Reactive gliosis and inflammation are risk factors for white matter injury (WMI) development, which are correlated with the development of many neurodevelopmental deficits with no treatment. This study aimed to understand the mechanisms correlated with WMI, with a particular focus on the role of nuclear factor‑kappa B (NF‑kB) and p38 mitogen‑activated protein kinases (MAPKs) pathways. Seven‑day‑old Wistar rats were used to generate cerebellar tissue slices. Slices were cultured and randomly allocated to one of 3 groups and treated as follows: group‑I (control); group‑II (WMI), slices were subjected to 20 min of oxygen‑glucose deprivation (OGD); group‑III (WMI+ blockers), slices were subjected to OGD and treated with the blockers. Results showed that OGD insult triggered a marked increase in the apoptosis among WM elements, as confirmed by TUNEL assay. Immunocytochemical experiments revealed that there was a significant decrease in the percent of MBP+ OLs and NG2+ OPCs, and myelin integrity. There was also a significant increase in the percent of reactive microglia and astrocytes. BrdU immunostaining revealed there was an increase in the percent of proliferating microglia and astrocytes. Q‑RT‑PCR results showed OGD upregulated the expression levels of cytokines (TNF‑α, IL‑1, IL‑6, and IL‑1β) and inducible nitric oxide synthase (iNOS). On the other hand, treatment with BAY11 or SB203580 significantly enhanced the OL survival, restored myelin loss, and reduced microglia and astrocyte reactivity, and downregulated the iNOS and cytokine expression. Our findings demonstrate that blocking of NF‑KB/p38 MAPK pathways alleviated reactive gliosis, inflammation, and OL loss upon WMI. The findings may help to develop therapeutic interventions for WMI.

The extra demand imposed upon the Libyan health services during and after the Libyan revolution in 2011 led the ailing health systems to collapse. To start the planning process to re-engineer the health sector, the Libyan Ministry of Health in collaboration with the World Health Organisation (WHO) and other international experts in the field sponsored the National Health Systems Conference in Tripoli, Libya, between the 26th and the 30th of August 2012. The aim of this conference was to study how health systems function at the international arena and to facilitate a consultative process between 500 Libyan health experts in order to identify the problems within the Libyan health system and propose potential solutions. The scientific programme adopted the WHO health care system framework and used its six system building blocks: i) Health Governance; ii) Health Care Finance; iii) Health Service Delivery; iv) Human Resources for Health; v) Pharmaceuticals and Health Technology; and vi) Health Information System. The experts used a structured approach starting with clarifying the concepts, evaluating the current status of that health system block in Libya, thereby identifying the strengths, weaknesses, and major deficiencies. This article summarises the 500 health expert recommendations that seized the opportunity to map a modern health systems to take the Libyan health sector into the 21st century arabic 10 English 65

Despite the relative abundance of sunny weather, surprisingly, there is increasing evidence that vitamin D deficiency is extremely prevalent in females of reproductive age in Middle East countries. There is also increasing interest in the non-classical roles of vitamin in health and disease including its relation to incidence of gestational diabetes, its impact on glycaemic control in diabetes mellitus, and its association with some complications of pregnancy like preeclampsia. The objective of this study was to estimate the prevalence of Vitamin D deficiency in pregnant diabetic patients in west Libya and analyse potential links to socioeconomic and cultural factors. This is a cross sectional observational study. Random plasma was collected form expected mothers attending the Antenatal Diabetes Clinic at Tripoli’s Main Maternity Hospital. Demographics and socioeconomic and cultural factors were recorded at the same time. Samples were analysed for vitamin D level and biochemical screening panel. Vitamin D level was obtained from 160 patients (mean age 35 years). Over all 95 % of the study population had vitamin D levels below normal (defined as vitamin D level of < 20 ng/mL). Results were subcategorised into severe deficiency ( 30 ng/ml, only 1.3%, 2 patients). All patients were taking daily vitamin D Supplements at a dose of 400 IU as per hospital policy. Vitamin D deficiency is extremely prevalent in pregnant diabetic patients in Libya. There is no clear association with socioeconomic risk factors like employment, type of accommodation or geographic distribution. However, most of the study population had life style characterized by minimal exposure to direct sun arabic 11 English 70
