Response to anti-SARS-CoV-2 mRNA vaccines in multiple myeloma and chronic lymphocytic leukemia patients.

Multiple myeloma (MM) and chronic lymphocytic leukemia (CLL) patients have increased morbidity and mortality rates of COVID-19 due to immunosuppression associated with the disease and ongoing therapy. The same immune impairment accompanying CLL and MM also affects suboptimal vaccine response. The study assessed the effectiveness of the humoral and T cell-mediated immunity following mRNA COVID-19 vaccination (using either BNT162b2 or mRNA-1273) in short-term (2-5 weeks after second dose) and long-term follow-up (12 weeks after vaccination).

The impact of time, environmental conditions, and sex on the degradation of bloody fingerprints on a glass surface.

Dactyloscopy is the branch of forensics that deals with identifying individuals by analyzing the configurations of the friction ridges on the fingertips. The persistence and degradation of fingerprints depends on such factors as the individual's sex and BMI (body mass index) and the duration and conditions of their preservation. There is a great deal of information on how the passage of time affects the image of fingerprints composed of sebum and sweat, but little knowledge concerning the preservation of bloody fingerprints.

Short-term effects of pesticide fipronil on behavioral and physiological endpoints of Daphnia magna.

Fipronil (FIP) is an organic pesticide with many practical uses. Although some results indicated toxic effects in some terrestrial and aquatic animal species, little is known on its influence on behavioral and physiological endpoints of cladocerans. The aim of our study was to determine the short-term effects of FIP at concentrations of 0.

Effects of L-proline on cellular responses of hen erythrocytes subjected to thermal stress.

Little is known on the protective effects of L-proline on hen erythrocytes. The aim of the study was to determine the protective effects of this amino acid at concentrations of 50 μg/mL, 100 μg/mL, 200 μg/mL in hen erythrocytes subjected to temperatures 41 °C, 43 °C and 45 °C for 1 h and 4 h. The following cellular parameters were determined: viability, morphological alterations, caspase 3/7 activity, heat shock protein HSP70 1A activity and glutathione level.

Behavioral and physiological responses of Daphnia magna to salicylic acid.

Salicylic acid (SA), a metabolite of acetylsalicylic acid is a monohydroxybenzoic acid a common non-steroidal analgesic and anti-inflammatory drug (NSAID) frequently detected in various aquatic ecosystems at concentrations up to 19.50 μg L in surface waters near livestock farms and 59.6 μg L in wastewaters.

Early morphological and apoptotic responses of bird erythrocytes to thermal stress.

Little is known about early indicators of heat stress in bird erythrocytes. We investigated the effects of elevated temperatures on the morphology and cellular responses of avian erythrocytes. Hen red blood cells were subjected to 22-45 °C temperatures for 1 h and 4 h, then stained and examined by light microscopy to assess morphological alterations.

Effects of L-proline on swimming parameters of Daphnia magna subjected to heat stress.

L-proline (L-PROL) is an essential amino acid, a constituent of many proteins and the osmoprotective molecule produced and accumulated in higher plants and some freshwater microalgae in response to various environmental stressors. Knowledge on thermoprotective effects of this amino acid on freshwater invertebrates is very scarce. Therefore the aim of our study was to determine the effect of L-PROL at concentrations: 10 mg/L, 20 mg/L and 50 mg/L on swimming behavior (immobilization, swimming track density, swimming speed, turning ability) of Daphnia magna subjected to temperatures: 22 °C, 35 °C and 38 °C.

Changes in Fingerprints and the Quantity of Material Forming the Print Depending on Hand Cleanliness, Gender, and Ambient Conditions.

Impressions of friction ridges left on a surface are important evidence for identifying an individual and can be used to confirm his or her presence at the scene of an incident. Factors influencing the durability of fingerprints include the physiological characteristics and cleanliness of the individual, environmental factors, and time. The aim of the study was to determine the effect of atmospheric factors, gender, hand cleanliness and time on the width of friction ridge impressions and the amount of material forming the print.

Inhalation poisoning with palytoxin from aquarium coral: case description and safety advice.

Palythoa spp. corals and some other marine organisms contain one of the most poisonous substances ever known - palytoxin (PTX). Due to their modest life requirements and ease of breeding, these corals are popular in home aquariums.

Changes in Fingerprints Depending on Physiological Factors.

The aim of the study was to determine the effect of gender, body mass index, and time on the width of friction ridge impressions in fingerprints and the content of sweat and sebum forming the print. The research showed that the friction ridge impressions of women are significantly wider than those of men, and this tendency persists throughout the existence of the print. The differences may result from the anatomical structure of the skin, as well as from the use of protective products such as creams, which are used more often by women.

Protective effects of compatible solute ectoine against ethanol-induced toxic alterations in Daphnia magna.

Ectoine (ECT) is a compatible solute synthesized mostly by halophilic microorganisms subjected to various stressful factors. Its protective properties in bacteria and some populations of isolated cells subjected to different stressors are reported; however, little is known on its effects against a commonly used compound, ethanol (ETH). The purpose of our study was to determine the effects of ETH alone (at 20 and 60 g/L) and in the combination with various concentrations of ECT (5, 10, and 25 mg/L) at various times of exposure on behavioural, physiological, and biochemical parameters of a model invertebrate Daphnia magna.
