Carbon (C) storage potential was quantified for four tree species which are commonly incorporated into tree-based intercropping (TBI) systems and compared with conventional agricultural systems in southern Ontario, Canada. In the 31-year-old TBI system at the University of Guelph's Agroforestry Research Station, Norway spruce (Picea abies), white cedar (Thuja occidentalis), black walnut (Juglans nigra) and red oak (Quercus rubra) were planted in tree rows, intercropped with soybean (Glycine max). In the conventiona [...]

Amyotrophic lateral sclerosis (ALS) is reported to be probably linked to frontotemporal lobar degeneration (FTLD). Since FTLD is characterized by severe frontotemporal degeneration along with hippocampal atrophy (HA), the present study used post-mortem 7.0-tesla magnetic resonance imaging to investigate whether a certain degree of HA occurs in the ALS brains as well. The examined post-mortem brain samples comprised 9 from the ALS cases and 17 from the age-matched controls. The hippocampus samples were examined on t [...]

Epidermolysis Bullosa (EB) is a rare genetic disorder characterized by fragile skin that blisters and tears easily, leading to significant morbidity and mortality. Depending on the specific genetic mutations and the proteins involved, EB can be classified into several subtypes whose molecular complexity is compounded by the variability in mutation types (missense, nonsense, insertions, deletions), their locations within the genes, and the resultant effects on protein function. This systematic review aimed to identi [...]

Let’s consider the issues of exercise and cognitive function from a different angle, by moving from sitting to standing for instance. Not only does seeing anything from different perspectives reflect our cognitive flexibility [1], it also has a direct impact on the executive performance. Interestingly, recent studies reported a smaller Stroop effect when standing than when sitting [2-3] or after stepping backward [4], evidencing that the body posture enhances selective attention and cognitive control. Hence a call [...]

Here, we report the results of an investigation of the neuroprotective effects of securinine with tryptamine conjugate-allomargaritarine (2b), previously selected as the leading compound among a wide range of natural derivatives. 2b was synthesized from securinine using various Lewis acids as catalysts. In addition to the antioxidant and cytoprotective properties previously shown for 2b, in this work, in vitro analysis of the biological activity of the compound demonstrated that this conjugate is also able to influ [...]

The present study investigates the association between anger, stress, psychological distress and mood disorders among Egyptian entrepreneurs. Approach-wise, the study is quantitative, and its cross-sectional data were collected using a questionnaire. The study’s respondents are Egyptian entrepreneurs involved in several business activities. Hence, the study concluded based on 286 valid responses. We used analysis of moment structures (AMOS) software, where we conducted path analysis to conclude the results. C [...]

Climate change has a major impact on nature and influences ecological systems. The increase in the CO2-concentration in the atmosphere is a major driver of global warming. This study showed that global warming has a major impact on the release of pollen, and hence, on the people suffering from allergies in Switzerland. Basel is a station where long-term pollen observation is conducted, and the data was used to investigate the change during the last 52 years. There are stations throughout the world to measure the at [...]

Objective: Hematopoietic stem cells transplant (HSCT) requires being preceded by chemotherapy and radiotherapy. The neutropenia and thrombocytopenia which follows may be the possible cause of post-transplant complications. It is required that the patient undergoing transplantation is eradicated of any possible infectious focus. Currently, a uniform protocol for the oral management of these patients is unavailable. Methods: The approach for the dental management of each patient was designed as a more selective proto [...]

A 46-year-old, previously healthy woman presented via telemedicine with 14 months of progressive asymmetrical weakness, numbness, paresthesias and tremors. History and clinical exam findings suggested a peripheral etiology resembling a variant CIDP presentation. Electrodiagnostic testing identified only one motor nerve with signs of demyelination; the remainder of motor and sensory nerves were unable to be evoked. MRI showed diffuse enhancement of the trigeminal nerve and cauda equina. CSF revealed albuminocytologi [...]

Many sensible heat storage materials are regularly used as thermal energy storage (TES) systems to improve the efficiency of solar dryers. The present work focuses on the effects of the volume and particle sizes of a volcanic stone (pozzolan) for the same purpose. Samples soaked in matt black and without soaking were also considered. Heat charge and discharge tests were carried out by exposing the pozzolan contained in a solar collector of the direct solar dryer (DSD) and indirect solar dryer (ISD) to the sun. Char [...]
