Background Despite the recognition of food allergies as a significant cause of morbidity and a growing public health burden worldwide, there are no epidemiological studies addressing food sensitization and allergy in Jordan. Objective To conduct an epidemiological study that retrospectively analyzes sensitization data from 3463 patients with suspected immunoglobulin E (IgE)-mediated food allergic reactions who performed specific IgE tests in our laboratories in Jordan. Methods Specific IgE (s-IgE) tests were analyzed for patients who performed enzyme allegro-sorbent testing based on either self-reported food allergy or upon physician's request. Results 2.3% of the analyzed samples were cross-reactive to carbohydrate determinants. A quarter of the patients were sensitized to one or more food allergens, with males having higher odds of being s-IgE positive. Furthermore, a higher prevalence of sensitization was seen in infants and children compared with adults. s-IgE was most frequently found against cow milk (11.2%), pistachio (4.9%), soybean (4.6%), cherry (4.4%), and orange (4.4%). Interestingly, the s-IgE class distribution profile of pistachio differed from the rest of the top hits being skewed away from the weak class 1 leaning more towards higher IgE classes. Food allergen sensitization was age group-dependent milk, tree nuts, and eggs were the main food groups causing sensitization in infants, while it was fruits followed by milk in children and adults. Conclusions Our work represents the first epidemiological study addressing food sensitization in Jordan. This study lays a solid foundation for future studies that can help better guide food allergy diagnosis, patient dietary modifications, and food elimination plans, as well as assist decision-makers in the region to develop national strategies for an efficient and sustainable healthcare system.Objective The endothelial glycocalyx covers the luminal surface of the endothelium and plays key roles in vascular function. Despite its biological importance the ideal visualisation techniques are lacking. The current study aimed to improve the preservation and subsequent imaging quality of the endothelial glycocalyx. Methods In mice, the endothelial glycocalyx was contrasted with a mixture of Lanthanum and Dysprossium (LaDy). Standard chemical fixation was compared with high pressure frozen specimens processed with freeze substitution. Cyclopamine molecular weight Also, isolated brain microvessels and cultured endothelial cells were high pressure frozen and by transmission soft x-ray imaged under cryogenic conditions. Results The endothelial glycocalyx was in some tissues significantly more voluminous from chemically fixed specimens compared with high-pressure frozen specimens. LaDy labelling introduced excessive absorption contrast which impeded glycocalyx measurements in isolated brain microvessels when using transmission soft x-rays. In non-contrasted vessels, the glycocalyx was not resolved. LaDy-contrasted, cultured brain endothelial cells allowed to assess glycocalyx volume in vitro. Conclusions Both chemical and cryogenic fixation followed by dehydration lead to substantial collapse of the glycocalyx. Cryogenic fixation without freeze substitution could be a way forward although transmission soft x-ray tomography based solely on amplitude contrast seems unsuitable.Vision therapy in the form of ocular motor training is increasingly used to treat visual complaints, particularly in the setting of persistent symptoms after mild traumatic brain injury (mTBI). In this review, we discuss the rationale behind this intervention and the evidence for its utility. Although the efficacy of exercises for primary convergence insufficiency is plausible and supported by data, there is not yet strong evidence of benefit for the post-traumatic variant. It is not established that abnormalities in fixation, pursuit, and saccades in mTBI are the cause of post-concussive symptoms, or that these abnormalities arise from ocular motor damage rather than being secondary effects of cognitive problems with attention or executive control. The few studies to date have significant methodological weaknesses. More substantial evidence is required before vision therapy can be accepted as a useful tool in the rehabilitation of patients with brain trauma.

This study assessed whether a short course of exercise training post-AECOPD with periodic reinforcement exercise training and phone call reminders reduces readmissions and increases physical activity in COPD patients. Methods Subjects were randomized into either the (i) intervention group (IG), consisting of 4-8 weeks of training supervised by a physiotherapist and phone contact every 2 weeks by a case manager providing support and reinforcement of continuous exercise at home or (ii) usual care group (UG), which had no input by a physiotherapist or case manager. Readmissions were assessed at 12 months. Activities of all patients were assessed by an activity monitor at baseline, 3 and 12 months. Results Altogether, 136 subjects were included and randomized (68 in IG and 68 in UG). The age, gender and FEV1 % predicted were 75.0 ± 6.7 years, 132 males and 47.0 ± 16.2%, respectively. The mean number of readmissions for AECOPD (1.06 vs 1.72 times, P = 0.014) was less and time to first readmission was increased (146.8 vs 122.4 days, P = 0.005) in the IG versus UG at 12 months. At 12 months, there was no change in activity measured by activity monitor between the two groups. Conclusion This programme decreased exacerbation frequency and increased the time of readmissions for AECOPD. It did not improve physical activities and exercise tolerance at 12 months.Microtextures of titanite (CaTiSiO5 ) in exceptionally preserved Archean pillow lavas have been proposed as the earliest examples of microbial ichnofossils. An origin from microbial tunneling of seafloor volcanic glass that is subsequently chloritized and the tunnels infilled by titanite has been argued to record the activities of subseafloor microbes. We investigate the evidence in pillow lavas of the 3.35 Ga Euro Basalt from the Pilbara Craton, Western Australia, to evaluate the biogenicity of the microtextures. We employ a combination of light microscopy and chlorite mineral chemical analysis by EPMA (electron probe micro-analysis) to document the environment of formation and analyze their ultrastructure using FIB-TEM (focussed ion beam combined with transmission electron microscopy) to investigate their mode of growth. Petrographic study of the original and re-collected material identified an expanded range of titanite morphotypes along with early anatase growth forming chains and aggregates of coalesced crystallites in a sub-greenschist facies assemblage.
