It is well known for Chikungunya fever to present as myriad of skin rash along with usual joint pain and fever, but probably this is the first case report of Chikungunya fever presenting as severe life threatening thrombotic microangiopathy, thrombotic thrombocytopenic purpura leading to multiple areas of skin necrosis, peripheral digital gangrene, haemolytic anemia, renal failure and severe thrombocytopenia with bleeding. This complication was most likely due to inhibitor autoantibody formation against ADAMTS13 triggered by chikungunya virus leading to thrombotic thrombocytopenic purpura...

BACKGROUND: The clinical morphology of anogenital warts may vary from flat, filiform, papular, or verrucous to giant condyloma acuminatum. Clinically atypical-looking genital warts may alarm the clinician because of their suspected malignant potential, which may cause anxiety, often leading to aggressive interventions. OBJECTIVE: To study if clinically atypical-looking anogenital warts are more likely to be premalignant or malignant as compared to typical warts...

The Gulf of Aqaba is an oligotrophic marine system with oxygen-rich water column and organic carbon-poor sediments (≤0.6% at sites that are not influenced by anthropogenic impact). Aeolian dust deposition from the Arabian, Sinai, and Sahara Deserts is an important source of sediment, especially at the deep-water sites of the Gulf, which are less affected by sediment transport from the Arava Desert during seasonal flash floods. Microbial sulfate reduction in sediments is inferred from the presence of pyrite (although at relatively low concentrations), the presence of sulfide oxidation intermediates, and by the sulfur isotopic composition of sulfate and solid-phase sulfides...

BACKGROUND: The influence of various biochars on crop yield and disease resistance of Capsicum anuum L. (sweet pepper) under modern, high-input, intensive net house cultivation was tested over the course of 2011 to 2014 in the Arava desert region of Israel. A pot experiment with Lactuca sativa L. (lettuce) grown in the absence of fertilizer employed the 3-year old field trial soils to determine if biochar treatments contributed to soil intrinsic fertility. RESULTS: Biochar amendments resulted in a significant increase in number and weight of pepper fruits over three years...

Members of the yeast family of PUF proteins bind unique subsets of mRNA targets that encode proteins with common functions. They therefore became a paradigm for post-transcriptional gene control. To provide new insights into the roles of the seemingly redundant Puf1 and Puf2 members, we monitored the growth rates of their deletions under many different stress conditions. A differential effect was observed at high CaCl2 concentrations, whereby puf1Δ growth was affected much more than puf2Δ, and inhibition was exacerbated in puf1Δpuf2Δ double knockout...

REVIEW
Michal Solomon, Eli Schwartz
Leishmaniasis is endemic in Israel and is increasing in its frequency. The pathogens that cause cutaneous leishmaniasis (CL) in Israel are Leishmania major (L. major) and Leishmania tropica (L. tropica). In recent years, there have been significant changes in the distribution of these species. L. major is endemic mainly in the Negev, Arava and the Beit She'an Valley. L. tropica is endemic in Tiberias, northern Sea of Galilee, Samaria and in the vicinity of Jerusalem such as at Kfar Adumim, Ma'ale Adumim and Anathoth (north-east of Jerusalem)...

Sugars affect central aspects of plant physiology, including photosynthesis, stomatal behavior and the loss of water through the stomata. Yet, the potential effects of sugars on plant aquaporins (AQPs) and water conductance have not been examined. We used database and transcriptional analyses, as well as cellular and whole-plant functional techniques to examine the link between sugar-related genes and AQPs. Database analyses revealed a high level of correlation between the expression of AQPs and that of sugar-related genes, including the Arabidopsis hexokinases 1 (AtHXK1)...

This article presents an open data repository, the methodology to generate it and the associated data processing software developed to consolidate an hourly snapshot historical data set for the year 2015 to an equivalent Nordic power grid model (aka Nordic 44), the consolidation was achieved by matching the model׳s physical response w.r.t historical power flow records in the bidding regions of the Nordic grid that are available from the Nordic electricity market agent, Nord Pool. The model is made available in the form of CIM v14, Modelica and PSS/E (Siemens PTI) files...

