"An unprecedented occurrence: a case report of pulmonary hypertension manifestation in Donohue syndrome".

INTRODUCTION: Donohue syndrome (DS), also referred to as leprechaunism, is a remarkably uncommon autosomal recessive disorder that primarily affects the endocrine system. Its incidence rate is exceedingly low, with only 1 case reported per 4 million live births. The syndrome is distinguished by a series of characteristic clinical features. CASE PRESENTATION: We present a case of a twenty-month-old male with DS who experienced a range of dysmorphic and clinical features with the involvement of multiple systems. These features include skin hyperpigmentation, hypertrichosis, distinct facial features, abdominal distension, and microcephaly, with the involvement of the endocrine, renal, respiratory, and cardiac systems. CONCLUSION: The primary features of DS involve severe insulin resistance and growth abnormalities, the association with pulmonary hypertension (PHTN) has not been reported before. This finding adds more complexity to the condition. To the best of the author's knowledge, this is the first report for a patient with DS who has PHTN. Further investigation is required since the mechanisms behind the development of PHTN in DS are not entirely understood. Shedding light on this association will contribute to better management strategies and outcomes for affected patients.

In vitro anti-HSV1 activity of aqueous extract of Areca catechu L.

Background and Objectives: HSV-1 is known as a very contagious virus and the main cause of cold sores or fever blisters. Herein, the aqueous extract of Areca catechu L. was evaluated for its anti-HSV-1 activity, compared to the standard control (acyclovir). Also, the effect of extract on the expression of UL46 and US6 genes that accumulate late in viral infection, was studied. Materials and Methods: The aqueous extract was obtained by the maceration of powdered plant in boiling water. Its antiviral activity was evaluated on Vero cells infected with HSV-1 at different times: 2 h pre-infection, simultaneous infection, and 4 h post-infection, using MTT assay. The effect of extract on the expression of genes was investigated with quantitative real-time PCR. Results: The aqueous extract of A. catechu induced the inhibition of infection with the IC50 value of 110.52 ± 1.36 µg/ml. Also, it reduced the expression of UL46 when it was added 2 h pre-infection at 100 µg/ml. Moreover, reduction of expression of US6 was observed at the same concentration when the extract was used simultaneously with the occurrence of infection and 4 h post-infection. Conclusion: A. catechu can be considered an essential element of natural-based anti-HSV-1 agents.

Synthesis of novel hybrids of 1,2,3-triazoles-hydrazone: targeting cholinesterases and Alzheimer's related genes.

Aim: A new series of 1,2,3-triazole-hydrazone derivatives were developed to evaluate their anti-Alzheimer's activity. Materials & methods: All compounds were screened toward cholinesterases via the modified Ellman's method. The toxicity assay on SH-SY5Y cells was performed using the MTT assay, and the expression levels of GSK-3α, GSK-3ß, DYRK1 and CDK5 were assessed in the presence of compounds 6m and 6p. Results: 6m and 6p; acting as mixed-type inhibitors, exhibited promising acetylcholinesterase and butyrylcholinesterase inhibitory activity, respectively. 6m demonstrated no toxicity under tested concentrations on the SH-SY5Y cells and positively impacted neurodegenerative pathways. Notably, 6m displayed a significant downregulation in mRNA levels of GSK-3α, GSK-3ß and CDK5. Conclusion: The target compounds could be considered in developing anti-Alzheimer's disease agents.

Assessing breast self-examination knowledge and practices among women in Iraq: A cross-sectional study.

