AIM To examine the association between weekend alcohol consumption and the biochemical and histological alterations at two different concentrations of alcohol in both genders in rats.METHODS Wistar rats weighing 170-200 g were divided into groups as follows:(1) Control groups; and(2) weekend alcohol-consumption group: 2 d/weekly per 12 wk, at two different concentrations:(1) Group of males or females with a consumption of a solution of alcohol at 40%; and(2) group of males or females with a consumption of a solution of alcohol at 5%. At the end of the experiment, serum and liver samples were obtained. The following enzymes and metabolites were determined in serum: Alanine Aminotransferase(ALT), Aspartate Aminotransferase(AST), Lactate Dehydrogenase, and Gamma-Glutamyltransferase, and glucose, triglycerides, cholesterol, bilirubin, and albumin. Liver samples from each group were employed to analyze morphological abnormalities by light microscopy.RESULTS In all of the weekend alcohol-consumption groups, AST activity presented a significant, 10-fold rise. Regarding ALT activity, the groups with weekend alcohol consumption presented a significant increase that was six times greater. Bilirubin levels increased significantly in both groups of females. We observed a significant increase in the parameters of fatty change and inflammation due to weekend alcohol consumption. Only the group of females that consumed alcohol at 40% presented slight hepatocel ular disorganization CONCLUSION The results obtained herein provide solid evidence that weekend alcohol consumption gives rise to liver damage, demonstrated by biochemical and histological alterations, first manifested acutely, and prolonged weekend alcohol consumption can cause greater, irreversible damage.

The liver is one of the most important organs in the body,performing a fundamental role in the regulationof diverse processes,among which the metabolism,secretion,storage,and detoxification of endogenous and exogenous substances are prominent.Due to these functions,hepatic diseases continue to be among the main threats to public health,and they remain problems throughout the world.Despite enormous advances in modern medicine,there are no completely effective drugs that stimulate hepatic function,that offer complete protection of the organ,or that help to regenerate hepatic cells.Thus,it is necessary to identify pharmaceutical alternatives for the treatment of liver diseases,with the aim of these alternatives being more effective and less toxic.The use of some plants and the consumption of different fruits have played basic roles in human health care,and diverse scientific investigations have indicated that,in those plants and fruits so identified,their beneficial effects can be attributed to the presence of chemical compounds that are called phytochemicals.The present review had as its objective the collecting of data based on research conducted into some fruits(grapefruit,cranberries,and grapes)and plants[cactus pear(nopal)and cactus pear fruit,chamomile,silymarin,and spirulina],which are consumed frequently by humans and which have demonstrated hepatoprotective capacity,as well as an analysis of a resin(propolis)and some phytochemicals extracted from fruits,plants,yeasts,and algae,which have been evaluated in different models of hepatotoxicity.

AIM: To evaluate the effect of an extract of Geranium schiedeanum(Gs) as a hepatoprotective agent against ethanol(Et OH)-induced toxicity in rats. METHODS: Male Wistar rats weighing 200-230 g were subjected to a 70% partial hepatectomy(PH); they were then divided into three groups(groups 1-3). During the experiment, animals in group 1 drank only water. The other two groups(2-3) drank an aqueous solution of Et OH(40%, v/v). Additionally, rats in group 3 received a Gs extract daily at a dose of 300 mg/kg body weight intragastically. Subsequently, to identify markers of liver damage in serum, alanine aminotransferase, aspartate aminotransferase, albumin and bilirubin were measured by colorimetric methods. Glucose, triglyceride and cholesterol concentrations were also determined. In addition, oxidative damage was estimated by measuring lipid peroxidation [using thiobarbituric-acid reactive substances(TBARS)] in both plasma and the liver and by measuring the total concentration of antioxidants in serum and the total antioxidant capacity in the liver. In addition, a liver mass gain assessment, total DNA analysis and a morpho-histological analysis of the liver from animals in all three groups were performed and compared. Finally, the number of deaths observed in the three groups was analyzed.RESULTS: Administration of the Geranium shiedeanum extract significantly reduced the unfavorable effect of ethanol on liver regeneration(restitution liver mass: PHEt OH group 60.68% vs PH-Gs-Et OH group 69.22%). This finding was congruent with the reduced levels of hepatic enzymes and the sustained or increased levels of albumin and decreased bilirubin in serum. The extract also modified the metabolic processes that regulate glucose and lipid levels, as observed from the serum measurements. Lower antioxidant levels and the liver damage induced by Et OH administration appeared to be mitigated by the extract, as observed from the TBARs(PH-Et OH group 200.14 mmol/mg vs PH-Gs-Et OH group 54.20 mmol/mg; P < 0.05), total status of antioxi

