ALCHEMI (Atom Location by CHannelling-Enhanced Microanalysis) is a TEM technique for determining site occupancies in single crystals. The method uses the channelling of incident electrons along specific crystallographic planes. This channelling results in enhanced x-ray emission from the atoms on those planes, thereby providing the required site-occupancy information. ALCHEMI has been applied with success to spinel, olivine and feldspar. For the garnets, which form a large group of important minerals and synthetic compounds, the channelling effect is weaker, and significant results are more difficult to obtain. It was found, however, that the channelling effect is pronounced for low-index zone-axis orientations, yielding a method for assessing site occupancies that is rapid and easy to perform.

Narrow Concentration Range

SummaryThe activity of several synthetic compounds, rated from good to poor (or inactive) fibrinolytic activators, has been assessed by two different commonly-used in vitro methods. Compounds shown to be active over a narrow concentration range in the hanging clot test were shown to be inhibitors of plasmin and trypsin in the casein-olytic test. The inhibitory activity of these compounds was shown to increase with increasing substrate concentration and apparent activity in the hanging clot test. Possible explanations and relevance of these observations are discussed.

Modern Greek

This paper discusses the formation of synthetic compounds with proper names. While these are possible in English, Greek disallows such formations. However, earlier stages of the language allowed such compounds, and in the modern language formations of this type are possible as long as they contain heads that are either bound roots or root- derived nominals of Classical Greek origin. The paper builds on the following ingredients: a) proper names are phrases; b) synthetic compounding in Modern Greek involves incorporation, and thus proper names cannot incorporate; c) by contrast, English synthetic compounds involve phrasal movement, and thus proper names can appear within compounds in this language. It is shown that in earlier Greek, proper names had the same status as their English counterparts, hence the possibility of synthetic compounds with proper names. It is further argued that the formations that involve bound/archaic roots are actually cases of either root compounding or root affixation and not synthetic compounds.

The current work the effect of Actara insecticide belongs to chemical family Neonicotinoid. The active component of thiamethoxam in three concentrations: 0.750 ppm, 1.5 ppm and 2.25ppm   on adult house fly salivary glands. Histopathological and morphological effects revealed important alterations produced by this insecticide in histological and morphology of the adult house fly gland tissue categorized by increasing gland duct lumen diameter. These alterations are possibly related with excretion function of salivary gland might be accountable for removing this insecticide. Results show thiamethoxam is a powerful insecticide that performances histologically in salivary glant tissue, triggering alterations in the glands  form, cytoplasm  with extreme vacuolation ,disruption cell membrane, obvious disorganization tissues cells, terminating in progressive deteriorating phase with changes in nucleus glandular cell's, such alterations occurred together in its size and form of gland, disintegration of nucleus, and presence of apoptosis(fragmentation) nucleus, accelerating the process of glandular degeneration ,and interfering with feeding process of house fly particularly when the peak concentration of  insecticide  was used.

Quasi Experiment

The implementation of food sanitation aims to eliminate the risk of contamination by microorganisms at different stages in the production and processing of food. House fly (Musca domestical) can act as a vector of tyfus disease, other stomach ailments such as dysentery and diarrhea, cholera, and skin diseases. Salt fish processing business is the largest part of traditional fish processing business especially in Senamabah Village, Muara Bengkal Sub-district, East Kutai Regency. Problems that arise from the traditional processing of salted fish with sun drying, have the weakness of one of the fly flies that can damage salted fish products especially during the rainy season. This research is a quasi-experimental research (Quasi Experiment Design). Field research is difficult to carry out randomization. For field research, usually using a quasi-experiment, this study used a Completely Randomized Design (RAL), consisting of 3 treatments with 1 control and 3 repetitions on each treatment. This research is about the effectivity test of pandan wangi leaf extract (Pandanus amaryllifolius Roxb) as Refellent Vegetable in Reducing Number of Flies during the drying process of Salted Fish, concentration 5% after 30, 60 and 90 minutes observation with the average percentage of moisture by 25% decline 55%, concentration 10% after 30, 60 and 90 minutes observation with the average percentage of up to 13% with 77% repulsion and 15% concentration after 30, 60 and 90 minutes observation with percentage of average 6% with 90% resistance.

No effective therapeutics to treat neurodegenerative diseases exist, despite significant attempts to find drugs that can reduce or rescue the debilitating symptoms of tauopathies such as Alzheimer’s disease, Parkinson’s disease, frontotemporal dementia, amyotrophic lateral sclerosis, or Pick’s disease. A number of in vitro and in vivo models exist for studying neurodegenerative diseases, including cell models employing induced-pluripotent stem cells, cerebral organoids, and animal models of disease. Recent research has focused on microtubulestabilizing agents, either natural products or synthetic compounds that can prevent the axonal destruction caused by tau protein pathologies. Although promising results have come from animal model studies using brainpenetrant natural product microtubule-stabilizing agents, such as paclitaxel analogs that can access the brain, epothilones B and D, and other synthetic compounds such as davunetide or the triazolopyrimidines, early clinical trials in humans have been disappointing. This review aims to summarize the research that has been carried out in this area and discuss the potential for the future development of an effective microtubule stabilizing drug to treat neurodegenerative disease.

: The novel coronavirus disease-19 (COVID-19), a global pandemic that emerged from Wuhan, China has today travelled all around the world, so far 216 countries or territories with 21,732,472 people infected and 770,866 deaths globally (as per WHO COVID-19 update dated August 18, 2020). Continuous efforts are being made to repurpose the existing drugs and develop vaccines for combating this infection. Despite, to date, no certified antiviral treatment or vaccine prevails. Although, few candidates have displayed their efficacy in in vitro studies and are being repurposed for COVID-19 treatment. This article summarizes synthetic and semi-synthetic compounds displaying potent activity in their clinical experiences or studies against COVID-19 and also focuses on mode of action of drugs being repositioned against COVID-19.