Background and Aims: The present study aims to shed light on the knowledge, attitude, and practice of breast self-examination with breast cancer (BC) among female patients in the oncology department of Baghdad Medical City. Methods: This cross-sectional study involved 100 female participants at the Oncology Teaching Hospital in Baghdad Medical City between June 15 and October 15, 2022. Using convenient sampling, the study targeted females aged 30-75, recently or previously diagnosed with BC, admitted for treatment and follow-ups. Results: Regarding the assessment of knowledge, among the surveyed patients, 71 are aware of breast self-examination (BSE), primarily through social media (42 patients). The study also explores the link between BSE and education levels. While Pearson's chi-square shows no significance (0.107), the likelihood ratio suggests a significant association (0.041). Regarding the analysis of attitudes, the study assessment for the reasons for compliance showed that 19 patients cite medical reasons, and 48 patients attribute noncompliance to a lack of knowledge of how to perform BSE. Regarding the examination of practice, high statistical significance is evident in both Pearson's chi-square (0.000) and likelihood ratio (0.000) tests, emphasizing the substantial relationship between the post-diagnosis initiation timing of BSE and its correct execution. Additionally, a statistically significant association exists between performing BSE correctly and discovering BC (p = 0.000). Conclusion: Regarding the assessment of knowledge, our study found high awareness of BSE within the population, primarily through social media and health organizations. Regarding the analysis of attitudes, a notable proportion refrained from practicing BSE, primarily due to a perceived lack of knowledge about the methods. Regarding the examination of practice, the observed significant associations between performing BSE correctly, discovering BC, and the frequency of examinations underscore the pivotal role of consistent and accurate BSE in early detection.

Investigation of anti-Alzheimer's activity of aqueous extract of areca nuts (Areca catechu L): in vitro and in vivo studies / Investigación de la actividad anti-Alzheimer del extracto acuoso de nueces de areca (Areca catechu L): estudios in vitro e in vivo

Alzheimer's disease (AD) is an age-related neurodegenerative disorder. Sever cognitive and memory impairments, huge increase in the prevalence of the disease, and lacking definite cure have absorbed worldwide efforts to develop therapeutic approaches. Since many drugs have failed in the clinical trials due to multifactorial nature of AD, symptomatic treatments are still in the center attention and now, nootropic medicinal plants have been found as versatile ameliorators to reverse memory disorders. In this work, anti-Alzheimer's activity of aqueous extract of areca nuts (Areca catechu L.) was investigated via in vitro and in vivo studies. It depicted good amyloid ß (Aß) aggregation inhibitory activity, 82% at 100 µg/mL. In addition, it inhibited beta-secretase 1 (BACE1) with IC50 value of 19.03 µg/mL. Evaluation of neuroprotectivity of the aqueous extract of the plant against H2O2-induced cell death in PC12 neurons revealed 84.5% protection at 1 µg/mL. It should be noted that according to our results obtained from Morris Water Maze (MWM) test, the extract reversed scopolamine-induced memory deficit in rats at concentrations of 1.5 and 3 mg/kg.

La enfermedad de Alzheimer (EA) es un trastorno neurodegenerativo relacionado con la edad. Los severos deterioros cognitivos y de la memoria, el enorme aumento de la prevalencia de la enfermedad y la falta de una cura definitiva han absorbido los esfuerzos mundiales para desarrollar enfoques terapéuticos. Dado que muchos fármacos han fallado en los ensayos clínicos debido a la naturaleza multifactorial de la EA, los tratamientos sintomáticos siguen siendo el centro de atención y ahora, las plantas medicinales nootrópicas se han encontrado como mejoradores versátiles para revertir los trastornos de la memoria. En este trabajo, se investigó la actividad anti-Alzheimer del extracto acuoso de nueces de areca (Areca catechu L.) mediante estudios in vitro e in vivo. Representaba una buena actividad inhibidora de la agregación de amiloide ß (Aß), 82% a 100 µg/mL. Además, inhibió la beta-secretasa 1 (BACE1) con un valor de CI50 de 19,03 µg/mL. La evaluación de la neuroprotección del extracto acuoso de la planta contra la muerte celular inducida por H2O2 en neuronas PC12 reveló una protección del 84,5% a 1 µg/mL. Cabe señalar que, de acuerdo con nuestros resultados obtenidos de la prueba Morris Water Maze (MWM), el extracto revirtió el déficit de memoria inducido por escopolamina en ratas a concentraciones de 1,5 y 3 mg/kg.

