Maize is an economically important crop worldwide. As the world population increases, there is a great need to develop high yielding and stress resistant maize varieties. To provide a future platform for maize improvement, we tested mature embryos as alternative explants for the regeneration of three economically important maize inbred lines: CML331, CML442 and CML444.

Gestational diabetes mellitus (GDM) is associated with an increased maternal and fetal risk of complications. Other than lifestyle modifications and diet, little prevention can be done towards this maternal complication. Through a preclinical approach and a retrospective clinical trial, we investigated the effects of maternal supplementation with a nutraceutical composition based on resveratrol (RSV) and alpha-lipoic acid (ALA) on insulin resistance and GDM status

COVID-19 pandemic is a global threat, where the rate of infection with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) increases exponentially, and the spread of the virus from person to person is very fast. Fitting models for COVID-19 counts receive a great attention, and modelling the dispersion of COVID-19 counts helps measuring the spread of the disease in a population and evaluating the intervention

The vibrations of carbon nanotubes under the influences of various internal and external forces have been subjects of interests for some years. These researches have not really considered the effects of surface energy and initial stress which are very important from both material and mechanical aspects of views. Therefore, the current study presents the simultaneous impacts of surface energy, initial stress and nonlocality and other various parameters on the nonlinear vibration of carbon nanotube hot fluid-conveying resting on elastic foundations in a magnetic environment. The derived equations governing the behaviours are solved using Galerkin’s decomposition-Adomian decomposition method is adopted to explore the concurrent impacts of surface elasticity, initial stress, residual surface tension and nonlocality on the nonlinear vibration of singlewalled carbon conveying nanotube resting on linear and nonlinear elastic foundation and operating in a thermo-magnetic environment

Supraventricular tachycardia is the most common type of tachyarrhythmia seen in childhood. First-line treatments (adenosine, esmolol-propranolol, digoxin, electrical cardioversion) usually suppress tachycardia, but rarely tachycardia is resistant and requiring Class IC and/or Class III agents, such as amiodarone, sotalol, propafenone, and flecainide.

According to the UNAIDS 2022 report, 52% of the HIV positive children between 0-14 years were able to access treatment and of these 68% attain viral suppression. CCR5 promoter genotype specifically single nucleotide polymorphisms have been linked to modulate patient virological status. However, the few studies that have studied the association in infants have utilized allele-specific PCR a genotypic method limited to detecting already known SNPs. By using Sanger sequencing, we explored the association taking into account novel mutations.

Before the development of highly active antiretroviral medication, AIDS and related illnesses caused a great deal of suffering and death. All of the AIDS-related morbidities and mortality have considerably decreased thanks to modern medication, especially in industrialized nations. However, this accomplishment is still elusive in underdeveloped nations, particularly in those in sub-Saharan Africa. This failure can be attributed to a number of factors. Poverty, ignorance about the treatment, and inadequate therapy adherence are at the top of this list.

Oxidative stress associated with bacterial infections, are recognized as being a key factor in the appearance and complications of many chronic pathologies. To help overcome these difficulties, herbal remedies are one of the alternatives for the development of traditionally improved drugs. The objective of this work is to evaluate the antiradical and antibacterial activities of the ethanolic extract of the bark of the trunk of Terminalia avicennioides. Plant used in traditional medicine in Chad in the treatment of infectious diseases.

