Cytoglobin (Cygb) is an oxygen transporter marker that appears in hypoxic conditions. The clinical condition of Corona Virus Disease 2019 (COVID-19) cases, in general is that patients experience hypoxemia with low oxygen saturation. The Cygb gene is stimulated by the Hypoxia-Inducible Factor-1alpha (HIF-1α) transcription factor, which is stable in hypoxia. This study investigates Cygb expression in hypoxic COVID-19 cases. The design of this research is analytically observational. Parameters measured were Cygb mRNA and protein levels, correlation of HIF-1α and Cygb proteins in COVID-19 patients with Alpha, Beta, Delta, Omicron variants and negative control patients. The results showed that each Cygb mRNA level decreased by 0.50, 0.92, 0.75 and 0.84 times that of the control. In contrast, Cygb protein levels (ng/mL) increased (16.95; 20.33; 21.20; 14.01 and 6.29 control). Strong negative correlation between mRNA and Cygb protein (R = -0.611). Strong positive correlation between HIF-1α and Cygb protein (R = 0.670). This study showed that Cygb mRNA expression decreased, further increasing Cygb protein; HIF-1α protein levels increased, further increasing Cygb protein. In COVID-19 patients (Alpha, Beta, Delta and Omicron variants), there is an increase in Cygb protein levels through stimulation of HIF-1α, which is stable under hypoxic conditions. The regulation of Cygb in this study has the potential to become the basis for handling cases of viral infections or other cases of hypoxia.

Recently more attention has been paid to identifying biomarkers for epilepsy to direct a more personalized treatment strategy, especially for patients who suffer from drug-resistant epilepsy which carries a much poorer prognosis. microRNA has emerged as an important and diverse type of biomarker that can participate in metabolic and cellular processes of the disease and, importantly, be detected in patient’s serum. In this short review, we compile state-of-the-art evidence regarding miRNA-146a, a novel biomarker that shows high potential for studying epileptogenesis, monitoring disease progression, evaluating treatment response, and may even functioning as a therapeutic target given its role in the process of neuroinflammation.

It aims to compare the levels of p53 in maternal and umbilical cord venous samples of healthy pregnant and preeclamptics. Preeclampsia is a leading cause of both maternal morbidity and neonatal mortality. The etiology and pathogenesis of preeclampsia are not yet fully understood. Apoptosis during pregnancy develops due to multiple different mechanisms. No studies are available in the literature documenting any association between fetal sex and p53 levels; also, the status of p53 in cord blood is unclear. Hence the study was designed to compare p53 levels in maternal and umbilical cord venous samples to study both maternal and fetal aspects of preeclampsia. The present study was conducted in 30 normotensive, primigravida women and 30 primigravida preeclamptics (age and gestation matched) with a singleton pregnancy. Serum p53 analysis was carried out in maternal serum and cord blood by solid phase sandwich enzyme-linked immunosorbent assay (Elisa kit). In the present study, maternal and cord p53 levels in preeclamptics were higher. The cord blood p53 levels were significantly higher in preeclamptic mothers with female babies than in preeclamptic mothers with male babies. These findings indicate a definitive role of apoptosis in the pathogenesis of preeclampsia and may be useful in diagnosing patients with preeclampsia and identifying future natal, perinatal and maternal risks. Demonstrating these gender-based changes in p53 levels suggests an active contribution of the placenta in metabolism during pregnancy.

The carbon family nanoparticles are less reviewed for their impact on organisms associated with oxidative stress physiology. This review was carried out after collecting literature on the above topic from various sources, including PubMed and Google Scholar. The carbon family nanoparticles have tissue-specific impacts on various organisms, which are evident at the molecular level. The carbon nanoparticles and molecules of its family need to be very judiciously released as waste to the environment as they may impart toxic effects on organisms.

