Quantitative determination of the activity of acid phosphatase detected in tissue sections using Burstone's method. The experiment was performed on inbred rats. A reaction for AcP according to Burstone was made in liver sections, incubation time was fixed experimentally. The material obtained from each animal was divided into 3 parts. One of them was used for enzymatic estimations, the 2nd for planimetry of sections, and the 3rd was eluted by N,N-dimethylformanid, and the obtained coloured product was subjected to spectrophotometric analysis at the Spectrophotometer Unicam SP 8000 B. Homogeneity of the coloured product eluted from the sections as well as its identity with the coloured product obtained during the reaction with a preparation of crystalline acid phosphatase was found. Repeatability of the obtained activity for the inbred animals was shown. The obtained results were subjected to statistical analysis. The method of quantitative estimation of AcP activity may be useful in histoenzymatic works.

Magnesium (Mg) an essential plant nutrient is widespread deficient in the acidic soils of Nilgiris of Tamil nadu, India. The vegetable yield and quality is especially affected due to deficiency of nutrients like Mg. This study investigates soil characteristics and bacterial diversity in the Nilgiris district of Tamil Nadu, India, with respect to Mg deficiency.

Plastic pollution and global warming are widespread issues that lead to several impacts on aquatic organisms. Despite harmful studies on both subjects, there are few studies on how temperature increases plastics' adverse effects on aquatic animals, mainly freshwater species. So, this study aims to clarify the potential impact of temperature increases on the toxicological properties of polyvinyl chloride nano-plastics (PVC-NPs) in Nile tilapia (Oreochromis niloticus) by measuring biochemical and oxidative biomarkers.

Plants sense and respond to hyperosmotic stress via quick activation of sucrose nonfermenting 1-related protein kinase 2 (SnRK2). Under unstressed conditions, the protein phosphatase type 2C (PP2C) in clade A interact with and inhibit SnRK2s in subgroup III, which are released from the PP2C inhibition via pyrabactin resistance 1-like (PYL) abscisic acid receptors. However, how SnRK2s are released under osmotic stress is unclear.

The odontoclast is a rarely studied cell type that is overly active in many dental pathologies, leading to tooth loss. It is difficult to find diphyodont mammals in which either physiological or pathological root resorption can be studied. Here we use the adult leopard gecko, which has repeated cycles of physiological tooth resorption and shedding.
