Horizontal Natural Product Transfer: The Origin of the Widespread Alkaloidal Contaminations of Herbal Products
Alarmed by numerous worrying reports by the European Food Safety Authority related to widespread contaminations of
plant-derived commodities by poisonous alkaloids (nicotine, pyrrolizidine alkaloids), the sources of these alkaloidal contaminations were investigated. Our studies revealed that alkaloids, which have been leached out from decomposing alkaloidal
donor plants, are taken up by the roots of acceptor plants growing in their vicinity. Based on these results the so-called “Horizontal Natural Product Transfer
7,8-Dihydroxyflavone Affects Cellular Behavior of PC12 Cells
The BDNF/TrkB signaling is a robust regulatory feature of neuronal cells that promotes survival, differentiation, and proliferation in a variety of cell types and animal models for neurodegenerative diseases. The activation of TrkB by BDNF in clinical trials is accompanied by remarkable side effects and appears to be challenging due to BDNF's adverse molecular profile
Evaluation of The Viability and Phenotipe of Adipose Derived Cells Harvested Using Different Harvesting and Processing Procedures: A Pilot Study
Abstract
Background: Clinical studies demonstrated the efficacy of therapies based on the autologous grafting of adult mesenchymal stem cells to accelerate the healing and regenerative processes of the skin and mesenchymal tissues therefore, this is
considered a valuable approach in the aesthetic rejuvenation treatment to give volume restoration and skin regeneration
effects.
Objective: The aim of this project consists of the evaluation of the cell viability of adipose tissue (AT) harvested using
the Superficial Enhanced Fluid Fat Injection (SEFFI) procedure standardized by the Authors (AG, FPB). The harvesting
procedure was performed using two different cannulas having 0.8 mm and 1 mm side-port holes, respectively. Cells phenotype and ability to adhere to the plastic surface have been analysed. The results have been compared to those recorded
in adipose tissue harvested using a liposuction system and processed with enzymatic digestion (collagenase).
Methods: This study was performed on adipose tissues harvested from 7 patients (6 females and 1 male) with an average
age of 48.5 years with two different techniques and three different cannulas. We compared the cell vitality of every sample
at T0 and T72. Moreover, the samples were analysed to determine the phenotype: cells were incubated with antibodies
anti human against CD90-FITC, CD73-PeCy7, CD44-PE, CD31-PECy5, CD235a- PECy7, CD34-FITC, CD45-FITC and
CD146-FITC and read using the flow cytometer s3e Cell Sorter, BioRad. Results were analysed using the software Flow Jo.
Effects of Transfer Factor Supplementation on Immune Reactions in Mice
Colostrum-derived transfer factors are among the highest potential natural immunostimulatory food supplements. In our study, we evaluated the possible effects of supplementation with various compositions that included transfer factors in phagocytosis, TNF-α and IL-2 secretion, antibody formation and NK cells activity. We found significant improvements of all these immune reactions after 7 days of supplementation.
Computer Modeling of Convective Mass Transfer of Glucose, Oxygen and Carbon Dioxide in the Neurovascular Unit
Glucose and oxygen are obligatory energy substrates for the brain and their continuous supply to the neurons, as well as the elimination of the end product – carbon dioxide, is of paramount importance for brain physiology and survival. Transport of these substrates from the brain capillaries to the neurons presents a challenging issue.
Occurrences of Dairy Calf Mortality and Morbidity and the Associated Risk Factors in Sululta and its Environs, Central Ethiopia
Calf morbidity and mortality are important causes of economic losses on dairy farms worldwide. A cross-sectional study and clinical observation was conducted from November 2016 to April 2017 with the objective of determining calf morbidity and mortality and to investigate the potential risk factors for mortality and morbidity in Sululta and its environs. A total of 312 respondents engaged in market oriented small holder dairying were interviewed using a structured questionnaire survey about their farm and calf management practices and major calf health problems encountered and diseases that causes mortality. The overall magnitude of morbidity and mortality of calves were 31.0% and 58.37%, respectively. The major calf diseases found were diarrhea (69.34%), pneumonia (16.54%), liver fluke (2.4%), bloat (2.0%), joint ill (2.4%) and other cases (8.04%). Risk factors such as weaning age, breed and awareness of colostrums, feeding of calf and overall farm management were included. In this study 80.3% of calf mortality occurs under age 3 month and 19.42% is above 3 month. Based on laboratory examination, Salmonella and E.coli were detected from diarrheic calves. Salmonella found at rate of 2/29 (3.6%) and E.coli found at only genus level. In conclusion, the magnitude of calf morbidity and mortality found in this study were much higher than economically tolerable level and could greatly affect the productivity of the dairy farms through mainly decreasing the availability of replacement stock and production of milk. It is therefore, suggested that implementation of improved calf and farm management practices and proper environmental protection in the study areas would significantly reduce calf mortality and morbidity.
Efficacy of Purified Glutathione -S- Transferee in Providing Protection against Haemonchus Contortus Infection in Sheep
The efficacy of purified glutathione-s-transferase (GST) to protect sheep against haemonchosis was assessed. Fifteen lambs, 3.5-5month-old, were bisected into five groups (n=3). Two groups were vaccinated with 250μg of each prepared antigen (crude adult antigen (CAA), purified GST) in combination with mineral oil adjuvant at zero, 14th days of the experiment. The other three groups were kept as control groups; non-immunized infected, non-immunized non-infected and adjuvant control. One week after the last booster dose, the lambs in all groups except control negative were challenged with 400 L3/kg live weight orally. Protein characterization of each antigen was done by SDS-PAGE and immunoblting. The vaccine efficacy was estimated by the fecal egg count, where the vaccinated groups showed 58.90% and 79.38% reduction in eggs in CAA and GST respectively. Moreover, 31.45% and 92.10% reduction in abomasal worm count was reported in CAA and GST vaccinated lambs, respectively. The protection was found corresponsive to the sera antibody levels in the immunized groups. It was concluded that the GST had protective efficacy against H. contortus infection in lambs.
Detection of the Triclorfon Base on Bioluminescence Resonance Transfer among Functional CdZnSe/ZnS Quantum Dots
The synthesis of ternary quantum dots (TQDs) have a significant effect on the use of nano scale crystals in biology, photonics and photovoltaic. Rather than controlling the size of TQDs, making three-component TQDs is also an approach to changing the energy of their barrier width, typically using three-component substances such as Znx Cd1-xSe.
