INTRODUCTION: For sample collection, four sites were selected, sites where fresh water were present, that is, Ravi syphon, BRB Lahore, Shahdara, and Head Baloki. The latitude and altitude of the locations were recorded at the time of collection. RESULTS: A total of 21 species of algae belonging to eight genera and four families were examined in the current studies. The collected samples were mainly filamentous and they were primarily green in color as the photosynthetic pigment found to be dominated was Chlorophyll...

BACKGROUND: Calcifications are an important element of atherosclerotic plaques and have been used as a marker of atherosclerosis and clinical outcome predictor in different vascular territories. CT-scan, performed in the acute ischemic stroke setting, can reliably detect intracranial arterial calcifications. OBJECTIVES: To investigate the association between intracranial internal carotid artery calcification and functional outcome, symptomatic intracerebral hemorrhage (sICH), recanalization, and death...

Generated by Quaking (QKI), circular RNAs (circRNAs) are newly recognised non-coding RNA (ncRNA) members characterised by tissue specificity, increased stability and enrichment within exosomes. Studies have shown that ionizing radiation (IR) can influence ncRNA transcription. However, it is unknown whether circRNAs or indeed QKI are regulated by IR. Microarray circRNA profiling and next generation sequencing revealed that circRNA expression was altered by low and medium dose exposure sourced predominantly from genes influencing the p53 pathway...

An outbreak of extended-spectrum β-lactamase-producing Enterobacter cloacae (ESBL-ECL) occurred in our intensive care unit (ICU) and involved 18 patients (8 infected and 10 colonized). The mean age of patients was 69 years, and all infected patients had underlying medical conditions. Within hours' recognition of the spread of ESBL-ECL, the infection control team requested for staff education, reinforcement of infection control measures, and environmental screening. New transmissions were observed in the institution after weeks of enhanced infection control measures...

BACKGROUND: Non-coaxial rotation has wide applications in engineering devices, e.g. in food processing such as mixer machines and stirrers with a two-axis kneader, in cooling turbine blades, jet engines, pumps and vacuum cleaners, in designing thermal syphon tubes, and in geophysical flows. Therefore, this study aims to investigate unsteady free convection flow of viscous fluid due to non-coaxial rotation and fluid at infinity over an oscillating vertical plate with constant wall temperature...

Leukocyte reduction of donated blood products substantially reduces the risk of a number of transfusion-related complications. Current 'leukoreduction' filters operate by trapping leukocytes within specialized filtration material, while allowing desired blood components to pass through. However, the continuous release of inflammatory cytokines from the retained leukocytes, as well as the potential for platelet activation and clogging, are significant drawbacks of conventional 'dead end' filtration. To address these limitations, here we demonstrate our newly-developed 'controlled incremental filtration' (CIF) approach to perform high-throughput microfluidic removal of leukocytes from platelet-rich plasma (PRP) in a continuous flow regime...

The marked (18)F-flurodeoxyglucose uptake by brown adipose tissue (BAT) enabled its identification in human positron emission tomography imaging studies. In this Perspective, we discuss how glucose extraction by BAT and beige adipose tissue (BeAT) sufficiently impacts on glycemic control. We then present a unique overview of the central circuits modulated by gluco-regulatory hormones, temperature, and glucose itself, which converge on sympathetic preganglionic neurons and whose activation syphon circulating glucose into BAT/BeAT...

An inexpensive, robust and easy to use portable capillary electrophoresis instrument with miniaturized high-voltage capacitively coupled contactless conductivity detection was developed. The system utilizes pneumatic operation to manipulate the solutions for all flushing steps. The different operations, i.e. capillary flushing, interface rinsing, and electrophoretic separation, are easily activated by turning an electronic switch. To allow the analysis of samples with limited available volume, and to render the construction less complicated compared to a computer-controlled counterpart, sample injection is carried out hydrodynamically directly from the sample vial into the capillary by manual syphoning...

BACKGROUND: The methods of arrangement of combined intravenous parallel infusions using anti-reflux valve (ARV), with and without anti-syphon valve (ASV) that could decrease occlusion alarm delay were investigated. METHODS: Occlusion challenge tests were mainly performed as bench experiments of four kinds of multiple parallel infusions (10 ml/h and 50 ml/h infusions), which were connected at the proximal or distal portion of ARV, with or without ASV. Alarm threshold was set to 1000 mmHg...

We present the results of a combined experimental and theoretical investigation of the dynamics of drinking in ruby-throated hummingbirds. In vivo observations reveal elastocapillary deformation of the hummingbird's tongue and capillary suction along its length. By developing a theoretical model for the hummingbird's drinking process, we investigate how the elastocapillarity affects the energy intake rate of the bird and how its open tongue geometry reduces resistance to nectar uptake. We note that the tongue flexibility is beneficial for accessing, transporting and unloading the nectar...

PURPOSE: To elucidate the question whether expansion of pituitary adenomas into the cavernous sinus (CS) has to be regarded as focal penetration rather than invasion, a microanatomical study of the medial wall (MW) of the CS was performed. METHOD: Fourteen sellar hemiblocks underwent microsurgical dissection from lateral and medial approach. The thickness of the MW of the CS was examined by diaphanoscopy. FINDINGS: The internal carotid artery (ICA) was adherent to the MW in five cases...

INTRODUCTION: Reflux in the GSV due to sapheno-popliteal incompetence associated with ascending (paradoxical) reflux in the Giacomini vein is a rare but well described pattern of reflux. Treatment of this type of reflux is controversial and only surgical treatment has been described. REPORT: We describe 2 patients in whom this type of reflux was successfully abolished following endovenous laser ablation (EVLA) of the GSV with the SPJ and Giacomini vein regaining competency...

BACKGROUND: Previous studies have suggested that the process of HIV-1 tRNA primer selection and encapsidation of genomic RNA might be coupled with viral translation. In order to further investigate this relationship, proviruses were constructed in which the primer-binding site (PBS) was altered to be complementary to elongator tRNAMet (tRNAMet(e)) (HXB2-Met(e)) or initiator tRNAMet (tRNAMet(i)) (HXB2-Met(i)). These tRNAMet not only differ with respect to the 3' terminal 18-nucleotides, but also with respect to interaction with host cell proteins during protein synthesis...
