Hypophosphorous osteomalacia (HO) is a rare metabolic disease. Due to hypophosphatemia and insufficient production of active vitamin D, the bone matrix can not be mineralized normally. Its clinical symptoms are atypical. It is generally manifested in bone pain and muscle weakness in different parts. With the progress of the disease, it is very easy to have osteoporosis, pathological fracture, bone deformity and damage to the function of other organs of the whole body. The etiology can be divided into primary and secondary according to the pathogenesis [1]. The primary is often caused by genetic factors, which can be divided into X-linked dominant low phosphorus osteomalacia (XLH) and autosomal dominant low phosphorus osteomalacia (ADHR). The secondary cause can be low phosphorus osteomalacia (TIO) caused by exposure to some drugs or heavy metals and tumors. This disease is rare in clinic, so clinicians have insufficient understanding of the disease and are prone to missed diagnosis or misdiagnosis. This paper reports a case of adult female with low phosphorus osteomalacia. The diagnosis, treatment and treatment are analyzed and discussed in order to provide reference for clinic.

From ancient time peoples were using lipstick, which was made by natural sources to protect and to increase the beauty of lips. Herbal lipstick contains pigments, antioxidants, waxes, oils, fragrance and preservatives. Alkanet root is used as natural source of red pigment in cosmetics, food and textile industries. Alkanet roots are traditionally used to treat aging, wounds, inflammation and herpes. The herbal lipstick was formulated and subjected to evaluation by different parameters like breaking, melting and, softening points, surface anomalies, aging and perfume stabilities, solubility test and pH. The herbal lipstick presents quintessential properties after application. It was concluded that the formulated herbal lipstick provides less side effects and further clinical investigation is required to assess for better efficacy.

The present work represent potential bio-sorbent (banana and pomegranate peel) in nano size range, with a view to for adsorption of lead(II) ions from aqueous solution. Dose, adsorbate concentration, pH, time, and temperature factors were investigated. The most favorable stipulations for Pb (II) adsorption are 50 mg /L as initial concentration, 0.2 g as pomegranate and banana peels mass and pH 5.5 and 5.23for banana and Pomegranate peel. Removal data obey the Langmuir model with qmax of 25.64 mg/g for banana and 41.66 mg/g for Pomegranate peel. The kinetics of removal process was fitted well by a second -order equation. It was observed that that the Pb (II) ion adsorption process on the both bio-sorbents is spontaneous process, endothermic for banana while exothermic for pomegranate peel. A distinct improvement in the adsorbent surface was noted after adsorption process which demonstrated via scanning electron microscope.

Medicinal chemistry scientists` efforts and trials to discover a very potent anticoronaviral medicine specifically effective against the current frightening virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), are not over yet. Synthetic organic chemistry will remain one of the most important branches in the entire drug discovery science. (E)-N-(4-Cyanobenzylidene)-6-fluoro-3-hydroxypyrazine-2-carboxamide (Cyanorona-20), a newly-discovered favipiravir analog/ derivative, is one of the promising synthetic organic compounds that displayed very strong nanomolar potencies against this fatal coronavirus, reaching an anticoronaviral-2 EC50 of nearly 450 nM or 0.45 μM. This compound was found to act against the SARS-CoV-2 mainly through the powerful inhibition of the coronaviral RNA-dependent RNA polymerase (RdRp), via competitively occupying and locking this enzyme`s major catalytic active site pocket (the suggested primary mechanism of action). Cyanorona-20 is still under progressive investigation as an attempt to continue developing it as a prospective remedy for the coronavirus disease 2019 (COVID-19). However, the previous literature synthetic procedures of Cyanorona-20 were criticized for several reasons like the harsh handling, difficult separation, small yield, and low purity. Herein in this short-communication or technical-note article, more reproducible and efficient novel synthetic method for Cyanorona-20 compound is presented, in an effort to address almost all of the problems which were accompanying the preceding methods.
药物化学科学家的努力和试验还没有结束，他们正在努力发现一种非常有效的抗冠状病毒药物，专门针对当前可怕的病毒——严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)。合成有机化学仍将是整个药物发现科学中最重要的分支之一。(E)- n -(4- cyanoboblidene)-6-fluoro-3-hydroxypyrazine-2-carboxamide (cyanorna -20)是一种新发现的favipiravir类似物/衍生物，是一种有前景的合成有机化合物之一，对这种致命的冠状病毒表现出很强的纳米摩尔效力，其抗冠状病毒-2 EC50接近450 nM或0.45 μM。研究发现，该化合物对SARS-CoV-2的作用主要是通过竞争性地占据和锁定该酶的主要催化活性位点袋，从而对冠状病毒RNA依赖性RNA聚合酶(RdRp)产生强大的抑制作用(这是建议的主要作用机制)。Cyanorona-20仍在逐步研究中，试图继续将其开发为2019冠状病毒病(COVID-19)的前瞻性治疗药物。然而，以往文献中对Cyanorona-20的合成工艺存在操作粗糙、分离困难、收率小、纯度低等缺点。在这篇简短的技术笔记文章中，我们提出了一种重现性更好、效率更高的氰-20化合物的新合成方法，试图解决前面方法所伴随的几乎所有问题。

