Petiveria alliacea L. (Phytolacaceae) is a medicinal plant with a broad range of traditional therapeutic properties, including the treatment of dysentery and intestinal infections caused by protozoan parasites. However its effects against Entamoeba histolytica have not been reported yet. We here investigated the antiamoebic activity present in the leaves of P. alliacea L. Antiamoebic activity was evaluated in methanolic and aqueous extract, as well as in the hexanic, methanolic and EtOAc fractions. P. alliacea L...

OBJECTIVE/METHOD: The first manifestation of sarcoidosis is usually at the pulmonary level. The case is described of a 40-year-old female patient, who presented with an increased volume of the lacrimal gland and mechanical ptosis of upper left eyelid as the first expression of this disease. RESULT/CONCLUSION: The diagnosis of systemic sarcoidosis with primary presentation of the lacrimal gland was made after performing several immunological studies with negative results, imaging studies, and taking of glandular and lymph node biopsies...

Ubiquitination tags proteins for different functions within the cell. One of the most abundant and studied ubiquitin modification is the Lys48 polyubiquitin chain that modifies proteins for their destruction by proteasome. In Plasmodium is proposed that post-translational regulation is fundamental for parasite development during its complex life-cycle; thus, the objective of this work was to analyze the ubiquitination during Plasmodium chabaudi intraerythrocytic stages. Ubiquitinated proteins were detected during intraerythrocytic stages of Plasmodium chabaudi by immunofluorescent microscopy, bidimensional electrophoresis (2-DE) combined with immunoblotting and mass spectrometry...

BACKGROUND: A commonly used approach to improve recombinant protein production is to increase the levels of expression by providing extra-copies of a heterologous gene. In Komagataella phaffii (Pichia pastoris) this is usually accomplished by transforming cells with an expression vector carrying a drug-resistance marker following a screening for multicopy clones on plates with increasingly higher concentrations of an antibiotic. Alternatively, defective auxotrophic markers can be used for the same purpose...

The prostate-specific membrane antigen (PSMA) is expressed in epithelial cells of the prostate and highly overexpressed in 95% of advanced prostate cancers. The aims of this study was to estimate the biokinetics and dosimetry of (99m)Tc-EDDA/HYNIC-iPSMA ((99m)Tc-labeled PSMA inhibitor) in eight healthy subjects and evaluate its usefulness as a tumor-imaging agent in eight prostate cancer patients. METHODS: (99m)Tc-EDDA/HYNIC-iPSMA was obtained from a lyophilized formulation with radiochemical purities >98%, determined by reversed-phase HPLC and ITLC-SG analyses...

INTRODUCTION: As the civil war in Syria enters its fifth year, the Israeli government continues to provide humanitarian aid to Syrian civilians in Israeli hospitals. Many wounded Syrian children are treated at the Galilee Medical Center (GMC). Due to the patients' incomplete medical history and increasing infection rates in Syria, contact isolation and screening cultures for multi-drug resistant bacteria (MDR's) are conducted upon admission for all Syrian children. AIMS: To describe the rate of MDR carriage in Syrian children and compare it to hospitalized Israeli children...

Evidence suggests that patients with hip fractures should begin rehabilitation no later than six days following surgery. The reality is often far different. In an initiative led by the Greater Toronto Area (GTA) Rehab Network, acute care and rehab/complex continuing care hospitals across the GTA have implemented a new early referral process to aid transition of patients from acute care to inpatient rehabilitation as early as possible to improve their outcomes. Two of the participating acute care hospitals have now surpassed the six-day target and two others are within range...

Interfacing proteins with electrode surfaces is important for the field of bioelectronics. Here, a general concept based on phage display is presented to evolve small peptide binders for immobilizing and orienting large protein complexes on semiconducting substrates. Employing this method, photosystem I is incorporated into solid-state biophotovoltaic cells.

Acrospiroma, also known as hidradenoma, is a rare cutaneous tumor that has several histological characteristics. As a consequence, a high index of suspicion is necessary for its diagnosis. Here we report a case that illustrates the importance of a good clinical-pathologic correlation in order to recognize this disease.

In Paraguay, pesticides are the causative agent in 13.7% of poisonings, especially organophosphorus compounds. Such poisoning produces the inhibition of acetylcholinesterase generating three possible clinical conditions: acute poisoning, intermediate syndrome or late neurotoxicity. We present 15 cases of acute poisoning, ten women and five men from a rural community between 5 and 67 years of age, whose symptoms began after using water contaminated by pesticides from the community network. The most common symptoms were nausea and vomiting, followed by abdominal pain, headache, fever, itching, red eyes and sweating...

The Hippo pathway regulates cell proliferation and apoptosis and it has been noted that loss of critical components of this pathway can lead to uncontrolled cell growth. Yes-associated protein (YAP) is an important component of this Hippo pathway because YAP is the nuclear effector of the Hippo tumor suppressor pathway and it is crucial for the response to oxidative stress induced by cellular process and by different xenobiotics, including arsenic. It has been proposed that YAP dysregulation can contribute to a malignant cellular phenotype acting as both a tumor suppressor and an oncogene...

The present study reports the occurrence of the genus Belonolaimus in the state of Sinaloa, Mexico, associated with native plants (i.e., Ziziphus amole and Stenocereus alamosensis) in a natural coastal ecosystem. Both morphological and molecular approaches were employed to characterize the Sinaloa population. Notwithstanding of some morphological and morphometric variation between Belonolaimus from Sinaloa and other valid species, the characterization indicates that this population might belong to the Belonolaimus longicaudatus species complex...

Postharvest losses of fruits and vegetables can reach up to 25% in developed and up to 50% in developing countries. (Sub)tropical fruits are especially susceptible because their protecting peel can easily be damaged. Traditionally used pesticides are associated to environmental pollution and possible harmful health effects. An alternative are biocontrol agents (BCA), means bacteria or yeasts applied onto the fruits to inhibit the growth of phytopathogens. Many reports on their effectiveness have been published, however, reports on their harmlessness to consumers are still rare...

A novel targeted drug delivery nanoparticle system based on poly(D,L-lactide-co-glycolide) acid (PLGA) for delivery of doxorubicin (DOX) was developed. DOX-PLGA NPs were obtained by the emulsification-solvent evaporation technique. Then, their surface was modified with poly(L-γ-glutamic acid) (γ-PGA) and finally conjugated to modified folic acid (FA) as a targeting ligand. The surface modification and FA conjugation were followed by UV-Vis and FT-IR spectroscopies. Morphology was observed by TEM/SEM. Particle size, PDI and zeta potential were measured using DLS studies...

Downy mildew pathogens affect several economically important crops worldwide but, due to their obligate nature, few genetic resources are available for genomic and population analyses. Draft genomes for emergent downy mildew pathogens such as the oomycete Pseudoperonospora cubensis, causal agent of cucurbit downy mildew, have been published and can be used to perform comparative genomic analysis and develop tools such as microsatellites to characterize pathogen population structure. We used bioinformatics to identify 2,738 microsatellites in the P...

BACKGROUND: Odontogenic cysts (OC) are the most frequent lesions of the jaws and their constant epidemiological update is necessary and indispensable. Therefore the principal objective of this report was To determine prevalence and clinical-demographical characteristics of OC in a Mexican sample. MATERIAL AND METHODS: 753 cases of OC coming from the archive of a head and neck histopathological teaching service, from January 2000 to December 2013, were included. OC cases were re-assessed according 2005 WHO classification...
