BACKGROUND Liver fibrosis is the primary cause of liver cirrhosis and hepatocellular carcinoma and leads to considerable morbidity and mortality. Recent studies have shown that microRNAs are associated with fibrotic processes in liver disorders, but the exact role of miR-202 is still unclear, and its related mechanisms are not fully understood. AIMS The aim of this research is to analyze the regarded regulation of miR-202 on HGF and its role in the pathological progress of liver fibrosis. METHODS In the present study, qRT-PCR was used to detect the expression level of miR-202 in serum of patients with liver fibrosis and to compare its expression in patients with different pathological stages. HGF was predicted to be the target gene of miR-202 by TargetScan and was verified by Dual-luciferase reporter gene assay. qRT-PCR and western blot were used to detect the regulatory effect of mir-202 on the mRNA and protein of HGF; effect of miR-202 on the expression of fibrosis factors α-smooth muscle actin (α-SMA), FSPibrosis injury was promoted.The simultaneous expression of AmRosea1 and AmDelila transcription factors from snapdragon can activate the anthocyanin pathway in orange carrots, leading to the synthesis and accumulation of anthocyanins in the taproots. Anthocyanins are phenolic compounds produced in various parts of plants. They are used as natural food dyes and are reported as beneficial antioxidants for humans. Black carrot is an important source for anthocyanins; however, the reason for the lack of anthocyanin production in the orange carrot is unknown. Anthocyanins are synthesized by a specific branch of the phenylpropanoid pathway that has previously been reported to be activated by a triad of R2R3-MYB, basic helix-loop helix (bHLH) and WD40 transcription factors (TFs). In the current study, orange carrots were turned purple by simultaneous expression of R2R3-MYB and bHLH TFs, i.e. AmRosea1 and AmDelila from snapdragon (Antirrhinum majus). Simultaneous transgenic expression of the TFs under a constitutive promoter in the orange carrot cultivar 'Danvers 126' lead to consistent upregulation of anthocyanin-related biosynthetic genes and significant accumulation of anthocyanins in leaves, stems and taproots. Highest overall content of soluble anthocyanins in the taproot among the transformants amounted to 44.38 mg g-1 dry weight. The anthocyanin profile of the transformants were significantly different from the profile in the reference black carrot 'Deep Purple'. The main anthocyanins present in the transformed taproots were cyanidin 3-xylosyl(sinapoylglucosyl)galactoside, whereas the main anthocyanin present in Deep Purple was cyanidin 3-xylosyl(feruloylglucosyl)galactoside. This study confirms the presence of the necessary biosynthetic genes in orange carrots for production of anthocyanins and demonstrates the absence of suitable R2R3-MYB and bHLH TFs for stimulating anthocyanin biosynthesis in the orange carrot.Among the five cassava isoforms (MeAPL1-MeAPL5), MeAPL3 is responsible for determining storage root starch content. Degree of storage root postharvest physiological deterioration (PPD) is directly correlated with starch content. AGPase is heterotetramer composed of two small and two large subunits each coded by small gene families in higher plants. Studies in cassava (Manihotesculenta) identified and characterized five isoforms of ManihotesculentaADP-glucose pyrophosphorylase large subunit (MeAPL1-MeAPL5) and employed virus induced gene silencing (VIGS) to show that MeAPL3 is the key isoform responsible for starch and dry matter accumulation in cassava storage roots. Silencing of MeAPL3 in cassava through stable transgenic lines resulted in plants displaying significant reduction in storage root starch and dry matter content (DMC) and induced a distinct phenotype associated with increased petiole/stem angle, resulting in a droopy leaf phenotype. Plants with reduced starch and DMC also displayed significantly reduced or no postharvest physiological deterioration (PPD) compared to controls and lines with high DMC and starch content. This provides strong evidence for direct relationships between starch/dry matter content and its role in PPD and canopy architecture traits in cassava.INTRODUCTION The intracerebral hemorrhage (ICH) score provides an estimate of 30-day mortality for patients with intracerebral hemorrhage in order to guide research protocols and clinical decision making. Several variations of such scoring systems have attempted to optimize its prognostic value. More recently, minimally invasive surgical techniques are increasingly being used with promising results. this website As more patients become candidates for surgical intervention, there is a need to re-discuss the best methods for predicting outcomes with or without surgical intervention. METHODS We systematically performed a scoping review with a comprehensive literature search by two independent reviewers using the PubMed and Cochrane databases for articles pertaining to the "intracerebral hemorrhage score." Relevant articles were selected for analysis and discussion of potential modifications to account for increasing surgical indications. RESULTS A total of 64 articles were reviewed in depth and identified 37 clinical grading scales for prognostication of spontaneous intracerebral hemorrhage. The original ICH score remains the most widely used and validated. Various authors proposed modifications for improved prognostic accuracy, though no single scale showed consistent superiority. Most recently, scales to account for advances in surgical techniques have been developed but lack external validation. CONCLUSION We provide the most comprehensive review to date of prognostic grading scales for patients with intracerebral hemorrhage. Current prognostic tools for patients with intracerebral hemorrhage remain limited and may overestimate risk of a poor outcome. As minimally invasive surgical techniques are developed, prognostic scales should account for surgical candidacy and outcomes.In the present scenario of drug discovery, several screening filters ensure a rigorous nomination of clinical candidates. One of these screens is the determination of IC50, the concentration of drug at half-maximal inhibitory concentration, also known as a potency assay. However, various nuances pertaining to the design, execution, and interpretation of in vitro potency results suggest a sizeable opportunity for the generation of erroneous data. The focus areas of this article include (1) examining the requirement for the addition of serum albumin in in vitro potency assays, (2) problems encountered with cell lysates, and (3) drug candidate stability concerns during in vitro potency assays/high-throughput screening. Based on this assessment, the interpretation of the data generated using cell-based systems (i.e., lysates with or without the addition of fetal bovine serum) should be carried out with caution for in vitro potency testing, and the inclusion of a correction factor for non-specific protein binding should be considered.
