Proximate Composition and Quality Characterization of Oil Extracted From Moringa Oleifera Kernel Using Different Extraction Method

This study investigates proximate composition and characterization of Moringa oleifera seed-oil using four methods of extraction (Cold pressing (CP), Enzyme assisted cold pressing (EACP), Enzyme assisted aqueous extraction (EAAE) and solvent extraction (SE)) and compared with olive oil. The results of proximate analysis of the kernel reveals (7.20 moisture content, 43.12 protein, 33.16 fat, 3.51 Ash, and 6.81 Carbohydrate by difference) %, while the oil yield obtained for CP, EACP, EAAE and SE were (7.75, 12.08, 23.25 and 33.16)%. The fatty acids composition and bioactive compounds were determined through GC-MS analysis. Melting and crystallization temperature ranges: -15.86 to 3.21 and 8.30 to -13.63 °C, respectively. There is a significant difference in term of oil yield, with cold pressing method having the lowest oil yield of 7.8 %. However, the quality of CP extracted Moringa oleifera oil was compared with virgin olive oil; it revealed its potentials as a good source of oleic acid making it to be a good substitute for virgin olive oil.

Acute Disseminated Encephalomyelitis (ADEM): Short Term Motor Outcome of Hospital Admitted Patients

Introduction: Among the neuroinflammatory disorder of CNS, Acute Disseminated Encephalomyelitis (ADEM) is a multifocal, subacute or acute onset disease that has got current interest of neurologists for its better outcome. Very few studies have been carried out on ADEM particularly in adults of our country. So we performed the study to describe short term motor outcome of hospital admitted ADEM patients.

Liquid Biopsy in Advanced Gastric Malignancy and Molecular Targeted Therapy; a Case Report and Update Pertaining Anti HER2-Neu Therapy

Human epidermal growth factor receptor 2 (HER2) is responsible for the pathogenesis and poor outcomes of several types of cancers, including advanced gastric and gastroesophageal junction cancer. Molecular-targeted drugs on the other hand, such as trastuzumab, prolong overall survival and progression-free survival in HER2-positive gastric cancer. The purpose of the case report is to evaluate the impact of delivering trastuzumab in advanced gastric cancer with concomitant HER2 mutation and amplification.

A Non-Contact Passive Approach for the Effective Collection of Target Explosive Volatiles for Canine Training Aid Development

The use of real explosive materials for canine training involves inherent dangers, toxicity risks exposure, and often limited availability of the training material all of which may affect the reliable training of canine teams. For this reason, the development of a training aid suitable for daily operations is beneficial to provide safe and effective explosive detection training that can provide for enhanced detection capabilities.

Mitochondrial Actions for Fat Browning and Energy Expenditure in White Adipose Tissue

White adipose tissue (WAT) is an endocrine organ with crucial role in the development of obesity and related diseases. White adipocytes have less mitochondria than brown adipocytes; nevertheless, there is an increasing body of evidence showing that mitochondrial parameters play a relevant role in WAT physiology, such as proliferation, differentiation and triacylglycerol storage levels.

Formulation and Evalution of Oral Reconstitutable Suspension of Cefpodoxime Proxetil

Cefpodoxime proxetil (CFPD PRXL) is broad spectrum, third generation cephalosporin; antibiotic. It is extremely bitter taste resulting in poor patient compliance. The aim of the present work was to prepare drug resin complex (DRC) using ion exchange resin (Kyron T-114) for taste masking and formulate oral reconstitutable suspension of DRC.

Non-ARV Prescriptions and Medication Burden among Commercially Insured U.S. HIV Patients

Accelerated aging and higher co-morbidity prevalence have increased non-antiretroviral (ARV) medications for HIV patients. We examined, over a 12 month period, non-ARV medication burden among HIV-positive patients 18-49 and ≥50 years using a comprehensive U.S. healthcare claims database in an age-and-gender matched analysis (1:3 matching ratio of cases to controls). Primary outcomes of interest included the median and mean number of unique non-ARV drug substances during the one month period with the highest number of prescriptions filled for each individual, and the mean number of unique classes of medication.

NMR Assignment of N-(1-adamantyl)-1-pentyl-1H-indazole-3-carboxamide Seized as Herbal Incense for the First Time in Italy

The synthetic cannabinoid, N-(1-adamantyl)-1-pentyl-1H-indazole-3-carboxamide, known also as AKB48 and/or APINACA, has been detected for the first time in herbal incense seized in Italy. Its structural characterization has been performed through gas chromatography-mass spectrometry (GC-MS) and high-resolution nuclear magnetic resonance (NMR) analysis. In order to favor an easier and faster identification of AKB48 in future investigations, NMR assignments in deuterated methanol and chloroform is also reported.
