Objective: Over 50% of the world populations are infected with Helicobacter pylori (H. pylori). Most subjects are asymptomatic; however, in 1994, H. pylori has been categorized as group I carcinogen. The aim of the study was to investigate the relationship between H. pylori infection and gastric cancer.

Refaee, "Distant large acute epidural hematoma after closed cerebrospinal fluid tapping through the anterior fontanelle: A case report and its pathogenesis.", Surgical neurology international, vol. 12, pp. 59, 2021. Abstract

BACKGROUND: Cerebrospinal fluid (CSF) infection is one of the most common and serious complications of shunt placement. The CSF shunt infections are preferably treated with intravenous antibiotics, infected shunt removal, repeated tapping (infants) or placement of an external ventricular drainage (EVD) device, and placement of a new shunt once the CSF is sterile. The tapping through the anterior fontanelle is commonly used instead of the EVD in developing countries to manage CSF infection in open anterior fontanelle patients. To the best of our knowledge, this would be considered the first reported case of distant epidural hematoma after closed ventricular tapping.

CASE DESCRIPTION: We report a case of 6-months child with Chiari malformation (Type II) presenting to us with a shunt infection with possible obstruction. CSF was aspirated for examination through a tap through the anterior fontanelle followed by the development of extradural hemorrhage far from the tapping site.

CONCLUSION: EDH after a transfontanellar ventricular tap can rapidly evolve and lead to patient death. This report raises the awareness of the neurosurgeons to this possible complication that can happen and leads to major complications. Monitoring the conscious level would be needed after ventricular tapping to detect this possible complication.

Building NLP applications from scratch is a difficult task that takes a lot of time and requires acquiring a lot of NLP knowledge. For a rich language like Arabic the difficulties is increased significantly. In this paper, we investigated how to build a tool that helps NLP application developers to build rapid and robust applications. It involves two steps. Firstly, using COM objects technology in building common NLP tools. Secondly, building NLP applications that uses these tools which can access these tools either locally or remotely. We have demonstrated the capabilities of the COM objects in developing NLP tools such as morphological analyzer and used it for building two Arabic NLP applications.

The objective of our study is to highlight the therapeutic effect and mechanism of action by which purified Flaxseed hydrolysate (PFH) which is a lignan rich fraction exerts its anticancer activity on a human breast cancer cell line (T47D) and in mice bearing tumor. HPLC analysis of PFH of six flaxseed cultivars had shown that PFH of the cultivar Giza 9 (PFH-G9) contains the highest concentration of SDG (81.64 mg/g). The in vitro cytotoxic potentiality of PFH's of six flaxseed cultivars was screened against a panel of human cancer cell lines. PFH -G9 showed the most significant cytotoxic activity against ER-receptor positive breast cell lines MCF7 and T47D with IC 13.8 and 15.8 µg/ml, respectively. Moreover, PFH-G9 reduced the expression of the metastasis marker, 1-α, metalloproteinases and vascular endothelial growth factor (VEGF), one of the most potent stimulators of angiogenesis, while it increased the caspase-3 dependent apoptosis. Our study also showed that dietary intake of 10% of Giza 9 Flaxseeds (FS), fixed oil (FSO) or Flax meal (FSM) twice daily for 3 weeks in mice-bearing solid Ehrlich ascites carcinoma (EAC) resulted in reducing the tumor volume, the expression of estrogen, insulin growth factor, progesterone, VEGF and MMP-2, but enhanced expression of caspase-3.
