Orozco, Daniela,Alarcon-Rojo, Alma Delia,Chavez-Mendoza, Celia,Luna, Lorena,Carrillo-Lopez, Luis Manuel,Ronquillo, Oswaldo Asian Australasian Association of Animal Productio 2021 Animal Bioscience Vol.34 No.10

Objective: A study was conducted to determine the physicochemical quality and consumer acceptability of beef frankfurter-type sausages formulated with pecan nut paste and Mexican oregano oil (MO) of two varieties, Poliomintha longiflora Gray (Mexican oregano Poliomintha, MOP) or Lippia berlandieri (Mexican oregano Lippia, MOL). Methods: Frankfurters were processed under six treatment conditions: control (10.67% pork fat), MOP (control + 0.01% MOP), MOL (control + 0.01% MOL), MOP-N (control + 0.01% MOP + 6% pecan nut paste), MOL-N (control + 0.01% MOL + 6% pecan nut paste), and C-N (control + 6% pecan nut paste). The physicochemical properties and the consumer acceptability were determined. Results: The addition of MO and nut did not influence the water holding capacity, drip loss, and luminosity of frankfurters, but those ingredients increased pH and shear force (p<0.05) and decreased redness (p<0.05) of frankfurters. Frankfurters were generally well accepted by consumers. However, general acceptability of sausages decreased with the addition of MO. Control sausages showed the highest acceptability. Conclusion: The MO and pecan nut paste do not affect drastically the quality of frankfurters. These results provide evidence that partial replacement of pork fat by pecan nut in frankfurters maintain a consistent physicochemical quality and its commercialization looks promising given consumers' acceptance.

Raffoul-Orozco, Abdel Kerim,Avila-Gonzalez, Ana Elisa,Barajas-Vega, Jessica Lucia,Rodriguez-Razon, Christian Martin,Garcia-Cobian, Teresa Arcelia,Ramirez-Lizardo, Ernesto Javier,Rubio Arellano, Edy Da KOREAN PHARMACOPUNCTURE INSTITUTE 2017 Journal of pharmacopuncture Vol.20 No.3

Objectives: The aim of this study was to investigate the effects of Cassia acutifolia on the obesity and the glucose levels in a rat model of obesity and diabetes. Methods: By random selection, 36 Wistar male rats were divided in two control groups, the positive and the negative control groups, and into four experimental groups receiving different infusions of Cassia acutifolia in water ad libitum. Results: The results revealed a statistically significant anti-obesogenic effect (P = 0.02), although this was not considered clinically significant. Additionally, Cassia acutifolia lowered the glucose levels by 30 mg/dL to 90 mg/dL (P = 0.05). However, we observed adverse effects in the liver, a two-fold increase in transaminase levels (P = 0.002), and in the kidneys, decreased creatinine levels (P = 0.001), and these adverse effects had no viable explanation. Conclusion: Cassia acutifolia has anti-hyperglycemic effects in obese diabetic rats. However, Cassia acutifolia also has adverse effects, so it should not be administered to patients.

Parametric survival model based on the Lévy distribution

Valencia-Orozco, Andrea,Tovar-Cuevas, Jose R. The Korean Statistical Society 2019 Communications for statistical applications and me Vol.26 No.5

It is possible that data are not always fitted with sufficient precision by the existing distributions; therefore this article presents a methodology that enables the use of families of asymmetric distributions as alternative probabilistic models for survival analysis, with censorship on the right, different from those usually studied (the Exponential, Gamma, Weibull, and Lognormal distributions). We use a more flexible parametric model in terms of density behavior, assuming that data can be fit by a distribution of stable distribution families considered unconventional in the analyses of survival data that are appropriate when extreme values occur, with small probabilities that should not be ignored. In the methodology, the determination of the analytical expression of the risk function h(t) of the $L{\acute{e}}vy$ distribution is included, as it is not usually reported in the literature. A simulation was conducted to evaluate the performance of the candidate distribution when modeling survival times, including the estimation of parameters via the maximum likelihood method, survival function ${\hat{S}}$(t) and Kaplan-Meier estimator. The obtained estimates did not exhibit significant changes for different sample sizes and censorship fractions in the sample. To illustrate the usefulness of the proposed methodology, an application with real data, regarding the survival times of patients with colon cancer, was considered.

SGLT2 Inhibitors and Ketone Metabolism in Heart Failure

Saucedo-Orozco Huitzilihuitl,Voorrips Suzanne N.,Yurista Salva R.,de Boer Rudolf A.,Westenbrink B. Daan 한국지질동맥경화학회 2022 지질·동맥경화학회지 Vol.11 No.1

Sodium-glucose cotransporter-2 (SGLT2) inhibitors have emerged as powerful drugs that can be used to treat heart failure (HF) patients, both with preserved and reduced ejection fraction and in the presence or absence of type 2 diabetes. While the mechanisms underlying the salutary effects of SGLT2 inhibitors have not been fully elucidated, there is clear evidence for a beneficial metabolic effect of these drugs. In this review, we discuss the effects of SGLT2 inhibitors on cardiac energy provision secondary to ketone bodies, pathological ventricular remodeling, and inflammation in patients with HF. While the specific contribution of ketone bodies to the pleiotropic cardiovascular benefits of SGLT2 inhibitors requires further clarification, ketone bodies themselves may also be used as a therapy for HF.

