Somatic symptoms associated with mental distress during the COVID-19 pandemic: a systematic review.

Objective: The primary objective of this article was to systematically review the prevalence of somatic symptoms in patients, healthcare workers and general population during the COVID-19 pandemic. The secondary objectives were to record the association between somatic symptoms and indices of mental distress and to record the qualitative characteristics of such somatic complaints.

Methods: Following the PRISMA methodology we systematically searched PubMed, Scopus and Google Scholar for primary research reporting on somatic symptoms in association with mental distress.

Evaluation of two pesticide leaching models in an irrigated field cropped with corn.

Pesticide leaching models is an easy and cost effective method used in the prediction of surface and groundwater pollution. In this paper, the ability of two pesticide leaching models, MACRO and PEARL, to describe soil water dynamics and atrazine's transport through the soil profile was examined. The data used for the comparison was obtained from an experiment in an irrigated corn field in the plain of the Ardas River, in north-eastern Greece.

Metastasis of colorectal adenocarcinoma to the thyroid: a case report and review of the literature.

Purpose. We present a rare case of colorectal metastasis to the thyroid five years following primary colonic resection. This case highlights the need to be cognisant of unusual sites of metastasis from colorectal neoplasms.

Water quality in irrigation and drainage networks of Thessaloniki plain in Greece related to land use, water management, and agroecosystem protection.

A representative agricultural area of 150 ha located in a protected ecosystem (Axios River Delta, Thermaikos Gulf-N. Aegean, Greece) was selected in order to investigate water quality parameters [pH, electrical conductivity (EC(w)), NO(3)-N, NH(4)-N, total phosphorus (TP)] in irrigation and drainage water. In the study area, the cultivated crops are mainly rice, maize, cotton, and fodder.

Efficacy and safety of ultrasonically activated shears in thyroid surgery.

Background: The purpose of this prospective study is to evaluate the efficacy of ultrasonically activated shears (UAS) in hemostasis as well as its safety in regard to complications in thyroid surgery.

Methods: Three hundred patients who had undergone surgery on the thyroid gland were divided into 2 groups of 150 patients each. Hemostasis as well as division of blood vessels and thyroid tissue were performed with the use of UAS in the first group and by conventional ligations in the second group.

Carcinoid of the ampulla of Vater--report of two cases.

Carcinoid of the ampulla of Vater is extremely rare, accounting for less than 0.3% of all gastro-intestinal carcinoids. To our knowledge, only 80 cases of ampullary carcinoid have been reported in the literature to date.

A Decision Support System approach for rivers monitoring and sustainable management.

This paper presents a Decision Support System (DSS) approach developed in the context of the Copernicus project entitled System for Water Monitoring and Sustainable Management based on Ground Stations and Satellite Images (WATERMAN). The main objective of WATERMAN is the monitoring and management of the Strymon River in the Southern Balkans. The specific DSS integrates the main components of WATERMAN and helps the decision maker to monitor the Strymon region; to control and forecast the quantity and quality of the river water; as well as to make objective decisions about the state of the water based on data provided by radio computers, earth stations and satellite images processed by mathematical and statistical models and Geographical Information Systems (GIS).

Metabolic alterations of skeletal muscle tissue after prolonged acute ischemia and reperfusion.

Acute tissue ischemia is usually followed by considerable disturbances of cellular metabolism that often lead to cell death. Reperfusion improves cellular function by withdrawing the toxic products of ischemia and providing energy sources, although sometimes it worsens it. The purpose of this experimental work is to study the metabolic disturbances in skeletal muscle tissue of canines after prolonged acute ischemia in relation to the values of certain substances (ATP, lactate, pyruvate, the ratio of lactate to pyruvate [L/P], and glucose) and whether the alterations in the values of these substances could be used as prognostic indices of the magnitude of tissue damage and the possibility of inverting it.

The use of extracellular enzymes from Streptomyces albus ATCC 3005 for the bleaching of eucalyptus kraft pulp.

The suitability of culture supernatant from Streptomyces albus ATCC 3005 for use in the biobleaching of eucalyptus kraft pulp was investigated. S. albus was found to grow on a minimal salts medium containing oat spelts xylan and yeast extract as the main carbon and nitrogen sources, respectively.

Dechlorination of chlorophenols using extracellular peroxidases produced by streptomyces albus ATCC 3005.

Streptomyces albus ATCC 3005 was found to produce higher levels of extracellular peroxidase activity (3.420 U mg(-1)) than previously reported for any other actinomycete. Maximum peroxidase activity was obtained after 72 h of incubation at a temperature of 30 degrees C in a liquid medium (pH 7.
