BACKGROUND: The study was designed to explore any beneficial effect of Ocimum sanctum (Linn) (OS) in experimental pulmonary hypertension (PH) in rats. OS is commonly known as “holy basil” and “Tulsi” and is used in the Indian System of Medicine as antidiabetic, antioxidant, hepatoprotective, adaptogenic, and cardioprotective. METHODS: Monocrotaline (MCT) administration caused development of PH in rats after 28 days and rats were observed for 42 days...

Genetic diversity and structure of populations at the edge of the species' spatial distribution are important for potential adaptation to environmental changes and consequently, for the long-term survival of the species. Here, we combined classical population genetic methods with newly developed network analyses to gain complementary insights into the genetic structure and diversity of Acacia tortilis, a keystone desert tree, at the northern edge of its global distribution, where the population is under threat from climatic, ecological, and anthropogenic changes...

Nanomagnets are a promising low-power alternative to traditional computing. However, the successful implementation of nanomagnets in logic gates has been hindered so far by a lack of reliability. Here, we present a novel design with dipolar-coupled nanomagnets arranged on a square lattice to (i) support transfer of information and (ii) perform logic operations. We introduce a thermal protocol, using thermally active nanomagnets as a means to perform computation. Within this scheme, the nanomagnets are initialized by a global magnetic field and thermally relax on raising the temperature with a resistive heater...

PURPOSE: In this study non-calcified plaque composition is evaluated by Dual Energy CT (DECT). Energy Dispersive X-ray Spectroscopy (EDS) has been used to study the Plaque composition. An attempt has been made to explain the DECT results with EDS analysis. METHODS: Thirty-two ex-vivo human cadaver coronary artery samples were scanned by DECT and data was evaluated to calculate their effective atomic number and electron density (Zeff & ρe ) by inversion method...

During October 2014, unfamiliar mild mosaic and mottling symptoms were identified on leaves of pepper (Capsicum chinense cv. Habanero) seedlings grown in the Arava valley in Israel 2-3 weeks post planting. Symptomatic plants were tested positive by ELISA using laboratory-produced antisera for tobamovirus species. Typical tobamovirus rod-shaped morphology was observed by transmission electron microscopy (TEM) analysis of purified virion preparation that was used for mechanical inoculation of laboratory test plants for the completion of Koch's postulates...

Ribosome queuing is a fundamental phenomenon suggested to be related to topics such as genome evolution, synthetic biology, gene expression regulation, intracellular biophysics, and more. However, this phenomenon hasn't been quantified yet at a genomic level. Nevertheless, methodologies for studying translation (e.g. ribosome footprints) are usually calibrated to capture only single ribosome protected footprints (mRPFs) and thus limited in their ability to detect ribosome queuing. On the other hand, most of the models in the field assume and analyze a certain level of queuing...

Cardiac myxomas are benign neoplasm of the heart with an incidence of 0.3%. Glandular cardiac myxomas are very rare and accounts for less than 3% of all cardiac myxomas. Here, we report a case of familial glandular cardiac myxoma in a 35 year old male who complained of exertional dyspneoa and weakness of right side of body on clinical presentation. Associated features of Carney's complex were not present. Family history revealed presence of cardiac myxoma in younger brother and sister. Transthoracic echocardiography detected biatrial myxoma...

Along the arid Arava, southern Israel, acacia trees (Acacia raddiana and Acacia tortilis) are considered keystone species. Yet they are threatened by the ongoing aquifer depletion for agriculture, the conversion of natural land to agricultural land, seed infestation by bruchid beetles, and the reduction in precipitation level in the region. In the acacia dominated Evrona reserve (southern Arava), adding to these threats are recurrent oil spills from an underground pipeline. We report here a study of the effects of contaminated soils, from a recent (December 2014) and a much older (1975) oil spills...

BACKGROUND: Thromboembolic events are the major cause of morbidity and mortality in patients with mitral stenosis (MS). This study aims to investigate left atrial spontaneous echo contrast (LA SEC), mitral annular systolic velocity (Sa-wave), left atrial appendage (LAA) late emptying velocity (LAAEV), LAA filling velocity (LAAFV) pre- and postpercutaneous balloon mitral valvuloplasty (PBMV) for MS. This also aims to study the association of LA SEC with inflammatory marker, high-sensitivity C-reactive protein (hs-CRP) in MS...

Synthesis of β-sulfinamido ketones was accomplished by the addition of silyl enol ethers derived from arylmethyl ketones to chiral sulfinimines in excellent yield and selectivity. Application of the formed β-amino substituted ketones is exemplified in the total synthesis of sphingolipid HPA-12 and the sedamine alkaloids.

INTRODUCTION: Increased expression of Programmed death ligand-1 (PD-L1) on cancer cells and immune cells predict response to PD-1/PDL1 inhibitors. Data regarding frequency and pattern of PD-L1 expression in NSCLC from India is not available. OBJECTIVES: To analyse PD-L1 expression on tumour cells (TC) and immune cells (IC) and to correlate PD-L1 expression with baseline clinico-pathological characteristics, oncogenic drivers and outcome data. MATERIALS AND METHODS: PD-L1 expression on tumour cells and immune cells was analysed...

BACKGROUND: Sensitivity to macrocyclic lactones, which are commonly used in veterinary clinics, was first found in Rough Collies, and was attributed in 2001 to a 4 bp deletion in the MDR1 gene. The list of affected breeds currently includes 13 breeds. Researchers from different countries and continents examined the allelic frequencies of the nt230(del4) MDR1 mutation, emphasizing the clinical importance of this test not only to mutation-prone dogs, but also to their crosses and mongrels, since treatment of a deletion carrier with these compounds may lead to its death...

A 26-year-old smoker male presented with a history of sudden onset dyspnea and right-sided chest pain. Chest radiograph revealed large right-sided pneumothorax which was managed with tube thoracostomy. High-resolution computed tomography thorax revealed multiple lung cysts, and for a definite diagnosis, a video-assisted thoracoscopic surgery-guided lung biopsy was performed followed by pleurodesis. This clinicopathologic conference discusses the clinical and radiological differential diagnoses, utility of lung biopsy, and management options for patients with such a clinical presentation...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive and efficacious diagnostic modality for lung cancer staging and evaluation of undiagnosed mediastinal lymphadenopathy. Procedure-related complications are uncommon. We herein report an infrequently described phenomenon following EBUS-TBNA in which two patients developed nodular granulation tissue at the tracheobronchial puncture site. On systematic review, we found description of such phenomena by terminologies such as endobronchial inflammatory polyp, granuloma, and endobronchial mass...

BACKGROUND: Lichen planus pigmentosus (LPP) is a common cause of facial melanosis in the dark-skinned population. At present, information on dermoscopy and patch testing in LPP is limited. OBJECTIVES: To describe dermoscopic findings and study the role of patch testing in patients with LPP on the face. METHODS: Facial lesions of 50 patients with LPP were studied dermoscopically, followed by histological evaluation. Patch and photopatch tests with the Indian Standard Series and Scandinavian series, respectively, and patient's own cosmetics were performed on all patients...