The decision to treat chronic hepatitis B Virus infection (CHB) may necessitate an assessment of the degree of liver fibrosis. Guidelines recommend Fibroscan examination in such cases. However, it is costly and not widely available. Red cell distribution width (RDW) and platelet count are simple parameters obtained from the blood pictures; and their ratio RDW to platelet ratio (RPR) was claimed to correlate with liver fibrosis. We aimed to assess the ability of RPR to replace the costly fibroscan in the detection of significant fibrosis in chronic hepatitis B patients. This cross-sectional study was conducted in the Tropical medicine department, Tanta University, Egypt, between December 2018 and September 2019. One hundred and twenty-five patients with CHB were included and divided according to the fibroscan examination into: Group I: patients with no significant fibrosis (n=66), Group II: patients with significant (≥ F2) fibrosis (n=59). RPR was calculated for all patients and tested against Fibroscan results. Both groups were matched in regards to age, sex, viral load, and steatosis. There was a significant positive correlation between the degree of stiffness measured by FibroScan in patients with a significant degree of fibrosis and serum bilirubin, a quantitative polymerase chain reaction of hepatitis B virus DNA (HBV DNA PCR), and fibrosis-4 score (FIB-4 score) (P value= 0.020, 0.049, and 0.0402, respectively). However, RPR was not correlated to the degree of fibrosis in fibroscan examination. The accuracy of RDW to platelet ratio (RPR) for the detection of fibrosis in CHB patients is questionable. FIB-4 is correlated with liver stiffness measurement (LSM) in patients with significant fibrosis (F2 or more). Neither RPR, AST to Platelet Ratio Index (APRI) or FIB4 can replace fibroscan for grading of fibrosis in CHB patients for evaluation to start therapy.
决定治疗慢性乙型肝炎病毒感染（CHB）可能需要评估肝纤维化的程度。指南建议在这种情况下进行纤维扫描检查。然而，它成本高昂，而且没有广泛使用。红细胞分布宽度（RDW）和血小板计数是从血液图片中获得的简单参数；并且它们的RDW与血小板比率（RPR）被认为与肝纤维化相关。我们的目的是评估RPR取代昂贵的纤维扫描检测慢性乙型肝炎患者显著纤维化的能力。这项横断面研究于2018年12月至2019年9月在埃及坦塔大学热带医学系进行。125例慢性乙型肝炎患者被纳入，并根据纤维扫描检查分为：第一组：无明显纤维化的患者（n=66），第二组：有明显（≥F2）纤维化的病人（n=59）。计算所有患者的RPR，并对照Fibroscan结果进行测试。两组在年龄、性别、病毒载量和脂肪变性方面匹配。在具有显著纤维化程度的患者中，通过FibroScan测量的硬度与血清胆红素、乙型肝炎病毒DNA的定量聚合酶链式反应（HBV DNA PCR）和纤维化-4评分（FIB-4评分）之间存在显著的正相关（P值分别为0.020、0.049和0.0402）。然而，在纤维扫描检查中，RPR与纤维化程度无关。RDW与血小板比值（RPR）检测慢性乙型肝炎患者纤维化的准确性值得怀疑。FIB-4与具有显著纤维化（F2或以上）的患者的肝硬度测量（LSM）相关。RPR、AST与血小板比值指数（APRI）或FIB4都不能取代纤维扫描来对慢性乙型肝炎患者的纤维化进行分级，以评估开始治疗。

Acne vulgaris (AV), common dermatopathology, has a complex etiopathogenesis with a genetic background. The Survivin gene, which encodes an inhibitor of apoptosis protein, has been linked to some dermatologic disorders. The relationship between Survivin gene polymorphisms and AV has not yet been explored. To study the effect of survivin gene polymorphism rs9904341 and survivin serum concentration on the development of AV in Egyptian patients. Serum survivin was estimated using an enzyme-linked immunosorbent assay. Real-time quantitative PCR using allelic discrimination probes was conducted to investigate the rs9904341 polymorphism in the survivin gene in 118 AV patients and 120 healthy controls. The serum survivin levels were significantly higher in AV patients than controls. Also, it was positively correlated with acne severity. The C allele was significantly more observed in acne patients compared to healthy controls. Patients with the C allele had 1.6 times higher odds of exhibiting acne than those with the G allele. The C/C genotype was significantly more observed in cases versus controls. Patients with the C/C genotype had 2.8 times higher odds of exhibiting acne as compared to those with the G/G genotype. However, no significant association was found between genotype distribution and grades of acne severity. Results showed significant associations between survivin gene rs9904341 genotypes and AV susceptibility, although it was not related to acne severity and could not be used as a marker of disease activity. AV: Acne vulgaris, GAGS: Global Acne Rating System, SNPs: Single nucleotide polymorphisms.

