A Case Report Of A Giant Plunging Ranula In A 25-Year-Old Patient: A case report

Abstract This case report aims to present an unusual case of a plunging ranula that extended to the superior vertebral body of the T4 vertebrae, we will be elaborating on the patient presentation, investigations, diagnosis, and treatment of the lesion, while also talking about the adversities faced while diagnosing and treating the patient. The rarity of this condition and an atypical presentation makes this a difficult case to diagnose and vigilant treatment is needed to prevent any complications associated with the condition and ensure a successful treatment and recovery

Effect of early tranexamic acid administration on mortality, hysterectomy, and other morbidities in women with post-partum haemorrhage (WOMAN): an international, randomised, double-blind, placebo-controlled trial

Background Post-partum haemorrhage is the leading cause of maternal death worldwide. Early administration of tranexamic acid reduces deaths due to bleeding in trauma patients. We aimed to assess the effects of early administration of tranexamic acid on death, hysterectomy, and other relevant outcomes in women with post-partum haemorrhage. Methods In this randomised, double-blind, placebo-controlled trial, we recruited women aged 16 years and older with a clinical diagnosis of post-partum haemorrhage after a vaginal birth or caesarean section from 193 hospitals in 21 countries. We randomly assigned women to receive either 1 g intravenous tranexamic acid or matching placebo in addition to usual care. If bleeding continued after 30 min, or stopped and restarted within 24 h of the first dose, a second dose of 1 g of tranexamic acid or placebo could be given. Patients were assigned by selection of a numbered treatment pack from a box containing eight numbered packs that were identical apart from the pack number. Participants, care givers, and those assessing outcomes were masked to allocation. We originally planned to enrol 15 000 women with a composite primary endpoint of death from all-causes or hysterectomy within 42 days of giving birth. However, during the trial it became apparent that the decision to conduct a hysterectomy was often made at the same time as randomisation. Although tranexamic acid could influence the risk of death in these cases, it could not affect the risk of hysterectomy. We therefore increased the sample size from 15 000 to 20 000 women in order to estimate the effect of tranexamic acid on the risk of death from post-partum haemorrhage. All analyses were done on an intention-to-treat basis. This trial is registered with ISRCTN76912190 (Dec 8, 2008); ClinicalTrials.gov, number NCT00872469; and PACTR201007000192283. Findings Between March, 2010, and April, 2016, 20 060 women were enrolled and randomly assigned to receive tranexamic acid (n=10 051) or placebo (n=10 009), of whom 10 036 and 9985, respectively, were included in the analysis. Death due to bleeding was significantly reduced in women given tranexamic acid (155 [1·5%] of 10 036 patients vs 191 [1·9%] of 9985 in the placebo group, risk ratio [RR] 0·81, 95% CI 0·65–1·00; p=0·045), especially in women given treatment within 3 h of giving birth (89 [1·2%] in the tranexamic acid group vs 127 [1·7%] in the placebo group, RR 0·69, 95% CI 0·52–0·91; p=0·008). All other causes of death did not differ significantly by group. Hysterectomy was not reduced with tranexamic acid (358 [3·6%] patients in the tranexamic acid group vs 351 [3·5%] in the placebo group, RR 1·02, 95% CI 0·88–1·07; p=0·84). The composite primary endpoint of death from all causes or hysterectomy was not reduced with tranexamic acid (534 [5·3%] deaths or hysterectomies in the tranexamic acid group vs 546 [5·5%] in the placebo group, RR 0·97, 95% CI 0·87-1·09; p=0·65). Adverse events (including thromboembolic events) did not differ significantly in the tranexamic acid versus placebo group. Interpretation Tranexamic acid reduces death due to bleeding in women with post-partum haemorrhage with no adverse effects. When used as a treatment for postpartum haemorrhage, tranexamic acid should be given as soon as possible after bleeding onset.