Insulin:A connection between pancreaticβcells and the hypothalamus

World Journal of Diabetes 2023年第2期14卷 76-91页

Insulin is a hormone secreted by pancreaticβcells.The concentration of glucose in circulation is proportional to the secretion of insulin by these cells.In target cells,insulin binds to its receptors and activates phosphatidylinositol-3-kinase/protein kinase B,inducing different mechanisms depending on the cell type.In the liver it activates the synthesis of glycogen,in adipose tissue and muscle it allows the capture of glucose,and in the hypothalamus,it regulates thermogenesis and appetite.Defects in insulin function[insulin resistance(IR)]are related to the development of neurodegenerative diseases in obese people.Furthermore,in obesity and diabetes,its role as an anorexigenic hormone in the hypothalamus is diminished during IR.Therefore,hyperphagia prevails,which aggravates hyperglycemia and IR further,becoming a vicious circle in which the patient cannot regulate their need to eat.Uncontrolled calorie intake induces an increase in reactive oxygen species,overcoming cellular antioxidant defenses(oxidative stress).Reactive oxygen species activate stress-sensitive kinases,such as c-Jun Nterminal kinase and p38 mitogen-activated protein kinase,that induce phosphorylation in serine residues in the insulin receptor,which blocks the insulin signaling pathway,continuing the mechanism of IR.The brain and pancreas are organs mainly affected by oxidative stress.The use of drugs that regulate food intake and improve glucose metabolism is the conventional therapy to improve the quality of life of these patients.Currently,the use of antioxidants that regulate oxidative stress has given good results because they reduce oxidative stress and inflammatory processes,and they also have fewer side effects than synthetic drugs.

“I Felt Defeated. I Felt Helpless”: Social Determinants of Health Influencing the Cancer Survivorship of a Young Latina Mother

引用

Journal of Cancer Therapy 2022年第7期13卷 440-449页

作者： Adriena Hernandez Clara L. Reyes isela Garcia Rebecca L. Palacios Department of Health Promotion Sciences The University of Arizona Tucson AZ USA Department of Public Health Sciences New Mexico State University Las Cruces NM USA

Social determinants of health (SDOH) contribute to cancer disparities among young Latina women (<50 years) residing in the counties along the US-Mexico border. These SDOH are particularly burdensome to young Latina mothers diagnosed with cancer while they are raising school-age children. Conexiones, a culturally adapted program designed to improve mother and child adjustment to maternal cancer, was piloted with diagnosed Latina mothers residing in border counties in New Mexico and Texas. The purpose of this case analysis was to highlight the SDOH affecting a young Latina mother’s cancer survivorship in the U.S.-Mexico border region. The participant’s Conexiones education sessions were recorded, transcribed, translated to English, back translated to Spanish to establish accuracy, and inductively coded. The participant’s baseline survey indicated she was a young (<50 years), married, Spanish-speaking Latina mother diagnosed with breast cancer while raising a teenage daughter. Seventeen SDOH themes affecting the participant’s cancer experience were identified in the cancer-related emotional triggers she reported across five Conexiones sessions. These themes were organized using Yanez’s conceptual model of determinants of cancer outcomes in Hispanics (i.e., socioeconomic, healthcare, cultural context, and psychosocial). Findings provide direction for cultural adaptations of evidence-based programs.

Sexually transmitted infections (STIs) and unwanted pregnancy (UP) are becoming a problem that affects significantly the younger segment of the population so, not only in the aspect of health, but in the development of its future life both emotional and school and work. Despite easy access to information, young people still have risky sexual practices. This research highlights protective practices with the aim of developing information and training tools that help them avoid risky behaviors that lead to dangerous situations in health and its future. It was a descriptive study with students who have recently entered of the Faculty of Medicine enrolled in school cycle in 2015 in the bachelor’s degree in Medicine and surgery, Nutrition and dietetics, and Rehabilitation programs who agreed to participate by letter of informed consent to respond to the Instrument for the Evaluation of Psychological Variables and Sexual Risk Behaviors. There were 221 participants, 166 in Medicine and surgery, 28 in Nutrition and dietetics, and 27 in Rehabilitation with an average of 18.6 years, 51% male and 49% female. A protective behavior was not having had sex with penetration (72.3%), due to wanting to have them with whom they are in love and to avoid STIs more frequently in female;another protective behavior was not having had oral sex with occasional partners or unprotected sex workers (15.4%);the reasons were to have wanted to use and that the couple asked him to use it, to avoid sexually transmitted infections because the couple’s sexual history is unknown. Regarding the likelihood of having sexual penetration (SP), participants who have not had it were found that: the men had less possibility to inquire about their partner’s sexual history, to reject the proposal to have SP and to refuse caresses in sensitive areas of the woman’s body;when asked about the likelihood of asking your partner to use a condom in their sexual relations, both men and women agreed that it would be quite likely that they would do so, more frequently in

Various microorganisms live in association with different parts of plants and can be harmful,neutral,or beneficial to plant health.Some microbial inhabitants of plants can control plant diseases by contesting with,predating on,or antagonizing plant pathogens and by inducing systems for plant defense.A range of methods,including plant growth-promoting microorganisms(PGPMs)as biological control agents(BCAs)(BCA-PGPMs)are used for the biological management and control of plant pathogens.Some BCAs interact with plants by inducing resistance or priming plants without direct interaction with the pathogen.Other BCAs operate via nutrient competition or other mechanisms to modulate the growth conditions for the pathogen.Generally,PGPMs can be applied alone or together with other chemicals or carriers to control various crop diseases.This review highlights the effective types of BCA-PGPMs and their applications,roles,carrier based-formulations,and responses to rice(Oryza sativa L.)pathogens.Future plant disease management prospects are promising,and growers’increasing demand for BCA-PGPM products can be exploited as an effective approach to the management of plant diseases,as well as to improve yield,environmental protection,biological resources,and agricultural system sustainability.