Penicillin and streptomycin are the most commonly used to prevent bacterial infection or contamination in cell culture. However, the role of Penicillin-streptomycin on inducing mouse embryonic stem cells(mESCs) to differentiate into cardiomyocytes is unclear. To illustrate the mechanism of penicillin-streptomycin on inducing mESCs differentiation into cardiomyocytes, we firstly investigated mESCs differentiation into cardiomyocytes by the traditional method. The time- space expressions of cardiac-specific genes were detected by real-time PCR and western blotting at 8 different time-points over a period of 36 days. Furthermore, action potentials were measured by patch clamp for mESC-derived cardiomyocytes. Embryonic bodies through hanging drop method, were incubated with penicillin-streptomycin (P/S) at different concentrations (1×PBS, 1×, 2×, 5×), and then, the number of cardiomyocytes and expression levels of myocardial marker proteins were detected by flow cytometry, cellular immunofluorescence, and western blotting, respectively. We found that the SSEA-1 of mESC presented green fluorescence, and H.E. staining showed karyoplasmic ratio >>1. Besides, TNNI3, TNNT2, ACTN2 and MYL-2v were clearly visible by cellular immunofluorescence. Furthermore, the ACTN2 positive cells rate of 2× and 5× groups were remarkably higher than that in Cntl (1×PBS) group and 1× group (10 Units/mL penicillin; 10 μg/mL streptomycin), as well as the expressions of GATA4, MYL-2v, TNNI3, ACTN2

Purpose: We aimed to create mechanic optic nerve injury model in rats and investigate the neuroprotective effects of ripasudil on retinal ganglion cells. Study Design: Experimental study Methods: Mechanic optic nerve injury model was created in the right eyes of male Wistar rats (n=15). Rats were divided into three groups: glaucoma model with sham treatment (group1) and 20 µM intravitreal ripasudil treatment (group 2) and 50 µM intravitreal ripasudil treatment (group 3). Treatment was applied intravitreally and rats were sacrificed at the end of 4 weeks. Glial fibrillary acidic protein (GFAP), Brn-3a antibody,anti- Iba1 was examined by immunohistochemistry. Results: The number of Brn-3a positive RGC in the mechanical optic nerve injury model was 5.33 ± 2.08 (min: 3, max: 7) in sham group, 10.25 ± 2.63 (min: 8, max: 14) in 20 µM group and 16.75 ± 5.43 (min:9, max: 21) in 50 µM group (p <0.05). GFAP positive RGC counts were recorded as 24.33 ± 2.08 (min: 22, max: 26) in sham group, 16.75 ± 1.70 (min: 15, max: 19) in 20 µM group and 13.00 ± 4.08 (min:10 , max: 19) in 50 µM group (p <0.05). Ripasudil treatment also decreased Iba1 expression in the retina of mechanic optic nerve injury groups. In addition, ripasudil treatment prevented apoptotic cell death by increasing Bcl-xL protein expression and preserved Tfam protein expression in the retina. Conclusions: Our experimental study has shown that ripasudil is neuropreotective in mechanical optic nerve injury model.

Low temperature (but above-freezing) during germination and early seedling growth of chilling-sensitive crop is one of the most significant limiting factors in the productivity. 2,4-Epibrassinolide (24-EB) is one of the most active forms of brassinosteroids are multifunctional plant hormones that can regulate development and respond to abiotic stresses. The effect of seed-pretreatment with 24-EB (12.5 μg/L) on photosynthetic characteristics, membrane permeability, lipid peroxidation and antioxidant activities under chilling stress were investigated in tomato (Lycopersicon esculentum Mill.) cultivars: Kulon (early ripening) and Yakhont (mid-early). Results showed that the use of 24-EB led to more pronounced changes in the pigment composition in Yakhont in the absence of a stress factor, whereas in Kulon under chilling stress (2 o C for 24 h). 24-EB pretreatment minimized the damage to cell membranes in tomato plants caused by chilling stress. The tolerance to chilling stress in Yakhont was higher than Kulon (by electrolyte leakage and content of malondialdehyde assay). Under these conditions, oxidative processes in plants of Yakhont did not show significant difference. We have not established the effect of 24-EB on the level of low molecular weight antioxidants in tomato cultivars (measured by inhibition of 2,2-diphenyl-1-picrylhydrazyl free radical method). The antioxidant activity of leaf extracts in Yakhont was twice as high as in Kulon under all experimental conditions (with/without 24-EB, 22/2 o C). It was concluded that the less pronounced reaction of plants of Yakhont to the use of 24-EB and chilling stress is due to their genetically determined higher cold resistance than that of Kulon.
