Equity factors during the COVID-19 pandemic: Difficulties in emergency remote teaching (ert) through online learning.

Since the onset of the COVID-19 pandemic, () has become the prevalent form of learning at many universities worldwide. At the same time, voices around the world have pointed to in online learning in general and to concerns regarding in particular. The current study sought to increase knowledge about specific in ERT-OL and about the relationships between these elements from the standpoint of the following -, , and among students who are also parents or working.

[(EXPERIENCE WITH ALBENDAZOLE TREATMENT IN CHILDREN WITH CYSTIC ECHINOCOCCOSIS)].

The tolerability and efficiency of specific chemotherapy with albendazole were analyzed in 18 patients with cystic echinococcosis at various sites. The most common complication of albendazole treatment was its hepatotoxic effect. Al- bendazole chemotherapy during at least its 3 cycles was observed to be highly effective in preventing recurrent echinococ- cosis in children.

[Results of studies of human dirofilariasis in Russia].

Human dirofilariasis is a pressing health problem in Russia. By 2014, there have been as many as 850 Dirofilaria repens-infested people living in 42 subjects of the Russian Federation. One of the favorable factors for circulation and spread of invasion is a temperature of above +20-24 degrees C; when the latter is maintained during at least 20 days there may be 1.

[Pseudoinvasion and transient carriage of the larvae of arthropods and soil nematodes in humans: problems and consequences. The authors' observations and a literature review].

The paper describes cases of pseudoinvasion and transient carriageof the larvae of arthropods and geohelminths. It highlights the objective and subjective factors in the diagnosis of arthropod-borne diseases and geohelminthiasis, which give rise to misdiagnosis. Distinctions between real invasion, transient invasion, and pseudoinvasion are pointed out.

Determination of polychlorinated biphenyls in soil and sediment by selective pressurized liquid extraction with immunochemical detection.

A selective pressurized liquid extraction (SPLE) method was developed for a streamlined sample preparation/cleanup to determine Aroclors and coplanar polychlorinated biphenyls (PCBs) in soil and sediment. The SPLE was coupled with an enzyme-linked immunosorbent assay (ELISA) for an effective analytical approach for environmental monitoring. Sediment or soil samples were extracted with alumina, 10% AgNO3 in silica, and sulfuric acid impregnated silica with dichloromethane at 100°C and 2000 psi.