A guide to reducing adverse outcomes in rabbit models of sciatic nerve injury

Elisabeth Orozco,Koichi Masuda,Sameer B. Shah 한국실험동물학회 2021 Laboratory Animal Research Vol.37 No.2

Background Peripheral nerve damage can have debilitating consequences. Rabbit sciatic nerve transection models allow the effective evaluation of surgical repair strategies for large nerve gaps. Despite advantages in size, ease of handling, and functional utility, rabbits can suffer from a number of side effects that affect animal welfare and the quality of scientific inquiry. Such side-effects, which include pressure ulcers and traumatic damage to the foot, are primarily a consequence of insensitivity of the distal hindlimb following sciatic nerve injury. In this study, we present a number of methodologies for identifying, treating, and preventing unintended adverse effects in rabbit sciatic nerve injury models. Results First, we categorize pressure ulcers according to their severity and describe the deployment of a padded bandaging technique to enable ulcer healing. We also introduce a proactive bandaging approach to reduce the likelihood of pressure ulcer formation. Second, we define phenotypes that distinguish between foot injuries resulting from self-mutilation (autotomy) from those caused by incidental traumatic injury secondary to sensori-motor damage. Finally, we detail an effective strategy to reduce the usage of Elizabethan collars; through a gradual weaning protocol, their usefulness in preventing autotomy is retained, while their propensity to impede rabbit grooming and cause abrasion-injury to the neck region is minimized. Conclusions We suggest that application of these methods offer a practical and systematic approach to avoid adverse side effects associated with rabbit sciatic nerve damage, enabling improved animal welfare and scientific outcomes in a powerful nerve injury model.

"Getting Used to Each Other": Immigrant Youth's Family Reunification Experiences

Suarez-Orozco, Carola,Kim, Ha-Yeon,Bang, Hee-Jin Korean Association of Child Studies 2011 Child studies in Asia-Pacific context Vol.1 No.1

Many immigrant youth and their families undergo painful separations and complicated reunification experiences. Using data from the Longitudinal Immigrant Student Adaptation (LISA) study, a 5-year longitudinal, mixed-methods study of newcomer youth to the U.S., we examine the impact of lengthy family separations on youth's mental health and their perceived family conflict. Quantitative analyses demonstrate that longer separations positively predict higher psychological symptoms and family conflict, particularly for girls over a sustained period of time. Qualitative analyses of parent and child responses provide insights into the family reunification experiences.

Paola Romero-Orozco,원부연,조태오 한국환경생물학회 2023 환경생물 : 환경생물학회지 Vol.41 No.4

Laurencia is a red algal genus that was described by J.V. Lamouroux in 1813. The main characteristics of this genus have been known as the presence of four pericentral cells in an axial segment, secondary pit connections between adjacent epidermal cells, and the presence of corps en cerise in both epidermal and trichoblast cells. Additionally, the tetrasporangia are arranged in a parallel manner, and male branches feature terminal cup-shaped spermatangial pits. Currently, sixteen Korean Laurencia species have been reported based on their morphological characteristics. In this study, Laurencia decussata and L. pacifica have been added as new records to the Korean algal flora based on a combination of morphological observations and molecular analyses of rbcL sequences. Laurencia decussata has expanded from Australia and New Zealand to Korea, while the distribution of L. pacifica has expanded from USA and Mexico to Korea.

Obesity is a chronic disease associated with different metabolic diseases as well as alterations in immune cell function. It is characterized by a chronic systemic low grade inflammation. There are several studies demonstrating the influence of obesity on the impaired immune response to infection. However, it is not completely clear whether the obese environment influences the development or maintenance of the immune response against infections. The aim of this study was to determine how obesity induced by a high-fat diet affects the immune response to an early oral Salmonella infection. Four groups of mice were kept in separate cages. Two of these designated as controls, fed with a normal diet; whereas other two groups were fed with a high fat diet for 10 weeks. Some mice were used for Salmonella oral infection. After 7 days of oral infection with S. Thypimurium the proportions of spleen cell subsets expressing activation markers in normal diet and HFD obese mice were stained with monoclonal antibodies and analyzed by flow cytometry. Also, mRNA levels of different cytokines were quantified by RT-PCR. It was found that obesity affects the function of the immune system against an early oral Salmonella infection, decreasing NK cells, altering the expression of activation molecules as well as cytokines mRNA levels. Interestingly, the expression some activation molecules on T lymphocytes was reestablished after Salmonella infection, but not the CD25 expression. Immune alterations could lead to immunosuppression or increased susceptibility to infections in HFD obese mice.

This study aimed to evaluate the influence ofgermination on the content of protein, lipids, fiber, ashes,tryptophan, vitamin C, total phenolic and total flavonoidcompounds, as well as on the protein digestibility andantioxidant activity of chia seeds germinated for 1, 2, 3,and 4 days. The results showed that germination for 2 daysaugmented the protein content of chia seeds by 13% whilefiber, tryptophan, total phenolic and flavonoid contentsincreased by 46%, 93%, 300%, and 197%, respectively,after 4 days of germination. Vitamin C was not detected indry seeds but increased up to 2.33 mg/100 g at fourth dayof germination. The antioxidant capacity increasedapproximately 100% but protein digestibility decreased by14% at day 4 of germination. Germination can be a goodmethod to increase the nutritional and nutraceuticalpotential of chia seed for its use in the design of functionalfoods.
