convective rainfall than for stratiform one (65 and 167 respectively), but the exponential coefficient is higher for convective than for stratiform (1.69 and 1.26 respectively).

Osteoma is a benign osteogenic tumor composed of cancellous or compact bone, classified as peripheral, central, or extraskeletal. Peripheral osteomas are uncommon. Excluding the maxillary sinuses, the maxilla is a rare site for osteomas. The purpose of this report was to describe clinicopathological and radiological features of two peripheral osteomas occurring in the jaws, one located in the mandible and another in the edentulous maxillary alveolar ridge. The tumors were asymptomatic and were fully excised without any complications or recurrence. The lesions were submitted to histopathological analysis and diagnosed as peripheral osteoma, compact type.

Autophagic elimination of Trypanosoma cruzi in the presence of metals

Laís Pessanha de Carvalho,Edésio José Tenório de Melo 한국미생물학회 2019 The journal of microbiology Vol.57 No.10

Trypanosoma cruzi is an obligate intracellular parasite transmitted to vertebrate hosts by blood-sucking insects. Molecules present in parasites and mammalian cells allow the recognition and parasite internalization. Metallic ions play an essential role in the establishment and maintenance of hostparasite interaction. However, little is known about how parasites handle with essential and nonessential metal quotas. This study aimed to investigate the influence of metal ions on the biological processes of T. cruzi infected cells. Infected cells were incubated with ZnCl2, CdCl2, and HgCl2 for 12 h and labeled with different specific dyes to investigate the cellular events related to intracellular parasite death and elimination. Infected host cells and parasite’s mitochondria underwent functional and structural disorders, in addition to parasite’s DNA condensation and pH decrease on host cells, which led to parasite death. Further investigations suggested that lysosomes were involved in pH decrease and the double membrane of the endoplasmic reticulum formed vacuoles surrounding damaged parasites, which indicate the occurrence of autophagy for parasite elimination. In conclusion, low concentrations of nonessential and essential metals cause a series of damage to Trypanosoma cruzi organelles, leading to its loss of viability, death, and elimination, with no removal of the host cells.

이 연구는 브라질 북동부의 Maceió-Alagoas 지역에서 강우로 인한 토양의 침식 지수를 추정할 수 있는 알고리즘을 결정하는 것을 목적으로 한다. 2003년부터 2006년까지 10분 이상 지속된 680회의 강우 사례에서 수집한 분당 26,889개의 데이터 샘플은 우적 크기 분포에 따라 분류되었다. 종속 변수와 독립 변수로 구성된 방정식은 99%의 결정 계수로 침식지수를 추정한다. 최소 강우 강도와 침식도의 관계는 통계적 유의성으로 검증되었다. This study is aimed at determining an algorithm capable of estimating the erosion index of rainfall for the region of Maceió-Alagoas in the northeast of Brazil. The sample of the truncated data from 2003 to 2006 counts 26,889 droplet size distributions integrated per minute, with 680 rain events with duration longer than 10 minutes. The equation proposed to estimate erosion index used as a dependent variable and independent variable, presenting a coefficient of determination of 99%. The statistical significance validated the relation between minimum rainfall intensity and erosion.

강우는 토양 침식을 일으키는 가장 능동적인 힘 중 하나이다. 다양한 속도와 운동에너지를 가지고 낙하하는 우적은 토양에 충격을 주는 침식력으로 작용한다. 우적의 변동 속도와 운동에너지는 우적의 직경에 직접적으로 의존한다. 이 연구의 목적은 브라질 Alagoas주 Maceió 지역에서 강우에 의한 토양 침식을 산정 할 수 있는 알고리즘을 결정하는 것이다. 이를 위해 1분 간격의 강우 분포를 지속적으로 자동 측정하는 RD-69 디즈드로미터를 사용하여 2003년부터 2006년까지 침식성 강우 자료를 수집하였다. 독립 변수가 강수량인 지수 관계식과 독립 변수가 지속 시간과 최대 강도인 지수 관계식 형태로 최적화된 알고리즘이 결정되었다. Rainfall is one of the most active forces that cause soil erosion. The action of rain on the soil exerts an erosive power caused by the impact of the drops, which fall with variable speed and kinetic energy, depending directly on the diameter of the drop. The objective of this study is to determine algorithms capable of estimating rainfall erosivity for the region of Maceió-AL. For this purpose, erosion rains were collected between 2003 and 2006 using a RD-69 disdrometer, which continuously and automatically measures rainfall distribution in a range of 1 min. The determination of algorithms in the form of power equation to estimate was adjusted with one and two independent variables (amount of rainfall, duration and maximum intensity).

지표면 침식 잠재력은 비가 내린 영향으로 토양에 전달 된 운동 에너지로 평가할 수 있다. 대륙 강수의 97%와 해양 강수의 95%가 강우량과 강우율의 관계로 이루어진 지수 방정식으로 설명되었다. 이 방정식의 지수는 강우 유형에 의존하지 않는다. 그러나 계수는 강우 사건에 따라 조정될 수 있는 변동을 나타냈다. 이 방정식은 결정 계수, 평균 절대 오차 및 신뢰 오차에 의해 검증되었다. 특정 유형의 토양과 관련된 강수의 운동 에너지는 강우로 인한 침식의 가능성을 결정할 수 있다. The erosive potential of precipitation can be evaluated by the kinetic energy transferred to the soil by the impact of the rain drop. A kinetic energy rate of the rain drops was estimated by the disdrometer classifying impact signals. This equation in the form of power presented an adjustment measure between the rain rate and rainfall quantity of 97% and 95% for continental and maritime rains, respectively. The exponent of the power equation, initially, shows no dependence on the type of rainfall. However, the multiplicative factor presented variation, which can be adjusted according to rainfall events. This equation was validated by the coefficient of determination, the average absolute error and the confidence error. The kinetic energy of precipitation, associated to certain types of soil, will allow the determination of the potential of the erosion caused by the rains.

Brazil Alagoas 주의 동부 지역에서 우적 크기를 측정하는 디즈드로미터(disdrometer)로 산출한 강우량과 강우율의 관계로 우적의 역학 에너지가 예측되었다. 강우의 시작과 끝에서 측정되는 약한 강우 강도에서는 지수 형태의 방정식이 큰 우적의 영향을 억제하였다. 빗방울의 역학 에너지는 거의 모든 강우 강도 범위에서 과소평가 되었다. 결정 계수, 평균 절대 오차, 상대 오차 비율, 평균 절대 오차, 평균 제곱 오차, Willmott의 일치지수 및 신뢰 지수와 같은 성과 지표에 기반을 두어 예측된 강우 역학 에너지가 유용한 결과로 평가되었다. The kinetic energy of the rain drops was predicted in a relation between the rain rate and rain quantity, derived directly from the rain drop size distribution (DSD), which had been measured by a disdrometer located in the eastern state of Alagoas-Brazil. The equation in the form of exponential form suppressed the effects of large drops at low rainfall intensity observed at the beginning and end of the rainfall. The kinetic energy of the raindrop was underestimated in almost rain intensity ranges and was considered acceptable by the performance indicators such as coefficient of determination, average absolute error, percent relative error, mean absolute error, root mean square error, Willmott s concordance index and confidence index.