Enolonium species/iodo(III)enolates of carbonyl compounds have been suggested to be intermediates in a wide variety of hypervalent iodine induced chemical transformations of ketones, including α-C-O, α-C-N, α-C-C, and α-carbon-halide bond formation, but they have never been characterized. We report that these elusive umpoled enolates may be made as discrete species that are stable for several minutes at -78 °C, and report the first spectroscopic identification of such species. It is shown that enolonium species are direct intermediates in C-O, C-N, C-Cl, and C-C bond forming reactions...

Dysregulated expression of lysosomal cysteine cathepsins is associated with adverse cardiac remodeling, a characteristic of several cardiovascular diseases. However, the information regarding the role of cysteine cathepsin L (CTSL) and cathepsin B (CTSB) in dilated cardiomyopathy (DCM) is limited. The present study was aimed to investigate the expression of CTSL and CTSB in animal model of doxorubicin (doxo)-induced cardiomyopathy as well as in peripheral blood samples of DCM patients. Cardiac tissue sections from doxo-treated and control rats were used to study the expression of CTSL and CTSB by enzyme assay and immunohistochemistry (IHC)...

Lithium-sulfur (Li-S) chemistry is projected to be one of the most promising for next-generation battery technology, and controlling the inherent "polysulfide shuttle" process has become a key research topic in the field. Regulating intermediary polysulfide dissolution by understanding the metamorphosis is essential for realizing stable and high-energy-density Li-S batteries. As of yet, a clear consensus on the basic surface/interfacial properties of the sulfur electrode has not been achieved, although the catalytic phenomenon has been shown to result in enhanced cell stability...

RANDOMIZED CONTROLLED TRIAL

BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) as a standalone modality is superior to conventional TBNA (c-TBNA) for the diagnosis of sarcoidosis. However, the overall yield is not different if combined with endobronchial biopsy (EBB) and transbronchial lung biopsy (TBLB). The utility of rapid on-site evaluation (ROSE) in a comparative evaluation of EBUS-TBNA versus c-TBNA for the diagnosis of sarcoidosis has not been previously evaluated. METHODS: Eighty patients with suspected sarcoidosis were randomized 1:1:1:1 into 4 groups: c-TBNA without ROSE (TBNA-NR), c-TBNA with ROSE (TBNA-R), EBUS-TBNA without ROSE (EBUS-NR), and EBUS-TBNA with ROSE (EBUS-R)...

REVIEW
A Golani-Armon, Y Arava
The diverse functions of mitochondria depend on hundreds of different proteins. The vast majority of these proteins is encoded in the nucleus, translated in the cytosol, and must be imported into the organelle. Import was shown to occur after complete synthesis of the protein, with the assistance of cytosolic chaperones that maintain it in an unfolded state and target it to the mitochondrial translocase of the outer membrane (TOM complex). Recent studies, however, identified many mRNAs encoding mitochondrial proteins near the outer membrane of mitochondria...

BACKGROUND: Pulmonary alveolar proteinosis (PAP) is a rare disorder characterized by deposition of lipoproteinaceous material within alveoli, with a variable clinical course. Here, we report an experience of management of PAP at our center. A systematic review of previously reported cases from India is also included in the article. MATERIALS AND METHODS: This study included patients with primary PAP managed at our center from 2009 to 2015. Diagnosis of primary PAP was based on histopathologic diagnosis on bronchoalveolar lavage or transbronchial lung biopsy and absence of causes of secondary PAP...

The approach to an intrinsic cause of superior vena cava syndrome (SVCS) is usually difficult but rewarding. We report a case of a middle-aged man who presented with progressive oedema of the upper half of the body, dyspnoea, cough and weight loss for a 1-year duration. He was a non-smoker without prior hospitalisation. Chest radiography showed right-sided pleural effusion with an apparent normal superior mediastinum. Contrast-enhanced CT of the chest revealed a right atrial mass extending and completely obliterating to superior vena cava...