Acta Oceanologica Sinica 2021年第9期40卷 53-65页

作者： Marcelino Ruiz-Dominguez Casimiro Quinonez-Velazquez Dana isela Arizmendi-Rodriguez Victor Manuel Gomez-Munoz Manuel Otilio Nevarez-Martinez Facultad de Ciencias del Mar Universidad Autonoma de SinaloaMazatlan 82000Mexico Instituto Politecnico Nacional Centro Interdisciplinario de Ciencias MarinasLa Paz 23000Mexico Instituto Nacional de Pesca y Acuacultura Centro Regional de Investigacion Pesquera Unidad GuaymasGuaymas 85400Mexico

In recent years,the small pelagic fishery on the Pacific northwest coast of Mexico has significantly increased fishing pressure on thread herring Opisthonema spp.This fishery is regulated using a precautionary approach(acceptable biological catch(ABC)and minimum catch size).However,due to fishing dynamics,fish aggregation habits and increased fishing mortality,periodic biomass assessments are necessary to estimate ABC and assess the resource status.The Catch-MSY approach was used to analyze historical series of thread herring catches off the western Baja California Sur(BCS,1981–2018)and the Gulf of California(GC,1972–2018)to estimate exploitable biomass and target reference points in order to obtain catch quotas.According to the results,in GC,the maximum biomass reached in 1972(at the beginning of fishery)and minimum biomass reached in 2015;the estimated exploitable biomass for 2019 was 42.2×10^(4) t;and the maximum sustainable yield(MSY)was 15.4×10^(4) t.In the western BCS coast,the maximum biomass was reached in 1981(at the beginning of fishery)and minimum biomass was reached in 2017;the estimated exploitable biomass for 2019 was 3.2×10^(4) t;and the MSY was 1.2×10^(4) t.Both stocks showed a decrease in biomass over the past years and were currently near to point of full exploitation.The results suggest that the use of the Catch-MSY method is suitable to obtain annual biomass estimates,in order to establish an ABC,to know the current state of the resource,and to avoid overcoming the potential recovery of the stocks.

Health 2011年第3期3卷 159-161页

作者： María Elena Soto Virgilia Soto Julia isela Martín Sandría Ricardo Gamboa Claudia Huesca 不详

Takayasu’s arteritis (TA), of unknown etiology, has been related with Mycobacterium tuberculosis infection. The published cases are controversial. A 29- year-old man died, prolapse of the aortic valve and unspecific arteritis were demonstrated at necropsy. Our objective was to search in the fresh aortic tissues, the infectious agent of tuberculosis through culture, as well as by performing histopathology and searching by the molecular study, sequences of genes associated to micobacteria and Ziehl’s stain. Results. The bacillus of tuberculosis was observed by the Ziehl’s stain and the sequences of insertion IS6110 gene were identified. Our findings support the relation of TA with possible tuberculosis infection.Conclusion. The possibility that Takayasu’s arteritis is an extra pulmonary tu-berculosis must be explored.

Dengue is one of the most prominent tropical epidemic diseases present in the Rio de Janeiro city and Southeast part of Brazil, due to the widespread conditions of occurrence of the dengue vector, the mosquito Aedesaegypti, such as high-temperature days interlaced with afternoon or nocturnal rainstorms in summer. This work has the objective of investigating the relationships between variabilities of the El Ni?o-South Oscillation (ENSO) and greater epidemics of dengue in Rio de Janeiro city. To accomplish this goal, the analysis and signal decomposition by cross-wavelet transform (WT) was applied to obtain the cross variability associated with variations of power and phase of both signals by characteristic periods and along with the time series. Data considered in the analysis are (the decimal logarithm of normalized value) of the monthly available notifications of dengue worsening, provided by the public health system of Brazil, and the Southern Oscillation Index (SOI) Ni?o 3.4 data, provided by the National Oceanic and Atmospheric Administration (NOAA), in the period 2000-2017. A maximum cross-wavelet power close to 0.45 was obtained for the representative period of 1 year and also to periods between 3 and 4 years, associated with the positive phase of the SOI index (i.e. , La Ni?a) or with a transition to the positive phase. The evolution of the combined variability of SOI and dengue can be expressed by progressive differences in phase along the time, eventually resulting in yielding phases (i.e., La Niña-Dengue epidemic).
