A Simplified Splint Tubing Technique of Heterotopic Heart Transplantation in Rat

Background: Heterotopic Heart Transplantation (HHT) in rats has been established for the study of transplantation immunology. Our goal was to describe a Splint Tubing Technique (STT) for cervical HHT in rats. Methods: Wistar-Furth rats were performed in HHT using STT and Suture Technique (ST). With STT, the surgical procedure connected with the recipient external jugular vein (EJV), Common Carotid Artery (CCA) to the donor Pulmonary Artery (PA), Ascending Aorta (AA) using an 18G and 20G cuff, respectively. The surgical success rate and operation time was recorded. Graft function was assessed by pulse palpation and echocardiography. The cardiac pathology was analyzed by HE staining. TUNEL and western blotting were used to measure apoptosis in each rat. Results: Averaged total operation time using ST was much longer than STT. The success rate of STT was 83.3%, which showed significantly higher than ST (55.0%). HE staining of STT group showed the same acute rejection compared to ST group. Same tendency of apoptosis in two groups was detected by TUNEL and western blotting. Conclusions: Our simplified STT for HHT in rats is an easy, convenient, stable, and reliable method. It simplified the rat HHT procedure, shortened operation time, reduced surgical difficulty, improved technical success rate.

The Effect of Nitrogen and NPS Fertilizer Rates and Inter-row Spacing on the Growth and Yield of Head Cabbage (Brassica oleracea L.) under Irrigation in Bako, Western Oromia, Ethiopia

Head cabbage is a popular leafy vegetable consumed all over the world. However, a number of factors, such as diminished soil fertility and poor agronomic practices, frequently restrict the crop’s production and productivity. A study was conducted at Bako Agricultural Research Center, under surface irrigation, during the cropping seasons of 2022 and 2023 for two years, to determine the effects of three levels of inter-row spacing, Nitrogen from urea, and Phosphorus from (NPS), were laid out in a randomized block design with three replications in a 3x3x3 factorial arrangement. The results analysis of variance indicated that the inter-row spacing of 55 cm had a substantial effect on the marketable yield (27483 kg ha-1) and total yield, (31842 kg ha-1). Likewise, 69 N ha-1 fertilizer rates from urea gave the highest marketable yield of 27861 kg ha-1 and total cabbage yield of 31824 kg ha-1. The partial budget analysis across year showed the highest net benefit of, 274720.0 birr obtained. Therefore, application 69 N ha-1 fertilizers and 100 kg ha-1 NPS with inter-row spacing of 55 cm under irrigation can be recommended for the production of head cabbage in study area and similar agroecology ecology based on the study’s findings

Optimizing Drug Distribution Logistics in the Community of Madrid

Health-related services, and specifically drugs, are one of the most important economic activities in modern societies. Drugs, as a final medical product, constitute the basis for improving the quality of health services. In this article, we propose as a general working hypothesis that better rationalization in the logistics distribution of drugs, through a combination of an optimal location of distribution centers, transport routes, and a rational selection of means of transport, could positively influence both the perceived quality of care and the quality of drugs by the user. In addition, we study how to reduce energy consumption, the carbon footprint (CO2 ), the risk of non-supply, refrigeration, and monitoring costs, and, ultimately, the final cost of centralized drug distribution. On this basis, we have built a model taking all the data from the geographic locations of more than 2,500 pharmacies in the Community of Madrid, and with the help of the R program, the data have been classified into ‘clusters’ using minimum distances and giving different center solutions depending on the number of clusters.

Effect of Different Environmental Exposures on Retinal Arteriolar and Venular Diameters in Healthy Individuals and Those with Increased Cardiovascular Risk: A Systematic Review

Context: Fundus scanning has emerged as a non-invasive way to estimate the risk for cardiovascular diseases. Research suggests that environmental risk factors, such as diet and smoking, influences the structure of the retinal microvasculature, particularly the central retinal arteriolar and venular equivalents (CRAE & CRVE). Objective: This systematic review provides an updated overview of existing research on the effect of diet, smoking, physical activity, air pollution, alcohol consumption and miscellaneous exposures on retinal microvasculature in healthy individuals and people at risk for cardiovascular disease. Data Sources: The databases PubMed, Web of Science, OVID were used as data sources and were last accessed September 12nd 2024. Study Selection: Peer-reviewed studies investigating the effect of any type of environmental exposure on retinal microvessel diameters in healthy individuals and people at risk for cardiovascular disease were included. Data Extraction: Relevant information and outcomes of 88 studies were extracted. Methodological quality was assessed using the NIH quality assessment tool. Data from each included study was extracted by two independent reviewers, while a third reviewer checked for consensus. Conclusions: Several dietary components, including numerous phytochemicals or fish oils have beneficial effects while other components (high glycemic index products, red meat) have deleterious effects on the retinal microvasculature. There was no unilateral association between smoking and CRAE nor CRVE. A decrease in retinal vessel diameters is induced by isometric exercise, whereas endurance exercise causes increased diameters. Fine Particulate Matter (PM2.5) exposure induces decreases in CRAE and CRVE. Further research is necessary to attain scientific consensus on the effects of alcohol consumption on the retinal microvasculature.

High-performance Liquid Chromatography Method Development and Validation for the Determination of Ellagic Acid in Topical Cream Formulations as Hyperpigmentation Treatment

Skin hyperpigmentation is a dermatological condition that cause a change in skin coloration. In this condition an overproduction of melanin happens in skin melanocytes. Ellagic Acid (EA) is a pharmaceutical substance that found in many fruits and plants which is quite useful to apply in skin products due to its antityrosinase and antioxidant activity. In this study a topical cream of EA was prepared and methanol was employed as extraction solvent to determine the amount of EA in the formulation. For this aim we have developed and validated a High-Performance Liquid Chromatography (HPLC) method in order to evaluation the amount of EA in cream. The developed method was validated against criteria such as linearity, specificity, precision, accuracy, Limit of Detection (LOD) and Limit of Quantification (LOQ) due to the International Council for Harmonization (ICH) guidelines, Q2. Our results showed high specificity, linearity (R2=0.9973), sensitivity and acceptable precision and accuracy rate. By our developed HPLC method the concentration of EA in topical cream was calculated, and it was found to be 9.81 mg/ml. Also, this method can be used for EA determining in lipid nanoparticles, such as liposomes, solid lipid nanoparticles (SLNs) and Nanostructured Lipid Carriers (NLCs)For more information, visit the full study through below link.

Knuckle-Dimple-Dimple-Dimple Sign

 

A 15-year-old girl, second in birth order from consanguineous marriage, presented with progressive weight gain over five years. Upon examination, she had a round face, almond-shaped eyes, acanthosis nigricans, short stature (height SDS -2.5), and obesity (BMI 30.6 kg/m). Her hands and feet showed short, stubby fingers with positive Archibald sign, characterized by a “knuckle-dimple-dimple-dimple” pattern (Figure 1a). Her mother and maternal grandmother shared similar hand features, suggesting a familial inheritance. Radiographic evaluation of the hands revealed Type E brachydactyly based on the Tamtamy classification, with shortening of 3rd, 4th and 5th metacarpals and phalanges (Figure 1b). Biochemical testing showed normal calcium, phosphate, and Parathyroid Hormone (PTH) levels, ruling out true hypoparathyroidism. In presence of normal regulation of mineral ion homeostasis, short stature, obesity and typical Albright’s Hereditary Osteodystrophy (AHO) feature, diagnosis of pseudopseudo hypoparathyroidism was stablished. This rare autosomal dominant disorder is caused by GNAS gene mutation.
