OBJECTIVES: Postpartum period is a critical period to address high unmet needs of family planning and to reduce the risks of closely spaced pregnancies. However, contraception during extended postpartum period has given less emphasis concerning contraceptive practice in Ethiopia. Therefore, this study was aimed to assess postpartum modern contraceptive use and associated factors among postpartum women in Northern Ethiopia. METHODS: A community based cross sectional study was done from March to April, 2015...

Ajamaluddin Malik
Disulfide bonds occurred in majority of secreted protein. Formation of correct disulfide bonds are must for achieving native conformation, solubility and activity. Production of recombinant proteins containing disulfide bond for therapeutic, diagnostic and various other purposes is a challenging task of research. Production of such proteins in the reducing cytosolic compartment of E. coli usually ends up in inclusion bodies formation. Refolding of inclusion bodies can be difficult, time and labor consuming and uneconomical...

Platelets are critical for haemostasis, thrombosis, and inflammatory responses, but the events that lead to mature platelet production remain incompletely understood. The bone marrow has been proposed to be a major site of platelet production, although there is indirect evidence that the lungs might also contribute to platelet biogenesis. Here, by directly imaging the lung microcirculation in mice, we show that a large number of megakaryocytes circulate through the lungs, where they dynamically release platelets...

OBJECTIVES: Totally endoscopic minimally invasive mitral valve surgery (MIMVS) is technically demanding and often performed with robotic assistance. We hypothesized that three-port video-assisted thoracic surgery (VATS) would facilitate endoscopic MIMVS and evaluated its feasibility and safety. METHODS: From October 2010 to June 2016, we performed first-time MIMVS in 250 consecutive patients (122 male), with median age of 65 years (54-73 years, 25-75 percentile)...

Background: Task modification refers to performing a task differently than before. While task modification in walking may be a sign of looming walking difficulty, it may also be adaptive in and postpone the decline in life-space mobility. However, this has not been studied. This study examined whether changes in life-space mobility over a 2-year period differ between people who at baseline report no walking difficulty and no task modification, those who report no walking difficulty but task modification, and those who report walking difficulty...

Although sponges are important components of benthic ecosystems of the Caribbean Sea, their diversity remained poorly investigated in the Lesser Antilles. By organizing a training course in Martinique, we wanted both to promote taxonomy and to provide a first inventory of the sponge diversity on this island. The course was like a naturalist expedition, with a field laboratory and a classroom nearby. Early-career scientists and environmental managers were trained in sponge taxonomy. We gathered unpublished data and conducted an inventory at 13 coastal sites...

Single nucleotide polymorphisms (SNPs) are widely used in genetics and genomics research. The Pacific oyster (Crassostrea gigas) is an economically and ecologically important marine bivalve, and it possesses one of the highest levels of genomic DNA variation among animal species. Pacific oyster SNPs have been extensively investigated; however, the mechanisms by which these SNPs may be used in a high-throughput, transferable, and economical manner remain to be elucidated. Here, we constructed an oyster 190K SNP array using Affymetrix Axiom genotyping technology...

The genus Dipsacus is characterized by a remarkable bidirectional flowering sequence and a rare phyllotactic pattern. Considering that flower initiation and flowering sequence may be interconnected, we document the development of the head meristem in Dipsacus fullonum. Our results indicate a gradual change in the geometry of the head meristem beginning with a dome shaped stage, continuing with a remarkable widening in the middle part of the head meristem and ending in a spindle-like form. Quantitative data confirm that meristem expansion is higher in the middle part than at the base of the meristem...

Todani classification is extensively used to guide the surgical strategy of choledochal cysts, but no systematic investigations on the distal management of intrapancreatic choledochal cysts have been conducted. This study reports the distal classification and management of choledochal cysts in adults based on the relation between the cyst and pancreatic duct. Patients with choledochal cyst who underwent operation, including distal management, in our department from January 2009 to December 2014 were retrospectively reviewed...

BACKGROUND: Telemedicine, the use of information technology and telecommunication to provide healthcare at a distance, is a burgeoning field with applications throughout medicine. Given the visual nature of plastic surgery and dermatology, telemedicine has a myriad of potential applications within the field. METHODS: A comprehensive literature review of articles published on telemedicine since January 2010 was performed. Articles were selected for their relevance to plastic and reconstructive surgery and dermatology, and then reviewed for their discussion of the applications, benefits, and limitations of telemedicine in practice...

An 82-year-old woman who had a history of essential thrombocythemia presented with ocular pain, bleeding, and decreased visual acuity of the left eye. Orbital computed tomography revealed a relatively well-defined homogenous mass-like lesion in the left subconjunctival and intraconal space. Conjunctival biopsy showed acute inflammation with necrosis, vascular ectasia with thrombosis and hemorrhage. After the treatment with hydroxyurea and anagrelide, her symptom and lesion were markedly improved. Hematologic disorders like essential thrombocythemia should be considered in patients with severe spontaneous bleeding around the eye...

Venous air embolism is a rare but recognized complication of posterior spinal fusion surgery and epidural placement using a loss of resistance to air technique. We report a case of a probable venous air embolism causing cardiac arrest in a 10-year-old girl undergoing posterior spinal fusion in the prone position. The most likely source of the embolism was injection of air into the epidural space from a loss of resistance to air technique. This case also demonstrates the potential for paradoxical cerebral embolism in the absence of an intracardiac defect...

Typical dimensionality reduction (DR) methods are data-oriented, focusing on directly reducing the number of random variables (or features) while retaining the maximal variations in the high-dimensional data. Targeting unsupervised situations, this paper aims to address the problem from a novel perspective and considers model-oriented DR in parameter spaces of binary multivariate distributions. Specifically, we propose a general parameter reduction criterion, called confident-information-first (CIF) principle, to maximally preserve confident parameters and rule out less confident ones...

In Part I of the paper, we detected elements blocked by ribs during simulated and in vivo transcostal liver scans, and we turned those elements off to compensate for the loss in visibility of liver vasculature. Here, we apply blocked-element detection and adaptive compensation to large synthetic aperture data collected through rib samples ex vivo, in order to reduce near-field clutter and to recover lateral resolution. To construct large synthetic transmit and receive apertures, we collected the individual channel signals from a fully-sampled matrix array at multiple and know array locations across the tissue samples...

Magnetic resonance electrical property tomography (MREPT) is a technique used to extract the electrical properties of tissues (conductivity in particular) using a magnetic resonance imaging (MRI) system. In this work, we propose an improved data acquisition scheme for electrical property tomography technique by utilizing T2 modulation in fast spin echo (FSE) imaging. This technique was motivated by numerical analysis of conductivity reconstruction in the frequency domain; results reveal the spatial frequency-dependent noise texture of conventional methods...
