Pharmacotherapeutic potential of Vitis vinifera(grape) in age-related neurological diseases / Potencial farmacoterapéutico de Vitis vinifera(uva) en enfermedades neurológicas asociadas a la edad

Age-related neurological disorders (ANDs), including neurodegenerative diseases, are complex illnesses with an increasing risk with advancing years. The central nervous system's neuropathological conditions, including oxidative stress, neuroinflammation, and protein misfolding, are what define ANDs. Due to the rise in age-dependent prevalence, efforts have been made to combat ANDs. Vitis viniferahas a long history of usageto treat a variety of illness symptoms. Because multiple ligand sites may be targeted, Vitis viniferacomponents can be employed to treat ANDs. This is demonstrated by the link between the structure and action of these compounds. This review demonstrates that Vitis viniferaand its constituents, including flavonoids, phenolic compounds, stilbenoidsandaromatic acids, are effective at reducing the neurological symptoms and pathological conditions of ANDs. This is done by acting as an antioxidant and anti-inflammatory. The active Vitis vinifera ingredients have therapeutic effects on ANDs, as this review explains.

Las enfermedades neurológicas asociadas a la edad (AND, por su sigla en inglés) incluyendo las enfermedades neurodegenerativas, son enfermedades complejas con un riesgo creciente con la edad. Las condiciones neuropatológicas del sistema nervioso central, que incluyen el estrés oxidativo, la neuro inflamación, y el plegado erróneo de proteínas, son lo que define las AND. Debido al aumento en la prevalencia dependiente de la edad, se han hecho esfuerzos para combatir las AND. Vitis vinifera tiene una larga historia de uso para el tratamiento de síntomas. Puesto que puede hacer objetivo a muchos sitios ligando, los componentes de Vitis viniferase pueden utilizar para tratar AND. Esto se demuestra por el vínculo entre la estructura y la acción de estos compuestos. Esta revisión demuestra que la Vitis viniferay sus constituyentes, incluídos los flavonoides, componentes fenólicos, estilbenoides, y ácidos aromáticos, son efectivos para reducir los síntomas neurológicos y las condiciones patológicas de AND. Esto se produce por su acción como antioxidante y antiinflamatorio. Los ingredientes activos de Vitis vinifera tienen efectos terapéuticos en AND, y esta revisión lo explica.

Effects of supportive counseling using a positive psychology approach on coping patterns among pregnant women with nausea and vomiting.

BACKGROUND: Pregnancy nausea and vomiting (NVP) are associated with a wide range of physical and mental changes in the mothers and could affect their adaptation to pregnancy. There is a gap of knowledge regarding the effectiveness of a positive psychology approach counselling on improving coping patterns in women with NVP. OBJECTIVE: This study aimed to determine the effect of supportive counselling with a positive psychology approach on improving coping patterns in women with NVP. METHOD: The current study was a randomized controlled trial on 60 pregnant women who experienced nausea and vomiting in Zanjan a province in the northwest of Iran, 2020-2021. Using four-block random sampling, eligible women were randomly assigned to the intervention and control groups. According to the Seligman protocol, the intervention group received supportive counselling in six sessions of 45 min3 times a week. The revised prenatal coping inventory (Nu PCI) was used to collect data and analyzed using Chi-square, repeated measures ANOVA, and MANOVA at a 95% confidence level. RESULTS: In the counseling group, the mean (SD) of a total score of coping with pregnancy before the intervention was 6.11 (1.31) which increased to 8.40 (1.03) in 4 weeks after the intervention. Based on the MANOVA test with adjusting the number of pregnancies, the mean total score of coping with pregnancy was statistically significant 4 weeks after the intervention compared with the control group (Adjusted mean difference (AMD) = -1.84, CI95% -2.36, -1.32, p = 0.001). CONCLUSION: The use of positive psychology in supportive counselling improved the coping of mothers suffering from nausea and vomiting during pregnancy. It is recommended that this approach be incorporated into prenatal care to promote the health of pregnant women. TRIAL REGISTRATION: The study was registered at the Iranian Registry of Clinical Trials website under the code IRCT20150731023423N17 . Registration date: 2020-10-31, Expected recruitment start date: 2020-11-01. IRCT Id: IRCT20150731023423N17.

Serologic and Molecular Evidence of Widespread Infection of Avian Hepatitis E Virus in Poultry Farms of Iran.

Hepatitis-splenomegaly syndrome is caused by avian hepatitis E virus (aHEV), a nonenveloped, single-stranded RNA virus. The economic importance of this disease in the poultry industry is due to the decline in egg production (10%-40%) and the rise in mortality (1%-4%). In the present study, 1540 serum samples from 33 broiler breeder flocks were analyzed by an enzyme-linked immunosorbent assay for the presence of an anti-aHEV antibody. In addition, a diagnostic nested reverse transcriptase-PCR was done on all farm samples. In the serologic study, 66.7% (22/33) of the flocks and 28.5% (439/1540) of the chickens were positive. The molecular study showed that three farms were positive, and PCR products were observed for the conserved regions of the aHEV helicase and capsid virus genes as 386 bp and 242 bp, respectively. It should be noted that clinical and pathologic symptoms including decreased egg production, enlarged livers and spleens, and a slight rise in mortality rate were observed in eight farms. To our knowledge, this is the first documented study on the aHEV identification and its antibody detection in broiler breeder farms in Iran.

Evidencia serológica y molecular de una infección diseminada del virus de la hepatitis E aviar en granjas avícolas en Irán. El síndrome de hepatitis-esplenomegalia es causado por el virus de la hepatitis E aviar (aHEV), un virus de ARN de cadena simple sin envoltura. La importancia económica de esta enfermedad en la industria avícola se debe a la disminución en la producción de huevo (10%-40%) y al aumento de la mortalidad (1%-4%). En el presente estudio, se analizaron 1540 muestras de suero de 33 parvadas de reproductores pesados mediante un ensayo de immunoabsorción con enzimas ligadas para determinar la presencia de anticuerpos contra el virus de la hepatitis E aviar. Además, se realizó un método de transcripción reversa y PCR anidado de diagnóstico en todas las muestras de la granja. En el estudio serológico, el 66.7% (22/33) de las parvadas y el 28.5% (439/1540) de los pollos fueron positivos. El estudio molecular mostró que tres granjas fueron positivas, y se observaron productos de PCR para las regiones conservadas de los genes del virus de la cápside y de la helicasa del virus de la hepatitis E aviar con tamaños de 386 pb y 242 pares de bases, respectivamente. Cabe señalar que en ocho granjas se observaron signos clínicos y patológicos como disminución de la producción de huevos, agrandamiento del hígado y del bazo y un ligero aumento en la tasa de mortalidad. Hasta donde se conoce, este es el primer estudio documentado sobre la identificación del virus de la hepatitis E aviar y la detección de anticuerpos en granjas de pollos de engorde en Irán.
