Objective: Decisions to treat large-vessel occlusion with endovascular therapy (EVT) or intravenous alteplase depend on how physicians weigh benefits against risks when considering patients' comorbidities. We explored EVT/alteplase decision-making by stroke experts in the setting of comorbidity/disability.
Methods: In an international multi-disciplinary survey, experts chose treatment approaches under current resources and under assumed ideal conditions for 10 of 22 randomly assigned case scenarios.
Background: Some patients with ischemic stroke have poor outcomes despite small infarcts after endovascular thrombectomy, while others with large infarcts sometimes fare better.
Aims: We explored factors associated with such discrepancies between post-treatment infarct volume (PIV) and functional outcome.
Methods: We identified patients with small PIV (volume ≤ 25th percentile) and large PIV (volume ≥ 75th percentile) on 24-48-h CT/MRI in the ESCAPE randomized-controlled trial.
The glomerulus functions as the filtration unit of the kidney. The mesangial, endothelial, and podocyte cells of the glomerulus exhibit the three clinically most important cell types, which are involved in diverse pathologic processes. Cell death has hardly been investigated in these cells but may be of critical importance to the pathogenesis of nephrotic syndrome, nephritic syndrome, focal segmental glomerulosclerosis (FSGS), mesangial proliferation, and thrombonic microangiopathy (which involves dysfunction and death of glomerular endothelial cells).

The unique vasculature that does not contain collateral vessels favors the kidney over other organs for the investigation of ischemia-reperfusion injury. Unilateral uretic obstruction has become the most prominently studied model for fibrosis with impact far beyond postrenal kidney injury.

Renin Lineage Cells (RLCs) serve as a progenitor cell niche after glomerular damage in the adult kidney. However, it is not clear whether RLCs also contribute to endothelial replenishment in the glomerulus following endothelial injury.

They are usually benign, requiring surgical resection as the treatment of choice. CASE REPORT We present a case of a 59-year-old man with a benign left carotid body tumor that progressed to a very large size, compromised the patient's airway, completely encased the carotid vessels, vagus and hypoglossal nerves ipsilaterally, and reached the contralateral carotid vessels and ipsilateral skull base.

To investigate this possibility, we generated mice with inducible knockout of Gs in JG cells and monitored them for 6 months after induction at 6 weeks of age. The knockout mapped exclusively to the JG cells of the Gs-deficient animals.

The maintenance mechanisms of the RLC pool are still poorly understood. Since RLCs were also identified as a progenitor cell population in bone marrow we first considered that these may be their source in the kidney.

Having verified that the peptides apidaecin 1b and Api88-a designer peptide based on the native apidaecin 1b sequence-are highly active against Gram-negative bacteria, we studied their ability to modulate biological activities of human monocytes and mast cells (MC), two important cell types of the human innate immune system. We could show that both peptides are nontoxic and fairly resistant to degradation in cell culture medium containing 10% FBS.

Abstract. The species identification of Enterocytozoon bieneusi and Encephalitozoon intestinalis is only possible using transmission electron microscopy (TEM), mo lecular techniques and immunofluorescence antibody assays (IFA). In this study, 50 positive and 50 negative fecal specimens for microsporidial spores using the Weber modified trichrome (WMT) staining technique were examined using IFA-MAbs.

Stool samples were collected from 321 individuals aged between 2 and 76 years old, of whom 160 were males and 161 were females. Faecal samples were processed with trichrome staining technique for the primary identification of G.

A cross-sectional study was carried out to determine the current prevalence of protein-energy malnutrition (PEM) among Orang Asli schoolchildren and to investigate the potential predictors of malnutrition. A total of 241 (120 males and 121 females) Orang Asli schoolchildren age 7-12 years living in remote areas of Pos Betau, Pahang participated voluntarily in this study. Anthropometric and socioeconomic data were collected and the children were screened for intestinal parasitic infections.

Haemoglobin (Hb) level was measured and serum iron status was assessed by serum ferritin (SF), serum iron (SI) and total iron binding capacity measurements. Socioeconomic data were collected using pre-tested questionnaires.

Despite great development in socioeconomic status throughout 50 years of independence, Malaysia is still plagued with soil-transmitted helminthiases (STH). STH continue to have a significant impact on public health particularly in rural communities. In order to determine the prevalence of STH among rural Orang Asli children and to investigate the possible risk factors affecting the pattern of this prevalence, fecal samples were collected from 292 Orang Asli primary schoolchildren (145 males and 147 females) age 7-12 years, from Pos Betau, Kuala Lipis, Pahang.
