Removal of synthetic dyes from wastewater is essential both from the environmental and human health point of view. A small concentration of synthetic dyes can reduce water transparency and consequently influence photosynthesis and alter aquatic ecosystems. Acid black 48 is an Azo dye that falls under the category of synthetic dyes used in the textile industry. With dyes, coffee wastewater has high chemical oxygen demand (COD) that can affect dissolved oxygen (DO) in surface waters. A mixture of wastes in surface waters creates a need to investigate the efficiency of existing treatment methods and optimize them. Adsorption using activated carbon is a conventional method used to remove dyes and heavy metals from wastewater. Industries prefer efficient and economical treatment methods to meet challenging effluent standards regarding COD, BOD, and intensity of color. The adsorption process was optimized using low-cost adsorbents in the current study, including peanut hull and onion peel, to treat a binary mixture of acid black 48 and coffee wastewater. After adsorption, microfiltration was used to remove any suspended solids from the wastewater solution. The performance of combined treatment processes for the color removal of the binary mixture was analyzed and compared using transmittance and absorbance. Treatment efficiency of adsorption using low-cost adsorbents was compared with powdered activated carbon. Apart from absorbance and transmittance, non-purgeable organic carbon (NPOC) values were analyzed to determine organic carbon removal in the combined binary wastewater. Experimental results indicated that Langmuir isotherm was the best fit for a binary mixture with an optimum dosage of 1.2 g using onion peel. The regression coefficient value was 0.82, and the uptake was 58.13 mg of binary mixture per 1 g of onion peel. The effective pH for maximum uptake of acid black 48 using onion peel for adsorption was 5.7. The increasing dosage of low-cost adsorbents adsorption improved in removing binary waste of dyes and coffee waste from wastewater. Adsorption using onion peel improved adsorbent performance up to 1.2 g dosage and steadily decreased beyond that. The adsorption capacity of onion peel was comparatively higher than the peanut hull based on the linear fit.

Desmoid tumor is a rare disease, which is histologically characterized by local invasion, monoclonality, and fibroblast proliferation; and clinically characterized by a variable and often unpredictable course. The treatment of desmoid tumor is mainly surgical resection, but the recurrence rate is high. In recent years, a variety of treatment methods, including endocrine therapy, surgery, radiotherapy, chemotherapy, non-steroidal anti-inflammatory drugs, targeted drugs, interferon and more, have been used and achieved certain curative effects. In addition, in view of the inertia characteristics of desmoid tumor, observation is also a first-line scheme recommended by multiple guidelines. In the past, the research progress of targeted therapy for desmoid tumor is relatively slow and the curative effect is limited. Thus, targeted therapy is usually used as a remedial treatment after the failure of other conventional treatment methods. However, in recent years, with the rapid progress in the basic research of targeted therapy, some new targeted drugs are increasingly used for the clinical treatment of desmoid tumor and have achieved good results. Herein, we described a patient with aggressive fibromatosis in the abdominal cavity. Following a combined treatment using anlotinib and celecoxib, the patient achieved a partial response with mild toxicity. Simultaneously, the patient’s pain symptoms completely disappeared. This case indicates that the combination of anlotinib and NSAIDs could be an effective treatment for desmoid tumor.

Scars can adversely affect the physical, mental and social well-being of the patient. Common treatments for scar removal include external treatments, chemical peels, mechanical resurfacing, laser resurfacing, injection techniques, physiotherapy, and surgical excision. The search for combined treatment methods is an urgent and priority direction. Methods of phoresis are in demand in the correction of scars, when changes in the structures of the dermis and hypoderm significantly reduce the penetration of topical drugs and allow to achieve a greater therapeutic effect.

The paper examines effective hybrid technologies that combine electrophysical and electrochemical methods and enable treatment of parts with different nomenclature. New treatment methods, electrophysical and chemical, are pre-defined for processing conductive materials. By introducing combined treatment methods that bring together ultrasound, electrochemistry and electrical discharge it is possible to boost the treatment process, solve fundamental process tasks that are demanded by industry, and improve the quality of the treated surface. An analysis of the electrical discharge drilling method with an ultrasonic field activation is carried out. The disadvantages of the combined treatment method with the application of ultrasonic oscillations to workpiece are identified. Recommendations are given on determining and justifying the effective application of each method by taking into account the degree of complexity of the treated objects, the materials used and the type of appropriate production. A hybrid electrochemical-electrical discharge CNC machine is developed.

An investigation of effectiveness of topical treatment of nonhealing chronic venous leg ulcers with propolis ointment was conducted. 56 patients were included in the study and randomized into two groups. In group 1, there were 28 patients (ulceration area: 6.9–9.78 cm2) treated by means of topical propolis ointment application and short stretch bandage compression. In group 2, there were 29 patients (ulceration area: 7.2–9.4 cm2) treated by means of Unna boot leg compression without topical propolis treatment. In the study, the efficacy of both treatment methods in patients with resistive venous leg ulcers was compared. The ulceration of patients from group 1 healed completely after 6 weeks of therapy in all cases. In all patients from group 2, the process of healing was longer but successfully completed after 16 weeks of the therapy. We found that an adjunctive propolis ointment treatment increases the efficacy of the short stretch bandage compression stocking, and this combined treatment is more effective than Unna’s boot compression alone.

Background: Alveolar osteitis is one of the most common post-odontectomy complications. An agreement is lacking regarding the relative merits of various treatment methods. Of these treatments were alvogyl and Zinc oxide eugenol after saline irrigation.Objectives: The aim of the current study therefore was to evaluate the efficacy of both agents.Methods: A total of 987 patients were categorized into 4 groups (I, II, III, and IV) according to pain severity (mild, moderate, severe, or agonizing, respectively). Each group was randomly divided into two subgroups according treatment method: Alvogyl (Alv) and Zinc oxide eugenol following saline irrigation (I+Z).Results: Although, Alv was palliative in group. I, I+Z was curative in group, I and palliative in group II. Both agents were ineffective otherwise.Conclusion: The author recommends I + Z over alv.
