Resumen
Serotonin toxicity is a potentially life-threatening condition associated with a range of psychotropic medications, co-administration of specific combinations of agents and overdose of certain drugs. It is associated with a wide diversity of clinical signs and symptoms, including cognitive, autonomic and somatic effects, as well as serious complications, including possible death. Diagnosis is often challenging and requires a high index of suspicion. Differential diagnosis includes syndromes such as neuroleptic malignant syndrome. Management depends on the causal agent and urgency of clinical p

Platinum-based chemotherapies, such as cisplatin, play a large role in cancer treatment. The development of resistance and treatment toxicity creates substantial barriers to disease control, yet.

The aim of the work was to analyze the indices of endogenous intoxication in deep-pregnant cows and to identify the possibilities of their use as predictors of bronchopulmonary pathology in newborn calves. 29 cows were examined for 239-262 days of gestation and 29 newborn calves of the red-and-white Holstein breed. Bronchitis developed in all calves during the first month of life, and in 7 newborns it was complicated by pneumonia. Markers of endogenous intoxication of cows were analyzed: total and effective albumin concentration, serum MMP content, Kalf-Kalif leukocyte index of intoxication (L

Currently, there is a necessity for regular quality control over natural water bodies within the territory of industrial cities. The aquatic environment quality monitoring and the toxicity assessment of the water pollutants, in addition to the hydrochemical analysis data, require integral, biological indicators.

A graph is said to be a regular graph if all its vertices have the same degree, otherwise, it is irregular. Irregularity indices are usually used for quantitative characterization of the topological structure of non-regular graphs. In numerous applications and problems in material engineering and chemistry, it is useful to be aware that how irregular a molecular structure is? Furthermore, evaluations of the irregularity of underline molecular graphs could be valuable for QSAR/QSPR studies, and for the expressive determines of chemical and physical properties, such as enthalpy of vaporization,

Ovarian cancer is the fifth most common malignancy in the world’s female population and with the highest lethality index among gynecological tumors. The prognosis of metastatic disease is usually poor, especially in platinum-resistant cases. There are several options for the treatment of metastatic disease resistant to platinum derivates (e.g. paclitaxel, topotecan and pegylated liposomal doxorubicin), all of which are considered equipotent. Pegylated liposomal doxorubicin (PLD) is a liposomal form of the anthracycline antibiotic doxorubicin. It is characterized by more convenient pharmacokine

This compound demonstrated promising antimalarial activity (IC50 < 1 µg/mL), however, it was not devoid of toxicity. Thus, to reduce the adverse side effects of this natural bioactive molecule, a delivery strategy involving a nanostructure was formulated. Additionally, poupartone B-loaded liposomes were coated with heparin, a glycosaminoglycan that is known to target proteins on the surface of Plasmodium falciparum-infected red blood cells.

Free radicals are often associated with fibrogenesis, which occurs in various disease states. The purpose of this study was to determine whether captopril prevents paraquat toxicity in lung tissue. Paraquat alone increased the level of lipid peroxidation (LPO) and the activity of superoxide dismutase (SOD) after 4, 12, 24 and 72 h of administration.
