Directed evolution experiments designed to improve the activity of a biocatalyst have increased in sophistication from the early days of completely random mutagenesis. Sequence-based and structure-based methods have been developed to identify "hotspot" positions that when randomized provide a higher frequency of beneficial mutations that improve activity. These focused mutagenesis methods reduce library sizes and therefore reduce screening burden, accelerating the rate of finding improved enzymes...

Unlike adult neurofibromatosis type 2 (NF2), which presents with symptoms related to bilateral vestibular schwannomas, children with NF2 most frequently present with ocular, dermatological, and neurological symptoms. Arteriopathy, a well-established feature in neurofibromatosis type 1, is not a widely recognized feature of NF2. Here we report three children with NF2 with cerebral arteriopathy and/or arterial ischaemic stroke. Bevacizumab, a vascular endothethial growth factor inhibitor, is an established treatment for rapidly growing vestibular schwannomas; however, it carries a risk of both ischaemic and haemorrhagic stroke...

The aim of this study was to investigate environmental and lifestyle factors affecting exposure to PAHs in the general population in a large city of the Middle East (Tehran) by measuring urinary monohydroxy polycyclic aromatic hydrocarbons (OH-PAHs) and establishing relationships between PAHs exposure and related factors. Urine samples were collected from 222 randomly chosen subjects who were living in the urban area of Tehran, Iran. Subjects were required to complete a detailed questionnaire aimed to document their personal and sociodemographic information, activities, cooking-related appliances, smoking history/exposure, and consumed foodstuff...

Clopidogrel is used in patients with coronary syndromes and at risk of thrombotic events or receiving percutaneous coronary intervention (PCI) for reducing heart attack and stroke. Here we present genotype and phenotype study of Iranian patients undergoing PCI treated with clopidogrel during a 6-month period of follow-up; common variants of CYP2C19, CYP3A5, CYP3A4, and ABCB1 genes were determined as well as the patients' cardiovascular outcomes to find out the effect of these variants individually and in combination...

Objective: Idiopathic granulomatous mastitis is a breast disease without a definitive etiology. There are no definitive classifications, scoring systems or certitudes. The aim of this study is to define the factors related to the recurrence and design a scoring system. Material and Methods: Patients who were admitted to the general surgery department with symptoms of granulomatous mastitis were evaluated by ultrasonography and underwent antibiotic therapy. Granulomatous mastitis is diagnosed by core biopsy and treated with steroid therapy...

On the 40th anniversary of the Alma Ata Declaration that affirmed health for all a right and primary health care the route to guarantee that right, WHO and PAHO have issued a call to action to convert universal health into reality for the nearly four billion people worldwide lacking full coverage of essential health services. There is some urgency to this movement: WHO estimates the health workforce shortage of nearly 8 million could reach almost 13 million by 2035. And the USA is not exempt: medical associations and special commissions set up to investigate the shortage of primary care physicians, especially "under-represented minority" doctors, have issued report after report on this growing health care emergency...

BACKGROUND: To stratify the risk of malignancy in thyroid incidentalomas detected on 18F-FDG PET/CT using ultrasound features according to guidelines for thyroid nodules and thereby suggests management plans. METHODS: From a historical cohort of 96 942 consecutive patients who underwent 18F-FDG PET/CT between October 2008 and September 2015, 1342 patients with 1364 nodules underwent ultrasound evaluation for focal uptake in thyroid gland, with a final diagnosis made for 877 patients with 907 nodules which included in our study...

The industrial importance of optically pure compounds has thrown a spotlight on ω-transaminases that have shown a high potential for the synthesis of bioactive compounds with a chiral amine moiety. The implementation of biocatalysts in industrial processes relies strongly on fast and cost effective process development, including selection of a biocatalyst form and the strategy for its immobilization. Here, microscale reactors with selected surface-immobilized amine-transaminase (ATA) in various forms are described as platforms for high-throughput process development...

Since the beginning of the epidemic, human immunodeficiency virus (HIV) has infected around 70 million people worldwide, most of whom reside is sub-Saharan Africa. There have been very promising developments in the treatment of HIV with anti-retroviral drug cocktails. However, drug resistance to anti-HIV drugs is emerging, and many people infected with HIV have adverse reactions or do not have ready access to currently available HIV chemotherapies. Thus, there is a need to discover new anti-HIV agents to supplement our current arsenal of anti-HIV drugs and to provide therapeutic options for populations with limited resources or access to currently efficacious chemotherapies...

Objective: Current literature indicates that the presence of clinical pharmacists in hospitals results in improved patient care, rational drug therapy, and treatment costs. This study assessed the clinical pharmacy services in the intensive care unit (ICU) of a tertiary hospital at Tabriz University of Medical Sciences, Iran. Methods: During a 9-month cross-sectional study (2014-2015), the clinical pharmacy interventions in 27 sessions and educational activities for patients and health-care professionals were randomly assessed based on the Australian guideline and standard of practice for clinical pharmacy...

OBJECTIVES: We aim to histopathologically analyze the effect of hyperbaric oxygen (HBO) therapy in the lung tissue. MATERIAL AND METHODS: A total of 21 rabbits were divided into three groups, with each containing seven rabbits. Group 1 was the control group. Group 2 underwent HBO of 3 atmosphere absolute (ATA) for 90 min/day for 7 days. In group 3, HBO at 3 ATA was administered 90 min/day for 28 days. Oxygen saturation (SpO2 ) was determined by pulse oximetry before and after administration of HBO...

INTRODUCTION AND AIM: There is an important link between platelets and inflammation, thrombosis, and vascular and tissue repair mechanisms. SCUBE1 (signal peptide-CUB-EGF domain-containing protein 1) may function as a novel platelet-endothelial adhesion molecule and play pathological roles in cardiovascular biology. Stent thrombosis (ST) following percutaneous coronary intervention is an uncommon and potentially catastrophic event that can manifest as myocardial infarction and sudden death...

The effectiveness of hyperbaric oxygen treatment for acute cardiac diseases is unknown. Similarly, the effectiveness of hyperbaric oxygen treatment for carbon monoxide intoxication is also unknown, particularly for cases in which carboxyhemoglobin (COHb) levels return to normal. Our case study revolved around a healthy twenty-year-old male patient, who suffered from carbon monoxide intoxication. The patient presented to the Emergency Department unconscious. Blood workup revealed significant carbon monoxide intoxication and cardiac injury (COHb = 41%, troponin T = 0...

Purpose: To analyze and compare the signals of bleeding from the use of direct-acting oral anticoagulants (DOACs) in the US Food and Drug Administration Adverse Event Reporting System (FAERS) database over 5 years. Methods: Reports of bleeding and of events with related terms submitted to the FAERS between October 2010 and September 2015 were retrieved and then analyzed using the reporting odds ratio (ROR). The signals of bleeding associated with DOAC use were compared with the signals of bleeding associated with warfarin use utilizing the FAERS databases...

BACKGROUND: Cytokine genes, including interleukin-10 (IL-10), are known to play important roles in the pathogenesis of juvenile idiopathic arthritis (JIA). This study aims to determine whether the IL-10 polymorphisms confer susceptibility to JIA. METHODS: A meta-analysis was performed on the associations between the IL-10 -1082 G/A, -592 C/A, and -819 C/T polymorphisms and JIA. A total number of 7 studies involving 1,785 patients and 6,142 controls were considered in the meta-analysis...