Bleeding gastroesophageal varices are a cause of high mortality among cirrhotic patients. We aimed to investigate late mortality predictors and prognostic models using easily verified factors at admission in cirrhotic patients with acute variceal bleeding (AVB). Between January 2020 and June 2020, 142 patients with AVB from Tanta university hospital were included. Investigating multiple prognostic models was done using multiple logistic regression after identifying significant predictors of 6 months' mortality. Mortality prediction accuracy was assessed with area under the receiver operating characteristic (AUROC) curve. The 6 months’ overall mortality rate was 31% (44 patients had died). AIMS56, Child-Turcotte-Pugh (CTP) grade C and MELD scores were significantly higher among non survivors (p<0.001) while Platelet-albumin-bilirubin (PALBI) was significantly more negative among survivors (P=0.001). Hepatocellular carcinoma was not significantly related to the mortality (p =0.364). Univariate analysis showed that high CTP, MELD, AIMS65 and PALBI scores were predictors of mortality and associated with decreased survival with high sensitivity and low specificity; while multivariate analysis showed that only AIMS56 was independently associated with mortality (p 0.004). CTP, MELD, AIMS65 and PALBI scores are simple, bed side risk scores that can be used for the prediction of 6 months’ mortality after AVB in cirrhotic patients with high sensitivities and lower specificities.

The aim of the study was to evaluate serum c-reactive protein (CRP), ascitic procalcitonin (PCT) and monocyte chemotactic protein-1 (MCP-1) in the diagnosis of spontaneous bacterial peritonitis (SBP) in cirrhotic patients. A cross-sectional analytic study that included 199 patients with decompensated cirrhosis (101 with SBP and 98 without SBP). Patients were classified according to Child-Pugh criteria. Ascitic PCT and MCP-1 were measured by enzyme-linked immunosorbent assay. Serum CRP, liver and renal functions were assessed. Three markers are significantly elevated in SBP patients than those without ascites. Using the ROC curve at AUC 0.883 and a cut-off value of >186 ng/ml, the diagnostic performance of ascitic MCP-1 level was higher than CRP (AUC 0.562) and ascitic fluid procalcitonin (AUC 0.751) in the diagnosis of SBP. The sensitivity and specificity were 86.15% and 79.59% at the cutoff of 186 ng/ml for MCP-1, 65.4 and 75.5 at ≥ 1 ng/ml for PCT, and 52.5 and 64.3, respectively for at 11.2 mg/dl CRP. Ascitic MCP-1 has a better diagnostic value with higher sensitivity and specificity in diagnosis SBP compared to CRP and procalcitonin which has higher diagnostic accuracy than CRP. Further studies with a large number will be necessary to evaluate the usefulness of these markers in diagnosis, follow-up and relation to morbidity and mortality of SBP patients.

Screening of Esophageal Varices (EV) in liver cirrhosis is highly recommended in all consensus reports. The standard screening procedure is endoscopy. Insulin resistance (IR) and the quantitative insulin sensitivity check index (QUICKI) are reliable predictors of portal hypertension. The study aimed to assess and compare the validity of insulin sensitivity/insulin resistance markers and other non-invasive markers for the detection of EVs in post chronic hepatitis C virus cirrhotic patients. In this cross-sectional study, 76 patients were screened by esophagogastroduodenoscopy and abdominal ultrasonography. Estimation of fasting serum insulin by ELISA technique was carried out. Homeostasis model assessment of insulin resistance (HOMA-IR) and QUICKI was performed. The patients with an advanced grade of EV had higher insulin resistance and lower QUICKI. A cut-off value of HOMA-IR ≥ 3.4 could significantly predict EVs with 72% sensitivity and 80.0% specificity. Spleen diameter and platelet count/spleen diameter ratio (PC/SD) showed a significant difference among groups. Lower insulin sensitivity (assessed by QUICKI) and higher insulin resistance (assessed by HOMA IR) were good non-invasive predictors of EVs. In addition, portal vein (PV) diameter, spleen diameter, and PC/SD were also found as predictors of EVs.