SEMANTIC DEROGATION IN ANIMAL METAPHORS: A CASE STUDY OF AESOP’S FABLES

Stories play a significant role in schema development as they can shape the reader’s view. Children's fiction stories, in particular, have a significant impact on readers' inner schemas. This research has been carried out using a mixed-methods approach. This research has four objectives. Firstly, to explore Aesop’s fables for animal metaphors Secondly, to highlight the use of semantic derogation in Aesop’s fables Thirdly, to compare the readers' perceptions of the animal metaphors used in Aesop’s fables. The samples have been taken from private schools, specifically from students at the primary level. How far does the animals' representation in Aesop’s fables impact the reader’s schema? The majority of literature readers have an impact on their schemas of animal representation in Aesop's fables, according to this study. It is possible that media and animated cartoons in which animal characteristics have been used still carry the derogatory perception of the animals as depicted in fables. However, in the other cases where the learner's perception of these animals differs from the fables, Aesop has no influence. There are some other influences such as cultural influence, media, animated cartoons, social media, domestic reasons, and other environmental factors involved

Lp16-PSP, a Member of YjgF/YER057c/UK114 Protein Family Induces Apoptosis and p21WAF1/CIP1 Mediated G1 Cell Cycle Arrest in Human Acute Promyelocytic Leukemia (APL) HL-60 Cells

Lp16-PSP (Latcripin 16-Perchloric acid Soluble Protein) from Lentinula edodes strain C91-3 has been reported previously in our laboratory to have selective cytotoxic activity against a panel of human cell lines. Herein, we have used several parameters in order to characterize the Lp16-PSP-induced cell death using human acute promyeloid leukemia (HL-60) as a model cancer. The results of phase contrast microscopy, nuclear examination, DNA fragmentation detection and flow cytometry revealed that high doses of Lp16-PSP resulted in the induction of apoptosis in HL-60 cells. The colorimetric assay showed the activation of caspase-8, -9, and -3 cascade highlighting the involvement of Fas/FasL-related pathway. Whereas, Western blot revealed the cleavage of caspase-3, increased expression of Bax, the release of cytochrome c and decreased expression of Bcl-2 in a dose-dependent manner, suggesting the intrinsic pathway might be involved in Lp16-PSP-induced apoptosis as well. Low doses of Lp16-PSP resulted in the anchorage-independent growth inhibition, induction of G1 phase arrest, accompanied by the increased expression of p21WAF1/CIP1, along with the decreased expression of cyclin D, E, and cdk6. In addition, Lp16-PSP resulted in constitutive translocation inhibition of transcription factor nuclear factor kappa B (NF-κB) into the nucleus by decreasing the phosphorylation of IκBα. All these findings suggested Lp16-PSP as a potential agent against acute promyeloid leukemia; however, further investigations are ultimately needed

LP1 from Lentinula edodes C91-3 Induces Autophagy, Apoptosis and Reduces Metastasis in Human Gastric Cancer Cell Line SGC-7901

Present study aimed to elucidate the anticancer effect and the possible molecular mechanism underlying the action of Latcripin 1 (LP1), from the mushroom Lentinula edodes strain C91-3 against gastric cancer cell lines SGC-7901 and BGC-823. Cell viability was measured by Cell Counting Kit-8 (CCK-8); morphological changes were observed by phase contrast microscope; autophagy was determined by transmission electron microscope and fluorescence microscope. Apoptosis and cell cycle were assessed by flow cytometer; wound-healing, transwell migration and invasion assays were performed to investigate the effect of LP1 on gastric cancer cell’s migration and invasion. Herein, we found that LP1 resulted in the induction of autophagy by the formation of autophagosomes and conversion of light chain 3 (LC3I into LC3II. LP1 up-regulated the expression level of autophagy-related gene (Atg7, Atg5, Atg12, Atg14) and Beclin1; increased and decreased the expression level of pro-apoptotic (Bax) and anti-apoptotic (Bcl-2) proteins respectively, along with the activation of Caspase-3. At lower-doses, LP1 have shown to arrest cells in the S phase of the cell cycle and decreased the expression level of matrix metalloproteinase MMP-2 and MMP-9. In addition, it has also been shown to regulate the phosphorylation of one of the most hampered gastric cancer pathway, that is, protein kinase B/mammalian target of rapamycin (Akt/mTOR) channel and resulted in cell death. These findings suggested LP1 as a potential natural anti-cancer agent, for exploring the gastric cancer therapies and as a contender for further in vitro and in vivo investigations