Investigation of polysaccharide extracts from Iranian and French strains of Agaricus subrufescens against enzymes involved in Alzheimer's disease / Investigación de extractos de polisacáridos de cepas iraníes y francesas de Agaricus subrufescens contra enzimas relevantes para la enfermedad de Alzheimer

In this work, the inhibitory activity of a wide range of polysaccharide extracts from two Iranian and French strains of Agaricus subrufescens were evaluated toward acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Among them, two extracts S9 and S'7 obtained from Iranian and French strains under different extraction conditions showed selective AChE inhibitory activity with IC50 values of 154.63 and 145.43 µg/mL, respectively. It should be noted that all extracts from both strains demonstrated no BChE inhibitory activity. S9 and S'7 were also tested for their effect on amyloid beta (Aß) aggregation, antioxidant activity, and neuroprotectivity. Their activity against Aß aggregation was comparable to that of donepezil as the reference drug but they induced moderate antioxidant activity by DPPH radical scavenging activity and negligible neuroprotectivity against Aß-induced damage.

En este trabajo, se evaluó la actividad inhibitoria de acetilcolinesterasa (AChE) y butirilcolinesterasa (BChE) para varios extractos de polisacáridos de dos cepas iraníes y francesas de Agaricus subrufescens. Los extractos más potentes mostraron valores de IC50 de 154,63 y 145 µg/ml para las cepas iraní (S9) y francesa (S'7), respectivamente, las cuales se obtuvieron de diferentes condiciones de extracción; sin embargo, todos los extractos no mostraron actividad inhibitoria de BChE. Además, S9 y S'7 se probaron para determinar su efecto sobre la agregación de beta-amiloide (Aß), así como su actividad antioxidante y neuroprotectora. Su actividad inhibitoria de la agregación de Aß fue comparable con donepezil, fármaco de referencia, pero indujeron una actividad antioxidante moderada, medida mediante la captación de radicales DPPH, y una neuroprotectora insignificante contra el daño inducido por Aß.

Phthalate contamination of some plants and herbal products / Contaminación de algunas plantas y productos herbales con ftalatos

Phthalate derivatives cause a number of risks to human health and the environment. Essential oil and volatile fractions of some vegetables and herbal products were extracted by hydrodistillation and percolation methods to analyze using gas chromatography and mass spectrometry (GC-MS) for evaluation of phthalate contaminations. The results revealed that four vegetables and all aromatic waters were contaminated by phthalate derivatives including di-n-butyl phthalate (DBP), diisobutyl phthalate and di-(2-ethylhexyl) phthalate (DEHP) (0.1-7.95%). Butylated hydroxytoluene (BHT), a widely used synthetic antioxidant, was also found in the most of the aromatic waters in the range of 3.15-61.3%. In addition, three vegetable samples contained diazinon (0.36-4.61%), an organophosphorus insecticide. Plants and herbal preparations may be contaminated by the absorption of phthalates from contaminated water or soil or by the migration of phthalates from inexpensive recycled plastic. Regarding the widespread use and associated health risks of phthalates, effective quality and safety regulations for herbal products should be implemented with respect to their phthalate content.

Los derivados de ftalato causan una serie de riesgos para la salud humana y el medio ambiente. El aceite esencial y las fracciones volátiles de algunos vegetales y productos a base de hierbas fueron extraídos mediante hidrodestilación y métodos de percolación y luego fueron analizados mediante cromatografía de gases y espectrometría de masas (GC-MS) con el propósito de identificar contaminación con ftalatos. Los resultados revelaron que cuatro productos herbales y todas las aguas aromáticas analizadas estaban contaminadas con derivados de ftalato, incluyendo el ftalato de dibutulo (DBP), ftalato de diisobutilo y ftalato de bis(2-etilhexilo) (DEHP) (0.1-7.95%). El butilhidroxitolueno (BHT), un antioxidante sintético ampliamente utilizado, también se encontró en aguas aromáticas en el rango de 3.15- 61.3%. Además, tres muestras vegetales contenían diazinón (0.36-4.61%), un insecticida organofosforado. Las plantas y las preparaciones herbales pueden ser contaminadas a partir de absorción de ftalatos del agua o el suelo contaminados o por la migración de ftalatos desde plástico reciclado de bajo costo. Con respecto al uso generalizado y los riesgos asociados a la salud de los ftalatos, deben implementarse normas efectivas de calidad y seguridad para los productos a base de hierbas con respecto a su contenido de ftalato.