The electrooxidation of 1,2,4-benzenetriol was studied in different non-aqueous solvents. The results showed that the studied substance can be oxidized in several ways on the electrode surface due to the favourable positions of hydroxyl groups (similarly to hydroquinone, resorcinol and catechol). In most cases one anodic peak appeared involving all possible electrode processes. The concentration dependence of voltammetric peak currents using platinum macroelectrode showed nonlinearity attributable to the 1,3-oxidation similarly to resorcinol leading to partial deactivation. Appearance of more peaks indicated the weak deactivation at higher concentrations in acetonitrile and nitrobenzene. At higher concentration the microelectrode became deactivated as in the successive scans the currents declined continuously reinforcing the existence of resorcinol pathway.

Here the review converses the `molecular cross-talk` of biofuel production mechanisms for Staphylococcus aureus. Staphylococcus aureus is a leading cause of bacterial infections globally in both healthcare and community settings. The succes of this bacterium is the of an expansive repertoire of virulence factors in combination with acquired antibiotic resistance and propensity for biofilm formation. S. aureus leverages these factors to adapt to and subvert the host immune response. With the burgeoning fiels of immunometabolism, is has become clear that the metabolic program of leukocytes dictates their inflammatory status and overall effectiveness is clearing an infection. The treatment of S. aureus infections become complicated due to the capacity of S. aureus �multidrug-resistant� occurs because of biofilm formationon the surfaces depending on biotic and abiotic factors, genetic factors, and numerous environmental, which vary from species to species. A broad range of molecular phenomenon contributes a high range of recalcitrance that is insisting on the biofilm formation. The previous published literature illustrated that all strains of Staphylococcal sp. contain the �ica locus� and several can form biofilms in vitro condition. Absences of �ica locus� results diminish of capability to produce biofuels, along with `PIA gene`, or mediate `N-acetyl glucosaminyl transferase activity� in vitro condition.

Prediction of the flow pattern is a central problms in multi-phase flow analysis. It is a vital point for researchers to accurately predict which flow pattern category types will occur at different flow rates. For this purpose, a mathematical model using the MATLAB (R2017b) computer program is developed for the prediction of gas-liquid two-phase flow patterns in a horizontal pipe with an inner diameter of 30mm under standard conditions. The properties of the air-water two-phase, the pipe geometry, and the flow rates of phases are defined to initiate the operating conditions. The mass flow rates of air and water changed from 0.002 to 0.004 kg/s and 0.672 to 1.334 kg/s, respectively. The impact of properties of the fluid and pipe diameters on two-phase flow configuration is considered to predict the impact of fluid properties on the flow pattern. The findings indicate that as the mass flux increases, the pipe diameters decrease, affecting the configuration of the flow pattern types. The mathematical model�s predicted results are validated by comparing with previous studies. In addition, good agreement is obtained when the predicted results are compared to the ongoing experiment of this research.

Odors are considered as one of the most important environmental problems that may adversely influence the quality of life of people affected by their interaction. Due to the multiple sources of emissions, combined with the abundance of chemical compounds classified odor nuisance, new methods of reducing odor emissions are sought while maintaining environmental neutrality. One potential option is to use biochar, a sustainable, carbonized solid product resulting from the thermo-chemical treatment of biomass and/or organic waste. Due to its valuable properties (in particular, high specific surface area, and microporous structure), this material can be used for sorption purposes. Although the issue of using biochar to remove odor emissions is relatively new, in recent years new research directions have been undertaken to determine the sorption efficiency of biochar not only as a direct adsorbent but also in alternative applications. Therefore, this paper aimed to review the most important directions of biochar management in the removal of odor-causing compounds and to highlight the current advances undertaken in this direction. It was distinguished that biochar can enhance odor mitigation by being an additive to compost, a biofiltration medium, a direct adsorbent, a soil additive, a substrate for the production of the odor-absorbing product, a dietary supplement, and a biocover. However, further research is needed to strengthen the range of greater use of biochar in practice.
